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.
