Definitions

  • the invention relates to a spray device for applying a liquid medium such as paint, with a spray gun which is connected to a medium source and which has an outlet nozzle for the medium under pressure.
  • Spraying devices of this type which operate in the low pressure process at approximately 0.1 to 6 bar.
  • the medium emerges through a round nozzle of the spray gun with a constant cross-section and is atomized by compressed air which is emitted at the same time.
  • the compressed air can encircle the emerging medium jet and distribute it atomizing over a larger diameter, whereby horn air striking this medium jet can compress the jet with further atomization.
  • a large-area application jet is generated with the so-called airless atomization system, while a narrow application jet can be produced with the low-pressure system.
  • EP-0 408 786 A1 discloses a spray gun that is always operated with compressed air in order to atomize paint.
  • a comparable spraying device is known from DE 38 22 835 A1, here too the paint emerging from the spray gun is always atomized by compressed air, the size of the air pressure and the amount of paint supplied being able to vary in order to be independent of the type of paint or of the paint, from the feed geometry of the spray gun or the workpiece and its geometry to consistently constant painting results without the formation of drops or blobs.
  • a spray device for applying a liquid medium such as paint etc. with a spray gun which is connected to a medium source and has an outlet opening for the pressurized medium
  • the spray device optionally in the medium -High pressure range without compressed air and in the medium-medium pressure range or low pressure range can work with compressed air.
  • a motor drives either an air compressor, a piston diaphragm pump and / or a worm pump via couplings, the suction side of the piston diaphragm pump being able to be acted upon by the outlet of the worm pump and the air compressor also being operatively operable with the screw press.
  • the present invention is based on the object of specifying a spraying device which can be used both for large-area paint application and for paint application along a very narrow strip.
  • a method for applying a liquid medium such as paint etc. with such a spray device is to be specified.
  • the spraying device according to the invention can optionally work in the medium high pressure range without compressed air or in the medium medium pressure range or low pressure range with compressed air.
  • the spray device for applying a medium, such as paint, etc. can thus be used universally on surfaces of different sizes and widths, and enables a considerably faster and more economical application process than the spray devices known hitherto.
  • the outlet opening of the medium outlet nozzle is surrounded by an annular nozzle and / or a plurality of opposing nozzles which are directed obliquely inwards onto the emerging medium jet and which are connected to the compressed air source, it being preferred that the outlet opening has a cross-section has a conical shape.
  • an air control valve which switches the air supply ON or OFF, an air control valve for the ring nozzle and / or an air control valve for horn air nozzles are arranged in the lines connecting the compressed air source to the spray gun.
  • an external control unit for the media pressure and the air valves is arranged, with the keyboard of which the parameters of the spray gun or spraying device can be set.
  • the control unit advantageously has a monitor which displays the set / actual parameters.
  • the horn air compressing the medium jet more or less flat can emerge from one or more opposing pairs of horn air nozzles, and it is within the scope of the invention to arrange two or more concentric ring nozzles instead of an annular nozzle, which can optionally deliver compressed air.
  • the spraying device can work with compressed air as well as without compressed air, preferably a hydraulic volume metering device supplying the medium preferably working in a pressure range of approximately 10 to 300 bar.
  • the medium pressure is preferably 70 to 300 bar, while the medium pressure in the medium-pressure process is preferably approximately 10 to 80 bar.
  • the liquid medium is atomized and distributed according to the nozzle geometry without compressed air escaping from the air nozzles.
  • the application jet is to be constricted in order to reduce the jet width, for example because the intended application area has only a reduced width or because e.g. if a paint application of greater concentration is to take place
  • the control device for the medium reduces its pressure from high pressure to medium pressure. If compressed air is now emitted from the ring nozzle and / or the horn air nozzles arranged at an angle to the jet axis, this can change the medium jet geometry as a function of the pressure of the ring air and / or the horn air, so that the jet constricts to a desired width can be.
  • the ON / OFF air control valve between the compressed air source and the spray gun is closed, and the volume dispenser feeds the medium at a pressure of approx. 70 to 300 bar, which, as mentioned, results in the medium alone of the material pressure is atomized and a large-area application jet is created.
  • the application jet is to be restricted in order to apply the paint to a small area
  • the ON / OFF air control valve is opened, the pressure of the medium is reduced to approx. 10 to 70 bar and the compressed air supply to the ring nozzle and the horn air nozzles is adjusted in such a way that that the medium jet is constricted to the desired extent.
  • the emerging medium jet can be compressed quite flatly, so that paint can be applied along a very narrow strip, if this is desired.
  • high-pressure operation - without constriction due to ring air and horn air - a very wide, large-area medium jet can be emitted, which is suitable for large-area application.
  • the spray device according to the invention is therefore ideally suited for applying a medium such as paint to surfaces of different widths and thereby replaces the two spray guns previously required, which were each operated at different pressures. In this way, such an application process is considerably quicker and more cost-effective.
  • a hydraulic volume meter is preferably used as the control device for the medium to be applied, which adjusts the volume of the emerging medium and its pressure to the desired level.
  • a control device for the air pressure is provided according to the invention, which should also offer the possibility of optionally allowing the air outlet from the ring nozzle and / or the horn air nozzles in order to influence or change the medium jet geometry in the desired manner.
  • the pressure of the exiting air is adjustable, and any air outlet can also be switched off, which is provided in particular in high-pressure operation.
  • the medium outlet nozzle can have a slot-shaped opening which opens conically in a cross section, or else a circular, conically widening outlet opening.
  • the spray device contains a spray gun 1, which is connected to a compressed air source 5 via lines 2 to 4.
  • a compressed air source 5 via lines 2 to 4.
  • an ON / OFF air valve 6 an air control valve 7, which adjusts the compressed air supply to the horn air nozzles, not shown, and an air control valve 8, which is provided for the compressed air supply to the ring nozzle, also not shown.
  • the spray gun 1 is also connected via a line 9 to a hydraulic volume metering device 10, the oil inlet of which is designated 11 and the material inlet 12.
  • a control unit 13 for the volume dispenser 10 and the air valves 6 to 8 contains a monitor which displays the set / actual parameters, and an operating keyboard 15 with which the parameters of the medium and compressed air delivery can be set or changed.
  • the hydraulic volume metering device 10 guides the medium at high pressure, i.e. with about 70 to 300 bar, and the air control valve 6 switches to OFF and thus interrupts the compressed air supply to the spray gun 1. If, on the other hand, the medium jet is to be narrowed, the volume metering device 10 reduces the pressure of the medium to approximately 10 to 70 bar, which Air control valve 6 is turned ON and the air control valves 7 and 8 adjust the compressed air supply to the ring air nozzle and the horn air nozzles according to the parameters entered in the control unit 13, whereby the desired medium jet geometry is generated.
