Definitions

  • the invention relates to a method for coating a workpiece and an atomizer for the series coating of workpieces with outlet openings for a gas flow confining the spray cone according to the preamble of the independent claims.
  • it is the control of the shaping air of electrostatic rotary atomizers, as used for the serial coating of workpieces such as e.g. Vehicle bodies are common.
  • the invention is suitable for any coating material including wet paint and powder paint.
  • annular gap-shaped Auslassö Stammsan can be provided for the shaping air.
  • an outer annular gap is provided in addition to a radially inner annular gap for the actual steering air, which is fed by the same source of compressed air as the inner annular gap.
  • the gap width of one or both annular gaps is adjustable.
  • the supplied by the additional annular gap outer air jacket has the task to compensate for the resulting from the color cloud in cooperation with the inner air jacket edge turbulence and due to the color particles breaking out into the cloud.
  • Rotary atomisers are also known in which, in addition to radially inner air openings, radially outer auxiliary air outlet openings are provided to prevent backward movement of the paint particles into the atomizer.
  • nebulizers which differ in diameter, spray direction and Lenkluftmenge and should be selected depending on the shape of the object to be coated and the color used, etc., for example, large diameter for outer surfaces and small diameter for interior surfaces of vehicle bodies.
  • the invention has for its object to avoid the disadvantages and to provide a method or a nebulizer, which allows the adjustment of the spray jet width without mechanical control of Auslassö Stammsan instrument in a much wider range than previously and yet optimal coating operation with good order efficiency and good Lackiertown guarantee.
  • the at least two shaping air flows (or other gas flows having the same purpose) which are regulated in the closed loop are normally not generated simultaneously, but are optionally used as a function of the workpieces or workpiece areas to be coated. It is also the simultaneous one Combined use of both separately from the other separately regulated air currents possible.
  • the invention enables the painting of complex workpiece geometries and especially of complete bodies including interior, exterior and detail painting with the same rotary atomizer with maximum achievable paint application efficiency by specifically set spray jet widths throughout the required range.
  • the spray jet widths can each be optimally adapted to the object to be coated.
  • the in Fig. 1 illustrated electrostatic high-speed rotary atomizer correspond to the prior art, for example, according to the already mentioned DE 4306800 .
  • the on In the known manner sits on the bell cup 1 facing the front end of the atomizer 2 coaxially with the Zerstäuberachse 3 a shaping air ring 4.
  • the radially extending end face 5 of the shaping air ring 4 which faces the bell cup 1 and thus the spray cone formed by the sprayed coating material, open the bores 12, 13 described below for the leaving air for adjusting the spray jet width. Due to the uninterrupted continuous outer shape of the entire Zerstäuber architectures Heilverwirbelonne be avoided around the atomizer and undesirable influence of Absprühvorgangs on the bell cup 1 and contamination of the atomizer housing ,
  • the end face 5 of the shaping air ring 4 can be located axially behind the bell cup 1 as in the illustrated embodiment, wherein it can extend as shown radially inwardly to close to the hollow shaft of the bell cup driving air turbine.
  • the shaping air ring could also be inserted completely into the open front end of the atomizer housing. In other embodiments, however, the shaping air ring may also extend with its outlet opening arrangement axially further forward beyond the bell cup.
  • Fig. 2a and Fig. 2b show the directing ring 4 for themselves.
  • In its end face 5 open onto two to the Zerstäuberachse 3 ( Fig. 1 ) and thus to the coinciding with them Sprühkegelachse concentric pitch circles 10 and 11 with different diameters each of wreaths distributed with uniform angular intervals Lenkluftbohrept 12 and 13 respectively.
  • the bores 12 and 13 each open parallel to the axis in the end face, but are also other arrangements possible.
  • the radially inner bores 13 are fed by an annular channel 14 within the shaping air ring 4, which is connected to a (not shown) compressed air line of the atomizer, while the outer bores 12 of the shaping air ring 4 from the end face 5 from first axially and then as shown with a rear part 16 extend approximately parallel to the peripheral surface 7 radially outwardly to an annular channel 17 which is formed with built-in shaping ring between the back and the adjacent parts of the atomizer and is fed by another compressed air line of the atomizer.
  • the two compressed air lines mentioned can be connected, for example, each with a compressed air connection of the atomizer for external lines, which can each lead to its own air control system.
  • the compressed air lines can also be connected via a switching valve controlled as a function of the workpiece area to be coated in each case to a bore 12 and 13 common air control system.
  • the switching valve need not be located outside of the atomizer, but may also be installed in the atomizer, for example in the valve unit 18, so that then only a single external steering air connection is required.
  • the shaping air could also be regulated within the atomizer.
  • the first controlled shaping air is preferably obtained from the radially inner bores 13 for setting wider spray jets (for example for SB 50% from 250 to 300 mm) for exterior painting used, while with the separated separately from the first shaping air second shaping air from the holes 12 on the larger pitch circle 10 narrower spray jets (for example SB 50% from 50 to 300 mm) are set for detail and interior painting, it may be appropriate when the two areas overlap (as in the example considered).
  • the spray jet width can be adjusted in the entire area required for exterior, interior and detail painting (in the example under consideration 50 to 550 mm) without interrupting the coating operation and without accepting significant disadvantages.
  • the two steering joints can be used and controlled separately, ie while the atomizer works with one lenk Kunststoff, the other steering air can be switched off.
  • the emerging behind the bell cup 1 first steering air from the inner bores 13 is relatively far back on the conically tapering rear peripheral surface of the bell cup 1, wherein the bell cup an air cushion generated and thereby advantageously a uniform air distribution is effected during atomization.
  • the second shaping air from the outer bores 12 can be directed so that it impinges on the paint material to be sputtered or already partially atomized by the rotation at a small radial distance (for example of the order of 1 mm) outside the spray edge of the bell cup a stronger constriction of the spray is caused than by the shaping air from the inner bores so that maximum application efficiency is achieved and difficult to reach or small workpiece areas can be coated well.
  • Fig. 3 the front part of a mounted for example on the wrist of a robot electrostatic rotary atomizer for powder coating or other powder coating material shown in longitudinal section.
  • the atomizer contains a powered by compressed air drive turbine 30 for example, in the front end of the hollow shaft 31 fixed rotating atomizer 33.
  • the hollow shaft 31 extends coaxially serving as a powder channel of the atomizer cylindrical tube 32 into the hub portion 35 of the bell 33 into where he presents as shown axially outside of the atomizer 36 opens.
  • the powder tube 32 is connected in the atomizer to a powder hose (not shown) coming from an external air and powder supply.
  • the atomizer 33 is in a known manner ( EP 1238710 ; US 5353995 ) substantially of an outer part 38 attached to the hub part 35, which has an inner conical surface 40 of the form shown, and an inner part 42 seated in the space in front of the surface 40, which faces one of the surface 40 to form a gap channel 44 Inner surface 46 and is rigidly connected to the outer part 38.
  • the gap channel 44 is thus bounded by the two conical surfaces 40 and 46.
  • the radially outer peripheral surface 49 of the outer and axially rear, ie the main part of the atomizer facing bell member 38 is shown extending (and in contrast to the mentioned known powder bells) only slightly conically widening forward so that they with the axis of rotation at an acute angle of preferably less than 20 °, in the illustrated example about 5 °.
  • the coating powder can be charged to high voltage in the usual way.
  • a controllable shaping air flow 50 (or other gas flow) which surrounds or surrounds the spray cone in an annular manner acts, which can be directed approximately parallel to the axis.
  • the directions indicated by the illustrated arrows may be such that they do not intersect the outer surface of the bell 33, but pass close to the bell.
  • the radially outer gas flow 51 may be directed approximately to the powder exit point of the atomizer 33.
  • the radially outer flow 51 is not circular in shape here as the flow 50, but consists of separate, for example, flat upper and lower parts that flatten (ovalize) when hitting the inner flow 50 and the spray cone in an oval cross-sectional shape.
  • the provided for this purpose outlet openings are in the schematic representation of Fig. 4 recognizable. While the annular shaping air flow 50 emerges from the ring concentrically surrounding the axis of rotation of a plurality of openings 52, two straight slots 53 and 53 'can be provided for the two planar parts of the flow 51, which are tangent to one another to the circular ring formed by the openings 52 on opposite sides of the axis of rotation are parallel.
  • the slots 53, 53 ' are so symmetrical to the axis of rotation that the perpendicular to the longitudinal direction of its mouth opening connecting its center line intersects the axis of rotation.
  • the slots 53, 53 ' are fed by compressed air lines 54 on their atomizer side. Instead of the two slots and parallel rows of each sufficiently large openings could be effective.
  • the shaping air openings 52 and / or the ovalization slots 53, 53 ' may be located in an annular body 55 which is removably and quickly and easily fastened to another atomizing air ring with another outlet opening arrangement interchangeable with the atomizer.
  • the atomizing bell 33 With the shaping air ring, the atomizing bell 33 can also be adapted to the workpiece area to be coated be replaced with another bell. The remaining part of the rotary atomizer can remain unchanged.
  • the bells and Lenkluftringe can be changed automatically, for example by controlling the robot.
  • a significant advantage of the rotary atomizer described here is that the same base atomizer can be used for example in the program-controlled body painting both for the outer surfaces and for the automatic interior painting.
  • a round bar with a smaller diameter is expediently produced than in the exterior finish, which is ovalized by the air flow flowing planar from the slots 53, 53 'at the powder exit point of the atomizer bell 33.
  • the rotary atomizer coat all or at least different workpiece surfaces with the same bell and the same outlet opening arrangement, wherein only the gas flows 50, 51 are changed by means of the control circuits for adaptation to the respective workpiece areas.
