Failed roll condom removal apparatus

Abstract

An automatic failed roll condom detection and removal apparatus wherein failed roll condoms are rapidly removed from a testing mandrel such that shut down of the testing and handling equipment is not required. Detection means detect the presence of a failed roll condom on a testing mandrel as it returns from the testing and removal station and ejection means remove the failed roll condom from the mandrel. The ejection means has a series of rotating brushes having relatively stiff bristles, the brushes being mounted on a reciprocating carriage in ascending manner in the mandrel return travel direction. When a failed roll condom is detected, the shuttle carriage return rate is slowed and the rotating brushes are brought into contact with the failed roll mandrel, each brush in succession pushing or rolling the condom higher on the mandrel until the final brush ejects the condom. After the failed roll condom is removed, the brush carriage retracts and the shuttle carriage is brought back up to normal operating speed.

Claims

1. A condom loading, testing and handling apparatus wherein condoms are placed onto mandrels in a loading station, said mandrels travel to a testing station and said condoms are then removed from said mandrels after testing, wherein some of said condoms are failed roll condoms that are not properly removed from said mandrels after testing, said apparatus further comprising a failed roll condom removal apparatus comprising detection means for detecting the presence of a failed roll condom on one of said mandrels and failed roll condom removal means comprising a series of brushes for removing said failed roll condom from said mandrel.

2. The apparatus of claim 1, wherein said brushes are rotating brushes.

3. The apparatus of claim 2, wherein said brushes are located side by side such that all said brushes rotate in the same direction.

4. The apparatus of claim 3, wherein said brushes are disposed in an ascending arrangement relative to the direction of travel of said mandrel during the failed roll condom removal operation.

5. The apparatus of claim 4, wherein said brushes are arranged such that said mandrel is in contacted with at least one of said brushes during the entire removal operation.

6. The apparatus of claim 1, further comprising means to transport said mandrels across said brushes during the removal operation, wherein said failed condom is removed from said mandrel without stopping transport of said mandrels.

7. The apparatus of claim 1, wherein said detection means comprises a photoelectric detector.

8. The apparatus of claim 1, wherein said failed roll condom removal apparatus further comprises means to reciprocate said failed roll condom removal apparatus between an operative position with said brushes in contact with said failed roll condom and a non-operative position.

9. A failed roll condom removal apparatus removing a failed roll condom from a mandrel, said apparatus comprising; detection means to detect the presence of a failed roll condom on a mandrel;a plurality of rotating brushes arranged in ascending order such that the lowermost brush contacts the lowermost portion of said mandrel and said failed roll condom first to push said failed roll condom up said mandrel, with each brush in order thereafter contacting said failed roll condom at a higher location than that of a previous brush, such that said failed condom is ejected from said mandrel;means to reciprocate said brushes between an operative position in contact with said mandrel and said failed roll condom and a non-operative operative position.

10. The apparatus of claim 9, wherein all said brushes rotate in the same direction.

11. The apparatus of claim 9, wherein said brushes are arranged such that said mandrel is in contacted with at least one of said brushes during the entire removal operation.

12. The apparatus of claim 9, wherein said detection means comprises a photoelectric detector.

13. A condom loading, testing and handling apparatus comprising a mandrel receiving a condom thereon for testing purposes, a loading station positioning said condom onto said mandrel, means to transport said mandrel and condom to a testing and removal station and means to transport said mandrel back to said loading station after said condom has been tested; and further comprising a condom removal apparatus distinct from said testing and removal station, whereby in the event said condom is not properly removed from mandrel by said testing and removal station, said condom removal apparatus removes said condom prior to the return of said mandrel to said loading station.

14. The apparatus of claim 13, said condom removal apparatus comprising: means to detect the presence of said condom on said mandrel during return of said mandrel to said loading station; anda plurality of rotating brushes arranged laterally so as to successively contact said condom and said mandrel during said return.

15. The apparatus of claim 14, said brushes of said condom removal apparatus are arranged in ascending manner relative to said mandrel and to the direction of travel of said mandrel during said return.

16. The apparatus of claim 15, said condom removal apparatus further comprising means to reciprocate said brushes from an operative position in contact with said mandrel to an inoperative position.

17. The apparatus of claim 16, said condom removal apparatus further comprising a brush carriage upon which said brushes are mounted, said brush carrier being mounted on tracks such that said brush carriage is reciprocated along with said brushes.

18. The apparatus of claim 14, wherein said detection means comprises a photoelectric detector.

19. The apparatus of claim 14, wherein said brushes are circular brushes rotating in the same direction.

20. The apparatus of claim 13, said condom removal apparatus comprising: means to detect the presence of said condom on said mandrel during return of said mandrel to said loading station; andmeans to eject said condom from said mandrel during said return.
