Further, the divided granular material dropping means 3A is fixed with respect to the rotation of the granular material equal dividing means 3, and each of the granular materials equally divided by the granular material equal division means 3. Are sequentially dropped to the side of the measuring powder / grain separation means 4.

Further, the weighing and granular material separating means 4 comprises a rotating shaft 8
Is rotated at the same speed as the powder / granular material dividing means 3 in accordance with the rotation of No. 3, and the powder particles to be weighed are distinguished from those not, and the former powder particles are rotated. Axis 8
While dropping from the position in the vicinity of, the latter powdery particles are dropped from a position separated from the rotation axis.

Further, the weighing and granular material accommodating means 5 is arranged around the rotating shaft 8 and can accommodate only the granular and granular material to be weighed which is dropped from the weighing and granular material separating means 4. . The powder or granular material stored in the measuring powder or granular material accommodating means 5 is weighed by the load cell 6, and thereafter, it can be dropped through a hole provided in the bottom of the measuring powder or granular material accommodating means 5.

Here, the granular material which does not need to be weighed from the measuring granular material separating means 4 falls around the measuring granular material accommodating means 5, and the measuring granular material accommodating means 5 is provided.
It is designed to be transferred to the next step, for example, a bag-filling step, together with the weighed powder particles from

In the hopper 1, the shutter 2 for preventing the powder or granular material from dropping from the powder or granular material dividing means 3 when the powder or granular material is not a desired measured value by the measuring powder or granular material storage means 5.
Is provided.

Next, the powder / granular material dividing means 3 provided in the powder / granular material dividing device having such a structure, the divided powder / granular material dropping means 3A, the weighing powder / granular material separating means 5, and the weighing powder. Each of the grain accommodating means 6 will be described in detail with reference to FIG. 1 (axial exploded perspective view).

Particulate material equal dividing means 3 A first wall portion 3a concentric with the rotary shaft 8 and a plurality of second wall portions 3 extending radially from the rotary shaft 8 at equal angles.
b and an intermediate plate 3c arranged between the weighing and granular material separating means 4 and fixed against their rotation.

As a result, the granular material dividing means 3 has a plurality of dividing chambers, and the continuous granular material drops from the hopper 1 (arrow α) and the granular material dividing means 3 rotates at a constant speed. By doing (arrow A), equal amounts of powdery or granular material are stored in each of the division chambers.

Divided granular material dropping means 3A In the intermediate plate 3c, one granular material falling hole 3d is formed in a region corresponding to one divided chamber of the granular material dividing means 3. There is.

As a result, following the continuous drop of the powder or granules from the hopper 1, the divided powder or granules are sequentially dropped to the weighing powder or granule separating means 4 side through the powder or granule drop hole 3d. Will be.

Weighing powder and granules separating means 4 The first and second wall portions 3a and 3b of the powder and granular material dividing means 3 are arranged at positions corresponding to the extended positions of the first wall portion 3a and the second wall portion 3b.
It has a plurality of division chambers defined by the wall portion 4a and the second wall portion 4b, one of which is the measurement division chamber 4A.
The metering division chamber 4A is provided with a guide plate 4X for guiding the powder particles that have fallen through the powder particle dropping hole 3d to a position close to the rotary shaft 8 and dropping the powder particles. A guide plate 4Y that guides and drops the powder or granules that have fallen through the powder or granular material drop holes 3d into the respective separation chambers other than the measurement division chamber 4A to a position away from the rotary shaft 8 is dropped. Is provided.

That is, the guide plate 4Y has a reverse inclination with respect to the guide plate 4X, and when the weighing and granular material separating means 4 rotates (arrow A), the granular material dropping hole 3d.
When a division chamber other than the measurement division chamber 4A is positioned immediately below, as shown in FIG. 3, the powder or granular material falling from the powder or granular material dropping hole 3b is guided to the guide plate 4Y and weighed. It is designed so as to fall from the periphery of the granular material separating means 4.

In the above structure, the weighing division chamber 2
The second wall portion other than the second wall portion 4b defining A does not necessarily have the necessary configuration, and may be omitted.

A container constituted by a rotary shaft 8 of the measuring powder and granular material storage means 5 , a concentric wall portion 5a and a bottom plate 5b, which is fixed with respect to the rotation of the rotary shaft 8. There is.

The weighing and granular material accommodating means 5 is to be weighed, that is, the granular and granular materials falling from the position close to the rotary shaft 8 among the granular and granular materials falling from the weighing and granular material separating means 4. The container has a diameter capable of storing only powder and granules.

For this reason, the granular material falling from the position separated from the rotary shaft 8 is designed to drop around the container.

The powder particles thus stored in the container are measured by the load cell 6, and the measured value is the powder particles having the volume divided by the powder particle equalizing means 3. It has become that of the body.

In addition, the weighing powder and granular material accommodating means 5 has a hole 5c formed in a part of the bottom plate of the container, and a fin 5d fixed to the rotary shaft 8 and extending to the side wall of the container.
It has.

With this structure, the weighed powder particles are automatically dropped through the hole 5c as the rotary shaft 8 rotates.

According to the powder / granular material equalizing device constructed as in this embodiment, one of the powder / granular materials equally divided by the powder / granular material dividing means 3 is directly used as the weighing powder / granular material storing means 5
Since the measurement is conducted by being guided to, it is possible to measure the divided granular material as it is.

Since the measured powder and granules can be automatically measured every one revolution of the powder and granules dividing means 3, frequent measurement can be carried out.

Further, since the measuring powder and granules accommodating means 5 is arranged to drop the measuring powder and granules in the same direction as the powder and granules which do not require measurement, the powder which does not require measurement. It becomes possible to move to the next step as it is like the granules.

In the above embodiment, the weighing division chamber 4
The guide plate 4X in A has an inclination that guides the falling powder and granular material to a position close to the rotating shaft 8, but has an inclination that guides it to a position separated from the rotating shaft 8. It goes without saying that it is good. However, in this case, the guide plates 4Y in the division chambers other than the measurement division chamber 4A need to be inclined so as to guide the powdery particles to a position close to the rotation shaft 8.

The container in the weighing powder and granular material accommodating means 5 has no choice but to have an annular shape, but this does not particularly cause a problem.
