The coating material supply method involves isolating the coating arrangement from the earthed supply system by air between a first swab (M1) and a second swab station (7) and by an isolating medium between a first swab station (3) and a second swab (M2), while the coating material is fed between the swabs via a feed line (8). AN Independent claim is also included for the following: a system for supplying coating material for electrostatic mass production coating of workpieces such as vehicle bodies.

Description

Die Erfindung betrifft ein Verfahren zur Versorgung einer Beschichtungsvorrichtung für die elektrostatische Serienbeschichtung von Werkstücken wie beispielsweise Fahrzeugkarossen gemäß dem Oberbegriff des Anspruchs 1 sowie ein entsprechendes Versorgungssystem.The invention relates to a method for supplying a coating device for electrostatic serial coating of workpieces such as vehicle bodies according to the preamble of claim 1 and a corresponding supply system.

Bei der elektrostatischen Serienbeschichtung von Werkstücken mit niederomigem Beschichtungsmaterial wie beispielsweise Wasserlack besteht bekanntlich das Problem der elektrischen Isolierung (Potentialtrennung) zwischen dem geerdeten Teil des Versorgungssystems, zu dem insbesondere die geerdete Farbwechselventilanordnung (Farbwechsler) gehört, und den zu versorgenden Zerstäubern insbesondere bei Direktaufladung des Beschichtungsmaterials durch die Beschichtungsorgane. Zu diesem Zweck sind u.a. verschiedene Verfahren bekannt, bei denen das Beschichtungsmaterial dem auf Hochspannung liegenden Zerstäuber aus einem geerdeten Behälter über abwechselnd auf Erd- und Hochspannungspotential gelegte Zwischenbehälter zugeführt werden kann (US 3122320, DE 2900660, US 4313475, EP 0292778 usw.). Die hierfür verwendeten Systeme sind u.a. wegen der Behältertechnik aufwendig und können aufgrund des hohen Platzbedarfs nur mit erheblichen Entfernungen vom Zerstäuber installiert werden. Diese Entfernungen und großvolumige Zwischenbehälter führen wiederum zu hohen Farb- und Spülmittelverlusten beim Farbwechsel.In the electrostatic serial coating of workpieces with niederomigem coating material such as water-based paint As is known, there is the problem of electrical insulation (Potential separation) between the earthed part of the Supply system, in particular the grounded color change valve assembly (Color changer), and to be supplied Atomizers in particular when directly charging the coating material through the coating organs. To this end are u.a. Various methods are known in which the coating material the high-voltage atomizer from a grounded container over alternately on earth and High voltage potential placed intermediate containers are supplied can (US 3122320, DE 2900660, US 4313475, EP 0292778 etc.). The systems used for this purpose are i.a. because of the container technology consuming and can due to the high space requirements only installed at considerable distances from the atomizer become. These distances and large-volume intermediate tanks lead in turn to high color and detergent losses Color change.

In neueren Beschichtungsanlagen hat sich bereits die Molchtechnik bewährt. Beispielsweise wird bei einer aus der EP 1 208 915 bzw. aus der DE 19830029 bekannten Anlage mit einem Versorgungssystem zum Beschichten von Fahrzeugkarossen mit häufig wechselnden Farben das Beschichtungsmaterial in der Reihenfolge der gewünschten Farben in eine Zuführleitung eingeführt und darin durch jeweils zwei Molchkörper voneinander getrennt, zwischen denen sich Reinigungsflüssigkeit als Isoliermedium zur Potentialtrennung befinden kann. Bei der Verwendung von Isolierflüssigkeiten besteht die Gefahr einer Kontamination des Beschichtungsmaterials.In newer coating systems, the pig technology already has proven. For example, in one of EP 1 208 915 or DE 19830029 known plant with a supply system for coating Of vehicle bodies with frequently changing colors the coating material in the order of the desired colors introduced into a feed line and therein by two Pig body separated from each other, between which cleaning fluid as insulation medium for potential separation can. When using insulating fluids the risk of contamination of the coating material.

Bekannt ist auch, eine Zuführleitung für elektrisch leitendes Beschichtungsmaterial zur Potentialtrennung mit einem hin und her bewegbaren Molchkörper zu reinigen (DE 19937426 und 19961271).Also known is a supply line for electrically conductive Coating material for potential separation with a down and to clean movable pig body (DE 19937426 and 19961271).

Ferner ist es aus der DE 19742588 bekannt, das Beschichtungsmaterial für die serienweise Beschichtung von Werkstücken mit einem Molch zu dem Applikationsorgan zu drücken, wobei der Molch seinerseits von dem Beschichtungsmaterial oder einer unter Druck stehenden Spülflüssigkeit beaufschlagt wird. Die zum Dosieren des Farbmaterials erforderliche Pumpe kann vor der gemolchten Leitung oder zwischen ihr und dem Applikationsorgan angeordnet sein.Furthermore, it is known from DE 19742588, the coating material for the serial coating of workpieces with to push a pig to the application organ, wherein the Pig in turn from the coating material or an under Pressurized flushing liquid is applied. The to Dosing the paint material required pump can be before the gemolchten Line or between it and the application organ be arranged.

EP 1 208 915 offenbart der Stand der Technik gemäß des Oberbegriffs der Ansprüche 1 und 9.EP 1 208 915 discloses the prior art according to the preamble of claims 1 and 9.

Aufgabe der Erfindung ist, eine sichere Potentialtrennung mit einem kompakten, auch in unmittelbarer Nähe der Zerstäuber ggf. innerhalb einer Beschichtungsmaschine installierbaren Versorgungssystem und mit entsprechend geringen Farbverlusten beim Farbwechsel zu ermöglichen.The object of the invention is a secure potential separation with a compact, even in the immediate vicinity of the atomizer if necessary within a coating machine installable supply system and with correspondingly low color losses during To allow color change.

Diese Aufgabe wird durch die Merkmale der Patentansprüche gelöst.This object is solved by the features of the claims.

Die Erfindung kommt ohne die bisher weitgehend übliche Zwischenbehältertechnik für Farbmaterial aus und vermeidet deren Nachteile. U.a. kann nicht benötigtes Farbmaterial problemlos zu der geerdeten Versorgungseinrichtung zurückgefördert werden. Vorteilhaft ist ferner, dass es zwar möglich, aber nicht notwendig ist, das Beschichtungsmaterial unter Verwendung einer Isolierflüssigkeit mit der erwähnten Kontaminationsgefahr zu dem Zerstäuber zu fördern. Zudem besteht die an sich bekannte Möglichkeit kontinuierlicher Beschichtung durch Wechselbetrieb mit zwei parallelen Leitungen (A/B-Betrieb), zwischen denen z. B. in den Pausen zwischen zwei aufeinanderfolgenden Werkstücken ("Karossenlücke") umgeschaltet werden kann. Farbwechsel ist ohne Ab-schalten der Hochspannung möglich.The invention comes without the hitherto largely common Zwischenbehältertechnik for color material and avoids their Disadvantage. Et al Can not use unnecessary paint material be conveyed back to the grounded supply device. It is also advantageous that it is possible, but not necessary is the coating material using a Insulating liquid with the mentioned risk of contamination to promote the atomizer. In addition, there is the known Possibility of continuous coating by alternating operation with two parallel lines (A / B operation), between which z. B. in the breaks between two consecutive workpieces ("Body gap") can be switched. Color change is without Switch off the high voltage possible.

Das in Fig. 1 schematisch dargestellte Lackversorgungssystem für einen elektrostatischen Zerstäuber 1 enthält in einem geerdeten Bereich der Beschichtungsanlage eine Baueinheit 2 mit einer ersten Molchstation 3A, die an einen geerdeten Farbwechsler 4 angeschlossen ist, eine im Hochspannungsbereich der Anlage befindliche Baueinheit 6 mit einer zweiten Molchstation 7A, an die der Zerstäuber angeschlossen ist, und zwischen den beiden Molchstationen 3A, 7A eine Leitung 8A aus Isolierwerkstoff , durch die das vom Farbwechsler 4 und der ersten Molchstation 3A kommende Beschichtungsmaterial über die zweite Molchstation 7A dem Zerstäuber 1 zugeführt wird. Die zweite Molchstation kann zeitweise oder dauernd unter Hochspannung stehen. Zwischen dem Farbwechsler 4 und der ersten Molchstation 3A kann eine Messzelle 5 zum Messen des hindurchfließenden Beschichtungsmaterials angeordnet sein.The paint supply system shown schematically in Fig. 1 for an electrostatic atomizer 1 contains in a grounded Area of the coating plant a unit 2 with a first pig station 3A connected to a grounded color changer 4 is connected, one in the high voltage range of the system located unit 6 with a second pig station 7A, to which is connected to the atomizer, and between the two Pig stations 3A, 7A a line 8A made of insulating material, by that of the color changer 4 and the first pig station 3A upcoming coating material via the second pig station 7A the atomizer 1 is supplied. The second pig station can temporarily or permanently under high voltage. Between the Color changer 4 and the first pig station 3A, a measuring cell 5 for measuring the flowing coating material be arranged.

Die isolierende Leitung 8A ist molchbar und kann beispielsweise aus einem Kunststoffschlauch bestehen. Das sich aus Länge und Durchmesser ergebende Leitungsvolumen dieser Leitung entspricht mindestens der für einen Beschichtungsvorgang vorbestimmten Lackvolumenmenge zuzüglich einer Sicherheitslackmenge und zuzüglich des zweifachen zur Potentialtrennung notwendigen Isolierabstands in der Leitung.The insulating line 8A is piggable and may be, for example consist of a plastic tube. That is out of length and Diameter resulting line volume of this line corresponds at least the predetermined for a coating process Paint volume plus a safety paint and plus of the double necessary for electrical isolation separation in the pipe.

Innerhalb der Molchstation 3A können sich die beiden (in Fig. 1 nicht dargestellten) Molche der Leitung 8A in definierten, durch Initiatoren 9A überwachbaren Positionen in einem rohrförmigen Kanal befinden, dessen Ausgang in die isolierende Leitung 8A führt, und in den zwischen den beiden Molchen beispielsweise durch eine Querbohrung und ggf. über ein Ventil die von dem Farbwechsler 4 kommende Farbleitung mündet. Auf der der Leitung 8A abgewandten Seite der beiden Molche kann ferner über ein weiteres Ventil unter Druck stehende Luft als Molchschiebemedium in den Kanal geleitet werden. In der zweiten Molchstation 7A genügt dagegen ein Kanal zur Aufnahme des in Richtung zum Zerstäuber 1 vorderen Molches in einer Position, bei der das in die zweite Molchstation 7A gedrückte Beschichtungsmaterial hinter diesem Molch in eine zu dem Zerstäuber führende Ausgangsleitung 10 fließen kann. Konstruktive Realisierungsmöglichkeiten dieser (nicht dargestellten) Anordnungen stehen einem Fachmann der Molchtechnik zur Verfügung.Within the pig station 3A, the two (in FIG. 1 not shown) pigs of the line 8A in defined, positions monitored by initiators 9A in a tubular Channel, whose output is in the insulating line 8A leads, and in the between the two pigs, for example by a transverse bore and possibly via a valve that of the Color changer 4 coming color line opens. On the line 8A opposite side of the two pigs can also have a another valve pressurized air as a pig pushing medium be channeled into the channel. In the second pig station 7A On the other hand, a channel is sufficient to accommodate the towards the atomizer 1 front pig in a position where the in the second pig station 7A pressed coating material behind this pig in a leading to the atomizer output line 10 can flow. Constructive realization possibilities These arrangements (not shown) are available to a person skilled in the art pig technology available.

Für den hier beschriebenen Zweck geeignete Molche sind an sich bekannt. Insbesondere auf der dem Zerstäuber zugewandten Seite (also als Molch M1 in Fig. 2) kann zweckmäßig ein sog. Kammer- oder Tandemmolch verwendet werden, wie er aus der DE 10033986 bekannt ist. Derartige Molche bestehen aus zwei miteinander verbundenen Teilen, zwischen denen eine Spülflüssigkeit zur Reinigung der Leitungsinnenwand eingefüllt werden kann. Eine wesentliche Eigenschaft der zu verwendenden Molche besteht darin, dass sie bei ihrer Bewegung durch die Leitung 8A an deren Innenwand abgesetztes Farbmaterial rückstandsfrei abstreifen können. Die Molche können jeweils einen Magnet enthalten, so dass ihre Ruhepositionen und ihr Vorbeilauf an definierten Stellen der Leitung 8A durch entsprechende Sensoren oder Initiatoren überwacht und gemeldet werden können. Insbesondere befindet sich ein Molchinitiator 12A am Ende einer an der ersten Molchstation 3A beginnenden Sicherheitsstrecke der Leitung 8A. Diese Sicherheitsstrecke hat eine Länge, die zur Potentialtrennung zwischen dem Hochspannungspotential des Zerstäubers und Erdpotential ausreicht, wenn sie nur Luft enthält. Ein weiterer Molchinitiator 13A dient zur Überwachung einer ähnlichen Sicherheitsstrecke vor der zweiten Molchstation 7A. Für denselben Zweck der Überwachung der Isolierstrecken können auch Lacksensoren vorgesehen sein, die auf das Erscheinen und Vorhandensein der Farblacksäule in der beispielsweise transparenten Leitung 8A ansprechen.For the purpose described here suitable pigs are in themselves known. In particular, on the atomizer side facing (ie as a pig M1 in FIG. 2), a so-called chamber or Tandemmolch be used, as it is known from DE 10033986 is known. Such pigs consist of two together connected parts, between which a rinsing liquid for Cleaning the inner pipe wall can be filled. A essential feature of the newts to be used is that they move along the line 8A at their Wipe off the inner wall of deposited paint material without residue can. The newts can each contain a magnet, so that their rest positions and their passing by are defined Make the line 8A by appropriate sensors or initiators monitored and reported. In particular is located a pig initiator 12A at the end of one at the first Pig station 3A beginning safety route of the line 8A. This safety distance has a length for potential separation between the high voltage potential of the atomizer and Earth potential is sufficient if it contains only air. Another Pig initiator 13A serves to monitor a similar safety route in front of the second pig station 7A. For the same The purpose of the monitoring of the Isolierstrecken can also paint sensors be provided for the appearance and presence the color light column in the example transparent line 8A appeal.

Die darstellungsgemäß in die Ausgangsleitung 10 geschaltete Dosierpumpe 15 zum Dosieren des dem Zerstäuber 1 zugeführten Beschichtungsmaterials soll sich möglichst nahe am Zerstäuber befinden. Eine geeignete Dosiereinrichtung könnte in eine Beschichtungsmaschine oder in den Zerstäuber eingebaut werden. Es kann zweckmäßig und vorteilhaft sein, zumindest auch die zweite Molchstation 7A in die Maschine oder in den Zerstäuber einzubauen, wodurch u.a. Farbverluste auf ein Minimum reduziert werden könnten.The representation according to the output line 10 switched metering pump 15 for dosing the nebulizer 1 supplied coating material should be as close to the atomizer as possible. A suitable metering device could be in a coating machine or installed in the atomizer. It may be appropriate and advantageous, at least the second Install the 7A pigging station in the machine or atomizer whereby i.a. Color losses are reduced to a minimum could.

In manchen Fällen genügt eine einzige zwischen zwei Molchstationen verlaufende Leitung zur Versorgung des Zerstäubers. Durch eine zu der Leitung 8A parallele, gleichartige und in derselben Weise zwischen zwei Molchstationen 3B und 7B geschaltete zweite Leitung 8B lässt sich aber in an sich bekannter Weise ein Versorgungssystem zur quasi kontinuierlichen Lackförderung zu dem Zerstäuber 1 realisieren. Die beiden Leitungen dieses A/B-Systems für jeweils zwei Molche werden einander abwechselnd in der hier beschriebenen Weise verwendet, wobei während des Lackierens aus der einen Leitung mit Hilfe einer den beiden Molchstationen 7A und 7B nachgeschalteten Vorladeanordnung 16 das System zum Lackieren aus der anderen Leitung vorbereitet werden kann. Die Molchstationen der beiden Leitungen können zweckmäßig modular ausgebildet und in der in Fig. 1 angedeuteten Weise zu den Baueinheiten 2 bzw. 6 zusammengefasst sein, ggf. auch mit weiteren modularen Molchstationen für andere Leitungen.In some cases, a single one between two pig stations is sufficient extending line to supply the atomizer. By a parallel to the line 8A, similar and in the same Way connected between two pig stations 3B and 7B second Line 8B can be but in a conventional manner, a supply system for quasi-continuous paint promotion to the Atomizer 1 realize. The two lines of this A / B system for every two pigs are alternately in used as described herein, during painting from the one line with the help of one the two Pig stations 7A and 7B downstream precharge 16 the system prepared for painting from the other line can be. The pig stations of the two lines can expedient modular design and in the direction indicated in Fig. 1 Be summarized way to the units 2 and 6, possibly also with other modular pig stations for other lines.

Das Versorgungssystem ist mit einem Spülsystem verbunden, mit dem die zweite Molchstation 7A (und 7B) unter Hochspannung stehend gespült werden kann. Der daher notwendige isolierende Aufbau der Spülmittelversorgung und aller zugehöriger Rückführungen kann durch Behältertechnik oder Molchpotentialtrennung in an sich bekannter Weise realisiert werden. Bei dem in Fig. 1 dargestellten System wird als Spülmittel dienende Verdünnerflüssigkeit der Baueinheit 6 und ihren Molchstationen 7A, 7B durch die Leitung 20 aus einem im Hochspannungsbereich der Anlage befindlichen Vorratsbehälter 21 zugeführt, der über eine molchbare isolierende Leitung 22 einer zur Potentialtrennung ausreichenden Länge gefüllt werden kann. Die Leitung 22 kann zwischen der hochspannungsseitigen Molchstation 24, an die die zu dem Behälter 21 führende Leitung angeschlossen ist, und beispielsweise einer in der Baueinheit 2 befindlichen Spülmittelquelle 25 mit einer weiteren Molchstation verlaufen. Die Rückführung des die Farbreste enthaltenden verbrauchten Spülmittels aus der Baueinheit 6 kann über die Rückführleitung 26, einen weiteren Zwischenbehälter 27 und eine zwischen zwei weiteren Molchstationen 28 und 29 in den geerdeten Bereich führende Leitung 30 erfolgen. Durch Pulsluftleitungen 32 können die gespülten Bereiche in üblicher Weise getrocknet werden. Je nach der Ausgangsposition der Molche in den Leitungen 22 und 30 können die Versorgungs- und Rückführungsrichtungen des Spülmittels auch umgekehrt werden. Ferner ist es auch denkbar, das verbrauchte Spülmittel innerhalb des Hochspannungsbereichs zu entsorgen, wie durch die gestrichelte Leitung 31 angedeutet ist. The supply system is connected to a flushing system, with the second pig station 7A (and 7B) is under high voltage can be rinsed. The therefore necessary insulating structure the detergent supply and all associated returns can by container technology or pigging potential separation in be realized in a known manner. In the in Fig. 1 The system shown serves as a rinsing agent diluting liquid the unit 6 and its pig stations 7A, 7B through the line 20 from one in the high voltage range of the system supplied reservoir 21, which has a piggable insulating line 22 one for potential separation sufficient length can be filled. The line 22 can between the high-voltage side pig station 24 to which the to the container 21 leading line is connected, and for example a flushing agent source located in the assembly 2 25 run with another pig station. The return of spent paint containing the spent rinse from the assembly 6 can via the return line 26, a another intermediate container 27 and one between two others Pig stations 28 and 29 in the grounded area leading line 30 done. By pulse air lines 32, the rinsed Areas are dried in the usual way. Depending on the Starting position of the pigs in the lines 22 and 30 can the supply and return directions of the detergent also be reversed. Furthermore, it is also conceivable that consumed To dispose of dishwashing liquid within the high voltage range, as indicated by the dashed line 31.

Fig. 2 erläutert in sechs zeitlich aufeinanderfolgenden Verfahrensstufen A) - F) den Prozessablauf bei der Förderung von Beschichtungsmaterial durch eine der isolierenden Leitungen 8 (8A oder 8B) in Fig. 1. Die Pfeile F bedeuten Farbmaterial, während die Pfeile L das Einleiten von Luft bezeichnen.Fig. 2 illustrates in six successive stages of the process A) - F) the process flow in the promotion of coating material through one of the insulating lines 8 (8A or 8B) in Fig. 1. The arrows F mean coloring material while the arrows L indicate the introduction of air.

Beim Ausgangszustand des Systems in der Verfahrensstufe A) befinden sich die beiden Molche M1 und M2 in ihrer Bewegungsrichtung hintereinander in der geerdeten Molchstation 3. Die zu der auf Hochspannung liegenden zweiten Molchstation 7 führende Leitung 8 enthält nur Luft.When the system is in the initial state, go to step A) The two pigs M1 and M2 in their direction of movement one behind the other in the grounded pig station 3. The to the at high voltage lying second pig station 7 leading line 8 contains only air.

In der Verfahrensstufe B) erfolgt das Andrücken der Farbe, d.h. der als Beschichtungsmaterial verwendete Farblack wird in der Molchstation 3 zwischen die beiden Molche geleitet. Durch den Farbdruck wird mit dem Beschichtungsmaterial der erste Molch M1 aus der Molchstation 3 in die Leitung 8 in Richtung zur zweiten Molchstation 7 gedrückt.In process step B), the pressing of the paint, i. the paint used as a coating material is in the Pig station 3 passed between the two pigs. By the Color printing becomes the first pig M1 with the coating material from the pig station 3 in the line 8 in the direction of the second Pig station 7 pressed.

Das Einleiten von Beschichtungsmaterial wird beendet, sobald eine für den Beschichtungsvorgang vorbestimmte Volumenmenge erreicht und in die Leitung 8 eingefüllt ist, spätestens aber bevor die mit Luft gefüllte zwischen dem ersten Molch M1 und der Molchstation 7 verbleibende Leitungsstrecke LS1 die zur elektrischen Isolierung zwischen den beiden Molchstationen notwendige Sicherheitsstrecke (in Fig. 1 zwischen 13A und 7A) unterschreitet. Das Erreichen der vorbestimmten Volumenmenge des Beschichtungsmaterials kann z.B. durch die der Molchstation 3A in der Baueinheit 2 vorgeschaltete Messzelle 5 (Fig. 1) festgestellt werden. Nach Beendigung des Einfüllvorgangs wird der zweite Molch M2 gestartet, indem auf seiner dem ersten Molch M1 abgewandten Rückseite ein isolierendes flüssiges oder gasförmiges Molchschiebemedium, vorzugsweise unter Druck stehende Luft, in die Molchstation 3 geleitet wird. The introduction of coating material is terminated as soon as achieved a predetermined volume for the coating process and is filled in the line 8, but at the latest before the air filled between the first pig M1 and the Pig station 7 remaining line LS1 to electrical Insulation between the two pig stations necessary Safety distance (in Fig. 1 between 13A and 7A) below. Reaching the predetermined volume amount of the coating material can e.g. by the pig station 3A in the measuring unit 2 upstream of the unit 2 (FIG. 1) become. After completion of the filling process of the second pig M2 started by putting on its the first pig M1 reverse side of an insulating liquid or gaseous Pig pushing medium, preferably pressurized air, is conducted to the pig station 3.

In der Stufe C wird die zwischen den beiden Molchen gespeicherte Farbsäule FS von dem mit Druck beaufschlagten Molch M2 durch die Leitung 8 in Richtung zu dem Zerstäuber geschoben. Während hierbei die Luftstrecke LS1 immer kleiner wird, vergrößert sich gleichzeitig im entsprechenden Maße die ebenfalls isolierende Luftstrecke LS2 zwischen der Molchstation 3 und dem Molch M2, so dass weiterhin eine zur Potentialtrennung ausreichende Gesamtluftstrecke (LS1 + LS2) vorhanden bleibt. Die Farbsäule wird von der zweiten Molchstation 7 bei der gegenseitigen Annäherung aufgeladen, sobald die zur Potentialtrennung ausreichende Sicherheitsisolierstrecke im Bereich der Luftstrecke LS1 unterschritten wird.In stage C, the stored between the two pigs Color column FS of the pressurized pig M2 through pushed the line 8 towards the atomizer. While In this case, the air gap LS1 is getting smaller, increases at the same time the correspondingly insulating also Air gap LS2 between the pig station 3 and the pig M2, so that continues to be sufficient for potential separation total air gap (LS1 + LS2) remains. The color column is from the second pig station 7 at the mutual approach charged as soon as the potential isolation is sufficient Safety insulation in the area of the air gap LS1 falls below becomes.

Die Einhaltung der erforderlichen Isolierabstände wird mit Molch- oder Farbsensoren überwacht (12A, 13A in Fig. 1).Compliance with the required Isolierabstände is with Pig or color sensors monitored (12A, 13A in Fig. 1).

Wenn in der Stufe D die Farbsäule FS die zweite Molchstation 7 erreicht hat und sich der Molch M1 in seiner dortigen Endposition befindet, kann das Beschichtungsmaterial in Richtung zum Zerstäuber angedrückt und mit der Beschichtung begonnen werden.If in the D level, the color column FS, the second pig station 7th has reached and the pig M1 in its local end position is located, the coating material in the direction of Atomizer pressed and started with the coating.

Bei der Bemessung der in die Leitung 8 eingefüllten Farbvolumenmenge ist es zweckmäßig, das vorbestimmte Nennvolumen um eine Sicherheitsmenge zu vergrößern. Die nach Beendigung des Beschichtungsvorgangs in der Leitung 8 verbliebene Restmenge kann entweder in Richtung zum Zerstäuber ausgedrückt oder darstellungsgemäß in der Stufe E als Farbpaket FS' zwischen den beiden Molchen M1 und M2 durch die Leitung zurück zu der geerdeten Molchstation 3 geschoben werden, wobei der Molch M1 von in die zweite Molchstation 7 geleitetem isolierenden Schiebemedium, vorzugsweise Luft, beaufschlagt wird.When dimensioning the filled in the line 8 color volume it is expedient, the predetermined nominal volume by one Increase safety quantity. The after completion of the coating process in the line 8 remaining amount can either expressed towards the atomizer or as shown in the stage E as a color packet FS 'between the two Piglets M1 and M2 through the pipe back to the earthed Pig station 3 are pushed, the pig M1 of in the second pig station 7 guided insulating sliding medium, preferably air, is applied.

Wenn der Molch M2 seine Ausgangsposition in der ersten Molchstation 3 erreicht hat, kann in der Stufe F das Farbpaket FS' in an sich bekanntem Reflowbetrieb durch die Molchstation 3 zu der geerdeten Farbversorgungseinrichtung zurückgedrückt werden.When the pig M2 has its starting position in the first pig station 3 has reached, in the level F, the color packet FS ' in per se known reflow operation by the pig station 3 to the grounded ink supply device are pushed back.

Beispielsweise noch vor dem Zurückdrücken der Restfarbmenge können die zweite Molchstation 7 und ggf. der als Molch M2 dienende Tandemmolch mit in die zweite Molchstation 7 geleiteter Spülflüssigkeit gespült werden. Die erste Molchstation 3 wird zweckmäßig mit in diese Station geleiteter Spülflüssigkeit gespült, sobald der erwähnte Reflowbetrieb beendet ist.For example, even before pushing back the residual amount of paint can the second pig station 7 and possibly serving as a pig M2 Tandemmolch headed into the second pig station 7 Rinsing fluid are rinsed. The first pig station 3 will be expediently flushed with flushing liquid conducted into this station, as soon as the mentioned reflow operation is finished.

Zur Förderung des Farbmaterials durch die die beiden Molchstationen verbindende Leitung (8A bzw. 8B) können auch jeweils mehr als nur zwei Molche sinnvoll verwendet werden. Beispielsweise kann es zweckmäßig sein, ausgehend von vier hintereinander in der ersten Molchstation geparkten Molchen zwischen die ersten beiden Molche ein Löse- und/oder Schmiermedium (z.B. Verdünnerflüssigkeit), zwischen den zweiten und den dritten Molch das durch die Leitung zu fördernde Farbmaterial und zwischen den dritten und den vierten Molch erneut Löse- und/oder Schmiermedium zu leiten, wobei zur Potentialtrennung in der oben beschriebenen Weise Luftisolierstrecken auf den dem Molchpaket abgewandten Seiten des ersten und des vierten Molches gebildet werden.To promote the color material through the two pig stations connecting line (8A and 8B) can also each more than just two newts are usefully used. For example it may be appropriate, starting from four in a row piggybacks parked in the first pig station between the first two pigs are a solvent and / or lubricating medium (e.g. Thinner liquid), between the second and the third Pig the color material to be conveyed through the pipe and between the third and the fourth pig again Löse- and / or To conduct lubricating medium, wherein the potential separation in the above described way Luftisolierstrecken on the pig package opposite sides of the first and the fourth pig formed become.
