Definitions

  • the invention relates to a method for winding cheeses in wild winding on a winder whose winding units each one driving a cheese by means of friction Winding drum included and to avoid image windings in possible image zones slip between cheeses and winding drum produce, wherein the diameter of the cheese from the known diameter of the winding drum and the measured speeds of the winding drum and the cheese is calculated.
  • DE 196 25 510 A discloses a method and a Device that determines the slip in image zones to serve in the production of coils without that additional transducers must be used.
  • the de 196 25 510 Al is based on a special drive, at which at regular intervals slip phases and Leaving phases alternate during the entire coil travel. In this drive, the drive motor is engaged at intervals switched off, as can be seen in Figs. 3 and 4. During the switch-on interval, the coil slows down accelerated as the winding roller, since slippage between coil and winding roller is present.
  • DE 196 25 510 A describes that in a phasing out the course of the Increase of the coil radius is calculated.
  • the diameter calculation for example used to change the time of the cross-wound bobbin against a determine empty sleeve diameter-dependent.
  • the change of the cheese against an empty sleeve depending on the wound thread length is the wound thread length determined by counting the revolutions of the winding drum, the with the promoted during a turn, known thread length be multiplied.
  • Creating slip in possible Picture zones is turned on and off by a Winding drum driving motor causes. Within one given bandwidth of the speed is the speed of Winding drum by switching on the engine relatively quickly increased from the lower limit to the upper limit, after which then the engine is switched off again until the lower limit is reached. During acceleration of the engine arises Slip.
  • the cross-wound bobbin is mounted in a pivoting creel and pressed with a contact pressure to the winding drum.
  • DE 198 29 597 A is disclosed for producing a Slippage when driving through image zones to lower the bearing pressure, alone or in conjunction with the On and off the engine can be performed.
  • the change of the cheese depending on a nominal thread length should, so that's relatively easy.
  • the slip plays here not crucial and may possibly also be taken into account via correction factors that the result the speed sensor of the winding drum, for example a Incremental counter to clean up the amount of slippage.
  • the invention has for its object to provide a method of to improve the type mentioned above so that a possible accurate diameter detection is also possible in image zones and that it is also possible with a given diameter the cheeses off the winding unit.
  • the course of the increase in the diameter of the cheese is calculated over time and that while driving through an image zone the time is detected.
  • About the recorded time span can thus be relatively accurate to that at this time be closed present diameter of the cheese. It is then possible to specify a period of time during which the Nominal diameter is expected and after this period to turn off the winding unit.
  • the course of the increase in the diameter of the cheese from the ratio of wound thread length and calculated diameter and that during the Passing through an image zone detects the wound thread length becomes.
  • the wound up Thread length by detecting the revolutions of the winding drum determined. It is assumed that the per revolution the winding drum promoted yarn length or thread length is known. If this solution while driving through reaches an image zone of the target diameter of the cheese is, this results from the before reaching the image zone calculated diameter and a predictable number of turns of the winding drum.
  • An image zone finished cheese serves the from the expected diameter of the increase. In this way, the assignment may be inaccurate or error prone Diameter information in such cheeses be avoided. This is also advantageous if the Changing the cross-wound bobbin depending on a nominal thread length is carried out.
  • the output of the diameter can be expressed as an expression respectively.
  • Other output options exist in the Display on a display or via a monitor.
  • the drawing shows a largely schematic representation the upper part of a winding unit with the associated Control.
  • a winder has several largely independent of each other working winding units, to each one Cross-wound bobbin 10 is wound.
  • the cheese 10 is by means of a winding drum 13 by means Friction driven.
  • the cross-wound bobbin 10 is with its bobbin tube 14 between Spuleellern 15, 16 of the arms of a creel held around the axis of the winding drum 13 is mounted pivotably parallel axis.
  • the winding drum 13 is provided with a so-called Kehrgewinderille provided by means of the incoming thread 11 in the transverse direction laid in so-called wild winding.
  • the thread 11 passes through a electronic thread cleaner 17, a separator 18 and a thread guide 19.
  • the thread 11 checked for errors (thick spots and thin spots), which at Exceeding predetermined tolerances cleaned out of the thread become.
  • the determined by the thread cleaner 17 Values of the thread 11 are sent to a winding station computer 20 transmitted these values with predetermined values, the For example, in the winding station 20 of a central Machine computer to be entered compares. Inadmissible Deviations, the separator 18 is actuated.
  • the thread piece with the improper thread error is known Way out of the thread, after which - controlled from the winding station 20 - again a thread connection made and the winding process is resumed.
  • the winding drum 13 is driven by means of an electric motor 21, its speed by means of a frequency converter 22nd is given.
  • the winding drum 13 is a speed sensor assigned, which connected to the winding station computer 20 is.
  • the speed sensor consists for example of a pole wheel 23 and a Hall sensor 24. Furthermore, the speed the cross-wound bobbin 10 detected and in the winding station computer 20 entered.
  • a magnet wheel is on the reel plate 16 25 attached, which is associated with a Hall sensor 26.
  • the winding station 20 as with the input 27th is indicated, common working conditions for all winding units predetermined by a machine computer. These are for example, the winding speed, i. the speed of the Winding drum 13, the tolerances for the thread cleaner 17 and possibly also the values to which a not shown Voltage regulating device is to be set, which is the Winding tension regulates. If the contact force between cheese 10 and winding drum 13 is controlled, so will For this purpose, the default setting specified by the machine computer. The winding station computer 20 then varies the operation of the relevant winding unit depending on the respective existing working conditions, for example from the unwinding state of the bobbin and the winding state or the size of the cheese 10 or the like.
  • he determines a so-called picture disorder, by which Image windings avoided in previously known possible image zones become.
  • the winding station computer the motor 21 constantly between tolerance limits on and off, whereby when reaching the lower tolerance limit the engine 21 is turned on and accelerated so much is that a slip between winding drum 13 and Cheese 10 is formed, after which he reaches the top Tolerance limit is turned off, so that the speed or Angular velocity of the winding drum 13 together with the then without slip driven cross-wound bobbin 10 to the lower tolerance limit drops.
  • the system pressure of the cheese 10 on the winding drum 13 to change what the creel with a loading device, not shown can be provided, which is controlled by the winding station computer 20 is and the bearing force between cheese 10 and winding drum 13 determines.
  • the winding station 20 Based on the data of the speed sensor 23, 24 of the winding drum 13 and the speed sensor 25, 26 of the cheese 10 can the winding station 20 using the known Diameter of the winding drum 13 the current diameter the cross-wound bobbin 10 at any time. That's the way it is possible to detect the reaching of a given diameter and upon reaching this diameter of the cheese 10 perform a bobbin change, including, for example the winding unit is switched off, i. the drive motor 21 is stopped. This makes it possible at all winding units a winder cheeses 10 of the same diameter to produce.
  • winding station calculator calculates 20 in a slip-free zone, how much yarn length is needed is to the diameter of the cheese to a predetermined To increase the unit of measurement, for example by one millimeter.
  • the Output of the diameter is expressed as an expression by means of the printer 28 performed. Alternatively or additionally, the Output in a manner not shown as an indication on one Display or by means of a monitor.
