Definitions

  • the invention relates at least to a roll shell for a rotatable press roll partially consisting of a plastic, its production and use of the roll shell in press rolls for measuring the pressure curve in one Press nip of a machine for producing and / or finishing a paper, cardboard, Tissue or other fibrous web.
  • the object of the invention is therefore to measure the pressure profile in the press nip with simple means.
  • the object with respect to the roll shell was achieved by that there is at least one pressure sensor in the plastic.
  • This pressure sensor detects the, on the roll shell when running through the press nip on the Plastic pressure.
  • This pressure is a measure of who, by whom Press nip guided material web exerted pressure and can thus contribute to the evaluation Problems are used.
  • This measuring device is simply constructed and with associated with high accuracy.
  • pressure sensors In order to be able to record the pressure curve axially along the press nip, should in the plastic several, preferably at least axially distributed over the roll shell arranged pressure sensors are located.
  • the pressure sensors can also be distributed radially over the roll shell, which extends the measuring range.
  • a pressure transmitter should be assigned to the pressure sensor, which is preferably arranged in or on the roller shell.
  • Each pressure sensor can have its own pressure sensor or several pressure sensors.
  • roller jacket should at least predominantly preferably entirely made of plastic and / or at least one outer layer, preferably the outer layer of the roll shell made of plastic.
  • the roller shell is predominantly or entirely made of plastic there is, this often has reinforcing elements, preferably in the form of Reinforcing threads. These reinforcing elements increase the mechanical Resilience and dimensional stability of the roll shell. With regard to the safe positioning of the pressure sensor, it is advantageous if the Pressure sensor is mechanically connected to at least one reinforcing element.
  • the process according to the invention for producing the roll shell is thereby characterized in that the pressure sensor in the roll shell or layer Plastic is poured.
  • This is relatively simple and also allows that during the manufacture of the roll shell with the pressure sensor Measured value transmitter and / or an electrical connection to the measured value transmitter is poured.
  • a receiver should receive the signals from the transmitter arranged outside the roll shell or even the press roll his.
  • the fibrous web 3 may also be used together at least one endless belt, for example in the form of a press felt by a press nip formed by the press roll and a counter roll 6 guided.
  • the counter roller 6 has a cylindrical shape, it has Press roll built in for measuring purposes, a flexible roll jacket 1 Roller shell 1 over a between the roller shell 1 and the axis of Pressing device 7 pressed to the counter roller 6 pressed.
  • the Support device 7 is formed by a hydraulically pressed support shoe, which to form an extended press nip with the counter roller 6 a has a concave contact surface.
  • a plurality of pressure sensors 2 arranged axially next to one another cast. These pressure sensors 2 are also in the roll shell 1 cast electrical connection 4 connected to a measured value transmitter 5, which arranged the measured value signals to an outside of the press roller Measured value receiver transmitted.
  • This measurement receiver is with a Data processing unit connected for evaluating the measurement results.
  • Figure 3 shows a press nip through which during the measurement of the pressure curve in the press nip neither a fibrous web 3 nor a band becomes.
  • the counter roll 6 and the press roll have a cylindrical shape, wherein the press forces over the axes of the press roll and the counter roll 6 be initiated.
  • the press roll has a roll jacket 1 Plastic, which is on a support device 7 in the form of the roller axis supported. Since there is no deformation of the roll shell 1 as in the above Examples are done, no reinforcing elements in the plastic are required.
  • Several compact measuring units are distributed axially and radially in the plastic each in the form of a pressure sensor 2, the electrical connection 4 and the Measured value transmitter 5 cast in.
