Only when carrying out the narrow flat bar 1, they are separated from each other by a certain distance, and when carrying out the wide flat bar 1, they are integrally connected by a connecting means (not shown). In FIG. 1, reference numeral 57 denotes a phototube-type steel material detection device provided along the downstream end of the chain conveyor 5.

Hereinafter, the effects of the above configuration will be explained. First, the procedure for stacking narrow flat bars 1 will be explained. In FIG. 1, when the flat steel 1 is carried in the direction of arrow A by the carrying-in roller conveyor 2 and stopped at a predetermined position, the steel material carrying-in device 4 shown in FIG.
The parallel link 15 of is triggered by a drive device (not shown), the horizontal guide rail 14 and the loading truck 16 are raised, and the flat bar 1 is lifted by the loading truck 16. Next, one of the sprocket wheels 18 is rotated in one direction by the drive device, thereby moving the carry-in cart 16 on which the flat bar 1 is placed in the direction of arrow C via the chain 17.
Next, the flat steel 1 on the carry-in cart 16 is moved to the chain conveyor 5.
When it is brought to the upper predetermined position, it is detected by the detection device 57, and the detection signal causes the rotation of the sprocket wheel 18 to be stopped and the parallel link 5 to be pulled down. With this, flat steel 1
is placed on the chain conveyor 5. Next, the piston rod of the first cylinder 25 is reduced, and the pusher body 22 in the state shown in FIGS. The steel material receiving cart 8 is pushed out onto the tip end 8A of the steel material receiving cart 8 that is waiting above the steel material receiving cart 8. Here, the table 7 is raised by the extension of the piston rods of the second and third cylinders 33 and 34, and the tip of the intermediate stopper 10 is projected upward from the upper surface of the tip 8A by the fifth cylinder 42. As a result, the extruded flat steel 1 hits the intermediate stopper 10 and is stopped. Next, when the steel material receiving cart 8 is moved in the direction of arrow C by the fourth cylinder 39, the tip portion 8A is pulled out from below the flat steel 1, and the flat steel 1
is dropped onto the center of the table 7 as shown in FIG. 12b. At this time, the steel material receiving cart 8 is guided by the inclined rail 37 and is moved in the direction of arrow C while gradually descending, so that the tip portion 8A
Similarly, as it is pulled out while gradually descending, the sliding friction with the lower surface of the flat bar 1 becomes small. Next, the intermediate stopper 10 is lowered and the steel material receiving cart 8 is moved in the direction of arrow D, so that its tip 8A is brought above the table 7 again as shown in FIG. 12C. Next, the flat bar 1 is pushed onto the tip portion 8A using the pusher claw 24 in the same manner as described above. At this time, since the intermediate stopper 10 is lowered, the flat bar 1 moves until it hits the fixed stopper 9, as shown by the imaginary line C in FIG. Next, when the steel material receiving cart 8 is moved in the direction of arrow C, the flat steel 1 falls onto the edge of the table 7,
The state shown in FIG. 12d is reached. Next, by operating the third cylinder 34, the table 7 is lowered by an amount corresponding to the thickness of one sheet of flat steel 1. Thereafter, by repeating the same operation as described above, the flat bars 1 are stacked one after another on both flat bars 1 of the table 7. Next, when a predetermined number of flat bars 1 are stacked in two rows on the table 7 as shown in FIG. Raise 7 to the highest level.
Next, after aligning the end faces of the stacked flat bars 1 by moving the movable parts of the pair of end face aligning devices 12 closer to each other, the sixth
The cylinder 49 is actuated to cause the parallel link 47 to raise the carrying cart 50 with the front half 50A and the rear half 50B in contact with each other.
0 lifts the stacked flat bars 1. Next, one of the sprocket wheels 55 is rotated in one direction, thereby moving the carrying truck 50 in the direction of arrow C via the chain 54. Then,
First, only the front half 50A is moved, and then the rear half 50B is also moved via the connecting link 53, so that a certain distance is created between the front half 50A and the rear half 50B, as shown by the solid line in FIG. , will continue to move in this state. Next, as shown in the imaginary line in Fig. 13, the flat bars 1 are stacked on the front half 50A.
When the flat bar 1 is brought above the roller conveyor 3 for carrying out, the parallel link 47 is pulled down and the flat bar 1 is placed on the roller conveyor 3 for carrying out. Next, by the operation of the conveyor 3, the flat steel 1 placed on it
is carried out in the direction of arrow B. Next again parallel link 4
7, the unloading cart 50 is moved in the direction of arrow C, and the stacked flat bars 1 on the rear half 50B are brought onto the unloading roller conveyor 3. Thereafter, the stacked flat bars 1 may be carried out in the direction of arrow B in the same manner as described above.

Next, when stacking wide flat bars 1, the first
With the intermediate stopper 10 lowered as shown in Figure 4a, the stacking operation is performed using only the fixed stopper a, and the flat bars 1 are stacked on the table 7 as shown in Figure 4b. In addition, when carrying out, the front half 50A and the rear half 50A of the carrying cart 50 are
B shall be fixed so as not to be separated from each other.

Effects of the invention As described above, according to the invention, in the case of wide flat steel, it is possible to stack the flat steel in a single row on the table by lowering the intermediate stopper and using only the fixed stopper. . In the case of narrow flat bars, the fixed stoppers and intermediate stoppers can be used to stack the flat bars in two rows on the table, thereby increasing the conveyance speed. Furthermore, during stacking, the steel material receiving cart can be moved to a predetermined position while gradually descending under the guidance of the inclined rail, and this allows it to be pulled out while gradually descending against the flat steel. It is possible to reduce the sliding friction in the sliding contact area, reduce damage caused by sliding contact, and reduce the moving force of the steel material receiving cart.
