Abstract

In a multi-ply headbox of a papermaking machine, a flexible partition foil or sheet is connected by an apparatus to a rigid partition element dividing the nozzle chamber. For rapid replacement of the flexible partition foil or sheet, the apparatus comprises an upper retaining strip and a lower retaining strip which are structured for force-locking or form-closed or form-locking clamping of the flexible partition foil or sheet therebetween and secured at the rigid partition element. Between the upper and lower retaining strips there is provided a pressure chamber of a pressure device, which pressure chamber can be impinged by a pressurized fluid medium for spreading or expanding, if necessary, the upper and the lower retaining strips. The pressure chamber possesses the shape of a continuous groove extending across the entire outlet width of the headbox. This groove is lined with an elastic sealing coating or lining and the space bounded by such elastic sealing coating is connected via lines or conduits to a pressurized fluid medium source.

Description

Die Erfindung betrifft eine Vorrichtung zum Halten einer Trennlamelle am Mehrschicht-Stoffauflauf einer Papiermaschine, welche Trennlamelle an einem einen Düsenraum des Stoffauflaufes teilenden Trennelement befestigt ist und zum weiteren Getrennthalten der Stoffschichten über eine Strecke in Laufrichtung der Papiermaschine dient, wobei die Vorrichtung eine obere und eine untere Halteleiste aufweist, die zum Einklemmen oder Einschließen eines Teils der Trennlamelle zwischen ihnen ausgebildet sind.The invention relates to a device for holding a separating lamella on the multi-layer headbox of a paper machine, which separating lamella is fastened to a separating element which divides a nozzle space of the headbox and is used for further keeping the layers of material separate over a distance in the running direction of the paper machine, the device having an upper and a has lower retaining strip which are designed for clamping or enclosing a part of the separating lamella between them.

Die Trennlamelle ist aus einem flexiblen Material und ist am Trennelement an seiner in Auslaufrichtung weisenden Spitze an einer Verbindungsstelle mittels einer Vorrichtung montiert. Zum An- bzw. Abbauen der Trennlamelle ist eine relativ umständliche und zeitaufwendige Montage notwendig. Dies ist beim Wechseln der Trennlamelle bei wechselnden Anforderungen an die Länge der Trennlamelle, in Auslaufrichtung gesehen, zur Anpassung an verschiedene Arbeitsaufgaben der Papiermaschine oder nach Verschleiß der Trennlamelle bei Wartung notwendig. Eine bekannte Anordnung der Trennlamelle ist z.B. in der DE-PS 32 27 218 gezeigt.The separating lamella is made of a flexible material and is mounted on the separating element at its point pointing in the outlet direction at a connection point by means of a device. A relatively cumbersome and time-consuming assembly is necessary to attach or remove the separating lamella. This is necessary when changing the separating lamella with changing demands on the length of the separating lamella, viewed in the outlet direction, to adapt to various work tasks of the paper machine or after wear of the separating lamella during maintenance. A known arrangement of the separating lamella is e.g. shown in DE-PS 32 27 218.

In einer weiteren Ausführung gemäß GB-A-2 187 485 ist ein Stoffauflauf beschrieben, der eine Trennwand zur Ermöglichung der Mehrlagigkeit aufweist. Diese Trennwand ist allerdings mit den Seitenwänden des Stoffauflaufes starr verbunden. Zur Verbindung dieser Teile dient in einer speziellen Ausführungsform ein durch einen elastisch verformbaren Druckraum verspannbarer Bajonettverschluß. Diese Ausführung ist jedoch aufwendig zu bauen und zu betätigen und läßt nur eine Winkelstellung zu. Während des Stoffauflaufbetriebes ist ständiger Druck im besagten Druckraum erforderlich.In a further embodiment according to GB-A-2 187 485, a headbox is described which has a partition to enable the multilayer. However, this partition is rigidly connected to the side walls of the headbox. In a special embodiment, a bayonet lock that can be braced by an elastically deformable pressure chamber is used to connect these parts. However, this version is complex to build and operate and only allows an angular position. Constant pressure in said pressure chamber is required during headbox operation.

Ziel der Erfindung ist es, einen schnellen Wechsel der Trennlamelle ohne eine umständliche und zeitaufwendige Montage zu ermöglichen.The aim of the invention is to enable a quick change of the separating lamella without a complicated and time-consuming assembly.

Zur Erfüllung dieser Aufgabe sind an der erfindungsgemäßen Vorrichtung die beiden Halteleisten an dem Trennelement befestigt, wobei zwischen den Halteleisten eine mit einem Druckmedium beaufschlagbare Druckkammer einer Druckvorrichtung vorgesehen ist, wodurch die Halteleisten relativ zueinander spreizbar sind. Durch Aufbringen eines Druckes in der Druckkammer der Druckvorrichtung klaffen die Halteleisten auseinander und lassen zwischen sich einen Raum frei, der zum An- oder Abbauen der Trennlamelle zwischen den Halteleisten notwendig ist. Nach dem Absenken des Druckes in der Druckkammer kommen die Halteleisten aneinander zum Anliegen, wodurch das Festhalten der eingesetzten Trennlamelle vor dem Düsenspalt des Stoffauflaufes erfolgt.To achieve this object, the two retaining strips are fastened to the separating element on the device according to the invention, a pressure chamber of a pressure device which can be acted upon by a pressure medium being provided between the retaining strips, as a result of which the retaining strips can be expanded relative to one another. By applying a pressure in the pressure chamber Pressure device gap the holding strips apart and leave a space between them that is necessary for attaching or detaching the separating lamella between the holding strips. After the pressure in the pressure chamber has been reduced, the retaining strips come into contact with one another, as a result of which the separating lamella used is held in place in front of the nozzle gap of the headbox.

Die Vorrichtung 1 zum Halten einer Trennlamelle 2 gehört zu einem Mehrschicht-Stoffauflauf einer Papiermaschine, die z.B. zur Herstellung von Mehrschicht-Tissue-Papieren vorgesehen ist. Hier ist ein Zweischicht-Stoffauflauf schematisch vereinfacht dargestellt.The device 1 for holding a separating lamella 2 belongs to a multi-layer headbox of a paper machine which e.g. is intended for the production of multilayer tissue papers. Here a two-layer headbox is shown schematically simplified.

Die Trennlamelle 2 ist an einem Trennelement 4 befestigt, das einen Düsenraum 3 des Stoffauflaufes auf bekannte Weise teilt und nach außen durch einen Düsenspalt 5 zwischen einer oberen Lippe 31 und einer unteren Lippe 32 ragt. Die Trennlamelle 2 kann zum weiteren Getrennthalten der in diesem Falle zwei Stoffschichten nach Verlassen des geteilten Düsenraumes 3 über eine Strecke in Laufrichtung der Papiermaschine dienen.The separating lamella 2 is fastened to a separating element 4 which divides a nozzle chamber 3 of the headbox in a known manner and projects outwards through a nozzle gap 5 between an upper lip 31 and a lower lip 32. The separating lamella 2 can serve to further separate the two layers of material in this case after leaving the divided nozzle space 3 over a distance in the running direction of the paper machine.

Eine solche Ausführungsform ist hier gezeigt, wobei die die Trennlamelle 2 jeweils verkürzt in der Maschinenrichtung dargestellt ist. Die tatsächliche Länge der Strecke, bzw. der Trennlamelle 2 wird den jeweiligen Betriebsbedingungen der Papiermaschine, bzw. Eigenschaften der Stoffschichten angepaßt.Such an embodiment is shown here, the separating lamella 2 being shown shortened in the machine direction. The actual length of the line or the separating lamella 2 is adapted to the respective operating conditions of the paper machine or properties of the layers of material.

Die Vorrichtung 1 weist eine obere Halteleiste 6 und eine untere Halteleiste 7 auf, die an dem Trennelement 4 über eine Verbindungsstelle 14 ohne Höhenunterschied zwischen der stoffseitigen Oberflächen des Trennelements 4 und der Halteleisten 6 und 7 befestigt sind. Dazu ist eine Schwalbenschwanzverbindung an der Verbindungsstelle 14 vorgesehen. Die Befestigung weist wechselseitig angeordnete Schrauben 15 auf, die die Halteleisten zusammenfügen und zusammendrücken und ihnen dabei Vorspannung erteilen. Anstelle der Schrauben 15 können auch Niete verwendet werden.The device 1 has an upper holding strip 6 and a lower holding strip 7, which are fastened to the separating element 4 via a connection point 14 without a height difference between the fabric-side surfaces of the separating element 4 and the holding strips 6 and 7. For this purpose, a dovetail connection is provided at the connection point 14. The attachment has mutually arranged screws 15 which join and press the retaining strips together and thereby give them pretension. Instead of the screws 15, rivets can also be used.

Die Halteleisten 6 und 7 verlaufen durchgehend über die gesamte Breite des Trennelementes 4 und sind zum Festhalten der Trennlamelle 2 zwischen sich ausgebildet. Dazu sind auch Nuten 21 vorgesehen, die an den der Trennlamelle zugewandten Flächen der Halteleisten 6 und 7 ausgeführt sind. So wird ein tunnelartiger Raum gebildet, in dem ein Befestigungsrand 22 der Trennlamelle 2 einschließbar ist.The holding strips 6 and 7 run continuously over the entire width of the separating element 4 and are designed to hold the separating lamella 2 between them. For this purpose, grooves 21 are also provided, which are designed on the surfaces of the holding strips 6 and 7 facing the separating lamella. A tunnel-like space is thus formed, in which a fastening edge 22 of the separating lamella 2 can be enclosed.

Zwischen den der Trennlamelle 2 zugewandten Flächen der Halteleisten 6 und 7 ist eine mit einem Druckmittel beaufschlagbare Druckkammer 8 einer Druckvorrichtung vorgesehen, die zum Spreizen der Halteleisten 6 und 7 relativ zueinander dient. Beim Aufbringen eines Druckes in die Druckkammer 8 werden die Halteleisten 6 und 7 so weit gespreizt, daß die Trennlamelle 2 entfernt, bzw. eingesetzt werden kann. Dies ist besonders in Fig. 2 dargestellt.Provided between the surfaces of the holding strips 6 and 7 facing the separating lamella 2 is a pressure chamber 8 of a pressure device which can be acted upon by a pressure medium and which serves to spread the holding strips 6 and 7 relative to one another. When applying a pressure in the pressure chamber 8, the holding strips 6 and 7 are spread so far that the separating lamella 2 can be removed or used. This is particularly shown in Fig. 2.

Die Druckkammer 8 hat die Form einer zwischen den Halteleisten 6 und 7 bzw. in ihnen durchgehenden Nut, die mit einer dichtenden Auskleidung 9 ausgekleidet ist. Diese Auskleidung 9 ist aus einer elastischen, undurchlässigen Folie hergestellt.The pressure chamber 8 has the shape of a groove between the holding strips 6 and 7 or in them, which is lined with a sealing lining 9. These Lining 9 is made of an elastic, impervious film.

Der von der Auskleidung 9 umhüllte Raum der Druckkammer 8 ist über Leitungen 10 und 11 für das beaufschlagende Druckmittel, die als Bohrungen zwischen den Halteleisten 6 und 7 bzw. in dem Trennelement 4 ausgeführt sind, einer nicht gezeichneten Druckmittelquelle angeschlossen. Die bezüglichen Anschlüsse befinden sich vorteilhafterweise an beiden Seiten des Trennelements 4. Damit ist es auch möglich, das System von einer Seite, wenn notwendig, durchzuspülen.The space of the pressure chamber 8 enveloped by the lining 9 is connected to a pressure medium source, not shown, via lines 10 and 11 for the pressurizing medium which are designed as bores between the holding strips 6 and 7 or in the separating element 4. The relevant connections are advantageously located on both sides of the separating element 4. It is also possible to flush the system from one side if necessary.

Wie oben erwähnt, werden die Halteleisten 6 und 7 zur Vorspannung mittels der Schrauben 15 zusammengedrückt. Bei dem Voneinanderdrücken der Halteleisten 6 und 7 kommt es zu einer elastischen Deformation der Halteleisten im Bereich der Schrauben 15.As mentioned above, the holding strips 6 and 7 are pressed together by means of the screws 15 for pretensioning. When the retaining strips 6 and 7 are pressed together, the retaining strips in the region of the screws 15 undergo elastic deformation.

Die Halteleisten 6 und 7 sind zueinander spiegelbildlich ausgeführt. Nach einer Ausführungsform, die in den Fig. 1 und 2 dargestellt ist, enden die Halteleisten 6 und 7 in der Auslaufrichtung des Stoffes mit einer Spitze, so daß an der Stelle, wo die Enden der Halteleisten 6 und 7 zum Anliegen an die Trennlamelle 2 kommen, keine Wirbel in dem Stoffstrom entstehen.The holding strips 6 and 7 are mirror images of one another. According to one embodiment, which is shown in FIGS. 1 and 2, the holding strips 6 and 7 end with a tip in the outlet direction of the fabric, so that at the point where the ends of the holding strips 6 and 7 lie against the separating lamella 2 come, there are no vortices in the material flow.

Nach einer anderen Ausführungsform, die besonders in der Fig. 5 gezeigt ist, enden die Halteleisten 6 und 7 stumpf mit einer quer zur Auslaufrichtung stehenden Kante 13, so daß an der Stelle, wo die Enden der Halteleisten 6 und 7 zum Anliegen auf die Trennlamelle 2 kommen, eine Wirbel bildende Stufe ausgebildet ist. Dies kann bei gewissen Betriebssituationen gewünscht sein.According to another embodiment, which is shown particularly in FIG. 5, the holding strips 6 and 7 end bluntly with an edge 13 which is transverse to the outlet direction, so that at the point where the ends of the holding strips 6 and 7 lie against the separating lamella 2 come, a vortex forming stage is formed. This may be desirable in certain operating situations.

Es ist aber auch möglich, wenn bei dieser Ausführungsform gemäß Fig. 5 wahlweise eine Wirbelbildung an den Enden 13 der Halteleisten 6 und 7 zu vermeiden ist, eine Trennlamelle einzusetzen, die in der Fig. 4 dargestellt ist. Diese Trennlamelle 2 ist an dem den Halteleisten 6 und 7 zugewandten Ende mit einem, im vertikalen Längsschnitt gesehen, keilförmigen Passungsteil 23 versehen. Dieser Passungsteil 23 ist an seiner höchsten Stelle genau so hoch wie die Kante 13 aufweisenden Enden der Halteleisten 6 und 7. Beim Einklemmen dieser Trennlamelle entsteht also keine wirbelbildende Stufe zwischen dem Passungsteil 23 und den Halteleisten 6 und 7.It is also possible, however, if, in this embodiment according to FIG. 5, optionally formation of eddies at the ends 13 of the holding strips 6 and 7 is to be avoided, to use a separating lamella, which is shown in FIG. 4. This separating lamella 2 is on the end facing the holding strips 6 and 7 is provided with a wedge-shaped fitting part 23, seen in the vertical longitudinal section. At its highest point, this fitting part 23 is exactly as high as the ends of the holding strips 6 and 7 that have the edge 13. When this separating lamella is clamped in, there is therefore no swirl-forming step between the fitting part 23 and the holding strips 6 and 7.

Der Schutzumfang betrifft auch die Anwendungsfälle, in denen ein Mehrschicht-Stoffauflauf für mehr als zwei Stoffschichten ausgelegt ist, sowie auch die, in denen der Stoffauflauf im Raume nicht horizontal, sondern vertikal oder schräg nach unten weist.The scope of protection also applies to applications in which a multi-layer headbox is designed for more than two layers of material, as well as those in which the headbox in the room does not point horizontally, but vertically or at an angle.
