Definitions

  • the invention relates to a device for spray treatment, in particular for spray painting objects with a precipitation surface extending transversely to the spray direction for the spray medium passing past the objects, with at least one scraper for removing the precipitation from the precipitation surface and a collecting trough arranged below the precipitation surface.
  • the precipitation surface for the spray medium passing by the objects to be treated is moved while the scraper is arranged in a stationary manner.
  • a moving precipitation surface can be, for example, a rotating disk or a moving belt, each of which is guided along one or more scrapers.
  • the rotating disk on the other hand, has a support device in the area of the scraper, which is intended to protect the axis of the disk from bending and breakage.
  • the bending stress on the axle is reduced by the fact that the washer is pressed against the support device by the scraper.
  • the moving belt is a link belt which has joints between each individual link, which are moved past the wipers and thereby subject the wiper to particularly high mechanical stresses. This stress causes the scraper to wear out quickly and become unusable.
  • the invention has for its object to provide a generic device that allows enough large pressure forces between the wiper and the precipitation surface, but still does not require a lot of energy to overcome the friction and for driving moving masses, and is characterized by low susceptibility to interference.
  • the precipitation area is formed on a stationary wall and the scraper is arranged to be movable over the precipitation area.
  • a precipitation surface arranged on a stationary wall can be built up in a correspondingly stable manner so that it withstands the necessary pressure forces to be applied to the precipitation surface by the scraper.
  • a particularly expedient embodiment of this device results from a further innovative feature if endless chains or the like are guided along two parallel side edges of the stationary wall via deflection rollers, to which the stripper is attached in a preferably rectangular arrangement to the chain strands or the like.
  • the two endless chains and the scraper have a very small mass compared to the moving parts of the known device for recovering the overspray, so that a cheap motor with low power can be used.
  • the stripper can be moved in the downward direction over the precipitation surface, which ensures that areas of the precipitation surface that have already been cleaned are not hit by paint residues dripping from the stripper.
  • the scraper has at least one flexible slide lip which extends over the entire width of the precipitation area, so that the entire precipitation area is cleaned when the scraper moves downward.
  • a spray device or the like for solvents is arranged along the upper edge of the wall, the spray nozzles of the spray device being aligned with the upper region of the precipitation surface.
  • the solvent applied to the precipitation surface from the spray device counteracts the solvent loss of the overspray caused by evaporation and keeps the overspray liquid, so that a clean wiping of the overspray from the precipitation surface is ensured.
  • FIG. 1 An object 1 to be coated can be seen in FIG. 1.
  • the object 1 is acted upon by a spray medium 2.
  • the spray medium 2 emerges from a spray device 3, which is arranged so that it can be moved up and down on a stationary stand 4.
  • a wall 6 provided with the precipitation surface 5 is arranged in a stationary manner (see also FIG. 2).
  • Two endless chains 8 are placed around deflection rollers 7.
  • Two deflecting rollers lying on one axis are driven by an adjustable motor M.
  • two wipers 9 are arranged at right angles to the chains 8.
  • the wipers 9 are firmly connected to the chains 8.
  • a guide is provided, into which the wipers 9, which move downward, run.
  • a profile 9 'connected to the wall 6 is used as a guide.
  • the slide lip 10 is located on the wipers 9.
  • the slide lip 10 serves to remove the spray medium 2 passing the object 1 to be coated from the precipitation surface 5. So that the so-called overspray always remains liquid and can be stripped from the precipitation surface 5 by means of the slide lips 10, solvent 12 is applied in the upper part of the precipitation surface 5 by a spray device 11. The solvent runs along the precipitation surface 5, thus compensating for the solvent losses in the overspray, and keeps the overspray liquid.
  • a spray system 14 ensures good mixing of the solid components of the spray medium 2 with the solvent.
  • the spray system 14 is designed to be pivotable. This makes it possible for the collecting trough 13, in the swung-out state of the spray system 14, to be removed from the supporting and loosely holding container 15.
  • Fig. Shows how the collecting tray 13 filled with a color is exchanged for an empty tray. It is also possible to replace the tub 13 with a tub filled with a different color.
