Definitions

  • the invention relates to a method for operating a Open-end spinning machine according to the preamble of claim 1 or a device for performing the Procedure (claim 3).
  • the axes are the Support roller pairs usually somewhat with respect to the rotor axis arranged so that the rotor shaft during the Operation is acted upon by an axial force component.
  • This axial force component holds the rotor shaft securely System on a mechanical shaft arranged on the rotor shaft end Thrust bearing.
  • the restricted arrangement of the Support disc pairs also leads to increased friction in the Area support discs / rotor shaft with the result that it too heating of the treads of the support disks. This frictional heat does not only cover the Support discs heavily loaded; to overcome this friction additional energy is also necessary.
  • the post-published DE 197 29 191.0 discloses a rotor bearing arrangement that avoids the disadvantages described above.
  • the spinning rotor with its rotor shaft is also mounted in the bearing gusset of a support disk bearing, but the axes of the two pairs of support disks are not set in a parallel manner, but are arranged parallel to the rotor shaft.
  • the spinning rotor is axially positioned in the bearing gusset of the support disk bearing via a magnetic bearing arranged on the rotor shaft end, which has radially arranged magnetic bearing components.
  • the special design of this magnetic bearing ensures that the spinning rotor remains securely positioned even at speeds> 100,000 min -1 .
  • the support disc bearing according to DE 197 29 191.0 has undeniable advantages due to its lower energy requirement and its longer service life compared to support disc bearings with set support disc pairs and mechanical axial bearings, it can be used when using these support disc bearings, particularly in spinning mills, in which both open-end spinning devices with mechanical axial bearings and OE spinning devices with magnetic rotor positioning are running, problems arise.
  • Such a spinning rotor installed in a wrong spinning device and thus not fixed in the axial direction also represents an accident risk, not least because of its high operating speed.
  • the The invention is therefore based on the object of a method or to develop a device that the one safe operation of open-end spinning devices with Axial thrust-free support disc bearing guaranteed.
  • this object is achieved by a method as described in claim 1, or by a device according to claim 3.
  • the method according to the invention ensures that only suitably designed spinning rotors can be operated in an open-end spinning device which has an axial thrust-free support disk bearing and is designed for magnetic positioning of the spinning rotor. This means that the method according to the invention reliably prevents a spinning rotor which is designed for an open-end spinning device with set pairs of support disks and mechanical axial bearings or which uses a spinning rotor of the rotating bearing component which does not meet the requirements, from being inadvertently used in such spinning devices.
  • an information carrier is used as the identification mark, which can contain a large number of data, for example the type, size, year of manufacture etc. of the spinning rotor.
  • These data that can be detected by the sensor device of the operating unit are compared and evaluated in the control unit of the operating unit with predetermined data stored in an associated storage unit.
  • the comparison of the data not only detects spinning rotors which are questionable in terms of safety technology, such a comparison can also be used to ensure, for example in connection with a batch change, that the spinning rotors that are correct for the respective yarn batch are always used.
  • a spinning rotor can, if appropriate, be immediately recognized as a spinning means that is questionable in terms of safety or incorrect in terms of spinning technology, which, as already mentioned above, leads to an instantaneous shutdown of the spinning station in question.
  • the spinning rotor has preferably in the area of his spinning cup, via a Identification mark that clearly identifies it as magnetic positionable, constructive exactly on the stationary Magnetic bearing component identifies coordinated spinning rotor.
  • This identification mark is made by a Sensor device on the control unit, for example on The cleaning head of the control unit is arranged (Claim 4), detected and decrypted in the associated control device. That is, in the control device of the control unit a comparison of those stored in a storage device Spinning rotor data with the data of the identification mark performed. Only if this data matches does one find Piecing attempt instead. Unidentifiable, missing or incorrect data automatically leads to an immediate one Stop the spinning station in question.
  • Identification device preferably an electronic one Information carrier is used.
  • the electronic Information carriers can contain a large amount of data, for example about the type of spinning rotor, its size, its coating, its year of construction, etc.
  • the electronic information carrier is designed as a so-called transponder.
  • a transponder is a commercially available, per se passive electronic chip, which, if necessary, is provided via a transmitting and receiving device arranged on the operating unit armed "and then read.
  • An alternative embodiment of an information carrier represents a barcode (Claim 7). In this case it is Sensor device on the control unit designed as a scanner.
  • an identification mark on the spinning rotor which can be detected inductively by the sensor device.
  • the type of information carrier arranged on the spinning rotor it is ensured in any case that a wrong spinning rotor, that is to say a spinning rotor which could lead to the spinning machine or operating personnel being driven, is immediately recognized by the sensor device, with the result that the relevant one Spinning device is stopped.
  • Figure 1 is a side view of a job 2 Open-ended rotor spinning machine identified overall by the reference number 1 shown.
  • These work stations 2 have an open-end spinning device 3 and a winding device 4.
  • the Cross-wound bobbin 8 is in one in the winding device 4
  • Coil frame 9 is stored and is during the coil trip a friction roller 11 driven.
  • the finished cross-wound bobbins 8 are transported away via a machine-long cross-coil transport device 12.
  • the jobs 2 of the open-end rotor spinning machine 1 supplied by an automatically operating control unit 10, which is supported with its undercarriage 17 on rails 14, 14 '.
  • the rails 14, 14 ' preferably run in the superstructure of the Rotor spinning machine 1.
  • the control unit 10 has, as by numerous references known and therefore not closer shown, a variety of handling devices for Spin on or to change the package on.
  • such a control unit 10 has one Unlocking lever 13, with the open-end spinning device if necessary 3 can be opened and closed, as well via a cleaning head 16 for cleaning the spinning rotors 15.
  • the spinning rotors are cleaned both preventively as well as after a thread break.
  • Both the release lever 13 and the one Drive 19 in the direction of the spinning housing 20 of the OE spinning device 3 extendable cleaning head 16 are in themselves known standard components of such control units 10.
  • the control unit 10 is also with its own Control device 18 equipped, for example, via a Machine bus, to a central control unit, not shown the open-end rotor spinning machine 1 is connected.
  • Figure 2 shows a situation in which the Operating unit 10 at a work station 2 of the open-end spinning machine engaged and with its unlocking lever 13 the spinning device 3 has opened. That is, that Cover housing 21 of the OE spinning device 3 is one Swivel axis 22 folded forward.
  • the spinning rotor 15 which rotates at high speed during the spinning process is mounted with its rotor shaft 26 in the bearing gusset of an axially thrust-free support disk bearing 27.
  • the axial positioning of the rotor shaft 26 of the spinning rotor 15 in the bearing gusset of the support disk bearing 27 takes place via a magnetic bearing 31 which is effective on the rotor shaft end.
  • a magnetic bearing 31 is described in detail in DE 197 29 191.0, for example.
  • the magnetic bearing 31 has a stationary bearing component 45 fixed to the spinning housing, which comprises two permanent magnet rings each delimited by pole disks and a rotatable bearing component 32.
  • the rotatable bearing component 32 is, as shown in FIGS. 3 and 4, by a bearing area 33 of the rotor shaft 26 educated.
  • This identification mark 34 can either, as in 3, from a in the area of the rotor cup 35 arranged bar code 36 or, as indicated in Figure 4, from an electronic information carrier 37, for example one so-called transponders exist.
  • FIG Electronic information carrier 37 can for example be built like a small chip card.
  • the electronic information carrier 37 has a transmission and Receive coil 38 and an integrated circuit 39.
  • the Transmitting and receiving coil 38 and the integrated circuit 39 are preferably in an insulating layer 40, for example Glass or the like, embedded. This insulating layer 40 forms a protective coat for the relatively sensitive Electronics.
  • the electronic information carriers 37 are passive per se, that is, they do not have their own energy source.
  • the electronic information carriers 37 are only activated when if they are in the area of a sensor device 41 radiated electromagnetic force field.
  • a transmission device and a Receiving coil of the sensor device 41 and via the transmitting and Reception coil 38 of the electronic information carrier 37 an inductive energy and signal transmission.
  • optical identification marks such as bar codes or the like
  • the great advantage to prevent external influences such as dust, fiber fly etc., largely insensitive and therefore especially for the Use in textile companies are ideal.
  • the control unit 10 locks onto the concerned job 2 and opens with his Release lever 13 first the open-end spinning device 3.
  • a cleaning head 16 is then placed on the spinning housing 20 put on and the spinning cup 35 of the spinning rotor 15 cleaned.

  • the sensor device 41 which, depending on the type of design of the identification marks 34 arranged on the spinning rotors 15, is designed as an optical sensor device, for example as a scanner, as an electronic transmitting and receiving device, as an induction coil, etc., checks the cleaning of the spinning rotor 15 identification mark 34 arranged on the rotor cup 35.
  • electronic information marking 34 this means, for example, that the data recorded by the sensor device 41 is processed in the control device 18 of the operating unit 10, that is to say is compared with data stored in a memory unit 45 connected to the control device 18.
  • the further process of the piecing process depends on the result of this comparison. For example, if the sensor device 41 cannot detect an identification mark 34 on the rotor cup 35 or if the data on the identification device 34 does not correspond to the data stored in the storage unit 45, the control device 18 of the control unit 10 immediately stops the piecing attempt and on the relevant one Spinning station red light set.
