FIELD OF THE INVENTION

The present invention relates to a machine which could be used for testing and rolling condom in condom manufacturing companies. More preferably, a machine for hygienic condom production with an automatic loading for pinhole detection and rolling into a ring for further packing. It involves all automatic and hygienic operation from testing, rolling till packaging, wherein the present invention provides a configuration of three moving twine that are effectively taking part in positioning the hung condom to upright position for further inserting of metal condom-shaped mold before electronic testing for pinhole. BACKGROUND AND PRIOR ART OF THE INVENTION

Condoms provide one of the most important means of preventing pregnancy and the spread of human immunodeficiency virus (HIV) and other sexually transmitted diseases. There are four vital steps to making a latex condom: 1) acquiring the resources, 2) shaping the condom, 3) testing the condom, and then 4) packaging it to be shipped out all over the world.

Pinhole defects while shaping the condom may lead to the passage of sperm or viruses through the condom wall. Also, embedded particles, which may become dislodged in handling or use, may represent latent pinhole defects. Thin regions in the condom wall may lead to breakage in use. Testing for such defects (Pinhole, particle, thin wall) in regulatory laboratories, or in the factories as part of production screening or quality assurance efforts, is a major tool for ensuring condom reliability.

Now a days most of the famous condom manufacturing companies are manually putting the condom on shaft (metal condom shape rod) for testing and rolling in ring before packaging. It takes lots of man power and care also. As it is hygiene product, skill and healthy people need to do the same.

Indian Patent application no, 2354/MUM/2012 discloses a CONDOM ROLLING & PACKING MACHINE, wherein pair of moving twines brings a plurality of condoms towards a rotary disc assembly. Before approaching the said rotary disc assembly, air is blown into the condoms for enlargement, and thereafter the inflated condoms are sequentially received and a shaft protrudes from the bottom of the rotary disc assembly enters into the condom, keeps it tight and upright over the rotary disc assembly for further testing and rolling into a ring. Though, the said machine is time inefficient in the overall packaging, but it involves manual handling process in step of segregation of intermixed condom while placing each condom on a moving twine in a required position i.e. upright (while blown an air into the condoms for enlargement). Hence, due to the very fact that it was a manual process, complete automation was not achieved. The fact that, a condom is a medical product and as such are subject to the corresponding health regulations of each country or region. These health regulations regulate the marketing conditions, quality controls and other requirements that condoms must comply with for sanitary approval, in order to ensure suitable reliability in use. Hence, there is a need to develop a machine which has all automatic operation from segregation, mounting on metal shaft, testing, rolling till packaging. As stated above, the problem in prior art machine is manual segregation of each condom for putting it on moving twine as well as worker skill involved to confirm the right position to hang condom on twine for blowing up. So, in accordance to present invention and while developing an automatic operation of this work sequence, inventors have developed a machine which will automatically (without intervention of human) segregates the intermixed condom in rotating drum and individually hang on the moving twin. In addition to this, the present invention provides a configuration of three moving twine that are effectively taking part in positioning the hung condom to upright position for further inserting of metal, condom-shaped mold before electronic testing for pinhole.

Wherein, said machine can be configured to attach a plurality of segregation assembly (101) consisting of rotating drums with corresponding transportation assembly (102) with a central rotating disc (103) assembly. Wherein the manufactured condom lot can be loaded in each drum and rolled condom can be collected at six different outlets and make available for automatic packaging system.

As illustrated in figure 3, the transport assembly (102), may be designed, for example, as revolving three set of twine in a close-loop, that is to say the first twine (25), second twine (25a) and third twine (37) are arranged at a fixed location parallel or one above the other forming a conveyer to transport the hung condom in any event during a transferring operation.

Accordingly, a figure 3 and 4 is a view showing a coupling structure and a twine portion of the transportation assembly according to the first embodiment of the present invention, a fully automatic electronically integrated condom testing and rolling machine (100), wherein said transport assembly 2 comprises a first twine loop (25), second twine (25a), third of twine set (37) and metallic brush (31) shown in figure 4(A). Wherein twine is integrally formed of plastic, fiber, metal or combination thereof. The said plurality of guided and movable twine are consisting of a first twine path (25), second coordinating twine (25a) and third twine set (37).

Wherein first twine path (25) is single unit loop forming elongated circle in and out of the drum guided on a plurality of pulley (27) using electric motor for hanging condoms on it. A second coordinating twine (25a) coordinates parallelly with a first twine path (25) in its middle way thereby forming a twine pair based conveyer to receive the hung condom from first twine path and holding the condom rim in between the pair gap while moving forward.

And third twine set (37) is pair of twine guided on a plurality of pulley (27) using electric motor and adjusted below the second twin to receive the condom in the upright positioned.

In accordance to one more embodiment, a second coordinating twine (25a) is configured with pneumatic divider (44) to wide open the twin pair for dropping the condom in an upright position on to the third twine set (37). The working of said plurality of twines and their internal coordination is that as shown in Figure 3 and 4, condom (a) has been fallen over twine (25) from the rotating drum (23), while moving it reaches the second twine set (25a) which touches the twine (25) in the half way of first twine and wherein each twine is guided on multiple required pulley by moving in same direction thereby forming a twine based conveyer to receive the hung condom from first twine at the starting point and hold the condom in between the pair of said close twine while moving ahead.

A brush (31) placed below the second twine set, includes a plurality of metallic flat portion formed on the radially outer side of the brush to touch a trapped condom (a) and exert a pulling effect on the body of condom, thereby the trapped condom pulled down till the rim of condom touches to twine (condom position a2). That is, due to this configuration of brush 31, at the end portion of second twine set each trapped condom is always remain in upright (condom rim at the top and body at the bottom) position. Thus, the brush 31 pull and drop the condom back into rotating drum if rim is at the bottom side direction.

Lastly, the trapped condom (a2) reached to end of twine (25-25a) and trapped condom is dropped between pair of third twine set (37), wherein a second coordinating twine (25a) is configured with pneumatic divider (44) to wide open the twin pair for dropping the condom in an upright position on to the third twine set (37).

The third twine is pair of twine moving and adjusted below the second twin end to receive the upright positioned condom (Position of condom a3). It is an important aspect of present invention that each condom conveyed to the third twine is in upright position with rim hold between twine set (37) and ready to mount on mounting station.

Once all the above processes are completed in the segregation followed by transportation of individual condom from segregation and transport assembly respectively, the condom is passed on to the adjacent rotary disc station (3) as illustrated in figure 5.

As illustrated in figure 5, there is configuration between rotating drum (23) with optional rod (24) to separate lots and transport assembly twines, at the end of third twine, there is provided with condom mounting unit comprising of condom holder (41) and condom mouth opener (18). Where condom received from transport assembly (last twine 37) are inserted on the metallic condom shape shaft (9) placed just below the opener (18), individually by picking with picker (42) and mouth opening (18). Additionally, the figure illustrates that there provided twine guide pulley (30), drive pulley (33) attached to brush pulley (32), revolving drum driving pulley (34), revolving belt (35), twine divider (43), twine adjustable guide pulley (39) and servo motor (26, 38), condom shaft locking and opening pin (13) and reciprocate unit (11). In accordance to this, rotary disc station (3) (base plate 3 shown in figure 6) of present invention relates to a feeding, testing and rolling system for a condom machine to provide in which the inverted wide opened mouth condom is fed on to the shaft (9) (condom shape having diameter greater than condom internal diameter) of rotating table by three stage rotating impeller force feeding system' so as to mounting on to a shaft of the rotating table and be testing while passing between the path of electric testing unit (22) and finally rolling into a condom ring. Wherein while passing from the testing wide path, the shaft is under control revolution (atleast 5 to 10 revolution) so that all sides of condom gets exposed to electric circuit unit for 5 to 10 times for repetitive pinhole detection.

Figure 7 illustrates the view of housing (1) having central main central shaft (3) configured with geared servo motor (7) to rotate the rotary disc station, while insertion of condom on shaft position (right side shaft) and rolling position (left side shaft), configured with condom shaft locking and opening pin (13) and reciprocate unit (11), puller and pusher unit (12), guide bush (15), shaft lock (17), bottom bearing housing (2), top bearing housing (6), support (14).

In another aspect, and feature, the condom rested on the rotating shaft on the disk guided by shaft/puller and pusher unit/geared servo motor/bearing housing/brakes/sensor, are held in position with any mechanism to clamp them in fixed point for desired operation, additionally the shafts are held locked at the testing section by virtue of the locking and opening pin, thus making the unit far faster to operate and automatable.

A method of operation of an automated electronically integrated condom testing and rolling machine (100) with a rotary disc assembly (103), it holds the plurality of received condoms along a circular periphery. A stationary electronic sensor sequentially evaluates the quality of the plurality of condom held in the upright position by the rotary disc assembly. A rolling unit rolls the plurality of condoms evaluated by the electronic sensor. An ejector is triggered by the electronic sensor to collect the rolled condoms from the rotary disc assembly for rejecting a set of the rolled condoms. A lubrication and packaging device extracts from the rotary disc assembly, another set of rolled condoms for lubrication and packaging.

Accordingly, the embodiment of present invention, method of working of an electronically integrated condom rolling and testing machine (100), a defined automated segregation is consequently done in which an intermixed condoms are loaded inside the rotating elongated drum which is open on both the sides designed with channel along its circumference through which an small condom lot is led onto first set of twine section having tensile forces applied and arranged to circulate in a loop parallel to the axis of drum rotation. Further, the said drum is also configured with brush at the lower side to exert a pulling effect on hung condom and bringing down till it fix in an upright position on the guided twine.

The rotary disc assembly (103), it holds the plurality of received condoms on shafts along a circular periphery thereof while rotating. For executing such holding, a shaft (9), protrudes from the bottom of the rotary disc assembly (5) enters into the condom, keeps it tight and upright over the rotary disc assembly.

While the rotary disc assembly (5) rotates, a pinion and rack mechanism helps the shaft (9) rotate on its own axis separately for a thorough check of the condom from all sides. A stationary electronic sensor sequentially evaluates the condom held over the rotary disc assembly for any damage based on a pre-determined criteria as configured therein. Thereafter, upon triggering by the sensor, the shaft goes down and the condom also rolls down by the help of a rolling unit (16). Such rolling unit may be a condom roller belt. An ejector/separator (19), after receiving signal from the sensor, rejects and pulls out the damaged condoms not satisfying the pre- determined criteria. On the other hand, the non-damaged or fit condoms that satisfy the pre-determined criteria are retained and sent to an accepted bin. Finally, the next step, the accepted bin pulls the condom towards the packaging table.

While specific language has been used to describe the disclosure, any limitations arising on account of the same are not intended. As would be apparent to a person skilled in the art, various working modifications may be made to the machine in order to implement the inventive concept as taught herein.
