Abstract
A workpiece 1 is supported on a conveyor 2 through a carrier 3. A supporting portion of the workpiece 1 is vertically and horizontally rotatable to change its position to a floor conveyor position, an overhead conveyor position, and a side conveyor position. The workpiece 1 is first moved to enter a spray booth 30 in the floor conveyor position ({circle around (1)}) and then vertically rotated to the overhead conveyor position where the bottom portion thereof faces upward. An under-side coating is performed on the lower portion of a car body by a spray apparatus 31 for which the nozzle position is situated lower ({circle around (2)}). The workpiece 1 is then horizontally rotated to the side conveyor position where the left-hand side of the car body faces upward and an L-side coating is performed on the left-hand side of the car body by the same spray apparatus 31 as above ({circle around (3)}). Subsequently, the workpiece 1 in the side conveyor position is vertically rotated 180° to the side conveyor position where the right-hand side of the car body faces upward and an R-side coating is performed on the right-hand side of the car body by a spray apparatus 32 for which the nozz…
