Definitions

  • the invention relates to a method for winding a thread into a cheese in a wild winding according to the preamble of patent claim 1.
  • a winding process is known, for example, from US Pat. No. 4,245,794.
  • the lay-off angle and the cross-over ratio as well as the thread tension during the winding process are essential factors for the stability of the winding, the avoidance of mirror formation and the good workability of the winding during further processing and transport.
  • the general aim is to avoid deviations from experience-based favorable settings, in particular when suppressing mirror formation, if possible.
  • the thread tension prevailing in the thread during the winding process generally also increases in an undesirable manner as the winding diameter increases, unless measures are taken to counteract an increase in the thread tension.
  • the back and forth movement of the Thread on the bobbin surface during the bobbin travel essentially with a constant traversing frequency, which at essentially constant thread delivery at constant thread lay-off angles leads on the coil surface.
  • the wild winding is there especially distinguished from the precision winding, in which the winding spindle drive and the traversing drive mechanically or electronically in a fixed, non-integer Ratio and the lay angle with increasing coil diameter is steadily decreasing.
  • the invention has for its object the management of the thread tension without influencing the crossing ratio and lay angle to make. This task is accomplished by the in the label part of the specified feature solved.
  • the winding ratio or the K-value which are defined by the ratio of winding spindle speed and traversing frequency - as the number of double strokes - remains unchanged when the thread tension and thus the winding spindle speed change.
  • such a traversing program includes one constant traversing speed.
  • Such one constant predetermined traversing speed can also Fluctuations are superimposed (wobble).
  • the traversing speed does not remain constant, but is between an upper limit and a lower limit changed according to a predetermined law, whereby also the upper limit and the lower limit change during winding change a thread to a package (winding trip).
  • a tolerance range is advantageous for the course of the thread tension given, for example, by targeted experiments or determined by experience from production can be. In particular, it should cover inevitable short-term fluctuations.
  • the nominal value of the thread tension can also be used as a long-term value Averaging can be determined and specified in experiments.
  • the winding method according to the invention is both in one Winding machine can be used with advantage, in which the bobbin drive by a driving roller driven at a constant speed Spool circumference takes place as well with a winding machine that an axle drive motor controlled by a feeler roller for the Has winding spindle.
  • Fig. 1 shows the construction scheme for performing the winding station equipped according to the winding method according to the invention, in which the thread 1 through a winding spindle 5 with feeler roller 24 and direct drive 6 is wound into a cheese 4.
  • the drive shaft 7 of the oscillation 3 also has its own Drive 8. Both drives 6, 8 are via converters 30 and Supply lines 28, 29 guided by a control unit 9. Instead of being driven directly by the motor 6, it is alternatively also known and customary, the cheese 4 on her Circumference driven by a constant circumferential speed To drive the driving roller.
  • the control unit 9 has the task of the drives 6, 8 in mutual To coordinate dependency so that the Crossing ratio and the laying angle with those for the whole Predetermined setpoint curves in accordance being held.
  • Thread tension transducer 2 is provided via a signal line and not one because of the better clarity shown D / A converter (digital-analog / converter) the course the measured thread tension (signal 23) to the control unit 9 transmitted.
  • D / A converter digital-analog / converter
  • Changing the spindle speed also means changing the The traversing speed is such that the specified one The course of the crossing ratio and the lay angle remain unchanged preserved.
  • Both are specified by the fundamental frequency generators 11 (for traversing) and 12 (for spool drive) generated fundamental frequencies and the setpoint curve 20 of the Thread tension.
  • the generators 11, 12 generate the corresponding setpoints 18, 19 specified by the winding program respective basic frequencies for the coil drive and the traversing drive, which of the winding head control belonging to the control unit 9 14 are supplied.
  • a disturbance generator 13 provided that the generation of the setpoint 18 of the traversing signals to be given for the intended interference procedure (e.g. B. wobble) serves to suppress the mirror image.
  • a winding device with a directly driven winding spindle (Fig. 1) belonging to Fig. 3 is also in that of the fundamental frequency generator 12 leading to connection S of the winding head control 14 Line a spindle drive control 17 is provided.
  • the winding head control 14 are continuously determined Actual values, namely 21 of the oscillation 3 (double stroke rate, oscillation frequency), 22 of the winding spindle speed and 23 of the thread tension and in the embodiment according to FIG. 3 also by the feeler roller 24 determined coil circumferential speed (signal 25), fed.
  • the actual values go to a control unit 9 belonging unit 16 for actual value acquisition, the Actual value signal 23 of the thread tension to a control unit 15 for the thread tension is passed on.
  • the control unit 15 Correction signals generated pass through line 26 to Connection S (winding spindle) of the control 14 and via the line 27 to the interference generator 13 and from there together with the interference signals to the CH connection of the winding head control 14 both inputs of the controller 14 from the fundamental frequency generators 11, 12 generated signals by multiplicative evaluation with the same evaluation factor depending on the thread tension modified.
  • FIG. 1 to 3 described method for controlling the drives 6,8 a winding spindle 5 and the traversing 3 assigned to it on a winding device with several, on a reel turret arranged winding spindles is applicable, the winding spindles likewise either by a direct drive 5 according to FIG. 3 or a friction roller drive according to FIG. 2 can be driven.
