Definitions

  • This invention relates to stranding machines, that is, to machines for stranding together a number of wires to form a stranded electric conductor or a wire rope.
  • each component wire is drawn off from a supply reel or bobbin and led to and passed through a rotating guide or lay plate which lays it helically, generally around an advancing centre core, which may be a single wire or a previously stranded group of wires.
  • the invention is concerned with stranding machines of the kind in which (or in a section of which) the wire-com taining bobbins are mounted with their axes coincident with the machine axis, and the wires as they are drawn off from the bobbins due to the forward movement imparted to the stranded conductor by the draw ofi wheel or capstan are guided towards a lay plate by a rotating flyer.
  • a stranding machine having one or more sections of axially aligned bobbins which eliminates the need for handling the bobbins in such section or sections and considerably reduces the duration of stoppages due to the bobbins of such section or
  • our improved machine which comprises a section'or unit (ora number of;sections or units), consisting of two'axially aligned groups of axially aligned bobbins, provision-1's made for drawing oiI wires from each of the two groups alternately and guiding them towards a lay plate. Means are.
  • Figure 3 is a fragmental sectional view drawn to a still larger scale and showing in greater detail the way in which one of the groups of bobbins of the section or unit shown in Figure 2 is supported and the speed of the bobbins controlled,
  • Figure 4 is an enlarged cross-section taken on line IVIV in Figure 2
  • Figure 5 is a fragmental elevation of one of the sections of two groups of axially aligned bobbins of a modified form of the machine shown in Figures 1-4, and
  • Figure 6 is a fragmental end view of the brakedrum shown in Figure 5.
  • FIG. 1a and 1b it is ex plained that-the machine shown is designed to strand together thirty-seven wires to form a stranded conductor comprising an inner layer of SIX wires laid around a central wire, an intermediate layer of twelve wires laid around the inner layer and an outer layer of eighteen wires laid around the intermediate layer. To this end it comprisessix axially aligned sections or units designated I, II VI. These sections or units are similar and each consists of two axially aligned groups of axially aligned bobbins.
  • Each section comprises a main support tube I which is rotatably supported in bearings V I .2, 3 and is rotatably driven by a chain and sprocket drive 4, the rear section,.section I, being driven from lay shaft 5, sections II and III forming the intermediate group being driven through a second lay shaft 6, and the front section being driven through a third lay shaft. 1. All three lay shafts are driven by a motor 8, which through lay shaft 1, also drives a draw-off capstan 9 and a take-up reel 10.
  • the front end of the main support tube of the rear section, section I carries a lay plate 55 which guides the wires from the section to the stranding point for that section.
  • the corresponding parts of the sections III and VI each carr a lay plate which guides the wires from the section and from the section or sections with which it is associated to form a group, to the stranding point for the group,
  • a pre-spiralling head i2 is located in front of the lay plate of the second group of sections, and a second rare-spiralling head E2 in front of the lay plate of the third group of sections.
  • Each of these heads :2 is driven by a chain and sprocket drive l3 from the lay shaft 5 at the same speed as the main support tube of section I.
  • the main support tube 1 of each section carries a pair of bobbin support tubes 21 and 22 each of which surrounds the main support tube and is rotatably supported thereon and adapted to be driven by the support tube and independ-' ently of that tube, alternatively.
  • On the front bobbin support tube 21 is rotatably mounted a group of six bobbins 23, each of which is adapted to be driven by the bobbin support tube through one or more friction couplings 25.
  • These couplings are adjustable. They may be adjusted to allow wire to be drawn off the bobbin under appropriate tension, that is without undue tension on the one hand or over-running of the bobbin on the other.
  • a second group of six bobbins 24 is similarly mounted on and similarly driven by the rear bobbin support tube 22.
  • the means for guiding wires 26 drawn off from each of the two groups of bobbins 23 and 24, al tcrnately, may comprise a pair of flyers (one for each group) either of which can be held stationary whilst the bobbins of the group with which it .is associated are being rotatably driven independently .of the. group being driven by the main support tube, for the. purpose of re-winding them.
  • the part or parts of the fiyer which rotate around the bobbins can be made readily detachable to allow re-winding of the bobbins when driven independently of the main support tube. .We prefer however, to use a two-position fiyer 27 capable of guiding wire from each of the two-groups of the section alternately.
  • each of the wires 26 from the front group of bobbins 23, is guided by the fiyer 21, first outwards from. the machine axis then backwards to a point between the two groups of bobbins 23 and 2 5, then inwards towards the main support tube l and then forwards, between'the front bobbin tube 2! and the main support tube 1, towards the lay plate H ( Figure 1).
  • each of the wires 25 from the rear group of bobbins is guided by the flyer 21 in its alternative position first outwards and then forwards to a point between the two groups of bobbins 231 and 24, then inwards towards the support tube and forwards between the front bobbin tube and thesupporttube to the lay plate i, as shown by the broken 1ines in Figure 2.
  • the flyer 27 may comprise a disc 28 (or alternatively a number of radially extending spokes) mounted on the main support tube I between the two bobbin tubes 2! and 22 and carrying at its periphery a, number of arms 29, for instance, two disposed on diametrically opposite sides of the main support tube I.
  • These arms extend more or less parallel with the axis of the machine either forward or rearward and carry pulleys 3b which serve to guide towards the disc 28 the wires from either the front group of bobbins or from the rear group, depending upon the position of the arms 29.
  • the disc carries appropriately placed pulleys 3
  • the arms 29 of the flyer may be pivotally attached to the disc 23 as shown in Figures 5 and 6 so that by swinging each arm through an arc of it may be transferred from the front group of bobbins 23 to the rear group 25.
  • each arm 29 may, as shown, be supported at one end in a bearing 33 on the disc 23 and at its other end in a bearing 34 carried by a radial arm 35 on the front end of the front bobbin tube 2
  • each of the arms 29 is transferred from one position to the other by removing it from one pair of bearings 33, 34 and inserting it into the second pair 36, 31, one or both bearings of each pair being laterally openable, as by removal of a retaining pin 34a or 3112, to facilitate the transfer.
  • This arrangement is preferred to the pivotal form of attachment because it has the advantage of leaving the periphery of the disc 28 free to serve as a brake drum 38 for a central hand brake 38 which is operated by an electric thruster til and enables the section to be brought rapidly to rest when desired or in the event of wire breakage.
  • the brake band 39 is replaced by a pair of brake shoes 58.
  • the wires 25 passing forward between the main support tube I and the bobbin tube 21 are segregated from one another by arranging anumber of small bore tubes M around the main support tube l and passing one wire through each of these tubes.
  • the friction couplings 25 may be of any suitable form but those between each two bobbins 23 preferably comprise a, flanged collar 42 which carries a friction disc on each face of its flange and which is permitted to move longitudinally with respect to the bobbin support tubes 2
  • the friction couplings 25 between bobbins 22 are similar.
  • the friction coupling 25 preferably takes the form of an axially adjustable collar 43 which serves as an abutment and carries a friction disc'on the side facing the adjacent bobbin, and the friction.
  • coupling 25 at the rear end of the front tube .(and the front end of the rear tube) preferably takes the form of a collar 44 which carries a 'jacent to it. This second collar 44 is allowed to move axially along the bobbin tube 2
  • (or 22) carrying the bobbins 23 (or '24) from which wire is being drawn off is locked to the support tube l, as by means of a dog clutch 41 (or 48).
  • ) carrying those bobbins isv permitted to rotate relative to the main tube I by releasing the dog clutch 48 (or 41) and is driven at an appropriate speed, for instance, by means of a chain drive 49 to a chain wheel 58 mounted, in the case of the front bobbin tube 2
  • the thrust pins 46 of the bobbin group being rewound are locked in their positions of maximum thrust as by links 51, to enable the bobbins to be driven without slip by the independently driven bobbin support tube.
  • ( Figure 1) carrying a number of wire guides l5l (one for each bobbin of the section).
  • This bar may be reciprocated longitudinally by a constant velocity cam '52 so as to uide the wires 25 uniformly'on to the bobbins that are being re-wound from a corresponding number of swifts 53.
  • the latter may be mounted upon a movable support so as to serve both groups of bobbins.
