Definitions

  • ABSTRACT Helicoidally wound wire coming hot from a looping machine is fed axially onto a vibrating elbow shaped mandrel with a slightly downwardly sloping entrance leg and a vertically decending exit leg.
  • the turns of the looped wire leaving the mandrel are deposited on a verticlly movable annular platform, surrounding a cylindrical core, which is periodically raised to compress a number of turns aginst lugs swung in laterally between the mandrel and the core.
  • a cutting and tying device binds the compressed turns into a coil which, upon a lowering of the core, is laterally discharged from the platform.
  • Our present invention relates to a device for conveying loose turns of wire which has been helicoidally wound in a looping machine after coming hot from a rolling mill.
  • the general object of our present invention is to provide an improved conveying device establishing an elongate path over which the loosely wound wire passes in a controlled atmosphere with avoidance of all contact between its loops.
  • a more particular object is to provide a device of this nature having means for bundling a certain number of turns of the looped wire into coils and removing these coils from the treatment path without interfering with the continuous formation of fresh wire loops traveling over the same path.
  • a preferably elbowshaped mandrel with a generally horizontal entrance leg confronting a looping machine and with a substantially vertically descending exit leg overhanging a recovery station, the mandrel being equipped with a vibrator maintaining it in an oscillatory condition which facilitates the advance of the loops therealong.
  • the entrance leg of the mandrel is slightly inclined in a downward direction and has a diameter' about equal to the inner loop diameter, decreasing somewhat at the exit leg. This insures the maintenance of a relatively wide average spacing along the downwardly sloping mandrel portion between successive loops which, owing to the resiliency of the wire material (e.g., steel), tend to move'intermittently over the surface of the vibrating mandrel with alternate contractions and expansions of the helix.
  • the wire material e.g., steel
  • the wire is fed to the looping machine at such a rate (compared with the speed of rotation of its eccentric outlet) that the emerging helix turns about the axis of rotation besides advancing along that axis, then the helix will come to rest on the entrance leg of the mandrel at points of contact progressively moving along the turns to insure uniform exposure.
  • the mandrel is spacedly surrounded by a loop-guiding tube also serving as a treatment chamber.
  • a loop-guiding tube also serving as a treatment chamber.
  • the environment of the wire loops within the tube may be controlled to provide a desired tempering effect, as by heating the front part of the sloping tube portion to maintain an approximately constant temperature level and then quenching the hot metal by a water spray in an intermediate zone of that portion, followed by gradual cooling of the wire in the rear part thereof.
  • the treatment chamber may be filled with an inert gas to prevent scaling of wire of high-grade steel or the like.
  • the recovery station adjoining the exit leg of the mandrel comprises, in accordance with a further feature of our invention, an annular platform centered on a cylindrical core and vertically slidable therealong, the
  • the core being of substantially the same diameter as the exit leg of the mandrel with which it is coaxially aligned. Normally, this platform rests near the bottom of the core to receive a multiplicity of wire turns accumulating between the core and a sleeve spacedly surrounding same.
  • one or more normally withdrawn supporting elements are extended into the path of the wire helix at the lower end of the mandrel for temporarily retaining subsequently arriving loops.
  • the supporting elements hold down the top of the stack which is thereby transformed into a compressed coil.
  • the coil thus produced may be severed from the following length of wire and tied,.preferably automatically, prior to removal from the recovery station.
  • FIG. 1 is a side -elevational view, partly in section, of a treating and stacking device embodying our invention.
  • FIG. 2 is a fragmentary view similar to part of FIG. 1 but showing the assembly in a different operating position.
  • FIG. 1 shows a pair of counterrotating transport rollers 1 feeding a freshly rolled wire 2 to a looping machine 3 which may be of conventional construction but, advantageously, is of the type disclosed in commonly owned copending application Ser. No. 196,962, filed by one of us, Horst-Dieter Hirschfelder, on Nov. 9, 1971.
  • a machine comprises a fixed base 31 and a rotary head 32 centered on a horizontal axis and drive by a motor 37, an eccentric wire-dispensing duct 33 passing through that head and terminating at an offaxial location where the wire is gripped between a revolving roller 34 and a frusto-conical central disk 35 held stationary by a planetary-gear train 36 having a sun gear rigid with the base 31.
  • a tubular mandrel 5 having a substantially horizontal, slightly downwardly sloping entrance leg 7 and a vertical exit leg 8.
  • the left-hand end of leg 7, confronting the rotor 32 of looping machine 3, is cantilevered on a stationary supporting shaft 9 integral with disk 35.
  • This arrangement facilitates the oscillation of mandrel 5 by means of a vibrator 10 attached to the free lower end of leg 8.
  • the front end of this tube carries a heating coil 19 designed to prevent a sharp drop in the wire temperature until the helix reaches an intermediate zone where one or more sprinklers 20 spray water upon its turns.
  • the loops 4 are transferred by gravity to a cylindrical core 16 which is spacedly surrounded by a sleeve 6 aligned with the bottom end of tube 11.
  • a plurality of lugs 12 are hinged to the tube 11 so as to be swingable (e.g., electromagnetically) into a coplanar position, illustrated in FIG. 2, under the control of programmer 20.
  • the desce'nding loops accummulate on a platform constituted by a pressure ring 13 which may be raised from its normal position (FIG. 1) into an elevated position (FIG. 2)
  • the core 16 and the sleeve 6 are likewise vertically reciprocable, with the aid of a jack 15, in response to a signal from the programmer.
  • a number of loops 4 are allowed to accummulate on the pressure ring 13 while the lugs 12 are withdrawn so as not to interfere with the descent of the loops into the space between sleeve 6 and core 16.
  • the lugs are swung up into a plane just below the bottom end of mandrel 8, whereupon jacks 14 are operated to raise the ring 13 into the position of FIG. 2, thereby compressing the stacked loops into a coil 17.
  • a cutting and tying device 18, which may be one of several such devices peripherally spaced about the core 16, then goes into action while the core 16 and the sleeve 6 are lowered to facilitate the operation of that device and to permit the lateral discharge of the bundled coil.
  • Ring 13 may have surface grooves or gaps giving access to the tying tools of mechanism 18.
  • a device for conveying loose turns of helicoidally wound wire coming from a looping machine comprismg:
  • a mandrel with an essentially horizontal entrance leg supported at one end and a substantially vertically descending exit leg terminating in a free end, said entrance leg being positioned to receive the oncoming wire loops via its supported end;
  • said recovery means comprises a cylindrical core of a diameter substantially equaling that of said exit leg and aligned therewith, an annular platform surrounding said core and slidable therealong, and normally withdrawn support means positionable adjacent the lower end of said exit leg for temporarily retaining descending wire loops and resisting the rise of loops stacked on said core upon a raising of said platform to convert a plurality of stacked loops thereon into a compressed coil.
  • said support means comprises a plurality of peripherally spaced lugs swingable into a horizontal plane underneath said exit leg.
  • said recovery means comprises cutting and tying means for said coil at a level below said lower end but above a normal level of said platform, the latter being elevatable to a raised level just below said cutting and tying means.
