Definitions

  • This invention relates-to improvements in an automatic Winding machine and, more particularly, relates to the provision of means in an automatic winding machine for preventing the knotting of defective yarn, such as yarn having multiple ends, during the free end pick-up and tying cycle.
  • the yarn is automatically threaded through one or more servicing elements on the servicing assembly.
  • Such elements may include yarn guides, a yarn waxing attachment, mechanisms to sense the presence of supply yarn, and one or more slub catchers whose function is to mechanically inspect the supply yarn as it is wound and to exclude the passage of slubs to the package.
  • main slub catcher on an automatic winding machine may not sufiice to in spect the supply yarn at all times.
  • the fresh supply yarn may, at least for a portion of its length, escape inspection by the main slub catcher.
  • an auxiliary slub catcher on the yarn servicing section of the winding machine closely adjacent to the yarn pick-up point.
  • auxiliary slub catcher which has been so employed is that disclosed in US. Patent 3,142,451 of July 28, 1964 to Thomas E. Pitts.
  • an auxiliary slub catcher which serves to detect and remove those slubs or snarls which form in the yarn between the tension mechanism and the primary slub catcher during the pick-up and tying cycle.
  • the aforementioned slub catcher is not entirely successful when acting on multiple yarn ends. Multiple ends arise in a yarn strand when the yarn becomes doubled or looped on itself so as, in effect, to present several ends at the yarn servicing assembly and pick-up nozzle. Such condition frequently arises where, for example, the supply yarn is delivered to the yarn servicing assembly by Aug.
  • the present invention contemplates passing the supply yarn through the detecting and severing unit disclosed herein.
  • the unit includes severing means, a longitudinal slot or passage adjacent thereto, and a guide pin for manipulating the yarn the axis of the guide pin being normal to the plane of the passage.
  • the manipulating pin operates to engage the supply yarn as the yarn flows through the passage.
  • the yarn is arranged so that substantially the greatest cross-sectional dimension is situated transversely to the plane of the passage.
  • the slubs enter the passage with generally their greatest cross-section exposed for measuring by the passage, which is of predetermined width. If slubs exceeding the width of the passage are present the yarn is severed. Similarly, in the event the supply yarn has multiple ends the several ends are vertically arranged one on top of another by virtue of these strands being pulled around the pin under tension. With the several strands of yarn stacked on each other, the total cross-sectional dimension of all the yarns can be monitored as the yarns flowvthrough the passage. Normally, the width of the passage would be set to substantially the diameter of one strand of yarn.
  • the severing mechanism severs all ends upon their detection, treating the multiple ends similarly as slubs or snarls.
  • the end result, therefore, of the invention disclosed herein is a device which will perform effectively to prevent passage of the usual slubs in yarn and, additionally, will serve to prevent the passage therethrough of multiple ends as they occur.

  • FIG. 13 is an elevation view showing in detail the yarn engaging surfaces of the modified embodiment.
  • FIGS. 1 and 2 The general organization of the elements and the elements themselves illustrated in FIGS. 1 and 2 are, for the most part conventional and, therefore, these views are primarily of a diagrammatic and general nature.
  • the majority of the yarn servicing components are carried on a flat support or plate 10 constituting the cover plate of a housing 11 which en closes the various mechanisms and linkages of a conventional nature required to actuate certain of the components.
  • a flat support or plate 10 constituting the cover plate of a housing 11 which en closes the various mechanisms and linkages of a conventional nature required to actuate certain of the components.
  • such mechanisms and breakages within the housing are of a conventional nature well known to those skilled in the art, and similar to the disclosures of U.S. Patent 2,764,362, they are not shown and described herein.
  • the plate 10 and its associated housing 11 are interposed between a yarn supply source and a rotating yarn take-up package on which the yarn is wound by any conventional means while at the same time being axially traversed back and forth from end to end of the package in the usual manner.
  • the yarn as thus normally disposed during the winding operation is des ignated by the broken line Y in FIGURE 1, it being apparent that the yarn is moving in the direction of the arrow in that figure incident to its travel across plate 10 and its winding onto the package. It will be seen that the yarn Y is guided over the supporting plate 10 through an eyelet 14 fixedly positioned at the forward edge of the plate, then passed between suitable tensioning discs generally designated by the reference character 16 in FIG. 1.
  • the yarn Y extends through a usual main slub catcher designated 18, this slub catcher being conventional in form.
  • the main slub catcher 18 is adapted to intercept portions of the yarn of abnormally 4 thick diameter, or knots, snarls, or the like, and arrest their movement toward the package whereby the force exerted by the winding action will tend to part the yarn.
  • the thread may be passed through a usual waxing or wax applying device generally interposed between the tcnsioning discs 16 and the main slub catcher.
  • the wax applying device assumes the form of a wax disc W having a generally square opening through its center; the wax disc being supported on and rotatably driven by a shaft having a square end portion 30 received in its central opening, rotation being imparted to the shaft by conventional mechanism within the housing 11.
  • the thread Y extends between the rotating wax disc W and a supporting platform 31 against which the disc is urged by gravity, the arrangement being such that the disc thus rests against the yarn and due to its rotary movement is worn away evenly incident to its application to the yarn.
  • the main slub catcher 18 includes a triggering mechanism for initiating an operative yarn pick-up and tying cycle involving a yarn transfer arm 25 and an associated knotter (not shown).
  • a triggering mechanism for initiating an operative yarn pick-up and tying cycle involving a yarn transfer arm 25 and an associated knotter (not shown).
  • the free yarn end pickup and tying cycle will be initiated.
  • the break will have the free end from the supply of yarn extending between the tensioning discs 16 and the main slub catcher 18 pursued by the free end pick-up device or arm 25 in its operative movement.
  • the free end portion from supply is thus accessible to be picked up by the transfer arm 25, the free end of which moves in an arc just rearwardly of the tension discs and intersecting the generally longitudinally extending yarn Y in a direction generally transverse thereto.
  • the position of the yarn at this time may be better maintained or supplemented by the action of a suction slot 32 communicating with a main suction pipe 33 shown fragmentarily in FIG. 2, whereby the free end of the yarn is drawn into the said slot automatically.
  • This same slot serves also to clean the yarn during its passage toward the package onto which it is to be wound.
  • a suction nozzle 34 positioned to hold the free end of a reserve bobbin (not illustrated) carried by a rotary magazine in accordance with conventional practice in such manner that when its magazine is indexed to bring the reserve bobbin into operative position, the free end portion of yarn normally extending to its suction nozzle 34 will be moved into the eyelet 14 to extend across the operative parts of the transfer arm 25 to be picked up thereby and carried to the knotter in the gsual manner to replace the yarn from an exhausted bob-
  • the transfer arm 25 is exemplified as being in the form of a suction tube having one portion journaled in bearing 35 for rotation about a fixed axis spaced rearwardly of the housing 11.
  • the free end of arm 35 is swingable between the tensioning discs 16 and the usual cam plate 36 positioned to engage the follower 37 of a conventional cutter and clamp mechanism carried by the free end of the arm.
  • the cutter will be actuated by interengagernent 0f the cam plate and follower to sever the portion of the yarn carrying the slub. The latter is sucked into the slot 32 for removal through the main suction pipe, leaving the newly cut end gripped in the cutter for movement with the free end of the transfer arm.
  • the transfer arm 25 will then commence its retraction stroke through an arc generally designated by the line A in FIG. 1.
  • the yarn will be carried laterally to the righthand side of the slub catcher to a position such as at Y in FIGURE 1, and a considerable portion thereof will be caused to completely bypass the main slub catcher 18 be fore it is moved back laterally thereinto by the continued arcuate movement of the arm incident to the laying of the free end of the yarn from the source of supply into the knotter (not shown).
  • the knotter functions then to unite the supply yarn with the free end of yarn which will have been picked up previously and delivered into the knotter from the package being wound.
  • the unit 50 of this invention serves as an auxiliary slub catcher as well as a multiple end controller.
  • the instant mechanism could be readily employed as the main slub catcher of a winding machine.
  • the unit 50 of the present invention consists of a base plate 52 having an anvil portion indicated generally at 54.
  • the base plate is formed with clearance holes as at 55 which receive screws 57 therein for attachment to cover plate of housing 11 (see FIGURE 1).
  • a pair of upright ears 56, 58 integrally connected to the base plate 52 are formed with openings therein to receive a stub shaft 60.
  • the stub shaft 60 extends beyond each of the ears 56 and 58 for reception in a pair of projections 62 and 64 which extend downwardly from a bridge member 66.
  • a spring 68 is coiled around stub shaft 60 and has an end 70 engaging base plate 52 while the other end 72 engages bridge member 66 thereby urging the bridge member toward the base plate about shaft 60 as a fulcrum.
  • a tapped hole is provided which receives an adjusting screw 73 having a bearing surface 74 engaging base plate 52.
  • the head 75 of the screw has graduations engraved thereon, as at 76, which are correlated with reference mark 78 engraved on the bridge member for puposes to be made more apparent hereafter.
  • a head portion 81 which is of inverted U shape as can be best seen in FIG. 4.
  • a shaft 82 is received at its ends and extends between the generally vertically disposed legs 84 and 86 of the head portion.
  • a cutting blade 80 is rotatably received on shaft 82 and urged by means of spring 85 away from a position normal to the anvil 54.
  • a stop member 88 (FIG. 5) which acts to prevent rotation of blade 80 in the clockwise direction (as viewed in FIG. 5) beyond a vertical or normal disposition with respect to anvil 54.
  • a part of head portion 81 is a downwardly extending guide member 90 which serves to direct the yarn into the confines or passage of the cutting apparatus as defined by the anvil 54, the cutting blade '80, and the directing pin 92.
  • the latter is fixed to the anvil and extends generally vertically therefrom, its purpose being to direct multiple yarn end heneath knife blade in a manner which will be subsequently described. That side of the pin, as at 94, across which the strands of yarn are received, is flattened for improved reception of the thread thereon.
  • the height of the blade 80 above the anvil 54 is altered by means of adjusting screw 73.
  • the screw head 75 is distinct from the threaded portion 77 and has a blind hole formed therein which receives the uppermost part of element 77.
  • screw 73 is rotated until blade 80 just touches anvil 54.
  • Set screw 79 is then loosened and head 75 is rotated so that the Zero graduation thereon is lined up with reference mark 78.
  • set screw 69 is tightened and screw 73 is rotated until the desired clearance between the blade and the anvil is achieved, as can be determined by the graduations 76 on the screw head 75.
  • the clearance between blade and anvil will always be in excess of the thickness of one strand although it has been found through experimentation that it may still be operable to remove all multiple ends if the clearance is as great as three times the diameter of the strand. This result obtains since the yarn is pulled upward in the zone or passage beneath blade 80 as the yarn is moved to the knotter (not shown) by transfer arm 25.
  • the bridge member 66 is spring biased to base plate 52 to permit adjustment of adjusting screw 73 and thereby the height of the blade 86 above anvil 54.
  • This construction also allows the head portion 81 of the bridge to be raised in order to clean the slub from the blade.
  • the stop member 88 prevents rotation of blade 80 in a clockwise direction (as viewed in FIG. 5) beyond a vertical or normal disposition with respect to anvil 52.
  • the tip end of blade 80 might be caused to bear upon the anvil 54 in a position left of center as viewed in FIGURE 5 rather than in the free swing position adjacent directing pin 92.
  • the present invention is operable to remove slub during the free end pick-up and tying cycle. Accordingly, it will be apparent that substantially all of the free end portion will, as an incident to the lateral component of movement of the transfer arm be carried into and drawn into the unit 50. Moreover, pin 92 advantageously induces slubs flowing through the passage beneath blade 80 to stand upright. That is to say, the greatest cross-sectional dimension of the slub is oriented transversely to the passage between the lower edge of blade 80 and the top of anvil 54. Hence, a high degree of reliability is obtained with the instant invention in detecting and controlling slubs in yarn since these slubs enter the passage at the lower end of blade 80 in substantially their upright position.
  • transfer arm 25 draws the pair of strands down against guide member 90 which directs the yarn into the jaws of the cutting passage which have been previously described as being defined by anvil 54, cutting blade 80, and directing pin 92.
  • guide member 90 which directs the yarn into the jaws of the cutting passage which have been previously described as being defined by anvil 54, cutting blade 80, and directing pin 92.
  • the passage is positioned generally at the level of the interface between tension discs 16.
  • the tension on the yarn causes the strands to slide across the anvil plate 54, thence into engagement with pin 92 such that the strands are caused to become vertically disposed, one to the other, as illustrated in FIGURE 8.
  • the flattened portion 94 of the directing pin enables the strands of yarn to ride up into vertical disposition more easily, retaining them in that disposition during the cutting process. In this vertical disposition, the greatest total crosssectional dimension of the several strands is seen to be transverse to the yarn passage of unit 50.
  • the yarn is drawn in the direction of the arrows, as seen in FIGS. 6 and 7.
  • the uppermost strand Y moves into contact with the cutting blade 80, which by the friction induced between the blade and the strand, is drawn down about its pivot or shaft 82 into engagement with the strand, severing it. Because of the close proximity of strand Y" to Y the frictional forces induced between them are sufficient to cause breakage of Y" as well, thereby removing the multiple ends before they have travelled to the knotting mechanism. The severed ends of strands Y and Y" which have been engaged by transfer arm 25 will be drawn into the suction nozzle formed at the free end thereof.
  • the yarn directing pin may have a variety of shapes other than that already described. No attempt will be made to illustrate and describe all possible variations along these lines as most of them will be more or less apparent to those skilled in the art. There is shown, however, in FIG. 9 for purposes of illustarating the general directions in which'these variations may proceed, a modification of more than routine interest.
  • yarn directing pin 92' is illustrated as being cha-mfered so as to taper or bevel inwardly as the pin extends upwardly.
  • FIGS. 10 to 13 wherein it is generally referenced by numeral 100.
  • the modified auxiliary slub catcher consists of a base plate 102 having an anvil portion indicated at 104.
  • Base plate 102 is formed with clearance holes 106 which, like the plate 52, receive screws therein for attachment to cover plate 10 of housing 11 (see FIG. 1).
  • a pair of upright ears 108, 110, bent upwards from the base plate 102, are formed with openings therein to receive a stub shaft 112.
  • the stub shaft 112 extends beyond each of the ears 108 and 110 for reception in a. pair of projections 114 which extend downwardly from a bridge member 116.
  • a torsion spring 118 is coiled around stub shaft 112 and has one end engaging base plate 102 while the other end engages bridge member 116 thereby urging the bridge member toward the base plate about shaft 112 as a fulcrum.
  • a tapped hole is provided which receives an adjusting screw 120 having a bearing surface engaging base plate 102 in a manner similar to the earlier embodiment described above.
  • the head of the screw 120 has a flared skirt 124 with graduations engraved thereon which are correlated with reference mark 126 engaged on the bridge member.
  • a head portion 128 is formed at the end of bridge member 116 opposite the hinged portion. Said portion 128 is of inverted U shape as can best be seen in FIG. 11.
