Robot Changing System: One robot operates several spray guns

The new Robot Changing System KRWS from Krautzberger GmbH enables automatic coating and painting of parts with different spray patterns and spray gun extensions, as well as easy change of fluids and colors.

How it works: The various RWA1 automatic spray guns are located and precisely positioned in a changing/docking station. The robot, which is equipped with a quick-change system for the spray guns and controlled by the main control system, picks up the required spray gun from this changing station and sprays the respective coating onto the part. The spray guns can be supplied with fluid either by directly attached cups (for small quantities), external pressure tanks or pumps. In the case of external fluid supply, there is the possibility of a circulation system.
With this system, different spray guns can be operated with a wide range of configurations (nozzle/needle sizes, air caps, nozzle extension options). Since a robot allows multiple media changes, this system allows complete coating of even complex parts. It is also very suitable for small batch production and for very small amounts of paint (when the material hopper is mounted directly on the gun).
