SIFTER MACHINE EMBODIMENT WITH COUNTER WEIGHT AND DRIVING
EMBODIMENT
The Related Art
The invention relates to sifter machines wherein grains are subjected to sifting after grinding and swinging embodiment enabling swinging of sifter groups at such sifter machines without weight group.
This invention relates to installation onto only upper two parallel lines, of sjfter machines capable to perform the required swinging action by means of bearing members offset from axis without need for creation of vibration effect for swinging of the sifter groups and also having a swinging embodiment having less effect on the static load of the building where the machine is fixed.
Background of the Invention
After milling in milling machines, cereals are directed to sieving machines for sieving. Sieving machines are containing several places and/or chambers in form of blocks and where the sieving layers are located in the said chambers and swinging is drived by means of rotating weight force with a motor.
Square sieves are widely used in present mills almost without alternatives. Therefore, it is essential to enable use of blocks capable for installation onto the lines where they are fixed. The related art has machines of different techniques and characteristics for sieving the grain products. The important point in sieving machines is to give the swinging motion to the sieving groups where sieving operation is realized. To give the swinging motion is an important technical step. Sieving machine is hung onto upper ceiling of the building where it is mounted for operation. As the circular force created at the machine and/or swinging effect may impact the static of building, as mentioned above, swinging motion constitute an important technical step of the machine.
In the related art several different embodiments are used in regard to swinging embodiment of the sieving machine. For instance, patent application of Rϋter REINHARD numbered DE 3802799 A1 discloses two sieving groups supporting
each other. However, it is only possible to operate two units of two cylinder sieving blocks here. The stated number has not been exceeded. Use of less number of blocks considerably influences production and labor process and costs. And this constitutes negative situation for the producer. In the patent of Rϋter REINHARD, the four sieving machine has to be on upper chassis independent of driving group as it is clamped from eight points, for that reason, the sieve under the patent of Rϋter REINHARD needs a special upper chassis.
In regard to square sieves there is also a beneficial model application made to Turkish Patent Institute on 25.01.2006 by YUKSELiS MAKiNA SAN. TiC. A. S.
The application relates to a sieving machine consisting of sieving blocks swung circularly by means of a driving unit and realizing sieving operation and elevated from ground plane and separated at upper part suspended independent of the said driving unit. The invention especially mentions sieving machine arranged in a manner working by means of lighter driving unit likely to be in a lighter construction and obtained entirely by suspending of sieving blocks.
The above mentioned application is related to sieving blocks of square sieve machines. However, the swinging technique used in the related application has been sample because of falling within the field of the related art. It mentions creation of circular force effect onto sieving blocks by means of installing weight onto shaft of driving center, and sieving blocks swinging by effect of this force to perform the sieving of the grains.
It can be noticed that the sieving machines of the related art can be deformed in a period ranging from 10 years to 20 years in average. The buildings also lose strength by time and use of sieving machines not applying vibration for replacement of the expired sieving machines provides big advantages because a stronger building is to be built from the foundation. The vibration effect cause serious impacts on the static load of the building as well as may cause occurrence of different adverse results in probable cases.
Purpose of the Invention
The purpose of the invention is to move both sieving groups against forces in opposite directions by means of giving motion to driving spindle of the sieving groups of equal weight and to swing two sieving groups at the rate of eccentricity amount of the eccentric part without use of weight.
One of the purpose of the invention is to swing the sieving groups where more sieving blocks are located on parallel upper two lines. For this purpose, two sieving groups operated without use of weight group and supporting each other do not apply vibration to the structure where they are mounted. TrTus, less effeGt is applied on the static of the building and decrease of resistance is also prevented.
Another purpose of the invention is to provide capability of motion of external driving plate sieving group combined in Z form and internal driving plate sieving group combined again in Z form fully independent of each other.
Another purpose of the invention is to provide capability of motion of four passage sifter hung in mono-block form and four passage sifter in H form fully independent of each other.
Another purpose of the invention is to eliminate the vibration by means of a new swinging embodiment and mitigate the static load of the building. And this enables a resistant structure against probable adverse situations. Another purpose of the invention is to obtain a longer life sieving machine by means of elimination of vibration effect and enable longer use of the building where the machine is fixed.
A further purpose of the invention is to mount the four sieving group. on two lines at four points and enable operation driving motor as mounted on sieving upper driving plate depending on the preferred driving system.
Another purpose of the invention is to allow motion of driving pulley that doing eccentric circular motion. Active driving embodiment has been used for it.
A further purpose of the invention is to enable operation of the system at lower energy by means of elimination of power consumed for vibration effect by means of enabling blocks to carry each other.
In order to realize the above mentioned purposes, it comprises one long upper driving plate and one long lower driving plate, single sieving block where the said plates are connected to the said driving shaft by means of at least one eccentric bushing. In order to realize the above mentioned purposes, it contains short upper driving plate connected to the same driving shaft independent from the said single sieving blocks by means of one upper bearing in normal position (without eccentric) and two sieving blocks containing short lower driving plate.

Detailed Description of the Invention
The sieving machine (1 ) comprises sieving blocks (2, 6, 7) connected to swinging members (5.1 ) in a manner providing swinging motion and the said rails (3) fixed onto upper ceiling region of the area where it is located in terms ~ of-th& related art's factors via rails (3), at least one driving unit (8) performing driving effect duty for realization of the required swinging motion, connection band (5) for clamping the swinging members (5.1 ) onto sieving blocks (2), upper connection members (4) for connection to rails (3) and a driving shaft (10) having a key groove (10.1 ), driven from the said driving unit (10). . Regarding the novelty criterion of the invention comprises one long upper driving plate (7.1) and a long lower driving plate (7.2) connected to the said sieving blocks (2), internal sieving blocks (7) housed to the said driving shaft (10) by means of at least one eccentric bushing (14) and a short upper driving plate (6.1 ) housed to the same driving shaft (10) independent of the said sieving-blocks (7)_by means of an upper bearing housing (11 ) in normal position (without eccentric) and two external sieving blocks (6) having short lower driving plate (6.2). It contains bushing key (14.1 ) and key groove (14.2) providing housing of the said plate (7.1 ) to the driving shaft (10) by means of at least one eccentric bushing (14).
Figure 1 shows perspective view of two units of two-sieving blocks_(2) with internal driving plates (7.1 , 7.2) combined in "Z" form.
Figure 2 shows perspective view of two units of two sieving blocks (2) of external driving plates (6.1 , 6.2) combined in "Z" form.
Figure 3; shows view indicating the position where eight-passage sieving unit formed with two sieving blocks (7) combined with driving plates " t6:1 , " 6.2, 7.1 , 7.2) in "Z" form. A sound structure has been formed as this sieving machine is suspended at eight points. Access to driving embodiment is provided from driving embodiment maintenance space (25) located on middle of two sieving blocks and adjustment and maintenance is easy. As the driving embodiment does not have weight group, the need for covering of the members such as bearingJiousjng (11 ,
12, 12.1 ) etc by means of a casing has been eliminated and a simpler and cheaper construction has been provided. Thus, it has also been possible to inspect the problems that might occur in the driving embodiment.
Figure 4 shows sieving machine of twelve formed with triple sieving blocks (7) connected with driving plates (6.1 , 6.2, 7.1 , 7.2) in Z form. This system may provide sieving machines of sixteen, twenty etc. by use of sieving blocks in number of four, five etc.
Figures 5, 6 and 7 show sieving machine of four consisting of sieving groups of two with Z driving plate by connection of single sieving blocks.- The- said sieving groups of two can be connected only from two points and therefore cannot be suspended alone. For that reason, they are mounted on the ground with two pieces of sieving group of two (Figure 5, 6), driving shaft (10) and bearing housing (11 , 12) and are mounted as a whole onto upper two lines at four points (see Figure 7). Figure 8 shows top view of sieving machines of four, eight and twelve mounted in order on upper two mounting lines in two dimension. It shows representative view of mantling and dismantling on two sides of mounting line on the sieving blocks (2) of the sieving frames (13) .
Figure 9 shows views indicating suspension in mono-block forπron the upper two mounting axis by means of swinging members (5.1 ) as it is in conventional systems as whole by means of combination together with driving unit (8) in the middle in a manner two units of sieving group of two are on two sides.
Figure 10 shows eccentric axis sieving group (7) located on two sides outside the plain axis housed sieving group (6). These sieving groups (7) are combined with one or two long and narrow driving plate (7.1 , 7.2) passing through middle of the suspended driving unit and formed in mono-block structure of H shape. H sieving group is suspended in an independent manner on upper two mounting axis by means of swinging members (5.1). At least one alignment member (7.3) providing connection of the said driving plates (7.1 , 7.2) to the sieving blocks (2) and serving as an intermediate part and/or connection between each of two parts is located.
In the end, the sieving blocks (2) are mounted on upper two axis in fours as it is in conventional systems. (See Figure 11 ).
Sieving of conventional four passages suspended in mono-block form and sieving of four passages in H shape are capable to move independent of each other completely. The driving shaft (10) passing through the middle are housed to sieving group of conventional four passages by means of two bearing housings
(11) from the top and the bottom. The driving shaft (10) and H sieving group driving plate (7.1) are housed by one bearing housing (12). Two pieces of sieving group (6,7) are distanced from each other by help of eccentric bushings (14) located in the H sieving group bearing housing.
When it is desired to use H sieving group in heavier duties, it can also consist of two driving plates. (Figure 16, 17, 18, 19)
Two sieving groups (6,7) should be aligned with each other in a manner weights are equal. When motion is driven onto the driving shaft (10), two sieving groups carry each other against forces in the opposite direction of each other and two sieving groups are swung in different directions without use of weight group in eccentricity amount of eccentric bushings (14).
As two sieving groups (6,7) operated without use of any swinging weight group carry each other , no vibration is applied to the structure where they are mounted. Sieving machines are located on upper floors of flour plants, the force applied onto the foundation of the building by the vibration is high and requires construction of stronger buildings. This developed system eliminates the vibration and decreases dynamic load applied onto the building by sieving machines where multi-sieving blocks are located. In Figures 13 and 14 driving shaft (10) is housed to the sieving group by means of sieving block upper bearing housing (11 ) without decentering. It is housed to driving plate (7.1 ) by means of key grooved eccentric bushing (-14)-by-decentering. In this driving embodiment, decentering distance (X) is equal to the existing eccentricity in the bushings and it is not likely to adjust.
In Figures 15 and 16, the key grooved eccentric bushings (14) on the driving shaft (10) are within the bearing housings (11 ) in the lower and upper driving plates (6.1 , 6.2) of the conventional sieving groups.
The bearing housing (12) on the H sieving block driving plate (7.1) contains adjustment eccentric bushing (15).
Decentering distance (X): can be adjusted by loosing fixing bolts (15.2, 15.3) of adjustment eccentric bushing (15). (See Figure 16).
As driving pulley (8.3) will rotate in decentering due to eccentric bushings (14) with key groove located on upper housing (11 ) shown in Figure 15, driving motor (8.4) can be mounted onto upper driving plate (6.1 ) by means of active driving embodiment (19). In such case, a driving bearing housing (20) is mounted onto upper end of the driving shaft (10) after the pulley. Active driving embodiment (19) provides forward-backward motion of active motor stand (21 ) on the wheels (22) with the power received from driving bearing housing (20). The rotating motion on the driving bearing housing (20) is under control of driving wheel (23) and flexible compressing member (24) and provides linear motion at the point where wheels (23) are. Fixed driving unit (8) also contains a driving pulley key (8.1 ) and pulley belt (8.2).
In Figure 17, it is possible to adjust decentering distance by means of inserting secondary eccentric bushings (15, 16) outside the eccentric bushings_(14) with key groove (14.2). Plate fixing bolts (16.1 ) are used to fix the axis plates (16).
In this alternative embodiment, as the driving pulley (8.3) can rotate without leaving center on the upper housing (11) axis, driving motor (8.4) is mounted onto upper driving plate (6.1 ) motor connection stand (9) by help of bolts (9.1 ). Thus, driving motor (8.4) can be mounted on sieving body (see Figures-13,1Aand 17)
Decentering distance (X) can be adjusted by help of secondary eccentric bushings (15) capable to move together with axis plates (16) by loosening the eccentric adjustment bushing (15) bolts (15.2, 15.3) (see Figure 17). Fixing bolt (15.2) realizes tightening and loosing through bushing split (15.1 ). Adjustment of maximum eccentric distance (x) (17) and position where the distance decreases (<X) (18) is provided by means of a split fixing bolt (15.2) and/or a vertical
adjustment bolt (15.3) containing an eccentric adjustment bushing (15) with a bushing split (15.1 ).
Long driving plate sieving group (7) can also be designed in Z shape. See (figure 1 and figure 10). Also short driving plate sieving group (6) can be designed in Z shape. See (figure 1 and figure 10). In case of design of the system in Z shape, a maintenance space (25) is provided (see Figure 3).
Long driving plate (7.1) and long lower driving plate (7.2) are connected to sieving blocks (2) preferably in three ways. See Figures 18 and 19 for H connection type and such H connection consists of two plates (7.1 , 7.2) on upper and lower part and the plates are fixed to sieving blocks (2). Figure 1 shows H type connection. However, the plates here (6.1 , 7.2) have preferably Z or S form. In figure 10, one single plate (7.1 ) is used and it is also likely to conduct such type of connection.
A balancing member (26) can be used to balance the swinging irregularities in distances far from driving shaft and thus outer parts that can move freely can be taken under control.
