Definitions

  • the invention relates to a shoe roll according to the preamble of claim 1.
  • Devices with a shoe roll are known for treating a web, in particular for dewatering and / or calendering a paper or board web.
  • a press apparatus for a paper machine or the like which has a shoe roll and a counter roll.
  • the shoe roll comprises a stationary support on which a pressure shoe is mounted so as to be radially displaceable and can be hydraulically pressed against a counter roll.
  • the shoe roll has for this purpose a pressure shoe, which has a plurality of spaced-apart hydraulic elements for pressing the pressure shoe to the counter-roller in the longitudinal direction of the pressure shoe.
  • return means are provided which engage the support body outside the hydraulic elements.
  • the return means have spring elements which are arranged substantially perpendicular to the pressure shoe parallel to the hydraulic elements.
  • Out DE 41 13 623 C1 is an extended-nip press with a shoe roll and a counter-element in, for example, a papermaking machine, in which a connecting element between the pressure shoe and the carrier is provided.
  • a connecting element between the pressure shoe and the carrier is provided.
  • a limitation of the stroke of the pressure shoe is possible.
  • At the connecting element engages a spring whose spring force counteracts the pressure prevailing in the pressure chamber. So if the pressure chamber is depressurized, then the pressure shoe is pulled back under the spring force.
  • the spring is preferably formed as a compression spring. Alternatively, the spring can be replaced by a small hydraulic cylinder. The tensile forces are low.
  • the object of the invention is therefore to provide a shoe roll having return means that work reliably.
  • the return means is formed by a retraction device which engages the hydraulic cylinders.
  • the return means is thus subdivided into a plurality of individual retraction devices which are suitable for uniform and in the whole attractive drawback of the pressure shoe care. It is the merit of the inventor to have recognized that it is advantageous if the return means does not attack directly on the pressure shoe, but indirectly via the hydraulic element itself. The mechanical complexity is then low, and the return means works low maintenance. This applies in particular with regard to the lifting element used, which is individually controllable as a drive element.
  • the invention provided lifting element is fluidbeaufschlagbar or in the simplest form a compression spring.
  • fluidbeaufschlagbares lifting element preferably a fluidbeaufschlagbare annular chamber is provided.
  • Fig. 1 partially shows a shoe roll 1 for forming an extended nip with a backing roll 2 for the treatment of a material web, in particular a paper or board web.
  • the shoe roll 1 and the counter roll 2 preferably form a device for dewatering and / or calendering a paper or board web 3.
  • the shoe roll 1 is arranged overhead here. According to an embodiment, not shown, the shoe roll 1 may alternatively be arranged below or laterally at an angle to the vertical.
  • the shoe roll 1 comprises a support 4, around which a rotatable, flexible roll shell 5 runs.
  • the roll shell 5 is supported in the extended nip on a lubricated running surface 7 of a pressure shoe 6 arranged on the carrier 4.
  • the shoe roll 1 may be formed as an open or closed shoe roll 1.
  • the roll shell 5 is closed on the edge by means of, for example, end disks.
  • the shoe roll 1 further comprises a hydraulic loading device 8, which presses the pressure shoe 6 to the counter roll 2 and to a plurality of hydraulic cylinders 9 has.
  • the plurality of hydraulic cylinders 9 is arranged in the longitudinal direction along the pressure shoe 6 spaced from each other.
  • the hydraulic cylinders 9 each have a piston element 10, which is arranged within a cylinder element 11, which defines a working chamber 12.
  • the working chamber 12 can be acted upon by a hydraulic fluid with pressure.
  • the piston member 10 or the cylinder member 11 may be a two-piece member.
  • the cylinder element 11 is a two-piece element.
  • This two-piece cylinder element 11 comprises a first two-piece element 11.1, which is fixed relative to the pressure shoe 6, and a second two-piece element 11.2, which is spaced from the first two-piece element 11.1 and fixed relative to the support 4.
  • the second two-piece element 11.2 is formed by a recess of the carrier 4.
  • the piston member 10 here forms a coupler 15 which is in sealing engagement with the flange ends 13, 14 with the two-piece elements 11.1, 11.2.
  • the two-piece elements are thus in sealing engagement with the flange ends of a coupler as the respective other piston or cylinder element.
  • the coupler 15 is in engagement with a retraction device 16, which is a lifting element having a provided on the support 4 Displacement 17, which limits the carrier 4 held on the flange end 13 of the coupler 15 as a piston surface.
  • the coupler 15 also works as an actuatable driver for moving the pressure shoe 6 towards the carrier 4 when the retraction device 16 is activated, to which the pressure shoe 6 mounted flange 14 of the coupler 15 is connected as an engagement member with the pressure shoe 6.
  • a stop 18 is provided, against which the coupler 15 is movable.
  • the lifting element of the retraction device 16 is preferably a fluidbeaufschlagbares lifting element with which the coupler 15 is in sealing engagement.
  • the supply of the displacement 17 with fluid can be controlled via a supply line 19.
  • the displacement 17 is preferably a fluidbeaufschlagbare annular chamber surrounding the flange 13.
  • the displacement 17 is limited to the carrier 4 and optionally an annular disc 21, which form a Hubraumwandung.
  • the lifting element of the retraction device 16 may also be a prestressable compression spring which is effective in relieving the working chamber 12 of the hydraulic cylinder 9 and retracts the pressure shoe 6 via the coupler 15.
  • the coupler 15 is guided within the two-piece elements 11.1, 11.2.
  • the coupler 15 is disposed outside of the two-piece elements 11.1, 11.2.
  • the two-piece elements 11.1, 11.2 thus form according to Fig. 5 two Piston, and the coupler 15 forms the common cylinder of the hydraulic cylinder.
  • Fig. 2 shows a second embodiment of the shoe roll 1, in which on the carrier 4, the one two-piece element 11.2 in a modification of Fig. 1 no recess in the carrier 4, but is formed by a fastened to the carrier 4 essay 20. Otherwise, the comments on the first exemplary embodiment according to FIG Fig. 1 here accordingly.
  • Fig. 3 and Fig. 4 show the operation of the retraction device 16. Is starting from Fig. 2 Where the loading device 8 loads the pressure shoe 6 with a selectable pressure in the working chamber 12, relieves this pressure, the displacement 17 is subjected to fluid via the supply line 19. As a result, the coupler 15 is moved in the direction of the carrier 4, and the flange 14 moves against the stop 18, as in Fig. 3 is shown. The bearing on the pressure shoe 6 flange 14 of the coupler 15 is thus brought into engagement with the stop 18 which is provided on the fixed to the shoe two-piece element 11.1. After this engaged position engages the flange 14 of the coupler 15 with a tensile force on the two-piece element 11.1, which is fixed to the pressure shoe 6. As a result, the pressure shoe 6 is withdrawn. A maximum retraction travel can be adjusted by striking the flange end 13 on the carrier 4.
