Abstract:
1. A robotic mail tray sleeving system comprising: a conveyor system for transporting a mail tray; a sleeve blank presentment device, the sleeve blank presentment device comprising a plurality of sleeve cartridges, each sleeve cartridge configured to hold a plurality of sleeve blanks in a generally vertical orientation; a robotic arm; an end of arm tool coupled to the robotic arm, the end of arm tool configured to retain and open a sleeve blank selected from the sleeve blank presentment device, the robotic arm configured to move the end of arm tool between a generally vertical orientation for selecting a sleeve blank from a sleeve cartridge and a generally horizontal orientation for placing the sleeve blank on the conveyor system, the end of arm tool comprising a base, a suction head, and an arm pivotally coupled to the base and configured to open a sleeve blank while the sleeve blank is retained by the suction head; and a tray induction system including a plurality of paddles configured to guide the mail tray into an opened sleeve blank, wherein each sleeve cartridge is pitched relative to a horizon such that the robotic arm is configured to remove a lower most sleeve blank from the sleeve cartridge.
