Abstract

Systems and methods for folding and retaining upper flaps of a box are disclosed. The system includes a conveyor system configured to advance the box at least partially through the system. A flap folding assembly is configured to fold the upper flaps of the box to an open or outwardly folded configuration. The upper flaps are folded outwardly and down towards outer sidewall surfaces of the box in the folded configuration. A bander assembly is configured to apply a band or other restraint to the upper flaps of the box to retain the upper flaps in the folded configuration.

First claim

What is claimed is:

1. A system for folding and retaining upper flaps of a box in an outward or open configuration, the system comprising:
a conveyor system configured to advance the box at least partially through the system;
a flap folding assembly configured to fold the upper flaps of the box to an outward or open folded configuration, the upper flaps being folded outward and down towards outer sidewall surfaces of the box in the folded configuration; and
a bander assembly configured to apply a band or other restraint to the upper flaps of the box to retain the upper flaps in the folded configuration.

2. The system of claim 1 , wherein the flap folding assembly comprises a plurality of flap folders that are configured to fold the upper flaps of the box to a folded configuration.

3. The system of claim 2 , wherein each of the plurality of flap folders is configured to move parallel to a first axis to insert the plurality of flap folders at least partially into an open upper end of the box and retract the plurality of flap folders from the open upper end of the box.

4. The system of claim 2 , wherein the plurality of flap folders comprises a first set of opposing flap folders.

5. The system of claim 4 , wherein the first set of opposing flap folders are configured to move closer together and further apart from one another and parallel to an axis that is generally parallel to a length of the box.

6. The system of claim 4 , wherein the plurality of flap folders comprises a second set of opposing flap folders.

7. The system of claim 6 , wherein the second set of opposing flap folders are configured to move closer together and further apart from one another and parallel to an axis that is generally parallel to a width of the box.

8. The system of claim 2 , wherein each flap folder of the plurality of flap folders comprises an angled plate that is configured to engage one of the upper flaps of the box as the flap folder is at least partially inserted into an open upper end of the box, wherein engagement of the angled plate with the upper flap of the box is configured to bend or deflect the upper flap of the box in an outward direction.

9. The system of claim 8 , wherein each flap folder of the plurality of flap folders further comprises a first clamp member, each of the first clamp members being configured to be positioned adjacent to or against an inner sidewall surface of the box when the flap folders are at least partially inserted into the open upper end of the box.

10. The system of claim 9 , wherein each flap folder of the plurality of flap folders further comprises a second clamp member, the second clamp members being configured to engage inner surfaces of the upper flaps of the box and fold the upper flaps of the box to the folded configuration.

11. The system of claim 10 , wherein the second clamp members are configured to rotate or move linearly to engage and fold the upper flaps of the box to the folded configuration.

12. The system of claim 10 , wherein the first clamp member and the second clamp member from each flap folder are configured to clamp an upper flap and a sidewall of the box therebetween.

13. The system of claim 1 , wherein the bander assembly comprises a banding frame that is selectively movable to a functional position, wherein the banding frame is configured to extend at least partially around the box when in the functional position.

14. The system of claim 13 , wherein at least a portion of the banding frame is configured to be positioned at a height between upper and lower ends of the folded upper flaps of the box when the banding frame is in the functional position, and wherein the bander assembly is configured apply the band or other restraint to the folded upper flaps between the upper and lower ends of the folded upper flaps.

15. The system of claim 1 , further comprising a print assembly configured to print indicia and/or apply a label to a surface of the box.

16. A system for folding and retaining upper flaps of a box, the system comprising:
a flap folding assembly configured to fold the upper flaps of the box to an open or outwardly folded configuration, the upper flaps being folded outwardly and down towards outer sidewall surfaces of the box in the folded configuration, the flap folding assembly comprising:
a carriage assembly;
first and second opposing flap folders connected to the carriage assembly, the first and second opposing flap folders being configured to move closer together and further apart from one another parallel to a first axis; and
third and fourth opposing flap folders connected to the carriage assembly, the third and fourth opposing flap folders being configured to move closer together and further apart from one another parallel to a second axis; and

a bander assembly configured to apply a band or other restraint to the upper flaps of the box to retain the upper flaps in the folded configuration.

17. The system of claim 16 , wherein each of the flap folders comprises an angled plate that is configured to engage an upper flap of the box and outwardly bend or deflect the upper flap.

18. The system of claim 16 , wherein the first and second opposing flap folders and the third and fourth opposing flap folders are configured to move parallel to a third axis, wherein movement of the first and second opposing flap folders and the third and fourth opposing flap folders parallel to the third axis is configured to enable the first and second opposing flap folders and the third and fourth opposing flap folders to be at least partially inserted into or retracted from an open upper end of the box.

19. The system of claim 18 , wherein the carriage assembly comprises a sub-carriage.

20. The system of claim 19 , wherein the sub-carriage comprises one or more first tracks or guides and one or more second tracks or guides, the first and second opposing flap folders being movably connected to the one or more first tracks or guides to enable movement of the first and second opposing flap folders parallel to the first axis, and the third and fourth opposing flap folders being movably connected to the one or more second tracks or guides to enable movement of the third and fourth opposing flap folders parallel to the second axis.

21. The system of claim 20 , wherein each of the flap folders comprises a clamp member that is movable to fold an upper flap of the box to the folded configuration.

22. The system of claim 21 , wherein the clamp members are configured to hold the upper flaps in the folded configuration while the bander assembly applies the band or other restraint to the upper flaps of the box to retain the upper flaps in the folded configuration.

23. A method for folding and retaining upper flaps of a box in an open or outwardly folded configuration, the method comprising:
providing an open box with upwardly extending upper flaps;
folding the upper flaps to an open or outwardly folded configuration, the upper flaps being folded outward and down toward outer sidewall surfaces of the box when in the folded configuration; and
applying a band or other restraint to the upper flaps while the upper flaps are in the folded configuration, the band or other restraint being configured to hold the upper flaps in the folded configuration.

24. The method of claim 23 , further comprising bending or deflecting the upper flaps outwardly prior to folding the upper flaps to the folded configuration.
