Definitions

  • the invention relates to a method for the production of yarn bobbins in gradual precision winding with constant yarn feed speed and constant bobbin circumferential speed by changing the bobbin ratio in stages, and to a device for the production of yarn bobbins in gradual precision winding with constant yarn feed speed by driving the bobbin on its periphery by means of a drive roller, the peripheral speed thereof is constant for the entire bobbin structure, and the thread is laid using a traversing thread guide, the drive of which is regulated depending on the bobbin speed so that the bobbin ratio is constant over a build-up phase, but this is changed several times over the entire bobbin structure.
  • Rovings, spun yarns and filament yarns are usually produced at a constant delivery speed; this means that the yarns must also be wound at a constant speed.
  • There are systems for this e.g. a spindle with ring and ring traveler or flyer, in which the winding is also associated with a rotation, but also pure winding systems that wind without rotation.
  • pure winding systems two fundamentally different methods of coil construction are used, namely the precision winding and the wild winding.
  • the bobbin speed and the number of double strokes of the traversing thread guide form a fixed ratio, the so-called bobbin ratio.
  • bobbins can be produced in parallel winding, in which the traversing thread guide shifts by the thread size with one turn of the bobbin, or bobbins with more or less strongly crossed layers of yarn.
  • the thread can be wound according to the individual requirements, e.g. position, but you can also distribute the reversal points on the end faces of the bobbin as evenly as possible over the bobbin circumference. Precision-wound coils can therefore be optimally adapted to the special requirements of the material to be wound or its use.
  • the circumference of the coil is driven by a drive roller at a constant circumferential speed.
  • the traversing movement is coupled with the rotation of the drive roller and takes place at a constant frequency. This gives a thread crossing that is dependent only on the ratio of these two sizes and is therefore constant over the entire package build.
  • the wild winding is ideal for winding yarns that are supplied at a constant speed.
  • the winding ratio is constantly changing. In the case of integer values for the bobbin ratio - this is usually the case several times over the bobbin build-up - the yarn is laid on top of one another in several layers in the same turn. This process is also called image or mirror winding. Windings deposited in this way are relatively loose and, particularly with smooth filament yarns, tend to form an unstable bobbin. This can be very difficult when working through the coil due to excessive thread tension, falling or shooting layers, loop formation, etc., which ultimately results in unnecessarily high thread breakages.
  • DE-OS 21 65 045 e.g. describes a winding process and a cross winding machine for wild winding, in which the winding ratio is controlled within non-integer ratios. You can avoid the occurrence of image windings, but you cannot achieve the many possibilities of precision winding.
  • DE-OS 29 14 924 describes a winding device for wild winding, in which the slip of the asynchronous motor driving the traversing device is changed in the vicinity of integral winding ratios in order to avoid image winding. Even with this device, the advantages of precision winding cannot be achieved.
  • a disadvantage of the precision winding is that the winding speed is dependent on the respective winding diameter at a constant spool speed. To even out the bobbin speed, the drive speed of the bobbin is therefore often regulated, for example, as a function of the bobbin diameter. If the yarn is fed at a constant rate to the winding unit, this is a relatively simple type of control too imprecise. It is therefore customary to continuously record the thread tension before winding and thus regulate the bobbin speed.
  • GB-P 999.185 also describes an arrangement in which the peripheral speed of the coil is detected and kept constant by regulating the coil drive.
  • DE-AS 19 13 451 describes a precision cross winder in which the bobbin is circumferential is driven.
  • the spool speed which changes depending on the spool diameter, is recorded and used to control the traversing drive. A predetermined, constant winding ratio is maintained.
  • DE-AS 26 49 780 describes a winding machine for textile yarns in which the bobbin is driven on its circumference by means of a speed-controlled drive roller and the reverse thread shaft in which the traversing thread guide is moved is also speed-controlled. Both speeds are controlled by electronic control circuits and computers, which take into account, among other things, the mathematical relationships between winding speed, peripheral speed of the bobbin or drive roller and thread laying speed, so that the difference between thread speed and winding speed can be specified. With this device, the production of precision bobbins with constant feed speed and constant thread tension when winding is possible. In this case, preprogrammed jumps in the winding ratio can be carried out on the computer in order to avoid unfavorable areas of the cross Avoid angle with full and empty spool.
  • the object of the present invention is to provide an economically working method and a device for producing coils which avoids the known disadvantages.
  • This solution combines the advantage of the wild winding with regard to the technically very simple winding by driving the coil on its circumference at a constant circumferential speed with the possible variations of the precision winding for an optimal coil construction in an economical manner.
  • the circumference of the bobbin (2) is driven by a drive roller (3) at a constant peripheral speed.
  • the speed of the coil changes depending on the coil diameter reached.
  • the drive of the traversing thread guide can e.g. by means of an eccentric, cam, reversing thread shaft, grooved drum or a threaded spindle that changes the direction of rotation.
  • the movement of the traversing thread guide must be controlled so that a complete back and forth movement always corresponds to a constant number of revolutions of the bobbin.
  • the coil speed decreases in accordance with the growing coil diameter. Therefore, the drive of the traversing thread guide must be coupled with the rotation of the bobbin. This is expediently done using an electrical or electronic control system. There are many options available for this today.
  • Fig.2 The basic structure of such a control system is shown in Fig.2.
  • the speed of the coil (2) is recorded analogously by means of a tachometer (5) and entered as a setpoint in the controller (7).
  • the speed of the drive motor (10) is recorded analogously by means of a tachometer (6) and entered as an actual value in the controller (7).
  • the setpoint and actual value are compared with one another in the controller and used to regulate the supply of the traversing thread guide drive (10).
  • a DC motor can be used to drive the traversing thread guide, the controller changing the motor speed in the desired manner via the supply voltage.
  • a synchronous or asynchronous motor with regulation of the frequency of the supply voltage can also be used.
  • the crossing can be kept within limits that are favorable for the coil build-up.
  • This change in the winding ratio must take place in such a way that integral winding conditions are run through faster than a winding game lasts.
  • the cross becomes angle increased.
  • the wind-up speed also increases as a result.
  • the still portable change in the wind-up speed depends to a large extent on the application in question. For example, when winding the yarn on a twisting machine, increasing the winding speed from one winding phase to the next has no influence on the bobbin build-up, since the thread tension practically does not change. The higher wind speed will only reduce the yarn twist. Here would be a change in the wind speed of less than 3% without any adverse effects on the quality. In contrast, an increase in the winding speed will influence the thread tension on a spinning draw frame for high-strength, low-stretch yarns. If this becomes too high, this can be noticeable as a fluctuation in the elongation in the yarn, as well as adversely affecting the uniform package build-up. However, if the change in the wind-up speed is less than 0.3%, this is in the range of other, unavoidable influences and experience has shown that it is of no importance.
  • the amount of the integer part of the winding ratio influences the crossing angle in connection with the coil diameter.
  • the fractional part of the winding ratio is mainly influenced by the displacement of the stroke reversal points on the circumference of the spool.
  • their order should also be as symmetrical as possible in order to avoid a temporal focus.
  • the fractional part of the winding ratio e.g. is 2/5 or 3/5 or 2/7, 3/7, 4 / 7.or 5/7, since then the subsequent reversal point acc. Fig.4 lies approximately on the opposite side.
  • the reversal point moves along the circumference, but is also evenly distributed.
  • the 6th or 8th reversal point must be prevented from falling on the first reversal point. This is achieved by the fact that the set winding ratio in the fractional part deviates slightly from the values mentioned above.
  • the controlled parallel winding with the winding of the yarn layer by layer can be regarded as a special case of the crossed precision winding with the crossing angle 0. A change in the winding ratio is then no longer necessary, since the winding speed and peripheral speed of the coil are identical.
  • a stable coil flank cannot be achieved with a parallel winding. For this reason, the spool assembly must either be between discs or with a shorter stroke. A mechanism that does not change the winding ratio must be used to shorten the stroke.
  • a stepper motor e.g. the reversal of which the direction of rotation is controlled by the coil diameter.
  • a spinning machine for synthetic filament yarns spins at a speed of 3,300 m / min and is wound onto a cross-wound bobbin driven at a constant speed by means of a drive roller.
  • the sleeve diameter of the coil was 85 mm, the diameter of the fully wound coil was 450 mm.
  • the winding stroke was 250 mm.
  • the speed of the coil holder is determined by a tachometer.
  • the traversing movement of the thread guide is generated by a reversing thread which is driven by a direct current motor, the speed of which is also determined by a tachometer. 7 revolutions of the reverse thread shaft generate a double stroke of the traversing thread guide.
  • the crossing angle must not be less than 7 ° and the coil must be built up in a stepwise parallel winding.
  • the analog values of the two speeds are fed to a controller, which regulates the motor supply voltage.
  • the analog value of the motor speed is converted in stages to change the winding ratio.
  • the switchover signal occurs at an engine speed of 5630 rpm, which corresponds to 804 double strokes / min.
  • the jumps in the winding ratio were chosen so that the deviation in the wind-up speed due to the change in the crossing angle is less than 0.3%.
