Definitions

  • the present invention relates to a winding machine and is directed, more particularly, to a winding machine incorporating improved traversing mechanism for directing a strand of yarn onto a takeup package, especially at very high speeds, i.e., in the order of 5,000-6,000 y.p.m. and higher.
  • yarn is used in the general sense to apply to all kinds of strand material either textile or otherwise, and the designation package" is intended to mean the product of a winding machine, whatever its form.
  • a winding machine incorporating traversing mechanism comprising a plurality of traversing guides or fingers connected to oppositely moving endless members such as belts, tapes, chains, etc., for traversing the yarn to-and-fro axially of a package core to thus wind the yarn into-a package on the core.
  • the endless members move in opposite rectilinear paths and, at each end of the package, reversal of the yarn is effected by transferring the yarn from a first one of the yarn fingers moving in one direction to a second of the yarn fingers moving in an opposite direction relative to the package core axis.
  • the yarn is constrained to move in a path parallel to the package axis as it is traversed to-and-fro by the yam-engaging fingers on the oppositely moving endless members. Consequently, as the yarn is moved from one end of the package to the other, engaged on a given yarn finger, the yarn slides outwardly-relative to said finger and finally drops off over the tip of the finger proximate to one end of the package.
  • an oncoming finger in a companion endless member moving in anopposite sense picks the yarn up to move it toward the opposite package end, the yarn again progressively sliding outwardly of said finger to a point corresponding to said opposite end of the package where it ultimately drops off the finger for engagement by another oppositely moving fin'ger.
  • Winding machine incorporating traverse mechanisms having crossed belt spans such as those just referred to have proven to be successful and efficient mechanisms for traversing yarn onto a takeup core at high speeds.
  • the supporting mechanism including the guiding pulleys, sprockets, etc., and other structures which operate to guide the oppositely moving belt spans in the aforedescribed crisscross paths must be constructed in a rather complex manner to direct the spans properly while, at the same time, providing stability to the spans as the move their yam-engaging fingers along to traverse the yarn axially of the package.
  • the present invention represents improvement upon the traversing mechanism such as those just described.
  • means are provided for guiding oppositely moving belt spans in paths which are substantially rectilinear and generally parallel to the axis of the package core and the spindle upon which the core is mounted.
  • each belt span carries one or more yarnengaging finger, the oppositely moving fingers operating alternately to engage an advancing strand of yarn and move it axially to-and-fro of the package core to thus build a yarn package.
  • Means in the form of yarn-guiding members having surfaces which engage the yarn as it is moved to-and-fro by the yarn-engaging fingers are provided. These members act to manipulate the path of the advancing yarn cooperatively with movement of the yarn by the fingers.
  • the members function to continuously alter the vertical path of movement of the yarn simultaneously with its advance to the takeup spindleand during its traversal movement by the yarntraversing fingers to thereby situate the yarn in a position for precise transfer from one yarn-engaging finger to an oppositely moving one at loci corresponding with each end of the package.
  • One of the yarn guiding members is configured to cause the yarn to move progressively outward on an active yarn engaging finger as the yarn moves axially of the package core in one direction and to cause the yarn to slide off the end of the yam-engaging finger as the yarn reaches one end of the package whereupon the yarn is instantly picked up by an oppositely moving finger to be traversed in the opposite direction.
  • a further yarn guiding member operates similarly to cause the yarn to be progressively moved off this oppositely moving finger and to be discharged therefrom at a point corresponding to the opposite end of the package for instantaneous pickup by another oppositely moving finger. These steps are repeated until a package of desired diameter is wound.
  • Another object of the present invention is to provide a traverse mechanism capable of traversing yarn at high speeds onto a core to form a package of yarn wherein the traversing mechanism includes yarn-engaging fingers mounted on a pair of oppositely moving belt spans which are movable through a yarn traversing zone in paths parallel to the axis of the core for traversing the yarn.
  • Still another object of the present invention is to provide a traversing mechanism for traversing yarn axially of arotating c0re to wind a package and for controlling the point of reversal of the yarn at each end of the package with precision to thereby form a package having rigid, parallel end walls.
  • another object of the present invention is to provide a yam-traversing mechanism which includes a pair of oppositely moving belt spans adapted to travel in paths parallel to the axis of the package and its supporting spindle, said spans being provided with yarn-engaging fingers for moving the yarn axially of a package core to thereby wind the package, and said traversing mechanism further including means for displacing the yarn progressively across each yarn-engaging finger as said finger moves the yarn across the package, the yarn being ultimately displaced from engagement with the finger in a zone corresponding to an end of said package.
  • the invention accordingly comprises the apparatus possessing the construction, combination of elements, and arrangement of parts which are exemplified in the following detailed disclosure and the scope of the application of which will be indicated in the claims.
  • FIG. 1 is a fragmentary side elevational view of a conventional yarn takeup machine incorporating the novel yarntraversing mechanism of the present invention
  • FIG. 2 is generally a top plan view of the apparatus of FIG. 1 with parts broken away to show details of the traversing mechanism;
  • FIG. 3 is a top plan view of a portion of the traversing mechanism of the present invention showing details of the yam-guiding members;
  • FIG. 4 is a perspective view of the mechanism of FIG. 3 and indicating the path which the yarn assumes in various positions during its traverse across the yarn-guiding members by a yarn-engaging finger;
  • FIGS. 5 through 7 are detail views taken alonglines V-V, Vl-Vl and Vll-Vll, respectively, of FIG. 3 indicating the relationship of the yarn with the yarn traversing fingers during various stages of yarn traversal and showing the relationship of the several components during transfer of the yarn from one finger to another at each end of the package.
  • the present invention contemplates the provision of a pair of endless timing belts each of which is provided with a plurality of yarn traversing fingers.
  • the fingers are supported on their respective belt spans and project laterally therefrom.
  • the belts are carried on associated guide means such as timing pulleys which serve to track and drive the belts.
  • the belt spans move in opposite directions to thereby effect reciprocation or traversal movement of the yarn axially to-and-fro relative to a rotatable package core and its supporting spindle.
  • the belt spans are arranged to move in generally rectilinear, parallel paths which are also parallel to the axis of the package core and its supporting spindle in the yarn-traversing zone.
  • Yarn guiding members are provided across which the yarn passes during its advance form a supply to the takeup core. These guiding members are operative to vary the attitude of the yarn in the zone where the yarn is acted on by the yarn-engaging fingers. in consequence thereof, the yarn is removed from a one of the traversing finger moving the yarn in one direction axially of the package and is instantaneously engaged by an oncoming yarn finger moving in the opposite direction. As a result of repetition of these actions the yarn is traversed back and forth across the package. Further, by virtue of the fact that these traversing steps are repeated with precision, accurate reversal of the yarn at each end of the package is achieved while maintaining the peripheral contour of the package uniform.
  • FIG. 1 a portion of a winding machine of a conventional type, which may be the same as the apparatus disclosed in commonly assigned U.S. Pat. No. 2,740,589 to J.V. Keith, issued Apr. 3, 1956, modified as hereafter disclosed.

  • arm 12 is rockable to move the winding spindle l4 and yarn package P, supported thereon, away from the yarn traversing mechanism at a rate substantially equal to the rate at which the yarn builds up on the package.
  • the rotational speed of spindle 14 is controlled as a function of growth in the diameter of package P to maintain the surface speed of the package substantially constant throughout the winding cycle.
  • Spindle 14 is provided with an expansible and contractable mandrel indicated generally at 16 adapted to releasably grip a package core 18 on the spindle.
  • Means such as clamping lever (not shown) is provided for contracting and expanding the mandrel 16 when it is desired to remove a full yarn package P from the machine and replace it with an empty package core 18 prior to com mencement of the winding of a new package.
  • the winding mechanism 10 is driven by suitable means such as an electric motor (not shown) which may be mounted within the base of the machine and connected with the spindle 14 via suitable drive means such as a drive belt which has not been illustrated herein. If desired, the motor may be wound so that it has variable speed characteristics, that is to say, the speed of the motor would increase or decrease as electrical current supplied thereto is increased or decreased.
  • Control for the electrical current to the spindle driving motor may be achieved through a yarn tension device 20 which includes a,rockable arm 22 connected with a motor control circuit, all in the manner well known to those skilled in the winding machine art. All of the foregoing structure is old and well known in the art and further description thereof is not deemed necessary herein, the preceding discussion being presented in the interest of providing a clear and concise understanding of the present invention.
  • yarn Y flows in an upwardly directed path from a yarn tensioning element (not herein shown) to be engaged by traverse mechanism referenced generally by the numeral 30 which serves to traverse the yarn axially of the package core 18 to thereby wind package P.
  • traverse mechanism referenced generally by the numeral 30 which serves to traverse the yarn axially of the package core 18 to thereby wind package P.
  • yarn Y passes over the forward, straight edge 31 of a guide plate 32, said edge 30 being parallel to spindle l4 and the plate being affixed to the lower wall 33 of the traverse mechanism housing as by screws 34.
  • roller bail 38 provides a rotational surface on which package P is supported during its winding, the yarn flowing onto core 18 and packageP through the nip provided by the line contact of the roller ball 38 and package P.
  • said mechanism includes a pair of endless timing belts, one of said belts, i.e., belt 50 being displaced above companion belt 52, and both of said belts being movable at constant speeds in opposite directions as indicated by the arrows thereon in H6. 2.
  • Means for guiding and tracking the timing belts 50, 52 are constituted as a series of timing or guiding pulleys which are toothed to be compatible with the timing belts.
  • a first series of such pulleys 54, 56 58 and 60 are provided for guiding and defining the course of the upper endless belt 50.
  • a further series of four guiding pulleys are situated so as to define the course of and track the lower endless timing belt 52.
  • the series of guiding pulleys guiding the lower timing belt 52 only two of these pulleys are seen in FIG. 2, these being pulleys 62 and 64.
  • a further pair of guiding pulleys for the lower belt 52 are situated directly below pulleys 54 and 60, respectively, and are rotatably supported on the same axes 66, 68 as mount respective guide pulleys 54 and 60.
  • the forward guide pulleys 56, 58 for upper belt 50 and the pulleys 62 and 64 for lower belt 52 are mounted on independent stub shafts.
  • guide pulleys 56 and 58 are rotatable on stub shafts 70 and 72 respectively, the axes of these stub shafts are being disposed within the axial confines of package P and the axes of said two stub shafts also being disposed in a plane parallel to the axis of spindle l4 and core 18.
  • the span of belt 50 which reaches between guide pulleys 56 and 58 runs in a substantially rectilinear path which is generally parallel to the axis of spindle 14.
  • guide pulleys 62 and 64 which serve to guide and track the lower belt 52 are carried on stub shaft 74, 76, respectively.
  • stub shafts 74, 76 reside in the same parallel plane to the axis of spindle 14 as has already been referred to in locating guide pulleys S6, 58. However, the axes of stub shafts 74, 76 are offset within this plane with respect to adjacent stub shafts 70, 72, respectively. To this end and as seen in FIG. 2 stub shaft 70 is located rightwardly from stub shaft 74. At the opposite end of the traverse zone stub shaft 72 is located to the left of shaft 76. Tlhe displacement of the rotational axes of the several pulleys 56, 58 and 62, 64 as just described is not essential to the operation of the present invention. However, it has been found that such offset may contribute to smoother transfer of the yarn from one finger to another, particularly where yarn tension may be variable during winding.
  • a pair of stabilizing pulleys 80, 82 are rotatably mounted on associated spaced-apart stub shafts 84, 86 which are carried, within the housing of traverse mechanism 30v
  • the enlarged pulley 80 bridges the width between the front run 5011 of belt 50 and the rear run 50b of said belt to thereby simultaneously both engage both said rear and front runs and provide stability thereto as these elongated runs reach between pulleys S6, 58in their front span and pulleys 54, 60 in their rear span.
  • the enlarged stabilizing pulley 82 is of sufficient diameter to simultaneously engage the front and rear spans 52a, 52b, respectively of belt 52 to thereby steady this belt during its movement.
  • belts 50, 52 have mounted thereon, at spaced intervals, a pair of yam-engaging fingers 90, 92, respectively, each finger being adapted to project into channel 36. So situated each said finger operates to traverse yarn Y axially of package P from one end thereof to the other in a given direction consistent with the direction of movement imparted thereto by its mounting belt 50 or 52.
  • This means includes a channel bar 100 which extends along the front wall 102 of the housing of traverse mechanism 30, radially displaced from spindle 14, in a position somewhat above guide plate 32, and with the major portion thereof spaced from the front wall 102 as best seen in FIGS. 13.

  • the upper and lower members 108, 110 extend across the full length of the yarn traversing zone in generally parallel, spaced-apart positions, as seen in FIGS. l3.
  • an ear 114 is formed integrally therewith, these cars having a slot 116 therein to accommodate the shank of screws 106 but sufficiently small for the head of screws 106 to bear thereon as the screws are seated in the threaded holes in tabs 104.
  • At each end of upper guide member 108 there is a forwardly projecting tab 117 provided a relatively wide slot 118 which permits passage of the screws 106 therethrough to slots 116.
  • the spacing of channel bar 100 from front wall 102 of housing 30 is adjustable and this is achieved by loosing screws 106 and sliding member 100 along slots 116 until it is suitably situated.

  • This slope is at an acute angle, say, in the order of 7 over a l0 inch traversal span.
  • edge 122 slopes in the opposite sense and with the same angularity as edge 120. That is, the left-hand end of edge 122, as seen in FIGS. 2 and 3, is relatively distant from front wall 102 and belt run 52a, and inclines inwardly toward the front wall and toward belt run 52a as it extends to the right.
