1) The cylinder 22 of the weighing machine 20 is operated and the weighing unit 2
1 is raised (S2), and the measuring container 2 is placed on the weighing section 21. Next, the drive unit 13b of the opening / closing plate 13 operates to open the outlet of the large powder passage 12c (S3), and holds the powder discharge port 11a half open (S4). The device 12a is operated (S5). Thereby, the granular material 1 is supplied from the granular material supply device 10 to the measuring container 2. At this time, when the granular material 1 discharged from the tank 11 of the granular material supply device 10 is received by the carry-out feeder 12, the large granular material 1a of the granular material 1 is separated from the granular material separation plate in the carry-out feeder 12. The small particles 1b are not guided through the large particle passage 12c and cannot pass through the small particles 12b, and are guided to the small particle passages 12d through the granular material separation plate 12b. Through the measuring container 2. When the measured value of the weighing machine 20 reaches the value before the set amount (S6), the drive unit 13b of the opening and closing plate 13 is operated to close the outlet of the large powder passage 12c (S7). Thereby, thereafter, only the small particles 1b in the small particle passage are supplied to the measuring container 2, and when the measured value of the weighing machine 20 reaches the set amount (S8), the vibration generator 12a of the unloading feeder 12 is stopped. Then, the weighing unit 21 of the weighing machine 20 is lowered (S10).

６に戻る。By the way, during the supply of the powdery material,
When there is an extremely large lump of granular material in the tank 11 of the granular material supply device 10, the lump of granular material may be clogged in the granular material discharge port 11a, which may hinder the release of the granular material 1. . Therefore, in such a case, the above situation is solved by the following operation. That is, if the rate of increase in the weight of the granular material 1 supplied to the measuring container 2 decreases after the supply of the granular material 1 is started until the measured value reaches the set amount (S11), the flow rate adjustment is performed. The drive unit 14a of the plate 14 is operated to fully open the powder material discharge port 11a (S12). As a result, the lump of granular material clogged in the granular material discharge port 11a is discharged to the carry-out feeder 12, and after waiting for a time (S1).
3) If the rate of weight increase has risen (S14), the granule discharge port 11a is half-opened (S15), and the process returns to step S6. In addition, if the clogging of the granular material mass is not eliminated by such an operation and the increase in the weight increase rate is not observed in step S14, the driving unit 14a of the flow rate adjusting plate 14 is operated to operate the flow rate adjusting plate 14. Reciprocate continuously (S1
6). As a result, the mass of the granular material clogged in the granular material discharge port 11a is pulverized by the flow rate adjusting plate 14, and the clogging of the granular material discharge port 11a is eliminated. Then, after the granular material discharge port 11a is half-opened (S15), step S is performed again.
Return to 6.

計量装置にも適用することが可能である。As described above, according to the granular material weighing apparatus of the present embodiment, the large granular material 1a composed of the granular material mass having a predetermined size or more is placed in the large granular material passage 12c and the other small granular material 1b is placed therein. When the measured value of the weighing machine 20 reaches a predetermined amount before the set amount, the large particle passage 12d is separated.
Since the outlet of c is closed to supply only the small particles 1b of the small particle passage 12d to the measuring container 2, even if a part of the powder 1 is agglomerated, it can be used immediately before the set amount. The mass of the granular material is not supplied to the measuring container 2, so that a measuring error can be reliably prevented. In the weighing machine 20, the weighing unit 2 is placed on the weighing container 2 stationary on the conveyor 3 from below.

In addition to the effect of claim 1, a large powder mass in the tank
Even if clogging occurs in the powder discharge port,
Collected powder mass can be discharged to the unloading feeder
The advantage is that it does not hinder the release of powder
There is.

きる。 According to a third aspect of the present invention, there is provided a powdery and granular material measuring apparatus.
Thus, in addition to the effect of the second aspect, the opening degree of the granular material discharge port is increased.
If clogging of the granular mass does not clear even after
It is possible to break up the granular mass that is clogged in the body discharge port
As a result, clogging of the granular material discharge port can be reliably eliminated.
Wear.
