Definitions

  • the invention relates to a method for winding yarns or tapes continuously fed at a constant speed to a winding device in a gradual precision winding, and to a winding device for carrying out the method.
  • 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 such as a spindle with ring and ring traveler or flyer, in which the winding also involves a rotation, but also pure winding systems that wind up without rotation. With the 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 in parallel winding in which the traversing thread guide shifts by the thread size by one turn of the bobbin, or bobbins with more or less strongly crossed layers of yarn can be produced.
  • the yarn can be tailored according to individual requirements, e.g. Layer to layer wound, but you can also distribute the reversal points on the end faces of the coil as evenly as possible over the coil 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 lead to great difficulties when processing the bobbin due to excessive thread tensile forces, falling or shooting layers, loop formation, etc., which in the end results in unnecessarily high thread break counts.
  • 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.
  • the drive speed of the bobbin e.g. regulated depending on the coil diameter. Given the constant speed at which the yarn is delivered to the winding unit, this relatively simple type of control is 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 coil is driven on its circumference.
  • 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 include take into account the mathematical relationships between winding speed, peripheral speed of the bobbin or drive roller and thread laying speed, regulated in such a way that the difference between thread speed and winding speed can be specified.
  • the production of precision bobbins with constant feed speed and constant thread tension during winding is possible.
  • preprogrammed jumps in the winding ratio can be carried out on the computer in order to avoid awkward areas of the crossing angles when the bobbin is full and empty.
  • the technical effort for these computer-controlled speeds of the drive roller and the reverse thread shaft is correspondingly high. An economically sensible application 5 of the device described is thus significantly burdened.
  • a method and a winding device are known from Japanese laid-open specification 65 628.
  • the circumference of the bobbin is driven by a drive roller.
  • a detector is connected to the drive roller drive motor, which detects the loading torque of the drive motor and controls the coil drive motor via a control unit.
  • Another detector records the speed of the traversing thread guide and feeds a corresponding output signal to a control circuit, which also records the output signal of the bobbin detector, which is dependent on the speed of the bobbin.
  • the control circuit is programmed in the sense of a step-by-step precision winding and gives a control signal to the drive motor for the traversing thread guide when the winding ratio changes.
  • the limits for the change in the winding ratio are determined such that a maximum oscillation frequency predetermined by the mechanical load-bearing capacity of the oscillation drive is not exceeded and the minimum oscillation frequency determined by the minimum crossing angle required for sufficient coil cohesion is not undershot.
  • the thread tension is continuously measured and the switchover time from a bobbin ratio to the next fixed bobbin ratio selected so that the bobbin tension ranges from 0.05 to 0.5 g / who doesn't leave.
  • the necessary continuous measurement of the thread tension affects the yarn quality particularly at high winding speeds.
  • considerable technical effort is required for the exact determination of the very low thread tension, which is customary when switching.
  • the measures described here can only have an insignificant influence on the maximally occurring thread tensile forces and thus also their adverse influence on the quality of the yarn and the bobbin.
  • the invention is therefore based on the object of specifying a method for winding yarns or tapes supplied at a constant speed in a gradual precision winding, which has the disadvantages of the known methods, but in particular too large differences in the winding speed and their adverse effects on the quality of the yarns and of the coil structure, on simple Way avoids.
  • 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 bobbin (2) is driven at its circumference by means of a drive roller (3) at constant circumferential speed in order to wind up yarn (1) fed at a constant 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 pulse (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 via the supply voltage in the desired sense.
  • 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 be such that integer winding ratios are run through faster than a winding game lasts.
  • the crossing angle is 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. In this case, a change in the wind speed of less than 3% would still have no adverse effects on the quality. In contrast, in a spinning draw frame for high-strength, low-stretch yarns, increasing the wind speed will affect the thread tension. If this is too high, this can be noticeable both as a fluctuation in the elongation in the yarn and as an unfavorable influence on the even package build. 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 at the beginning of the spool. For a good spool build-up, it is essential that the sum of these stroke reversal points is distributed as evenly as possible at the start of the spool. At the same time, however, their order should also be as symmetrical as possible and avoid a temporal focus.
  • 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 is built up in gradual precision 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 signal for switching occurs at a 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%.
