Abstract

A method of at least partially erecting a carton with a carton forming system includes loading a blank in a blank infeed assembly, the blank having a plurality of panels and a plurality of end flaps foldably connected to a respective panel of the plurality of panels. The method further includes positioning the blank on at least one conveyor assembly, operating the at least one conveyor assembly to move the blank in a downstream direction of the system toward a carton erection assembly, the carton erection assembly including an end flap engagement assembly positioned adjacent the at least one conveyor assembly, and rotating the end flap engagement assembly such that a portion of the end flap engagement assembly contacts and moves at least one end flap of the plurality of end flaps of the blank as the blank moves in the downstream direction.

First claim

What is claimed is:

1. A method of at least partially erecting a carton with a carton forming system, the method comprising:
loading a blank in a blank infeed assembly of the system, the blank comprising a plurality of panels and a plurality of end flaps foldably connected to a respective panel of the plurality of panels;
positioning the blank on at least one conveyor assembly of the system;
operating the at least one conveyor assembly to move the blank in a downstream direction of the system toward a carton erection assembly of the system, the carton erection assembly comprising an end flap engagement assembly positioned adjacent the at least one conveyor assembly, the end flap engagement assembly comprises a hub member and an end flap engagement lug extending from the hub member; and
rotating the end flap engagement assembly such that the end flap engagement lug contacts and moves a first end flap and a second end flap of the plurality of end flaps of the blank as the blank moves in the downstream direction.

2. The method of claim 1 , wherein the end flap engagement assembly further comprises a hub adapter coupled to the hub member, the end flap engagement lug mounted on an arm coupled to the hub adapter.

3. The method of claim 2 , wherein the method further comprises moving the position of the end flap engagement lug relative to the hub member.

4. The method of claim 3 , wherein the moving the position of the end flap engagement lug comprises moving the end flap engagement lug relative to the arm.

5. The method of claim 3 , wherein the moving the position of the end flap engagement lug comprises moving the arm relative to the hub adapter.

6. The method of claim 3 , wherein the moving the position of the end flap engagement lug comprises moving the hub adapter relative to the hub member.

7. The method of claim 2 , wherein the hub member defines an interior recess for at least partially receiving a drive shaft, and rotating the end flap engagement assembly comprises rotating the drive shaft.

8. The method of claim 1 , wherein the carton erection assembly further comprises an end flap diverting member positioned adjacent the end flap engagement assembly, the end flap diverting member having a sloped upper surface, and the method further comprises moving the blank in a downstream direction into engagement with the end flap diverting member.

9. The method of claim 8 , wherein the moving the blank into engagement with the end flap diverting member comprises moving the first end flap along the sloped upper surface of the end flap diverting member.

10. The method of claim 9 , wherein moving the blank into engagement with the end flap diverting member comprises moving the second end flap of the plurality of end flaps below the end flap diverting member.

11. The method of claim 10 , wherein the carton forming assembly further comprises a carton formation frame positioned adjacent the end flap diverting member, the carton formation frame having a sloped upper surface, and the method further comprises moving the first end flap along the sloped upper surface of the carton formation frame.

12. A carton forming system for at least partially forming a carton, the system comprising:
a blank infeed assembly arranged to receive at least one blank comprising a plurality of panels and a plurality of end flaps foldably connected to a respective panel of the plurality of panels, the blank infeed assembly configured to position the at least one blank along a portion of the system;
at least one conveyor assembly positioned for receiving the at least one blank from the blank infeed assembly, the at least one conveyor assembly configured to move the at least one blank in a downstream direction of the system; and
a carton erection assembly comprising an end flap engagement assembly positioned adjacent the at least one conveyor assembly, the end flap engagement assembly comprises a hub member, an end flap engagement lug extending from the hub member, and a hub adapter coupled to the hub member, the end flap engagement lug mounted on an arm movably coupled to the hub adapter such that the end flap engagement lug is repositionable relative to the hub member,
the end flap engagement assembly rotatably mounted to the system such that the end flap engagement lug is positioned to rotate and move a first end flap and a second end flap of the plurality of end flaps when the at least one blank moves in the downstream direction of the system.

13. The system of claim 12 , wherein the end flap engagement lug is movably coupled to the arm.

14. The system of claim 12 , wherein the hub adapter is coupled to the hub member in selected rotational orientation of a plurality of rotational orientations.

15. The system of claim 12 , wherein the hub member defines an interior recess for at least partially receiving a drive shaft of the system.

16. The system of claim 15 , wherein the end flap engagement assembly further comprises a clamping apparatus operably coupled with the hub member, the clamping apparatus biased toward a preselected position relative to the interior recess to facilitate engagement with a drive shaft of the system.

17. The system of claim 16 , wherein the carton forming assembly further comprises a carton formation frame positioned adjacent the end flap diverting member, the carton formation frame having a sloped upper surface positioned for slidably engaging the first end flap.

18. The system of claim 12 , wherein the carton erection assembly further comprises an end flap diverting member positioned adjacent the end flap engagement assembly, the end flap diverting member having a sloped upper surface positioned for slidable engagement with the end flap.

19. An end flap engagement assembly, comprising:
a hub member, a hub adapter coupled to the hub member, an end flap engagement lug mounted on an arm coupled to the hub adapter, and a hub adapter coupled to the hub member, the end flap engagement lug mounted on an arm slidably coupled to the hub adapter such that the end flap engagement lug is repositionable relative to the hub member,
the hub member defines an interior recess for at least partially receiving a drive shaft such that the end flap engagement lug is positionable to contact and move a first end flap and a second end flap of a blank positioned proximate the end flap engagement assembly when the drive shaft is rotated.

20. The end flap engagement assembly of claim 19 , wherein the end flap engagement lug is movably coupled to the arm.

21. The end flap engagement assembly of claim 19 , wherein the hub adapter is coupled to the hub member in selected rotational orientation of a plurality of rotational orientations.

22. The end flap engagement assembly of claim 19 , wherein the end flap engagement assembly further comprises a clamping apparatus operably coupled with the hub member, the clamping apparatus biased toward a preselected position relative to the interior recess for facilitating engagement with a drive shaft.
