Abstract: A method and apparatus are disclosed for the automated loading of parts wherein multiple gantry robots are utilized to pick up automotive parts from movable transfer beds and placed into predetermined positions in containers which are serially indexed through the work envelopes of the robots until the containers are full. In the disclosed embodiment, the method and system are utilized for racking automotive parts after they exit a sheet metal stamping machine. Preferably, empty containers are automatically delivered to a container queue such as by an automatic guided vehicle system (AGVS) at an unloading station adjacent the robots. Thereafter each AGV is moved to a loading station to receive and retain thereon containers loaded with parts by the gantry robots.

Abstract: A method for changing the tooling in a robot-based material transfer system is disclosed as well as a system utilizing the method. The tooling is changed to accommodate the transfer of material such as automotive parts having different configurations within the system. Initially, end effectors of gantry robots and/or transfer beds of the system are placed in at least one container which is indexed through the work envelopes of the robots. Then, at least one specially designed container containing new tooling is indexed into the work envelopes. The robots are controlled to remove the new tooling from the containers and to place the new tooling in operative positions in the system. In the disclosed embodiment, one of the robots utilizes a special transfer bed gripper to replace the old transfer beds with new transfer beds. Preferably, an automatic guided vehicle system (AGVS) moves containers to and from loading and unloading stations in the material handling system.
