Definitions

  • the invention relates to a drive roller for a textile machine producing cross-wound bobbins, particularly such a drive roller for the frictional drive of a cross-wound bobbin held so as to rotate in a creel of a winding device.
  • Drive rollers for the frictional drive of a cross-wound bobbin held to rotate in a winding device of a textile machine have been known for a long time.
  • Various embodiments of drive rollers of this type are described in the patent literature.
  • German Patent Publications DE 30 15 207 C1 or DE 100 26 388 A1 describe guide rollers, for example, which consist substantially of a central drive roller body, two laterally arranged, relatively soft drive coverings and two connection elements which can be fixed to the central roller body.
  • the central drive roller body is fixed here in a frictionally engaged or positive manner, on a drive shaft.
  • all the drive rollers of one machine side are fixed in a rotationally engaged manner on a common drive shaft along the machine, said shaft being connected in turn to a common drive.
  • drive rollers which are driven by a single motor are also known for winding machines.
  • Drive rollers of this type known, for example, from German Patent Publication DE 43 36 312 C2 are generally configured as yarn guide drums, in other words as components which both rotate the cross-wound bobbin and also traverse the yarn that is running on.
  • Such yarn guide drums generally have a yarn-smooth peripheral face, on which the cross-wound bobbin rests with a certain contact pressure and is entrained in a frictionally engaged manner by the driven yarn guide drum.
  • German Patent Publication DE-PS 593 358 it is known from German Patent Publication DE-PS 593 358, to use drive rollers, the electric motor single drives of which are configured as external rotors, to rotate cross-wound bobbins and to traverse the yarn that is running on.
  • German Patent Publication DE-PS 593 358 shows various embodiments of such yarn traversing and cross-wound bobbin drive devices driven by a single motor, with a drive configured as an external rotor.
  • a bearing block between the bearing points of which a hollow axle is fastened, is arranged in the region of the winding device of the winding machine in the embodiment according to FIG. 4 of German Patent Publication DE-PS 593 358.
  • the stator of an electric drive is fixed to this axle.
  • the axle also forms the counter bearing for the bearing of the drive rotor configured as an external rotor.
  • the cross-wound bobbin rests directly on the housing of the external rotor and, during operation, is entrained by the rotating housing of the external rotor in a frictionally engaged manner.
  • This very compact drive roller also has the disadvantage that, during operation, in particular in acceleration phases, undefined slippage often occurs between the rotor housing, that is designed yarn-smooth on its surface, and the cross-wound bobbin, wherein the groove required for yarn traversing only reduces the driving surface and accordingly further reduces the friction.
  • “Yarn-smooth” in the present case is taken to mean a surface, which is, for example, so polished that is has no edges or corners, on which the yarn to be wound on could catch.
  • Drive rollers with a rough surface are ruled out however, as without a yarn-smooth surface of these drive rollers, proper traversing of the yarn is not possible.
  • Drive rollers with a yarn-smooth profiling on their surface have also not previously been used in practice as the manufacturing methods which were previously conventional in the textile machine industry did not allow the production of drive rollers with a yarn-smooth profiling at reasonable costs.
  • the invention is based on the object of developing a drive roller with a good service life and high entraining force.
  • a drive roller is to be provided, which has an economically producible, yarn-smooth and stable profiling.
  • a drive roller for a textile machine producing cross-wound bobbins for the frictional drive of a cross-wound bobbin held so as to rotate in a creel of a winding device.
  • the outer periphery of the drive roller is formed by a thin-walled metal tube profiled by high-pressure internal forming.
  • the embodiment according to the invention has the advantage, in particular, that a thin-walled, abrasion-resistant metal tube can be provided in an economical manner with a yarn-smooth profiling by means of high-pressure internal forming and can thus be fixed on the outer periphery of a drive roller, such that the profiling of the drive roller virtually forms a positive fit with the cross-wound bobbin to be driven.
  • the profiling produced by high-pressure internal forming, of the thin-walled metal tube is thus immediately yarn-smooth without any post-treatment.
  • High pressure internal forming is a production method known per se in conjunction with hollow bodies, which allows relatively economical, reproducible production even of complicated components.
  • a hollow body made of a cold-formable metal is placed in the mould cavity of a die and then pressed onto the die wall by means of pressure fluid, which is injected at high pressure.
  • the die wall thus has according to the desired profiling of the tube, hollows, into which the material of the tube is pressed during the forming process with the formation of uniform, smooth radii.
  • a drive roller can be produced simply and economically by the configuration of a drive roller according to the invention, said drive roller having a long service life and wherein the slippage generally occurring between the drive roller and cross-wound bobbin is minimized.
  • Metal tubes manufactured from such materials are not only corrosion-resistant, but also relatively abrasion-resistant, so profile wear is kept within reasonable limits. In other words, the profiling in metal tubes of this type has a long service life. Moreover, metal tubes of this type are very substantially insensitive to rust.
  • the drive roller is acted upon by an electric motor single drive configured as an external rotor and the thin-walled profiled steel tube is fixed directly to the outer periphery of the rotor housing of the external rotor.
  • Drive rollers configured in this manner have the advantage, in particular, that the drive rollers only require relatively little installation space owing to their internally located drive, and this is advantageous with respect to the known restricted space conditions at the workstations of a textile machine producing cross-wound bobbins.
  • By using a thin-walled steel tube profiled by high-pressure internal forming it is moreover possible, to equip the drive rollers economically in such a way that they develop a high entraining force and this has positive effects, in particular when accelerating large cross-wound bobbins.
  • the centrifugal mass of the external rotor is only increased insubstantially, in this case.
  • the wall thickness of the thin-walled metal tube is between 0.1 mm and 0.4 mm, preferably 0.2 mm. Hollow bodies with such a relatively small wall thickness can be processed relatively problem-free by high-pressure internal forming, on the one hand, but, on the other hand, after their profiling and when they have been drawn onto their support body, for example the rotor housing, have the necessary strength.
  • the profiling of the metal tube is stepped at least in the direction of rotation of the drive roller.
  • the profiling consists of a large number of nubs or webs arranged spaced apart at least in the direction of rotation.
  • a configuration of this type makes it possible for the profiling of the metal tube to be able to “dig in” slightly into the surface of the cross-wound bobbin resting with a certain contact pressure on the drive roller and to thus virtually form a positive fit with the cross-wound bobbin.
  • the metal tube may have nubs, for example, in its central region, while webs are incorporated into the side regions of the metal tube.
  • the cross-wound bobbin is thus entrained relatively gently during the spinning operation, via the webs.
  • the webs may also be arranged in the central region of the metal tube. Gentle entraining of the conical cross-wound bobbin during the spinning process is also ensured in this case.
  • nubs extend uniformly over the entire surface of the steel tube.
  • a configuration of this type also ensures reliable entraining of the abutting cross-wound bobbin to be driven.
  • the slippage between the drive roller and cross-wound bobbin is kept within limits both during uniform operation and in the acceleration or deceleration phases of the winding device.
  • FIG. 1 shows a side view of a half section of a textile machine producing cross-wound bobbins
  • FIG. 2 shows a perspective view of a workstation of a textile machine producing cross-wound bobbins
  • FIG. 3A shows a drive roller with a first embodiment of a thin-walled steel tube which is profiled by high-pressure internal forming and fixed to the rotor housing of an external rotor,
  • FIG. 3B shows a drive roller with a further embodiment of a thin-walled steel tube which is profiled by high-pressure internal forming and fixed to the rotor housing of an external rotor,
  • FIG. 4 shows the drive roller according to the invention with a thin-walled steel tube in section.
  • FIG. 1 schematically shows a side view of half a textile machine 1 producing cross-wound bobbins, an open end rotor spinning machine in the embodiment.
  • Textile machines of this type have, as known, a large number of similar workstations 2 between their end frames, not shown.
  • the workstations 2 in each case, have here a spinning unit 3 and a winding device 4 .
  • Fiber bands 6 such as commonly known as slivers, which are stored in spinning cans 5 are processed in the spinning units 3 to form yarns 7 , which are then wound onto the winding devices 4 to form cross-wound bobbins 8 .
  • the finished cross-wound bobbins 8 are conveyed via a cross-wound bobbin conveying mechanism 12 to a loading station (not shown) arranged at the end of the machine.
  • the workstations 2 also have further handling mechanisms in each case, apart from the spinning unit 3 and the winding device 4 , for example a yarn draw-off mechanism 10 , a suction nozzle 17 , a yarn store 13 and a waxing mechanism 14 .
  • a yarn draw-off mechanism 10 for example a yarn draw-off mechanism 10 , a suction nozzle 17 , a yarn store 13 and a waxing mechanism 14 .
  • the function of this component is known and described in detail in numerous patents.
  • the winding device 4 has a deflection roller 15 , a yarn traversing mechanism 16 , with a yarn guide 18 , a drive roller 11 and a creel 9 .
  • the drive roller 11 which is acted upon in the embodiment by a single motor and is not described in more detail in FIGS. 3 and 4 , in this case drives a cross-wound bobbin 8 that is mounted so as to rotate freely in the creel 9 .
  • the drive roller 11 has an external rotor drive 22 , in other words, the stator 25 of an electric motor drive is fixed in a rotationally engaged manner to a bearing axle 24 , which is arranged in a rotationally engaged manner, and is connected via power line 26 to a current source (not shown).
  • Bearing mechanisms 27 for the rotor 23 of the drive roller drive 22 are also positioned on the bearing axle 24 .
  • the rotor 23 has a rotor housing 28 , on the outer periphery 21 of which is fixed a thin-walled metal tube 19 , which is profiled by high-pressure internal forming, preferably a steel tube made of a high-grade steel alloy.
  • the thin-walled, profiled steel tube 19 is in contact with the surface of the cross-wound bobbin 8 and entrains it.
  • the profiling of the thin-walled steel tube 19 consists here, for example, as indicated in FIG. 3A of nubs 20 which are arranged distributed over the entire periphery of the steel tube 19 , positioned spaced apart and which “dig in” into the surface of the cross-wound bobbin 8 in a virtually positive manner and therefore ensure that there is always adequate entraining force between the driving drive roller 11 and the driven cross-wound bobbin 8 .
  • the thin-walled steel tube 19 has regions with different profiling.
  • Webs 30 which are spaced apart in the direction of rotation R of the drive roller, are arranged, for example, in the side regions 32 , 33 of the steel tube 19 , while a profiling in the form of spaced nubs 20 is present in the central region 31 .
  • the webs 30 are arranged in the central region of the steel tube 19, while the outer regions are smooth or provided with nubs 20.
  • the thin-walled steel tube 19 advantageously receives its profiling by means of high-pressure internal forming.
  • this method which is known per se and described, for example, in German Patent Publication DE 41 03 082 A 1 and which is also called hydrostatic forming, a hollow body consisting of cold-formable metal is inserted into a die, into which recesses are incorporated, corresponding to the desired profiling.
  • the thin-walled tube is pressed into the recesses present on the inner wall of the die by means of an incompressible medium, preferably a pressure fluid, which is injected at very high pressure into the interior of the hollow body.
  • an incompressible medium preferably a pressure fluid
