Definitions

  • This invention concerns a device to handle reels of metallic wire of the type described in the main claim.
  • the invention concerns a device able to engage and handle with automatic methods the reels wound with wire on winding machines with the purpose of obtaining the removal of the roll of wire wound on such reels.
  • the device according to the invention is installed advantageously downstream of machines that wind the metallic wire and upstream of the stations where the reels are dismantled and the rolls of wire are removed from the reels of a type that can be dismantled.
  • the device is therefore installed in plants performing the hot or cold drawing or rolling of metallic wire.
  • wire is to be understood in its widest meaning as covering products having a round, oval, three-lobed, square, rectangular, hexagonal, etc. section.
  • the reel thus dismantled has to be re-assembled so that it can be used again in the production cycle.
  • This offers a considerable saving as regards the cost of the overall number of reels employed, the space occupied owing to a great reduction in the intermediate storage areas, the circulation of the reels and other necessary materials as the working cycle can be limited to a short travel, and other advantages.
  • Document EP-A-0276651 provides for a programmable robot of a wire-guided or radio-controlled type to load and unload empty reels and full reels automatically onto and from wire winding machines. This document arranges for the reels which cannot be dismantled, to be conveyed by being supported from below with their axis horizontal.
  • Document DE-A-3627569 provides for a manipulator to handle reels with their axis horizontal.
  • the manipulator can move and cooperates with an overhead guide runway, so that the reel is suspended while travelling on the runway, thus entailing problems of the overhead space taken up and of the danger to the machine operators.
  • the present applicant has the purpose of overcoming the problems of the state of the art by providing a fully automatic device to handle reels of metallic wire.
  • the handling device is an automatic apparatus located downstream of a winding machine that winds metallic wire so as to cooperate with a station that removes rolls of wire produced on the winding machine.
  • the handling device is located advantageously in a stationary position in relation to the removal station and to the subsequent stations with which the device has to cooperate.
  • the subsequent stations are preferably a station to dismantle the reel and a station to remove the roll of wire wound on the reel.
  • the handling device can cooperate with other types of station and, if necessary, can be moved to various positions according to the requirements of the production cycle.
  • the reel handling device consists of a stationary structure that bears a movable assembly which performs the actual handling of the reels.
  • the movable assembly is capable of an alternating rotary movement about the axis of the stationary structure so as to be able to cover the areas of cooperation with the cited stations on its outward or return path.
  • It is also capable of an alternating straight movement along the axis of the stationary structure so as to be able to carry out at each station the operations required at that station.
  • the movable assembly is equipped with means to engage the reels, means able to cooperate with reels capable of being dismantled by withdrawing one of the flanges of those reels and also means to control the roll of metallic wire.
  • the movable assembly during its return travel from the cited stations towards the winding machine can also be used to re-assemble the reel dismantled beforehand and to take that reel back to the production cycle.
  • the device can also handle reels which cannot be dismantled; in this case the station to dismantle the reel can be replaced or be amalgamated with an automatic store that feeds empty reels, while the station that removes the rolls of wire will become a station for discharge of the reels full of wire.
  • the movable assembly During its return travel from the reel removal station the movable assembly will arrange to take from the empty reel store the reel required for positioning on the winding machine.
  • a reel handling device 10 comprises substantially a stationary structure 11 having a vertical development and bearing a movable arm 12.
  • the movable arm 12 is firmy secured to an outer sleeve 13 positioned coaxially with the stationary structure 11.
  • the outer sleeve 13 is connected in turn to an inner sleeve 14, which too is coaxial with the structure 11 and in relation to which the outer sleeve 13 can slide vertically by means of slider elements 15.
  • the movable arm 12 can therefore move vertically according to the arrow 16 and can pass from a lower position marked with continuous lines in Fig.1 to a higher position marked with lines of dashes in Fig.1 and viceversa.
  • the vertical movement of the arm 12 in the direction of the arrow 16 is obtained in this instance by a jack 17 secured at 18 to the inner sleeve 14.
  • the inner sleeve 14 can rotate through a full circle together with the outer sleeve 13 about the axis of the stationary structure 11 in the directions of the arrows 19. This rotation is made possible by rotary slider elements 20 and is actuated by a suitable motor 21 solidly fixed to the inner sleeve 14.
  • This motor 21 is advantageously, but not necessarily, a D.C. motor 22 required to control the gradients of acceleration and deceleration of speed in relation to the rotary motion of the arm 12.
  • the D.C. motor 22 drives, through a speed reduction unit 23, a gearwheel 24, which engages a stationary crown wheel 25 solidly fixed to the structure 11.
  • Fig.1 shows a vertical plate 26 integral with the inner sleeve 14; this plate 26 has the function of preventing shaking of the movable arm 12.
  • the plate 26 passes vertically through an opening 27 in the arm 12, which in its vertical travel in the direction of the arrow 16 is guided on both side of the plate 26 by suitable movement means, for instance rollers 28.
  • the movable arm 12 is equipped with reel engagement means 29 consisting in this case of a pair of grippers 30 able to oscillate about pivots 31.
  • the grippers 30 are suitably actuated by a pair of corresponding jacks 32 so as to engage an upper flange 33 of the reel handled by the device 10; the upper flange 33 is indicated with lines of dashes in Fig.1.
  • the movable arm 12 is also equipped with a means 39 to actuate release of the removable flange 33 of the reel 41 by acting in an axial direction, for instance, if the reel 41 being handled is of a type having a removable flange.
  • the means 39 in question is represented by a jack 34 and a rod 35, which can move axially so as to cooperate with coordinated release means within the reel.
  • the release actuation means 39 for the flange 33 will not be included or, if included, may be disarmed where the device 10 of the invention is handling reels which cannot be dismantled.
  • Fig.2 shows a view of part of the arm 12 along the line of the arrow 36.
  • a transverse plate 37 is connected to the arm 12 and has the purpose of cooperating in the retention and control of the roll of metallic wire 43 reached by the arm 12 being oriented when in the station 40 where the reel is dismantled.
  • the transverse plate 37 comprises suitable seatings 38 able to engage any clamping grippers included in that station 40.
  • the reel dismantling station 40 does not form part of the invention.
