Derartige Stellkörper werden in Vorrichtungen zum fließfähigen Auftragen eines Heißschmelzklebemittels auf eine Materialbahn eingesetzt. Eine derartiger Stellkörper ist aus EP-B-1 181 105 bekannt. Diese Vorrichtung umfasst einen Beschichtungskopf mit einer Schlitzdüsenanordnung um das Klebemittel auszutragen. In dem Beschichtungskopf ist ein zentraler Verteilerkanal vorgesehen, durch welchen das Klebemittel über einen Dosierspalt einer Schlitzdüsenanordnung zugeführt wird. Zur Einstellung der Arbeitsbreite der Schlitzdüsenanordnung ist in dem Verteilerkanal zumindest ein Stellkörper vorgesehen, welcher zumindest radial in dem Verteilerkanal verdrehbar angeordnet ist. In dem Stellkörper sind Langlochbohrungen axial zueinander beabstandet vorgesehen, welche in Abhängigkeit der Drehung eine unterschiedliche Größe des Durchgangs zwischen dem Verteilerkanal und dem Dosierspalt bilden. Dadurch kann die Menge des Klebemittels bestimmt werden, welche zur Schlitzdüsenanordnung gelangt.Such adjusting bodies are used in devices for the flowable application of a hot melt adhesive to a material web. Such a control body is made EP-B-1 181 105 known. This device comprises a coating head having a slot nozzle arrangement for discharging the adhesive.

Die Pumpeneinheit 29 kann Dosierpumpen umfassen als auch einen Puffertank, ein Schmelzaggregat oder ähnliches, um das fließfähige Medium in geeigneter Weise bereitzustellen und dem Zuführkanal 28 zuzuführen. Der Zuführkanal 28 mündet in einen Verteilerkanal 31, der sich vorzugsweise parallel zur Schlitzdüsenanordnung 19 über die gesamte Breite des Gehäuseabschnitts 21 erstreckt. Von dem Verteilerkanal 31 führen Versorgungskanäle 32 in einen Dosierspalt 34, welcher bspw. in der Trennebene 23 liegt. In dem Dosierspalt 34 ist eine Schablone 36 angeordnet, welche segmentförmige Kanäle 37 aufweist. Diese segmentförmigen Kanäle 37 sind beispielsweise kelch-, V-, oder U-förmig ausgebildet. Die Versorgungskanäle 32 münden vorzugsweise vollständig in die segmentförmigen Kanäle 37. In Abhängigkeit des zu verarbeitenden fließfähigen Mediums kann die Schablone 36 in der Dicke und Geometrie entsprechend ausgebildet sein, um eine gewünschte Masse an fließfähigem Medium aufzutragen. Die Schablone 36 ist austauschbar in dem Dosierspalt 34 angeordnet. Der Dosierspalt 34 weist an seinem äußeren Ende eine obere und untere Austraglippe 38, 39 auf und bildet eine sogenannte Abquetschfläche und führt gleichzeitig das Bahnmaterial an deren Außenseite tangential entlang.The device 11 is a so-called coating head which has a nozzle arrangement 19, in particular a slot die arrangement. The device 11 consists of a first and second or upper and lower housing portion 21, 22, wherein the upper housing portion 21 advantageously along a parting plane 23 of the lower housing portion 22, preferably for cleaning, is removable. In the housing sections 21, 22 bores 24 are provided, in which controllable heating elements are arranged. In the upper housing portion 21, a feed channel 28 is provided, to which a pump unit 29 is connected. About this pump unit 29, the flowable medium of the device 11 is supplied.

The feed channel 28 opens into a distributor channel 31, which extends preferably parallel to the slot nozzle arrangement 19 over the entire width of the housing section 21. From the distribution channel 31 lead supply channels 32 in a metering gap 34, which is, for example, in the parting plane 23. In the metering gap 34, a template 36 is arranged, which has segment-shaped channels 37. These segment-shaped channels 37 are formed, for example, kelch-, V-, or U-shaped. The supply channels 32 preferably open completely into the segment-shaped channels 37. Depending on the flowable medium to be processed, the template 36 may be formed in thickness and geometry to apply a desired mass of flowable medium. The template 36 is arranged interchangeably in the metering gap 34. The metering gap 34 has at its outer end to an upper and lower discharge lip 38, 39 and forms a so-called Abquetschfläche and simultaneously guides the web material on the outside tangentially along.

Im unteren Gehäuseabschnitt 22 sind Bohrungen 41 zur Aufnahme von Ventilen 42 vorgesehen, welche zur Regelung der Durchflussmenge des Mediums vom Versorgungskanal 32 in den segmentförmigen Kanal 37 dienen. Die Ventile 42 weisen eine einstellbare Nadel 43 mit einer kegeligen oder konischen Spitze auf, die in dem Versorgungskanal 32 positionierbar ist. Durch die variable Einstellung der Ventile 42 wird eine für alle Versorgungskanäle 32 gleiche Durchflussmenge als Grundeinstellung ermöglicht. Alternativ kann vorgesehen sein, dass diese Ventile 42 eine zusätzliche Zu- und Abschaltung für die Verstellung einer Arbeitsbreite eines Dosierspaltes 34 einsetzbar und ebenfalls ansteuerbar sind.In the lower housing portion 22 bores 41 are provided for receiving valves 42, which serve to regulate the flow rate of the medium from the supply channel 32 in the segment-shaped channel 37. The valves 42 have an adjustable needle 43 with a tapered or conical tip that is positionable in the supply channel 32. Due to the variable setting of the valves 42, a flow rate that is the same for all supply channels 32 is made possible as a basic setting.

In dem Verteilerkanal 31 ist ein Stellkörper 46 einer Einstelleinheit 47 angeordnet, der axial und/oder radial in dem Verteilerkanal 31 bewegbar ist. Der Stellkörper 46 ist rohrförmig ausgebildet und weist ein offenes Ende zur Mitte der Düsenanordnung 19 auf. Zum äußeren Randbereich des Gehäuseabschnitts 21 ist der Stellkörper durch eine Verschlusselement 48 oder ein Verschlussstopfen geschlossen.In the distribution channel 31, a setting member 46 of a setting unit 47 is arranged, which is axially and / or radially movable in the distribution channel 31. The adjusting body 46 is tubular and has an open end to the center of the nozzle assembly 19. To the outer edge region of the housing portion 21 of the actuating body is closed by a closure element 48 or a sealing plug.

In Figur 2 ist der Stellkörper 46 schematisch dargestellt. An einem linken Ende ist ein Flansch 51 und eine Aufnahme 52 vorgesehen, durch welche der Stellkörper 46 auswechselbar über die Einstelleinheit 47 aufgenommen und angesteuert wird. Benachbart zum Flansch 51 ist eine Bohrung 53 vorgesehen, welche als Einstellhilfe zur exakten radialen Ausrichtung des Stellkörpers 46 in dem Verteilerkanal 31 bzw. den Versorgungskanälen 32 ermöglicht. Ein in den Verteilerkanal 31 eintauchender Abschnitt umfasst eine Vielzahl von Hülsenabschnitten 54 und Ringabschnitte 56, welche gemäß dem Ausführungsbeispiel in Figur 2 abwechselnd zueinander auf dem zylindrischen Hohlkörper 58 angeordnet sind. Der Stellkörper 46 weist dem äußeren Gehäuseabschnitt 22 zugeordnet einen ersten Hülsenabschnitt 54 auf, der eine Durchgangsbohrung 59 umfasst, welche einen Durchgang 61 zwischen dem Verteilerkanal 31 bzw. des Innenraumes des Hohlkörpers 58 und einem Versorgungskanal 32 bildet. An den ersten Hülsenabschnitt 54 angrenzend ist ein Ringabschnitt 56 vorgesehen. Dieser Ringabschnitt 56 ist im Außendurchmesser kleiner als der Hülsenabschnitt 54 ausgebildet. An diesen Ringabschnitt 56 schließt sich wiederum ein zweiter Hülsenabschnitt 54 an, der bspw. zwei Durchgangsbohrungen 59 umfasst. Die erste Durchgangsbohrung 59 des zweiten Hülsenabschnitts 54 ist auf einer ersten radialen Position 66 angeordnet. Die zweite Durchgangsbohrung 59 des zweiten Hülsenabschnitts 54 ist auf einer radialen Position 67 angeordnet. Eine dritte Durchgangsbohrung 59 am dritten Hülsenabschnitt 54 ist an einer dritten radialen Position 68 angeordnet usw. Dadurch wird ermöglicht, dass in einer Einstellung, bei der die radiale Ausrichtung 66 mit den Verteilerkanälen 32 fluchtet, ein maximaler Austrag bzw. eine maximale Zuführung von Klebemittel zum Dosierspalt 34 erfolgt. Durch das Verdrehen des Stellkörpers 46 kann eine stufenweise Einstellung ermöglicht sein, wobei von außen nach innen die Auftragsbreite des Klebemittels durch die einstellbare radiale Position des Stellkörpers 46 abnimmt. Eine weitere Position ist auch eine Schließstellung, in welcher die Durchgänge 61 geschlossen sind und kein Klebemittel den Verteilerkanälen 32 zugeführt wird.In Figure 2, the actuator 46 is shown schematically. At a left end, a flange 51 and a receptacle 52 is provided, through which the adjusting body 46 is exchangeably received and controlled via the setting unit 47. Adjacent to the flange 51 is a bore 53 is provided, which allows as adjustment for the exact radial alignment of the actuating body 46 in the distribution channel 31 and the supply channels 32. A dipping into the distribution channel 31 section comprises a plurality of sleeve portions 54 and ring portions 56 which are arranged according to the embodiment in Figure 2 alternately to each other on the cylindrical hollow body 58. The adjusting body 46 has the outer housing portion 22 associated with a first sleeve portion 54 which comprises a through hole 59 which forms a passage 61 between the manifold 31 and the interior of the hollow body 58 and a supply channel 32. Adjacent to the first sleeve portion 54, a ring portion 56 is provided. This ring portion 56 is smaller in outer diameter than the sleeve portion 54 is formed. A second sleeve section 54 in turn adjoins this annular section 56, which, for example, comprises two through-holes 59. The first through hole 59 of the second sleeve portion 54 is disposed at a first radial position 66. The second through-hole 59 of the second sleeve portion 54 is arranged at a radial position 67. A third through-hole 59 on the third sleeve portion 54 is disposed at a third radial position 68, etc. This allows a maximum discharge of adhesive to be achieved in a setting where the radial orientation 66 is aligned with the manifold channels 32 Dosing 34 takes place. By rotating the adjusting body 46, a stepwise adjustment may be made possible, wherein the application width of the adhesive decreases from outside to inside by the adjustable radial position of the adjusting body 46. Another position is also a closed position in which the passages 61 are closed and no adhesive is supplied to the distribution channels 32.

Die Anordnung der Durchgangsbohrungen 59.ist bspw. in Figur 3 dargestellt, welches einer Schnittdarstellung entlang der Linie II-II in Figur 2 entspricht. Die erste Durchgangbohrung 59 verläuft im Wesentlichen tangential zum Innenraum des Hohlkörpers 58. Die zweite Durchgangsbohrung 59 ist winklig zur ersten Durchgangsbohrung 59 angeordnet, so das innerhalb der Wandstärke des Hohlkörpers 38 die Bohrungen sich zumindest teilweise schneiden oder aneinander angrenzen. Die weiteren vorgesehenen Durchgangsbohrung 59 sind analog ausgebildet.The arrangement of the through-holes 59 is illustrated, for example, in FIG. 3, which corresponds to a sectional view along the line II - II in FIG. The first through hole 59 extends substantially tangentially to the interior of the hollow body 58. The second through hole 59 is arranged at an angle to the first through hole 59, so that within the wall thickness of the hollow body 38, the holes at least partially cut or adjacent to each other. The further provided through-hole 59 are formed analogously.

Der Hülsenabschnitt 54 wird zur Positionierung auf dem Hohlkörper 58 erwärmt, so dass der Innendurchmesser des Hülsenabschnittes 54 gegenüber dem Außendurchmesser des Hohlkörpers 58 vergrößert ist.
Nach dem Abkühlen ist der Hülsenabschnitt 54 bevorzugt über eine Presspassung oder einen Presssitz auf dem Hohlkörper.58 befestigt.The sleeve portion 54 is heated for positioning on the hollow body 58, so that the inner diameter of the sleeve portion 54 relative to the outer diameter of the hollow body 58 is increased.
After cooling, the sleeve portion 54 is preferably fixed to the hollow body 58 via a press fit or an interference fit.

Zur Erhöhung der Haftung zwischen dem Hülsenabschnitt 54, dem Ringabschnitt 54 und/oder der Baugruppe 64 und dem Hohlkörper 58 kann eine Rändelung auf dem Hohlkörper 58 aufgebracht sein. Des weiteren kann eine entlang der Längsachse verlaufende Riffelung oder eine rautenförmige Riffelung oder dergleichen aufgebracht werden. Ebenso kann vorgesehen sein, dass ein hitzebeständiges Klebemittel zwischen dem Hülsenabschnitt 54 und dem Hohlkörper 58 eingebracht wird, um den Presssitz zu sichern.To increase the adhesion between the sleeve portion 54, the ring portion 54 and / or the assembly 64 and the hollow body 58, a knurling on the hollow body 58 may be applied. Furthermore, a corrugation running along the longitudinal axis or a diamond-shaped corrugation or the like can be applied. It can also be provided that a heat-resistant adhesive is introduced between the sleeve portion 54 and the hollow body 58 in order to secure the interference fit.

Der Hülsenabschnitt 54 ist gemäß einer ersten vorteilhaften Ausführungsform als ringförmiges Element ausgebildet, welches zumindest geringfügig breiter als der Durchmesser einer Durchgangsbohrung 59 ausgebildet ist. Der Ringabschnitt 56 ist ebenfalls als Einzelelement ringförmig ausgebildet und kann in Analogie zum Hülsenabschnitt 54 auf dem zylindrischen Hohlkörper 58 fixiert sein. Der Ringabschnitt 56 dient im Wesentlichen zur Beabstandung von zwei zueinander angeordneten Hülsenabschnitten 54. Der verringerte Außendurchmesser des Ringabschnitts 56 gegenüber dem des Hülsenabschnitts 54 ermöglicht eine Reduzierung in der Antriebskraft durch eine verringerte Reibfläche. Der zumindest eine Ringabschnitt 56 kann wahlweise zwischen zwei Hülsenabschnitten 54 vorgesehen sein.The sleeve portion 54 is formed according to a first advantageous embodiment as an annular element which is at least slightly wider than the diameter of a through hole 59 is formed. The ring portion 56 is also annular as a single element and may be fixed in analogy to the sleeve portion 54 on the cylindrical hollow body 58. The annular portion 56 substantially serves to space two mutually spaced sleeve portions 54. The reduced outer diameter of the annular portion 56 from that of the sleeve portion 54 allows for a reduction in driving force due to a reduced friction surface. The at least one annular section 56 may optionally be provided between two sleeve sections 54.

Nach einer vorteilhaften Ausführungsform ist vorgesehen, dass eine Baugruppe 64 gebildet ist, welche mehrere Hülsenabschnitt 54 und Ringabschnitte 56 umfasst. Im Ausführungsbeispiel gemäß Figur 2 sind zwei Baugruppen 64 dargestellt, wobei die beiden Baugruppen 64 in deren Übergangsbereich durch eine Dehnfuge 69 oder ein Abstand 69 zueinander angeordnet sind. Die Baugruppe 64 ist als zylindrischer Körper ausgebildet. Durch eine Drehbearbeitung können die Außendurchmesser der Hülsenabschnitte 54 und der Ringabschnitte 56 als auch die Breite der Hülsenabschnitte 54 und Ringabschnitte 56 festgelegt sein. Die Breite der Ringabschnitte 56 ist abhängig von dem Abstand der Verteilerkanäle 32 und der Größe der Verteilerkanäle 32. Der Hülsenabschnitt 54 umgibt die Durchgangsbohrung 59 vollständig, wobei die Durchgangsbohrung 59 kleiner oder gleich groß zum Durchmesser des Verteilerkanals 32 ausgebildet ist.According to an advantageous embodiment it is provided that an assembly 64 is formed, which comprises a plurality of sleeve portion 54 and ring portions 56. In the embodiment shown in Figure 2, two assemblies 64 are shown, wherein the two assemblies 64 in the transition region by an expansion joint 69 or a distance 69 to each other are arranged. The assembly 64 is formed as a cylindrical body. By turning, the outer diameter of the sleeve portions 54 and the ring portions 56 and the width of the sleeve portions 54 and ring portions 56 may be fixed. The width of the ring portions 56 is dependent on the distance of the distribution channels 32 and the size of the distribution channels 32. The sleeve portion 54 surrounds the through hole 59 completely, wherein the through hole 59 is smaller or equal to the diameter of the distribution channel 32 is formed.

Der Außendurchmesser des Hülsenabschnittes 54 ist an die Größe des Verteilerkanals 31 angepasst, so dass eine Rotation zur Einstellung des Stellkörpers 46 ermöglicht ist, jedoch gleichzeitig eine abdichtenden Anordnung zwischen der Durchgangsbohrung 51 und des daran angrenzenden Wandabschnittes des Verteilerkanals 31 vorgesehen ist.The outer diameter of the sleeve portion 54 is adapted to the size of the distribution channel 31, so that a rotation for adjusting the actuator 46 is allowed, but at the same time a sealing arrangement between the through hole 51 and the adjoining wall portion of the distribution channel 31 is provided.

Die Durchgangsbohrungen 59 werden bei der in Figur 2 dargestellten Ausführungsform bevorzugt nach dem Aufbringen der Baugruppe 64 oder einzelnen Hülsenabschnitte 54 und Ringabschnitte 56 und dazwischen angeordneten Ringabschnitten 56 eingebracht.In the embodiment illustrated in FIG. 2, the through-holes 59 are preferably introduced after the application of the assembly 64 or individual sleeve sections 54 and ring sections 56 and ring sections 56 arranged therebetween.

Nach einer alternativen Ausgestaltung der Erfindung kann vorgesehen sein, dass in den Verteilerkanal 31 ein Körper eingesetzt wird, welcher einer Baugruppe 64 entspricht. Dieser Körper wird bspw. in einem stark abgekühlten Zustand in den Verteilerkanal 31 eingesetzt und bildet eine Presspassung zum Verteilerkanal 31. Der Stellkörper 46 ist als Hohlkörper 58 ausgebildet und wird in die eingesetzte und im Verteilerkanal eingepresste Baugruppe 64 eingesetzt und geführt. Dadurch kann die vorbeschriebene Wirkung erzielt werden, wonach zumindest ein Antrieb mit geringen Reibkräften gegeben ist und Durchgangsbohrung 59 in einer Nichtgebrauchsposition den oder die Durchgänge 61 dicht verschließen.According to an alternative embodiment of the invention can be provided that in the distribution channel 31, a body is used, which corresponds to an assembly 64. This body is used, for example, in a strongly cooled state in the distribution channel 31 and forms a press fit to the distribution channel 31. The adjusting body 46 is formed as a hollow body 58 and is inserted into the inserted and pressed-in the distribution channel assembly 64 and guided. Thereby, the above-described effect can be achieved, according to which at least one drive is given with low frictional forces and through hole 59 in a non-use position or close the passages 61 tight.
