Description

Die Erfindung betrifft eine Walze für die Druckbehandlung von textilen Warenbahnen oder dergleichen, insbesondere für ein Quetschwerk zum gleichmäßigen Entwässern von textilen Stoffbahnen, mit einem drehbaren Walzenkern und einem dem Walzenkern umgebenden Mantelrohr, das an seinen Enden für Durchbiegungskorrekturen elastisch mit veränderbaren Abstützdrücken und außerdem in der Mitte auf dem Walzenkern drehfest abgestützt ist, wobei im Bereich der Enden des Mantelrohres Druckkissen zwischen einem im Mantelrohr drehbar gelagerten Außentragring und einem am Walzenkern drehbar gelagerten Innentragring angeordnet sind und wobei zu den Druckkissen Druckmittelleitungen führen.The invention relates to a roller for pressure treatment of textile webs or the like, in particular for a squeeze mechanism for even dewatering of textiles Fabric panels, with a rotatable roller core and a the casing tube surrounding the roll core, which at its Ends for deflection corrections elastic with changeable Outrigger and also in the middle on the Roll core is supported in a rotationally fixed manner, wherein in the area of Ends of the casing pipe pressure cushion between one in the casing pipe rotatably mounted outer support ring and one on the roller core rotatably mounted inner support ring are arranged and wherein pressure medium lines lead to the pressure pads.

Eine bekannte Walze dieser Gattung (DE 34 48 260 = Oberbegriff des Anspruches 1) kann praktisch nur als Schleppwalze eingesetzt werden, weil der Walzenkern an den außenseitig geschlossenen Innentragringen gelagert ist.A known roller of this type (DE 34 48 260 = preamble of claim 1) can can be used practically only as a drag roller because of Roll core on the inside closed inner rings is stored.

Der Einsatz einer Schleppwalze setzt unter anderem voraus, daß ein bestimmter Walzenandruck zu angetriebenen Gegenwalze unter Berücksichtung der Eigenschaften der zu behandelnden Warenbahnen eingestellt wird, damit die Walze mitlaufen kann.The use of a drag roller requires, among other things, that a certain roll pressure to driven counter roll taking into account the properties of the to be treated Material webs is set so that the roller runs with it can.

Aufgabe der Erfindung ist es, eine Walze der eingangs beschriebenen Gattung so zu verbessern, daß unabhängig von den Eigenschaften der zu behandelnden Warenbahn zusätzlich die Einstellung eines Walzenspaltes zur Gegenwalze möglich ist.The object of the invention is to provide a roller of the type described above To improve the genus so that regardless of the properties of the web to be treated in addition the setting of a nip to the counter roll possible is.

Diese Aufabe wird dadurch gelöst, daß die Außentragringe und die Innentragringe drehfest an Flanschringen gehalten sind, die eine Verdrehsicherung aufweisen, und daß sich die Enden des Mantelkerns durch die Flanschöffnungen der Flanschringe erstrecken sowie außerhalb der Flanschringe gelagert sind. Da die Enden des Mantelkerns frei zugänglich sind, können sie mit einem Antrieb verbunden werden. Zweckmäßigerweise handelt es sich dabei um einen zentralen Antrieb, mit dem auch die Gegenwalze angetrieben wird. Um Betriebsstörungen bei radialen Ausgleichsbewegungen der Walze zu vermeiden, kann der Antrieb über Kupplungen oder Gelenkwellen an die Enden des Walzenkerns angeschlossen werden. Da nunmehr beide Walzen eines Walzenpaares, das aus der beschriebenen biegeelastischen Ausgleichswalze und zum Beispiel aus einer Vollkernwalze besteht, angetrieben werden können, ist eine Spalteinstellung zwischen den beiden Walzen möglich. Damit können zum Beispiel auch Beschichtungen durchgeführt werden.This task is solved in that the outer support rings and the inner support rings held in rotation on flange rings are that have an anti-rotation device, and that the ends of the jacket core through the flange openings of the Extend flange rings as well as outside the flange rings are stored. Because the ends of the jacket core are freely accessible they can be connected to a drive. This is expediently one central drive with which the counter roller is also driven becomes. For operational disturbances with radial compensating movements To avoid the roller, the drive can over Couplings or cardan shafts to the ends of the roll core be connected. Since both rollers are now one Roller pair, which is described from the flexurally elastic Compensation roller and for example from a solid core roller exists, can be driven is one Gap setting between the two rollers possible. In order to For example, coatings can also be carried out.

Eine Walze mit einem antreibbaren Walzenkern ist bekannt (DE 11 31 176). Zwischen dem Walzenkern und dem Mantelrohr sind über die Länge der Walze eine Vielzahl von nachgiebig elastischen Schläuchen angeordnet, die auf dem mit dem Walzenkern verbundene Felgen aufgesetzt sind und das Mantelrohr tragen sowie das Mantelrohr durch Reibschluß mitnehmen, wenn der Walzenkern angetrieben wird.A roll with a drivable roll core is known (DE 11 31 176). Between the roller core and the casing tube are a variety of compliant over the length of the roller elastic hoses arranged on the with the Rims connected to the roller core and the casing tube wear and take the jacket tube with you by friction, when the roll core is driven.

Bei einer bevorzugten Ausführung der Erfindung sind die Flanschringe mit den zugeordneten Außentragringen auch in axialer Richtung fest verbunden. Dazu können zum Beispiel Schraubverbindungen eingesetzt werden. Demgegenüber sind die Innentragringe radial verschiebbar an ihren Flanschringen gehalten. Das ermöglicht eine kurze Bauweise der elastischen Endabstützung zwischen Mantelrohr und Mantelkern und damit eine schlankere Ausführung der gesamten Walze. Dadurch wird auch der Abquetscheffekt verbessert.In a preferred embodiment of the invention, the Flange rings with the associated outer support rings also in axial direction firmly connected. You can do this, for example Screw connections are used. Are against the inner support rings can be moved radially on their flange rings held. This enables a short construction of the elastic end support between the casing tube and casing core and thus a leaner version of the whole Roller. This also improves the squeezing effect.

Wird die Verdrehsicherung von zumindest einem von der Lagerbuchse radial vorstehenden Zapfen gebildet, dann können auch die Druckmittelleitungen durch Zapfen zum Druckkissen geführt werden. Eine andere Anordnung der Druckmittelleitungen ist ohne weiteres möglich, weil die Flanschringe und die Druckkissen nicht rotieren.Is the anti-rotation of at least one of the bearing bush formed radially protruding pin, then can also the pressure medium lines through pins to the pressure cushion be performed. Another arrangement of the pressure medium lines is easily possible because the Do not rotate flange rings and pressure pads.

Vorzugsweise sind mehrere, über den Umfang verteilte Druckkissen vorgesehen, die unabhängig voneinander mit Druckmittel beaufschlagbar sind, daß die Durchbiegungskorrektur richtungsorientiert einstellbar ist. Zusätzlich kann die Richtung der Durchbiegungskorrektur dann eingestellt werden, wenn die Flanschringe nach Lösen der Verdrehsicherung drehverstellbar sind.Preferably, several are distributed over the circumference Pressure cushions provided that are independent of each other Pressure medium can be applied that the deflection correction is directionally adjustable. In addition the direction of the deflection correction can then be set the flange rings after loosening the anti-rotation lock are adjustable.
