Definitions
- the invention relates to a nozzle device for dispensing a viscous, in particular highly viscous, application medium in the form of at least one jet or at least two jets onto a component, preferably for the surrounding application of the application medium to a fold, an edge or a transition seam of the component.

- a robot program is usually created in such a way that the lower edge of the spray jet emitted from the nozzle is applied a few millimeters below the standing seam and thus past the standing seam ("shot past") becomes.

Das Bauteil ist vorzugsweise ein Kraftfahrzeugbauteil (z. B. ein Kraftfahrzeugkarosseriebauteil), kann aber auch z. B. ein Bauteil eines Nutzfahrzeugs (z. B. ein Nutzfahrzeugkarosseriebauteil, ein Bauteil eines Luftfahrzeugs, ein Fenster (z. B. eine Fensterscheibe) oder ein Fassadenbauteil sein.The invention relates to a nozzle device for dispensing a viscous, in particular highly viscous, application medium in the form of at least one jet or at least two jets onto a component, preferably for the surrounding application of the application medium to a fold, an edge or a transition seam of the component. The component is preferably a motor vehicle component (e.g. a motor vehicle body component), but can also be e.g. B. a component of a commercial vehicle (e.g. a commercial vehicle body component, a component of an aircraft, a window (e.g. a window pane) or a facade component.
Zum allgemeinen Stand der Technik wird auf die
Die Anforderungen an eine konventionelle PVC-Naht liegen bei üblicherweise 15 mm bis 25 mm Nahtbreite und 1,5 mm bis 2,5 mm Nahthöhe. Damit dies mit einer baulich begrenzten Düse realisiert werden kann, wird die Schlitzöffnung der konventionellen Flachstrahldüse konvex ausgeprägt, so dass sich die Strahlbreite des Spritzstrahls zum Stehfalz und somit zur Abgabeseite hin vergrößert.The requirements for a conventional PVC seam are usually 15 mm to 25 mm seam width and 1.5 mm to 2.5 mm seam height. So that this can be achieved with a structurally limited nozzle, the slot opening of the conventional flat jet nozzle is convex so that the jet width of the spray jet increases towards the standing seam and thus towards the delivery side.
Nachteilig bei dem zuvor beschriebenen Stand der Technik ist insbesondere, dass ein Teil des abgegebenen PVC-Materials prozessbedingt an dem Stehfalz "vorbeigeschossen" wird. Das hat zur Folge, dass der die Flachstrahldüse führende Roboter und/oder die Applikationszelle, in der das Verfahren ausgeführt wird, verschmutzt wird, und somit ein erhöhter Reinigungsaufwand entsteht. Die Applikation lässt sich aufgrund von Bauteiltoleranzen, die üblicherweise bei KraftfahrzeugKarosserien vorliegen, meist nicht anders einstellen. Die Bauteiltoleranzen führen auch dazu, dass der Stehfalz meist von beiden Seiten appliziert werden muss. Gefügte Blechkanten z. B. unterscheiden sich in ihrer Länge von Karosserie zu Karosserie.A particular disadvantage of the prior art described above is that part of the released PVC material is "shot past" the standing seam as a result of the process. This has the consequence that the robot guiding the flat jet nozzle and / or the application cell in which the method is carried out is soiled, and thus an increased cleaning effort arises. The application can usually not be set differently due to component tolerances that are usually found in motor vehicle bodies. The component tolerances also mean that the standing seam usually has to be applied from both sides. Joined sheet metal edges z. B. differ in length from body to body.

Die unter Bezugnahme auf die Figuren beschriebenen Ausführungsformen der Erfindung stimmen teilweise überein, wobei ähnliche oder identische Teile mit den gleichen Bezugszeichen versehen sind, und zu deren Erläuterung auch auf die Beschreibung anderer Ausführungsformen oder Figuren verwiesen wird, um Wiederholungen zu vermeiden.The embodiments of the invention described with reference to the figures are partially identical, with similar or identical parts being provided with the same reference symbols, and for their explanation also to the description Reference is made to other embodiments or figures in order to avoid repetition.
Die Düsenvorrichtung 1 wird nachfolgend unter gemeinsamer Bezugnahme auf die
Die Düsenvorrichtung 1 dient zur Abgabe eines viskosen Auftragsmediums (z. B. PVC-Material; PVC: Polyvinylchlorid) in Form eines Strahls S1 auf ein Bauteil, insbesondere ein Kraftfahrzeugbauteil (z. B. einen Falz, eine Kante oder eine Übergangsnaht des Kraftfahrzeugbauteils). Das Kraftfahrzeugbauteil ist vorzugsweise eine Kraftfahrzeugkarosserie. Die Düsenvorrichtung 1 ist als Düsenkopf ausgeführt, wobei der Düsenkopf vorzugsweise ein einstückig-integrales Bauteil darstellt und somit aus einem einzigen Stück gefertigt sein kann.The
Der Strahl S1 ist ein Flachstrahl und definiert eine Strahlbreite B1, B2, die sich relativ zur Abgaberichtung P des Auftragsmediums zweckmäßig verändert.The jet S1 is a flat jet and defines a jet width B1, B2, which expediently changes relative to the delivery direction P of the application medium.
Die Düsenvorrichtung 1 weist eine Öffnungskonfiguration 2 zur Ausbildung einer Schlitzöffnung 3.1 auf, mittels der das Auftragsmedium abgegeben wird. Die Öffnungskonfiguration 2 wird abgabeseitig durch eine Abspritzkantenstruktur 2.1, 2.2, 2.3, 2.4 definiert.The
Die Öffnungskonfiguration 2 und somit die Schlitzöffnung 3.1 sind zweckmäßig gekrümmt konkav ausgeformt und sind während der Abgabe des Auftragsmediums auf das Kraftfahrzeugbauteil im Wesentlichen stirnseitig zum Kraftfahrzeugbauteil ausgerichtet.The
Dadurch, dass die Öffnungskonfiguration 2 und somit die Schlitzöffnung 3.1 konkav ausgeformt sind, wird eine Verschmälerung der Strahlbreite B1, B2 zur Abgabeseite A hin bewirkt, so dass sich die Strahlbreite B1, B2 relativ zur Abgaberichtung P des Auftragsmediums verkleinert. Die Strahlbreite B2 ist demnach kleiner als die Strahlbreite B1.Because the
Die Öffnungskonfiguration 2 definiert eine Strahlebene für den Strahl S1, innerhalb derer sich der Strahl S1 erstreckt und innerhalb derer sich die Strahlbreite B1, B2 zur Abgabeseite A hin verschmälert.The
Durch die Verschmälerung der Strahlbreite B1, B2 kann der Strahl S1 derart gebündelt werden, dass er beim Auftreffen auf das Kraftfahrzeugbauteil dieses umschließt (umgreift), so dass das Auftragsmedium in vorteilhafter Weise nicht am Kraftfahrzeugbauteil vorbeiappliziert werden muss und dennoch auf zwei Seitenflächen des Kraftfahrzeugbauteil und vorzugsweise dessen Stirnfläche treffen kann.By narrowing the beam width B1, B2, the beam S1 can be bundled in such a way that when it strikes the motor vehicle component, it encloses (surrounds) it, so that the application medium advantageously does not have to be applied past the motor vehicle component and yet on two side surfaces of the motor vehicle component and can preferably meet its end face.
Besonders vorteilhaft kann der Strahl S1 durch die Verschmälerung der Strahlbreite B1, B2 derart gebündelt werden, dass er zur z. B. 3-seitig umschließenden Applikation des Auftragsmediums auf einen Falz, eine Kante oder eine Übergangsnaht des Kraftfahrzeugbauteils genutzt werden kann.The beam S1 can particularly advantageously be bundled by narrowing the beam width B1, B2 in such a way that it is directed towards z. B. 3-sided enclosing application of the application medium on a fold, an edge or a transition seam of the motor vehicle component can be used.
Die Öffnungskonfiguration 2 ist relativ zu einem Längsschnitt A-A entlang der Öffnungskonfiguration 2 konkav ausgeformt und in einer konkav ausgeformten Stirnseite 4 der Düsenvorrichtung 1 ausgebildet. Die Öffnungskonfiguration 2 und somit die Schlitzöffnung 3.1 sind über zumindest nahezu ihre gesamte Längserstreckung L konkav ausgeformt.The
In die Düsenvorrichtung 1 ist eine Materialaussparung 5, 6 zur Zufuhr des Auftragsmediums zu der Öffnungskonfiguration 2 und somit zu der Schlitzöffnung 3.1 eingearbeitet.A
Die Materialaussparung 5, 6 umfasst einen Leitungsabschnitt 5 und einen stromabwärts des Leitungsabschnitts 5 angeordneten Kammerabschnitt 6, wobei der Durchlassquerschnitt des Kammerabschnitts 6 größer ist als der Durchlassquerschnitt des Leitungsabschnitts 5. Der Durchlassquerschnitt des Leitungsabschnitts 5 kann z. B. rund ausgeformt sein (zweckmäßig mittels Bohrung) und der Durchlassquerschnitt des Kammerabschnitts 6 kann im Wesentlichen flach und schlitzförmig ausgebildet sein.The
Die Materialaussparung 5, 6, insbesondere der Kammerabschnitt 6, mündet in der Öffnungskonfiguration 2 und bildet abgabeseitig die Öffnungskonfiguration 2 und somit die Schlitzöffnung 3.1.The

Die Öffnungskonfiguration 2 und somit die Schlitzöffnung 3.1 sind während der Abgabe des Auftragsmediums im Wesentlichen stirnseitig zum Stehfalz ausgerichtet.The
Dadurch, dass die Öffnungskonfiguration 2 eine Verschmälerung der Strahlbreite B1, B2 zur Abgabeseite A hin bewirkt, trifft der Strahl S1 auf die Stirnfläche, aber auch auf die zwei Seitenflächen des Stehfalzes.Because the
Die Öffnungskonfiguration 2 ermöglicht somit eine insbesondere 3-seitig umschließende Applikation des Auftragsmediums auf den Stehfalz.The
Die Düsenvorrichtung 1 der
Eine Besonderheit ist aber, dass beidseitig außen neben der Öffnungskonfiguration 2 eine abstehende Hornstruktur 7.1, 7.2 angeordnet ist und die Hornstruktur 7.1, 7.2 zumindest zwei einwärts geformte Innenflanken 8.1, 8.2 umfasst.A special feature, however, is that a protruding horn structure 7.1, 7.2 is arranged on both sides outside next to the
Die Innenflanken 8.1, 8.2 wirken so auf das aus der Schlitzöffnung 3.1 ausgegebene Auftragsmedium, dass die Verschmälerung der Strahlbreite B1, B2 unterstützt und das Auftragsmedium einwärts umgelenkt wird.The inner flanks 8.1, 8.2 act on the application medium dispensed from the slot opening 3.1 in such a way that the narrowing the beam width B1, B2 is supported and the application medium is deflected inward.

Die Öffnungskonfiguration 2 ist zweckmäßig konkav ausgeformt, um eine Verschmälerung der Strahlbreite B1, B2 zur Abgabeseite A hin zu bewirken.The
Der Strahl S1 kann hierbei z. B. wie in den
Eine Besonderheit der Düsenvorrichtung 10 ist aber, dass die Düsenvorrichtung 10 nicht als einstückig-integraler Düsenkopf ausgebildet ist, sondern als Düsenplatte, mit einer neben der Düsenplatte anzuordnenden Gegenplatte 13. Die Düsenvorrichtung 10 und die Gegenplatte 13 sind zwischen den zwei Klemmteilen der Plattenhalterung 11 angeordnet, um dadurch gehalten und fixiert zu werden. Eine Fixierung 12 dient dazu, die zwei Klemmteile der Plattenhalterung 11 und somit die die Düsenvorrichtung 10 und die Gegenplatte 13 zu verklemmen.A special feature of the
Die Gegenplatte 13 ist abgabeseitig komplementär konkav ausgeformt zur Öffnungskonfiguration 2 und dient dazu, die Öffnungskonfiguration 2 und somit die Schlitzöffnung 3.1 sowie die Materialaussparung 5, 6 in Umfangsrichtung zu schließen.The counter-plate 13 is concave on the delivery side in a complementary manner to the
Die Düsenvorrichtung 10 kann optional die Hornstruktur 7,1, 7.2 umfassen.The
Ebenfalls optional kann die Materialaussparung 5, 6 beidseitig Innenflanken F1, F2 aufweisen, um das Abgabemedium einwärts zu der Schlitzöffnung 3.1 umzulenken.The
Eine Besonderheit ist aber, dass die Öffnungskonfiguration 2 der Düsenvorrichtung 10 der
Die zwei Strahlen S1, S2 definieren eine die zwei Strahlen S1, S2 umfassende Strahlbreite B1, B2.The two beams S1, S2 define a beam width B1, B2 comprising the two beams S1, S2.
Die Öffnungskonfiguration 2 ist konkav ausgeformt, so dass eine Verschmälerung der die zwei Strahlen S1, S2 umfassenden Strahlbreite B1, B2 zur Abgabeseite A hin bewirkt wird. Die Öffnungen 3.1, 3.2 sind durch die konkave Öffnungskonfiguration 2 einwärts ausgerichtet, so dass sich die Strahlen S1, S2 zur Abgabeseite A hin einander annähern.The
Zur Bildung oder Separierung der zwei Schlitzöffnungen 3.1, 3.2 umfasst die Öffnungskonfiguration 2 einen Teilungsabschnitt T.To form or separate the two slot openings 3.1, 3.2, the

Ähnlich wie bei den anderen Düsenvorrichtungen 1 und 10 kann auch bei dieser Ausführungsform eine Verschmälerung der Strahlbreite B1, B2 zur Abgabeseite A hin bewirkt werden.Similar to the

B. ein Falz, eine Kante oder eine Übergangsnaht, im Wesentlichen stirnseitig zueinander ausgerichtet. Dennoch trifft durch die Verschmälerung der Strahlbreite B1, B2 zur Abgabeseite A hin das Auftragsmedium auf zwei Seitenflächen 101, 102 und eine Stirnfläche 103 des Kraftfahrzeugbauteils 100.During the delivery of the application medium, the
