【０００１】
【発明の属する技術分野】
本発明は、粉状の医薬品や食品などの粉剤をスティック状容器に収容した分包を製造した後に、箱状容器にまとめて詰めるに先立って、一定数毎に分包を重積して一束にするための分包集積機に関する。
【０００２】
【従来の技術と解決課題】
従来は、スティック状分包は、医薬品や食品の粉末を所定量毎計量してスティック状容器に充填する分包製造機で製造されているが、分包は両端を熱圧着でシールした筒状をなし、筒体内に上記粉末を規定の量を入れて封入された容器である。分包は、分包製造機から順次移送され、これらを所定数毎に箱詰機で箱詰めされる。この箱詰めに際して、スティック状分包は、所定数を予め重ねて重積体に纏められる。分包集積機は、スティック状分包を箱状容器に効率よく詰めるために使用されるものである。
【０００３】
従来の技術について、分包製造機から分包集積機に結ぶコンベア上に（例えばバケットコンベアの中に）は、通常は、一定間隔でスティック状分包を配列するための横溝が移送方向に直角に並べて形成され、分包を分包集積機に移送している。従来の分包集積機は、例えば、実開昭６２−９９５０４号公報に開示のように、一定数の配列された互いに略平行なガイドレーンの一端（入口端）が上記横溝の間隔でコンベアの縁部にコンベアの移送方向に直角に（従って、スティック状の分包に平行に）配置されて、これら多数のガイドレーンはそれぞれの先端（出口端）側が下方に傾斜し且つ互いの間隔が狭められて、箱詰めされるべき箱状容器の開口部に連通するように配置され、他方、コンベアの反対縁部には、ガイドレーンに分包を押し出すためのプッシャーが設けられた構造のものが知られている。
【０００４】
この装置の使用の際は、コンベアにより並べて運ばれた各分包は、ガイドレーンに対応する位置で、プッシャーによりガイドレーン側に押し出されて、ガイドレーンを滑り通って箱内に入ることによって、箱状容器に箱詰めされ、詰め終わった箱状容器がコンベア上に押し出されて移動させると共に、次の空の箱状容器がガイドレーン先端に配置されるようになっている。
【０００５】
然しながら、上記の従来の分包集積機は、箱詰めすべきガイドレーンの列数が決まっているので、１箱に詰めるべき分包の充填数を自由に設定変更調節ができないという問題があった。また、この装置のためには、搬入用のコンベア上の横溝は、すべて分包に占められていることが必要で、若し分包のない空きの溝が残っていると、箱詰めの分包の数が不足する結果になる。このためには、人手により、搬送用コンベア上の空きの溝に分包を補充する必要があった。
【０００６】
また、従来の装置は、ガイドレーンの溝幅が固定されており、その溝幅で流通できる分包の幅が決まるので、ガイドレーンを広幅とすると薄い狭幅の分包には適さず、ガイドレーンを狭幅とすると、より太い分包は通過できないなど、ガイドレーンの溝幅によって適用可能な分包に限りがあった。
【０００７】
さらに、分包を形成する筒体の材質には、紙質や合成樹脂製フィルム等が利用され、硬い材質や柔らかく可撓なものなど種類が多く、また、分包への粉剤等の入れ目、分量によっても分包の撓み易さ曲げ易さなどの性状が大きく変わることがあるが、特に、軟質フィルムなどで滑りの悪い分包や、全体に曲がり易い分包などに対しては、従来の分包集積機は、ガイドレーンの途中で停止して箱内に挿入できず、ガイドレーン内に詰まるか又はガイドレーンからはみ出てしまうというトラブルがあって、従来の装置は、適用可能な材質が滑りやすい材質に限られていた。このように、ガイドレーンの滑りを利用して充填する従来の装置は、分包の材質が柔らかくてしかも摩擦抵抗が大きくて滑り難い分包には、安定的に集積するのに適用できなかった。
【０００８】
本発明は、上記の問題に鑑み、第１に、１箱に詰めるべき分包の充填数、即ち、重積体１束当たりの重積数を任意に変更設定することに対応でき、しかも、分包製造機からの搬送用コンベア上の横溝など所定の位置に分包がないなどの空き溝があっても、重積数が常に正確に過不足なく確保できる様な分包集積機を提供するものである。
【０００９】
本発明は、第２に、分包の外形や厚みに影響されないで、所望の長さ、寸法、形状の異なる分包についても容易に重積できる分包集積機を提供しようとするものである。
本発明は、第３に、分包の包装材質やその柔らかさに依存されずに、所望のどのような材質の分包でも容易に重積できる分包集積機を提供しようとするものである。

【００２０】
【発明の実施の形態】
本発明の分包集積機の実施の具体例を以下に示すが、図１において、この例は、基本構成として、水平回転軸１９周りに回転する回転体１とその回転体１の外縁に放射状に形成した複数の集積倉２を備えた回転集積装置と、その回転体の前下側に集積倉２に分包９を１個づつ充填して重積体９０にする充填装置５と、充填装置５に対して回転体の後方に、集積倉２から重積体９０を外して輸送する重積体搬出装置６とが備えられている。
【００２１】
回転集積装置は、回転体１が、モータ（不図示）駆動によりステッピング回転可能とされた水平回転軸１９に固定されており、回転体１の外縁に、多数の集積倉２２、この例は、１２個の集積倉２が回転軸１９に対して放射状に等しい角度で形成されている。水平回転軸１９の回転ステップは、１ステップで集積倉２の数に応じて、隣接する２つの集積倉２の間の角度だけ回転するように規制されている。
【００２２】
上記集積倉２は、該回転体１の外縁にその半径方向に開口して分包の重積体９０の側部を保持する案内枠体１１、１１と、案内枠体１１、１１の内側で分包を軸側で重積体９０を受止して重積体９０を付勢する可動支持台２１と、から成っている。集積倉２の両側一対の案内枠体は、分包の幅に対応する幅のスロットを形成する一対の突片が回転体の両側にぞれぞれ突設されて、形成されているものが好ましい。
【００２３】
回転集積装置は、回転体１の外周に円弧状の外周ガイド３が固定され、該ガイド３の内周面３０が集積倉２内に収納した重積体９０の外側側部を摺動状態で支持し、可動支持台２１が付勢すると、重積体９０は円弧状外周ガイド３の内周面３０で受止されて、集積倉２内に重積体９０が定置されることになる。円弧状の外周ガイド３は、充填装置５の位置に始端部３１として始まり、重積体搬出装置６の位置で終端部３２として終わり、外周ガイド３が存在する区間で集積倉２内に収納した重積体９０を支持案内することになり、回転体１をステップ回転させるごとに、回転体１が重積体９０を充填装置５側から重積体搬出装置６側へ移動させることができる。
【００２４】
充填装置５は、この例では、リフト手段のリフトとして、傾斜した充填用チェーンコンベア５１上にコンベア移送方向に等間隔に左右一対の分包リフト突起５２、５２が固定されており、充填用チェーンコンベア５１は、分包製造機（不図示）からの搬送用コンベア８と交叉しており、当該搬送用コンベア８に等間隔で、順次移送されて来るスティック状分包９・・・を上記の分包リフト突起５２が拾い上げる。このため、充填用チェーンコンベア５１の移動は、搬送用コンベア８の移動と完全に同期化されている。
【００２５】
分包リフト突起５２は、回転体１の外縁に開口して重積倉２の開口位置に、案内枠１１、１１の内側に該突起が保持しているスティック状分包を押し込むことが可能なように配設されて、各分包リフト突起５２がそれぞれの分包９を重積倉２に押し込む度に分包９が、重積体９０に順次さらに重積される。分包が所定数に達すれば、１ステップだけ回転させて、重積した集積倉２を円弧状の外周ガイド３の区間に送る。
【００２６】
他方の重積体搬出装置６は、この例では、略水平方向に移動する搬出用チェーンコンベア６３上に、後に左右一対の集合体用受止突起６１と、前に集合体用の受止突起６２と、が固定されて一個の集合体受止部材６０とされ、チェーンコンベア６３上には、多数の集合体受止部材６０（但し、一部のみ図示）が配列されている。集合体受止部材６０の集合体用受止突起６１、６２は、回転体１の多数の集積倉２が水平状態となる位置に、集積倉２中の重積体９０を受止できる位置に定置できるように配置される。回転体１の回転に伴って上方より降下してきた集積倉２が水平になった時点で、重積体９０が集合体用受止突起６１、６２間に受け取られ、チェーンコンベアの移動により、集合体用受止部材６０と共に重積体９０が集積状態のままで搬出される。
【００２７】
本発明のこの実施形態の分包集積機の基本的な動作を、図２と図３に示すと、図２は、分包集積作業の途中にあり、外周ガイドの範囲内にある８個の集積倉２ａ〜２ｈは、重積体９０を収容している。図２は、充填装置５により分包を充填していた集積倉２ａ中に重積体９０が所定の分包数に達した瞬間を示し、この時点では、重積体搬出装置には、集積倉２の直下の集合体用受止突起６１ａ、６２ａは空の状態で待機されている。
【００２８】
図３は、回転体１が１ステップ分だけ回転した状態を示し、充填し終わった集積倉２ａは、１ステップ分回転することにより、重積体９０の側部が上記の外周ガイド３の始端部３１側の内周面３０に係止されて集積倉２ａ内に保持される。
【００２９】
回転体１のこの１ステップ分の回転により、集合体受止部材６０の集合体用受止突起６１ａ、６２ａの直上にあった集積倉２ｈが降下して、集積倉２ｈ内の重積体９０がそのまま重積状態で、集合体用受止突起６１ａ、６２ａの間に受け取られ、集積倉２ｈは、この位置では、外周ガイド３の終端部３２の外側にあるので、もはや外周ガイド３に拘束されないから、集合体９０は、集合体用受止突起６１、６２のコンベア６３の移動と共に、引き出され、搬出される。
【００３０】
１ステップ分回転する度に、図２のように、充填装置５の前には、移動してきた空の集積倉２の開口部に位置するので、再び、充填装置５により、分包リフト突起５２、５２により分包９が順次集積倉２に押し込まれて充填されて重積される。予め設定された数だけの分包９が重積される度に、図３のように回転体１が１ステップ回転し、上記の動作を繰り返し、重積体９０が順次搬出される。
【００３１】
本発明の実施例をさらに詳細に述べると、まず回転集積装置の回転体１、集積倉２及び円弧状外周ガイド３の詳細については、上記図１ないし図３と共に、次の図４を参照して以下に例を述べる。
【００３２】
図４において、回転体１は、両側二枚の回転板１０ａ、１０ｂが隔設された二重構造とされ、回転板１０ａは、中心軸より伸びて分包の幅に対応する幅のスロット１３を形成する一対の突片の枠体１１、１１と他方の回転板１０ｂの同様の一対の突片の枠体１２、１２が、両側一対のスロット１３を形成し、回転軸１９側から放射状に突設されて案内枠体１１、１２とされ、案内枠体１１、１２とスロット１３とを以て集積倉２とされる。
このような一対のスロット形成のための突片状の案内枠体１１、１１、１２、１２が、本例では、回転体１の円周に１２組形成されて、１２個の集積倉２が形成されている。
【００３３】
回転体１の上記の両側二枚の回転板１０ａ、１０ｂの間には、さらに、回転板２０が固定されており、この回転板２０の外周には内部に１２本のロッド２２が挿通されて他端側が放射状に突出されているが、これらのロッド２２は、回転軸１９側より半径方向に向けて摺動可能にしかもスロット１３、１３の中間位置に突出されている。各ロッド２２の先端には、上記案内枠体１１、１２の内側であって、四隅が案内枠体に案内された可動支持台２１が取付けられている。可動支持台２１は多数の分包９から成る重積体９０を半径方向に且つ回転軸１９側で、受止して、円弧状外周ガイド３側に重積体９０を付勢されている。付勢のために、ロッドには、この回転板２０の外周と可動支持台２１との間でコイルスプリングが巻き付けられて、回転軸１９から半径方向に弾性力を可動支持台２１に与えている。
【００３４】
図４において、上記の円弧状の外周ガイド３の細部については、回転体１の外縁に沿って計４層の互いに離間した外周ガイド３ａ〜３ｄから成り、ガイド３ａ、３ｂの間及び、ガイド３ｃ、３ｄの間には、回転体１の上記両側にスロット用の突片状の枠体１１と枠体１２の先端がそれぞれ突入した状態にされている。
上記の可動支持台２１と円弧状の各層の外周ガイド３ａ〜３ｄの内周面３０との間に積み重ねた分包９の重積体９０を挟持し且つ回転体１の回転に伴って、円弧状外周ガイド３の内周面３０に摺動できるようにされている。
【００３５】
本例では、さらに側部用の円弧状外周ガイド３ｅが、回転体１の外縁の片方に設けられて、外周ガイド３ｅの側面が各集積倉２に積み重ねられ分包９の先端部を揃えるようにして重積体９０の端部を案内し、重積体９０の集積倉２での位置決めと重積体のずれの防止を図っている。
【００３６】
充填装置５は、図４にその詳細が示されるが、図１と共に参照して、本例では、分包９を１つづつ持ち上げるリフト手段として、傾斜した充填用チェーンコンベア５１に等間隔に設けた左右一対の分包用のリフト突起５２が利用され、これらの突起の間には、リフト突起５２の移動に平行に分包を支持して摺動させる分包支持ガイド５６が設けてある。
【００３７】
充填装置５の充填用チェーンコンベア５１は、その上側のスプロケット５３を回転体１の下部ないし直下あたりに軸支され（図１と図２）、上側のスプロケット５３とさらに下側のスプロケット（不図示）との間に、更に、コンベア５１のチェーンが張設されている。各分包用のリフト突起５２は、概して外形Ｌ字形で、底辺５９とこれに略直角の垂直片５８とから成り、その角部５４だけが充填用チェーンに回動可能に軸支され、その底辺５９は、所定の傾斜角で固定された軌道ガイド５５の上を摺動可能に乗り、その垂直片５８が軌道ガイド５５に対して略直角に立設され、分包９を受止する。
【００３８】
分包支持ガイド５６と軌道ガイド５５とは、その方向が、回転体１の両側一対のスロット１３を以て形成した集積倉２の開口部に向けて一定の傾動角を以て固定されている。そのチェーンのスプロケット５３の回転によりチェーン５１を引き上げると、分包リフト突起５２も引き上げられ、分包支持ガイド５６と軌道ガイド５５は、分包リフト突起５２上の分包９を集積倉２の開口部に案内する。
【００３９】
分包支持ガイド５６と軌道ガイド５５の上端部（不図示）は、集積倉２の開口部直前で、即ち突片状の案内枠体１１、１２の先端で停止され、両ガイド、５５、５６で案内されてきた分包リフト突起５２が、当該上端で外れて、スプロケットに巻かれるチェーンと共にスプロケット周りを回る。さらに、この際には、開口部付近の固定部材（不図示）に係合ピン５７が取り付けられ、上昇してきた分包リフト突起５２の垂直部５８がこの係合ピン５７に当接すると分包リフト突起５２（５２ａ）がその角部の軸支部５４を中心に後方に傾動しながらチェーン５１と共にスプロケット５３周りを回るようにされ（図２を参照）、分包リフト突起５２が重積体９０に衝突するのを回避している。
【００４０】
このような充填装置５は、充填用チェーンコンベア５１が、上述のように分包製造機からの搬送用コンベア８と交叉して、当該搬送用コンベア８に等間隔で、順次移送されて来るスティック状分包９・・・を分包リフト突起５２が拾い上げて、上記回転体１の外縁に開口して案内枠体１１、１２の開口位置で、案内枠体の内側の集積倉２に該突起５２が保持しているスティック状分包を押し込んで集積倉２内に順次横積みされ、該突起５２は、押し込むと同時に、上述のように後方に傾動して、重積体９０との衝突を回避することができる。
このようにして上記充填装置は、分包リフト突起が、チェーンコンベアに後傾可能に枢支され、集積倉に分包を押し入れた直後に後方に傾動して重積体を回避するようにしてあるので、充填用チェーンコンベアに配列した多数の分包リフト突起５２がそれぞれ分包９を集積倉２内に重積するのを続けることができる。
【００４１】
上記の円弧状外周ガイド３については、その始端部３１は、分包リフト突起５２上に乗せられたスティック状分包９が通過できて、且つ、１ステップ以内の僅かな回転で、重積された一番外側の分包９に係止できるように近接して配置されている。
【００４２】
そこで、充填位置で集積中に、集積倉２内への重積体９０が所定の数に達したときには、回転体１を１ステップだけ回転させれば、その集積倉２が１ステップ始端部３１側へ移動し、その中の重積体９０は外周ガイド３の始端部３１における内周面３１に係止されて安定して保持される。次の空の集積倉２が充填位置に移動するので、充填装置５が引き続き充填作業を行う。このように、ステップ回転を急速に行うので集積倉２の切替え時にも充填装置５は中断させる必要はない。
【００４３】
この充填装置５には、分包を集積倉２に順次押し込む際に重積された分包が集積倉２から下落離脱するのを防止するに重要な分包シャッタ手段８が設けられている。
上記の分包シャッタ手段は、集積倉の開口部近傍に配置されて、各分包の両端部の支持と通過とを交互に成しうる左右一対の可動受止片と、可動受止片を左右開閉駆動する駆動手段とから成り、受止片は、駆動手段により、リフト上の分包通過の際に左右に遠ざかり、両端部の支持の際に左右から近づいて集積倉の分包を受止するように繰り返し駆動されることができる。
【００４４】
この分包シャッタ手段８は、図４において、この例では、分包リフト突起５２の通過する充填用チェーンコンベアの両側で、充填すべき集積倉２の開口部位置の直前に配置されて、分包リフト突起５２上に乗せた各分包９の両端部を支持することと通過させることと交互に成し得る左右一対の可動受止片８０ａ、８０ａとこれらの可動受止片を左右開閉駆動する開閉駆動手段とから成っている。受止片８０ａ、８０ａは、開閉駆動手段により、リフト上の分包通過の際に左右に遠ざかり、両端部の支持の際に左右から近づいて集積倉２内下端にある分包を受止するように繰り返し駆動される。
【００４５】
駆動手段については、一般には、可動受止片の開閉駆動が分包リフト突起５２の移動と同期させて、分包リフト突起５２のチェーンコンベアの回転と連動して各突起５２の移動と同期した回転盤に対してカム機構、リンク機構ないしクランク機構により、可動受止片の開閉を駆動させることができる。
【００４６】
左右一対の可動受止片は、通常は、閉の状態で集積倉２内のもっとも外側の分包の少なくとも両端部を支持してその落下を防止するもので、集積倉２に充填する際のリフト突起５２により各分包９が受止片８０ａ、８０ａ間を通過する僅かな時間だけ可動受止片を開けるのが好ましい。
【００４７】
この目的で、本例では、図４及び図５には、上下に隣接して左右１対の可動受止片８０ａ、８０ａと８０ｂ、８０ｂの２対を使用して、開閉を同期させた分包シャッタ手段８の例が示してある。この例は、可動受止片の開閉操作は、クランク機構で行っている。上側一対の受止片８０ａ、８０ａと下側１対の受止片８０ｂ、８０ｂは、シャッタ駆動回転軸（不図示）に固定された回転盤８５ａ、８５ａ、８５ｂ、８５ｂの偏心位置を旋回支点とするクランク棒８３のピボット８４を有してクランクを構成し、旋回支点支点ピボット８４と連結されたクランク棒８３１が、受止片８０ａ、８０ｂを往復させる往復軸８３と連結され、回転盤８５ａ、８５ｂの回転により受止片８０ａ、８０ｂを往復させる。
【００４８】
この実施例は、上側（集積倉２に近い側）の左右の受止片８０ａ、８０ａを駆動する２つの回転盤８５ａ、８５ａは互いに反対回転し、さらに上下の受止片を駆動する２つの回転盤８５ａと８５ｂもまた互いに反対回転し、これら４つの回転盤の回転軸（不図示）は、分包リフト突起５２とその分包９の通過周期と回転周期とが完全に同期している。
【００４９】
図６は、左右２対で計４つの受止片の挙動を解説するが、図６（Ａ）は、４つの受止片８０ａ、８０ａと８０ｂ、８０ｂがすべて開の状態であり、この状態は、シャッタ駆動回転軸上の回転盤８５ａ、８５ａ、８５ｂ、８５ｂの支点ピボット８４ａ、８４ａ、８４ｂ、８４ｂの位置が回転盤８５ａ・・・の後方斜め位置にある。この状態が、全ての受止片８０ａ・・・の開の状態を定める回転盤上の支点ピボット８４ａ、８４ａ、８４ｂ、８４ｂの基準位置とされる。この状態では、受止片８４ａ、８４ａ、８４ｂ、８４ｂ間を分包９が通過できる。
【００５０】
図６（Ｂ）は、図６（Ａ）の位置の回転盤８５ａ、８５ａ、８５ｂ、８５ｂがそれぞれ９０°づつ反対回転した時、支点ピボット８４ａ、８４ａ、８４ｂ、８４ｂの旋回により上側の受止片８０ａ、８０ａが前進して閉となり（ここで、受止片８４ａ、８４ａの先端部が分包９の両端部を係止できる程度に相近づければ閉じると言い、完全に受止片同士が接触するまで閉じる必要はない、以下同じ）、下側の受止片８０ｂ、８０ｂは、一旦後退した後に僅かに前進して開の状態のままであるが、受止片８０ａ・・・全体として閉止しており、上側の受止片８０ａ、８０ａ間で重積体９０の下側の分包９がその端部を受止されて、重積体９０の落下を防止している。
【００５１】
図６（Ｃ）は、さらに、回転盤８５ａ、８５ａ、８５ｂ、８５ｂがさらにそれぞれ９０°づつ互いに反対回転した時の上側の受止片８０ａ、８０ａが閉のままで、下側の受止片８０ｂ、８０ｂが前進して閉の状態にあり全体として閉止しており、図６（Ｄ）は、さらに、回転盤８５ａ、８５ａ、８５ｂ、８５ｂがそれぞれ９０°づつ反対回転した時の上側の受止片８０ａ、８０ａは後退して開となるが、下側の受止片８０ｂ、８０ｂが閉の状態にあり全体として閉止している。この時点では、別の分包９を乗せた次の分包リフト突起５２が、受止片８０ａ・・・の直前に来ている。
【００５２】
さらに、回転盤８５ａ、８５ａ、８５ｂ、８５ｂがそれぞれ９０°づつ反対回転すると、図６（Ａ）の状態に戻り、上下の受止片８０ａ、８０ａ、８０ｂ、８０ｂがともに後退していて、開の状態にあり、受止片間の分包リフト突起５２が通過し、突起上の分包が、それまでの重積体９０の下に重ねられ且つ押し上げられて、分包リフト突起５２の回避動作の時には、図６（Ｂ）の状態にあり、上下の受止片が、重積体９０の下部を支持してその下落を阻止している。
【００５３】
本発明は、このような分包シャッタ手段８を備えているので、仮に、次に登って来る分包リフト突起５２上に分包が載ってない場合でも、上下の受止片８０ａ、８０ａ、８０ｂ、８０ｂは、同様に作動して、今まで集積倉２に集積した重積体９０を保持しながら空の分包リフト突起５２を通過させることができ、さらに次の重積操作を継続することが可能である。従って、分包製造機から順次移送されるスティック状分包に欠番があっても、カウンターを備えていて、一定数ごとに重積した重積体９０を得ることができる。
【００５４】
このように分包シャッタ手段８は、閉時間を長くして重積した分包の下端を支持し、開時間を分包リフト突起５２の通過に要する時間程度に短くして、分包の両端を支持する時間を確保してある。このような開閉時間制御のための機構には、上記のクランク機構の他に、例えば、カム機構を利用して、左右１対だけの可動受止片で構成してもよい。
【００５５】
他方の重積体搬出装置６は、図７に示すが、略水平方向に移動する搬出用チェーンコンベア６３上に等間隔に設けた前後に左右一対の集合体用受止突起６１、６１、６２、６２を設けて１組の集合体受止部材とされ、多数の組の集合体受止部材が該コンベア上に配列されているものを採用している。前側の受止突起６１、６１と後側の受止突起６２、６２との間に重積体９０を挟持される。さらに、チェーン６３の両側には、支持台６５がチェーン方向に延伸するように固定されており、前後の受止突起６１、６２間の重積体９０を下から支えて、チェーン移動により前後の受止突起６１、６２間の重積体９０を移送することができる。
【００５６】
集合体受止部材６１、６２の前側の左右一対の集合体用受止突起６２、６２は、連動する第１の系統の左右一対のチェーン６３ｂ、６３ｂに固定され、その後側の当該突起６１、６１は別系統の一対のチェーン６３ａ、６３ａに固定され、２つの系統のチェーン６３ａ、６３ｂの相対距離を微調整することによって、前後の集合体用受止突起６１、６２の距離を、収容すべき重積体９０の厚みに対応した距離に調整できる。
【００５７】
これらチェーンコンベア６３ａ、６３ｂは、チェーンを張り渡すための端部スプロケット６４（図１参照）が、上記の収納倉２を備えた回転体１を両側から挟むように外側領域に配置されており、このスプロケット６４は、前側の集合体用受止突起６２、６２が、重積倉から重積体９０を受け取る位置にあるとき、後の受止突起６１、６１がスプロケット６４を通過する直前の周囲にあって、後方に傾くようにされて、定置されている。この状態は、前後の受止突起６１、６２が上方に僅かに開く形態であるので、集積倉２から重積体９０を受け取るのに好ましい。重積体９０を受け取った後に前後の受止突起は、チェーン６３の移動とともに、前方に移動して、チェーンの張設された直線部に入れば、後側の突起６１、６１も直立して前後の受止突起６１、６２が重積体９０を挟持するようにされている。
【００５８】
チェーンコンベア６３の周回に従って回動する集合体受止部材６１、６２が、上記回転体１の集積倉２内に重積されている重積体９０を受け取る位置で停止できるように調節され、回転体１のステップ回転に同期して、チェーンコンベア６３も間欠移動するようになっている。このようにして、回転体１がステップ回転する毎に、チェーンコンベア６３上の集合体受止部材６１、６２が、集積体９０を支持台６５に受け取っては、間欠的に搬出される。このような重積体搬出装置６は、分包の重積体９０を搬出し、箱詰めのための箱詰機に直接、又は重積体９０の検査機などを経由して移送される。
【００５９】
なお、上記実施の形態は、回転体に重積倉２を形成するために、回転体１には、スロットを形成する一対の突片状の案内枠体を使用したが、単に一対の円板の外縁に半径方向に切欠き部を形成して、スロットとしたものでもよく、要は、分包を横積みに積み重ねて保持するものであればよい。
また、回転体１は軽量であるのが、回転体１はステップ回転は急速になされるので好ましい。この点から、回転体は、好ましくは、アルミニウム製又は合成樹脂製であるものが軽量であるので好ましい。
【００６０】
なお、以上の実施の形態では、回転体１に形成して重積倉２の数を１２とした例であるが、充填装置５と重積体搬出装置６とが、充填する重積倉と搬出する重積倉に対応するように、適宜、重積倉の数を決めればよい。
また、充填装置５のコンベアの傾斜角度は、３０°〜６０°が可動受止片による分包の押し上げに好都合で、重積体搬出装置のためのコンベアを水平とすれば、搬出過程での重積体９０の取扱に便利である。充填装置５のコンベアの傾斜角度か６０°である場合は、重積倉の数は、６、１２、２４から選ぶことができる。傾斜角度を４５°とすれば、重積倉の数は、８、１６などと選ぶこともできる。
【００６１】
上記実施の形態として、リフトとして、チェーンコンベアに定間隔で多数突設した突起を利用したが、これに代えて、斜め上方に昇降するプッシャーを設けて、分包を集積倉２に１個づつ押し上げるようにしてもよい。尤も、上記実施の形態のチェーンコンベアを利用したリフト装置が、分包を高速に安定して重積できる利点がある。
【００６２】
【発明の効果】
本発明の分包集積機によれば、分包製造機から輸送された分包を連続的に重積体に纏めることができ、しかも、重積して充填の際には滑りを利用しないので、分包の外形や厚みに影響されないで、所望長さ、寸法、形状の分包を容易に重積でき、さらに、分包の包装材質やその柔らかさに依存されずに、所望材質のどのような分包でも容易に重積できる。
【００６３】
また、各分包は、開口側から押し入れて所要数になるまで自由に重積することができ、重積体１個当たりの分包数を自由に設定することができる。
【００６４】
さらに、下方から所望の数の分包を集積倉内に重積させることができ、しかも、１箱に詰めるべき分包の充填数、即ち、重積体１束当たりの重積数を任意に変更設定することに対応でき、しかも、分包製造機からのコンベア上の所定の位置に分包が欠けていてリフトに空きがあっても、重積数が常に正確に過不足なく確保できる。
【００６５】
本発明の他の形態によれば、充填装置が、リフトの持ち上げ方向と集積倉の重積方向とを略一致させて、該リフト手段が、傾斜したチェーンコンベアに突出状態で取り付けられた複数の対の分包リフト突起から構成したので、各分包を連続的に且つ高速で重積することができ、分包集積作業の生産性を高くすることができる。
【００６６】
また、本発明の他の形態によれば、分包シャッタ手段により、受止片は、リフト通過後、分包の両端部を支持して落下を防止するので、集積倉に分包を受止でき、しかも、分包製造機からのコンベア上の所定の位置に分包が欠けていてリフトに空きがあっても、空のリフトの通過と重積体の支持が可能であるので、重積数が常に正確に過不足なく確保できる特徴がある。
【００６７】
さらに、本発明の他の形態によれば、重積体搬出装置は、コンベアの周回により、集合体用受止突起が回転体の集積倉中の重積体を一括して順次受止して集積倉から搬出することができる。

BACKGROUND OF THE INVENTION
In the present invention, after manufacturing a sachet containing powdered medicines and foods in a stick-like container, the sachets are stacked in a certain number prior to packing in a box-like container. The present invention relates to a packing and accumulating machine for bundling.
[0002]
[Prior art and solutions]
Conventionally, stick-shaped sachets are manufactured with a sachet making machine that measures a predetermined amount of powder of pharmaceuticals and foods and fills them into stick-shaped containers. A container in which a prescribed amount of the above powder is placed in a cylinder. The sachets are sequentially transferred from the sachet making machine, and are packed in a boxing machine every predetermined number. At the time of this boxing, a predetermined number of stick-shaped packages are stacked in advance in a stack. The package stacking machine is used to efficiently pack stick-shaped packages into a box-shaped container.
[0003]
With respect to the prior art, on the conveyor connecting from the packaging production machine to the packaging stacker (for example, in the bucket conveyor), the transverse grooves for arranging stick-shaped packaging at regular intervals are usually perpendicular to the transport direction. The sachets are transferred to a sachet accumulator. For example, as disclosed in Japanese Utility Model Laid-Open No. 62-99504, a conventional packing and stacking machine has one end (inlet end) of a fixed number of arranged guide lanes substantially parallel to each other at the interval between the transverse grooves. Arranged at the edge at right angles to the conveying direction of the conveyor (and thus parallel to the stick-shaped package), these multiple guide lanes are inclined downward on the tip (exit end) side and are spaced from each other. And is arranged to communicate with the opening of the box-shaped container to be packed, and on the other hand, the opposite edge of the conveyor is provided with a pusher for pushing the package into the guide lane. It has been.
[0004]
When using this device, each package carried side by side by a conveyor is pushed out to the guide lane side by a pusher at a position corresponding to the guide lane, slips through the guide lane, and enters the box. The box-shaped container is packed in a box-shaped container, and the packed box-shaped container is pushed onto the conveyor and moved, and the next empty box-shaped container is arranged at the tip of the guide lane.
[0005]
However, the above-described conventional packaging and accumulating machine has a problem that the number of packings to be packed in one box cannot be freely set and changed because the number of guide lanes to be packed is determined. Also, for this device, it is necessary that all the lateral grooves on the carry-in conveyor are occupied by the packaging, and if there is an empty groove that does not contain any packaging, Result in a shortage of numbers. For this purpose, it was necessary to manually fill the empty grooves on the conveyor for transportation.
[0006]
Further, since the groove width of the guide lane is fixed in the conventional apparatus, and the width of the package that can be circulated is determined by the groove width, if the guide lane is wide, the guide lane is not suitable for a thin narrow package. When the width of the lane is narrow, a thicker package cannot be passed, and the applicable package is limited depending on the groove width of the guide lane.
[0007]
Furthermore, as the material of the cylinder forming the sachet, paper quality or synthetic resin film is used, and there are many types such as hard materials and soft and flexible ones. Depending on the quantity, the properties such as ease of bending and ease of bending may change greatly. Especially, for non-slip wrapping with soft film, etc. The packaging and stacking machine stops in the middle of the guide lane and cannot be inserted into the box, and there is a problem that it is clogged in the guide lane or protrudes from the guide lane. It was limited to slippery materials. As described above, the conventional apparatus for filling by utilizing the sliding of the guide lane cannot be applied to the packing that is soft and has a high frictional resistance and is difficult to slip, so that it can be stably accumulated. .
[0008]
In view of the above problems, the present invention can first cope with arbitrarily changing and setting the number of packings to be packed in one box, that is, the number of stacks per stack of stacks, Providing a packaging and stacking machine that can always ensure the number of stacks without excess or deficiency even if there is a vacant groove such as a transverse groove on a conveyor for transportation from a packaging production machine. To do.
[0009]
Secondly, the present invention intends to provide a packing and stacking machine that can easily stack even different packings having different lengths, dimensions, and shapes without being affected by the outer shape and thickness of the packing. .
Thirdly, the present invention intends to provide a packaging and stacking machine that can easily stack any packaging of any desired material without depending on the packaging material and the softness of the packaging. .

DETAILED DESCRIPTION OF THE INVENTION
A specific example of implementation of the packaging and accumulating machine of the present invention is shown below. In FIG. 1, this example shows a rotating body 1 rotating around a horizontal rotating shaft 19 and a radial shape on the outer edge of the rotating body 1 as a basic configuration. A rotary stacking device having a plurality of stacking chambers 2 formed in the above, a filling device 5 that fills the stacking chamber 2 one by one into the stacking chamber 2 on the front lower side of the rotating body to form a stack 90, and filling On the rear side of the rotating body with respect to the apparatus 5, there is provided a stacking body unloading device 6 that removes the stacking body 90 from the accumulation chamber 2 and transports it.
[0021]
In the rotary stacking device, the rotating body 1 is fixed to a horizontal rotating shaft 19 that can be stepped and rotated by driving a motor (not shown). The twelve accumulation chambers 2 are formed at equal angles radially with respect to the rotation shaft 19. The rotation step of the horizontal rotation shaft 19 is regulated to rotate by an angle between two adjacent accumulation racks 2 in one step according to the number of accumulation warehouses 2.
[0022]
The accumulation chamber 2 includes guide frame bodies 11 and 11 that open in the radial direction at the outer edge of the rotating body 1 and hold the side portions of the stacking body 90 of the packaging, and inside the guide frame bodies 11 and 11. The package includes a movable support 21 that receives the stack 90 on the shaft side and biases the stack 90. The pair of guide frames on both sides of the accumulation chamber 2 are formed by a pair of projecting pieces forming a slot having a width corresponding to the width of the packaging projecting on both sides of the rotating body. preferable.
[0023]
In the rotary stacking device, an arc-shaped outer peripheral guide 3 is fixed to the outer periphery of the rotating body 1, and the inner peripheral surface 30 of the guide 3 slides on the outer side portion of the stacked body 90 housed in the stacking chamber 2. When the movable support base 21 is urged, the stacked body 90 is received by the inner peripheral surface 30 of the arc-shaped outer peripheral guide 3, and the stacked body 90 is placed in the accumulation chamber 2. The arc-shaped outer periphery guide 3 starts as a start end portion 31 at the position of the filling device 5, ends as a terminal end portion 32 at the position of the stacking material unloading device 6, and is stored in the stacking unit 2 in a section where the outer periphery guide 3 exists. The stacked body 90 is supported and guided, and each time the rotating body 1 is rotated stepwise, the rotating body 1 can move the stacked body 90 from the filling device 5 side to the stacked body unloading device 6 side.
[0024]
In this example, in the filling device 5, as a lift of the lift means, a pair of left and right package lift protrusions 52, 52 are fixed on the inclined filling chain conveyor 51 at equal intervals in the conveyor transfer direction. The conveyor 51 crosses the transporting conveyor 8 from the packaging production machine (not shown), and the stick-shaped packagings 9... That are sequentially transferred to the transporting conveyor 8 at regular intervals. The parcel lift protrusion 52 picks up. For this reason, the movement of the chain conveyor 51 for filling is completely synchronized with the movement of the conveyor 8 for conveyance.
[0025]
The package lift protrusion 52 can be pushed into the opening position of the stack 2 and the stick-shaped package held by the protrusion inside the guide frames 11, 11 can be pushed into the outer edge of the rotating body 1. Thus, each time the respective package lift protrusions 52 push the respective packages 9 into the stack 2, the packages 9 are sequentially stacked on the stack 90. When the number of packages reaches a predetermined number, the stack is rotated by one step, and the stacked stack 2 is sent to the section of the arc-shaped outer peripheral guide 3.

The assembly receiving projections 61a and 62a immediately below the warehouse 2 are kept in an empty state.
[0028]
FIG. 3 shows a state in which the rotating body 1 has been rotated by one step, and the accumulated granule 2a that has been filled is rotated by one step so that the side portion of the stacked body 90 becomes the starting end of the outer circumferential guide 3 described above. It is locked to the inner peripheral surface 30 on the part 31 side and held in the accumulation chamber 2a.
[0029]
Due to this one-step rotation of the rotating body 1, the accumulation granule 2 h just above the aggregate receiving projections 61 a and 62 a of the aggregate receiving member 60 is lowered, and the stack 90 in the accumulation granule 2 h Are received between the assembly receiving projections 61a and 62a in the stacked state as they are, and in this position, the accumulation chamber 2h is outside the terminal end portion 32 of the outer circumferential guide 3, and thus is no longer restrained by the outer circumferential guide 3. Accordingly, the assembly 90 is pulled out and carried out with the movement of the conveyor 63 of the assembly receiving projections 61 and 62.
[0030]
As shown in FIG. 2, each time it rotates by one step, it is located in front of the filling device 5 at the opening of the empty accumulation chamber 2 that has moved. , 52, the sachets 9 are sequentially pushed into the stack 2 and filled and stacked. Each time a predetermined number of packages 9 are stacked, the rotating body 1 rotates one step as shown in FIG. 3, and the above operation is repeated, and the stacked bodies 90 are sequentially carried out.
[0031]
The embodiment of the present invention will be described in more detail. First, with respect to the details of the rotating body 1, the stacking unit 2 and the arcuate outer periphery guide 3 of the rotating stacking apparatus, refer to FIG. An example is given below.
[0032]

A rotating plate 20 is further fixed between the two rotating plates 10 a and 10 b on both sides of the rotating body 1, and twelve rods 22 are inserted into the outer periphery of the rotating plate 20. Although the other end side protrudes radially, these rods 22 are slidable in the radial direction from the rotating shaft 19 side, and are protruded at an intermediate position between the slots 13 and 13. At the tip of each rod 22, there is attached a movable support base 21 which is inside the guide frame bodies 11 and 12 and whose four corners are guided by the guide frame body. The movable support 21 receives a stack 90 composed of a large number of parcels 9 in the radial direction and on the rotating shaft 19 side, and biases the stack 90 on the arcuate outer periphery guide 3 side. For urging, a coil spring is wound around the rod between the outer periphery of the rotary plate 20 and the movable support base 21, and an elastic force is applied to the movable support base 21 in the radial direction from the rotary shaft 19. .
[0034]
In FIG. 4, the details of the arc-shaped outer peripheral guide 3 are composed of a total of four outer peripheral guides 3a to 3d spaced along the outer edge of the rotating body 1, and between the guides 3a and 3b and the guide 3c. 3d, the tips of the slot-like frame body 11 and the frame body 12 are inserted into the both sides of the rotating body 1 respectively.
A stack 90 of the stacked packages 9 is sandwiched between the movable support base 21 and the inner peripheral surface 30 of the outer peripheral guides 3a to 3d of each arc-shaped layer, and the rotation of the rotating body 1 causes a circular motion. The inner peripheral surface 30 of the arc-shaped outer peripheral guide 3 can be slid.
[0035]
In this example, an arc-shaped outer peripheral guide 3e for the side portion is further provided on one side of the outer edge of the rotating body 1, and the side surfaces of the outer peripheral guide 3e are stacked on the respective stacking units 2 so as to align the front end portions of the parcels 9. Thus, the end of the stacked body 90 is guided to position the stacked body 90 in the accumulation chamber 2 and prevent the stacked body from shifting.
[0036]
The details of the filling device 5 are shown in FIG. 4. Referring to FIG. 1 as well, in this example, the filling device 5 is provided at equal intervals on the inclined filling chain conveyor 51 as lift means for lifting the parcels 9 one by one. Further, a pair of left and right lifting lift projections 52 are used, and between these projections, a packing support guide 56 for supporting and sliding the packing parallel to the movement of the lift projection 52 is provided.
[0037]
The chain conveyor 51 for filling of the filling device 5 is pivotally supported by the upper sprocket 53 below or just below the rotating body 1 (FIGS. 1 and 2), and the upper sprocket 53 and the lower sprocket (not shown). ), A chain of the conveyor 51 is further stretched. Each of the lift projections 52 for packaging is generally L-shaped and includes a bottom 59 and a vertical piece 58 substantially perpendicular to the base 59, and only the corner 54 is pivotally supported by the filling chain. The base 59 is slidably mounted on the track guide 55 fixed at a predetermined inclination angle, and the vertical piece 58 is erected substantially perpendicular to the track guide 55 to receive the package 9.
[0038]
The direction of the package support guide 56 and the track guide 55 is fixed with a certain tilt angle toward the opening of the accumulation chamber 2 formed by the pair of slots 13 on both sides of the rotating body 1. When the chain 51 is pulled up by the rotation of the sprocket 53 of the chain, the packing lift protrusion 52 is also lifted, and the packing support guide 56 and the track guide 55 connect the packing 9 on the packing lift protrusion 52 to the opening of the stacker 2. Guide to the department.
[0039]
The upper end portions (not shown) of the packaging support guide 56 and the track guide 55 are stopped immediately before the opening of the accumulation chamber 2, that is, at the tips of the projecting piece-shaped guide frames 11, 12, and both guides 55, 56 are stopped. The package lift protrusion 52 guided in step S2 is released at the upper end and rotates around the sprocket together with the chain wound around the sprocket. Further, at this time, the engaging pin 57 is attached to a fixing member (not shown) near the opening, and when the vertical portion 58 of the rising lifting lift protrusion 52 comes into contact with the engaging pin 57, the packaging is performed. The lift protrusion 52 (52a) is rotated around the sprocket 53 together with the chain 51 while tilting backward about the pivotal support 54 at the corner (see FIG. 2). To avoid colliding with.
[0040]
In such a filling device 5, the filling chain conveyor 51 crosses the transfer conveyor 8 from the packaging production machine as described above, and is sequentially transferred to the transfer conveyor 8 at equal intervals. The package lift protrusion 52 picks up the package 9 and opens to the outer edge of the rotating body 1 so that the protrusion protrudes into the accumulation chamber 2 inside the guide frame body at the opening position of the guide frame bodies 11 and 12. The stick-shaped packages held by 52 are pushed in and stacked horizontally in the stacking chamber 2, and at the same time as being pushed, the protrusions 52 are tilted backward as described above to collide with the stack 90. It can be avoided.
In this way, the above-mentioned filling device is such that the package lift protrusion is pivotally supported by the chain conveyor so that it can be tilted backward, and immediately after the packing is pushed into the accumulation warehouse, it is tilted backward to avoid the stack. As a result, it is possible to continue stacking the parcels 9 in the stacking chamber 2 by the large number of parcel lift protrusions 52 arranged on the chain conveyor for filling.
[0041]
As for the arc-shaped outer peripheral guide 3 described above, the starting end portion 31 can be stacked with a slight rotation within one step through which the stick-shaped package 9 placed on the package lift protrusion 52 can pass. Further, they are arranged close to each other so that they can be locked to the outermost package 9.
[0042]
Therefore, when the number of stacked bodies 90 in the stacking chamber 2 reaches a predetermined number during stacking at the filling position, if the rotating body 1 is rotated by one step, the stacking block 2 becomes the one-step start end 31. The stacked body 90 is locked to the inner peripheral surface 31 at the start end portion 31 of the outer peripheral guide 3 and is stably held. Since the next empty accumulation warehouse 2 moves to the filling position, the filling device 5 continues the filling operation. As described above, since the step rotation is rapidly performed, the filling device 5 does not need to be interrupted even when the accumulation warehouse 2 is switched.
[0043]
The filling device 5 is provided with a packaging shutter means 8 which is important for preventing the stacked packages from dropping down from the stacking chamber 2 when the packages are sequentially pushed into the stacking chamber 2.
The above-described packaging shutter means includes a pair of left and right movable receiving pieces that are arranged in the vicinity of the opening of the accumulation chamber and can alternately support and pass through both ends of each packaging, and a movable receiving piece. The receiving piece is driven left and right when passing the packing on the lift, and approaches the left and right when supporting both ends by the driving means. It can be driven repeatedly to stop.
[0044]
In FIG. 4, this packaging shutter means 8 is arranged on the both sides of the filling chain conveyor through which the packaging lift projections 52 pass, just before the opening position of the accumulation chamber 2 to be filled. A pair of left and right movable receiving pieces 80a and 80a that can be alternately supported by and supported by both ends of each of the parcels 9 placed on the bag lift protrusion 52, and a left and right opening / closing drive of these movable receiving pieces And opening / closing drive means. The receiving pieces 80a and 80a are moved to the left and right when passing the packing on the lift by the opening / closing drive means, and approach the left and right when supporting both ends to receive the packing at the lower end in the accumulation chamber 2. It is driven repeatedly.
[0045]
As for the driving means, generally, the opening / closing drive of the movable receiving piece is synchronized with the movement of the packing lift protrusion 52, and is synchronized with the movement of each protrusion 52 in conjunction with the rotation of the chain conveyor of the packing lift protrusion 52. The movable receiving piece can be opened and closed by a cam mechanism, a link mechanism or a crank mechanism with respect to the rotating disk.
[0046]
The pair of left and right movable receiving pieces normally support at least both ends of the outermost package in the accumulation chamber 2 in a closed state to prevent the fall, and when the accumulation chamber 2 is filled It is preferable that the movable receiving piece is opened by the lift protrusion 52 only for a short time when each of the parcels 9 passes between the receiving pieces 80a and 80a.
[0047]
For this purpose, in this example, in FIGS. 4 and 5, two pairs of left and right movable receiving pieces 80a, 80a and 80b, 80b adjacent to each other are used to synchronize opening and closing. An example of the packet shutter means 8 is shown. In this example, the opening / closing operation of the movable receiving piece is performed by a crank mechanism. The upper pair of receiving pieces 80a, 80a and the lower pair of receiving pieces 80b, 80b are pivoted on the eccentric positions of the rotary plates 85a, 85a, 85b, 85b fixed to the shutter drive rotation shaft (not shown). The crank rod 831, which constitutes a crank having a pivot 84 of the crank rod 83, and is connected to the pivot fulcrum pivot 84, is connected to the reciprocating shaft 83 that reciprocates the receiving pieces 80a, 80b, and the rotary disc 85a. , 85b causes the receiving pieces 80a and 80b to reciprocate.
[0048]
In this embodiment, the two rotary plates 85a and 85a for driving the left and right receiving pieces 80a and 80a on the upper side (the side close to the stacking unit 2) rotate opposite to each other, and further, the two rotating plates for driving the upper and lower receiving pieces The turntables 85a and 85b also rotate opposite to each other, and the rotation axes (not shown) of these four turntables are completely synchronized with the passage period and the rotation period of the package lift protrusion 52 and its package 9. .
[0049]
FIG. 6 illustrates the behavior of a total of four receiving pieces in two pairs on the left and right, but FIG. 6A shows that the four receiving pieces 80a, 80a and 80b, 80b are all open. The positions of the fulcrum pivots 84a, 84a, 84b, 84b of the rotary plates 85a, 85a, 85b, 85b on the shutter drive rotary shaft are obliquely rearward of the rotary plates 85a. This state is used as a reference position for the fulcrum pivots 84a, 84a, 84b, 84b on the turntable that defines the open state of all the receiving pieces 80a. In this state, the parcel 9 can pass between the receiving pieces 84a, 84a, 84b, 84b.
[0050]
FIG. 6B shows the upper side receiving by turning of the fulcrum pivots 84a, 84a, 84b, 84b when the turntables 85a, 85a, 85b, 85b in the position of FIG. The pieces 80a, 80a move forward and close (here, the receiving pieces 84a, 84a are said to close if the ends of the receiving pieces 84a, 84a are close enough to lock both ends of the packaging 9, and the receiving pieces are completely The lower receiving pieces 80b and 80b are slightly moved backward after being retracted and remain in an open state, but the receiving pieces 80a. And the end of the lower package 9 between the upper receiving pieces 80a and 80a is received by the lower end 9 to prevent the stacked body 90 from falling.
[0051]
FIG. 6C further shows that the upper receiving pieces 80a and 80a are closed when the turntables 85a, 85a, 85b and 85b are further rotated by 90 ° from each other, and the lower receiving pieces are closed. 80b and 80b move forward and are closed as a whole, and are closed as a whole. FIG. 6 (D) further shows the upper receiving when the turntables 85a, 85a, 85b, and 85b are each rotated by 90 °. The stop pieces 80a and 80a are retracted and opened, but the lower receiving pieces 80b and 80b are closed and closed as a whole. At this time, the next package lift protrusion 52 on which another package 9 is placed has come immediately before the receiving pieces 80a.
[0052]
Furthermore, when the turntables 85a, 85a, 85b, 85b rotate counterclockwise by 90 °, the state returns to the state shown in FIG. 6A, and the upper and lower receiving pieces 80a, 80a, 80b, 80b are all retracted and opened. In this state, the package lift protrusion 52 between the receiving pieces passes, and the package on the protrusion is overlapped and pushed up under the previous stack 90 to avoid the package lift protrusion 52 6B, the upper and lower receiving pieces support the lower portion of the stack 90 and prevent its drop.
[0053]
Since the present invention is provided with such a packaging shutter means 8, even if the packaging is not placed on the packaging lift projection 52 that is to be climbed next, the upper and lower receiving pieces 80a, 80a, 80b and 80b operate in the same manner, and can pass the empty sachet lift protrusion 52 while holding the stack 90 accumulated in the stack 2 until now, and continue the next stack operation. It is possible. Therefore, even if there is a missing number in the stick-shaped package sequentially transferred from the package manufacturing machine, it is possible to obtain the stacked body 90 provided with a counter and stacked in a certain number.
[0054]
In this way, the packaging shutter means 8 supports the lower end of the stacked packages that have been stacked by extending the closing time, shortens the opening time to the time required for the passage of the packaging lift protrusion 52, and both ends of the packaging. Time to support is secured. In addition to the crank mechanism described above, the mechanism for controlling the opening / closing time may be composed of, for example, only one pair of left and right movable receiving pieces using a cam mechanism.
[0055]
As shown in FIG. 7, the other stack unloading device 6 includes a pair of left and right assembly receiving protrusions 61, 61, 62 provided on the unloading chain conveyor 63 that moves in a substantially horizontal direction at equal intervals. , 62 is used as one set of assembly receiving members, and a plurality of sets of assembly receiving members are arranged on the conveyor. The stack 90 is sandwiched between the front receiving protrusions 61 and 61 and the rear receiving protrusions 62 and 62. Further, the support bases 65 are fixed to both sides of the chain 63 so as to extend in the chain direction. The stack 90 between the front and rear receiving protrusions 61 and 62 is supported from below, and the front and rear are moved by moving the chain. The stack 90 between the receiving protrusions 61 and 62 can be transferred.
[0056]
The pair of left and right assembly receiving projections 62, 62 on the front side of the assembly receiving members 61, 62 are fixed to the pair of left and right chains 63b, 63b of the first system to be interlocked, and the projection 61 on the rear side, 61 is fixed to a pair of separate chains 63a and 63a, and accommodates the distance between the front and rear assembly receiving projections 61 and 62 by finely adjusting the relative distance between the two chains 63a and 63b. The distance corresponding to the thickness of the power stack 90 can be adjusted.
[0057]
The chain conveyors 63a and 63b are arranged in an outer region so that end sprockets 64 (see FIG. 1) for stretching the chain sandwich the rotating body 1 having the above-described storage 2 from both sides, The sprocket 64 has a peripheral structure immediately before the rear receiving protrusions 61 and 61 pass through the sprocket 64 when the front receiving protrusions 62 and 62 are in a position to receive the stacked body 90 from the stack. There, it is made to incline backward and is fixed. In this state, the front and rear receiving protrusions 61 and 62 are slightly opened upward, so that it is preferable to receive the stack 90 from the stack 2. After receiving the stack 90, the front and rear receiving protrusions move forward with the movement of the chain 63 and enter the straight portion where the chain is stretched, so that the rear protrusions 61 and 61 also stand upright. The front and rear receiving protrusions 61 and 62 are configured to sandwich the stacked body 90.
[0058]
  The assembly receiving members 61 and 62 that rotate according to the rotation of the chain conveyor 63 are adjusted so that they can be stopped at a position where they receive the stacked body 90 that is stacked in the accumulation chamber 2 of the rotating body 1. Synchronously with the step rotation of the body 1, the chain conveyor 63 is also moved intermittently. In this way, each time the rotating body 1 rotates stepwise, the assembly receiving members 61 and 62 on the chain conveyor 63 cause the assembly 90 to move.To support stand 65Once received, it is taken out intermittently. Such a stack unloading device 6 unloads the stacked packages 90 and transports them directly to a boxing machine for boxing or via an inspection machine for the stack 90.
[0059]
In the above embodiment, in order to form the stack 2 in the rotating body, the rotating body 1 uses a pair of projecting piece-shaped guide frames that form slots. A slot may be formed by forming a notch in the outer edge in the radial direction. In short, it may be anything as long as the packages are stacked and held horizontally.
Further, it is preferable that the rotating body 1 is lightweight because the rotating body 1 is rapidly stepped. In this respect, the rotating body is preferably made of aluminum or synthetic resin because it is lightweight.
[0060]
In addition, in the above embodiment, although it is the example which formed in the rotary body 1 and made the number of the stack | stacks 2 into 12, the stacking | stacking warehouse which the filling apparatus 5 and the stack | stacking body carrying-out apparatus 6 are filled What is necessary is just to determine the number of stacking | stacking holds suitably so that it corresponds to the stacking | stacking storage to carry out.
Further, the inclination angle of the conveyor of the filling device 5 is 30 ° to 60 °, which is convenient for pushing up the sachet by the movable receiving piece, and if the conveyor for the stacking device carrying device is horizontal, in the carrying out process This is convenient for handling the stack 90. When the inclination angle of the conveyor of the filling device 5 is 60 °, the number of stacked warehouses can be selected from 6, 12, and 24. If the angle of inclination is 45 °, the number of stacks can be selected as 8, 16, etc.
[0061]
As the above embodiment, as the lift, a number of protrusions protruding at regular intervals on the chain conveyor are used. Instead, pushers that move up and down obliquely are provided, and the sachets are placed one by one in the stacking unit 2. It may be pushed up. However, the lift device using the chain conveyor of the above embodiment has an advantage that the packages can be stacked stably at high speed.
[0062]
【The invention's effect】
  According to the packing and collecting machine of the present invention,Since the parcels transported from the parcel making machine can be continuously packed into stacks, and they are stacked and do not use sliding when filling, they are not affected by the outer shape and thickness of the parcels. In addition, it is possible to easily stack the desired lengths, dimensions, and shapes of the packages, and it is possible to easily stack any packages of the desired material without depending on the packaging material and the softness of the packages.
[0063]
  AlsoEach package can be pushed in from the opening side and stacked freely until the required number is reached, and the number of packages per stacked body can be set freely.
[0064]
  furtherIn addition, a desired number of packages can be stacked in the accumulation chamber from below, and the number of packages to be packed in one box, that is, the number of stacks per stack of stacks can be arbitrarily changed In addition, even if the package is missing at a predetermined position on the conveyor from the package manufacturing machine and the lift is vacant, the number of stacks can always be ensured accurately and accurately.
[0065]
  According to another aspect of the invention,Since the filling device is configured to substantially match the lifting direction of the lift and the stacking direction of the accumulation warehouse, the lifting means is composed of a plurality of pairs of package lifting protrusions attached to the inclined chain conveyor in a protruding state. Each sachet can be stacked continuously and at high speed, and the productivity of the sachet stacking operation can be increased.
