In order to lower a predetermined number of rod bodies to the plurality of slits 17, after temporarily stopping on each slit 17 and opening the opening / closing gates 9, all rod bodies of the opening / closing gates 9 are lowered to the respective slits 17. , Drive device 20, air cylinder. The piston is returned in reverse and it returns to the initial state. The next cycle is started by discharging the rod 2 from the conveyor 1 as in the previous cycle.

According to the present invention, in the rod arranging device as described above, a stopper with a shock absorber is provided at the rod stop position of the belt conveyor so that the cushion can be adjusted according to the size of the rod. That is, as shown in FIG. 1, the conveyor belt 23 is stretched between a drive pulley 24 driven by a geared motor 26 and a driven pulley 25, and a stopper 28 is arranged near the end of the belt conveyor 23. This is attached to the piston rod of the air cylinder 27 with a pressure adjusting valve. The stopper 28 is made of rubber, but is not limited to the stopper with a pneumatic shock absorber as described above, but may be a spring type shock absorber with adjustable spring pressure or a hydraulic shock absorber, and an arbitrary shock. An absorber is used.

According to the present invention, as described above, the belt conveyor 23
Since a stopper 28 of a pneumatic shock absorber with a pressure adjusting valve is provided near the end of the, the rods conveyed one by one on the belt conveyor 23 hit the stopper 28, but the shock is generated by the shock absorber 28. Since it is absorbed, it is not returned in the direction opposite to the conveying direction, the rod is positioned at the regular position, and the rod 2 can be dropped into the slit 7 by the above-mentioned dispensing device 5 thereafter. Therefore, the capability of the equipment will not be lowered without extending the supply time of the rod 2 to the rod array supply device. With the conventional fixed stopper provided on the belt conveyor, the speed of the belt conveyor is 50 m / mi.
If n, the reverse return distance of the rod is 500-1000mm
However, in the present invention, when a cylinder having a diameter of 50 ¢ and an air pressure of 2 kg / cm ² is used, a reverse return phenomenon is caused.
