Definitions

  • the present invention relates to a yarn guiding device for a revolving type automaic winder according to the preamble of claim 1.
  • a revolving type automatic winder as shown in Figure 11 is often used which is composed of one turret table 101 rotationally movably installed in a unit case 100, two bobbin holders 103a, 103b rotatably carried on the turret table 101 and on which bobbins 102a, 102b, respectively, are installed so that the yarns are wound around the bobbins 102a, 102b, a movable frame 104 that elevates and lowers in a vertical direction, a contact roller 105 rotatably attached to the movable frame 104, and a traverse device 106 located upstream side of the contact roller 105 as viewed in the direction of a yarn path.
  • the Examined Japanese Patent Application Publication ( Tokkou-Hei) No. 5-17149 proposes a method for initial yarn catching in such a revolving type automatic winder.
  • This method for initial yarn catching in a revolving type automatic winder is characterized by comprising separating the contact roller 105 from the bobbin holder 103a to set the contact roller 105 and the bobbin 102a in a non-contact state, moving a yarn catching guide 107 located at a standby position outside the turret table 101 so that the yarn catching guide 107 is located at a yarn catching position within a locus circle drawn by the bobbin holders 103a, 103b when the turret table 101 is rotationally moved, catching a yarn Y' on the yarn catching guide 107 while sucking the yarn Y' using a sucking device 108, increasing the speed of the yarn-catching side bobbin holder 103b to a value close to a steady-state winding speed, and rotationally
  • the Japanese Patent Application No. 2002-239860 proposes a revolving type yarn winder comprising at least two bobbin holders rotatably installed on each of two turret tables, and a contact roller and a traverse device disposed upstream side of each of the turret tables in association with the bobbin holders so that when the amount of yarn wound around a bobbin installed on one of the bobbin holders reaches a predetermined amount, the bobbin is switched to one installed on the other bobbin holder to allow the yarn to be wound around this bobbin, the yarn winder being characterized in that the two turret tables are disposed across a yarn path, in that the contact roller installed for one of the turret tables rotates in a direction opposite to that in which the contact roller instal led for the other turret table rotates, and in that the center of each contact roller, which, during yarn winding, comes into contact with the bobbin
  • the Examined Japanese Patent Application Publication ( Tokkou-Hei) No. 5-17149 requires that for initial yarn catching, the yarn catching guide move from the standby position outside the turret to the yarn catching position within the locus circle drawn by the bobbin holders when the turret is rotationally moved. Thus, the initial yarn catching is cumbersome. Further, the device according to the Japanese Patent Application No. 2002-239860 must have a complicated structure when the method according to the Examined Japanese Patent Application Publication ( Tokkou-Hei) No. 5-17149 is applied to this device. Consequently, the Examined Japanese Patent Application Publication ( Tokkou-Hei) No. 5-17149 cannot be put to practical.
  • yarns Y are usually fed from an upstream side of the winder, and while being sucked by one suction gun SG, the yarns Y are conveyed to initial yarn catching guides 8, 8' via traversing fulcrum guides 10, 10', as shown in Figure 1 .
  • the initial yarn catching guides 8, 8' are arranged laterally across a yarn path, it takes a long time to divert the yarns Y to the respective yarn catching guides 8, 8'.
  • the one of the yarns Y is caught on one (for example, the left-hand initial yarn catching guide) 8' of the initial yarn catching guides 8, 8' before the other yarn Y is caught on the other (right-hand) initial yarn catching guide 8.
  • This increases the time required for the operation because the yarns Y must be caught on the respective right and left initial yarn catching guides 8, 8'.
  • This in turn increases the amount of yarn sucked by the suction gun SG during the catching operation, that is, the amount of yarn Y that must be disposed of. As a result, production efficiency decreases and production cost increases.
  • a plurality of (in the present embodiment, eight) synthetic fiber yarns Y are wound around feeding rollers R1, R2; the yarns Y are continuously fed from a spinneret (not shown) of a spinning machine.
  • a yarn guide G is disposed at an outlet of the feeding roller R2 to separate the plurality of yarns Y from one another at predetermined intervals.
  • Traversing fulcrum guides 10, 10' are disposed downstream side of the feeding roller R2. As shown in Figure 6B , the traversing fulcrum guides 10, 10' regulate the plurality of yarns Y so that the yarns Y are arranged at intervals equal to those of a plurality of packages formed by a winder W.
  • the plurality of traversing fulcrum guides 10, 10' can be moved closer to each other in an axial direction of bobbin holders 3, 4, 3', 4' and collectively toward an operation plane. This allows the yarns to be easily caught on the traversing fulcrum guides 10, 10'.
  • a plurality of guide members 32 are arranged upstream side of a traverse device and in parallel in a direction orthogonal to the axial direction of the bobbin holders.
  • Each of the guide members 32 is projected from a bracket 31 and provided with a pair of traversing fulcrum guides 10, 10'.

  • the shaft 11 is pushed toward the interior of the machine body and the adjacent pairs of traversing fulcrum guides 10, 10' are separated from each other by a predetermined distance.
  • the main body of a unit case 1 of the winder W is shaped like a rectangular parallelepiped.
  • Bases 1' are provided at the bottom of the unit case 1 so as to extend to the vicinity of an operation space in front of the winder W (the left side of Figure 6 ).

Accordingly, the two bobbin holders 3, 4 are rotated clockwise, while the other two bobbin holders 3', 4' are rotated counterclockwise. As shown in Figure 6 , eight bobbins B are installed on each of the bobbin holders 3, 4, 3', 4' according to the present embodiment.
  • the elevating frame 5 carries contact rollers 6, 6' that contact bobbins B installed on the bobbin holders 3, 4, 3', 4' or yarn layers formed on the bobbins B, and also carries a traverse device (not shown) that traverses the yarns Y in the axial direction of the bobbins B. At least one of the contact rollers 6, 6' is borne by the elevating frame 5 so as to be pivotable independently of the elevating frame 5.
  • the contract rollers 6, 6' feed the yarns Y to the bobbins B, while coming into pressure contact with the bobbins B or the yarn layers formed on the bobbins B.
  • the contact rollers 6, 6' are contacted with the surfaces of packages in order to improve the shapes of the packages, while increasing the hardness of the packages.
  • the centers of the contact rollers 6, 6' which contact the bobbin holders 3, 4, 3', 4' or the yarns Y being wound, are each located between an imaginary segment (c) joining the centers of the two bobbin holders 3, 4, projected from the one turret table 2 of the turret tables 2, 2', and an imaginary segment (c') joining the centers of the two bobbin holders 3', 4', projected from the other turret table 2'.
  • the imaginary segments (c), (c') each joining the centers of the two bobbin holders 3, 4 or the two bobbin holders 3', 4' together form an inverted V shape at least at the position of winding start of the yarns Y.

  • the contact roller 6 provided for one turret table 2 of the turret tables 2, 2' rotates in the direction opposite to that in which the contact roller 6' provided for the other turret table 2' rotates.
  • the one turret table 2 of the turret tables 2, 2' rotationally moves in the direction opposite to that in which the other turret table 2' rotationally moves. Accordingly, the width of the whole winder W can be reduced. This reduces the installation space for the winder W to improve the space efficiency.

  • a bundle of yarns Y is caught on the feeding rollers R1, R2 and yarn guide G below the spinneret of the spinning machine while being sucked by the suction gun SG. Then, the traversing fulcrum guide moving shaft 11 is pulled out toward the operation plane to move the traversing fulcrum guides 10, 10' (from positions corresponding to the centers of the bobbins) to the yarn catching operation side. The yarns Y are thus threaded through the traversing fulcrum guides 10, 10'. On this occasion, the initial yarn catching devices 14, 14' are located at their standby positions shown in Figure 3A .
