Definitions

  • the invention relates to an apparatus which is adapted for automatically fastening the leading end of a yarn or wire in the course of being reeled, directly to the core of a conventional reel, without the aid of any adhesive tape, or any like additional fastening means.
  • the operation of the apparatus according to the invention is such that the lead­ing end of the yarn or wire fastened to the reel core will not protrude from the reel winding, whereby the leading end of the yarn or wire will not cause any problem to arise, due to its interference with parts of a machine using the yarn or wire, which is, for example, required with the steel wires for the manufacturing of tyre carcasses.
  • numeral 1 denotes the center counterhead of a yarn or wire winding machine, which is rotatably fitted onto one end of a stem 2 being axially guided in cylinder 3 and being prevented from rotating in said cylinder by a key 4 and a groove 5, the said stem being provided upstream and downstream of said groove with pistons 6, 7 which are oper­ated in a tightly sealed relation with the inner lateral surface of cylinder 3, having the ends closed by a disc 8 and a flange 9 which are provided with respective seals, the whole arrangement being such that two pressure chambers 10, 11 are formed at the interior of said cylinder, which can be alternately connected through suitable ducts and circuits to a pressurized air delivery source, or to a discharge, in or­der to promote the forward and rearward movement of the cen­ter counterhead, as required for its cooperation with the reel R on which the yarn or wire is being wound.
  • Numeral 12 denotes the frame supporting in a cantilevered manner the cylinder 3, and numerals 13 and 14 denote the ducts formed in the cylinder itself and in disc 8, for connection of chambers 10 and 11 with the circuit for axially driving the stem 2.
  • a collar 17 is rotatably but not axially movably fitted at a short distance there­from.
  • Numeral 18 denotes the bearings which allow the relat­ive rotation of members 3 and 17.
  • the collar 17 has at least one integral radial ear 19 with a conical seat 20, which is normally engaged by a spigot 21 driven by a cylinder-and-­piston unit 22 which is carried by the frame 12.
  • At least two guide rods 23, 123 arranged parallel to stem 2 are overhangingly secured by one end to collar 17, and lie, when the apparatus is at rest, in a horizontal ideal plane con­taining the axis of said stem.
  • the rod 23 is not shown in Figure 1 in its real angular position.
  • Slidably mounted on rods 23, 123 is an annular member 24 (see Figures 1, 2, and 3), and a ring 27 is provided in front of said member, and is situated at the interior of the space occupied by the said rods 23, 123, the said ring being connected to the mem­ber 24 by supports 28, 29.
  • the support 28 extends radially, away from the annular member 24-ring 27 assembly, in form of a suitably sized arm, which carries in its upper portion a fluid-pressure operated, double acting cylinder-and-piston unit 30 with its axis being arranged parallel to the axis of the center counterhead 1.
  • a conical jaw 31 Secured to the stem of unit 30 is a conical jaw 31 which is caused to act against a comple­mental conical jaw 32, that is secured to the body of unit 30.
  • the device formed by the jaws 31, 32 incorporates a cutter of the type being commonly used in an apparatus for automatically changing the reel in a yarn or wire winding machine, and such a cutter is not shown in the drawings, since it is conceivable and easily practicable by those skilled in the art reading what is disclosed hereinafter.
  • the clamping and cutting device 31, 32 is shown in opened condition, as well as in its active position. In this Figure, it appears that the distance between the unit 30 and the axis of the yarn or wire winding machine is such as to avoid that the said unit may interfere with the flanges of the greater diameter reel R which is usable in the yarn or wire winding machine.
  • annular member 24-ring 27 assembly When the apparatus according to the invention is at rest, the annular member 24-ring 27 assembly is set in its retracted position shown by dash-and-dot lines in Figure 1, and the device 31, 32 is correspondingly moved to the left-­hand side of Figure 1, so that it is off the stroke of the winding machine yarn or wire guide G.
  • the assembly 24, 27 is axially moved by at least one cylinder-and-piston unit 25 arranged parallel to the axis of cylinder 3 (see Figures 2 and 3), and having its stem secured to an ear 127 of ring 27, and its body secured to an ear 117 of collar 17.
  • ducts 34 are longitudinally formed in cylinder 3 and open into a matching number of res­pective annular recesses 35 being coaxially formed in the inner lateral surface of collar 17, and being isolated the one from the other by annular seals 36.
  • ducts 37 ( Figure 1) and ducts 38 ( Figure 3) which are radially formed in said collar 17, the inlet opening and the outlet opening of the cylinder-and-piston units 25 and 30 are connected to the said annular recesses, so that the said units can be controlled by acting upon the stationary ducts 34.
  • the yarn or wire winding machine is again stopped.
  • the actuation is commanded of the cylinder-and-piston unit 25, and the device 31, 32 is moved into the position shown by solid lines in Figure 1, in line with the pulley of the yarn or wire guide G, at standstill at Z1.
  • the friction means 16 abut against the disc 15, and the device 31, 32 is connected for rotation with the center counterhead 1.
  • the actua­tion is commanded of the cylinder-and-piston unit 30, for closing the clamping and cutting device 31, 32.
  • the yarn or wire extending from the yarn or wire guide G is being kept clamped in the device 31, 32, and the yarn or wire length extending from this device to the reel, is cut.
  • the filled reel with the reel winding bound by a self-adhesive tape to be discharged from the yarn or wire winding machine, while the center counter­head 1 is retracted simultaneously with the device 31, 32.
  • Special means not shown, since the same are known, prevent the yarn or wire from running over the pulley of the yarn or wire guide G.
  • the device 31, 32 is returned, along with the yarn or wire leading end, into its angular position in which it is vertically in line with the yarn or wire guide G at standstill at Z1, and is again connected for rotation with the center counterhead.
  • the yarn or wire winding machine is then re-started at a low number of revolutions, and the pulley of the yarn or wire guide G is moved toward the right-hand flange of the reel, to the position shown in Figure 1 by arrow Z2, where­upon the same is moved in the reverse direction.
  • the yarn or wire being held by the clamping and cutting device 31, 32, which is rotated together with the reel, is handled by the yarn or wire guide G, and is wound on the reel core.
  • the yarn or wire guide G has performed its backward stroke and has arrived at a position shown by arrow Z3 in Figure 1, and which is, for example, defined by a sensor, the yarn or wire guide G is automatically stopped.
  • the device 31, 32 is opened, and the cylinder-­and-piston unit 25 is actuated and retracted ( Figure 3), for the said device to be returned into its rest position.
  • the yarn or wire winding machine is nextly re-actuated, and the yarn or wire guide G is caused to run through the entire length of its normal traverse, which is apt to wind the yarn or wire on the whole extent of the reel core.
