ABSTRACT:
A paint spray system includes a spray gun for ejecting paint toward work pieces carried in a generally horizontal direction by a conveyor chain. A pneumatic actuator moves the spray gun in a generally vertical direction as paint is ejected from the spray gun. The pneumatic actuator includes a casing, a piston disposed in the casing for reciprocating movement therein, and a load plate connected to the piston for carrying the spray gun. The piston defines an upper chamber and a lower chamber in the casing. When compressed air is delivered into the upper chamber, the piston and the load plate are moved in a downward direction. When compressed air is delivered into the lower chamber, the piston and the load plate are moved in an upward direction.
