Definitions

  • the present invention relates to yarn guiding devices for making cops withfrusto-conical ends, in particular for use with yarn throwing machines.
  • Such machines include a rod extending transversely to the axis of the cop and one end of which carries a guide eye for the yarn constantly applied on the cop.
  • said rod is carried at its other end by a support having a rectilinear reciprocating movement along a path parallel to said axis and said rod is given, about an axis perpendicular both to said first mentioned axis and to said rod, an oscillation movement with respect to said support in phase with said rectilinear reciprocating movement, said oscillation movement being controlled in accordance with the variation of the radial distance from said guide-eye to the cop axis so as to make the amplitude of said oscillation movement the smaller as said radial distance is greater.
  • Fig. 1 is an elevational view of a yarn guiding device according to the invention, the parts being shown in the position they occupy at the beginning of a cop winding operation.
  • Fig. 2 is a similar view showing the parts at the end of the cop winding operation.
  • Fig. 3 is a plan view corresponding to Figs. 1 and 2, the solid lines corresponding to Fig. 1 and the dotted lines to Fig. 2. i
  • Fig. 4 is a vertical sectional view on the line IV-lV of Fig. 1.
  • Figs. 5 and 6 are respectively an elevational view partly in section and a plan view respectively of a yarn guiding device made according to another embodiment of my invention.
  • a bar 1 is given, through means shown on Fig. 4, a rectilinear reciprocating motion alon its own axis, which is parallel to the axis of the cop 16 journalled in frame F.
  • the yarn guiding device includes a plate 2 rigid with bar 1.
  • a support 4 is pivoted to plate 2 about an axis 3.
  • This support 4 carries, rigid therewith, an arm 5 of cylindrical shape.
  • a spindle 6 is journalled about an axis intersecting the axis of arm 5.
  • the upper end of spindle 6 carries a rod '7 rigid therewith and the end of which carries a guide-eye 8 for the yarn 9.
  • lever 10 On arm 5 is pivotally mounted a lever 10 the upper end of which forms a cage for a ball 11 through which rod 7 is slidably guided.
  • the lower end of lever 10 is constantly applied against the upper edge 2a of plate 2 under the action of a compression spring 12 mounted on arm 5 (Figs. 1, 2 and 3).
  • a link 13, hinged without play to the lower end of lever 10, is slidable freely through a ball 14 which is freely oscillable in a socket 15 fixed with respect to the frame.
  • This socket 15 has its center located at equal distances from the respective ends of the cop.
  • a cam shaft C journalled in the frame of the machine and driven by pinions P P carries a helical cam C in the groove of which is slidably engaged a roller i carried by a sleeve I fixed to bar 1.
  • lever 1i which is constantly applied against the edge 2a of plate 2 is caused to slide along arm 5, thus compressing spring 12 and moving away from spindle 6.
  • Ball 11 follows the displacement of lever 10 by which it is carried and slides along rod 7.
  • Bar 1 transmits to support 4 its reciprocating rectilinear movement the amplitude of which is equal to L.
  • Spindle 6 and arm 5 therefore have reciprocating movements of the same amplitude L, but the supplementary oscillation of lever 10 about the axis of arm 5 due to the action of link 13 and swivel joint 14 causes ball 11 to have a displacement the amplitude of which is longer by 2l than the amplitude of displacement of spindle 6. This length 2! is substantially constant during the whole winding operation.
  • the rod 7 is therefore given a movement which is the resultant of the'displacement of the spindle 6 about which it is pivoted and of the complementary oscillating displacements of ball 11.
  • Guide-eye 8 therefore has a movement of an amplitude equal to L+2l multiplied by the ratio of the distance between guide-eye 8 and spindle 6 to the distance between the center of ball 11 and said spindle'6.
  • This operation permits of obtaining the two frusto- "conical ends of the cop, said ends being equal or different according as the center of ball 14 is or is not located in the plane dividing length L into equal portions.
  • spring 12 is more and more compressed as the diameter of the cop is increasing, which simultaneously increases the pressure with which guideeye 8 is applied against said cop.
  • the spindle 6 on which rod 7 is oscillable is slidable in two guiding bearings provided respectively in arm 5 and in spindle 3.
  • a rigid rod is provided so as constantly to connect said spindle 6 with plate 2 and thus to determine the axial position thereof in its bearings in accordance with the radius of the cop.
  • such a rod 18 is constituted in the form of a stirrup of suitable length the ends of which are engaged in corresponding recesses provided at O in plate 2 and the middle portion of which extends through a ring 18a rigid with the top portion of spindle 6.
  • the dimension of this ring in a direction parallel to its axis is suiticiently small to enable spindle 6 to have rotations of small amplitude as required for the operation of the device.
  • Lever 10 is in the form of a hollow tube the upper portion of which is provided with longitudinal slots and forms an open cage for ball 11 through which rod 7 is freely slidable.
  • Link 13 hinged without play to the lower end of lever N, is in this case a rod the axis of articulation 17 of which with lever 10 is located in a plane perpendicular to that containing substantially arm 5, lever 10 and rod 13.
  • Rod 13 can slide freely in ball 14 through which it passes.
  • Guide-eye 8 distributes the yarn of the cop 16 against which it is constantly applied by the tension of yarn 9 and the weight of the movable portion of the apparatus.
  • a yarn guiding device for making cops having frustoconical ends which comprises, in combination, a frame, a cop journalled in said frame about a given axis, a support mounted in said frame to be both slidable along a second axis parallel to said first mentioned axis and pivotable about said axis, means for imparting a reciprocating motion to said support along said second axis, a lever pivotally mounted on said support about a third axis, fixed with respect to said support and at right angles to said second mentioned axis, the upper end of said lever forming a cylindrical socket, a ball movably fitted in said socket, said ball being provided with a diametral hole, a rod pivoted at one end to said support about a fourth axis transverse to said first and third mentioned axes and to said rod, said rod fitting slidably in said diametral hole to extend transversely to said first mentioned axis, a yarn guiding-eye at the other end of said rod in contact with said cop
