Definitions

  • the invention relates to conveyors for elongated rolled stock such as tubes, and relates more particularly to such conveyors for use in connection with cooling pits or adjusting machines for the rolled stocks; still more particularly, the invention in at least some of its aspects relates to an automatic distributing machine for the rolled stock.
  • FIG. 1 is a schematic plan view of the transport mechanism for elongated rolled stoclc' including a cooling bed
  • FIG. 2 is a large scale fragmentary elevational view thereof
  • FIG. 3 is a plan view of the distributing machine
  • FIG. 4 is a plan view of a side bed.
  • a cooling bed that includes screw conveyors and comprises an upper bed 1, a lower bed 2, and a side bed 3 adjacent the lower bed 2.
  • the lower bed 2 is formed as a machine for distributing the rolled stock, while the side bed 3 (FIG. 4) serves to take over and to convey the elongated tubes and therefore is provided with two conveyor tracks or paths which may lead, for instance, to two straightening machines 4.
  • the rolled stock in the ensuing description is identified as elongated hollow tubes.
  • a stationary circular saw 5 that cuts the tubes, for instance in half.
  • the halved tubes are conveyed by the distributing machine in the rhythm of the work operation onto the side bed 3 in accordance with a distribution pattern, for instance in such a manner that each halved tube will be conveyed to its respective straightening machine 4.
  • the distributing machine 6 is arranged below the upper bed 1 and, between the upper bed 1 and its transport machine and the distributing machine 6, there is provided a tiltable connector, such as a rost 7 which is tiltable between a position shown in FIG. 2 in solid lines, wherein the tubes are conveyed to the distributing machine 6 and, respectively, a second position shown in FIG. 2 in broken lines wherein the tubes are conveyed towards a discharge conveyor 8.
  • a tiltable connector such as a rost 7 which is tiltable between a position shown in FIG. 2 in solid lines, wherein the tubes are conveyed to the distributing machine 6 and, respectively, a second position shown in FIG. 2 in broken lines wherein the tubes are conveyed towards a discharge conveyor 8.
  • the distributing machine shown in FIG. 3 comprises a frame that includes a series of paired screw conveyors 9.
  • the conveyors 9 are provided with threads that have similar shape and twist so that, as shown in FIG. 2, upon rotation in the same direction the conveyors will move the elongated rolled tubes parallel to themselves.
  • Transportation of the tubes by the conveyors 9 will result in movement of the tubes in a composite direction, namely, in the direction of a first component longitudinally of the tubes (for instance to the right, in FIG. 3) and, respectively, in the direction of a second component at right angle to the first component (for instance upwardly, in FIG. 3).
  • Transport rolls 10, 11 and 12 are furthermore provided, and each transport roll is disposed between two conveyors 9 of each pair of conveyors 9.
  • the axes of all the screw conveyors 9 are disposed in a horizontal plane, and are parallel, and likewise the axes of the transport rolls are in the same horizontal plane and are parallel to the axes of the screw conveyors 9.
  • the transport rolls 10 which are disposed in the region of the second half of the halved tubes are each provided with two outer cylindrical surfaces of different diameters, the surfaces of each diameter extending for about onehalf the length of the transport roll.
  • initial transport rolls 11 which have two cylindrical surfaces of dilferent diameters, but these surfaces are distributed over the length of the transport roll in accordance with an unequal ratio.
  • the remaining transport rolls 12 are provided with only a single cylindrical surface throughout their entire lengths.
  • All the screw conveyors 9 rotate with the same angular velocity, and all the transport rolls rotate with one angular speed, butthe angular speed of rotation of the transport rolls may be different from that of the screw conveyors 9.
  • the direction of rotation is the same for all the screw conveyors 9 as well as for all the transport rolls 10, 11 and 12.
  • each tube will be moved in an inclined path of transportation until the tube has come into the region of the surface of larger diameter of a transport roll 10.
  • the larger diameter of the transport roll 10 is so dimensioned that the larger surface of the transport roll will make contact with the external surface of the tube suspended thereabove, so that upon such contact the tube will receive additional acceleration in the direction of its longitudinal extension (to the right, in FIG. 3). This will change the angle of inclination of the composite direction in favor of the component in the direction of the longitudinal extension of the tube.
  • the sole diameter of the transport rolls 12 is so dimensioned that, like the large diameter of the rolls 1%, contact will be made between the transport rolls 12 and the tubes suspended thereabove.
  • the first tube halves (shown to the right of center, in FIG. 3) are suspended over the transport rolls 12, and, owing to the large single diameter of the rolls 12, will at once receive the aforesaid additional acceleration in the direction (to the right, FIG. 3) of the longitudinal extension of the tubes.
  • the first tube halves will be transported much faster to the right (FIG. 3) than the second tube halves, as a comparison between the portions to the left of cen ter and to the right of center of FIG. 3 reveals.
  • transport rolls 1i) and 11 were described as having only two different types of surfaces, it is instead entirely possible and comprised in the scope of the invention, to provide transport rolls with three or more sub-divided surfaces in accordance with different stepped diameters.
  • the invention provides by way of exemplification that each tube half is being transported to a different straightcning machine 4.
  • the adjoining side bed 3 requires a special construction.
  • the side bed 3' receives the tube halves which are conveyed by the distributing machine of FIG. 3.
  • the side bed 3 has two tracks, each for one of the tube halves, and each track terminates in one of the abutments 13 and 14, respectively.
  • transport rolls 15 and 16 are provided with transport rolls 15 and 16, with stepped external diameters similar to the transport rolls 10.
  • the transport rolls 15 and 16 only partly serve for acceleration and partly serve for retardation of the linear speed of the tubes in their longitudinal direction.
  • Screw conveyors 17 and 18 are provided, as shown in FIG. 4.
  • the instant system by way of exemplification, has been shown as being arranged in a cooling pit, but it may instead be arranged in an adjusting device, or in still different surroundings.
  • the instant system renders it possible to distribute automatically with simple means elongated rolled stock in accordance with a predetermined distribution plan.
  • the instant invention offers the advantage of automatic operation in step with the remainder of the rolling operation, avoiding the previously experienced stalling and operational disturbances.
  • a transport mechanism for elongated rolled stock comprising an upper transportation cooling bed, a lower transportation cooling bed disposed adjacent, though in a plane lower than that of, said upper cooling bed, and an elongated distributing machine disposed adjacent said lower bed at right angles to the transportation direction of both said beds, the lower of said beds and machine comprising a frame, a plurality of thread carrying screw conveyors and transport rolls journalled on said frame, the axes of rotation of said conveyors and rolls being parallel to each other and in the same horizontal plane, the threads of said conveyors having similar shape and twist, each transport roll being disposed between the two conveyors of each pair of conveyors and having at least one outer cylindrical surface, means operable for rotating said conveyors and rolls in the same direction of rotation, at least some of said transport rolls extending throughout a major portion of the length of said screw conveyors, whereby rolled stock supported on said screw conveyors will be moved in a composite direction COITlposed of a first component in the longitudinal direction of the rolled stock and a second component at right angle thereto,
