Description

Die Erfindung betrifft eine Anlage zum Beschichten, insbesondere zum Lackieren, von Gegenständen, insbesondere von Fahrzeugkarosserien, mit

  1. a) einer Behandlungskabine, in welcher die Gegenstände mit Beschichtungsmaterial beaufschlagbar sind;
  2. b) einem Luftsystem, mittels welchem ein Kabinenluftstrom durch die Behandlungskabine hindurch erzeugbar ist, welcher entstehende Overspraypartikel des Beschichtungsmaterials aufnimmt und abführt.
The invention relates to a system for coating, in particular for painting, of objects, in particular of vehicle bodies, with
  1. a) a treatment cabin, in which the objects can be acted upon with coating material;
  2. b) an air system, by means of which a cabin air flow through the treatment cabin can be generated, which receives and dissipates the resulting overspray particles of the coating material.

Bei der manuellen oder automatischen Applikation von Lacken auf Gegenstände wird ein Teilstrom des Lackes, der im Allgemeinen sowohl Festkörper und/oder Bindemittel als auch Lösemittel enthält, nicht auf den Gegenstand appliziert. Dieser Teilstrom wird in der Fachwelt "Overspray" genannt. Der Overspray wird von dem Kabinenluftstrom in der Behandlungskabine erfasst und einer Abscheidung zugeführt, sodass die Luft gegebenenfalls nach einer geeigneten Konditionierung wieder in die Beschichtungskabine zurückgeleitet werden kann.In the case of manual or automatic application of lacquers to objects, a partial flow of the lacquer, which generally contains both solids and / or binders and solvents, is not applied to the article. This partial flow is called "overspray" in the professional world. The overspray is detected by the cabin air flow in the treatment cabin and fed to a separation, so that the air can optionally be returned to the coating booth after a suitable conditioning.

Um reproduzierbare Lackierergebnisse zu erhalten, ist es in Lackierkabinen normalerweise wünschenswert, dass die Strömungsgeschwindigkeit, mit welcher die Kabinenluft von oben nach unten durch die Lackierkabine hindurch strömt, über die Fläche der Kabine weitgehend konstant ist.In order to obtain reproducible coating results, it is normally desirable in spray booths that the flow rate at which the cabin air flows from top to bottom through the spray booth is substantially constant over the area of the booth.

In jüngerer Zeit haben sich Abscheidesysteme etabliert, die zwar Overspray effizient aus der Kabinenluft herausfiltern, im Laufe des Betriebs den Luftdurchgang jedoch lokal unterschiedlich hemmen, da lokale Verschmutzungen oder Verstopfungen auftreten können. Solche Systeme sind beispielsweise Filtersysteme oder elektrostatisch arbeitende Lackabscheider.In recent times, deposition systems have been established that efficiently filter overspray from the cabin air, but in the course of operation, the air passage is locally different inhibit, as local soiling or blockages may occur. Such systems are, for example, filter systems or electrostatic paint separators.

In solchen Fällen ist ein homogenes Strömungsprofil aufgrund lokal unterschiedlicher Strömungsgeschwindigkeiten der Kabinenluft nicht mehr über die Betriebsdauer gewährleistet.In such cases, a homogeneous flow profile is no longer guaranteed over the service life due to locally different flow velocities of the cabin air.

Die Praxis hat gezeigt, dass in anderen Fällen ein inhomogenes Strömungsprofil der Kabinenluft mit lokal unterschiedlichen Strömungsgeschwindigkeiten auch Vorteile mit sich bringen kann. Wenn z.B. eine Fahrzeugkarosserie von Kabinenluft umströmt wird, kann die Strömungsgeschwindigkeit der Kabinenluft im Bereich der Seiten der Fahrzeugkarosserie gegenüber der Strömungsgeschwindigkeit im Bereich oberhalb der Fahrzeugkarosserie erhöht werden, da an den Seiten der Fahrzeugkarosserie bei der Applikation mehr Overspray erzeugt wird.Practice has shown that in other cases an inhomogeneous airfoil profile of the cabin air with locally different flow velocities can also bring advantages. If e.g. If a vehicle body is surrounded by cabin air, the flow rate of the cabin air in the area of the sides of the vehicle body can be increased in relation to the flow speed in the region above the vehicle body because more overspray is generated on the sides of the vehicle body during application.

Die Strömungsgeschwindigkeit der Kabinenluft kann dann mit größerem Abstand von der Fahrzeugkarosserie wieder verringert werden, da dort weniger Overspray anfällt. Wenn dann im Bereich der Kabinenwände wieder größere Strömungsgeschwindigkeiten vorliegen, können Verschmutzungen an der Kabinenwand verhindert oder zumindest gering gehalten werden.The flow rate of the cabin air can then be reduced again with a greater distance from the vehicle body, since there is less overspray. If then in the area of the cabin walls again greater flow velocities, soiling on the cabin wall can be prevented or at least kept low.

Es ist nun Aufgabe der Erfindung, eine Anlage der eingangs genannten Art zu schaffen, welche diesen Gedanken Rechnung trägt.It is an object of the invention to provide a system of the type mentioned, which takes into account this idea.

Diese Aufgabe wird bei einer Anlage der eingangs genannten Art dadurch gelöst, dass

  • c) eine Strömungseinrichtung vorhanden ist, mittels welcher das Strömungsprofil des Kabinenluftstroms beeinflussbar ist.
This object is achieved in a system of the type mentioned in that
  • c) a flow device is present, by means of which the flow profile of the cabin air flow can be influenced.

Das Strömungsprofil des Kabinenluftstroms wird erfindungsgemäß also nicht durch die baulichen Gegebenheiten vorgegeben, sondern kann durch die Strömungseinrichtung gezielt verändert und eingestellt werden. Hierdurch kann sowohl ein inhomogenes Strömungsprofil homogenisiert werden, so dass die Kabinenluft über die Fläche der Kabine mit weitgehend gleicher Strömungsgeschwindigkeit strömt, als auch gezielt ein inhomogenes Strömungsprofil erzeugt werden, wie es oben beschrieben wurde.The flow profile of the cabin air flow is therefore not predetermined by the structural conditions according to the invention, but can be selectively changed and adjusted by the flow device. In this way, both an inhomogeneous flow profile can be homogenized, so that the cabin air flows over the surface of the cabin with substantially the same flow rate, as well as an intentionally generated an inhomogeneous flow profile, as described above.

Dabei ist es vorteilhaft, wenn die Strömungseinrichtung derart eingerichtet ist, dass in dem Kabinenluftstrom wenigstens die Strömungsgeschwindigkeit eines Einzelstroms beeinflussbar ist.It is advantageous if the flow device is set up such that at least the flow velocity of a single stream can be influenced in the cabin air flow.

Der Kabinenluftstrom kann als Ganzes aus einer Kombination von Einzelströmen gebildet sein, die nicht alle den gleichen Querschnitt haben müssen. So kann die oben angesprochene Verringerung der Strömungsgeschwindigkeit der Kabinenluft im Dachbereich einer Fahrzeugkarosserie erhalten werden, indem ein Einzelstrom mit rechteckigem Querschnitt über dem Dach der Fahrzeugkarosserie erzeugt wird, der von einem rechteckringförmigen Einzelstrom umgeben ist. Die Strömungseinrichtung sorgt dann dafür, dass die Strömungsgeschwindigkeit des mittleren, rechteckigen Einzelstroms kleiner ist als die des umgebenden Einzelstroms.The cabin air flow can be formed as a whole from a combination of individual streams, which need not all have the same cross-section. Thus, the above-mentioned reduction in the flow rate of the cabin air in the roof area of a vehicle body can be obtained by generating a single flow of rectangular cross-section over the roof of the vehicle body, which is surrounded by a rectangular ring-shaped single stream. The flow device then ensures that the flow velocity of the average, rectangular individual flow is smaller than that of the surrounding individual flow.

Vorzugsweise ist die Strömungseinrichtung derart eingerichtet, dass in dem Kabinenluftstrom die Strömungsgeschwindigkeiten mehrerer Einzelströme beeinflussbar sind.Preferably, the flow device is set up such that the flow velocities of a plurality of individual streams can be influenced in the cabin air flow.

Es ist günstig, wenn die Strömungseinrichtung zur Erzeugung jedes Einzelstroms eine Strömungseinheit umfasst.It is favorable if the flow device comprises a flow unit for generating each individual flow.

Bei einer ersten Alternative kann eine Strömungseinheit durch einen Ventilator (52) ausgebildet sein.In a first alternative, a flow unit may be formed by a fan (52).

Dabei ist es vorteilhaft, wenn der Ventilator so angeordnet ist, dass Kabinenluft über den Ventilator in die Behandlungskabine eingeblasen wird.It is advantageous if the fan is arranged so that cabin air is blown through the fan into the treatment cabin.

Bei einer Variante kann der Ventilator auch so angeordnet sein, dass dieser Kabinenluft aus der Behandlungskabine absaugt.In a variant, the fan may also be arranged so that this sucks cabin air from the treatment cabin.

Bei einer zweiten Alternative kann eine Strömungseinheit durch eine Strömungsklappe gebildet sein.In a second alternative, a flow unit may be formed by a flow flap.

Dabei ist die Strömungsklappe dann vorzugsweise so angeordnet, dass Kabinenluft über die Strömungsklappe in die Behandlungskabine eintritt.The flow flap is then preferably arranged so that cabin air enters the treatment cabin via the flow flap.

Als Variante kann hier vorgesehen sein, dass die Strömungsklappe so angeordnet ist, dass Kabinenluft über die Strömungsklappe aus der Behandlungskabine austritt.As a variant, it can be provided here that the flow flap is arranged so that cabin air exits via the flow flap from the treatment cabin.

Dieser Kabinenluftstrom bildet ein Strömungsprofil in dem Lackiertunnel 8 aus.The spray booth 6 comprises an overhead painting tunnel 8, which is bounded by vertical side walls 10 and a horizontal cabin ceiling 12, but is open at the end faces. In addition, the paint tunnel 8 is open at the bottom in such a way that overspray laden cabin exhaust air can flow down. The cabin ceiling 12 forms the lower boundary of an air supply space 14, which is part of an air system not provided with a reference numeral, by means of which a cabin air flow can be generated through the coating booth, which receives and discharges resulting overspray particles of the coating material. This cabin air flow forms an airfoil in the painting tunnel 8.

Auf Höhe der Kabinendecke 12 ist außerdem eine Strömungseinrichtung 16 angeordnet, mittels welcher das Strömungsprofil des Kabinenluftstroms beeinflusst werden kann; hierauf wird weiter unten noch im Detail eingegangen. Die Strömungseinrichtung 16 ist hier in die Kabinendecke 12 integriert.At the height of the cabin ceiling 12 also a flow device 16 is arranged, by means of which the flow profile of the cabin air flow can be influenced; This will be discussed in detail below. The flow device 16 is integrated here in the cabin ceiling 12.

Oberhalb einer unteren Öffnung 18 des Lackiertunnels 8 ist ein Stahlgerüst 20 angeordnet, welches ein an und für sich bekanntes Fördersystem 22 trägt, auf welches hier nicht näher eingegangen wird. Mit diesem können zu lackierende Fahrzeugkarosserien 4 von der Eingangsseite des Lackiertunnels 8 zu dessen Ausgangsseite transportiert werden. Im Inneren des Lackiertunnels 8 befinden sich Applikationseinrichtungen in Form von mehrachsigen Applikationsrobotern 24, wie sie an und für sich bekannt sind und welche vorliegend nur schematisch gezeigt sind. Mittels der Applikationsroboter 24 können die Fahrzeugkarosserien 4 mit Lack beschichtet werden.Above a lower opening 18 of the painting tunnel 8, a steel frame 20 is arranged, which carries a known per se conveyor system 22, which will not be discussed here. With this vehicle body 4 to be painted can be transported from the input side of the painting tunnel 8 to its output side. Inside the painting tunnel 8 are application devices in the form of multi-axis application robots 24, as they are known per se and which are shown here only schematically. By means of the application robot 24, the vehicle bodies 4 can be coated with lacquer.

Die untere Öffnung 18 des Lackiertunnels 8 ist durch einen begehbaren Gitterrost 26 abgedeckt. Unterhalb der Gitterrostes 26 befindet sich ein Anlagenbereich 28, in welchem die von der Kabinenluft mitgeführten Overspraypartikel von der Kabinenluft getrennt werden.The lower opening 18 of the painting tunnel 8 is covered by a walk-on grating 26. Below the grid 26 there is a plant area 28 in which the overspray particles carried by the cabin air are separated from the cabin air.

Aus dem Luftzuführraum 14 strömt also Luft nach unten durch den Lackiertunnel 8 hindurch zu dem Anlagenbereich 28, wobei die Luft im Lackiertunnel 8 vorhandenen Lack-Overspray aufnimmt und mit sich führt.From the air supply chamber 14 so air flows down through the paint tunnel 8 through to the plant area 28, wherein the air in the paint tunnel 8 receives existing paint overspray and leads with it.

Der Anlagenbereich 28 umfasst einen Strömungsbereich 30, in den die mit Overspray beladene Kabinenluft zunächst einströmt und welcher hierzu nach oben zur Lackierkabine 6 hin offen, jedoch seitlich von Luftleitblechen 32 begrenzt ist. Die Luftleitbleche 32 sind so angeordnet, dass ein Sammelkanal 34 gebildet ist, der sich nach unten hin verjüngt. Dieser Sammelkanal 34 mündet in einen Luftleitkanals 36, in den die mit Overspraypartikeln beladene Kabinenluft zunächst insgesamt vertikal nach unten einströmt.The plant area 28 comprises a flow area 30, into which the cabin air laden with overspray first flows and which, for this purpose, is open towards the paint booth 6, but is delimited laterally by air baffles 32. The air baffles 32 are arranged so that a collecting duct 34 is formed, which tapers towards the bottom. This collection channel 34 opens into an air duct 36 into which the cabin air laden with overspray particles initially flows in total vertically downwards.

Der Luftleitkanal 36 lenkt die Kabinenluft dann um 90° in die Horizontale um und umfasst eine Mehrzahl von in horizontale Richtung weisenden Strömungsauslässen 38, die in Längsrichtung der Lackierkabine 6 hintereinander angeordnet sind. Jeder Strömungsauslass 38 führt zu einem jeweiligen Filtermodul 40, in welches die Kabinenluft in horizontaler Richtung einströmt. Jedes Filtermodul 40 bildet eine Abscheideeinheit, mit welcher eine insgesamt mit 42 bezeichnete Abscheidevorrichtung arbeitet, die in einem Abscheidebereich 44 der Lackierkabine 6 vorhanden ist, der unterhalb des Strömungsbereichs 30 angeordnet ist.The air duct 36 then diverts the cabin air by 90 ° into the horizontal and comprises a plurality of horizontal outlet flow outlets 38, which are arranged one behind the other in the longitudinal direction of the paint booth 6. Each flow outlet 38 leads to a respective filter module 40, in which the cabin air flows in the horizontal direction. Each filter module 40 forms a separation unit, with which a deposition device, generally designated 42, operates, which is present in a separation area 44 of the painting booth 6, which is arranged below the flow area 30.

Jedes Filtermodul 40 ist als Einzelmodul lösbar mit dem Luftleitkanal 36 verbunden. Die Kabinenluft wird in jedem Filtermodul 40 noch zweimal um 90° umgelenkt und gelangt nach Durchströmen des Filtermoduls 40 weitgehend von Overspraypartikeln befreit in einen Zwischenkanal 46, über den sie in einen Sammelströmungskanal 48 gelangt.Each filter module 40 is releasably connected as an individual module with the air duct 36. The cabin air is deflected twice in each filter module 40 by 90 ° and, after flowing through the filter module 40 largely freed from overspray particles in an intermediate channel 46, via which it passes into a collecting flow channel 48.

Die Kabinenluft wird über den Sammelströmungskanal 48 einer weiteren Aufbereitung und Konditionierung zugeführt und im Anschluss daran in einem hier nicht eigens gezeigten Kreislauf wieder in den Luftzuführraum 14 geleitet, aus dem sie wieder von oben in den Lackiertunnel 8 einströmt.The cabin air is supplied via the collecting flow channel 48 to a further conditioning and conditioning and then passed in a not shown here circuit back into the air supply chamber 14, from which it flows back into the paint tunnel 8 from above.

Anstelle der mit Durchströmungsfiltern arbeitenden Abscheidevorrichtung 42 kann auch eine an und für sich bekannte elektrostatisch arbeitende Abscheidevorrichtung vorgesehen sein, bei welcher die Lackpartikel durch Sprühelektroden ionisiert und an Abscheideflächen abgeschieden werden, die hierzu mit einer Hochspannungsquelle verbunden sind.Instead of the separating device 42 which operates with flow-through filters, it is also possible to provide an electrostatically functioning separating device which is known per se, in which the paint particles are ionized by spray electrodes and deposited on separation surfaces which For this purpose are connected to a high voltage source.

Wie oben angesprochen, kann mittels der Strömungseinrichtung 16 das Strömungsprofil des Kabinenluftstroms beeinflusst werden. Diese Beeinflussung kann einerseits bedeuten, dass ein inhomogenes Strömungsprofil, bei dem die Kabinenluft in verschiedenen Bereichen der Lackierkabine 6 mit unterschiedlichen Strömungsgeschwindigkeiten strömt, derart homogenisiert wird, dass die Kabinenluft in allen Bereichen der Lackierkabine 6 mit weitgehend gleicher Strömungsgeschwindigkeit durch den Lackiertunnel 8 hindurch strömt. Bei einem vertikalen Strömungsweg der Kabinenluft ist das Strömungsprofil der Kabinenluft dann durch lokal gleiche Luftsinkgeschwindigkeiten charakterisiert.As mentioned above, by means of the flow device 16, the flow profile of the cabin air flow can be influenced. On the one hand, this influence can mean that an inhomogeneous flow profile, in which the cabin air flows in different regions of the spray booth 6 at different flow velocities, is homogenized such that the cabin air flows through the paint tunnel 8 in all areas of the spray booth 6 at substantially the same flow rate. In a vertical flow path of the cabin air, the airfoil of the cabin air is then characterized by locally equal air sinking speeds.

Andererseits kann ein in diesem Sinne homogenes Strömungsprofil derart beeinflusst werden, dass die Kabinenluft mit lokal unterschiedlichen Strömungsgeschwindigkeiten durch den Lackiertunnel 8 hindurch strömt. Bei einem vertikalen Strömungsweg der Kabinenluft ist das Strömungsprofil der Kabinenluft somit durch lokal unterschiedliche Luftsinkgeschwindigkeiten charakterisiert.On the other hand, a flow profile that is homogeneous in this sense can be influenced in such a way that the cabin air flows through the painting tunnel 8 at locally different flow velocities. In a vertical flow path of the cabin air, the airfoil of the cabin air is thus characterized by locally different air sink rates.

Hierzu umfasst die Strömungseinrichtung 16 eine Vielzahl von Strömungseinheiten 50. Diese sind beim in den Figuren 1 und 2 gezeigten Ausführungsbeispiel als Ventilatoren 52 ausgebildet, welche Luft aus dem Luftzuführraum 14 in den Lackiertunnel 8 fördern. In den Figuren 1 bis 3 tragen nur einige der Ventilatoren 52 ein Bezugszeichen.For this purpose, the flow device 16 comprises a plurality of flow units 50. These are when in the FIGS. 1 and 2 shown embodiment, designed as fans 52 which promote air from the air supply chamber 14 in the paint tunnel 8. In the FIGS. 1 to 3 only some of the fans 52 carry a reference numeral.

Die Ventilatoren 52 sind in einer Strömungsmatrix 54 angeordnet, welche sich in Längs- und Querrichtung der Lackierkabine 6 erstreckt und die Kabinendecke 12 abdeckt. Jeder Ventilator erzeugt einen eigenen Einzelstrom 56, wie es in Figur 3 veranschaulicht ist. Dabei kann jeder Ventilator 52 separat angesteuert werden, so dass jeder Ventilator 52 einen eigenen Einzelstrom 56 mit einer vorgegebenen Strömungsgeschwindigkeit erzeugen kann, wie es in Figur 3 anhand unterschiedlicher langer Strömungsbilder veranschaulicht ist. Auf diese Weise kann ein Strömungsprofil 58 ausgebildet werden, wobei lediglich in Figur 3 ein Beispiel eines möglichen Strömungsprofils mit einem Bezugszeichen versehen ist. Die Anzahl der erzeugbaren Einzelströme 56 bzw. der Einzelströme, deren Strömungsgeschwindigkeit beeinflusst werden kann, und die Strömungsfläche, welche von diesen jeweils abgedeckt wird, hängen von der Anzahl, der Anordnung und der Dimensionierung der Ventilatoren 52 in der Kabinendecke 12 ab.The fans 52 are arranged in a flow matrix 54, which extends in the longitudinal and transverse direction of the painting booth 6 and covers the cabin ceiling 12. Each fan generates its own individual stream 56, as it is in FIG. 3 is illustrated. In this case, each fan 52 be controlled separately, so that each fan 52 can generate its own individual stream 56 at a predetermined flow rate, as in FIG. 3 illustrated by different long flow images. In this way, a flow profile 58 can be formed, wherein only in FIG. 3 an example of a possible flow profile is provided with a reference numeral. The number of individual streams 56 that can be generated, or the individual streams whose flow velocity can be influenced, and the flow area which they cover in each case depend on the number, arrangement and dimensioning of the fans 52 in the cabin ceiling 12.

Jeder E.inzelstrom 56 hat einen mittleren Strömungsquerschnitt. Während beim vorliegenden Ausführungsbeispiel alle Ventilatoren 52 gleich dimensioniert sind, können abweichend davon auch unterschiedliche große Ventilatoren 52 vorhanden sein, so dass verschieden Einzelströme 56 auch unterschiedliche mittlere Strömungsquerschnitte haben können.Each individual single-ended flow 56 has a medium flow cross-section. While all fans 52 are dimensioned the same in the present embodiment, different sized fans 52 may be present, so that different individual flows 56 may also have different average flow cross sections.

Damit das Strömungsprofil 58 erfasst und an örtliche Gegebenheiten und Anforderungen angepasst werden kann, ist eine Strömungssensoreinrichtung 60 vorhanden, welche in Figur 3 der Übersichtlichkeit halber nicht gezeigt ist. Diese umfasst eine Vielzahl von Strömungssensoren 62, welche die jeweilige Strömungsgeschwindigkeit eines der Einzelströme 56 erfassen können. Hierzu ist in dem Lackiertunnel 8 unterhalb von jeder Strömungseinheit 50, beim Ausführungsbeispiel nach den Figuren 1 und 2 also unterhalb von jedem Ventilator 52, ein Strömungssensor 62 angeordnet. Die Strömungssensoren 62 sind somit in einer Sensormatrix 64 angeordnet, welche der durch die Ventilatoren 52 ausgebildeten Strömungsmatrix 54 entspricht. Die Strömungssensoren 62 sind dabei von einer Haltestruktur 66 getragen, die beim vorliegenden Ausführungsbeispiel als für die Kabinenluft durchlässiges Gitter ausgebildet ist, an dessen Gitterkreuzungen jeweils ein Strömungssensor 62 angebracht ist. Es können auch weniger oder mehr Strömungssensoren 62 eingesetzt werden als Strömungseinheiten 50 vorhanden sind.So that the flow profile 58 can be detected and adapted to local conditions and requirements, a flow sensor device 60 is present, which in FIG. 3 for the sake of clarity is not shown. This includes a plurality of flow sensors 62, which can detect the respective flow velocity of one of the individual streams 56. For this purpose, in the paint tunnel 8 below each flow unit 50, in the embodiment of the FIGS. 1 and 2 that is, below each fan 52, a flow sensor 62 is arranged. The flow sensors 62 are thus arranged in a sensor matrix 64 which corresponds to the flow matrix 54 formed by the fans 52. The flow sensors 62 are supported by a support structure 66, which in the present embodiment as a permeable for the cabin air grid is formed, at whose grid intersections in each case a flow sensor 62 is attached. Also, fewer or more flow sensors 62 may be employed than flow units 50 are present.

Unter Berücksichtigung der von den Strömungssensoren 62 erhaltenen Ausgangssignale kann von einer hier nicht eigens gezeigten Steuereinheit das erhaltene Strömungsprofil 58 über die gesamte Fläche der Lackierkabine 6 überwacht und eingestellt werden. Wenn die Ist-Strömungsgeschwindigkeit eines Einzelstroms 56, der durch einen bestimmten Ventilator 52 erzeugt wird, von einer Soll-Strömungsgeschwindigkeit dieses Einzelstroms 56 abweicht, wird der zugehörige Ventilator 52 entsprechend angesteuert, bis der erzeugte Einzelstrom 56 den Profilvorgaben entspricht.Taking into account the output signals obtained from the flow sensors 62, the resulting flow profile 58 can be monitored and adjusted over the entire surface of the spray booth 6 by a control unit not specifically shown here. If the actual flow rate of a single stream 56, which is generated by a specific fan 52, deviates from a desired flow rate of this single stream 56, the associated fan 52 is driven accordingly until the generated individual stream 56 corresponds to the profile specifications.

Bei einer nicht eigens gezeigten Abwandlung kann die Sensoreinrichtung 60 auch ein Bilderfassungssystem umfassen, mit dessen Hilfe die im Lackiertunnel 8 vorliegende Lackwolke erfasst und im Hinblick auf lokale Strömungsgeschwindigkeiten der Kabinenluft ausgewertet werden kann. Gegebenenfalls kann auch eine Sprüheinrichtung vorhanden sein, mit welcher ein Prüfnebel in dem Lackiertunnel 8 erzeugt werden kann, um ein Prüfbild zu erzeugen, dass von dem Bilderfassungssystem ausgewertet werden kann.In a modification not specifically shown, the sensor device 60 may also comprise an image acquisition system, with the help of which the paint cloud present in the paint tunnel 8 can be detected and evaluated with regard to local flow velocities of the cabin air. Optionally, there may also be a spraying device with which a test mist can be generated in the painting tunnel 8 in order to generate a test pattern that can be evaluated by the image acquisition system.

Bei einer weiteren Abwandlung kann die Sensoreinrichtung 60 auch über eine partielle Druckmessung arbeiten. In diesem Fall können z.B. die Drücke vor und hinter den Strömungseinheiten 50 gemessen werden, woraus dann ein Strömungsprofil abgeleitet werden kann.In a further modification, the sensor device 60 can also operate via a partial pressure measurement. In this case, e.g. the pressures are measured before and after the flow units 50, from which then a flow profile can be derived.

In Figur 2 ist als ergänzende Abwandlung noch einer der Applikationsroboter 24 mit einem weiteren Strömungssensor 68 ausgestattet, welcher nahe am Abgabeende des Roboterarms angebracht ist. Mit Hilfe dieses Strömungssensors 68 kann die Strömungsgeschwindigkeit der Kabinenluft am Ort der Applikation erfasst und mit den Sollvorgaben verglichen werden. Bei Abweichungen können entsprechend Ventilatoren 52 anders angesteuert werden, um das Strömungsprofil 58 zu optimieren.In FIG. 2 As a supplementary modification, one of the application robots 24 is also equipped with a further flow sensor 68 which is mounted close to the delivery end of the robot arm is. With the help of this flow sensor 68, the flow velocity of the cabin air can be detected at the place of application and compared with the target specifications. In the event of deviations, ventilators 52 can be actuated differently in order to optimize the flow profile 58.

Das in Figur 3 gezeigte Strömungsprofil 58 spiegelt beispielhaft eine erste mögliche Anwendungsvariante der Strömungseinrichtung 16 wider: In Figur 3 bezeichnet 70 einen mittleren Hauptbereich des Lackiertunnels 8, der sich in dessen Längsrichtung erstreckt und in welchem die Fahrzeugkarosserien 4 durch den Lackiertunnel 8 gefördert werden. Der Hauptbereich 70 ist rechts und links von Nebenbereichen 72 flankiert, in welchem sich die Applikationsroboter 24 befinden. Üblicherweise fällt in solchen Nebenbereichen 72 die größte Menge an Overspray an.This in FIG. 3 shown flow profile 58 exemplifies a first possible application variant of the flow device 16: In FIG. 3 70 denotes a central main portion of the painting tunnel 8 which extends in the longitudinal direction thereof and in which the vehicle bodies 4 are conveyed through the painting tunnel 8. The main area 70 is flanked on the right and left by secondary areas 72 in which the application robots 24 are located. Usually, the highest amount of overspray occurs in such subregions 72.

Dementsprechend kann ein in diesem Fall zielführendes Strömungsprofil 58 so ausgebildet sein, dass die Einzelströme 56, welche die Nebenbereiche 72 des Lackiertunnels 8 durchströmen, mit höherer Strömungsgeschwindigkeit erzeugt werden als die Einzelströme 56, welche den Hauptbereich 70 des Lackiertunnels 8 durchströmen. Dies ist - wie erwähnt - in Figur 3 veranschaulicht. Dieses Strömungsprofil 58 kann z.B. feiner eingestellt werden, indem in Bereichen von vertikalen Seitenwänden oder Seitenbereichen der Fahrzeugkarosserie 4 die Strömungsgeschwindigkeiten der dort auftreffenden Einzelströme 56 höher sind, über der Fahrzeugkarosserie 4 die Strömungsgeschwindigkeit der Kabinenluft demgegenüber jedoch gedrosselt wird.Accordingly, a flow profile 58 which is effective in this case can be designed so that the individual streams 56 which flow through the secondary regions 72 of the coating tunnel 8 are produced at a higher flow rate than the individual streams 56 which flow through the main region 70 of the coating tunnel 8. This is - as mentioned - in FIG. 3 illustrated. This flow profile 58 can, for example, be set finer by the flow velocities of the individual streams 56 impinging there being higher in regions of vertical side walls or side regions of the vehicle body 4, but above the vehicle body 4 throttling the flow velocity of the cabin air.

Darüber hinaus kann das Strömungsprofil 58 in Längsrichtung des Lackiertunnels 8 dynamisch geändert und angepasst werden, während die Fahrzeugkarosserien 4 durch den Lackiertunnel gefördert und dabei beschichtet werden. Insbesondere kann ein Profilmuster des Strömungsprofils 58 dabei mit einer sich bewegenden Fahrzeugkarosserie 14 mitgeführt werden, so dass diese auch beim Durchlauf durch den Lackiertunnel 8 weitgehend immer von demselben Strömungsprofil 58 eingehüllt ist. So können beispielsweise auch die in Längsrichtung des Lackiertunnels 8 weisenden vertikalen Stirnwände oder Stirnbereiche Fahrzeugkarosserien 4 berücksichtigt werden, indem die Strömungsgeschwindigkeit von jeweils dort auftreffenden Einzelströmen 56 gegenüber anderen Einzelströmen 56 erhöht werden. Einzelströme 56 können dann in Längsrichtung des Lackiertunnels 8 mit der Fahrzeugkarosserie 4 mitwandern. Hierzu wird die Leistung von Ventilatoren 52 erhöht, wenn die Stirnseite einer Fahrzeugkarosserie 4 in den Einzelstrom 56 dieses Ventilators 52 gelang, und wird die Leistung von Ventilatoren 52 wieder gedrosselt, wenn die Stirnseite einer Fahrzeugkarosserie 4 wieder aus dem Einzelstrom 56 dieses Ventilators 52 herausbewegt ist.In addition, the flow profile 58 can be dynamically changed and adjusted in the longitudinal direction of the painting tunnel 8, while the vehicle bodies 4 are conveyed through the painting tunnel and thereby coated. Especially For example, a profile pattern of the airfoil 58 may be carried along with a moving vehicle body 14 so that it is largely always enveloped by the same airfoil 58 as it passes through the paint tunnel 8. For example, the vertical end walls or front areas of vehicle bodies 4 pointing in the longitudinal direction of the painting tunnel 8 can also be taken into account by increasing the flow velocity of individual streams 56 impinging there in relation to other individual streams 56. Individual streams 56 can then migrate in the longitudinal direction of the painting tunnel 8 with the vehicle body 4. For this purpose, the power of fans 52 is increased when the front side of a vehicle body 4 in the single stream 56 of this fan 52 succeeded, and the power of fans 52 is throttled again when the end face of a vehicle body 4 is moved out of the single stream 56 of this fan 52 again ,

In Figur 4 ist als zweites Ausführungsbeispiel eine Lackieranlage 2' gezeigt, bei welcher oben bereits beschriebene Komponenten dieselben Bezugszeichen tragen. Die Strömungssensoreinrichtung 60 ist auch dort der Übersichtlichkeit halber nicht gezeigt.In FIG. 4 is shown as a second embodiment, a paint shop 2 ', in which components already described above bear the same reference numerals. The flow sensor device 60 is also not shown there for the sake of clarity.

Anstelle der Ventilatoren 52 sind die Strömungseinheiten 50 bei diesem Ausführungsbeispiel als Strömungsklappen 74 ausgebildet, die in der Strömungsmatrix 54 angeordnet sind und über welche die Strömungsgeschwindigkeiten der Einzelströme 56 abhängig von dem von den Strömungsklappen 74 freigegebenen Durchgangsquerschnitt eingestellt werden kann. Von den Strömungsklappen 74 sind nur einige mit einem Bezugszeichen versehen.Instead of the fans 52, the flow units 50 are formed in this embodiment as flow flaps 74, which are arranged in the flow matrix 54 and over which the flow rates of the individual streams 56 can be adjusted depending on the released by the flow flaps 74 passage cross section. Of the flow flaps 74 only a few are provided with a reference numeral.

Die jeweilige Stellung der Strömungsklappen 74 kann beispielsweise von Hand eingestellt werden. Alternativ kann dies auch motorisch erfolgen, wozu jede Steuerklappe 74 oder Gruppen aus jeweils mehreren Strömungsklappen 74 jeweils mit einem entsprechenden Aktuator gekoppelt ist bzw. sind. Alternativ kann zur Einstellung der Strömungsklappen 74 auch ein Roboter in dem Lackiertunnel 8 vorgesehen sein; diese Aufgabe kann auch von einem oder von beiden der Applikationsroboter 24 wahrgenommen werden, welche hierzu mit einem entsprechenden Werkzeug ausgestattet sind.The respective position of the flow flaps 74 can be adjusted for example by hand. Alternatively, you can this can also be done by motor, for which purpose each control flap 74 or groups of a plurality of flow flaps 74 is respectively coupled to a corresponding actuator or are. Alternatively, a robot can be provided in the paint tunnel 8 for adjusting the flow flaps 74; This task can also be performed by one or both of the application robot 24, which are equipped for this purpose with a corresponding tool.

Auch hier lassen sich Einzelströme 56 mit unterschiedlichen Strömungsquerschnitten erzeugen. Hierzu sind voneinander verschiedene Strömungsklappen 74 vorhanden, die sich in ihrer Erstreckung quer zur und/oder in Längsrichtung der Lackierkabine 8 unterscheiden.Here, too, individual streams 56 with different flow cross sections can be produced. For this purpose, different flow flaps 74 are present, which differ in their extent transversely to and / or in the longitudinal direction of the paint booth 8.

Bei den oben beschriebenen Ausführungsbeispielen ist die Strömungseinrichtung 16 im Bereich der Kabinendecke 12 angeordnet. Allgemein ausgedrückt sind die Ventilatoren 52 so angeordnet, dass Kabinenluft über die Ventilatoren 52 in die Lackierkabine 6 eingeblasen wird. Hierzu können die Ventilatoren auch unterhalb der Kabinendecke 12 angeordnet sein, die dann beispielsweise als Filterdecke ausgebildet sein kann. Im Falle der Strömungsklappen 74 sind diese, wieder allgemein ausgedrückt, so angeordnet, dass Kabinenluft über die Strömungsklappen in die Lackierkabine 6 eintritt.In the embodiments described above, the flow device 16 is arranged in the region of the cabin ceiling 12. Generally speaking, the fans 52 are arranged so that cabin air is blown into the painting booth 6 via the fans 52. For this purpose, the fans may also be arranged below the cabin ceiling 12, which may then be formed, for example, as a filter cover. In the case of the flow flaps 74, these are, again in general terms, arranged so that cabin air enters the paint booth 6 via the flow flaps.

Bei weiteren nicht eigens gezeigten Abwandlungen kann die jeweilige Strömungseinrichtung 16 jedoch an anderer Stelle vorgesehen sein. So kann die Strömungseinrichtung beispielsweise auch im Bereich der unteren Öffnung 18 des Lackiertunnels 8 angeordnet sein.In other not specifically shown modifications, the respective flow device 16 may be provided elsewhere. For example, the flow device can also be arranged in the region of the lower opening 18 of the painting tunnel 8.

Im Falle der Ventilatoren 52 sind diese dann allgemein ausgedrückt so angeordnet, dass sie Kabinenluft aus der Lackierkabine 6 absaugen. Die Kabinenluft, die aus dem Luftzuführraum 14 in den Lackiertunnel 18 eingetreten ist, wird dabei mit unterschiedlicher Saugstärke aus dem Lackiertunnel 8 nach unten angesaugt, wodurch das gewünschte Strömungsprofil ausgebildet wird.In the case of the fans 52, these are then generally arranged so that they suck cabin air from the spray booth 6. The cabin air coming out of the air supply room 14 has entered the painting tunnel 18 is sucked with different suction power from the painting tunnel 8 down, creating the desired flow profile is formed.

Die Strömungsklappen 74 sind dann so angeordnet ist, dass Kabinenluft über die Strömungsklappen 74 aus der Behandlungskabine austritt. Die Strömungsklappen 74 wirken in diesem Fall als eine Art Bremsklappen, welche das Abströmen der mit Overspray beladenen Kabinenluft nach unten mit unterschiedlicher Stärke Drosseln.The flow flaps 74 are then arranged so that cabin air exits the treatment booth via the flow flaps 74. The flow flaps 74 act in this case as a kind of air flaps, which restrict the outflow of the overspray laden cabin air down with different thickness.

Es kann auch ein Teil der Strömungseinheiten 50 im Bereich der Kabinendecke 12 und der andere Teil der Strömungseinheiten 50 an anderer Stelle vorgesehen sein. Dabei können strömungstechnisch betrachtet benachbarte Strömungseinheiten 50 abwechselnd im Bereich der Kabinendecke 12 und an anderer Stelle angeordnet sind.It is also possible to provide some of the flow units 50 in the area of the cabin ceiling 12 and the other part of the flow units 50 elsewhere. In terms of flow, adjacent flow units 50 can be arranged alternately in the area of the cabin ceiling 12 and elsewhere.

Auch kann die Strömungseinrichtung 16 in Strömungsrichtung hinter der Abscheidevorrichtung 42 angeordnet sein; dies ist ebenfalls bei einer elektrostatisch arbeitenden Abscheidevorrichtung möglich, wie sie weiter oben angesprochen ist.Also, the flow device 16 may be arranged in the flow direction behind the separation device 42; This is also possible with an electrostatically operating separation device, as mentioned above.

Bei einer weiteren Abwandlung kann auch ein Teil der Strömungseinheiten 50 der Strömungseinrichtung 16 durch Ventilatoren 52 und der andere Teil durch Strömungsklappen 74 gebildet sein.In a further modification, a part of the flow units 50 of the flow device 16 may be formed by fans 52 and the other part by flow flaps 74.

Darüber hinaus können Ventilatoren 52 und/oder Strömungsklappen 74 auch in oder an den Seitenwänden 10 der Lackierkabine 6 angeordnet sein, wobei dann Lufträume seitlich neben dem Lackiertunnel 8 vorhanden sind, über welche die Kabinenluft zum Lackiertunnel 8 gefördert wird. In diesem Fall tritt die Kabinenluft beispielsweise schräg nach unten in den Lackiertunnel 8 ein.In addition, fans 52 and / or flow flaps 74 can also be arranged in or on the side walls 10 of the spray booth 6, air spaces then being provided laterally next to the paint tunnel 8, via which the cabin air is conveyed to the paint tunnel 8. In this case, the cabin air enters, for example, obliquely down in the paint tunnel 8 a.
