  • Method and control device for operating a strip treatment plant for processing a strip for processing a strip, in particular a metal strip or rolled stock
  • the invention relates to a method for operating a strip treatment plant for processing a strip, in particular a metallic strip or rolled stock.
  • the invention also relates to a control device for operating a strip treatment plant for processing a strip, in particular a metallic strip or rolled stock.
  • the strip in particular a metal strip or rolling stock
  • the strip delivered in rolls of material so-called coils
  • the processed strip can be rewound into a coil to simplify transport.
  • the treatment system comprises a number of consecutive strip running control devices spaced apart from one another along the transport direction.
  • the distance between the strip running control devices of a strip treatment plant can be several hundred meters, for example 300 to 500 m, with the strip running control devices typically being independent of one another.
  • the tape running control devices are used to keep the tape in the middle of the transport rollers transverse to the transport direction, or another fixed position transverse to the transport direction. This ensures that the strip is treated evenly by the treatment system and damage to the strip or the treatment system is avoided.
  • the strip running control devices are therefore designed to detect and adjust the position of the strip transversely to the direction of transport.
  • the strip running control devices each comprise sensors for determining the position of the strip transversely to the transport direction and actuators for adjusting the position of the strip transversely to the transport direction.
  • the sensors detect one or both lateral edges of the strip.
  • inductive measuring frames or image sensors including image evaluation are known from the prior art.
  • the actuators are designed, for example, as swiveling rollers, which transfer a movement component to the belt transversely to the main transport direction.
  • the sensors and actuators of a strip running control device are connected to a control logic which controls the actuators on the basis of the sensor data.
  • the strip running control devices thus detect the position of the strip in the strip treatment system, in particular transversely to the transport direction, in each case by means of the sensors. From the sensor data, the logic calculates a deviation of the belt from the target position, usually the center of the transport rollers transverse to the transport direction, and uses the actuators to correct the position of the belt transverse to the transport direction.
  • a corresponding strip running control device is disclosed, for example, in WO 2009/030388 A1.
  • a further problem in the state of the art exists in the case of rolled products with larger defects transverse to the longitudinal direction of the strip, also known as strip sabers. If the strip runs in this way transversely to the longitudinal direction, there will be a large deviation from the desired strip position up to the next strip-running control device. Since the nominal tape position is usually in the center of the tape transport rollers, depending on the direction of the error transverse to the longitudinal direction, it can occur in both directions transverse to the center of the tape transport rollers. In order to be able to compensate for such errors, the width of the transport rollers and, if necessary, the clear passage width of the strip treatment plant is correspondingly increased in the prior art. Since strip treatment lines can be several hundred meters long, this results in considerable additional costs.
  • errors can occur during the treatment of the tape if the tape is not in the desired position during treatment, in particular in the center of the transport rollers. This is particularly the case with inline skin-pass systems, coaters, heat treatment devices or trimming shears.
  • the invention is based on the object of providing a method and a control device for operating a strip treatment plant for processing a strip, in particular a metallic strip or rolling stock, which counteracts the negative effects of both rapid changes in the strip shape, such as so-called dog-legs in the area of weld seams, as well as larger defects transverse to the longitudinal direction of the strip, such as so-called strip saws, and thus damage to the strip and the strip processing system is prevented, accidents are avoided and the manufacturing costs of the strip processing system are also reduced.

  • the sensors detect one or both lateral edges of the strip.
  • the inductive measuring frames or image sensors known from the prior art, including image evaluation, can also be used.
  • the sensor data is used to detect when the The vertical position of the tape changes transversely to the transport direction, which corresponds to a dog-leg of the tape.
  • a so-called tape saber is detected when the position of the tape changes slowly and continuously at right angles to the transport axis. Irregularities in the strip that affect the position of the strip transversely to the direction of transport are thus detected.
  • the first strip-running control device will perform a control intervention on the basis of the sensor data and correct the position of the strip transversely to the transport axis by means of the associated actuators of the strip-running control device. In the case of a dog leg, this can lead to abrupt changes which can possibly have a negative effect on the strip and/or the strip treatment system, in particular the corresponding strip running control device. Since there is usually a certain distance between the sensor and the actuator of the strip-running control device and constant changes, such as with a strip saber, are always associated with a control delay, the strip initially runs out of the strip target position, i.e.
