Definitions

  • This invention relates to a machine for winding onto bobbins a ribbon containing at least two optical fibres arranged mutually parallel and aligned.
  • the object of the present invention is to solve this problem by providing a machine for automatically, and without interruption, winding a fibre optic ribbon onto bobbins, which ensures complete absence of ribbon twist.
  • the machine of the present invention comprising a support element for rotatably supporting two bobbins having a common centre plane, the two bobbins being able to be rotated in the same direction, said support element being rotatable about an axis intermediate between the axes of rotation of the two bobbins and coplanar with these axes, so as to be able to replace one bobbin when full of ribbon with the empty other bobbin by simply rotating the support element, the ribbon hence making contact with the core of the empty bobbin along a circular arc of predetermined width, and further comprising means for gripping the ribbon, for cutting it and for retaining the initial end of the ribbon on the still empty bobbin, these means acting on that ribbon portion in contact with the core of the empty bobbin.
  • the fibre optic ribbon 10 the cross-section of which is shown considerably enlarged compared with reality, consists of four optical fibres 12, 14, 16 and 18, each covered with a cladding - indicated by 13, 15, 17 and 19 respectively - of transparent material with a lower refractive index.
  • the four optical fibres covered in this manner and arranged adjacent and aligned are incorporated into a common plastic sheath, to hence form the ribbon 10.
  • FIG 2 shows very schematically a plant 21 for producing a fibre optic ribbon wound onto bobbins, the plant being formed from various machines including a winding unit 22.
  • a winding unit 22 receives the ribbon 10 which then passes successively about a first deviation roller 23, a flywheel 24, a take-up roller 25 and a second deviation roller 26, to finally wind onto a first bobbin 27 which is shown nearly full in the figure.
  • the bobbin is rotatably carried by a support device 28 in the form of a vertically arranged disc, this latter being rotatable clockwise (arrow A of Figure 4) about its central horizontal axis, indicated in the figure.
  • An empty second bobbin 29 is rotatably carried on the same support device.
  • Each of the two bobbins 27 and 28 is rotatable on a spindle 32 on which a rotated faceplate 33 is also rotatable.
  • the bobbin is kept pressed against the faceplate 33 so that when this latter is rotated the bobbin also rotates by being dragged.
  • a circular hole 34 In one side of each bobbin there is provided a circular hole 34 into which, on mounting the bobbin onto the spindle 32, there is inserted an overall cylindrical hollow projection 35 whose hole extends through a hole in the faceplate 33, said projection 35 forming part of a gripping, cutting and retention device for the ribbon 10, this device being indicated overall by 36 and being fixed to the faceplate.
  • the device 36 is described in detail hereinafter.
  • the support device 28 can be rotated through 180° clockwise to pass from the position shown in Figure 3 to the position shown in Figure 5, and passing through the intermediate position shown in Figure 4.
  • the result is an exchange of positions between the full bobbin 27 and the still empty bobbin 28.
  • the ribbon 10 makes contact with the core 31 of the empty bobbin 29 along a circular arc subtended by the angle B.
  • the bobbin 27 continues to receive ribbon 10.
  • the ribbon gripping, cutting and retention device 36 shown overall in Figure 6 is illustrated enlarged and by itself in Figure 8, in which the casing 37 of the device 36 is cut away to allow its interior to be seen.
  • Figure 7 represents an enlarged view of the detail C of Figure 5.
  • the gripping of the ribbon, its cutting and the retention of the initial end of the ribbon on the bobbin take place along that portion of ribbon 10 subtended by the angle B (in which the ribbon makes contact with the core 31 of the still empty bobbin 29).
  • Figure 7 shows the three most significant angular positions of the device 36 as the bobbin rotates through the angle B.
  • the state of the cutting and retention device 36 is as shown in Figure 8.
  • the casing 37 contains a gripper 38 formed from two jaws 39, 40 pivoted on a common pivot 41 carried by a slide 42.
  • This latter is supported by two connecting rods 43, 44, indicated schematically in the figure, to form a parallelogram. Consequently the slide 42 can move relative to the bobbin spindle 32 while always remaining parallel to this latter.
  • a spring 45 maintains the slide 42 in the rest position shown in Figure 8.
  • a control shaft 46 can be rotated by a suitable actuator device, not shown (formed for example from a lever operated by an electromagnet or pneumatically), to rotate the arm 50 rigid with the jaw 39 through a predetermined angle via a lever system comprising connecting rods 47 and 48.
  • a spring 49 acting on the jaw 39 maintains the gripper 38 open.
  • the jaw 40 is rigid with an arm 51 which is retained in a position against a stop 52 by the action of a spring 53.
  • Figure 9 shows the situation of the cutting and retention device 36 (shown only partially for simplicity) corresponding to the angular position C of Figure 7.
  • the situation shown is obtained by rotating the shaft 46 anti-clockwise through a predetermined angle.
  • the spring 49 prevents movement of the node 54, so that the slide 42 advances leftwards until it touches the relative side of the faceplate 33, hence elongating the spring 45. Consequently the gripper 38 also advances leftwards, so that the ribbon 10 lies between the jaws 39 and 40.
  • the ribbon 10 rests flatly on the lips 55 (see also Figure 7) of the hollow projection 35.
  • Figure 10 shows the situation of the cutting and retention device 36 corresponding to the angular position defined in Figure 7 by the angle D. Following a second anti-clockwise rotation of the shaft 46 through a predetermined angle the force of the spring 49 is overcome, so that the jaw 39 lowers to press the ribbon 10 against the jaw 40 which has remained at rest because of the reaction of the spring. The gripping force on the ribbon is proportional to the reaction load of the spring 53.
  • the angular position defined by the angle E in Figure 7 corresponds to the situation illustrated in Figure 11, obtained by a further rotation of the shaft 46 which also overcomes the force of the spring 53.
  • the ribbon 10 still retained between the two jaws 39 and 40 of the gripper 38, is lowered onto a cutting edge 56 of a knife 57 (not shown in Figures 6 to 10 for simplicity) until the ribbon 10 has been completely cut.
  • the knife 57 is rigid with the slide 42 (even though this is not shown in Figure 11) and consequently moves with it. It should be noted that even in the subsequent angular positions the ribbon 10 remains retained by the gripper 38, to hence wind about the core of the new bobbin 29.
  • the now free end 58 ( Figure 7) of the ribbon 10 is wound about the full bobbin 27, which can then be removed and replaced by an empty bobbin.
  • the ribbon 10 is cut without any twisting of the ribbon.
  • the ribbon remains retained both during and after its cutting, the initial end of the ribbon also remaining retained on the empty bobbin 29, so that the ribbon can wind onto this latter.
