Definitions

  • the invention relates to a device for guiding, treating or conveying at least one thread according to the preamble of claim 1.
  • the delivery roller and the auxiliary role are each driven by an electric motor designed as a synchronous motor.
  • the electric motors are controlled by a control unit by a target frequency to drive each of the delivery and the Beilaufrolle with the same peripheral speed.
  • the design of the drives is based on the fact that in order to maintain as constant a thread speed as possible, the peripheral speed of the delivery roller and the peripheral speed of the auxiliary roller must be kept constant. In practice, however, even slight inaccuracies in the mantle of the delivery roll or in the mantle of the loose roll lead to deviations in the jacket diameters, which has an immediate effect on a change in the peripheral speeds. This effect causes the thread at the circumference of the axler be either braked or fed with a flow. However, such interactions lead to a troubled threadline, which has a negative effect especially in the leadership of several parallel running parallel threads.
  • the invention is therefore based on the object, a device of the type mentioned in such a way that the thread can be performed at the periphery of the supply roll and on the circumference of the Beilaufrolle at a substantially constant speed.
  • the electric motor of the by-pass roller is designed as an asynchronous motor which is controlled by a nominal frequency and which has a motor slip.
  • the invention has the particular advantage that the fan-out roller can be operated at a speed which is based on the actual peripheral speed of the delivery roller.
  • the electric motor of the delivery roller is also designed as an asynchronous motor, which, however, has a control feedback.
  • the sensor is supplied with a sensor which serves to measure an actual frequency. Via a signal line, the actual frequency is supplied to the control unit, in which a correction of the desired frequency takes place. Since both the asynchronous motor of the delivery roller and the asynchronous motor of the by-pass roller are controlled by the reference frequency of the control unit, the change in the nominal frequency is also abandoned analogously to the asynchronous motor of the supplementary role.
  • This has the particular advantage that, when loaded, the asynchronous motors can be operated with a tendency to have the same field orientation, so that the flywheel has a supporting effect on the delivery roller in order to apply a total traction.
  • the asynchronous motor of the by-pass roller is designed to be as electrically soft as possible, ie. H. the asynchronous motor of the auxiliary role has a relatively large engine slippage.
  • the asynchronous motor of the delivery roller is executed with the lowest possible engine slip.
  • the supply roll and the auxiliary roll can have a substantially equal coat diameter.
  • the by-pass roller is formed with a much smaller sheath diameter.
  • the asynchronous motor of the Beilaufrolle is designed with a smaller number of pole pairs to convert the target frequency in a corresponding peripheral speed.
  • the delivery roller and / or the accompanying roller have at least one diameter step.
  • This embodiment is particularly advantageous, for example, to carry out a swirling of the thread within a preferably last looping of the thread between the delivery roller and the loose roll.
  • the supply roll and / or the auxiliary roll could have at least one conical jacket region.
  • the supply roll is preferably made with a heating means, so that the jacket of the supply roll has a temperature required for the treatment of the yarn.
  • the setting has proved successful, in which the peripheral speed of the The idler pulley of the asynchronous motor is 0.1 - 10% above the peripheral speed of the delivery roller.
  • the peripheral speed of the The idler pulley of the asynchronous motor is 0.1 - 10% above the peripheral speed of the delivery roller.
  • Fig. 1 schematically a view of a first embodiment of the device according to the invention is shown.
  • the device has a delivery roller 2 and an enclosed at a distance from the delivery roller 2 arranged Beilaufrolle 3.
  • the delivery roller 2 is rotatably mounted projecting on a support 4.1 and connected by a drive shaft 5 with an electric motor 7.
  • the electric motor 7 of the delivery roller 2 is designed as an asynchronous motor.
  • the asynchronous motor 7 is coupled to the control unit 10 via the control line 9.1.
  • a sensor 11 for detecting an actual frequency of the asynchronous motor 7 is provided at the asynchronous motor 7 is provided.
  • the sensor 11 is connected by the signal line 12 to the controller 10.
  • the Beilaufrolle 3 is cantilevered on the support 4.2 and is driven by the electric motor 8 via the drive shaft 6.
  • the electric motor 8 of the auxiliary role 3 is designed as an asynchronous motor.
  • the asynchronous motor 8 is connected via the control line 9.2 with the control unit 10.
  • Fig. 1 If the device according to the invention is shown in an operating state. In this case, a thread 1 is guided in several wraps on the supply roller 2 and the Beilaufrolle 3. In this embodiment, only one thread is shown. However, the device according to the invention is preferably used to guide a plurality of parallel threads 1. For example, to draw the yarn from a spinneret or to draw in a draw zone, the supply roll 2 and the follower roll 3 are driven at substantially the same peripheral speed. For this purpose, the asynchronous motor 7 of the delivery roller 2 is controlled by the control unit 10 with a predetermined desired frequency.
  • the actual frequency is detected by the sensor 11 with the asynchronous motor 7 of the delivery roller and fed to the control unit 10 through the signal line 12.
  • the delivery roller 2 is driven at a predetermined target speed, which is independent of the engine slip of the induction motor 7 ..
  • the drive of the Beilaufrolle 3 by the induction motor 8 is carried out with identical nominal frequency, which is given by the control unit 10 via the control line 9.2 the induction motor 8.
  • the asynchronous motor 8 has compared to the asynchronous motor 7 of the delivery roller a smaller number of pole pairs, which is selected according to the diameter ratios of the sheath diameter of the delivery roller 2 and the sheath diameter of the Beilaufrolle 3.
  • the asynchronous motor 8 of the fan-out roller 3 is particularly electrically soft and thus has a relatively high engine slippage.
  • the actual peripheral speed of the flywheel 3 adapts to the respective load state, so that no undesired interactions are produced on the thread 1 between the delivery roller 2 and the slip roller 3.
  • the uncontrolled peripheral speed of the by-pass roller 3 thus substantially equals the regulated peripheral speed of the delivery roller 2.
  • Fig. 2 is another example of such a device shown schematically.
  • the example in Fig. 2 is substantially identical to the previous embodiment according to Fig. 1 , so that reference is made to the preceding description and only the differences are shown below.
  • the components with the same function have been given identical reference numerals.
  • asynchronous motor 7 of the supply roller 2 and the asynchronous motor 8 of the fly-by roller 3 are formed identically, since the supply roller 2 and the Beilaufrolle 3 have a same size shell diameter.
  • the control of the asynchronous motor 7 for driving the supply roller 2 and the control of the asynchronous motor 8 of the auxiliary pulley 3 is identical to the previous embodiment.
  • Each of the asynchronous motors 7 and 8 are controlled with a set by the control unit 10 target frequency, wherein the target frequency in the control unit 10 according to the actual frequency of the induction motor 7 of the delivery roller 2 is determined and specified.
  • the supply roller 2 in the example after Fig. 2 executed with a diameter level 13.
  • the axler 3 does not contain a diameter step.
  • a differential speed which leads to a thread tension relief in the thread 1.
  • This can be used, for example, advantageously to swirl the thread 1 between the delivery roller 2 and the Beilaufrolle 3.
  • Fig. 2 a Verwirbelungsdüse 14 shown in dashed lines.
