Abstract
A carton feeder for a continuous motion packaging machine includes a speed compensation controller and a solenoid dual valve assembly, which enable the feeder to operate at higher speeds. The dual valve assembly includes a vacuum valve coupled to an air pressure valve which is controlled by an electronic controller. The speed compensation assembly is electronically connected to the valve controller, and includes an encoder driven by the feeder and a programmable limit switch for receiving data from the encoder and transmitting control signals to the valve controller. The method of operation includes detecting the position of the selector and transmitting position data to the limit switch. The limit switch calculates optimum valve actuation timing based upon both programmed information and data from the encoder, and transmits the control signals to the valve controller.
