ンテナンス費も増え、経済的に不利になる。By the way, the trough-type steel bar transfer device according to the above-mentioned conventional example is of a four-line type, as can be clearly understood from FIG. Therefore, for example, when the productivity is to be doubled, the eight-line system may be used. However, not only is the bar and bar delivery apparatus itself very large, but also the drop height of the bar is increased. .
In other words, when the drop height of the steel bar (it is considered to be preferably within 1 m) increases, the steel bar bends due to the impact at the time of dropping, and the groove is shifted by repulsion due to repulsion, resulting in deterioration of quality. It is not preferable. In addition, when the bar and bar delivery system becomes large, its structure becomes complicated, maintenance costs increase, and it becomes economically disadvantageous.

Can be dropped at predetermined time intervals, so that it is not necessary to increase the size of the steel bar delivery device 1, and the steel bar B can be dropped at the same cooling height as the conventional steel bar delivery device. Can be dropped to a fixed position.
As well understood from the comparison between FIG. 1 and FIG. 8, the configuration of the steel bar delivery device 1 and the conventional steel bar delivery device are almost the same, and the maintenance cost increases in accordance with the number of processed steel bars. Since there is no steel bar, it can greatly contribute to a reduction in cost per unit processing of the steel bar.

As is well understood in comparison with FIG. 1 showing the first embodiment, two trough-shaped steel bar receiving portions for receiving hot-rolled high-temperature steel bars sent from a transporting unit (not shown). The rocking arm 3 having the upper and lower rocking arms 2 and 2a has a two-stage structure consisting of only two upper and lower arms.
The fixed rake bar 2 of the cooling floor 20 is guided by one steel bar drop guide 11 formed between the outer guide 13 and the outer guide corresponding to the intermediate guide 14 of the first embodiment.
This is configured to be dropped into the first receiving groove 21a, and otherwise has the same configuration as the steel bar delivery apparatus according to the first embodiment.

調整作業を行わなければならない。By the way, in order to deliver a small-diameter steel bar B having a diameter of 10 mm or less, the steel bar B is dropped only from the steel bar receiving portions of the lower two rocking arms of the four rocking arms. I couldn't let it. That is, since the steel bar B having a diameter of 10 mm or less is flexible like a rope, for example, the steel bar B largely bounces and shifts when colliding with the receiving groove 21a of the fixed rake bar 21 of the cooling floor 20 (the groove shift is kept as it is). And the steel bar would bend.) In order to prevent the groove from shifting, it is only necessary to adjust the interval between the steel bar drop guides, but it has been extremely difficult to adjust the interval between the steel bar drop guides. For example, in FIG. 1, No.
2, No. 3, No. In the case of No. 4, conventionally No. 1
And No. 3 or No. 2 and No. Since four steel bars are simultaneously received in the steel bar 4, all of the four transport lines must be used, and a difficult work of adjusting the interval between the bar steel drop guides is required.

The same steel bar delivery capability as when using a steel bar delivery device can be exhibited.

In addition to the effect equivalent to 1, the steel bar B is removed from the steel bar receiving portion 2 on the distal end side, and from the position of the rocking arm 3 where the steel bar B falls down from the chute 9, the steel bar receiving portion 2a on the rocking support shaft 4 side Since the rocking angle of the steel bar B to the position of the rocking arm 3 at which the steel bar B comes off from the steel bar receiving portion 2a and falls down on the chute 9 becomes smaller than in the case of the steel bar transfer device according to the first embodiment, There is an effect that the falling height of B can be reduced.

The rocking angle up to the position of the rocking arm 3 where the steel bar comes off from the steel bar receiving portion 2 and falls down from the chute 9 is:
Since it is smaller than in the case of the steel bar delivery device according to the first embodiment, the same effect as in the second embodiment can be obtained, in which the falling height of the steel bar B can be reduced. In the fourth embodiment, the shape of the stopper member 8 is a half-cylindrical cylinder, but for example, FIG.
As shown in (b), since the shape of the stopper member 8 can be formed into a mountain shape obtained by dividing the rectangular cylinder into two by a line passing through the apex angle, the sectional shape of the stopper member 8 is particularly limited. Not something.

According to the method for delivering steel bars to the cooling floor and the apparatus for delivering steel bars to the cooling floor according to the above-described embodiments 6 to 6, the steel bars received by each of the plurality of steel bar receiving units are dropped from the same chute at predetermined time intervals for cooling. Since the steel bar can be dropped to a fixed position on the floor, despite the increase in the ability to transfer the steel bar to the cooling floor, an increase in the size of the steel bar delivery device is suppressed, and the drop height of the steel bar is prevented from increasing, In addition, it is possible to suppress an increase in maintenance cost of the steel bar transfer device. Therefore, there is a great effect that it is possible to contribute to the productivity of the steel bar having the quality within the standard and the cost reduction of the product.
