Abstract

A bulk bin forming system configured as a container forming cell includes a multi-axis robot to which is attached a multifunction tool. One or more collapsed card board boxes are located at a first station of the container forming cell adjacent the robot. The robot and multifunction tool are configured to operate to grasp and move an individual box, orient and pre-form the box by folding flaps at a second station of the cell, and then move the box to a third station of the cell to mount the box to a support configured as a pallet to thereby form a bulk bin or bulk box container referred to as a gaylord container. The tool may include vacuum grippers for grasping the boxes and staplers for securing the formed box to the pallet, and may also be used to fold the bottom flaps prior to mounting the box to the pallet.

First claim

The embodiments of the invention in which an exclusive property or privilege is claimed are defined as follows:

1. A method of constructing a container, said method comprising:
using a single multi-axis robot arm to which an end effector comprising a tool is mounted to grasp a collapsed box from an input location, with the tool including a gripper for grasping a side panel of the collapsed box, wherein the box includes a plurality of side panels that are foldably connected together and wherein the tool grasps one of the side panels;
lifting the collapsed box with the robot arm to expand the box, wherein lifting the box at the grasped one of the side panels causes the box to expand;
folding flaps on an end of the expanded box with the robot arm;
placing the expanded box on a pallet with the robot arm with the folded flaps adjacent the pallet; and
securing the expanded box while empty directly to the pallet through the folded flaps with the robot arm;
wherein a single expanded box is sized and secured to the pallet to form the container whereby goods may be placed into the expanded box.

2. The method of claim 1 , further comprising placing the expanded box into a first location with the robot arm after said lifting the collapsed box with the robot arm and prior to said folding the flaps on the end of the expanded box, and wherein said placing the expanded box into the first location comprises placing the expanded box against a containment jig.

3. The method of claim 2 , wherein said placing the expanded box against the containment jig comprises placing the expanded box in an upside down orientation whereby the flaps are oriented upwards.

4. The method of claim 2 , wherein said folding the flaps on the end of the expanded box comprises folding the flaps with the tool of the robot arm.

5. The method of claim 1 , further comprising rotating the expanded box with the robot arm after said folding the flaps on the end of the expanded box and prior to said placing the expanded box on a pallet with the robot arm.

6. The method of claim 5 , wherein said placing the expanded box on the pallet with the robot arm comprises placing the expanded box against a jig to orient the expanded box on the pallet.

7. The method of claim 1 , wherein said securing the expanded box to the pallet comprises securing the expanded box to the pallet with the end effector of the robot arm.

8. The method of claim 1 , wherein a stack of collapsed boxes are located at the input location and wherein said using the multi-axis robot arm to which the end effector comprising the tool is mounted to grasp the collapsed box from the input location comprises grasping the collapsed box from the stack.

9. The method of claim 1 , wherein the gripper of the tool comprises a vacuum gripper.

10. A method of constructing a container, said method comprising:
grasping a collapsed box from an input location with a single multi-axis robot arm, wherein the box includes a plurality of side panels that are foldably connected together and wherein the robot arm grasps one of the side panels;
expanding the box with the robot by lifting the grasped one of the side panels such that other of the side panels fold relative to the grasped one of the side panels;

folding flaps on an end of the expanded box with the robot;
placing the expanded box on a pallet with the robot with the folded flaps adjacent the pallet; and
securing the expanded box while empty directly to the pallet through the folded flaps with the robot arm.

11. The method of claim 10 , further comprising placing the expanded box into a first location with the robot after said expanding the box with the robot and prior to said folding the flaps on the end of the expanded box with the robot.

12. The method of claim 11 , wherein said placing the expanded box into the first location comprises placing the expanded box against a containment jig.

13. The method of claim 12 , wherein said placing the expanded box against the containment jig comprises placing the expanded box in an upside down orientation whereby the flaps are oriented upwards.

14. The method of claim 13 , wherein said folding the flaps on the end of the expanded box comprises folding the flaps while the expanded box is positioned against the containment jig in the upside down orientation.

15. The method of claim 10 , wherein said placing the expanded box on the pallet with the robot comprises placing the expanded box against a jig to orient the expanded box on the pallet.

16. The method of claim 10 , wherein said grasping a collapsed box from an input location comprises grasping with an end effector of the robot arm, with the end effector comprising a tool having a gripper.

17. The method of claim 15 , wherein said folding the flaps on the end of the expanded box comprises folding the flaps on the end of the expanded box with the tool of the robot arm.
