Definitions

  • the invention relates to a method for measuring and controlling the Nip réelles in the press of a paper machine, especially in one Shoe press, across and / or along the web running direction. Furthermore concerns the invention an apparatus for performing the method.
  • the aim of the invention is thus a method and device for measurement and regulation of the nip pressure in the transverse and / or longitudinal direction a press to achieve a uniform moisture profile or Setting paper quality parameters to create.
  • the invention is therefore characterized in that the hydraulic static pressure at reference points via measuring holes in the press nip is measured.
  • the Pressure setpoint for regulating the nip pressure in the transverse direction or Determine the actual pressure curve in the longitudinal direction very well.
  • An advantageous development of the invention is characterized in that that the nip pressure of the press in the transverse direction to this setpoint regulated and thus continuously adapted. With such a Regulation can be done in any production state across the machine direction achieve an even press work.
  • a favorable embodiment of the invention is characterized in that that the setpoint of the pressure is set differently across the web width becomes. This can specifically influence the moisture profile of the paper web become.
  • the invention also relates to a device for measurement and control the nip pressure in the press of a paper machine, especially in a Shoe press, across and / or along the web running direction. It is through it characterized that across the press and / or Measuring holes are provided along the web running direction, which in the Press nip is sufficient. By measuring the pressure The entire pressure curve can be exactly determined using reference points regulate accordingly.
  • the nip pressure profile can also be particularly good the moisture profile can be controlled across the web direction.
  • the press shoe position in Longitudinal direction are shifted and thus the nip pressure longitudinal profile in Nip can be set or regulated.
  • FIG. 1 shows a schematic pressure curve in a press
  • FIG. 2 a cross section through a press roller
  • Fig. 3 is a plan view and Cross section on the press shoe of a shoe press according to the invention shows.
  • Fig. 1 shows a course of the pressure of a shoe press in Web direction x.
  • curves 1a, 1b, 1c for different products.
  • Positions 2, 2a, 2b, 2c for pressure measuring points in the web running direction are shown. By knowing the pressure values at these points, the Determine influence on paper quality and correct or regulate.
  • This counter roll 5 can optionally also be the drying cylinder a tissue machine.
  • the roller consists of an outer press jacket 6 and a support ring 7 on which the pressure shoe 8 is supported.
  • the pressure shoe 8 is attached to the press jacket 6 by means of pressing elements 9 pressed.
  • a return spring 10 is provided here for pressure relief.
  • the shoe end stop 15 is adjustable in the direction of web travel.
  • measuring bores 13, 13 ', 13 "and 14, 14', 14", 14 "'shown Measuring bores 14, 14 ', 14 ", 14"' are transverse to the web running direction arranged, while the measuring bores 13, 13 'and 13 "with a Bore 14 are arranged in the direction of web travel. These measuring holes correspond to the measuring points 2, 2a, 2b, 2c in FIG. 1.
  • Fig. 4 shows a section along line A-B in Fig. 2. It is here Shoe press roll 4 and the counter roll 5 shown. Over the web width are several pressure elements for pressing the pressure shoe intended. These can be done independently of one another via the oil supply line be operated. The relief is provided by return springs 10.
  • Fig. 5 shows a control scheme for a system according to the invention.
  • the oil pressure in the nip resulting from the admission pressure control becomes measured redundantly directly in the nip of the main zone, the measured values one Averaged and after evaluation with a correction factor used as a theoretical setpoint for the border zone control.
  • the position of the pressure measurements for the main zone is also variable.
  • Each edge zone has its own PID controller, wherein the actuator in the oil supply line to the pressure element of the respective Edge zone in front of the roller and the pressure measurement directly in the nip in the Position of the respective edge zone takes place.
  • this control concept gives the possibility of To keep pressure directly in the nip across the entire width and thus to achieve a really even line load.
