摘要： A coating device has a coating head that dispenses coating material toward a vehicle body. The coating device also includes a supply device that has a circulation path for circulating the coating material between a reservoir storing the coating material and the coating head, and is capable of controlling the pressure of the coating material flowing through the circulation path. The coating device includes an arm having the coating head and the supply device, wherein the coating robot performs coating of the vehicle body while moving the coating head wherein the coating head moves at a first speed toward a coating start position to start coating the vehicle and moves at a second speed different from the first speed when it reaches a specific position in a movement path to the coating start position.
