Description

Die Erfindung betrifft eine Vorrichtung zum Entfernen von Farbnebel aus einem Abluftstrom, insbesondere von Farboverspraynebel in einer Lackierkabine, wobei zumindest einer Wandung des Raums wenigstens abschnittsweise ein Trum wenigstens eines bewegbaren Flächenbandes zugeordnet ist und dem Trum wenigstens eine Farbreinigungseinrichtung zugeordnet ist.The invention relates to a device for removing paint mist from an exhaust air stream, in particular Farboverspraynebel in a paint booth, wherein at least one wall of the room at least partially a strand is associated with at least one movable surface band and the strand at least one color cleaning device is assigned.

Auf voneinander verschiedene technische Gegenstände werden Farben oder andere Mittel mittels Sprayeinrichtungen aufgetragen. Beispielsweise auf Kraftfahrzeugkarosserien werden Grundiermittel, Grundlacke und Decklacke in Lackierkabinen mittels Sprayeinrichtungen aufgetragen. Dabei treffen nicht sämtliche Farbpartikel auf die Gegenstände auf, ein Teil der Farbpartikel bleibt als Farboverspraynebel in dem Abluftstrom. Der Farboverspraynebel ist aus der Kabine abzuführen. Dazu sind im Stand der Technik Nassabscheideverfahren bzw. Nasswaschverfahren vorgeschlagen worden, mit denen der Abluftstrom der Lackierkabine gereinigt wird. Diese Verfahren sind aufwendig und hinsichtlich einzuhaltender Umweltstandards bedenklich.On different technical items colors or other means are applied by means of spray devices. For example, on motor vehicle bodies, primers, base coats and topcoats are applied in spray booths by means of spray devices. Not all the color particles hit the objects, a part of the color particles remains in the exhaust air stream as a color overspray mist. The color overspray mist should be removed from the booth. For this purpose, wet scrubbing methods or wet scrubbing methods have been proposed in the prior art with which the exhaust air flow of the paint booth is cleaned. These methods are complex and questionable in terms of environmental standards to be respected.

Bei bekannten Vorrichtungen zum Entfernen von Farbnebeln unter Einsatz trockener Umgebungsbedingungen sind in die Lackierkabine eingestellte Bauteile bekannt, die nach einer ausreichenden Belegung mit niedergeschlagenem Farbnebel aus der Lackierkabine herausgenommen werden und anschließend gereinigt werden. Auch derartige Austauschverfahren sind aufwendig. Die US 4152008 A zeigt in die Lackierkabine einbringbare Matten.In known devices for removing paint mist using dry ambient conditions set in the paint booth components are known, which are taken out after a sufficient occupancy with knocked paint mist from the spray booth and then cleaned. Such exchange methods are complicated. The US 4152008 A shows in the spray booth insertable mats.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung der eingangs genannten Gattung aufzuzeigen, mit der in konstruktiv einfacher und trockener Verfahrensweise ein zuverlässiger Abtransport von Farbnebel aus einem Raum ermöglicht ist.The invention has for its object to provide a device of the type mentioned, with the structurally simple and Dry procedure allows a reliable removal of paint mist from a room.

Diese Aufgabe ist erfindungsgemäß dadurch gelöst, dass das Trum aus miteinander verbundenen Gliedern in einer ersten Lage und aus miteinander verbundenen Gliedern in einer zweiten Lage ausgebildet ist, wobei jedes glied jeder Lage einen unförmigen Querschnitt hat und die Glieder beider Lagen mit den U-Schenkeln ineinandergreifen.This object is inventively achieved in that the strand is formed of interconnected links in a first layer and interconnected links in a second layer, each member of each layer has a unge-shaped cross section and engage the members of both layers with the U-legs ,

Die erfindungsgemäße Vorrichtung ermöglicht eine Trockenreinigung ohne Waschprozesse. Für den Farbnebel wird ein Objekt zur Verfügung gestellt, auf dem er sich niederschlagen kann. Für dieses Objekt wird das Trum eines bewegbaren Flächenbandes vorgesehen. Auf das Trum kann sich Farbnebel absetzten, mit dem bewegbaren Flächenband wird der abgesetzte Farbnebel dann aus der Lackierkabine herausbewegt.The device according to the invention allows a dry cleaning without washing processes. For the paint mist, an object is made available, on which it can precipitate. For this object, the run of a movable surface band is provided. On the strand color mist can settle, with the movable surface band of the remote color mist is then moved out of the spray booth.

Das Bereithalten von Abschnitten eines Trums zum Absetzen des Farbnebels und das Herausführen des abgesetzten Farbnebels aus der Lackierkabine ist automatisierbar. Der Prozess kann kontinuierlich erfolgen, die Geschwindigkeit des bewegbaren Flächenbandes kann beispielsweise etwa 3 mm bis 2 m pro Minute betragen.It is possible to automate the provision of sections of a run for discontinuing the paint mist and removing the settled paint mist from the paint booth. The process can be continuous, for example, the speed of the movable surface band may be about 3 mm to 2 meters per minute.

Der abgesetzte Farbnebel wird mit dem Trum einer Farbreinigungseinrichtung zugeführt. Die Farbreinigungseinrichtung ist dem Trum zugeordnet, das an einem Ort außerhalb der Lackierkabine. Mit dem Trum können während des Abführens mit Farbnebel besetzter Abschnitte neue noch ohne Farbnebelabsätze versehene Abschnitte des Trums in die Lackierkabine eingeführt werden.The settled color mist is supplied with the strand of a color cleaner. The color cleaning device is associated with the strand, which at a location outside of the paint booth. With the strand can be introduced during the discharge with color fog occupied sections new still provided without Farbnebelabsätze sections of the strand in the spray booth.

Die Erfindung sieht vor, dass das Trum aus miteinander verbundenen Gliedern in einer ersten Lage und aus miteinander verbundenen Gliedern in einer zweiten Lage ausgebildet ist. Die Ausbildung als Glieder führt zu einer Kettenbauform. Dem Farbnebel werden zwei Lagen von Gliedern dargeboten, durch die den Farbnebel transportierende Luft hindurchtreten kann. Zwischen den Gliedern jeder Lage ist dazu ein Abstand von etwa 1 cm bis 5 cm ausgebildet. Dieser geringe Abstand behindert nicht die Betretbarkeit des Trums, der Abstand ermöglicht aber einen Durchtritt der den Farbnebel transportierenden Luft.The invention provides that the strand of interconnected links is formed in a first layer and of interconnected links in a second layer. The training as members leads to a Chain design. The paint mist is presented with two layers of limbs through which the paint mist transporting air can pass. Between the members of each layer to a distance of about 1 cm to 5 cm is formed. This small distance does not hinder the accessibility of the strand, the distance but allows passage of the color mist transporting air.

Jedes Glied jeder Lage hat nach der Erfindung einen u-förmigen Querschnitt, die Glieder beider Lagen sind vorzugsweise ineinandergreifend ausgebildet. Dazu können zwischen die U-Schenkel zweier einander benachbarter U-Schenkel der Glieder der anderen Lage eingeführt werden. Die den Farbnebel transportierende Luft tritt durch diese Glieder hindurch und wird an den Kanten der einzelnen U-Profile abgelenkt. Dadurch treten auf die Farbnebelpartikel Fliehkräfte auf, welche ihre Anlage an den Gliedern beider Lagen befördern.Each member of each layer according to the invention has a U-shaped cross-section, the members of both layers are preferably formed interlocking. For this purpose, the members of the other layer can be inserted between the U-legs of two adjacent U-legs. The air transporting the paint mist passes through these members and is deflected at the edges of the individual U-profiles. As a result, centrifugal forces occur on the paint mist particles, which convey their contact with the links of both layers.

Die Glieder der Lagen können beispielsweise eine Baulänge von 4 m haben und somit die Breite einer Lackierkabine weitgehend abdecken. Die Glieder in den Lagen sind dabei über Rollen geführt und in einem Abschnitt dieser Führung mit einem größeren Abstand zueinander versehen. In diesem größeren Abstand werden die beiden Lagen voneinander entfernt. Insbesondere wird der wechselseitige Eingriff der U-Schenkel der Glieder in die Glieder der anderen Lage aufgehoben.The members of the layers, for example, have a length of 4 m and thus cover the width of a paint booth largely. The links in the layers are guided over rollers and provided in a portion of this guide with a greater distance from each other. At this greater distance, the two layers are removed from each other. In particular, the mutual engagement of the U-legs of the links in the links of the other position is canceled.

Das erfindungsgemäß vorgesehene Trum kann dabei beispielsweise in einem Abstand vor einer Wandung des Raums angeordnet sein. Vorzugsweise ist vorgesehen, dass zumindest eine Wandung des Raumes wenigstens abschnittsweise durch das Trum ausgebildet ist. Das Trum ist nach dieser Weiterbildung direkt in die Wand eingelassen, so dass keine zusätzlichen Aufbauten vor der Wand notwendig sind.The strand provided according to the invention can be arranged, for example, at a distance in front of a wall of the room. It is preferably provided that at least one wall of the space is at least partially formed by the strand. The strand is embedded according to this development directly into the wall, so that no additional structures in front of the wall are necessary.

Dabei ist vorzugsweise vorgesehen, dass das Trum des Flächenbandes in den Boden des Raumes eingelassen ist. Farbnebel in der Atmosphäre des Raumes sinkt aufgrund der Schwerkraft und Luftunterstützung nach unten und trifft auf den Boden auf. Wenn dieser Boden durch das Trum des bewegbaren Flächenbandes ausgebildet ist, kann der aufgetroffene Farbnebel mit dem Flächenband wegtransportiert werden. Das Flächenband ist dabei so ausbildbar, dass es von Personen betreten werden kann.It is preferably provided that the strand of the surface band is embedded in the bottom of the room. Color fog in the atmosphere of the room sinks down due to gravity and air support and strikes the floor. If this bottom is formed by the run of the movable surface band, the impacted color mist can be transported away with the surface band. The surface band can be formed in such a way that it can be entered by persons.

Nach einer nächsten Weiterbildung der Erfindung ist die Farbreinigungseinrichtung in diesem Bereich dem Flächenband zugeordnet, in dem die Lagen des Flächenbandes den größeren Abstand zueinander aufweisen. In diesem Bereich sind die beiden Lagen des Flächenbandes voneinander separiert. Dadurch ist es der Farbreinigungseinrichtung ermöglicht, beide Lagen von beiden Seiten gründlich zu reinigen. Für jede Seite jeder Lage ist eine Farbreinigungseinrichtung vorgesehen.According to a next development of the invention, the color cleaning device in this area is assigned to the surface band in which the layers of the surface band have the greater distance from each other. In this area, the two layers of the surface band are separated from each other. This allows the paint-cleaning device to thoroughly clean both layers from both sides. For each side of each layer, a color cleaner is provided.

Nach einer Weiterbildung der Erfindung ist vorgesehen, dass jede Farbreinigungseinrichtung einen Laserkopf umfasst. Mit einem Laserstrahl wird von jeder Seite auf jede Lage des Flächenbandes eingewirkt, auf der Lage befindliche Farbpartikel werden weggebrannt bzw. weggedampft. Zurück bleiben gereinigte Glieder der Lagen den Flächenbandes, die nachfolgend wieder einander angenähert werden können, so dass die Glieder wieder ineinandergreifen.According to a development of the invention, it is provided that each color cleaning device comprises a laser head. A laser beam acts on each layer of the surface band from each side, color particles located on the layer are burnt away or vaporized away. Purified limbs of the layers remain behind the surface band, which can subsequently be brought closer to each other again so that the members interlock again.

Diese gereinigten Abschnitte des Flächenbandes können erneut in die Lackierkabine eingeführt werden, in dem sie beispielsweise erneut den Boden der Lackierkabine abschnittsweise ausbilden. Das Flächenband kann dazu als in sich geschlossene Schlaufe ausgebildet sein, die automatisiert von der Lackierkabine zur Farbreinigungseinrichtung und wieder zurück in die Lackierkabine geführt wird.These cleaned sections of the surface band can be reintroduced into the paint booth, in which, for example, they again form the bottom of the paint booth in sections. The surface band can be designed as a self-contained loop, which is performed automatically from the spray booth to the color cleaning device and back to the paint booth.

Für diese Führung sind dem Flächenband vorzugsweise strangförmige Antriebsmittel zugeordnet, beispielswiese Antriebsketten. Das Flächenband kann wenigstens abschnittsweise in einem Gehäuse angeordnet sein, um seine Bauteile und insbesondere die Laserköpfe gegen äußere Einflüsse zu schützen. Die Bauteile der erfindungsgemäßen Vorrichtung können dann räumlich unterhalb einer Lackierkabine angeordnet werden, so dass keine Einbauten in der Lackierkabine selbst notwendig sind.For this guide, the surface band is preferably associated with strand-shaped drive means, for example drive chains. The surface band can be arranged at least in sections in a housing in order to protect its components and in particular the laser heads against external influences. The components of the device according to the invention can then be arranged spatially below a painting booth, so that no installations in the paint booth itself are necessary.

In Figur 1 ist im Bereich der Pfeile 1 eine Lackierkabine beispielsweise für Kraftfahrzeugkarosserien angedeutet. In der Lackierkabine treten Farbnebel 2 auf. Die erfindungsgemäße Vorrichtung sieht für die Wegnahme dieses Farbnebels 2 aus der Lackierkabine ein bewegbares Flächenband 3 vor. Die Bewegbarkeit des Flächenbandes ist mit Pfeilen 4 dargestellt. Das Flächenband 3 besteht aus zwei einander zugeordneten Lagen 5. Im Bereich der Lackierkabine sind die Lagen 5 einander angenähert, sie bilden für den Farbnebel 2 eine zweilagige Anlagemöglichkeit dar. Die Anlage von Farbe an beiden Lagen 5 ist durch eine Beschichtung 6 jeweils angedeutet.In FIG. 1 in the area of the arrows 1 a painting booth, for example for motor vehicle bodies, is indicated. In the paint booth paint mist 2 occur. The device according to the invention provides for the removal of this paint mist 2 from the paint booth before a movable surface belt 3. The mobility of the surface band is shown by arrows 4. The surface band 3 consists of two mutually associated layers 5. In the paint booth, the layers 5 are approximated to each other, they form a two-layer investment opportunity for the paint mist 2. The plant of color on both layers 5 is indicated by a coating 6 respectively.

Die beschichteten Abschnitte des Flächenbandes 3 werden aus einem der Lackierkabine zugeordneten Trum über Rollenketten 7 in andere Trums überführt. In einem vertikalen Trum sind beide Lagen 5 zueinander mit einem größeren Abstand versehen. Hier sind als Laserköpfe 8 ausgebildete Farbreinigungseinrichtungen angeordnet. Mit den Laserköpfen 8 wird die auf den Lagen 5 befindliche Farbe von den Lagen 5 entfernt. Dazu können die Laserköpfe 8 entlang der Doppelpfeile 9 bewegt werden, um bei der gegebenen Bewegung des Flächenbandes 3 eine vollständige Reinigung desselben zu erreichen. Nachfolgend wird das Flächenband 3 in einem unteren Trum über weitere Rollenketten 7 geführt, und es werden beide Lagen 5 einander wieder angenähert. Das Flächenband 3 wird schließlich der Lackierkabine erneut zugeführt, so dass es wieder Farbnebel 2 aufnehmen kann. Das Flächenband 3 liegt somit als geschlossene Schlaufe vor, der in Figur 1 dargestellte Betrieb der Vorrichtung kann automatisiert werden.The coated sections of the surface band 3 are from one of the paint booth associated Trum roller chains 7 in other runs transferred. In a vertical run both layers 5 are provided to each other with a greater distance. Here are designed as laser heads 8 trained color cleaning facilities. With the laser heads 8 located on the layers 5 color is removed from the layers 5. For this purpose, the laser heads 8 can be moved along the double arrows 9 in order to achieve the same movement of the surface belt 3 a complete cleaning. Subsequently, the surface band 3 is guided in a lower run on more roller chains 7, and it will be both layers 5 approached each other again. The surface strip 3 is finally fed back to the paint booth, so that it can absorb paint mist 2 again. The surface band 3 is thus present as a closed loop, the in FIG. 1 illustrated operation of the device can be automated.

Figur 2 zeigt, dass beiden Lagen 5 kettenförmige Antriebsmittel 10 zugeordnet sind. Die Antriebsmittel 10 tragen Glieder 11 jeder Lage 5 und sind über die Rollen 7 geführt. FIG. 2 shows that 5 chain-shaped drive means 10 are assigned to both layers. The drive means 10 carry members 11 each layer 5 and are guided over the rollers 7.

Figur 3 zeigt noch, dass die erfindungsgemäße Vorrichtung ein Gehäuse 12 aufweist. Die Glieder 11 jeder Lage 5 haben jeweils einen u-förmigen Querschnitt. Im Bereich der Lackierkabine sind die Glieder 11 ineinander geführt, indem die U-Schenkel eines Gliedes 11 die einander zugeordneten U-Schenkel einander benachbarter Glieder 11 der anderen Lage 5 übergreifen. Figur 3 zeigt, wie im Bereich der Rollen 7 ein Aus- und Eingriff der Glieder 11 erfolgt. FIG. 3 shows that the device according to the invention has a housing 12. The members 11 of each layer 5 each have a U-shaped cross-section. In the area of the paint booth, the links 11 are guided one inside the other by the U-legs of one link 11 overlapping the associated U-legs of adjacent links 11 of the other layer 5. FIG. 3 shows how in the area of the rollers 7 a disengagement and engagement of the members 11 takes place.

Mit den ineinander geführten Gliedern 11 wird den Farbnebel 2 transportierender Luft ein Weg bereitet, der zu Ablenkungen der Luftführung führt. In der Luft enthaltene Farbpartikel können sich auf den Gliedern 11 absetzen. Die Glieder 11 werden in beiden Lagen 5 des Flächenbandes 3 anschließend zu den Farbreinigungseinrichtungen mit den Laserköpfen 8 geführt und von der aufgetroffenen Farbe wieder befreit.With the nested members 11, the paint mist 2 transporting air is preparing a path that leads to distractions in the air duct. Color particles contained in the air can settle on the limbs 11. The members 11 are then performed in two layers 5 of the surface strip 3 to the color cleaning facilities with the laser heads 8 and freed from the impacted color again.
