Definitions

  • the invention relates to a nozzle device for dispensing at least one viscous, in particular highly viscous dispensing medium onto a component, preferably for dispensing the dispensing medium onto 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 (z. B. a commercial vehicle body part), a component of an aircraft, a window (z. B. a window pane) or a facade component.
  • a nozzle device with nozzle plates arranged next to one another for the delivery of a plurality of jets of a medium of high viscosity is in itself off US 4,476,165A known.
  • U.S. 2013/011552 A1 discloses a nozzle assembly for dispensing liquid adhesive having a plurality of nozzle plates from which the adhesive is dispensed between converging jets of compressed air.
  • standing seams (z. B. component edges), as z. B. occur in the sill area or on the side members of a motor vehicle, using conventional, robot-guided flat jet nozzles (also called flatstream nozzles) made of hard metal.
  • PVC polyvinyl chloride
  • the standing seam is sealed with PVC (PVC: polyvinyl chloride) on at least one and possibly also on both sides.
  • 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 under the standing seam and thus past it (“shot past”).
  • the pvc material which is applied to one side of the standing seam, wraps around the seam edge to a certain extent and thus seals the lower side of the standing seam, which is susceptible to corrosion.
  • 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 slit opening of the conventional flat spray 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 PVC material released is “shot past” the standing seam due to the process. The consequence of this is that the robot guiding the flat jet nozzle and/or the application cell in which the method is carried out becomes soiled, and this results in an increased cleaning effort. Due to component tolerances that are usually present in motor vehicle bodies, the application usually cannot be adjusted differently. The component tolerances also mean that the standing seam has to be applied from both sides. Joined sheet metal edges e.g. B. differ in length from body to body.
  • An object of the invention is to create a possibility, by means of the application processes for dispensing a viscous dispensing medium onto a component, e.g. B. a fold, an edge or a transition seam of the component, are flexible and can therefore be carried out efficiently and preferably in addition the required amount of the release medium can be reduced.

Description

Die Erfindung betrifft eine Düsenvorrichtung zur Abgabe zumindest eines viskosen, insbesondere hochviskosen Abgabemediums auf ein Bauteil, vorzugsweise zur Abgabe des Abgabemediums auf einen Falz (z. B. Stehfalz), eine Kante oder eine Übergangsnaht des Bauteils. 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 at least one viscous, in particular highly viscous dispensing medium onto a component, preferably for dispensing the dispensing medium onto 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 (z. B. a commercial vehicle body part), a component of an aircraft, a window (z. B. a window pane) or a facade component.

Eine Düsenvorrichtung mit nebeneinander angeordneten Düsenplatten zur Abgabe mehrerer Strahlen eines Mediums hoher Viskosität ist an sich aus US 4,476,165 A bekannt.A nozzle device with nozzle plates arranged next to one another for the delivery of a plurality of jets of a medium of high viscosity is in itself off US 4,476,165A known.

US 2013/011552 A1 offenbart eine Düsenvorrichtung zur Abgabe von flüssigem Klebstoff mit mehreren Düsenplatten, aus denen der Klebstoff zwischen zueinander konvergierenden Druckluftstrahlen abgegeben wird. U.S. 2013/011552 A1 discloses a nozzle assembly for dispensing liquid adhesive having a plurality of nozzle plates from which the adhesive is dispensed between converging jets of compressed air.

Zum allgemeinen Stand der Technik kann ferner auf die DE 10 2013 217 686 A1 verwiesen werden.The general state of the art can also be found on the DE 10 2013 217 686 A1 to get expelled.

Unter Bezugnahme auf Figur 14 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 14 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, using conventional, robot-guided flat jet nozzles (also called flatstream nozzles) made of hard metal. With this method, the standing seam is sealed with PVC (PVC: polyvinyl chloride) on at least one and possibly also on both sides. So that the underside of the standing seam can also be sealed reliably, 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 under the standing seam and thus past it ("shot past"). the pvc material, which is applied to one side of the standing seam, wraps around the seam edge to a certain extent and thus seals the lower side of the standing seam, which is susceptible to corrosion.

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 slit opening of the conventional flat spray 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 PVC material released is “shot past” the standing seam due to the process. The consequence of this is that the robot guiding the flat jet nozzle and/or the application cell in which the method is carried out becomes soiled, and this results in an increased cleaning effort. Due to component tolerances that are usually present in motor vehicle bodies, the application usually cannot be adjusted differently. The component tolerances also mean that the standing seam has to be applied from both sides. Joined sheet metal edges e.g. B. differ in length from body to body.

Nachteilig bei dem zuvor beschriebenen Stand der Technik ist zusätzlich die Unflexibilität. So müssen in Abhängigkeit unterschiedlicher Qualitätsanforderungen oder in Abhängigkeit unterschiedlicher Konfigurationen des mit dem Abgabemedium zu versehenden Kraftfahrzeugbauteils unterschiedliche Düsen verwendet werden. Düsenwechselvorgänge sind aber zeitaufwendig und stören den eigentlichen Applikationsprozess.Another disadvantage of the prior art described above is its inflexibility. Depending on different quality requirements or depending on different configurations of the motor vehicle component to be provided with the dispensing medium, different nozzles must be used. However, nozzle changing processes are time-consuming and disrupt the actual application process.

Eine Aufgabe der Erfindung ist es, eine Möglichkeit zu schaffen, mittels der Applikationsprozesse zur Abgabe eines viskosen Abgabemediums auf ein Bauteil, z. B. einen Falz, eine Kante oder eine Übergangsnaht des Bauteils, flexibel und somit effizient durchführbar sind und vorzugsweise zusätzlich die erforderliche Menge des Abgabemediums reduziert werden kann.An object of the invention is to create a possibility, by means of the application processes for dispensing a viscous dispensing medium onto a component, e.g. B. a fold, an edge or a transition seam of the component, are flexible and can therefore be carried out efficiently and preferably in addition the required amount of the release medium can be reduced.

Diese Aufgabe kann mit den Merkmalen des unabhängigen Anspruchs gelöst werden. Vorteilhafte Weiterbildungen der Erfindung können den abhängigen Ansprüchen und der folgenden Beschreibung bevorzugter Ausführungsformen der Erfindung entnommen werden.This problem can be solved with the features of the independent claim. Advantageous developments of the invention can be found in the dependent claims and the following description of preferred embodiments of the invention.

Die Erfindung betrifft eine Düsenvorrichtung zur Abgabe zumindest eines Abgabemediums auf ein Bauteil, vorzugsweise auf einen Falz (z. B. Stehfalz), eine Kante oder eine Übergangsnaht des Bauteils.The invention relates to a nozzle device for dispensing at least one dispensing medium onto a component, preferably onto a fold (e.g. standing seam), an edge or a transition seam of the component.

Das Bauteil ist vorzugsweise ein Kraftfahrzeugbauteil, z. B. eine Kraftfahrzeugkarosserie.The component is preferably a motor vehicle component, e.g. B. a motor vehicle body.

Das Bauteil 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 component can also z. B. a component of a commercial vehicle (z. B. a commercial vehicle body part), a component of an aircraft, a window (z. B. a window pane) or a facade component.

Anwendungsbereiche der Düsenvorrichtung sind somit insbesondere: Kraftfahrzeuge, Nutzfahrzeuge, Luftfahrzeuge, Fenster und/oder der Fassadenbau.Areas of application for the nozzle device are therefore in particular: motor vehicles, commercial vehicles, aircraft, windows and/or facade construction.

Die Düsenvorrichtung umfasst zumindest zwei, vorzugsweise zumindest drei, nebeneinander angeordnete Düsenplatten, insbesondere im Wesentlichen parallel nebeneinander angeordnete Düsenplatten.The nozzle device comprises at least two, preferably at least three, nozzle plates arranged next to one another, in particular Nozzle plates arranged essentially parallel next to one another.

Eine erste Düsenplatte umfasst zumindest eine Öffnung zur Abgabe zumindest eines Abgabestrahls und eine zweite Düsenplatte umfasst zumindest zwei Öffnungen zur Abgabe von zumindest zwei Abgabestrahlen. Somit ist z. B. auch eine Düsenplatte mit zumindest drei Öffnungen möglich.A first nozzle plate comprises at least one opening for discharging at least one discharge jet and a second nozzle plate comprises at least two openings for discharging at least two discharge jets. Thus e.g. B. also a nozzle plate with at least three openings possible.

Dadurch, dass die Düsenvorrichtung zumindest drei Öffnungen aufweist, können mit ein und derselben Düsenvorrichtung unterschiedliche Qualitätsanforderungen realisiert werden und/oder unterschiedliche Konfigurationen des mit dem Abgabemedium zu versehenden Bauteils bearbeitet werden und zwar insbesondere ohne einen Düsenwechsel. So kann z. B. der Strahl aus der ersten Düsenplatte für einen ganz bestimmten Verwendungszweck genutzt werden, wobei die Strahlen aus der zweiten Düsenplatte für einen anderen Verwendungszweck genutzt werden können. Alternativ oder ergänzend kann der Strahl aus der ersten Düsenplatte und die Strahlen aus der zweiten Düsenplatte in Abhängigkeit des Verwendungszwecks z. B. auch gleichzeitig ausgegeben werden.Because the nozzle device has at least three openings, different quality requirements can be realized with one and the same nozzle device and/or different configurations of the component to be provided with the dispensing medium can be processed, in particular without changing the nozzle. So e.g. For example, the jet from the first nozzle plate can be used for a specific purpose, while the jets from the second nozzle plate can be used for a different purpose. Alternatively or in addition, the beam from the first nozzle plate and the beams from the second nozzle plate can, depending on the intended use, e.g. B. also be issued simultaneously.

Gemäß einer Alternative der Erfindung es ist möglich, dass der zumindest eine Abgabestrahl aus der ersten Düsenplatte eine Strahlbreite definiert und die erste Düsenplatte eine Öffnungskonfiguration zur Ausbildung der zumindest einen Öffnung aufweist und die Öffnungskonfiguration konkav, insbesondere gekrümmt konkav, ausgeformt ist, um eine Verschmälerung der Strahlbreite zur Abgabeseite hin zu bewirken.According to an alternative of the invention, it is possible that the at least one delivery jet from the first nozzle plate defines a jet width and the first nozzle plate has an opening configuration for forming the at least one opening and the opening configuration is concave, in particular curved concave, in order to narrow the To effect beam width towards the delivery side.

Die Strahlbreite kann z. B. einen einzigen Abgabestrahl umfassen, falls die Öffnungskonfiguration nur eine einzige Öffnung zur Abgabe eines einzigen Abgabestrahls aufweist.The beam width can e.g. B. comprise a single emission jet, if the aperture configuration has only a single aperture for delivery of a single emission jet.

Die Strahlbreite kann z. B. zumindest zwei Abgabestrahlen umfassen, falls die Öffnungskonfiguration zumindest zwei Öffnungen zur Abgabe zumindest zweier Abgabestrahlen aufweist. Die zumindest zwei Abgabestrahlen können eine die zumindest zwei Abgabestrahlen umfassende Strahlbreite definieren, so dass eine Verschmälerung der die zumindest zwei Abgabestrahlen umfassenden Strahlbreite zur Abgabeseite hin bewirkt werden kann.The beam width can e.g. B. comprise at least two emission jets, if the opening configuration has at least two openings for the emission of at least two emission jets. The at least two emission beams can define a beam width comprising the at least two emission beams, so that the beam width comprising the at least two emission beams can be narrowed towards the emission side.

Gemäß einer weiteren Alternative der Erfindung es ist möglich, dass die zumindest zwei Öffnungen der zweiten Düsenplatte einwärts ausgerichtet sind, so dass die zumindest zwei Abgabestrahlen der zweiten Düsenplatte sich zur Abgabeseite hin einander annähern. Die zwei Abgabestrahlen können z. B. einen Verjüngungswinkel bilden von größer 5°, größer 10°, größer 15°, größer 90°, größer 95° oder größer 100° und kleiner 180°.According to a further alternative of the invention, it is possible for the at least two openings of the second nozzle plate to be aligned inwards, so that the at least two discharge jets of the second nozzle plate approach one another on the discharge side. The two emission beams can e.g. B. form a taper angle of greater than 5°, greater than 10°, greater than 15°, greater than 90°, greater than 95° or greater than 100° and less than 180°.

Durch die Bereitstellung mehrerer Öffnungen und vorzugsweise der Verschmälerung der Strahlbreite und/oder der sich einander annähernden Abgabestrahlen können z. B. eine oder mehrere der folgenden Vorteile erzielt werden:

  • Der Verbrauch an Abgabemedium kann reduziert werden.
  • Die Verschmutzung einer Applikationszelle kann reduziert werden.
  • Eine prozesssichere Abdichtung unterschiedlicher Falzarten, insbesondere Stehfalze, kann ermöglicht werden.
  • Auf ein Bauteilvermessungssystem zur Vermessung des (Kraftfahrzeug-) Bauteils kann verzichtet werden.
  • Eine hohe Applikationsgeschwindigkeit kann erzielt werden, insbesondere gegenüber Applikationsverfahren mit Bauteilvermessung.
  • Ein größerer Spritzabstand zwischen Düsenvorrichtung und (Kraftfahrzeug-) Bauteil kann ermöglicht werden, z. B. bis zu 50mm.
  • Größere Bauteiltoleranzen können ermöglicht werden, z. B. +/- 3mm bis 5mm.
  • Aufgrund der einfachen Bauform der Düsenvorrichtung entsteht vorzugsweise keine zusätzliche Störkontur am Applikator und/oder am Roboter, so dass z. B. auch schwer zugängliche Stellen, z. B. Falze, Nähte, Kanten, etc., gut erreicht werden können.
  • Durch Erhöhung der Ausflussrate des Abgabemediums kann ermöglicht werden, auch eine konventionelle Naht, z. B. aus PVC, auf das (Kraftfahrzeug-) Bauteil aufzutragen.
By providing multiple apertures and preferably narrowing the jet width and/or the output jets approaching each other, e.g. B. one or more of the following advantages can be achieved:
  • The consumption of delivery medium can be reduced.
  • Contamination of an application cell can be reduced.
  • A process-reliable sealing of different types of seams, especially standing seams, can be made possible.
  • A component measurement system for measuring the (vehicle) component can be dispensed with.
  • A high application speed can be achieved, in particular compared to application methods with component measurement.
  • A larger spray distance between the nozzle device and (motor vehicle) component can be made possible, e.g. B. up to 50mm.
  • Greater component tolerances can be made possible, e.g. B. +/- 3mm to 5mm.
  • Due to the simple design of the nozzle device, there is preferably no additional interfering contour on the applicator and/or on the robot, so that z. B. also hard-to-reach places, z. B. folds, seams, edges, etc., can be easily reached.
  • By increasing the outflow rate of the delivery medium, a conventional suture, e.g. B. from PVC, to apply to the (motor vehicle) component.

Die Düsenvorrichtung eignet sich insbesondere für zumindest eine der folgenden Anwendungsmöglichkeiten:

  • Abdichtung von z. B. metallischen (Kraftfahrzeug-) Bauteilen, die geschweißt oder geklebt werden, z. B. Falze (insbesondere Stehfalze) oder Übergangsnähte, aber auch z. B. Bauteilkanten einzelner Bauteile.
  • Z. B. 3-seitig umgreifende (umschließende) Applikation (Beschichtung) eines z. B. viskosen oder hochviskosen Abgabemediums auf ein (Kraftfahrzeug-) Bauteil, zum Korrosionsschutz von Schnittkanten an z. B. Blechen, Schutz vor Verletzungen beim manuellen Bauteilhandling (z. B. bei scharfkantigen Blechkanten), Schutz vor Kantenbeschädigung (z. B. bei Faserverbundwerkstoffen) und/oder Scheuerschutz.

The opening configuration K is expediently curved and concave and preferably comprises a dividing section T for forming (expediently separating) the two openings 1.1, 1.2.

Die zwei Strahlen S1.1, S1.2 definieren eine die zwei Strahlen S1.1, S1.2 umfassende Strahlbreite B1, B2. Dadurch, dass die Öffnungskonfiguration K vorzugsweise gekrümmt konkav ausgeformt ist, kann eine Verschmälerung der die zwei Strahlen S1.1, S1.2 umfassenden Strahlbreite B1, B2 zur Abgabeseite A hin bewirkt werden. Die Hornstruktur 3.1, 3.2 ist optional. Die zwei Öffnungen 1.1, 1.2 sind zugleich einwärts ausgerichtet, so dass die zwei Abgabestrahlen S1.1, S1.2 sich zur Abgabeseite A hin einander annähern.The two beams S1.1, S1.2 define a beam width B1, B2 encompassing the two beams S1.1, S1.2. Due to the fact that the opening configuration K is preferably curved and concave, the beam width B1, B2 comprising the two beams S1.1, S1.2 can be narrowed towards the discharge side A. The horn structure 3.1, 3.2 is optional. The two openings 1.1, 1.2 are also oriented inwards, so that the two emission beams S1.1, S1.2 approach one another towards the emission side A.

Die in Figur 12 gezeigte Düsenplatte kann vorteilhaft auch als zweite Düsenplatte genutzt werden, weil sie zwei Öffnungen zur Abgabe von zwei Abgabestrahlen aufweist und vorzugsweise die zwei Öffnungen einwärts ausgerichtet sind, so dass die zwei Abgabestrahlen sich zur Abgabeseite hin einander annähern.In the figure 12 The nozzle plate shown can advantageously also be used as a second nozzle plate because it has two openings for the delivery of two delivery jets and preferably the two openings are oriented inwards, so that the two delivery jets approach one another towards the delivery side.
