Abstract
Description
Die Erfindung betrifft eine Vorrichtung zum Reinigen wenigstens einer Applikationsdüse, insbesondere einer PVC-Applikationsdüse. Ferner betrifft die Erfindung ein Verfahren zum Reinigen von Applikationsdüsen.The invention relates to a device for cleaning at least one application nozzle, in particular a PVC application nozzle. Furthermore, the invention relates to a method for cleaning application nozzles.
Beim PVC-Applikationsverfahren zur Abdichtung und dem Korrosionsschutz von Karosserien, insbesondere Kfz-Karosserien, kommt es verbreitet prozessbedingt zu Verschmutzungen durch Verschleppung des verwendeten PVC. Das PVC bleibt beispielsweise an der Applikationsdüse haften. Weitere Beeinträchtigungen bestehen in einer Verschmutzung der Karosserien, Qualitätsmängeln durch unsaubere PVC-Nähte bis hin zum Versagen der PVC-Nähte im Hinblick auf deren Dichtigkeit. Ferner bestehen Vermessungsprobleme der Applikationsdüse und dadurch ein erheblicher Reinigungsaufwand mit hohen Ausfallzeiten der Produktionsanlage.With the PVC application method for sealing and corrosion protection of bodies, in particular motor vehicle bodies, it is common process-related contamination by carryover of the PVC used. The PVC, for example, adheres to the application nozzle. Further impairments consist of soiling of the bodies, quality defects due to unclean PVC seams and failure of the PVC seams in terms of their tightness. Furthermore, there are surveying problems of the application nozzle and thus a considerable cleaning effort with high downtime of the production plant.
Bedingt durch bisher angewandte Applikationsverfahren sind Reinigungsverfahren für Applikationsdüsen in einer Vielzahl verschiedener Ausführungen bekannt. Diese funktionieren in der Regel jedoch alle nach dem gleichen Grundprinzip. Durch die Verwendung von Pressluft und entsprechender Düsen wird versucht, PVC-Verschmutzungen an der Applikationsdüse zu entfernen. Diese Verfahren haben jedoch Nachteile in der Wirksamkeit der Reinigung.Due to previously applied application methods cleaning methods for application nozzles in a variety of different designs are known. However, these usually all work according to the same basic principle. The use of compressed air and corresponding nozzles attempts to remove PVC contamination from the application nozzle. However, these methods have disadvantages in the effectiveness of the cleaning.
Es ist daher Aufgabe der vorliegenden Erfindung, eine Vorrichtung zum Reinigen von Applikationsdüsen und ein Verfahren zum Reinigen von Applikationsdüsen zur Verfügung zu stellen, die eine verbesserte Reinigung der Applikationsdüsen ermöglichen.It is therefore an object of the present invention to provide a device for cleaning application nozzles and a method for cleaning application nozzles, which enable improved cleaning of the application nozzles.
Diese Aufgabe wird durch eine Vorrichtung und ein Verfahren mit den Merkmalen der unabhängigen Patentansprüche gelöst. Vorteilhafte Ausgestaltungen mit zweckmäßigen und nicht-trivialen Weiterbildungen der Erfindung sind in den Unteransprüchen angegeben.This object is achieved by an apparatus and a method having the features of the independent claims. Advantageous embodiments with expedient and non-trivial developments of the invention are specified in the subclaims.
Gemäß einem Aspekt der Erfindung weist eine Vorrichtung zum Reinigen wenigstens einer Applikationsdüse, insbesondere PVC-Applikationsdüse, eine Zerstäuberdüse zum Bestrahlen der Applikationsdüse mit einem Gemisch aus Luft und einem Weichmacher auf. Ferner weist die Vorrichtung eine Saugeinrichtung zum Absaugen des aus der Zerstäuberdüse ausgestoßenen Gemischs auf. Durch die Zuführung des Weichmachers zur der Luft, die zum Bestrahlen der Applikationsdüse verwendet wird, wird eine erhöhte Reinigungswirkung erzielt. Der beim Bestrahlen der Applikationsdüse entstehende Nebel aus Luft, Weichmacher und gegebenenfalls Verunreinigungen wird durch die Saugeinrichtung abgesaugt.According to one aspect of the invention, an apparatus for cleaning at least one application nozzle, in particular a PVC application nozzle, has an atomizer nozzle for irradiating the application nozzle with a mixture of air and a plasticizer. Furthermore, the device has a suction device for sucking off the mixture ejected from the atomizer nozzle. By supplying the plasticizer to the air, which is used to irradiate the application nozzle, an increased cleaning effect is achieved. The resulting from irradiation of the application nozzle mist of air, plasticizer and any impurities is sucked through the suction device.
Der Weichmacher kann mittels der Saugeinrichtung aus dem Gemisch aus Luft und Weichmacher extrahiert und dann wieder verwendet werden. Hierdurch wird es möglich, PVC-Applikationsdüsen im automatisierten Betrieb ohne Demontage einer Reinigung zu unterziehen. Durch das Reinigungsverfahren mit der erfindungsgemäßen Vorrichtung ergeben sich Vorteile hinsichtlich einer Minimierung des Störaufkommens. Ein weiterer Vorteil liegt in einer Qualitätssteigerung bedingt dadurch, dass Probleme, die durch das Verschleppen des PVC (Polyvinylchlorid) verursacht werden, minimiert werden. Hierdurch kann ein robusterer Produktionsprozess und eine verbesserte Produktionsqualität erzielt werden.The plasticizer can be extracted by means of the suction device from the mixture of air and plasticizer and then reused. This makes it possible to subject PVC application nozzles in automated operation without disassembly of a cleaning. By the cleaning method with the device according to the invention, there are advantages in terms of minimizing the disturbance. Another advantage is an increase in quality due to the fact that problems caused by the carryover of the PVC (polyvinyl chloride) are minimized. This allows a more robust production process and improved production quality.
Gemäß einer Ausführungsform weist die Saugeinrichtung einen Filter, insbesondere einen Siebfilter, auf. Der Filter ermöglicht ein Abscheiden des Weichmachers und von PVC. Der Weichmacher und das PVC können dadurch aus dem Gemisch aus Luft und Weichmacher separiert und einer Wiederverwendung zugeführt werden.According to one embodiment, the suction device has a filter, in particular a sieve filter. The filter allows the plasticizer and PVC to be separated. The plasticizer and the PVC can thereby be separated from the mixture of air and plasticizer and fed to a reuse.
Gemäß einer weiteren Ausführungsform weist die Saugeinrichtung einen dem Filter nachgeschalteten Auffangbehälter auf. Der Auffangbehälter ist beispielsweise unterhalb des Filters angeordnet. Der Auffangbehälter ermöglicht das Auffangen, Absetzen und Abtropfen des Weichmachers, so dass dieser wieder verwendet werden kann.According to a further embodiment, the suction device has a collecting container downstream of the filter. The collecting container is arranged, for example, below the filter. The container allows the collection, settling and dripping of the plasticizer so that it can be reused.
Gemäß einer weiteren Ausführungsform ist eine Dosiereinrichtung zum Beimengen des Weichmachers zur Luft der Zerstäuberdüse vorgeschaltet vorgesehen. Die Dosiereinrichtung ermöglicht eine einstellbare Zudosierung und Beimengung des Weichmachers zur Luft. Damit kann das Verhältnis aus Luft und Weichmacher, das zur Zerstäuberdüse zugeführt wird, eingestellt werden.According to a further embodiment, a metering device for adding the plasticizer to the air upstream of the atomizer nozzle is provided. The metering device allows an adjustable metering and admixture of the plasticizer to the air. Thus, the ratio of air and plasticizer supplied to the atomizer nozzle can be adjusted.
Ein erfindungsgemäßes Verfahren zum Reinigen von Applikationsdüsen weist die Verfahrensschritte:
- – Bestrahlen wenigstens einer Applikationsdüse mit einem Gemisch aus Luft und einem Weichmacher und
- – Absaugen des Gemischs mittels einer Saugeinrichtung während des Bestrahlens
- - Irradiating at least one application nozzle with a mixture of air and a plasticizer and
- - Sucking off the mixture by means of a suction device during irradiation
Das abgesaugte Gemischt kann dann durch einen Filter, insbesondere einen Siebfilter, geleitet werden. Vom Filter abtropfender Weichmacher kann zur Wiederverwendung in einem Auffangbehälter gesammelt werden.The extracted mixture can then be passed through a filter, in particular a sieve filter. Plasticizer dripping from the filter can be collected for reuse in a collection container.
Weitere Vorteile, Merkmale und Einzelheiten der Erfindung ergeben sich aus der nachfolgenden Beschreibung bevorzugter Ausführungsbeispiele sowie anhand der Zeichnung; diese zeigt in der einzigen Figur eine schematische Querschnittsdarstellung einer Vorrichtung zum Reinigen von Applikationsdüsen.Further advantages, features and details of the invention will become apparent from the following description of preferred embodiments and from the drawing; this shows in the single figure a schematic cross-sectional view of a device for cleaning application nozzles.
