量を算出する方法も或る。(Prior art) Conventionally, a rotating body with a cell space formed on its outer periphery is provided with an input section for introducing powder and granular material into the cell space above one side, and a discharge section for the powder and granule material is provided approximately on the opposite side. A feeder is widely used, which is a type of fixed-quantity feeder that charges powder into a chamber space, moves it to a discharge section as a rotating body rotates, and discharges it to the outside from the discharge section. The method of calculating the amount of powder or granular material supplied by this type of quantitative feeder is the volume of the cell space (total volume), the number of revolutions, and the specific gravity of the cell (the weight of the powder or granular material filled in a unit volume).
A widely used method is to calculate the value multiplied by . Alternatively, calculate the weight of the powder or granule by measuring the weight of the entire metering feeder including the powder, subtracting the weight of the fixed metering feeder itself from this measured weight, and multiplying this by the rotation speed. There is also a method of calculating the supply amount as a value.

た。(Problem to be solved by the invention) In this type of quantitative feeder, the powder and granules in the cell space of the rotating body are not completely discharged at the discharge section, and some of the powder and granules adhere to the cell wall surface. After returning to the department, the next batch of powder and granular material was being filled. As a result, the amount of powder and granules actually discharged at the discharge section is lower than the weight value calculated above, resulting in a problem of small errors.

The weight of the entire powder feeder including the rotating body 1 is measured in a distributed manner by three weight measuring instruments. The rotating body 1 has radial blades 15 protruding from its outer periphery, and a square space 16 is formed between the blades and the case 11. The load acting on these two sets of weight measuring devices is the weight distribution of the powder feeder itself, as shown in Figure 5.
A distributed load c is added to (a) due to the amount of granular material in the transfer path (b) and the amount of granular material adhered to the return path, and is measured as a corresponding load by each weight measuring device.

ない。 In this embodiment, first, the total sum Wf of the weight values measured by the weight measuring devices 3, 5, and 6 in a state where the entire square space 16 of the rotating body 1 is filled with powder or granular material is determined. This weight Wf is the weight 2w 1 of the powder and granular material filled in the entire cell space 16, and the overall weight W of the device including the rotating body 1 itself, the case 11, the discharge chute 10, the drive motor 12, and the attached parts attached to these. The sum with 0 is 2w 1 +W 0 . One example of a method for measuring the weight Wf is to attach a weighed sheet that closes the discharge section 8 without rotating the rotating body 1, fill the entire square space with powder, and then use a weight measuring device to measure the weight. It can be found by measuring and subtracting the sheet weight from the total. The method of measuring Wf is not limited to this.

る。 To calculate the supply amount during operation when the rotating body 1 is rotated, the total sum W of the weights measured by the weight measuring devices 3, 5, and 6 at each time is determined. This sum W is the weight of powder particles filled in the cell space 16 portion of the transfer path 2 and the return path 4.
The weight of the powder adhering to the square space 16 of the rotating body 1
It is the sum of w 2 and the total weight of the device W 0 mentioned above.

w 2 )・N can be calculated. These are performed by a calculation circuit 13 using a computer or the like. The resulting powder supply amount is displayed on the supply amount display 14.
