Feed system for high rate press - comprises automatically controlled main and secondary arm assemblies with planer trajectory

摘要

An arm is automatically controlled to move motor vehicle piece parts to and from a press. The trajectory of the piece part is plane and the movement law is such that the velocity is high. This allows a high load rate to be achieved. A motor rotates at constant speed to rotate a conical gear assembly to rotate a cranked arm to move in a slot on a rack gear. This causes a toothed crown wheel to rotate a sleeve to which the main arm is attached. This arm supports a sec. arm to which the pincer claws are attached. The motor also rotates a cranked shaft to move a vertical shaft up and down to move the main and sec. arms up and down.
