Definitions

  • the present invention is concerned with a method for making a strand of wires and feeding the same at high speed and an apparatus therefor, and more particularly, it relates to a method for making a strand with a plurality of single wires delivered from a wire supply source, such as the novel multiseetioned wire container, a plurality of bobbins superposed one upon another on a common vertical shaft, or bundle or bundles of single wires, and then feeding the resulting strand outside the system.
  • a wire supply source such as the novel multiseetioned wire container, a plurality of bobbins superposed one upon another on a common vertical shaft, or bundle or bundles of single wires
  • One of such subtypes is to make a strand of wires, without rotating the feed bobbin about the axis of the running wire, but rotating only the takeup bobbin about the axis of the running wire.
  • Another one of such types is to make a strand of wires by rotating only the feed bobbin about the axis of the running wire, without rotating the takeup bobbin about the axis of the running wire.
  • the remainder of these three types is to make a strand of wires, without rotating either the feed bobbin or the takeup bobbin about the axis of the running wire, but by rotating, about either the feed bobbin or the takeup bobbin, the flyer which carries the wire-guide roller.
  • the container feed method which is designed to effect the making of a strand by the use of a wire supply source which is a hollow cylindrical container in which is stored the wire in the form of piles of loops and by forming a strand from the wire paid out from this container.
  • either the take up bobbin or the feed bobbin is rotated about the axis of the running wire.
  • the weight of these bobbins being considerably great, the apparatus required to be designed so as to have a high-mechanical strength sufficient for overcoming the centrifugal force produced and applied thereto by the rotation of the bobbin.
  • the flyer which was rotated required a considerably great radius.
  • the container feed method of the prior art had the disadvantage that, owing to the fact that the wire container per se is rotated, the piles of wire loops contained therein tended to be lifted up in the container, causing the entanglement of the wire, that accordingly, it was impossible to perform high-speed operation for the sake of avoiding the lifting and the resulting entanglement of the loops of wire, and that, as a result, the wire had to be fed at an undesirably low speed.
  • the primary object of the present invention to provide a method for making a strand of wires and feeding the same at a high speed by the use of an apparatus having the arrangement comprising a wire supply source, such as the novel multisectioned container, a plurality of bobbins superposed on upon another on a common shaft which consists of the central vertical columns of the bobbins, or bundles of wires, and by withdrawing a plurality of wires from said wire supply source, smoothly making a strand with these wires and feeding the resulting strand outside the system, and also provide an apparatus suitable for putting this method into prac tice.
  • a wire supply source such as the novel multisectioned container
  • a plurality of bobbins superposed on upon another on a common shaft which consists of the central vertical columns of the bobbins, or bundles of wires
  • Another object of the present invention is to provide a method for making a strand of wires and feeding the same at a high speed, said method being such that, when applied to the feeding of the strand formed by a strander, there can be omitted not only the use of a conventional twister or the device for making paired, tripled or quaded wires from single wires, but also the inclusion of the wire twisting operation, the use of bobbins for winding and carrying the twisted wires and all other operations such as applying the twisted wires around the bobbin and applying and removing the bobbins to and from a strander, and further the accessory equipment required for these purposes, and the present invention also provide an apparatus which is suitable for putting this method into practice.
  • Still another object of the present invention is to provide a novel wire feeding, lay-making and discharging apparatus which can employ a conventional single wire-container, bobbin or wire bundle as the wire supply source and which can feed the wire at a high speed while imparting sufficient lay thereto, by the provision of a flyer having a wire guide roller and circling around such a wire supply source.

  • said flyer brackets 8 and 8, the driving pulley 5 and the main shaft 3 integrally constitute the wire feed flyer section.
  • Wires especially single wires We are fed from, for example, concentric two annular cylindrical sections Cl and C2 (in the example of FIG. I) which constitute a cover container indicated in general by P and having coaxially arranged multiple compartments. These plurality of wires (two wires in the example of FIG. 1) are collected together as they pass through a collecting die 11a mounted on said rotary member 11 in coaxial relationship with the rotational axis of said member 11.
  • the driving pulley 5 of the flyer section is driven, via a belt 18, by a pulley 17.
  • such devices may be provided in series relations as shown generally at A and separately A,, A A in FIG. 2 or FIG. 3. Or, alternatively, they may be arranged conveniently in two rows consisting of pairs of opposing devices.

  • Individual wires We are withdrawn from the respective annular cylindrical sections C C of the coaxially multisectioned wire container P and these wires are collected together by the collecting die 11a.

  • the flyer section is of the arrangement that a pair of brackets 8 and 8' are securely attached to the upper surface of the driving pulley 5 at diametrically opposing sites, and connecting rods 12 and 12' are attached to these opposing brackets 8 and 8'.
  • the weight distribution about the rotary shaft is balanced and accordingly, high speed operation is feasible.
  • the provision of the guide rings 12a, 12b, etc. serves to prevent the radial outward warping or projection of the strand W. This also contributes to high-speed rotation of the flyer section.
  • the tray 42 need not be strictly stationary, but instead, it may be rotated at a low speed, provided that the speed does not cause entanglement of the wires delivered from the wire supply source and that the speed is within the range in which no lifting of the wire loops takes place due to the centrifugal force applied, especially in the case of a container of the aforesaid coaxially multisectioned type.
  • the direction of rotation of the tray is preferably opposite to the direction of rotation of the flyer section. However, these two members may be rotated in the same direction. It should, therefore, be noted that the ratio of the number of teeth between the toothed section 41 and the gear 7a in the previously described planetary gear mechanism may not necessarily be identical with the ratio between the toothed section 21 and the gear 7b.
  • the rotary member 11 is driven separately, although not shown, in such a way that it is rotated at the same number of revolutions with the flyer section, and in which the connecting rods 12 and 12', etc., are omitted.

  • the next step is to rotate this collecting die.
  • the next step is to alter the direction of the run of the collected wires, and to pass them through the outermost end of the flyer which circles round the aforesaid multisectioned container.

  • the bobbins are provided with guide rings G G and G respectively.
  • wires are withdrawn from the bobbins while sliding along the circumferences thereof.
