COATING APPARATUS AND COATING METHOD

摘要

To improve actual coating efficiency, the present invention has a coating robot provided with a coating unit configured by a plurality of rotary atomizing type electrostatic coating machines horizontally arranged, and a coating control apparatus that controls the coating unit and the coating robot. A diameter of each of bells is 50 mm or less. The coating material discharge amount of each rotary atomizing type electrostatic coating machine is 400 cc/min or less. A coating distance between each bell and a surface to be coated of a workpiece is controlled between 50 mm to 150 mm. The coating material discharge amounts of the plurality of electrostatic coating machines are controlled for the respective coating machines. The control of the coating material discharge amounts includes a pause of coating material discharge.

主权项

1. A coating apparatus comprising:
a coating unit configured by a plurality of rotary atomizing type electrostatic coating machines disposed adjacent to each other; a coating manipulator on which the coating unit is mounted; and a coating control apparatus that controls the coating unit and the coating manipulator, wherein a diameter of an atomizing head of each of the rotary atomizing type electrostatic coating machines is 50 mm or less, wherein a coating material discharge amount of each of the rotary atomizing type electrostatic coating machines is 400 cc/min or less, wherein the coating control apparatus controls the coating unit to keep the atomizing head within a coating distance between 50 mm to 150 mm from a surface to be coated of a workpiece, wherein the coating control apparatus controls the coating material discharge amounts of the plurality of rotary atomizing type electrostatic coating machines independently from one another thereof, and wherein the control of the coating material discharge amounts of the respective rotary atomizing type electrostatic coating machines includes a pause of coating material discharge from the rotary atomizing type electrostatic coating machines.
