ABSTRACT:
A sliding member having two gripping devices removes a finished workpiece from a machine and at the same time introduces a blank workpiece. The sliding member carries out a rectilinear feed and return movement, for which it is hydraulically driven. All movements of the two gripping device systems are controlled by cams, including (1) opening and closing the finished part gripping device when picking up the finished part, (2) swivelling the finished part gripping device approximately 90.degree., (3) opening and closing the blank gripping device as the sliding member is returned, (4) again erecting the finished part gripping device when outside of the machine, and (5) stabilizing the blank and finished part gripping devices during movement of the sliding member. To this must be added, if the workpiece is a gear which is to engage a gearlike tool, determining when the workpiece and tool have not meshed and then effecting a repetition of the approach while securely maintaining the blank workpiece in the blank gripping device.
