Abstract: A spray-gun line-connecting device is provided for the connection of a plurality of lines between a robotic arm and a spray device. The spray-gun line-connecting device may provide a plurality of cylindrical connection joints at an interface between mating surfaces. For example, the lines may include enlarged cylindrical heads, which fit within cylindrical receptacles in a first mating surface. A second mating surface may extend over the first mating surface, and include passages aligned with the lines.

Abstract: In an automatic spraying device for coating liquids, which can be attached to a robot for spray-coating objects, the longitudinal axis of the spray nozzle defines a straight center line of the device. The flange surface of a device flange extends transversally to the device center line and can be attached to a robot flange. A tube connection device on the rear side of the spray device is designed in such a manner that all tubes which are necessary for supplying the spray device with liquid or gaseous fluids extend parallel to the device center line from the rear side of the spray device towards the rear into the robot flange. The spray device is preferably constructed in a modular manner.
