ことを課題とする。In the above known technique, the supply time of the pressurized fluid (adhesive) is changed by changing the swing angle or the swing center of the cylindrical valve body. Therefore, although it is possible to increase or decrease the supply time in the position swing stroke and change the ratio of the supply time to the non-supply time, the shape of the groove of the cylindrical valve body (angle range where the groove exists in side view) ) And the structure of the swing center angle setting means, there is a problem that the coating timing (coating start position and coating end position) cannot be set regardless of the coating length (coating section). Also, by controlling the opening and closing of solenoid valves by microcomputer control, the supply cutoff of adhesives, paints, and other coating agents is controlled, and the timing for starting and ending the supply of coating agents is set, thereby selecting the coating position and coating length. Although it is possible to make it freely, there is a problem that if the solenoid valve is opened and closed at a high speed of a certain speed or higher, it is impossible to cut off the supply due to a chattering phenomenon. Therefore, it is an object of the present invention to provide a coating device capable of performing supply control at high speed and at arbitrary coating timing.
