Abstract

A method for loading a container with packages, using a device having at least one guide. At least one hand element is displaceable in the longitudinal direction of the guide, and is provided on the at least one guide. The hand element has a plurality of finger elements. The finger elements have at least two flexible flank elements extending together from one end of the finger element to the opposing end. The at least two flexible flank elements of the finger elements are flexibly connected together via a plurality of webs. The finger elements may be adjusted from at least one curved position into at least one extended position and back. The at least one hand element takes packages one after the other, and deposits the packages into the container in a stack. The hand element is displaced along the guide between the deposit of two successive packages.

First claim

What is claimed is:

1. Method for loading a container with packages, with a guide device comprising at least one guide, wherein at least one hand element is provided on the at least one guide device, wherein the hand element has a plurality of finger elements, wherein the finger elements in each case have at least two flexible flank elements extending together from one end of the finger element to the opposing end of the finger element, wherein in each case the at least two flexible flank elements of the finger elements are flexibly connected together in each case via a plurality of webs, so that the finger elements in each case may be adjusted from at least one curved position into at least one extended position and back,
in which the at least one hand element takes packages one after the other,
in which the at least one hand element deposits into the container the packages which have been taken one after the other in the form of a stack of packages and
in which the at least one hand element is displaced along the at least one guide at least between the deposit of two successive packages.

2. Method according to claim 1 , wherein the at least one hand element and/or at least one finger element is adjusted via a drive unit for adjusting the at least two flank elements in a longitudinal direction of the finger element relative to one another from a curved position into an extended position and/or back.

3. Method according to claim 1 , in which the at least one hand element and/or at least one finger element is used with at least one pressure sensor, and
wherein the at least one pressure sensor detects the pressure on the at least one hand element and/or on at least one finger element.

4. The method of claim 3 , wherein the at least one pressure sensor is on at least one flank element, and
wherein the at least one pressure sensor detects the pressure on at least one flank element of at least one finger element.

5. Method according to claim 1 , in which the packages are taken by the at least one hand element from a conveying device, and/or
in which the packages are deposited in the container by the at least one hand element at least substantially in layers on top of one another.

6. The method of claim 5 , wherein the conveying device is a belt conveying device.

7. The method of claim 6 , wherein the belt conveying device is a telescopic belt conveyor.

8. The method of claim 5 , wherein the packages are deposited one after the other.

9. Method according to claim 1 , in which the loading space of the container to be loaded with packages, the layer of the stack of packages already deposited by the at least one hand element, the contour of the stack of packages already deposited by the at least one hand element and/or the contour of the front face of the stack of packages already deposited by the at least one hand element are at least partially detected by a sensor.

10. The method of claim 9 , wherein the sensor is an optical sensor.

11. The method of claim 10 , wherein the optical sensor is a camera.

12. The method of claim 9 , wherein the movement of the hand element is at least partially controlled, depending on the loading space detected by the sensor and/or position of the stack and/or contour of the stack.

13. Method according to claim 1 , in which the at least one hand element is displaced along the at least one guide, depending on the loading space, on the height of the stack of packages, on the layer of the stack of packages, on the contour of the stack of packages and/or on the contour of the front face of the stack of packages.

14. Method according to claim 1 , in which the at least one hand element and/or the at least one guide of the guide device is adjusted forward and/or back.

15. The method of claim 14 , wherein the at least one hand element and/or the at least one guide is adjusted forward and/or back, depending on the loading space, on the height of the stack of packages, on the layer of the stack of packages, on the contour of the stack of packages and/or on the contour of the front face of the stack of packages.

16. Method according to claim 1 , in which the at least one hand element and/or the at least one guide of the guide device is adjusted to the left and/or to the right.

17. The method of claim 16 , wherein the at least one hand element and/or the at least one guide is adjusted forward and/or back, depending on the loading space, on the height of the stack of packages, on the layer of the stack of packages, on the contour of the stack of packages and/or on the contour of the front face of the stack of packages.

18. Method according to claim 1 , in which the at least one hand element and/or the at least one guide of the guide device is adjusted upwardly and/or downwardly.

19. The method of claim 18 , wherein the at least one hand element and/or the at least one guide is adjusted upwardly and/or downwardly, depending on the loading space, on the height of the stack of packages, on the layer of the stack of packages, on the contour of the stack of packages and/or on the contour of the front face of the stack of packages.

20. Method according to claim 1 , in which the at least one guide device, the at least one guide and/or the at least one hand element for depositing further packages is moved in a stepwise manner into the container, further into the container, further in the direction of a position outside the container and/or is moved out of the container.

21. The method of claim 20 , wherein the at least partial movement into the container, the movement in the direction of a position outside the container and/or the movement out of the container takes place depending on the loading space, on the height of the stack of packages, on the layer of the stack of packages, on the contour of the stack of packages and/or on the contour of the front face of the stack of packages.

22. Method according to claim 1 , in which the at least one hand element is connected via a multi-axle arm to the guide device, to the at least one guide, to a further guide, in which the at least one hand element which is held by the multi-axle arm is pivotable about at least two different pivot axes of the multi-axle arm.

23. Method according to claim 22 , in which an uppermost layer of packages of the stack of packages is deposited in the container by the at least one hand element which is held by the multi-axle arm.

24. The method of claim 23 , wherein the uppermost layer of packages of the stack of packages is arranged below the upper end of the loading space and/or the roof of the container.

25. The method of claim 24 , wherein the uppermost layer of packages of the stack of packages is arranged adjacent to the upper end of the loading space and/or the roof of the container.

26. Method according to claim 2 , in which at least one lower layer of packages of the stack of packages is deposited into the container by at least one lower hand element, and
in which at least one upper layer of packages of the stack of packages is deposited into the container by at least one upper hand element which is held by a multi-axle arm on the associated guide.

27. The method of claim 26 , wherein the at least one lower hand element is not held by a multi-axle arm on the assigned guide.

28. The method of claim 26 , wherein the lower hand element and the upper hand element may be held on diff
