Abstract: A color changer includes a valve module with a first interaction area and a plurality of valves. The valves are connected on their respective inlet side to a respective supply duct and are connected on their respective outlet side to a common collecting duct. The valves are openable and closeable via respective switches by a first actuation end discharging into the first interaction area. The color changer includes a switching module with a second interaction area and one actuator, which discharges by a second actuation end into the second interaction area. The valve and switching modules are arranged with their respective interaction areas adjacent and are displaceable relative to one another. Due to a respective displacement movement, the second actuation end is simultaneously movable with respect to at most one of the first actuation ends into a respective actuation position so that the actuator opens or closes the corresponding valve.

Abstract: A color-changer includes an output-channel having an outlet for paint material, and paint-supply-channels leading to the output-channel. The paint-supply channels are each respectively switchable by a corresponding first valve component. The first valve components are pilotable by a pressured fluid which is conducted through a corresponding pressure-line each having a corresponding inlet. One common, switchable pressure-supply-outlet is alternatively connectable with one of the inlets of the pressure-lines so that at most one of the corresponding first valve components is switchable at the same time. The present disclosure also provides a method for determining the leakage of the first valve component of the color-changer.

Abstract: A painting system having a painting robot with a stationary base mounted to a wall of a paint booth in cantilever fashion. A stand is mounted to the stationary base and is rotatable around a first axis that is disposed substantially horizontal. A first arm is rotatably mounted to the stand around a second axis, and a second arm is rotatably mounted to the first arm around a third axis. The second arm is operable to rotate around the third axis 180 degrees relative to the first arm. An end effector is connected between the second arm and a painting tool. The end effector is operable to orient the painting tool.

Abstract: A method for controlling a painting system including an industrial robot or manipulator arm arranged with a wrist section and carrying a paint applicator arranged on the robot wrist is described. Paint is applied by the applicator to a substantially circular or elliptical area on the surface, the center of the area being defined as a Tool Center Point. The wrist section is arranged capable of moving and orienting the paint applicator. In the method, the paint applicator is moved by the manipulator arm so that the Tool Center Point moves along a planned path so coating a part of the surface. The planned path may include one or more bends. The path taken by the robot wrist may be controlled to follow a different path from the path taken by the Tool Center Point. A system and a computer program for carrying out the method are also described.
