Definitions

  • Double barrel winders are known devices which are used for the continuous winding of fine wire, for example telephone wire.
  • the barrel can carry two coils and with each transfer it rotates 180 °.
  • the full spool which then appears in the unloading position, is removed and replaced by an empty spool while the other spool receives the wire from an outside line.
  • the barrel performs a new tilting of 180 °.
  • the wire breaks by the tensile force which it undergoes when the hooking disc associated with the reel empties the hook.
  • wire guides pass the wire over a fixed knife which cuts it.
  • the object of the invention is a double barrel winder for alternating winding, on two reels of an elongated product with high resistance, characterized in that it comprises an auxiliary shearing and hooking device, mobile between an inactive position away from the barrel and an active position in view of an empty coil mounted on the barrel and control means for bringing the shearing apparatus into the active position during each tilting of the barrel.
  • Figs. 1 and 2 show the general construction of the double barrel winder corresponding to the first embodiment. It is a device intended to wind cables of the order of 6 to 12 mm in diameter on spools whose cheeks have a diameter of around 50 cm.
  • the general construction of this winder comprises a base 1 supporting a frame 2 in the form of a cage, the opposite walls of which bear two bearings 3 and 4 between which a barrel 5 is pivoted.
  • the latter comprises a shaft 6 and two parallel longitudinal members 7 and 8 integral with the shaft 6.
  • the shaft 6 is rotated by a toothed wheel 9 engaged with a driving pinion (not shown).
  • the drive shafts 10 and the pivot shafts 11 supported by the side members 8 and 7 in bearings make it possible to drive two coils 12 in rotation.
  • the drive is done from a single motor 13 which is supported by a base 14 secured to the spar 8.
  • Two pulleys 15 each drive one of the two pulleys 16 which are coupled by disengageable couplings 17 to the shafts 10.
  • the device 18 rotates with the barrel. It transmits power to the motor 13 and to the various control means supported by the barrel during the rotation of the latter.
  • the wire to be wound on the coils 12 comes from an accumulator 19 passing over idler pulleys 20.
  • idler pulleys 20 We see in fig. 2 that from the last of the deflection pulleys it extends tangentially to the shaft of the closest of the two coils 12, i.e. the one that is being filled.
  • a hinge pin 21 mounted under the ceiling of the cage-shaped frame 2 supports a rocker 22 which is controlled by a jack itself suspended from the pin 23 and acting in the direction of the arrows d.
  • the flip-flop 22 can take an inactive position shown in mixed lines in FIG. 2, then an intermediate position (not shown) where it is ready to enter into action and finally an active position shown in solid lines in FIG. 2.
  • This scale which comprises as main part a straight flat profile 24 carries on the one hand a hydraulically operated clamp 25 and on the other hand a guide member 26 provided with a roller (not shown). These two elements are located on the profile 24 in locations such that when the rocker is placed in the active position, they engage on either side of a coil 12 which is then empty.
  • Figs. 3 and 4 show the detail of the shearing mechanism and the attachment mechanism in the first embodiment of the object of the invention.
  • the shears 27 comprises a fixed blade 28 which is fixed for example by welding against the profile 24, a hinge pin 29 mounted on the fixed blade 28, and a movable blade 30 connected to the fixed blade by the hinge axis 29.
  • This movable blade 30 is controlled by a jack 31, the body of which is articulated on two legs 32 integral with the flat profile 24, (fig. 4).
  • the rod of the jack 31 is in the retracted position, the shears are in the open position and the wire F comes to engage between these two blades when the rocker arrives in the active position.
  • the attachment device here further comprises, associated with the rocker 22 a push lever 33 which is mounted on the hinge pin 29 and which is biased by a spring 34 so as to avoid exaggerated stresses on the wire F .
  • the wire hooking means also include elements which are associated with the barrel and the coil 12.
  • a lever 36 On a drive plate 35 which is integral with the drive shaft 10 is mounted, in a predetermined orientation, a lever 36 engaged between two legs 37 integral with the plate 35.
  • the lever 36 pivots about an axis of articulation 38 relative to the legs 37 and it is biased by a spring 39 adjustable in a housing of the plate 35.
  • a rigid blade 40 On the part of the bent lever 36 which extends perpendicular to the axis of the barrel 5, is mounted a rigid blade 40 which passes through a hole 41 formed in the cheek of the coil 12 in the vicinity of its barrel. It is this blade 40 which, under the effect of the spring 39 will press the end segment of the wire F after its cutting against the barrel of the coil 12.
  • the rocker 22 is still equipped with a pusher 42 to hydraulic or electromagnetic control which, at the moment when the shears 27 comes into action, displaces a mobile element 43 in the direction of the arrow g so as to pivot the lever 36 and move the blade 40 away from the drum of the coil 12.
  • the lever 33 can freely pivot with the movable blade 30 of the shears 27 and push the end segment of the wire F in the direction of the cheek of the coil 12 so that, when the action of the element 42 ceases, the spring 39 returns the lever 36 and the blade 40 to the position shown in FIG. 4.
  • the end segment of the wire F is subject to the barrel of the coil 12.
  • the shears can therefore be brought back to the open position by retraction of the rod of the jack 31, so that the pusher 33 returns to the position shown in solid lines in FIG. 4 after opening of the clamp 25.
  • the lever 22 can then be brought back to the inactive position.
  • auxiliary means which will be discussed later can be held in place to retain the free segment of the wire F which, after cutting, represents the end of the full coil placed in the lower position on the barrel 5. In this which concerns the empty coil 12, its clutch can be brought back to the active position and the winding can continue until the coil is also full.
  • the blade 40 does not press the extreme limit of the end segment of the wire F, but on the contrary, the part of the wire F which is moved by the lever 33 remains free .
  • This short segment may represent a risk of deterioration during the winding of the first turns and to avoid this, in a variant of this embodiment, the hole 41 could be given the shape of an elongated and curved segment or the shape of a banana and provide the lever 33 of a rim capable of making the end of the wire F penetrate into this banana-shaped hole by bending it slightly against the extreme edge of the hole.
  • Figs. 5, 6 and 7 represent the second embodiment.
  • the shears 27 are here represented in a schematic manner.
  • the fixed blade 28 is fixed obliquely to the section 24 in order to provide more space for the elements of the attachment device which operates here in a different manner from what has been shown in FIGS. 3 and 4.
  • the shears 27 are ordered in exactly the same way as in the first embodiment.
  • the hooking device is capable of bending the end segment of the wire F immediately after the shears have fulfilled its function so that part of this end segment is directed parallel to the axis of the spool 12.
  • the folding means comprises a rotary folding head 44 secured to an axis 45 passing through a guide 46 secured to the profile 24.
  • a lever 47 on which a rod is articulated ( schematically represented at 48 in fig. 5) which is connected to the rod of a jack (not shown).
  • the head 44 and the shaft 45 move in the direction of the axis of this shaft while progressively approaching the drum of the coil 12.
  • the head 44 In the active position (fig. . 6), the head 44 is in the immediate vicinity of the barrel of the coil 12, its axis being disposed radially with respect to this coil.
  • the head 44 has in its front face which looks towards the drum of the coil 12, a central stud 49 and a peri rib spherical 50 which extends approximately over a quarter turn.
  • this head 44 also has a cylindrical passage 51 in which slides a pin 52 which is parallel to the stud 49.
  • This pin is retained at its rear part by a slide 53 mounted on the axis 45 and this slide is itself controlled by the rod 54 of a small jack 55 secured to the bearing base 46.
  • the pin 52 and the central stud 49 are in the relative positions shown in FIG. 7 in solid lines, so that the wire F is caught between these two parts of the attachment device.
  • the shears whose blades 28 and 29 are seen in FIG. 7 has cut the wire F, the end segment of the latter is retained between the elements 52 and 49 of the attachment head which is rotated clockwise as seen in FIG. 7 so that the end segment of the wire F is bent at 90 ° and its free end goes towards the hole 41.
  • the jack 55 is controlled so as to withdraw the pin 52 in the axial direction and a second jack control (not shown) acting on a lever 56 rotates in the support 57 a shaft 58 which is solidiare an arm 59 carrying a pusher 60. The latter moves from right to left in FIG. 7 and engages the bent segment of the wire F in the hole 41.
  • FIGs. 8 and 9 show a third embodiment which is in fact a variant of the embodiment which has just been described.
  • a folding head 61 here comprises two cylindrical studs 62 and 63 of the same diametrically opposite dimensions between which the wire F is bent after the shears 27 has entered ac tion.
  • This head 61 is supported by a base 64 integral with the profile 24 which represents the body of the rocker 22, and it is controlled by a lever 65 in the same manner as in the second embodiment.
  • it is the whole of the head 61 which is removed by means of a jack (not shown) at the moment when the pusher which is designated here by 66 must come into action.
  • This pusher is also supported by an arm 67 secured to a shaft 68 which rotates under the effect of a lever 69 also controlled by a jack.
  • a lever 69 also controlled by a jack.
  • the head 61 being movable in the axial direction relative to the rocker body 24, it could also be the shaft 68 for pivoting the pusher 66.
  • the fourth embodiment which will now be described comprises a hooking device which uses a hole 70 formed in the barrel of the coil 12 in the vicinity of its cheek.
  • the body 24 of the lever 22 carries the fixed blade 28 of the shears 27 of which the hinge pin 29 can be seen in FIG. 10 and the movable blade 30.
  • a console 71 carrying a folding pin 72 which, when the shears is actuated, is placed in the position shown in FIG. 11.
  • a folding tool 73 and a pusher 74 carried by a base 75 are in the position shown in FIG. 10.
  • These two tools are articulated around an axis 76 integral with the rocker body 24 and they are controlled by actuator rods acting along lines 77 and 78.
  • the tool 73 is therefore controlled so as to fold the end segment of the wire F as seen in FIG. 12 against the folding pin 72 after which the shears are opened and the tool 71 returns to its inactive position such that the shows fig. 14.
  • the pusher 74 is controlled as seen in FIG. 13 so as to engage the end segment of the wire F through the hole 70.
  • the control of the shears 27 and of the pin holder 71 is carried out by a jack similar to the jack 31 and mounted on the body 24 of the rocker. It is understood that these various elements can be easily mounted on the scale and brought in the immediate vicinity of the location where they are to work, the wire being securely fixed by means of the clamp 25.
  • the wire F is not of such a nature that it can be easily bent at 90 ° and rigidly keep its shape
  • it may be advantageous to use as a hanging device a device designed on an even different principle.
  • This is what the two variants shown in figs represent. 15 to 19.
  • the flip-flop 22 also comprises a body made up of a flat section 24 and this body carries a clamp for fixing the wire F.
  • this clamp is not fixed as was the case in previous embodiments. Indeed, a tilting arm 79 (fig.
  • a hydraulic clamp 80 is provided at the free end of this arm 79.
  • the latter is controlled by a jack 81 mounted on the body 24 so that during the hooking operations, once the wire F has been cut, the end segment of this wire can be moved in the direction of the wire, i.e. in the direction of the arrow h in fig. 15.
  • a pusher 82 which no longer has the function of promoting the folding of the wire F, but which is only intended to bring the extreme segment of wire F in the vicinity of the cheek of the coil 12 when the shears are put into action.
  • a second plunger 83 is articulated on a rigid arm 84 secured to the body 24 of the rocker 22 and this second plunger 83 is controlled by a jack 85.
  • FIG. 17 shows the dimensions of the devices described seen in the direction of arrow B.
  • Figs. 18 and 19 show a variant of the embodiment of FIGS. 15 to 17, a variant in which the control means are simplified and lightened.
  • the drum of the coil 12 has here a clearance 92 in which are housed a retaining pawl 93 and a spring 94.
  • the body of the seesaw 22 carries a shears 95 but it is not here a shears with two blades pivoting one on the other.
  • the shears 95 comprises a fixed blade 96 and a movable blade 97 which is driven by a jack 102 and which slides longitudinally on the blade 96.
  • the fixed blade 96 has the shape of a slide, the flank 98 of which can be seen at fig. 18.
  • this slide can have a dovetail profile.
  • a guide member 99 which moves in translation between the two positions shown in FIG. 18, respectively in solid lines and in broken lines when the shears are actuated.
  • the device must still be capable of another movement and for this reason, the whole of the fixed support 96, 98 of the shears 95 is pivotally mounted on the body 24 around a hinge pin 100.
  • a jack (not shown) makes it possible to move this assembly between the position shown in broken lines in FIG. 19 and the position shown in lines full.
  • the articulation shaft 100 is integral with a base 101 fixed to the body 24. As can be seen in FIG. 18, the jack 102 pivots with it. This transverse movement of movement allows the guide 99, the shape of the profile of which is visible in FIG. 19, hook the wire F and bring it forcibly into the position where it is shown in solid lines in FIG. 19, so that the displacement of the rod of the jack 102 then necessarily brings it opposite the entry of the housing 92.
  • the movable clamp (not shown in FIG. 18) which has gripped the wire F is moved under the effect of a cylinder similar to the cylinder 81 in order to bring the free end of the wire F into the position shown in broken lines in FIG. 18, where it is hooked by the pawl 93.
  • the downstream part of the wire i.e. the part which forms the end segment of the full reel, is retained by the clamp 26 located at the free end of the rocker 22.
  • the clamp 26 located at the free end of the rocker 22.
  • the presence of this free end of the wire could be troublesome and it is also possible, in a variant not shown, to provide, in addition to the lever 22, a retaining arm pivoting around of the same axis as this lever and the end of which is provided with a roller which presses the free end of the wire from the full spool, for example against the pivot axis 6 of the barrel.
  • This simple system avoids the effects of an unwanted unwinding of the spooled yarn on the full spool located at the bottom of the winder as seen in fig. 2.
