Definitions

  • the invention relates to a nozzle device according to one of claims 1 to 18 and a method according to one of claims 19 or 20 for dispensing a preferably viscous, in particular highly viscous, dispensing medium onto a component, preferably for dispensing the dispensing medium onto two side faces and optionally one end face of a fold ( e.g. standing seam), 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.
  • standing seams (z. B. component edges), as z. B. occur in the sill area or on the side members of a motor vehicle, sealed by means of conventional, robot-guided flat jet nozzles (also called flat stream nozzles) made of hard metal.
  • the standing seam is sealed with PVC (PVC: polyvinyl chloride) from at least one and possibly also from both sides.
  • PVC polyvinyl chloride
  • a robot program is usually created in such a way that the lower edge of the spray jet emitted from the nozzle passes a few millimeters below the standing seam and thus on the standing seam is applied over (“missed").
  • the PVC material that is applied to one side of the standing seam wraps itself around the seam edge to a certain extent and thus seals the lower, corrosion-prone side of the standing seam.
  • 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.
  • 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.

Unter Bezugnahme auf Figur 10 werden gemäß Stand der Technik insbesondere Stehfalze (z. B. Bauteilkanten), wie sie z. B. im Schwellerbereich oder an Längsträgern eines Kraftfahrzeugs vorkommen, mittels konventionellen, robotergeführten Flachstrahldüsen (auch Flatstreamdüsen genannt) aus Hartmetall abgedichtet. Bei diesem Verfahren wird der Stehfalz von mindestens einer und eventuell auch von beiden Seiten mit PVC (PVC: Polyvinylchlorid) abgedichtet. Damit auch die Unterseite des Stehfalzes prozesssicher abgedichtet werden kann, wird ein Roboterprogramm üblicherweise so erstellt, dass die untere Kante des aus der Düse ausgebrachten Spritzstrahles einige Millimeter unter dem Stehfalz hindurch und somit an dem Stehfalz vorbeiappliziert ("vorbeigeschossen") wird. Das PVC-Material, das auf eine Seite des Stehfalzes aufgetragen wird, legt sich zu gewissen Teilen um die Falzkante und dichtet so die untere korrosionsanfällige Seite des Stehfalzes ab.With reference to Figure 10 are according to the prior art in particular standing seams (z. B. component edges), as z. B. occur in the sill area or on the side members of a motor vehicle, sealed by means of conventional, robot-guided flat jet nozzles (also called flat stream nozzles) made of hard metal. In this process, the standing seam is sealed with PVC (PVC: polyvinyl chloride) from at least one and possibly also from both sides. So that the underside of the standing seam can also be reliably sealed, a robot program is usually created in such a way that the lower edge of the spray jet emitted from the nozzle passes a few millimeters below the standing seam and thus on the standing seam is applied over ("missed"). The PVC material that is applied to one side of the standing seam wraps itself around the seam edge to a certain extent and thus seals the lower, corrosion-prone side of the standing seam.

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 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 has to be applied from both sides. Joined sheet metal edges z. B. differ in length from body to body.

Eine Aufgabe der Erfindung ist es, eine Möglichkeit zur Abgabe eines z. B. viskosen Abgabemediums auf zumindest zwei Seitenflächen eines Bauteils, vorzugsweise z. B. einen Falz, eine Kante oder eine Übergangsnaht des Bauteils, zu schaffen, mittels der die erforderliche Menge des Abgabemediums reduziert werden kann.An object of the invention is to provide a way to deliver a z. B. viscous release medium on at least two side surfaces of a component, preferably z.

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 partially match, similar or identical parts being provided with the same reference symbols, and for their explanation reference is also made to the description of other embodiments or figures in order to avoid repetition.

Figur 1 zeigt eine Seitenansicht einer als Düsenplatte ausgebildeten Düsenvorrichtung 1 mit einer Gegenplatte 20 gemäß einer Ausführungsform der Erfindung, wobei Figur 2 eine zugehörige Längsschnittansicht entlang Linie A-A der Figur 1 zeigt und Figur 3 eine Schnittansicht der Gegenplatte 20 zeigt. Figure 1 shows a side view of a nozzle device 1 designed as a nozzle plate with a counter plate 20 according to an embodiment of the invention, wherein Figure 2 an associated longitudinal sectional view along line AA of the Figure 1 shows and Figure 3 a sectional view of the counter plate 20 shows.

Die Düsenvorrichtung 1 und die Gegenplatte 20 werden nachfolgend unter gemeinsamer Bezugnahme auf die Figuren 1 bis 3 beschrieben.The nozzle device 1 and the counter plate 20 will be described below with common reference to FIG Figures 1 to 3 described.

Die Düsenvorrichtung 1 dient zur Abgabe eines viskosen oder hochviskosen Abgabemediums (z. B. PVC) auf ein Bauteil 100, vorzugsweise Kraftfahrzeugbauteil 100, vorzugsweise zur Abgabe des Abgabemediums auf zwei Seitenflächen 101, 102 und optional eine Stirnfläche 103 eines Falzes, einer Kante oder einer Übergangsnaht des Kraftfahrzeugbauteils 100.The nozzle device 1 is used to deliver a viscous or highly viscous delivery medium (e.g. PVC) onto a component 100, preferably a motor vehicle component 100, preferably to deliver the delivery medium onto two side surfaces 101, 102 and optionally an end surface 103 of a fold, an edge or one Transition seam of the motor vehicle component 100.

Die Düsenvorrichtung 1 umfasst eine Öffnungskonfiguration zur Abgabe des Abgabemediums. Die Öffnungskonfiguration weist zwei Öffnungen 2.1, 2.2 zur Ausgabe von zwei Strahlen S1, S2 des Abgabemediums auf. Die Öffnungen 2.1, 2.2 sind vorzugsweise als Schlitzöffnungen zur Abgabe von Flachstrahlen ausgeführt, können aber auch z. B. konkav oder konvex ausgebildet sein.The nozzle device 1 comprises an opening configuration for dispensing the dispensing medium. The opening configuration has two openings 2.1, 2.2 for the output of two jets S1, S2 of the delivery medium. The openings 2.1, 2.2 are preferably designed as slot openings for the delivery of flat jets, but can also, for. B. be concave or convex.

Die zwei Öffnungen 2.1, 2.2 sind in derselben Ebene einwärts ausgerichtet, so dass die zwei Strahlen S1, S2 sich zur Abgabeseite A hin einander annähern.The two openings 2.1, 2.2 are aligned inwards in the same plane, so that the two beams S1, S2 approach one another towards the delivery side A.

Während der Abgabe des Auftragsmediums sind die Düsenvorrichtung 1 und das Kraftfahrzeugbauteil 100, insbesondere z. B. ein Falz, eine Kante oder eine Übergangsnaht des Kraftfahrzeugbauteils 100, im Wesentlichen stirnseitig zueinander ausgerichtet. Dennoch trifft durch die zwei einwärts gerichteten Strahlen S1, S2 das Abgabemedium auf zwei Seitenflächen 101, 102 des Kraftfahrzeugbauteils 100.During the delivery of the application medium, the nozzle device 1 and the motor vehicle component 100, in particular z. B. a fold, an edge or a transition seam of the motor vehicle component 100, essentially aligned with one another at the front. Nevertheless, as a result of the two inwardly directed beams S1, S2, the delivery medium hits two side surfaces 101, 102 of the motor vehicle component 100.

In der in Figur 2 gezeigten Ausführungsform treffen die Strahlen S1, S2 nur auf die Seitenflächen 101, 102 des Kraftfahrzeugbauteils 100. Allerdings sind Ausführungsformen möglich, bei denen die Strahlen S1, S2 auch auf die Stirnfläche 103 treffen. Die zwei Strahlen S1, S2 können also derart ausgerichtet werden, dass sie beim Auftreffen auf das Kraftfahrzeugbauteil 100 dieses zweckmäßig 3-seitig umschließen (umgreifen), so dass das Abgabemedium in vorteilhafter Weise nicht am Kraftfahrzeugbauteil 100 vorbeiappliziert werden muss.In the in Figure 2 The embodiment shown, the rays S1, S2 impinge only on the side surfaces 101, 102 of the motor vehicle component 100. However, embodiments are possible, in which the rays S1, S2 also hit the end face 103. The two beams S1, S2 can thus be aligned in such a way that when they strike the motor vehicle component 100 they expediently enclose (encompass) it on three sides, so that the delivery medium advantageously does not have to be applied past the motor vehicle component 100.

Die zwei Öffnungen 2.1, 2.2 sind so einwärts ausgerichtet, dass die zwei Strahlen S1, S2 einen Verjüngungswinkel β von ungefähr 120° einschließen, wobei allgemein auch Verjüngungswinkel β von größer 5°, größer 10°, größer 15°, größer 90°, größer 95° oder größer 100° und kleiner 180° möglich sind.The two openings 2.1, 2.2 are oriented inwardly so that the two rays S1, S2 enclose a taper angle β of approximately 120 °, generally also taper angles β of greater than 5 °, greater than 10 °, greater than 15 °, greater than 90 °, greater 95 ° or greater than 100 ° and less than 180 ° are possible.

In die Düsenvorrichtung 1 ist eine Materialaussparung 3, 4, 5 zur Zufuhr des Abgabemediums zu den zwei Öffnungen 2.1, 2.2 eingearbeitet. Die Materialaussparung 3, 4, 5 umfasst einen Leitungsabschnitt 3 für das Abgabemedium, über den das Abgabemedium den zwei Öffnungen 2.1, 2.2 zuführbar ist, so dass die zwei Öffnungen 2.1, 2.2 mit demselben Leitungsabschnitt 3 gemeinsam in Verbindung stehen. Der Leitungsabschnitt 3 wird in zwei Kanalabschnitte 4, 5 geteilt, wobei der eine Kanalabschnitt 4 zu der Öffnung 2.1 und der andere Kanalabschnitt 5 zu der Öffnung 2.2 führt.A material recess 3, 4, 5 for supplying the delivery medium to the two openings 2.1, 2.2 is incorporated into the nozzle device 1.
