Description

Die Erfindung betrifft eine Einrichtung zum Naßlack-Spritzlackieren von Gegenständen mit einer Vorrichtung zum Auffangen des Lacküberschusses, die einen luftdurchlässigen Trockenfilter aufweist.The invention relates to a device for wet paint spray painting objects with a device for collecting the excess paint, which has an air-permeable dry filter.

Zum Auffangen des Lacküberschusses bei der Naßlack-Spritzlackierung (also beim Spritzlackieren von flüssigen Medien, beispielsweise über Spritzdüsen oder Spritzpistolen) ist es bereits bekannt, den Lacküberschuß durch eine Filterfläche aufzunehmen und dann aus dieser Filterfläche auszuwaschen. Bei einem solchen Naßabscheideverfahren müssen allerdings wenig umweltverträgliche Lösungsmittel eingesetzt werden und außerdem Trocknungseinrichtungen vorgesehen sein, um das Filtermaterial nach dem Auswaschen zu trocknen.In order to collect the excess paint in wet paint spray painting (i.e. when spray painting liquid media, for example using spray nozzles or spray guns), it is already known to absorb the paint excess through a filter surface and then wash it out of this filter surface. In such a wet separation method, however, solvents which are not very environmentally friendly have to be used and, in addition, drying devices have to be provided in order to dry the filter material after washing out.

Neben solchen Naßabscheideverfahren, die beispielsweise aus der DE-OS 36 18 642 und der DE-OS 43 00 400 bekannt sind, ist es bereits auch bekannt, luftdurchlässige Trockenfilter zu verwenden, die, nachdem sie vom Lacküberschuß zugesetzt sind, weggeworfen werden. Dies ist nicht nur unökonomisch, sondern auch aus dem Gesichtspunkt des Umweltschutzes untragbar.In addition to such wet separation processes, which are known, for example, from DE-OS 36 18 642 and DE-OS 43 00 400, it is also known to use air-permeable dry filters which, after they have been added by excess paint, are thrown away. This is not only uneconomical, but also unbearable from the point of view of environmental protection.

Aufgabe der Erfindung ist es, eine umweltverträgliche und im Betrieb kostengünstige Einrichtung zum Naßlack-Spritzlackieren von Gegenständen zu schaffen.The object of the invention is to provide an environmentally compatible and inexpensive device for wet spray painting objects.

Erfindungsgemäß wird dies bei einer Einrichtung der eingangs genannten Gattung dadurch erreicht, daß der Trockenfilter bewegbar angeordnet ist und eine Absaugeinrichtung vorgesehen ist, die die während einer bestimmten Zeit aufgetrockneten Lackpartikel vom Trockenfilter absaugt.According to the invention, this is achieved in a device of the type mentioned at the outset in that the dry filter is arranged to be movable and a suction device is provided, which during a certain period Vacuum dried up paint particles from the dry filter.

Der Erfindung liegt die Erkenntnis zugrunde, daß es nicht nötig ist, beim Naßlack-Spritzlackieren den vom Filter aufgefangenen Lacküberschuß mit flüssigem Lösungsmittel in einem Naßabscheideverfahren auszuwaschen, sondern daß es vielmehr ausreicht, den Lacküberschuß nach einer bestimmten Trocknungsstrecke vom Trockenfilter abzusaugen, sodaß dieser nicht weggeworfen werden muß. Das Absaugen von Filtern ist bei Pulverbeschichtungsanlagen seit langem bekannt. Bei solchen Anlagen wird ein Pulver, beispielsweise elektrostatisch auf die zu beschichtenden Gegenstände aufgebracht und der Pulverüberschuß abgesaugt (z. B. DE 28 13 854 C2). Im Gegensatz dazu betrifft die Erfindung eine andere Gattung, nämlich das Naßlack-Spritzlackieren mit flüssigen Medien. Bei diesem Naßlack-Spritzlackieren haftet der Lacküberschuß im Gegensatz zu bloßem Pulver wesentlich fester an der Filterfläche und man war daher bisher der Meinung, daß man entweder einen Trockenfilter wegwerfen muß bzw. in einem aufwendigen Naßverfahren auswaschen muß. Überraschend haben aber Versuche der Anmelderin gezeigt, daß sich auch beim Naßlack-Spritzlackieren von Gegenständen der Lacküberschuß von einem Trockenfilter ohne aufwendiges Naßabscheideverfahren absaugen läßt.The invention is based on the knowledge that it is not necessary to wash off the excess paint collected by the filter with liquid solvent in a wet separation process during wet paint spray painting, but rather that it is sufficient to suck off the excess paint from the dry filter after a certain drying distance so that it is not thrown away must become. Vacuuming filters has long been known in powder coating systems. In such systems, a powder, for example electrostatically, is applied to the objects to be coated and the excess powder is suctioned off (for example DE 28 13 854 C2). In contrast, the invention relates to another genre, namely wet paint spray painting with liquid media. In this wet paint spray painting, the excess paint adheres to the filter surface much more firmly than mere powder, and it was previously thought that either a dry filter had to be thrown away or washed out in a complex wet process. Surprisingly, however, tests by the applicant have shown that even in the case of wet spray painting of objects, the excess paint can be sucked off from a dry filter without a complex wet separation process.

Dabei ist es besonders günstig, wenn die Absaugeinrichtung an einer Stelle angeordnet ist, die von jenem Bereich entfernt ist, in dem der Trockenfilter den Lacküberschuß aufnimmt, weil dann die Lackpartikel auch bei kontinuierlich bewegtem Trockenfilter ausreichend Zeit haben, ganz zu trocknen und somit leicht absaugbar zu sein.It is particularly expedient if the suction device is arranged at a location which is distant from the area in which the dry filter absorbs the excess paint, because then the paint particles have enough time to dry completely and are therefore easy to extract even when the dry filter is moved continuously to be.

Weitere Vorteile und Einzelheiten der Erfindung werden anhand der nachfolgenden Figurenbeschreibung näher erläutert.Further advantages and details of the invention are explained in more detail with reference to the following description of the figures.

Die Fig. 1 zeigt eine Einrichtung zum Naßlack-Spritzlackieren von Gegenständen 1 mittels einer händisch bedienbaren Spritzpistole 2, welche beispielsweise einen Behälter für flüssigen Lack aufweist und an eine Druckluftleitung 3 angeschlossen ist. Zum Auffangen des Lacküberschusses, der am Gegenstand 1 vorbeitritt, ist erfindungsgemäß ein luftdurchlässiger Trockenfilter 4 vorgesehen, der über Umlenktrommeln 5 bewegbar angeordnet ist. Erfindungsgemäß ist außerdem eine Absaugeinrichtung 6 vorgesehen, deren Einsaugöffnung 7 an einer in Bewegungsrichtung des Trockenfilters 4 möglichst entfernten Stelle vom Bereich 8 liegt, in dem der Trockenfilter Lacküberschuß aufnimmt. Zwischen dem Vordertrum und dem Hintertrum des endlos umlaufenden Trockenfilters ist ein Abluftkanal 9 einer Abluftanlage angeschlossen, die Luft aus dem Abluftkanal 9 absaugt. Die Vorderseite dieses Abluftkanales 9 ist an der Stelle 10 perforiert bzw. luftdurchlässig ausgebildet, damit die durch den Trockenfilter 4 hindurchtretende Abluft in den Abluftkanal 9 eintreten kann. Dabei werden die Lackpartikel vom Trockenfilter 4 aufgefangen und später von der Absaugeinrichtung 6 abgesaugt. Damit ist es möglich, den Trockenfilter 4 laufend zu reinigen. Der Trockenfilter kann kontinuierlich bewegt werden. Es ist aber auch ein diskontinuierliches Bewegen möglich, beispielsweise in einem gesonderten Reinigungslauf am Abend.1 shows a device for the wet paint spray painting of objects 1 by means of a manually operated spray gun 2, which for example has a container for liquid paint and is connected to a compressed air line 3. An air-permeable dry filter 4 is provided according to the invention to catch the excess paint that passes past the object 1 and is arranged so as to be movable over deflection drums 5. According to the invention, a suction device 6 is also provided, the suction opening 7 of which lies at a point as far away as possible from the area 8 in the direction of movement of the dry filter 4, in which the Dry filter absorbs excess paint. An exhaust air duct 9 of an exhaust air system is connected between the front run and the rear run of the endlessly circulating dry filter, which sucks air out of the exhaust air duct 9. The front of this exhaust air duct 9 is perforated or air-permeable at the point 10 so that the exhaust air passing through the dry filter 4 can enter the exhaust air duct 9. The paint particles are collected by the dry filter 4 and later sucked off by the suction device 6. This makes it possible to continuously clean the dry filter 4. The dry filter can be moved continuously. However, discontinuous movement is also possible, for example in a separate cleaning run in the evening.

Der Trockenfilter 4 wird vorteilhaft zweiteilig ausgebildet, nämlich aus einem luftdurchlässigen, statisch stabilen aber dennoch flexiblen Träger 4a und dem eigentlichen Trockenfiltermaterial 4b. Das Filtermaterial ist vorzugsweise ein Vlies, günstigerweise ein Polyestervlies oder Glasfaservlies, welches eine Höhe von typischerweise einigen Zentimetern aufweist. Der Träger 4a kann mit Löchern 11 versehen sein, wie dies die Unteransicht der Fig. 2b darstellt. Günstigerweise besteht der Träger aus Fördergutmaterial, beispielsweise faserverstärktem Gummi. Es ist auch möglich, den Träger 4a aus einem luftdurchlässigen Gewebe (also ohne diskrete Löcher 11) auszubilden.The dry filter 4 is advantageously formed in two parts, namely from an air-permeable, statically stable but nevertheless flexible carrier 4a and the actual dry filter material 4b. The filter material is preferably a fleece, advantageously a polyester fleece or glass fiber fleece, which typically has a height of a few centimeters. The carrier 4a can be provided with holes 11, as shown in the bottom view of FIG. 2b. The carrier advantageously consists of material to be conveyed, for example fiber-reinforced rubber. It is also possible to form the carrier 4a from an air-permeable fabric (that is to say without discrete holes 11).

Zum Verbinden des Trägers 4a mit dem eigentlichen Filtermaterial 4b ist es günstig, diese miteinander zu verkleben.To connect the carrier 4a to the actual filter material 4b, it is advantageous to glue them together.

Um eine Führung des umlaufenden Trockenfilters 4 zu ermöglichen, sind beim Ausführungsbeispiel der Fig. 2a, 2b an der Hinterseite des Trockenfilters 4 zwei Führungsvorsprünge 12 ausgebildet. Diese Führungsvorsprünge 12 können dann in entsprechenden Führungsnuten (nicht dargestellt) der Umlenkrollen 5 geführt sein und führen dann den umlaufenden Trockenfilter 4 in Querrichtung.In order to enable the circulating dry filter 4 to be guided, two guide projections 12 are formed on the rear side of the dry filter 4 in the exemplary embodiment in FIGS. 2a, 2b. These guide projections 12 can then be guided in corresponding guide grooves (not shown) in the deflection rollers 5 and then guide the rotating dry filter 4 in the transverse direction.

Zur Führung des umlaufenden Trockenfilters 4 und für einen exakten Antrieb desselben, ist beim Ausführungsbeispiel gemäß der Fig. 3 vorgesehen, daß der Träger 4a zumindest eine Lochreihe 13 aufweist, in die Stifte 14 eingreifen, welche an der als Antriebsrad ausgebildeten Führungsrolle 5 angeordnet sind. Das Antriebsrad 5 wird von einem darüberliegenden Elektromotor 15 gegebenenfalls über ein nicht dargestelltes Getriebe angetrieben. Der Elektromotor 15 wird von einer Steuereinrichtung 16 gesteuert.For guiding the rotating dry filter 4 and for an exact drive thereof, it is provided in the exemplary embodiment according to FIG. 3 that the carrier 4a has at least one row of holes 13 into which pins 14 engage, which are arranged on the guide roller 5 designed as a drive wheel. The drive wheel 5 is driven by an overlying electric motor 15, possibly via a gear, not shown. The electric motor 15 is controlled by a control device 16.

Bei dem in Fig. 4 dargestellten Ausführungsbeispiel läuft der Trockenfilter 4 ebenfalls in horizontaler Richtung um. Die Führung in vertikaler Richtung erfolgt dadurch, daß der Trockenfilter 4 oben Führungselemente 17 aufweist, die in einer stationären horizontalen Führungsschiene 18 (ähnlich einer Vorhangschiene) geführt sind. Die Führungsschiene 18 kann oberhalb des Trockenfilters endlos im gesamten Umfang geführt sein. Es ist aber auch möglich, diese Führungsschiene 18 nur im vorderen Bereich und hinteren Bereich anzuordnen und die vertikale Führung im Bereich der Umlenkrollen 5 durch andere Mittel, beispielsweise durch die in die Lochreihen 13 eingreifenden Stifte 14 zu bewerkstelligen.In the embodiment shown in FIG. 4, the dry filter 4 also rotates in the horizontal direction. The guidance in the vertical direction takes place in that the dry filter 4 has guide elements 17 at the top, which are guided in a stationary horizontal guide rail 18 (similar to a curtain rail). The guide rail 18 can be guided endlessly over the entire circumference above the dry filter. However, it is also possible to arrange this guide rail 18 only in the front area and in the rear area and to achieve vertical guidance in the area of the deflection rollers 5 by other means, for example by the pins 14 engaging in the rows of holes 13.

Die Fig. 5 zeigt eine Einrichtung zum spritzlackieren eines Autos 19. Hier ist der Trockenfilter 4 horizontal ausgerichtet und läuft unterhalb der Spritzkabine 20.FIG. 5 shows a device for spray painting a car 19. Here, the dry filter 4 is aligned horizontally and runs below the spray booth 20.

Bei dem in Fig. 6 dargestellten Ausführungsbeispiel wird die Einsaugöffnung 7 der Absaugeinrichtung quer zur Bewegungsrichtung 21 des Trockenfilters 4 bewegt. Dies hat den Vorteil, daß man eine kleine Saugdüse 6a mit hoher lokaler Saugleistung einsetzen kann, um die getrockneten Lackpartikel vom Trockenfilter 4 abzusaugen. Die Saugdüse 6a ist über einen flexiblen Schlauch 6b mit der Saugeinheit 6c der Absaugeinrichtung verbunden. Es sind zwei feste Führungsschienen 22 vorgesehen, die die Saugdüse 6a führen. Die Bewegung der Saugdüse 6a in vertikaler Richtung in Fig. 6 erfolgt vorzugsweise über einen nicht dargestellten motorischen Antrieb, beispielsweise über einen Seilzugantrieb, einen Spindelantrieb, einen Zahnstangenantrieb od. dgl..In the embodiment shown in FIG. 6, the suction opening 7 of the suction device is moved transversely to the direction of movement 21 of the dry filter 4. This has the advantage that a small suction nozzle 6a with high local suction power can be used to suck the dried paint particles from the dry filter 4. The suction nozzle 6a is connected to the suction unit 6c of the suction device via a flexible hose 6b. There are two fixed guide rails 22 which guide the suction nozzle 6a. The movement of the suction nozzle 6a in the vertical direction in FIG. 6 preferably takes place via a motor drive (not shown), for example via a cable drive, a spindle drive, a rack drive or the like.

Im allgemeinen wird man mit dem bloßen Absaugen das Auslangen finden. Für besonders gelagerte Fälle ist es aber auch möglich, an der Hinterseite (Seite des Trägers 4a) des Transportbandes 4 eine Einrichtung 23 zum mechanischen Klopfen auf den Trockenfilter 4 anzuordnen, um die Lackpartikel besser von diesem lösen zu können. Diese Einrichtung 23 kann außerdem zum Erzeugen eines Luftstromes dienen, der von Hinterseite des Trockenfilters 4 zur Vorderseite gerichtet ist und damit die Absaugluftbewegung unterstützt.In general, you will find enough to do with just vacuuming. For particularly stored cases, however, it is also possible to arrange a device 23 for mechanical tapping on the dry filter 4 on the rear side (side of the carrier 4a) of the conveyor belt 4, in order to be able to better detach the paint particles from the latter. This device 23 can also be used to generate an air flow which is directed from the rear of the dry filter 4 to the front and thus supports the suction air movement.
