Definitions

  • the present invention relates to a winding machine and is directed more particularly to an improved traversing mechanism for controlling the path of movement of yarn or similar strandular material while winding the material at high speeds onto a take-up unit.
  • 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 variety of techniques have been proposed for traversing yarn at high speeds axially back and forth on a package core.
  • use of reciprocating or oscillating yarn engaging members carried on complementary, independently controlled, rotatable wheels, belts, chains or the like have been disclosed for traversing yarns.
  • the yarn is traversed axially of a rotating package core in one direction by one of the independent members and is thereupon intercepted by the complementary, separately controlled member moving in the opposite direction. In consequence thereof, the yarn is shifted back to the opposite end of the package. This to and fro motion of the yarn results, of course, in its being traversed onto the supporting core to form a yarn package.
  • the present invention provides a traverse mechanism for a winding machine wherein the yarn may be advanced at high speeds, in the order of 4,000 yards per minute and higher, while the yarn is traversed onto a core and reversed at the ends of the package in a positive manner thereby winding a cylindrical yarn package having highly acceptable configuration and characteristics for further use.
  • One object of the present invention is to provide a yarn traversing mechanism suitable for operation at high speeds.
  • a further object of the resent invention is to provide a traverse mechanism capable of traversing yarns at high speeds without the use of reciprocating parts.
  • a further object of the present invention is to provide a traversing mechanism for traversing yarn axially of a package and for controlling the point of reversal of the yarn by positive means to thereby wind a package having parallel side walls devoid of stitches, ridges and other imperfections.
  • a further object of the present invention is to provide a traversing mechanism which is economical to manufacture, and yet highly reliable in use.
  • 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 front elevational view of a winding machine incorporating the improved yarn traversing mechanism of the present invention
  • FIG. 2 is a top plan view of the apparatus of FIG. 1;
  • FIGS. 3, 4 and 5 are enlarged fragmentary front elevational views of the left-hand end of the yarn traversing mechanism, illustrating various steps as the yarn is reversed in its direction of movement;
  • FIGS. 3a, 4a and 5a are top plan views of the structures of FIGS. 3, 4 and 5 respectively.
  • the present invention contemplates the provision of an endless belt provided with a plurality of yarn traversing pins.
  • the pins are embedded or otherwise supported along the side of the belt and extend laterally therefrom.
  • the belt is carried on guide pllleys which serve to track and drive the belt.
  • the pulleys direct the belt in a path so that it provides upper and lower generally horizontal belt runs or spans extending the length of a rotatable yarn package core.
  • the upper and lower spans of the belt are disposed in horizontal planes parallel to each other. However, in the vertical plane these oppposing spans are offset from alignment with one another. That is to say, the upper span of the belt is angled or offset in one direction and the opposing or lower span of the belt is offset in the opposite direction.
  • the upper and lower belt spans present a criss-cross or substantially X-shaped pattern, the midpoints of the two spans intersecting in the plane of the midpoint of the package core.
  • Camming fingers are provided adjacent each end of the package core. These fingers are operable to receive the yarn from the traversing pins at each end of the package. Furthermore, the fingers act to damp vibrations in the yarn caused as the yarn is relieved from engagement with its traversing pin. With these vibrations controlled, the yarn will be suitably positioned for interception by a further traversing pin.
  • an advancing strand of yarn being delivered to the package core from a fixed fanning point remote from the support is engaged, for example, by a yarn traversing pin in the upper span of the belt and carried from left to right of the package core to traverse yarn thereon.
  • a yarn traversing pin in the upper span of the belt At the right-hand end of the package the yarn momentarily contacts one of the fingers.
  • a further pin in the lower span of the belt engages the yarn to traverse it in the reverse direction to the lefthand end of the package and engage it against a further finger.
  • the belts are angled with respect to each other causing the particular pin which traverses the yarn at any given interval to move in a horizontal path from a position relatively close to the periphery of the package progressively outward to a position further removed from said package, and in light of the fact that the yarn is being delivered from a fixed fanning point and traversed onto a package core in a straight-line path, the yarn tends to slide outwardly to the outer end of its yarn delivery pin as the yarn is traversed axially of the package core. This facilitates removal of the yarn from each yarn traversing pin by the fingers at the appropriate instant. Furthermore, the normal straight-line path of the yarn is not interfered with to any significant degree during such action.
  • a winding spindle is shown as supported for rotation in a bearing 11 positioned in the winding head 12 of a winding machine 13 of the type, for example, disclosed in US. Patent 2,740,590 issued Apr. 3, 1956, to J. V. Keith.
  • Said bail is rotatably mounted in bearings 15 attached to a stiff support plate 16.
  • a fixed yarn guide 17 also constitutes a part of the machine and is arranged in alignment with the axial midpoint of a package core C carried on spindle 10.
  • Spindle 10 may be arranged in any convenient manner to mount the package core C thereon whereby the core will rotate with the spindle 10 to permit winding of a yarn package P thereon and such that the package and core can 'be removed at the completion of the winding cycle.
  • the machine 13 provides a mount for an angular member 18 extending from the side thereof.
  • member 18 has the elongated plate 16 securely affixed thereto as by bolts 19.
  • Plate 16 extends from the side of machine 13 generally rearwardly of and parallel to shaft 10 and projects slightly past the outer end of said shaft.
  • a plurality of pulleys here shown to be three in number referenced as 20, 21.
  • Pulley 20 serves as the driver and is secured to a power shaft 24 which, in turn, is connected with a suitable source of power (not shown) for rotating the shaft.
  • Pulleys 21 and 22 are rotatably mounted on studs 26 and 27, respectively. Each of the studs 26, 27 is threaded at its inner end to receive a nut 28, 29, respectively thereby fixing these studs in position on plate 16.
  • the opposite or outer end of plate 16 is provided with a further series of pulleys 30, 31 and 32, each rotatably supported on a respective stud 35, 36 and 37.
  • the inner ends of each of the studs 35, 36 and 37 are threaded to receive an associated nut 38, 39 and 46 for securing the studs in positionon plate 16.
  • the several studs 26, 27, 35, 36 and 37, in addition to shaft 24 are all canted away from a plane normal to the surface of plate 16 in a manner to direct an endless belt 40 which passes around the several pulleys 20, 21, 22, 30, 31 and 32 in a skewed path.
  • the belt moves in a path deviating from a straight line parallel to shaft 10. It will be observed in FIG.
  • belt 40 is disposed in the zone between shaft 10 and plate 16.
  • the belt is driven in a clockwise direction, i.e., in the directions of the arrows, its upper span is delivered ofi pulley 32 from a somewhat forward position, i.c., relatively closer to shaft 10 than to plate 16, and follows a slightly rearward path angling toward plate 16 as it moves from a position proximate one end of core C to the other.
  • the belt is then lead about pulleys 22 and 20 in a fashion to be once again shifted forwardly to essentially the forward position on pulley 26 corresponding to that from which it was delivered off pulley 32.
  • the lower span of belt 49 is then moved to the left (FIG.
  • belt 40 may be a timing belt, if desired, in which event the pulleys would be provided with grooves to mate with the teeth of the belt, all in the manner well known in the art.
  • Belt 40 is provided with a plurality of yarn traversing pegs or pins 42 of uniform length which are embedded in the side or edge of the belt. These pins are spaced apart along the belt, the spacing being a distance generally equal to twice the length of the package to be wound. As best seen in FIG. 2 these pins are bent slightly rearwardly so that the outer end of each pin 42 is in a trailing position to the remainder of the pin as the belt 40 moves clockwise in FIGS. 1 and 2. As will be more fully explained hereafter, these pins cooperate to traverse the yarn onto core C.
  • a horizontal bracket 44 is fastened to plate 16 and, as seen in FIGS. 1 and 2, resides in radial alignment with package core C.
  • a pair of fingers 45, 46 having inclined sides serving as cam edges 47, 48 respectively, are affixed to the top of bracket 44 by screws 49, 50.
  • the fingers 46, 48 are adjustable longitudinally of bracket 44 by virtue of elongated slots in the fingers through which the screws 49, 50 pass.
  • fingers 45, 46 are located at opposite ends of core C and their edges 47, 48 cooperate with pins 42 to displace the yarn from one pin and transfer it to a further pin, all to effectuate reversal of the traversing direction of the yarn.
  • pins 42 As is best seen in FIG.
  • auxiliary tracking pulleys 52, 54 are affixed rotatably on studs 56, 58 respectively, which depend from an associated one of a pair of spaced blocks 60, 62 welded to plate 16. Pulleys 52, 54 aid in tracking belt 40 during its course of movement.
  • the apparatus is .threaded up by drawing a strand of yarn Y from a suitable supply source, through yarn guide 17, and attaching it to core C in a conventional manner.
  • Fingers 45, 46 are adjusted to positions at opposite sides of core C such that they will engage the yarn at the respective package ends to remove the yarn from any one of the yarn traversing pins.
  • the yarn will contact the fingers while it is still engaged by any one of the pins.
  • the yarn will simply slide off the pin and up the inclined edge of the related finger to allow the pin to pass. It is important to note, however, that the yarn will not slide along the edge so as to be out of alignment with the oncoming pin which will convey the yarn in the opposite direction.
  • FIGS. 3-5a are illustrative of the action of the elements of the invention in effecting reversal of the yarn at the lefthand end of the package (viewing FIGS. 1 and 2). It will be appreciated that reversal of the yarn would be effected similarly at the opposite end of the package.
  • the yarn Y is seen to be engaged by one of the pins 42. It will be observed further from FIG. 3a that the yarn is riding on the bent or trailing portion of the pin.
  • the length of the pins is carefully controlled consistent with the angularity of the belt 40 and in keeping with the slope of the cams 47, 48 whereby as the yarn moves across the core C and package P it gradually migrates laterally of the pin toward the outer end thereof so that the yarn is adjacent the outer end of the pin just prior to engagement by one of the cam edges 47, 48, having moved to that outer end position from an initial or beginning position somewhat closer to belt 40 (see FIG. 512).
  • FIGS. 4 and 4a illustrate the yarn shortly after it has been disengaged from one in and just prior to its being picked up by a further pin.
  • the yarn is very briefly relieved of control by any of the pins 42 it migrates from either end of the package inwardly at a speed proportionate to the angle of deflection of yarn from its normal path in alignment with the axial midpoint of the package. Therefore, if a more rapid return of the yarn is desired the fanning point, i.e., yarn guide 17, would be moved closer to package P.
  • roller bail 14 which acts to smooth the package surface.
  • the instant invention provides means for traversing yarn axially of a core to wind a package, such traverse being capable of operation of high speeds, i.e., in the order of 4000 yards per minute and higher, while winding a package having straight, uniform side walls and providing uniformity in the circumference of the package.
  • the unique arrangement of the present invention causes the yarn being carried across the package by an active traversing pin to be deposited inwardly on the cam edge of the particular finger 45, 46 against which the yarn is moved.
  • the next pin which will convey the yarn in the opposite direction approaches the yarn from a position quite forwardly of the finger (see FIG. 4a).
  • Apparatus for winding yarn comprising:
  • Apparatus as set forth in claim 1 including guide means located between a supply source and said package, said guide means acting to direct the yarn advancing to said package in the path of movement of said traversing elements.
  • said traversing elements are elongated members, each having a yarn guiding surface, the yarn being slidable on said surface toward the outer end of the active traversing element on said first span as said first span moves toward its second position, and the yarn being slidable on said surface toward the outer end of the active traversing element on said second span as said second span moves toward its second position.
  • each said traversing element includes an inclined portion of said outer end thereof for facilitating movement of the yarn off each said element.
