Definitions

  • a wire-rolling mill may be provided, after the last rolling stage, with a coil-forming apparatus adapted to spin the wire into individual turns, overlapping the previous turns, on a continuous conveyor or other transport surface, eg an endless belt.
  • Another object of this invention is to provide a system whereby selected lengths of coiled wire can be separated from the remainder of a train of coils which can operate substantially independent of the rolling speed, introduces no delay in the rolling operation and is more effective yet simpler and less expensive than earlier apparatus for a similar purpose.
  • the collected coils, forming a bundle can be separated from the prior coils or the succeeding coils or bundles formed therefrom. It may be desirable to remove the bundle of coils laterally whereby the measuring and severing apparatus serves to separate sets of overlapping wire coils from one another.
  • the invention comprises a conveyor or continuously moving transport surface, operating at a rate determined by the rolling speed of the wire-rolling mill and the rate at which a wire-coiling apparatus (see application Ser. No. 196,962) deposits succeeding turns in overlapping relationships upon the transport surface.
  • the collecting station is provided, in accordance with the present principles, with a framework or support straddling the conveyor from above and a collecting plate, as described, which can be tilted downwardly toward the conveyor surface to intercept a leading edge of an overlapping coil of wire and can be tilted upwardly to clear the coils on the conveyor,
  • means is provided for tilting the plate downwardly, i.e.
  • the coil-engaging edge of the plate is provided with a gate which blocks passage of the wire connecting a coil on the conveyor surface and a coil on the plate into a slot formed in the plate and converging in the direction of movement of the conveyor surface until the gate is swung away by a fluid-responsive means connected to the plate.
  • the gate which may be a pickup bar or plate of a wedge-shaped profile with a direction of convergence toward the oncoming coils, may be pivoted along a lateral edge of the plate.
  • One of the forwardly convergning edges of the slot, into which the connecting wire strand is guided, is preferably provided as a fixed cutting edge which cooperates with a swingable cutting edge below the plate and operated by a second fluid-responsive means.
  • the collecting plate is displaceable relative to a stripper, having a pair of rolls flanking the coils and adapted to rest against the plate so that a bar thereon can hold back the collected coils or bundle as the plate is retracted.
  • FIG. 1 is a side-elevational view, partly in diagrammatic form, of an apparatus for collecting, gathering or accumulating rolled-wire coils according to the present invention and severing the collected coils from a continuous supply thereof;
  • FIG. 2 is a plan view of the apparatus of FIG. 1 with the conveyor means for the continuous supply of coils being omitted;
  • FIG. 3 is a detail view, in plan, and in diagrammtic form, of the collecting plate according to the present invention.
  • FIG. 4 is a section taken along the line IV IV of FIG. 3;
  • FIG. 5 is a view similar to FIG. 1 showing the cooperation of the stripper means and the collecting plate.
  • FIGS. 1 and 2 show an apparatus for collecting a selected number of coils 6 deposited in overlapping relationship upon a conveyer which is represented diagrammatically at 5. It should be noted that the rolling mill in which the wire is produced substantially continuously, the coil-forming apparatus in which the wire turns are shaped to lie in overlapping relationship, and the conveyer means for the continuous supply of these overlapping coils are conventional as previously described.
  • the apparatus comprises a frame construction or gantry l, which straddles the conveyor 5 and comprises a pair of posts la on the right-hand side of the conveyer and a pair of posts lb on the left-hand side thereof.
  • a crosspiece 4a extends across the conveyer and, parallel thereto, the framework 1 comprises a pair of rails 3 parallel to cross-piece 4a.
  • the transport direction is represented by the arrows A and proceeds from left to right, the conveyer operation being continuous and uninterrupted by the operation of the present apparatus.
  • a collecting plate 2 whose basic configuration can be seen in FIGS. 2 and 3, is secured to a pair of depending arms 2a and 2b on each side of the conveyer, the arms being journaled to respective rollers or wheels 7 and 8.
  • the sections 9, 9 and 9 thus constitute cams which are followed by the rollers 8.
  • the plate and its arm 2b are tilted in the counterclockwise sense about the fulcrum defined by the axis of wheel 7 to lower the leading edge 20 of the plate 2 as the entire plate assembly is shifted in the direction of arrow B by a hydraulic or pneumatic cylinder 10. In this manner the tilt of the plate 2 can be altered substantially instantaneously.
  • the cylinder 10 is anchored, as shown in FIGS. 1 and 2, to a further framework 4b, and has a piston 10a connected by a hinge joint 10' to the plate 2.
  • the maximum extension of the piston 10a is shown in FIG. 5.
  • the leading edge of the plate 2 is also provided, as may best be seen in FIGS. 1 and 2, with a guide plate 11 which also forms a gate overlying the plate 2 and hinged at the lefthand side thereof by a pivot 13 to this plate.
  • the gate 11 is a bar having a wedge-shaped profile which converges in the rearward direction (arrow B), i.e. in the direction turned toward the oncoming coil 6.
  • a lever 130 connected to the arm 11 via the pin 13, is articulated at 13b to the piston 12a of a cylinder 12 which, in turn, is hinged at 12b to a lateral projection 2d of the plate.
  • the bar 11 Upon extension of the piston 12a, the bar 11 is swung into the dot-dash position shown at FIG. 2 to expose a wedge-shaped cutout, notch or slot in the leading edge of the plate 2 (see FIGS. 2 and 3).
  • the wedge-shaped cutout of the plate is defined between a pair of forwardly converging edges 14 and 15 and is so dimensioned that the base of the cutout has a length V equal at least to one half the width W of the plate and the cutout has a length L which can approach one half the length D of the plate.
  • the length L of this plate corresponds to one half W.
  • a swingable blade 16 which eo-operates with a hardened and reinforced cutting edge 15' formed along the edge 15 to sever a wire upon operation of a hydraulic or pneumatic cylinder 17.
  • the latter is articulated at 17a to the underside of plate 2 and has a piston 17b which is pivoted at 16a to the bell-crank lever 16.
  • the latter has a pivot 16b supporting it on the underside of the plate and is formed with the cutting edge 16c co-operating with fixed blade 15'.
  • the apparatus comprises a pair of fixed guides 18 within which a bar 19, extending across the conveyer, is springbiased in the downward direction while a pair of rollers 20 support the bar slightly above the plate 2 when the latter is advanced.
  • the assembly 18 20 constitutes a stripper arrangement which is adapted to retain the collected coils upon withdrawal of the plate, as will be apparent hereinafter.
  • the plate 2 With the apparatus in the starting position illustrated in FIGS. 1 and 2, and under the control of some programming means, means responsive to coil weight, or the signal of an operator, the plate 2 is shifted to the left by cylinder to cause the wheels 8 to ride upon ramp 9' and cause the leading edge 20 to tilt downwardly and engage the oncoming coil 6 and ride up upon the gate 4 and the plate 2 (FIGS. 3 and 4).
  • the coils which are gathered on the plate 2 are closed upon one another because of the resistance to forward movement imposed by the plate and hence the number of turns collected is greater than that which would correspond to a similar length of the conveyer 5 and a spacing is produced between sections of coil thereon.
  • the gate 11 is swung back to expose the cutout defined between the edges 14 and 15.
  • the wire strand 6" between coil 6 upon the plate and coil 6 on the conveyer (FIG. 4) is drawn into the cutout and is severed when the rearmost portion 6" of the first coil reaches the region of the blade arrangement l6, 15'.
  • the stripper bar 19 rides up upon the plate 2 and engages the leading edges of the coils thereon.
  • the coils are dislodged and deposited upon the plate or are allowed to be withdrawn laterally. There is, of course, no interruption of the conveyer operation. Because of the storage capacity of the plate 2, the operation of the system is independent of the rolling speed.
  • An apparatus for collecting wire coils from a conveyer carrying a succession of such coils in overlapping relationship in a transport direction comprising:
  • said support means comprises a pair of rails extending parallel to said conveyer and said direction, said rails being formed with camming surfaces of different heights, said plate being formed with cam follower rollers engaging said camming surfaces for selective tilting of said plate.
  • said cutting means includes a cutting edge formed on said plate adjacent said apex, and a further cutting edge swingably mounted on the underside of said plate and cooperating with the cutting edge formed thereon.
  • said stripper means comprises a bar adapted to extend across said plate and a pair of rollers at opposite ends of said bar, spaced apart approximately by the width of said plate and engageable therewith.
