Abstract

The roller body consists of annular discs (3 or 5) lined up on an axle (1) and consisting of porous material. The material of the roller body is compressed by uniform axial compression applied from the end faces. Since, before the compression, a larger volume of material is provided in the region near the axle than in the region distant from the axle, during compression there is a higher material density in the region near the axle than in the region distant from the axle. A squeezing roller constructed in this way has not only good wiping-off and squeezing properties with regard to the fluid, but also a long service life. <IMAGE>

Description

Die Erfindung betrifft eine Abstreif- oder Quetschwalze der im Oberbegriff des Anspruchs 1 genannten Art.The invention relates to a stripper or squeeze roller of the type mentioned in the preamble of claim 1.

Solche Abstreif- oder Quetschwalzen werden bei der Herstellung und Weiterverarbeitung verschiedenster Materialien verwendet. So werden diese Walzen bei der Papier- oder Textilherstellung benutzt, um aus feuch- ten Textil- oder Papierbahnen die Feuchtigkeit zu entfernen. Die Qualität einer solchen Walze richtet sich aber nicht nur nach dem Abstreif- oder Quetscheffekt, sondern auch nach der Standzeit.Such stripping or squeezing rollers are used in the manufacture and processing of a wide variety of materials. Thus, these rolls are used in paper or textile manufacture in order from damp t en textile or paper webs, the moisture to be removed. The quality of such a roller depends not only on the scraping or squeezing effect, but also on the service life.

Eine bekannte Abstreif- oder Quetschwalze, die bei der Papier- und Textilherstellung Verwendung findet, besteht aus mehreren, auf einer Achse aufgereihten Ringscheiben aus Faservlies. Die Ringscheiben stehen durch axiale Druckbeaufschlagung unter Vorspannung und sind wärmebehandelt (DE-PS 872 490, DE-PS 361 437, DE-GM 1 965 495 und Textilpraxis, Oktober 1959, S. 1037).A known scraper or squeeze roller, which is used in paper and textile production, consists of several ring disks made of nonwoven fabric lined up on an axis. The annular disks are pretensioned by axial pressure and are heat-treated (DE-PS 872 490, DE-PS 361 437, DE-GM 1 965 495 and Textilpraxis, October 1959, p. 1037).

Der Erfindung liegt die Aufgabe zugrunde, eine Abstreif-oder Quetschwalze zum Entfernen von auf bzw. in Körpern, insbesondere Warenbahnen befindlicher Flüssigkeit zu schaffen, die bei gutem Abstreif- und Quetscheffekt eine lange Standzeit hat.The invention has for its object to provide a wiping or squeezing roller for removing liquid on or in bodies, in particular webs, which has a long service life with good wiping and squeezing effect.

Diese Aufgabe wird durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst.This object is achieved by the characterizing features of claim 1.

Aufgrund der von außen nach innen zunehmenden Härte des Walzenkörpers wird nicht nur ein sehr guter Abstreif-und Quetscheffekt, sondern auch eine sehr lange Standzeit bei verhältnismäßig einfachem Aufbau des Walzenkörpers erreicht.Due to the increasing hardness of the roller body from the outside in, not only is a very good wiping and squeezing effect achieved, but also a very long service life with a relatively simple structure of the roller body.

Eine größere Härte und damit auch eine geringere Porösität des Walzenkörpers im achsnahen-Bereich kann auf verschiedene Weise erhalten werden. So können gleichartige Scheiben verwendet werden, die im achsnahen Bereich dicker als im achsfernen Bereich sind. Es ist aber auch möglich, verschiedenartige Scheiben zu verwenden, und zwar solche mit großem Außendurchmesser und solche mit kleinem Außendurchmesser. Die Scheiben kleinen Außendurchmessers können aus dem gleichen Material wie die Scheiben großen Außendurchmesser sein, sie können aber auch aus weniger kompressiblem Material bestehen. Im letzteren Fall wird mit einer geringeren Anzahl kleiner Scheiben eine bestimmte Kompression erreicht. Die Scheiben geringerer Kompressibilität können aus steifem Material, insbesondere Stahl, bestehen. In einem solchen Fall geben sie dem Walzenkörper zusätzlich Stabilität.A greater hardness and thus also a lower porosity of the roller body in the area near the axis can be obtained in various ways. It is thus possible to use disks of the same type which are thicker in the area near the axis than in the area away from the axis. However, it is also possible to use different types of disks, namely those with a large outside diameter and those with a small outside diameter. The disks of small outer diameter can be made of the same material as that Discs are large outside diameter, but they can also consist of less compressible material. In the latter case, a certain compression is achieved with a smaller number of small disks. The lower compressibility discs can be made of stiff material, especially steel. In such a case, they give the roller body additional stability.

Im folgenden wird die Erfindung anhand einer zwei Ausführungsbeispiele darstellenden Zeichnung näher erläutert. Im einzelnen zeigen

  • Fig. 1 eine Abstreif- und Quetschwalze im Axialschnitt,
  • Fig. 2 einen Ausschnitt aus der Walze gemäß Fig. 1 vor der axialen Kompression der Ringscheiben und
  • Fig. 3 einen Teil einer Abstreif- oder Quetschwalze im Axialschnitt mit zu den Ringscheiben gemäß Fig. 1 und 2 andersartigen Ringscheiben.
The invention is explained in more detail below with the aid of a drawing showing two exemplary embodiments. Show in detail
  • F ig. 1 a stripping and squeezing roller in axial section,
  • Fig. 2 shows a section of the roller of FIG. 1 before the axial compression of the washers and
  • Fig. 3 shows a part of a stripping or squeezing roller in axial section with the washers according to FIGS. 1 and 2 different types of washers.

Die in der Zeichnung dargestellten Abstreif- und Quetschwalzen bestehen aus einer hohlen Achse 1, 2 und darauf aufgereihten Ringscheiben 3, 4 aus Vliesstoff. Als Fasern für den Vliesstoff eignen sich Natur- oder Kunststoffasern, z.B. Baumwollfasern, Polyamidfasern oder Polyesterfasern. Die Fasern sind durch einen elastischen Binder miteinander verbunden.The stripping and squeezing rollers shown in the drawing consist of a hollow shaft 1, 2 and ring disks 3, 4 made of nonwoven fabric lined up thereon. Natural or plastic fibers are suitable as fibers for the nonwoven, e.g. Cotton fibers, polyamide fibers or polyester fibers. The fibers are connected to each other by an elastic binder.

Beim Ausführungsbeispiel der Fig. 1 und 2 haben die Ringscheiben 3 im achsnahen und achsfernen Bereich die gleiche Dicke. Zwischen den Ringscheiben 3 sind verteilt Ringscheiben 5 mit kleinerem Außendurchmesser angeordnet. Die Ringscheiben 5 können aus dem gleichen Material wie die Ringscheiben 3, aber auch aus einem weniger porösen, ja sogar steifen, Material, wie Stahlblech bestehen. Aufgrund dieser Ringscheiben kleineren Außendurchmessers ergibt sich eine unterschiedliche Volumenverteilung im Bereich des Walzenkörpers in radialer Richtung.In the embodiment of FIGS. 1 and 2, the ring disks 3 have the same thickness in the area near the axis and away from the axis. Between the ring disks 3, ring disks 5 with a smaller outside diameter are distributed. The washers 5 can be made of the same material as the washers 3, but also of a less porous, even stiff, material, such as sheet steel. Due to these ring disks with a smaller outside diameter, there is a different volume distribution in the area of the roller body in the radial direction.

Beim Ausführungsbeispiel der Fig. 3 wird diese unterschiedliche Volumenverteilung durch eine im Querschnitt konische Form der Ringscheiben 4 erreicht.In the embodiment of FIG. 3, this different volume distribution is achieved by a conical shape of the ring disks 4 in cross section.

Nach Aufreihung der Ringscheiben 3, 4, 5 auf die hohlen Achsen 1, 2 entsprechend den Darstellungen der Fig. 2 und 3 werden auf beiden Stirnseiten steife . Ringscheiben 6, 7 aufgebracht und der gesamte Aufbau der Ringscheiben 3 bis 7 in axialer Richtung zusammengedrückt.After the ring disks 3, 4, 5 have been lined up on the hollow axes 1, 2, as shown in FIGS. 2 and 3, they become rigid on both end faces. Washers 6, 7 applied and the entire structure of the washers 3 to 7 compressed in the axial direction.

Dabei wird wegen des größeren Materialvolumens im achsnahen Bereich das Material des Walzenkörpers im achsnahen Bereich stärker komprimiert als im achsfernen Bereich. Dann werden die Ringscheiben 6, 7 auf der hohlen Achse 1, 2 durch in Nuten eingreifende Sprengringe 8, 9 fixiert.Because of the larger volume of material in the area near the axis, the material of the roller body in the area near the axis is compressed more than in the area away from the axis. Then the washers 6, 7 are fixed on the hollow axis 1, 2 by means of snap rings 8, 9 engaging in grooves.

Als Material für die Ringscheiben 3, 4 eignet sich neben Faservlies Filz und Flanell. Gute ergebnisse wurden mit einer Walze erzielt, bei der eine Härtedifferenz von 10 bis 15 Shore A zwischen äußeren und inneren Bereichen des Walzenkörpers, insbesondere bei absoluten Werten von 80 und 95 Shore und bei einer Breite von jeweils 25 mm für die beiden Bereiche bestand.In addition to fiber fleece, felt and flannel are suitable as materials for the ring disks 3, 4. Good results have been achieved with a roller with a difference in hardness of 10 to 15 Shore A existed between the outer and inner areas of the roller body, in particular with absolute values of 80 and 95 Shore and with a width of 25 mm for the two areas.
