Abstract: A counter device is described for counting workpieces produced by stamping or blanking on a power press of the type having a ram powered by a flywheel through a clutch and crankshaft with the flywheel being powered by an electric motor. The counter is arranged to count only workpieces actually produced and operates by detecting cyclic enegy losses of the flywheel during the actual production of a workpiece.

Abstract: A control means for a robot transfer device in which there are provided control heads including positional sensing devices connected so as to sense the movement of the robot device in each plane, or direction, and coded signal generating means providing a direct readout giving an indication of the exact position of the workpiece at the end of the robot device. In addition, such control heads are connected to suitable electronic memory and control circuits whereby a variety of different predetermined positions can be programmed into the memory, and the various different necessary movements to be performed by the robot device can thus be carried out in sequence, and to a greater degree of accuracy, than in the past. In addition, the invention provides a simple manual programming system for programming the memory circuits with the necessary information concerning the desired predetermined positions of the device.
