摘要： PROBLEM TO BE SOLVED: To provide a coating device improved in the working efficiency of a coating robot regardless of the quantity of the production by solving problems that the ratio of the non-working time such as the color changing in the coating robot is increased to decrease the working efficiency when the quantity of production is decreased, for example, in a coating line of a body for automobile, in which conventionally many robots are provided on the assumption that a work is moved at a high speed corresponding to the maximum production. SOLUTION: Plural coating moduli A and B each having a same coating process are arranged in parallel, the production capacity of each of the coating moduli A and B is set for small production and the production capacity is increased by simultaneously operating the plural coating moduli A, B and is decreased by stopping, the coating modulus B. As a result, the number of the coating robots 11, 21 in each of the coating moduli A and B enables to be decreased to increase the working efficiency of the robots.

摘要： PURPOSE:To improve productivity and coating finish in the coating of automobile body, etc., by specifying the axial central direction of air atomization coating guns, injecting a coating material from the one gun and air or coating material from another gun and acting both on each other during flying, thereby lowering the collision speed against a material to be coated. CONSTITUTION:The axial centers 111,112 of the air atomization coating guns (hereafter described simply as the 'guns') 11, 12 are respectively set at 0 to 30 deg. disposition angle A, B with a perpendicular 71 on the coating surface of the material 7 to be coated. The metallic coating material 6 is injected from the gun 11 and only the air 5 from the gun 12, respectively under the same injection pressure. Pigments 61 under flying toward the material 7 to be coated receive the interference of the reflected air 51 which is injected by the gun 12 and is reflected by the material 7 to be coated to lower the collision speed thereof. As a result, the orientability of the pigments 61 on the coating surface are randomized and the coating free from lightness differences and color tone differences is attained.

摘要： PURPOSE: To obtain a coating without deteriorating the smoothness of the coated surface close to the parting part between a first color coating range and a second color coating range in the coating of a car in two tones. CONSTITUTION: A car is coated in two tones with first-color and second-color paints by spray coating. In this case, a dilution solvent mixed with the first-color paint is sprayed on the part 21 along the parting line 3 between the first-color coating range 1 and the second-color coating range 2 on the second-color coating range 2 side in the first stage. The first-color coating range 1 is coated with the first-color paint in the second stage. At this time, the dust of the first-color paint scattered beyond the parting line 3 and deposited on the second-color coating range 2 is dissolved in the dilution solvent sprayed in the first stage. The coated first-color coating range 1 is masked in the third stage, and the second-color coating range 2 is coated with the second-color paint.
