  • a requirement for pertinent paint shops It is often possible to change the type of paint (metallic paints) and / or the color accordingly.
  • Modern paint shops are therefore not only equipped with powerful color changing and dosing, but also with cleaning facilities that allow in a color or paint change the previously used in the delivery line medium (paint or paint) from the delivery line so in the reservoir from the medium comes back to bring back the delivery line of media residues in such a way that when using the new medium (lacquer or paint) it does not come to disturbances such that in an unintentional way the remainders of the previously used medium in turn on the respective workpiece surface (Car body part) can get.
  • a method according to the preamble of claim 1 is known for example from GB 2182266.
  • the state of the art provides solutions, for example painting systems (DE 199 37 474 C2) with a gun unit, with which paint can be applied to a workpiece, with a color changing device, to which at least two paint feeders are connected, with a connecting device, with which the gun unit and the color changing device are interconnected, with a pig station associated with the gun unit, with a color changing device associated pig station and a pig, which during a cleaning phase of the gun unit associated pig station through the connecting device into the color changer associated pig station and can be moved back again.

  • the method is operated in any case with the device side given components such that the cleaning medium does not accidentally reaches the reservoir side, but rather that here before a discharge from the delivery line takes place.
  • the method according to the invention does not need to be restricted to the application of painting systems, but is basically suitable for all types of media to be transported in a delivery line, which optionally lead to contamination in the delivery line or in the subsequently arranged delivery unit.
  • compressed air is used as the cleaning medium or, assisted by compressed air, the cleaning medium is transported in the conveying line.
  • the cleaning medium is preferably a solvent

  • the media volume is determined by means of a control device, in particular in the cleaning operation of the system, taking into account the pumping volume of the pumping unit and the number of their revolutions for controlled removal of the cleaning medium from the delivery line before reaching the control unit. Since the cleaning medium should not reach the supply side of the medium, it must be determined how much cleaning medium is transported in the delivery unit before it reaches the control unit to which the media supply side is connected.
  • the pump volume, the speed of the pump as well as the volume in the delivery line are taken into account. This serves the controlled return of the paint in the reservoir.
  • this ensures that the control unit blocks beforehand and the cleaning medium then leaves the actual application system with delivery line via a branch line which can be actuated via a further valve unit, wherein the pertinent media residues together with cleaning medium can be stored in a collecting container.
