給における閉塞の問題も考慮する必要があった。However, the above-mentioned conventional feeding devices have the disadvantage that the discharge adjustment mechanism itself is structurally complex and expensive, and most of these discharge adjustment mechanisms are installed outside the hopper outlet. Therefore, depending on the form of transporting the powder or granular material at the hopper outlet (for example, pneumatic transport), there have been problems such as the inability to easily incorporate and install the hopper into an existing hopper or the like. In addition, it was necessary to consider the problem of blockages in the supply of powder or granules with poor fluidity.

なく、ホッパーの外部に設置してもよい。FIG. 1 shows an embodiment of the continuous quantitative feeding device of the present invention. 1 is a granular material, 2 is a hopper that stores the granular material 1, 3 is a telescoping valve body that quantitatively discharges the granular material 1 from the outlet 4 of the hopper 2, and 5 is a telescopic valve body that allows the valve body 3 to expand and contract up and down. The vibration drive unit for this purpose is shown. Telescopic valve body 3 in this embodiment
is made of a coil spring-like structure as shown in the figure, and is attached to the inside of the hopper outlet 4 with the lower end of the coil spring fixed. The vibration driving unit 5 has an electromagnet 6 as a driving source, and has a mechanism that forcibly expands and contracts the valve body 5 in the vertical direction via a metal plate 7 fixed to the upper part of the valve body 3. . The electromagnet 6 is fixed in a support tube 8 introduced and installed inside the pumper 2, and is driven by an electric signal from a power supply/control device 9. Further, the electromagnet 6 does not necessarily have to be installed inside the hopper, but may be installed outside the hopper.

自在であり、しかも強制的な上下伸縮により少なくとも
局面（側部）一部に粉粒体が通過可能な間隙が瞬時的に

い範囲内にある開口サイズであることが必要である。The telescopic valve body 3 used in the device of the present invention is elastic enough to restore its entire shape in the vertical direction (in the direction of arrow A in the figure), and can be expanded and contracted at least on the sides (the sides) by forced vertical expansion and contraction. ) Any hollow structure may be used as long as it is a hollow structure in which a gap is instantaneously formed in a part through which the powder or granular material can pass.From this point of view, a valve body made of a coil spring body as shown in this embodiment is most suitable. Not limited. Here, the gap through which the powder or granule can pass does not simply mean a gap with an opening area larger than the particle size of the powder or granule, but also the gap through which the powder or granule can pass (leak) when the valve body 3 is expanded. This is a general term for the voids within the range. Therefore, the valve body 3 is not limited to one that has no gaps (voids) at all in a stationary state, but may also have a gap that is larger than the particle size of the powder or granule, but in that case, the gap in the stationary state is It is necessary that the opening size is within a range that does not allow the powder to naturally flow out when the body is not vibrated.

Examples include a structure made of a spring (the gap formed by vertical expansion and contraction in a bamboo shoot spring valve body has a spiral shape when viewed from above). Further, the overall shape of the valve body 3 (including the shape of the inner cavity) is not limited to a circular M (column) shape, but may be a conical shape, an inverted conical shape, etc., and furthermore, the horizontal cross-sectional shape of the valve body 3 The shape is not limited to a circle, but may be a polygon such as a quadrangle or a triangle, or an irregular shape.

かも良好に分散されている。When the t-magnet 6 of the vibration drive unit 5 is not operating, the valve body 3 of the powder body 1 is not expanded (even if there is a gap in the free length of the coil spring, the line of the coil spring (forming a bridge between them) remains deposited around the valve body and does not flow into the cavity 10 of the valve body. When the electromagnet 6 is activated, the valve body 3 begins to expand and contract in the vertical direction, causing the powder 1 around the valve body to
is agitated and fluidized by the vertical slight movement of the valve body, and at the same time receives pressure from other granules (back pressure) from the back side, and flows through the gap 11 formed when the valve body expands, as illustrated by arrow B in the figure. It flows into the body cavity 10 at any time, and then the hopper outlet 4
is discharged from. At this time, since the valve body 3 continuously expands and contracts little by little, the gap 11 is also formed in a similar period, and as a result, the powder flowing out through the valve body 5 is always quantitative and well dispersed.

うことができる。The flow rate of the powder discharged from the hopper via the valve body 3 depends on the conditions of the valve body 3 itself (for example, the size of the gap 11, the total length of the valve body, the overall shape and circumference size of the valve body, etc.), and the vibration excitation. It can be adjusted by variously changing the conditions of the drive unit 6 itself (for example, amplitude voltage, vibration frequency, etc.). According to the device of the present invention, by appropriately adjusting these conditions, even if the particle size, fluidity, material, etc. of the powder or granules are different, it is possible to provide the same good quantitative supply to each powder or granule. It can be carried out.
