Robotic carton unloader with integral extraction mechanism

A robotic carton unloader (100) for unloading a carton pile (106) resting on a floor (118) includes a mobile body (114) movable across the floor on more than one wheel. A conveyor system (110) mountedon the mobile body (114) conveys unloaded cartons thereon. A robotic arm assembly (102) has a manipulator head (136) attached to a front end of the upper arm assembly. The manipulator head (136) engages at least one carton at a time from a carton pile resting on a floor for movement to the conveyor system. A built-in jacking apparatus (166) is extendable from the mobile body (114) to a floor to raise the mobile body a distance sufficient to raise at least one of the more than one wheel (162) away from contacting the floor. 本发明提供了种用于卸载搁置在地板(118)上的纸箱堆(106)的机器人纸箱卸载器(100)，包括可通过多于个轮在所述地板上移动的可移动主体(114)。安装在所述移动主体(114)上的传送机系统(110)在其上传送卸载的纸箱。机器人臂组件(102)具有附接到所述上臂组件的前端的操纵器头(136)。所述操纵器头(136)从搁置在地板上的纸箱堆次接合至少个纸箱，以便移动到所述传送机系统。内置千斤顶装置(166)可从所述移动主体(114)延伸到地板，以使所述移动主体升高足够距离，从而升高所述多于个轮(162)中的至少个使其不接触所述地板。
