Abstract

See full text

A tortilla press utilizing a single sensor provides improved efficiency and accuracy. The press has a belt driven by a motor and a platen driven by a hydraulic cylinder. The motor is controlled by an AC inverter. A programmable logic controller (PLC) controls the AC inverter and hydraulics associated with the hydraulic cylinder of the platen. The PLC coordinates the movement of the belt and the movement of the platen. A sensor detects detectible elements on the belt and sends a signal to the inverter to initiate stopping of the belt. The inverter detects the zero hertz from the motor once the motor and belt have stopped and sends a signal to the PLC indicating that the belt has stopped. The PLC in turn passes a command that sends a signal to bring the platen down.
