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.
  • 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:
  • first moving means (504) to move the end of the guide element to the coil (510/511 ) on one side and on the other over said reel (544) substantially parallel to the reel axis (579-508-588-589, see Fig. ⁇ a and Fig. ⁇ i) and second moving means (567, 577-579,588-585-581-588-589- 591 see also Fig.5i) in order to be able to move said end of said first guide wire element (24) as it moves away perpendicularly to the reel axis in order to follow the increase of diameter of the coil during the winding (544-27) and - a wire-guide extension (510 from 24 / 511 from 25), separated from the first (24.25), capable of guiding at least one section of said wire immediately before to unwinding over said reel.
  • WO0025952 (EP1126935 - Danieli) explains and claims (preamble - non- characterizing part of main claim) 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.
  • the solution WO0025952 (EP1126935), though trying to resolve only a part of the problem with the fixed position of the wire-guide extension, positions said cord in a fixed way perpendicular to the reel axis.
  • 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.
  • Solution to the Problem and Disclosure of the Invention The problem is solved with the characteristics of the claim main.
  • the depending claims provide particularly advantageous solutions. Advantages In this way it is possible to obtain the great advantage of a wire coil with perfectly aligned and adjacent turns and not superimposed according to the exact calculated angle of spiral winding (Y) that corresponds to the ratio between the diameter of the wire and the diameter of the reel/ diameter of the coil.
  • the wire in winding has the same angle and therefore the same inclination as the turn that is already wound.
  • the solution regarding the medium diameter of the coil Dm (D-d)/2.
  • 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.
  • FIG. 1 A schematically represent two views, a lateral view of the winding group, respectively with the entire first guide wire (4) and enlarged in the end portion of said first guide wire on the winding machine-winding reel (1), wherein there is a single guide wire (4) which is designed in double in its oscillation from side to side on the reel, namely from its maximally lowered position "B” to its maximally raised position "A", the reel being positioned by its vertical rotation axis (1).
  • Fig.2, 2A schematically represent an overview with respect to the Figure 1, in full and partially enlarged on the reel side, in the stage with minimum diameter, namely at the beginning of coil formation (C position).
  • Fig.3, 3A schematically represent an overview with respect to Figure 1 , in full and partially enlarged on the reel side, in the stage with maximum diameter, namely at the end of coil formation (position D).
  • 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.
  • the end of the guide wire (4) can follow any forming point of the coil (R) according to an established program.
  • 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).
  • the problem of the wire-guide extension aligned to the first guide wire that involves the enlargement of the turns to the ends and with the danger of superimposition in the intermediate zone as in the previous solution (EP1126935) is solved.
  • 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.
