Definitions

  • the object of the present invention is a coiler for metallic rolled or drawn wire and/or rods with secure hooking, according to the characteristics of the main claim.
  • the winding installation and/or the production line of the material containing said coiler is also part of this invention.
  • Wires and/or rods are understood both in the strictest sense as well as in the sense of rods, namely material with a large diameter and/or profiles and/or sections with a varying form and shape that is to be wound in coils by means of a flanged rotating mandrel or reel, said coils then being removed and transferred to a binder machine.
  • Said wire and/or rods and/or profile and/or section can produced in a continuous or non-continuous way at various speeds both in rolling and drawing installations, but preferably, although not exclusively in continuous hot rolling installations
  • material or material to be wound is understood in this description as any type of elongated material as mentioned above.
  • the wire or rod is sectioned into determined lengths corresponding to a coil and is then redirected for winding on one coiler unit or on another, so that when a coiler winds the wire to form a coil, the other discharges the coil already completed.
  • the introduction and clamping of the wire occurs by means of a guide channel capable of forming at least the first turn of the coil or a series of first turns.
  • US3945585 of 23 March 1976 provides a channel for clamping and formation of the first turns of the coil around the mandrel by means of a bell type element that advances and retracts (10, 6, 11) precisely forming an entrance and clamping channel of the wire during the winding of the first turns.
  • US-4664329 (Pali-Essex - 12 May 1987) provides a wire guide and clamping system for the formation of the coil by means of a strip that winds the coil and simultaneously pulls it thus making the winding mandrel rotate, in this way the wire is continuously forced to wind itself compactly.
  • EP1126934 and EP1126935 (Danieli ) also describe wire guide systems for the start of the formation of the coil similar to Morgan.
  • a dynamic clamping system is provided with a pincer function of the wire that is then loosened (withdrawal in the DEMAG system) to allow the extraction of the coil from the winding mandrel at the end of winding.
  • the clamping system of the first turns of the wire is executed as in US3945585 (DEMAG) but with the movement of the entire base flange which moves along the mandrel making the wire intake channel deeper in order to allow the embedding of certain turns, to then be withdrawn covering only a part of the first turn when the return winding that forms the second layer is carried out.
  • the solution is structurally very complex and also expensive in terms of the movement mechanisms required for a large mass such as the base flange.
  • the guide system having a fixed arched channel without rotating elements, presents the inconvenience of producing considerable friction and since the wire to be wound is still hot as it originates from hot rolling, it is notably very flexible and therefore could snarl and cause tangling, forcing the stoppage of the winding installation and as a consequence the entire production line.
  • the mandrel of the coiler must rotate at a peripheral speed slightly higher than that of the advancement of the material so that the latter is placed in slight tension in order to favour correct and compact winding.
  • US3527077A also refers to coiling rod in which: " to assist in holding the inserted leading edge of the rod R, in the groove 136, serrations can be provided on the shoulder 118 and the inner periphery of the radial end face of the wall 126, as depitcted in Fig.3A) :"
  • an "U-grooved"sliding guide element 242 in prosecution of a free rotating bar clamping-roller (210 - Fig.3 particular: 3A-3A Fig.3 in connection with Fig.3A).
  • US3472461A discloses a " Method and apparatus for anchoring one end of the continuous advancing material " in which on a "carrier groove 12" of a “ winding head 10 " the "leading end 13 of the material being wound” is clamped by the “roller means (14) in the shape of sector ".
  • the main aim of this invention is to supply a much more effective and suitable system to guide and hook automatically the material to be wound without dynamic pincer systems and to limit to a minimum the damage to the wire when introduced.
  • the grip jaw is substantially formed:
  • the invention also provides the use of interchangeable teeth allowing the coiler to be adapted easily to different types of wire or rods or sections and also different profiles, as otherwise it would also be necessary to change the winding machine, since the same channel would not be suitable for adapting to any form or profile of material to be wound.
  • FIG.6 represents a schematic view of the helical grip ribbings (2531) on the surface of the mandrel opposite the teeth (252), which decisively improves the grip and prevents the wire from escaping due to the internal traction of the helical grooves
  • Figure 7 represents in a more enlarged view, the left part of Figure 3 to show in greater detail the pressing system with rollers (234, 2341) that progressively push and maintain the bar between said clamping teeth (252) and the mandrel (253).
  • Figure 8 represents the enlarged right side of Figure 3 to show, not only the recessed arched form (2520) of the tooth (252) toward the mandrel, but also its inclined trapezoidal form towards the exterior (2521) in order to be tapered and prevent its height from exceeding the diameter of the bar (T1) in order to avoid obstructing the formation of the turns interposing between one turn and another, namely between the first row and the third row of turns of the coils.
  • the coil can easily be extracted axially when completed and the minimum space left by the toothing of the teeth (252) does not substantially influence its form, dimension or weight.
  • the winding unit includes a coiler (2) associated to motorization means (M, M1) for the rotation of its mandrel (25) and semicircular pressure means in the form of an open jaw (233) with pressure rollers (234, 2341) on an arm (232) that is hinged (230) and activated by means of a return lever (231) with a piston (23) articulated at the base (20) of the coiler (2).
  • M, M1 motorization means
  • semicircular pressure means in the form of an open jaw (233) with pressure rollers (234, 2341) on an arm (232) that is hinged (230) and activated by means of a return lever (231) with a piston (23) articulated at the base (20) of the coiler (2).
  • the jaw with rollers (232,233), open towards the exterior can be raised and lowered to press over a lower base flange (252) of the winding mandrel (253), that according to the invention presents the rim of teeth for holding material (252) and thus against these teeth.
  • the entrance of the wire is favoured by a funnel-shaped entry of the entrance side (235) of the jaw (233) that immediately presents a first pressure roller (234) that is more effective than other entrance solutions.
  • the articulation of the pressure jaw (232, ..., 32) is such that it is possible to transfer it from an engagement position of its rollers (234, 2340, 2341) against the rim of teeth (252), to a substantially distanced position, outside the material winding area, (to allow the approach of other series of opposite rollers (not illustrated) suitable for maintaining the winding of the last turns when the wire is not held in tension by the drive means, once the coil is completed, and this allows a grip and extraction of the coil without loosening the turns themselves).
  • the winding mandrel (253) rotates at a variable speed by means of the motor system (M, M1), placed downstream to the side of the jaw with rollers (233, 234). In this way the winding system is freed from any obstruction thus allowing other orthogonal counter-rollers to approach oppositely after engagement for maintenance of unwinding in the final winding phases.
  • the rotation speed is calculated in such a way that there is always the same peripheral speed corresponding to that of the linear advancement of the wire, the assembly being controlled by an electronic control unit distanced from the safety system so as not to be influenced by the temperatures that develop in the area of winding or coiling.
  • the mandrel consists of retractable sectors that in cooperation with lower and internal movement (255, 256) are withdrawn when the coil has been completed, being arranged conically in order to facilitate the upward extraction of the finished coil and the release of the wire head previously clamped.
  • Crosswise grooves (2510) are provided on the base flange (251) to allow the seizing of the coil with opposite gripper jaws for the extraction of the coil by means of lifting, said flange being integrated into the structure of the mandrel itself (2530) and therefore having a simplified structure without complex movement mechanisms.
  • mandrel (2530) is formed, as mentioned (although not shown) by four hinged sectors at the base of the flange (251), which tighten for the extraction and are also associated to a mechanism (not shown of rotation of the corresponding four upper flange sectors (254) that by means of the axis (255), and the movement devices below (257), of the unit (256) are raised like the petals of a flower and allow therefore the upward extraction of the coil (petals closed)).
  • a wire guide trolley (1) Frontally to the coiler (2) there is a wire guide trolley (1) that comprises a horizontal guide (121) of the base (10) orthogonal to the medium advancing line of the material (X-X) on which a slide (11) is mounted with an auger column (111).
  • the slide (11) therefore moves alternately on command (not shown) in order to move the auger column (11-111) according to the axis (Y-Y) to always maintain it on course, namely on the tangent to the coil winding diameter of the mandrel (253), that noticeably increases progressively with the increase of the diameter of the coil in winding.
  • the auger column (11-111) moves vertically in a reciprocating movement (therefore alternately) a slide (110) that is thus raised and lowered according to the orthogonal axis (Z-Z) to form progressively the forward and return turn of the coil in winding.
  • the plate of the slide that is moved vertically (110), by the auger column (111) for left or right rotation by means of a known electromotor (for example, stepping controlled) and by a suitable electronic control unit that checks all the movements of the winding device, supports with hinges the end of a support or oscillating pilot bar (1131) that carries the material to be wound such as wire or rod or bar from the rolling mill with a suitable cutting system (not shown).
  • a support or oscillating pilot bar (1131) that carries the material to be wound such as wire or rod or bar from the rolling mill with a suitable cutting system (not shown).
  • Said guide is hinged (1130) to said plate (110) to allow reciprocal inclination for the formation of the turns in the coiler (25).
  • the pilot bar support (11341) comprises the guide channel of the material (113) that presents a wire guide entrance extension (1130).
  • this guide channel (1130-113) there is an oscillating wire guide extension (112) which oscillates on a pin (1120) to keep the material in winding always according to the inclination angle, upwards once (with the wire guide extension in a downward movement) and downwards once (with the wire guide extension in an upward movement) so that the inclination always corresponds to the winding inclination angle of the wire wound on a bobbin that it is never orthogonal.
  • the end of this oscillating wire-guide extension (112) can advantageously be interchangeable to adapt to the form of the type of material to be wound.
  • the advancing material thus exits the wire guide extension (112) and is introduced into the entry (235) of the jaw with guide rollers (233-234) where the material (T1) is progressively pressed by the rollers (234,2341) between the rim of teeth (252) and the external surface of the mandrel (253) clamping the material (T1) in a forced way.
  • the first entry roller is slightly recessed (234-2340) in such a way as to aid the entrance of the material (T1), then the successive rollers are cylindrical (2341) to press the material (T1) definitively between the rim of teeth (252) and the external surface of the mandrel (253) until hitting the bottom of the base flange (251).
  • the internal recessed arched form of the teeth (2520) aids the hooking of the material and hinders the escape of the material by favouring the housing.
  • the external trapezoidal form of the teeth (2520.252) allows improved housing of the following turns of the coil without hampering their staggered formation.
  • idle press rollers are mounted (233) on bearings (2331-2332) which in an overhanging way carry the axis (2342) of the rollers 234 that for this purpose have a flared inclined flanging (2342) that fits with the inclined trapezoidal surface (2521) of the teeth (252).
  • This improved support aids the controlled penetration in a precise way of the material to be wound.
  • the roller overhanging toward the mandrel, moreover, allows its maximum approach to the mandrel with an improved wire guide.
  • teeth (252), as mentioned earlier, are interchangeable with other suitable forms in order to adapt to the different forms and dimensions of the material to be wound.
  • press rollers (234) can obviously vary most.
  • the mandrel withdraws in its diameter assuming a conical form and consequently the clamped bar of the first winding turn is freed and therefore the upward extraction of the coil is aided.
  • the internal surface of said teeth (252) is ribbed and/or toothed and/or knurled. In this way an improved grip as on the opposite surface (2520) is guaranteed.
  • the entire coiler is housed in a box made from sheet metal and suitable videocameras control its functioning from a remote television control room and it is associated to computerized means for the total control of functioning.
  • the coiler has a vertical axis (2) and is housed in an armour-plated box made from sheet metal closed with a safety access door that cannot be opened during functioning and that comprises an upper opening in order to be able to lower coil withdrawal means from above to be able to carry out extraction from above, and control means and sensors and a videocamera are provided in said box for the control and checking of the regular progression of the work by means of a cabin with remote control.
  • a rolling plant comprising at least two winding lines downstream, with a continuous cutting system and deviation on one or the other, parallel with identical coilers having a vertical axis (2) between which is interposed a vertical transfer extractor with a column with a rotary arm for extracting alternately from above the completed coil from a coiler while the other is forming a coil, and rotationally transfers it downstream directly in a coil binder machine.
