Definitions
- the invention relates to a method for the functional control of a particular electrostatic series coating of workpieces such as vehicle bodies used in particular, e.g. mounted on a painting robot rotary atomizer and a corresponding coating system according to the preamble of the independent claims.
- High-rotation atomizers of the type considered here essentially consist of a rotating bell cup as a spray-off body and its drive. As drive usually find air-bearing air turbines use. Depending on the paint material and throughputs, the atomizers with speeds between 5000 and 100000 / min. operated.
- the lacquer sprayed off and atomized tangentially from the glove-box edge is emitted by a shaping air flow, which is arranged coaxially to the atomizer axis and comprises annular or annular gap arrangements arranged annularly behind the bell cup (EP 1 331 037 B1, WO 2008/061584 A1, etc.), and deflected by electrostatic field forces on the grounded substrate to be coated and formed into a spray jet.
- An additional secondary paint atomization on the edge of the bell-shaped plate is also effected with shaping air.
- the directing air quantity is regulated as a function of target values.
- the quality criteria which are generally the most important are the layer thickness and the uniformity of the applied lacquer layer.
- the quality requirements are still rising with the desire for ever-increasing productivity and higher area performance without sacrificing quality and the availability of improved paint materials.
- the required layer uniformity has hitherto been achieved inter alia because the paint is applied in several overlapping layers. In future processes with less effort or increase in productivity due to higher coating speeds, correspondingly higher demands are placed on the quality of the layers.
- the resulting layer thickness depends on the high rotation sputtering significantly from the area distribution of the paint due to the width of the spray. Since the area of the paint application decreases with a constant quantity of paint in the square ratio with reduction of the spray jet width, the layer thickness increases in inverse ratio, so that variations of the layer thickness by several 100% are possible and partly also used.
- the spray jet width which determines the layer formation is controlled by the direction and speed of the already mentioned shaping air flow. Incorrect air flow results in undesirable deviations from the intended layer formation. While too thick a spray layer on too small an area results in too thick a layer, the reverse case results in too low Sprühstrahleinschnürung. Furthermore, the cross-sectional shape of the applied layer is distorted by undesired shaping air flows.
- the point of impact of the paint particles on the workpiece is not on the extended axis of rotation of the bell cup, so concentric to the central axis of the air nozzles.
- the spray jet width can change irrespective of the position of the air nozzle axes and of the bell-shaped blade, because the spray nozzles consist of a multiplicity of individual nozzles
- High-speed discharge air at its outer and inner lateral surfaces generates a considerable friction with respect to the static ambient air and thus moves parts of the ambient air in a direction parallel to the shaping air.
- the resulting air deficits on the outer surface can be easily compensated by the influx of ambient air, forming a negative pressure inside the steering cone, which leads to deformation, ie bundling of the steering cone. This deformation then determines the spray jet width.
- the spray jet width is set during the coating process by the regulated shaping air flow in accordance with the respective specifications regarding workpiece geometry and process conditions. This desired controllability of
- Spray jet width depends essentially on what negative pressure can be achieved within the flow cone.
- the higher flow velocities required for this purpose also bring about a better deflection of the paint particle stream at the bell-shaped edge.
- the Lenkluft internal pressure is thus a highly functional determinant of the transport and the local deposition of the paint particle stream. Normally, the internal pressure represents the directing air flow, the flow velocity and the flow geometry.
- the steering internal pressure and the steering air / internal pressure characteristic ie the course of the internal pressure of the shaping air flow as a function of the measured per unit time Lenkluftmenge, also an identification criterion for perfect condition of the shaping air nozzle assembly of the atomizer, in particular the opening cross-section, the geometric uniformity and proper mounting of the holes or slots of the shaping ring, in addition to manufacturing tolerances, damage or assembly errors such as swapping may also be affected by contamination of two existing different Lenkluft Vietnameseen or missing or defective seals in the atomizer.
- the effect on the steering internal pressure which is reduced by all such errors, is based significantly on the existing possibilities of balancing the high pressure difference between the external and internal pressure.
- the pressure difference is also compensated by air flow from the overpressure zone in front of the workpiece surface, whereby the spray cone can be wider.
- the spray cone can be wider.
- the flow resistance of the workpiece surface of the overpressure and thus the mentioned air flow are reduced, so that the corresponding decreasing internal pressure leads to a "folding" of the spray and thus to much smaller beam diameters.
- a halving of the beam diameter and thus a quadrupling of the local paint deposit can be observed. Although this effect may be useful in certain cases, it is undesirable if it is incalculable.
- the above-mentioned effects can lead to unwanted reproducibility errors and quality defects during commissioning of the coating system and in the production process.
- the invention aims to provide a method or a coating system with which simple, objective and reliable manner with little effort an almost holistic function control of rotary atomizers both before and during the coating operation (online) is possible.
- the invention is based on the finding that a high and stable pressure difference between the pressure areas inside and outside the shaping air flow is a clear characteristic of a fault-free overall system of the rotary atomizer. The same applies to a steep long Lenkluft / internal pressure characteristic. It may also be sufficient to measure only the internal pressure of the shaping air flow or the pressure in the negative pressure area adjacent to the shaping air flow, that is to say the pressure difference with respect to the known air pressure in the vicinity of the atomizer.
- the shaping air flow here means the gas flow generated in a manner known per se by the atomizer with an arrangement of shaping air openings or nozzles of the atomizer, wherein instead of air theoretically another gas could also be used.
- the flow (more or less cone-shaped in the typical case) is located outside the atomizer at the end face, with which the coating material sprayed off from the rotating bell cup of the atomizer is applied.
- the respective pressure can be measured with the help of possibly only one, but in any case less pressure measuring devices and correspondingly little effort, preferably with pressure sensors that can be permanently installed inside and / or outside the atomizer or movable outside the atomizer. NEN.
- the rotary atomizer or the pressure sensor can be brought into a predetermined defined measuring position, wherein the rotary atomizer is positioned for example by the painting robot to which it is mounted, while a movable sensor, for example manually or by a particular automatically controlled handling device or auxiliary robot can be positioned.
- a movable sensor for example manually or by a particular automatically controlled handling device or auxiliary robot can be positioned.
- a particular advantage of the low-pressure measurement according to the invention is that it can identify the essential Zerstäuberfunktionen as steering amount of air geometry of the shaping air nozzles and re ⁇ ale error situation without simultaneous paint atomization, without being influenced by Eigenschaf- th of the coating material and without appropriate
- the measurement can be done manually or preferably fully automatically without intervention in the atomizer and in its supply line system.
- the measurement information is always available without delay, so that immediately initiated appropriate measures in the event of a fault and consequently, for example, for production control during commissioning of the coating system and especially during the ongoing production process (online) quality defects. layered workpieces and corresponding costs can be avoided by malfunction.
- the quality of production is therefore supported preventively, and indeed much more objectively than in previous practice, in particular independent of subjective factors such as qualification and availability of skilled personnel.
- the measured values are also independent of a special test setup and test location and thus objectively and with each other comparable.
- FIG. 1 shows the flow field at the end face of a rotary atomizer.
- Fig. 2 shows possible locations for the positioning of pressure sensors in the rotary atomizer and outside in the negative pressure areas of its shaping air flow;
- Fig. 3 examples of the positioning of pressure sensors outside of the rotary atomizer.
- a rotary atomizer 10 the coating of the workpiece facing frontal part of a rotary atomizer 10 is shown schematically, consisting essentially of the bell cup 11 and a guide air ring not shown in detail, whose concentric to the axis of rotation arrangement of Lenkluftdüsen generates the shaping air flow 12 in a conventional manner.
- the illustrated shaping air cone corresponds to the shape of the tracks of the sprayed tangentially from the bell cup 11 paint particles, so the spray jet.
- the rotary atomizer 10 can be of any known type and, in particular, for the vehicle body painting type (cf., for example, the already mentioned WO 2008/061584 A1) and therefore requires no further description. As already explained, forms in the production of
- Lenkluftströmung 12 due to the friction between the fast-flowing shaping air and the previously resting ambient air on the outer surface of the shaping air flow 12 an outer air friction area 13 and on its inner surface an inner Heiliri- area 14, whereby outside the Lenkluftströmung in the vicinity of an outer negative pressure area 17 and within the Lenkluftströmung required for the desired bundling of the flow inner negative pressure area 18 are formed.
- Partial pressure compensation takes place by means of an external compensation flow indicated at 15 and an internal compensation flow 16.
- arbitrary measuring devices can be used per se for measuring the pressure values in the vacuum regions 17 and / or 18 according to the invention.
- Some embodiments of suitable locations for positioning pressure sensors are shown in FIG. Accordingly, it may be appropriate to permanently install in the rotary atomizer 10, a pressure sensor 21 for measuring the external negative pressure and / or a pressure sensor 22 for measuring the internal negative pressure of the steering ⁇ air flow 12.
- the sensors with the negative pressure areas 17 and 18 through corresponding pressure measuring channels 21 'and 22' are connected, of which the channel 21 'as shown in the vicinity of the bell cup in the Circumferential surface of the atomizer housing can open, while the channel 22 ', for example, open centrally in the workpiece facing end surface of the bell cup and there can in particular match the Lackaustrittsweg through which preferably no paint flows in the pressure measurement.
- external pressure sensors 23 and 24 can be arranged directly in the negative pressure areas 17 and 18 for measuring the respective pressure there.
- the pressure values measured by the sensors 21 - 24 can be supplied in the form of suitable signals to a measuring system 26 shown schematically, evaluated and compared with predetermined reference values for error-free atomizer functions.
- a measuring system 26 shown schematically, evaluated and compared with predetermined reference values for error-free atomizer functions.
- the measured values of the pressure sensors 21 and 22 can be transmitted to the measuring system 26 as pneumatic signals.
- FIG. 2 Various possibilities for the arrangement of external pressure sensors 23 or 24 (FIG. 2) in the mentioned negative-pressure regions are shown by way of example in FIG.
- the depiction 3A shows a pressure sensor 24a, which can be installed, in particular for measuring the external negative pressure, with a spacer 25a fixed to the wall 30 of the spray booth or to another stationary component of the coating system considered here , To measure the pressure value, the rotary atomizer can be automatically brought by its coating robot into the correct measuring position relative to the defined position of the pressure sensor 24a.
- the illustration 3B shows an external pressure sensor 24b, which is also in particular for measuring the external negative pressure firmly and expediently can be installed with a spacer 25b on a part 31 of the painting robot itself, ie in particular on a part of the robot with the forearm and wrist reachable part defined position.
- the representation 3C shows a manually movable and preferably transportable pressure probe 24c, which can be introduced into the shaping air flow, for example for measuring the pressure in the inner negative pressure region of the shaping air flow.
- a preferably automatically controlled handling device could also be used for this purpose.
- pressure probes against the direct congestion effect of the high flow velocities of the shaping air.
- a suitable possibility for this purpose is, for example, the sheathing of the pressure sensors with air-permeable, but flow-breaking sintered bodies made of metal or plastic.
- known and customary pressure probes can be used.
- a typical application example of the invention is a regular contamination control in the production process.
- Contamination with fixed dried paint mist can change the opening cross-section of shaping air nozzles in such a way that weakening or changing the direction of the air outlet occurs.
- the weakening of the desired shaping air flow causes a reduction of the negative pressure in the interior of the shaping air flow, whereby the bundling of the paint flow in the direction of the workpiece is weakened and thus the spray jet width is reduced.
- the distribution of lacquer deposition on the workpiece widens with a correspondingly smaller layer thickness. In edge areas of the workpiece, higher edge losses of paint material occur because parts of the Streams miss the surface.
- the atomizer can be introduced at regular time intervals, for example by the painting robot to a permanently installed pressure sensor such as 23 in Fig. 2 so that the internal pressure in the shaping air flow can be measured. Having previously measured and stored the proper atomizing function setpoints, it is possible to compare later with the current conditions to be tested, and thus to detect faults and initiate appropriate troubleshooting procedures, in the example considered for cleaning the shaping air nozzles.
