Description
図1は、本発明の一実施形態である製袋包装機1の斜視図である。製袋包装機1は、食品等の被包装物を袋詰めするための機械である。製袋包装機1は、主として、組合せ計量ユニット2と、製袋包装ユニット3と、フィルム供給ユニット4とから構成される。
図2は、製袋包装ユニット3の概略的な構成を示す斜視図である。以下の説明において、「前(正面)」、「後(背面)」、「上」、「下」、「左」および「右」からなる6つの方向を、図2に示されるように定義する。
成形機構13は、チューブ13aとフォーマ13bとを有する。チューブ13aは、上端および下端が開口している、円筒形状の部材である。チューブ13aの上端の開口には、組合せ計量ユニット2から供給される被包装物Cが投入される。フォーマ13bは、チューブ13aを取り囲むように配置されている。フィルム供給ユニット4のフィルムロールから繰り出されてきたフィルムFは、チューブ13aとフォーマ13bとの間の隙間を通過する際に、チューブ13aに巻き付いて筒状に成形される。チューブ13aおよびフォーマ13bは、製造する袋Bの大きさに応じて取り替えることができる。
プルダウンベルト機構14は、チューブ13aに巻き付いたフィルムFを吸着しながら下方に搬送する。プルダウンベルト機構14は、主として、駆動ローラ14a、従動ローラ14bおよび一対のベルト14cを有する。一対のベルト14cは、図2に示されるように、チューブ13aの左右両側においてチューブ13aを挟むように配置され、筒状に成形されたフィルムFを吸着する機構を有する。プルダウンベルト機構14は、駆動ローラ14aおよび従動ローラ14bによって一対のベルト14cが回転駆動することで、筒状に成形されたフィルムFを下方に搬送する。
縦シール機構15は、筒状に成形されたフィルムFを縦方向(図2では、上下方向)にシールする。縦シール機構15は、チューブ13aの正面側に配置される。縦シール機構15は、駆動機構(図示せず)によって、チューブ13aに近づくように、あるいは、チューブ13aから遠ざかるように前後方向に移動する。
横シール機構17は、筒状フィルムFcを横方向(図2では、左右方向)にシールする。横シール機構17は、成形機構13、プルダウンベルト機構14および縦シール機構15の下方に配置される。図3は、横シール機構17の概略的な側面図である。図3において、紙面に垂直な方向は、左右方向である。横シール機構17は、第1回転体50aおよび第2回転体50bを有する。図3の紙面内において、第1回転体50aは、筒状フィルムFcの左側に位置し、第2回転体50bは、筒状フィルムFcの右側に位置している。
横方向駆動機構55は、図3に示されるように、主として、ボールねじ80a、第1ナット81、第2ナット82、第3連結ロッド85および第4連結ロッド86を有する。横方向駆動機構55は、第1水平移動板61aおよび第2水平移動板61bを、図3において両矢印で示される前後方向に移動させる機構である。
次に、横シール機構17の詳細な構成について説明する。図5は、横シール機構17の第1回転体50aおよび第2回転体50bの斜視図である。図6は、第1回転体50aに取り付けられた第1ホーン51aおよびその周辺部材の斜視図である。
第1回転体50aは、回転軸C1を中心に回転する旋回軸94,95と、旋回軸94に相対回転可能に支持されているレバー91d,92dと、旋回軸95に相対回転可能に支持されているレバー91e,92eとを有する。旋回軸94は、第1水平移動板61aに軸支され、旋回軸95は、第1水平移動板62aに軸支されている。
以下、便宜上、図6に示されるユニットをホーンユニット51と呼ぶ。ホーンユニット51は、主として、第1ホーン51aと、3つの振動素子511と、4つの円柱状の共振体513とから構成される。第1ホーン51aは、第1アンビル51bと共に筒状フィルムFcを挟むホーン本体である。第1ホーン51aは、後述するように、ホーン支持体71によって支持されている。図7は、ホーンユニット51の平面図である。図8は、図7の線分VIII−VIIIにおける断面図である。図9は、図7の線分IX−IXにおける断面図である。なお、以下の説明は、第2ホーン52bを有するホーンユニットにも適用可能である。
次に、ホーンユニット51の第1ホーン51aを支持するホーン支持体71について説明する。図10は、ホーンユニット51に取り付けられたホーン支持体71の概略的な平面図である。図10において、ホーン支持体71は、ハッチングされた領域で示されている。以下の説明は、第2ホーン52bにも適用可能である。
次に、横シール機構17の電力供給機構について説明する。図5に示されるように、第1回転体50aの回転軸C1の延長上には、第1スリップリング101が設けられ、第2回転体50bの回転軸C2の延長上には、第2スリップリング102が設けられている。第1スリップリング101および第2スリップリング102は、回転する導体と、固定されて回転しない導体との間を、連続的かつ電気的に接続する導電回転リングである。第1スリップリング101は、第1回転体50aと共に回転する振動素子511に電力を供給し、第2スリップリング102は、第2回転体50bと共に回転する振動素子521に電力を供給する。
最初に、製袋包装機1が被包装物Cを袋Bに充填する動作について説明する。フィルム供給ユニット4から成形機構13に供給されたフィルムFは、チューブ13aに巻き付けられて筒状に成形され、プルダウンベルト機構14によって下方に搬送される。チューブ13aに巻き付けられたフィルムFは、上下方向に延びている両端部が重ね合わせられている。筒状に成形されたフィルムFの重なり部分は、縦シール機構15によって縦方向にシールされ、筒状フィルムFcが形成される。
本実施形態に係る製袋包装機1では、ホーン支持体71は、第1ホーン51aから延びる4つの共振体513に連結されている第1支持部材73と、筒状フィルムFcの横シール時に加圧部72によって力が加えられる第2支持部材74とを有している。第1支持部材73は、第2支持部材74と、連結部材75を介して連結されている。
以上、本発明の一実施形態について説明したが、本発明は上記実施形態に限定されるものではなく、発明の要旨を逸脱しない範囲で種々の変更が可能である。
本実施形態では、第1支持部材73の第1中央部73aは、左右方向の両端の共振体513が固定される一対の端部固定部73bの間に位置している。しかし、第1支持部材73の第1中央部73aは、第1ホーン51aおよび第1アンビル51bに挟まれている筒状フィルムFcの両端の間に位置してもよい。
本実施形態では、第1支持部材73の第1中央部73aは、左右方向の両端の共振体513が固定される一対の端部固定部73bの間に位置している。しかし、第1支持部材73の第1中央部73aは、左右方向の中央に位置する一対の共振体513が固定される、一対の中央固定部73cの間に位置してもよい。
