The present invention refers to an automated restaurant plant.
The invention aims to create a new system for catering, where the people can spend some hours in high spirits when they can eat fine food.
On this base, a new system was designed, allowing the interaction of entertainment technology with the eating pleasure.
The invention, as descnpted in claim 1, will be better described by some preferred embodiments thereof, provided as a non-limiting example, with reference to the enclosed drawings, in which:
Figure 1 shows an embodiment of the plant of the invention.
The place with rectangular base (ref. n°l) where it is inserted the conveyor of the "apple- table" (ref. n°2).
The room takes up by the oval conveyor, for all its length and the width with the exclusion of four corners where are placed the entertainment area for the public, for reception point and for food serving.
Figure 2 shows the external view of the reception point. Over the entrance there is the symbol that identifies the room.
Figure 3 there is the view that the customer has when it enters the room.
Figure 4 there is all view of the room, where it can be seen the conveyor where over there are placed the "apple-table" (ref. 2). In the four corners, it can be identified the area for the reception of the customers (ref. 3), the area for the service at the table and for the preparation of the drink to be served at the table (ref. 4) at the side there is the kitchen (ref. 8).
At the opposite side, there is the area for the recreation of children (ref. 5)
In the corner with ref. 6 there is the area destined to insert the musical band for make live concerts or make video shown on the big screen.
Near at the entrance (ref. 3) there is an area for baths (ref. 7) where there is handicap bathroom (ref. 7a), female bathroom (ref. 7b) and male bathroom (ref. 7c).
At one side of the room there are the external aisles for the evacuation of the room in case of emergency (ref. 9 and 10). To describe the organization of the dining room and the kitchen of the restaurant, I want to create an "imaginary travel" of the customer. I will consider the customers expectation during the time that they stay in the room.
The customers are arriving in the room would be welcome for set a positive contact with to manage the restaurant. The customer might be received like in a wonderful fairy tale of Disney. The restaurant manager will arrange the arrival of your coach to make this fantastic travel, where your ticket is "the personal tablet" that is confined at the entrance and for the children there will be "the personal children tablet" with videogames and films on its.
For first time, it may be active a system of table managed that can be of two sizes for 6 or 8 persons. In the tables for 6 persons it is possible to stay with two or four persons without there is many detach.
Figure 5 shows the entrance hall (ref. 3) where the customer is received for assignment of their "apple-table".
Close to the entrance hall there is the ramp (ref. 15), it's built with 8% of inclination to allow the entry of the wheelchair for disabled people.
A leading (ref. 11) is positioned laterally to the conveyor to admit at the person on the wheelchair to go out of the dining room in independent way in emergency situation. It's built in iron covered with anti-skid material. It's a high of 1 cm high with a ramp of 8% of inclination.
The ref. "la" showing the position of the switch to start, stop and emergency stop of the conveyor rotation.
In the detail, there are the same reference with the view from above.
The apple-table when it arrives on the site the reception, it's stopped the rotation on itself and the customers can go up on "apple table". To avoid the conveyor starts and stops is well don't stop the system.
If it's necessary for the person on the wheelchair, it's possible to put the platform to allow the access. In the apple table for six persons it is possible to put one person on the wheelchair and at the apple table for eight persons is possible to put three persons on the wheelchair with three persons on the seat.
The platform for wheelchair is positioned if the part of the cover of the apple table with part of the seat are removed. In the apple table for six persons it is possible to remove only the lateral parts of an entrance, in the apple table for eight persons it is possible to remove the lateral parts at every entrance. The customers must do a first setting of the environment, they may choose the music and the sound level. It's made with the "tablet menu" that it sets the appropriate environment. Only one tablet will manage the audio system, all other tablets at the table will do a list. The sound level will be stopped at the maximum level with the possibility to assignee a different sound level for every track.
Afterwards, the customers will order their menus with the "tablet menu" where they will be offered recommend dishes and the available dishes and they will choose the drinks.
In the restaurant after an order has been made, it's normal to bring out the menu, in this restaurant it remains because it's necessary for setting sound level and choose the music or for entertainment. The most important thing it's that the customer, frequently, after made an order doesn't have the menu to integrate the order, he renounces that he wishes.
It's possible the installation of some electric control (magnet or transponder) on the tablet menu to prevent the tablet menu to be stolen. In alternative, it can use the position detector active in OS X to detect the position where is the tablet menu that was stolen.
Another option, that must do the tablet menu is the possibility to make separated counts or total bill for every table. It's possible for this request to be made before every customer orders the menu. In this way, the customer can see the its count in every moment to choose to do another order. This system allows the customers to stay in total relax because they know that are in an honest room.
Now, the customers may taste the food.
The orders are communicated to the kitchen where are creating some independent emplacements of work for every chef. The chefs have generic knowledge to make all dishes, but everyone has specific knowledge about some dishes. The head chef sends on the monitor placed over every work station the number and the types of dishes that they must prepared. When the dish is ready, it is placed in the exchange cabinet (fig. 6 ref. 250) between the kitchen and the dining room. The dishes will be delivered by the waiters.
The orders of drinks are communicated to the waiters of the dining room that are placed in a corner (fig. 4, 6 ref. 4) where there are the exchange cabinets (fig. 6 ref. 250) to keep the dishes warm prepared in the kitchen (fig. 6 ref. 8). In front of the exchange cabinets there are the draught drinks cabinet (fig. 6 ref. 13) and near at it there are the cabinets where are placed the bottles of wine (fig. 6 ref. 14) that they are for customers.
At the end of the dinner or the lunch the customers return the "tablet menu" and they will pay the bill. Figure 6 shows the service area at disposal of the waiters of the dining room where they receive the dishes by the exchange cabinet (ref. 250) placed between the kitchen and the dining room
In front of the exchange cabinet there is the draught drinks cabinet (ref. 13) for prepare the drinks order by customers
Figure 7 shows the area to the disposition for the leisure for the children (ref. 5) where it is possible insert some games for entertaining the children. An emergency exit near at this area allows an immediate evacuation.
An internal area, quieter and reserved, it's equipped with table for nursery and play at some games, (ref. 12).
Figure 8 shows the area for entertainment activities with maxi screen or for live concerts (ref. 6).
Description of table system:
Figure 9 shows the upper part as viewed by customer in the restaurant.
You can see the complete mechanical system for moving the apples-tables, where there are the apples tables placed on the united trolleys (ref. 70).
In the middle of the conveyor are placed three-central apples with autonomous rotation (ref. 210).
Figure 10 shows the complete mechanical system for moving the apples-tables with view by low toward high. You can see the complex system that is not seen by the customer of the restaurant.
The conveyor (ref. 70) is composed by trolleys, where only n°10 have the system for take up the motional force for the rotation of the apples-tables (fig. 25).
The three-central apples (ref. 210) are independently motorized to have the rotation on themselves.
This system is based on the handling of the table placed in a structure, it was built with an apple shape. This structure allows, besides to give a scenic effect, it creates soundproof area. Every apple-table is covered with plasterboard or a composed with marble dust covered with wax-cloth. It's covered inside with soundproof product.
This project wants to create a soundproof area for every table to avoid the noise created by several persons in a single room.
The main components that compose the system are:
- The external conveyor carries the structure for apples-tables (fig. 9 ref. 70). - The apples tables located in the middle of the room and the central area placed in the middle of the conveyor with independent rotation (fig. 9 ref. 210).
The handling of the tables placed on the external conveyor (fig. 9 ref. 70) is made with two manners:
- The apples tables advance in the dining-room to carry out an oval track with two curves at 180° and two rectilinear strokes.
- The apples tables rotate on themself during the advance.
The apple-table is a common element, it's applied on the conveyor and on the central structure. It can be made in two different ways for 6 or 8 persons.
The apple table for 6 persons is composed with different elements:
- The carpentry structure is bringing the external covered, (fig. 12 ref. 27, 28, 29).
- Three circular seats placed around the circular table, (fig. 12 ref. 24, 25, 26).
- A circular table with a tablet case for every person (fig. 12 ref. 33).
Figure 11 shows the apple table for six persons, it's composed by:
External covered made with plasterboard or with marble dust covered with wax-cloth (ref. 21) places on the carpentry structure that inside has a soundproof product named Fiberfon of the Angst-Pfister with Class 1 of fire reaction.
A platform is brought of wheelchair for person, it's created an extension of the trampling top to permit the disabled person to sit at the table, (ref. 23)
A lid covers the upper space where are placed the electronic equipment to amplification sound for data transmission with Wi-Fi (ref. 22).
The second view of the picture shows the apple table for six persons without the application of the platform for disabled person. It can be seen the apple structure with the extractable parts applied (ref. 34 and 35), they are removed for application of the platform for disabled person (ref. 23). The functioning and components of the extractable parts are equal to the same as the extractable parts for apple table for 8 persons where is described in more detail but they are different for the shape.
Figure 12 shows the "apple-table" for 6 persons sectioned in three different levels to show the structure and the distribution of the internal space.
The first section "A" is made over the table level, it can be seen the accommodations of the persons in the structure. In the section "A" of the picture are shown the table (ref. 33) with the trapezes with major base of 450 mm, it's the representation the space available for each person. The wheelchair for disabled person is positioned on the platform (ref. 23). Part of the seat is taking away that it positioned in guide rail placed at the lateral seat and it's fixed by hook clamps.
In this specific case, the ref. 26 is the complete seat, while with ref. 24 and 25 are the seats having the extension. In the figure are removed for do place the platform for disabled person.
The structure assembly of the apple table is composed by soundproof (ref. 27), steel structure (ref. 28) and external covered (ref. 29).
The second section "B" of fig. 12 is made under the level of the table and beyond the previous reference you can see the covered in wood 5 mm of thickness (ref. 32).
In the third section "C", you can see the base (ref. 31) in wood where they are made the grooves for passing the electric cables (ref. 31a) from the middle of the base until external position. The electric cable passes through the hole (ref. 28e) and it goes up in the structure with ref. 28.
Figure 13 shows the soundproof (ref. 27) product of the Angst-Pfister named Fiberfon and placed in the internal structure iron (fig. 12 section "A" ref. 28) that has function of support.
Figure 14 shows the external covering made with plasterboard (ref. 29) or composed with marble dust covered with wax-cloth. It's placed on the carpentry structure (fig.12 section "A" ref. 28 and fig. 15).
The ref. 22 is the lid put on the plasterboard cover (ref. 29), it allows to create a space. Figure 15 is the view of the supporting structure in iron (ref. 28). It has a circular base (ref.
28a) realized in folded sheet, it's screw on the wood base (fig. 12c ref. 31) of the rotating structure of the trolley.
The welding plate (ref. 28b) serves to bring the guide rail for the removeable part of the seat.
The upright (ref. 28c) is realized in square tubolar, it carries the plasterboard, the soundproof product. Inside them there are the passages of the electric cables.
The plate (ref. 28d) serves to join the supporting structure and on it there is the cover plasterboard (fig. 14 ref. 29).
The apple table for 8 persons has a structure similar at apple table for 6 persons. To avoid expand the structure, it's necessary to broaden the support base without broaden the maximum dimension of cluttered. A short analysis to illustrate the principal characteristics and the little differences. The structure is composed by this element:
- A base in wood (fig.17 ref. 46) screws and paving on the iron base of the trolley (fig. 28 ref. 89).
- A carpentry structure in steel (fig. 17 ref. 44) beams of the coating and soundproof, on it is fixed the seat (fig. 17 ref. 45) and at the centre is placed the table (fig.17 ref. 43). A difference between the structure is that the base for 6 persons has a dimension less reduced than the base for 8 persons. Furthermore, in the apple table for 8 persons it's possible to remove the laterals parts (fig. 16 ref. 40 and 41) in every entrance for positioning three disabled persons while in the apple-table for six persons it's possible to remove the lateral parts in only one entrance for positioning a disabled person.
The table shown in figure n°17 is designed for positioning of 9 persons with a distance of 440 mm, in the reality the system might be used with 8 persons, it gives a better distribution of the space for every person, (fig. 17 section "A" ref. 43).
The management of sound system and the order transmission of the customers is made with the same way of the apple-table for 6 persons.
Figure 16 shows the structure of 8-person apple table as similar as structure at 6 persons. It's composed by a steel iron (fig. 16 and 17 section "B" ref. 44), its border is made with plate fold and it's screwed on the wood base (fig. 17b ref. 46). On it, there is a wooden floor (ref. 37) to cover the passages of electrical cables for power supply of electronic devices.
The platform (ref. 38) has the function to broaden the bearing base for admission of the disabled persons at the table. It's applied if they are removed the extension (ref. 40 and 41), another possibility is put the swivel stool (ref. 62) for deploy in the better way the space of persons at the table (ref. 43).
Figure n°17 shows different sections of the apple table for 8 persons.
In the first section (A) you can see the benches (ref. 45), where are removed the extension (ref. 40 and 41) to place the platform for disabled person (ref. 38).
The apple table is composed by soundproof sheet (ref. 48), structure in iron (ref. 44) and cover in plasterboard (ref. 39).
The swivel stool (ref. 62) is necessary to complete the capacity of the table. It's removable to put the children stool. The second section (B) is made over the base where are placed the rollers (ref. 47) necessary to support of the base extension (ref. 46) for the 8-person apple table. The ref. 46a indicates the grooves for electric cables.
The third view "C" shows by low the 8-person apple table where on the base (ref. 46) are placed the rollers (ref. 47).
The ref. 62 is the swivel stool and the ref. 38 is the platform for wheelchair.
Figure 18 show the removeable parts for the installation of the platform for disabled person (ref. 40 and 41), they are connected at the back seat back (ref. 57) with an iron carpentery. Everyone has a handle to ease the extracting.
Every seat bench has over it the latch clamps with ref. 49 for the blocking of the extension bench seat when it's insert in the side. A carriage (ref. 55) is applying on the extension seat bench (ref. 57) and it allows the centering in the guide rail (ref. 58) placed lateral at the seat bench.
The swivel stool (ref. 62) is placed without remove the removeable parts (ref. 40 and 41). Details of the components placed in apples tables:
The structure of the apple-table is designed for sound-proofed in the better manner the habitat where are seated the persons.
In the internal structure is placed the soundproof (fig. 17 ref. 48 or fig. 12 ref. 27) applied on the covering.
Over the plasterboard cover (fig. 17 ref. 39 or fig.12a ref. 29) are placed the electronic devices for sound system covered by lid (fig.14 ref. 22).
The data transmission is made with Wi-Fi system. It allows to access to the server to listen musical tracks through "I-Tunes" circuit, see the video or play with videogames that the customer sees on the tablet menu.
The system for data transmission with Wi-Fi it allows the transmission of orders by the customer's table at the master chef in the kitchen.
The order of the dishes by the customer is made with a menu applied on the tablet. It permits an optimization of the flow of the orders.
Automatically it will be made a sorting, the drinks will be send on the monitor emplacement placed in the beverage area (fig. 6 ref. 4), while the order of the food will be sent to the console placed in the kitchen (fig. 4 ref. 8) and the master chef will put through the different chefs. When the dishes or main course (if the portion is for more person) are ready, the chef places it in the exchange furniture (fig. 6 ref. 250). This furniture has two tops for put 8 dishes for every apple-table. The selection of the table is made with the lateral buttons and through the slide of the tops. The top required will stop in front of the chef. It's where he must put the dishes, that it's the number of the table of the customer or the number of the chair of the customer.
Placed the dishes inside the exchange furniture, the chef signals the availability of the dishes to the waiter in the dining room. The waiter will bring the dish at the table when it will arrive near at the beverage area (fig. 6 ref. 4).
In this system of tables handling of the customers are applied some precaution for disabled person.
The rotation system is connected by a clutch, mainly to increase the security (fig. 27 ref. 85 and fig. 30 ref. 99) or if the customer doesn't want the table rotation on itself.
For the disabled person is possible the placement of a platform (fig. 16 ref. 38 for 8-person apple table and fig.l 1 ref. 23 for apple table 6 persons) to extend the base of the apple table. The platform is assembled with a base (fig. 21 and 22 ref. 52 and fig. 19 and 20 ref. 59) with two pivots in the lower part (fig. 21 and 22 ref. 52a and fig. 19 and 20 ref. 59a). The pivots are put in the housing made on the border of the metal structure (fig.11 ref. 28 or fig. 16 ref. 44) of the apple. After the positioned in the housing, the platform is connected to the electric contacts to supply the direct current at the proximity sensor (fig. 20 and 22 ref. 61) and to take direct current for the electromagnet (fig. 19, 20, 21, 22 ref. 50) that it supports the pivoted plate.
The platform carries the weight applied on it through some rollers positioned in the lower part (fig. 20 and 22 ref. 60) of it. Those rollers rolling on the floor of the trolley that allow the rotation of the apple table.
The pivoted plate (fig. 19 and 21 ref. 54) allows the access at the mezzanine of 30 mm. If the pivoted plate is lowered (fig. 19 and 21 ref. 54) active the proximity sensor (fig. 20 and 22 ref. 61) that it activates the clutch (fig. 27 ref. 85 and fig. 30 ref. 99). When the clutch is activated the rotation of the apple table is stopped because the rotation system doesn't power take by the motion of the trolley (fig. 27 ref. 75). The middle apples, that place in the mezzanine, are stopped if at the engine is took away the current and if it's necessary the brake engine is activated. If the pivot plate is lifted (fig. 19 and 21 ref. 54) the proximity sensor is disabled and the pivot plate is hooked by one or two magnets. The magnets powered by direct current hold the pivot plate with a force about 200 N (fig. 20 and 22 ref. n°50). If the pivot plate is lifted, it has the function to prevent the descent of the wheelchair during the rotation. If the disabled person pushes back with a force over 200 N the plate fall down activing the proximity sensor that it closes the clutch (fig. 30 ref. 99) and the rotation of the apple table is stopped.
The disabled person can open the device, if necessary. For the unlocking of the device are pressed the buttons on the magnets (fig. 19 and 21 ref. 50) that interrupt the direct current and the plate falls down.
The dimension of the base varies between the 8-person apple table (fig. 21 and 22 ref. 52) and 6-person table (fig. 19 and 20 ref. 59). It's necessary to create two different platforms (see di follow figure) but conceptually they have the same function.
Figure 19 shows the platform disabled person for access at the 6-person apple table. The platform is composed by a flat surface in iron plate (ref. 59). It has two pivots (ref. 59a) welded in the lower part. They are positioned in the hole over the border of the metal structure (fig.11 ref. 28). Three hinge have the function to join the flat surface (ref. 59) with the pivot plate (ref. 54) that it has laterally fixed the polar plate (ref. 51) to allow hooking on the electromagnet (ref. 50).
In the figure you can see the device in two position, closed and open to allow at the wheel chair going up (trasparent modality).
Figure 20 shows the platform with other view of the 6-person apple table. In the figure you can see the device (ref. 54) in two positions, closed and open, to allow the wheel chair going up (trasparent modality).
The flat surface (ref. 59) with the positioning pivots (ref. 59a) is joined through three hinges at the pivot plate (ref. 54). Under the flat surface (ref. 59) are inserted three rollers with pivot (ref. 60) to support the weight.
The polar plates (ref. 51) are attached to the pivot plate (ref. 54) to allow hooking on the electromagnet (ref. 50).
The proximity sensor (ref. 61) is open when the pivot plate (ref. 54) is lifted and it's closed when the pivot plate (ref. 54) is lowered and it interrupts the rotation.
Figure 21 shows the access platform for disabled person to 8-person apple table in position closed and opened. You can note that the base (ref. 52) has reduced dimension but its working is unchanged. Figure 22 shows the platform for disabled person to 8-person apple table with view by bottom towards upper. You can see the support (ref. 52) rollers that take the load during the rotation (ref. 60), the proximity sensor (ref. 61) signal the opening of the pivot plate (ref. 54).
The removable seat (fig. 23 and 24) for the 6 or 8-person tables allow to have a better distribution of the persons within the maximum capacity in such a way to place some removable seats.
Figure 23 shows the chair for 8-person apple table that is positioned in the supporting structure. It's possible inserting the pivot (ref. 63a) in the carpentry (fig. 16 ref. 44). It's composed with a plate base (ref. 63) on it is welded the pipe. The lever (ref. 65) adjusts the height of the seat (ref. 66) through the system composed with collar bearing and ball bearing.
Figure 24 shows the chair for 6-person apple table positioned in the supporting structure inserting the pivot (ref. 64a) in the supporting structure (fig.11 ref. 28). It's composed by a plate base, the pipe bearing of the seat is welded over of plate base (ref. 64) and under it there are a bearing rollers (ref. 60), they have the function to reduce the load embossing because the plate base of the chair is higher than the plate base of 8-person apple table. The lever (ref. 65) adjusts the height of the seat (ref. 66) through the system composed with collar bearing and ball bearing.
The Moving system is composed by trolleys, they are leaned on the pneumatics beam for the transmission of the progressive moving. The trolleys are of two types, one type carries the apple- table (it shows in fig. 25) and one type with only floor (it shows in fig. 35).
The trolley with only floor has a structure similar at the trolley with apple-table but there isn't the device for the rotation of the apple-table.
The trolley load of bearing of the apple table is composed by a carpentry frame (fig. 27 ref. 83) and at their sides there are two sliding blocks for taking the force of the advance motion (fig 27 ref. 83a and 83b).
- On one side there is a tyre for taking the motion force necessary for the rotation of the apple table, (fig. 27 ref. 75)
- The floor of the trolleys can be realized with any materials (fig. 27 ref. 73) but it must have a floor loading capacity as per current regulations. It is leaned on the APSOvib rubber metal rails (fig. 33 ref. 111, 112, 113). The frames of the trolleys are placed laterally and the contact area that has circular form are placed of the rollers (fig. 27 and fig. 35 ref. 78) bearing to allow pushing without the scraping between them. To avoid the accumulation of dust in the area some machining with a tooth shape are foreseen the below area on the semi-circular extremity of the floor (fig. 27 ref. 73). This machining doesn't allow the scraping with adjacent zones because there is some millimetre of space.
The load actions on the trolleys must the weight of the person, the complete structure of the apple table, is loaded in first time on the beams pneumatics (fig. 42 ref. 140 and 141) with a 12 mm of compression. The weight, after, is discharged on the wheels (fig. 27 and 35 ref. 74) without heavy duty swivel without offset suitable, they have a function to reduce the load on the pneumatic beams, it limits the flexion the frame of the trolley (fig. 27 and 35 ref. 83). An absorbing plate is placed between the carpentry structure and the wheel, it allows a better distribution the load weight on the wheel (fig. 36 ref. 118).
While to assure a constant compression of the pneumatic of 12 mm are placed of the guides rails (fig. 45 ref. 148, 151 and fig. 54 ref. 171, 172) over the beams pneumatics and over there are acting the roller placed on the frame of the trolley that it's adjustable with outlying pivot (fig. 27 and 35 ref. 76, 77).
The application of this system allows to keep always constant the position of the upper plane of the trolleys and also the force performed by beams pneumatics (fig. 42 ref. 140 and 141). Otherwise it would be proportional to the load force applied on the floor of the trolley. It's adjustable lifting the beams pneumatics with increase the compression of the pneumatics (fig. 42 ref. 140 and 141).
In the middle of the trolley there is a group for the rotation of the table apple that is assembled with a circular base over it there are two bearings CCW (fig. 28 ref. 92) positioned inside the support. This type of bearing allows some misalignments of some degrees, it can be due to irregular repartition of the weight on the upper base. They have the function of driving the system of rotation of the structure apple table (fig. 27 ref. 84).
The supporting structure for the rotation is composed by a pivot (fig. 28 ref. 86), it's drilled to allow the passage of the electric power supply. The pivot is fixed on a support plate (fig. 28 ref. 89). To reduce the transmission of the vibration between the apple table and the plate of support is put a plate realized with special material type Apsopur (fig. 28 ref. 88).
At the internal side of the trolley is positioned the pneumatic (fig. 27 ref. 75) for taking the power to the rotation that it acts on the rail guide vertical (fig. 54 ref. 188 and 191) positioned at the side of the beams internal pneumatics. The pneumatic that take the power is kept by a roller bearing of countercheck (fig. 27 ref. 81) that it acts on the internal superficies of rail vertical (fig. 51 ref. 144).
Under the tyres group positioned there is the group for taking current (fig. 27 ref. 79) it acts on two different rails placed under the rail guide vertical (fig. 51 ref. 167) for taking the power of the rotation. The arms of power supply (fig. 29) are kept in compression on the rail with the force performed by a gas spring (fig. 29 ref. 97) to guarantee always the taking of power supply in curve and in rectilinear (fig. 51 ref. 167).
Figures n° 25 show the two trolleys with the apple-table. In the first figure is possible to see the trolley with apple table for 8 persons that it is differenced by 6-person apple table for have a bigger base.
The references are reported on the figure are identical for both figure at demostration the similitude between the trolleys:
The apples tables at 8 (ref. 20) and 6 (ref. 21) persons are placed on the floor loading (ref. 73). The floor is put on the frame of the trolley with wheels with swivel forks without offset suitable (ref. 74), at the side of the wheel are located the metal sheets to limit the maximum rotation (ref. 87).
The arms for taking the current (ref. 79) of supply rails that are placed under the rail vertical on it acts the pneumatics (ref. 75) for taking motion for the rotation of the apple table that it through a crown wheel trasmits the force rotation by means of chain (ref. 80) at second crown wheel positioned on the clutch group, it's placed on the same shaft of the pignon placed at the side cog-wheel positioned under the group for rotation the apple table.
The roller bearings (ref. 76 and 77) are positioned at the side of the frame that they have the function to made a reaction on the upper guide to guarante a compression of the pneumatic of the beams pneumatics (fig. 42 ref. 140 and 141) on the knurled block of the frame. The roller bearings (ref. 76 and 77) are adjustable with eccentric pivot, in the normal postion it allows of 12 mm of compression of the pneumatics.
The lateral roller bearings (ref. 78) with eccentric pivot have the function to avoid the creeping between the frames of the trolleys.
Figure 26 is a lateral view of the power supply electric and the force taking of the apple table composed with these elements: On the frame (ref. 83) is welded a sliding (ref. 83b) of motion take off force for progress positioned under the floor (ref. 73). The roller bearing (ref. 77) is positioned at the side of the frame that it has the function to make a reaction on the upper guide (fig. 55 ref. 171 and 172).
The pneumatic (ref. 75) has the function to power take-off, the force is transmitted across the chain (ref. 80) to make the rotation of the apple table, the its compressed is made by roller bearing positioned on the eccentric pivot (ref. 81), it acts on the vertical guide rails (fig. 55 ref. 188 and 191).
From the arms for electric taking (ref. 79) by the rails go out the electric cables and they pass in the pipe (ref. 82) to arrive in the middle of the rotation structure.
Figure 27 there is a view of the components of the trolley by bottom towards top. It can seen the interaction of the different components:
On the frame (ref. 83) are welded the knurled blocks for power taking to the motion (ref. 83 a and 83b), the frame bring the floor (ref. 73) at the side of it are placed the roller bearings (ref. 76 and 77) that they made a reaction on the upper guide (fig. 46 ref. 148 and 151) for assuring the compression of the pneumatics. The pneumatic (ref. 75) acts on the vertical guide, on the internal side of the guides act the roller bearings (ref. 81). The frame (ref. 83) leans on the wheels (ref. 74) with iron sheets for checking the maximum rotation. The pneumatic group (ref. 75) has the function to power taking and it transmits by means of the chain (ref. 80), the tensioner of chain (ref. 130) guarantee the transmission of the rotation force at the crown wheel positioned on the clutch (ref. 85). The pinion on the shaft of the clutch transmits the power at cog-wheel (ref. 84) placed under the rotation group.
From the arms for electric taking (ref. 79) by the rails go out the electric cables and they pass in the pipe (ref. 82) to arrive in the middle of the rotation structure (ref. 84).
The base (ref. 46) of the 8-person apple table (ref. 20) is bigger than base for 6 persons (ref. 21) for this are placed three roller bearings that have the function of support (ref. 47). The plate welded in the middle of the frame (ref. 83c) serves to screw the extendable arms (fig. 39 ref. 123), they join the trolleys.
Figure 28 is the section made on the rotation axe of apple table, it show the components of the trolley. The base in wood (ref. 31) joins at the iron base (ref.89) with screws and pins. Between the wood base and iron plate is placed the sheet of absorbed of vibration (ref. 88). Under the iron plate (ref. 89) are placed the rotation wheels (ref. 90) and it is bolted with screws and pins on the pivot (ref. 86). The weight of the structure is downloaded on the structure of the trolley and not on the bearing (fig. 28 ref. 92).
The shaft (ref. 86) carries the bearings at orientable rollers (ref. 92) have the function to keep centred the rotation of apple table. This bearing type allows a few degrees inclination. The bearings are positioned in the support centre on the frame and at the their side there are the wheels of rotation. On the low of the shaft (ref. 86) is bolted the cogwheel (ref. 84) fixed with screws and pins.
The pipe (ref. 82) carries the electric cables for the power supply, it enters in the middle of the shaft (ref. 86). It allows to bring the direct current at the apple table that it arrives by arms of current (fig. 27 ref. 79)
The trasmission of the power taking, previous described, it made with clutch group (ref.
85) complet of pignon for chain (ref. 80) that it powers take off for motion from pneumatic group (fig. 27 ref. 75).
The arms allows to take direct current by rails, it's a complex system because the trolley makes two different paths, the first is rectilinear (fig. 59 ref. 195) and the second is curve, (fig. 59 ref. 194).
In order to ensure the taking of current for every phase, the device is made with two different arms (fig. 29 ref. 95) hinged with the bearings on the support (fig. 29 ref. 96). Every arm has a spring gas (fig. 29 ref. 97), it allows to exercise a constant pressure at its roller (fig. 29 ref. 94) that it contacts with the rail (fig. 59 ref. 194 and 195).
A special charcoal (fig. 29 ref. 93) it's positioned in the support and it takes in contact on the roller (fig. 29 ref. 94) through the force exercised by spiral spring. The pivot is screwed on the charcoal, it serves for taking the current and for keeping the position of contact with roller. Some protections in nylon or plastic (fig. 29 ref. 98) are moving with the arms (fig. 29 ref. 95) to guarantee that the sparks don't go out by contact area the roller with the rails.
Figure 29 you can see the composition of the arms for taking direct current describes in the previous paragraph.
The clutch group (fig. 27 and 28 ref. 85) is necessary because the conveyor of the apples- tables is moving with continuous linear motion, it can be stopped only in cases of security, considering the total mass that it must transport.
The rotation system is always continuous, it's necessary to put a device to interrupt the rotation of the apple-table in same cases. For example, it's necessary to interrupt the rotation to position the platform for disabled person and to permit the access of it, or it's necessary interrupt the rotation when the pivot plate, that it stops the wheelchair, it falls down because it's kept by electric magnetics or if it falls down, for security causes pushes by person on the platform for disabled person.
For obtain this system it's necessary insert a clutch among power take-off by horizontal pneumatic (fig. 27 ref. 75) and the cog-wheel positioned on the shaft for the rotation apple table (fig. 27 ref. 84).
The power take-off for motion is made by a chain (fig. 27 ref. 80) from pneumatic group (fig.
27 ref. 75), it is transmitted at the crown wheel placed on the clutch group (fig. 27 ref. 85), it's fixed with spline on the shaft for transmitted the motion at the cog-wheel that it engaged on the cog-wheel (fig. 27 ref. 84) placed under apple-table.
Figure 30 is the view of the clutch group apply on the trolley.
The central shaft (ref. 103) is positioned with bearings in the support (ref. 102). The clutch (ref. 99) is fitted together on the shaft (ref. 103) through spline (ref. 104). The crown wheel (ref. 100) is bolted with screw e pin at the clutch (ref. 99).
The crown wheel (ref. 100) is receiving the motion by chain and it transmits to the clutch. The clutch is placed at the correct height with spacer (ref. 106) that it leans on the cogwheel (ref. 101). The pinion (ref. 101) receives the rotational motion by spline (ref. 105) positioned on the shaft.
The support of clutch group (ref. 102) is bolted to the frame of the trolley (fig. 27 ref. 83) by means of the support where inside it is placed the bearings supporting the shaft (ref. 103).
The horizontal pneumatic group to bring in rotation the apple table, it takes driving force of the motion during the moving and it transmits it at the rotation system.
The vertical guide rails are placed on the external tyre beaming (fig. 54 ref. 188 and 191), on of it is exercised the pressure for taking driving force. The intensity of driving force is proportional at the height of the pneumatic is deformed. The deformation is guarantee of the roller bearing that it acts on the internal vertical rail (fig. 27 ref. 81).
Figure 31 is the pneumatic group is composed by tyre (ref. 109) that takes the driving motion by vertical rail. It's placed on the external of the pneumatics beam motorized. The rotational motion is took by tyres beam is transmitted at the crown wheel, (ref. 107).
The support (ref. 110) carries the bearings, inside bearings there is a shaft and at its external is positioned the pipe (ref. 108) divide in two parts, every part is fixed with spline. Every part of the pipe (ref. 108) has a flange. On the flanges is positioned the tyre
(ref. 109) and the crown wheel (ref. 107).
The floor applied on the trolley (fig. 32) carries apple-table, the floor that is applied over the trolley frame, is made of wood or composed material with a resistance of loading by regulations applied on APSOvib rubber metal rails.
This particular structure is made with two semicircles of equal radius placed at a distance "1" connected by two rectilinear tracks at the axe of translation, at the extremity the aim generated by the union of semicircle and rectilinear tracks is joined with two different radiuses.
The radius identifies with ref. "73a" fig. n°33 is lower than radius identifies with ref. "73b" because it's positioned on the external radius of the conveyor, and if it's minor the external profile is more similar at a circle and the guide upper (fig. 5 ref. 11) that it covers the conveyor on external side is narrower.
The radius "73b" fig. n°33 more is lower more to allow at the trolleys to join and the conveyor might make lower radiuses.
The floor has the working at shape of tooth on the circular profile. It allows a superposition of the floors placed over the trolley that it composes the conveyor. On the floor is made a circular seating ref. "73c" fig. n°33, the circular side is centring on the circular plate where there is the circulation of the wheels loading and for taking transverse forces generated by the loading applied on its.
Figure 32 is the upper view of the floor (ref. 73) of the trolley bring of the apple table. You can see the machining (ref. 73c) that it receives the rotating base. It can be realized with different material but it must have the resistance at the loading demand by regulations.
Figure 33 is the lower view of the floor (ref. 73) placed on the trolley with the its particular form.
The ref. n°l l l show the APSOvib rubber metal rails positoned in the specifics housing with forms "c" welded on the frame of the trolley (fig. 27 ref. 83).
The ref. n°112 and 113 show the external rubber metal rails positoned in sheet iron that are bolted on the trolley (fig. 27 ref. 83) while the rubber metal rails placed at side of the floor are bolted with wood screws on the floor (ref. 73) of the figure. With this system it permits the screwing of the floor after they are placed.
Figure 34 lateral low view of the floor placed on the trolley, the floor in wood (ref. 73) with its particular form. The ref. "73c" shows the circular machining and the ref. "73a" the external radius of siding. The ref. 114 shows the screws for the external fixing and with the ref. 115 the "special" carpentery for external fixing.
The ref. I l l shows the internal rails are placed in the internal profiles with "c" form" welded on the frame, while they are fixed with a support that it's bolted with wood screws at the floor (ref. 73).
Between the trolleys bearing the apple tables (fig. 25) are placed the trolleys without apple- table (fig. 35).
The trolley is assembled with a carpentry structure (fig. 35 ref. 117) at its side are placed two sliding blocks for taking the force of the advance motion (fig. 35 ref. 117a and 117b).
The floor is leaning on the APSOvib rubber metal rails (fig. 34 ref. 112) and it can be realized in any material, but it must have a capacity of loading by regulations.
The frames of the trolleys are placed beside one another. The contacts area has a circular form where they are placed the roller bearings (fig. 35 ref. 78) to avoid the crawling when the trolleys are placed beside.
To avoid the passage of dirty in the below area on the circular extremity are made some machining with tooth form. It allows to place side by side one another of the floors without the crawling because there is some millimetre of space.
The loads are acting on the trolley due at the weight of the persons, in the first stage are loaded on the pneumatic beams (fig. 42 ref. 140 and 141) until a 12 mm of compression after it's applied on the wheels without offset applied under the frame. This system allows to limit the flexion of the structure.
Between the carpentry structure and the pivot wheel is positioned the shock-absorbed plate (fig. 36 ref. 118), it allows a better distribution of the weight on the wheel.
In order to ensure a compression of the tyres of 12 mm are placed the guide rails over the tyres beams over there is acting the roller bearing (fig. 35 ref. 76). The roller bearings are adjustable with eccentric pivot. This system allows kept constant the plan of the floor also if there is a variable loading acting on it. With this system, the forces exercised by pneumatic beams are invariable. Without the guide rail, the level of the floor is proportional at the weight acting on it.
Figure 35 show a view by low towards upper of the components of the trolley.
The floor (ref. 116) is placed on the frame (ref. 117) of the trolley where the people can walk. On the frame (ref. 117) is welded the knurled blocks for power taking the motion, they have the ref. "117a" and "117b". The frame leans on the pivot wheels (ref. 74) at their side there are the iron plates for checking the maximum rotation (ref. 87).
On the externals of the frame (ref. 117) are placed the roller bearings (ref. 78) placed on eccentric pivot, it serves to ensure the approach beside one another without the crawling reciprocal.
The roller bearings positioned laterally at the frame (ref. 76 and 77) have the function of exercised the force on the upper rail to assure a compression of the tyres (fig. 42 with ref. pos. 140 e 141) on the knurled blocks for motion. The roller bearings (ref. 76 and 77) are adjustable with eccentric pivot, in normal situation there is 12 mm of compression.
In the middle of the frame is placed a device (ref. 119) on the plate (ref. 117c) for centering the floor (ref. 116) and it serves to prevent that traversal forces move the floor. Under the plate (ref. 117c) are bolted the extendable arms for linking the trolleys (fig. 39 ref. 123).
Figure 36 is the view of the section of the trolley. The floor (ref. 116) is placed on the frame of the trolley (ref. 117), under it a central plate is welded (ref. "117c"). At this plate (ref. 117c) are bolted the extendable arms for linking the trolleys (fig. 39 ref. 123). Over the plate (ref. 117c) is placed the device for taking the traversal forces (ref. 121).
Under the floor (ref. 116) is fixed to the wood with screws the plate in nylon or in plastic material (ref. 120), it carries the pin (ref. 122) that it's insert in the plate (ref. 121).
The frame of the floor is leaning on the pivot wheels with central axe and without off-set (ref. 74) at their side there are the iron sheet for containing the maximum rotation (ref. 87). Between the wheel and the frame is placed the synthetic plate for taking the vibrations realized in Apsopur (ref. 118).
Figure 37 shows the details of the wheel (ref. 74) and of the roller bearings with eccentric pivot (ref. 78). The eccentric pivot is placed in the frame (ref. 117 or fig. 27 ref. 83). The roller bearings (ref. 78) leaned at the sheet iron welded on the frame avoids the crawling with the trolley placed beside.
The extendable arms (fig. 39, 40 ref. 123) for linking the trolleys have the function to assure a correct functioning of the system it's necessary to joining the trolleys (fig. 39 ref. 71 and 72) during the tracks in curve and in rectilinear.
The distance between the articulation points of the extendable arms for linking the trolleys has value different during the rectilinear course and curve course. For this reason, it's necessary to development a system that it applies a minimum retain in rectilinear track and it can lengthen during the curve track.
The extendable arms (fig. 40) linking the trolleys, they are assembled by two parts. Every part is screwed on rod ends (fig. 40 ref. 126) with an articulated joint spherical that it allows the rotation. The rod ends are inserted in the pivots (fig. 40 ref. 125), that they are bolted on plates (fig. 35 ref. 117c) and/or on plate (fig. 27 ref. 83c).
The elongation requests an increasing extension force that increases the traction force between the trolleys. The increase of the traction force is due at the compression of the spring (fig. 41 ref. 129), during the increase the distance between the attacks point. The retaining force is variable between 80 N in rectilinear tracks and 280 N in curve tracks.
The increase of the traction force between the trolleys doesn't increase the frictional because the structures of the trolleys are leaning frontally on the rollers at bearing, (fig. n°35 and 27 ref. 78).
Figure 38 shows the composition of the trolleys in curve track with upper view made with alternative applications of a trolley with apple table (ref. 71) complete of the rotation system and two trolleys without apple tables (ref. 72), it has the function to distance the trolley with apple-tables for assuring a minimum distance.
Figure 39 shows the assembly of the trolleys explained in the previous figure with low view. It can see the collocation of extendable arms for linking the trolleys (ref. 123).
Figure 40 extendable arms (fig. 39 ref. 123) for linking the trolleys composed by a shaft (ref. 127) that it has the function of lengthen and compress the spring (fig. 41 ref. 129) placed inside the body where it scrolls (ref. 128).
At the end of the extremity of the rod (ref. 127) and of the body (ref. 128) are bolted the ends with an articulated joint spherical (ref. 126). They are inserted in the pivots (ref. 125), the pivots are screwed on the plates (fig. 27 ref. 83c and/or fig. 35 and 36 ref. 117c) of the frame trolleys.
Figure 41 shows a section of extendable arm for linking the trolleys where it can be seen the springs (ref. 129) inside the body (ref. 128), it is compressed by the rod of scrolling (ref. 127). In the drawing it can see the two lenghts of the spring (ref. 129). When the spring is all stretched out the trolley is in rectilinear course when the spring is all shorten the trolley is in curve course. The tyres beams have the function to transmitting the advance motion, they are composed by two external independent tyres beams (fig. 42 ref. 140) and two internal independent tyres beams (fig. 42 ref. 141).
The ring of traction is defined like "the external tyres beams", it's composed by two half rings (fig. 43 ref. 142) shown in figure n°45 composed by:
- A rectilinear course with the tyres are carried in rotation by engine that it is connected at cinematic chain for transmitting the moving force (figure n°45 ref. n° 145, 147, 148). - A curve course where the tyres have the function to support the trolley by means of knurled blocks (figure n°45 ref. 149, 150, 151).
Figure 42 shows the assembly of tyres beams for moving the trolleys. It's assembled by two rings, an internal ring and an external ring.
The ref. 140 shows the external tyres beams with engine positioned in sound-proofed cabinet.
The ref. 141 shows the internal tyres beams with engine positioned in sound-proofed cabinet.
Figure 43 there is the assembly for moving the trolleys, it's composed by two rings, one it's inside and the other one outside.
The ring of external tyres beams is composed by two tyres beams (ref. 142) with engine. Two independent engines groups (fig. 44 ref. 146) bring in rotation two rectilinear tyres beams, the engines are synchronized by a control of rotation made with encoder, in case there isn't the synchronize the number of rotations it can be changed varying the electricity supply or acts the brakes on the engines. The tyres (fig. 45 ref. 150) placed in the curve course have the function allows the support of the trolleys.
The ring of internal tyres beams is composed by two tyres beams (ref. 143) everyone with its engine (fig. 51 ref. 163). For reducing the length of the cinematic chain of the cogwheel are been made two independent tyres beams. The engines are synchronized by a control of rotations made by encoder, in case there isn't the synchronization of the number of rotations it can be changed by varying the electricity supply or acts the brakes on the engines.
The vertical guide rails (ref. 144) serve for power take-off for the rotation of the apple- table, under, they are placed the two power supply rails. Figure 44 shows the esternal ring complete, where we can see the tyres with beams that is composed by two half-ring ( ref. 142) everyone with a engine groups (ref. 146) that during the normal functional it's covered with sound-proofed cabinet (fig. 49).
Figure 45 shows half beams tyres that it's composed the motorized ring external.
The engine groups with sound-proofed cabinet (ref. 145), it supplies the power for moving the tyres beams ( ref. 147).
The power force of the tyres beams is assured if the deformation of the tyres is made acting the roller bearings (fig. 27 and 35 ref. 76 and 77) on the upper rails (ref. 148). The roller bearings (fig. 27 and 35 ref. 76 and 77) are placed at side of the trolley frame (fig. 27 ref. 83 and fig. 35 ref. 117).
The tyres with free rotation (ref. 150) have the function of supports the trolley frame by mean of knurled blocks placed at the side of trolley. The tyres are placed on the frame of the curve external at an lower level respect at the tyres beams. The upper guide rails in curve (ref. 151) has a function to maintain at the same height the floor of the trolleys, because during the curve course there isn't the compression of the tyres, it could verify an raising of the floor of the trolleys.
Figure 46 is the details of the external tyres beams.
The engine groups (ref. 145) is covered with sound-proofed cabinet. It supplies the force for rotations of the tyres beams (ref. 153). The tyres beams are composed by cinematic chain where are placed an engine tyres (ref. 145) with a cog-wheel that it receives the force of motion from pinion placed on the reduction gear or from returned group (ref. 154) that is interposed between every tyres groups.
The frame ( ref. 155) is the supports of the tyres group, while the curve course frame ( ref. 149) is placed at a lower level allowing a function with the tyres (ref. 150) of leaned of the knurled blocks placed at side of the frame trolley. Both frames leans on the cushioning (presser foot) device with anti-tear safety device (ref.152). On the tyres groups are positioned the guides rails (ref. 148 and 151).
Figure 47 is another detail of the external tyres beams with view from inside. The ref. "A" indicates the joining beetwen the rectilinear frame (ref. 148 and 155) and curve frame (ref. 149 and 151).
Figure 48 shows the alone structure of the beams bringing the tyres beams where you can see the curve frame (ref. 149) that it's joined to the rectilinear frame (ref. 155), the joint is identifies with reference "A". It permits an adjusting parallel to the cement floor. The 2 - structure is composed by two frames are leaning on the presser foots dampening with anti- tear safety device (ref.152) for absorbing the vibration. Under every presser foot there is an iron sheet, with its removing or changed the thickness it is possible the adjustable for every presser foot for compensating every irregularity of the cement floor.
Figure 49 is the representation of the engine group of the tyres beams complete of the sound-proofed cabinet.
The engine tyres (ref. 153) engages the pinion of the gears box covered by sound-proofed cabinet (ref. 156), it's ventilated with fan (ref. 157) to change with fresh air. The rotation speed is variable in case is necessary for increase of the temperature.
Figure 50 is the view of the engine group of the tyres beams.
The frame (ref. 161) supports the tyres group (ref. 153) and the gears box (ref. 158). They are leaning on cushions (pressers foot) with anti-tear safety device (ref.152). The cushions are adjustable changing the thickness of the below iron sheet.
The gears box group (ref. 158) is shown without sound-proofed cabinet and fan for ventilating of engine. The engine applied is complete with encoder for checking the rotations and parking brake, it's activated in emergency case.
The drive tyres act on the knurled blocks (fig. 27 ref. 83a or fig. 35 ref. 117a) placed at side of the frame trolley, they are placed on supports with bearing. They receive the rotation by mean of cog-wheel (ref. 159) meshes on the pinion assembles on the shaft of the gearbox (ref. 160).
The second ring for traction is defined like "internal tyres beams", it's assembled with two identical half ring shown in figure n°52 with an engine group shown in figure n°56 placed between the rectilinear tyres beam and the curve tyres beam.
The rectilinear beam receives the motion of engine group and the motion force is transmitted by means of cinematic chain (fig. 53 ref. 159) at every tire group (fig. 53 ref. 153, 154). The advance force is given by the action of the tyres on knurled blocks (fig. 27 ref. 83b o fig. 35 ref. 117b) placed at side of the frame trolley.
The curve beams receive the motion of engine group (fig. 53 ref. 164) through a reduction made with cog-wheels (fig. 53 ref. 173, 174, 175, 176) and it is transmitted by mean of cinematic chain (fig. n°53 ref. n°169 and 182).
Every internal tyres beams is continuous and every tyres group (fig. 53 ref. 153 and 169) is equipped with toothed pinion. Tyres groups receive and transmitted the motion through the cog-wheel. It meshes with pinion placed on shaft of gear box or on cog-wheel placed on shaft free of rotation placed in the support with bearings (fig. 53 ref. 154 or 182).
To avoid cinematic chains too much long is being built with two independent tyres beams (fig. 52 ref. 143) placed on the same ring (figure n°52). Every tyres beam has an independent engine group (fig. 52 or 53 ref. 164). The engines are synchronized with encoder group. If it's necessary, it is possible to vary the rotation speed changing the tension of power supply or act the service brake placed on the engine.
The engine is placed between the rectilinear beam and the curve beam for reducing the solicitations on every first pinion of tyres beam (fig. 53 ref.159 and 175).
The structure of the tyres beams leans on on cushions (pressers foot) with anti-tear safety device (fig. 53 ref. 152).
On the tyres beam for assure an equal compression of the tyres of 12 mm are placed the guide rails (fig. 53 ref. 171 and 172). The roller bearing (fig. 35 and 27 ref. 77) is placed on eccentric pivot acts on the upper rails for maintaining constant the level of the floor placed on the trolleys also if there is a variability of the loaded applied. The force is exercised by tyres is constant because there isn't variability of the compression of the tyres otherwise it's proportional at the height of compression of the tyres.
Outside of the tyres beams are placed the vertical guide rails (fig. 59) they serve to transmitted the motion for rotation of the apple table positioned on trolley. Their supports lean on the insulating sheets (fig. 58 ref. 190 and 193) with thickness of 12 mm, they have the function to muffle the vibration.
Under the vertical guide rails are placed the rails for taking the direct current (fig. 59 ref. 194, 195, 197, 196), they are composed with an iron sheet with shape "c" and two copper profiles for transport of the two phases of the current placed on plates insulating (fig. 59 ref. 162 and 166). The iron sheet with shape "c" has the function to protect the two electric lines to avoid the dispersion of sparks.
Figure 51 shows the internal ring composed by two tyres beams with independent engines, the gear box with engine are covered by sound-proofed cabinet with fan.
The two tyres beams (ref.143) with independent engine (ref. 163) at the external side is placed the vertical guide rails (ref. 144) for taking the motion for the rotation of apple- table. Below vertical guide rails there is rails for taking the direct current.
The upper rails (ref. 168) has the function to assure the compression of tyres and maintain the same height of the floors of the trolleys. Figure 52 shows the components of half ring of tyres beams everyone with independent engine, the engine group is shown without sound-proofed cabinet and fan.
Figure 53 is a detail of the groups tyres beam where you can see the system for transmitted the rotation force from gear boxes with engine (ref. 164) at the rectilinear tyres beam and at the curve tyres beam.
The rectilinear beam for transmission of the motion is made with the tyre group (fig. 53 ref. 179). The tyre group is completed of pinion (ref. 153) and pneumatic. In the tyres beam between every tyres group is interposed a return group (ref. 154). Both their shafts are supported by bearings place in the support. The first tyre group its cog-wheel (ref. 159) is assembled on the same axe of the low speed shaft end out by gear box (ref. 173).
The gear box with engine (ref. 164) independently cooled it is positioned in a soundproofed cabinet with fan. The engine is completed with encoder groups, brake motors with d.c. brake. On the low speed shaft end in exit is placed the pinion (ref. 173), it transmits the rotation at the cog-wheel (ref. 175) for reducing the rotation speed for tyres beams curve in proportion at the radius of curve of the course the conveyor. On the same shaft of the cog-wheel (ref. 175) is placed the conic cog wheel (ref. 176), it transmits the rotation at the conic pinion (ref. 174) placed on the extension of the shaft of tyres group (ref. 169). It is located at the beginning of the tyres curve beams and the shaft is placed on support with conic pinion (ref. 174), it transmits the rotational motion at another conic cog-wheel (ref. 170), it's meshed with at the return group (ref. 182) that it's free to rotate because it's place on the support with bearings.
The upper rails curve (ref. 171) and rectilinear (ref. 172) on they are acting the roller bearing placed at side of the trolleys (fig. 27 and 35 ref. 77) that it has the function to assure the compression of the tyres on the knurled block. The ref. "A" put in evidence the meeting point between rectilinear and curve rails.
The vertical guide rails are placed at the external tyres beams for taking force to make the rotation of apple table. They are composed by a curve course (ref. 188) and a rectilinear course (ref. 191).
The ref. 180 of the figure indicates the spacer arm for positioning the vertical guides (ref. 188 and 191) from the internal tyres beams.
All frames are leaned on cushion (pressers foot) with anti-tear safety device (ref. 152) below of it, it's positioned an iron sheet for levelling of the tyres beams. Figure 54 is an external isometric view of the engine of tyres beams where you can see the references shown in figure n°53.
The vertical guide rails are composed by curve course (ref. 188) and rectilinear course (ref. 191) for taking out the rotation force of the apple table by mean of tyre group placed on the trolley (fig. 27 ref. 75). Below vertical guide rails are placed the two rails for taking the direct current (ref. 167). The supports of the rails are fixed with the bolts at expansion or chemical (ref. 184).
The reference "A" of the figure shown the joining between the rectilinear and curve guides. The reference "B" shown the joining between the two rectilinear rails.
Figure 55 is an assembly of view internal beams where are shown the same references of figure n°53. In particular, you can see the collocation of the gear box with engine (ref. 164(163)) inside of sound-proofed cabinet with fan (ref. 183).
Figure 56 is a details of engine group of the tyres beams. The tyre group (ref. 179) with the pinion (ref. 159), is placed on the same axe of the low speed shaft end exit of gear box from is taking the force (ref. 183(163). On the same shaft is placed the cog wheel (ref. 173) that it transmits the rotation force to the cog-wheel (ref. 175). The cog-wheel (ref. 175) reduces the rotation for adapting at the rotation speed of the tyres in curve secondly the geometry of the conveyor. The shaft carries the cog-wheel (ref. 175) and it is supported by two supports (ref. 185) for bringing in rotation the conic pinion (ref. 176). This it is coupled with conic pinion (fig. 55 ref. 174) placed on the shaft of the first tyre group of the curve beam.
The frame (ref. 186) carries the reduction gear box with engine placed in sound-proofed cabinet with fan (ref. 183). They transmit the rotation at both the shafts of the tyres group in curve or in rectilinear course. The frame (ref. 186) is leaned on cushion (pressers foot) with anti-tear safety device (ref. 152) below of it, it's positioned an iron sheet if its thickness is varied for levelling it.
The ref. 180 of the figure indicates the spacer arm for positioning the vertical guides (fig. 55 ref. 188 and 191) from the internal tyres beams.
Figure 57 is the details of engine group with tyre without to show the sound-proofed cabinet with fan (fig. 56 ref. 183). The figure shows the rotation of the gear box with engine (ref. 187), it supplies the power for rotation at the tyres beam in curve and rectilinear strokes. The elements interact secondly the description of figure n°56. The engine (ref. 187) independently cooled of the gear box it has an encoder group for checking rotation and brakes motors with direct current.
The safety devices for checking engines (fig. 57 ref. 187) of the right-angle shaft reducers with motor chosen for this application are equipped of:
- Brake motor with direct current is acting on the engine. It can use for emergency stopping the system of advance or to synchronize the motor when there are a lot numbers of rotation different between them.
- The encoder group for synchronizing the engines are applied in the tyres beams.
- Lever for releasing the brake motor.
- Engine with independently cooled, this function is necessary because the gearbox with engine is placed below of the floor of the trolleys inside the sound-proofed cabinet.
- To assure the number of re-changes with fresh air inside the sound-proofed cabinet where is placed the fan (fig. 55 and 49 ref. 157) connected to a thermostat. The thermostat changes the number of rotations of the fan (at according to the difference between temperature detected and the advice temperature to avoid the overheating.
The system of rotation of the apple-table, illustrated in this system, it allows at the apple table placed on the conveyor composed by trolleys to advance the apple table while it rotates on itself.
The system of rotation of the "apple-table" is composed by two parts:
- The first part is the taking of rotation on the trolley by means of a tyre (fig. 27 ref. 75).
The motion force is transmitted with the chain (fig. 27 ref. 80) at the device of rotation of apple-table.
- The second part is the vertical driving rails (fig. 59 ref. 188 and 191) on it acts the tyre roll group (fig. 31 or fig. 27 ref. 75).
The system of rotation could not be applied, it's a request of the customer. The apple-table can be positioned fixed on the trolley.
The vertical driving rails (fig. 59 ref. 191 and 188) on it makes action the tyre (fig. 27 ref. 75), it is placed at the external of the motorized tyres beams. The system is brought by vertical supports welded on the base (fig. 58 ref. 189 and 192) plugged on the floor in cls, between the iron base and the cement floor is placed a sheet in Asopur of the Angst-Pfister for insulating by vibration (fig. 58 ref. 190 and 193) could be create during the motion of the trolleys. On the support (fig. 58 ref 189 and 192) is fixed a vertical driving rails where the knurled vertical rails (fig. 59 ref. 188, 191) allow to take the rotation force by means a compression between 12 and 15 mm of the horizontal tyre.
Inside the vertical driving rails (fig. 58 ref. 188 and 191) there is a smooth surface where the roller bearing placed on the eccentric pivot (fig. 27 ref. 81) exercise a force. The eccentric of the pivot allows the adjusting of the compression of the tyres. The value of compression is kept constant during the curve and rectilinear course.
The rails for taking the power supply are composed by an iron sheet with shape at "c" (fig. 59 ref. 194 and 195) inside there are placed two insulated (fig. 59 ref. 162 and 166) rails in cupper (fig. 59 ref. 196 and 197). Every rail carries a phase over it acts the arm for taking the current placed on the trolley, (fig. 27 ref. 79).
Between the vertical driving rail and the rail for taking current there is an extinguish group (fig. 59 and 60 ref. 198), it is composed by a pipe fixed on the vertical support (fig. 58 and 59 ref. 189, 192). On the pipe, there are the splinker, some turned towards where the trolleys pass (fig. 61 ref. 201) and other turned toward the internal of the tyres beams (fig. 61 ref. 200) where there is the mezzanine for the apples tables centrals.
Figure 58 shows the assembly of external driving rails of the tyres beams. They are composed by rails for taking force for rotation of apple-table (ref. 188, 191), the box in plates for contain the rails for electricity supply (ref. 194, 195) and the extinguishing group (ref. 198).
The bases curve (ref. 189) and rectilinear (ref. 192) are built whit a profile in iron welded on base. They are plugged on cement floor (ref. 184), an insulating sheet (ref. 190 and 193) in Apso-Pur of Angst-Pfister is placed between the cement floor and the iron base.
Figure 59 shows the assembly with external view of the internal rails of the tyres beams. The bases curves (ref. 189) and rectilinear (ref. 192) bring the three groups.
•The groups for taking the rotation in curve, that are composed by metal sheet curved (ref. 188) has a side knurled and by opposite site there are the plates for the horizontal fixing with buttonhole on curve base (ref. 189) and rectilinear rails (ref. 191) placed with grub screw. Both they have a knurled part where the horizontal tyre takes the motion (fig. 27 ref. 75). The tyre has a constant compression during the path, the compression is assured by roller with bearing (fig. 27 ref. 81) that it scrolls on the internal smooth part. •The rails in cupper for taking the electricity supply (ref. 197 and 196) are placed inside the supporting structure (ref. 194 and 195). The rails are placed on insulating sheet (ref. 162 and 166).
•The extinguish group (ref. 198) with some splinker oriented towards centre where is the mezzanine and someone towards the trolleys.
The rotational motion is transmitting by mean of a chain (fig. 27 ref. 80) at a crown wheel placed on clutch (fig. 27 ref. 85), the clutch must have electricity supply for doesn't transmit the engine force.
The clutch (fig. 30) is activated in the follow case:
- When the persons go up and go down from apple-table.
- For disabled person for place the platforms for bring them.
- If the platform is positioning and the pivot plate hooks at the electric magneto. After the positioning, in case falls down to will or to assure of the customer, the pivot late acts proximity sensor (fig. 20 and 22 ref. 61) placed under the platform.
- In the eventuality, the customer doesn't want the rotation during the service.
If the clutch is closed, the motion is transmitted at the pinion, it's meshed at the cog-wheel positioned concentric at the apple-table (fig. 27 ref. 84) with screws and pivots on bring shaft for transmitting the rotation at the apple-table.
For safety in this closed system with presence of inflammable material like tyres and the wood floor of the trolleys, they generate a light fire load. It's necessary place a fire prevention system with splinkers. The fire prevention system is placed between the vertical driving rails and the rails for taking the current (fig. 60 ref. 198). The sprinkling of the splinker covers the zone under the conveyor belt (fig. 62 ref. 201) and the area under the intermediate floor where are placed the central apple (fig. 62 ref. 202). Because the ring of extinguish has the splinker turned towards both sides.
Another extinguish ring (fig. 60 ref. 199) is placed between the external walls of the course of the conveyor belt and the tyres beams with the splinker toward the conveyor belt (fig. 63 ref. 204) because the breadth of the conveyor belt is very wide.
Figure 60 shows the positions of two extinguish rings under the walking floor:
The internal extinguish ring (ref. 198) is placed over the rails of power supply.
The external extinguish ring (ref. 199) is placed between the walls of the conveyor course and the tyres beams. Figure 61 is the detail of the internal extinguish ring, where you can see the pipe carries the extinguish material (ref. 202), it's placed over the rail for taking current. It has the splincker toward the internal side (ref. 200) where there is the mezzanine with the apple tables and other splicker toward external side (ref. 201) where there are the trolleys of the conveyor belt.
Figure 62 is the internal extinguish ring, it is shown for half course because it's symmetric. It can see the dislocation of the internal extinguish ring (ref. 202) placed between vertical driving and the rails for taking power supply with the splincker toward the inside mezzanine (ref. 200) and the splincker toward the conveyor (ref. 201).
Figure 63 is the upper view of the two extinguish rings (ref. 202 and 203).
The system is managed by control device (fig. 69 ref. 220) unit placed on the mezzanine frame under the floor in the central apples with autonomous rotation. The control unit manages the acceleration and deceleration of all engines.
Every gear box with engine (fig. 44 ref. 146 and fig. 51 ref. 163) have an encoder group placed on the engine. The synchronization is made with two manners based on the numbers of rotation of the engine. It's made with checked the number of rotation in absolute way establishing a minimum error range and checked in incremental way, the control unit counts the number of rotation of every engine from when it starts to rotate.
The gear boxes are equipped with brake motors. The verification of the number of rotation of the engine serves for checking the different speed of rotation. If the control unit verifies a different number of rotations between the engines, it can correct the speed of rotation changed the value of alternating current managed by the inverter. In case of excessive of rotation difference, the unit control can use the brake placed on every engine.
Near at every corner of the room are placed the buttons for starting, stopping the rotation of the conveyor belt and a button for emergency stopping. Their position is identified in figure n° 5, 6, 7, 8 with ref. "la".
In case the employees make a maintenance are placed some safety device. If a person has access to the electrical equipment indicated in fig.65 with reference n°220 or if someone remove some floors of the mezzanine area placed in the middle of the conveyor, the proximity switches notices the removal. If there is a signal from proximity switch the moving of the conveyor belt is stopped.
The safety interrupts coded with magnetic system XCSDM Schneider are indicated in fig. 65 with ref. n° 217 a, b, c, d, e, f, g. At the tyres beams place under the conveyor belt is impossible to access without stopping the conveyor. The access is possible after to remove the lateral rails placed lateral at conveyor (fig. 5 ref. 11) and some part of the mezzanine floor that are watched by safety switches coded with magnetic system XCSDM Schneider.
The monitoring system is based on the function of safety stopping operated by a mobile protection, it protects the access to dangerous area.
The stopping controls with maintaining the power supply to the activation to allow the reaching of the stopping and then the interruption of the power supply in the actuator.
The dangerous movement is stopped by emergency button (fig. 5,6,7,8 ref. la) and by the device for emergency stopping.
The opening of the mobile protection is detectable with safety switches (fig. 65 ref. 217 a, b, c, d, e, f, g). It starts the stop functional on ramp of braking and with acts of the brake placed on engine with interrupted of power supply of engine at the tyres beams (fig. 44 ref. 146) also at the engine (fig. 53 ref. 164 or fig. 51 ref. 163) and the engines of the central apples with autonomous rotation (fig. 65 ref. 218, 219).
When the checked timing is expired, the safety modules are disabled the timer safety exit. The drive is stopped with the function STO (Safe Torque Off) integrated, with it is prevention of the accidental restart of the engine.
The safety switches coded with magnetic system XCSDM Schneider indicated in fig. 65 with reference n°217c and 217e or in fig. 67 ref. 230a and 230b, are placed over the electric station must forecast the timing of the closing to allow the closing of the manhole after the reactivation the electric station but before the departure of the conveyor gave by button for start and stop conveyor (identified in fig. 5, 6, 7, 8 with ref. "la") placed near at every corner of the dining room.
Figure 64 shows the functioning scheme of working proposed by Schneider for the management of engine inserted in protected area with safety switches coded with magnetic system XCSDM Schneider.
Figure 65 shows the dislocation of the safety switches coded with magnetic (ref. 217) and the electric station (ref. 220).
If the floor placed on the mezzanine placed in the centre of the conveyor (ref. 214) is removed the safety switch coded (ref. 217a and ref. 217g) signalled it. Rather in case the removed of the floor placed in the middle of the mezzanine of the conveyor (ref. 215) the safety switch coded (ref. 217d and 217f) reports it. If the floor (ref. 216) is removed by the structures placed in middle of the apple, the safety switch coded (ref. 217b) reports it.
If the manholes over the electric stations are opened (ref. 220) the safety switches coded (ref. 217c and ref. 217e) reports it.
Figure n°66 is the detail of the installation of the safety switches coded placed on the floor (ref. 215 and 214), in these pictures are shown the similar cases, the first figure reproduces ref. 215 of the fig. 65 with switch ref. 217d and 217f. The second and the third figure shows the ref. 214 of the fig. 65 with switch ref. 217a and ref. 217g.
The safety switches coded with magnetic system XCSDM is identified with ref. 230 and it's placed on the frame ref. 222 or 224.
The magnetics (ref. 231) are bolted on the plate (ref. 229). It's fixed on the floor (ref. 215 or 214).
Figure 67 is the structure placed between the central apple table and the apple table located in the centre of the radius the conveyor. It carries the electrics switchboards (fig. 65 ref. 220), on the floor (fig. 65 ref. 216) there are located the safety switches coded.
The three safety switches coded with magnetic system have those functions:
•The safety switch coded with ref. 230a and 230b, are attached to the frame of the manholes and the magnetic part (231a, 231b) are placed on the manholes by mean of the plate (ref. 229). They check the opening of the manholes to enter to electrical switchboards (fig. 65 ref. 220), when it opens the power supply is removed. The departures of the engine are made after the close the manholes.
•The safety switch coded (ref. 230c) is fixed on the frame of the mezzanine (ref. 223) and the magneto is connected (ref. 231c) to the floor (ref. 216) to signal if it is removed from the frame (ref. 223).
In addition, at this safety system is applied the fire prevention system described in the previous chapter.
The description of the rotation system of the central apple-table is illustrated in Figure 68 is shown together with the view of the supporting structure of the central apple with autonomous rotation placed inside the conveyor belt. It's composed by three apple table for six persons. Two apples tables (fig. 68 ref. 211) are located in the centre of the radius of the conveyor and one is placed in the middle of the structure (fig. 68 ref. 212). Between the apple (fig. 68 ref. 211) and the apple (fig. 68 ref. 212) on both side is placed the bearing frame (fig. 68 ref. 213) under of its floor are placed the electrical switchboards (fig. 69 ref. 220) for manage of the conveyor and the rotation of the apples tables.
Figure 69 is the lateral view. The description is same as the previous. Under the walking floor there are the electrical switchboards (ref. 220) for management of the all engine and the safety.
Figure 70 is the toghether view under the walking floor of the supporting structures where they are placed the apples tables with indipendent rotation placed inside the conveyor. It's composed by frames (ref. 222) for two apples tables for six persons (fig.68 ref. 211) are placed inside the curve of the conveyor and the frame (ref. 224) is placed inside the apple table for 6 persons in the middle of structure (fig. 68 ref. 212) inside the conveyor. Between the frames (ref. 222 and 224) of the apples tables are placed the mezzanine frame (ref. 223). Under they are placed the electrical switchboards for management of all system (ref. 220).
In the middle of the frames with ref. 222 and 224 there are the rotation groups (ref. 225) of the apple table. It is possible to see the central shaft placed with roller bearing. They are placed in the middle of the rotation track of fixed wheels, they bring the weight of the apple table. Every rotation groups (ref. 225) have a gear motor box (ref. 218 e 219) placed inside the sound-proofed cabinet with fan. Every engine has the encoder group and brake. On the frame (ref. 222, 223 e 224) are welded the irons bended with shape at "c" inside are located the APSOvib rubber metal rails of Angst-Pfister (ref. 228) fixed to the floor. On the frame (ref. 224) is applied the device for remove the transversal forces (ref. 227), they can be generated by the persons walking on the upper floors.
The apples tables of rotations on itself place in the internal space of the conveyor have the assemble similar at the systems applied on the trolleys, the main components are:
- A gear motor box group (fig. 72 ref. 234 and fig. 78 ref. 218) transmits the rotation force at a pinion applied on the shaft, the pinion meshes on a big cog-wheel (fig. 72 and 78 ref. 225) collocates concentric at the shaft. The apple tables are bolted with screw and pivot on the upper shaft (fig. 75 and 80 ref. 86) for bringing in rotation.
- In this solution, the clutch is not used because there is a gear motor box for every apple table. If it's necessary to stop the rotation, it's need to take away the current at every engine and or it's possible act the brake on the engine.
The case when it is necessary to stop the rotation: - When the persons go up and go down from apple-table.
- For disabled person for place the platforms for bring them.
- If the platform is positioning and the pivot plate hooks at the electric magneto. After the positioning, in case falls down to will or to assure of the customer, the pivot late acts proximity sensor (fig. 20 ref. 61) placed under the platform.
- In the eventuality, the customer doesn't want the rotation during the service.
The rotation system is composed by cog-wheel (fig.75 ref. 84), it takes the rotation by the pinion (fig. 75 ref. 226) places on the exit shaft by gear motor box (fig. 75 ref. 234).

Description of the cupboard carries the dishes.
In this restaurant are placed n°13 apple-table. Every apple-table can contain between 6 or 8 persons. It's necessary to have a cupboard to place the ready dishes before they are serving. Especially, in this type of room, where the table in some time is nearest and in other time is far. This cupboard is located between the dining room and the kitchen.
This system is based on the principle to leave at the customer the possibility to order in every moment. The order is transmitted in the same time at the kitchen for preparing the foods and at the service area for preparing the drinks. After the drinks are prepared, the waiters are to knowledge of the table has made the order and they can make the delivery.
When the chef finished the preparation of the dishes, it needs a place for depositing the dishes, to avoid accumulation. For this reason, it was created this cupboard for managing the dishes from the kitchen waiting the delivery at the tables of the dining room. In this cupboard are reserved two floors for every table, in this way it is possible to reserve an identical place for every customer. This system reduces the communication between the chefs and the waiters.
In this specific case, it can be useful to make a cupboard for the equal tables and another for odd tables, this system allows to have more time for every waiter for taking and deliver the ready dishes at the customers.
Figure 99 is a frontal view of the cupboard (ref. 250) carries the dishes. In this view is possible to see the appearance of it (side kitchen).
The main function is stored ready dishes by chef in the kitchen, with a characteristic to maintain in temperature the dishes before they are served at the table.
Figure 100 is an isometric view by kitchen side of the cupboard without the lateral protections.
The push buttons (ref. 251) serve for calling the plane of the number of the table. The position of the push buttons can variable. They have the function to activate the gear box engine placed in sound-proofed cabinet with fan (ref. 265). The gear box engine has two exit shafts for activing two chains (ref. 260) by means of two crown wheels mortised on every exit shafts, every chains (ref. 260) is kept in tension with tightener (ref. 261). Every chain carries in rotation an lower group of the main chain (ref. 264) for supporting the loading trays of the ready dishes.
The rotation can be disconnected by the micro (ref. 254) when it reads the iron reference (fig. 105 ref. 274) placed on the cover in plexiglass (fig. 105 ref. 253) during the charging or the storage of the dishes. The cover in plexiglass is realized with special materials to allow the passage of the radiations of sterilized with special sterilization light (ref. 255) to destroy the bacteriums. The magnetron device (ref. 252) is for heating the food.
All components of trasmitting are protected with the protection of the second shaft (ref. 266) and also the lateral components (ref. 267).
In this case, it is used a cupboard with two differents levels of loaded because there is a difference between the walking floor in the kitchen and in the dining room (for the height of the conveyor group).
A particular of this cupboard is the rotation of the trays. The trays are kept in horizontal way, it's based on the geometric principle that for two axes is possible to make pass an only plane. To obtain this result, two chains are placed (fig. 104 ref. 264) with special attachments placed on the same plane but the axes are staggered of a distance this stagger is possible to see notice the inclination of the chain (fig. 104 ref. 260) joining at the shaft (fig. 104 ref. 270 in exit of the gear box engine ref. 269). Over the special attachments of the chain is placed a cube to bring an articulated joint (fig. 104 ref. 268). Every side of the articulated spherical joint determine an axe, the two chain are placed a wheelbase "1" for every plane is possible to determinate two axes.
With the synchronism of both chains, they perform the same course to keep the plane in horizontal way.
This synchronism is obtained with gear box engine with double shaft (fig. 104 ref. 269) the mechanical synchronism is always perfect, it doesn't request an electrical check. The installation of articulated spherical joint (fig. 104 ref. 268) corrects some misalignments that can be verified during the normal operation or due at the construction.
The gear box engine (fig. 104 ref. 269) with independently cooled is placed in sound-proofed cabinet (fig. 100 ref. 265). The electronic management is based on the push buttons placed at the lateral side (fig. 102 and fig. 103 ref. 251) where it's added the emergency button for stopping the rotation with the actioned of the brake placed on the gear box engine, if it's necessary. To every button is assigned a number of table, the chef in the kitchen calls the necessary tray for depositing the dishes. When the waiter receives the communication, he is placed at the opposite site of the side cupboard kitchen, he calls the necessary tray for taking the dishes to deliver at the table.
The lateral flags placed on every group of the trays near at the special attachment on the chain (fig. 102 ref. 258) permutation when the tray arrives in the correct position it actives the proximity switch (fig. 102 ref. 256 and 257) corresponding at the tray called. For obtain this, it's necessary to put a condition, that it's the proximity switches with lower numeration at the number of the apple table wished must be closed and the proximity switches with upper numeration at the number of the apple table wished must be open.
Other two proximity switches (fig. 102 and 103 ref. 254) are placed at the side of the path of the tray placed on the chain. These proximity switches have a function to signal if there is some cover open, they avoid the rotation of the system during the operation to put or take out the dishes.
If the push buttons (fig. 102 and 103 ref. 251) placed the opposite side of the operator, are activated, the rotation is disabled and the request is memorized.
The system is to contact with the food, for respected the sanitary norms and it's necessary sterilize the trays and the adjacent space. For sterilizing the internal of cupboard are placed some special lamps of OSRAM (fig. 102 and 103 ref. 255) to destroy the bacterium.
The lamp has a light with a wavelength of 254 nm necessary for the sterilization. In the cupboard are placed more lamps for have a distributing the light in uniform way, it's allow to avoid the shade zones because this area can allow to be established of bacterium. In the cupboard are inserted eight (or less number) lamps with a power of 18W.
All the trays are covered with plexiglass (fig. 105 ref. 253) type UVD or with Acrisun Plus Plexiglass GS UV, they are transmitted the 85% of the irradiation of the bacterium lamps. The foods are heated with the application of four (or less) Magnetron devices by 100 W of the Panasonic o similar (fig. 102 and 103 ref. 252). They produce the microwaves to heat the food, in alternative it's possible to heat with halogen lamp, they let out a light with a wavelength of 1100 nm by 500W.
If the Magnetron is installed are necessary some proximity switches for active or disable the emitter of microwaves "Magnetron" (fig. 102 and 103 ref. 252) when the tray (if it's in iron) pass in front of it, with any sense of rotation. The system is composed with two proximity switches (fig. 102 and 103 ref. 259). The first proximity switch-takes out the electricity supply at the Magnetron and the second reactivate the electricity supply. The proximity switches can't be applied if the trays are at zero potential energy with a connecting at ground or if the trays are built in plastic material insulating.
The "Magnetron" device is a generator of microwaves frequency. It works putting in movement the molecules rich of water, their movements heat the food during the passage in front of emitter. In this case, it isn't a necessary a high supply of heat at the food but it only a maintaining of the temperature. In the mobile are placed four elements, two for every side (fig. 102 and 103 ref. 252). One in the area for loading or unloading, and another placed along the way of the trays.
Figure 101 is the detail of the view of loading/unloading dishes.
The push buttons (ref. 251) serve for selected the number of the tray where places the dishes. In internal space of the cupboard is applied a Magnetron (ref. 252) for heating the food, it can be replaced with halogen lamps.
The covers (ref. 253) are realized in special Plexiglas, it allows the passages of the sterilized and heated microwaves. The cover is supported with springs at gas.
Figure 102 is the lateral view of the components applied.
The push buttons (ref. 251) for the selection of the table with at an emergency button. The fourth proximity interrupts (ref. 254) applied in the cupboard serves to read the iron references applied on Plexiglas cover (ref. 274 fig. 105). They have the function to interrupt the rotation of the tray and disconnect the magnetron (ref. 252) and/or the lamp for the sterilization (ref. 255).
Proximity switches (ref. 256) for stopping the rotation when the trays arrive in correct position in side dining room and the proximity switches (ref. 257) for stopping the rotation when the trays arrive in correct position inside the kitchen.
Plate of indicator the position of tray (ref. 258), on they are acting the proximity switches (ref. 256 or 257) for stopping the rotation when the tray is in correct position. The plates of indicator (ref. 258) are placed on the special attachment on the chain where the articulated joint spherical is placed (ref. 268 fig. 104).
The proximity switches (ref. 259) have the function to activate or disable the emitter of microwaves "Magnetron" (ref. 252). The first switch (ref. 259) takes out the electrical supply at the Magnetron and the second switch puts the electrical supply.
Transmission group of the motion force (ref. 260) by crown wheel mortised on the exit shaft by gear box and the chain is maintaining tensioned by means of the chain tensioner (ref. 261) for transmitting the force to the main chain (ref. 264).
Lower tensioner of the return group (ref. 262) of the main chain (ref. 264), it takes the rotation force by the transmission group of the rotation (ref. 260). It has a scrub screw for tensioning with the pinion (ref. 262) of the main chain.
Also, the upper tensioner of the return group (ref. 263) of the main chain (ref. 264). It has a scrub screw for tensioning of the pinion the main chain. The special chain with adaptors for bringing the cube blocks (fig. 104 ref. 268) are fixed on adaptors of the chain. In the threaded hole of the cube block is screwed the articulated joint spherical to bring the tray plane between the pivot (fig. 105 ref. 272).
Figure 103 is the lateral view by opposite side of the cupboard. The push buttons are indicated with ref. 251, they are placed on side of the kitchen.
In this figure, there are the same references described in previous figure (n°102) with the same function. The references n° 256, 257, 258 are not indicated in figure because they aren't installed by this side.
Figure 104 shows the moving system, it's composed with two main chains with special adaptors (ref. 264), the rotation is made with gear box engine with double shafts (ref. 269). The main chain n°l (ref. 264) with special adaptors, on they are placed the cubes for bringing the articulated joints sperical (ref. 268). The chain is supported by the upper tensioner group (ref. 263) and lower tensioner group (ref. 262), both with grub screw for tensioning the group. This system is placed by side of the gear box engine (ref. 269), it's takes the motion by the secondary chain that it takes the rotation force from crown wheel placed on the exit shaft of the gear box motor. The secondary chain is kept in tension with chain tensioner (fig. 102 and 103 ref. 261).
The main chain n°2 (ref. 264) is equal to the first main chain with special adapters bringing the cube blocks, on they are fixed the articulated joints sperical (ref. 268) brought of the trays. The main chain n°2 is placed by opposite side of the gear box engine (ref. 269). It takes the motion by the second exit of the gear box engine by mean of chain envelops on crown wheel placed at the end of a long shaft (ref. 270) with bearings support placed near at the crown wheel.
The gear box motor (ref. 269) is placed on the base of the cupboard, it's indipendently cooled. It has an group encoder for checking the numbers of rotation. It's placed in soundproofed cabinet with fan.
Figure 105 is the detail of the tray for bringing the dishes. It's composed by a tray to lean the dishes (ref. 271). The tray is realized in iron sheet or insulating plastic material. At their extremes are placed the pivots (ref. 272). The pivots are placed in articulated joints sperical, they are screwed on the blocks placed on adapters of the main chain (ref. 268 fig. 104).
On the tray (ref. 271) are placed the plexiglas (ref. 253), it can be open. It can be maintained open with the force of springs gas (ref. 273) placed on the sides. The 8 - plexiglass installed on the tray are two for allowing the access by two sides of the tray ( the two sides are the kintchen and the dining room) because the tray during the passage on the upper crown wheel doesn't rotate on itself but it moves in horizontal way. On every plexiglass (ref. 253) are applied the reference in iron (ref. 274) to activate the proximity switch to stop the rotation of the system and/or to suspend the electrical power supply to the Magnetron and/or at lamp for the sterilization during the operations with the ready dishes.
