Definitions
- the invention relates to a method for operating a media conveyor system, in particular painting plant, with at least one reservoir for a medium that by means of a control unit in a delivery line is fed and by means of a pumping unit in a pumping direction is transported to a dispensing unit, wherein for a Cleaning process fed a cleaning medium in the delivery line becomes.
- Processes of this type find particular application in the paint industry, where paint shops, for example, the painting of body parts serve in motor vehicles, with the pending paint job by hand, but also by means of machines, such as painting robots or like, can be done.
- a requirement for pertinent paint shops It is often the type of paint (metallic paints) and / or the color to change accordingly.
- paint systems (DE 199 37 474 C2) with a gun unit, are applied to the paint on a workpiece can, with a color changer, connect to the at least two paint feeders are connected, with a connecting device, with the gun unit and the color changer together are connected, with a gun unit associated pig station, with a pig station assigned to the color changing device and a pig, which during a cleaning phase of the Pistol unit associated pig station through the connecting device through in the color changing device associated pig station and can be moved back again.
- the paint transport to the dispensing unit means a pump unit in the form of a gear pump or the like done, which due to the predetermined pump power to large Transport quantities can lead to paint mecanictragendem what in the Lackieranlagen with cleaning pig does not work, since the pertinent Displacer (pig) not through the gear pump through could be transported; despite this circumstance is the well-known, on the use of a pig dispensing pumping solution disadvantageous in this respect, as by the use of inert gas (nitrogen) first an inert gas source is to create, which in turn with correspondingly high costs acquisition and operation, since the spent inert gas for the cleaning process is always nachzubelves.
- inert gas nitrogen
- the invention has the object to further improve the known methods, that, while maintaining their good cleaning results, these but more reliable perform at low cost.
- a pertinent one Task solves a method with the features of the claim 1 in its entirety.
- the entry of the pertinent cleaning medium can inert gas-free, so that on an expensive supply and Nachbeforatung on inert gas (nitrogen) in the method according to the invention can be completely dispensed with.
- the method with anyway operated device-side components such that the cleaning medium does not unintentionally reach the reservoir side, but rather that here before a discharge from the delivery line takes place.
- the inventive method does not need to be limited to the application of paint shops, but is basically suitable for all types of in a delivery line too transporting media, which may be contaminants in the delivery line or in the subsequently arranged dispensing unit to lead.
- compressed air is used as the cleaning medium or, assisted by compressed air, the cleaning medium is transported in the conveying line.
- the cleaning medium is preferably a solvent

Abstract
Description
Nach einer bevorzugten Ausführungsform des erfindungsgemäßen Verfahrens wird das Medienvolumen zum Dosieren und Rückgewinnen durch die Pumpeinheit bewirkt. In einer Steuereinheit der Pumpeinheit werden die vorgesehenen Ansteuerzeiten bestimmt, um das Dosieren und Rückgewinnen des Mediumvolumens durchzuführen. Dadurch kann mit einer Einheit in Förderrichtung und in umgekehrter Richtung das Medienvolumen in der Förderleitung transportiert werden. Alternativ ist nach einer erfindungsgemäßen Ausführungsform des Verfahrens vorgesehen, dass zum Dosieren ein Mediendruckregler angesteuert und zum Rückgewinnen die Pumpeinheit angesteuert wird. Dadurch können die beiden Strömungsrichtungen des Medienvolumens durch unterschiedliche Einheiten gesteuert und überwacht werden.
Da das Reinigungsmedium nicht auf die Vorratsseite des Mediums gelangen soll, muss ermittelt werden, wie viel Reinigungsmedium in der Fördereinheit transportiert wird, bevor diese die Steuereinheit erreicht, an der die Medienvorratsseite angeschlossen ist. Hierbei wird das Pumpenvolumen, die Drehzahl der Pumpe sowie das in der Förderleitung befindliche Volumen (Fläche x Länge der Förderleistung) berücksichtigt. Dies dient der kontrollierten Rückführung der Farbe in die Vorratsbehälter. So wird jedenfalls sichergestellt, dass die Steuereinheit vorher sperrt und das Reinigungsmedium dann über eine Abzweigleitung, die über eine weitere Ventileinheit ansteuerbar ist, das eigentliche Auftragssystem mit Förderleitung verlässt, wobei die dahingehenden Medienreste nebst Reinigungsmedium in einem Sammelbehälter bevorratbar sind. Gegebenfalls besteht die Möglichkeit, das Reinigungsmedium, insbesondere, wenn es sich um ein lösemittelhaltiges handeln sollte, dergestalt von den sonstigen abgereinigten Farbresten zu trennen, um das Reinigungsmedium der Anlage wieder zuführen zu können. Dies kommt der Umwelt zugute und spart Betriebskosten.
