Definitions

  • the invention relates to a drive roller for a cheese-producing textile machine according to the preamble of claim 1.
  • Drive rollers for the frictional driving a rotatably supported in a winding device of a textile machine cheese have been known for a long time.
  • the patent literature describes various embodiments of such drive rollers.
  • drive rollers which consist essentially of a central drive roller body, two laterally arranged, relatively soft drive linings and two fixable on the central drive roller body connecting elements.
  • the middle drive roller body is frictionally or positively fixed to a drive shaft. That is, in this case, all the drive rollers of a machine side are rotationally fixed on a common, machine-length drive shaft, which in turn is connected to a common drive.
  • drive rollers which are driven by a single motor.
  • Such, for example by the DE 43 36 312 C2 known drive rollers are usually designed as a thread guide drums, that is, as components that rotate both the cheese and oscillate the winding thread.
  • Such thread guide drums generally have a thread-smooth peripheral surface on which the cross-wound bobbin rests with a certain contact pressure and is frictionally entrained by the driven thread guide drum. Since a certain slip between the drive roller and cross-wound bobbin is inevitable in such thread guide drums, the acceleration capacity of such drive arrangements, in particular when the cheeses have already reached a large diameter and thus a significant weight, limited.
  • the in the DE-PS 593 358 shown and described winding machine shows various embodiments of such a single motor driven Fadenchangier- and cheese packages drive designed as an external rotor drive.
  • a bearing block is arranged, between the bearing points of which a hollow axis is fastened.
  • the stator of an electric drive is set.
  • the axis also forms the abutment for the storage of trained as an external rotor drive rotor.
  • the cross-wound bobbin rests directly on the housing of the external rotor and is frictionally entrained during operation by the rotating housing of the external rotor.
  • this very compact drive roller has the disadvantage that during operation, especially in acceleration phases, between the smooth on its surface designed rotor housing and the cross-wound often undefined slip occurs, the required for the Fadenchang réelle groove only reduces the driving surface and consequently the friction is further reduced.
  • “smooth-running” is understood to mean a surface which, for example, is polished in such a way that it has no edges or corners at which the thread to be wound up might become stuck.
  • the DE 10159613A discloses a support body according to the preamble of claim 1. In order to drive a cross-wound reel as low as possible, it would be desirable to provide drive rollers with a relatively rough or with a profiled surface, so that between the drive roller and the cheese quasi quasi a form fit is given.
  • drive rollers with a rough surface are ruled out, since without a smooth-running surface of these drive rollers proper traversing of the thread is not possible.
  • Even drive rollers with a thread-smooth profiling on their surface are not yet in practice in use, since the usual in the textile machinery industry manufacturing processes did not allow the production of drive rollers with a thread-smooth profiling at a reasonable cost.
  • the present invention seeks to develop a drive roller with good service life and high driving force.
  • a drive roller is to be created, which has an economically producible, smooth-running and stable profiling.
  • the embodiment of the invention has the particular advantage that a thin-walled, abrasion-resistant metal tube by means of high-pressure internal deformation provided in a cost-effective manner with a thread-smooth profiling and can be set on the outer circumference of a drive roller, that the profiling of the drive roller quasi form a positive connection with the cheese to be driven.
  • the profiling of the thin-walled metal tube 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 thin-walled steel tube immediately shows its final, thread-smooth profiling, eliminating the need for further processing steps.
  • high-pressure internal deformation is a process that makes it possible to produce hollow bodies precisely and inexpensively. That is, the inventive design of a drive roller can be created in a simple and cost-effective manner, a drive roller having a long life and in which the slip usually occurring between drive roller and cross-wound bobbin is minimized.
  • metal pipes are not only very resistant to corrosion, but also relatively resistant to abrasion, so that the wear of the profiling keeps within reasonable limits. That is, in such metal pipes profiling has a long life, also such metal pipes are largely insensitive to rust.
  • the drive roller is acted upon by an electromotive, designed as an external rotor single drive and the thin-walled, profiled steel pipe is set directly on the outer circumference of the rotor housing of the external rotor.
  • Such trained drive rollers have the particular advantage that the drive rollers require relatively little installation space due to their internal drive, which is very advantageous in view of the known cramped space at the work cheesemaking-producing textile machine.
  • By using a thin-walled, profiled by high-pressure internal deformation steel pipe it is also possible to equip the drive rollers cost-effective so that they develop a high driving force, which has a very positive effect especially when accelerating large cheeses.
  • the wall thickness of the thin-walled metal tube 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 easily on the one hand by high-pressure internal deformation, but on the other hand have the required strength on account of their profiling and if they are mounted on their supporting body, for example the rotor housing.
  • the profiling of the metal tube is discontinued at least in the direction of rotation of the drive roller. That is, the profiling consists of a plurality of spaced at least in the rotational direction of spaced knobs or webs.
  • the profiling of the metal tube is "dig in” somewhat in the surface of the cross-wound bobbin resting on the drive roller with a certain contact pressure, thereby virtually forming a positive connection with the cross-wound bobbin.
  • the metal pipe may, for example, in its middle region nubs, while in the side regions of the metal tube webs are incorporated. About the webs takes a relatively gentle entrainment of the cheese during spinning operation.
  • nubs extend uniformly over the entire surface of the steel pipe. Even such training ensures safe entrainment of the resting, to be driven cheese. That is, due to the profiling of the metal tube, the slip between the drive roller and cross-wound bobbin is limited both during steady state operation and in the acceleration and deceleration phases of the winding device.
  • the invention is not limited to the above-described types of profiling of the metal pipe, but quite other types of profiling, e.g. Nubs in the side areas and webs in the middle, to fall under the general inventive concept.
  • FIG. 1 is a schematic side view of a half of a cross-wound producing textile machine 1, in the embodiment of an open-end rotor spinning machine, shown.
  • Such textile machines have, as is known, between their (not shown) end frames over a plurality of similar jobs.
  • the work stations 2 each have a spinning unit 3 and a winding device 4.
  • the finished cross-wound bobbins 8 are conveyed via a cross-wound bobbin transport device 12 to a loading station (not shown) arranged on the machine end side.
  • the work stations 2 each have, in addition to the spinning unit 3 and the winding device 4, further handling devices, for example a thread withdrawal device 10, a suction nozzle 17, a yarn store 13 and a waxing device 14.
  • further handling devices for example a thread withdrawal device 10, a suction nozzle 17, a yarn store 13 and a waxing device 14.
  • the winding device 4 has a deflection roller 15, a thread-changing device 16, with a thread guide 18, a drive roller 11 and a winding frame 9.
  • the drive roller 11 acted upon by a single motor in the exemplary embodiment, which is shown in greater detail in FIGS. 3 and 4, drives a cross-wound bobbin 8 freely rotatably mounted in the creel 9.
  • the drive roller 11 has an external rotor drive 22, that is, on a rotationally fixed bearing axis 24 is rotatably fixed the stator 25 of an electric motor drive, which is connected via power line 26 to a (not shown) power source.
  • bearing shaft 24 On the bearing shaft 24 also bearing means 27 are positioned for the designed as an external rotor rotor 23 of the drive roller drive 22.
  • the rotor 23 has a rotor housing 28 on the outer circumference 21 of a thin-walled, profiled by high-pressure internal deformation metal tube 19, preferably a steel tube made of a stainless steel alloy, is fixed.
  • the thin-walled, profiled steel tube 19 is in contact with the surface of the cross-wound bobbin 8 during the winding operation and carries it along.
  • the profiling of the thin-walled steel tube 19 consists, for example, as indicated in Figure 3A, distributed over the entire circumference of the steel tube 19 arranged spaced spaced nubs 20, the quasi form-fitting "buried" in the surface of the cheese 8 and ensure that that between the driving drive roller 11 and the driven cheese 8 is always sufficient driving force available.
  • the thin-walled steel tube 19 has regions with different profiling.
  • the side regions 32, 33 of the steel tube 19 for example, webs 30 spaced apart in the direction of rotation R of the drive roller are arranged, while in the middle region 31 there is a profiling in the form of spaced knobs 20.
  • the webs 30 are arranged in the central region of the steel tube 19, while the outer regions are smooth or provided with knobs 20.
  • the thin-walled steel tube 19 is advantageously profiled by high-pressure internal deformation.
  • the DE 41 03 082 A1 described method which is also referred to as hydrostatic forming, one from cold-formable metal existing hollow body inserted into 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.
