In the whole descending process, the built-in brake and the disc brake 11 of the main transmission motor 10 are always in the alternate action state of clasping and releasing, the damage to equipment and bars caused by the rapid descending of the bar rolled pieces is prevented until the bar rolled pieces are located in the detection reaction area of the proximity switch 40, the proximity switch 40 detects position signals of the bar rolled pieces and transmits the signals to the encoder 14 and the brake 11 of the main transmission motor 10, the brake 11 rapidly brakes after receiving the signals of the proximity switch 40, the control plate type chain 26 stops acting, and the bar rolled pieces fall between the U-shaped vertical rollers of the conveying unit 60. Then, the motor of the conveying unit 6 operates to drive the flat roller 60 to work, and the flat roller 60 transports the bulk-bound rods to the next process. When the bar rolled piece leaves the plate-type chain 26, the encoder 14 controls the main transmission motor 10 to rotate reversely, the main transmission motor 10 drives the plate-type chain 26 to ascend, the plate-type chain 26 returns quickly, when the position of the plate-type chain 26 is close to an initial position area signal sensed by the switch 40, the proximity switch 4 transmits the signal to the encoder 14, and the encoder 14 controls the main transmission motor 10 and the brake 11 to brake simultaneously, so that an action period of conveying the bar rolled piece is completed.
When the rolled bar materials rolled to the plate-type chain 26 are sufficiently bundled, the air cylinder 30 starts to work and extends out of the output end, the air cylinder 30 drives the rotating arm 31 to rotate, and the rotating arm 31 rotates and drives the rotating shaft 33 to rotate. The rotating shaft 33 rotates to drive the blocking arm 32 to move, the blocking arm 32 prevents the bar rolled piece from continuing to roll onto the plate type chain, the purpose of stopping the plate type chain 26 to continue to receive materials is achieved, automatic control is achieved in the whole process, and working efficiency is improved.
