Definitions

  • MATERIAL HANDLING APPARATUS [75] Inventors: William J. Hill, Holden; Kenneth L.
  • ABSTRACT A material handling apparatus which includes a pusher mechanism operating in conjunction with fixed and movable stops to individually separate elongated elements from a batch and to laterally feed each separated element into a given path.
  • This invention relates generally to the art of material handling, and is particularly concerned with an improved apparatus for selecting individual elongated elements from a batch and for laterally feeding each element thus selected into a given. path.
  • the invention overcomes the problem of selecting one elongated element from a batch of elements arranged in a generally parallel side by side formation.
  • the elements are placed on a roller table, which is the preferred embodiment to be hereinafter described in greater detail, includes skewed driven rollers arranged to impart both axial and transverse motion to the elements. The axial motion is eventually limited by a first stop having a flat surface against which the front ends of the elements are aligned.
  • the elements continue to move laterally across the first stop until the front end of the leading element moves past the end of the first stop.
  • the leading element then continues axially past the first stop into engagement with a third stop.
  • continued lateral movement of the leading element is arrested by a second disappearing stop which in its raised operative position is located between the first stop and the path into which each element is to be individually fed.
  • the first stop is laterally adjustable with reference to the second stop so as to provide a gap therebetween which is wide enough for one element.
  • the second stop is retracted and a pusher contacts the end of the leading element and pushes it laterally into the path.
  • the pusher is then retracted and the second stop returned to its raised position as the next succeeding element advances to the ready position.
  • the invention is particularly useful in the handling of product lengths produced by a rolling mill, although it will be appreciated from the following description that other uses are also contemplated.
  • FIG. I is a plan view of an apparatus embodying the concepts of the present invention.
  • FIG. 2 is a sectional view taken along lines 2-2 of FIG. 1; j
  • FIG. 3 is a sectional view taken along lines 3-3 of FIG. 2; and, I
  • FIGS. 4-6a are schematic plan and sectional views depicting the apparatus in various stages of its operation.
  • the apparatus 10 is shown located adjacent to a pathfl into which individual elongated elements are to be fed laterally.
  • the apparatus includes delivery means in the form of conveyor chains 12, conical rollers 14. and cylindrical skewed rollers 16.
  • the conveyor chains are supported by sprockets (not shown) and are driven continuously in a conventional manner in the direction indicated schematically by the arrow 18.
  • the conical rollers 14 are disposed at an angle with respect to the feed direction 18 of the conveyor chains 12.
  • the rollers 14 are driven by means (not shown) acting through suitable pinion gears contained in housings 20, the latter being interconnected by shafts 22 and couplings 24.
  • the cy lindrical skewed rollers 16 are likewise disposed at an angle relative to the feed direction 18 of the conveyor is disposed at an acute angle in relation to the path P.
  • a second stop member 38 is located between the path P" and the end of the first stop member 34.
  • the second stop member is movable by means (not shown) through a slot 40 in the table apron 32 between a raised operative position as shown in FIGS. 40, 4b and 6a, and a lowered inoperative position as shown in FIG. 5a.
  • a third stop member 42 is fixed at a position downstream from the first stop member 34.
  • the apparatus further includes! a pusher means 44 which is movable laterally relative to the path "P" between an inoperative retracted position shown by the solid lines in FIG. 1 and anadvanced operative position indicated by the dot-dash lines at 44a.
  • the pusher means is operated by a drive (not shown) contained within housing 46.
  • the apparatus may also include a drive means gener' ally indicated at 48 for propelling elongated elements along the path P."
  • the drive means 48 includes a lower bed 50 having short pads 52 which slidably engagerails 54 on an underlying stationary base 56.
  • the bed 50 is movable laterally relative to the path P by means of a screw drive 58.
  • the bed 50 further includes a pedestal 60 on which is mounted an upper support stand 62 for pivotal movement about a transverse shaft 64.
  • a cylinder 66 is pivotally attached to the bed 50 as at 68 and has its extensible piston rod.70 connected to the upper support stand 62 as at 72.
  • the upper support stand 62 carried a horizontally extending roll shaft 740 which is driven through a coupling by a motor 76.
  • a second roll shaft 74b is carried on one end of an adjustable arm 78, the other end of which is keyed to a third shaft which is in turn journalled for rotation at the upper end of a support 82.
  • a crank 84 is alsoattached to shaft 80.
  • crank 84 is con nected as at 85 to the extensible piston rod 85 of a second cylinder 88 pivotally mounted on the upper support stand 62 as at 90.
  • the rollshafts 74aand 74b each have pinch rolls 92a and 92b.mounted thereon. The pinch rolls are shown in the closed "drive" position in FIG. 2.
  • the delivery means (conveyor chains 12, conical rollers 14 and cylindrical rollers 16) have delivered several elongated elements A, and A, to positions abutting theangularlydisposed face 36 of the first stop member 34.
  • Another element A has passed between the first and second stop members 34 and 38 and is at rest against the third stop member 42.
  • a fourth element A is beingdriven along the path P" by the cooperative action of the pinch rolls 92a and 92b.
  • a fifth element A is being carried by the delivery means towards the first stop member 34. As is best shown in FIG.
  • the path P" is clear and ready to accept the nest product length.
  • the second stop member 38 is lowered as indicated in FIG. 5a.
  • the next subsequent product length A is then pushed into the path P" by the pusher 44.
  • the pinch rolls 92a and 92b are again closed by reverse operation of cylinders 88 and 60, thereby exerting a propelling force on the product length A
  • the pusher 44 is immediately withdrawn, and the second stop member 38 is again elevated.
  • each element can be rapidly fed into the path P" as soon as the tail end of the preceeding element has cleared the apparatus. This insures minimum spacing between elements being processed further down the line.
  • the distance between the first and second stops 34 and 38 can be adjusted to accommodate elements of varying width, and the pinch rolls 92a and 921: can be quickly changed to accommodate different cross sections.
  • the apparatus can be rapidly converted to handle other types of products such as for'example flats or rounds.
