Automatic painting system

摘要

An automatic painting system has a painting booth composed of a partition having side walls, a ceiling, and a floor which jointly define a working space isolated by the partition from exterior space for accommodating a workpiece to be painted in a position therein. The partition has air inlet and outlet ports opening into the working space. A movable painting mechanism such as a robot paint spray gun is disposed adjacent to the workpiece position and controlled by a control unit disposed outside of the painting booth and including a robot drive source. The control unit and the movable painting mechanism are interconnected by an arm accommodated in an arm housing extending through the partition with a sealing member hermetically sealing a gap between the arm housing and the partition. A door is mounted on the partition in the vicinity of the workpiece position for transfer of the workpiece into and out of the painting booth.
