Definitions

  • the invention relates to a press device for a paper machine or the like, comprising a shoe press roll a stationary support body on which a press shoe radially is slidably mounted, the hydraulically to a counter roller is pressed, and with return means for withdrawing the Press shoe from the counter roll.
  • the known pressing device is a Long nip press device with a shoe press roll, which is hydraulic can be pressed against a counter roller.
  • the shoe press roll has a press shoe on a in the longitudinal direction of the press shoe running pressure chamber hydraulically to the counter roller can be pressed.
  • the pressure chamber is from the press shoe and a shoe bed formed on a stationary support body the shoe press roll supports. Runs over the press shoe in a known manner, a press jacket, which is used to minimize the Friction on the press shoe is hydrodynamically lubricated.
  • This construction is intended to achieve a design that is as flat as possible be to the dimensions of the shoe press unit, especially the Increase the size of the shoe bed in the radial direction to have to.
  • a similar pressing device is from DE 41 13 623 C1 known in the spring elements also within the pressure chamber are arranged, the prevailing in the pressure chamber Counteract pressure to enter with an almost unpressurized pressure chamber Pull the press shoe back towards the shoe bed to reach.
  • a disadvantage of such an assembly is that appropriate bushings are required, that require additional seals and that in addition holes are required in the support body, what with a corresponding Weakening of the supporting body is connected.
  • the press shoe is therefore provided not to press through a single elongated pressure chamber, but instead a plurality of in the longitudinal direction of the Press shoe's hydraulic cylinder / piston units lined up to use so that the contact pressure of the press shoe adapted to the necessary conditions over its longitudinal direction can be.
  • Spring elements are located within the cylinder / piston units provided to press the respective cylinder / piston unit to the press shoe even when the pressure chamber is depressurized ensure that even with insufficient pressure in the pressure chamber a clean contact of the sealing surfaces of the Cylinder / piston unit on the press shoe is guaranteed so that lateral leakage of hydraulic oil is avoided.
  • the Cylinder / piston units can be tilted by a certain amount arranged to allow application to the press shoe.
  • the known press device thus allows a sensitive Regulation of the pressure along the length of the press shoe, however, no measures have been taken to retracting the press shoe against the action of Ensure spring force in the direction of the supporting body.
  • no measures have been taken to retracting the press shoe against the action of Ensure spring force in the direction of the supporting body.
  • the maximum stroke of the piston / cylinder units is limited. Especially when the shoe press roll is arranged at the top, however, this is often not sufficient, especially for Starting up the paper machine and during maintenance and adjustment work.
  • a pressing device of a similar type is known from EP 0 345 501 B1 known, but with the same disadvantages as the previous one has described pressing device.
  • the invention is therefore based on the object of a pressing device to improve in accordance with the type mentioned at the beginning, that allows easy assembly and disassembly of the press shoe is and that the lowest possible weakening of the support body caused by the return means.
  • the object is achieved in that at a Press device of the type mentioned in the longitudinal direction of the press shoe a plurality of hydraulic elements for pressing the press shoe is provided on the counter roller, and that the Return means outside the hydraulic elements on the support body and attack the press shoe.
  • the contact pressure of the press shoe to the counter roll in the direction of the longitudinal extent of the press shoe to the necessary conditions can be adjusted if, for example, a reduction in Press pressure especially in the edge areas with narrower Paper webs than is normally required.
  • the return means spring elements that are substantially vertical arranged parallel to the hydraulic elements to the press shoe are.
  • the return means also as Hydraulic elements or other structures could be the use of spring elements is particularly preferred since as a result, the structure of the return means is particularly simple designed.
  • the spring elements in the axial direction of the spring elements extend extending tie rods, the press shoe facing ends via hinge connections with the press shoe are connectable.
  • clamping elements for tensioning the spring elements during assembly or at a Replacement of the press shoe provided.
  • the Clamping elements off-center on the mounts of the coil springs on.
  • lateral guide rails for receiving in the direction of web travel provided transverse forces acting on the press shoe.
  • the guide rails supporting the press shoe consist of individual guide pieces in the longitudinal direction of the press shoe are spaced from each other.
  • At least one hydraulic element one with hydraulic pressure pressurizable pressure chamber between the support body and the press shoe is formed in a cylindrical recess, and which is laterally delimited by a first sleeve which in the cylindrical recess is axially displaceable and tiltable is led.
  • the first sleeve can be directly in the cylindrical bore be led. In an alternative version, however, you can use a second sleeve interact telescopically.
  • the first sleeve versus a second in the cylindrical Recess on the support body by means of a sleeve Seal guided axially movable and tiltable.
  • first Sleeve arranged within the second sleeve and the pressure means is designed as a compression spring within the first Sleeve preferably between an end face of the cylindrical Recess and a projection of the first sleeve is arranged.
  • the second sleeve is within the first Sleeve arranged, and the pressure means designed as a compression spring is preferably between an outer projection second sleeve and an end face of the cylindrical recess arranged.
  • a sleeve is generally sufficient which together with the press shoe within the cylindrical Recess is movable.
  • the first sleeve - As already mentioned - also telescopic with a second sleeve interact that either inside or outside the first sleeve is arranged.
  • this can preferably designed as a spiral spring pressure element either inside the pressure room or outside the pressure room in the Recess be arranged.
  • the recess is preferably a cylindrical recess educated. However, instead of several consecutively arranged cylindrical recesses also within the support body a groove extending in the direction of the press shoe is provided be in which several hydraulic elements are accommodated.
  • a pressing device is shown in Fig. 1 and designated overall by the number 10.
  • the press device comprises a shoe press roll 12 with a hydraulic to a Counter roll 14 pressable press shoe 26, via which a tubular Press jacket 18 rotates, being in the area between the Press shoe 26 and the counter roll 14 formed a press nip 16 is.
  • the shoe press roll 12 has a stationary support body 24 with a series of circumferentially arranged guide strips 19 on which the tubular press jacket 18th can be guided outside the press nip 16. Usually runs he is contactless at a short distance from the guide rails 19th

  • Fig. 1 shows an arrangement in which the shoe press roll 12th is arranged above the counter roller 14. It goes without saying that the invention of course also in the reverse arrangement is advantageously used, in which the shoe press roll below is arranged.
  • FIG. 1 is a first inner sleeve 80 on the end face by means of a sealing ring 84 against the contact surface 93 of the press shoe 26 sealed.
  • An outer sleeve (or "Cylinder") 81 which surrounds the inner sleeve 80, is rigid connected to the support body 24 (e.g. by means of a not shown Screws). It is facing away from the press shoe 26 End face by means of an O-ring 92 against the end face 83 of the cylindrical recess 88 sealed and is at her the press shoe 26 facing end on the inside by a sealed radially against the inner sleeve 80 sealing ring 82.
  • the first sleeve 80 is by means of a pressure means 90, the arranged as a coil spring within the first sleeve 80 is pressed against the contact surface 93 of the press shoe 26, wherein the spring 90 rests on an annular web 86 of the sleeve 80.
  • first, inner sleeve 80 which is connected to the second, outer Sleeve cooperates, the end face 83 of the cylindrical Expansion 88 and the contact surface 93 of the press shoe 26 a pressure chamber bounded with the hydraulic channel Pressure can be applied. Since the first sleeve 80 to the contact surface 93 of the press shoe 26 is open and only opposite this is sealed, on the one hand there is mechanical wear avoided between the hydraulic element and the press shoe 26. On the other hand, horizontal relative movements between the Hydraulic element 30 and the press shoe tolerated, which e.g. by Thermal expansion or due to changes in load on the press shoe 26 could be. There is also a tilt in the guide of the sleeves 80, 81 avoided.
  • the pressure means 90 in the form of the spring achieves that in all operating conditions (even if in the hydraulic element 30 there is no hydraulic pressure), the inner sleeve 80 clean rests on the press shoe 26, so that a lateral escape of Hydraulic oil is avoided.
  • Fig. 1 there is none Hydraulic pressure available, so that the press shoe 26 under the Effect of return means 32, 34 (see below) on the support body 24 is present. If there is hydraulic pressure, then it rises the press shoe 26 from the support body 24; then he "swims" to a certain extent on that limited by the hydraulic element 30 Pressure pad and is only on the side via guide rails 74 guided, which the transverse forces occurring during operation record, tape.
