Definitions

  • ABSTRACT Improved conveyor roll structure for retaining thereon advancing elongated work pieces such as steel rods, bars, or the like wherein the roll exhibits a first retaining surface of revolution inclined at an angle less than 45 to the axis of the roll and a second inclined retaining surface of revolution meeting the first at an angle greater than 90 and inclined from the roll axis at an angle of lea than 45', the second surface of revolution having a depresion therein whereby the cross section of said second surface presents a generally concave aspect and the second surface extends outwardly from the juncture of the first and second surfaces a predetermined distance such that the longitudinal centroid of the conveyed work piece may be contained within the vertical extent of the first and second retaining surfaces while being advanced across a plurality of rolls comprising the conveyor.
  • This invention relates generally to rolls utilized in conveyor lines and particularly to rolls installed in the line where their centerlines are skewed from the perpendicular of the conveyor line.
  • a line may be installed through an annealing furnace in which rods and bars of round, square, and rectangular shapes are heat treated.
  • annealed bars of round, square, and hexagonal cross sections varying from five-eighths of an inch to 4 inches in diameter and from oneeighth of an inch to 4 inches thick and up to 4 inches wide for rectangular cross sections may be treated in such a furnace by being heated to approximately 2,200 F. while being conveyed through the furnace.
  • the workpieces are conventionally fast quenched as they exit the annealing furnace.
  • Said second surface of revolution has a depression therein whereby the cross section thereof presents a generally concave aspect, the second surface of revolution being adapted to extend outwardly from the juncture of the first and second retaining surfaces a predetermined distance whereby the longitudinal centroid of the workpieces may be contained within the extent of the first and second retaining surfaces while being advanced across a plurality of rolls comprising the conveyor.
  • FIG. I is a side elevation of an improved conveyor roll of my invention, appearing in section.
  • FIG. 2 is a partial view of the invention illustrated in FIG. 1.
  • FIG. 3 is a front elevational view of an alternative embodiment of my invention.
  • FIG. 3a is a side elevational view of the embodiment of FIG. 3.
  • FIG. 4 is a schematic illustration of a conveyor using the rolls of the invention, showing the manner in which they are skewed.
  • reference numeral 2 indicates a roll body adapted at either end to be conventionally mounted in a conveyor line (not shown).
  • a plurality of rolls would be mounted over the full extent of the conveyor.
  • the preferred embodiment of the roll described herein is included in a conveyor line extending through an annealing furnace.
  • Rolls 2 are mounted on center lines approximately 2 feet apart and throughout the distance of the furnace as well as in the areas of entrance and exit thereto.
  • Roll 2 may be adapted with motor means (not shown) to advance a workpiece progressively along the conveyor line.
  • the improved roll structure of my invention illustrated in the figures includes a first retaining surface 6 being a surface of revolution inclined at an angle A less than 45 to roll axis 8.
  • the retaining surface 6 is contained on a sleeve 10 which closely fits over roll body 2 and is secured thereto by conventional means such as keys 12.
  • second retaining surface 14 Further contained on roll body 2 is second retaining surface 14, also a surface of revolution and centered about roll axis 8.
  • Second retaining surface 14 may also be contained on sleeve 16 as illustrated in the described embodiment, and secured conventionally to roll body 2.
  • retaining surface 14 exhibits a varying slope to roll axis 8.
  • the surface 14 is broken into two surfaces 17 and I8.
  • the initial slope of surface [4 lies in surface I7 forming an initial slope at angle B.
  • Surface 14 exhibits a second slope at angle C and lies in surface 18.
  • the slope of surface [8 measured by angle C is greater than the slope of surface I7 measured at angle B, however, both are inclined to roll axis 8 at angles of less than 45.
  • surface 14 is a surface of revolution of a compound line extending from the juncture 20, of surfaces 6 and I4 to point 22, a predetermined distance from juncture 20 and further to point 24, a predetermined distance fromjuncture 20.
  • angle A is approximately 38, angle B, approximately 40, and angle C, approximately 43.
  • Surface 6 extends a length of 2% inches from juncture 20.
  • Surface 17, reaching from juncture 20 to point 22 extends a distance of 2% inches and surface 18, reaches from point 22 to point 24 extending a distance of 2% inches.
  • the surfaces 6, I7, and 18 are adapted for rods generally five-eighths inches in diameter up to 4 inches in diameter and bars rectangular in cross section from oneeighth inch in thickness up to 4 inches in thickness and up to 4 inches in width.
  • an additional retaining surface 26 may be included being a surface of revolution from an are extending from point 24 to a vertical to roll axis 8.
  • each V groove consists basically of two surfaces (6 and 14) inclined with respect to each other and the axis of the roll 8 upon which they are carried.
  • the V shape is adapted for rolls which are mounted in a manner skewed from a line extending perpendicular to the furnace longitudinal center line or pass line of the conveyed material up to approximately 8". (See FIG.
  • the roll body 2 is skewed to cause the workpiece W to ride in the V and the retaining surfaces 6 and 14 preferably against side 14 tending to ride up the advance surface 14, which in the invention is so adapted with the increasing slope to contain the work piece W within the V area.
  • surface 14in cross section is composed of two retaining surfaces of revolution, the first (6) being inclined at an angle of approximately 38 to roll axis 8 and the second (l4) generally being inclined at an angle of greater than its initial slope as at surface 17.
  • the total length of surface 14 is sufficiently long to contain the maximum expected deviation from longitudinal straightness of the bar to be processed.
  • the end of the inclined surface 18 terminates in a third retaining surface 26 being an upward concave curve to further deepen the slope of the overall surface 14 to increase the maximum amount of deviation from straightness of workpiece W which may be conveyed by the roll 2.
  • the overall surface 14 in cross section appears as two flat lines 17 and 18 of different slope and a third surface 26 being a concave curve attached thereto, the cross section of surface 14 may exist as a long radius curve or a compound curve meeting the foregoing slope requirements.
  • the sleeve may be made elliptical in shape as at 16'. This may also be advantageous in situations wherein weight restrictions on the roll body 2 are important. It may be further appreciated that the multiple ellipsoid sleeves may be oriented on different axes to provide a balancing of the weight about roll body 2 having a plurality of such retaining surfaces.
  • a conveyor for conveying an elongated workpiece such as steel rods, bars, or the like through a chamber such as a furnace for heat treating said workpieces, each of said rolls having retaining means for guiding said workpiece through said chamber and corn risin a first retainmg surface of revolution inclined at an angle of ess than 45 to the axis of said roll; a second retaining surface of revolution meeting said first surface at an angle of greater than and inclined at an angle of less than 45 to the roll axis, said second surface of revolution having a depression therein, the cross section thereof presenting a generally concave aspect, said second surface of revolution being adapted to extend outwardly from the juncture of the first and second surfaces a predetermined distance so that the longitudinal centroid of said workpiece is contained within the extent of said first and second retaining surfaces while being advanced along said conveyor; the rolls being mounted for rotation about axes which are all skewed in the same direction with respect to the longitudinal center line of a work
