Abstract

An example pallet auto box with robot palletizer includes a conveyor to move a pallet into a loading area adjacent a robot for loading bags onto the pallet. The example pallet auto box with robot palletizer also includes an auto box having at least one wall, and in an example four walls, that can be raised and lowered. The at least one wall is raised as the robot stacks bags onto the pallet to maintain a border around the edge of the pallet for the bags to be stacked on the pallet. At least one wall opens as a door or gate after the pallet has been loaded with bags so that the loaded pallet can be moved out of the loading area and a next pallet moved into the loading area. The at least one wall is lowered again for stacking bags onto the next pallet.

Claims

1. A pallet auto box, comprising:

a gate; and

at least one wall that raises and lowers adjacent a loading area for a pallet, the at least one wall raising to a first level to receive items on the pallet, the at least one wall raising to a second level to receive more items on the pallet;

wherein the at least one wall is raised to maintain a border around the loading area for the items to be stacked within the loading area on the pallet;

wherein the gate opens after the pallet has been loaded so that the loaded pallet can be moved out of the loading area and a next pallet can be moved into the loading area.

2. The pallet auto box of claim 1, wherein the at least one wall is lowered after the pallet is removed from the loading area for stacking bags onto the next pallet.

3. The pallet auto box of claim 1, further comprising a first conveyor to move the pallet into the loading area.

4. The pallet auto box of claim 1, further comprising a second conveyor to move items adjacent the loading area.

5. The pallet auto box of claim 4, further comprising a robot arm to load items from the second conveyor onto the pallet in the loading area.

6. The pallet auto box of claim 1, further comprising a plurality of walls forming four sides of a box when raised around the loading area.

7. The pallet auto box of claim 1, further comprising a first plurality of walls forming four sides of a box when raised around the loading area.

8. The pallet auto box of claim 7, wherein the first plurality of walls raise to the first level.

9. The pallet auto box of claim 8, further comprising a second plurality of walls forming four sides of a box when raised around the loading area.

10. The pallet auto box of claim 9, wherein the second plurality of walls raise higher than the first plurality of walls to the second level.

11. The pallet auto box of claim 9, wherein the second plurality of walls slidably engage the first plurality of walls.

12. The pallet auto box of claim 7, wherein the first plurality of walls pull away from the loading area after loading the pallet.

13. The pallet auto box of claim 12, wherein the first plurality of walls lower again after loading the pallet.

14. A pallet auto box with robot palletizer, comprising:

a conveyor to move a pallet into a loading area adjacent a robot arm loading bags onto the pallet;

an auto box having four walls, the four walls raise during loading of the pallet to maintain a border around the edge of the pallet for the bags to be stacked on the pallet; and

at least one of the four wall opening as a gate after the pallet has been loaded so that the loaded pallet can be moved out of the loading area.

15. The pallet auto box with robot palletizer of claim 14, wherein the four walls lower after the loaded pallet is moved out of the loading area.

16. The pallet auto box with robot palletizer of claim 15, wherein a next pallet is moved into the loading area.

17. The pallet auto box with robot palletizer of claim 15, wherein the four walls are lowered again for stacking bags onto a next pallet.

18. A method of operating a pallet auto box, comprising:

positioning a pallet on a loading area adjacent items to be loaded onto the pallet;

raising at least one wall of the auto box as the items are stacked onto the pallet to maintain a border around the edge of the pallet for the items to be stacked on the pallet to adjust for different heights by going higher as a stack of the items grows higher; and

opening a door or gate of the auto box after the pallet has been loaded so that the loaded pallet can be moved out of the loading area.

19. The method of claim 18, further comprising raising the at least one wall of the autobox to a first level to load items onto the pallet, and then raising the at least one wall of the autobox to a second level to continue loading items onto the pallet.

20. The method of claim 18, further comprising lowering at least one wall of the auto box loading a next pallet moved into the loading area.
