Definitions

  • the present invention relates to a device for a ring spinning or twisting machine with a thread guide ring on which a yarn guide element for rotating and deflecting a running yarn is arranged, and with a receiving unit, on which the yarn guide ring is rotatably mounted about an axis of rotation provided.
  • the invention relates to a yarn guide ring for a ring spinning or twisting machine having a yarn guide for rotating and deflecting a running yarn and a ring spinning or twisting machine.
  • the general task of a ring spinning machine is to impart strength to a fiber structure supplied to it by twisting and to wind the twisted fiber structure in a form suitable for storing, transporting and further processing.
  • the fiber bundle fed to the ring spinning machine is usually a so-called roving, which generally has only a weak protective rotation. From this roving is formed by further twisting a so-called yarn.
  • a twisting machine has the task of twisting a plurality of simultaneously supplied yarns together, so that a so-called yarn is formed.
  • this thread should also be wound up in a convenient form.
  • the thread From stationary thread guide the thread is passed to a thread guide element, which is arranged on a yarn guide ring, and can move on a circular path around the spindle. From the thread guide element, the thread is fed to a sleeve, which is attached to the spindle and rotated by it. As a result, the thread is wound up.
  • the yarn guide ring moves together with Fadengoneelement with respect to the spindle in the axial direction and from.
  • the yarn guide ring is rotatably mounted, wherein the rotation of the yarn guide ring is coaxial with the rotation of the spindle.
  • the thread guide ring does not have its own drive. Rather, it is taken over the hinged to the thread guide thread through the spindle.
  • a device for a spinning or twisting machine with a yarn guide ring which has a trained as a runner yarn guide.
  • the thread guide ring is rotatably mounted on a ring rail.
  • the yarn guide element can slide on a raceway of the yarn guide ring in the circumferential direction.
  • the thread guide element has a greater angular velocity than a main body of the thread guide ring. It is therefore spoken of an asynchronous thread guide ring.
  • the storage of the yarn guide ring is effected by means of a thrust bearing, which is designed as a magnetic bearing, and by means of a radial bearing, which is designed as an aerodynamic bearing.
  • Object of the present invention is therefore to provide a device, a yarn guide ring and a ring spinning or twisting machine, which avoids the disadvantages mentioned and in particular allows a further increase in the spinning speed.
  • the object is solved by the features of the independent claims.
  • force generating means for applying the thread guide ring are provided with axial forces which constantly act during operation of the device and thereby press a trained on the thread guide ring first sliding portion against a corresponding thereto, formed on the receiving unit second sliding portion so as to axially the yarn guide ring to store.
  • the term axial forces refers to such forces, which act parallel to the intended axis of rotation of the yarn guide ring.
  • the force generating means are dimensioned so that the first sliding portion and the second sliding portion constantly abut each other, even if in operation of the device external forces such as yarn tension and weight forces, attack on the yarn guide ring. Whether the force generating means are designed so that they push the yarn guide ring in the direction of the second sliding portion or pull about is immaterial.
  • the first sliding surface and the second sliding surface act in both cases as an axial sliding bearing.
  • Axial movements and tilting movements of the thread guide ring are effectively prevented in the device according to the invention even when the device is operated at high speed.
  • periodic or an aperiodic change in the forces exerted by the thread guide element on the current thread avoided.
  • a drop in the thread tension can be prevented by a movement of the thread guide ring in the direction of yarn guide as well as an increase in the thread tension by a movement of the yarn guide ring away from the yarn guide with the device according to the invention.
  • the number of yarn breaks can be kept low even at a higher speed.
  • the quality of the thread is improved.
  • the thread guide ring apart from the aforementioned uncontrolled touches the thread guide ring with fixed parts, only braked by air friction.
  • the total acting braking torques lead in most cases to a thread tension that is too low for an optimal spinning process.
  • the spindle speed is reduced, the risk that the thread guide ring "overhauled" the spindle.
  • the thread guide ring is subjected to a constant braking force over time.
  • This braking force is the sliding friction force effective between the first and second sliding portions, which depends, inter alia, on the coefficient of sliding friction of the friction partners and the axial forces generated by the force generating means. Consequently, the thread tension can be brought to a value which is favorable for the spinning process by selecting suitable friction partners and a coordinated axial force.
  • friction partners with a relatively low coefficient of sliding friction for example with a sliding friction coefficient of less than or equal to 0.2 equal to 0.1, preferably, since then relatively high axial forces can be applied, which benefits the stable storage of the yarn guide ring.
  • the desired thread tension can be generated and, on the other hand, a "overtake" of the spindle by the thread guide ring can be avoided, without the need for a braking device independent of the bearing.
  • the device according to the invention also makes it possible to brake the thread guide ring without its position having to be changed for this purpose, which would have at least short-term undesired changes in the forces exerted by the thread guide element on the running thread.
  • the speed of the thread guide element corresponds approximately to the sliding speed with which the first and the second sliding section rub against one another.

  • one of the two sliding sections can be designed so that it rests linearly on the respective other sliding section.
  • the first sliding portion is formed as a first sliding surface and the second sliding portion as a second sliding surface, wherein both lie flat against each other in operation of the device. This results in a low-wear device.
  • both the first sliding surface and the second sliding surface have a plurality of surface sections, which are separated from each other, for example by tread grooves.
  • Tread grooves can serve, for example, the cleaning and / or cooling of the sliding sections.
  • the contour of the first sliding surface and the contour of the second sliding surface are preferably rectilinear and perpendicular to the intended axis of rotation.
  • the sliding surfaces are then planar, ie two-dimensional surfaces which run perpendicular to the intended axis of rotation. Such surfaces can be manufactured in a simple manner with high precision.
  • first sliding surface and the second sliding surface may be configured three-dimensionally.
  • first sliding surface and the second sliding surface may be configured three-dimensionally.
  • the contour of the first sliding surface in a said cutting plane is rectilinear and perpendicular to the intended axis of rotation.
  • a similarly advantageous effect can be achieved if the contour of the first sliding surface and the contour of the second sliding surface in the said sectional plane is curvilinear, for example circular-arc-shaped. This also applies if the contour is wave-shaped or zigzag-shaped.
  • a first circular cylindrical surface and on the receiving unit a second circular cylindrical surface is formed on the yarn guide ring, which each have an axis which corresponds to the intended axis of rotation, and which cooperate for the radial guidance of the yarn guide ring.

  • a pressure source is needed for the radial guidance of the thread guide ring
  • the pressure due to the rotation of the thread guide ring itself is generated.
  • only slight frictional forces occur which, moreover, are essentially independent of the radial forces to be absorbed. So it is at best applied a low braking torque on the thread guide ring.
  • the defined via the sliding surfaces introduced braking torque is not significantly changed by radial forces.
  • means are provided for adjusting the axial forces to a fixed value. This allows the optimal processing of different types of threads, without having to replace parts, such as the thread guide ring.
  • the adjustment means can be simple, since the once set value remains constant until a readjustment.
  • means for variably controlling the axial forces are provided.
  • the axial forces when starting the spindle initially have a relatively low value, so as to facilitate a tarnishing of the yarn guide ring.
  • the axial force can then be increased so as to optimize the spinning process.
  • the force generating means are formed so that the line of action of the resulting axial forces generated is congruent with the intended axis of rotation of the yarn guide ring.
  • a particularly kippresistente storage of the thread guide ring is achieved.
  • the force generating means act without contact.
  • the force generating means may act in particular by magnetic forces and / or by generating static and / or dynamic gas pressures, for example air pressures.

  • the magnetically active substance of the permanent magnet rings may comprise hard ferrites or preferably metallic alloys of aluminum, nickel and cobalt or more preferably lanthanides.
  • Hard ferrites for example barium ferrite or strontium ferrite, are available comparatively cheaply.
  • metallic alloy magnets made of aluminum, nickel, cobalt and optionally iron, copper and titanium have a higher specific energy content.
  • Magnets of lanthanides, so-called rare earths have an even higher specific energy content.
  • Magnets of samarium cobalt or of neodymium-iron-boron, for example, are suitable.
  • the higher the specific energy content of a magnet the higher are the fields that can be generated and thus forces with the same volume of the magnet.
  • the size of the device can therefore be reduced by appropriate choice of magnetic materials.
  • the total mass of the thread guide ring or the receiving unit can be reduced.

  • the annular holder is fastened by means of a threaded arrangement or a bayonet arrangement on the base body, so that the axial position of the holder can be changed by turning the holder.
  • the thread assembly or bayonet assembly can be designed so that the axial position of the second magnetic ring changes by about 2 mm when the holder is rotated by 90 °.
  • the receiving unit may have an annular pressure chamber, which is acted upon by an overpressure, which acts on a side facing away from the first sliding portion of the yarn guide ring, so as to generate the axial forces.
  • the annular pressure chamber may, for example, have a U-shaped cross section into which the section of the thread guide ring protrudes.
  • the pressure chamber may also be formed as a gap between the receiving unit and the corresponding portion of the yarn guide ring, wherein a limitation of the pressure chamber in the radial direction is possible, but not essential. Overall, many forms for the pressure chamber are conceivable. However, it is only essential that it is designed such that an overpressure acting in it presses the first sliding section and the second sliding section in the axial direction towards each other.

  • Rotor and thread guide ring rotate during operation by the same axis of rotation provided, but the rotor rotates at a higher angular velocity. Since the relative speed between the sliding sections is reduced, a particularly low-wear bearing of the thread guide ring results.
  • the thread guide ring according to the invention comprises a leveling compound for compensation of radial forces.
  • the resulting radial force occurring during operation of the yarn guide ring can be lowered. This leads to a smooth running of the yarn guide ring, especially at high spinning or twisting speeds, so that the mentioned disadvantages are avoided.
  • the thread guide ring according to the invention is particularly suitable for the above-described device according to the invention, since unwanted braking forces, such as by friction in a radial sliding bearing, are avoided by reducing the radial forces.

Thread guiding ring and bodies rotate at the same angular velocity. Since no friction occurs between the thread guide element and the thread guide ring, heating of the thread guide element is avoided.
