Definitions

  • the invention relates to a coating device for coating, in particular painting, motor vehicle body components. Furthermore, the invention relates to a corresponding coating method.
  • Figure 1 shows a cross-sectional view through a conventional painting system for painting motor vehicle body components.
  • the motor vehicle body components to be painted are transported on a conveyor 1 at right angles to the plane of the drawing through a paint booth 2, in which the motor vehicle body components are then painted in a conventional manner by painting robots 3, 4.
  • the painting robots 3, 4 have several pivoting robot arms and each guide an application device, such as a rotary atomizer, an air atomizer, or a so-called airless device, via a multi-axis robot wrist axis.
  • an application device such as a rotary atomizer, an air atomizer, or a so-called airless device
  • a disadvantage of these known application devices is the suboptimal application efficiency, so that a portion of the sprayed paint, referred to as overspray, does not land on the vehicle body component to be painted and must be removed with the booth air from the paint booth 2.
  • Above the paint booth 2 there is therefore a so-called plenum 5, from which air is introduced downwards through a ceiling 6 of the paint booth 2 in the direction of the arrow into the paint booth 2.
  • the booth air then flows downwards from the paint booth 2, along with the overspray it contains, into a washout 7 located below the paint booth 2, where the overspray is removed from the booth air and bound to water.
  • the known application devices cause high investment costs for the necessary washout and the necessary explosion protection due to their unsatisfactory application efficiency and the resulting overspray.
  • EP 1 884 365 A1 discloses an application head for applying paint to an object surface, the application head comprising at least one fluid supply channel and at least one nozzle outlet for paint.
  • the at least one nozzle is arranged in groups or arrays, each of which has means for generating a pressure pulse in the paint such that a small amount of paint is ejected from the at least one nozzle. The speed and timing of the paint ejection can be controlled separately for each of the plurality of nozzles in the application head.
  • the invention encompasses the general technical teaching of using an application device with such a high application efficiency that a washout, which is conventionally used to wash out the overspray from the booth air, can be dispensed with.
  • a washout which is conventionally used to wash out the overspray from the booth air
  • One advantage of the coating device according to the invention is that a separate washout is dispensed with.
  • the invention is not limited to painting systems that have no washout at all. Rather, the use of application devices with a higher application efficiency makes it possible to reduce the dimensions of the washout if complete dispensing is not possible.
  • the print head can eject the coating agent either in individual coating agent droplets or continuously. Furthermore, within the scope of the invention, it is possible for some of the coating agent nozzles of the print head to eject the coating agent continuously, while another part of the coating agent nozzles of the print head ejects the coating agent in individual coating agent droplets.
  • the print head in the coating device according to the invention has a significantly larger area coating capacity, which is greater than 1 m 2 /min. and preferably greater than 2 m 2 /min., 3 m 2 /min., or 4 m 2 /min.
  • the printhead of the coating device according to the invention must also be capable of applying liquid coatings containing solid coating components, such as pigments and so-called metallic flakes (mica).
  • solid coating components such as pigments and so-called metallic flakes (mica).
  • the individual coating nozzles of the printhead are therefore sized to match the solid coating components, so that the printhead can also apply coatings containing the solid coating components.
  • the application device is preferably arranged in a paint booth in which the components are coated with the coating agent.
  • paint booths are known from the prior art and therefore need not be described in detail.
  • the print heads used as application devices within the scope of the invention have a significantly higher application efficiency than conventional application devices, such as rotary atomizers.
  • the washout located below the paint booth can therefore be dimensioned much smaller than in conventional painting systems with rotary atomizers as application devices.
  • the high application efficiency of the print heads used as application devices even makes it possible to completely dispense with washout or other complex filter measures, such as dry separation or similar, below the paint booth. In this case, simple filters that are replaced or cleaned cyclically (e.g., weekly, monthly, semi-annually, or annually) are sufficient.
  • the high application efficiency of the print heads used as application devices within the scope of the invention eliminates the need for explosion protection measures according to the relevant statutory ATEX guidelines, as less overspray is generated and therefore no potentially explosive atmosphere is created during operation. In one embodiment of the invention, therefore, no explosion protection is provided in the paint booth.
  • the coating device according to the invention also preferably provides an air extraction system that extracts the booth air from the paint booth, with the extraction preferably taking place downwards.
  • the booth air is preferably extracted through an air filter that filters the overspray from the booth air.
  • the air filter can be designed, for example, as a filter ceiling arranged on the floor of the paint booth, so that the booth air is extracted downwards from the paint booth through the filter ceiling.
  • the air settling velocity in the paint booth can be lower than in conventional paint systems that use, for example, rotary atomizers as application devices.
  • the air settling velocity in the paint booth can therefore be less than 0.5 m/s, 0.4 m/s, 0.3 m/s, 0.2 m/s, or 0.1 m/s.
  • At least one color changer is assigned to the print head, which is connected to the print head on the output side and is preferably supplied with different coating agents on the input side, so that the color changer selects one of the coating agents and feeds the print head with the selected coating agent.
  • the color changer can be supplied with various effect paints on the input side, such as special paints, metallic paints or mica paints.
  • the color changer feeds a group of several coating agent nozzles with the same coating agent on the output side, wherein the coating agent nozzles can be arranged, for example, in a row, for example in a line or a column.
  • a color mixer can be arranged upstream of the color changer on the input side, which is supplied with different colored coating agents in the primary colors of a color system (e.g., CMYK color system).
  • the color mixer can then mix a desired color from the various primary colors of the respective color system and feed it to the color changer for selection.
  • the color changer is preferably supplied with at least one effect paint, for example, a mica paint, a metallic paint, and/or a special paint.
  • the color changer can then either select the color mixed by the color mixer or access one of the effect paints.
  • the coating nozzles in the print head can be arranged in rows, for example, in rows and columns.
  • the coating nozzles are arranged in the print head in a matrix.
  • each of the individual coating agent rows prefferably be assigned a basic color (e.g. cyan, magenta, yellow, black) so that the coating agent nozzles of a row apply the same color.
  • a basic color e.g. cyan, magenta, yellow, black
  • all coating agent nozzles of the print head are connected to a single coating agent supply line and therefore apply the same coating agent.
  • the coating agent nozzles of the print head it is possible for some of the coating agent nozzles of the print head to be connected to a first coating agent supply line, while a second part of the coating agent nozzles of the print head is connected to a second coating agent supply line, so that the print head can apply two different coating agents.
  • the coating agent nozzles in the individual nozzle rows are alternately connected to one coating agent supply line or to the other coating agent supply line.
  • the print head has at least one separate coating nozzle that applies only effect paint containing effect particles. Furthermore, the print head preferably has at least one additional coating nozzle that applies normal paint that does not contain effect particles. The various coating nozzles can then be adapted accordingly.
  • the effect particles e.g., metallic, mica, etc.
  • the effect particles are applied to the object using a separate coating nozzle. This allows effects to be applied to the object in a very targeted manner and with local variations. In some cases, effects can also be created that are unimaginable today. With the new inkjet technology, it is possible to place the effect particles, for example, only on the surface of the layer.
  • a major advantage of the invention is that the solution according to the invention makes it possible for the first time to coat an entire body with sufficient surface coverage, but also to print specific details and graphics.
  • the coating nozzles in the print head are preferably arranged in a matrix in several rows and columns.
  • the individual coating nozzles of the print head are essentially the same size.
  • the adjacent nozzle rows can be offset from one another in the longitudinal direction, in particular by half a nozzle width, which enables maximum packing density of the coating nozzles in the nozzle head.
  • the individual nozzle rows are preferably aligned transversely, in particular at right angles to the feed direction of the nozzle head.
  • the "mixing chamber” can be a mixing chamber, a piece of hose, or a mixing system (e.g., a Keenix mixer).
  • a mixing system e.g., a Keenix mixer.
  • the challenge is the very precise dosing of the individual components to achieve the exact color shade. Therefore, a color sensor for controlling the dosing unit can be useful.
  • the above-mentioned guide track may also be a separate track applied solely for guidance purposes and may, for example, comprise a normally invisible color that is only visible to the sensor when illuminated with ultraviolet (UV) or infrared (IR) light.
  • UV ultraviolet
  • IR infrared
  • a special feature of the painting system according to the invention is that the painting robots 3, 4 do not use rotary atomizers as application devices, but rather print heads 8, 9, which have a significantly higher application efficiency of more than 95% and therefore generate significantly less overspray.
  • this offers the advantage that the conventional painting system according to Figure 1 existing leaching 7 can be dispensed with.
  • an air extraction system 10 is located below the painting booth 2, which extracts the booth air downwards from the painting booth 2 through a filter ceiling 11.
  • the filter ceiling 11 filters out the slight overspray present in the booth air without the need for the washout system 7 as in the conventional painting system.
  • the print heads 8, 9 operate like conventional print heads according to the piezo principle, but the surface coating performance of the print heads 8, 9 is significantly greater compared to conventional print heads so that the motor vehicle body components can be painted at a satisfactory working speed.
  • Figure 3A shows a coating agent nozzle 12, which is arranged in each of the print heads 8, 9 alongside numerous other coating agent nozzles, wherein the coating agent nozzle 12 is supplied with the coating agent to be applied by a color changer 13.
  • the color changer 13 On the input side, the color changer 13 is connected to a total of seven coating agent supply lines, from which the color changer 13 can select one to supply the coating agent to the coating agent nozzle 12.
  • the other three coating agent supply lines of the color changer 13, in contrast, are used to supply a metallic paint, a mica paint, and a special paint.
  • the desired color shade of the coating agent is mixed on the motor vehicle body component to be coated, whereby either a temporal or a spatial mixing is possible.
  • droplets of coating agent in the basic colours C, M, Y and K are applied one after the other in the desired colour ratio, so that the droplets of coating agent then mix on the motor vehicle body component to be coated.
  • Figure 3B shows a modification of the embodiment according to Figure 3A , showing a nozzle row with four coating agent nozzles 14.1-14.4 and four color changers 15.1-15.4.
