Definitions

  • the present invention relates to spinning and twisting spindles.
  • the requirement of the textile industry for ever larger bobbins in diameter and length and for further increase in the spindle speed, cannot be met by the heretofore known spindle constructions.
  • Rotating spindle parts and the bodies protruding from the spindle for receiving bearings and devices to cushion or damp oscillations have assumed weights and dimensons which are in misrelationship to the obtained effect, viz to the wound-up quantity of yarn.
  • the forces for driving the spindles, particularly when starting and braking are, therefore, correspondingly high.
  • Still another object of the present invention consists in the provision of a spindle as set forth in the preceding pargraphs which will result in a better centering even at high driving pressure and strong thread pull.
  • a further object of the present invention consists in the provision of a spinning and twisting spindle which will be less sensitive to oscillations, especially when subjectedto overload or frequently changing thread tension.
  • FIG. 1 diagrammatically illustrates a longitudinal section through a spindle according to the present invention
  • FIG. 2 is a section similar to that of FIGURE l but illustrating a modication thereover;
  • FIG. 3 represents a longitudinal section through a spinning and twisting spindle according to the invention which has proved particularly successful in practice
  • FIG. 4 shows a section through a different sleeve receiving member
  • FIG. 5 is a section through a further modification of a spindle according to the present invention as applied to a pot spindle.
  • the spinning or twisting spindle according to the present invention is characterized primarily in that the bobbinsetting body rotates about a bearing housing which comprises two coaXially arranged sections connected at their lower ends, one section of which from the lower end thereof is movable in the manner of a supporting pendulum and at its upper end receives a guiding bearing for the rotating spindle parts, whereas the other section is entirely nonmovable and is connected to the spindle rail which supports members between the two sections for damping or absorbing oscillations and also supports the lower guiding bearing for the rotating spindle parts.
  • a bearing housing which comprises two coaXially arranged sections connected at their lower ends, one section of which from the lower end thereof is movable in the manner of a supporting pendulum and at its upper end receives a guiding bearing for the rotating spindle parts, whereas the other section is entirely nonmovable and is connected to the spindle rail which supports members between the two sections for damping or absorbing oscillations and also supports the lower guiding bearing for
  • the lower tubular section 2 has inserted thereinto a rod 6 which is reduced in thickness at 7 so that it can carry out a pendulum movement.
  • this machined portion may in cross-section be of a hyperbola shape and may be located in the central plane of the lower bearing 8 or Whorl 9. The pendulum movement takes place about the narrowest portion and amounts to a fraction of 1 millimeter.
  • FIG. 2 the latter likewise shows a spindle rail 1 having threaded thereinto a tubular section 2 by means of a thread 4 and secured to said spindle rail 1 by means of a nut 5.
  • the difference between the embodiment of FIGS. 1 and 2 consists primarily in that the rod 6a is firmly inserted in the tubular section 2a and that the tubular extension 3a which is connected to the tubular section 2a by means of a resilient connection 7a is adapted to carry out a pendulum movement. All other portions of FIG. 2 substantially correspond in structure and operation to those of FIG. l with the exception that the upper bearing 11 of FIG. 2 is mounted in the tubular extension 3a and is able, similar to FIG.
  • FIG. 2 illustrates the possibility of employing the creeling body directly as yarn sleeve thereby further reducing the rotating masses.
  • the yarn body 17 is thus wound directly upon the creeling body 9, 10.
  • FIG. 3 shows a spindle rail 21 supporting a tubular body 22 through the intervention of a threaded sleeve 23 and is secured to said spindle rail 21 by means of a washer 24 and a nut 25.
  • a pendulum rod 26 which within the area of the whorl 39 is journalled in the manner of a joint and more specifically, by the fact that the pendulum rod has its lower end designed as a flexible pipe 27 with a helical slot 28.
  • the axial support is furthermore effected by the stepped studs 29, 30
  • the upper end of the pendulum rod 26 has a hollow chamber 32 which forms a bearing and lubricating chamber.
  • an antifriction bearing 33 with a short spindle shank 34 rnay be arranged in said hollow chamber as oil feeding means, or an antifriction bearing 33 with a short spindle shank 34 and a thrust bearing 35 (see FIG. 4) may, similar to a normal spindle bearing, be arranged in said hollow chamber 32.
  • the bobbin carrier is designed as a cylindrical pipe 36 and at its upper end has a supporting body 37 while its lower end has a supporting body 38.
  • the supporting body 38 may at the same time have the whorl 39 connected thereto as an integral part.
  • the bobbin carrier is by means of a pendulum bearing 40 supported along the radial central plane of the whorl 39.
  • the bearing 40 may be protected against loss of lubricant, etc. by a seal 41.
  • Any desired braking device as, for instance, a magnetic coupling 42, may be employed for stopping the spindle.
  • the pendulum rod 26 is able to carry out all necessary pendulum movements in conformity with the pendulum movement of the bobbin carrier. These deviations from the vertical position are limited merely by the damping or cushioning devices 43 in the tubular body. Such cushioning devices may, for instance, be represented by a spiral spring with oil. In view of the length and the diameter of the tubular body, the cushioning devices may from the top toward the bottom correspond to the increase of the yarn body or the changing of the center of gravity. In this connection, the cushioning devices may be all alike or may be different and may be subdivided in steps as indicated by the reference numerals 34a, 34b and 34C.
  • An elastic sleeve 44 hermetically seals the cushioning chamber or chambers toward the top so that no changes in the damping effect will be possible by a change in the viscosity of the Oil Q15 by foreign bodies such as fibers,
  • FIG. 4 differs from that of FIG. 1 primarily in that the long creeling body 36 of FIG. l has been replaced by two separate short creeling bodies 47, 48 respectively which are each separately journalled at the upper and lower portion of the spindle.
  • a special electric motor may be provided with a disc stator 51 and a superimposed disc rotor 52.
  • the advantage of this design is the low structural height and the possibility to employ the disc stator 51 or the housing 51 thereof as support 53 for the tubular body, whereas the disc motor rotor 52 is inserted into the creeling body 48 and therefore does not require a bearing of its own.
  • the rotor as well as the stator are protected toward the outside by a cap 54 forming a part of the creeling body 48.
  • FIG. 5 shows the employment of a spinning or twistmg spindle according to the invention with a pot.
  • the arrangement of FIG. 5 has also a bobbin carrier body 55, a pot 56, a bottom 57, a conecting member 58, a receiving cone a pot cover 60, and a bobbin pipe 61 and yarn body
  • the heretofore designed pot spindles have rather critical running properties because in view of the withdrawal of the thread, the center of gravity is continuously changed.
  • the new bearing arrangement with its damping or cushioning devices subdivided over the entire length makes it possible over heretofore known spindles to function and also to increase the spindle speed.
  • rod 6 is fixed, and the tubular extension 10 carries out its pendulum movement through the cushioning means 13a, 13b, 13C. This is made possible by the elastic sleeve 7a interconnecting the members 2a and 3a. The outer movement of whorl 9 and extension 10 is likewise made possible by the play of the roller bearing 8.
  • the spinning and twisting spindle according to the invention as described above makes it possible to a far better extent than could heretofore have been realized to solve all spindle dimensions and problems associated therewith.
  • the said spindle parts may have thin walls and will therefore be of low weight.
  • the weight of the bobbin creeling body may be even further reduced by subdividing said body into two sections journalled separately and the connection of said body sections may be effected only by the yarn sleeve.
  • the bobbin creeling body itself may function as yarn sleeve or yarn receiving body.
  • the driving pressure acts directly upon the lower bearing which to a majorl extent is mounted within the area of the central plane of the drive or whorl and therefore does not affect the centering of the upper portion of the spindle.
  • the centering is anyhow considerably better with heretofore customary spindles because the centering means are arranged where the thread pull acts most strongly upon the spindle.
  • a spinning and twisting spindle which includes: tubular means having a lower end portion for fixed connection to a spindle rail and also having an upper end portion, bobbin receiving means surrounding said tubular means in radially spaced relationship thereto and extending in the longitudinal direction of said tubular means, first and second bearing means spaced from each other in the axial direction of said bobbin receiving means and respectively located near said upper and lower end portions of said tubular means for rotatably journalling said bobbin receiving means relative to said tubular means, and cushioning means interposed between said first and second bearing means for absorbing oscillations of said bobbin receiving means.
  • a spindle according to claim 1 which includes: whorl means forming the lower part of said bobbin receiving means, and in which said bearing means near the lower end portion of said tubular means is designed as pendulum bearings, said pendulum bearing being located in the area of the radial central transverse plane of said who'rl means.
  • a spindle according to claim 1 which includes: a who ⁇ rl near the lower portion of said tubular means, and in which said tubular means is supported for a limited pendulum movement near the central horizontal plane of said whorl.
  • a spindle according to claim 1 which includes: lubricant containing chamber means adjacent said cushioning means.
  • a spindle according to claim 1 in which said bobbin receiving means comprises two sections journalled separately and individually and in which sleeve means are provided interconnecting said last-mentioned two sections.
