Abstract
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.
