Definitions

  • ABSTRACT Wire coming hot from a rolling mill is carried to a coil stacker on an apertured conveyor on which it cools after being deposited thereon in a series of overlapping loops by a dispenser including a continuously rotating tubular arm which is centered on a horizontal axis.
  • a cutter ahead of the dispenser responsive to a delayed trigger pulse from a photocell which monitors the entry of the leading end of the wire into an observation zone, removes the irregularly formed leading portion of any fresh length of wire but isinhibited from operating at instants when the arm is so oriented that the tip of the trimmed wire would reach its exit end in a position in which the wire tip could become entangled in the mesh with a grid-type conveyor or fall between parallel conveyor bands.
  • This inhibition is brought about by a signal generator, such as an induct'ance' co-operating with a magnet carried by the rotating arm, whose output either enables the cutter drive in a predetermined arm position or blocks it during the passage of the arm over certain parts of its orbit.
  • a signal generator such as an induct'ance' co-operating with a magnet carried by the rotating arm, whose output either enables the cutter drive in a predetermined arm position or blocks it during the passage of the arm over certain parts of its orbit.
  • Our present invention relates to an apparatus for the cooling of hot wire, especially rolled steel wire, preparatorily to winding same into a coil.
  • Rotation of the wire about a horizontal axis not only simplifies the advancing of the wire to the dispenser but also results in amore uniform loop pattern as compared with dispensers centered on a vertical axis, since in the latter case the speed of the dispenser outlet relative to the conveyor varies considerably throughout a cycle of rotation.
  • a cutter may be positioned ahead of the dispenser and may be actuated by a delayed trigger pulse from a preferably photoelectric detector upstream of the cutter monitoring the arrival of the tip of the wire at an observation point.
  • the delay undergone by this trigger pulse is so chosen that, with the wire fed at a predetermined velocity, thecutter is actuated as soon as a leading portion of desired length has moved past the cutting station.
  • the length of this portion, which is to be discarded, may be on the order of meters.
  • the cutter operates instantaneously and reopens rapidly to let the tip of the trimmed body of wire advance to the dispenser where it enters the guide tube whose eccentric outlet may be positioned at that instant anywhere along its orbit.
  • the general object of our present invention to provide an improved wire-coil winder of the character just described in which the emergence of a wire tip from the continuously rotating dispenser is timed to coincide invariably with a relatively favorable dispenser position, regardless of the orientation of the dispenser at the moment of operation of the monitoring detector.
  • the signal generator at the dispenser may be of any conventional type, e.g., mechanical, photoelectric or electromagnetic, with a movable element (such as a magnet) carried on the rotating dispenser and with a co-operating fixed element (such as a pick-up coil) positioned for periodic excitation thereby.
  • the output signal of this generator may be either an enabling pulse or a blocking pulse recurring at least once per cycle of rotation; in the first instance the delayed trigger pulse should be broadened to a width at least equaling the recurrence period, whereas in the second instance this width need only exceed that of the blocking pulse.
  • FIG. 1 is a somewhat diagrammatic overall view, partly in section, of a wire-coil guide embodying the invention
  • FIG. 2 is a fragmentary view similar to FIG. 1, showing a partial modification
  • FIGS. 3 and 4 are two time diagrams relating to the operation of the systems of FIGS. 1 and 2, respectively.
  • FIG. 1 we have shown a feeder, including two counterrotating grooved rolls 21 and 22, for a wire 1 coming hot from a rolling mill not illustrated.
  • a monitoring station 23 includes a slotted wire guide 24 defining an observation zone, a lamp 25 on one side of that guide and a photocell 11 on the opposite side; this photocell is thus illuminated in the absence of wire 1 and cut off when the leading end of that wire traverses the guide 24.
  • a differentiation circuit 26 (also including the necessary source of energy for the photocell) derives from the resulting conductivity change a sharp trigger pulse P (FIG. 3 or 4) which then passes through a delay circuit 12 where it undergoes a predetermined but preferably adjustable retardation 8 on its way to a pulse separator 27.
  • the latter circuit which could also precede the delay network 12, converts a delayed replica P of the spike P into a broad pulse P" of duration T which is fed to an AND gate 28 controlling the operation of a driving mechanism 10 for the movable blade 9 of a cutter also including a fixed counterblade 9.
  • a dispenser 3, separated from the cutter 9, 9 by a distance sufficient to allow for the severance of the desired length of leading wire portion, comprises a bent tube 5 whose exit end has an outlet 5' offset from the horizontal axis of its inlet portion, the latter being journaled in bearings 29 for continuous rotation about-this axis by means of a motor 30 and a belt, chain or other transmission 31.
  • a funnel 4 enshrouds the outlet end 5' of the tube 5 carrying a bar magnet 14 which periodically excites an electromagnetic pick-up coil 13 mounted on the funnel near the orbit of the magnet. This excitation generates a timing pulse Q (FIG.
  • the wire I exiting from tube 5 is deposited in successive loops 16 on the surface of an endless conveyor 7 here shown as consisting of wire netting or thelike. These loops are unloaded, at the discharge end of the conveyor onto a stacker-8 which assembles them into a coil.
  • FIG. 2 we have shown the tube 5 provided with a modified signal generator represented by a cam 14a and a set of normally open 'contacts 13a periodically closed by that cam, contacts I3a being inserted between a voltage source 32 and an inverting input of an AND gate 28a whose noninverting other input receives the output of pulse shaper 27 as in the embodiment ofFIG. 1.
  • Cam 14a may be of quadrantal shape so as to close the contacts 13a during a quarter of a revolution, thereby generating a blocking pulse Q (FIG. 4) which inhibits the operation of cutter drive while the tube 5 is in an unfavorable position.
  • the duration T of the broadened trigger puls e P" need only exceed the width of blocking pulse Q in order to actuate the cutter at the trailing'edge of the blocking pulse if the two pulses partly coincide, as shown.
  • FIG. 2 further shows, by way of example, a modified conveyor 7a consisting of a plurality of transversely spaced, endless bands.
  • the conveyor as well as the signal generator of FIGS. 1 and 2 are, of course, interchangeable 0r replaceable by equivalent conventional devices. Monitoring detectorll could also be replaced by equivalent means such as, for example, a mechanical feeler.
  • the loops 16 may have a diameter of, say, 100 to 120 cm, which in the system of FIGS. 1 and 3 may result in a variation of the length of the severed leading portion by up to about 3.8 m.
  • This variation may be halved by the provision of a pair of diametrically opposite coils 13 on the funnel 4, connected in parallel, the locations of these coils being so chosen as to let the wire emerge in the most favorable positions of the tube 5.
  • the variation in length will be reduced to a quarter of its aforestated magnitude even if the signal generator produces two pulses Q per cycle, e.g.
  • monitoring means disposed ahead of said dispenser for generating a trigger pulse upon detecting the arrival of the leading end of a fresh length of wire fed at a predetermined rate to said dispenser;
  • control means for said cutter means responsive to said trigger pulse said monitoring means being provided with a timing circuit including delay means for retarding the arrival of said trigger pulse at said control means by a predetermined period corresponding to the length of the leading portion to be severed;
  • said dispenser comprises a bent guide tube with an entrance end centered on a substantially horizontal axis of rotation and an exit end generally transverse to said axis.
  • timing circuit includes pulse-shaping means for broadening the delayed trigger pulse to at least a substantial fraction of a cycle of rotation of said dispenser.
