Description
本発明の実施形態に係る製袋包装機100の概略構成図を図1に示す。製袋包装機100は、ポテトチップスなどの被包装物を筒状に成形したフィルムで覆い、フィルムを縦方向および横方向にシールして、被包装物が入った袋を製造する機械である。
成形機構1は、チューブ11と、フォーマー12とを有している。チューブ11は、上下端が開口している円筒形状の部材である。チューブ11の上端の開口部には、被包装物が投入される。本実施形態では、被包装物の例として、ポテトチップスCを用いる。フォーマー12は、チューブ11を取り囲むように配置されている。フォーマー12は、フィルム供給部から送られたシート状のフィルムFが、フォーマー12とチューブ11との間を通るときに筒状フィルムFmに成形されるような形状を有している。筒状フィルムFmは、フィルムFの水平方向の両端部が互いに重なっている重なり部分Foを有する。筒状フィルムFmの重なり部分Foは、チューブ11の長手方向に延びるように形成される。チューブ11およびフォーマー12は、製造する袋の大きさに応じて取り替えることができる。
縦シール機構2は、プルダウンベルト機構23によって下方に搬送される筒状フィルムFmの重なり部分Foに、超音波振動および圧力を与えて縦方向にシールする機構である。縦シール機構2の外観図を図2に示す。縦シール機構2は、ホーン21とアンビル22とを有している。ホーン21は、超音波振動子21aおよびエアシリンダ21bに連結される金属部材である。超音波振動子21aは、例えば、電極間に圧電セラミックスが挿入された素子であり、電圧をかけることで圧電セラミックスが振動して超音波を発生させる。圧電セラミックスは、酸化チタンや酸化バリウムなどの高純度粉体を高温で焼き固め、分極処理を施した多結晶体セラミックスである。エアシリンダ21bは、内部に供給された圧縮空気のエネルギーを、エアシリンダ21bの長手方向の直動運動に変換する筒状の機械である。アンビル22は、チューブ11の外周面に取り付けられ、ホーン21の先端面と対向して配置される金属部材である。
横シール機構3は、成形機構1および縦シール機構2の下方に配置されている。横シール機構3は、ヒータを内蔵する一対のシールジョー31を有している。一対のシールジョー31は、それぞれ、製袋包装機100の正面から見て筒状フィルムFmの前側および後側に配置されている。一対のシールジョー31は、それぞれ、前後対称の略D字状の軌跡を描くように旋回する。一対のシールジョー31は、旋回の途中で、互いに押しつけ合う状態で筒状フィルムFmを挟み、袋Bの上下の端部となる筒状フィルムFmの部分に圧力および熱を加えてシールする。
被包装物であるポテトチップスCは、製袋包装機100の上方に設けられた計量機(図示せず)によって所定の量だけ計量され、成形機構1のチューブ11の内部に投入される。フィルムFは、フィルム供給部からシート状で送られてきて、成形機構1によって筒状に成形される。成形された筒状フィルムFmは、縦シール機構2によって、プルダウンベルト機構23によって下方に搬送されながら、縦方向にシールされる。
縦シール機構2が筒状フィルムFmを超音波シールする際に、第1フィルム検知センサ51および第2フィルム検知センサ52が、筒状フィルムFmを検知する動作について説明する。本実施形態において、第2フィルム検知センサ52は、メインのフィルム検知機構であり、第1フィルム検知センサ52は、第2フィルム検知センサ52をバックアップする役割を持つフィルム検知機構である。
(4−1)
本実施形態では、第1フィルム検知センサ51は、筒状フィルムFmを縦シールするプロセスにおいて、ホーン21およびアンビル22によって筒状フィルムFmが挟まれているか否かを検知することができる。フィルムFの損傷や蛇行などによって、ホーン21およびアンビル22によって筒状フィルムFmが挟まれていない場合、アンビル22は、ホーン21の超音波振動によってホーン21の先端面と繰り返し衝突する。これにより、ホーン21およびアンビル22は、強度などが低下して劣化しやすくなる。本実施形態では、第1フィルム検知センサ51が、ホーン21およびアンビル22によって筒状フィルムFmが挟まれていないことを検知した場合、制御部29が、超音波発信器24を停止するので、ホーン21およびアンビル22が互いに衝突することを防ぐことができる。従って、本実施形態に係る製袋包装機100は、部品の劣化を防ぐことができる。
本実施形態に係る製袋包装機100は、ホーン21およびアンビル22によって筒状フィルムFmが挟まれているか否かを検知するユニットとして、第1フィルム検知センサ51および第2フィルム検知センサ52の2つのユニットを備える。光電センサである第2フィルム検知センサ52は、筒状フィルムFmを検知する中心的なユニットである。一方、第1フィルム検知センサ51は、筒状フィルムFmを検知する補助的なユニットであり、第2フィルム検知センサ52のバックアップユニットである。本実施形態では、第2フィルム検知センサ52が故障などにより正常に動作しなくなった場合でも、第1フィルム検知センサ51が、ホーン21およびアンビル22によって筒状フィルムFmが挟まれているか否かを検知する。従って、本実施形態に係る製袋包装機100は、フィルム検知機構を1つのみ備える製袋包装機に比べて、筒状フィルムFmの検知に関する信頼性が高い。
本実施形態に係る製袋包装機100では、第1フィルム検知センサ51または第2フィルム検知センサ52が筒状フィルムFmを検知しなかった場合に、制御部29は、超音波発信器24およびプルダウンベルト機構23を停止する制御を行う。これにより、ホーン21の超音波振動、および、筒状フィルムFmの搬送が停止する。従って、本実施形態に係る製袋包装機100は、異常発生時において、製袋包装機100の運転動作を確実に停止することができる。
以上、本発明の実施形態について説明したが、本発明の具体的構成は、本発明の要旨を逸脱しない範囲内で変更可能である。次に、本実施形態に対する適用可能な変形例について説明する。
本実施形態に係る製袋包装機100では、第1フィルム検知センサ51は、超音波発信器24の周波数の出力値をリアルタイムに監視して、この出力値の変動を検出することで、ホーン21およびアンビル22によって筒状フィルムFmが挟まれているか否かを検知する。しかし、第1フィルム検知センサ51は、例えば、超音波発信器24の振幅の出力値をリアルタイムに監視してもよく、また、超音波振動の状態を表す他のパラメータの出力値をリアルタイムに監視してもよい。
本実施形態に係る製袋包装機100では、縦シール機構2は、筒状フィルムFmを検知するための第1フィルム検知センサ51を有するが、横シール機構3が、第1フィルム検知センサ51に相当するフィルム検知機構を有してもよい。本変形例において、横シール機構3は、超音波振動するシールジョー31が筒状フィルムFmを溶着させて横シールする超音波シール装置である。横シール機構3のフィルム検知機構は、本実施形態と同様に、超音波発信器の周波数などの出力値の変動を検出することによって、一対のシールジョー31によって筒状フィルムFmが挟まれているか否かを検知する。また、横シール機構3は、本実施形態の第2フィルム検知センサ52に相当する他のフィルム検知機構をさらに有してもよい。
本実施形態に係る製袋包装機100では、第2フィルム検知センサ52として光電センサが用いられるが、他の種類のセンサが用いられてもよい。例えば、第2フィルム検知センサ52として超音波センサが用いられてもよい。
