Definitions

  • the present invention relates to a cleaning device for atomizers, in particular paint spray guns, according to the preamble of claim 1 and a method for cleaning an atomizer.
  • Atomizers are used to apply fluids, such as paints or coatings, to an object, such as a vehicle body.
  • a fine mist of the fluid is generated from a fluid, which can be applied to the object.
  • the atomizer is a hand-operated device for applying paints, this is often referred to as a paint spray gun because of the shape reminiscent of a firearm.
  • the atomizers on robots are used as air (cap) atomizers or bells, as well as with external electrodes with subsequent dry blowing.
  • the atomizers described above must be cleaned regularly, i.e. Remains of any fluid that may already have dried on. In particular, paint residues that have already dried on must be removed from the atomizer. Devices for this have become known from the prior art.
  • the GB 2 198 033 A. discloses a cleaning device for atomizers of the type mentioned.
  • a device for cleaning spray guns comprising a closed container with an inlet, an outlet and an opening for receiving a nozzle of a spray gun, a spray device which is rotatably mounted in said container and is in fluid communication with said inlet has become known said spray device having an offset cleaning nozzle for spraying a cleaning spray toward said opening and a rotating device for causing rotation of said spray device, said opening having a. Sealing device for sealingly receiving said spray guns and for positioning said nozzle of said spray guns in said cleaning spray, the rotary device having a rotary nozzle for spraying a rotary spray.
  • Cleaning devices are also known which do not have a rotating device.
  • the DE 101 10 098 A1 a cleaning device for paint discharge devices, with at least one cleaning container into which parts of the color discharge device to be cleaned can be plugged, at least one feed line being provided in the cleaning container and having at least one outlet for the cleaning agent directed against the parts to be cleaned.
  • the cleaning device described here also has a plurality of nozzles, the cleaning agent being supplied to the nozzles under pressure.
  • the cleaning device is characterized by a simple structure, in particular no rotating nozzles are provided, however, a considerable number of nozzles must be provided in order to free the paint discharge device from color residues on all sides. It is understandable that this results in a considerable consumption of cleaning agents, which is undesirable from both a cost and ecological point of view.
  • a cleaning device for paint spray guns is known, in which the cleaning medium is guided with the aid of hoses into the cleaning container in which the paint spray gun is located.
  • the DE 26 55 875 A1 discloses a multi-nozzle block for dusting tool surfaces, in which the products to be atomized are let into two lines from two supply lines and through two control valves assigned to them. There they are atomized by compressed air and then fed to nozzles made from a pressed or welded copper tube.
  • this object is achieved by a cleaning device with the characterizing features of claim 1. Because the mixing device is set up to supply the compressed air with a pressure difference with respect to the cleaning agent to the mixture outlet, and the mixing device is also set up to supply the compressed air with a higher pressure than the cleaning agent to the mixture outlet, a vaporization effect is achieved, i.e. the surface , and the volume of the cleaning agent is increased many times over, so that maximum cleaning success with the lowest consumption of cleaning agent can be achieved in the shortest cleaning time in relation to known cleaning methods and cleaning devices.
  • a proposed cleaning device enables compressed air and cleaning agent to be saved by up to 90%. The consumption of cleaning agent is only about 6 to 10 ml per cleaning process for a spray gun.
  • a first and a second rinsing tube are provided as the spraying device, the rinsing tubes protruding into the housing, the rinsing tubes having a geometric longitudinal axis and the rinsing tubes being aligned with the atomizer receptacle in such a way that the geometric Cross the longitudinal axes at the center of the atomizer holder.
  • pipes with a constant cross-section in the longitudinal direction are used, which are set up to spray the mixture of compressed air and cleaning agent onto the atomizer to be cleaned, there is a risk that such a flushing pipe will become clogged, for example due to dried paint residues, significantly lower.
  • the mixing device is set up to supply the compressed air to the mixture outlet with a pressure difference of 2 to 4, preferably 3 bar, relative to the cleaning agent. With a pressure difference of 3 bar, cleaning results are particularly good.
  • the mixing device is set up to supply the cleaning agent to the mixture outlet at a pressure of approximately 1 bar and the compressed air to the mixture outlet at a pressure of approximately 4 bar. Particularly good cleaning results were achieved at these pressures and the resulting pressure difference.
  • the mixing device is set up to supply the cleaning agent to the mixture outlet at a pressure of approximately 2 bar and the compressed air to the mixture outlet at a pressure of approximately 5 bar. Particularly good cleaning results were achieved at these pressures and the resulting pressure difference.
  • a nozzle is provided between the detergent inlet and the mixture outlet, the nozzle having a diameter of 0.5 to 2 mm. Such a nozzle between the detergent inlet and mixture outlet can essentially ensure that the preferred pressure difference of 3 bar can be produced.
  • the cleaning device has a housing and a cover, the cover being set up to receive the atomizer receptacle, the housing being set up with fastening means for fastening the cleaning device, the cover being connected via spring elements to the Housing is connected.
  • a cleaning device designed in this way opens up the possibility of compensating for position tolerances by the atomizer receptacle being able to be displaced with respect to the housing and thus with respect to a fastening position. This possible compensation of position tolerances is particularly important in the context of integrating the cleaning device into existing painting systems or when positioning the atomizers in the atomizer holder by robots.
  • the atomizer receptacle is equipped with a funnel facing the spraying device.
  • a funnel can advantageously be provided to appropriately direct the compressed air / cleaning agent mixture to the center of the atomizer holder, so that a maximum cleaning effect can be achieved.
  • the housing is designed as a vessel, an outlet being provided on the bottom side of the vessel.
  • the cleaning agent sprayed onto the atomizer to be cleaned and the contaminants of the atomizer can flow into the vessel and then flow out through the drain.
  • Another object of the present invention is to propose a method for cleaning an atomizer with a cleaning device according to one of the preceding claims, which is characterized by maximum cleaning success with the lowest consumption of cleaning agent.
  • this object is achieved in that the compressed air is fed to the mixture outlet with a pressure difference with respect to the cleaning agent, the compressed air being fed to the mixture outlet at a higher pressure than the cleaning agent.
  • This measure achieves a vaporization effect, i.e. the surface area and the volume of the cleaning agent are increased many times over, so that maximum cleaning success with the lowest consumption can be achieved in the shortest cleaning time in relation to known cleaning methods and cleaning devices.
  • a proposed cleaning device enables compressed air and cleaning agent to be saved by up to 90%. The consumption of cleaning agent is only about 6 to 10 ml per cleaning process for a spray gun.
  • the cleaning agent is fed to the mixture outlet at a pressure of approximately 1 bar and the compressed air to the mixture outlet at a pressure of approximately 4 bar. Particularly good cleaning results were achieved at these pressures and the resulting pressure difference.
  • the cleaning agent is fed to the mixture outlet at a pressure of approximately 2 bar and the compressed air to the mixture outlet at a pressure of approximately 5 bar. Particularly good cleaning results were achieved at these pressures and the resulting pressure difference.
  • a cleaning device essentially comprises an atomizer holder 3, a first flushing tube 1 and a second flushing tube 2.
  • the flushing tubes 1, 2 are aligned with the atomizer holder 3 in such a way that a compressed air / cleaning agent mixture emerging from the flushing tubes 1, 2 is one in the Atomizer receptacle 3 received atomizer 8 can reach.
  • a cleaning device according to the invention further comprises a mixing device 9 with a compressed air inlet 10, a cleaning agent inlet 11 and a mixture outlet 12.
  • the mixing device 9 is suitable for mixing the preferably liquid cleaning agent supplied via the cleaning agent inlet 11 with the air supplied via the compressed air inlet and for the resulting air Dispense compressed air / detergent mixture from the mixture outlet 12, the flushing pipes 1, 2 being connected to the mixture outlet 12 via suitable feed lines 16, so that the compressed air / detergent mixture can ultimately be dispensed via the flushing pipes 1, 2.
  • a housing 5 and a cover 4 are also provided, the cover 4 being designed to accommodate the atomizer holder 3 and the housing 5 being designed to accommodate the flushing tubes 1, 2.
  • the housing 3 is designed essentially in the shape of a hollow cylinder and is equipped on the head side with a circumferential collar 18.
  • the flushing tubes 1, 2 project into the hollow cylindrical housing 5 on opposite sides and have a suitable bend to align the flushing tubes 3, 4 in the direction of the atomizer receptacle 3, which is attached to the cover 4.
  • a geometrical longitudinal axis of the rinsing tubes 1, 2 is correspondingly aligned with the center of the atomizer receptacle 3. If, as proposed here, two rinsing tubes are assumed, the longitudinal axes of the spray tubes 1, 2 intersect at the center of the atomizer receptacle 3.
  • the housing 5 is also equipped with fastening means 15 for mounting the cleaning device, for example on a painting system.
  • the housing 5 can optionally be in the form of a hollow cylinder and open on the bottom, and can also be designed as a vessel 13 with a drain 14 on the bottom.

  • a funnel 6 is provided below the bore or below the atomizer receptacle 1, the opening of which basically faces the flushing tubes 1, 2. This ensures an even better deflection of the compressed air / detergent mixture emerging from the flushing pipes 1, 2.
  • the cover 4 is connected to the collar 18 via spring elements 7, which press the cover 4 onto the collar 18.
  • the cover 4 and thus the atomizer receptacle 3 can accordingly be moved slightly relative to the housing 5. This results in an advantageous possibility to compensate for position tolerances. This possible compensation of position tolerances is of particular importance in the context of integrating the cleaning device into existing painting systems or when positioning the atomizers 8 in the atomizer holder by robots.
  • the spring elements 7 are also set up for a quickly detachable connection between the housing 5 and the cover 4, so that, in addition to a movable mounting, quick and easy maintenance is made possible. So-called "quicklock" closures are preferably suitable for a detachable connection between cover 4 and housing 5.
