Definitions

  • This invention refers to a winding machine for rolled wire or drawn wire according to the characteristics of the preamble of the main claim.
  • GB2058703 d.4/1981 is cited as an example of an automatic coiler.
  • DE821666 d.11/1951 that describes a wire winding system alternatively in two winding reels (11,12, Fig.8) that includes a device to form wire coils downstream of a wire working plant, provided with a wire-guide (13/14) with wire-guide moving means (15-13) to guide the wire to the respective winding coil (11,12) with wire-guide moving means (17) to move the end of the wire-guide to the coil (13) on one side and on the other above the respective reel (11-12) substantially parallel to the reel axis.
  • US4664329 (May 12,1987 in the name of Essex Group Fort Wayne Indiana US). This refers to a winding system for a segment of wire to form a wire coil that contains the stages of rotating a mandrel by means of the contact of the external surface of the mandrel with a belt in motion and guiding the wire above the rotating mandrel between the belt and the external surface of the mandrel.
  • the belt keeps the wire against the mandrel (reel) and when the mandrel rotates, the wire is wound in a coil on the external surface of the mandrel.
  • the belt maintains contact with the external surface of the coil and rotates the mandrel until the full length of the segment of wire is wound.
  • this patent also provides (Fig.1) a device to form a wire coil in the winding machine (26, 27) with winding reel, (508) situated downstream of a wire working plant, provided with driver wire rollers (13) and thereafter:
  • W00025952 ( EP1126935 - Danieli), which forms the basis for the preamble of claim 1, explains and claims substantially the same structuring as described above with the difference that the said wire-guide extension (510-511, 503-500) has devices that are always to be held perpendicular to the rotation axis of said reel.
  • a further prior art is represented by US2977747A (NYSTROM AXEL C ET AL) 4 April 1961 (1961-04-04). Both show a wire-guide extension in front of the reel always kept in the same position, which is substantially orthogonal to the rotational axis of the reel.
  • the aim of this invention is to avoid the aforementioned drawbacks to allow the formation of perfectly adjacent turns in the coil without the danger of superimpositions or the distancing of one turn from another.
  • An additional aim is also to be able to form a much more tightly wound coil with less danger that its lateral turns may loosen or unwind during the extraction from the winding mandrel or reel and/or its transportation to a binding machine that is at a distance and separated from the winding-machine.
  • the inclination angle (Y) is determined by comparing the angle at the top of a triangle whose height corresponds to the diameter of the current or average coil (d, D, Dm) and whose base is equal to the diameter of the wire Df.
  • the orientation of the inclination devices (71) can be provided as variable according to the winding passes. Namely, decreasing progressively.
  • the wire (F) originates from a rolling-mill plant or from a wire-drawing plant (not shown as prior art).
  • Wire-cutting means are also provided upstream, so that once the coil (R) is completed the wire can be deviated according to the prior art to another winding-machine (only one illustrated), thus allowing the unwinding of the coil already made by sending it to the binding-machine while at the same time another coil is formed.
  • a respective extension of the wire-guide (7) is hinged (70) with a respective countersunk entrance to allow the wire to proceed toward the reel (1) for the formation of the coil (R).
  • the wire-guide extension is carried near to a medium vertical surface passing through the axis of the reel for a suitable coil winder.
  • said wire-guide extension (7) can be directed on one side and on the other inclined with respect to the orthogonal axis of the reel to achieve the perfect winding of the wire in turns without the danger of superimposing one turn over the other that could otherwise occur with an orthogonal wire-guide extension fixed to the axis of the reel (front solution EP1126935 ).
  • said wire guide extension cord always takes an orientation according to the hypotenuse of a right-angled triangle whose cathetus corresponds to the orthogonal to said axis reel/mandrel that is the corresponding angle to the height the turn inclination of the wire whose winding inclination therefore corresponds also to said hypotenuse, on the contrary to the solution explained in EP 1126935 Danieli, whose direction corresponds to said cathetus and contrarily to solution US 4664329 Essex Group, whose direction can in one case correspond to said cathetus (intermediate position of the wire guide) and with much difficulty or only in particular cases can correspond to said hypotenuse. And therefore, contrary to the present solution in which the direction always corresponds in a fixed way to said hypotenuse both clockwise and counter-clockwise according to the away or return movement on the reel for the formation of the turns.
