ABSTRACT:
A workpiece ejector and transfer apparatus adapted to automatically extract a workpiece from a tool after work has been performed, and thereby reduce the cycle time for the operation. The apparatus includes a cylinder, a pair of cam plates adapted to convert the reciprocating motion of the cylinder into a rotational motion, and an engagement portion adapted to engage and unload the workpiece. When the cylinder is actuated, the cam plates are initially translated in an upward direction, and thereafter rotated. The initial upward translation of the cam plates is intended to engage and lift a processed workpiece such that it has sufficient clearance from its tool, whereas the rotation of the cam plates acts to transfer the processed workpiece such that the tool can accommodate a new workpiece. The processed workpiece is preferably transferred to a temporary retaining device while the new workpiece is loaded.
