Description

Die Erfindung betrifft eine Vorrichtung zum Auftragen eines viskosen Materials gemäß Oberbegriff des Anspruchs 1.The invention relates to a device for applying a viscous material according to the preamble of claim 1.

Vorrichtungen zum Auftragen eines viskosen Materials sind beispielsweise aus der EP 0 852 160 B1 bekannt und finden breite Anwendung beim Auftragen viskoser Materialien auf Werkstücke, beispielsweise beim Auftragen von Klebstoff auf Karosserieteile. Ein Auftragsrohr, aus dessen Materialaustrittsöffnung das viskose Material auf das Werkstück aufgetragen wird, ist dabei nahe seinem Ende in einem Exzenter gelagert, der während des Auftragsvorgangs in Rotation um seine Längsmittelachse versetzt wird und dem exzentrisch gelagerten Auftragsrohr an seiner die Materialaustrittsöffnung aufweisenden Spitze eine Kreisbewegung aufzwingt. Diese Kreisbewegung, die mit mehreren tausend Umdrehungen pro Minute erfolgt, lässt auf das viskose Material Fliehkräfte wirken, die zu einer spiralförmigen Bewegung des Materialstrahls führen. Dies bewirkt einen kreisförmigen Materialauftrag und führt zu einer Breite des aufgetragenen Materialstrangs, die wesentlich größer ist als der Durchmesser der Materialaustrittsöffnung. Das Auftragsrohr muss zu diesem Zweck zum einen zumindest über einen Großteil seiner Länge elastisch biegsam sein, zum anderen muss es eine hinreichend große Länge aufweisen, damit eine ausreichende Auslenkung seiner Spitze erzielt werden kann. Je länger das Auftragsrohr ist, desto mehr Material verbleibt nach Beendigung des Materialauftrags in ihm, und desto größer baut die Auftragsvorrichtung.Devices for applying a viscous material are for example from the EP 0 852 160 B1 known and are widely used when applying viscous materials to workpieces, for example when applying adhesive to body parts. An application tube, from the material outlet opening of which the viscous material is applied to the workpiece, is mounted near its end in an eccentric, which is set in rotation about its longitudinal central axis during the application process and forces the eccentrically mounted application tube at its tip with the material outlet opening to undergo a circular movement . This circular movement, which occurs at several thousand revolutions per minute, causes centrifugal forces to act on the viscous material, which lead to a spiral movement of the material jet. This causes a circular application of material and leads to a width of the applied strand of material that is substantially larger than the diameter of the material outlet opening. For this purpose, the application tube must on the one hand be elastically flexible over at least a large part of its length, on the other hand it must have a sufficiently large length so that a sufficient deflection of its tip can be achieved. The longer the application tube is, the more material remains in it after the material application has ended, and the larger the application device builds.

Eine Vorrichtung der eingangs genannten Art ist aus der DE 20 2007 016 237 U1 bekannt. Sie weist ein Auftragsrohr mit zwei gelenkig miteinander verbundenen Rohrabschnitten auf, wobei der die Materialaustrittsöffnung aufweisende zweite Rohrabschnitt gegenüber dem ersten Rohrabschnitt abgewinkelt werden kann. Die Abwinkelung erfolgt durch eine vom Werkstück auf den zweiten Rohrabschnitt ausgeübte Kraft. Dabei muss der zweite Rohrabschnitt das Werkstück berühren, und das Werkstück muss eine entsprechende Kontur aufweisen, da ohne äußere Kräfte keine Auslenkung erfolgen kann.A device of the type mentioned is from the DE 20 2007 016 237 U1 known. It has an application pipe with two pipe sections which are connected to one another in an articulated manner, wherein the second pipe section having the material outlet opening can be angled relative to the first pipe section. The bending takes place through a force exerted by the workpiece on the second pipe section. The second pipe section must touch the workpiece, and the workpiece must have a corresponding contour, since no deflection can take place without external forces.

Es ist daher Aufgabe der Erfindung, eine Vorrichtung der eingangs genannten Art derart weiterzubilden, dass eine gezielte Auslenkung des zweiten Rohrabschnitts relativ zum ersten Rohrabschnitt unabhängig von der Art des Werkstücks möglich ist.It is therefore an object of the invention to develop a device of the type mentioned in the introduction such that a targeted deflection of the second pipe section relative to the first pipe section is possible regardless of the type of workpiece.

Diese Aufgabe wird erfindungsgemäß durch eine Vorrichtung mit den Merkmalen des Anspruchs 1 gelöst. Vorteilhafte Weiterbildungen der Erfindung sind Gegenstand der abhängigen Ansprüche.This object is achieved according to the invention by a device with the features of claim 1. Advantageous developments of the invention are the subject of the dependent claims.

Der Erfindung liegt der Gedanke zugrunde, dass mittels des Gelenks eine Auslenkung der Materialaustrittsöffnung am freien Ende des zweiten Rohrabschnitts erzielt werden kann, ohne das Auftragsrohr verbiegen zu müssen. Der zweite Rohrabschnitt kann dabei recht kurz ausgeführt werden, ohne dabei auf eine hinreichend große Auslenkung seines freien Endes in Bezug auf eine Längsmittelachse des Auftragsrohrs verzichten zu müssen. Auch der erste Rohrabschnitt kann relativ kurz ausgeführt werden, wobei lediglich genügend Länge bereitgestellt werden muss, um das Material zuverlässig zuführen zu können. Die insgesamt kürzere Ausführung des Auftragsrohrs führt einerseits dazu, dass die gesamte Vorrichtung kleiner bauen kann, andererseits verbleibt nach dem Materialauftrag im kürzeren Auftragsrohr weniger Restmaterial als in einem längeren Auftragsrohr. Die erfindungsgemäße Vorrichtung hat gegenüber dem Stand der Technik zudem den Vorteil, dass bei entsprechender Ausbildung und Ansteuerung der Antriebseinrichtung die Exzentrizität der Materialaustrittsöffnung stufenlos und schnell geändert werden kann. Zudem erfolgt der Auftrag nicht zwingend kreisförmig, sondern kann durch entsprechende Ansteuerung der Antriebseinrichtung andere Formen annehmen. Schließlich kann die Antriebseinrichtung ausgeschaltet werden, so dass der Materialauftrag in einer dünnen geraden Linie erfolgen kann, und der zweite Rohrabschnitt kann quer zum ersten Rohrabschnitt angeordnet und in dieser Stellung festgehalten werden, so dass ein Auftrag des Materials in einer Richtung quer zur Längsmittelachse des ersten Rohrabschnitts erfolgt.The invention is based on the idea that a deflection of the material outlet opening at the free end of the second tube section can be achieved by means of the joint without having to bend the application tube. The second pipe section can be made quite short without having to forego a sufficiently large deflection of its free end with respect to a longitudinal central axis of the application pipe. The first pipe section can also be made relatively short, only enough length having to be provided in order to be able to reliably feed the material. The overall shorter design of the application tube on the one hand means that the entire device can be made smaller, on the other hand, less material remains in the shorter application tube after application of the material than in a longer application tube. The device according to the invention also has the advantage over the prior art that, with the appropriate design and control of the drive device, the eccentricity of the material outlet opening can be changed continuously and quickly. In addition, the application is not necessarily circular, but can take other forms by appropriately controlling the drive device. Finally, the drive device can be switched off so that the material can be applied in a thin straight line, and the second pipe section can be arranged transversely to the first pipe section and held in this position so that an application of the material in a direction transverse to the longitudinal central axis of the first Pipe section takes place.

Als Gelenk kommt insbesondere ein Kugelgelenk in Frage. Es ist aber auch möglich, das Gelenk als Kardan- bzw. Kreuzgelenk oder als ein Gelenk mit einem den ersten Rohrabschnitt mit dem zweiten Rohrabschnitt verbindenden elastischen Verbindungselement auszubilden. Insbesondere kommt bei der letzteren Ausführungsform ein Silentblock in Frage, bei dem die Rohrabschnitte an den einander zugewandten Enden jeweils eine Buchse tragen, wobei die Buchsen ineinander gesteckt sind und zwischen ihnen eine elastische Zwischenschicht angeordnet ist.A ball joint is particularly suitable as a joint. But it is also possible to connect the joint as a cardan or universal joint or as a joint with a pipe section connecting the first pipe section to the second pipe section to form elastic connecting element. In particular, in the latter embodiment, a silent block comes into question, in which the pipe sections each carry a bushing at the ends facing one another, the bushings being inserted into one another and an elastic intermediate layer being arranged between them.

Erfindungsgemäß weist die Antriebseinrichtung mindestens einen fest mit dem zweiten Rohrabschnitt verbundenen und radial abstehenden Ausleger sowie mindestens zwei mittels jeweils eines Stellglieds bewegbare Betätigungselemente zur Beaufschlagung des mindestens einen Auslegers an verschiedenen Beaufschlagungsstellen auf. Der Ausleger kann eine Platte sein, die rings um den zweiten Rohrabschnitt von diesem absteht. Es wird jedoch bevorzugt, dass die Antriebseinrichtung eine der Zahl der Betätigungselemente entsprechende Zahl von im Winkelabstand zueinander radial abstehenden Auslegern in Form von Auslegerarmen aufweist, so dass weniger Material benötigt wird und weniger Masse bewegt werden muss.According to the invention, the drive device has at least one radially projecting arm which is fixedly connected to the second pipe section and at least two actuating elements which can be moved by means of an actuator in each case to act on the at least one arm at different points of action. The cantilever can be a plate which projects around the second pipe section from the latter. However, it is preferred that the drive device has a number corresponding to the number of actuating elements of cantilevers which protrude radially from one another in the form of cantilever arms, so that less material is required and less mass has to be moved.

Wenn die Antriebseinrichtung lediglich zwei Betätigungselemente aufweist, ist nur eine Hin- und Herbewegung der Materialauftragsöffnung möglich. Es wird daher bevorzugt, dass die Antriebseinrichtung mindestens drei Betätigungselemente aufweist, idealerweise eine noch größere Anzahl, um eine möglichst präzise Bewegung der Materialaustrittsöffnung auch annähernd in einer Kreisbahn zu ermöglichen. Dabei wird bevorzugt, dass sowohl die Betätigungselemente als auch die Beaufschlagungsstellen jeweils in konstanten Winkelabständen zueinander bezüglich einer Längsmittelachse des Auftragsrohrs angeordnet sind, so dass ein hohes Maß an Symmetrie gegeben ist.If the drive device has only two actuating elements, only a reciprocating movement of the material application opening is possible. It is therefore preferred that the drive device has at least three actuating elements, ideally an even larger number, in order to enable the material outlet opening to move as precisely as possible, also approximately in a circular path. It is preferred that both the actuating elements and the loading points are each arranged at constant angular distances from one another with respect to a longitudinal center axis of the application tube, so that there is a high degree of symmetry.

Zweckmäßig sind die Betätigungselemente hin und her bewegliche, auf dem mindestens einen Ausleger an den Beaufschlagungsstellen lose aufliegende Stößel. Eine aufwendige Befestigung der Betätigungselemente am mindestens einen Ausleger kann damit entfallen. Ein Rückhub des mindestens einen Auslegers erfolgt dann durch Beaufschlagung an einer anderen Beaufschlagungsstelle mittels eines anderen Stößels. Es ist jedoch auch möglich, dass jedem Stößel eine Rückstellfeder zur Beaufschlagung des mindestens einen Auslegers mit einer zum Stößel hin gerichteten Rückstellkraft zugeordnet ist, die dann den Rückhub ausführt oder unterstützt.The actuating elements are expediently movable back and forth plungers loosely resting on the at least one arm at the points of application. A complex attachment of the actuating elements to the at least one arm can thus be dispensed with. A return stroke of the at least one boom is then carried out by acting on another point of application by means of another ram. However, it is also possible that everyone Plunger is assigned a return spring to act on the at least one arm with a restoring force directed towards the plunger, which then executes or supports the return stroke.

Als Stellglieder kommen eine Vielzahl von gebräuchlichen Bauteilen in Frage. Insbesondere ist es möglich, die Stellglieder als Pneumatikzylinder oder Piezo-Elemente auszuführen. Es wird jedoch bevorzugt, dass die Stellglieder Schwingspulen (Voice Coils) sind, die eine besonders schnelle Ansteuerung ermöglichen.A variety of common components can be used as actuators. In particular, it is possible to design the actuators as pneumatic cylinders or piezo elements. However, it is preferred that the actuators are voice coils that enable particularly fast control.

Zweckmäßig weist die erfindungsgemäße Vorrichtung ein Nadelventil zum Verschließen des Auftragsrohrs auf, dessen Ventilsitz im ersten Rohrabschnitt angeordnet ist. Insbesondere kann der Ventilsitz nahe dem Gelenk angeordnet sein, so dass nach Beendigung des Auftragsvorgangs und Schließen des Nadelventils nur sehr wenig Restmaterial auf der der Austrittsöffnung zugewandten Seite des Nadelventils verbleibt, das aus der Materialaustrittsöffnung tropfen kann. Gemäß einer vorteilhaften Weiterbildung weist die Nadel des Nadelventils einen sich in den zweiten Rohrabschnitt erstreckenden Fortsatz auf, der als Verdrängungskörper wirkt und die Menge des nach dem Auftragsvorgang im zweiten Rohrabschnitt verbleibenden Restmaterials weiter reduziert.The device according to the invention expediently has a needle valve for closing the application tube, the valve seat of which is arranged in the first tube section. In particular, the valve seat can be arranged near the joint, so that after the application process has ended and the needle valve has closed, very little residual material remains on the side of the needle valve facing the outlet opening, which can drip out of the material outlet opening. According to an advantageous development, the needle of the needle valve has an extension which extends into the second tube section and acts as a displacement body and further reduces the amount of residual material remaining in the second tube section after the application process.

Im Folgenden wird die Erfindung anhand eines in der Zeichnung schematisch dargestellten Ausführungsbeispiels näher erläutert. Es zeigen

It has a housing 12, in which an application tube 14 is received, which extends in a longitudinal direction 16. The application tube 14 has a first tube section 18 which is fixed to the housing and has a material inlet opening 20, and a second tube section 24 which is articulated by means of a ball joint 22 to the first tube section 18 and which has a material outlet opening 28 at its free end 26 facing away from the first tube section 18 . Between the material inlet opening 20 and the material outlet opening 28 there extends an application channel 30 for the viscous material which is delimited by the application tube 14 and into which this is introduced via a material feed connection 32 in the housing 12 through the material inlet opening 20.

Jeder der Auslegerarme 38 wird an einer im Abstand zum zweiten Rohrabschnitt 24 angeordneten Beaufschlagungsstelle 40 an seiner Oberseite von einem dort lose aufliegenden Stößel 42 beaufschlagt. Alle Beaufschlagungsstellen 40 sind im gleichen Abstand zum zweiten Rohrabschnitt 24 angeordnet. Zur Bewegung der Stößel 42 weist die Antriebseinrichtung 36 vier im Gehäuse 12 angeordnete, in der Zeichnung lediglich angedeutete Schwingspulen (Voice Coils) 44 auf, von denen jede dazu bestimmt ist, einen der Stößel 42 zur Erzielung einer Hin- und Herbewegung zu beaufschlagen. Bei einer entsprechenden Ansteuerung der Schwingspulen 44, bei der die Stößel 42 sukzessive reihum zur Beaufschlagung der Auslegerarme 38 auf die Beaufschlagungsstellen 40 nach unten bewegt werden, kann eine annähernde Kreisbewegung des freien Endes 26 und somit der Materialaustrittsöffnung 28 erzielt werden. Den Stößeln 42 gegenüber liegend können Rückstellfedern im Gehäuse 12 angeordnet sein, die von unten gegen die Auslegerarme 38 wirken.In order to be able to pivot the second pipe section 24 relative to the first pipe section 18 on the ball joint 22 by deflecting the free end 26 relative to the longitudinal central axis of the application pipe 14 in a transverse direction 34 running transversely to the longitudinal direction 16, a drive device 36 is provided which has four cross-shaped shapes at equal angular intervals mutually arranged, connected to the second pipe section 24 and radially projecting boom in the form of boom arms 38. Each of the cantilever arms 38 is acted upon by a plunger 42 lying loosely there at a loading point 40 arranged at a distance from the second pipe section 24. All loading points 40 are arranged at the same distance from the second pipe section 24. To move the plungers 42, the drive device 36 has four voice coils 44 arranged in the housing 12, only indicated in the drawing, each of which is intended to act on one of the plungers 42 in order to achieve a back and forth movement. With a corresponding control of the voice coils 44, in which the plungers 42 are successively moved downwards in order to act on the cantilever arms 38 on the acted upon points 40, an approximate circular movement of the free end 26 and thus the material outlet opening 28 can be achieved. The plungers 42 opposite Return springs can be arranged lying in the housing 12, which act against the extension arms 38 from below.

Zum Verschließen des Auftragskanals 30 ist ein Nadelventil 46 vorgesehen, dessen Nadel 48 in einer Schließstellung auf einem Ventilsitz 50 im ersten Rohrabschnitt 18 aufsitzt. Der Ventilsitz 50 ist dabei knapp oberhalb des Kugelgelenks 22 angeordnet. Ein typischer Wert für den Abstand des Ventilsitzes 50 vom Kugelgelenk 22 ist dabei ein bis zwei cm, während ein typischer Wert für die Länge des zweiten Rohrabschnitts 24 drei bis fünf cm ist. Die Nadel 48 weist zudem einen sich durch das Kugelgelenk in den zweiten Rohrabschnitt 24 erstreckenden Fortsatz 52 mit geringerem Durchmesser auf, der auch bei einer Auslenkung des zweiten Rohrabschnitts 24 mittels Verschwenken gegenüber dem ersten Rohrabschnitt 18 um das Kugelgelenk 22 in ausreichendem Abstand vom zweiten Rohrabschnitt 24 angeordnet ist. Der Fortsatz 52 dient als Verdrängungskörper, um die nach dem Schließen des Nadelventils 46 in dem zwischen dem Ventilsitz 50 und der Materialaustrittsöffnung 28 liegenden Bereich des Auftragsrohrs 14 verbleibenden Menge an Restmaterial zu minimieren.To close the application channel 30, a needle valve 46 is provided, the needle 48 of which is seated on a valve seat 50 in the first tube section 18 in a closed position. The valve seat 50 is arranged just above the ball joint 22. A typical value for the distance of the valve seat 50 from the ball joint 22 is one to two cm, while a typical value for the length of the second pipe section 24 is three to five cm. The needle 48 also has an extension 52 with a smaller diameter which extends through the ball joint into the second pipe section 24 and which, even when the second pipe section 24 is deflected by pivoting relative to the first pipe section 18 about the ball joint 22, is at a sufficient distance from the second pipe section 24 is arranged. The extension 52 serves as a displacement body in order to minimize the amount of residual material remaining after the closing of the needle valve 46 in the region of the application tube 14 lying between the valve seat 50 and the material outlet opening 28.

Der erste Rohrabschnitt 18 und der zweite Rohrabschnitt 24 können jeweils einstückig ausgebildet oder, wie im Ausführungsbeispiel gezeigt, aus mehreren Bauteilen zusammengesetzt sein. Insbesondere kann der erste Rohrabschnitt 18, wie in der Zeichnung dargestellt, eine im Abstand zum Kugelgelenk 22 angeordnete Buchse aufweisen, in der die Materialeintrittsöffnung 20 angeordnet ist.The first pipe section 18 and the second pipe section 24 can each be formed in one piece or, as shown in the exemplary embodiment, can be composed of several components. In particular, the first tube section 18, as shown in the drawing, can have a bushing which is arranged at a distance from the ball joint 22 and in which the material inlet opening 20 is arranged.
