Description of the Related Art Conventionally, a fixed quantity supply board is rotatably provided below a hopper, and powder and granules discharged from the bottom surface of a hopper storing the granular material are stored in a fixed quantity supply board constant volume of the granular material storage space. Then, there is known a constant quantity supply device which rotates and discharges it at a required position, and calculates the discharged supply amount based on the number of rotations of the constant quantity supply plate and the volume of the granular material accommodating space. The constant quantity supply device and the hopper are fixedly installed on the floor surface, and their weights are directly supported by the installation floor surface. Alternatively, the fixed amount supply device is attached to the lower portion of the hopper, and the weight of the fixed amount supply device is supported by the hopper. The powder and granular material metering and feeding device of this conventional structure calculates the powder and granular material supply amount from the powder and granular material accommodating space volume and the number of revolutions. May occur, and it was accompanied by error correction work. One of the causes is that the filling condition of the granular material varies depending on the condition of the device, the powder pressure, the installation environment of the device, and the type of powder, and it does not fill as set. Especially. In addition, there is one that separates the hopper and the granular material quantitative supply device as separate devices, but this requires a granular material powder feeding device at the lower part of the hopper in addition to the granular material quantitative supply device. There is a problem in that the apparatus is complicated and a large installation space is required because a powdery or granular material transfer path is required.

り、荷重計による粉粒体供給量計測精度を高める。In the present invention, the powder or granular material in the hopper is discharged from the powder or granular material discharge port at the lower portion of the hopper, is accommodated in the powder or granular material feeding device below the hopper, is fed around the lower portion of the hopper, and is discharged to the outside. It The powder discharge port of the hopper and the discharge part of the powder feeding device are on the line of symmetry, and the structures of the hopper and the powder feeding device are symmetrical to the line of symmetry. In the granular material conveying device, only the granular material in the semicircumferential transfer path from the granular material discharge port to the opposite discharge part is asymmetrical, except that the entire device is symmetric. Therefore, the weights of the hopper, the granular material feeder, and the granular material inside these are supported by two points or linear support points on the line of symmetry and a load cell in between, but Since the powder and granular material in the body conveying device and the hopper are symmetrical with respect to the line of symmetry, these weights are mostly supported by the two supporting points of the extension part. Since the powder particles on the semicircular transfer path in the powder particle feeding device of the present invention are asymmetrically unevenly distributed with respect to the line of symmetry, the powder particles are supported by the load cell at the third supporting point. The load value of the load cell is a value that generates a moment that cancels out the moment around the line of symmetry due to the weight of the powder particles on the semicircular transfer path. Therefore, the weight of the granular material on the semicircular transfer path can be calculated from the measured load value of the load meter, and the amount obtained by multiplying this by the feeding speed of the granular material feeding device becomes the supply amount per hour. The calculation of the weight of these powdery particles and the multiplication by the feeding speed are performed by the powder feeding measuring means, and the supply amount is output. Further, since the discharge of the granular material from the hopper is performed from the granular material discharge port of the partial opening of the lower side wall of the hopper, the weight of the granular material of the hopper is largely supported by the bottom surface thereof, and the large amount of the granular material inside the hopper is generated. The powder pressure is prevented from directly acting on the powder or granular material discharge port to prevent excessive flow of powder or granular material. Furthermore, since the inflow and outflow of the granular material into the granular material conveying device are on the symmetry line, the load fluctuation due to the movement of the granular material can be minimized. In particular, if the inner diameter shape in the hopper and the constituent members of the rotary transfer path of the powder or granular material feeder are substantially concentric around one center on the line of symmetry, point symmetry will result, and the symmetry will be particularly good, and the load meter Improves the accuracy of measuring the amount of powder and granular material supplied.

される。Since the hopper 1 and the granular material conveying device 10 have a substantially symmetrical line structure, the weight of the granular material in the hopper 1, the granular material conveying device 10 and the hopper 1 is the symmetrical line 3.
The load is applied symmetrically with respect to 1. This load is applied to a pair of conical pressure receivers 34 through a pair of support arms 32 provided in the extension direction of the line of symmetry 31, and is point-supported by the pressure receivers 34. The discharge of the discharge chamber 20 is not a little symmetrical, but is on the line of symmetry 31, so that a large moment about the line of symmetry is not generated so much, and a slight correction of the load meter 35 can be used. As described above, most of the weight of the apparatus and the weight of the granular material are symmetric, so that they are supported by the pressure receiver 34 of two point supports on the line of symmetry and the load meter 35 of the third support point.
Is not loaded much. The powder or granular material in the powder or granular material storage space 15 of the powder or granular material supply board 11 is filled only in a semicircular region from the discharge chamber 20 to the powder or granular material discharge port 19, and the remaining semicircular region is powder or granular. Most of the water is discharged through the body discharge port 19, so it is almost empty (see FIG. 3). The weight of the powder or granular material in the powder or granular material storage space 15 is eccentric from the line of symmetry 31, is asymmetric, and is loaded by the load meter 35 so as to cancel the moment around the line of symmetry. The rest is supported by the pressure receiver 34. The load value of the load meter 35 is input to the powder feed amount calculation circuit 36 using a computer, and the average arm of the annular powder-particle storage space 15 and the symmetry line 31 of the load meter 35 are input.
From the arm and the load value from the
Weight of the granular material on the top (Since the granular material storage space 15 is symmetrical around the line of symmetry, if the granular material remains in the returning semicircular area, The actual amount of the discharged granular material, which is offset by the amount of the granular material, is calculated from the equation of the moment equilibrium. This is multiplied by the rotation speed of the powder / particle supply board 11 from the encoder 38 to calculate the instantaneous powder supply amount. The calculated powder amount is displayed on the powder supply amount display 37.

くして且つコンパクトにまとめることができる。As described above, according to the present invention, since the granular material is actually carried by the granular material conveying device and the discharge amount is directly calculated, the granular material from the hopper is calculated. The actual discharge amount can be more accurately measured even if the filling condition of the powder and granular material feeding device changes depending on the powder pressure, the type of powder and granular material, the condition of the machine, and the like. Further, the amount of powder fed can be measured even if the specific gravity of the granular material changes. Furthermore, since the hopper and the granular material conveying device have a symmetrical type structure and the hopper and the granular material conveying device are vertically arranged, the occupied space can be reduced and the device can be compactly assembled. .
