ABSTRACT:
An automatic painting device wherein control for driving spray gun heads in a Z axis direction is executed correctly with respect to a surface to be painted having a curved shape so that painting can be effected while keeping a constant interval between the plurality of spray gun heads and the surface to be painted. The automatic painting device can include a spray gun head unit holding a plurality of spray gun heads, an X axis direction driving mechanism for driving the spray gun head unit in a horizontal X axis direction, and a Y axis direction driving mechanism for driving the spray gun head unit in a Y axis direction perpendicular thereto, and in which different paints are ejected by the plurality of spray gun heads. The different spray gun heads are held by the spray gun head unit movably in a Z axis direction perpendicular to the x axis direction and the Y axis direction, independently from each other. The automatic painting device includes Z axis direction driving motors, which drive the spray gun heads in the Z axis direction, independently from each other on the basis of measured data and set data relating to a distance between a relevant spray gun head and an object to be painted. In this way the distance between the different spray gun heads and the surface to be painted constant can be kept constant, which improves remarkably the image quality of painting.
