Definitions

  • the invention relates to a machine for winding wire or cable on coils, for example sheathed electric wire.
  • the wire is cut on the latter, that is to say stored in contiguous turns in regular plies superimposed on the cylindrical barrel. of the coil. This regular arrangement of the wire is essential so that its subsequent unwinding takes place in the best conditions, that is to say freely and without damage.
  • the length of wire carried by the spool is predetermined.
  • the outer ply of contiguous turns is not, in most cases, complete, so that the wire, when it is hooked to one of the cheeks of the spool to avoid its untimely unwinding, follows a path according to a non-contiguous turn, therefore of a pitch different from that of the preceding turns, going from the end of the incomplete sheet to the cheek of the coil, introducing an undesirable discontinuity in the arrangement of the wire, and a loosening subsequent possible external turns.
  • the wire is cut only beyond its point of attachment to the cheek of the spool, so that the free end protrudes from the perimeter of the cheek , which can hinder the movement of the coil by rolling on the edges of his cheeks, and exposes the protruding thread.
  • the second technique is to provide holes radial in the spool of the spool, close to its cheeks, and to introduce the end of the wire to be wound in one of these holes leaving a free end of a desired length protruding inside the barrel or substantially parallel to the outer face of the cheek.
  • This solution is preferred because, thus, this free end does not reach the periphery of the coil, and it provides good conditions for the electrical tests.
  • it has the drawback that it is necessary, before winding, to introduce the wire into the hole in the spool of the spool by a manual operation, which results in a significant drop in the speed of production of spools filled .
  • the object of the invention is to eliminate the drawbacks mentioned above and to provide a machine making it possible to wind wire automatically, without manual intervention, on spools succeeding each other on the machine, leaving the wire two free ends, the inner free end projecting from a radial hole in the spool of the coil, and the outer free end being an extension of the last turn of the winding, without it being necessary to hook this external free end to a cheeks of the coil, and without transverse deviation of said wire at the end of winding.
  • the machine according to the invention makes it possible in particular to obtain perfectly stored wire with contiguous turns on a spool, leaving two free ends easily accessible, the wire not undergoing any excessive stress due to its winding and its maintenance.
  • the automatic machine according to the invention for winding wire on spools in succession is characterized in that it comprises means for supplying empty spools, means for rotating said spools around their axis, means for locating a radial hole in the barrel of the spool and keeping it in position after locating, means for introducing into said hole a predetermined length of wire intended to form the internal extended end, means for winding and cutting the wire on said spool, means for measuring the length of wire in rolled on the spool and cause the rotation of the spool to stop when the desired length of thread is reached, means for sticking the thread at the end of winding to the turns already wound on the spool at a point constituting the end of the last contiguous turn of the wire, means for cutting the wire downstream of the bonding point at a distance equal to the length of the desired end of the outgoing external end, means for keeping the free end of the wire in position after cutting during the drying of the glue, and means for discharging the full reels.
  • the machine according to the invention comprises a frame 1 (FIG. 1) formed by a horizontal base part 2 and a vertical plate 3. Through this plate 3, is pivotally mounted a horizontal shaft 4 controlled by a motor 5, and carrying at its end 6 a circular plate 7 parallel to the plate 3.

  • the thread guide 99 which, during winding, is oriented, by virtue of its pivoting attachment to the axis 76, towards the instantaneous point of tangency of the thread on the preceding ply of thread, returns to its rest position where it is an extension of the wire guides 104 and 105. At this time, a loop is formed near the pulley 97: the advance of the cutting table during the subsequent operation makes it possible to eliminate it.
  • the movable part of the crew 136 is brought up by the jack 143 and the crew 136 itself is brought back to its rest position by the retraction of the rod of the jack 138 whose end 139 abuts against the crew's eyelet 136.
  • the cutting plate 87 is brought back by actuation of the motor 93 to its extreme initial position, near the capstan 109. Finally, the half-clutches 18 and 73 are freed from each other.
  • the motor 5 controls the 90 ° rotation of the turntable, which brings the packed spool to the so-called drying position III, where the thread is held on the spool by the shoe 14.
  • the operation of winding the thread on the reel being the longest of the four loading, winding, drying and unloading operations, it is the end of the winding operation at station II, described above, which controls the rotation of a quarter turn of the turntable.
  • the turntable again rotates 90 ° under the action of the motor 5 to bring the full reel from the drying position III to the unloading position IV.
  • the cam disc 17 of the shaft 10 comes into contact with the ramp 172, which causes the shoe 14 to be lifted and thus release the rotation of the coil.
  • the washer 173 carried by the shaft 9 comes into contact with the belt 272, which causes the coil to rotate by rolling the washer 173 on the belt 272.
  • the length of the belt 272 and the diameter of the washer 173 are provided so that, when the full reel reaches the unloading position IV, the external free end 190 of the reel is located in the upper part of said reel so as not to hinder the operations of unloading which will be described.
  • the means with jacks provided in the extension of the shaft 9 are actuated to cause the retraction of the lugs 29 and, thus, the release of the coil.
  • the coil is pulled longitudinally out of its engagement on the tip 20 and is deposited on the inclined ramp 180 on which it is evacuated by rolling.
  • the arm 12 is provided a brake shoe 14 of length substantially equal to the width of the coils.
  • the extreme position of the cutting device can also be adjusted so that the wire guide 99, in this extreme position, is in a plane substantially tangent to the outer cheek of the coil.
  • the various motors fitted to the machine are of the variable speed type.
  • the object pursued by the invention is achieved, that is to say the supply of coils furnished with wire arranged in contiguous turns and in successive layers, and having two free ends extended , one by a radial hole presented by the barrel of the coil, and the other in the extension of the last turn of the last layer, without requiring fixing of said wire; to one of the cheeks of the coil and without changing the pitch of the winding at its end. Thanks to the bonding of the wire at the end of the winding, the coil obtained is of a very clear appearance and the wire is not subjected to excessive stresses. The electrical tests of the wire are easily done by connecting the two free ends and the unwinding of the wire can be done after simple peeling by tearing off the point of glue.
