BY R9 w Attorney 1 WIRE-LOOP STACKER 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.
It is generally desirable to subject such wire to a heat treatment (tempering or annealing) as it leaves the loop winder on its way to a stacking device. If this heat treatment is carried out on a conveyor grid over which the loops are spread prior to stacking, the crossover points of adjoining loops are not exposed to the same ambient temperature as the remainder of the wire so that nonuniformity of treatment and therefore of structure results. A
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.
These objects are realized, pursuant to the present invention, by the provision of 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.
Advantageously, 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. If 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.
According to another feature of our invention, the mandrel is spacedly surrounded by a loop-guiding tube also serving as a treatment chamber. Thus, 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
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. When a predetermined number of loops have been stacked in this space, 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. As the platform is raised, the supporting elements hold down the top of the stack which is thereby transformed into a compressed coil. At this point, with the core and its sleeve lowered to or beneath the level of the elevated platform or pressure ring, the coil thus produced may be severed from the following length of wire and tied,.preferably automatically, prior to removal from the recovery station.
The invention will be described in detail hereinafter with reference to the accompanying drawing in which:
FIG. 1 is a side -elevational view, partly in section, of a treating and stacking device embodying our invention; and
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. Such 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.
In accordance with the present invention, we provide 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 wire 2, emerging from the looping machine 3 loosely wound into helicoidal turns 4, envelops the mandrel 5 while advancing therealong in a treatment chamber formed by'a surrounding tube 11. 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. Upon reaching the lower end of leg 8, 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. At that bottom end 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)
by a plurality of hydraulic or pneumatic jacks 14 also controlled by the programmer 20. 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.
In operation, 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. Thereafter, 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.
After the discharge of the coil 17 just formed, the position of FIG. 1 is restored so that the loops meanwhile accumulating in somewhat bunched condition on the horizontally extended lugs 12 are free to drop onto the receding pressure ring 13.
