Definitions

  • the present invention refers to an improved washing device for a spray gun with a gravity bowl.
  • a spray gun mixes compressed air with a paint fed from a container, or bowl to be precise, through gravity.
  • the jet of compressed air allows nebulized paint to be sprayed externally.
  • the airflow is controlled by a lever on a grip on the gun.
  • the post-use washing step is particularly important, in order to ensure optimal operation the next time they are used.
  • a known technique which is currently widely used is that of using a washing device comprising a tank, equipped with a cover, in which the gun to be washed is placed.
  • a washing device comprising a tank, equipped with a cover, in which the gun to be washed is placed.
  • nozzles are foreseen which spray washing liquid from all sides of the gun itself.
  • conical nozzles the flow of which is directed upwards.
  • the spray gun is positioned upside down and a washing nozzle is inserted in a paint supply channel which connects the gun with the gravity bowl.
  • a washing nozzle is inserted in a paint supply channel which connects the gun with the gravity bowl.
  • the gravity bowl is removed prior to the positioning of the gun in the washing device.
  • washing nozzle also acts as a support for the gun itself.
  • washing liquid normally used is a diluent: especially during spraying, it is an extremely volatile product, which generates polluting and flammable gases.
  • blowing air in such a channel involves continuous emission into the atmosphere of the harmful gases which form, with consequent problems of pollution and also of safety for the personnel carrying out the washing operations.
  • the general purpose of the present invention is that of overcoming the aforementioned drawbacks of the prior art and in particular is that of realising an improved washing device for a spray gun with a gravity bowl which allows effective cleaning of the gun itself without involving pollution of the environment.
  • Another purpose is that of realising an improved washing device for a spray gun with a gravity bowl in an extremely simple, cost-effective and particularly functional manner.
  • an improved washing device is wholly indicated with 10, and in the illustrated example, according to the present invention, comprises a washing tank 12 in which washing nozzles 14 are arranged.
  • the tank 12 has an opening, able to be closed with a closing element 16. Through such an opening a spray gun 20, represented in section in figure 1, is entered into the tank 12.
  • the spray gun 20 has at least one paint supply channel 22, which connects it to a gravity bowl, not shown in the figures, which is arranged above the gun 20 itself and where paint is poured to be sprayed.
  • the paint supply channel 22 terminates in a front zone of the gun 20. Still in such a front zone at least one compressed air channel 24 terminates.
  • Such a channel 24 crosses the gun 20, terminating at a base of a grip 26 of the gun 20.
  • the compressed air channel 24 is L-shaped.
  • FIG 2 it can be seen how inside the tank 12 a support 18 for the gun 20 is foreseen, which is arranged in a position similar to that taken up during spraying operations, i.e. with a paint supply hole facing upwards and with a compressed air entry hole facing downwards.
  • washing liquid is sprayed in the paint supply channel 22, through insertion of a further washing nozzle 15, for example having a conical end.
  • a portion of the piping 19 comprises flexible piping 17, suitable for allowing easy insertion of the further washing nozzle 15, arranged for example at one end of the piping 19, in the paint supply channel 22.
  • washing device 10 The operation of the washing device 10 according to the invention is clear from that which has been described above with reference to figures 1 and 2, and in brief is the following.
  • the trigger 27 of the gun is pulled and held, through a catch 28, in pulled position, so as to keep the free end of the paint channel 22 open.
  • the tank 12 After having positioned the gun 20 (with the trigger 27 pulled) on the support 18 and after having inserted the further washing nozzle 15 in the paint supply channel 22, the tank 12 is closed with the closing element 16.
  • the washing liquid is introduced into the piping 19.
  • the piping 19 feeds the washing nozzles 14 and the further nozzle 15.
  • the latter manages to wash the paint supply channel 22 extremely well, whereas the washing liquid does not enter into the compressed air channel 24 through gravity, since the vertex of the "L" of channel 24 itself faces upwards.
  • FIG 3 illustrates a further possible practical embodiment of the invention, where the components which are the same as/equivalent to those illustrated in figures 1 and 2 carry the same reference numerals increased by 100.
  • An improved washing device is wholly indicated with 110, and comprises a washing tank 112 in which washing nozzles 114 are arranged.
  • the tank 112 has an opening, which can be closed with a closing element 116. Through such an opening a spray gun 120 is introduced into the tank 112.
  • a support like the support 18 of figure 2 is not foreseen, since the gun 120 is arranged, still in a position like the one taken up during spraying operations, through for example insertion with interference of a conical end of the further washing nozzle 115 in the paint supply channel 122.
  • washing device 110 The operation of the washing device 110 according to the invention is clear from that which has been described above and is totally analogous to that of the washing device 10 of figure 2. Also in this position (totally similar to that of figure 2), the liquid does not enter into the air channel 24, thus avoiding the drawbacks of the prior art.
  • the shapes of the improved washing device for a spray gun with a gravity bowl of the invention can be different from the one shown only as a non-limiting example in the drawings, just as the materials can also be different.
