Definitions

  • the invention relates to a method for winding a thread into a cheese in a wild winding.
  • the lay-off angle and the cross-over ratio, as well as the course of 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 settings which are favorable according to experience, in particular also when suppressing mirror formation.
  • the thread pulling force 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 takes place at a constant traversing frequency during the bobbin travel, which leads to constant bobbin winding on the bobbin surface with essentially constant thread delivery.
  • the wild winding is differentiated in particular from the precision winding, in which the winding spindle drive and the traversing drive mechanically or
  • REPLACEMENT LEAF is electronically in a fixed, non-integer ratio and the deposit angle decreases continuously with increasing coil diameter.
  • a thread tension transducer and a rotating pulsation device controlled as a function of the traversing speed are provided between the thread delivery godet and the input of the traversing.
  • the pulsation device should essentially compensate for the thread tension fluctuations caused by the chanting by deflecting the thread out of its straight run in both directions synchronously with the traversing.
  • the thread tension transducer provided in the thread run in front of the pulsation device is intended, in particular, to convert thread tension force changes caused by the increase in the bobbin diameter into control pulses for influencing the spindle speed in such a way that an increasing thread tension force is counteracted by lowering the spindle speed and vice versa.
  • the invention is based on the task of guiding the thread tensile force without influencing the crossing ratio and the laying angle. This object is solved by claim 1.
  • 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 contains a constantly predetermined traversing speed.
  • a constantly predetermined traversing speed can also be used as a constantly predetermined traversing speed.
  • the traversing speed does not remain constant, but is changed between an upper limit and a lower limit according to a predetermined law, the upper limit and the lower limit also changing during the winding of a package (winding travel).
  • Critical winding-up situations are basically those in which the traversing frequency and the spindle speed form an integer or an integer fractional ratio. These events are called “mirror formation”.
  • the so-called “mirror” not only represents a considerable disturbance of the bobbin structure, but can also lead to the interruption of the winding process and to the destruction of the dishwasher due to out-of-roundness.
  • the invention avoids such unpredictable winding conditions.
  • a tolerance range is advantageously specified for the course of the thread tensile force, which can be determined, for example, by targeted tests or by empirical values from production. In particular, it should cover the inevitable short-term fluctuations resulting from the traversing.
  • the nominal value of the thread tension can also be determined and specified as a long-term value by averaging in experiments.
  • the winding-up method according to the invention can be used with advantage both in a winding-up machine in which the bobbin is driven by a drive roller on the circumference of the bobbin driven at a constant speed, and in a bobbin-winding machine which has an axle drive motor for the winding spindle which is controlled by a sensing roller.
  • FIG. 1 shows a diagram of a winding unit equipped according to the invention with a directly driven winding spindle;
  • Fig. 2 functional diagram of a winding unit with the drive
  • FIG. 3 functional diagram of a winding unit with direct drive of the winding spindle.
  • Fig. 1 shows the construction diagram of a winding unit equipped for carrying out the winding method according to the invention, in which the thread 1 is wound up to a cross-wound bobbin 4 by a winding spindle 5 with sensing roller 24 and direct drive 6.
  • the drive shaft 7 of the oscillation 3 also has its own drive 8. Both drives 6, 8 are guided by a control unit 9 via converters 30 and supply lines 28, 29. Instead of being driven directly by the motor 6, it is alternatively also known and customary to drive the cross-wound bobbin 4 on its periphery by a drive roller driven at a constant peripheral speed.
  • the control unit 9 has the task of coordinating the drives 6, 8 with one another in a mutual dependency such that the crossing ratio and the laying angle correspond to those for the entire
  • REPLACEMENT LEAF predetermined winding of the setpoint values can be kept in agreement.
  • a thread tension force transducer 2 is provided, which is connected via a signal line and a D / A converter (digital-analog / converter), not shown for better clarity, transmits the course of the measured thread tension (signal 23) to the control unit 9.
  • the signals coming from the thread tension sensor 2 in the control unit 9 modify the predetermined setpoints for guiding the drives 6, 8 in such a way that the change in the spindle speed required to compensate for thread tension deviations is accompanied by a change in the traversing speed in such a way that that the predetermined course of the crossing ratio and the laying angle remains unchanged.
  • FIGS. 2 and 3 correspond in substantial parts and are therefore provided with the same reference numerals for the comparable units.
  • the generators 11, 12 generate the respective basic frequencies for the bobbin drive and the chaning drive, which are supplied to the bobbin head control 14 belonging to the control unit 9, in accordance with the desired values 18, 19 specified by the winding program.
  • a disturbance generator 13 is provided, which is used to generate the signals to be given to the setpoint 18 of the oscillation for the intended disturbance method (e.g. wobble) serves to suppress the mirror image.
  • a spindle drive control 17 is also provided in the line leading from the fundamental frequency generator 12 to the connection S of the winding head control 14.
  • the winding head control 14 receives the continuously determined actual values, namely 21 the traverse 3 (double stroke rate, traversing frequency), 22 the winding spindle speed and 23 the thread tension, and in the embodiment according to FIG. 3 also the bobbin circumferential speed determined by the feeler roller 24 (signal 25 ).
  • the actual values arrive in a unit 16 belonging to the control unit 9 for actual value detection, the actual value signal 23 of the thread tension being passed on to a control unit 15 for the thread tension.
  • the correction signals generated in the control unit 15 pass via the line 26 to the 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 connection CH of the winding head control 14 the controller 14 modifies the signals generated by the fundamental frequency generators 11, 12 by multiplicative evaluation with the same evaluation factor as a function of the thread tension.
  • a regulation 17 for the winding spindle drive is provided.
  • the signals coming from the actual value detection 16 and belonging to the actual values 22 (winding spindle speed) and 25 (sensing roller) are fed into the control 17, the actual value signal 22 of the winding spindle speed also arrives just like the actual value Signal 21 of the traversal to the interference generator 13.
  • the power supplied to the drives 6, 8 via the converter 30 is modified in the winding head control 14 in such a way that the actual value profile of the thread tension is adapted to the target value profile without disturbing the predetermined crossing ratio and the laying angle.
  • the method for controlling the drives 6, 8 of a winding spindle 5 and the traversing mechanism 3 assigned to them can also be applied to a winding device with a plurality of winding spindles arranged on a spindle turret, wherein the winding spindles can also be driven either by a direct drive 5 according to FIG. 3 or a friction roller drive according to FIG. 2.

Abstract

La présente invention décrit un procédé pour l'enroulement d'un fil (1), livré à vitesse constante par un dispositif d'alimentation, en une bobine croisée (4), les entraînements (6, 8) pour la brochette de bobine (5) et le dispositif d'ensouplage croisé (3) étant commandés par des convertisseurs de fréquence (30) en fonction d'une commande de la tête de bobine (14). A cet effet, la variation de la vitesse de rotation se fait, en fonction de l'augmentation du diamètre de la bobine, également en fonction d'un détecteur de la force de traction du fil (2). La correction de la fréquence d'alimentation des entraînements (6, 8) se fait de telle sorte qu'un angle de dépôt prédéfini soit respecté sur la bobine (4) et que la force de traction du fil suive un tracé prédéfini.
