Definitions

  • Another object of the present invention is a package ejecting device for a supply package indexing mechanism, which device is operable as the mechanism indexes to dislodge the package holder from the support therefor and guide the dislodged holder away from the indexing mechanism.
  • a further object of the invention is a combination with a supply package indexing mechanism of a package ejector including means for initially unseating the package holder from its support on the mechanism and means for displacing the unseated holder laterally from the support and "ice away from the indexing mechanism, both of which means are cam-actuated during the indexing operation.
  • FIG. 1 is a right side elevational view, with certain parts shown in section, of a yarn supply package indexing mechanism in association with the package ejector of the present invention, the ejector being illustrated in the act of guiding an empty package holder away from the indexing mechanism;
  • FIG. 2 is a horizontal sectional view taken substantially along line 22 of FIG. 1, looking down at the package carrier in the position assumed thereby during normal winding;
  • FIGS. 3 and 4 are enlarged detailed views taken in section substantially along lines 3-3 of FIG. 1 and 4-4 of FIG. 1, respectively.
  • the present invention may be characterized as comprising a carrier for at least two yarn holders arranged for rotation about a vertical axis and adapted for rotation from time to time through a limited are about said axis to simultaneously transfer one package initially in active position to a reserve position and the other package from reserve position to the active position, the carrier including a corresponding number of supports at points spaced circumferentially therearound and upon which the holders are seated.
  • a lift member mounted adjacent the support for each package holder is a lift member which is adapted to be raised to displace the holder from its seat on the support and disposed above each support is a discharging member which is adapted to be swung outwardly to engage the package holder and thrust it away from the package carrier.
  • Both of the lift and discharging members are provided with cam followers which, during the rotation of the carrier, are engaged by independent cams and actuated thereby.
  • the discharging member takes the form of an elongated tube surrounding each package holder over a major portion of its length when seated on a support and terminating above the upper end of the package support, the tube being pivoted for independent rocking movement in an arm rotating with the carrier.
  • the invention may also include a trough or tray for collecting the ejected holders.
  • the numeral 10 designates a part of a yarn winding machine situated at the preferably in the form of an inverted U-shaped channel having its end edges resting upon the floor or other support for the machine.
  • a shaft 14 extends between the part 10 and rail 12 and is suitably journalled therein for rotation about a vertical axis.
  • shaft 14 projects below the top wall of rail 12, as at 16, and a bevel gear 18 is rigidly fixed on the shaft end.
  • Meshing with bevel gear 18' is a bevel pinion 20 secured to the outer end Situated beneath housing 10. in the vertical spaced relationship thereto is a rail 12,
  • shaft 22 extending rearwardly toward the remainder of the winding machine (not shown), the rear wall of rail 12 being suitably cut away, as at 24, to accommodate the shaft.
  • the end of shaft 22 remote from rail 12 is connected to a suitable source of power (not shown) and it is contemplated that shaft 14 shall be rotated, from time to time, through a limited are either by periodic operation of shaft 22 or in some other manner, as desired.
  • shaft 14 may be arranged concentrically to a second shaft carrying bevel gear 18, and member may contain a clutch mechanism for coupling the upper ends of shaft 14 and the gear-carrying shaft when indexing is to take place, in accordance with the arrangement described in the aforesaid application of Pitts and Steele.
  • a yarn carrier member constructed as a spider having a central hub portion 28 press-fitted or otherwise secured on shaft 14 and two branches 30, 30 extending radially from hub 28 in diametrically opposite directions. Adjacent their respective outer ends, branches 30 and 30' carry vertically arranged posts 32, 32' having their upper ends tapered, as at 34, to receive and support yarn supply package holders. As shown in the drawings, these packages are in the form of tubular bobbins provided with an axial bore into the lower ends of which the tapered ends 34 of the posts 32., 32 fit to support the packages with their axes parallel to the axis of shaft 14. It will be understood, of course, that carrier 26 could be adapted to support other types of yarn holders as well.
  • Branches 30, 30 are provided at their inner ends adjacent hub 28 with pairs of spaced-apart upstanding ears 36, 36 which are bridged at their upper ends by horizontal pins 38, 38'. Projecting outwardly from the pairs of ears 36, 36, with their inner ends pivoted on pins 38, 38', are lift arms 40, 40 which terminate with enlarged spadelike portions 42, 42 (see FIG. 2). The latter portions are slotted, as at 44, 44, to fit around posts 32, 32', the slots being radially elongated to permit arms 40, 40 to pivot about pins 38, 38. The transverse dimension of slots 44, 44 is so selected that it just exceeds the exterior diameter of the posts.
  • Enlarged portions 42, 42 are preferably bowed upward- 1y or convexly bent from the normal plane of the arm so that, when the arms are in fully depressed position, the outer edges of the spade portions rest against the top surface of branches 30, 30 with the inner ends of the lift arms supported above that surface in the ears.
  • Fitting around posts 32, 32' between the tapered end portions 34 and enlarged portions 42, 42 of lift arms 40, 40' are tubular sleves 48, 48', which are just long enough to leave the tapered end portions exposed when lift arms 40, 40 are in fully depressed position.
  • each sleeve 48, 48' is engaged by the marginal edges of the slot in the corresponding enlarged arm pontion.
  • the sleeve associated therewith will likewise be elevated above the upper limit of the post which it surrounds to unseat the yarn holder on that post.
  • the elevation of the lift arms is accomplished through the medium of elongated tongues 50, 50', each formed integrally with a lift arm 40, 40', and depending downwardly therefrom, which tongues pass through elongated apertures provided for that purpose in the branches, as at 52.
  • a plate cam 54 situated between carrier 26 and .rail 12 and supported on a collar or pedestal 56, which may also serve as the journal for shaft 14, encircling shaft 14 and attached to the top wall of rail 12.
  • Cam 54 is stationary, being cut away at its center to clear the external surface of shaft 14, and peripheral edge 58 thereof constitutes a cam surface for tongues 50, 50. As is best shown in FIG.
  • the peripheral edge 58 of cam 54 is concentric with shaft 14 except at the rear side thereof, at which side edge 58 is extended outwardly, as at 60, to form a lobe or salient.
  • Sleeves 48, 48 are freely slidable with respect to posts 32, 32', and lift arms 40, 40' are free to rock to a considerable extent about their pivot axes. Consequently, the corresponding sleeves and arms will normally tend, due to the influence of gravity as well as the weight of the package holder, to assume a fully downwardly depressed position on the carrier arms and the radius of the concentric edge portion of cam 54 is so selected that the inner edges of tongues 50, 50 will just contact that edge.
  • the package lift arms 40, 40' and sleeves 48, 48' will remain in fully depressed position, exposing the tapered upper end portions 34 of posts 32, 32 for engagement with the package holders until the tongue of a lift arm encounters the lobe portion of cam 54.
  • the tongue will be moved outwardly away from shaft 14, causing the corresponding lift arm and sleeve to be raised on the corresponding post, and unseating the package holder on that post from the tapered post end.
  • the point on the circular path of the package holders through which the axis of lobe 60 passes may be varied, although, of course, that point must be located between the loci on the path for the active unwinding and reserve positions of the holders, since, in such each position, the posts must be capable of receiving and supporting a package.
  • One satisfactory arrangement has been found to be with the axis of lobe portion 60 extending approximately at right angles to the longitudinal axis of rail 12, i.e., approximately parallel to the axis of shaft 22, so that the holder being transferred from active position to reserve position is unseated from its supporting post at the time that holder is positioned outside the rear of rail 12.
  • the mechanism thus far described is adapted to impart translation to a carrier for yarn package holders and, during the course of such translation, to unseat one of the holders from the means by which it is supported on the carrier. It is conceivable that the mere unseating of the package holder from its support may not result in the holder actually being discharged from the carrier. For this reason, the present invention includes means for actually engaging the unseated package holder and forceably discharging it away from the carrier.
  • a hub 76 mounted on shaft 14 at a point spaced vertically a substantial distance above carrier 26 is a hub 76 formed with two integral, diametrically opposite arms 78, 78, having bifurcated end portions 79, 79', the axis of arms 78, 78' being in vertical alignment with the axis of the arms 30, 30 arranged within the bifurcated end portions of arms 78, 78 for pivotal movement about horizontal axes are collars 80, 80, one for each arm, each collar having a pair of opposed gudgeons 82 resting in upwardly facing U-shaped recesses 83 in the bifurcations.
  • Collars 80, 80 encircle and support elongated tubes 84, 84', preferably constructed of transparent plastic, or the like, which are of sufiicient internal diameter to surround a package holder carrying a full supply of yarn in spaced concentric relationship.
  • tubes 84, 84' project both above and below the level of the collars, extending over a major portion of the length of the package holders, but terminating at a level spaced above the upper limit of posts 32, 32 far enough to clear the upper ends of sleeves 48, 48' when elevated to package holder unseating position by lift arms 40, 40'.
  • collar operating levers or crank arms 86, 86' are of substantially dogleg configuration, each having a lower portion 88, 88 projecting at more or less right angles to the plane of the collars and an upper end portion 90, 90 extending angularly from the free end of lower portion 88, 88' toward the upper end of shaft 14 and terminating at a point lying on a circle concentric with shaft 14.
  • the inner ends 90, 90' of levers 86, 86' are engaged by the lower edge 92 of an annular crown cam 94, supported against rotation from the undersurface of machine frame part by means of a bracket 96, or the like.
  • the lower edge 92 of crown cam 94 which edge is the effective camming surface of that cam, lies in a common horizontal plane around all of the periphery of the cam except for a short arc in which it is extended downwardly to define a generally U-shaped lobe 98.
  • lobe 98 and its arcuate extent is necessarily such that it is not engaged by the end of a lever 86, 86' until the tongue 50, 50' of the lift arm 40, 40, situated beneath that lever, has contacted lobe 60 on plate cam 54, to elevate the lift arm and corresponding sleeve to yarn holder unseating position.
  • the leading edge of lobe 98 coincides with a point on the circular path of the yarn holders at least as late as, and preferably slightly later than, the point thereon coinciding with the leading edge of plate cam lobe 60.
  • the invention also includes means for accumulating the ejected yarn holders whereby they are kept out of the way subject to collection at periodic intervals when desired.
  • a suitable accumulating means may take the form of a V-shaped trough 100 (see FIG. 1) formed of sheet metal, or the like, which is attached at its front edge to the rear edge of rail 12 with its rear end supported by means, not shown, above the floor or other surface upon which the machine rests. It will be apparent that such a trough will be adequate to receive the yarn holders as they are ejected from the machine and several ejected holders, designated S are shown in the trough awaiting collection in FIG. 1.
  • a winding machine having a yarn carrier mounted for rotation about a vertical axis and adapted to support at least two yarn holders at circumferentially spaced points therearound, said carrier including at each of said points a member disposed on a vertical axis fixed with respect to said carrier, said member mating with an end of said holder to support the holder vertically on said carrier, and means operable from time to time for revolving the carrier through an are equal to the circumferential spacing of said yarn holders on said carriers to successively bring said holders from and to a reserve position to and from an active unwinding position, the improvement which comprises means for effecting relative axial movement between each supporting member and the holder associated therewith upon movement thereof from active to reserve position to unseat the holder and means adapted to engage an unseated holder and forceably displace the same laterally of said vertical axis.
  • said unseating means includes a lift member for each holder support member, said lift member being pivotally mounted on said carrier for movement vertically to unseat each holder from the corresponding support member, and a cam operatively associated with said lift members to move the same vertically at a locus on the path of said carrier "about its vertical axis intermediate the active and reserve position of said holders, said cam being fixed against rotation.
  • a winding machine as in claim 2 wherein said holder displacing means comprises lever means pivotally mounted on said carrier above each holder support member, said lever means being adapted upon pivoted movement thereof to engage the corresponding holder and impel the same laterally of the support member axis, and a second cam fixedly mounted on said machine, said cam having a cam surface contacting said lever means and operative to pivot the same at a predetermined locus on said surface, said locus corresponding to a point on the path of said carrier at which the holder being moved from active to reserve position is unseated from its sup port member.
  • lever means comprises a hollow tube surrounding each holder along a major portion of its length and terminating at a level above the upper limit of said holder support members, said tube being mounted on said carrier for pivotal movement in a vertical plane, and a crank arm affixed to each tube and engaged by said last-mentioned cam.
  • a winding machine having yarn carrier mounted for rotation about a vertical axis and adapted to support at least two yarn holders at circumferentially spaced points therearound, said carrier including at each of said points a member disposed on a vertical axis fixed with respect to said carrier, said member mating with the end of a holder to support the holder vertically on the carrier, and means operable from time to time for revolving the carrier through an arc equal to the circumferential spacing of the holder support members to successively bring said members and the holders supported thereon from and to a reserve position toand from an active unwind- 7 8 ing position, the improvement which comprises means for member axis and means for moving said last-named eifecting relative axial movement between each member means to operative position after the holder is unseated.
