Box (
The shot material fed into the box 2) is naturally fallen in the form of a band by the shot material cutting mechanism (3), and is also diffused in the direction of the duct (7) by the airflow (Wl) flowing inside the box (2). Among the dispersed projectile materials, those with large particle size are sorted by the chute (4) and sent to one of the two forks (2) of the box body (2).
The shot material falling into one of the two branches (2a) contains some particles of small particle size. The shot material that has fallen into one of the two branches (2a) is sent into the shot material storage tank (9) via a transport pipe (not shown).
On the way, a part of the shot material is taken out by switching the switching gate (8) and sent to the first vibrating sieve machine Cl0). The shot material fed into the first vibrating sieve machine Cl0) is
Small particles are classified by the vibrating sieve (10) and sent to the discharge port (
After being discharged from 10a), the particles are first stored in a hopper (not shown), and after large particles are discharged from the discharge port (10b), they are stored in another hopper (not shown). Next, the large and small particle diameter projectile materials stored in each hopper are sequentially fed into a weighing scale C11) and weighed, and the measured value is input to the control device (15) to The weight ratio of the particle size shot material and the large particle size shot material is calculated. The actual weight ratio calculated in this way is compared with a preset setting value, and if the actual weight ratio is larger than the setting value, the electric damper (7) is driven to increase the opening degree, and as a result, the above-mentioned The dispersion state of the naturally falling projectile material is more diffused towards the (6) side, and after that, it becomes one of the two forks (2).
In (a), the shot material (c, which has a higher particle size than before) will fall. Further, when the actual weight ratio is smaller than the set value, the electric damper (7) is driven to reduce the opening degree as necessary.
