ABSTRACT:
A parts feeder is shown illustrated with a rotary type feeder having circular side walls in which the parts are picked up by a feed nozzle on the periphery of the side walls, and delivered to an induction ring assembly in which jets pneumatically transfer the parts into a feed tube which elevates the parts and delivers the same to a dispenser, the latter serving to drop the same onto counter rotating rollers for orientation. The counter rotating rollers are positioned over the rotary feeder so that parts not accepted by the same are dropped into the feeder for recirculation. The steps of the method include delivering parts in a path having feed pressure and unoriented, transferring the parts to an induction ring with means for reversing the parts pneumatically, applying a pulsating cycle to the induction ring so that the parts proceed forwardly and intermittently in a reverse fashion to reduce jamming tendencies, confining the parts after they have passed the induction ring to transfer to a remote location, and thereafter transferring the parts from the confining means to orientation means for delivering the oriented parts.
