Definitions

  • This invention concerns a plant to form and for the heat treatment of rolled products in coils or compact wound bundles.
  • the plant of the invention has the purpose of providing a line for the controlled cooling of wire rod and long rolled products.
  • such types of rolled products may be in the form of coils spread out along a roller conveyor line or in the form of already formed compact wound bundles.
  • the cooling conveyor of the invention may perform the cooling to suit the required properties of the end product.
  • the known art envisages the separate treatment of formed wound bundles and of coils spread out along a conveyor line.
  • the rolled product undergoes controlled cooling only in the latter form, namely in the form of coils but not in the form of packages or wound bundles.
  • FR-A-1.383.950 discloses a station for the collection of loose coils and the formation of wound bundles downstream from a conveyor belt; such belt is not described in detail, nor is the possibility of a double use for coils and wound bundles envisaged.
  • FR-A-2.010.428 discloses a cooling plant in which the coil-forming headstock can be moved on a carriage in the direction of the cooling belt.
  • This patent includes embodiments to cool vertical coils or horizontal coils and dwells on conveyor chains in particular. It does not envisage the conveying and cooling of pre-formed bundles.
  • FR-A-2.297.097 concerns methods for cooling loose coils with jets of air.
  • FR-A-2.344.636 discloses a cooling conveyor belt conformed with an inclined plane and able to rotate about its own centre, being intended to cool loose coils.
  • DE-A-1.652.999 discloses a tunnel conveyor for vertical coils with the formation of bundles at its end.
  • US-A-4,320,646 comprises a conveyor having two paths, long or short as required, for horizontal loose coils, with the formation of bundles at its end.
  • EP-A-0060227, EP-A-0069616 and WO-A-83/00646 concern essentially means to blow a cooling fluid (air and/or water), with coils being conveyed horizontally.
  • DE-A-1.214.635 discloses a cooling conveyor belt for coils deposited horizontally by a coil-forming headstock of a known type with a vertical axis.
  • This invention dwells in particular on the method of depositing, the coils and, to be more exact, on the method of geometrically superimposing the coils deposited subsequently, the coil-forming headstock being capable of being displaced sideways for this purpose.
  • the formation and cooling of wound bundles are not provided for.
  • Patent FR-A-1.531.429 discloses an endless conveyor for bundles of rolled products.
  • the plant provides for a station to wind the rolled products, a station to cool the bundles thus formed and a discharge station.
  • the patent provides for the cooling only of wound bundles and not of loose coils.
  • a coil-forming headstock fitted, together with a winding machine, to a movable carriage cooperates initially with a cooling conveyor, which may be curved or straight, downstream from a conveyor line.
  • a cooling conveyor which may be curved or straight, downstream from a conveyor line.
  • Such coil-forming headstock and such winding machine can be of any required known type.
  • the invention envisages that the carriage is moved crosswise to the cooling path in such a way as to bring the coil-forming headstock or alternatively the winding machine into a position to cooperate with the cooling path itself.
  • the coil-forming headstock When the coil-forming headstock has been brought to coincide with the beginning of the cooling path, the latter can cooperate with the coils being formed by such headstock.
  • the coils are taken along the cooling conveyor and undergo treatment on the same.
  • a bundle-forming pit within which the coils are made to drop so as to form wound bundles of wire.
  • the bundles thus formed are withdrawn as soon as they are complete.
  • a second method for operation of such embodiment consists in putting the winding machine, fitted to the carriage together with the coil-forming headstock, so as to coincide with the beginning of the cooling conveyor.
  • the winding machine forms packages or wound bundles, which are deposited on the cooling conveyor and then undergo a controlled cooling treatment according to the required methods.
  • cooling can be performed by means of air jets or other fluids, or by controlled hoods positioned above the roller conveyor line and possibly capable of being raised, or merely with natural cooling in the air.
  • Bundles thus withdrawn and also bundles formed from spread coils can be sent as required to separate usage lines or to one and the same usage line.
  • a stationary coil-forming headstock is provided which is located so as to coincide with the inlet of the cooling conveyor.
  • Winding machines preferably of a vertical type, are situated at a position near that of the coil-forming headstock and preferably alongside the cooling conveyor.
  • the coil-forming headstock is not used and the rolled product is sent to the neighbouring winding machines, which can be one or more in number.
  • the wound bundles are directed by the system described earlier or by another equivalent system.
  • wire in spread coils are collected with the methods described earlier, for instance by means of a pit to form wound bundles.
  • a plantto cool wound bundles and coils bears the reference number 10.
  • a line 11 to convey rolled products coming from a rolling train which is not shown here but is located to the right of the figure.
  • the carriage 12 can run on rails or guides 13 or other equivalent means and bears a winding machine 14 and also a headstock 15 to form coils.
  • the winding machine 14 is of a type with a vertical axis, whereas the headstock 15 to form coils has a horizontal ortilted axis.
  • a cooling roller conveyor 16 is located immediately downstream from the carriage 12 and in this case comprises a spiral section 116 and a subsequent straight section 216.
  • the spiral section 116 has the task of raising the bundles and coils for their successive separation with a fall at the end of the conveyor 16 itself and also enables space to be saved.
  • the conveyor 16 can also be envisaged as being of a straight or curved type or as being formed possibly of several segments and as having a desired length. Such parameters depend on the specific features of the plant.
  • a switching station 17 is positioned at the end of the cooling conveyor 16. In this switching station 17 the wound bundles 25 already formed and cooled along the cooling conveyor 16 are switched or the coils spread out on the conveyor 16 are possibly collected into wound bundles.
  • the carriage 12 When wound bundles 25 are employed, the carriage 12 is positioned in a position offset upwards and shown with lines of dashes in the figure; in this way the winding machine 14 is brought so as to coincide with the line 11 that feeds the rolled products.
  • the winding machine 14 discharges the wound bundles 25 of rolled product still hot onto the cooling conveyor 16.
  • Thrust means 18, which is this case include jack means but could be of any type, at the end of the cooling conveyor 16 in correspondence with the switching station 17 thrust the wound bundles 25 sideways and cause them to be withdrawn on withdrawal means 19, which can be of any known type.
  • Such means 19 can include forks, jaws, levers, chutes or other means able to engage the bundles 25 and to withdraw them from the cooling conveyor 16.
  • the means 19 deliver the bundles 25 to manipulator means 20 which are able to arrange the bundles 25 with an orientation suitable for withdrawal.
  • manipulator means 20 too are known in themselves.
  • the manipulator means 20 convey the bundles 25 towards a final collection station bearing the reference number 21 in the figure.
  • coils spread out along the cooling conveyor 16 are employed, they are formed by the coil-forming headstock 15, which is moved so as to coincide with the rolling line 11; the position of the carriage 12 is that shown with continuous lines in Fig. 1.
  • the coils formed by the coil-forming headstock 15 are arranged thereafter on the cooling conveyor 16 and thus conveyed and cooled up to the end of the conveyor 16.
  • Such bundles 25 are then withdrawn at 21 by conveyor means 23.
  • the thrust means 18 are not actuated, the coils being switched by falling into the coil collection pit 22.
  • the plant shown can serve not only to cool and convey the wound bundles 25 already formed but also to cool and convey coils, which are formed into bundles 25 at the end of the conveyor 16.
  • the plant obtains in this way a great simplification of the path followed, a working economy and also a considerable versatility since cooling can be performed also on pre-formed bundles 25, a step which cannot be carried out in the known art.
  • Fig. 2 shows a variant of the invention in which the rolling line has two branches, 111 for delivery to a coil-forming headstock 15 and 211 for delivery to a winding unit 24.
  • This unit 24 in this case comprises two winding machines 14 of a vertical type and is located at the side of the cooling conveyor 16. Wound bundles 25 can be seen on the roller conveyor 16.
  • the coils spread by the headstock 15 on the conveyor 16 are cooled on the cooling conveyor 16 and are sent lastly to a switching station which is not shown but is analogous to the station 17 of Fig. 1.
  • the rolled product coming from the rolling line 11 is channelled with known means along the branch 211 and taken to the winding machine 14.
  • the machines 14 are of a type with vertical pins.
