Abstract
The disclosure describes techniques for erecting cases, and particularly example structures and example methods for use in a case erecting system using a robotic arm. A tool for use in robotic case erecting may be used in conjunction with a robotic arm. Use of the tool assists in keeping a case level as the case moves along a conveyor, where a plow closes the major flaps and a tape head tapes edges of the flaps together, thereby sealing the bottom of the case. The tool also assists in regulating the gap between the major flaps, so that the gap and/or any overlap of the flaps is minimized. Accordingly, the tool assists the robotic arm to close the case in a more precise manner.
Claims10
A system for erecting a case, comprising:
- one or more memory devices;
- a robotic arm, operated by execution of programming defined in the one or more memory devices;
- an end-of-arm tool, connected to an end of the robotic arm and operated by execution of programming defined in the one or more memory devices, which when executed cause the end-of-arm tool to grasp a first side of the case, and to open the case by movements of the robotic arm and end-of-arm tool;
- a plow to fold flaps of the case after the case is opened, wherein the flaps of the case are folded responsive to execution of programming defined in the system that moves the robotic arm to push the case against the plow;
- a tool, operated by execution of programming defined in the one or more memory devices, which when executed cause the tool to grasp a second side of the case, wherein grasping the case by the tool causes the tool to move responsive to movement of the case as the case is moved by the robotic arm;
- and
- a track oriented parallel to a direction of travel of the case, and supporting the tool for movement parallel to the case, wherein the tool moves passively supported by linear bearings sliding on the track, wherein the tool and the track are separated from the robotic arm and the end-of-arm tool by a distance, and wherein movement of the tool motivated by attachment of the tool to the case as the case is propelled by the robotic arm.

- and
- a track, oriented parallel to a direction of travel of the case, to support the tool for movement parallel to the case, wherein the tool and the track are separated from, and not connected to, the robotic arm and the end-of-arm tool, wherein the tool moves passively on the track without motorized power, and wherein movement of the tool along the track results from attachment of the tool to the case as the case is propelled by the robotic arm.
