Abstract

A system for closing a shipping container that has a rectangular bottom wall, upstanding side walls extending from the periphery of the bottom wall, and an open top end, includes a sled capable of moving the container between a first station and a second station spaced from the first station, and a flap-folding assembly movable with the sled. The flap-folding assembly is configured to inwardly fold flaps of the container while the sled moves the container between the first station and the second station.

First claim

The invention claimed is:

1. A system for closing a shipping container, comprising:
a first station;
a second station spaced from the first station; and
a sled capable of moving a container between the first station and the second station along a path extending in an axial direction, and
a flap-folding assembly mounted to the sled and movable in the axial direction with the sled, the flap-folding assembly configured to inwardly fold flaps of the container while the sled moves the container between the first station and the second station;
wherein the flap-folding assembly includes opposing flap closers, the flap closers being spaced along the path and movable toward each other to inwardly fold flaps of the container; and
wherein the flap-folding assembly is vertically adjustable relative to the sled.

2. The system as set forth in claim 1 , wherein the first station includes a flap-forming assembly configured to form flaps from side walls of a container having a bottom wall and upright side walls extending from a periphery of the bottom wall to define an enclosed volume with an upwardly-opening top end.

3. The system as set forth in claim 1 , wherein the second station is a container-closing station and optionally includes a lidding assembly configured to apply a lid to close the container, where the container has an upwardly-opening top end.

4. The system as set forth in claim 1 , wherein the flap closers include axial flap closers and transverse flap closers coupled to the sled for movement with the sled, the transverse flap closers being spaced apart on opposing transverse sides of the path and movable toward each other to inwardly fold flaps perpendicular to the axial direction.

5. The system as set forth in claim 4 , wherein the transverse flap closers are movable toward each other in a direction perpendicular to the axial direction.

6. The system as set forth in claim 4 , wherein the transverse flap closers are pivotable toward each other about axes parallel to the axial direction.

7. The system as set forth in claim 6 , wherein the transverse flap closers each include multiple fingers mounted on a common shaft that is pivotable about an axis parallel to the axial direction.

8. The system as set forth in claim 4 , wherein the transverse flap closers are adjustable in a direction perpendicular to the axial direction.
