Definitions

  • the invention relates to a device for the lateral guidance of a rolled strip transported on a roller conveyor, preferably a hot strip in front of a winding device, provided on both sides of the rolled strip parallel first and second side guides which are displaceable by independently adjustable adjusting means to each other or away from each other.
  • Hot strip reels are arranged at the end of hot strip mills and have the function to wind hot strip after rolling into coils.
  • the tape is wound up under tension in order to produce a sufficiently tightly wound and edged straight band and to avoid cracking of the collar after the finish winding.
  • the strip may periodically run sideways.
  • the amplitude can decay, remain constant during the entire winding or grow.
  • the periodic bleeding is observed.
  • the triggers for the beginning of the vibrations are mainly unplanations or so-called "sabers" on the tape head, occurring during the winding train loss or other disturbances in the course of the winding process.
  • the winding quality is deteriorated.
  • the tape is not wound straight edge, it comes to loose turns and in extreme cases to instability and to stop the winding process.
  • the rolled strip travels sinusoidally on the collar, in the driver and between the side guides. It can on the waistband amplitudes of 50 mm and more can be achieved. There are high forces in the side guides, which can lead to edge damage and buckling of the band edge.
  • From the DE 40 03 717 A1 is a side guide for transported on a roller conveyor rolled strip, preferably hot strip in front of a reel known.
  • a side guide for transported on a roller conveyor rolled strip preferably hot strip in front of a reel known.
  • hydraulic cylinders are used, which are able to apply the required contact pressure in the second step. The hydraulic cylinders cause the displacement of the guide rulers both during the first and during the second step.
  • a control device for the control of the hydraulic cylinder, a control device is provided which advance the guide rulers from a retracted starting position to a predeterminable position during the first step via the hydraulic cylinders arranged downstream of them as actuators.
  • the hydraulic cylinders arranged downstream of them as actuators.
  • at least one of the hydraulic cylinders is both positionally and force-controlled.
  • a device for guiding a metal strip to a reel in which lateral guide rulers are used.
  • lateral guide rulers In the direction of the metal strip a first and a second guide rule are provided on both sides.
  • the positions of the second guide rulers with respect to the metal strip are controlled by position controllers independently of the positions of the first guide rulers.
  • Out JP 2001-047120 A are a generic device according to the preamble of claim 1 and a corresponding method according to the preamble of claim 7 known.
  • this object is achieved in a device of the type mentioned above in that a control device for damping the periodic running of the rolled strip is provided, which can be supplied as input variables in the management of the rolled strip acting forces and / or positions of the guide rulers and / or the rolled strip and that the control device, based on the measured input variables, regulates the positions of the guide rulers and / or forces exerting the side guides on the rolled strip.
  • the control device comprises a controller, to which the forces exerted by the two guide rulers on the rolled strip, can be supplied, and generates from these forces each path signals for the two guide rulers.
  • the essence of the invention is that a device for damping and avoiding the lateral running of the metal strip is provided. This stabilizes the winding process.
  • the side guides or guide rulers are used in the area in front of the winding reel in known catfish. The side guides can be adjusted vertically with respect to the winding tape to adjust their positions to the width of the respective tape to be wound.
  • a differential force is obtained from the respective forces acting on the two guide rulers and then fed to the control device.
  • control device is supplied with the forces of the driver setting on the rolled strip and / or the positions of the driver setting on the rolled strip as input variables.
  • control device is supplied with the measured strip center position of the rolled strip and / or a measured differential pull of the rolled strip, in particular in the region of the reel, as input variables.
  • the controller for the two sides of the rolled strip a first or a second position controller are arranged, wherein the first position controller, the sum of the path signal generated by the controller and the difference between the position setpoint and the actual position of the first guide ruler and the second position controller, the difference from the path signal generated by the controller and the difference between the position setpoint and the actual position value of the second guide rule is fed.
  • the two position controllers respectively generate valve setpoints for hydraulic cylinders for actuating the guide signals or side guides.
  • the invention also relates to a method for laterally guiding a rolled strip transported on a roller table, preferably a hot strip in front of a winding device, with parallel first and second side guides provided on both sides of the rolled strip which are displaced towards or away from each other by adjusting means which are independently adjustable.
  • a metal tape reel 1 ( Fig. 1 ) serves to wind a metal strip 2, in particular a hot strip, by means of a winding device 3, on which the metal strip 2 in the form of a collar 4 is to be wound onto a dome 5.
  • the metal strip 2 is guided over a side guide region 6, pulled by a driver comprising a driver lower roller 7 and a driver upper roller 8, and finally wound on the winding device 3.
  • a periodic lateral running of the rolled strip 2 may occur, ie the metal strip 2 is not wound centrally and edgewise on the winding mandrel 5 of the winding device 3, but deviates laterally from the middle position. For example, periodic deviations from the mean position on the winding mandrel 5 occur.
  • the amplitude of the lateral offset of the metal strip 2 can decay relative to the desired middle position during the winding process (FIG. Fig. 2 ), remain constant during the entire winding process ( Fig. 3 ) or during the winding process ( Fig. 4 ).
  • the metal strip 2 passes over rollers 13 in this area.
  • a controller 14 ( Fig. 6 ), the two force values F SBS of the side guide 11 on the operating side and F SAS of the side guide 12 on the drive side are supplied as input values.
  • the controller 14 obtains from the difference a position value, namely the difference position ⁇ s D.
  • a first position value is obtained, which is summed with the value ⁇ s D and fed to a position controller 15 for the drive side, which generates the valve target value y VAS therefrom to actuate the adjusting cylinder 9.
  • the value ⁇ s D obtained by the controller 14 is subtracted from a second position value generated from the difference between the position command value S BSREF of the side guide 11 and the actual position value S BSACT of the side guide 11.
  • the value generated by the subtraction of the value .DELTA.s D is supplied to an operating position controller 16, which generates therefrom the valve setpoint Y BAS in order to actuate the setting cylinder 10. In this way, an individual regulation of the positions of the two adjusting cylinders 9, 10 is made possible.
