  • the ingots A conveyed in turn into the handling delivering part 10 as arranged in the same direction as shown in FIG. 2 will be now conveyed out onto the turntable 6 as in FIGS. 4E and 4F.
  • the limit switch e When the rod 72 of the operating cylinder 7 has reached the extremity of the extension, the limit switch e will be operated so that the turntable 6 may fall by the height corresponding to one step of the ingots A. When this fall ends, said turntable 6 will be rotated by so as to be ready to receive the next ingots.
  • the details of such operation of the turntable 6 are made by the light projector k and such detecting means I as a phototransistor.
  • the fourth oil pressure type operating cylinder 8 will not operate but, when this light is intercepted, by the instruction of the detecting means I, the operating rod 82 of this operating cylinder 8 will contract by one step so that the turntable 6" will first fall by one step corresponding to the height of the ingot. Anyhow, the moment the light of the light projector k is received, the fall of the turntable 6 will stop. Therefore, when the ingots A are not conveyed onto the turntable 6, the rail-shaped supporting seats 61 will stop in a state coinciding with the surface of the rollers 51 of the reciprocating roller base 5.
  • the ingots A are conveyed onto the turntable 6, they will stop in a state that their uppermost surface coincides with the surface of the rollers 51.

  • the limit switch m will be operated to stop said operating cylinder I07 and at the same to switch over the pressure source of the above mentioned fourth operating cylinder 8 so that the rod 82 may be extended to pull up the turntable 6.
  • the turntable When the turntable has reached theextremity of its rise, it will stop by operating the limit switch f, will be at the same rotated by 90 and will stop with the direction of its supporting seats 61 at right angles with the direction of the reciprocating roller base so as to be ready for the next handling delivering cycle.
