PURPOSE:To perform the explosion-proofness of a robot, by always supplying cooled dry fresh water to the motor of an electromotive type painting robot and exhausting the same therefrom while monitoring the pressure of said air. CONSTITUTION:Cooled dry fresh air is always supplied to a motor unit through an air supply hose 34 also used as the cover hose of an electric wire cable 33 and exhausted from an air exhaust hose 35. A diaphragm 36 is reversed by pressure of fresh air itself to perform switching of a limit switch 37 but, when pressure is removed, the diaphragm 36 is reversed to the original state by a spring 38 and, therefore, air is monitored. By this mechanism, danger is eliminated and explosion is prevented. |
