Description

本発明は、胴部よりも細径の口部を有する容器に、粉体を供給して充填する粉体供給装置に関する。 The present invention relates to a powder supply device that supplies and fills a container having a mouth portion having a diameter smaller than that of the body portion.

従来、ホッパー等の漏斗状の容器に投入された粉体を下方に吐出させて、下方に設置したビン等の容器に供給し充填する粉体供給装置がある。この種の粉体供給装置としては、粉体の供給量を安定させるために、漏斗状の容器内の粉体に対して気体を圧送し、気体とともに粉体を吐出する構成のものが知られている（例えば、特許文献１参照。）。 Conventionally, there is a powder supply device that discharges powder charged into a funnel-shaped container such as a hopper downward and supplies and fills the container such as a bottle installed below. As a powder supply device of this type, in order to stabilize the supply amount of powder, a configuration is known in which gas is pumped to the powder in a funnel-shaped container and the powder is discharged together with the gas. (See, for example, Patent Document 1).

特開２０１６－１４７２５３号公報Japanese Unexamined Patent Publication No. 2016-147253

しかし、特許文献１に記載の粉体供給装置を用いて、胴部よりも細径の口部を有する容器に対し、粉体（特に、軽く舞いやすい粉体）を供給し充填しようとすると、粉体とともに吐出された気体によって、容器の内部における気圧が上昇し、粉体が舞い上がってしまい、容器の口部から吹き出してしまうという問題があった。 However, when the powder supply device described in Patent Document 1 is used to supply and fill a container having a mouth portion having a diameter smaller than that of the body portion, powder (particularly, powder that is light and easy to fly) is to be supplied. There is a problem that the pressure inside the container rises due to the gas discharged together with the powder, the powder rises up, and the powder is blown out from the mouth of the container.

そのような吹き出しを防止する方法としては、粉体の供給速度（すなわち、粉体とともに吐出される気体の量）を抑制する方法が考えられる。しかし、そのように供給速度を抑制すると、作業効率の低下を招くことになってしまう。 As a method of preventing such blowout, a method of suppressing the supply speed of the powder (that is, the amount of gas discharged together with the powder) can be considered. However, if the supply speed is suppressed in this way, the work efficiency will be lowered.

本発明は以上の点に鑑みてなされたものであり、胴部よりも細径の口部を有する容器に対し、気体を含む粉体を効率良く供給し充填することができる粉体供給装置を提供することを目的とする。 The present invention has been made in view of the above points, and is a powder supply device capable of efficiently supplying and filling powder containing gas into a container having a mouth portion having a diameter smaller than that of the body portion.

本発明の実施形態に係る粉体供給装置の要部を断面として示した斜視図である。It is a perspective view which showed the main part of the powder supply apparatus which concerns on embodiment of this invention as a cross section.

以下、図面を参照して、本発明の実施形態に係る粉体供給装置について説明する。図１は、本発明の実施形態に係る粉体供給装置の要部を断面として示した斜視図である。図１における実線の矢印は、供給された粉体の移動経路を示し、破線の矢印は、粉体に含まれていた気体の移動経路を示す。 Hereinafter, the powder supply device according to the embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view showing a main part of the powder supply device according to the embodiment of the present invention as a cross section. The solid arrow in FIG. 1 indicates the movement path of the supplied powder, and the broken line arrow indicates the movement path of the gas contained in the powder.

図１に示すように、粉体供給装置１は、容器１０に圧送用の気体とともに粉体Ｐを供給し、充填するための装置である。粉体供給装置１は、容器１０に取り付けられている筒状部材２０と、筒状部材２０に挿入されているホッパー３０（漏斗状部材）と、粉体Ｐに気体を圧送する給気機構（不図示）とを備えている。 As shown in FIG. 1, the powder supply device 1 is a device for supplying and filling the powder P together with the gas for pumping into the container 10. The powder supply device 1 includes a tubular member 20 attached to the container 10, a hopper 30 (funnel-shaped member) inserted in the tubular member 20, and an air supply mechanism (air supply mechanism) for pumping gas to the powder P. (Not shown).

容器１０は、筒状の口部１１と、下方に向かって徐々に拡径する筒状であり、口部１１に連接されている肩部１２と、口部１１よりも太径の筒状であり、肩部１２に連接されている胴部１３と、胴部１３の下方に配置された底部１４とを有している。 The container 10 has a tubular mouth portion 11 and a tubular shape that gradually expands in diameter downward, and has a shoulder portion 12 connected to the mouth portion 11 and a tubular shape having a larger diameter than the mouth portion 11. It has a body portion 13 connected to the shoulder portion 12 and a bottom portion 14 arranged below the body portion 13.

筒状部材２０は、容器１０の口部１１の上端縁に載置される橋梁部２１と、橋梁部２１から下方に延設され、容器１０の口部１１の内側に嵌合される筒状の嵌合部２２とを有している。 The tubular member 20 has a bridge portion 21 placed on the upper end edge of the mouth portion 11 of the container 10, and a tubular member 20 extending downward from the bridge portion 21 and fitted inside the mouth portion 11 of the container 10. It has a fitting portion 22 of the above.

橋梁部２１は、環状の部材であり、その内径は、後述するホッパー３０の吐出部３２の外径と一致し、その外径は、容器１０の口部１１の外径よりも大きく形成されている。すなわち、筒状部材２０及びホッパー３０は、橋梁部２１を介して、容器１０の口部１１に係止されている。 The bridge portion 21 is an annular member, and its inner diameter coincides with the outer diameter of the discharge portion 32 of the hopper 30, which will be described later, and the outer diameter thereof is formed to be larger than the outer diameter of the mouth portion 11 of the container 10. There is. That is, the tubular member 20 and the hopper 30 are locked to the mouth portion 11 of the container 10 via the bridge portion 21.

橋梁部２１の形状は、上記のような径を有する環状に限定されるものではなく、筒状部材２０を容器１０の口部１１の上端縁に係止できる形状であれば、どのような形状であってもよい。例えば、ホッパー３０を別途保持する機構がある場合等には、筒状部材２０の嵌合部２２の上端部から延設された突起又はフランジをもうけ、それらを橋梁部としてもよい。 The shape of the bridge portion 21 is not limited to the annular shape having the diameter as described above, and any shape can be used as long as the tubular member 20 can be locked to the upper end edge of the mouth portion 11 of the container 10. May be. For example, when there is a mechanism for separately holding the hopper 30, a protrusion or a flange extending from the upper end of the fitting portion 22 of the tubular member 20 may be provided and these may be used as a bridge portion.

ホッパー３０は、逆円錐形状の粉体投入部３１と、粉体投入部３１の下方に設けられ、筒状部材２０の嵌合部２２に挿入される筒状の吐出部３２とを有している。
ここで、容器１０の口部１１、筒状部材２０の嵌合部２２及びホッパー３０の吐出部３２の軸線方向の長さ及び径の大きさについて説明する。 The hopper 30 has an inverted conical powder charging portion 31 and a tubular discharge portion 32 provided below the powder charging portion 31 and inserted into the fitting portion 22 of the tubular member 20. There is.
Here, the length and diameter of the mouth portion 11 of the container 10, the fitting portion 22 of the tubular member 20, and the discharge portion 32 of the hopper 30 in the axial direction will be described.

嵌合部２２は、容器１０に筒状部材２０を取り付けた際に、嵌合部２２の先端が容器１０の内部で口部１１よりも下方に突出するように形成されている。これにより、容器１０の内部の上方部分には、筒状部材２０の嵌合部２２の先端部によって、容器１０の内部で口部１１から下方に向かって突出する壁が形成されている。 The fitting portion 22 is formed so that the tip of the fitting portion 22 projects below the mouth portion 11 inside the container 10 when the tubular member 20 is attached to the container 10. As a result, in the upper portion of the inside of the container 10, a wall protruding downward from the mouth portion 11 inside the container 10 is formed by the tip end portion of the fitting portion 22 of the tubular member 20.

嵌合部２２の外径は口部１１の内径と略一致しており、容器１０に筒状部材２０を取り付けた際に、嵌合部２２は、口部１１の内側に嵌合する。
ホッパー３０の吐出部３２は、吐出部３２を嵌合部２２に挿入した際に、吐出部３２の先端が、嵌合部２２から下方に突出するように形成されている。 The outer diameter of the fitting portion 22 substantially coincides with the inner diameter of the mouth portion 11, and when the tubular member 20 is attached to the container 10, the fitting portion 22 fits inside the mouth portion 11.
The discharge portion 32 of the hopper 30 is formed so that the tip of the discharge portion 32 projects downward from the fitting portion 22 when the discharge portion 32 is inserted into the fitting portion 22.

吐出部３２の外径は嵌合部２２の内径よりも小径であり、嵌合部２２に吐出部３２を挿入した際には、吐出部３２と嵌合部２２との間に、所定の間隙が形成される。間隙は、粉粒体に応じて任意に設定することができる。例えば、間隙は０．５ｍｍ以上とすることができる。 The outer diameter of the discharge portion 32 is smaller than the inner diameter of the fitting portion 22, and when the discharge portion 32 is inserted into the fitting portion 22, a predetermined gap is provided between the discharge portion 32 and the fitting portion 22. Is formed. The gap can be arbitrarily set according to the powder or granular material. For example, the gap can be 0.5 mm or more.

上記のように、粉体供給装置１では、ホッパー３０の吐出部３２を筒状部材２０の嵌合部２２に挿入した際に、吐出部３２の先端が嵌合部２２から下方に突出するように（すなわち、吐出部３２の吐出口が容器１０の底部１４に近い位置となるように）構成されている。 As described above, in the powder supply device 1, when the discharge portion 32 of the hopper 30 is inserted into the fitting portion 22 of the tubular member 20, the tip of the discharge portion 32 projects downward from the fitting portion 22. (That is, the discharge port of the discharge unit 32 is located close to the bottom portion 14 of the container 10).

そのため、吐出部３２から吐出された粉体Ｐ及びその粉体に含まれる気体は、容器１０の底部１４に落下した後、径方向に広がるように移動し、さらにその後、容器１０の胴部１３に沿うようにして上方に向かって移動する（図１における実線で示した矢印、及び、破線で示した矢印参照。）。 Therefore, the powder P discharged from the discharge unit 32 and the gas contained in the powder fall to the bottom 14 of the container 10 and then move so as to spread in the radial direction, and then the body 13 of the container 10 is used. It moves upward along the line (see the arrow shown by the solid line and the arrow shown by the broken line in FIG. 1).

ここで、容器１０の内部の上方部分には、筒状部材２０の嵌合部２２の先端部によって、容器１０の内部で口部１１から下方に向かって突出する壁が形成されている。 Here, in the upper portion of the inside of the container 10, a wall protruding downward from the mouth portion 11 inside the container 10 is formed by the tip end portion of the fitting portion 22 of the tubular member 20.

この壁によって、胴部１３の内周面に沿って上方に移動していた粉体Ｐの移動は規制され、壁にぶつかった粉体Ｐは下方に落下することになる（図１における実線で示した矢印参照。）。 This wall restricts the movement of the powder P that has moved upward along the inner peripheral surface of the body portion 13, and the powder P that hits the wall falls downward (in the solid line in FIG. 1). See the arrow shown.).

一方、粉体Ｐに含まれていた気体の移動は、この壁によって一時的に胴部１３の上方（具体的には、壁と肩部１２の内周面との間）に滞留するが、順次ホッパー３０の吐出部３２と筒状部材２０の嵌合部２２との間の間隙から排出されていく（図１における破線で示した矢印参照。）。 On the other hand, the movement of the gas contained in the powder P temporarily stays above the body portion 13 (specifically, between the wall and the inner peripheral surface of the shoulder portion 12) due to this wall. The gas is sequentially discharged from the gap between the discharge portion 32 of the hopper 30 and the fitting portion 22 of the tubular member 20 (see the arrow shown by the broken line in FIG. 1).

また、筒状部材２０の橋梁部２１は、粉体を通過させずに気体のみを通過させる目の大きさの環状の網（金属、プラスチック、繊維など）によって構成することができる。橋梁部２１を網によって構成することで、排出される気体に粉体Ｐが残留していたとしても、その粉体Ｐは、橋梁部２１によってホッパー３０の吐出部３２と筒状部材２０の嵌合部２２との間の間隙から拡散することを低減もしくは防止することができる。 Further, the bridge portion 21 of the tubular member 20 can be formed of an annular net (metal, plastic, fiber, etc.) having a mesh size that allows only gas to pass through without passing powder. By forming the bridge portion 21 with a net, even if the powder P remains in the discharged gas, the powder P is fitted to the discharge portion 32 of the hopper 30 and the tubular member 20 by the bridge portion 21. It is possible to reduce or prevent diffusion from the gap between the joint portion 22 and the joint portion 22.

したがって、本発明の粉体供給装置１によれば、粉体Ｐを容器の内部に留まらせるとともに、粉体Ｐに含まれていた気体のみを順次排出できるので、粉体Ｐの供給速度を抑制することなく、胴部１３よりも細径の口部１１を有する容器１０に対し、気体を含む粉体Ｐを効率良く供給し充填することができる。 Therefore, according to the powder supply device 1 of the present invention, the powder P can be retained inside the container and only the gas contained in the powder P can be sequentially discharged, so that the supply speed of the powder P can be suppressed. The powder P containing gas can be efficiently supplied and filled in the container 10 having the mouth portion 11 having a diameter smaller than that of the body portion 13.
