Definitions

  • the chamber (often referred to in the industry as a reforming chamber or tub) includes novel mechanism in the form of fingers which may be moved simultaneously into the upper part of the chamber to intercept the leading rod convolutions coming from the next billet for a sufficient time to permit the previously formed coil to be pushed laterally out of the lower part of the chamber. As soon as the previous coil has been removed, the fingers are retracted to allow the temporarily arrested rings to fall to the floor of the chamber to be followed by the remaining convolutions of the rod as they are continuously delivered by the conveyor or laying head to the chamber. Alternatively, the fingers may be actuated to intereept the falling convolutions at any intermediate position to provide an opportunity to cut the rod, thereby to subdivide the rod into two or more coils.
  • the rings On leaving the conveyor, the rings are delivered in rapid succession to the open upper end of a collecting chamber in whichthe rod rings falling gravitationally are assembled into a suitable coil.
  • the rings may be delivered directly to the coilforming chamber from a laying head directly thereabove.
  • the leading rings of the next billet must be intercepted to give time for removal from the chamber of the previously formed coil.
  • the size and weight of the coil depends upon the size of the billet from which the rod was rolled. Since the last ring of one coil is only a short distance ahead of'the first ring of the next on the conveyor or coming from the laying head, it is necessary to provide some means for temporarily stopping or preventing the descent of the first rings of the next coil until the previously formed coil at the bottom of the collecting chamber can be removed therefrom.
  • This invention is, therefore, particularly concerned with a novel mechanism in the form of a plurality of specially shaped fingers which may be simultaneously moved inwardly from the circular wall of the coil-forming chamber a sufficient distance to intercept the leading rings of the next coil as they are delivered to the chamber from the conveyor or the laying head. These fingers remain in inward position until the previously formed coil has been removed from the lower part of the chamber after which the fingers are retracted outwardly of the chamber wall permitting the intercepted rings to fall to the bottom of the chamber. All following rings delivered by the conveyor or laying head then build up on the bottom rings until the next coil has been completed.
  • a control mechanism at the top of the chamber causes the fingers to be actuated to move to inward position where they will be ready to intercept the first rings of the next billet to provide time for removal of the coil just previously assembled at the bottom of the chamber.
  • the fingers may also be actuated to intercept descending rod rings at some selected intermediate time in the delivery of rings to the chamber.
  • the rod may then be severed at the intercepting finger position to produce a coil therebelow of a fractional weight of the billet. For example, if a 3,000 lb. billet were being rolled, the fingers could be moved inwardly when 1,500 lbs. of rod had been delivered to the chamber. The rod could then be cut at the intercepted position to produce a 1,500 lb. first coil and thereafter upon removal of the first coil and withdrawal of the fingers, a second coil of 1,500 lbs. would be produced.
  • FIG. I shows in side elevation part of a conveyor delivering rod rings to a reforming chamber.
  • the coil-forming chamber and the finger mechanism are shown in vertical section along with discharging mechanism at the lower portion.
  • FIG. 2 is an enlarged side elevation of the upper portion of the reforming chamber showing the finger-actuating mechanisms in more detail. The chamber is broken away in part.
  • FIG. 3 is an enlarged plan view of FIG. 1 with the rod rings and details of the conveyor omitted for clarity.
  • FIG. 4 is an enlarged vertical section taken on the line 4-4 of FIG. 3.
  • FIG. 5 is an enlarged vertical section taken on the line 5-5 of FIG. 3.
  • FIG. 1 there is shown a conveyor 2 carrying thereon a succession of continuous nonconcentric rod 0 rings 4. As these rings, or convolutions, approach the end of the conveyor, they may be assisted in maintaining a generally horizontal dropoff position through the use of overlying feed chain 6.
  • the rings on leaving conveyor 2 drop into the top end of a coil-forming chamber 8.
  • the initial descent of the rings is illustrated at 4a.
  • These first rings are shown as being intercepted by a plurality of fingers 10 which extend inwardly through openings 14 in the upper wall 12.
  • the rings of the preceding billet have been collected at the bottom of chamber 8 to form a complete coil 16.
  • This coil rests on a-bottom support 18.
  • a mandrel 20 with its upper tapered end well above fingers 10 assists in locating properly the descending rod rings.
  • the mandrel 20 is moved downwardly by means not shown, far enough to clear the bottom of coil 16.
  • a pusher 22 is then actuated to force coil 16 to a conveyor or delay station position indicated at 160.
  • the rings may be dropped directly therein in known manner by a conventional laying head (not shown) positioned over the coil-forming chamber.
  • a laying head and coil-forming chamber is shown gan US. Pat. No. 3,204,940.
  • the chamber has been generally indicated at 8 and the upper part of the chamber at 12.
  • This part 12 at its top carries supports 26 on which is mounted a crosswise extending rod 28 from which depends a flag 30.
  • This flag is engaged by the rod rings leaving the conveyor to assume the dotted line position shown in FIGS. I and 2.
  • the partial rotation of rod 28 by movement of flag 30 causes actuation of a switch which in turn through suitable mechanisms to be described causes appropriate movement of the fingers'IO.
  • a rotary oil hydraulic actuator 32 is fixedly mounted on the upper end of a shaft 34.
  • the shaft is supported in a lower bearing 36 and an upper bearing 38.
  • Bearing 36 is carried by a circumferentially extending supporting plate 37.
  • Actuation of the hydraulic actuator 32 causes shaft 34 to rotate clockwise or counterclockwise in accord with the position of any suitably located ring-sensing device such as, for example, flag 30.
  • a spur gear 40 is mounted on shaft 34 and keyed thereto by key 42.
  • Gear 40 has in the patent to Moran upper cylindrical collar 44 on which is clamped as at 46 the outer extension of one of the fingers l0. As can be seen in FIGS. 3 and 4, this finger 10 extends through its opening 14 in upper wall 12 of chamber 8.
  • all of the eight fingers 10 are identical in configuration.
  • the number of fingers could be more or less according to size of the chamber and rod rings.
  • the part of each finger that moves in and out of the chamber is a circular segment having its center at the axis of the shaft on which it turns.
  • the fingers 10 are moved in and out in unison and this is accomplished in the following manner.
  • the actuator 32 as previously explained, is mounted on shaft 34.
  • This shaft also carries its finger 10 which is mounted on the sleeve 44 of gear 40.
  • the other seven fingers are mounted on different type shafts 52 which are illustrated in FIGS. 3 and 5.
  • Each of the shafts 52 is nonrotatably mounted in lower and upper supports 37 and 49.
  • a keeper 51 attached to support 49 holds shaft 52 against vertical and rotary movement.
  • Each gear 55 has an upwardly extending collar 56 on which is clamped as at 58 the outer end of its finger 10.
  • the one shaft 34 and the other shafts 52 have their axes vertical and parallel and located in circular path.
  • the gear 40 and gears 55 are all the same size.
  • Surrounding and engaging all gears is an internal ring gear 60.
  • This ring gear is mounted for easy rotation in a circular bearing 62 with antifriction elements 64 and 65 therebetween.
  • Bearing 62 is bolted as shown in FIGS. 4 and to the circumferentially extending supporting plate 37 mounted about the periphery of wall 12.
  • a protective and dirt-excluding cover 68 is mounted on the top of ring gear 60 with its outer portion overhanging the bearing elements 62 and 64.
  • the rotation of the one shaft 34 is transmitted to all of the other gears 55 by means of the surrounding ring gear 60.
  • the spur gears could be replaced by sprockets of the type used on bicycles, and the sprockets could be connected for simultaneous rotation by a suitable chain extending about their exteriors.
  • Another alternative would be to substitute small drums for the spur gears and connect the same by a continuous cable which would have two or three turns around drum. This latter construction is not, however, considered as satisfactory as a gearing arrangement because of the possibility of slippage.
  • two or more actuators could be mounted on other shafts in a manner similar to that shown in FIG. 4. All of the actuators would be electrically controlled to function simultaneously.
  • Each finger 10 may have a replaceable wear insert 78 included in its upper surface as the friction between fingers l0 and the rod rings when the fingers are being withdrawn is considerable.
  • the leading ends of the fingers be sharpened in a horizontal direction to minimize the possibility of a finger engaging the side of a ring and forcing it inwardly to create an out of round condition.
  • a chamber adapted to receive a falling succession of continuous rod rings delivered thereto by a conveyor or laying head, said chamber having means intermediate its vertical dimension for arresting temporarily the descent of said rings within said chamber, said arresting means comprising a plurality of curved fingers movable in a circular path in a horizontal plane into said chamber through apertures in the chamber wall to arrest rings falling thereon and movable out of said chamber to the extent necessary to release said previously arrested rings, said fingers having extensions thereof outside said chamber wall mounted on parallel pivots to pennit said circular movement of said fingers thereabout, that portion of each finger entering said chamber being curved in the form of a segment of a circle having its center at its said pivot, means for simultaneously causing movement of said fingers inwardly and outwardly of said chamber comprising a gear attached to each extension and rotatable about its pivot, all said gears being engaged by a surrounding rotatably movable element whereby movement of any of said gears or element will cause corresponding rotation of all other gears and identical movement of the related fingers.
  • said means for rotating said one gear comprising a rotary oil hydraulic actuator.
  • said chamber having mounted therein a vertically movable mandrel for guiding the said descending rings to form a proper rod coil, the upper end of said mandrel when in uppermost position being above the plane of said fingers for insuring positioning of said rod rings on said fingers when said fingers are in inward position within said chamber.
