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 yarn according to the preamble of independent claim 1 and to a correspondingly equipped spinning machine.
  • Such devices are known in the textile industry.
  • the winding or winding of a thread is known to be used with winding machines which operate according to various winding laws and thereby produce either a wild winding or a precision winding or a step precision winding.
  • the relevant winding parameters 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 corresponding to half the crossing angle and the speed determined by the turn ratio.
  • Wild winding is understood to mean windings whose turns ratio decreases continuously as the diameter of the coil increases, the crossing angle remaining constant.
  • a wild winding is created by the fact that the thread laying speed and the peripheral speed of the coil remains constant. These conditions can be realized with a relatively simple Fritationswalzenantrieb.
  • the constant crossing angle over the entire coil diameter has a good dimensional stability and transportability of the coil thus produced result. Disadvantages arise from unfavorable number of turns, which become noticeable during the coil construction with certain coil diameters as so-called images or image zones. In these zones, thread is placed next to thread or even thread on thread directly above each other. The consequence of these image zones is uneven yarn development, which can later lead to yarn tension peaks during unwinding or even yarn breaks. Since the following processing processes work almost consistently at high to very high take-off speeds, the image zones represent a very serious disadvantage.
  • 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 knows no image zones with optimally selected number of turns, which has very good pull-off properties.
  • the advantages of a precision winding include: No entanglements of the windings, uniform yarn tension when pulling off the bobbin, high density and even density distribution of the thread on the bobbin, better flow of the dyes in the further processing, as well as longer running times without failures during unwinding of the bobbin during subsequent weaving and knitting the yarn. In contrast, the dimensional stability is not so good because of the changing over the coil structure pitch angle of the thread laying in the precision winding.
  • 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 driven by a transmission with variable transmission thread laying to produce a precision winding the drive roller driven by a drive with a fixed ratio and the transmission for the Fadeverlegung is adjusted by a computer-controlled actuator, each having a speed sensor for measuring the Speed of the cheese and the thread laying is connected to the computer.
  • the turns ratio is specified and after the decrease of the crossing angle by a predetermined amount, the computer switches to a predetermined lower number of turns.
  • the result is concentric rings with precision winding, wherein from ring to ring with increasing coil diameter, the turns 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 an apparatus for winding a yarn delivered at a constant speed from a spinning machine by means of a threading device into a precision or step precision winding package.
  • 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 precision coils can be produced.
  • 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 gives the operator of the machine maximum flexibility in the choice of the type of winding.
  • the traversing device is designed as wellgelchang réelle (see figures). This ensures a highly dynamic thread laying, which allows very high laying speeds and yet easy to handle. Thanks to the rotating blades you get a smooth low-energy traversing device, which also requires no 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 shows a possible embodiment of the winding unit according to the invention.
  • 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 part of the Fritationswalzenantriebes 5.
  • the operation of the Fritechnischswalzenantriebes 5 is well known: the motor M drives the friction roller 6 and thus the coil 3 and the bobbin 4.
  • the transmission of the drive energy for the traversing device 7 is ensured by means of a drive transmission 8 from the spool 3 or from the spool sleeve 4.
  • the inventive drive transmission 8 ensures a slip-free transmission of the drive energy to the traversing device 7.
  • the drive transmission 8 is preferably designed form or frictionally, z. 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. Numerous embodiments are conceivable for the drive transmission 8 according to the invention.
  • the drive transmission 8 thus characterizes the winding unit 1 as a precision winder.
  • 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 the two wings 14).
  • 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 equipped 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 groove or rib-like elements and a frictional transmission would be conceivable.
  • i. 2 shows a further variant of the invention idea:
  • 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 takes over 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 speed of the friction roller 6 is preferably controlled by the spinning tension.
  • FIG. 3 shows a spinning station 16 of a spinning machine 15, which is equipped with the winding unit 1 according to the invention.
  • the winding unit 1 is modular, d. H. it can be installed as a unit and removed or replaced.
  • the spinning module 18 shown is preferably also modular and interchangeable.
  • the invention can be used for various spinning processes and spinning machines.
  • a yarn 2 is produced by an air-spinning method, a rotor-spinning method (open-end spinning method), a friction spinning method, or a falling-jet spinning method (two-nozzle spinning).
