Definitions

  • paint spray gun for applying paint
  • a paint can usually located on the paint gun
  • a type of compressed air supply By supplying compressed air, the paint is atomized and a spray applied to the point to be painted.
  • the supply of compressed air is usually via a compressor that works like a pressure pump and only generates compressed air when it is needed.
  • Compressors are also usually heavy equipment that can be brought to the site with great difficulty and require a constant power supply. For paint work inside an aircraft very strict rules apply, so internal parts of an aircraft are removed and painted outside and then reinstalled.
  • US 2010/122745 A1 describes a container for spray coating a human, the container comprising a body coating composition.
  • the container comprising a body coating composition.
  • the containers are connected to outside valves with internal valves in the spray device. Pumps may be present.
  • US 2007/272707 A1 describes an independent paint application equipment employable with refillable rollers or spray guns and comprising a portable tank having two separate storage chambers, one for the paint and the other for operating components such as a gas cylinder, engine and controls.
  • WO 2013/049260 A2 describes a liquid dispensing device comprising a bottle having an inner and an outer container filled with a liquid, a valve, and a portable dispenser having a detection zone and an activation zone. An external power supply is also available.
  • US 2001/030241 A1 describes a portable system for spraying viscous materials to form truck cargo liner liners.
  • Containers with the coating material and two pumps, which transport the coating material to a spray gun, are arranged in a portable handcart.
  • a compressor is also arranged on the trolley.
  • US 2006/120794 A1 describes a connector between a paint container and a paint dispenser that allows commercial containers to be used as part of a mobile fluid dispenser.
  • the connector has a lid for leak-free attachment to the container of viscous and semi-viscous liquids, with a tube extending from the interior of the container through the lid to a pump, and a flexible tube.
  • DE 10 2009 048022 A1 describes a portable paint sprayer comprising a base station with a drive unit and a tubular lance having a first channel for passing the paint and a second channel for passing the air flow, wherein the drive unit comprises a first working unit for generating an air flow, a second working unit for generating a Color stream and comprises a control unit, wherein the lance has an operating unit and a spray head, the lance is connected via an air line to the first working unit and the lance is connected via a paint line to the second working unit.
  • US 2008/061166 A1 describes a portable, self-propelled sprayer that produces a foam spout spray from a liquid.
  • the spray device comprises separate air and liquid delivery systems which separately introduce air and liquid into a mixing chamber.
  • a pump can be present.
  • the air supply system may include a compressor.
  • US 5 074 467 A describes a paint spraying system including a blower motor with a cooling fan, a high volume, low pressure blower fan driven by the blower motor, an air line connecting the blower motor outlet with a spray gun, and a valve in the spray gun.
  • the object of the invention is to provide a painting system which is easy to handle and portable.
  • a painting system constructed in this way is compact and can easily be carried by a person to the site.
  • the use in aircraft is preferred, since there are strict rules in terms of pressure vessel and power requirements in aircraft.
  • the on-board network in large passenger aircraft has a rated voltage of 115/200 V and 400 Hz. Therefore, commercial air compressors can not be used.
  • the entrainment of pressure vessels is also possible only after enormous bureaucratic effort, which is why the use of battery-powered compressors is necessary.
  • the fine pressure gauge regulates the spray pressure.
  • the compressor may comprise a pressure vessel, which is filled by the motor of the compressor with compressed air.
  • the pressure vessel is pressurized by the compressor.
  • By pressing the trigger of the spray gun compressed air flows out of the pressure vessel and atomizes the paint contained in the paint bottle. If the pressure in the autoclave falls below a certain, predetermined minimum value, the compressor starts to work again and increases the pressure to the previously set value. Thus, the compressor does not have to run during the entire painting process, which results in an energy saving that allows a longer painting time.
  • the pressure in the pressure vessel of the compressor can be 2 bar to 8 bar.
  • the motor of the compressor pressurizes the pressure vessel with a pressure of 2 to 8 bar. This is a pressure sufficient to generate a suitable spray pressure.
  • the filter may have a cylindrical shape with a truncated cone mounted on the cylindrical shape, the truncated cone being disposed at the end of the cylindrical body which faces inside the paint bottle, the truncated cone having a hole at the narrow end, whose diameter is smaller than the diameter of the at least one ball which is present in the paint vial, and on the lateral surface has at least one hole whose diameter is smaller than the diameter of the at least one ball, and wherein the cylindrical shape and the truncated cone are made in one piece ,
  • the at least one ball in the paint bottle is used to mix the color. Since the paint bottle is inserted into the paint gun with the opening down into the receptacle, the ball can clog the opening.
  • the filter makes this impossible.
  • the ball lays on the hole at the narrow end of the truncated cone, the paint can flow through the holes in the lateral surface in the paint spray gun.
  • the size of the holes in the filter is dimensioned so that the ball can not pass through.
  • the truncated cone is preferably designed so that the horizontal distance between the narrow end of the truncated cone and the inner surface of the paint bottle is smaller than the diameter of the balls, so that the balls can not lay on the holes of the lateral surface.
  • the compressor may be disposed in an insulated housing. This fulfills the worker protection.
  • Another aspect of the invention relates to the use of a portable painting system according to any one of the preceding claims for repairing paint damage in aircraft.
  • the use in aircraft is preferred, since there are strict rules in terms of pressure vessel and power requirements in aircraft.
  • the on-board network in large passenger aircraft has a rated voltage of 115/200 V and 400 Hz. Therefore, commercial air compressors can not be used.
  • the entrainment of pressure vessels is also possible only after enormous bureaucratic effort, which is why the use of battery-powered compressors is necessary.
  • the paint damage may be at most the dimensions of an A4 sheet (210 x 297 mm).
  • A4 sheet 210 x 297 mm.
  • Fig. 1 shows a painting system according to the present invention.
  • Fig. 2 shows a filter according to the present invention.
  • the painting system 1 comprises a compressor 2, a fine gauge 3, a hose 4, an exchangeable paint bottle 5 and a spray gun 6.
  • An accumulator 7 is connected to the compressor 2, the provides the energy for the compressor 2.
  • a carrying handle 13 is provided to carry the painting system 1 to the desired location.
  • the spray gun 6 has a receptacle 8 for the exchangeable paint bottle 5, wherein the receptacle 8 is formed for the paint bottle 5 suitable for the paint bottle 5.
  • the paint bottle 5 can thus fit to be inserted into the receptacle 8, it can not leak any color, since the connection between the paint bottle 5 and 8 recording is made sealing.
  • the fine gauge 3 is arranged between the compressor 2 and the hose 4. By the fine gauge 3, the pressure at the spray gun 6 is adjusted. With the trigger 12 of the painting process is performed. The display of the pressure on the fine gauge 3 corresponds approximately to the pressure at the end of the spray gun 6 and thus the spray pressure. The pressure on the compressor 2 can be read by the pressure gauge 11.
  • the paint spray gun 6 is arranged at the end of the hose 4, which faces away from the compressor 2.
  • the paint bottle 5 contains at least one ball 9. This at least one ball 9 is used to mix the color in the Lachfläschchen 5.
  • a filter 10 is disposed between the receptacle 8 for the paint bottle 5 and the paint bottle 5.
  • This filter 10 prevents slipping of the at least one ball 9 in the receptacle 8 and subsequently in the paint spray gun 6.
  • the compressor 2 may include a pressure vessel, which is filled by the motor of the compressor 2 with compressed air.
  • the pressure vessel is pressurized by the compressor 2 with a pressure.
  • a minimum value for the pressure in the pressure vessel is set. If this is exceeded, the compressor 2 switches on again and pressurizes the pressure vessel with a pressure which corresponds to the predetermined target value.
  • the pressure in the pressure vessel of the compressor 2 may for example be 2 bar to 8 bar.
  • the motor of the compressor 2 pressurizes the pressure vessel with a pressure of 2 to 8 bar.
  • the filter 10 may have a cylindrical shape 10e with a truncated cone 10c mounted on the cylindrical shape 10e, the truncated cone 10c being disposed at the end of the cylindrical body 10e facing inside the paint bottle 5, the truncated cone 10c at the narrow end Hole 10a, whose diameter is smaller than the diameter of the at least one ball 9, in the Paint Vial 5 is present, and on the lateral surface 10d at least one hole 10b, whose diameter is smaller than the diameter of the at least one ball 9, and wherein the cylindrical shape 10e and the truncated cone 10c are made in one piece.
  • the cylindrical mold 10e is made to fit with the inner surface of the paint bottle 5, that is, no liquid such as paint can pass between the outside of the cylindrical mold 10e and the inner surface of the paint bottle 5.
  • the at least one ball 9 in the paint vial 5 serves to mix the color. Since the paint bottle 5 is inserted into the spray gun 6 with the opening - in use - down in the receptacle 8, the ball 9 can clog the opening. By using the filter 10 this is impossible.
  • the at least one ball 9 lays on the hole 10a at the narrow end of the truncated cone, the paint can flow through the holes 10b in the lateral surface in the paint spray gun 6.
  • the size of the holes 10a, 10b in the filter is dimensioned so that the ball 9 can not pass.
  • the truncated cone 10c is preferably designed so that the horizontal distance between the narrow end of the truncated cone 10c and the inner surface of the paint bottle 5 is less than the diameter of the balls 9, so that the balls 9 not can put on the holes 10b of the lateral surface.
  • it is safe to use any varnish bottle 5 that is commercially available. A blockage of the spray gun 6 is impossible.
  • the compressor 2 may be arranged in a insulated housing. This complies with the health and safety regulations.
  • the work with the painting system 1 can be carried out simultaneously with other work in the aircraft.
  • the painting system 1 as described above can be used to repair paint damage in aircraft.
  • the damage to the paint can not exceed the dimensions of an A4 sheet (210 x 297 mm).
  • A4 sheet 210 x 297 mm.
  • spot repair ie the small area painting small damage to the surface of a component.
  • the painting system 1 is ideal for painting in the aircraft, since it does not need an external power supply, has no pressure bottle and also does not need a transformer.
  • a transformer for conversion to the usual voltage of 230 V at 50 Hz is not necessary; such a takeover would again require very high documentation effort.
