Definitions
- the invention relates to a method for serial coating of workpieces such as motor vehicle bodies with paint material containing effect particles and one for this electrostatic rotary atomizer to be used.
- a deflection part also known as a distributor disc, that divides the material flow into partial flows, one of which directly onto the overflow surface of the Bell plate arrives while the other partial flow passes through central Openings of the deflecting part on the front and first from there flows onto the overflow surface of the bell cup.
- the Material flow to the trailing edge is due to relatively strong deflections more or less turbulent in the area in front of the spray edge, what u.a. considerable differences in paint droplet size of the sprayed and atomized coating material for Consequence. The differences can be more than 100 ⁇ m.
- Electrostatic rotary atomizers are characterized by high Application efficiency (ratio of the amount sprayed to the applied amount) of about 80% and have to be applied normal paint materials have been tried and tested for a long time.
- Paint material e.g. metallic paint
- Paint material with exclusive Not possible to use the known rotary atomizers.
- the reason for this is that the relatively large effect particles tend to look in the very different sized paint droplets aggregate and focus on hitting the to erect or "float" the coating surface.
- the result is a significant deterioration in the target Surface effects that form the nests of the effect pigments as well as different brightness depending on the viewing angle (“Flip-flop"), and color changes at different slants Viewing angles becomes visible.
- the object of the invention is a method or to specify a rotary atomizer that has a qualitative flawless, especially cloud-free application of effect paints with a significantly higher application efficiency enable than before.
- the invention provides a qualitatively optimal effect painting enabled with the greatest possible application efficiency. This does not only involve extensive separation of the effect pigments and their very even distribution in the paint film achieved, but above all a flat orientation of the Effect particles on the coated surface.
- the applied A droplet (measured after spraying and before impact) Do not exceed a droplet diameter of 60 ⁇ m and should preferably be between 10 to 60 ⁇ m and one to should contain two effect pigments to form a cluster to avoid the effect pigments.
- the applied droplets should be as high as possible when hitting the object Solids have reached an erection or floating to avoid the effect pigments.
- the droplet size was not only of depends on the dynamic viscosity of the paint, but affected becomes constant by the size of the along the overflow surface permanent color flow angle of the bell cup and diameter and geometry of the spray edge and also by the amount of paint discharge and the bell plate speed. Changes and agglomerations the effect pigments are protected by paint Paint flow prevented.
- the desired high solid content applied droplet is mainly due to solvent loss when flowing over the bell plate and on the way to Workpiece reached.
- the flow angle between the axis of rotation and the overflow surface at least in Area between the usual distributor disc and the spray edge remain constant and preferably be between 50 and 85 °.
- the distributor plate diameter should preferably be less than 40% of the bell or spray edge diameter, which in comparison with the usual bell plates the exposed surface area of the overflow area Reduction of the distributor disc is increased, so as possible a lot of solvent from across the overflow area flowing paint can evaporate.
- the diameter of the spray edge is preferably larger than usual, in particular 63 to 75 mm, which increases the surface area and at the same time the thickness of the paint film reaching the spray edge is reduced.
- the rotary atomizer 20 shown in Fig. 1 can up to his bell plate 22 designed according to the invention itself be of a known type (see e.g. DE 43 06 800 C2) and must therefore so far are not described in detail.
- the conical outer surface of the Bell plate 22 acting axial air nozzles 23 is too mention that to form the sprayed coating material serve.
- the bell plate has a rotationally symmetrical shape 22 a central opening 24 coaxial with the axis of rotation, through which to be sprayed supplied by a paint tube 25 (Fig. 1) Paint material on the end face facing the workpiece the main body of the bell plate 22 arrives.
- This End face consists of an adjoining the central opening 24 relatively small area 28 that is transverse to the axis of rotation runs, and a subsequent conical overflow surface 30, which is continuous from area 28 as shown smooth and with constant angles with respect the axis of rotation extends to the spray edge 32.
- the constant angle of the overflow surface is in the example shown in the order of 60 °, corresponding to the illustrated angle ⁇ of approximately 30 ° with respect the spray edge.
- a distributor disk serving deflection part 40 is arranged, which is a general parallel to the surface area 28 of the bell plate 22 Rear surface 42 and then preferably one conical rear surface running parallel to the overflow surface 30 44 has.
- the deflection part is provided with central openings (Fig. 4) and serves in a known manner to divide the coating material emerging from the central opening 24 in Partial streams, one of which is directly between the surface area 28 and the rear surface 42 on the overflow surface 30 flows while the other partial stream flows over the front of the Deflection part 40 reaches the overflow surface 30 and there mixed with the first partial flow.
- the top view of Fig. 3 shows the proportions of the overflow surface 30 and the deflecting part 40.
- the diameter of the Deflection part can, for example, about 1/3 of the diameter Spray edge 32 amount. In the example shown, can the spray edge has a diameter of approximately 65 mm, the deflecting part 40 has a diameter of approximately 22 mm.
- the bell plate has on its back facing away from the workpiece 22 a mounting hub 31 for mounting in the rotary atomizer and a ring surrounding the mounting hub Collar part 33 with an external thread 34.
- On the external thread 34 is screwed a frustoconical side wall 35, the behind the spray edge 32 on the back of the bell body e.g. can be welded or glued.
- the main body of the bell plate is hollow in the space 38 behind the overflow surface 30, whereby the mass the bell plate is reduced.
- the overflow surface forms with the outer surface of the bell plate, i.e. the side wall 35 an acute angle of less than 45 ° in the illustrated Example about 30 °. It is also essential that the between the overflow surface 30 and one to the conical outer surface the side wall 35 leading small chamfer formed spray edge 32 should be as sharp as possible.
- its bell plate 20 expediently consist of a titanium alloy, preferably one TiAl alloy.
- other light metals can also be used A1-based, especially if other materials are used such as.
- Clear varnish should be applied.
- Spraying of clear lacquer can overflow surface 30 in the area before the spray edge 32 contain the usual longitudinal grooves.
- the deflection part 40 is shown enlarged in FIG. 4. His Leading like a labyrinth from the rear surface to the end surface 52 central opening system 50 contains e.g. four axial channels 54 and one across their mouths as shown transversely to Axial inner deflection element. On the main body of the Bell plate is the deflecting part 40 with preferably three even angular spacing around the axis holding pins 56 releasably attached with a press fit. The gap-like space between the deflection part 40 and the one facing it End face of the bell plate 22 (Fig. 2) is only through the middle disk-shaped spacer 58 of the holding pins 56 interrupted.
- the described bell plate ensures 22 for smaller size deviations of the sprayed paint droplets than with conventional rotary atomizers, which means a Position control of the effect particles is facilitated.
- Size of the atomized sprayed from the spray edge 32 Paint droplets are known to affect the speed of the shaping air as well as the speed of the bell plate and the color flow can be set so that the effect particles are forced to lie flat on the surface to be coated. Due to the small size differences of the paint droplets can use these parameters for a high percentage of paint material can be optimized for the desired color effect.
- the smaller droplet size deviation is a result of various essentials Aspects of the bell cup 22 and the deflecting part 40.
- Proportion of solvent (which in the case of water-based paint is known to be largely water) evaporates, before the paint material reaches the spray edge 32.
- the relatively large diameter of the spray edge 32 forms this is an advantageously thin paint film.
- the low ratio of the diameter of the deflection part 40 to that of the spray edge 32 ensures a more constant, laminar flow of material over the overflow surface 30 to the spray edge 32.
- the conical overflow surface 30 from the deflection part 40 to the spray edge 32 continuously and is smooth and has a constant angle ⁇ with the spray edge forms is also the paint flow rate up to the spray edge constant, i.e. there are no oscillations. As a result this results in better control of the paint droplet size. Since also the bell plate 22 described in FIG. 2 only a few flow direction deviations between the central opening 24 and the spray edge 32 causes, and only relatively close to the central opening 24, result more constant, in essential laminar paint flow at the spray edge 32 and therefore also smaller droplet size deviations.
- FIG. 5 is a bell plate 100 according to another embodiment presented the invention, which is also something different Deflection part 110 and has even fewer directional deviations effected between the central opening 112 and the spray edge 132 than in the embodiment according to FIG. 2.
- the overflow surface 126 forming a straight, conical part of the end face the bell body extends here directly from the Middle opening 112 to the spray edge 132.
- the overflow surface 126 therefore does not contain a part running perpendicular to the axis (like area 28 in FIG. 2). This will make the laminar Paint flow further improved and droplet size deviations further decreased.
- the deflecting part 110 essentially has one here rectilinearly conical rear surface 144 adjacent to one central rounded back surface part, causing changes in direction the paint flow can be reduced to a minimum. Also here the rear surface 144 of the deflection part runs parallel to Face of the bell body, and the annular gap is only detachable with axially parallel holding pins Attachment of the deflection part 110 interrupted, one of which is shown schematically at 56 '. In contrast to the labyrinthine 4 are the opening system 50 of the back leading to the end face of the deflecting part 110 Openings from simple inclined with respect to the axis of rotation Bores 154.
- FIG. 6 shows a possible arrangement of the rotary atomizers used 20 (Fig. 1) in the coating zone 150 of a spray booth for coating motor vehicle bodies with basecoat shown.
- the body 152 moves in the direction of the shown arrow.
- the coating zone 150 contains, as shown 13 rotary atomizers for double color application.
- the basecoat applied with nine rotary atomizers and six air atomizers, so that the length of the coating zone 150 in contrast can be reduced by about 1/3.
- Rotary atomizer for the first color application vertically moved up and down.
- the next page machines 160 each have two rotating atomizers offset vertically and horizontally, on arms 161a for triaxial contour movements or on fixed arms 161b for the coating further body parts are arranged.
- Another pair of Side machine 162 is particular for a second side coating the vehicle doors.
- atomizers in a double coating system can also use conventional rotary atomizers whose application efficiency may a little higher can be that of the atomizer according to that described here Invention. In any case, however, is the overall efficiency much higher (e.g. about 75%) than that of known systems for the application of paint material containing effect particles with even better quality.
