Definitions

  • the invention relates to an open-end spinning device a spinning rotor rotating in a rotor housing and one arranged coaxially to the rotor axis, with respect to the spinning rotor rotatable spinning insert according to the generic term of Claim 1.
  • the generic DE 44 11 342 A1 also describes one Open-end rotor spinning device with one rotatable in the spinning rotor stored spinning insert.
  • the spinning insert is over one Coupling device can be temporarily fixed on the spinning rotor. there is the spinning insert in normal spinning operation by the rotating thread leg driven.
  • By means of the Coupling device it is possible in the Acceleration phase of the spinning device on the spinning insert Accelerate rotor speed by passing through the Spinning rotor is taken. This will overload the Thread during piecing, leading to thread breakage or too can lead to failure of the piecer.
  • the Clutch is as a centrifugal clutch or alternatively as Electromagnetic clutch formed, with spring elements causes a frictional connection between the spinning rotor and the spinning insert becomes.
  • the length of time the spinning insert is taken along by the Spinning rotor must be set and defined corrected later if necessary.
  • To the Spring elements and the spinning rotor can be a disadvantage Roughening the surface and after a long period of operation Wear occur.
  • the release of the clutch and thus that Removal of the one connecting the spinning rotor and the spinning insert Friction is not exactly to the desired extent Time of thread binding during piecing tunable. After the connection, the coupling must be released, thus different orbital speeds of spinning rotor and spinning insert are possible.
  • the clutch is released too late can lead to faulty piecers.
  • the Invention Based on the aforementioned prior art, the Invention, the object of an improved open-end rotor spinning device to accomplish.
  • Open-end spinning devices are the subject of the subclaims.
  • An open-end spinning device designed according to the invention is no wear or scratching Surface of the spinning rotor with the possible consequence unwanted fiber or dust accumulation in the rotor exposed. Additional drive devices as well Control devices for drive or clutch are not required.
  • the permanent magnets are not releasably attached to the spinning insert.
  • the space requirement of the Permanent magnet is low. These are easy in the spinning insert to integrate and do not require any additional installation space. This is particularly advantageous because the available Installation space within the spinning rotors is very limited.
  • the spinning insert rotates freely within the spinning rotor a guide channel according to claim 4 for the to be deducted Thread on. This makes the spinning insert off the thread advantageous reliably dragged along, and the thread lies relatively protected. The free thread end is also during the piecing process of the piecing thread when inserted through the guide channel guided.
  • the open-end spinning device 1 shown in FIG. 1 has a spinning rotor 2.
  • the spinning rotor 2 includes one Rotor plate 3 and a rotor shaft 4.
  • the rotor shaft 4 is stored in a support disc bearing 5 and in axial Direction fixed by a thrust bearing 6.
  • the drive of the Spinning rotor 2 takes place via an endless flat belt 7
  • Rotor housing 9 forms a vacuum chamber 8 in which the Rotor plate 3 rotates.
  • the rotor housing 9 is a Vacuum line 10 connected to a vacuum source 11.
  • the rotor housing 9 is during the spinning operation by a Channel plate 12 by means of an annular seal 13 airtight locked.
  • the channel plate 12 has one Channel plate extension 14 in which a thread take-off nozzle 15 and a thread take-off tube 16 are held.
  • a spinning insert 18 is rotatable within the rotor plate 3 arranged on the rotor shaft 4.
  • the spinning insert 18 instructs its front a recess 19 into which the Thread take-off nozzle 15 protrudes. From the recess 19 starting, runs essentially radially Thread guide channel 20 to the outer edge of the spinning insert 18.
  • FIG. 2 shows a partial view of an inventive Open-end spinning device with a spinning rotor 21.
  • the rotor plate 22 of the spinning rotor 21 is a spinning insert 24 rotatable on the rotor shaft 23 by means of a roller bearing 25 stored.
  • the roller bearing 25 is by means of its inner ring a bolt 26 is attached to the rotor shaft 23.
  • the Rolling bearing 25 and the bolt 26 are by a Cover disc 27 closed against the thread take-off nozzle 28.
  • the thread take-off nozzle 28 is on the channel plate extension 29 attached. This closes the thread take-off nozzle 28 Thread take-off tube 30.
  • the spinning insert 24 has one Thread guide channel 31.
  • Spinning insert 24 also includes four cylindrical permanent magnets 32, the diametrical and in the same distance from the rotor axis 33 are arranged.
  • Open-end rotor spinning devices are known to be made after a Thread break due to an automatically operating piecing carriage, as described for example in DE 44 11 342 A1, newly spun.
  • a suitably prepared Thread end through the thread take-off tube 30 in the Spinning rotor 21 introduced.
  • the thread end comes over the Thread guide channel 31 of the rotating with the spinning rotor 21 Spinning insert 24 for the fiber collecting groove 34 of the spinning rotor 21 and there lies down on the formed from single fibers Fiber ring.
  • the individual fibers are through the fiber guide channel 35 pneumatically conveyed into the rotor plate 22 and lie down there in the fiber collecting groove 34.
  • the spinning insert 24 is through the magnetic effect of the permanent magnets 32 taken along and rotated in the same direction as the spinning rotor 21 in the direction of arrow 37.
  • the spun thread is over the thread take-off nozzle 28 and the thread take-off tube 30 is withdrawn.
  • the thread runs through the thread guide channel 31.
  • By pulling the spun thread is the spinning insert 24 by the thread dragged. If the spinning rotor 21 on his Operating speed accelerates, the spinning insert 24th also accelerated in the same direction of rotation.
  • the Orbital speed of the spinning insert 24 of the 2 and 3 results largely from the rotational speed of the Fiber collecting groove 34 plus the respective Yarn withdrawal speed. Engaging or disengaging is not required. The rotational movement of the spinning insert 24 provides yourself.
  • the invention is not based on those described Embodiments limited. It is special with regard to the formation of the spinning insert Embodiments possible within the scope of the invention.
