Abstract
A paint spray apparatus includes a plurality of paint sprayers installed in a paint spray booth. Each paint sprayer includes a paint spray head pivotably mounted on the end of a movable paint spray arm. The paint spray arm and paint spray head are movable on multiple axes by servo motors, which are controlled by servo drives mounted on or beside the paint sprayer. The spray of the paint spray head is controlled by a plurality of proportional solenoid valves mounted on the paint sprayer. The movement and spray of the paint sprayers are controlled by a computer having an interface to an optical fiber. The optical fiber connects the computer to the servo drives in series in a token ring network.
