Patent number: 9427771Abstract: An orbiting scroll is fixed on a rotating table and rotated about a spiral center. A spray nozzle is positioned in the spiral center or at an outside end of the orbiting scroll and caused to discharge a coating toward a side face of a wrap portion. The spray nozzle is moved along a straight line in a radial direction while discharging the coating. When a spraying start position is set as the spiral center, a rotation angle speed of the orbiting scroll is gradually reduced in accordance with the movement of the spray nozzle. When the spraying start point is set as the outside end, the rotation angle speed of the orbiting scroll is gradually increased in accordance with the movement of the spray nozzle. As a result, the coating can be applied to the wrap portion side face evenly.Type: GrantFiled: July 12, 2013Date of Patent: August 30, 2016Assignee: ANEST IWATA CORPORATIONInventors: Junichi Asami, Tatsuya Minegishi, Tohru Kuwata
