Definitions
- the present invention relates to a method for operating an open-end spinning device according to the preamble of claim 1.
- the piecing is usually carried out at the individual spinning stations of the open-end rotor spinning machines by a spinning along the spinning machine piecing, the so-called piecing.
- the opposite of the operating speed of the opening roller higher Anspinnnaviere causes a higher fiber throughput, whereby after the structure of the fiber ring during the piecing process in the spinning rotor such a quantity of fiber ready for piecing that after processing of the fiber ring no delay-induced fiber deficiency arises, which causes a thin spot.
- the higher piecing speed of the opening roller moreover achieves a more effective combing out of the fibers, which additionally leads to an improvement in the piecing behavior.
- the Anspinnnaviere the opening roller should be achieved before the beginning of piecing.
- the reproducibility of the fiber feed required for the quality of the piecing is achieved. Since the combing out of the fibers always takes place at the same piecing speed of the opening roller, the spinning rotor is always supplied with the same amount of fiber during piecing.
- the piecing speed of the opening roller can be maintained during the complete processing of the draw-in addition.
- the increased fiber throughput is kept constant even beyond the completion of the actual piecing process in order to avoid, as desired, a thin spot following the piecer.
- the piecing speed becomes the opening roller reduced to the normal spinning operation adapted operating speed. This serves to ensure the yarn uniformity of the yarn to be spun.
- the open-end spinning device can be operated both for the piecing process and for the spinning operation with an opening roller speed optimally adapted to these processes.
- the speed control of the opening roller during the piecing process and the process of Einzugsaufadd ist of other, these operations affecting parameters independently by a control device is achieved by the use of single-motor drives, for example for the spinning rotor and the opening roller, which are each connected via signal lines to the control device and are independently controlled by them.
- FIG. 1 shows an open-end rotor spinning device with single motor drives at least for spinning rotor, opening roller and a control device for these drives;
- Figure 2 shows the profile of a piecer at a piecing speed of the opening roller of 5,500 revolutions per minute.
- FIG. 3 shows the profile of a piecing at a piecing speed of the opening roller of 10,000 revolutions per minute.
- the illustration in FIG. 1 shows an open-end spinning device 1 of an open-end rotor spinning machine, which are arranged in the region of the spinning stations of such textile machines.
- Such open-end spinning devices 1 are known in principle and described in detail in DE 196 50 597 A1, for example.
- the open-end spinning device 1 comprises a spinning rotor 2 with rotor cup 4, which during the spinning operation at high speed in a pressurizable with a vacuum
- Spinning rotor housing 5 rotates.
- the spinning rotor 2 is defined by a controllable electric motor single drive 3, which is connected via electrical lines 20 to the power supply 23 of the textile machine concerned, driven.
- the electromotive single drive 3 is connected for this purpose via at least one signal line 22 to a control device 21.
- the cover element 8 which closes the rotor housing 5 during the spinning operation, is mounted so as to be limitedly rotatable about a pivot axis 16, so that the stationary spinning rotor 4 is accessible as required.
- a so-called channel plate adapter 9 is inserted, to which a thread withdrawal tube 10 is connected.
- the cover element 8 has an opening roller housing 11, in which an opening roller 12 rotated, which is fixed with its bearing shaft 17 in a rear bearing bracket 14 of the opening roller housing 11.
- the opening roller 12 is driven by an electromotive single drive 24, which is designed as an external rotor, and has a contact track device 18 for easily releasable coupling to the power supply 23 of the open-end rotor spinning machine in the end region of its bearing shaft 17.
- the electromotive single drive 24 is also connected via a signal line to the control device 21 and controlled via this.
- In Auflensewalzengeophen 11 also a sliver feed cylinder 13 is rotatably mounted, which can be acted upon by a motor 15, preferably a stepper motor, by an electric motor. Also, the drive 15 is connected via an electric line 26 to the power supply 23 of the textile machine and a signal line 25 to the controller 21.
- the spinning device 1 After the occurrence of an interruption of the spinning process by detecting the absence of a thread by means of a fader monitoring device, not shown, the spinning device 1 is initially set still. Subsequently, a piecing process for thread connection is initiated.
- the piecing process begins with fiber bargaining to provide the same conditions for the piecing process, regardless of how long the shutdown of the spinning device 1 lasts.
- the spinning rotor 2 Following the Faserbartegalmaschine is first the spinning rotor 2, which has a speed of about 120,000 min "1 or more in the spinning operation, so high that the spinning rotor 2 has a required for the successful implementation of the piecing operation minimum speed, in particular the execution and operating speed of the respective spinning rotor 2 is dependent.
- the control of the single-motor drive 3 of the spinning rotor 2 takes place for this purpose by the control device 21st
- the controller 23 controls the controller 23 such that it has an independent of the minimum speed of the spinning rotor 2 Anspinnnaviere, which is above the operating speed.
- the piecing speed is preferably between 10% and 40% above the operating speed of the opening roller 11 in the spinning operation.
- the piecing speed is reached before the start of the piecing process. With the beginning of piecing the sliver is combed out more intensively by the rotating with the higher piecing speed opening roller 12 and the
- the prepared for piecing yarn end is introduced through the exhaust pipe 10 in the rotating spinning rotor 2, where it strikes the fiber ring previously constructed in the spinning rotor 2.
- the thread end breaks up the fiber ring and connects to the fibers that deposit at the thread end, creating the piecing.
- the subsequent addition of the thread to the fiber ring process of the intake charge addition serves to delay the occurring fiber supply between the Pre-feed for piecing and re-starting the fiber supply to compensate.
- a delay of the fiber feed causes the yarn during the startup of the spinning rotor 2 has irregularities in the form of a thin spot, which occur immediately after the piecer and affect the quality of the thread lasting. Over the period for performing the piecing and the draw-in addition, the rotational speed of the spinning rotor 2 increases smoothly until the operating speed is reached.
- FIG. 2 shows a diagram of a thread profile in the piecing region, which results at a piecing speed of the opening roller 12 of approximately 5,500 min -1 .
- a thin spot forms after the piecing Deviation from the thread profile is compensated for later in the course of the thread length to the desired thread profile when the open-end spinning device 1 has reached its operating state after the piecing process, that is, if, among other things, the opening roller 12 and the spinning rotor 2 are driven at their respective operating speeds ,
- Fig. 3 shows a thread profile in the piecing area, which results at a piecing speed of the opening roller 12 of about 10,000 min -1 .
- a thread profile is formed, which almost corresponds to the thread profile which is achieved during the spinning process This is due to the increase in the amount of fiber provided, which is achieved by the increased piecing speed of the opening roller 12.
- the piecing speed of the opening roller 12 is only after the completion of the intake charge addition to the for the spinning operation required optimum operating speed of the opening roller 12 is reduced.
