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 zumindest über einen Teil seiner Länge elastisch biegsam sein. Als nachteilig an den bekannten Vorrichtungen wird aber kritisiert, dass das Profil des aufgetragenen Materialstrangs nur begrenzt über eine Variation der Drehzahl des Exzenters oder, abhängig vom Material, über den Volumenstrom oder über den Abstand der Düse zum Werkstück möglich ist, was zudem recht ungenau ist.Devices for applying a viscous material are for example from EP 0 852 160 B1 known and find wide application when applying viscous materials on workpieces, for example, when applying adhesive to body parts. An applicator tube, from the material outlet opening the viscous material is applied to the workpiece, is mounted near its end in an eccentric, which is offset during the application process in rotation about its longitudinal central axis and the eccentrically mounted applicator tube at its the material outlet opening having tip forces a circular motion , This circular movement, which takes place at several thousand revolutions per minute, causes centrifugal forces to act on the viscous material, which lead to a spiraling movement of the material jet. This causes a circular material application and leads to a width of the applied material strand, which is substantially larger than the diameter of the material outlet opening. The applicator tube must be elastically flexible for at least a portion of its length for this purpose. As a disadvantage of the known devices but criticized that the profile of the applied material strand is limited on a variation of the rotational speed of the eccentric or, depending on the material, on the volume flow or the distance of the nozzle to the workpiece is possible, which is also quite inaccurate ,

Aus der DE 10 2004 062 063 A1 ist zudem eine Vorrichtung der eingangs genannten Art bekannt, bei der die Exzentrizität des Exzenters mittels eines Elektromagneten variiert werden kann. Dies ist aufwendig und schränkt die Materialwahl für das Auftragsrohr ein.From the DE 10 2004 062 063 A1 In addition, a device of the aforementioned type is known in which the eccentricity of the eccentric can be varied by means of an electromagnet. This is expensive and limits the choice of material for the order pipe.

Es ist Aufgabe der Erfindung, eine Vorrichtung der eingangs genannten Art derart zu verbessern, dass das Profil eines aufgetragenen Materialstrangs einfacher variiert werden kann.It is an object of the invention to improve a device of the type mentioned in such a way that the profile of a deposited strand of material can be varied easily.

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

Der Erfindung liegt der Gedanke zugrunde, eine Änderung des Auftragsprofils durch Variation der Exzentrizität des Exzenters zu erzielen, in dem das Auftragsrohr gelagert ist. Der Bereich des zumindest abschnittsweise elastisch biegsamen Auftragsrohrs, der im Exzenter gelagert ist, wird im Folgenden als Lagerabschnitt bezeichnet. Die Variation der Exzentrizität erfolgt erfindungsgemäß mittels eines Verstellmechanismus, durch den der Abstand des Lagerabschnitts zur Längsmittelachse verstellbar ist.The invention is based on the idea of achieving a change in the application profile by varying the eccentricity of the eccentric in which the application tube is mounted. The region of the at least partially elastically flexible application tube, which is mounted in the eccentric, is referred to below as the bearing section. The variation of the eccentricity takes place according to the invention by means of an adjusting mechanism by which the distance of the bearing section to the longitudinal center axis is adjustable.

Die Variation der Exzentrizität wird dadurch ermöglicht, dass der Exzenter zweiteilig ausgebildet ist mit einem motorisch drehbaren Außenkörper und einem im Außenkörper aufgenommenen Innenkörper, der beim Drehen des Außenkörpers von diesem mitgenommen wird. Der Lagerabschnitt des Auftragsrohrs ist im Innenkörper mittels eines Drehlagers gelagert, so dass er sich bei der Drehung des Exzenters nicht mitdreht. Dabei wird bevorzugt, das der Innenkörper bezüglich des Außenkörpers zwischen zwei Endstellungen beweglich ist, die eine minimal und eine maximal exzentrische Stellung des Lagerabschnitts bezüglich der Längsmittelachse definieren. Die minimal exzentrische Stellung kann dabei eine Exzentrizität des Lagerabschnitts von Null definieren, so dass der Materialauftrag ohne kreisförmige Materialverteilung erfolgt.The variation of the eccentricity is made possible by the fact that the eccentric is formed in two parts with a motor-rotatable outer body and an inner body received in the outer body, which is entrained when turning the outer body of this. The bearing portion of the applicator tube is mounted in the inner body by means of a pivot bearing, so that it does not rotate with the rotation of the eccentric. It is preferred that the inner body with respect to the outer body between two end positions is movable, which define a minimum and a maximum eccentric position of the bearing portion with respect to the longitudinal center axis. The minimal eccentric position can define an eccentricity of the bearing section of zero, so that the material is applied without a circular distribution of material.

Gemäß einer ersten Ausführungsform ist der Innenkörper außermittig im Außenkörper aufgenommen und bezüglich des Außenkörpers verdrehbar, so dass ein Verdrehen eine Veränderung der Exzentrizität des Lagerabschnitts des Auftragsrohrs bewirkt. Dabei weist der Exzenter zweckmäßig einen Verdrehmechanismus zum Verdrehen des Innenkörpers bezüglich des Außenkörpers auf, der einen in einer Führungskulisse geführten, radial abstehenden Zapfen aufweist, wobei die Führungskulisse im wesentlichen die Form eines Wendelabschnitts aufweist. Dabei ist der Zapfen vorzugsweise in der Führungskulisse zwischen zwei Endanschlägen geführt, die zwei Endstellungen des Innenkörpers bezüglich des Außenkörpers definieren. Die Zwangsführung des Zapfens in der wendelabschnittförmigen Führungskulisse ermöglicht eine Umwandlung einer Translationsbewegung in eine Rotationsbewegung. Wird der Innenkörper in Richtung der Mittellängsachse gegenüber dem Außenkörper bewegt, so findet zwangsläufig eine Verdrehung beider Körper zueinander statt, die eine Variation der resultierenden Exzentrizität bewirkt. Dies ist besonders dann vorteilhaft, wenn das Auftragsrohr axial unverschieblich im Innenkörper und im Gehäuse begrenzt axial verschieblich gelagert ist, so dass über eine Verschiebung des Auftragsrohrs in Richtung der Längsmittelachse ein Verdrehen des Innenkörpers bezüglich des Außenkörpers erfolgen kann. Dabei ist gemäß einem bevorzugten Ausführungsbeispiel der Zapfen fest mit dem Innenkörper verbunden, und die Führungskulisse ist im Außenkörper angeordnet. Es ist sowohl möglich, dass die Verschiebung des Auftragsrohrs parallel zur Längsmittelachse durch die Endanschläge der Führungskulisse begrenzt wird, als auch dass das Auftragsrohr im Gehäuse um einen Verschiebeweg verschieblich ist, der kleiner ist als der in axialer Richtung gemessene Abstand der Endanschläge der Führungskulisse, so dass dieser Verschiebeweg die maximale Verschiebbarkeit des Auftragsrohrs definiert.According to a first embodiment, the inner body is received off-center in the outer body and rotatable with respect to the outer body, so that a rotation of a change in the eccentricity of the bearing portion the order tube causes. In this case, the eccentric expediently a twisting mechanism for rotating the inner body with respect to the outer body, which has a guided in a guide slot, radially projecting pins, wherein the guide slot substantially the shape a helical section. The pin is preferably guided in the guide slot between two end stops, which define two end positions of the inner body with respect to the outer body. The positive guidance of the journal in the helical section-shaped guide slot allows a conversion of a translational movement into a rotational movement. If the inner body is moved in the direction of the central longitudinal axis with respect to the outer body, a torsion of both bodies inevitably takes place, which causes a variation of the resulting eccentricity. This is particularly advantageous when the applicator tube is mounted axially displaceable axially immovable in the inner body and in the housing, so that over a displacement of the applicator tube in the direction of the longitudinal central axis, a rotation of the inner body with respect to the outer body can take place. In this case, according to a preferred embodiment, the pin is firmly connected to the inner body, and the guide slot is arranged in the outer body. It is both possible that the displacement of the applicator tube is limited parallel to the longitudinal center axis by the end stops of the guide link, as well as that the application tube is displaceable in the housing by a displacement which is smaller than the distance measured in the axial direction of the end stops of the guide link, so that this displacement defines the maximum displaceability of the order tube.

Zweckmäßig ist der Innenkörper gegenüber dem Außenkörper um eine Verdrehachse verdrehbar, deren Abstand zur Längsmittelachse gleich ihrem Abstand zur Mittelachse des Lagerabschnitts ist. Auf diese Weise lässt sich eine minimale resultierende Exzentrizität von Null einstellen.Suitably, the inner body relative to the outer body is rotatable about a rotation axis whose distance from the longitudinal central axis is equal to their distance from the central axis of the bearing portion. In this way, a minimum resulting eccentricity of zero can be set.

Gemäß einer zweiten Ausführungsform ist der Innenkörper in einer Richtung quer zur Längsmittelachse bezüglich des Außenkörpers linear verschieblich. Dabei ist es möglich, dass der Außenkörper einen in einem spitzen Winkel zur Längsmittelachse geneigten Führungskanal aufweist, in dem der Innenkörper aufgenommen ist. Eine Verschiebung des Innenkörpers im Führungskanal bewirkt dann eine Änderung der Exzentrizität. Diese Verschiebung kann wiederum dadurch erfolgen, dass das Auftragsrohr axial unverschieblich im Innenkörper und im Gehäuse begrenzt axial verschieblich gelagert ist. Gemäß einer alternativen Variante weist der Exzenter einen Verschiebemechanismus zum Verschieben des Innenkörpers bezüglich des Außenkörpers auf, der einen in einer Führungskulisse geführten, radial abstehenden Zapfen aufweist, wobei die Führungskulisse in einem spitzen Winkel gegenüber der Längsmittelachse geneigt ist. Die Führungskulisse kann dabei in einem parallel zur Längsmittelachse verschieblichen Schieber angeordnet sein, so dass dessen Verschiebung in axialer Richtung eine Verschiebung des Innenkörpers in radialer Richtung und somit eine Änderung der Exzentrizität bewirkt.According to a second embodiment, the inner body is linearly displaceable in a direction transverse to the longitudinal central axis with respect to the outer body. It is possible that the outer body has an inclined at an acute angle to the longitudinal central axis guide channel, in which the inner body is included. A displacement of the inner body in the guide channel then causes a change in the eccentricity. This shift can in turn take place in that the application tube is mounted axially displaceable axially immovable in the inner body and limited in the housing. According to an alternative variant, the eccentric on a displacement mechanism for moving the inner body with respect to the outer body, which has a guided in a guide slot, radially projecting pins, wherein the guide slot is inclined at an acute angle relative to the longitudinal central axis. The guide slot can be arranged in a parallel to the longitudinal central axis slidable slide, so that its displacement in the axial direction causes a displacement of the inner body in the radial direction and thus a change in the eccentricity.

Zweckmäßig ist eine um das Auftragsrohr umlaufende, sich ein Stück weit in der Längsrichtung des Auftragsrohrs erstreckende Ringnut vorgesehen, die in eine zum Auftragskanal führende Querbohrung mündet und in die der Materialzufuhranschluss mündet. Dies ermöglicht eine zuverlässige Zufuhr des Materials in das Gehäuse in den Auftragskanal auch dann, wenn das Auftragsrohr in seiner Längsrichtung verschoben wird. Zweckmäßig erstreckt sich die Ringnut über eine Länge des Auftragsrohrs, die größer ist als der Verschiebeweg, um den das Auftragsrohr verschieblich ist, insbesondere über eine Länge, die mindestens doppelt, vorzugsweise mindestens dreimal so groß ist wie der Verschiebeweg.It is expedient to provide an annular groove extending around the application tube and extending somewhat in the longitudinal direction of the application tube, which opens into a transverse bore leading to the application channel and into which the material supply connection opens. This allows a reliable supply of the material into the housing in the application channel even when the application tube is moved in its longitudinal direction. Suitably, the annular groove extends over a length of the applicator tube, which is greater than the displacement by which the applicator tube is displaceable, in particular over a length which is at least twice, preferably at least three times as large as the displacement.

Zur Reibungsminimierung ist das Drehlager zweckmäßig ein Kugellager. Es weist vorzugsweise einen fest mit dem Auftragsrohr verbundenen Innenring und einen fest mit dem Innenkörper verbundenen Außenring auf, zwischen denen die Kugeln angeordnet sind.To minimize friction, the pivot bearing is expediently a ball bearing. It preferably has a fixedly connected to the order pipe inner ring and a fixed to the inner body connected to the outer ring, between which the balls are arranged.

Gemäß einer vorteilhaften Weiterbildung ist zumindest ein Teil des Anfangsbereichs des Auftragsrohrs in einer verdrehfest im Gehäuse aufgenommenen Führungshülse aufgenommen und mit dieser fest verbunden. Dieser Teil des Auftragsrohrs wird beim Drehen des Exzenters dann nicht verformt. Das Auftragsrohr bzw. der betreffende Abschnitt des Auftragsrohrs bildet mit der Führungshülse eine Baueinheit, so dass die Fertigung vereinfacht wird. Dabei wird bevorzugt, dass sich die Führungshülse zumindest ein Stück weit entlang des Endbereichs erstreckt und zu diesem radial im Abstand angeordnet ist, so dass auch beim Drehen des Exzenters und der damit verbundenen Auslenkung des Auftragsrohrs keine Berührung zwischen der Führungshülse und dem Endbereich erfolgt. Zudem wird bevorzugt, dass sich der Innendurchmesser der Führungshülse in einem Übergangsbereich zwischen dem Anfangsbereich und dem Endbereich kontinuierlich vergrößert, um eine Kerbwirkung durch die Einspannung des Auftragsrohrs in der Führungshülse in diesem Bereich zu vermeiden.According to an advantageous development, at least part of the starting region of the application tube is received in a rotationally fixed manner in the housing Guide sleeve added and firmly connected to this. This part of the application tube is then not deformed when turning the eccentric. The application tube or the relevant section of the application tube forms a structural unit with the guide sleeve, so that the production is simplified. It is preferred that the guide sleeve extends at least a little way along the end region and is arranged radially spaced therefrom, so that even when rotating the eccentric and the associated deflection of the applicator tube no contact between the guide sleeve and the end region. In addition, it is preferred that the inner diameter of the guide sleeve increases continuously in a transition region between the starting region and the end region in order to avoid a notch effect due to the clamping of the application tube in the guide sleeve in this region.

Die in der Zeichnung dargestellte Vorrichtung 10 dient dem Auftragen eines viskosen Materials, beispielsweise eines Klebstoffs, auf ein Werkstück. Sie weist ein Gehäuse 12 auf, in dem ein einen Auftragskanal 14 für das viskose Material rings umschließendes Auftragsrohr 16 aufgenommen ist. Das Auftragsrohr 16 ist mehrstückig ausgebildet und erstreckt sich von einem eine Materialeintrittsöffnung 18 aufweisenden ersten Ende 20 bis zu einem durch eine Auftragsdüse 22 mit einer Materialaustrittsöffnung 24 gebildeten zweiten Ende 26. Das viskose Material wird über einen Materialzufuhranschluss 28 im Gehäuse 12 der Materialeintrittsöffnung 18 zugeführt. Das Auftragsrohr 16 weist einen vom ersten Ende 20 ausgehenden Anfangsbereich 30 auf, der mit dem Gehäuse 12 verbunden ist, sowie einen sich zum zweiten Ende 26 erstreckenden Endbereich 32, der im Abstand zum Gehäuse 12 angeordnet ist und über den größten Teil seiner Länge von einem Ringspalt 34 umgeben ist. Der Anfangsbereich 30 wird teilweise durch einen ersten Rohrabschnitt 36 gebildet, an den sich ein aus dem Gehäuse 12 ragender Fortsatz 38 anschließt. In der anderen Richtung schließt sich an den ersten Rohrabschnitt 36 ein elastisch biegsames Stahlrohr 40 an, das an seinem Ende die Auftragsdüse 22 trägt. In seinem zum Anfangsbereich 30 gehörenden Abschnitt ist das Stahlrohr 40 in einer verdrehfest im Gehäuse 12 aufgenommenen Führungshülse 42 aufgenommen. In einem zwischen dem Anfangsbereich 30 und dem Endbereich 32 angeordneten Übergangsbereich 44 vergrößert sich der Abstand zwischen der Führungshülse 42 und dem Stahlrohr 40 kontinuierlich, bis der Ringspalt 34 seine volle Breite erreicht. Der Anfangsbereich 30 definiert zudem eine mittig durch ihn verlaufende Längsmittelachse 46.The device 10 shown in the drawing is used for applying a viscous material, such as an adhesive, to a workpiece. It has a housing 12, in which a order duct 14 for the viscous material surrounding order tube 16 is received. The application tube 16 is formed in several pieces and extends from a first end 20 having a material inlet opening 18 to a second end 26 formed by an application nozzle 22 having a material outlet opening 24. The viscous material is supplied to the material inlet opening 18 via a material supply connection 28 in the housing 12. The applicator tube 16 has an outgoing from the first end 20 starting portion 30 which is connected to the housing 12, and extending to the second end 26 end portion 32 which is spaced from the housing 12 and over most of its length of a Annular gap 34 is surrounded. The initial region 30 is partially formed by a first pipe section 36, to which a protruding from the housing 12 extension 38 connects. In the other direction, adjoining the first pipe section 36 is an elastically flexible steel pipe 40, which carries the application nozzle 22 at its end. In its section belonging to the starting region 30, the steel tube 40 is accommodated in a guide sleeve 42 which is received in a rotationally fixed manner in the housing 12. In a transition region 44 arranged between the starting region 30 and the end region 32, the distance between the guide sleeve 42 and the steel tube 40 increases continuously until the annular gap 34 reaches its full width. The initial region 30 also defines a central longitudinal axis 46 extending centrally therethrough.

Das Auftragsrohr 16 weist in seinem Endbereich 32 einen Lagerabschnitt 48 auf, der in einem um die Längsmittelachse 46 drehbar im Gehäuse 12 angeordneten und motorisch antreibbaren Exzenter 50 gelagert ist. Der Exzenter 50 weist einen Außenkörper 52 auf, in dem außermittig ein Innenkörper 54 aufgenommen ist, in welchem wiederum mittels eines als Kugellager ausgebildeten Drehlagers 56 der Lagerabschnitt 48 gelagert ist. Das Kugellager 56 weist einen fest mit dem Lagerabschnitt 48 verbundenen Innenring 58, einen fest mit dem Innenkörper 54 verbundenen Außenring 60 und zwischen dem Innenring 58 und dem Außenring 60 angeordnete Kugeln 62 auf.The applicator tube 16 has in its end region 32 on a bearing portion 48 which is rotatably mounted in a housing about the longitudinal center axis 46 in the housing 12 and rotatably driven eccentric 50 is mounted. The eccentric 50 has an outer body 52, in which eccentrically an inner body 54 is received, in which in turn by means of a ball bearing designed as a pivot bearing 56 of the bearing portion 48 is mounted. The ball bearing 56 has an integral with the bearing portion 48 inner ring 58, a fixedly connected to the inner body 54 outer ring 60 and disposed between the inner ring 58 and the outer ring 60 balls 62.

Durch Verdrehen des Innenkörpers 54 gegenüber dem Außenkörper 52 wird der Lagerabschnitt 48 zwischen einer in Fig. 1, 2a, 2b dargestellten minimal exzentrischen Stellung und einer in Fig. 3a, 3b dargestellten maximal exzentrischen Stellung bewegt, wobei das Stahlrohr 40 verbogen wird. In der minimal exzentrischen Stellung weist der Lagerabschnitt 48 im hier gezeigten Ausführungsbeispiel eine Exzentrizität von Null auf, so dass die Längsmittelachse 46 auch die Mittelachse des Endbereichs 32 bildet. Je größer die durch den Außenkörper 52 und den Innenkörper 54 vorgegebene resultierende Exzentrizität des Lagerabschnitts 48 ist, desto stärker ist die Mittelachse des Endbereichs 32 gebogen. Die größte Abweichung von der Längsmittelachse 46 befindet sich an der Materialaustrittsöffnung 24. Eine Drehung des Exzenters 50 um die Längsmittelachse 46 durch Beaufschlagung des Außenkörpers 52 durch einen Elektromotor 64 mit einer typischen Drehzahl von mehreren tausend Umdrehungen pro Minute führt, abhängig von der eingestellten Exzentrizität des Lagerabschnitts 48, zu einer Bewegung der Materialaustrittsöffnung 24 auf einer Kreisbahn, so dass das aus dieser austretende viskose Material aufgrund von Fliehkräften verwirbelt wird und über eine wesentlich größere Breite verteilt wird, als dies ohne Rotation des Exzenters 50 bzw. bei einer Exzentrizität des Lagerabschnitts 48 von Null der Fall wäre. Die kreisförmige Bewegung des viskosen Materials, und damit die Auftragsbreite, ist umso größer, je größer die resultierende Exzentrizität des Lagerabschnitts 48 ist.By rotating the inner body 54 relative to the outer body 52 of the bearing portion 48 between a in Fig. 1 . 2a, 2b shown minimal eccentric position and a in Fig. 3a, 3b moves shown maximum eccentric position, wherein the steel tube 40 is bent. In the minimal eccentric position, the bearing section 48 in the embodiment shown here has an eccentricity of zero, so that the longitudinal central axis 46 also forms the central axis of the end region 32. The larger the resultant eccentricity of the bearing portion 48 given by the outer body 52 and the inner body 54, the more the central axis of the end portion 32 is bent. The greatest deviation from the longitudinal central axis 46 is located at the material outlet opening 24. A rotation of the eccentric 50 about the longitudinal central axis 46 by applying the outer body 52 by an electric motor 64 at a typical speed of several thousand revolutions per minute, depending on the set eccentricity of Bearing portion 48, a movement of the material outlet opening 24 on a circular path, so that the exiting from this viscous material is swirled due to centrifugal forces and is distributed over a substantially larger width than this without rotation of the eccentric 50 and an eccentricity of the bearing portion 48th zero would be the case. The circular movement of the viscous material, and thus the application width, is greater, the greater the resulting eccentricity of the bearing portion 48.

Zur Einstellung der Exzentrizität ist der Innenkörper 54 mit einem radial abstehenden Zapfen 66 versehen, der in eine wendelförmige Führungskulisse 68 im Außenkörper 52 eingreift. Das Auftragsrohr 16 ist zudem zum einen in Richtung der Längsmittelachse 46 längsverschieblich im Gehäuse 12 angeordnet, zum anderen in axialer Richtung unverschieblich im Innenkörper 54 aufgenommen. Eine Verschiebung des Auftragsrohrs 16 im Gehäuse 12, die im vorliegenden Ausführungsbeispiel durch Drehen am Fortsatz 38 aufgrund eines Schraubgetriebes 70 erzielt wird, nimmt den Innenkörper 54 in axialer Richtung mit, wobei aufgrund der Führung des Zapfens 66 in der Führungskulisse 68 zudem eine Verdrehung des Innenkörpers 54 gegenüber dem Außenkörper 52 erfolgt. Auf diese Weise ist die resultierende Exzentrizität des Lagerabschnitts 48 leicht manuell einstellbar. Es versteht sich von selbst, dass eine solche Einstellung auch mittels eines motorischen Antriebs erfolgen kann.To adjust the eccentricity of the inner body 54 is provided with a radially projecting pin 66 which engages in a helical guide slot 68 in the outer body 52. The applicator tube 16 is also arranged longitudinally displaceable in the housing 12 in the direction of the longitudinal center axis 46, on the other hand in the axial direction immovably in the inner body 54th added. A displacement of the application tube 16 in the housing 12, which is achieved in the present embodiment by turning the extension 38 due to a helical gear 70, takes the inner body 54 in the axial direction, wherein due to the guidance of the pin 66 in the guide slot 68 also a rotation of the inner body 54 takes place with respect to the outer body 52. In this way, the resulting eccentricity of the bearing portion 48 is easily manually adjustable. It goes without saying that such a setting can also be done by means of a motor drive.

Um das viskose Material zuverlässig über den Materialzufuhranschluss 28 in den Auftragskanal 14 einleiten zu können, ist das Auftragsrohr 16 im Bereich des Materialzufuhranschlusses 28 mit einer umlaufenden Ringnut 72 versehen, die sich ein Stück weit in axialer Richtung erstreckt. Die Ringnut 72 mündet in eine Querbohrung 74, die zur Materialeintrittsöffnung 18 führt.In order to be able to reliably introduce the viscous material into the application channel 14 via the material supply connection 28, the application tube 16 in the region of the material supply connection 28 is provided with a circumferential annular groove 72 which extends somewhat in the axial direction. The annular groove 72 opens into a transverse bore 74, which leads to the material inlet opening 18.

Die Auftragsvorrichtungen gemäß dem zweiten, dritten und vierten Ausführungsbeispiel sind in Fig. 4 bis 6 lediglich in einer Detaildarstellung und noch weiter schematisiert dargestellt als die Auftragsvorrichtung 10 gemäß dem ersten Ausführungsbeispiel. Gleiche Merkmale sind mit gleichen Bezugszeichen versehen.The application devices according to the second, third and fourth embodiments are in 4 to 6 only in a detailed representation and shown further schematically as the application device 10 according to the first embodiment. Same features are provided with the same reference numerals.

Das in Fig. 4 dargestellte zweite Ausführungsbeispiel unterscheidet sich vom ersten Ausführungsbeispiel gemäß Fig. 1 bis 3 im wesentlichen dadurch, dass der Innenkörper 54 axial unverschieblich angeordnet ist, während der Außenkörper 52 in axialer Richtung verschieblich angeordnet ist. Vom Innenkörper 54 steht ein Zapfen 66 radial vor, welcher in einer wendelförmig verlaufenden Führungskulisse 68 im Außenkörper 52 aufgenommen ist. Beim zweiten Ausführungsbeispiel führt somit eine axiale Verschiebung des Außenkörpers 52 zu einer Verdrehung des außermittig in ihm aufgenommenen Innenkörpers 54, in dem wiederum der in Fig. 4 nicht im Detail dargestellte Lagerabschnitt 48 des Auftragsrohrs 16 aufgenommen ist. Die Drehung des Exzenters 50 wird durch eine den Außenkörper 52 abschnittsweise rings umschließende Rotorwelle 80 übertragen, die mit einer inneren Welle 82 verbunden ist, auf der auf einem Absatz 84 der Innenkörper 54 ruht.This in Fig. 4 illustrated second embodiment differs from the first embodiment according to Fig. 1 to 3 essentially in that the inner body 54 is arranged axially non-displaceable, while the outer body 52 is arranged displaceably in the axial direction. From the inner body 54 is a pin 66 radially in front, which is received in a helically extending guide slot 68 in the outer body 52. In the second embodiment, thus, an axial displacement of the outer body 52 leads to a rotation of the eccentrically received in it inner body 54, in which in turn the in Fig. 4 not shown in detail bearing portion 48 of the applicator tube 16 is added. The rotation of the The eccentric 50 is transmitted by a rotor shaft 80 surrounding the outer body 52 in sections, which is connected to an inner shaft 82 on which the inner body 54 rests on a shoulder 84.

Beim dritten Ausführungsbeispiel (Fig. 5) ist der Innenkörper 54 nicht gegenüber dem Außenkörper 52 verdrehbar, sondern in radialer Richtung verschieblich. Auch beim dritten Ausführungsbeispiel ist der Außenkörper 52 als in axialer Richtung verschieblicher Schieber ausgebildet, welcher zwei einander diametral gegenüberliegende, radial nach innen vorstehende, in Fig. 5 nicht im Detail gezeigte Zapfen aufweist, welche in Führungskulissen im Innenkörper 54 eingreifen. Die Führungskulissen sind gegenüber der Längsmittelachse 46 in einem spitzen Winkel angeordnet, so dass ein Verschieben der Zapfen in axialer Richtung eine Verschiebung des Innenkörpers 54 bewirkt. Wie schon beim zweiten Ausführungsbeispiel wird die Drehbewegung über eine den Außenkörper 52 aufnehmende Rotorwelle 80 auf den Exzenter übertragen, welche mit einer inneren Welle 82 verbunden ist. Auf einem Absatz 84 der inneren Welle 82 ruht der Innenkörper 54.In the third embodiment ( Fig. 5 ), the inner body 54 is not rotatable relative to the outer body 52, but slidable in the radial direction. Also in the third embodiment, the outer body 52 is formed as a slidable in the axial direction slide, which two diametrically opposed, radially inwardly projecting, in Fig. 5 not shown in detail pin, which engage in guide slots in the inner body 54. The guide slots are arranged at an acute angle relative to the longitudinal center axis 46, so that a displacement of the pins in the axial direction causes a displacement of the inner body 54. As in the second embodiment, the rotational movement is transmitted via a rotor shaft 80 receiving the outer body 52 to the eccentric, which is connected to an inner shaft 82. On a shoulder 84 of the inner shaft 82, the inner body 54 rests.

Auch beim vierten Ausführungsbeispiel (Fig. 6) ist der Innenkörper 54 gegenüber dem Außenkörper 52 verschieblich. Der Außenkörper 52, der gleichzeitig die Rotorwelle 80 darstellt, ist mit einem Führungskanal 86 versehen, dessen Mittelachse 88 um einen spitzen Winkel β gegenüber der Längsmittelachse 46 geneigt ist. Der Führungskanal 86 verläuft in Fig. 5 schräg von rechts oben nach links unten. In ihm ist der Innenkörper 54 aufgenommen, welcher wiederum verschiebefest mit dem Auftragsrohr 16 verbunden ist. Eine Bewegung des Auftragsrohrs 16 in axialer Richtung resultiert somit in einer Bewegung des Innenkörpers 54 in axialer Richtung und in einer Verschiebung des Innenkörpers 54 im Führungskanal 86, an dessen Innenwand 90 der Innenkörper 54 mit einer balligen Kontaktfläche 92 anliegt.Also in the fourth embodiment ( Fig. 6 ), the inner body 54 is displaceable relative to the outer body 52. The outer body 52, which simultaneously represents the rotor shaft 80, is provided with a guide channel 86 whose center axis 88 is inclined at an acute angle β with respect to the longitudinal central axis 46. The guide channel 86 extends in Fig. 5 diagonally from top right to bottom left. In it, the inner body 54 is received, which in turn is non-displaceably connected to the applicator tube 16. A movement of the applicator tube 16 in the axial direction thus results in a movement of the inner body 54 in the axial direction and a displacement of the inner body 54 in the guide channel 86, against the inner wall 54 of the inner body 54 abuts with a spherical contact surface 92.
