いる。2. Description of the Related Art This type of constant flow dispensing device is constructed as shown in FIGS. 7 and 8. The hopper 1 is supported from the fixed side B via a weighing device 2, and the control unit 3 controls the hopper 1 so that the decrease value per unit time of the weight value of the weighing device 2 becomes the target flow rate. The opening degree of the gate device 5 attached to the bottom opening 4 as a dispensing port of the hopper is controlled.
It is configured such that a constant flow rate of raw material 6 is dispensed from 1.

問題がある。Problems to be Solved by the Invention In such a conventional configuration, when the gate plate 7 starts to be opened, it gradually opens from the end of the bottom opening 5, as shown in FIG. paid out. At this time, since the width of the raw material discharge port spans the entire width of the bottom opening 4, fine adjustment is not possible unless the amount of rotation of the gate plate 7 is controlled by minute driving. Furthermore, even if the amount of rotation of the gate plate 7 can be controlled by micro-drive, the dispensing port increases or decreases over the entire width of the bottom opening 4, so even if the resolution of the weighing device 2 is increased, the resolution of constant flow control cannot be sufficiently improved. There is a problem that cannot be done.

When the first gate plate and the second gate plate begin to rotate, the bottom opening of the hopper is first opened only at the position of the notch formed at the tip of the first and second gate plates. . When the shape of the notch narrows toward the rear end of the first and second gate plates, as the rotation of the first and second gate plates progresses, the notch becomes narrower. The dispensing port formed by this gradually becomes larger.

ことができる。With this configuration, when the first and second gate plates 13a and 13b are positioned as shown in FIG.
The notch 20a of the first gate plate 13a is closed by the second gate plate 13b, and the bottom opening 5 of the hopper 1
The lower end opening 12 of the extension pipe 11 following this is closed, and the dispensing of the raw material is stopped. When the cylinder device 9 is operated, the support shaft 15a rotates and the first gate plate 13a rotates toward the position shown in FIG. 1st
As the gate plate 13a rotates, this rotation is transmitted to the support shaft 15b via the gears 17a and 17b, and the second gate plate 13b also rotates toward the position shown in FIG. First and second gate plates 13a, 1 shown in FIG.
At the rotating position 3b, the size of the outlet 2l formed by the notches 20a and 20b becomes larger than the lower end opening 12 of the extension tube 11, as shown in FIG. The opening 5 is fully open. Therefore, by adjusting the amount of protrusion and retraction of the rod 22 of the cylinder device 9, the first and second positions are adjusted between the position shown in FIG. 6 and the position shown in FIG.
By controlling the amount of rotation of the gate plates 13a and 13b, the size of the payout date 21 formed by the notches 20a and 20b can be changed almost continuously regardless of the width of the lower end opening l2 of the extension tube 11. The control unit 3
By operating the cylinder device 9 according to the above, it is possible to bring the discharge flow rate closer to the target flow rate value with higher resolution than before.

目標流量値に近ずけることができる。Effects of the Invention As described above, according to the present invention, the gate device in the loss-in weight constant flow dispensing device is configured such that the bottom opening of the hopper is closed by the first and second gate plates that rotate in opposite directions. The first and second gate plates are configured such that overlapping parts are provided at the tips of the first and second gate plates, and the first and second gate plates are electrically connected to each other.
, Since a notch is formed at the tip of the second gate plate, when the first and second gate plates are rotated, the notch formed at the tip of the first and second gate plates is cut out. The bottom opening of the hopper is opened first depending on the position, and the size of the dispensing port can be changed little by little regardless of the total width of the bottom opening of the hopper, and it is controlled based on the decrease in the weight value of the weighing device. By rotating the first and second gate plates through the part, the discharge flow rate can be brought closer to the target flow rate value with higher resolution than in the past.
