Abstract
Description
Die vorliegende Erfindung betrifft ein System zur Zuführung mehrere Farbkomponenten für mindestens eine Lackierstation, insbesondere für Kraftfahrzeugkaroserien nach den Merkmalen des Oberbegriffs des Anspruchs 1.The The present invention relates to a system for feeding a plurality Color components for at least one painting station, in particular for motor vehicle bodies the features of the preamble of claim 1.
Lackieranlagen verwenden meist pneumatischangetriebene Kolbenpumpen zum Fördern der Farbkomponenten bzw. Farben. Sofern nachfolgend von Farbkomponenten gesprochen wird, sind sowohl fertig gemischte Farben als auch Farbkomponenten gemeint, die mit anderen Farbkomponenten gemischt eine neue Farbe ergeben.paint shops usually use pneumatically driven piston pumps to convey the color components or colors. If below is spoken of color components, are meant both ready mixed colors and color components, mixed with other color components to give a new color.
Ein großer Kostenpunkt in herkömmlichen Lackieranlagen ist die Druckluftversorgung für die Förderpumpen, da Druckluft eine sehr teure Energiequelle ist. Hydraulisch angetriebene Pumpen weisen Nachteile auf, die ihren Einsatz nur bedingt zulassen.One greater Cost in conventional paint shops is the compressed air supply for the feed pumps, compressed air is a very expensive source of energy. Hydraulically driven Pumps have disadvantages that allow their use only conditionally.
In einer Lackieranlage z.B. in der Fahrzeugproduktion, mit 30 Farben bzw. Farbkomponenten müssen 30 große Förderpumpen die Lackkomponenten in Ringleitungen bewegen und die Entnahmestellen mit dem nötigen Einspeisedruck versorgen. Bei einer Durchflussmenge von ca. 10 Ltr./min/Strang ergibt sich ein Luftbedarf von mindestens 450 NLtr./min. Pro Tag entspricht dies ca. 20.000 NM3, pro Jahr ca. 7,3 Mio. Nm3. Bei Kosten von 0,10 EUR/Nm3 entspricht die einem Kostenaufwand von 730.000 EUR/Jahr.In a paint shop, for example in vehicle production, with 30 colors or color components, 30 large feed pumps have to move the paint components in ring lines and supply the tapping points with the necessary feed pressure. At a flow rate of approx. 10 ltr./min/strength, the air requirement is at least 450 NLtr./min. This corresponds to approx. 20,000 NM 3 per day, approx. 7.3 million Nm 3 per year. At a cost of 0.10 EUR / Nm 3, this equates to a cost of 730,000 EUR / year.
Bei
den heutigen Systemen, wie sie beispielhaft in
Die
Fördermenge
der Pumpen
Das vorbeschriebene System zur Bereitstellung von Farbkomponenten für Lackieranlagen arbeitet energetisch ungünstig und ist daher teuer in der Anwendung.The above-described system for the provision of paint components for paint shops works energetically unfavorable and is therefore expensive to use.
Aufgabe der vorliegenden Erfindung ist daher, die Energiekosten des Systems zu verringern.task Therefore, the present invention is the energy cost of the system to reduce.
Diese
Aufgabe wird erfindungsgemäß dadurch
gelöst,
dass die Fördermenge
und/oder der Förderdruck
bei all den Farbkomponenten reduziert wird, die momentan in den
Lackierstationen nicht benötigt
werden. Dies wird dadurch möglich,
dass die Förderleistung
der Förderpumpen
und der Förderdruck über eine
Steuerung des Systems einstellen läst. Hierzu werden im einfachsten
Fall die vorhandenen Pumpenregler
Durch die Erfindung kann der Volumenstrom der Farbkomponenten, die nicht benötigt werden, d.h. sich in der Rezirkulation befinden, vorteilhaft auf ein erforderliches Minimum reduziert werden, ohne dass sich Farbpartikel absetzen können und es zu einer Inhomogenität der Farbkomponente kommt. Durch das Öffnen des Druckreglers in der Rezirkulationsphase kann der erforderliche Energieaufwand für das Fördern der Farbkomponente weiter minimiert werden. Da idR nur drei von dreißig zur Verfügung stehenden Farbkomponenten zur gleichen Zeit benötigt, d.h. bereitgestellt werden müssen, ergibt sich durch das Absenken der Förderleistung und des Förderdrucks der übrigen 27 Farbkomponenten ein sehr großes Energieeinsparungspotential.By The invention can reduce the volume flow of the paint components that are not needed are, i. are in the recirculation, beneficial to one required minimum can be reduced without leaving any color particles can settle and it's inhomogeneity the color component comes. By opening the pressure regulator in the Recirculation phase can reduce the energy required to promote the Color component can be further minimized. As a rule, only three out of thirty to disposal standing color components at the same time, i. to be provided have to, results from lowering the delivery rate and delivery pressure the rest 27 color components a very large Energy saving potential.
Mit der erfindungsgemäßen intelligenten Energieverwaltung werden somit vorteilhaft nur die Stränge bzw. Farbkomponenten mit den erforderlichen Arbeitsdrücken und -mengen eingestellt, die für die Produktion gefordert sind. Alle anderen Stränge laufen mit geringem Druck und der erforderlichen Minimalmenge in Rezirkulation, um ein Absetzen von z.B. Metallpigmenten zu verhindern.With the inventive intelligent Power management are thus advantageous only the strands or Set color components with the required working pressures and quantities, the for the Production are required. All other strands run with low pressure and the required minimum amount in recirculation to settle from e.g. Prevent metal pigments.
Anhand der Produktionsdaten kann das System bedarfsgerecht die Volumenströme und Arbeitsdrücke der einzelnen Farbkomponenten einstellen bzw. einregeln. Die Produktionsdaten umfassen dabei zumindest die Informationen, welche Farbkomponenten gerade in welcher Lackierstation zu verspritzen sind. Auch kann das System vorausschauend die Produktionsdaten auswerten, so dass z.B. die Förderleistung und/oder der Arbeitsdruck einer Farbkomponenten nur geringfügig oder z.T. abgesenkt wird, sofern nur kurzeitig die Farbkomponente nicht benötigt wird. Dies ist z.B. immer dann der Fall, wenn ein Fahrzeug rot und erst das übernächste oder über-übernächste Fahrzeug wieder rot lackiert werden muß. In diesem Fall könnte es aus verschiedensten Gründen, wie z.B. Einschwingvorgängen, ungünstig sein, wenn der Förderdruck und die Förderleistung der roten Farbkomponente unmittelbar nach dem Fertigspritzen des ersten roten Fahrzeuges für die Dauer des Spritzvorganges für das gelbe Fahrzeug auf ein erforderliches Minimum reduziert wird.Based on the production data, the system can adjust or regulate the volume flows and working pressures of the individual color components as needed. The production data include at least the information as to which color components are to be sprayed in which painting station. Also, the system can proactively evaluate the production data, so that eg the För the performance and / or the working pressure of a color components is only slightly or partially lowered, if only briefly the color component is not needed. This is always the case, for example, when a vehicle is red and only the next but one or over-next vehicle must be painted red again. In this case, for a variety of reasons, such as transients, it may be inconvenient to reduce the delivery pressure and delivery of the red color component to a required minimum immediately after pre-injection of the first red vehicle for the duration of the yellow vehicle spraying operation.
Das erfindungsgemäße System baut gerätetechnisch auf dem bekannten System auf und nutzt all dessen Komponenten, so dass nur ein geringer Investitionsbedarf notwendig ist, um das bekannte System auf das erfindungsgemäße System umzurüsten.The inventive system builds device technology on the known system and uses all its components, so that only a small investment requirement is necessary to the well-known System on the system according to the invention convert.

Aus
den Produktionsdaten kann die Steuerung
Neben den genannten Vorteilen kann ein weiterer Nutzen aus dem erfindungsgemäßen System gezogen werden. Mit der Intelligenz des Energiemanagements können auch die Zustände der Pumpen, Regler, Ventile, Leitungen und Filter des Systems überwacht werden. Läuft z.B. eine Pumpe schwergängig, kann dies durch den einzustellenden Luftdruck und der daraus resultierenden Hubfrequenz ausgewertet werden. Je nach erkanntem Zustand kann das Wartungsintervall für die jeweilige Pumpe geändert oder deren Wartungsintervall neu bestimmt werden. Auch können Signale bzw. Informationen an übergeordnete Systeme oder Stellen geleitet werden um weitere Maßnahmen einzuleiten. Hierdurch können Produktionsstillstände durch vorbeugende Maßnahmen vorteilhaft vermieden werden.Next The advantages mentioned can be a further benefit of the system according to the invention to be pulled. With the intelligence of energy management can also the conditions monitors the pumps, regulators, valves, lines and filters of the system become. Running e.g. a pump stiff, This can be done by adjusting the air pressure and the resulting Hub frequency are evaluated. Depending on the detected condition that can Maintenance interval for changed the respective pump or whose maintenance interval is to be redetermined. Also can signals or information to higher level Systems or bodies are headed for further action initiate. This allows Production shutdowns through preventive measures be avoided advantageous.
