Definitions

  • the present invention relates to a thread-storing device for temporarily storing a thread supplied to a textile machine, particularly a knitting machine.
  • This type of thread-storing device is also known as a furnishing wheel, ornot," and serves the purpose of supplying to a knitting machine a thread which is neither too loose nor highly tensioned, so that the knitted fabric is produced by thread supplied to the needles at constant tension.
  • the takeoff device of the knitting machine would be used without a thread-storing device for supplying the needle with thread from a wound package, the supplied thread would be subject to sudden contractions and expansions which would detrimentally affect the knitted fabric.
  • the thread is supplied between two loosely meshing gears, one of which is driven so that the thread is transported at a uniform speed.
  • This type of thread-storing device is unsuitable for knitting machines in which the length and speed of the required thread varies substantially.
  • one or the other thread may not be used at all for a while, so that supply of this thread must be stopped.
  • a thread-storing device which supplies a constant length of thread per time unit, is not suitable for machines of the Jacquard type, for example. 7
  • Another thread-storing device which takes a predetermined amount of thread from a thread package, and winds the same up so that the thread can then be supplied from the wound-up coil to the knitting machine. When the entire wound-up coil is used up, the same amount of thread is again wound up and stored.
  • This thread-storing device according to the prior art has disadvantages, inasmuch as loops or turns of the wound-up thread are pushed downward by a slide, which sometimes causes superimposing of loops, particularly if the winding drum is almost full with thread. The incorrect position of the thread on the windup drum causes jerky feeding, and furthermore due to the elasticity of the thread, sudden contractions and expansions of the thread, which detrimentally influence the quality of the knitted fabric.
  • Another disadvantage of this device resides in that a piece of the thread between the winding drum and a brake of the takeoff means of the knitting machine, is twisted when momentarily no thread is taken off, but while the winding drum rotates to wind up an additional length of thread. The respective thread portion is then twisted corresponding to the number of loops wound on the winding drum. The twisted thread causes rapid contractions and expansions of the thread, and an uneven stitch pattern of the knitted fabric.
  • Another object of the invention is to provide a thread-storing device in which the thread wound up on a holder engages the holder with low friction.
  • Another object of the invention is to provide a thread storing device in which thread is simultaneously stored on a holder in the form of a coil receiving new loops at one end, and supplying thread from the other end thereof to a textile machine.
  • the holder on which a rotary thread guide builds up a coil includes substantially parallel cylindrical rolls which are driven in such a manner that alternate rolls rotate, or angularly oscillate, in opposite directions.
  • a helical coil of thread is wound up on the rollers, and the number of loops depends on the relative speed at which the thread is wound up, and taken off, respectively.
  • the holder on which the thread is wound consists of angularly moving rollers
  • the friction between the wound-up thread and the surface of the rollers is low, so that the loops can be laid side by side, and slide on the rollers without requiring mechanical slides for pushing the windings in one direction in order to make room for the next wound loop. Consequently, the invention permits the winding of a coil by laying successive loops at the same end of the holder by which the preceding loops are pushed in one axial direction and form a completely uniformly wound coil.
  • a motor drives, preferably rotates, the rollers of the holder, and has a central shaft for driving a thread guide to rotate about the holder for laying loops on the same.
  • One embodiment of the invention comprises a holder having a main axis and including supporting means, and at least a pair of two holding members mounted on the supporting means for angular, preferably rotary, movement in opposite directions about two axes equally spaced from the main axis and being parallel to the same; drive means preferably including a motor and transmission means for rotating the holding members, which are preferably cylindrical rollers; winding means preferably a rotary member having a peripheral thread guide rotatable about the main axis for winding a supplied thread about the ends of the tubular rollers so that wound loops slide on the rollers in one axial direction from one end to the other end of each roller; and takeoff means operated by the textile machine for unwinding the leading loop from the rotating rollers.

  • the space between the tubular rollers 16 and the shaft 36 may be lubricated. While in the illustrated embodiment, the tubular rollers have substantially cylindrical surfaces, the outer surfaces of rollers 16 may be slightly conical, and tapering at an angle of 1 to 1.5". It is also possible to slant shafts 36 slightly inward in radial direction toward shaft 12.
  • a gear 50 is secured to the upper end of each roller 16 and located within the housing 14.
  • Gears 50 may consist of metal or a synthetic plastic material, and may be pressed onto rollers 16, or secured to the same in any other suitable manner. It is also possible to injection mold the roller 16 and the respective gear 50 integrally of a synthetic plastic material.
  • Gear 52 on motor shaft 12 which may consist of metal or a synthetic plastic material, meshes with an intermediate gear 54, which, as best seen in FIG. 2, is rotatably mounted on a journal 56 secured to the top wall 38 of transmission housing 14. Journal 56 may also be pressed into corresponding bores of top wall 38.
  • the intermediate gear 54 is held against axial downward movement by a split ring, not shown.
  • the intermediate gear 54 meshes with motor gear 52 and with one of gears 50 so that rotation of motor shaft 12 in one direction of rotation causes rotation of the respective gear 50 in the same direction.
  • the two gears 50 meshing with the respective gear 50 will rotate in the opposite direction, and the arrangement is such that alternate gears 50 will rotate in opposite directions during continuous rotation of motor shaft 12 in the same direction, Four gears 50 rotate in clockwise direction, and four other gears rotate in counterclockwise direction.

  • each tubular roller 16 is provided with a head portion 30 which has at the end an outer surface with a diameter greater than the diameter of the main portion of rollers l6, and this diameter is gradually reduced in upward direction so that the surface of the head portion 30 gradually merges into the outer surface of rollers 16.
  • the upper rim 32 of the axially projecting flange 26 of disc 22 projects a small distance, for example a few millimeters, beyond the lower circular edge 34 of rollers 16.
  • the top face 23 of disc 22 is spaced a small distance from the free ends 37 of shafts 36, so that disc 22 does not touch the shafts 36.
  • the inner surface 27 of flange 26 is spaced from the radially outermost points at the free ends of roller 16. Between the edge 34 of rollers 16 and the inner surface 27, a distance of between 2 and 3 mm. may be provided.
  • FIG. 1 shows a number of loops already laid about the eight rollers or holding members 16, the loop 58 leading in the direction in which the coil is built up.
  • a thin circular plate 60 rests on the uppermost leading loop 58, and has openings for the passage of the rollers 16 and motor shaft l2.
  • a permanent magnet 62 is mounted on plate 60, and moves with the same when the number of windings on rollers 16 increases or decreases.
  • the yarn 18 is guided from the uppermost leading loop on the eight rollers 16 about the circular peripheral rim 72 of winding disc 22, 26 to a conventional brake 70 from where it is pulled out by the knitting machine, not shown, in the direction of the arrow A.
  • FIGS. 1 and 2 operate as follows:
  • the operating textile machine will pull the thread 18 through the brake means 70 and remove the uppermost loops, starting with loop 58 and then continuing to take off successive loops in downward directionv Consequently, the height of the helical coil is continuously reduced, and plate 60 moves downward.
  • the start switch of motor 10 is closed, and the motor rotates shaft 12, for example, at a speed of l,400 r.p.m. while the rollers 16 rotate at a rotary speed of 700 rpm. due to the transmission ratio of 2: 1 between motor shaft gear 52, and gears 50.
  • the rotary speed of motor 10, and thereby the winding speed of the thread 18, are so selected that even at the fastest operations of the knitting machine, a greater length ofthread is wound up by the motor and the winding means on rollers l6, than is used by the machine and taken off the upper end of the coil.

  • any other number of pairs of rollers 16 may be used for one holder, and it is preferred to have an even number of rollers 16 in ozder to prevent transporting of wound-up loops in circumferential direction, which is prevented by adjacent rollers 16 rotating in opposite directions.
  • rollers 16 instead of rotating rollers H6, it is possible to oscillate rollers 16 in an angular movement, but as explained above, adjacent rollers must oscillate in opposite directions so that the friction of the thread on the rollers is reduced, without driving the thread in circumferential direction.
  • semicylindrical elements instead of rollers, semicylindrical elements may be used which are oscillated in opposite directions by a suitable linkage.
  • successive loops of the thread are wound by thread guide 28 onto the tapered head portion 30 of rollers 16. Due to the slant of the head portion, the thread tends to move inward, and consequently upward, so that the axial movement of the wound loops in upward direction is facilitated, and room is made for the next following wound loop.
  • the apparatus operates satisfactorily with cylindrical rollers 1l6 which are not provided with the tapered head 30, since each newly wound loop pushes the preceding loop upward.
  • rollers 16 are not tubular and mounted on shaft 36, but are solid cylindrical rollers mounted in bearings of housing means lid,

  • the motor is braked to a stop when the wound-up coil has a predetermined axial length.
  • the leading loops are successively taken off, as explained above, so that the height of the helical coil is reduced, so that fewer loops exert friction on rollers ll6 so that the motor starts again to rotate since it is capable of overcoming the reduced load.
  • More loops are then wound up by the motor than are taken off, so that the number of loops increases together with the friction so that the motor is again braked and stopped.
