Description

【０００１】
【発明の属する技術分野】
本発明は、医薬品，農薬，食品などの錠剤，ソフトカプセル，ペレット，顆粒などを製造する際に用いられる粉粒体処理装置に関し、詳しくは、回転ドラム内で粉粒体原料の造粒，コーティング，乾燥などの処理を行なった粉粒体製品を回転ドラムから自動的に排出する機構を備えた粉粒体処理装置に関する。
【０００２】
【従来の技術】
例えば、錠剤，顆粒などの粉粒体粒子にフィルムコーティングや糖衣コーティングなどを施すために、回転ドラムを備えた粉粒体処理装置が使用されている。横型回転ドラムを備えた粉粒体処理装置の基本構造例として、図１１および図１２に示すものが知られている。
【０００３】
図１１は横型回転ドラム２を有する粉粒体処理装置の側面図で、ケーシング１の中に回転ドラム２がその水平な軸線を中心に回転可能に配置される。回転ドラム２は円筒状または多角筒状の胴体部３と、胴体部３の軸方向前後両端側に連なる傾斜状の前壁部４および後壁部５と、前壁部４の先端中心に設けられたフロントリング６によって形成される開口部７を有する。胴体部３は通気用多孔部に構成され、この通気用多孔部の外面側にエアーチャンネル８が設けられる。各エアーチャンネル８はそれぞれ後壁部５の外面に沿って延び、給排気装置のディストリビュータ９に連通する。
【０００４】
ディストリビュータ９は給気ダクトと排気ダクトに接続されており、任意の空気チャネル８が所定の位置に回転移動してくると、この空気チャネル８を介して乾燥空気（温風）が回転ドラム２内に供給され、同時に、別の空気チャネル８を介して回転ドラム２内の空気が排出される。このようなディストリビュータ９の機能で、回転ドラム２内に上向きまたは下向き等の空気流が生じる。
【０００５】
回転ドラム２の前壁部４は、胴体部３から前方に傾斜状に延在し、その先端部にフロントリング６等のリング部材で構成される開口部７が設けられる。回転ドラム２内への粉粒体原料の投入、および回転ドラム２内からの粉粒体製品の排出は、開口部７を介して行なう。
【０００６】
図１２は、回転ドラム２内で粉粒体原料の造粒やコーティング処理を行なう時の状態を示すもので、開口部側から見た軸線方向に直交する縦断面を示している。回転ドラム２を駆動モータ１１によって矢印方向に回転させ、同時に給排気を行って、回転ドラム２内に粉粒体１２の転動床を形成し、その粉粒体１２の転動床に向けて、スプレーノズル１３からバインダ液やコーティング液等のスプレー液１４をスプレーする。これにより、回転ドラム２内の粉粒体粒子が湿潤を受けて凝集し、あるいは、粉粒体粒子の表面にスプレー液中の基材成分が付着して被複層が形成される。
【０００７】
上記のようにして造粒やコーティング処理を行った後、処理が完了した粉粒体製品を回転ドラム２内から排出するが、そのための機構として、従来、回転ドラムの前壁部の内面に中空状のブレードを突設して、排出時に回転ドラムを粉粒体処理時とは逆方向に回転させることにより、回転ドラム内の粉粒体製品を前記ブレードによって開口部まで案内して、開口部から自動排出する機構が知られている。（例えば、特許文献１参照。）。
【０００８】
あるいは、回転ドラムの前壁部の内面に板状部材により構成される中空状の製品排出手段を突設し、または、回転ドラムの胴体部の内面から前壁部の内面および開口部の近傍にかけて板状排出部材を突設し、排出時に回転ドラムを粉粒体処理時とは逆方向に回転させることにより、回転ドラム内の粉粒体製品を前記製品排出手段、板状排出部材によって開口部まで案内して、開口部から自動排出する機構が知られている（例えば、特許文献２参照。）。

【発明が解決しようとする課題】
上述した粉粒体処理装置によれば、回転ドラム２の正回転で粉粒体を処理し、回転ドラム２の逆回転で粉粒体製品を排出することができるが、排出部材が回転ドラムの内面に突起状に設けられているため、以下のような問題が生じる。
【００１１】
（１）粉粒体原料の処理時（回転ドラムの正回転時）、回転ドラム内の粉粒体１２が排出部材によって持ち上げられ、転動床の上層部分が波打つ現象が起こる。そのため、スプレー液１４の均一なスプレーが難しくなり、粉粒体製品の品質面に影響する場合がある。
【００１２】
（２）粉粒体製品の排出時（回転ドラムの逆回転時）、回転ドラム内の粉粒体製品の残量に応じて、排出部材によるすくい上げ量が変化するので、単位時間当たりの排出量の調整が困難である。
【００１３】
（３）回転ドラムの内部に排出部材による突起物があると、粉粒体原料の投入時、サンプリング製品の目視確認時、スプレーノズルの点検時の引出時、清掃時などにおける作業が不便である。
【００１４】
（４）粉粒体原料の処理時（回転ドラムの正回転時）と、粉粒体製品の排出時（回転ドラムの逆回転時）とで、回転ドラムを正回転または逆回転に切り換えなければならないため、正逆回転可能な駆動源が必要不可欠である。
【００１５】
そこで、本発明の目的は、粉粒体製品の確実な自動排出を可能にすると共に、粉粒体の処理時に、排出部材が回転ドラムの内面に突起状に設けられていることに起因する、上述した従来装置の問題点を解決することにある。
【００１６】
【課題を解決するための手段】
上記課題を解決するため、本発明は、軸線回りに回転可能な回転ドラムを備え、前記回転ドラムは、筒状でかつその少なくとも一部に通気用多孔部を有する胴体部と、この胴体部に連なる傾斜状の前壁部および後壁部と、前記前壁部の端部に設けられた開口部とを有する粉粒体処理装置において、前記回転ドラム内の粉粒体製品の排出時に、回転ドラムに着脱自在に取付けられ、その側縁部が前記前壁部に配置されると共に、その胴体部側の端縁部が胴体部に配置される製品排出プレート部材と、前記回転ドラム内の粉粒体製品の排出時に、前記回転ドラムに着脱自在に取付けられ、その側縁部が胴体部に配置され、前記製品排出プレート部材に向かって粉粒体製品の流動を促進させる製品排出促進スコープ部材とを設けたことを特徴とする構成を提供する。
【００１７】
上記の「側縁部が前記前壁部に配置される」、「その胴体部側の端縁部が胴体部に配置される」あるいは「その側縁部が胴体部に配置され」なる用語は、それぞれの側縁部や端縁部が、前壁部や胴体部に接触させて配置される場合や、処理する粉粒体原料の粒径寸法よりも小さい隙間を介して配置される場合を含むものである。
【００１８】
この構成によれば、従来の回転ドラム内に排出部材を固定した粉粒体処理装置に比較して、以下のような各種の優れた作用が得られる。
【００１９】
（１）回転ドラム内の粉粒体製品の排出時に、回転ドラムに、製品排出プレート部材を着脱自在に取付けると共に、前記製品排出プレート部材に向かって粉粒体製品の流動を促進させる製品排出促進スコープ部材を着脱自在に取付けるので、回転ドラムを所定方向に回転させることによって、回転ドラム内の粉粒体製品を、上述した製品排出促進スコープ部材によって、製品排出プレート部材の方に向かって流動させることができると共に、粉粒体製品を製品排出プレート部材によって、回転ドラムのマウスリングへと流動させることができる。したがって、粉粒体製品を回転ドラム内から自動的に、かつ確実に排出することができる。
【００２０】
（２）粉粒体原料の処理時には、回転ドラム内に製品排出プレート部材および製品排出促進スコープ部材が存在しないので、回転ドラム内の粉粒体原料が製品排出プレート部材および製品排出促進スコープ部材によって持ち上げられることに起因する転動床の上層部分が波打つ現象が起きない。そのため、スプレー液の均一なスプレーが可能になり、高品質の製品が短時間で得られる。
【００２１】
（３）粉粒体製品の排出時、回転ドラム内の粉粒体製品の残量による、製品排出プレート部材および製品排出促進スコープ部材によるすくい上げ量の変化が小さいので、単位時間当たりの排出量の調整が容易である。
【００２２】
（４）粉粒体製品の排出時以外の常時には、回転ドラム内に製品排出プレート部材および製品排出促進スコープ部材による突起物がないので、開口部から回転ドラム内に粉粒体原料を投入時、サンプリング製品の目視確認時、スプレーノズルの点検時の引出時および清掃時などの作業が容易に行なえる。
【００２３】
（５）粉粒体原料の処理時と粉粒体製品の排出時とで、回転ドラムを同一方向に回転させるため、一方向のみに回転可能な駆動源を使用することができ、正逆回転可能な駆動源は必ずしも必要ではない。ただし、既存の設備を改造する場合やその他の理由により、正逆回転可能な駆動源を用いることを排除するものではない。
【００２４】
本発明ではまた、軸線回りに回転可能な回転ドラムを備え、前記回転ドラムは、筒状でかつその少なくとも一部に通気用多孔部を有する胴体部と、この胴体部に連なる傾斜状の前壁部および後壁部と、前記前壁部の端部に設けられた開口部とを有し、前記胴体部に所定角度ですくい上げ板を取付けた粉粒体処理装置において、前記回転ドラム内の粉粒体製品の排出時に、回転ドラムに着脱自在に取付けられ、その側縁部が前記前壁部に配置されると共に、その胴体部側の端縁部がすくい上げ板に配置される製品排出プレート部材と、前記回転ドラム内の粉粒体製品の排出時に、前記回転ドラムに着脱自在に取付けられ、その側縁部がすくい上げ板に配置され、前記製品排出プレート部材に向かって粉粒体製品の流動を促進させる製品排出促進スコープ部材とを設けた構成としてもよい。
【００２５】
上記構成によれば、上述と同様の作用が得られるのみならず、回転ドラムの胴体部にすくい上げ板を取付けているので、粉粒体の処理時に、回転ドラム内の粉粒体が、すくい上げ板の前縁部ですくい上げられ、後縁部から落下するので、粉粒体の撹拌作用が向上して、高品質の粉粒体製品を短時間で製造できる。また、粉粒体製品の排出時には、回転ドラムに製品排出プレート部材および製品排出促進スコープ部材を着脱自在に取付けることによって、回転ドラムの回転動作により、すくい上げ板上の粉粒体製品が、製品排出促進スコープ部材で製品排出プレート部材側に流動させられ、流動させられた粉粒体製品が製品排出促進スコープ部材で、開口部に向かって搬送されていく。したがって、回転ドラム内から粉粒体製品を自動的に、かつ確実に排出することができる。
【００２６】
以上の構成において、前記すくい上げ板が、胴体部との間に回転ドラムの回転方向の前縁部での通気用開口部を有し、さらに前記回転ドラム内の粉粒体製品の排出時に、前記回転ドラムに着脱自在に取付けられ、前記通気用開口部を閉止する第２排出促進スコープ部材を有する構成としてもよい。
【００２７】
このような構成によれば、すくい上げ板が回転ドラムの回転方向の前縁部での通気用開口部を有するので、粉粒体の処理時に、前記通気用開口部を通ってすくい上げ板と胴体部との間の通気用通路を空気が流れて、後縁部での通気用開口部から回転ドラム内に放出されるので、すくい上げ板の後縁部から落下する粉粒体の撹拌効果を向上することができ、均質な粉粒体の処理が短時間で行なえる。また、粉粒体製品の排出時には、回転ドラムに第２製品排出促進スコープ部材を着脱自在に取付け、前縁部での通気用開口部を第２製品排出促進スコープ部材で閉止することによって、粉粒体製品がこの前縁部での通気用開口部個所に滞留したり、前縁部での通気用開口部を通ってすくい上げ板の下方に浸入したりすることが防止されるため、回転ドラム内の製品を最後の１個まで確実に排出することが可能になる。
【００２８】
以上の構成において、前記製品排出促進スコープ部材と、第２製品排出促進スコープ部材と、製品排出プレート部材とを、回転ドラムの回転方向の前方から後方にかけて順次に配置した構成としてもよい。
【００２９】
上記の構成によれば、すくい上げ板上の粉粒体製品が、回転ドラムの所定方向への回転動作に伴って、製品排出促進スコープ部材によって製品排出プレート部材側に流動させられ、先行するすくい上げ板から後続のすくい上げ板に落下移動する際に、後続のすくい上げ板の前縁部での通気用開口部が第２製品排出促進スコープ部材によって閉止されているから、粉粒体製品が後続のすくい上げ板の前縁部での通気用開口部に滞留したり、その通気用開口部に浸入したりすることが防止され、さらに後続のすくい上げ板に移動した粉粒体製品が製品排出プレート部材によって開口部に向かって搬送されていくので、粉粒体製品を回転ドラム内から自動的に、かつ確実に排出することができる。
【００３０】
【発明の実施の形態】
以下、本発明の実施形態に係る粉粒体処理装置について、図面を参照して説明する。
【００３１】
図１は、第１実施形態に係る粉粒体処理装置の回転ドラム２内で粉粒体原料の造粒やコーティング処理を行なう時の一部を断面で示す概略側面図で、図２は開口部側から見た軸線方向に直交する縦断面を示している。図１および図２において、図１１および図１２と同一の部分には同一参照符号を付したので、その説明を省略する。図１１および図１２との相違点は、本発明における回転ドラムは、基本的には一方向のみに回転可能であればよいので、所定方向にのみ回転可能な回転駆動源１５を設けている。また、回転ドラム２の胴体部３の各通気用多孔部に対して、回転ドラム２の回転方向の前方側が低く、後方側が高くなる傾斜状にすくい上げ板２０を取付けていることである。
【００３２】
回転ドラム２に取付けられたすくい上げ板２０は、すべて同一の台形状である。台形状にする理由は、回転ドラム２が、傾斜状の前壁部４および後壁部５を有しており、前述のように、すくい上げ板２０を回転ドラム２の回転方向の前方側が低く、後方側が高くなる傾斜状に取付けた場合、すくい上げ板２０の前縁部２０ａ側の側縁部は、前壁部４および後壁部５の胴体部３に近い位置に接するのに対して、すくい上げ板２０の後縁部２０ｂ側の側縁部は、前壁部４および後壁部５の胴体部３から離隔した位置に接するためである。
【００３３】
すくい上げ板２０は、図３に示すように、回転ドラム２の回転方向の前縁部２０ａの胴体部３からの高さ寸法ｈ１（図示省略）が、粉粒体の寸法ｄよりも大きい（ｈ１＞ｄ）前縁部での通気用開口部２１を設けて取付けられ、後縁部２０ｂの胴体部３からの高さ寸法ｈ２（図示省略）が、前記前縁部での通気用開口部２１の高さ寸法ｈ１よりも大きい（ｈ２＞ｈ１）後縁部での通気用開口部２２を設けるように、図示しないボルト軸およびナットにより、前低・後高の所定角度で傾斜状に取付けられている。そして、すくい上げ板２０と胴体部３の通気用多孔部との間に、通気用多孔部から供給された乾燥空気などが通り抜ける通気用通路２３が形成されている。
【００３４】
前記すくい上げ板２０の前縁部２０ａが、図３に示すように、胴体部３との間に、前縁部での通気用開口部２１を形成するすくい上げ板２０の前方部には、多角形状の胴体部３と略平行の屈曲部２０ｃを有する。そして、必要に応じて、胴体部３における前縁部での通気用開口部２１の回転方向の少し前方位置に、粉粒体がすくい上げ板２０の上面に乗り易いように、粉粒体のガイド部材２４が設けられている。
【００３５】
したがって、上記のすくい上げ板２０を有する粉粒体処理装置において、ダイレクト吸気方式によって給排気を行なう場合は、回転ドラム２の上部の空気チャンネル８を通って胴体部３の通気用多孔部から通気用通路２３およびすくい上げ板２０の後縁部２０ｂでの通気用開口部２２を通って胴体部３内に供給された乾燥空気が、回転ドラム２の下部のすくい上げ板２０の後縁部２０ｂから落下する粉粒体粒子１２，１２間を通り抜けて、すくい上げ板２０の後縁部２０ｂの通気用開口２２から通気用通路２３に入り、胴体部３の通気用多孔部から空気チャンネル８を通って回転ドラム２の外部に抜け出るので、すくい上げ板２０を有しない粉粒体処理装置に比較して、粉粒体粒子１２の転延効果が向上し、均一な処理を短時間で行なうことができる。
【００３６】
また、すくい上げ板２０の前縁部２０ａに前縁部での通気用開口部２１が形成されているので、この前縁部での通気用開口部２１付近の粉粒体粒子１２の転動床を通り抜けた乾燥空気が通気用通路２３に進入して、通気用多孔部から空気チャンネル８を通って排気ダクトに放出される結果、すくい上げ板２０の前縁部２０ａが胴体部３に接している場合に比較して、粉粒体粒子１２の乾燥効果がさらに向上する。
【００３７】
上記の粉粒体処理装置においては、図４に示すように、前記開口部７を形成するフロントリング６に、製品排出部３０が設けられている。この製品排出部３０は、フロントリング６の下方部に設けられた製品排出シュート３１と、この製品排出シュート３１に開閉自在に装着された蓋３２とで構成されている。製品排出シュート３１は、粉粒体原料の投入時や、粉粒体の処理時には、蓋３２によって閉止されており、粉粒体製品の排出時には蓋３２が取外される。
【００３８】
上記の粉粒体処理装置において、粉粒体製品の排出時には、回転ドラム２の前壁部４のマウスリングに、製品排出プレート部材４０が着脱自在に取付けられる。この製品排出プレート部材４０は、図５に示すように、マウスリングへの取付孔４１ａ，４１ｂを有する取付部４１と、この取付部４１からマウスリングに沿って円弧状に延びる円弧状部４２と、この円弧状部４２から中心部に向かってほぼ垂直状に立上り、かつ軸線方向に延びる基部４３と、基部４３から前壁部４に沿って胴体部３に向かって延びる製品搬送部４４と、この製品搬送部４４と隣接し、かつその製品搬送部４４側とは反対側の側縁部４５ａが前壁部４に接触し、かつ前壁部４に対して所定角度傾斜しているすくい上げ用の傾斜面部４５と、前記基部４３および製品搬送部４４の側縁部に沿って設けられ、かつ基部４３および製品搬送部４４に対して直立状または回転ドラム２の回転方向に向かって傾斜している粉粒体製品の落下防止用の縁部４６とを有している。
【００３９】
前記製品排出プレート部材４０は、回転ドラム２がすくい上げ板２０を有するか否かによって、その長さ寸法が設定される。すなわち、回転ドラム２の胴体部３にすくい上げ板２０を有しない場合は、製品排出プレート部材４０の製品搬送部４４，傾斜面部４５および縁部４６の胴体部３側の端部４４ｂ，４５ｂおよび４６ａは、胴体部３に接触または微小隙間で近接する長さに設定される。また、回転ドラム２の胴体部３にすくい上げ板２０が設けられている場合は、製品排出プレート部材４０の製品搬送部４４，傾斜面部４５および縁部４６の胴体部３側の端部４４ｂ，４５ｂおよび４６ａは、すくい上げ板２０に接触または微小隙間で近接する長さに設定される。図４は、すくい上げ板２０を設けている場合を示し、かつ前記端部４４ｂ，４５ｂは、すくい上げ板２０の上面に接触している。
【００４０】
前記製品搬送部４４は、基部４３から胴体部３側に向かって漸次その幅寸法が小さくなるように略三角形状に形成され、一方、前記傾斜面部４５は、基部４３側から胴体部３側に向かって漸次その幅寸法が大きくなるように略逆三角形状に形成されており、かつ前記製品搬送部４４は、前壁部４に対してほぼ垂直状に、また、前記傾斜面部４５は、前壁部４に対して適当な傾斜角度，例えば８５°〜４５°程度の傾斜状になるように、製品搬送部４４と傾斜面部４５との接合部４４５で、図４および図５の手前方向に凸状に屈曲されている。
【００４１】
図６は粉粒体製品の排出時において、回転ドラム２のマウスリングに着脱自在に取付けられている製品排出促進スコープ部材５０の斜視図である。この製品排出促進スコープ部材５０は、マウスリングへの取付孔５１ａ，５１ｂを有する取付部５１と、取付部５１からマウスリングに沿って円弧状に延びる円弧状部５２と、この円弧状部５２から前壁部４に沿って延びる支持部材取付部５３と、この支持部材取付部５３に取付けられた複数の棒状の支持部材５４と、これらの支持部材５４に固定された樋状部材５５とを有する。
【００４２】
前記樋状部材５５は、底板部５５ａと、この底板部５５ａの両側縁部から立上る立上部５５ｂ，５５ｃと、一方の立上部５５ｂから横方向に延びるフランジ部５５ｄとを有する。この樋状部材５５は、胴体部３にすくい上げ板２０を設けていない場合は、そのフランジ部５５ｄが胴体部３に接触し、胴体部３にすくい上げ板２０を設けている場合は、そのフランジ部５５ｄがすくい上げ板２０に接触し、かつその長さ方向の一端部５５ｅが回転方向の前方位置に、また他端部５５ｆが回転方向の後方位置になるように、回転方向に対して傾斜して設けられる。
【００４３】
図６に示す実施形態は、回転ドラム２にすくい上げ板２０を取付けている場合で、樋状部材５５のフランジ部５５ｄがすくい上げ板２０に接触し、かつその一端部５５ｅがすくい上げ板２０の回転方向の前方位置に、また他端部５５ｆがすくい上げ板２０の回転方向の後方位置になるように、回転方向に対して傾斜して設けられている。この樋状部材５５の他端部５５ｆが、すくい上げ板２０の後縁部２０ｂよりも食み出す場合には、図示するように、フランジ部５５ｄと一体に、すくい上げ板２０と面一状またはそれよりも若干低くなるようにガイド部材５５ｇを設ける。
【００４４】
前記樋状部材５５の底板部５５ａは、一端部５５ｅ側では幅広状に、また他端部５５ｆ側では幅狭状に形成されている。それによって、前述の製品排出プレート部材４０から遠い部分にある粉粒体製品を、効果的に製品排出プレート部材４０側に流動させることができるようになっている。
【００４５】
なお、上記製品排出プレート部材４０および製品排出促進スコープ部材５０は、製品排出促進スコープ５０を回転方向の前方側のすくい上げ板２０に、製品排出プレート部材４０を回転方向の後方側のすくい上げ板２０になるように、それぞれ異なるすくい上げ板２０位置に配設する。この場合、製品排出プレート部材４０および製品排出促進スコープ部材５０が隣接するすくい上げ板２０に設けられてもよいし、１個または複数個離れたすくい上げ板２０に設けられてもよい。それによって、回転ドラム２内の粉粒体製品が、回転ドラム２の回転動作によって、まず先行する製品排出促進スコープ部材５０によってすくい上げられて製品排出プレート部材４０側に流動させられ、この製品排出プレート部材４０側に流動させられた粉粒体製品が、後続の製品排出プレート部材４０によって製品排出部３０から排出される。
【００４６】
次に、上記の粉粒体処理装置の動作について説明する。まず、粉粒体原料の投入時，粉粒体の処理時，サンプリング品質確認時，点検時および清掃時などには、製品排出プレート部材４０および製品排出促進スコープ部材５０を、粉粒体処理装置に取付けない。したがって、開口部７から回転ドラム２内への粉粒体原料を投入時，サンプリング品質確認時，点検時および清掃時などの作業は、従来と同様に行なえる。
【００４７】
また、粉粒体の処理時には、回転ドラム２内に粉粒体原料を供給し、回転ドラム２を回転駆動源１５によって所定方向に回転駆動すると共に、所定温度に温度制御された気体、例えば乾燥空気が通気チャンネル８に供給され、通気チャンネル８から通気用多孔部を通って回転ドラム２内に給気される。また、回転ドラム２内の乾燥空気が他の通気用多孔部および通気チャンネル８を介して、回転ドラム２の外部に排気される。
【００４８】
このとき、回転ドラム２に対する給排気は、ダイレクト給気（上部通気用ダクトから給気、下部通気用ダクトから排気）、リバース給気（下部通気用ダクトから給気、上部通気用ダクトから排気）の他、センター給気、すなわち、回転ドラム２の前部（マウスリング）の中心部にセンター通気用ダクトを配設し、センター通気用ダクトから給気、下部通気用ダクトから排気を行なう構成としてもよい。
【００４９】
回転ドラム２内に供給された粉粒体原料は、回転ドラム２内で転動床を形成する。そして回転ドラム２の所定方向への回転動作によって、すくい上げ板２０がない場合は、転動床がその上面部から流動していき、すくい上げ板２０がある場合は、その前縁部２０ａからすくい上げ板２０上にすくい上げられた粉粒体原料が、その後縁部２０ｂから落下する。ダイレクト吸気の場合、胴体部３の上部にある通気用多孔部を通過した乾燥空気の大部分は、すくい上げ板２０との間に形成された通気用通路２３を通り、後縁部での通気用開口部２２を通って回転ドラム２の内部に流入する。また、すくい上げ板２０の前縁部２０ａに前縁部での通気用開口部２１を形成している場合は、通気用多孔部を通った乾燥空気の残部が、この前縁部での通気用開口部２１から回転ドラム２内に流入する。
【００５０】
回転ドラム２内に流入した乾燥空気の大部分は、すくい上げ板２０によってすくい上げられた粉粒体粒子１２が、すくい上げ板２０の後縁部２０ｂから落下する際に、その落下する粉粒体粒子１２，１２間を通り抜けて粉粒体粒子１２を乾燥すると共に、すくい上げ板２０の後縁部での通気用開口部２２から通気用通路２３を通り、通気用多孔部から空気チャンネル８を通って排気用ダクトから外部に放出される。また、回転ドラム２内に供給された乾燥空気の一部は、回転ドラム２底部の粉粒体粒子１２の転動床を通り抜けて粉粒体粒子１２を乾燥すると共に、すくい上げ板２０の前縁部での通気用開口部２１から通気用通路２３に入り、胴体部３の通気用多孔部を通って空気チャンネル８を通って排気用ダクトから外部に放出される。このようにして、すくい上げ板２０の後縁部での通気用開口部２２および前縁部での通気用開口部２１を利用して、粉粒体粒子１２が効果的に乾燥される。
【００５１】
上記のようにして回転ドラム２に対する給排気を行ないつつ、回転ドラム２内の粉粒体粒子（錠剤など）１２の転動床に向けてスプレーノズル１３からコーティング液１４をスプレーする。これにより、粉粒体粒子１２の表面にスプレー液１４中の基材成分が付着乾燥して被複層が形成される（フィルムコーティング）。あるいは、スプレー液１４により粉粒体粒子１２の表面を適当な湿潤状態にし、シュガーなどの粉末を散布添加して粒子表面の被覆を行なう（粉末添加方式：糖衣コーティングなど）。
【００５２】
処理過程において、回転ドラム２内の粉粒体粒子１２は、すくい上げ板２０上を転動し、すくい上げ板２０の後縁部２０ｂからシャワー状に落下して、その後方のすくい上げ板２０上に乗り移る。
【００５３】
上記の構成によると、胴体部３の通気用多孔部を覆う位置にすくい上げ板２０を配設しているので、粉末添加方式を採用する場合でも、粉末添加物が通気用多孔部の通気孔から漏れたり、あるいは、粉末添加物が通気用多孔部の通気孔に付着して目詰まりを起こしたりする心配がない。
【００５４】
したがって、この実施形態の粉粒体処理装置は、回転ドラム２に対するすくい上げ板２０を着脱することなく、単に回転ドラム２の回転数を変更するのみで、粉末添加方式、糖衣コーティングおよびフィルムコーティングのいずれにも最適な状態で使用することができる。
【００５５】
次に、上記粉粒体処理装置の回転ドラム２内から粉粒体製品を排出する場合について説明する。この製品排出時には、図４および図５に示すように、回転ドラム２のマウスリングに、製品排出プレート部材４０および製品排出促進スコープ部材５０を、それぞれの取付孔４１ａ，４１ｂおよび５１ａ，５１ｂを利用して着脱自在に取付ける。このとき、前述のように、製品排出促進スコープ部材５０を回転方向の前方位置に、製品排出プレート部材４０を回転方向に後方位置に配置する。また、製品排出部３０の蓋３２を取外して、製品排出シュート３１の下方に、製品収容容器（図示省略）を配置しておく。
【００５６】
そして、回転ドラム２を回転駆動源１５によって、所定方向，すなわち、粉粒体の処理時と同一方向に回転させる。すると、すくい上げ板２０上にすくい上げられた粉粒体製品が、まず回転方向の前方に位置する製品排出促進スコープ５０の樋状部材５５によってすくい上げられ、かつその底板部５５ａの傾斜面に沿って、順次、製品排出プレート４０側に流動していく。
【００５７】
すると、回転方向の後方に位置する製品排出プレート部材４０が、流動してきた粉粒体製品を傾斜面４５の側縁部４５ａおよび端縁部４５ｂですくい上げ、順次、隣接する製品搬送路４４に搬送していき、さらに基部４３から円弧状部４２を通って、製品排出部３０の製品排出シュート３１に排出され、製品排出シュート３１からその下方に配置している製品収容容器に収容されていく。
【００５８】
次に、他の実施形態の粉粒体処理装置について説明する。この実施形態は、上記の製品排出プレート部材４０を改良して、粉粒体製品の排出効率を向上するようにしたものである。
【００５９】
図７（Ａ）はその製品排出プレート部材６０の正面図を示し、図７（Ｂ）は追加された排出促進プレート部４７の平面図を示す。図８はその回転ドラム２への取付状態の概略斜視図を示す。この製品排出プレート部材６０は、図４および図５に示す製品排出プレート部材４０の縁部４６に沿って、略三角形状の排出促進プレート部４７を設けたものである。この排出促進プレート部４７は、略三角形状の搬送部４７ａと、縁部４６の中途部から胴体部３に向かって固定される側縁部４７ｂと、すくい上げ板２０に接触する端縁部４７ｃと、前記側縁部４７ｂと端縁部４７ｃとを除く部分に設けられた立上部４７ｄとを有する。
【００６０】
なお、追加された排出促進プレート部４７は、製品搬送路４４よりも縁部４６に高さ寸法分だけ、回転ドラム２の回転方向の前方に位置している。それによって、排出促進プレート部４７によってすくい上げられた粉粒体製品が、製品搬送路４４に流動し易くなっている。
【００６１】
また、追加された排出促進プレート部４７は、製品搬送路４４と平行状に配置されてもよいが、製品搬送路４４に対して、回転ドラム２の回転方向の前方に向かって、適当な角度だけ傾斜させることが望ましい。それによって、排出促進プレート部４７によってすくい上げられた粉粒体製品が、製品搬送路４４に流動し易くなっている。
【００６２】
上記の製品排出プレート部材６０によれば、前記製品排出プレート部材４０に比較して、追加された排出促進プレート部４７によっても、すくい上げ板２０上の粉粒体製品がすくい上げられて、製品搬送部４４に移送されるので、回転ドラム２からの粉粒体製品の排出効率が向上する。なお、排出促進プレート部４７の端縁部４７ｃの長さ寸法Ｌを長くすればするほど、すくい上げ板２０上の粉粒体製品のすくい上げ効率が向上するが、長さ寸法Ｌはすくい上げ板２０の大きさを考慮して適宜設定すればよい。
【００６３】
図９はすくい上げ板２０を具備する粉粒体処理装置において、粉粒体製品の排出時に、上記の製品排出促進スコープ部材５０または６０と共に用い得る第２製品排出促進スコープ部材７０の取付け状態の概略斜視図を示す。この第２製品排出促進スコープ部材７０は、マウスリングに取付けられる取付孔７１ａ，７１ｂを有する取付部７１と、この取付部７１からマウスリングにそって円弧状に延びる円弧状部７２と、この円弧状部７２から回転ドラム２の前壁部４に沿って延びる支持部材取付部７３と、この支持部材取付部７３に取付けられた複数の棒状の支持部材７４と、これらの支持部材７４に固定された断面がくの字状の閉止部材７５とを有する。
【００６４】
この第２製品排出促進スコープ部材７０は、前記閉止部材７５が、前方部分７５ａと後方部分７５ｂとを有し、粉粒体製品の排出時に、図１０に示すように、前方部分７５ａを進入阻止部材２４の後方側の斜面部に接触させると共に、後方部分７５ｂをすくい上げ板２０の屈曲部２０ｃに重ね合わせて、前縁部での通気用開口部２１を覆うことによって、この前縁部での通気用開口部２１付近に滞留する粉粒体製品、あるいはこの前縁部での通気用開口部２１を通って通気用通路２３内への粉粒体製品の進入をなくして、全ての粉粒体製品をすくい上げ板２０にすくい上げることができ、効率的に排出することができる。
【００６５】
なお、上記図１〜図８に示す実施形態では、回転ドラム２の胴体部３が多角形状で、かつすくい上げ板２０を有する場合について説明したが、胴体部３が円筒形状の場合、あるいはすくい上げ板２０を有しないものにおいても、同様に実施出来ることは言うまでもない。
【００６６】
また、製品排出プレート部材４０，６０および製品排出促進スコープ部材５０は、それぞれ少なくとも１個設ければよいが、複数個設ければそれだけ粉粒体製品の排出効率が向上する。
【００６７】
また、製品排出促進スコープ部材５０の樋状部材５５は、図示例の構成に限らず、例えば、底板部５５ａは、図示例のように、平板状にする場合のみならず、断面形状が下方に凸状の湾曲状やＶ字状など、種々の変形が可能である。
【００６８】
【発明の効果】
本発明によれば、軸線回りに回転可能な回転ドラムを備え、前記回転ドラムは、筒状でかつその少なくとも一部に通気用多孔部を有する胴体部と、この胴体部に連なる傾斜状の前壁部および後壁部と、前記前壁部の端部に設けられた開口部とを有する粉粒体処理装置において、あるいは、さらに前記回転ドラムの胴体部にすくい上げ板を取付けた粉粒体処理装置において、前記回転ドラム内の製品の排出時に、回転ドラムに着脱自在に取付けられ、その側縁部が前記前壁部に配置されると共に、その胴体部側の端縁部が胴体部またはすくい上げ板に配置される製品排出プレート部材と、前記回転ドラム内の製品の排出時に、前記回転ドラムに着脱自在に取付けられ、その側縁部が胴体部またはすくい上げ板に配置され、前記製品排出プレート部材に向かって製品の流動を促進させる製品排出促進スコープ部材とを設けたことを特徴とするので、回転ドラム内に粉粒体原料を投入時，サンプリング品質確認時，点検時，清掃時および粉粒体の処理時には、製品排出プレート部材や製品排出促進スコープ部材は回転ドラムに取付けられていないので、従来装置と同様に作業することができ、粉粒体製品の排出時は、製品排出プレート部材や製品排出促進スコープ部材を回転ドラムに着脱自在に取付けることによって、粉粒体製品を自動的に排出することができる。
【００６９】
また、従来装置では、その構造上、胴体部にすくい上げ板を設けることができず、したがって粉粒体の転延作用が十分でなかったため、粉粒体を均質に処理することが困難で、粉粒体の処理に長時間を要していたが、本発明ではすくい上げ板を有する装置にも適用でき、粉粒体の転延作用が効率的に行なわれるため、粉粒体を均質処理が可能で処理が短時間で行なえる。
【００７０】
また、上記すくい上げ板を有する構成において、前記すくい上げ板が、胴体部との間に回転ドラムの回転方向の前縁部での通気用開口部を有し、さらに前記回転ドラム内からの粉粒体製品の排出時に、前記回転ドラムに着脱自在に取付けられ、前記前縁部での通気用開口部を閉止する第２製品排出促進スコープ部材を有する構成においては、粉粒体製品の排出時に、回転ドラムに回転方向の前方側のすくい上げ板の後縁部から落下する粉粒体製品が、前記前縁部での通気用開口部で滞留したり、前縁部での通気用開口部に進入することが防止されて、より確実、かつ効率的に回転ドラムからの粉粒体製品の排出が行なえる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a granular material processing apparatus used when manufacturing tablets, soft capsules, pellets, granules, and the like of pharmaceuticals, agricultural chemicals, foods, and the like. More specifically, the present invention relates to granulation, coating, The present invention relates to a granular material processing apparatus including a mechanism for automatically discharging a granular material product that has been subjected to a process such as drying from a rotary drum.
[0002]
[Prior art]
For example, in order to apply a film coating or a sugar coating to a granular particle such as a tablet or a granule, a granular processing apparatus provided with a rotating drum is used. FIGS. 11 and 12 show an example of a basic structure of a granular material processing apparatus provided with a horizontal rotating drum.
[0003]
FIG. 11 is a side view of a granular material processing apparatus having a horizontal rotary drum 2. The rotary drum 2 is disposed in a casing 1 so as to be rotatable about its horizontal axis. The rotary drum 2 is provided at the center of the front end of the front wall 4, the front wall 4 and the rear wall 5, which are connected to the front and rear ends in the axial direction of the body 3. It has an opening 7 formed by a front ring 6 provided. The body 3 is configured as a porous part for ventilation, and an air channel 8 is provided on the outer surface side of the porous part for ventilation. Each air channel 8 extends along the outer surface of the rear wall 5 and communicates with a distributor 9 of the air supply / exhaust device.
[0004]
The distributor 9 is connected to the air supply duct and the exhaust duct. When an arbitrary air channel 8 rotates and moves to a predetermined position, dry air (warm air) flows through the rotary drum 2 through the air channel 8. At the same time, the air in the rotating drum 2 is discharged through another air channel 8. With such a function of the distributor 9, an upward or downward airflow is generated in the rotary drum 2.
[0005]
The front wall portion 4 of the rotary drum 2 extends forward from the body portion 3 in an inclined manner, and an opening portion 7 formed of a ring member such as a front ring 6 is provided at a front end portion thereof. The supply of the powder material into the rotary drum 2 and the discharge of the powder product from the rotary drum 2 are performed through the opening 7.
[0006]
FIG. 12 shows a state in which granulation or coating of the granular material is performed in the rotary drum 2 and shows a vertical cross section orthogonal to the axial direction as viewed from the opening side. The rotary drum 2 is rotated in the direction of the arrow by the drive motor 11, and at the same time, air is supplied and exhausted to form a rolling bed of the granular material 12 in the rotating drum 2. A spray liquid 14 such as a binder liquid or a coating liquid is sprayed from a spray nozzle 13. As a result, the granular particles in the rotary drum 2 are wetted and aggregated, or the base component in the spray liquid adheres to the surface of the granular particles to form a multi-layer.
[0007]
After the granulation or coating treatment is performed as described above, the processed granular material is discharged from the inside of the rotary drum 2. As a mechanism for this, conventionally, there is a hollow inside the front wall of the rotary drum. By projecting a blade in the shape of a circle and rotating the rotating drum at the time of discharge in the opposite direction to that during the processing of the granular material, the granular material product in the rotating drum is guided to the opening by the blade, and the opening is formed. There is known a mechanism for automatically ejecting the paper from the paper. (For example, refer to Patent Document 1).
[0008]
Alternatively, a hollow product discharging means constituted by a plate-like member is protruded from the inner surface of the front wall of the rotating drum, or from the inner surface of the body of the rotating drum to the inner surface of the front wall and the vicinity of the opening. By providing a plate-shaped discharge member protruding and rotating the rotating drum in a direction opposite to that during the processing of the granular material at the time of discharging, the granular product in the rotary drum is opened by the product discharging means, the plate-shaped discharging member. There is known a mechanism for guiding a sheet to an opening and automatically discharging the sheet from an opening (for example, see Patent Document 2).

Japanese Patent No. 2726062 (Column 5, line 27, FIG. 1, and Column 7, line 21, FIG. 5)
[0010]
[Problems to be solved by the invention]
According to the above-described granular material processing apparatus, the granular material can be processed by the forward rotation of the rotary drum 2 and the granular product can be discharged by the reverse rotation of the rotary drum 2. The following problems occur because the protrusions are provided on the inner surface.
[0011]
(1) At the time of processing the powder material (when the rotating drum is rotating forward), the powder 12 in the rotating drum is lifted by the discharge member, and the upper layer of the rolling bed undulates. This makes it difficult to spray the spray liquid 14 uniformly, which may affect the quality of the granular product.
[0012]
(2) When discharging the granular material (during reverse rotation of the rotating drum), the amount of scooping by the discharging member changes according to the remaining amount of the granular material in the rotating drum, so the amount discharged per unit time. Is difficult to adjust.
[0013]
(3) If there is a protrusion due to the discharge member inside the rotating drum, the work at the time of charging the powder material, checking the sampling product visually, pulling out the spray nozzle at inspection, cleaning, etc. is inconvenient. .
[0014]
(4) The rotating drum must be switched between forward rotation and reverse rotation during the processing of the granular material (when the rotating drum is rotating forward) and when discharging the granular material (when the rotating drum is rotating backward). Therefore, a drive source that can rotate forward and backward is indispensable.
[0015]
Therefore, an object of the present invention is to enable reliable automatic discharge of the granular material product, and at the time of processing of the granular material, the discharging member is provided in a protruding manner on the inner surface of the rotating drum, An object of the present invention is to solve the problems of the conventional device described above.
[0016]
[Means for Solving the Problems]
In order to solve the above-described problems, the present invention includes a rotating drum rotatable around an axis, the rotating drum has a cylindrical body and at least a part thereof having a porous portion for ventilation, and the body has In the granular material processing device having a continuous inclined front wall portion and rear wall portion, and an opening provided at an end of the front wall portion, when the granular material product is discharged from the rotating drum, the rotating device rotates. A product discharge plate member detachably attached to the drum, a side edge portion of which is disposed on the front wall portion, and an end edge portion on the body portion side of the drum portion; A product discharge promoting scope member which is detachably attached to the rotating drum when the granular product is discharged, and whose side edge is disposed on the body portion, and which promotes the flow of the granular product toward the product discharge plate member. Characterized by the provision of To provide a formed.
[0017]
The terms "the side edge portion is arranged on the front wall portion", "the end portion on the body portion side is arranged on the body portion" or "the side edge portion is arranged on the body portion" The case where each side edge or the edge is disposed in contact with the front wall or the body, or the case where the side edge or the edge is disposed through a gap smaller than the particle size of the granular material to be processed. Including.
[0018]
According to this configuration, the following various excellent effects can be obtained as compared with a conventional granular material processing apparatus in which a discharge member is fixed in a rotating drum.
[0019]
(1) At the time of discharging the granular product from the rotating drum, a product discharging plate member is detachably attached to the rotating drum, and the product discharge is promoted to promote the flow of the granular product toward the product discharging plate member. Since the scope member is detachably attached, the rotary drum is rotated in a predetermined direction, so that the granular material product in the rotary drum is caused to flow toward the product discharge plate member by the above-described product discharge promoting scope member. In addition, the granular product can be flowed by the product discharge plate member to the mouth ring of the rotating drum. Therefore, the granular product can be automatically and reliably discharged from the rotary drum.
[0020]
(2) Since the product discharge plate member and the product discharge promotion scope member do not exist in the rotary drum during the processing of the powder material, the powder material in the rotary drum is removed by the product discharge plate member and the product discharge promotion scope member. The waving phenomenon does not occur in the upper layer of the rolling bed caused by being lifted. Therefore, the spray liquid can be sprayed uniformly, and a high quality product can be obtained in a short time.
[0021]
(3) Since the change in the amount of picking up by the product discharge plate member and the product discharge promotion scope member due to the residual amount of the granular material product in the rotating drum is small when discharging the granular product, the discharge amount per unit time is reduced. Adjustment is easy.
[0022]
(4) At any time other than when discharging the granular product, since there is no protrusion due to the product discharge plate member and the product discharge promoting scope member in the rotating drum, the raw material is charged into the rotating drum from the opening. In addition, operations such as checking the sampling product visually, pulling out the spray nozzle for inspection, and cleaning can be easily performed.
[0023]
(5) Since the rotating drum is rotated in the same direction during the processing of the granular material and the discharging of the granular product, a driving source that can rotate in only one direction can be used, and the rotation can be performed in the normal or reverse direction. A possible drive source is not necessary. However, this does not preclude the use of a drive source that can be rotated forward and backward for modifying existing equipment or for other reasons.
[0024]
The present invention also includes a rotating drum rotatable around an axis, the rotating drum having a cylindrical body having at least a portion of a porous body for ventilation, and an inclined front wall connected to the body. And a rear wall portion, and an opening provided at an end of the front wall portion, wherein the body portion has a scooping plate attached at a predetermined angle to the body portion. A product discharge plate member detachably attached to the rotating drum when discharging the granular product, the side edge portion of which is disposed on the front wall portion, and the end portion of the body portion side disposed on the scooping plate. When the granular product is discharged from the rotary drum, the granular product is detachably attached to the rotary drum, and a side edge portion thereof is disposed on a scooping plate, and the powder product flows toward the product discharge plate member. Promote product emission Cope member and may be configured to provided.
[0025]
According to the above configuration, not only the same operation as described above can be obtained, but also the scooping plate is attached to the body of the rotary drum. Is lifted up at the leading edge and falls from the trailing edge, so that the agitation action of the granular material is improved, and a high-quality granular material product can be manufactured in a short time. Further, when discharging the granular product, the product discharge plate member and the product discharge promoting scope member are detachably attached to the rotating drum, and the rotating operation of the rotating drum causes the granular product on the scooping plate to discharge the product. The product is made to flow toward the product discharge plate member by the promotion scope member, and the flowed granular product is conveyed toward the opening by the product discharge promotion scope member. Therefore, the granular product can be automatically and reliably discharged from the rotary drum.
[0026]
In the above configuration, the scooping plate has an opening for ventilation at the front edge in the rotation direction of the rotating drum between the body and the body, and further, when discharging the granular material product in the rotating drum, It is good also as composition which has a 2nd discharge promotion scope member detachably attached to a rotating drum, and closes the above-mentioned ventilation opening.
[0027]
According to such a configuration, since the scooping plate has the ventilation opening at the front edge in the rotation direction of the rotary drum, the scooping plate and the body portion pass through the ventilation opening at the time of processing the granular material. The air flows through the ventilation passage between and the air is discharged into the rotating drum from the ventilation opening at the trailing edge, so that the stirring effect of the powder particles falling from the trailing edge of the scooping plate is improved. And the processing of a homogeneous powder can be performed in a short time. When discharging the granular product, the second product discharge promoting scope member is removably attached to the rotating drum, and the ventilation opening at the front edge is closed by the second product discharge promoting scope member. Since the granular product is prevented from staying at the ventilation opening portion at the front edge portion and penetrating below the scooping plate through the ventilation opening portion at the front edge portion, the rotating drum It is possible to reliably discharge the products within the last one.
[0028]
In the above configuration, the product discharge promoting scope member, the second product discharge promoting scope member, and the product discharge plate member may be sequentially arranged from the front to the rear in the rotation direction of the rotating drum.
[0029]
According to the above configuration, the granular product on the scooping plate is caused to flow toward the product discharge plate member by the product discharge promotion scope member along with the rotating operation of the rotary drum in a predetermined direction, and the preceding scooping plate When dropping from the second scooping plate to the subsequent scooping plate, the ventilation opening at the front edge of the subsequent scooping plate is closed by the second product discharge promoting scope member, so that the granular product can be moved to the subsequent scooping plate. Is prevented from staying in the ventilation opening at the front edge portion of the opening or entering the ventilation opening, and the granular product transferred to the subsequent scooping plate is opened by the product discharge plate member. Therefore, the granular product can be automatically and reliably discharged from the rotary drum.
[0030]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, a granular material processing apparatus according to an embodiment of the present invention will be described with reference to the drawings.
[0031]
FIG. 1 is a schematic side view showing a cross section of a part of the granular material processing apparatus according to the first embodiment when granulating or coating a granular material in a rotary drum 2, and FIG. 2 shows a vertical cross section orthogonal to the axial direction as viewed from the side of the section. 1 and 2, the same parts as those in FIGS. 11 and 12 are denoted by the same reference numerals, and a description thereof will be omitted. The difference from FIGS. 11 and 12 is that the rotary drum according to the present invention basically needs to be rotatable only in one direction, so that a rotary drive source 15 rotatable only in a predetermined direction is provided. Further, a scoop-up plate 20 is attached to each of the ventilation porous portions of the body 3 of the rotating drum 2 in such a manner that the front side in the rotating direction of the rotating drum 2 is low and the rear side is high.
[0032]
All the scooping plates 20 attached to the rotating drum 2 have the same trapezoidal shape. The reason for the trapezoidal shape is that the rotary drum 2 has the inclined front wall portion 4 and the rear wall portion 5, and as described above, the scooping plate 20 is lower on the front side in the rotation direction of the rotary drum 2, When the rear side is mounted in an inclined manner, the side edge of the scooping plate 20 on the front edge portion 20a side is in contact with a position near the body portion 3 of the front wall portion 4 and the rear wall portion 5, whereas scooping is performed. This is because the side edge on the rear edge 20b side of the plate 20 is in contact with the front wall 4 and the rear wall 5 at positions separated from the body 3.
[0033]
3, the height dimension h1 (not shown) of the front edge portion 20a in the rotation direction of the rotary drum 2 from the body 3 is larger than the dimension d of the granular material (h1). > D) The ventilation opening 21 at the front edge is provided and attached, and the height h2 (not shown) of the rear edge 20b from the body 3 is equal to the ventilation opening 21 at the front edge. (H2> h1) larger than the height dimension h1 (h2> h1) of the rear edge portion, is provided by a bolt shaft and a nut (not shown) so as to be inclined at a predetermined angle of front low and rear heights. ing. A ventilation passage 23 is formed between the scoop-up plate 20 and the ventilation porous portion of the body portion 3 through which the dry air supplied from the ventilation porous portion passes.
[0034]
As shown in FIG. 3, a front edge portion 20a of the scooping plate 20 has a polygonal shape at a front portion of the scooping plate 20 which forms a ventilation opening 21 at the front edge portion with the body portion 3. Has a bent portion 20c substantially parallel to the body portion 3 of the body. Then, if necessary, a guide for the granular material is provided at a position slightly forward in the rotation direction of the ventilation opening 21 at the front edge of the body 3 so that the granular material can easily ride on the upper surface of the scooping plate 20. A member 24 is provided.
[0035]
Therefore, in the powdery and granular material processing apparatus having the scooping plate 20 described above, when air supply and exhaust are performed by the direct air intake method, the airflow through the air channel 8 at the upper portion of the rotary drum 2 causes the airflow porous portion of the body 3 to ventilate. Dry air supplied into the body 3 through the passage 23 and the ventilation opening 22 at the rear edge 20 b of the scooping plate 20 falls from the rear edge 20 b of the scooping plate 20 at the lower part of the rotary drum 2. After passing between the powder particles 12, 12, the ventilation plate 23 enters the ventilation passage 23 from the ventilation opening 22 of the rear edge 20 b of the scooping plate 20, and passes through the air channel 8 from the ventilation porous portion of the body 3 to rotate the drum. 2, the rolling effect of the granular material particles 12 is improved as compared with the granular material processing device having no scooping plate 20, and uniform processing can be performed in a short time. It can be.
[0036]
Further, since the ventilation opening 21 at the front edge portion is formed in the front edge portion 20a of the scooping plate 20, the rolling bed of the granular material particles 12 near the ventilation opening portion 21 at the front edge portion is formed.

It is bent in a convex shape.
[0041]
FIG. 6 is a perspective view of the product discharge promoting scope member 50 detachably attached to the mouth ring of the rotary drum 2 when discharging the granular product. The product discharge facilitating scope member 50 includes an attachment portion 51 having attachment holes 51a and 51b to the mouth ring, an arc portion 52 extending from the attachment portion 51 along the mouth ring, and an arc portion 52 extending from the attachment portion 51 along the mouth ring. It has a support member mounting portion 53 extending along the front wall portion 4, a plurality of rod-shaped support members 54 mounted on the support member mounting portion 53, and a gutter-like member 55 fixed to these support members 54. .
[0042]
The gutter-shaped member 55 has a bottom plate portion 55a, rising portions 55b and 55c rising from both side edges of the bottom plate portion 55a, and a flange portion 55d extending laterally from one rising portion 55b. The gutter-shaped member 55 has a flange 55 d that contacts the body 3 when the scooping plate 20 is not provided on the body 3, and has a flanged portion when the scooping plate 20 is provided on the body 3. 55d is in contact with the scooping plate 20, and is inclined with respect to the rotation direction so that one end 55e in the length direction is at the front position in the rotation direction and the other end 55f is at the rear position in the rotation direction.

When the other end portion 55f of the gutter-like member 55 protrudes from the rear edge portion 20b of the scooping plate 20, as illustrated, the flange portion 55d and the scooping plate 20 are flush with the scooping plate 20. The guide member 55g is provided to be slightly lower than the guide member 55g.
[0044]
The bottom plate portion 55a of the gutter-like member 55 is formed wide at one end 55e and narrow at the other end 55f. Thus, the powdery product located at a portion far from the product discharge plate member 40 can be effectively made to flow to the product discharge plate member 40 side.
[0045]
In addition, the product discharge plate member 40 and the product discharge promotion scope member 50 are configured such that the product discharge promotion scope 50 is disposed on the front scooping plate 20 in the rotational direction, and the product discharge plate member 40 is disposed on the rear scoop plate 20 in the rotational direction. So that they are arranged at different scooping plate 20 positions. In this case, the product discharge plate member 40 and the product discharge promotion scope member 50 may be provided on the adjacent scooping plate 20 or may be provided on the scooping plate 20 separated by one or more. As a result, the granular product in the rotary drum 2 is firstly scooped up by the preceding product discharge promoting scope member 50 and caused to flow toward the product discharge plate member 40 by the rotating operation of the rotary drum 2, and the product discharge plate The granular product flowed to the member 40 side is discharged from the product discharge unit 30 by the subsequent product discharge plate member 40.
[0046]
Next, the operation of the above-described powdery material processing apparatus will be described. First, the product discharge plate member 40 and the product discharge promotion scope member 50 are connected to the powder and granular material processing apparatus at the time of inputting the powder and granular material, processing of the granular material, checking of sampling quality, inspection and cleaning, and the like. Do not attach to Accordingly, operations such as charging of the granular material into the rotary drum 2 from the opening 7, checking of sampling quality, checking, and cleaning can be performed in the same manner as in the related art.
[0047]
Further, at the time of processing of the granular material, the raw material of the granular material is supplied into the rotary drum 2, and the rotary drum 2 is driven to rotate in a predetermined direction by a rotary drive source 15, and a gas whose temperature is controlled to a predetermined temperature, for example, a dry gas. Air is supplied to the ventilation channel 8, and is supplied from the ventilation channel 8 into the rotating drum 2 through the ventilation porous portion. Further, the dry air in the rotary drum 2 is exhausted to the outside of the rotary drum 2 through another porous portion for ventilation and the ventilation channel 8.
[0048]
At this time, the supply / exhaust air to / from the rotating drum 2 includes direct air supply (air supply from the upper ventilation duct, exhaust air from the lower ventilation duct), and reverse air supply (air supply from the lower ventilation duct, exhaust air from the upper ventilation duct). In addition, a center air supply, that is, a center ventilation duct is provided at the center of the front part (mouth ring) of the rotary drum 2, and air is supplied from the center ventilation duct and exhausted from the lower ventilation duct. Is also good.
[0049]
The granular material supplied into the rotating drum 2 forms a rolling bed in the rotating drum 2. When there is no scooping plate 20 due to the rotating operation of the rotary drum 2 in a predetermined direction, the rolling bed flows from the upper surface thereof, and when the scooping plate 20 is present, the scooping plate is moved from its front edge 20a. The powdered raw material that has been picked up on the surface 20 then falls from the edge 20b. In the case of direct intake, most of the dry air that has passed through the ventilation porous portion at the top of the body portion 3 passes through the ventilation passage 23 formed between the scooping plate 20 and the ventilation air at the rear edge. It flows into the inside of the rotating drum 2 through the opening 22. When the opening 21 for ventilation at the front edge is formed in the front edge 20a of the scooping plate 20, the remaining portion of the dry air that has passed through the porous portion for ventilation is used for ventilation at the front edge. It flows into the rotating drum 2 from the opening 21.
[0050]
Most of the dry air that has flowed into the rotating drum 2 is used when the particulate particles 12 scooped up by the scooping plate 20 fall from the trailing edge portion 20b of the scooping plate 20. , 12 to dry the particulate particles 12, exhaust through the ventilation passage 23 from the ventilation opening 22 at the rear edge of the scooping plate 20, and exhaust through the air channel 8 from the ventilation porous portion. From the air duct. A part of the dry air supplied into the rotating drum 2 passes through the rolling bed of the granular material particles 12 at the bottom of the rotating drum 2 to dry the granular material particles 12 and to dry the leading edge of the scooping plate 20. The air enters the ventilation passage 23 through the ventilation opening 21 in the section, passes through the ventilation porous portion of the body 3, passes through the air channel 8, and is discharged to the outside from the exhaust duct. In this way, the powder particles 12 are effectively dried using the ventilation opening 22 at the rear edge of the scooping plate 20 and the ventilation opening 21 at the front edge.
[0051]
While supplying and exhausting air to and from the rotating drum 2 as described above, the coating liquid 14 is sprayed from the spray nozzle 13 toward the rolling bed of the granular material particles (such as tablets) 12 in the rotating drum 2. As a result, the base component in the spray liquid 14 adheres to the surface of the powder particles 12 and is dried to form a multi-layer (film coating). Alternatively, the surface of the granule particles 12 is brought into an appropriate wet state with the spray liquid 14, and powder such as sugar is dispersed and added to coat the particle surface (powder addition method: sugar coating, etc.).
[0052]
In the processing process, the granular material particles 12 in the rotary drum 2 roll on the scooping plate 20, fall from the rear edge 20b of the scooping plate 20 in a shower shape, and move onto the scooping plate 20 behind the same. .
[0053]
According to the above configuration, since the scooping plate 20 is disposed at a position covering the ventilation porous portion of the body 3, even when the powder addition method is adopted, the powder additive passes through the ventilation holes of the ventilation porous portion. There is no risk of leakage or clogging due to powder additives adhering to the ventilation holes of the ventilation porous portion.
[0054]
Therefore, the powdery or granular material processing apparatus of this embodiment merely changes the number of rotations of the rotary drum 2 without attaching and detaching the scooping plate 20 to and from the rotary drum 2 and can perform any of the powder addition method, sugar coating, and film coating. Can also be used in optimal conditions.
[0055]
Next, a case in which the granular product is discharged from the rotary drum 2 of the granular processing apparatus will be described. At the time of discharging the product, as shown in FIGS. 4 and 5, the mouth ring of the rotating drum 2 uses the product discharging plate member 40 and the product discharging promoting scope member 50, and the respective mounting holes 41a, 41b and 51a, 51b. And attach it detachably. At this time, as described above, the product discharge promotion scope member 50 is disposed at the front position in the rotation direction, and the product discharge plate member 40 is disposed at the rear position in the rotation direction. Further, the lid 32 of the product discharge section 30 is removed, and a product storage container (not shown) is arranged below the product discharge chute 31.
[0056]
Then, the rotary drum 2 is rotated by the rotary drive source 15 in a predetermined direction, that is, in the same direction as that for processing the granular material. Then, the granular product scooped up on the scooping plate 20 is first scooped up by the gutter-like member 55 of the product discharge promotion scope 50 located forward in the rotation direction, and along the inclined surface of the bottom plate portion 55a, It flows to the product discharge plate 40 side sequentially.
[0057]
Then, the product discharge plate member 40 located rearward in the rotation direction picks up the flowing granular product at the side edge 45a and the end edge 45b of the inclined surface 45, and sequentially transports the product to the adjacent product transport path 44. The product is further discharged from the base portion 43 through the arc-shaped portion 42 to the product discharge chute 31 of the product discharge portion 30, and is stored from the product discharge chute 31 in a product storage container arranged below the product discharge chute 31.
[0058]
Next, a granular material processing apparatus according to another embodiment will be described. In this embodiment, the above-described product discharge plate member 40 is improved to improve the discharge efficiency of a granular product.

And a rising portion 47d provided at a portion other than the side edge portion 47b and the end edge portion 47c.
[0060]
The added discharge promoting plate portion 47 is located forward of the rotating direction of the rotary drum 2 by the height of the edge portion 46 relative to the product transport path 44. This facilitates the flow of the granular product scooped up by the discharge promoting plate portion 47 to the product transport path 44.
[0061]
Further, the added discharge promoting plate portion 47 may be disposed in parallel with the product transport path 44, but may have an appropriate angle with respect to the product transport path 44 toward the front in the rotation direction of the rotary drum 2. It is desirable to tilt only. This facilitates the flow of the granular product scooped up by the discharge promoting plate portion 47 to the product transport path 44.
[0062]
According to the above-mentioned product discharge plate member 60, compared with the product discharge plate member 40, the granular product on the scooping plate 20 is also scooped by the added discharge promotion plate portion 47, and the product transport portion 44, the efficiency of discharging the granular product from the rotating drum 2 is improved. Note that the longer the length dimension L of the edge portion 47c of the discharge promoting plate section 47 is, the more the scooping efficiency of the granular product on the scooping plate 20 is improved, but the length dimension L is smaller than that of the scooping plate 20. What is necessary is just to set suitably in consideration of a magnitude | size.
[0063]
FIG. 9 is a schematic diagram showing an attached state of a second product discharge promoting scope member 70 that can be used together with the product discharge promoting scope member 50 or 60 at the time of discharging a granular product in the granular material processing apparatus provided with the scooping plate 20.

And a closing member 75 having a V-shaped cross section.
[0064]
In the second product discharge promoting scope member 70, the closing member 75 has a front part 75a and a rear part 75b, and prevents the front part 75a from entering as shown in FIG. By bringing the rear portion 75b into contact with the rear slope portion of the member 24 and overlapping the rear portion 75b with the bent portion 20c of the scooping plate 20 to cover the ventilation opening 21 at the front edge portion, the front edge portion is formed. All the granules are prevented by preventing the particulate product staying in the vicinity of the ventilation opening 21 or entering the ventilation passage 23 through the ventilation opening 21 at the leading edge into the ventilation passage 23. The body product can be scooped on the scooping plate 20 and can be efficiently discharged.
[0065]
In addition, in the embodiment shown in FIGS. 1 to 8 described above, the case where the body 3 of the rotary drum 2 is polygonal and has the scooping plate 20 is described, but the case where the body 3 is cylindrical or the scooping plate is used. Needless to say, the present invention can be similarly carried out even in the case where there is no 20.
[0066]
At least one product discharge plate member 40, 60 and at least one product discharge promotion scope member 50 may be provided. However, providing a plurality of product discharge members improves the discharge efficiency of the granular product.
[0067]
Further, the gutter-shaped member 55 of the product discharge promoting scope member 50 is not limited to the configuration in the illustrated example. For example, the bottom plate portion 55a is not limited to a flat plate shape as shown in the illustrated example, and the cross-sectional shape is downward. Various modifications such as a convex curved shape and a V-shape are possible.
