Definitions

  • the invention relates to a device for wet paint spray painting objects with a device for collecting the excess paint, which has an air-permeable dry filter.
  • the object of the invention is to provide an environmentally compatible and inexpensive device for wet spray painting objects.
  • this is achieved in a device of the type mentioned at the outset in that the dry filter is arranged to be movable and a suction device is provided, which during a certain period Vacuum dried up paint particles from the dry filter.
  • the invention is based on the knowledge that it is not necessary to wash off the excess paint collected by the filter with liquid solvent in a wet separation process during wet paint spray painting, but rather that it is sufficient to suck off the excess paint from the dry filter after a certain drying distance so that it is not thrown away must become.
  • Vacuuming filters has long been known in powder coating systems. In such systems, a powder, for example electrostatically, is applied to the objects to be coated and the excess powder is suctioned off (for example DE 28 13 854 C2).
  • the invention relates to another genre, namely wet paint spray painting with liquid media.
  • the suction device is arranged at a location which is distant from the area in which the dry filter absorbs the excess paint, because then the paint particles have enough time to dry completely and are therefore easy to extract even when the dry filter is moved continuously to be.
  • 1 shows a top view of an exemplary embodiment of a device according to the invention for manual wet paint spray painting of objects
  • 2a shows an embodiment of a dry filter according to the invention in cross section
  • 2b shows a bottom view
  • 3 shows a deflection drum for the dry filter movable according to the invention
  • 4 shows a further embodiment of a device according to the invention for collecting excess paint in a front view
  • 5 shows an embodiment for a spray painting of a car
  • 6 shows a perspective schematic view of an embodiment of a suction device with a suction nozzle that can be moved transversely to the dry filter.
  • FIG. 1 shows a device for the wet paint spray painting of objects 1 by means of a manually operated spray gun 2, which for example has a container for liquid paint and is connected to a compressed air line 3.
  • An air-permeable dry filter 4 is provided according to the invention to catch the excess paint that passes past the object 1 and is arranged so as to be movable over deflection drums 5.
  • a suction device 6 is also provided, the suction opening 7 of which lies at a point as far away as possible from the area 8 in the direction of movement of the dry filter 4, in which the Dry filter absorbs excess paint.
  • An exhaust air duct 9 of an exhaust air system is connected between the front run and the rear run of the endlessly circulating dry filter, which sucks air out of the exhaust air duct 9.
  • This exhaust air duct 9 is perforated or air-permeable at the point 10 so that the exhaust air passing through the dry filter 4 can enter the exhaust air duct 9.
  • the paint particles are collected by the dry filter 4 and later sucked off by the suction device 6. This makes it possible to continuously clean the dry filter 4.
  • the dry filter can be moved continuously. However, discontinuous movement is also possible, for example in a separate cleaning run in the evening.
  • the dry filter 4 is advantageously formed in two parts, namely from an air-permeable, statically stable but nevertheless flexible carrier 4a and the actual dry filter material 4b.
  • the filter material is preferably a fleece, advantageously a polyester fleece or glass fiber fleece, which typically has a height of a few centimeters.
  • the carrier 4a can be provided with holes 11, as shown in the bottom view of FIG. 2b.
  • the carrier advantageously consists of material to be conveyed, for example fiber-reinforced rubber. It is also possible to form the carrier 4a from an air-permeable fabric (that is to say without discrete holes 11).
  • two guide projections 12 are formed on the rear side of the dry filter 4 in the exemplary embodiment in FIGS. 2a, 2b. These guide projections 12 can then be guided in corresponding guide grooves (not shown) in the deflection rollers 5 and then guide the rotating dry filter 4 in the transverse direction.
  • the carrier 4a has at least one row of holes 13 into which pins 14 engage, which are arranged on the guide roller 5 designed as a drive wheel.
  • the drive wheel 5 is driven by an overlying electric motor 15, possibly via a gear, not shown.
  • the electric motor 15 is controlled by a control device 16.
  • the dry filter 4 also rotates in the horizontal direction.
  • the guidance in the vertical direction takes place in that the dry filter 4 has guide elements 17 at the top, which are guided in a stationary horizontal guide rail 18 (similar to a curtain rail).
  • the guide rail 18 can be guided endlessly over the entire circumference above the dry filter.
  • this guide rail 18 it is also possible to arrange this guide rail 18 only in the front area and in the rear area and to achieve vertical guidance in the area of the deflection rollers 5 by other means, for example by the pins 14 engaging in the rows of holes 13.
  • FIG. 5 shows a device for spray painting a car 19.
  • the dry filter 4 is aligned horizontally and runs below the spray booth 20.
  • the suction opening 7 of the suction device is moved transversely to the direction of movement 21 of the dry filter 4.
  • This has the advantage that a small suction nozzle 6a with high local suction power can be used to suck the dried paint particles from the dry filter 4.
  • the suction nozzle 6a is connected to the suction unit 6c of the suction device via a flexible hose 6b.
  • the movement of the suction nozzle 6a in the vertical direction in FIG. 6 preferably takes place via a motor drive (not shown), for example via a cable drive, a spindle drive, a rack drive or the like.
  • a device 23 for mechanical tapping on the dry filter 4 on the rear side (side of the carrier 4a) of the conveyor belt 4, in order to be able to better detach the paint particles from the latter.
  • This device 23 can also be used to generate an air flow which is directed from the rear of the dry filter 4 to the front and thus supports the suction air movement.
