Abstract: A coating material application system 1 includes: a support base 4 configured to rotatably support a coil spring W; a sensor 5 configured to measure a position of a strand of the coil spring W; a first movement device 6 configured to move the sensor 5; an application device 7; a second movement device 8 configured to move the application device 7; and a control device 3. The control device 3 includes: a support base control unit 331 configured to rotate the support base 4; a sensor control unit 332 configured to acquire a measurement value of the sensor 5; a first movement control unit 333 configured to move the sensor 5; a position-of-application calculation unit 334 configured to calculate, based on a measurement value of the sensor 5, a position of application of a coating material to the coil spring W; a second movement control unit 335 configured to move the application device 7 to a position where the application device 7 is caused to apply the coating material to the position of application; and an application device control unit 336 configured to cause the application device 7 to apply the coating material to the position of application.
