Definitions

  • the invention relates to an atomizer, in particular a rotary atomizer, and an associated operating method.
  • the respective coating agent eg filler, basecoat, clearcoat
  • the respective coating agent is usually atomized by atomizers (eg high-rotation air or ultrasonic atomizer) and applied by Lenkluft and electrostatic charging of the coating composition on the component to be coated .
  • atomizers eg high-rotation air or ultrasonic atomizer
  • the wet paint loses in the atomization and during the application especially volatile components, such as solvents in solvent-based paints or water in water-based paints, which evaporate into the ambient air.
  • the percentage solids content of the applied wet paint changes compared to the percentage solids content of the wet paint before the atomization.
  • this increase in the solids content in the application is determined by the application parameters, such as rotational speed of the rotary atomizer, outflow quantity, directing air quantity and painting distance.
  • the increase in the solids content in the application of the ambient conditions is affected, such as humidity, Heiltsink für and air temperature in the spray booth, as these environmental conditions affect the evaporation of the solvent content or the water content.
  • the additional adapter disturbs the otherwise smooth outer contour of the rotary atomizer, whereby the tendency to fouling increases and the cleaning of the rotary atomizer is difficult.
  • the additional adapter obstructs the handling of the rotary atomizer, since the external dimensions and the inertia of the rotary atomizer increase by the additional adapter. For example, due to the larger external dimensions, the rotary atomizer with the additional adapter can no longer be inserted into small openings in order to coat surfaces located there.
  • a further disadvantage of the additional adapter is the relatively large axial distance between the sheath flow nozzles in the adapter and the bell-plate sputtering edge, so that energy and amount of the sheath flow are generally insufficient to achieve truly defined evaporation conditions.
  • the invention is therefore based on the object to improve the known painting.
  • sheath flow unlike the prior art discussed above, is not delivered by a separate adapter, but by sheath flow nozzles that are structurally integrated into the atomizer.
  • This structural integration of the sheath flow nozzles in the atomizer has the advantage that the smooth outer contour of the atomizer housing is not disturbed by the enveloping current technique, so that the tendency to fouling and cleaning ease of the atomizer are not affected.
  • the structural integration of the sheath flow nozzles into the atomizer makes it possible to supply the conditioned air for the sheath flow via the normal connection flange of the atomizer.
  • the separate hoses provided in the prior art for supplying the conditioned air can be dispensed with, eliminating the problem of hose breaks.
  • the invention advantageously allows for a reduction in the axial distance between the sheath flow nozzles and the bell cup spray edge so that the energy and amount of sheath flow are sufficient to produce truly defined flash conditions.
  • Another advantage of the invention integrating the Hüllstromdüsen in the atomizer is the better handling, since the outer dimensions and the inertia of the atomizer according to the invention over a conventional Atomizers without envelope current technology are hardly or not increased at all.
  • the structural integration of the Hüllstromdüsen in the atomizer can be achieved in the invention, for example, characterized in that the Hüllstromdüsen are arranged in the atomizer housing. However, there is also the alternative possibility that the Hüllstromdüsen are arranged in a shaping air ring or other integral component of the atomizer.
  • the invention encompasses the general technical teaching of influencing the evaporation conditions and thus the change in the solids content during application in that a defined microclimate is generated in the surroundings of the coating agent jet so that costly air conditioning of the entire paint booth is less important or even eliminated ,
  • the invention is not limited to those paint shops in which to dispense with a conventional air conditioning of the spray booth, but also includes painting, where in addition to the creation of a defined microclimate in the environment of the coating agent jet air conditioning of the entire spray booth takes place.
  • the invention provides an atomizer which, in addition to an application element (for example a bell cup) for applying a coating agent jet to a component to be coated, has at least one envelope flow nozzle via which a conditioned envelope flow is emitted which at least partially surrounds the coating agent jet and thereby in the environment of the coating agent jet defined microclimate generated, which provides for predetermined evaporation conditions.
  • the conditioned envelope stream surrounds the coating agent jet in a jacket-like manner over its entire circumference and / or over its entire length between the application element and the component to be coated.
  • the sheath flow is heated, cooled, dried or moistened with respect to the ambient air. Furthermore, there is the possibility of a combination of heating or cooling on the one hand and drying or humidifying the envelope flow on the other hand.
  • the heating of the sheath flow is preferably carried out by an air heater, which is preferably structurally separated from the atomizer.
  • an air heater which is preferably structurally separated from the atomizer.
  • the heating of the enveloping current is preferably carried out for reasons of explosion protection not by electric heating elements in the atomizer, but by the above-mentioned separate air heater.
  • the sheath flow has an outlet temperature of more than + 40 ° C. and / or less than + 100 ° C. directly at the sheath flow nozzle, wherein any intermediate values within this range of values are possible.
  • the outlet temperature of the enveloping stream can here be varied depending on the coating agent used. For example, water evaporates less as a solvent as organic solvents, so that the outlet temperature of the enveloping stream can be increased in the application of water-based paint over the application of solvent-based lacquer.
  • the sheath flow preferably has a volume flow of more than 500 l / min and / or less than 2500 l / min, with any intermediate values within this interval being possible.
  • the sheath flow preferably consists of air, which are available anyway in the form of compressed air in paint shops. In the context of the invention, however, it is also possible to use a gas other than air for the sheath flow. Gases with a greater heat capacity, a greater electrical insulation capacity and / or a higher moisture saturation limit than air are particularly suitable for this purpose.
  • the greater heat capacity offers the advantage here that the sheath flow only slightly loses its temperature after exiting the sheath flow nozzle, which ensures defined evaporation conditions.
  • a larger electrical insulation capacity is advantageous in an electrostatic atomizer because the insulating capacity of the sheath current prevents a discharge of the electrostatically charged coating agent particles and thereby provides a high application efficiency.
  • the sheath flow can therefore also consist, for example, of sulfur hexafluoride (SF 6 ) or inert gases (eg carbon dioxide (CO 2 ) and nitrogen).
  • SF 6 sulfur hexafluoride
  • CO 2 carbon dioxide
  • nitrogen nitrogen
  • the atomizer according to the invention preferably has an inner housing and an outer housing on, between the inner housing and the outer housing a Hüllstromzutechnisch for passing the air-conditioned enveloping flow to the Hüllstromdüse runs.
  • This has the advantage that the sheath flow is only relatively slightly cooled in the passage through the atomizer and therefore still has a sufficiently high temperature at the Hüllstromdüse.
  • the atomiser according to the invention is therefore preferably designed so that the sheath flow within the atomizer in the sheath current supply up to the sheath flow nozzle only by less 140 ° C, 120 ° C, 100 ° C, 90 ° C, 80 ° C, 70 ° C, 60 ° C, 50 ° C, 40 ° C, 30 ° C, 20 °, 10 ° C or less than 5 ° C is cooled.
  • connection flange of the atomizer with the flange connections provided there does not have to be changed.
  • the atomizer according to the invention has shaping air nozzles for the discharge of a shaping air jet, wherein the shaping air jet forms the coating agent jet.
  • the shaping air jet forms the coating agent jet.
  • an inner shaping air jet and an outer shaping air jet are provided, which offers greater flexibility in the shaping of the coating agent jet.
  • the outer shaping air nozzles simultaneously form the sheath flow nozzles.
  • the sheath flow nozzles are provided in addition to the shaping air nozzles and separated from them.
  • the shaping air nozzles are preferably mounted on the inside, while the jacket nozzles are mounted on the outside.
  • the sheath flow not only sheaths or sheaths the coating agent jet, but also the guide air flow, so that the guide air flow runs between the sheath flow and the coating agent jet.
  • This arrangement is advantageous because the jacket-shaped envelope of the coating agent jet is facilitated or made possible by the sheath flow in that the shaping air jet forms the coating agent jet.
  • the number of sheath flow nozzles is preferably greater than 20 and / or less than 60, with any intermediate values within this interval being possible.
  • the sheath flow nozzles preferably each have nozzle openings with a width or with a diameter of more than 1 mm and / or less than 8 mm.
  • the sheath flow nozzles therefore preferably have larger nozzle openings than the shaping air nozzles.
  • the envelope flow nozzle is designed as an annular gap nozzle.
  • the gap nozzle preferably has a gap width in the range of 0.1-1 mm, while the gap diameter is preferably in the range of 50-100 mm.
  • Such slit nozzles are as shaping air nozzles, for example EP 0 092 043 A2 known. The content of this document is therefore attributable to the structural design of the slit nozzle of the present description.
  • an application element used in the context of the invention is to be understood generally and also includes, for example, ultrasonic atomisers, airless devices and airmix devices.
  • the application element is a rotatable bell cup having a predetermined bell-shaped edge.
  • an axial distance of more than 5 mm and / or less than 100 mm preferably lies between the Hüllstromdüse and the Glockentellerkante.
  • an application element used in the context of the invention therefore has the meaning that a coating agent (for example wet paint or powder coating) can be applied to a component to be coated (for example a motor vehicle body part) by means of the application element.
  • a coating agent for example wet paint or powder coating
  • the Hüllstromdüsen can be angled in the circumferential direction of the bell cup and thus have a predetermined helix angle, the Hüllstromdüsen can be angled either in the direction of rotation of the bell cup or counter to the direction of rotation of the bell cup.
  • the helix angle of the sheath flow nozzles can in this case be in the range of 0-45 °, wherein in turn any intermediate values are possible.
  • the atomiser according to the invention can optionally be a powder atomizer or a wet paint atomizer.
  • the invention includes not only the above-described atomizer according to the invention as a single component, but also a painting device (eg, a painting robot or a paint shop) with such an atomizer.
  • a painting device eg, a painting robot or a paint shop
  • the painting device preferably has, in addition to the atomizer, an air-conditioning device for conditioning the enveloping flow, the air-conditioning device being connected downstream to the enveloping jet nozzle (s).
  • the air conditioning device may have a conventional air heater to heat the air flow.
  • the air conditioning device may have a cooling device which cools the enveloping flow.
  • the air conditioning device has a dehumidifying device, which dehumidifies the sheath flow.
  • the air conditioning device can therefore be constructed like a conventional air conditioning system.
  • the invention comprises an operating method for an atomizer according to the invention, in which, in addition to the delivery of a coating agent jet, a conditioned envelope stream is dispensed, which at least partially surrounds the coating agent jet.
  • the spatial position of the component surface to be coated is determined and the envelope current is influenced as a function of the determined spatial position.
  • the spatial position of the atomizer can be determined, since the atomizer is usually performed according to the spatial position of the component surface to be coated.
  • the spatial position of the atomizer can in turn be determined from the position control signals of the robot controller.
  • the temperature, the moisture content and / or the volume flow of the sheath flow can then be influenced.
  • an enveloping flow having a lower moisture content, a greater temperature and / or a larger volume flow is emitted than in the case of a coating of a substantially horizontal component surface.
  • the sheath flow can be adjusted such that the solids content of the coating agent jet increases by more than 5%, 10%, 25% or even 50% between the delivery to the application element and the impingement on the component surface to be coated.
  • FIG. 1 shows in simplified form a rotary atomizer 1, which is constructed largely conventional and can be used for example for painting automotive body panels.
  • the rotary atomizer 1 a conventional bell cup 2, which is rotatably mounted about a bell-plate axis 3 and is driven by a turbine 4. At the bell-shaped edge, the bell-shaped plate 2 emits a coating agent jet 5, wherein the coating agent jet 5 is shown here only schematically.
  • the rotary atomizer 1 has numerous inner shaping air nozzles 6, which are arranged concentrically around the bell-plate axis 3 and emit an inner shaping air jet 7 onto the outer surface of the bell plate 2, wherein the inner shaping air jet 7 forms the coating agent jet 5.
  • the rotary atomizer 1 has a plurality of outer shaping air nozzles 8, via which an outer shaping air jet 9 is dispensed, which additionally forms the coating agent jet 5.
  • the rotary atomizer 1 on numerous Hüllstromdüsen 10 which are also arranged concentrically around the Glockentellerachse 3 and deliver an air-conditioned envelope stream 11, which surrounds the coating agent jet 5 shell-shaped and thereby ensures defined evaporation conditions.
  • the exiting sheath flow 11 tears a side stream 12 of ambient air, wherein the entrained side stream 12 0-50% of the outflowing from the Hüllstromdüsen 10 sheath flow 11 accounts.
  • connection flange 13 The supply of the sheath flow 11, the coating agent and the shaping air takes place through a connection flange 13, to which two separate shaping air lines 14, 15 can be connected.
  • jacket power lines 16, 17, 18 and an optional envelope current line 19 can be connected to the connection flange 13 in order to supply the conditioned envelope current 11 to the rotary atomizer 1.
  • the sheath current lines 16-19 are connected to an air heater 20 and an air flow regulator 21, so that the volume flow and the temperature of the sheath flow 11 can be varied.
  • the supply of the enveloping flow 11 from the connection flange 13 to the enveloping flow nozzles 10 takes place by means of an enveloping flow passage between an inner housing 22 and an outer housing 23 of the rotary atomizer 1.
  • the number of sheath flow nozzles 10 may be in the range of 20 to 60, wherein the individual sheath flow nozzles 10 each have nozzle openings with a width of 1-8 mm.
  • the axial distance between the Hüllstromdüsen 10 and the Bell plate edge of the bell cup 2 can be between 5 and 100 mm.
  • FIG. 2a schematically shows the painting of a vertical component surface 24 by the rotary atomizer 1. Due to the vertical alignment of the component surface 24 is due to the force acting on the applied paint particles gravity g the risk of runners. In order to avoid such runners, the solids content of the coating agent jet 5 impinging on the vertical component surface 24 is purposefully increased, in which the temperature T1 of the sheath flow 11 from the air heater 20 (cf. Fig. 1 ) is specifically increased. As a result, the coating agent jet 5 impinging on the vertical component surface 24 contains less liquid solvent portions and therefore has less tendency to bleed. The stronger evaporation of the solvent components from the coating agent jet 5 into the surrounding enveloping flow 11 is represented here by block arrows.
  • FIG. 2b in contrast, the painting of a horizontal component surface 25 is represented by the rotary atomizer 1. Due to the horizontal alignment of the component surface 25, the risk of a running of the coating agent on the component surface 25 is lower, so that less liquid solvent components from the coating agent jet 5 must evaporate into the sheath flow 11. The sheath flow 11 therefore has in the painting of the horizontal Component surface 25 a smaller temperature T2 ⁇ T1 than in the painting of the vertical component surface 24.
  • FIG. 3 shows in a highly simplified form a block diagram of a painting device according to the invention with a robot controller 26 which controls a multi-axis painting robot 27 with position control data, wherein the painting robot 27 leads the rotary atomizer 1.
  • the position control data are also passed on by the robot controller 26 to a computing unit 28, which determines therefrom the inclination ⁇ of the component surface to be coated.
  • the inclination ⁇ of the component surface is then passed on to an envelope current controller 29, which influences the envelope current 11 as a function of the inclination ⁇ of the component surface.
  • the sheath flow controller 29 controls a sheath flow dryer 30, a sheath current heater 31 and a sheath flow valve 32.
  • the sheath flow 11 is in this case influenced in dependence on the inclination ⁇ of the component surface to be coated in such a way that bleeding of the coating agent on the component surface is prevented.
  • the coating stream is heated to a greater extent during a coating of vertically aligned component surfaces and dried than when coating horizontally aligned component surfaces.
  • the robot controller 26, the arithmetic unit 28 and the envelope current controller 29 can be integrated in a common electronic control unit 33. In this case, there is also the possibility that the robot controller 26, the arithmetic unit 28 and / or the envelope current controller 29 are implemented as software modules.
