背景技術 Background art
粉粒体の搬送、 バッチ計量、 混合、 貯蔵などに用いる手段と して、 粉粒体の投入口およ び排出口を備えた容器であるコンテナが広く利用されている。 粉粒体としては、 粉あるい は粒状の、 医薬品、 食糧品、 プラスチック、 建材など、 多種多様である。 Containers, which are containers equipped with a powder inlet and outlet, are widely used as a means for transporting powder, batch weighing, mixing, and storage. There are a wide variety of powdered and granular materials such as pharmaceuticals, foodstuffs, plastics, and building materials.
典型的なコンテナは、 筒状たて型の上部に投入口を設けた本体部と、 投入口の蓋である 上蓋と、 下端部に排出口を設けた漏斗状の底部と、 排出口に開閉自在に設けた弁体を有す る排出装置とを備えている。 弁体の典型例は、 排出口に内接する板状の弁体を、 軸線を中 心に回転させ排出口の開きを加減する周知のバタフライ弁を備えている。 A typical container consists of a main body with an inlet at the top of a cylindrical vertical mold, an upper lid that is a lid for the inlet, a funnel-shaped bottom with an outlet at the lower end, and an open / close at the outlet And a discharge device having a freely provided valve body.

弁体の開閉による粉粒体の排出を円滑にし、 また弁体部分に粉粒体が付着 ·残留するの を防止する改良された排出装置と して、 弁体を円錐状に形成し、 その底面をコンテナの内 側において排出口に接離自在に当接させ、 弁体に連結する軸部材を、 コンテナ内を通し上 蓋から突出させ、 この軸部材をコンテナの外から操作して排出口を開閉する排出装置が開 発され、 実用に供されている (例えば、 特許文献 1参照) 。 The valve body is formed in a conical shape as an improved discharge device that facilitates the discharge of powder particles by opening and closing the valve body and prevents the powder particles from adhering to and remaining on the valve body part.

発明の開示 Disclosure of the invention
しかしながら、 上述したとおりの形態の従来のコンテナ排出装置には、 次のとおりの改 良の望まれている問題がある。 However, the conventional container discharging apparatus of the form as described above has the following problems that are desired to be improved.
すなわち、 周知のバタフライ弁は、 板状の弁体と弁体を支持する弁軸とからなる簡単な 構造であり、 弁軸を回転させ弁体による排出口の開きを加減することでコンテナに収容さ れた粉粒体の排出速度である供給速度そしで供給量を制御することができる。 In other words, the well-known butterfly valve has a simple structure consisting of a plate-shaped valve body and a valve shaft that supports the valve body, and is accommodated in a container by rotating the valve shaft and adjusting the opening of the discharge port by the valve body. The supply rate can be controlled by the supply rate which is the discharge rate of the granular material.
しかしながら一般的に粉粒体は流動性が悪く、 排出速度を遅くするために板状の弁体に より排出口の開度を小さくすると、 粉粒体はほとんど流出しなくなる。 さらに弁体は、 排 出口の部分において弁軸を中心に回転する構造であるので、 弁体の部分の粉粒体のみが排 出され、 コンテナ内の粉粒体は排出されないで固着した状態になりやすい。 特に流動性の 悪い粉粒体は弁体を開けただけでは流出しない。 However, in general, the granular material has poor fluidity, and if the opening degree of the discharge port is reduced by a plate-shaped valve body in order to slow down the discharging speed, the granular material hardly flows out. Furthermore, since the valve body has a structure that rotates around the valve shaft at the outlet and outlet part, only the granular material in the part of the valve body is discharged, and the granular substance in the container is fixed without being discharged. Prone. In particular, powder with poor fluidity will not flow out just by opening the valve.
一方、 円錐状の弁体を備えた改良された排出装置は、 弁体およびそれに連結した軸部材 が排出口の開閉に応じコンテナ内を上下に移動するので、 コンテナ内の粉粒体は攪拌され、 崩され、 固着しにく く、 排出口からの粉粒体の排出速度を制御しやすい。 On the other hand, in the improved discharge device provided with the conical valve body, the valve body and the shaft member connected thereto move up and down in the container according to the opening and closing of the discharge port, so that the powder particles in the container are agitated. It is easy to control the discharge speed of the granular material from the discharge port.
しかしながら、 円錐状の弁体を備えた排出装置は、 個々のコンテナそれぞれに専用に設 置する必要があり汎用性がないので、 経済面からは比較的限定された用途に用いられる。 またこの排出装置は、 コンテナ内に円錐状の弁体、 および軸部材などが設置され構造が比 較的複雑であるので、 コンテナ内に付着した粉粒体の清掃、 異種の粉粒体を扱う場合に必 要なコンテナ内の清掃などが面倒である。 However, the discharge device provided with the conical valve body needs to be installed in each individual container and is not versatile. Therefore, it is used for comparatively limited applications from the economic aspect. In addition, since the structure of the discharge device is relatively complicated with a conical valve body and shaft member installed in the container, cleaning of the granular material adhering to the container and handling different types of granular material are handled. It is troublesome to clean the inside of the container that is necessary.

上述したとおりのコンテナ排出装置 2の作用について説明する。 The operation of the container discharge device 2 as described above will be described.
コンテナ排出装置 2は、 コンテナ 4の排出口 5の開閉に構造が比較的簡単なバタフライ 弁装置 1 0を用い、 その弁板 6を振動させる弁加振手段 1 2を備え、 さらに弁板 6および 排出口 5に向けて空気を噴射する空気噴射手段 1 4を備えている。 したがって、 弁板 6を 振動させまた弁板 6およびその周辺に噴射空気を吹き付けるので、 排出口 5の小さな開度 から大きな開度まで、 粉粒体の弁板 6への付着およびコンテナ 4内における固着を防止す ることができ、 比較的簡単な構造で、 粉粒体を定量的 ·連続的に、 そして円滑に取り出す ことができる。 The container discharge device 2 includes a butterfly valve device 10 having a relatively simple structure for opening and closing the discharge port 5 of the container 4, and is provided with valve vibration means 12 that vibrates the valve plate 6. Air injection means 14 for injecting air toward the discharge port 5 is provided. Therefore, the valve plate 6 is vibrated and the sprayed air is blown to the valve plate 6 and its surroundings, so that the granular material adheres to the valve plate 6 from the small opening to the large opening of the discharge port 5 and in the container 4. It is possible to prevent sticking, and with a relatively simple structure, powder particles can be taken out quantitatively, continuously and smoothly.
なお、 空気噴射手段 1 4により空気を噴射するときに、 シュート 1 6につながる粉粒体 供給機などを閉止状態にすると、 噴射した空気によってコンテナ 4内部の粉粒体をより効 果的に流動化させることができる。 When air is sprayed by the air injection means 14, if the powder supply unit connected to the chute 16 is closed, the powder inside the container 4 flows more effectively by the injected air. It can be made.
弁加振手段と してのバイブレータ 1 2は弁軸 8にのみに取り付けられるので、 設置が容 易であり、 また排出装置 2をコンパク トにまとめることができる。 The vibrator 12 as a valve vibration means is attached only to the valve shaft 8, so that the installation is easy and the discharge device 2 can be combined into a compact.
空気噴射手段 1 4は、 円筒部 1 4 aの内周面に開口した複数個の空気噴射口である、 バ タフライ弁装置 1 0の弁板 6に向けて空気を噴射する弁方向噴射口 1 4 b と、 内周面の周 方向に向けられた周方向噴射口 1 4 cを備えているので、 粉粒体の弁板 6への付着、 コン テナ 4内および弁板 6周辺での固着を防止することができる。 The air injection means 14 is a plurality of air injection openings opened on the inner peripheral surface of the cylindrical portion 14 a, and a valve direction injection opening 1 that injects air toward the valve plate 6 of the butterfly valve device 10. 4 b and circumferential injection port 1 4 c oriented in the circumferential direction of the inner peripheral surface, so that powder particles adhere to the valve plate 6 and adhere to the container 4 and around the valve plate 6 Can be prevented.
そして、 弁方向噴射口 1 4 bから弁板 6に向けて噴射される空気は、 弁軸 8の軸線 Xの 延びる方向に向けられているので、 空気は弁板 6 と排出口 5の開口部分を通してコンテナ 4内に効果的に噴射される。 And since the air injected toward the valve plate 6 from the valve direction injection port 14 b is directed in the direction in which the axis X of the valve shaft 8 extends, the air is the opening portion of the valve plate 6 and the discharge port 5. Is effectively injected into the container 4 through.
さらに、 空気噴射口 1 4 b、 1 4 cそれぞれに、 多孔質の焼結金属からなる網部材 1 4 dを備えたので、 粉粒体が噴射口に流れこむのを効果的に止めることができる。 Furthermore, since each of the air injection ports 14 b and 14 c has a mesh member 14 d made of porous sintered metal, it is possible to effectively stop the powder from flowing into the injection ports. it can.
コンテナ排出装置 2は、 コンテナ 4の排出口 5にバタフライ弁装置 1 0が、 バタフライ 弁装置 1 0に空気噴射手段 1 4が、 それぞれ着脱を自在に、 例えばフェル一ル継手 1 8よ つて取り外しを自在に取り付けられているので、 それぞれを外して容易に清掃することが できる。
この着脱自在なコンテナ排出装置 2は、 排出口 5が同一形状に形成された異なったコン テナに容易に適宜に着脱することができるので、 コンテナ内に専用に設けた円錐状の弁体 を備えるコンテナ排出装置に比べて、 汎用的に用いることができ経済的である。
The container discharge device 2 has a butterfly valve device 10 at the discharge port 5 of the container 4, and an air injection means 14 at the butterfly valve device 10 0, which can be freely attached and detached, for example, with a ferrule joint 18. Since they are attached freely, they can be removed and cleaned easily. This detachable container discharge device 2 includes a conical valve body provided exclusively in the container because the discharge port 5 can be easily attached to and detached from different containers having the same shape. Compared to container discharge devices, it can be used for general purposes and is economical.
