Definitions

  • the present invention relates to a method of manufacturing windings comprising a plurality of son wound in parallel unwindable in the form of a single assembled wick, these son being for technical use, in particular based on glass or thermoplastic polymer. According to another aspect of the invention, it also relates to the device for implementing this method.
  • the manufacture of an assembled wick is the result of a complex industrial process which consists of obtaining threads from molten glass threads flowing through the die orifices. These fillets are drawn as continuous filaments, and then these filaments are combined into base yarns, which yarns are then generally collected in the form of cakes intended for internal use because they are difficult to transport. The cakes are then positioned on creels that feed a winder on which is formed the cylindrical ball of roving (wick) assembled. The products obtained are not free of defects such as undulations or loops from differences in the tension of the basic threads.
  • the coils are also in the form of straight-sided windings or in the form of cylindrical windings, and are generally referred to as "roving” or “ball” depending on their destination final.
  • the form of coil is made using winders, which as their name suggests, are responsible for winding at very high speed (about 10 to 50 meters per second) the glass threads that were previously sized.
  • winders ensure the drawing and winding of these filaments and the operating parameters of these winders condition with those of the die the dimensional characteristics of the yarn, in particular the title expressed in tex (the tex being the weight in grams of 1000 meters fiber or yarn).
  • a winder is placed roughly under a die, from which descends one or more strands of son gathered at a point or several points, these son are then wound live on a rotating spindle by means of one or more sliders at a groove for axially distributing the threads gathered along one or more reels by a reciprocating movement synchronized with the rotation of the spindle, this slider or these sliders are part of a subset that the is called encroisure, which is mounted on a movable support allowing its permanent repositioning during the winding, parallel to the spindle axis to allow it to maintain a certain distance between the slider or sliders and the outer cylindrical surface of the coil or coils whose diameter changes throughout its or their construction.
  • a first family of winders is said to restart centuries, that is to say that an operator is responsible for manually restarting the windings, and it is possible to wind on the same winding several son, up to eight, even sixteen threads (each of the threads consisting of a strand of filaments).
  • a second winder family is called automatic restart.
  • the winder is more complex than those described above, and it further comprises a barrel supporting a plurality of pins (generally at least two in number), each of the rotatable spindles, being adapted to stretch and wind at least one stack successively on each of the pins, one of the pins being active while the other is at rest to allow the unloading of the stack just made, a automatism coupled to the various actuators of the winder being responsible for performing the passage of at least one strand of filaments from one spindle to the other during the rotation of the barrel.
  • an installation according to the invention comprises a die having a quantity of a molten thermoplastic material, a rotating spindle for drawing the threads of material coming from the orifices of the die as well as the winding of the son. It also comprises an assembly and guide device and a crimping device comprising a wire guide.
  • This wire guide comprises an aperture facing the pin communicating with an internal guiding zone provided at its periphery with at least two notches.
  • the present invention is specifically concerned with winders whose recovery is automated that do not have the disadvantages mentioned above, and which allow the winding on the same coil, the winding separated according to an optimal quality, of at least two strands of characteristics ( in particular number of wires per strand, choice of material forming the wire %) different or identical
  • the locks are constantly preserved and identified during the entire transition phase, namely during the passage from one winding spindle to the other, thus making it possible to wind on a spool. same winding at least two wicks separately.
  • the winder essentially comprising a frame, this frame comprising a barrel movable in rotation with respect to the frame, said barrel being from minus two pins each adapted to support at least one winding, each of the pins being rotatable about a first axis substantially perpendicular to the diameter of the winding so as to simultaneously stretch and wind at least two bits in the form of a winding of separated locks, and a device at least provided with a slider for depositing on the surface of the winding wicks separated from one another, characterized in that it further comprises a device for separation can occupy a first position in which it allows one hand to separate from each other wicks running from a die to the curse ur and secondly to maintain them in a remote position, and a second position in which it does not interfere with the path of the wicks.
  • a winding obtained by the method described above comprises a plurality of turns, preferably at least two, each of the turns consisting of at least one wick consisting of a material and being separated from one of them by a step p.
  • a winder 1 according to the invention illustrated in figure 1 , it comprises a metal frame obtained by a technique of mechanically welded metal elements previously machined or available as standard commercially.
  • This frame essentially comprises a substantially rectangular base resting on legs suitably placed so as to correspond to the jig or the spacing of the forks of a pallet truck or a similar handling device to facilitate the implementation of this winder in a fiberizing position.
  • this closed cabinet-shaped structure is provided with the control and control devices necessary for the various regulations of the various components which will be described later in the present description, of networks, hydraulic, electrical, compressed air, and other necessary fluids the operation of said organs.
  • This barrel 2 On the closed structure cooperates a cylinder 2 which projects laterally.
  • This barrel 2 is rotatably mounted about an axis of rotation and is held within one of the walls of the closed structure by means of a plurality of guide members (ball crown, ball slide for example).
  • this barrel 2 constitutes a support assembly of pins 3, 4.
  • the barrel 2 has two pins 3, 4, in diametrically opposed positions [if there is only one pin, it is not possible to make the automatic transfer].
  • the barrel 2 makes it possible to bring a spindle 3 previously unloaded and provided with at least one blank sleeve (within the meaning of the invention, a sleeve is a support made of plastic, cardboard or other material which is intended for receiving the spool of thread or the winding of threads) in the winding position and another spindle 4 having its full cuffs in the unloading position by rotations of 180 °.
  • a sleeve is a support made of plastic, cardboard or other material which is intended for receiving the spool of thread or the winding of threads
  • Each of the pins 3, 4 integral with the barrel 2 is a rotating assembly adapted to stretch and wind the wire 5 on a sleeve previously introduced on the spindle. This winding is performed along a first axis of rotation substantially parallel to the axis of rotation of the barrel relative to the structure of the frame.
  • FIG. 1 there appears another element which is essential for the realization of a coil.
  • This is the device for positioning and guiding the wire on pin 6.
  • it is a movable cursor in a groove, the cursor moving linearly along a second axis substantially parallel to the first axis; the assembly being mounted within an assembly that can move closer to or away from the outer peripheral surface of the coil during the winding thereof.
  • This set is commonly called "crease device”.
  • a crimping device 6 comprises a member shaped as a movable slider 7 linearly within a groove, this movable slider 7 makes it possible to position at least one wire 5 on the spindle 3 or 4 in rotation, the movement printed by the wire guide 7 consisting essentially of a movement of oscillations or beats only over a length of the coil.
  • the slider 7 is movably mounted in a movement back and forth in translation on a shaft integral with the frame and parallel to the axis of the spindle, this second translational movement thus making it possible to cover the length of the coil.
  • the cursor 7 represented in figure 3 allows the simultaneous removal on the surface of the same and single winding of at least two wicks, each of the wicks consisting of a plurality of son 5, these two wicks being separated by a pitch p in the form, in this case , two turns almost joined.
  • This type of winding with separate turns guarantees optimal unwinding, without the risk of knots and parasitic loops.
  • This slider 7 is of generally trapezoidal shape whose base 8 is substantially parallel to the axis of rotation of the winding.
  • the slider 7 has a curved or inclined surface delimiting in fact guide surfaces 9, 10 which, when moving the slider in a direction substantially parallel to the axis of rotation of the spindle, intercept the trajectory of a first bit in a direction of displacement and a second bit in the other direction of alternative displacement, these bits being derived from a die 11 (visible in FIG. figure 1 ) placed above the winder 1, these wicks thanks to these inclined guide surfaces thus being directed towards a projecting wall 12 with respect to the base 8 of the slider 7.
  • This projecting wall constrains each of the locks in a retention zone 13, 14 and immobilization shaped in a groove (on the figure 3 , it appears 2 throats, one for each wick).
  • the wick is free to slide with the least possible friction, moreover, the material constituting the guide surfaces and the grooves is chosen so as to locally have a high hardness and a coefficient of friction. the smallest possible so as not to destroy and damage the wick of filaments and in particular at its sizing.
  • the slider 7, substantially trapezoidal, has inclined walls at its sides 9, 10 and at the inlet walls of each of the grooves 13, 14 so as to promote the guide of the wick to the bottom of the groove which is parallel axis.
  • the inventors have envisaged interception of the trajectory of the locks not by an alternating movement of the slider 7 and have preferred to privilege an indexing movement in position of the slider 7 with respect to the path of the locks, this indexing movement in position being facilitated by the different servocontrols both in position and in speed with which a winder of this type is provided, all the movements of the spindle (s) 3, 4, the barrel 2, the crimping device 6 and its slider 7, the separation device 15 which will be mentioned below, is controlled by a programmable controller responsible for controlling and controlling at all times this assembly for optimum winding of a winding.
  • the operation of the slider 7 is combined with that of the separation device 15, shown in FIG. figures 1 and 2 .
  • This separating device 15 is rotatably mounted relative to the chassis (hinge point marked A) and travels between a rest position in which the path of the locks is not deflected by the position of the separating device 15 and a so-called working position during which the separating device 15 intercepts the path of the strands so as on the one hand to separate or separate them from each other and secondly to keep them separate during the transition phase.
  • the phase of transition is defined as the phase during which the wicks which have just been wound on a winding until a full spool is obtained from the winding and stretching on a first spindle must pass automatically (c that is to say without human intervention stimulus) on another spindle (due to the rotation of the barrel), this second spindle to allow winding the drawing strands of filaments on the surface of at least a second winding.
  • the pallet 16 globally forms a rhombus, one of the axes of symmetry is positioned in such a way that it separates, in a median plane, the path of the strands, each strand passing on either side of this median plane.
