Definitions

  • the invention relates to a calender with a frame and a stack of superimposed, at least partially covered rollers, of which at least one intermediate roller arranged between other rollers is held in roller bearings attached to pivoting levers, means for reducing the transverse displacement of the central roller axis being provided are and the pivoting levers are pivotable in bearing blocks, which are each arranged on a vertical, frame-fixed track.
  • swivel levers In the case of calenders, it is often desirable to support the center rollers via swivel levers because the roller bearings can be adjusted with much less friction when the rollers are turned on and off than if they were guided directly on a stand of the frame.
  • the swivel lever In the majority of all cases, the swivel lever is fixedly mounted on the stand (US-A-2 850 952).
  • Such a pivot lever can also be loaded by a compensator which can be pressurized with pressure such that the effect of the overhanging weights formed by the roller bearings and other parts on the deflection of the center roller is reduced or eliminated.
  • bearing housings which are fastened to a stand column by means of fastening screws on a track formed by vertically running grooves, have pins with adjustable eccentrics on which the pivot levers are pivotably mounted. With the help of these adjustable eccentrics, the roller can be adjusted essentially horizontally.
  • adjustable eccentrics only allow a limited compensation of the transverse displacement occurring during a swiveling movement; it is not sufficient for large differences in diameter of the exchangeable center roll.
  • the means for reducing the transverse displacement of the center roll axis consist of a short guide lever which is articulated on the one hand in the middle of the pivot lever length and on the other hand stationary on the frame. Because of this guidance, the pivot lever can no longer be firmly connected to its pivot pin fixed to the frame; rather, a sliding guide is provided between the pivot lever and pivot pin, which enables a relative movement in the direction of the pivot lever.
  • a sliding guide is provided between the pivot lever and pivot pin, which enables a relative movement in the direction of the pivot lever.
  • the invention has for its object to provide a calender of the generic type, which has a simple structure while maintaining the operational properties and is able to keep the transverse displacement of the center roll axis small with the required pivoting movements even with large differences in diameter of the center rolls to be replaced.
  • the height-adjustable bearing blocks are held by a motor-driven hanging device. Under the influence of the roller weight, there is a tensile load on the hanging device and thus a stable position of the bearing blocks on the vertical path. In this way, the quite considerable forces can be better transferred to the frame than if the bearing blocks are clamped onto the frame or supported from below.
  • a stop for limiting the pivoting movement of the pivoting lever is carried by a support arm which is height-adjustable together with the pivoting lever. Since the height of the support arm and swivel lever are adjusted together, the assignment once selected is retained even with this adjustment.
  • the support arm can be firmly attached to the bearing block.
  • the connecting line between the switching valve and the first pressure chamber can have two parallel sections, one of which is blocked by the piston when it has covered part of its way from the working position to the rest position, and the other of which is provided with a throttle.
  • Each center roller therefore first performs a fast separating movement when it is switched off, because the pressure medium can flow out over both parallel sections. However, braking is carried out before the stop determining the rest position is reached.
  • the pressure chamber 160 located under the piston 157 is connected via a line 161 to an electromagnetically actuated switching valve 162.
  • the first pressure chamber 160 is connected to the container 132.
  • a pressure reducing valve serves as the pressure fluid source 163 of selectable pressure, which is supplied by a pump 131.
  • This pump is - via corresponding switching valves 162a and pressure reducing valves 163a - also responsible for the pressure in the first pressure chamber 160a of the compensator 143a and possibly other compensators.
