Definitions

  • This invention concerns an automated system to package and discharge rolls of metallic wire wound on reels.
  • the invention concerns a system that provides full automation of the operation of winding the metallic wire and also full automation of the handling of reels thus packaged up to the stage of discharge of the wound rolls of wire.
  • the system of the invention is applied downstream of the plants which carry out hot or cold drawing or rolling of metallic wire.
  • wire is to be understood in its widest meaning as covering wire products having a round, oval, three-lobed, hexagonal, rectangular, square, etc. section.
  • the system can be employed also in plants producing other wire materials.
  • the roll of wire is discharged from the reel and the reel is re-assembled so that it can be returned to the working cycle.
  • Document CH-A-618141 discloses an automated system to package and remove rolls of flexible tube, which comprises a winding machine with automated systems to start-up and end the winding of a reel with a three-positional rotary platform, an auxiliary device for tying the reel and a device to clamp and dismantle a reel positioned on the winding machine.
  • the device disclose in CH-A-618141 is suitable for light weights but not for weights such as that of a reel of metallic wire, which may reach 1500 kgs. or more. From this point of view the automated system disclosed, such as the apparatus to tie and dismantle the reels, are not workable in a device which has to handle reels of metallic wire.
  • the present applicant has the purpose of overcoming the problems of the state of the art by providing a fully automated system to package and discharge rolls of metallic wire wound on reels.
  • the system according to the invention provides for the preferred use, for the winding, of reels which can be dismantled, namely of reels formed in such a way that the wound roll of wire can be removed by means of the axial withdrawal of one of the two lateral flanges of the reels.
  • the system of the invention employs a fully automated winding machine, namely a machine which carries out by automatic methods all the wire winding operations, including the operations linked to the start-up and ending of the packaging of every reel being processed.
  • a fully automated winding machine of the type employed in this invention is the subject of a parallel patent application in the name of the present applicant.
  • the automatic winding machine is equipped with a three-positional rotary platform, the first position being used for packaging the reel, the second for tying the rolls of wire and the third for removal of the reel.
  • the reel after being packaged with wire in the first position, passes on to the second position where the wound roll of wire is completely tied by means of an appropriate apparatus.
  • the insertion and fixture of the actual tying elements can be done by hand or by a suitable automatic device. Thereafter the reel thus tied passes on to the third position, where it is removed by a handling device, which is an automatic device located downstream of the winding machine and suitable to cooperate in succession with two other stations, which open or dismantle the reel and discharge the wound roll of wire respectively.
  • a handling device which is an automatic device located downstream of the winding machine and suitable to cooperate in succession with two other stations, which open or dismantle the reel and discharge the wound roll of wire respectively.
  • the handling device By passing along the path in the opposite direction, the handling device re-assembles the reel and takes it back to the third position on the rotary platform.
  • the cycle requires for its fulfilment only three reels, which exchange their functions by rotating together with the platform to the three working positions provided.
  • an automated system 10 comprises a fully automatic winding machine 11 located downstream of a plant to draw or roll metallic wire.
  • This winding machine winds rolls of wire onto reels 12 which can be dismantled (and which are shown diagrammatically with circles in Fig.1), the reels being arranged with their axes vertical on a three-positional rotary platform 13.
  • Position A on the platform is the station where the reel 12 is rotated by a suitable headstock and tailstock 14 so as to take up onto its body the metallic wire fed from upstream processes.
  • Position B is the station where the packaged reel 12 is tied by an auxiliary device for the tying operation 15.
  • Position C is the station where the reel 12 is removed by means of an automatic handling device 16.
  • the winding machine 11 on its side towards the feed of metallic wire is equipped with an automatic apparatus, referenced with 17, for the start-up and ending of the process of packaging a reel 12 which can be dismantled.
  • this automatic apparatus engages the end of the wire and positions it suitably on the reel located in position A and then permits the start-up of winding.
  • the automatic apparatus shears the end of the wire, bends it suitably and positions it on a retaining support on the reel 12; it then arranges to transfer the sheared end of the wire onto the devices which start up the winding.
  • the auxiliary device 15 for the tying operation is shown in position B and consists substantially of a unit 18 to engage and rotate the reel and of a unit 19 to lift the reel.
  • the engagement and rotation unit 18 is a control box 20 bearing terminally a mandrel 21 and a gripper 22. In its inactive position this unit 18 is lifted from the reel 12; when a reel 12 reaches the tying station, the control box 20 is lowered automatically to bring the mandrel 21 axially so as to correspond with an upper flange 29 of the reel 12.
  • the lifting unit 19 is then actuated and cooperates through an opening 23 in the platform 13 with a lower flange 30 of the reel 12, thus lifting the reel 12 and aligning it with the mandrel 21.
  • the gripper 22 is actuated so as to fix itself on one of the spokes of the upper flange 29 of the reel 12, thus putting the reel 12 in a condition to be able to rotate.
  • Rotation of the reel 12 takes place by actuation of the mandrel 21 by suitable control means in the control box 20. This rotation is required to enable the elements tying the roll of wire to be inserted within the reel 12, normally at a plurality of points at various angles between them, for instance four points at 90° to each other.
  • the tying operation can also be carried out by an appropriately equipped automatic device positioned according to the arrow F.
  • the reel 12 In position C the reel 12 is in the station for its removal from the winding machine 11 and for its transfer to subsequent processing stations, which are a station in position D for the dismantling of a reel that can be dismantled and a station in position E for discharge of the roll of wire wound on the reel 12.
  • Movement from position C to positions D and E is carried out by the automatic handling device 16, which is located at a stationary position downstream of the winding machine 11 and comprises a support structure 24 for a movable arm 25.
  • the movable arm 25 is capable of a rotary movement 26 about the axis of the support structure 24 and of a straight vertical movement according to the arrows 27.
  • a handling device of the type shown according to this invention is the subject of a parallel patent application in the name of the present applicant.
  • the movable arm 25 bears on its lower side an engagement device consisting essentially of a gripper unit 28 able to close and secure itself to the upper flange 29 of the reel 12.
  • the handling device 16 takes the reel 12 from position C, lifts it according to the arrows 27 and rotates according to the arrows 26, thus bringing the arm 25 to position D, which is the station for dismantling, or opening, the reel 12.
  • Position D is a stationary station equipped with a clamping device 31, which consists essentially of a pair of engagement arms 32 that can be retracted by being rotated.
  • Figs.1 and 2 show with lines of dashes (32') the inactive positions of the engagement arms 32 .
  • the lower flange 30 is released from the reel 12 by the action of suitable means with which the handling device 16 or the reel dismantling station is equipped, depending on the structure of the reel 12. If, for instance, the reel 12 is of a type which can be dismantled by the action of external axial means, as disclosed in a patent application in the name of the present applicant, then the movable arm 25 itself may be equipped with such means to withdraw the lower flange 30 after the reel 12 has been engaged by the gripper unit 28.
  • the clamping device 31 is equipped with suitable means which during the step of release of the lower flange 30 control the unavoidable outward springing of the wire due to the coils of metallic wire having been held between the flanges 29-30 and to the very strong tensions built up during winding of the coils.
  • reel 12 If the reel 12 is of the type cited above, it itself will include means to hold the wound roll so that the reel 12 without its lower flange 30 can be removed from position D without the roll being released and falling on the ground.
  • Movement of the reel from the station in which it has been dismantled to the next discharge station in position E is also carried out by the movable arm 25 of the handling device 16.
  • collection means able to receive rolls of metallic wire referenced with 34 in Fig.2.
  • These collection means may be storage benches 35, as shown in Figs.1 and 2, or conveyor belts or roller conveyors or any other suitable means to receive and discharge thereafter the rolls 34 of metallic wire.
  • the means holding the roll 34 on the reel 12 are disabled at position E so that the rolls 34 can be released on the relative collection means 35.
  • the system 10 according to the invention therefore requires only three reels 12 during the winding and discharge of the wound roll 34 of wire, namely a first reel 12 for the actual winding process in position A, a second reel 12 being tied at position B and a third reel 12 for the removal step at position C.
  • the second reel can be tied at the same time and the third reel can be engaged, dismantled, re-assembled and re-positioned for use.
  • the system can also use reels which cannot be dismantled; in this case the dismantling station can be replaced or amalgamated with a device to feed automatically empty reels which cannot be dismantled, while the station to discharge the roll of wire can become a station for discharge of reels of wire which cannot be dismantled.
  • the handling device itself during its return from the discharge station of full reels can arrange to take, in cooperation with the reel feed device, an empty reel required to feed the winding machine.
