Definitions
- the invention relates to a method for operating a workstation of a cross-wound textile machine according to the preamble of claim 1.
- Textile machines producing cross-wound bobbins which have a multiplicity of similar workstations each having an open-end spinning device for manufacturing a thread and a winding device for producing a cross-wound bobbin, have long been known in the textile machine industry in various embodiments and are described in numerous patents.
- the open-end spinning devices of the work stations are equipped with a sliver-opening device whose opening roller is preferably driven by a machine-tangential belt.
- opening rollers are known, which are acted upon by a single electric motor drive (DE 43 09 947 Al, DE 100 54 697 Al, DE 103 38 842 Al).
- an open-end spinning device can only work if the associated sliver-opening device always supplies the required number of individual fibers to the spinning rotor, which combs the opening roller for this purpose continuously from a master fiber tape.
- Sensor devices are known to be prevented by the fact that the sliver end of a sliver completely enters the sliver-opening device of a job, disadvantageous in these known devices, however, that this usually optical sensor devices are relatively sensitive to the almost inevitable in spinners dust and fluff are.
- the present invention seeks to develop a cost-effective and reliable method with which can be determined in a simple manner, whether in the sliver-opening device of an open-end spinning still original fiber ribbon is fed, or whether the sliver Opening device of the relevant job is already idle.
- the inventive method in which the motor current for the electromotive single drive of the opening roller is monitored and is closed from the measured value of the power consumption of this drive on the presence or absence of a template sliver in the field of opening roller has the advantage that for monitoring the Sliver no sensitive sensors is needed. That is, no sensor, with the risk that it will be dirty during the spinning operation over time and thus ineffective.
- the measured value of the power consumption processed in a control device of the work to fall below a lower threshold for the power consumption of the electric motor drive the opening roller interpreted as a lack of a master fiber ribbon and the job immediately stops.
- shut down jobs are preferably also, as described in claim 5, characterized by the setting of a signal.
- the setting of a signal not only prevents the service unit from being blocked at a workstation that can not be operated, but also immediately signals to the operator of the textile machine that action is required at the relevant workstation.
- This signal is also set at the workstation of a textile machine when the textile machine has self-sufficient workstations, that is, when the workstations "normal" spin breaks on its own, without the help of a service unit fix.
- the work in question is shut down when, after activation of the Faserbandzu GmbHzylinders the power consumption of running at operating speed drive the opening roller does not rise significantly.
- the opening roller idles is significantly lower than the power of a revolving at operating speed drive, the opening roller combs out a feed belt, can from the lack of a significant increase in power consumption of the drive when switching the sliver feed reliable and simply be closed to the absence of a template fiber band.
- the power consumption of a drive whose opening roller has run up to operating speed determined and compared with the power consumption of the drive, which is adjusted when the sliver takes place. It can be seen from the power consumption of the drive when the sliver feed is switched on, whether a sliver of original fiber is drawn into the sliver-opening device and combed out by the opening roller.
- the determination of the instantaneous power consumption of the electromotive drive of the opening roller by measuring the motor current of the drive take place in that at least one corresponding measuring coil, which is preferably connected to the spinning station's own control device, at least one of the phases of the energy supply Drive is positioned.
- a voltage is thereby induced, which is proportional to the current flowing in the relevant phase motor current, and which can be measured directly at the measuring coil.
- the sensor elements described above are inexpensive and insensitive to the hardly permeated in spinners dust-penetrated atmosphere.
- FIG. 1 schematically shows a front view of an open-end rotor spinning machine with a plurality of work stations, each of which has an open-end spinning device with a sliver-opening device, the opening roller of which has an electromotive single drive,
- FIG. 2 shows a side view, partly in section, of an open-end spinning device with a sliver-opening device which has an opening roller which can be acted upon by an electromotive single drive with a circuit arrangement suitable for carrying out the method according to the invention
- FIG. 3 shows a circuit arrangement for measuring the motor current by means of a measuring coil on at least one phase
- FIG. 4 shows a circuit arrangement for measuring the motor current by means of a measuring shunt on at least one phase.
- FIG. 1 schematically shows a front view of an open end

- Supply of jobs 4 are connected to electrical energy.
- Rotor spinning machine 1 that is, the open-end
- Open-end rotor spinning machine 1 Open-end rotor spinning machine 1 arranged.
- the central control unit 5 is in turn with the
- a master fiber tape 15 which is stored in sliver cans 16, which are positioned in series next to each other below the jobs 4, spun into a thread 17, which is then on the winding device 18 to a cross-wound bobbin 19 is wound up.
- FIG. 2 shows a side view of an open-end spinning device 12 of one of the numerous work stations 4 of the open-end rotor spinning machine 1.
- Such open-end spinning devices 12 are known per se and relatively extensively described, for example, in DE 103 38 901 A1.
- Such open-end spinning devices 12 have a single-motor driven spinning rotor 8, the rotor cup 9 rotates during spinning at high speed in a rotor housing 11 under horrbeetzschlagbaren.
- the rotor housing 11 which is closed at the front by a cover element 13 during the spinning operation, is connected via a
- Vacuum channel connected to the spinning machine's own vacuum source 10, which required for spinning vacuum in the
- Rotor housing 11 provides.
- the electromotive single drive 20 of the spinning rotor 8 is connected to the power supply device 21 of the relevant
- the electromagnetic single drive 20 is also connected for this purpose via at least one signal line 22 to a workstation's own control device 6.
- Spinning operation closes is limited to a pivot axis 23 rotatably mounted, so that the stationary spinning rotor 8 at
- a so-called channel plate adapter 24 is also inserted into the cover element 13, interchangeable, to which a thread withdrawal tube 25 adjoins.
- Disintegrating roller housing 26 a generally designated by the reference numeral 30 sliver-opening device.
- This sliver-opening device 30 consists essentially of a single-motor driven dissolving roller 27 and a preferably also via a single drive 35 drivable sliver feed cylinder 34th In Auflensewalzengephinuse 26 also a sliver feed cylinder 34 is rotatably mounted, which can be acted upon by an electric motor 35 by a drive 35, preferably a stepper motor.
- the drive 35 of the Fasebandeinzugszylinders 34 is connected via supply lines 36 to the power supply device 21 of the textile machine 1 and a signal line 37 with the workstation's own control device 6 in connection.
- the opening roller 27 rotatably mounted in the opening roller housing 29 is fixed with its bearing shaft 32 in a rear bearing bracket 28 of the opening cylinder housing 26.
- the opening roller 27 is driven by an electromotive single drive 31, which is preferably designed as an external rotor.
- an electromotive single drive 31 is arranged in the end region of the bearing shaft 32, which has a plurality of galvanically isolated contact tracks.
- the contact tracks are connected via a supply line 38 to the power supply device 21 of the open-end rotor spinning machine 1 and via a signal line 39 to the workstation's own control device 6.
- a measuring device 40 is turned on, with which the respective motor current of the opening roller drive 31 can be detected.
- the measuring device 40 may, for example, as shown in Figure 3, have a measuring coil 41 which encloses at least one of the phases of the primary circuit 45 and a Secondary circuit 43 forms or, as shown in Figure 4, be designed as a measuring shunt 44.
- a voltage in the secondary circuit 43 is induced by the motor current in the primary circuit 45 via the measuring coil 41, which is measured.
- the measured secondary voltage U sec is proportional to the motor current in the primary circuit 45 that depends on the respective power consumption of the opening roller drive 31.
- the measuring device 40 with measuring shunt 44 shown in FIG. 4 works in a similar way in principle.
- the measured voltage U S hunt is proportional to that of the respective power consumption of the
- Another method is the measurement of the motor current by means of a driver IC present in the motor circuit of the opening roller drive. In this case, no additional sensor system is required.
