Definitions

  • This invention relates to a centering and locking element provided on the spindle to receive a tube thereon, this centering element being an open elastic ring of polygonal shape connected to the spindle by means of a thin annular groove which contains said elastic ring.
  • the operating faces comprise a plurality of spindles carrying the tubes on which the spun yarn is wound.
  • Each spinning spindle comprises a rotating part which receives and retains the tube and rotates it during operation.
  • the rotating part is approximately as long as the tube and is provided with elements to retain the tube during the winding of the spun yarn.
  • the tubes frusto-conical tubes of plastics or any other material
  • the tubes used for supporting the yarn wound during spinning must be mounted rapidly on the bare spindle in a secure position as they have to allow spun yarn deposition without the minimum vibration and without allowing any even slight relative movement between them and the connected spindles, such that their axes of rotation perfectly coincide during the entire deposition of the wound yarn.
  • centering elements which are suitably fixed on the spindle for centering and locking the tube thereon, are therefore excessively difficult to produce. Mainly because of this it is not always possible to justify the production cost for the results obtained.
  • These known centering elements are also available in the form of balls and helical springs which cause the balls to rest elastically against the inner surface of the mounted tube.
  • the tube can certainly be satisfactorily fixed radially and axially with these devices, it is always possible for the axial and radial position of the tube on the spindle not to be perfectly maintained because of yielding of the fixing means used.
  • the present invention provides a spinning spindle which with simple low-cost construction provides reliable fixing of the tube while at the same time achieving a connection providing perfect centering in both a radial and axial direction between the two components. All this results in various advantages in terms of the construction and assembly of the spindles as the element for locking the tube on the spindle allows extremely simple and extremely precise mounting and withdrawal of the tube at each spinning cycle.
  • a centering and locking element for fixing the tube onto a spinning spindle of a ring-spinning machine, wherein said element consists of a simple filiform elastic element of steel, preferably harmonic steel, housed and supported in a thin annular groove formed in proximity to the upper end of the spindle, said elastic locking element having a substantially polygonal geometrical shape in the form of a ring which is sufficiently open to allow circumferential elastic deformation of its projections.
  • said polygonal elastic locking element Before its elastic deformation, said polygonal elastic locking element has an inscribed inner circle of diameter greater than the diameter of the base of the annular groove, whereas after its elastic deformation, with the tube locked on the spindle, its inscribed inner circle presses against said base diameter of the thin annular ring, its configuration still being open-ring, ie with its ends not touching each other.
  • the polygonal elastic locking element has a right cross-section of substantially circular profile.
  • the elastic locking ring is in the shape of a polygon with at least three projections or vertices, which are advantageously rounded for accurate centering between the spindle and tube, said projections being distributed substantially equidistant along the circumscribed circumference of said polygon.
  • 1 is the vertically extending spinning spindle well known to the expert of the art
  • 2 is the axis of rotation of the spinning spindle of the ring-spinning machine
  • 3 is a thin annular groove formed in proximity to the upper end of the spindle 1
  • 4 are the axes of the three advantageously rounded projections of the elastic polygonal element 9 according to the present invention.
  • Said projections or vertices 12 represent the locking portions for the tube 10 when mounted about the spindle 1;
  • 5 is the already known centering prong extendable within a radial cavity under the action of a helical spring, this prong, of which usually three are provided, representing the known application in spinning spindles;
  • 6 are the ends of the open-ring elastic element 9. Said ends 6 never make contact with each other;
  • 7 is the inner circle inscribed within the polygon of the elastic element 9, said circle 7 having a diameter greater than the base diameter 8 of the thin annular groove 3 before the tube 10 is mounted;
  • ⁇ is the rotation undergone by the axes 4 of the projections 12 by the end of elastic deformation of the element 9, ie when the tube 10 mounted about the spinning spindle 1 is locked.
  • the polygonal elastic element 9 is inserted into the thin annular groove 3 by using the known pliers used for split rings.
  • SEEGER Said elastic element 9 surrounds the base diameter of the groove 3 with sufficient clearance; in this respect its inscribed circle 7 is of greater diameter than the diameter 8 such that when it rests against the side of the groove 3 its rounded projections 12 extend outwards beyond the diameter of the spindle 1; whereas when in its open ring form its ends 6 are spaced substantially apart (see Figure 3).
  • the tube 10 is gripped for mounting about the spindle 1.
  • the tube 10, on which the wound spun yarn is to be deposited is of frusto-conical shape both inside and outside and is mounted via the larger-diameter end.
