Definitions

  • the invention relates to a device for producing a piecemeal yarn end on an open-end spinning device of a rotor spinning machine on which a yarn is spun from a sliver presented, wherein the sliver dissolved by means of an opening roller to the single fiber and fed to a vacuum-charged spinning rotor, twisted and from there on Pulled off draw rolls and wound on a cross-wound bobbin, the device has a contact element for mechanically cutting and preparing the yarn end.
  • Rotor spinning machines have long been known and usually consist of a plurality of juxtaposed in series, similar jobs. Each of these jobs has a spinning and winding device at which the presented in a sliver can sliver is spun into a yarn and wound into a cheese.
  • the presented sliver is fed by means of a sliver feed cylinder of the opening roller, which dissolves the sliver in individual fibers with their clothing and transported to the fiber channel of the spin box.
  • the fiber transport is supported by the negative pressure in the rotor housing, which generates an air flow in the fiber channel, releases the fibers from the dissolving set and conveys them into the rotor via the so-called channel plate adapter.
  • the fibers slip into the collecting groove of the rotor, where they are collected according to the set yarn count, drawn off axially through the draw-off nozzle in the axis of rotation and thus twisted into a yarn and wound onto a cross-wound bobbin.
  • the spinning process must be resumed and the yarn end be re-spun to the fiber ring in the collecting groove of the rotor.
  • This so-called piecing can be done either manually or automatically, and although automatic piecing is the most commonly used method today, rotor spinning machines are still in demand, where piecing must be at least partially manual.
  • the yarn end must be found on the cheese and some layers of the yarn are unwound before using a scala determines the required yarn length, the yarn is shortened accordingly and the yarn is prepared for piecing by the individual fibers are released from the fiber composite.
  • the required yarn length is dependent on the diameter of the rotor.
  • a particular disadvantage of this solution is that the preparation of the yarn end is done by means of an entrained by the operator thread preparation device, which carries the risk that it is lost or forgotten and the yarn end can not be prepared as needed.
  • both the DE-OS 25 34 816 as well as the DE-OS 2,203,198 describe rotor spinning machines where manual piecing is required.
  • the rotor spinning machines have a so-called piecing aid, by means of which the yarn unwound from the cross-wound bobbin after a thread break can be measured to the required length and shortened by means of compressed air and prepared for subsequent piecing.
  • a disadvantage of this method is that the shortening and preparation by means of compressed air can not be realized equally well in all yarns; Especially with coarse yarns, these methods are insufficient.
  • such devices require additional clamping and control elements, which in turn represent a complex and costly solution.
  • a disadvantage of this method is that the separation of the length measurement and shortening there is a risk that the yarn is shortened to an incorrect length and thus piecings arise that do not meet the required quality requirements.
  • the object of the invention is therefore to improve the at least partially manual piecing and the piecings of a rotor spinning machine by eliminating sources of error qualitatively and to simplify handling.
  • a contact element for mechanical cutting and preparation of the yarn end is adjustable within the required Garninn Kunststoffes that the stretched yarn end can be measured directly on the contact element and cut to length. This means that according to the invention, the contact element is adjusted to the required yarn length and the yarn end, which was previously removed from the cheese, tensioned and guided to this contact element and thus forcibly reduced to the required yarn length.
  • the yarn is prepared properly for subsequent piecing.
  • the fibers are released from the yarn composite and are present as individual fibers, so that a pieceable yarn end is formed, which can be well bonded to the fiber ring in the collecting groove of the rotor and similar to the yarn produced during the spinning process.
  • the apparatus has a scale for adjusting the contact element to the required yarn length. Based on the scale, the contact element can be easily brought into the position and locked there, which corresponds to the required yarn length.
  • the device for severing the yarn and preparing the yarn end is mounted in close proximity to the sliver feed. This makes it ergonomically very user-friendly and improves the man-machine interface.
  • FIG. 1 a workstation of a rotor spinning machine 1 is shown.
  • Such spinning machines have a plurality of jobs 2, which are each equipped with a spinning device 7 and a winding device 17.
  • the sliver 4 presented in sliver cans 3 is spun into a yarn 5, which is wound on the winding device 17 to form a cross-wound bobbin 22.
  • the winding device 17 has, as is known, a coil frame 18 for rotatably supporting the sleeve of a cross-wound bobbin 22, a bobbin drive roller 19, a Fadenchangier noise 20 and a device 21 for lifting the cross-wound bobbin 22 from the bobbin drive roller 19.
  • the spinning device 7 essentially has a sliver-intake cylinder 8, a sliver-opening roller 9 and a spinning rotor 10.
  • the spinning rotor 10 is mounted in a support disk bearing 11 and is driven by a machine-tangential belt 12.
  • a thread monitor When viewed in the thread running direction, a thread monitor, not shown, and a thread storage device 14 are also provided behind the thread withdrawal device 13.
  • a device 23 is arranged, the contact element 24 of which permits a defined cutting and preparation of a yarn which has been manually retrieved from the cross-wound bobbin 22.
  • FIG. 2 shows the top view of an open-end spinning device 7 according to the invention in the region of the sliver feed.
  • the opening roller is protected by a cover 16 against the penetration of foreign particles.
  • the sliver draw-in cylinder 8 By means of the sliver draw-in cylinder 8, the sliver 4 is transported by the compressor 15, which compresses the sliver 4 at the outlet opening, in the direction of the opening roller 9.
  • the device 23 which can be vertically adjusted to the respectively required yarn length, is used for mechanically cutting to length and preparing the yarn end 6 for subsequent piecing, which contains a grindstone 24.
  • FIG. 3 Analogous to FIG. 2 is in FIG. 3 likewise a top view of an open-end spinning device 7 according to the invention in the region of the sliver feed, but with a yarn end 6 shortened to the required yarn length and prepared for piecing.
  • the yarn 5 produced in the open-end spinning device 7 is pulled out of the rotor 10 by means of a yarn draw-off device 13 through the draw-off nozzle and the draw-off tube and wound on the winding device 17 to form a cross-wound bobbin 22.
  • the rotor 10 Before each piecing, before the yarn end 6 is returned to the spinning device 7, usually the rotor 10 is cleaned to remove accumulated fibers as well as any debris which has a negative effect on piecing, from the rotor 10. This measure is preventive in order to increase the quality of the yarn.
  • the cleaning of the rotor 10 is known from the prior art and therefore not shown here and described approach.
  • the yarn end 6 of the yarn 5 Since the yarn end 6 of the yarn 5 is usually pulled out of the spinning box due to the high winding speed after yarn breakage, the yarn end 6 has to be found on the cross-wound bobbin 22 raised from the bobbin drive roller 19 and some layers of yarn 5 are unwound.
  • the contact element 24 of the device 23 according to the invention is adjusted to the required yarn length, so that now after a yarn break the yarn coming from the cheese 22 tensioned 22 and stopped at the already set to the required yarn length grindstone 24.
  • the yarn 5 By rubbing the yarn end 6 over the grindstone 24, the yarn 5 shortened to the required yarn length required for piecing and optimally prepared for the subsequent piecing, by loosening the fibers from the fiber composite is effected by grinding and thus a pieceable tuft on the yarn end 6 is formed.
  • This yarn end 6 has to be introduced in the direction of the rotor 10, contrary to the normal drawing direction, through the draw-off tube and the draw-off nozzle.
  • the control device of the work station 2 has been activated via an unillustrated switching element, the sliver feed cylinder 8 is driven and the sliver 4 again the opening roller 9 and thus supplied to the rotor 10, in the collecting groove again forms a fiber ring due to the high centrifugal acceleration.
  • the yarn reserve is released from the mechanical yarn storage, not shown, and the prepared yarn end 6 slides in the rotor groove.
