Definitions

  • the invention relates to a press roll with a roll shell which is attached to support disks, rotatably mounted on a stationary support and is axially displaceable on the support, the roll cover being able to be placed under tension by a tensioning device which acts on the support disks.
  • Such press rollers known in the prior art are used in connection with counter-rollers for dewatering a fibrous web, in particular a paper or cellulose web, by the fibrous web to be dewatered, optionally in parallel with a web of felt or the like suitable for taking out squeezed water, between the rotating drives Counter roll and the free running roller jacket is carried out.
  • a press shoe is arranged inside the roller shell, with the aid of which the roller shell is pressed against the counter roller.
  • the inner surface of the roll casing is subject to considerable wear, so that the roll casing can be displaced in the axial direction on the press shoe in order to distribute the load on the roll casing evenly over its entire length.
  • this adjustment is carried out, for example, with compression springs and spindles or with two hydraulic cylinders arranged inside the roll shell.
  • this is done by turning the spindle outside the press unit.
  • a relatively complex control program is required for hydraulic adjustment, since the hydraulic cylinders are double-acting and the control system must take the resulting different adjustment forces into account due to the different surface on the bottom and piston rod side.
  • the invention has for its object to make the adjustment of the roll shell of the press roll easier.
  • the pretensioning of the roller shell and the adjustment are brought about by a combination of at least one, preferably more, pressure springs and at least one, preferably more, pressure medium cylinders, by the pressure medium cylinders on the one hand place the compression springs under prestress and, on the other hand, at the same time also bring about the displacement of the roll shell.
  • the position of the roll shell can be very simple in this case, e.g. with the aid of a position measuring system assigned to the hydraulic cylinder, for example.
  • the roll shell, for. B. for a jacket change can be relaxed very easily by relaxing the pressure medium cylinder (s), since the roller jacket then automatically moves into a predetermined rest position by the compression spring (s).
  • FIG. 1 shows an axial section through a press roll according to the invention
  • FIG. 2 shows a section through the press roll from FIG. 1 along the line II / II
  • FIG. 3 shows a detail of the press roll from FIG. 1 in the region of a pressure medium cylinder on an enlarged scale
  • 4 shows a schematic illustration of the arrangement according to the invention corresponding to FIG. 1.
  • a press roll according to the invention is shown in longitudinal section, which has a roll shell 1, a stationary support 2 and a press shoe 3.
  • the press shoe 3 is fastened on the carrier 2.
  • the roll shell 1 is pressed against the press shoe by a counter roll, not shown.
  • the roller shell 1 is supported on the carrier 2 via support disks 4, the support disks 4 essentially consisting of an inner ring 5 and an outer ring 6, which can be rotated relative to one another via a roller bearing 7.
  • the inner rings 5 of the support disks 4 are slidably mounted on sliding sleeves 8, the sliding sleeves 8 themselves being fixed immovably on the carrier 2.
  • the roller shell 1 By synchronously moving the support disks 4 in the direction of the double arrow 9, the roller shell 1 can be displaced relative to the press shoe 3, so that the load resulting from the pressing of the press shoe 3 on the roller shell 1 can be distributed over the entire length of the roller shell 1 by the Roll jacket 1 is moved back and forth continuously or at periodic intervals along the double arrow 9.
  • a tensioning device consisting of compression springs 11 and pressure medium cylinders 12 is provided according to the invention.
  • the compression springs 11 and pressure medium cylinders 12 are fastened on the one hand to the carrier 2 and on the other hand to pressure rings 13, the pressure rings 13 being supported on the inner rings 5 of the support disks 4.
  • the compression springs 11 are biased to pressure during operation.
  • the pressure medium cylinders 12 can be single-acting pressure medium cylinders, which also apply a pressure force between the carrier 2 and the pressure ring 13 during operation.
  • control for adjusting the roll shell 1 can also be carried out very simply.
  • a displacement measuring system 14 to the pressure medium cylinder 12 so that the position of the pressure medium cylinder 12 and thus also the position of the roller shell 1 can be easily adjusted.
  • FIGS. 1 and 2 four compression springs 11 are arranged at an angular distance of 90 ° to one another in the exemplary embodiment shown. Furthermore, two hydraulic cylinders 12 are provided which lie opposite one another with respect to the axis 10. With regard to the compression springs 11, the hydraulic cylinders are arranged offset by 45 °. The hydraulic cylinders 12 and the compression springs 11 can of course also be arranged in alignment in the axial direction 10 if the spatial conditions allow this.
  • Prevent carrier 2 which could lead to buckling of the compression springs 11.
  • FIG. 4 shows a schematic illustration of the arrangement according to the invention, two compression springs 11 and two pressure medium cylinders 12 being provided in this exemplary embodiment. These are supported on the inside on the stationary support 2 and on the outside on the inner rings 5 of the support disks 4 of the roll shell 1. By adjusting the pressure medium cylinders 12, the roller jacket 1 is accordingly pushed back and forth in the direction of the double arrow 9 relative to the stationary carrier 2.

Abstract

L'invention concerne un rouleau presseur présentant une enveloppe (1) fixée à des disques supports (4) et montée de façon à pouvoir tourner sur un support stationnaire (2) et glisser en sens axial sur ce support (2). L'enveloppe (1) du rouleau est placée sous précontrainte par l'intermédiaire d'un dispositif de serrage (11, 12) appliqué contre les disques supports (4). Ce dispositif de serrage (11, 12) comporte des ressorts de pression (11) s'appuyant d'un côté contre un disque support (4) et de l'autre contre ledit support (2), ainsi que des vérins à fluide de pression (12) s'appuyant contre l'autre disque support (4) et contre ledit support. Selon la présente invention, la précontrainte de l'enveloppe (1) du rouleau et son ajustage sont réalisés par une combinaison de ressorts de pression (11) et de vérins à fluide de pression (12), lesquels vérins à fluide de pression (12) placent d'une part les ressorts de pression (11) sous précontrainte et entraînent d'autre part le déplacement simultané de l'enveloppe (1) du rouleau.
