Abstract

The invention relates to a plant for colour spraying series-production parts of changing colour with a preferably machine-guided spray gun. The paint-conducting duct to the spray gun can be occluded at different colours by a colour change valve block. During a colour change, the cavities which conduct paint are first rinsed free with solvent and the solvent is trapped in a collection container without mixing with air from the surroundings. For this purpose, a solvent duct is separately placed on the outer periphery of the spray gun. In order to clean a paint filter arranged in the paint-conducting duct as frequently as possible, i.e. at least at each colour change or possibly even more frequently, as thoroughly as possible, the throughflow direction of the solvent during rinsing is opposite to the throughflow direction of the paint during painting.

Description

Anlage zum Farbspritzen von Serienteilen System for paint spraying of series parts

wechselnder Farbe Die Erfindung betrifft eine Anlage zum Farbspritzen von Serienteilen wechselnder Farbe nach dem Oberbegriff des Patentanspruches wie sie beispielsweise aus der DE-OS 27 -47 707 als bekannt hervorgeht. changing color The invention relates to an installation for paint spraying of serial parts of changing color according to the preamble of the patent claim such as it emerges, for example, from DE-OS 27-47 707 as known.

Zum Schutz der Farbzerstäubungseinrichtung und des Werkstückes gegen Farbverunreinigungen und Farbbatzen sind in den Farbleitungen Farbfilter angebracht, um diese Partikel zurückzuhalten. Hierbei kann es leicht, insbesondere beim Verarbeiten von Metallic-Lacken, zu Filterverstopfungen kommen. Die Filter müssen dann umständlich demontiert, gereinigt und wieder eingebaut werden, was mit Zeitverlust verbunden ist. Zudem können vom Filter zurückgehaltene Agglomerate sich allmählich durch die Filtermaschen zwängen. Diese gelangen dann trotz Filterung der Farbe auf das Werkstück und verursachen Ausbesserungsarbeiten an der Lackierung.To protect the paint atomizer and the workpiece against Color impurities and chunks of color are attached to the color lines in the color filter, to hold back these particles. This can be easy, especially when processing from metallic paints to filter blockages. The filters then have to be cumbersome dismantled, cleaned and reinstalled, which is associated with loss of time is. In addition, agglomerates retained by the filter can gradually spread through the Force filter mesh. These then get onto the workpiece despite the filtering of the color and cause repairs to the paintwork.

Aufgabe der Erfindung ist es, die zugrunde gelegte Anlage zum Farbspritzen dahingehend auszugestalten, daß derartige Arbeiten zur Wartung der Farbfilter und zum Ausbessern der Lackierung entbehrlich sind.The object of the invention is to provide the underlying system for paint spraying to the effect that such work for the maintenance of the color filters and are unnecessary for touching up the paintwork.

Diese Aufgabe wird erfindungsgemäß durch die kennzeichnenden Merkmale des Patentanspruchs gelöst. Dank der Anordnung des Farbfilters in der Verbindungsleitung zwischen dem Farbwechselventilblock und der Farbzerstäubungseinrichtung wird dieser bei jedem Farbwechsel mit gereinigt; aufgrund der umgekehrten Spülrichtung werden die Filteranlagerungen immer nach rückwärts von dem filterwirksamen Material abgelöst und in dem Sammelbehälter zurückgeschwemmt.According to the invention, this object is achieved by the characterizing features of the claim solved. Thanks to the arrangement of the color filter in the connection line between the color change valve block and the paint atomization device this is cleaned with every color change; due to the reversed flushing direction the filter deposits are always detached backwards from the filter-effective material and washed back in the sump.

Weil ein Farbwechsel relativ häufig vorkommt, können sich Filterverstopfungen praktisch nicht mehr bilden, weil das Farbfilter in relativ kurzen Intervallen ständig wieder gereinigt wird. Auch schleimartige Farbbatzen können sich nicht durch die Poren des Filters hindurchzwängen, weil derartige Partikel in einem relativ frühen Stadium ebenfalls nach rückwärts aus dem Filter wieder hinausgetragen werden.Because a color change occurs relatively frequently, the filter can become clogged practically no longer form, because the color filter is constantly in relatively short intervals is cleaned again. Even slime-like lumps of paint cannot get through the Forcing through pores of the filter, because such particles in a relatively early Stage can also be carried backwards out of the filter.

Die Erfindung ist anhand eines in der Zeichnung dargestellten Ausführungsbeispieles nachfolgend noch kurz erläutert; dabei zeigt die einzige Figur ein auf das wesentliche beschränktesSchaltschema für eine Farbspritsanlage für eine maschinengeführte Farbspritzpistole.The invention is based on an embodiment shown in the drawing briefly explained below; the single figure shows what is essential Limited circuit diagram for a paint spray system for a machine-guided paint spray gun.

In der Zeichnung ist eine Farbspritzpistole 1 angedeutet, die von einem Farbroboter oder einer ähnlichen maschinellen Einrichtung über ein Werkstück hinwegführbar ist. Sie weist eine Ventilnadel 2 und einen ringförmigen farbführenden Hohlraum 3 auf. In der Farbzufuhr zu dieser Farbzerstäubungseinrichtung ist ein Farbwechselventilblock 4 mit mehreren Einzelventilen 5 angeordnet, der über eine farbführende Leitung 6 und eine als Zahnradpumpe 17 ausgebildete Dosier- pumpe mit der Farbzerstäubungseinrichtung verbunden ist.In the drawing, a paint spray gun 1 is indicated, which of a color robot or a similar machine device over a workpiece is feasible. It has a valve needle 2 and an annular paint-carrying one Cavity 3. In the paint supply to this paint atomizer is a Color change valve block 4 arranged with several individual valves 5, which has a paint-carrying line 6 and a metering pump designed as a gear pump 17 pump is connected to the paint atomization device.

Jedes der Einzelventile 5 ist mit einer anderen Farbe verbunden, so daß sich durch jedes der Einzelventile eine andere Farbe der Farbzerstäubungseinrichtung zuführen läßt.Each of the individual valves 5 is associated with a different color, see above that each of the individual valves has a different color of the atomizing device can be fed.

Mit der volumetrisch wirkenden Zahnradpumpe läßt sich ungeachtet etwaiger Schwankungen der Farbviskosität, der Temperatur oder des Vordruckes die Farbmenge sehr feinfühlig dosieren. Während des Lackierbetriebes strömt die Farbe in Pfeilrichtung 15 durch die farbführende Leitung 6 und den in dieser Leitung angeordneten Farbfilter 14 zu der Farbzers täubungs einrichtung.With the volumetrically acting gear pump, regardless of any Fluctuations in the ink viscosity, the temperature or the pre-pressure the amount of ink dose very sensitively. During the paint shop, the paint flows in the direction of the arrow 15 through the color-carrying line 6 and the color filter arranged in this line 14 to the color deadening device.

Vor einem Farbwechsel müssen die farbführende Leitung und der ringförmige Hohlraum 3 innerhalb der Farbzerstäubungseinrichtung von Altfarbe freigespült werden. Zu diesem Zweck ist eine Lösungsmittelleitung 10 an den ringförmigen Hohlraum angeschlossen, wobei der Anschluß dieser Leitung gegenüber dem Anschluß der farbführenden Leitung in Axialrichtung und/oder in Umfangsrichtung versetzt in dem ringförmigen Hohlraum angeordnet ist, um eine gute Durchspülung und Reinigung dieses Raumes zu erreichen. Erfindungsgemäß ist die Durchspülrichtung 16 der Durchflußrichtung 15 beim Lackierbetrieb entgegengesetzt, um auf besondere wirkungsvolle Weise das Farbfilter 14 reinigen zu können.Before a color change, the color-carrying line and the ring-shaped Cavity 3 are flushed free of old paint within the paint atomization device. For this purpose, a solvent line 10 is connected to the annular cavity, the connection of this line opposite the connection of the paint-carrying line offset in the axial direction and / or in the circumferential direction in the annular cavity is arranged in order to achieve a good flushing and cleaning of this room. According to the invention, the flushing direction 16 is the flow direction 15 during the painting operation on the other hand, in order to clean the color filter 14 in a particularly effective manner to be able to.

Zu diesem Zweck ist in unmittelbarer Nähe der Farbzerstäubungseinrichtung innerhalb der Lösungsmittelleitung 10 ein als Rückschlagventil ausgebildetes Ventil 11 angebracht.For this purpose, the paint atomizer is in the immediate vicinity within the solvent line 10 a valve designed as a check valve 11 attached.

Zur Sicherheit ist an der Übergangsstelle zwischen der Lösungsmittelleitung 10 und der Lösungsmittelzufuhr 8 noch ein steuerbares Lösungsmittelventil 7 angeordnet, welches bei einem verzögerten Ansprechen des Rückschlagventiles oder bei Undichtigkeit einen Farbaustritt und einen Lösungsmittelzulauf verhindert. Außerdem brauchen Steuerleitungen nicht bis in den Bereich der maschinenegeführten Farbspritzpistole zu verlaufen. Lösungsmittel und Druckluft aus einer Druckluftquelle 7' können gemischt oder in gezieltem Wechsel in die Lösungsmittelleitung 10 eingespeist werden; durch die Luftzumischung kann die Turbulenz und die Reinigungswirkung des Lösüngsmittels noch gesteigert werden. Außerdem können die zu reinigenden Hohlräume gegen Ende des Spülvorganges von Lösungsmittel freigeblasen werden, so daß sich die neu eintretende Farbe mit ihnen nicht verdünnt.To be on the safe side, it is at the transition point between the solvent line 10 and the solvent supply 8 a controllable solvent valve 7 is also arranged, which with a delayed response of the check valve or prevents paint leakage and solvent inflow in the event of a leak. In addition, control lines do not need to extend into the area of the machine-operated ones Paint spray gun to run. Solvent and compressed air from a compressed air source 7 ′ can be fed into the solvent line 10 in a mixed manner or in a targeted change will; by adding air, the turbulence and the cleaning effect of the Solvent can be increased. In addition, the cavities to be cleaned be blown free of solvent towards the end of the flushing process, so that the newly emerging color is not diluted with them.

Das Gemisch aus Lösungsmittel und Altfarbe, die aus dem ringförmigen Hohlraum 3, der farbführenden Leitung 6, dem Farbfilter 14, der Zahnradpumpe 17 und dem Farbwechselventilblock 4 ausgespült wird, kann über das steuerbare Ventil 13 und die Sammelleitung 12 in den Sammelbehälter 9 abgeleitet werden. Es kommt dadurch zu keiner nennenswerten Belastung der Umgebungsluft. Dank des den Zahneingriff der Pumpenzahnräder fluidisch überbrückenden Spülkanals 18, der durch Verschlußventile 19 schließbar ist, kann die Zahnradpumpe in relativ kurzer Zeit ebenfalls gründlich mit gereinigt werden, wobei der Lösungsmittelverbrauch nicht gesteigert zu werden braucht.The mixture of solvent and old paint that came out of the ring-shaped Cavity 3, the paint-carrying line 6, the paint filter 14, the gear pump 17 and the color change valve block 4 is flushed out, via the controllable valve 13 and the collecting line 12 are diverted into the collecting container 9. It is coming as a result, there is no significant pollution of the ambient air. Thanks to the meshing of the pump gears fluidically bridging flushing channel 18, which is through shut-off valves 19 can be closed, the gear pump can also be thorough in a relatively short time can also be cleaned, the solvent consumption not being increased needs.

Der Vorteil der Erfindung liegt in einer Reduzierung des Wartungsaufwandes für den Farbfilter und in der wirksamen Verhinderung des Hindurchquälens von schleimartigen Farbbatzen durch die Filterporen.The advantage of the invention is a reduction in maintenance costs for the color filter and in the effective prevention of torture of mucous Lumps of paint through the filter pores.
