Abstract

A method and system are disclosed for the automated accumulation and loading of parts wherein an automated part transfer apparatus is utilized to successively pick up predetermined arrangements of spaced parts from a shuttle at a pair of unloading stations. The part transfer apparatus preferably includes a gantry robot which places the parts in predetermined positions in a container located in the work envelope of the robot. The robot continues to load the parts until the container is full. In the disclosed embodiment, the method and system are utilized for racking automotive parts after they exit a sheet metal processing machine. Preferably, the parts are vertically accumulated in spaced relationship at an accumulator station in which the shuttle aids in the stacking process. A part indexing mechanism also aids in the stacking process at the accumulator station. After the stack of spaced parts is full, the shuttle moves so that a first end of the shuttle containing the spaced parts is located at one of the unloading stations and the opposite, second end of the shuttle moves into the accumulator station. The accumulation process then continues at the second end of the shuttle while the robot is unloading the parts at the first end of the shuttle.
