Definitions

  • Spinning ring bearings of the type mentioned above and spinning machines with such spinning ring bearings are, for example, from the EP 3 231 904 A1 known.
  • the ring traveler can be dispensed with entirely and the spinning ring provided for guiding the yarn on the outside, to be arranged floating contactlessly in a magnetic field.
  • the omission of a conventional ring traveler system makes it possible to operate the spinning machines at spindle speeds that are significantly higher than the speeds of known ring traveler systems. There is no limitation of the spindle speed due to the friction conditions between the ring traveler and the yarn to be produced.
  • the object of the invention is to provide a spinning ring bearing and a spinning machine with a spinning ring bearing that has a simple and reliable Positioning of the floating spinning ring allowed.
  • the invention solves the problem by a spinning ring bearing with the features of claim 1 and by a spinning machine with the features of claim 10.
  • Advantageous developments of the spinning ring bearing are specified in the dependent claims 2 to 9.
  • the spinning ring bearing according to the invention has a spinning ring which is arranged coaxially to a spindle axis and whose outer spinning ring peripheral surface is designed to guide a yarn to be wound up on a yarn tube.
  • the yarn is guided past the peripheral surface of the spinning ring along the underside of the spinning ring to the yarn tube, which extends through a central opening in the spinning ring.
  • the spinning ring is held in suspension above the spinning ring support ring and is therefore supported without contact.
  • Characteristic of the spinning ring bearing according to the invention is a guide ring arranged coaxially and at a distance from a peripheral surface of the spinning ring.
  • the guide ring is therefore at least partially - arranged coaxially to the spinning ring - viewed in the direction of the spindle axis - and provides a support surface that can be brought into engagement with the spinning ring peripheral surface via its inner surface, whereby the spinning ring can be moved in the radial direction, i. H. perpendicular to the spindle axis, is held and guided in its position.
  • the distance between the peripheral surface of the spinning ring and the guide ring in the form of an air gap ensures reliable guidance of the yarn along the peripheral surface of the spinning ring during the spinning process.
  • the spinning ring peripheral surface In cooperation with the guide ring, which can be connected to the support ring, formed in one piece with it, but also arranged at a distance from it, the spinning ring peripheral surface thus ensures mechanical guidance and thus stable and simple mounting of the spinning ring in the radial direction compared to one on a spindle arranged twine tube.
  • the bearing is particularly simple and stable and can be produced particularly inexpensively.
  • the spinning ring bearing thus allows particularly high Spindle speeds, as a result of which a particularly high productivity of a spinning machine equipped with a spinning ring bearing according to the invention can be achieved.
  • the spinning ring itself does not rotate or only rotates at a speed that is significantly lower than the spindle speed around the spindle axis.
  • the configuration of the spinning ring bearing for the floating arrangement of the spinning ring can in principle be freely selected.
  • the spinning ring bearing can be designed in such a way that the spinning ring is positioned in a floating manner relative to the spinning ring support ring via an air cushion generated by compressed air.
  • the spinning ring which is formed, for example, from a volatile, permanently magnetizable or non-magnetizable material, is arranged vertically above the spinning ring support ring in the direction of the spindle axis via a magnetic field.
  • the magnetic field generated between the spinning ring support ring and the spinning ring causes a holding force that opposes the weight of the spinning ring and causes the spinning ring to float in its position of use.
  • the use of a magnetic field represents a particularly convenient configuration for the non-contact mounting of the spinning ring relative to the spinning ring support ring, which can also be produced particularly inexpensively.
  • the guide ring is arranged coaxially with the spinning ring, at least in sections, starting from the spinning ring support ring. Accordingly, the spinning ring support ring together with the guide ring forms a cup-like guide, with the spinning ring being guided in the axial direction via the magnetic field advantageously provided between the spinning ring and the spinning ring support ring and in the radial direction via a section of an inner surface of the spinning ring support ring and the spinning ring peripheral surface.
  • the guide ring extends from the spinning ring support ring to an area above the spinning ring.
  • the inner surface of the guide ring facing the peripheral surface of the spinning ring extends, starting from the spinning ring support ring, in the direction of the spindle axis to an area above the upper edge of the spinning ring.
  • the inner surface of the guide ring supports the yarn on the section between, for example, a drafting system outlet and the spinning ring and thus ensures reliable support of the centrifugal forces acting on the yarn during the spinning process.
  • the advantageously provided magnetic field between the spinning ring support ring and the spinning ring can basically be generated in any way.
  • the use of electromagnets is conceivable here, by means of which u. depending on the adjustable current, the distance between the spinning ring and the spinning ring support ring is adjustable.
  • the spinning ring and the spinning ring support ring have permanent magnets arranged opposite one another in the direction of the spindle axis and arranged in a repelling manner.
  • permanent magnets are arranged on the spinning ring support ring and the spinning ring, preferably on the facing surfaces of the spinning ring and spinning ring support ring, in such a way that matching poles face each other.
  • the resulting repulsion between the permanent magnets generates a magnetic field that counteracts the weight of the spinning ring, so that it can be held in suspension relative to the spinning ring support ring.
  • the use of permanent magnets is characterized in that they allow a particularly simple and cost-effective production of a magnetic field that separates the spinning ring from the spinning ring support ring.
  • the use of permanent magnets also has the advantage that there is no need for a complex control and cable feed to the electromagnets.
  • the configuration of the permanent magnets and their arrangement on the spinning ring and the spinning ring support ring can in principle be freely selected.
  • the spinning ring and the spinning ring support ring each have a ring permanent magnet arranged coaxially to the spindle axis and opposite in the direction of the spindle axis, which are aligned to repel one another.
  • the use of ring permanent magnets ensures in a particularly reliable manner a permanently constant magnetic field between the spinning ring and the spinning ring support ring and thus ensures a particularly precise positioning of the spinning ring above the spinning ring support ring.
  • the spinning ring and the guide ring have permanent magnets arranged opposite one another perpendicularly to the spindle axis and aligned in a repelling manner.
  • another magnetic field acting in the radial direction is generated between the spinning ring and the guide ring. H. leads in the radial direction relative to the spindle axis and is thus spaced apart with its spinning ring peripheral surface relative to the inner surface of the guide ring.
  • This embodiment of the invention thus makes it possible in a particularly reliable manner to arrange the spinning ring with its spinning ring peripheral surface at a permanent distance from the inner surface of the spinning ring support ring, so that the yarn to be guided through between the spinning ring peripheral surface and the guide ring is then guided particularly reliably along the underside of the spinning ring to the yarn tube.
  • the supplementary magnetic field ensures that the spinning ring and guide ring are reliably spaced apart.
  • the spinning ring and the guide ring each have a ring permanent magnet which is arranged coaxially to the spindle axis and is arranged opposite one another perpendicularly to the spindle axis and which are arranged repelling one another.
  • the use of ring permanent magnets both on the guide ring and on the spinning ring ensures a particularly reliable radial guidance of the spinning ring during the spinning operation.
  • the radial distance between the spinning ring and the guide ring is 0.05 mm to 5 mm, preferably 0.25 mm is up to 1.5 mm.
  • the advantageously provided particularly small difference in diameter between the outer surface of the spinning ring and the inner surface of the guide ring may only ensure slight tilting, with the spinning ring possibly being supported at two diagonally opposite points on the inner surface of the guide ring. Since the yarn rotates in the guide ring and there is enough space between the spinning ring and the guide ring apart from the aforementioned support points, the yarn can move there and is not clamped, so that a reliable spinning process can be additionally ensured.
  • a particularly advantageous embodiment of the invention provides that the diagonal diameter of the spinning ring is larger than the diameter of the guide ring.
  • the diagonal diameter of the spinning ring namely the diameter with which the spinning ring is supported on the guide ring at two diagonally opposite points, is larger than the diameter of the guide ring.
  • the invention also achieves the object by means of a spinning machine, in particular a ring spinning or ring twisting machine for producing a yarn, with a spinning ring bearing for the coaxial arrangement of the spinning ring with respect to the spindle axis, the spinning ring bearing being designed in the manner described above according to the invention or developed further.
  • the spinning machine according to the invention can be due to the use of the above described according to the invention or further developed spinning ring bearing produce particularly easily and inexpensively.
  • the spinning ring bearing allows the spinning machine to be operated at particularly high spindle speeds, as a result of which a spinning machine can be operated with particularly high productivity.
  • the spinning ring bearing 1a has a guide ring 4a connected in one piece to a spinning ring support ring 3, which adjoins the spinning ring support ring 3 in an outer region and extends in the direction of the spindle axis 7, so that the spinning ring support ring 3 and the guide ring 4a form a pot-like receptacle.
  • a spinning ring 2a is arranged coaxially to the spindle axis 7.
  • permanent magnets 8, 9 are arranged on the spinning ring support ring 3 and vertically opposite on the spinning ring 2a in such a way that a magnetic field with a repelling effect is generated between them, which the vertically acting weight of the spinning ring 2a counteracts and thus keeps the spinning ring 2a in relation to the spinning ring support ring 3 in suspension.
  • the inner surface of the guide ring 4a forms a guide surface for the spinning ring peripheral surface of the spinning ring 2a, so that the guide ring 4a forms a mechanical guide for the spinning ring 2a in the radial direction.
  • the distance between the peripheral surface of the spinning ring and the inner surface of the guide ring 4a is dimensioned such that a yarn 12 can be reliably guided past the peripheral surface of the spinning ring and between the spinning ring 2a and the spinning ring support ring 3 and then reliably wound onto a yarn tube 5 as a yarn winding 6.
  • the radial distance between the peripheral surface of the spinning ring and the inner surface of the guide ring 2a is dimensioned in such a way that at least the yarn to be spun fits through, even if, as in figure 2 shown, the spinning ring 2a is tilted relative to the spindle axis 7, with a sufficient space for the yarn 12 possibly remaining due to a small difference in diameter between the outer surface of the spinning ring and the inner surface of the guide ring 4a.
  • FIG. 3 and 4 Another example of a spinning ring bearing 1b is shown.
  • Spinning ring bearing 1a shown are viewed in the vertical direction to the spindle axis 7 opposite to the guide ring 4b and the spinning ring peripheral surface arranged permanent magnets 10, 11, which generate a repelling magnetic field between the guide ring 4b and the spinning ring 2b.
  • a magnetic field is thus generated via the permanent magnets 10, 11, which aligns the spinning ring 2b in the radial direction, ie perpendicular to the spindle axis 7 with respect to the spindle axis 7.
  • the distance between the peripheral surface of the spinning ring 2b and the inner surface of the guide ring 4b is analogous to that in figure 1 and 2 illustrated embodiment dimensioned such that even with an in figure 4 illustrated tilted state of the spinning ring 2b, a reliable spinning process is ensured after sufficient space remains between the spinning ring 2b and the guide ring 4b in the tilted state, into which the yarn 12 can escape.
  • FIGS figures 5 and 6 Another embodiment of a spinning ring bearing 1c is shown, which differs from that shown in FIGS figures 1 and 2 Spinning ring bearing 1a shown differs in that the guide ring 4c extends from the spinning ring support ring 3 to an area above an upper edge of the spinning ring 2a.
  • the inner surface of the guide ring 4c also serves as a guide for the yarn 12 figures 5 and 6 illustrated embodiment is the distance between the inner surface of the guide ring 4c and the peripheral surface of the spinning ring Spinning ring 2a dimensioned in such a way that even in the tilted, in figure 6 State shown, a sufficiently large space for the yarn 12 remains, so that it can be reliably wound as a yarn winding 6 on the yarn sleeve 5 during the spinning process.
