Abstract

A device and a method for infeeding products ( 10 ), wherein the device comprises at least one infeed ( 12 ) which infeeds products ( 10 ) to a transportation system ( 20 ), and comprises at least one sensor ( 28 ) for identifying products ( 10 ) which are backed up, wherein at least one ejection means ( 14, 16 ) for removing at least one product ( 10 ) which is located and backed up on the infeed ( 12 ) is provided.

First claim

What is claimed is:

1. An infeed device comprising:
at least one infeed ( 12 ) which infeeds products ( 10 ) to at least one transportation system ( 20 ),
at least one sensor ( 28 ) for identifying products ( 10 ) which are backed up, and
at least one ejection means ( 14 , 16 ) for removing at least one product ( 10 ) which is identified and backed up on the infeed ( 12 ),
wherein the infeed ( 12 ) includes a conveyor that remains activated and moving while the at least one ejection means ( 14 , 16 ) is active.

2. The device according to claim 1 , characterized in that the ejection means ( 14 , 16 ) is disposed between the infeed ( 12 ) and the transportation system ( 20 ).

3. The device according to claim 1 , characterized in that the ejection means includes at least one nozzle.

4. The device according to claim 1 , characterized in that the ejection means ( 14 , 16 ) in relation to the infeed ( 12 ) is disposed such that the product ( 10 ) is removed from the infeed ( 12 ) in a manner substantially transverse to a transportation direction ( 18 ) of the infeed.

5. The device according to claim 1 , characterized in that at least one further ejection means ( 14 , 16 ), which is disposed remote from the at least one ejection means ( 14 , 16 ), is provided in order to preclude infeeding of further products ( 10 ).

6. The device according to claim 1 , further comprising at least one container ( 30 , 32 ) for receiving the at least the product ( 10 ) which is removed by the ejection means ( 14 , 16 ) from the infeed ( 12 ).

7. The device according to claim 1 , characterized in that for removing at least one backed up product ( 10 ), the transportation system ( 20 ) is actuated to an operating mode which deviates from a normal operating mode.

8. The device according to claim 1 , characterized in that the ejection means ( 16 ) is disposed such that at least one backed up product ( 10 ) may be expelled counter to a transportation direction ( 21 ) of the transportation means ( 20 ) in the normal operating mode.

9. The device according to claim 1 , further comprising at least one lateral guide ( 22 , 24 ) for guiding at least one product ( 10 ) which is located on the infeed ( 12 ).

10. The device according to claim 1 , characterized in that the ejection means includes an air-stream generating nozzle.

11. The device according to claim 1 , characterized in that for removing at least one backed up product ( 10 ) the transportation system ( 20 ) is actuated to an operating mode which deviates from a normal operating mode, so as to be counter to a usual transportation direction ( 21 ).

12. The device according to claim 1 , characterized in that after removal of at least one product ( 10 ) from the infeed ( 12 ), at least one lateral guide ( 22 ) is configured to be moved back to a normal position.

13. The device according to claim 1 , characterized in that at least one lateral guide ( 22 ) is movable.

14. The device according to claim 13 , wherein the at least one lateral guide ( 22 , 24 ) is movable from a first position along the at least one infeed ( 12 ) to a second, retracted position along the at least one infeed ( 12 ), such that the at least one ejection means ( 16 ) may eject the at least one product ( 10 ) from the at least one infeed ( 12 ) when the at least one lateral guide has been moved to the second position.

15. A method for infeeding products ( 10 ), comprising:
infeeding products ( 10 ) with an infeed ( 12 ) to at least one transportation system ( 20 ),
identifying backed up products ( 10 ) with a sensor ( 28 ), and
removing, with at least one ejection means ( 14 , 16 ), at least one product ( 10 ) which is identified and backed up on the infeed ( 12 ),
wherein the infeed ( 12 ) includes a conveyor that remains activated and moving while the at least one ejection means ( 14 , 16 ) is active.

16. The method according to claim 15 , characterized in that a further ejection means ( 14 , 16 ) removes at least one incoming product ( 10 ) from the infeed ( 12 ).

17. The method according to claim 15 , characterized in that for ejecting a product ( 10 ), the transportation system ( 20 ) is actuated to an operating mode which deviates from a normal operating mode.

18. The method according to claim 15 , characterized in that a lateral guide ( 22 , 24 ) is moved from a first position along the at least one infeed ( 12 ) to a second, retracted position along the at least one infeed ( 12 ), such that the at least one ejection means ( 16 ) may eject the at least one product ( 10 ) from the at least one infeed ( 12 ) when the lateral guide ( 22 , 24 ) has been moved to the second position.

19. The method according to claim 15 , characterized in that the transportation system ( 20 ) is displaced in an opposite direction.

20. The method according to claim 15 , characterized in that the ejection means ( 14 , 16 ) removes at least one product ( 10 ) which is located between the infeed ( 12 ) and the transportation system ( 20 ) from the infeed ( 12 ).

21. An infeed device comprising:
at least one infeed ( 12 ) which infeeds products ( 10 ) to at least one transportation system ( 20 ),
at least one sensor ( 28 ) for identifying products ( 10 ) which are backed up,
at least one ejection means ( 14 , 16 ) for removing at least one product ( 10 ) which is identified and backed up on the infeed ( 12 ), and
at least one movable lateral guide ( 22 , 24 ) that is movable from a first position along the at least one infeed ( 12 ) to a second, retracted position along the at least one infeed ( 12 ), such that the at least one ejection means ( 16 ) may eject the at least one product ( 10 ) from the at least one infeed ( 12 ) when the at least one lateral guide has been moved to the second position.

22. An infeed device comprising:
at least one infeed ( 12 ) which infeeds products ( 10 ) to at least one transportation system ( 20 ),
at least one sensor ( 28 ) for identifying products ( 10 ) which are backed up,
at least one first ejection means ( 14 , 16 ) for removing at least one product ( 10 ) which is identified and backed up on the infeed ( 12 ), and
at least one further, second ejection means ( 14 , 16 ) which is disposed remote from the at least one first ejection means ( 14 , 16 ), wherein the second ejection means ( 14 , 16 ) is provided in order to preclude infeeding of further products ( 10 ).

23. An infeed device comprising:
at least one infeed ( 12 ) which infeeds products ( 10 ) to at least one transportation system ( 20 ),
at least one sensor ( 28 ) for identifying products ( 10 ) which are backed up, and
at least one ejection means ( 14 , 16 ) for removing at least one product ( 10 ) which is identified and backed up on the infeed ( 12 ),
wherein for removing at least one backed up product ( 10 ), the at least one transportation system ( 20 ) is actuated to an operating mode which deviates from a normal operating mode.

24. The infeed device of claim 23 , wherein the at least one transportation system ( 20 ) moves in a transportation direction ( 21 ) to move the products ( 10 ) during the normal operating mode, and wherein to remove the at least one backed up product ( 10 ) in the operating mode, the at least one transportation system ( 20 ) moves in a direction opposite the transportation direction ( 21 ).
