Definitions

  • the invention relates to a thread take-off roller for a cheese-producing textile machine according to the preamble of claim 1.
  • Textile machines producing cross-wound bobbins in particular open-end spinning devices, have thread removal devices in the region of their work stations, which extract the thread produced in a spinning device from the spinning device and convey it in the direction of a winding device where the thread is wound into a cross-wound bobbin.
  • the known thread withdrawal devices have either, as in the DE 44 32 240 A1 described over a machine-length drive shaft or the thread take-off devices are driven by a single motor.
  • Such a thread withdrawal device is for example the subject of DE 101 39 075 A1 ,
  • the thread withdrawal devices according to DE 44 32 240 A1 each consist of a relatively thick-walled, hardened and chrome-plated trigger sleeve, which is rotationally fixed in the field of jobs on the machine-length drive shaft and a pivotally mounted, rubber-tyred pressure roller, which is taken from the trigger sleeve over frictional engagement.
  • these known thread withdrawal devices have the disadvantage that they are suitable due to the continuous drive shaft only for removing the thread during regular spinning operation, but not for a return of the thread end in the spinning device in connection with the piecing process.
  • Thread withdrawal devices with a single-motor driven thread take-off roller are, for example, in DE 101 39 075 A1 described. These known thread withdrawal devices each have a relatively large, single motor driven thread take-off roller and a much smaller, pivotally mounted pinch roller.
  • the thread take-off roll which can be reversibly driven by a stepping motor, consists of a rotationally symmetrical die-cast or injection-molded body, the outer circumference of which is processed in a thread-smooth manner and is preferably chrome-plated.
  • a disadvantage of these known thread take-off devices are, above all, the production costs of the thread take-off rollers. That is, the necessary, relatively complex processing of the coming into contact with the thread surface makes such thread withdrawal rollers relatively expensive.
  • the DE 198 41 666 A1 discloses a thread withdrawal roller according to the preamble of claim 1.
  • the present invention seeks to develop a thread take-off roll with smooth-running surface, which is inexpensive to produce.
  • a thin-walled, made of an abrasion-resistant material metal ring is provided in a cost-effective manner first by means of high-pressure internal deformation with a profiling and then set on the outer periphery of a rotationally symmetrical body of the thread take-off roll.
  • the profiling of the thin-walled metal ring created by high pressure internal deformation is immediately smooth as a thread without any subsequent treatment.
  • High-pressure internal deformation is a production method known per se in connection with hollow bodies, which enables a relatively cost-effective, reproducible production of even complicated components.
  • a hollow body made of a cold-formable metal is inserted into the mold cavity of a die and then pressed by pressure fluid which is injected at high pressure to the Gesenkwandung.
  • the Gesenkwandung has in accordance with the desired profiling of the tube elaborations, in which the material of the tube is pressed during the forming process to form uniform, smooth radii.
  • the high-pressure internal deformation thus represents a process which makes it possible to produce hollow bodies precisely and inexpensively.
  • the material for the metal ring has, as set forth in claim 2, steel, preferably an alloy of a so-called stainless steel proven.
  • metal rings are not only very resistant to corrosion, but also relatively abrasion resistant, so that the wear of the profiling holds within reasonable limits.
  • these metal rings are not only largely insensitive to rust, but in such metal rings, the profiling has a long life.
  • the wall thickness of the thin-walled metal ring is between 0.1 mm and 0.4 mm, preferably 0.2 mm.
  • Hollow body with such a relatively small wall thickness can be edited relatively easily on the one hand by Hochlichinnenverformung, but on the other hand have their profile and when they are mounted on their support body, for example, the main body of the thread take-off roll, the required rigidity.
  • the profiling of the metal ring preferably consists of a plurality of spaced apart in the direction of rotation webs. About the webs takes a relatively gentle entrainment of the thread in its withdrawal from the spinning device. Due to the profiling of the metal ring, the slip between the thread take-off roll and the thread is kept within narrow limits both during the uniform operation and during the acceleration phases of the winding device.
  • the high-pressure internally deformed metal ring is coated. By such a coating, the life of the metal ring can be extended.
  • FIG. 1 shows a perspective view of a job of an open-end rotor spinning machine.
  • the job is characterized in total with the reference number 1.
  • Such jobs 1 have, as known and therefore shown only schematically, essentially an open-end spinning device 2 for producing a thread 9 and a winding device 3, which makes it possible to wind the thread 9 to form a cheese 8.
  • the thread 9 produced in the open-end spinning device 2 is withdrawn from the open-end spinning device 2 by a thread withdrawal device 27 which has a drivable thread withdrawal roller 10 and a pinch roller 14 that can be pivoted to the thread withdrawal roller 10.
  • the thread 9 leaves the open-end spinning device 2 through a so-called thread withdrawal tube 21st In the area of the open-end spinning device 2 also a pivotally mounted Anspinhtosorgan 16 is arranged, which takes over after a yarn break the retrieved by a suction nozzle 4 of the cheese 8 thread 9 and prepares the yarn end for piecing.
  • a thread monitor 26 a paraffining device 62 and thread storage devices 60 and 61 are arranged in the direction of yarn travel behind the thread take-off device 27.
  • the yarn storage device 61 is designed as a vacuum-pressurized storage nozzle, while the storage device 60 is designed as a mechanical yarn storage. That is, between two stationary Fadenleitorganen an adjustable Fadenleitorgan is arranged, which, acted upon by a stepping motor 58, is arranged to be movable relative to the yarn path.
  • the winding device 3 consists, as usual, from a bobbin frame 22 for rotatably supporting a cross-wound bobbin 8, a preferably driven by a reversible single drive 56 drive drum 23 and a Fadenchangier Nur 24, which is driven for example via a stepping motor 57.
  • a thread-centering device in the form of a pivotally mounted centering plate 17 can also be arranged, which can be folded in the regular yarn path when required by a drive 55.
  • the workstation 1 has a suction nozzle 4, which is adjustable by means of a stepping motor 6 between a thread receiving position lying in the region of the winding device 3 and a yarn transfer position lying in the region of the spinning device 2.
  • the individual stepper motors are, as indicated, connected via control lines to a winding station computer 25.
  • the thread withdrawal device 27 which in the FIGS. 2 and 3 consists essentially of one, by a stepper motor 13 driven Fadenabzugsrolle 10 and from a to the thread withdrawal roller 10 can be swiveled pinch roller 14.
  • the thread take-off device 27 provides both for the removal of the spun yarn. 9 from the open-end spinning device 2 during the regular spinning operation, as well as the Wiederanspinnen for the return of a prepared thread 9 in the open-end spinning device. 2
  • the thread take-off roll 10 consists in detail of a rotationally symmetrical, for example, die-cast base body 15, on the outer circumference 7 a thin-walled, profiled by high-pressure internal deformation metal ring 11, which preferably consists of steel or a stainless steel alloy is fixed.
  • the thin-walled, profiled metal ring 11 is in contact with the thread 9 during the winding operation and, in conjunction with the adjacent pressure roller 14, ensures that thread 9 is continuously withdrawn from the open-end spinning device 2.
  • the profiling of the thin-walled metal rings 11 preferably consists, as in the FIGS. 2 and 3 indicated, distributed over the entire circumference of the metal ring 11 webs 12, spaced apart in the direction of rotation R of the drive roller to each other.
  • the thin-walled metal ring 11 receives its profiling advantageously by high-pressure internal deformation.
  • a cold ausformbarem existing metal hollow body is placed in a die, in which, according to the desired profiling, recesses are incorporated.
  • an incompressible medium preferably a pressure fluid which is pressed with very high pressure into the interior of the hollow body
  • the thin-walled tube is pressed into the existing on the inner wall of the die recesses. That is, the formation of the inner wall of the die gives the final shape of the component to be created both in terms of its dimensions or its exact physical configuration before.
