Definitions

  • the invention relates to a method for controlling pressure rollers which can be displaced by pressure-actuated cylinders when winding tapes in reel systems, the beginning of the tape of the incoming tape being detected and tracked as it rotates around the reel mandrel and its respective position is used to position the pressure rollers, and the pressure rollers in each case the run-in of the beginning of the band and before the start of the next winding position are raised in such a way that the gap formed between the pressure roller and the reel mandrel exceeds the thickness of the already entered band by an amount exceeding the band thickness, and the pressure roller after passing the beginning of the band from this position against the reel mandrel is lowered in the active position.
  • Such a control device has become known, for example, from DE-PS 33 18 031.
  • the beginning of the tape is pressed onto the tape reel by means of pressure rollers, in order to keep damage to the tape and on the pressure rollers as small as possible, before the passage of a step caused by the beginning of the tape, the pressure rollers become larger than the n -spaced by a thickness of the strip, where n is the number of layers of the strip to be wound that have already been applied to the reel mandrel in the area of the respective pressure roller corresponds.
  • step control This control method has become known as "step control”.
  • Step-Control can no longer convince when winding thin tapes.
  • the pressure rollers which are switched to pressure, press the thin strip into the recesses that occur between the segments of the strip reel when the reel mandrel is spreading, as a result of which the strip receives undesired markings. Large parts of the beginning of the band are rejected.
  • the pressure rollers are heavily loaded each time they sink into the recesses between the individual segments, as a result of which the pressure rollers are subject to great wear and considerable noise pollution. Due to the restless position of the pressure rollers on the reel, the adjustment devices for the pressure rollers are also excessively stressed.
  • the invention has for its object to improve existing methods for controlling pressure roller which can be displaced by pressure-actuated cylinders when winding tapes in reel systems to the effect that the aforementioned disadvantages do not occur even when winding tapes of small thickness.
  • the gap formed between the pressure roller and the reel mandrel in the operative position is set at least to n times the strip thickness, that preferably from the beginning of the second layer by spreading the reel mandrel, a slip-free system of Band is brought about on the reel mandrel, wherein the pressure rollers are spaced from the mandrel during the spreading movement of the reel mandrel by the amount of radial movement of the reel segments.
  • the gap formed in the winding direction decreases in the tape entry direction from the pressure roller to the pressure roller and that the respective desired value of the gap formed between the pressure rollers and the reel mandrel is dimensioned such that the pressure rollers can deflect incoming tape, but no radially directed forces against the surface of the reel mandrel.
  • the pressure rollers are brought into the operative position in this way, it is ensured that the gap between the respective pressure rollers and the coiler mandrel is set exactly to the strip thickness or slightly larger than the strip thickness.
  • the pressure rollers which are only used as guide rollers here, move the strip as close as possible to the reel mandrel, but can no longer press it into the recesses between the individual segments. As a result, the tape is not marked.
  • the spreading movement of the reel mandrel ensures that the strip comes into contact with the reel mandrel quickly and without slippage.
  • the above-mentioned object can also be achieved in that an operative position is provided for the last pressure roller in the tape entry direction, which is slightly less than n times the tape thickness, that an action is provided for the penultimate pressure roller in the tape inlet direction that is greater than / equal to the n -fold the strip thickness is that for the pressure rollers arranged in front of the last two pressure rollers in the strip entry direction, effective positions are provided which are n times the strip thickness exceed a surcharge, that the surcharge increases from the pressure roller to the pressure roller opposite to the direction of tape entry, and that preferably from the beginning of the second layer, by spreading the reel mandrel, a slip-free contact of the tape on the reel mandrel is brought about, the pressure rollers during the spreading movement of the reel mandrel by the amount of radial movement of the reel segments are spaced from the mandrel.
  • These predetermined operative positions of the pressure rollers ensure that only one pressure roller presses the tape against the reel mandrel with minimal force, and that the other pressure rollers brought into the active position form an inlet funnel which brings the tape as close as possible to the reel mandrel and applies it.
  • the height of the position decreases from the pressure roller to the pressure roller before the beginning of the tape start or before the start of the next winding position in the direction of the tape.
  • an inlet funnel is formed as soon as the strip is fed in, through which the strip is optimally guided to the coiler mandrel. The activation of the pressure rollers narrows this funnel even further.
  • the pressure rollers are brought into the raised position and force-controlled into the operative position. It is appropriate here if the force control loop is preferably proportionally controlled, if the force setpoint specification corresponds to the tape guide force and if the actual value of the position control loop is set as a base value upon reaching the specified tape guide force, to which the next jump to the raised position as a new total Setpoint is added.
  • the actual value of the position control loop is set for each newly set gap between the pressure roller and the reel mandrel as soon as the force setpoint and the actual force value are the same as the base value to which the next jump is added. so that, even in the case of multiple folds, the jump height of the pressure rollers which follow the pressure roller which has passed the first multiple folds can be raised again to the predefined setpoint of the belt.
  • the position of the strip start is continuously determined by means of a strip tracking system, that the strip tracking system is started by an accelerometer and / or a load cell at the output driver of the rolling line upstream of the reel or by a switch that detects the strip start without contact is synchronized by means of accelerators and / or force gauges arranged on the pressure rollers from the incoming belt and that the position of the beginning of the belt is calculated from the peripheral speed of the driving roller from the belt thickness and the geometric dimensions of the reel system.
  • the coiler mandrel is spread in a position-controlled manner and that the position control loop takes the measure for the radial spacing of the pressure rollers from the coiler mandrel.
  • the figure shows an open driver 1, which is followed by a guide, not shown, for the tape 2 in the tape running direction.
  • a contact-free switch 3 for example a light barrier or a nozzle / baffle plate system, is also arranged behind the driver 1 in the direction of travel of the tape.
  • the reel mandrel 4 are assigned pressure rollers 5, 6, 7 and 8.
  • the pressure rollers 5, 6, 7, 8 are via hydraulic cylinders 9, 9 ', 9'',9''' can be brought into the raised position or in the operative position.
  • the hydraulic cylinders 9, 9 ', 9',9''' have dynamometers 10, 10 ', 10'',10''' and position sensors 11, 11 ', 11'',11'''.
  • control system The function of the control system according to the invention is described below. All the dimensions of the reel system that are necessary for the calculation of the position of the strip start are stored in the computer of the strip tracking system, not shown. Only the strip thickness of the strip 2 to be wound is entered into the computer.
  • the pressure rollers 5, 6, 7, 8 are set to their position shown in the figure, in which the gap between the respective pressure rollers 5, 6, 7, 8 and the reel mandrel 4 is larger than the strip thickness by an amount stored in the computer, the gap decreasing in the tape entry direction from the pressure roller to the pressure roller and for the pressure roller 5, for example, corresponds to 2.5 times the strip thickness.
  • the belt speed can be derived from the peripheral speed of the drive rollers.
  • the force pulse determined via the dynamometer 10 is used to synchronize the calculated and the actual position of the beginning of the band.
  • the beginning of the band is bent towards the pressure roller 6 via this deflection shell. Accordingly, the beginning of the tape continues to be bent to roll 7 and roll 8.
  • the pressure roller 5 is moved by means of of the cylinder 9 for the second winding position in a position-controlled position is brought into the active position.
  • the pressure rollers 6, 7, 8 are brought into the operative position in a force-controlled manner.
  • the force setpoints increase from the pressure roller to the pressure roller in the direction of tape entry, but the force setpoints are never set such that contact forces act on the reel mandrel 4.
  • the coiler mandrel 4 is spread over a position control loop 12.
  • the pressure rollers 6, 7 and 8 are correspondingly lifted off and brought back into the active position when the second turn is wound up.
  • the active position and the raised position of the pressure rollers 5, 6, 7, 8 are each corrected by the amount that the reel mandrel while the second winding is spread.
  • one of the force gauges 10, 10 ', 10'',10''' measured a peak force. If this peak force exceeds predetermined threshold values, the pressure rollers are spaced from the coiler mandrel depending on the level of the exceeded threshold value. Will be on the next one in the winding direction Pressure roller again measured a force peak, so the pressure rollers 5, 6, 7, 8 are completely swung away from the reel mandrel.
