Abstract
A suck back type intermittent coating system including a valve mechanism, a valve manipulating mechanism, and a solenoid valve for controlling the operation of the valve manipulating mechanism; and a control device that inputs therein a pulse signal indicative of the travel state (travel speed, etc.) of a base material traveling along a coating line, and outputs an electrical command to the solenoid valve. A displacement sensor for detecting a displacement of the movable valve body of the valve mechanism is provided so that the operation of the valve manipulating mechanism is remotely controlled by a command signal to the solenoid valve; and with a computer having a feedback function that issues a correction signal to the operation of the solenoid valve confirmation and tally of the operation of a coating gun module is performed even when away from a production line.
