Definitions

  • the invention relates to a method and a device for coating parts according to the preambles of the claims 1 and 4.
  • Methods and devices of the above Kind are z. B. from US-PS NO 4,311,724 known.
  • a Color change e.g. B. when painting the body one Motor vehicle, detergent and / or compressed air is in the given the paint to the line leading to the atomizer, so that at least parts of the residual paint are recycled can.
  • this method can be used in many cases do not carry out because the detergent or compressed air not physically separated as it would be required behind the paint column to be pushed out the feed line move, but when flowing through Mix with the paint material inside the atomizer. An exact determination of the still usable, in amount of paint in the feed line is therefore impossible so that for security reasons most of it the residual paint must be removed and disposed of unused.
  • the invention is therefore based on the object of measures provide a reliable separation between the coating agent still to be used and one this pushing means from the feed line can be achieved.
  • the invention provides the features of the characterizing part of claim 1 before that a separating element between the completion of the painting process the rest of the paint and the pushing agent into the feed line is introduced and that the separating element then before reaching of the atomizer removed from the feed line again becomes.
  • the device for performing this method comprises a color changer and an atomizer at the ends of one Feed line and provides according to the invention that the separating element in the supply line between a parking station and a collecting station is movable.
  • the separating element is in entered the feed line until it was in the collecting station arrives. There the separator is stopped while the Pushing means e.g. B. flows around the separating element and continues to flow to the atomizer to z. B. to clean.
  • the separating element is also made using detergent pressed from the rescue station back into the parking station and then there with the help of an adjustable Holding element fixed.
  • the invention is described below using an exemplary embodiment, which is shown in the single drawing described.
  • the drawing shows essentially a flow chart and only those parts and components, those immediately required to carry out the procedure are. It is understood that other components for Completion of a complete coating or painting system necessary and common and generally known are. These components are in the single drawing also not shown for reasons of clarity.
  • a device 1 for coating or painting comprises a color changer 2 according to the embodiment several lines 3, 4, 5 and 6 for different colors to lead.
  • Each of the lines 3 to 6 also belongs a control valve 7, the lines 3 to 6 optionally with a feed line 8 connects.
  • At the other end 9 of the feed line 8 is an atomizer 10 for the coating agent or arranged for the paint.
  • the feed line 8 In the area of the color changer 2 are on the feed line 8 also a detergent line 11 with check valve and Control valve and a compressed air line 12 with a check valve and control valve connected as the only figure shows.
  • the meter should change color also the coating material located in the feed line 8 or the paint located there in such a way be used as much as possible.
  • This is located directly at the outlet 13 of the feed line 8 from the color changer 2 a parking station 14 for a separating element 15, the before the end of the following basically only as Painting process called coating process in the Feed line 8 is inserted to ensure safe separation between paint and one to transport this To ensure residual paint serving sliding medium.
  • Sliding medium can either detergent from the detergent line 11 or compressed air from the compressed air line 12 serve after the respective associated valves accordingly have been switched.
  • the paint and the sliding medium the separating element 15 easily in the direction of the atomizer 10 flow around.
  • the separating element 15 moves through the feed line 8, until it reaches a collecting station 18.
  • the sanctuary 18 also has a chamber 19, the clear cross section is larger than the clear cross section of the feed line 8.
  • the clear cross-section of the Collection station 18 to the atomizer 10 leading piece 20 of the feed line 8 is less than the cross section of the Separating element 17, so that the separating element 17 is not in the Line piece 20 can occur.
  • Stop can be provided in the collecting station 18, to prevent the separating element 17 from moving further into Can move towards atomizer 10.
  • a device 21 Located behind the collecting station 15 in the direction of flow a device 21 with control valves 22 and Check valves 23 for a detergent line 24 or for a compressed air line 25.
  • control valves 22 detergent or compressed air can do more than just that Feed line 8 and all lying in the direction of flow Clean or apply components, but also that Separating element 15 can be used again in the Move back parking station 14 until there is a further movement in the direction of color changer 4 by a stop 26 is prevented.
  • a metering device 27 Located between the device 21 and the atomizer 10 finally a metering device 27 to the a bypass line 28 out with a control valve 29 is.
  • sensors 30 are arranged at the end of the feed line 8 be the separating element 15 during its movement detect and send a signal to the controller of the Give device 1.
  • the separating element 15th In order to ensure that the sensors 30 the separating element 15th also record reliably, expediently contains this a metallic core.
  • the separating element 15 largely dimensionally stable and can have sealing lips, to achieve the desired tightness.
  • the separator is therefore a relatively short, solid body that fits positively into the feed line 8. That body is largely dimensionally stable and represents a third element represents that as a separating element 14 between the paint and the Sliding or printing medium is arranged. Because of his Dimensional stability is able to transition the Prevent sliding medium in the residual paint.
