Definitions

  • ABSTRACT Apparatus for winding spools with textile yarns comprising a yoke of two arms which are secured on a common shaft and which terminate in aligned spoolmounts.
  • the portion of the shaft between the mounting points of the arms acts as an elastic or torsion-bar system to permit the arms and their spool-mounts to yield to accommodate static or dynamic variations in the spool.
  • the present invention relates to the winding of textile yarns on yarn carriers and is concerned, more particularly, with the mounting of yarn-carriers on pivoting yokes to accommodate variations in static dimensions or dynamic behavior of such carriers so that they may be wound at speeds up to and including the extremely high winding-speeds now encountered.
  • Textile yarn-winding yokes typically comprise a pair of solid arms which are spaced from and parallel with each other. Each carries, at one of its ends, a flange for gripping the carrier or spool. The periphery of the spool bears against a driving roll which imparts the winding force to the spool. The yoke pivots on an axis passing directly through the ends of the arms remote from the ends carrying the flanges and spool. The textile yarn is distributed along the spool in a reciprocating motion by a yarn-guide which assures a positive traverse of the winding.
  • This yoke mounts the yarn-carriers most securely by the use of gripping flanges which engage the ends of the yarn-carrier.
  • the carrier-mounting yoke of that invention provides for a gradually yielding pressure on the yarn-carrier to accommodate the increasing diameter and weight of the winding. At the same time, a constant contact is assured between the periphery of the winding and the surface of the drive rollers so that bouncing or rebounding are not a problem at such low speeds.
  • the material forming the spool as it is continuously worked or flexed during rotation, experiences deterioration or structural breakdown in the regions in which the spool is engaged by the two flanges. This deterioration further aggravates the general imbalance of the system and the severity of the vibration or hammering upon reaching critical speeds. This phenomena is sufficient to cause rupture of the spool, if the winding operation is not stopped or the speed reduced to safe levels.
  • a further object of the invention is the provision of a yarn-carrier mount which can accommodate geometrically and dynamically imperfect yarn-carriers.
  • Another object of the invention is the provision of a yarn-carrier yoke whose arms are elastically positioned to accommodate, individually, imperfections at different locations along the yarn-carrier.
  • a still further object of the invention is the provision of a yarn-carrier yoke which mounts the carrier by means of flanges engaging the carrier-ends and which can safely wind the yarn-carriers at speeds in excess of 2,000 m/min.
  • the preferred form of the present invention comprises a biased, pivoting yoke for holding a textile yarn-carrier spool to be driven by its periphery.
  • the yoke includes a pair of arms arranged on parallel planes and each having, adjacent one of its ends, a rotatable flange for gripping the spool at its ends, with the two flanges being coaxial with each other under normal conditions.
  • the yoke further includes joining means for joining the arms in spaced substantially parallel relationship, which joining means includes elastic means flexibly responsive to variations or reactions of the spool while it is being rotated to permit an angular displacement of the two arms relative to each other.
  • phase reactions of the spool refers to the stresses that the rotating spool imposes on the flanges as a result of the spools dimensional or dynamic imperfections.
  • the relative angular displacement of the arms occurs primarily on individual planes perpendicular to the pivot axis of the yoke. This plane will be referred to hereinafter as the plane of displacement.
  • the flexing means by which the yoke is sensitive or responsive to the reactions of the spool, is arranged to permit angular displacement of at least that part of the arm which carries thespool-mounting flanges.
  • the angular displacement preferably is accomplished by means of a flexing of the two arms, which are parallel under nonnal conditions, about a common axis parallel to the pivoting axis of the yoke.
  • the flex-axis of the arms is arranged to coincide with the pivot axis of the yoke.
  • the flexing means includes an elastic linking system between the two arms and which is deformable at least in the direction which permits the arms to move in the plane of displacement.
  • FIG. 1 is a generally vertical, sectional view of the preferred form of yieldable yoke of the invention
  • FIG. 2 is a sectional view taken along lines IIII of FIG. 1;
  • FIG. 3 is a view of a fully wound spool as produced by the present invention.
  • the preferred form of the present invention includes a drive roller 1, which is driven at a constant speed and against which is pressed the yarn-winding 2 which is wound on a cardboard yarn-carrier or spool 3.
  • the textile yarn which may be of any size or composition, is fed to the spool 3 in a reciprocating motion on a plane parallel to the axis of the drive roller 1, by a cam 5 which controls a yarn-guide 6.
  • a pair of generally symmetrical arms 7 and 8 each have one of their ends rigidly secured at spaced points on a shaft 9 by any suitable means such as by clamping or by keys.
  • the arms 7 and 8 are arranged substantially parallel with each other and extend from the shaft 9 on the same radius, so that they form a U-shaped arrangement or yoke.
  • the shaft 9 is journalled at its ends, thereby forming pivots in bearings 10, 10' which are mounted on a fixed structure such as the frame members 11 and 11,' respectively.
  • the arms 7 and 8 carry aligned bearings 12 and 13, respectively, which receive stub shafts l4 and 15, respectively, for both sliding and rotational movement therein.
  • the flanges are of the type disclosed in the aforementioned US. application Ser. No. 287,080 filed Sept. 7, 1972, and are biased against the spool as taught in that application.
  • the shaft 9 In its center, the shaft 9 has a lever 16 rigidly secured thereto and extended in a direction generally opposite the radial direction of the arms 7 and 8. As best shown in FIG. 2, the lever 16 engages a cable 17 which passes over a pulley 18 to a conventional counterweight assembly 19. Although it is not necessary that the cable 17 be formed of elastic material, elastic material is preferred in order to prevent the counterweight 19 from going into a resonant motion.
  • the counterweight 19 acts through the shaft 9 and the arms 7, 8 to cause the spool 3 to be pressed or biased against the drive roller 1.
  • the amount of this bias can be regulated by changing the number of the individual weights making up the counterweight assembly 19.
  • the profile or shape of the shaft 9 is modified, in accordance with empirical study, to form two tapering, reduced-portions 9a and 9b, on opposite sides of the lever 16.
  • the shaft portions 9a and 9b then form two torsion-bars which are symmetrical with regard to the intermediate lever 16, against which the counterweight l9 acts.
  • the shaft section 9a thus acts as a torsion bar between the arm 7 and the lever 16 and the arm 8, while the shaft section 9b acts for the arm 8 to complete the flexing portion of the yoke.
  • each of the arms 7 and 8 is capable of angular displacement with regard to the other, each along its own plane of displacement. Consequently, each is capable of independent response to the reactions of the rotating spool.
  • each of the arms 7 and 8 is engaged, at its outer end, by a damper or shock-absorber such as the shock-absorber 21 shown engaging the outer end 20 of the arm 7 (FIG. 2).
  • torsion bars and 9b have been shown in their preferred, symmetrical form, it is to be understood that dimensional symmetry is not absolutely necessary. Similar results may be achieved with bars of unequal lengths and shapes.
  • gripping flanges are preferred, other spool mounts may be substituted on the arms.
  • EXAMPLE Windings such as shown in FIG. 3, were made on a winding installation equipped with a yoke having the flexing means disclosed in FIGS. 1 and 2, at a winding speed of 3,000 m/min.
  • the spools initially exhibited a false-round or eccentricity of 0.3 mm.
  • the length A" of the winding, at its base. was 370 mm and its diameter D was mm.
  • the several windings weighed between 6 and 7 kg and exhibited no false-rounds or surface irregularities.
  • the example clearly shows the advantages of the invention in making it possible to achieve textile yarnwindings at winding speeds of 2,000 m/min and more, even when using yarn-carrier tubes or spools made of cardboard or any other inexpensive material, such as plastics, composites, thin metals and the like, regardless of the fact that they are fabricated to the usual manufacturing tolerances.
  • each arm a pivot at one end of each arm, said pivots being coaxially aligned with each other, said arms each havmg yarn-carrier mounting means aligned with each other remote on said arms from said pivots,
  • bias means for biasing said arms toward the peripheral drive
