Definitions

  • the object of this invention is in the field of thread rewind.
  • the present invention relates to a winding unit for winding a spun thread according to the preamble of independent claim 1 and to a correspondingly equipped spinning machine.
  • Such devices are known in the textile industry.
  • winding or winding of a thread is known to be used with winding machines that work according to various winding laws and thereby either a wild
  • Winding or a precision winding or a step precision winding produce are in particular the so-called turn ratio (defined as the number of turns of the coil per double stroke), the pitch angle of the thread laying, which corresponds to half the crossing angle, and the speed.
  • Winding is understood to mean windings whose winding ratio continuously decreases with increasing winding diameter, the angle of intersection remaining constant.
  • a wild winding is created by keeping the thread transfer speed and the peripheral speed of the bobbin constant.
  • the image zones represent a very serious disadvantage.
  • precision winding the turns ratio remains constant throughout the winding process. However, the crossing angle changes and becomes smaller with increasing coil diameter.
  • a precision wound coil does not have any image zones at optimally selected number of turns, which results in very good pull-off properties.
  • Advantages of a precision winding include: No windings of the windings, uniform course of yarn tension during removal of the spool, high density and uniform density distribution of the yarn on the spool, better flow through of the dyes in the further processing, and higher running times without Failure during unwinding of the bobbin during subsequent weaving and knitting of the yarn.
  • the dimensional stability in the axial direction decreases because of the changing over the coil assembly pitch angle of the thread laying in the precision winding, but is not a disadvantage in the outer layers.
  • the step precision winding represents a combination of the two winding laws, wild winding and precision winding.
  • the combination of the advantages of these two winding laws is achieved in that in a winder with a by a motor drive driven driveline and with a driven by a transmission with variable ratio thread laying to produce a precision winding the drive roller driven by a drive with a fixed ratio and the gear for the Fadeverlegung is adjusted by a computer controlled actuator, wo ⁇ at each a speed sensor for the measurement of the speed of the cross-wound bobbin and the Fa ⁇ denvertechnisch connected to the computer.
  • the turns ratio is predetermined and after the decrease of the crossing angle by a predetermined amount, the computer switches over to a predetermined lower number of turns.
  • the result is concentric rings with recuperzisions ⁇ winding, wherein from ring to ring with increasing coil diameter, the Win ⁇ tion ratio abruptly discrete predetermined value assumes that the crossing angle varies only within narrow limits.
  • the approximately constant crossing angle corresponds to a wild winding and the retention of the turns ratio in diameter steps of a precision winding.
  • Said EP 950 627 describes a method and a device for winding up a yarn supplied at a constant speed from a spinning machine by means of a thread-changing device to a coil with precision or step precision winding.
  • a disadvantage of said device is that it requires a relatively complicated control and expensive device.
  • the present invention is therefore based on the object to provide a winding unit, which has the simplest possible drive and with which Rezisions ⁇ coils can be produced.
  • the inventive device By using the inventive device it is achieved that one can produce a precision coil with ein ⁇ fold means. Thanks to the invention, it is now possible, despite the use of relatively simple Fritationswalzenantriebes to produce a coil with the best yarn flow properties in further processing.
  • three different winding types can be produced with the same device: a) wild winding (random winding), b) precision winding, and c) step precision winding.
  • the winding unit according to the invention thus provides the operator of the machine with maximum flexibility in the choice of the type of winding.
  • the traversing device is configured as a flight calibration (see figures). This ensures a highly dynamic thread laying, which enables very high laying speeds and yet remains easy to handle. Thanks to the rotating blades, a smooth low-energy traversing device is obtained which, moreover, does not require any oscillating masses with enormously high accelerations in the reversal areas of the stroke (no high load on the drive system and the traversing device).
  • FIG. 1 Drive transmission according to the invention via the coil
  • FIG. 3 Spinning station of a spinning machine with winding unit according to the invention 1 shows a possible embodiment of the inventive Spulein ⁇ unit.
  • the winding unit 1 shown serves for winding a spun yarn 2 onto the spool 3 or onto the spool sleeve 4. Since the spool unit according to the invention is preferably intended for installation in spinning machines, the thread 2 shown in FIG. 1 is usually also made from a spinning box (not shown). As can be seen in the figure, the entire winding unit 1 is driven by the motor M.
  • the motor M is a component of the friction roller drive 5.
  • the mode of operation of the friction roller drive 5 is generally known:
  • the motor M drives the friction roller 6 and thus the coil 3 or the coil sleeve 4.
  • New to the winding unit 1 is now the manner How the traversing device 7 is driven:
  • the transmission of the drive energy for the traversing device 7 is ensured by a drive transmission 8 from the coil 3 or from the coil sleeve 4.
  • the drive transmission 8 according to the invention ensures slip-free transmission of the drive energy to the traversing device 7.
  • the drive transmission 8 is preferably configured with positive or frictional engagement, for B. by drive belt 12 with corresponding teeth or by the ribs 11 of the bobbin 4.
  • the drive transmission shown in Figure 1 8 is shown only schematically by drive belt 12 and the gears 22.
  • the drive transmission 8 According to the invention, however, these have a slip-free transmission of the drive energy, so that the Windungs ⁇ ratio (ie the number of coil revolutions per double stroke of the thread) remains constant, thereby allowing a precision winding on the coil.
  • the drive transmission 8 according to the invention thus characterizes the winding unit 1 as a precision winder.
  • the bobbin 4 For the transmission of the drive energy from the coil 3 to the traversing device 7, the bobbin 4, for example, have special constructive measures. This can, for example, as shown in the figure, have ribs 11 at one or more points.
  • wing traversing is used for the traversing device 7 (see wing 14). The two wings rotate in opposite directions. The corresponding drive system (plants) is not shown.
  • the figure 1 the drive transmission 8 according to the invention. According to the invention, however, these have a slip-free transmission of the drive energy, so that the Windungs ⁇ ratio (ie the number of coil revolutions per double stroke of the thread) remains constant, thereby
  • FIG. 2 shows a further exemplary embodiment of the winding unit 1 according to the invention, in which the drive energy is not transmitted to the drive transmission 8 via the bobbin tube 4 but via the coil plate 20.
  • the coil plate 20 is madestat ⁇ tet with a special surface 10 for energy transfer.
  • the coil plate 20 has in this further embodiment of the invention as the bobbin tube of Figure 1 ribs 11, which transmit the drive energy.
  • ribs 11 which transmit the drive energy.
  • the drive transmission 8 from the coil 3 can decouple and that an additional independent drive 13 is provided for the traversing device.
  • the same winding unit 1 can be operated both as a precision winder and as a winder.
  • the additional independent drive 13 is preferably connected to the controller 9 of the friction roller drive, which thus also assumes the control of the drive 13.
  • This preferred embodiment of the invention has the advantage that one can produce different winding types with the same device. In addition to the precision winding, it is thus possible to produce the aforementioned wild winding (feed winding) as well as step precision windings.
  • the controller 9 of the friction roller drive is preferably connected in all embodiments of the invention with a device for measuring the spinning tension 19.
  • the rotational speed of the friction roller 6 is preferably controlled by the spinning tension.
