Abstract

A method of forming a tray includes obtaining a blank, 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 in a blank feeder assembly of a system for forming a tray, moving the blank to a tray forming assembly, the tray forming assembly including a tray forming assembly, the tray forming assembly including a turret assembly comprising a plurality of female tray forming members, the tray forming assembly further comprising a piston assembly including a male forming member, positioning the blank between the turret assembly and the piston assembly, and moving the piston assembly into at least partial engagement with the turret assembly to form a tray from the blank.

Claims (22)

1 . A system for forming a tray, the system comprising:

an upstream end;

a downstream end;

a blank feeder assembly positioned at an upstream end of the system, the blank feeder assembly comprising a blank infeed configured to receive at least one blank for forming a tray, the blank feeder assembly comprising a blank distribution mechanism configured to engage and move the at least one blank in a machine direction of the system; and

a tray forming assembly positioned downstream from the blank feeder assembly, the tray forming assembly comprising a turret assembly comprising a plurality of female tray forming members, the turret assembly further comprising a turret body rotatably mounted to a portion of the system, the tray forming assembly further comprising a piston assembly comprising a male forming member for being at least partially received in a respective female tray forming member of the plurality of female tray forming members for forming a tray from the at least one blank.

2 . The system of claim 1 , wherein each female tray forming member comprises a tray forming receiver at least partially extending around a tray forming cavity for at least partially receiving a portion of the piston assembly.

3 . The system of claim 2 , wherein at least one flange forming plate is coupled to the respective tray forming receiver, the flange forming plate extending outwardly from the respective tray forming receiver.

4 . The system of claim 2 , wherein the male tray forming member comprises a plurality of sides and a bottom, the male tray forming member for being at least partially received in a respective tray forming cavity.

5 . The system of claim 4 , wherein the plurality of sides of the male tray forming member are obliquely arranged relative to the bottom of the male tray forming member.

6 . The system of claim 5 , wherein the plurality of female tray forming assemblies are circumferentially arranged about the turret body.

7 . The system of claim 4 , wherein the male forming member is for being at least partially received in a respective tray forming cavity for at least partially folding the plurality of panels around an interior of the tray.

8 . The system of claim 7 , wherein the turret body is rotatable for positioning a selected female tray forming member into alignment with the piston assembly.

9 . A tray forming assembly, comprising:

a turret assembly comprising a plurality of female tray forming members, the turret assembly further comprising a turret body rotatably mounted to a portion of a tray forming system; and

a piston assembly comprising a male forming member for being at least partially received in a respective female tray forming member of the plurality of female tray forming members for forming a tray from at least one blank.

10 . The tray forming assembly of claim 9 , wherein each female tray forming member comprises a tray forming receiver at least partially extending around a tray forming cavity for at least partially receiving a portion of the piston assembly.

11 . The tray forming assembly of claim 10 , wherein at least one flange forming plate is coupled to the respective tray forming receiver, the flange forming plate extending outwardly from the respective tray forming receiver.

12 . The tray forming assembly of claim 10 , wherein the male tray forming member comprises a plurality of sides and a bottom, the male tray forming member for being at least partially received in a respective tray forming cavity.

13 . The tray forming assembly of claim 12 , wherein the plurality of sides of the male tray forming member are obliquely arranged relative to the bottom of the male tray forming member.

14 . The tray forming assembly of claim 13 , wherein the plurality of female tray forming assemblies are circumferentially arranged about the turret body.

15 . The tray forming assembly of 12 , wherein the male forming member is for being at least partially received in a respective tray forming cavity for at least partially folding the plurality of panels around an interior of the tray.

16 . The tray forming assembly of claim 15 , wherein the turret body is rotatable for positioning a selected female tray forming member into alignment with the piston assembly.
