Definitions

  • the invention relates to a method for winding cross-wound bobbins in a wild winding on a winding machine, the winding stations one each using a friction drive to drive a package Winding drum included and to avoid Image windings in possible image zones Slip between cheese and produce winding drum, the diameter of the Cross-wound bobbin from the known diameter of the winding drum and the measured speeds of the winding drum and Cheese is calculated.
  • the cheese is mounted in a swiveling spool frame and pressed onto the winding drum with a contact pressure.
  • DE 198 29 597 A is disclosed for generating a Slip when passing through image zones to lower the contact pressure, what alone or in connection with that Switching the motor on and off can be carried out.
  • the package is changed depending on a desired thread length it should be relatively easy.
  • the slip plays here not a decisive role and can possibly still about correction factors that take into account the result the speed sensor of the winding drum, for example one Incremental counter to adjust the size of the slip.
  • the invention has for its object a method of to improve the type mentioned so that a possible exact diameter detection is also possible in image zones and that it is also possible with a given diameter switch off the package.
  • This object is achieved in that the current Diameter of the package when passing through one Image zone the expected course of the increase in diameter calculated and that when passing through the image zones resulting diameter increases to that before reaching the image zone from the speed ratio of the package and winding drum and the diameter of the winding drum Diameter of the package can be added.
  • Another development of the invention provides that the course of the increase in the diameter of the cheese from the ratio of wound thread length and calculated diameter is calculated and that during the Passing through an image zone the wound thread length is detected becomes.
  • the wound one Thread length by detecting the revolutions of the winding drum determined. It is assumed that the per revolution length of thread or thread length conveyed by the winding drum is known. If with this solution while driving through an image zone the nominal diameter of the package is reached is, this results from that before the image zone is reached calculated diameter and a predeterminable number of revolutions of the winding drum.
  • the cheese is used from the expected course of the increase determined diameter. In this way, the assignment can be incorrect or incorrect Diameter information for such packages be avoided. This is also an advantage if the Change of the package depending on a desired thread length is carried out.
  • the output of the diameter can be printed out respectively. There are further output options in the Display on a display or by means of a monitor.
  • the drawing shows a largely schematic representation the upper area of a winding unit with the associated one Control.
  • One winding machine has several largely independent of each other working winding units, at each one Cheese 10 is wound. On the cheese 10 is a Thread 11 wound in the direction of arrow 12 by one spinning bobbin, not shown, is withdrawn. The amount of thread several spinning bobbins is combined to form a cheese 10.
  • the cheese 10 is by means of a winding drum 13 Friction driven.
  • the cheese 10 is with its bobbin tube 14 between coil plates 15, 16 of the arms of a coil frame held about a to the axis of the winding drum 13th parallel axis is pivotally mounted.
  • the winding drum 13 has a so-called reverse thread groove provided, by means of which the running thread 11 in the transverse direction is laid in a so-called wild winding.
  • On the Path to the winding drum 13 passes through the thread 11 electronic thread cleaner 17, a separator 18 and a thread guide 19.
  • the thread 11 checked for errors (thick and thin), which at Exceeding specified 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 which transmits these values with predefined values for example in the winding station computer 20 from a central Machine computer entered, compares. With impermissible Deviations, the separator 18 is actuated.
  • the thread piece with the impermissible thread error is known in Disconnected from the thread, then - controlled from the winding unit computer 20 - again a thread connection manufactured and the winding process is resumed.
  • the winding drum 13 is driven by an electric motor 21, its speed by means of a frequency converter 22nd is specified.
  • the winding drum 13 is a speed sensor assigned, which is connected to the winding unit computer 20 is.
  • the speed sensor consists, for example, of a magnet wheel 23 and a Hall sensor 24. Furthermore, the speed the cheese 10 is detected and in the winding unit computer 20 entered.
  • a magnet wheel is on the coil plate 16 25 attached to which a Hall sensor 26 is assigned.
  • the winding station computer 20 like that with the input 27 is indicated, common working conditions for all winding units predefined by means of a machine computer. These are for example the winding speed, i.e. the speed of the Winding drum 13, the tolerances for the thread cleaner 17 and if necessary also the values to which a not shown Voltage regulator to be set, which the Regulates winding tension. If the contact force between the package 10 and winding drum 13 is controlled, so will for this the basic setting is specified by the machine computer. The winding station computer 20 in turn then varies the operation of the winding unit concerned depending on the respective working conditions there, for example from the unwinding state of the spinning bobbin and from the winding state or the size of the package 10 or the like.
  • a picture disturbance by means of slip to reach between the winding drum 13 and the cheese 10, is also possible, the system pressure of the package 10 to change on the winding drum 13, including the coil frame with a loading device, not shown can be provided, which is controlled by the winding unit computer 20 and the contact force between the cheese 10 and winding drum 13 sets.
  • the winding unit computer 20 Based on the data from the speed sensor 23, 24 of the winding drum 13 and the speed sensor 25, 26 of the cheese 10 the winding unit computer 20 utilizing the known Diameter of the winding drum 13 the current diameter the package 10 at any time. That way it is possible to determine the achievement of a given diameter and when this diameter of the package is reached 10 to perform a bobbin change, for example the winding unit is switched off, i.e. the drive motor 21 is stopped. This makes it possible at all winding positions a winding machine cross-wound bobbins 10 with the same diameter to produce.
  • the winding unit calculator calculates 20 in a slip-free zone, how much yarn length is required is to the diameter of the cheese by a predetermined To increase the unit of measurement, for example by one millimeter. This is done in such a way that the diameter of the Cross-wound bobbin 10 continuously due to the speed ratio and the known diameter of the winding drum 13 is calculated , the yarn length being determined at the same time, the is needed so that the diameter of the package 10 by one Unit of measure increases, for example by one millimeter.
  • the wound yarn length can then be used in the image zone Counting the revolutions of the winding drum. It is then possible to advance the diameter of the cheese 10 To reach the image zone in the slip-free phase exactly and then determine how many revolutions of the winding drum 13 are still needed, so that the target diameter the cheese 10 is reached. If the ratio of thread length to increase the diameter of the package 10 is calculated shortly before reaching the image zone then possible errors relatively small. However, it can also take into account that as the diameter increases the cheese 10 the ratio of thread length changes to increase the diameter.
  • the diameter is output as a printout using the printer 28 performed. Alternatively or additionally, the Output in a manner not shown as a display on a Display or using a monitor.
