AUTONOMOUS CONTROLS FOR A ROBOTIC CARTON UNLOADER

摘要

Robotic carton unloader has right and left lower arms of robotic arm assembly that are pivotally attached at lower end respectively to mobile body on opposing lateral sides of conveyor system passing there between. Upper arm assembly has rear end pivotally attached at upper end respectively of right and left lower arms to pivotally rotate about upper arm axis perpendicular to longitudinal axis of conveyor system and parallel to lower arm axis. Manipulator head attached to front end of upper arm assembly engages carton/s from carton pile resting on floor for movement to conveyor system. Upper arm axis is maintained at a height that enables carton/s to be conveyed by conveyor system without being impeded by robotic arm assembly as soon as manipulator head is clear. Lift attached between mobile body and front portion of conveyor system reduces spacing underneath carton/s during movement from carton pile to conveyor system.

主权项

1. A robotic carton unloader for unloading a carton pile resting on a floor, comprising:
a mobile body movable across the floor; a conveyor system mounted on the mobile body to convey unloaded cartons thereon; and a robotic arm assembly comprising:
right and left lower arms pivotally attached at a lower end respectively to the mobile body on opposing lateral sides of the conveyor system passing there between to rotate about a lower arm axis that is perpendicular to a longitudinal axis of the conveyor system;an upper arm assembly having a rear end pivotally attached at an upper end respectively of the right and left lower arms to pivotally rotate about an upper arm axis that is perpendicular to the longitudinal axis of the conveyor system and parallel to the lower arm axis; anda manipulator head attached to a front end of the upper arm assembly and engages at least one carton at a time from a carton pile resting on a floor for movement to the conveyor system,wherein the pivotal movement of the right and left lower arms maintains the upper arm axis at a height that enables the at least one carton to be conveyed by the conveyor system without being impeded by the robotic arm assembly.
