Abstract
Control circuitry for a work strip stamping machine to control the longitudinal advance and the transverse strip shifting so that a selected number of rows can be automatically stamped, the control being synchronized with the cycle of the stamping member by a sensor that generates an initiating pulse to start the next advance and/or shift of the strip. The circuit includes CMOS flipflops and shift registers that provide a repeating sequence of pulses which are delivered through buffers to the solenoids that actually initiate the advance and shift of the work strip. The circuit is operated from the AC mains, but includes a battery back-up circuit that automatically takes over in the event of a power failure and inhibits further cycling of the system while at the same time maintaining voltage on the CMOS components of the circuit to retain a memory of its status until the AC power is restored.
