Definitions

  • the invention relates to a shaping air ring for a rotary atomizer according to the main claim.
  • rotary atomizers which emit a spray of a coating agent (for example wet paint) onto the components to be coated by means of a rotating bell cup.
  • a coating agent for example wet paint
  • the bell cup is partially housed, i. the shaping air ring surrounds the outer surface of the bell cup in the rear region of the bell cup, so that the shaping air ring has an axial overlap with the bell cup.
  • a disadvantage of this design is the fact that mandatory a so-called free-hold air is required to prevent contamination of the bell-shaped back.
  • JP 9 085 134 A a shaping ring according to the preamble of claim 1.
  • no annular recess is arranged in the end face of the shaping air ring.
  • the shaping air nozzles of the two shaping air nozzle rings do not alternate over the circumference.
  • a disadvantage of this known shaping air ring is therefore the fact that the various shaping air flows do not combine to form a single shaping air flow.
  • the invention is therefore based on the object to improve the known rotary atomizer described above accordingly.
  • the invention comprises the general technical teaching to provide a ring trough in the shaping air ring on the front side, into which a correspondingly adapted bell cup trailing edge of the bell cup protrudes in the axial direction during operation of the rotary atomizer.
  • the annular recess is therefore preferably circular and arranged coaxially with the axis of rotation of the bell cup, wherein the diameter of the annular recess the Diameter of the bell cup trailing edge of the associated bell cup corresponds, so that the bell cup trailing edge can protrude axially into the annular recess in the shaping air ring.
  • the above design rule here preferably refers to the center of the annular recess, since the annular recess has a certain radial extent.
  • the bell cup trailing edge can in this case be flush with the end face of the shaping air ring or sunk in the axial direction in the annular recess of the shaping air ring.
  • the axial overlap between the shaping air ring and the bell cup can be, for example, in the range of 1-3 mm or larger.
  • the annular recess therefore has a depth in the axial direction of at least 1 mm or at least 3 mm in order to allow the above-mentioned axial overlap between the shaping air ring and the bell cup.
  • the shaping air ring has a plurality of shaping air nozzle rings, each having a plurality of annularly distributed shaping air nozzles, wherein the individual shaping air nozzle rings each deliver a shaping air flow to the spray jet in order to form the spray jet.
  • the delivery of several shaping air streams from different shaping air nozzle rings advantageously enables a more flexible shaping of the spray jet, since the individual shaping air streams can be adjusted separately from one another.
  • the individual steering air nozzle rings are arranged coaxially with the bellcylinder shaft.
  • the two shaping air nozzle rings have essentially the same diameter.
  • About the scope of Lenklufttrings distributed is then alternately arranged a Lenkluftdüse one Lenkluftdüsenkranzes and a Lenkluftdüse the other Lenkluftdüsenkranzes.
  • nozzle groups are distributed over the circumference of the shaping air ring with at least one shaping air nozzle of the one shaping air nozzle ring and in each case at least one shaping air nozzle of the other shaping air nozzle ring.
  • the distance between the circumferentially adjacent nozzle groups is greater than the distance between the shaping air nozzles within the individual nozzle groups. This is advantageous because the Lenkluftströme exiting from the nozzles belonging to a group of nozzles then unite due to the small distance of these shaping air nozzles to a resulting Lenkluftstrom.
  • each of the individual nozzle groups is a nozzle pair, each containing exactly one shaping air nozzle of the one shaping air nozzle ring and in each case exactly one shaping air nozzle of the other shaping air nozzle ring.
  • the individual nozzle groups of the shaping air nozzle rings may also contain a different number of shaping air nozzles, such as three or more shaping nozzles per nozzle group.
  • the shaping air nozzles of the various shaping air nozzle rings are oriented differently and therefore deliver the respective shaping air flow in different directions.
  • the shaping air nozzles of the one shaping air nozzle ring each have an air outlet, which is aligned substantially parallel to the axis of rotation of the bell cup.
  • the shaping air nozzles of the other shaping air nozzle ring on the other hand can have an air outlet which has a swirl in the circumferential direction, so that the steering air flow from these shaping air nozzles has a predetermined swirl angle with respect to the axis of rotation of the bell cup.
  • the helix angle can be, for example, in a range of 50 ° to 60 °, wherein a helix angle in the range of 30 ° to 45 ° has proven to be particularly advantageous.
  • An advantage of such an orientation of the shaping air nozzles is the fact that the shaping air streams can combine and then form a resulting shaping air flow with a certain orientation. In this way, three different geometries of the resulting shaping air flow can then be achieved with two shaping air flows, in which the two shaping air flows are switched on or off.
  • the invention includes not only the above-described invention Lenkluftring, but also a complete rotary atomizer with the invention Lenkluftring.
  • the shaping air ring can in this case be designed as a separate component and fastened to the rotary atomizer.
  • the shaping air ring according to the invention is an integral part of the rotary atomizer or the rotary atomizer housing.
  • the shaping air ring can in this case be designed such that the shaping air flow passes with its central axis at a certain radial distance outside on the spray-off edge of the bell cup. This means that the shaping air jet is not directed to the outer surface of the bell cup, but to the spray jet delivered to the sprayer edge outside of the bell cup.
  • the radial distance between the spray-off edge of the bell cup and the central axis of the steering air flow can be in the range of 0-6 mm.
  • the steering air flow impinges with its central axis with a certain radial overlap on the outer surface of the bell cup.
  • the directing air flow is not directed to the spray jet discharged at the spray-off edge, but onto the outer surface of the bell-shaped plate.
  • the radial overlap between the central axis of the steering air flow and the outer surface of the bell cup may for example be in the range of 0-5 mm.
  • the configuration of the shaping air ring according to the invention advantageously allows relatively low speeds of the bell cup of less than 20,000 min -1, 15,000 min -1, or even less than 12,000 min -1.
  • the low speed of the bell cup allows in turn for a drive with a compressed air turbine, a reduction in the required air pressure to less than 8 bar.
  • the inventive design of the shaping air ring allows a limitation of the shaping air flow to a maximum of 600 Nl / min or even to less than 500 Nl / min.
  • the design of the shaping air ring according to the invention a lowering of the charging voltage to less than 70 kV, less than 50 kV or even less than 30 kV allowed.
  • Another advantage of the rotary atomizer according to the invention is the fact that the coating medium flow can be limited to less than 600 ml / min, 500 ml / min or even less than 400 ml / min.
  • the droplet size in the spray jet can have a particularly good statistical distribution.
  • the median value and / or the mean value of the droplet size are preferably in the range between 20-800 ⁇ m, whereby a range of 300-500 ⁇ m has proven to be particularly advantageous.
  • the standard deviation of the droplet size is preferably less than 500 microns, with a value of less than 400 microns or even less than 300 microns has been found to be advantageous. In the case of the rotary atomizer according to the invention, therefore, a large part of the sprayed-on coating agent droplets has a droplet size in the range of 20-800 ⁇ m.
  • the rotary atomizer according to the invention Optionally suitable for application of wet paint (eg solvent-based paint, water-based paint) or powder paint.
  • wet paint eg solvent-based paint, water-based paint
  • powder paint eg powder paint

  • a deflection plate 10 is mounted, the coating agent, which enters axially from the hollow bell cup shaft 4 in the bell cup 5, deflects radially outwardly onto the overflow surface 9, so that the coating agent finally at an annular peripheral spray-off 11 of the bell cup 5 is sprayed.
