Definitions

  • the present invention relates to a multipart reel for a coil of wire.
  • wire at the output of the drawing machines where it is formed and in further steps of its production process, is wound in coils held on reels, and that in a very common embodiment such reels can be disassembled in order to allow to separate the formed coils, which are sent to shipping, while the reels remain on site and are reused after reassembly.
  • the aim of the present invention is to provide a multipart reel featuring constructive simplicity and good functional characteristics.
  • a multipart reel for a coil of wire characterized in that it comprises:
  • the reference numeral 1 generally designates the upper flange, which comprises an outer ring 1a and an inner ring 1b, connected by a flat metal plate 1c in the presence of reinforcement ribs 1d, and is provided with spokes for connection to a central hub 2, which is monolithically connected to a column 3, with which a central hub 4 is monolithically associated at the other end.
  • the connecting spokes are divided into four pairs: a first pair, formed by the spokes 5a and 5b; a second pair, formed by the spokes 6a and 6b; a third pair, formed by the spokes 7a and 7b; and a fourth pair, formed by the spokes 8a and 8b.
  • the reference numeral 9 generally designates a slider which is slidingly associated with the column 3 and comprises first of all a main body in which four inclined planes, designated by the reference numerals 10a, 10b, 10c and 10d respectively, protrude from an overlying cylindrical portion and slope downward; said body has, after a cylindrical portion, a conical end 9a; in any case, it is clarified that a conical surface might equally be provided instead of the four inclined planes, and that likewise four inclined planes arranged consecutively to the planes such as 10a might be provided instead of the conical end 9a.
  • An abutment disk 12 whose function will be clarified hereinafter, is monolithically associated with the main body of the slider 9, with the segment 11 interposed; two diametrically opposite stems 13 and 14 for supporting eyes 13a, 14a for coupling to hooks of a lifting means protrude monolithically from said disk.
  • a stem 15 also protrudes monolithically from the disk 12 and is inserted, at its upper end, in a cavity 16 formed in a gusset 16a that connects the spokes 7a, 8b rigidly coupled to the upper flange 1, and is adapted to make contact, during the operating steps described hereinafter, with an actuation cylinder 16b, which is associated by threaded coupling with the wall of the cavity 16.
  • the reference numeral 17 generally designates the lower flange, which comprises an outer ring 17a and an inner ring 17b, which are connected by a flat plate 17c in the presence of reinforcement ribbing, and is provided with spokes such as 17d for monolithic connection to a central hub 18, which is adapted to mate with the hub 4 at the end of the column 3: the particular shape of the inner ring 17b constitutes an engagement means which will be described hereinafter.
  • the reel according to the invention comprises four curved panels 19, 20, 21, 22, which are adapted to form, when arranged side by side, a cylindrical surface on which a coil 23 can be wound.
  • the curved panel 19 is provided with a central rib 19a, which is monolithically connected thereto, fits between the spokes 5a and 5b and is pivoted thereto at 19b, with the tab 19c, which is adapted to make contact with the abutment disk 12 of the slider 9, and with jaws 19d, 19e welded thereto; such jaws support a wheel 19f, which is adapted to make contact with the inclined plane 10a and with the conical end 9a of the slider 9; at its lower end, the curved panel 19 has a ring portion 19g, whose cross-section is complementary to the cross-section of the inner ring 17b of the lower flange, so as to engage it following approach in a radial direction.
  • the curved panel 19 is also noted that it is provided with a longitudinal groove 19h at the radial openings 1e on the flange 1 and 17e of the flange 17, so as to allow the passage of straps for closing the coil of wire.
  • the lifting means are activated and cause the upward sliding of the slider 9 on the column 3, with consequent movement of the wheels such as 19f, which abandon the cylindrical portion on which they rest and slide on the inclined planes such as 10a: this produces an inward rotation of the curved panels such as 19, caused by the energy accumulated in the coil of wire, which in this manner is gradually discharged until it is substantially eliminated when the situation shown in Figure 6 is reached, i.e., when the wheels such as 19f have covered the entire length of the inclined planes such as 10a.
  • the wheels such as 19f make contact with the conical end 9a, consequently allowing the curved panels such as 19 to perform a further inward rotation up to the position in which the abutment disk 12 makes contact with the tabs such as 19c; this contact determines a final portion of the rotation of the curved panels, which is allowed by the end of contact between the wheels such as 19f and the conical end 9a and places said curved panels in the position in which they are fully disengaged from the lower flange 17, shown in Figure 7.
  • the slider 9 In its further upward motion, the slider 9 carries with it the entire reel, with the only exception of the lower flange 17, which at this point is separate from the rest, as shown in Figure 8, and remains on the ground with the coil of wire rested on it, ready for removal.
  • the cylinder 16b is thus returned to its seat and screwed in, producing a downward thrust on the stem 15 until the slider 9 connected thereto reaches the stroke limiting position which attains, by acting on the wheels such as 19f, the intended position in which the curved panels are fully open, with the wheels such as 19f resting on the cylindrical portion of the slider, and the lower flange 17 is engaged.
  • the described invention is susceptible of numerous modifications and variations, all of which are within the scope of the inventive concept; thus, for example, the number of curved panels can advantageously vary between three and six, and the slider 9 may comprise only inclined planes such as 10a, the end being cylindrical and having such a length as to allow the curved panels to perform the final movement determined by the contact of the corresponding tabs such as 19c with the abutment disk 12; the disk 12 can further be replaced with a plurality of abutments at the tabs of the curved panels.
  • wheels such as 19f might be connected to the slider 9, while the inclined planes meant to make contact with them might be rigidly coupled to the corresponding curved panels.
