Definitions

  • This invention relates to improvements in a rolling mill for processing cold metal strip and more particularly to the provision of means for fully automatically advancing a reel of coiled strip down a ramp to a position exterior of spaced rolling mill stands at which time it is elevated out of contact with the ramp, and the depending tail portion of the strip is fed by an improved means into the bight between the work-engaging rollers.
  • the then depleted reel is disengaged from the unwinding machine, lowered onto the ramp and moved forwardly into a position of rest between the rolling mill stands where it is retained until the strip from a successive coil of strip is wound upon the new reel, whereupon it is moved from its position of rest downwardly through an arcuate path into an assembled position with the winding machine preparatory to receiving a new supply of coiled strip material thereon.
  • strip reels or spools have had dimensions where the diameter and width has been of one meter or less.
  • such an accomplishment becomes physically impossible with reels who dimensions considerably exceed one meter.
  • one of the objects of the invention is to provide an elevated inclined ramp which extends between the spaced stands of the rolling mill, above the rolls, and includes power operated means for elevating the reel of coiled strip thereabove preparatory to feeding the tail end thereof into the bight of the work-engaging rolls.
  • Another object of the invention is to provide horizontally spacedly arranged tens-ioning rollers through one of which tension may be applied to the advancing strip as desired.
  • Still another object of the invention is to provide a pivotally mounted power-driven means which includes an endless belt that, when swung into a cooperative position relative to the tension rollers and the rolling mill stand, facilitates entry of the coiled strip into the bight of the work-engaging rolls.
  • a further object of the invention is utilizing the perpendicularly movable strip tensioning roller also for the purpose of tensioning the conveyor belt assemblage.
  • Another further object of the invention is to provide a grappling means which is adapted to remove a reel that is depleted of its strip subsequent to advancement beyond its position of rest and place it in a position whereupon a new supply of metal strip will be formed thereon.
  • FIG. 1 is a side elevational view partially in section graphically depicting a full coil of strip material with its free end being fed to the work-engaging rollers, as well as a depleted roll awaiting transfer to a work-receiving position;
  • FIG. 2 is a side elevational view partially in section showing the power-driven endless belt means in a retracted inoperative position.
  • FIG. 1 of the drawings there is shown in elevation at 10, a typical rolling mill stand (only one side shown), within the window 11 of which is depicted in cross section the fourhigh mill stand comprising work-engaging rollers 12 and 13 and back-up rollers 14 and 15, respectively.
  • an inclined ramp 16 Positioned above the upper roller 14 and extending substantially the width and length of the spaced rolling mill stands is an inclined ramp 16 which includes horizontally spaced trackways (one visible) on which is provided at any suitable location, preferably within the confines between the space stands 10, an abutment or stop means 17 for a purpose that will be better understood as the description progresses.
  • a roll of coiled strip material 18 which is to be processed by the work-engaging rollers is positioned on the trackway constituting the inclined ramp 16 with the opposite extremities of the reel or spool means 19 supported thereon and the coil suspended therebetween, as is shown in broken outline.
  • a pair of elevating means 20 are approximately secured for rotation to the outboard side walls of each of the trackways 16 and include at the forward end an upturned stop 21 and at the rear extremity thereof a coupling means 22 which is associated with a power means 23 and thereby adapted to raise the coil 18 by means of the reel extremities from the trackway into an unwinding machine generally indicated at 24.
  • the unwinding machine which forms no part of the invention thereof, comprises, as usual, suitable conical members, at least one of which is driven (not shown) which are brought into engagement with the reel and rotated at any appropriate speed commensurate with the driving speed of the work-engaging rollers.
  • winding machines are also positioned on the opposite side of the rolling mill stand and include power-driven means adapted to be associated with a reel 25 and driven at a speed compatible with the rate with which the strip exits from the bight of the rolling mill.
  • a group of three tensioning rollers 26, 27 and 28 are suitably supported in any acceptable manner between the spaced stands of the rolling mill with the intermediate roller 27 being arranged for movement in a limited vertical path of travel between a lowered position, such as that shown in FIG. 1 where this roller is not then in engagement with the strip, to an uppermost position (FIG. 2) where it engages and tensions the strip after the tail end thereof has been fed through the mill and secured to the winding reel.
  • V-shaped plates 30 Pivotally secured, as at 29, between the rolling mill stands are a pair of V-shaped plates 30 (one shown) which are maintained in parallel spaced relation by means of rollers 31 and 32, either one of which may be powerdriven and thus adapted to drive an endless belt 33 and comprises a conveyor assembly 34 adapted to feed the strip to the Work-engaging rolls.
  • the conveyor 34 now occupies the position necessary to feeding the tail end of the strip material to the work-engaging rolls. It will be observed that the inclined upper flight of the conveyor belt is spaced slightly from the tensioning rollers 26 and 28, whereas roller 27 is in its lower retracted position and now inoperative.
  • a further improvement of this invention involves means for facilitating handling of spent spools or reels depleted of the coil strip by advancing them from the unwinding machine 24 to a stop means 17 subsequent to their being lowered upon the trackway 16.
  • This arrangement is particularly advantageous since the strip when it leaves the rolling mill must be again wound on another reel.
  • empty reels even alone are very unmanageable to handle with simple hoisting gear as they are very heavy and unwieldly.
  • the depleted reel is permitted to roll to a predetermined point on the trackway above the four-high rollers and there detained by stop 17 preparatory for advancement to the winding station, to the left of FIG. 1, when a new reel is desired.
  • a lever 41 Rotat-ably mounted for movement in an arcuate path of travel approximating 180, on a bracket 40, at any suitable location between spaced stands, is a lever 41 which includes at its free end power operated grappling arms 42 and 43.
  • a rolling mill including Work rolls comprising strip supply means disposed at one side of the rolling mill at an upper portion of the frame thereof and a winding means for the strip adjacent to the roll portion of the rolling mill at the other side of the frame, a substantially horizontal ramp affixed to said frame at the upper portion of said frame and arranged to support said strip supply means, and unwinding means for the strip mounted adjacent to the ramp, means to deposit a coil reel of said strip on said ramp, means to place said reel of strip in said unwinding means in such a manner that the trailing end thereof depends below the ramp, and a conveyor including feed means positioned adjacent to the point of introduction of the strip between the work rolls of the rolling mill, whereby the trailing end of the strip from the reel by slow unwinding thereof may thus be manually advanced onto the feed means and thence between the work rolls of the rolling mill.
  • means comprising a pivoting pincer arranged to grasp and lower the empty mandrel into the winding position of the strip emerging from the rolling mill.
