Abstract

The invention relates to a picking line for inserting products into a packaging container, having a conveyor belt for the delivery and the transport of products in a transport direction, and at least one picker equipped with a position image processing system for determining the position of the products on the conveyor belt. A quality image processing system is disposed in the transport direction upstream of the at least one picker for checking the products passing the quality image processing system on the conveyor belt in the transport direction for predetermined quality features, and for associating quality information to be transmitted to a picker adjacent downstream of the quality image processing system in the transport direction, serving as a control command for grasping or not grasping the products.

Claims

1-9. -9. (canceled)

10. A picking line for inserting products into a packaging container, having:

a conveyor belt for supplying and transporting products in a transport direction;

at least one picker equipped with a position image processing system for determining the position of the products on the conveyor belt;

a quality image processing system disposed upstream of the at least one picker in the transport direction which inspects the products, which pass by the quality image processing system on the conveyor belt in the transport direction, with regard to predetermined quality features, and which associates a piece of quality information that serves as a control command for grasping or not grasping the products, to a subsequent picker downstream of the quality image processing system in the transport direction.

11. The picking line as recited in claim 10, wherein at least a first picker and a subsequent picker, each equipped with a position image processing system, are situated one after another in the transport direction;

are provided to transmit the quality information serving as a control command for grasping or not grasping the products and the position data for the products not grasped by the first picker to the subsequent picker.

12. A method for inserting products into a packaging container by means of a picking line having a conveyor belt for supplying and transporting products in a transport direction and having at least one picker associated with the conveyor belt, equipped with a position image processing system for determining the position of the products on the conveyor belt, comprising the steps of:

inspecting the products with a quality image processing system situated upstream of the at least one picker in the transport direction with regard to predetermined quality features, while

passing the products by the quality image processing system on the conveyor belt in the transport direction, and

associating a piece of quality information that serves as a control command for grasping or not grasping the products, to a subsequent picker downstream of the quality image processing system in the transport direction.

13. The method as recited in claim 12, wherein at least a first picker and a subsequent picker, each equipped with a position image processing system, are situated one after the other in the transport direction, the method further comprising the step of transmitting the quality information serving as a control command for grasping or not grasping the products and the position data for the products not grasped by the first picker to the subsequent picker.

14. The method as recited in claim 13, wherein in an event of a failure of an image processing system or a picker, it is possible for the quality information serving as a control command for grasping or not grasping the products and the position data for the products not grasped by this picker to be transmitted to a next picker.

15. The method as recited in claim 12, wherein in an event of a failure of one picker, the picker preceding a failed picker transmits the quality information serving as a control command for grasping or not grasping the products and the position data for the products not grasped by the failed picker to a picker subsequent to the failed picker.

16. The method as recited in claim 12, wherein shape and color of the products and presence of graphic features on the products are evaluated as quality criteria.

17. The method as recited in claim 13, wherein shape and color of the products and presence of graphic features on the products are evaluated as quality criteria.

18. The method as recited in claim 14, wherein shape and color of the products and presence of graphic features on the products are evaluated as quality criteria.

19. The method as recited in claim 15, wherein shape and color of the products and presence of graphic features on the products are evaluated as quality criteria.

20. The method as recited in claim 12, wherein the products are depicted on a screen and the quality features detected by the quality image processing system for the products are displayed.

21. The method as recited in claim 13, wherein the products are depicted on a screen and the quality features detected by the quality image processing system for the products are displayed.

22. The method as recited in claim 14, wherein the products are depicted on a screen and the quality features detected by the quality image processing system for the products are displayed.

23. The method as recited in claim 15, wherein the products are depicted on a screen and the quality features detected by the quality image processing system for the products are displayed.

24. The method as recited in claim 16, wherein the products are depicted on a screen and the quality features detected by the quality image processing system for the products are displayed.

25. The method as recited in claim 20, wherein the products detected by the position image processing system are highlighted separately on the screen.

26. The method as recited in claim 21, wherein the products detected by the position image processing system are highlighted separately on the screen.

27. The method as recited in claim 22, wherein the products detected by the position image processing system are highlighted separately on the screen.

28. The method as recited in claim 23, wherein the products detected by the position image processing system are highlighted separately on the screen.

29. The method as recited in claim 24, wherein the products detected by the position image processing system are highlighted separately on the screen.
