<p>The amount of a coating material discharged to the outside of a coating material supply route in an air bleeding process is reduced. A coating material charging device (10) has a cartridge installation section (12), the coating material supply route (70), a trigger valve (72), a coating material supply device (20), a discharge route (76), a selection device (48), a coating material sensor (42), and a controller (80). The coating material supply route (70) communicates with a coating material cartridge (1) installed on the cartridge installation section (12). The coating material supply device (20) sends the coating material to the coating material supply path (70). The trigger valve (72) changes between communication and disconnection between the coating material supply route (70) and the coating material cartridge (1). The discharge route (76) communicates with the coating material supply route (70). The coating material sensor (42) detects the coating material in the discharge route (76). The controller (80) is connected to the coating material sensor (42) and the selection device (48). When the coating material sensor (42) detects the coating material, the controller (80) causes the selection device (48) to totally close the discharge route.</p> |
