Definitions

  • the invention relates to a device for guiding, treating or conveying at least one thread according to the preamble of claim 1.
  • devices are used for guiding and conveying a thread, for example in a spinning process, which consist of a delivery roller and an idler roller assigned to the delivery route, in order to enable the thread to be wrapped multiple times.
  • the delivery roller is driven, the feed roller can be designed with or without a drive, as described for example in EP 1 001 521 A2.
  • the delivery roller and the idler roller are each driven by an electric motor designed as a synchronous motor.
  • the electric motors are controlled by a control unit by a set frequency in order to drive the delivery roller and the idler roller at the same peripheral speed.
  • the design of the drives is based on the fact that the circumferential speed of the delivery roll and the circumferential speed of the idler roll must be kept constant in order to maintain a thread speed that is as constant as possible. In practice, however, even slight inaccuracies in the jacket of the delivery roll or in the jacket of the idler roll lead to deviations in the jacket diameter, which has a direct effect on a change in the peripheral speeds.
  • the invention is therefore based on the object of designing a device of the type mentioned at the outset in such a way that the thread can be guided at an essentially constant speed on the circumference of the delivery roller and on the circumference of the feed roller.
  • the electric motor of the idler roller is designed as an asynchronous motor which is controlled by a target frequency and which has motor slip.
  • the invention has the particular advantage that the idler 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 feedback control system.
  • a sensor is attached to the asynchronous motor of the delivery roll, which serves to measure an actual frequency.
  • the actual frequency is fed to the control unit via a signal line, in which the target frequency is corrected. Since both the asynchronous motor of the delivery route and the asynchronous motor of the idler roller are controlled by the target frequency of the control unit, the change in the target frequency is also abandoned analogously to the asynchronous motor of the idler roller.
  • the asynchronous motors can tend to be operated with the same field orientation under load, so that the idler roller acts as a support to the delivery roller in order to apply a total tractive force.
  • the asynchronous motor of the idler roller is designed to be as electrically soft as possible, ie the asynchronous motor of the idler roller has a relatively large motor slip.
  • the asynchronous motor of the delivery roll is designed with as little motor slip as possible.
  • the delivery roller and the idler roller can have a jacket diameter of essentially the same size.
  • the filler roller is preferably designed with a substantially smaller jacket diameter.
  • the asynchronous motor of the idler roller is designed with a smaller number of pole pairs in order to convert the target frequency into a corresponding peripheral speed.
  • the delivery roller and / or the idler roller have at least one diameter step.
  • This design is particularly advantageous in order, for example, to swirl the thread within a preferably last loop of the thread between the delivery roller and the idler roller.
  • the delivery roller and / or the idler roller could have at least one conical jacket area.
  • the delivery roll is preferably carried out with a heating medium, so that the jacket of the delivery roll has a temperature required for treating the thread.
  • the setting has proven itself in which the peripheral speed of the idler roller when the asynchronous motor is idling is 0.1-10% above the peripheral speed of the delivery roller.
  • a braking effect of the threads on the idler roller can advantageously be used.
  • Fig. 1 shows schematically a first embodiment of the device according to the invention
  • Fig. 2 schematically shows another embodiment of the device according to the invention
  • the device has a delivery roller 2 and an idler roller 3 arranged at a distance from the delivery roller 2.
  • the delivery roller 2 is cantilevered on a support 4.1 and is connected by a drive shaft 5 to 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 is provided on the asynchronous motor 7 of the delivery roller 2 Detection of an actual frequency of the asynchronous motor 7 is provided.
  • the sensor 11 is connected to the control unit 10 by the signal line 12.
  • the idler roller 3 is cantilevered on the carrier 4.2 and is driven by the electric motor 8 via the drive shaft 6.
  • the electric motor 8 of the idler roller 3 is designed as an asynchronous motor.
  • the asynchronous motor 8 is connected to the control unit 10 via the control line 9.2.
  • the device according to the invention in an operating state.
  • a thread 1 is guided in several loops over the delivery roller 2 and the idler roller 3.
  • the device according to the invention is preferably used to guide several threads 1 running in parallel.
  • the delivery roller 2 and the idler roller 3 are driven at essentially the same peripheral speed.
  • the asynchronous motor 7 of the delivery roller 2 is controlled by the control device 10 with a predetermined target 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. It is thus achieved that the delivery roller 2 is driven at a predetermined target speed which is independent of the motor slip of the asynchronous motor 7.
  • the asynchronous motor 8 drives the idler roller 3 with an identical setpoint frequency, which is given to the asynchronous motor 8 by the control device 10 via the control line 9.2.
  • the asynchronous motor 8 has a smaller number of pole pairs than the asynchronous motor 7 of the delivery roller, which is selected in accordance with the diameter ratios of the jacket diameter of the delivery roller 2 and the jacket diameter of the idler roller 3.
  • the asynchronous motor 8 of the idler roller 3 is particularly electrically soft and thus has a relatively high motor slip.
  • the uncontrolled peripheral speed of the feed roller 3 thus essentially adjusts to the regulated peripheral speed of the delivery roller 2.
  • FIG. 2 A further exemplary embodiment of the device according to the invention is shown schematically in FIG.
  • the exemplary embodiment in FIG. 2 is essentially identical to the previous exemplary embodiment according to FIG. 1, so that reference is made to the preceding description at this point and only the differences are shown below.
  • the components with the same function have been given identical reference symbols.
  • the asynchronous motor 7 of the delivery roller 2 and the asynchronous motor 8 of the idler roller 3 are of identical design, since the delivery roller 2 and the idler roller 3 have a jacket diameter of the same size.
  • the regulation of the asynchronous motor 7 for driving the delivery roller 2 and the control of the asynchronous motor 8 of the idler roller 3 is identical to the previous exemplary embodiment.
  • Each of the asynchronous motors 7 and 8 are controlled with a target frequency given by the control unit 10, the target frequency in the control unit 10 being determined and predetermined in accordance with the actual frequency of the asynchronous motor 7 of the delivery roller 2.
  • the delivery roller 2 in the exemplary embodiment according to FIG. 2 is designed with a diameter step 13.
  • the side roller 3 contains no diameter step.
  • Differential speed which leads to a relief of thread tension in thread 1.
  • This can be used advantageously, for example, to swirl the thread 1 between the delivery roller 2 and the idler roller 3.
  • a swirling nozzle 14 is shown in broken lines in FIG. 2.
  • the exemplary embodiments shown in FIGS. 1 and 2 can also advantageously be designed such that the delivery roller 2 is driven by a synchronous motor.
  • the synchronous motor of the delivery roller 2 and the asynchronous motor of the idler roller 3 are controlled by the control unit 10 with an identical target frequency.
  • the asynchronous portion of the motor ensures an advantageous start-up after switching on until the target frequency is reached.
  • the synchronous component ensures that the delivery roller is driven at a frequency that does not deviate from the target frequency. In this way, multiple delivery roles can be controlled via a common converter.
