SURFACE COATING APPARATUS AND SURFACE COATING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a coating apparatus and method in which the re-deposition of a sprayed coating material and the soiling by the sprayed coating material on the surface of a coated processed product are suppressed. SOLUTION: The coating apparatus 1 has a coating nozzle 2 for applying the coating material on the surface of the processed product 3 and a suction apparatus for sucking coating material vapor and/or air containing the sprayed coating material. The coating nozzle 2 and the processed product 3 are relatively moved. A suction bell 4 arranged to cover an opening part 9 of the coating nozzle 2 is firmly connected to a nozzle wall 14 of the spray nozzle 2. The suction bell 4 is constituted so as to include an inner bell 5 and an outer bell 6 and is arranged with a slight distance from the processed good 3. The outer bell 6 is arranged to cover the inner bell 5 to keep a separated state from the inner bell 5. The inner bell 5 forms a spray chamber 7 and a suction chamber 8 having a suction port 10 between the outer bell 6 and the inner bell 5 is formed by the outer bell 6 and the inner bell 5.
