Definitions

  • the present invention relates to a device for cleaning objects which have come into contact with paint, in particular to a cleaning system for paint spray guns and paint containers.
  • Pneumatically operated paint spray guns have been known for a long time. These usually consist of the actual spray gun and an associated paint container, which is used to hold paint. There are three known variants of spray guns; in two of these known embodiments the paint container is located below, in the third known embodiment above the nozzle.
  • paint residues remain in the paint container and in the various parts of the spray gun, for example in the pipes and in the nozzle itself, but also on the outer jacket of the spray gun and the paint container.
  • the invention is therefore based on the object to provide a device which ensures thorough and automatic cleaning of the gun, the paint container and any paint mixing container from the inside and outside reliably, quickly and inexpensively.
  • An object of the invention is to use the device to convey the solvent under pressure into the interior of the spray gun, the paint container and / or the mixing container, while at the same time cleaning the outer casing of the spray gun and the container or containers.
  • Another object of the invention is to ensure a constant flow of the solvent to the individual parts to be cleaned.
  • the invention is intended to ensure that the liquid or dried paint which has been removed from the gun and the other objects is collected separately from the solvent and outside the working chamber in which the objects to be cleaned are located.
  • Another object of the invention is to provide a cleaning device with three different sections: a solvent reservoir, a reservoir in which the detached paint is collected and from which it is later removed, and a working chamber in which, separated from the other two sections, the items to be cleaned are stored.
  • such a device for removing paint consists of a closed housing which is divided into a working chamber and a liquid collection tank; the liquid collection tank holds the color solvent and another liquid that has a higher specific gravity than the solvent. Due to the higher specific weight of the paint compared to the solvent, it is deposited in the heavy liquid under the solvent. This results in a certain reprocessing of the solvent.
  • the device also has a spray device, wherein first, second and further outlets are provided, which are supplied with pressurized solvent.
  • the first outlet has both means for receiving and holding a spray gun, as well as means for causing the interior of the gun to flow through with solvent.
  • the device has a plane for receiving objects that are cleaned in a preferred position relative to the second opening, and a device for conveying the solvent from the reservoir or storage container to the spraying device.
  • the device also has further spray nozzles, which serve to remove paint from the surface of the objects to be cleaned. Furthermore, a carrier is provided which serves to rotate an ink container relative to the respective outlet; this ensures that the paint container can be cleaned from all sides. In addition, a locking means for the trigger of the spray gun is provided to hold the trigger in the working position, so that a continuous spraying is ensured.
  • FIG. 1 shows the cleaning and reprocessing device 10 according to the invention, which has a housing 12 with an essentially rectangular upper part 14.
  • the part 14 has at its lower end a circumferential shoulder 16, which is adjoined at the bottom by a lower part 18 designed as a rectangular cone, which ends with a bottom 20.
  • a drain valve 22 In the bottom 20 there is a drain valve 22.
  • the chamber 12 is held by several supports 24a-d, an upper support frame 26 and a further circumferential support frame 28 on which the shoulder 16 of the upper part 14 is supported.
  • the frame 26 also has a stiffening function for the housing 12, especially when the housing is made of plastic.
  • a hinged cover 32 which rests on a peripheral edge 27 of the housing 12.
  • a pump 40 is arranged on one of the supports 24a-d.
  • This pump can be an air-operated pump, for example.
  • the pump 40 has an inlet pipe 42, the filter-provided end of which extends into the solvent in the lower part 18, and an outlet pipe 44, which is located above the surface of the solvent 36.
  • the outlet pipe 44 is connected to the spray device 52, which is shown in detail in FIG. 2.
  • the pump 40 also has an inlet opening for compressed air.
  • Fig. 2 shown as a section through the housing 12, shows many of the essential features of the present invention.
  • a mesh fabric preferably a wire mesh 50, which rests on the circumferential shoulder 16 of the housing 12.
  • a working chamber 72 is divided from the housing 12, below which the lower part 12, which is designed as a rectangular cone and in which the solvent 36 and the water 34 are located, is arranged.
  • the objects to be cleaned lie on the surface formed by the wire mesh 50.
  • the spray device 52 which consists of a holder 54 which is fastened to the lower part 18 by means of supports 55 or equivalent means.
