Definitions

  • the present invention relates to a continuous winding double winder comprising two reels supports of parallel axes provided with hook discs, a cutting device moving back and forth parallel to said axes and a transfer device which comprises means for guiding the movable wire so as to bring the latter in the vicinity of the barrel of the empty spool at the time of transfer and a deviating device which separates the wire from the hooks associated with the full spool and engages it in the path of the associated hooks to the empty reel.
  • Winders of this kind are already known. For them to operate under conditions of maximum productivity, it is essential that the winding can be carried out at high speed and that the transfer of the wire from the full reel to the empty reel at the end of the filling of each reel takes place as simple and rational as possible so that these operations can be automated without difficulty and without risk about the reliability and regularity of the operations. It is also essential that during all these operations the wire does not undergo undue stress risking breaking it. Indeed, any wire breakage leads to delays which disrupt the operation of the installations located upstream of the winder.
  • a particularly delicate operation in the series of maneuvers which constitute the transfer is the attachment of the wire by the hooks associated with the empty spool.
  • the two hook discs are located in the same plane, so that the thread must be deflected along a path forming a double bend at the time of transfer in order to avoid hooks associated with the full reel while passing through that of the hooks associated with the empty reel.
  • German DOS 1 955 246 describes several deflection devices which comprise either two vertical thread-pushing bars moving parallel to the median axis of the machine under the effect of jacks, or a vertical bar and two horizontal bars controlled independently at the time of transfer.
  • German DOS 1 959 377 it is intended to use as a deflection device vertical wire pushers controlled by jacks and as a wire breaking device, electrodes capable of burning it.
  • Patent FR 2 274 537 provides as a deflecting device, on the one hand, a vertical retaining rod secured to a horizontal lever which pivots so as to bring said rod close to the hook-carrying disc associated with the full reel and 'on the other hand, a meeting body which moves parallel to the axes of the coils.
  • a deflecting device on the one hand, a vertical retaining rod secured to a horizontal lever which pivots so as to bring said rod close to the hook-carrying disc associated with the full reel and 'on the other hand, a meeting body which moves parallel to the axes of the coils.
  • these two components must be ordered separately.
  • US Patent 3,695,528 also describes a diverter device of complex construction.
  • This device includes a swivel base fitted with two twin bars extending vertically but it further comprises two vertical thread pushers moving parallel to the axis of the coils and which are controlled alternately.
  • the wire is deflected by one of the twin bars of the swivel plate and by one of the wire pushers mounted on jacks.
  • the object of the present invention is therefore to improve the reliability of double winders of the kind mentioned at the start, by simplifying the arrangement of the deflector devices, as well as their control and the general control of transfer operations.
  • the winder according to the invention is characterized in that the deflector consists of two twin elements secured to a base, in that the latter is rotatably mounted around an axis perpendicular to the plane defined by the axes of the reels and in that the guide means and the twin elements of the deflector are arranged so that at the time of transfer the wire engages between the twin elements by a displacement parallel to the pivot axis of the deflector and the latter performs a rotation of a predetermined angle in one direction or the other depending on the direction of transfer.
  • the deflector is a one-piece member, its control is simplified and the above-mentioned difficulties are eliminated. Furthermore, as the thread engaged between the twin elements of the diverter while the latter is rotating, the functions of these elements are preserved. One of them releases the wire from the hook area and the other engages it in this area. Preferably, it is with this second element that the knife will be associated.
  • Figs. 1 and 2 show the general arrangement of the machine.
  • the frame 1 carries drive and support means for two coils 2 and 3 of parallel axes, on which a wire 4 is wound alternately.
  • Each coil support comprises a shaft 5 (fig. 2) carried by two bearings and rotational drive means 6 which will not be detailed here, but comprise for each shaft a gear motor and a control device ensuring a winding at constant speed.
  • the shafts 5 carry at their end projecting from the frame 1 each a disc 7 provided at its periphery with hooks 41.
  • the outer end of each shaft 5 also includes mounting means for one of the coils 2 or 3. These means mounting extend in overhang, so that access to the machine from the side of the front face seen in FIG. 1 is free.
  • a cutting support 8 also fixed in overhang and comprising two parallel guide bars 9 and a control screw 10 which is coupled at 11 to a rotary drive element 12 itself.
  • the screw 10 rotates the cutting trolley 13 back and forth over the entire axial length of the coils, so that the cutting pulley 14, mounted on the side of the trolley 13, also travels the entire length of the coils alternately in one direction and in the other.
  • the cutting pulley 14 is tangent to a vertical plane parallel to the axes of the coils 2 and 3 and located at equal distance between these axes. This vertical plane called below, the median plane of the machine, is indeed a plane of symmetry for the operation of the transfer means.
  • the wire 4 which is wound alternately on one and the other of the coils 2 and 3 comes either from a supply coil, or from an extrusion line, or from another installation.
  • the winder is equipped with an accumulator 15 shown diagrammatically in FIG. 1.
  • This accumulator comprises a pulley 16 mounted on a vertical arm 17 capable of pivoting with respect to the axis 18. This arm will be stressed by elastic elements so as to ensure that the tension on the wire 4 during winding is approximately constant .
  • the accumulator 15 also acts as a withdrawer.
  • the pulley 19 is integral with a drive shaft 20 which is coupled to a motor 21.
  • the transfer means are constituted by a tilting assembly generally designated by 22 and by a diverter 23 (fig. 3).
  • the tilting element essentially comprises an upright 24 which is normally in a vertical position. It is carried at its lower end by a horizontal shaft 25 parallel to the axes of the coils and located in the median plane previously mentioned. To maintain it in a vertical position, there is provided in the vicinity of its upper end a locking member ⁇ 26 provided with a handle 27 and a rod 28 biased by a spring.
  • the end of this rod engages in a hole provided in the stationary assembly 29.
  • the latter consists essentially of welded sheets and carries the transfer means. It is fixed by its base against the front face of the frame 1 as seen in FIG. 3. It also carries the diverter 23 which will be discussed later.
  • the shaft 25 extends to the left (fig. 3) inside the frame and carries at its end limit switches (not shown).
  • the upright 24 carries a transverse bar 30 to which are fixed two fixed shafts 31 extending in overhang parallel to the median plane.
  • These shafts 31 each support a wire guide consisting of a diabolo 32 and a cylindrical drum 33.
  • These two elements rotate freely on the shaft 31 independently of one another and the diameter of the drum 33 is equal to outside diameter of the diabolo.
  • the positions of elements 31 and 32 are fixed by stops so that the dolly and the drum can rotate at different speeds and avoid the effects of inertia.
  • the profile of the drum is engaged at its end on the dolly to ensure the passage of the wire from one to the other smoothly during the transfer.
  • the drum extends over approximately 4/5 of the length of the coils while the diabolo is located in the vicinity of the cheek closest to the hook disc 7.
  • the thread guides that form each drum 33 and the corresponding diabolo 32 embrace the wire 4 and more precisely the part of this wire which extends between the cutting pulley 14 and the spool on which the wire is wound.
  • the transfer operation is controlled by moving the tilting assembly 22 from the position shown in solid lines or normal position, in the position shown in dashed lines where it is tilted to the left, the upright 24 abuts on one of the oblique spacers 34 of the base carrying the bearing of the crew 22. As can be seen in FIG.
  • the wire is then brought into a position where it is tangent to the barrel of the empty reel 3, and it can be understood that if the tilting unit is then brought back to the middle position after the wire has been hooked by the disc associated with the coil 3 which rotates in the direction of arrow A, the winding on the coil 3 will take place symmetrically with respect to the winding of the coil 2 which rotates in the direction of arrow B.
  • the displacement of the crew tilting to the right will operate the transfer symmetrically, from the coil 3 assumed to be full to the coil 2 assumed to be empty.
  • this deflector comprises a vertical shaft 35 which pivots on the fixed assembly 29, a horizontal disc 36 integral with the shaft 35, two twin vertical bars 37, of cylindrical section diametrically opposite with respect to the axis of the disc 35 and which extend upwards to a level slightly higher than the axis of the coils, the upper ends of the bars 37 being slightly bent in divergent directions.
  • the diverter 23 also includes a knife 39 secured to the disc 36 and whose blade is vertical, the edge being tangential to the disc 36.
  • the diverter 23 is coupled to the shaft 25 of the tilting crew by a gear of angle 38, so that by pivoting approximately 45 ° from the normal position to the left, the tilting assembly causes the deflector 23 to pivot in the clockwise direction from the normal position as it is visible in fig. 4 where the two bars 37 are located substantially in the median plane up to the position of FIG. 5 where each of the bars 37 has rotated approximately 135 °, the knife 36 having come to be placed in the position oriented upwards and to the left.
  • the displacement of the transfer means brings about a cutting of the wire between the two coils and the attachment of the end attached to the production line on the disk associated with the empty coil.
  • An oblique ramp 40 constituted by a cylindrical bar is fixed to the support 29 in an oblique position and in the median plane. Its lower end is folded vertically and engages between the upper ends of the bars 37.
  • the full spool 2 can then be stopped and separated from the spool holder, then replaced by an empty spool.
  • All of the transfer means are arranged so as not to hinder in any way access to the spool support, which facilitates the service of the machine.
  • these transfer means are fully supported by the base 29, so that they can be assembled and disassembled as a unit in one piece. This latter feature also constitutes one of the advantages of the device described.
  • These automatic control means could detect the end of filling of the full reel, or operate under the effect of a command of another type. While the cutting device moves the wire so as to form the last layer of the spool from the cheek opposite the hook disc to the cheek located on the side of this disc, they control the tilting of the upright 24 from the middle position shown in fig. 1 in solid lines towards the extreme position located on the side of the empty reel. At the same time, the deflector is rotated as described above, so that when the thread guide 33 over which the thread passes brings the latter into a position close to the drum of the spool, it is hooked by the hooks associated with the empty coil but avoids those associated with the full reel.
  • the rotary drive of this spool causes the wire to be cut on the knife 39 after which the tilting assembly is returned to its middle position, the full spool is stopped and discharged automatically so that it can be replaced by an empty spool whose rotation will start shortly before the start of the next transfer operation.
  • the automatic control of these operations is particularly simple in the winder described since the deflector is a one-piece piece kinematically linked to the tilting assembly, so that a single command is sufficient for all these operations.
