Diese Aufgabe wird durch die Gegenstände der unabhängigen Ansprüche gelöstThis object is solved by the subject matters of the independent claims

Bevorzugte Ausführungsformen der Erfindung sind in den Unteransprüchen beschrieben.Preferred embodiments of the invention are described in the subclaims.

Die vorliegende Erfindung umfasst die Erkenntnis, dass die aus dem Stand der Technik bekannten Düsenverschlüsse und Verfahren, insbesondere die aus dem Stand derThe present invention encompasses the recognition that the nozzle closures and methods known from the prior art, in particular those known from the prior art

Technik bekannten Düsenverschlüsse und Verfahren zum Verschließen einer Düse zur Abgabe von Material für eine Flüssigfolie, zur Bildung von so genannten Multistrahldüsen zumeist Grundplatten mit mehreren Durchgangslöchern aufweisen. Bei diesen Multistrahldüsen wird dann mit Hilfe eines einen Dichtungsring tragenden Stempels der Materialfluß der Flüssigfolie durch die mehreren Durchgangslöcher in der Grundplatte beendet, in dem der im geöffneten Zustand zur Abgabe des Materials für die Flüssigfolie in einem Abstand zur Grundplatte positionierte Stempel auf die Grundplatte zubewegt wird, bis der Dichtungsring die Anordnung der die Multistrahldüse bildenden Durchgangslöcher In der Grundplatte gegenüber der Zufuhr von Flüssigfolienmaterial abdichtet.Technik known nozzle seals and methods for closing a nozzle for dispensing material for a liquid film, to form so-called multi-jet nozzles mostly base plates having a plurality of through holes. In these multi-jet nozzles, the material flow of the liquid film is then terminated by the plurality of through holes in the base plate by means of a seal ring bearing seal, in which the die positioned in the open state for discharging the material for the liquid foil at a distance from the base plate is moved toward the base plate until the sealing ring seals the arrangement of the multi-jet nozzle-forming through holes in the base plate against the supply of liquid foil material.

Im Zusammenhang mit den vorstehend beschriebenen bekannten Düsenverschlüssen bzw. Verfahren zum Verschließen von Düsen hat die vorliegende Erfindung weiterhin erkannt, dass der verwendete Dichtring kompressibel sein muss, um sicher zu dichten, um somit zuverlässig und vor allen Dingen auch schnell eine Materialzufuhr der Flüssigfolie zu den Durchgangslöchern der in der Grundplatte ausgelittenen Multistrahldüse zu stoppen. Denn derartige Multistrahldüsen zum Auftragen von Flüssigfolie werden heutzutage beispielsweise beim Schützen von Lacken von Neuwagen in der Automobilindustrie verwendet. Bei derartigen Verwendungen wird die Multistrahldüse an extrem schnell beweglichen Roboterarmen über den Lack des Automobils geführt und muss durch die hohe Bewegungsgeschwindigkeit des Roboterarms relative zur Lackoberfläche des Automobils in der Lage sein, innerhalb von weniger als 10 ms eine Abgabe von Flüssigfolie zu stoppen. Dabei hat nun die vorliegende Erfindung noch weiter erkannt, dass der den Dichtring um die Durchgangslöcher in der Grundplatte andrückende Stempel die Dichtung für ein sicheres Abdichten nicht nur an die Grundplatten anlegen, sondern vielmehr diese Dichtung mit relativ großem Druck auf die Grundplatte aufdrücken muss. Dabei hat die Erfindung weiter erkannt, dass es dabei zu einer Kompression des Dichtringes kommt und hiermit wiederum zu einer Verringerung des Volumens des zwischen stempelseitiger Oberfläche der Grundplatte, Dichtring und dem den Dichtring tragenden Stempel gebildeten Hohlraums kommt. Dies hat jedoch nach Erkenntnissen der vorliegenden Erfindung letztlich zur Folge, dass es zu einem unerwünschten Nachtropfen von Flüssigfolienmaterial aus den Durchgangslöchern der Grundplatte der Multistrahldüse kommt.In connection with the known nozzle closures described above, the present invention has further recognized that the sealing ring used must be compressible in order to securely seal in order to reliably and, above all, rapidly feed the liquid foil to the nozzle To stop through holes in the base plate suffered multi-jet nozzle. Because such multi-jet nozzles for applying liquid film are used today, for example, in the protection of paints of new cars in the automotive industry. In such applications, the multi-jet nozzle is guided over the paint of the automobile on extremely fast moving robot arms, and due to the high moving speed of the robot arm relative to the paint surface of the automobile must be able to stop dispensing liquid film in less than 10 ms. In this case, the present invention has further recognized that the stamp pressing the sealing ring around the through holes in the base plate not only apply the seal for a secure seal to the base plates, but rather must press this seal with a relatively large pressure on the base plate. In this case, the invention has further recognized that it comes to a compression of the sealing ring and hereby again leads to a reduction in the volume of the stamp-side surface of the base plate, sealing ring and the sealing ring bearing punch formed cavity. However, according to findings of the present invention, this ultimately results in undesirable dripping of liquid foil material from the through holes of the base plate of the multi-jet nozzle.

Weiterhin umfasst die Erfindung auch die Erkenntnis, dass die vorstehend beschriebenen, aus dem Stand der Technik bekannten Dichtungen zumeist aus Polyurethan bestehen, welches bei den zuvor beschriebenen harten Anforderungen verschteißanfällig ist und innerhalb von wenigen Tagen ermüdet. Dies bedeutet, dass der Stempel mit einem noch höheren Anpreßdruck die Dichtung an die Materialzufuhrseite der Grundplatte anpressen muss, was wiederum den zuvor beschriebenen Nachtropfeffekt erhöht, da das Volumen zwischen Materialzufuhrseite der Grundplatte, Dichtung und Stempel dann noch weiter verringert wird.Furthermore, the invention also encompasses the recognition that the seals described above, known from the prior art, mostly consist of polyurethane, which is susceptible to splitting in the hard requirements described above and fatigues within a few days. This means that the stamp with a even higher contact pressure must press the seal to the material supply side of the base plate, which in turn increases the dripping effect described above, since the volume between the material supply side of the base plate, seal and stamp is then further reduced.

Die Gegenstände der unabhängigen Ansprüche überwinden die vorstehend beschriebenen Probleme und Nachteile des Standes der Technik.The subject matters of the independent claims overcome the problems and disadvantages of the prior art described above.

Bei einer bevorzugten Auführungsform der Erfindung wird im geöffneten Zustand der Verbindung zwischen Materialzufuhr und Durchgangsloch die Verbindung aus mindestens einem Durchgangsloch und mindestens einem ersten Kanal gebildet.In a preferred embodiment of the invention, in the opened state of the connection between the material supply and the through-hole, the connection is formed from at least one through-hole and at least one first channel.

Bei der Erfindung weist die Deckplatte mindestens einen zweiten Kanal zum Verbinden einer Spülftüssigkeitzufuhr der Deckplatte mit einer der Grundplatte zugewandten Seite der Deckplatte auf. Auf diese Weise kann mittels der Erfindung nicht nur das mindestens eine Durchgangsloch durch die Verschiebebewegung von Grundplatte und Deckplatte relativ zueinander geöffnet und verschlossen werden, sondern, bevorzugt gleichzeitig, ein zweiter Kanal zum Zuführen von, bevorzugt Wasser enthaltenden, Spülmittel zum Reingen des mindestens einen Durchgangsloches in der Grundplatte geöffnet werden. Dieses Öffnen einer Verbindung von Spolmittetzuführ mit einer der Grundplatte zugewandten Seite der Deckplatte, bevorzugt an einer mit einem Durchgangsloch der Grundplatte fluchtenden Stelle, geschieht gleichzeitig mit dem Schließen der Verbindung von Materialzufuhr mit einem Durchgangsloch der Grundplatte. Mit anderen Worten wird bei der Erfindung eine Verschiebung von Grund- und Deckplatte gegeneinander derart vorgenommen, dass bei geöffneter Verbindung mit der Materialzufuhr die Spülmittelzufuhr geschlossen ist und umgekehrt. So ist das Verschieben von Grund- und Deckplatte derart ausgebildet, dass in einer ersten Position von Grund- und Deckplatte relativ zueinander die Materialzufuhr mit dem mindestens einen Durchgangsloch der Grundplatte verbunden ist und in einer zweiten Position von Grund- und Deckplatte zueinander die Spülmittelzufuhr mit dem mindestens einen Durchgangsloch der Grundplatte verbunden istIn the invention, the cover plate has at least one second channel for connecting a Spülftüssigkeitzufuhr the cover plate with a base plate side facing the cover plate. In this way, not only the at least one through hole can be opened and closed relative to each other by the sliding movement of the base plate and cover plate, but also, preferably simultaneously, a second channel for supplying, preferably water-containing, rinsing agent for ringing the at least one through hole be opened in the base plate. This opening of a connection of Spolmittetzuführ with one of the base plate side facing the cover plate, preferably on a aligned with a through hole of the base point occurs simultaneously with the closing of the connection of material supply with a through hole of the base plate. In other words, in the invention, a displacement of the base and cover plate against each other is made such that when opened connection with the supply of material, the detergent supply is closed and vice versa. Thus, the displacement of the base and cover plate is formed such that in a first position of the base and cover plate relative to each other, the material supply is connected to the at least one through hole of the base plate and in a second position of the base and cover plate to each other, the detergent supply to the at least one through hole of the base plate is connected

Bei der Erfindung weist die Grundplatte mindestens zwei Durchgangslocher auf, wobei Grund- und Deckplatte im Wesentlichen lateral zu einer Verbindungslinie zwischen den mindestens zwei Durchgangslöchem gegeneinander verschiebbar sind. Hierdurch ist eine besonders einfache Ausgestaltung der Erfindung möglich.In the invention, the base plate has at least two through holes, wherein the base and cover plate substantially laterally to a connecting line between the at least two Durchgangslöchem are mutually displaceable. As a result, a particularly simple embodiment of the invention is possible.

Bei einer alternativen Ausführungsform, bei der die Grundplatte mindestens zwei Durchgangslöcher aufweist, sind Grund- und Deckplatte im Wesentlichen parallel zu einer Verbindungslinie zwischen mindestens zwei Durchgangslöchern gegeneinander verschiebbar. Diese Ausführungsform bietet sich insbesondere bei beengten Platzverhältnissen an, die die oben genannte Lateralverschiebung nicht zulassen.In an alternative embodiment in which the base plate has at least two through-holes, the base and cover plates are displaceable relative to each other substantially parallel to a connecting line between at least two through-holes. This embodiment is particularly suitable in confined spaces that do not allow the above-mentioned lateral displacement.

Bevorzugt ist die Gesamtzahl von ersten und zweiten Kanälen in der Deckplatte mindestens doppelt so groß wie die Anzahl von Durchgangslöchern in der Grundplatte. Auf diese Weise kann jedem Durchgangsloch beispielsweise ein Kanal für die Materialzufuhr und ein Kanal für die Spülmittelzufuhr zur Verfügung gestellt werden.Preferably, the total number of first and second channels in the cover plate is at least twice as large as the number of through holes in the base plate. In this way, for example, a passage for the supply of material and a channel for the supply of detergent can be made available to each through-hole.

Bei einer weiteren bevorzugten Ausführungsform ist eine der Grundplatte zugewandte Öffnung des zweiten Kanals der Deckplatte schlitzartig ausgebildet. Auf diese Weise läßt sich der zweite Kanal für die Spülmiltelzufuhr besonders einfach und kostengünstig herstellen.In a further preferred embodiment, one of the base plate facing opening of the second channel of the cover plate is formed like a slit. In this way, the second channel for the Spülmiltelzufuhr can be particularly simple and inexpensive to produce.

Bevorzugt sind Ausführungsformen, bei denen eine der Grundplatte zugewandte Öffnung des mindestens einen ersten Kanals der Deckplatte mit einer der Deckplatte zugewandten Öffnung des mindestens einen Durchgangsloches der Grundplatte im Wesentlichen fluchtet. Auf diese Weise wird im geöffneten Zustand, d.h. bei hergestellter Verbindung zwischen der Materialabgabeseite der Grundplatte mit der Materialzufuhr eine optimale Strömung für die Flüssigfolie zur Verfügung gestellt, um möglichst Verstopfungen der so ausgebildeten Düse zu verhindern.Embodiments in which an opening of the at least one first channel of the cover plate facing the base plate is substantially aligned with an opening of the at least one through hole of the base plate facing the cover plate are preferred. In this way, in the open state, i. made at the established connection between the material discharge side of the base plate with the material supply an optimal flow for the liquid film provided to prevent possible obstruction of the thus formed nozzle.

Auf diese Weise ist eine hohe Geschwindigkeit beim Verschließen der Düse und gleichzeitig eine hohe Verschleißfestigkeit der aufeinander gleitenden Fläche und somit eine hohe Wartungsfreiheit der Vorrichtung gewährleistet. Dabei ist besonders bevorzugt, wenn zumindest die - beim Verschieben von Grund- und Deckplatte gegeneinander - aufeinander gleitenden Flächen von Grund- und Deckplatte im Wesentlichen aus dem gleichen Material, bevorzugt aus Edelstahl, bestehen.In preferred embodiments of the invention, sliding surfaces of the base plate facing side of the cover plate or the cover plate facing side of the base plate, when the base and cover plate are moved against each other, are formed substantially completely flat.

It is particularly preferred if at least the - when moving the base and cover plate against each other - successive sliding surfaces of the base and cover plate substantially of the same material, preferably made of stainless steel.

Bei dem erfindungsgemäßen Verfahren ist es besonders bevorzugt, wenn Grund- und Deckplatte im Wesentlichen senkrecht zu einer Fließrichtung des Materials in der Grundplatte verschoben werden.In the method according to the invention it is particularly preferred if the base and cover plate are displaced substantially perpendicular to a flow direction of the material in the base plate.
