Description

【０００１】
【発明の属する技術分野】
本発明は包装機の横シール装置に係り、さらに詳しくは、内容物が充填された筒状フィルムを一袋分に分離することができる包装機の横シール装置に関する。
【０００２】
【従来の技術】
筒状フィルムに内容物を充填する包装機は従来より実施されており、この種の包装機には、液状の内容物が充填された筒状フィルムを熱溶着して包装袋を成形するとともに包装袋に内容物を充填するための横シール装置が備えられている。
【０００３】
この包装機によれば、図９に示すように、一対の送りローラ１００、１００を矢印Ｒ１の方向に回転することで、内容物１０１が充填された筒状フィルム１０２を下方に送り、一対のしごきローラ１０３、１０３を矢印Ｓで示す方向に移動した後、矢印Ｒ２の方向に回転することで、内容物１０１が充填された筒状フィルム１０２をしごき、ここで、しごいた部分１０２ａは横シール装置１０５の位置まで下方に送られる。
【０００４】
しごいた部分１０２ａが横シール装置１０５まで送られると、一対の加圧熱シール部１０６，１０６が矢印Ａの方向に移動してしごいた部分１０２ａを挟持する。一対の加圧熱シール部１０６、１０６は電熱ヒータ１０７、１０７で所定温度まで加熱されているので、一対の加圧熱シール部１０６、１０６でしごいた部分１０２ａを挟持することでしごいた部分１０２ａを熱融着してシールすることができる。
しごいた部分１０２ａをシールした後、一対の加圧熱シール部１０６，１０６を開いて、シールした部分を冷却切断部１０８、１０８まで下方に送る。
【０００５】
シールした部分が冷却切断部１０８、１０８まで送られると、一対の冷却切断部１０８、１０８が矢印Ｂの方向に移動してシールした部分を挟持する。一対の冷却切断部１０８、１０８は冷却手段１０９、１０９で所定温度まで冷却されているので、一対の冷却切断部１０８、１０８でシールした部分を挟持することでシールした部分を冷却することができる。
【０００６】
さらに、左側の冷却切断部１０８には切断刃１１０が取り付けられているので、一対の冷却切断部１０８、１０８でシールした部分を挟持することで、シールした部分を冷却するとともに切断することができる。
この操作を順次繰り返すことにより、内容物１０１が充填された筒状フィルム１０２を一定間隔おいてシールし、かつシールした部分を切断することができるので、内容物１０１を所定量詰めた包装袋１１２を得ることができる。
【０００７】
【発明が解決しようとする課題】
ところで、従来の横シール装置１０５は、包装袋１１２に内容物１０１を充填する際に、一定量の内容物１０１を包装袋１１２に正確に充填するために、筒状フィルム１０２を下降させる際に、筒状フィルム１０２の下降量を一対の送りローラ１００、１００で正確に調整する必要がある。
【０００８】
しかしながら、筒状フィルム１０２の下降量を正確に調整するためには、一対の送りローラ１００、１００、一対のしごきローラ及び横シール装置を精度よく制御する必要がある。このため、一対の送りローラ、一対のしごきローラ及び横シール装置の調整に時間がかかり、生産性を高めることが難しいという問題があった。
【０００９】
加えて、筒状フィルム１０２の下降量を正確に調整するためには、一対の送りローラ１００、一対のしごきローラ１０３及び横シール装置１０５などの設備を高精度に構成する必要もある。しかしながら、設備を高精度に構成するためには、設備費が嵩むという問題があった。
【００１０】
この発明は、生産性を高めることができ、かつ設備費を抑えることができる包装機の横シール装置を提供して、上述の全ての問題点を解消しようとするものである。
【００１１】
【課題を解決するための手段】
本発明の上記目的を達成するために請求項１は、内容物が充填された筒状フィルムを一対のしごきローラで挟み込み、これらのしごきローラで筒状フィルムをしごくことにより内容物を一袋分に分離し、一対のローラでしごいたしごき部の上下端を挟持手段で挟持し、この上下端の間のしごき部を接着手段で接着し、この接着部を切断手段で切断する包装機の横シール装置において、この包装機の横シール装置は、前記挟持手段が、しごき部を確実に挟持するために十分な挟持圧をかける本挟持状態と、しごき部を軽く押さえるために軽い挟持圧をかける仮挟持状態とに切替え可能に構成され、前記挟持手段でしごき部を仮挟持状態に押さえた際に、挟持手段の下方に吊下された包装袋を収容することが可能な加圧タンクが備えられ、包装袋内を所定の内容量となるように内容物が包装袋の外に押し出される程度の圧力状態に調節しながら、この加圧タンク内を加圧することによりタンク内の包装袋に圧力をかけ、包装袋内の余分な内容物をしごき部を介して包装袋の外に押し出す定量加圧手段が備えられていることを特徴とする。
【００１２】
また本発明の請求項２は、内容物が充填された筒状フィルムを一対のしごきローラで挟み込み、これらのしごきローラで筒状フィルムをしごくことにより内容物を一袋分に分離し、一対のローラでしごいたしごき部の上下端を挟持手段で挟持し、この上下端の間のしごき部を接着手段で接着し、この接着部を切断手段で切断する包装機の横シール装置において、この包装機の横シール装置は、前記挟持手段が、しごき部を確実に挟持するために十分な挟持圧をかける本挟持状態と、しごき部を軽く押さえるために軽い挟持圧をかける仮挟持状態とに切替え可能に構成され、前記挟持手段でしごき部を仮挟持状態に押さえた際に、挟持手段の下方に吊下された包装袋を収容することが可能な加圧タンクが備えられ、包装袋内を所定の内容量となるように内容物が包装袋の外に押し出される程度の圧力状態に調節しながら、この加圧タンク内を加圧することによりタンク内の包装袋に圧力をかけ、包装袋内の余分な内容物をしごき部を介して包装袋の外に押し出す定量加圧手段が備えられ、この定量加圧手段で包装袋から押し出しされた余分な内容物を吸引ノズルで除去する除去手段が備えられていることを特徴とする。
【００１３】
上記した本発明に係る包装機の横シール装置は、挟持手段を本挟持状態と仮挟持状態とに切替え可能に構成した。このため、挟持手段でしごき部を仮挟持状態に押さえた際に、定量加圧手段で加圧タンク内を加圧して、加圧タンク内の包装袋に所定圧をかけることにより、包装袋内の余分な内容物をしごき部を介して包装袋の外に押し出すことができる。さらに請求項２では、除去手段を備えたので、包装袋から押し出された余分な内容物は除去されることとなった。この除去手段の例としては、吸引ノズルで吸い込むか、あるいは機械又は手で拭き取るか、さらには送風機で吹き飛ばす等の適宜の手段を採用することができる。
【００１４】
【発明の実施の形態】
以下添付図に基づいて本発明に係る包装機の横シール装置の一実施の形態を詳説する。
図１は本発明に係る包装機の横シール装置の断面図、図２は本発明に係る包装機の横シール装置の平面図、図３〜図８は本発明に係る包装機の横シール装置の作用１〜６の作用を説明した図である。
【００１５】
図１に示す包装機の横シール装置１０は、内容物１１が充填された筒状フィルム１２を一対のしごきローラ１３、１３で挟み込み、これらのしごきローラ１３、１３で筒状フィルム１２をしごくことにより内容物１１を一袋（包装袋）１５になるように分離し、一対のしごきローラ１３、１３でしごいたしごき部１６の上下端を挟持手段２０で挟持し、しごき部１６の中央を接着手段３０で接着し、この接着した部分を切断手段５０で切断するものである。
なお、一対のしごきローラ１３、１３の上方には一対の送りローラ１４、１４が備えられている。
ここで接着手段の例としては、熱で融着する熱融着の例とか、接着剤を使用する接着剤接着の例が挙げられ、フィルムの厚さ等の仕様によって最適のものを選択すれば十分である。
【００１６】
内容物１１の一例としては、液体状の内容物はもちろんのこと、それ以外に粉体状、流体状の内容物にも応用することができる。また、筒状フィルム１２としては、一例としてポリエチレンの単体フィルムや複合フィルム（ナイロンとポリエチレンとを合わせたフィルム）が該当する。
【００１７】

他の除去手段として、機械又は手による拭き取り、あるいは送風機による吹き飛ばし等の手段を採用することもできる。
【００３５】
なお、吸込口８２を一対のしごきローラ１３、１３と略同じ高さに設定することで、一対のしごきローラ１３、１３をしごき位置にセットした際に、吸込口８２を開放状態に保つことができ、かつ筒状フィルム１２内の内容物１１が下方に滴下することを防ぐことができる。
【００３６】
また本発明の図面では、シリコンチューブ２４を上下二段に設置した例を示したが、単体袋や連続体袋の何れにも対応できるようにするため、必要に応じてシリコンチューブ２４を上下一段構成に設置するようにすることも可能である。
【００３７】
つぎに、本発明に係る包装機の横シール装置１０の作用について図３〜図８に基づいて説明する。
図３に示すように、一対の送りローラ１４、１４を矢印Ａの方向に回転することで、内容物１１が充填された筒状フィルム１２を下方に送る。
【００３８】
図４に示すように、一対のしごきローラ１３、１３を矢印Ｂで示す方向に移動した後、一対の送りローラ１４、１４とともに一対のしごきローラ１３、１３を矢印Ｃの方向に回転することで、内容物１１が充填された筒状フィルム１２を下方に送りながらしごく。これにより、一袋分の内容物１１が筒状フィルム１２から分離される。
【００３９】
図５に示すように、包装袋１５の先端１５ａが加圧タンク内の位置決めセンサー６３まで到達すると、発光部６３ａから投光された光が遮られて受光部６３ｂに到達しなくなる。これにより、位置決めセンサー６３で包装袋１５の存在を検知して、一対の送りローラ１４、１４及び一対のしごきローラ１３、１３の回転を停止させる。
【００４０】
図６に示すように、移動手段４０のエアシリンダ４３、４３を操作して、挟持手段２０の密閉ボックス２１、２１を閉位置に移動する。このとき、接着手段３０の加圧バー３１、３１及び切断手段５０のカット刃５２、５２も同時に移動する。
つぎに、加圧手段２５のエア加圧部２８を操作して、シリコンチューブ２４、２４の中空部２４ａ、２４ａに軽い挟持圧をかける。これにより、しごき部１６の上下端をシリコンチューブ２４、２４で軽く押さえる。
【００４１】
ついで、定量加圧手段７０の真空用オンオフ弁７３をオンにして真空部７２を操作することで、タンク内空間６４を真空にする。
つづいて、加圧用オンオフ弁７６をオンにして加圧部７５を操作することで、タンク内空間６４を所定圧に加圧する。
【００４２】
タンク内空間６４を所定圧に加圧して、包装袋１５に外側から所定圧をかけることにより、包装袋１５内の余分な内容物１１をしごき部１６を介して包装袋１５の外に押し出す。これにより、包装袋１５に所定量の内容物１１を正確に充填することができる。
【００４３】
ここで、しごき部１６の上下端はシリコンチューブ２４、２４で軽く押さえられただけなので、包装袋１５の外に押し出された内容物１１は、しごき部１６内を上昇して除去手段８０の吸引ノズル８１等から吸い込まれて除去される。
このように、タンク内空間６４を所定圧に加圧することにより、包装袋１５内に所定量の内容物１１を時間をかけないで簡単に収納することができるので、生産性を高めることができる。
また、筒状フィルム１２の送り量を正確にするために設備を高精度に構成する必要がないので、設備費が嵩むことを抑えることができる。
【００４４】
図７に示すように、加圧手段２５のエア加圧部２８を操作して、シリコンチューブ２４、２４の中空部２４ａ、２４ａに十分な挟持圧をかけることで一対のシリコンチューブ２４、２４でしごき部１６を本挟持する。
【００４５】
つぎに、移動手段４０のエアシリンダ４３、４３を操作して、接着手段３０の加圧バー３１、３１を閉位置に移動することにより、加圧バー３１、３１でしごき部１６を挟持する。ついで、加熱冷却切替え手段３５の熱風源用オンオフ弁３９ａをオンとし、熱風源３７を操作することにより加圧バー３１、３１の凹部３２ａ、３２ａに熱風を流し、例えばしごき部１６を熱融着する。
【００４６】
つづいて、加熱冷却切替え手段３５の冷風源用オンオフ弁３９ｂをオンとし、冷風源３８を操作することにより加圧バー３１、３１の凹部３２ａ、３２ａに冷風を流し、熱融着した部分を冷却する。
つぎに、移動手段４０のエアシリンダ４３、４３を操作して、カット刃５２、５２を熱融着した部分に強く押し付ける。これにより、熱融着した部分をカット刃５２、５２で切断し、内容物１１を正確な定量で充填された包装袋１５を得ることができる。
【００４７】
図８に示すように、加圧タンク６０の加圧タンク蓋６２を開放する。つぎに、加圧手段２５のエア加圧部２８を操作して、シリコンチューブ２４、２４の中空部２４ａ、２４ａから挟持圧を解除するとともに、移動手段４０のエアシリンダ４３、４３を操作して、挟持手段２０の密閉ボックス２１、２１を開位置に移動する。
このとき、接着手段３０の加圧バー３１、３１及び切断手段５０のカット刃５２、５２も同時に開方向に移動する。よって、加圧タンク６０内の包装袋１５が下方に落下する。
【００４８】
この操作を順次繰り返すことにより、内容物１１が充填された筒状フィルム１２を一定間隔おいてシールし、かつシールした部分を切断することができるので、正確な定量の内容物１１を充填した包装袋１５を得ることができる。
【００４９】
なお、前記実施の形態では、移動手段４０にエアシリンダ４３を使用した例について説明したが、これに限らないで、薄いフイルムの場合には、移動手段４０のない固定でも良く、又は油圧シリンダ、クランク機構やラック・ピニオン機構を用いても良く、さらには単体袋フィルムの場合には、その接着に際し、溶着部のない接着剤接着とすることも可能である。
【００５０】
また、前記実施の形態では、筒状フィルム１２の素材としてポリエチレンの単一フィルムや複合フィルム（ナイロンとポリエチレンとを合わせたフィルム）に限らないで、種々のフィルムを使用することができる。
【００５１】
【発明の効果】
以上述べたように、請求項１による包装機の横シール装置によれば、挟持手段を本挟持状態と仮挟持状態とに切替え可能に構成した。このため、挟持手段でしごき部を仮挟持状態に押さえた際に、定量加圧手段で加圧タンク内を加圧して、加圧タンク内の包装袋に所定圧をかけることにより、包装袋内の余分な内容物をしごき部を介して包装袋の外に押し出すことができる。従って、包装袋内に所定量の内容物を時間をかけないで簡単に収納することができるので、生産性を高めることができる。
【００５２】
また、筒状フィルムの送り量を正確にするために設備を高精度に構成する必要がないので、設備費が嵩むことを抑えることができる。
加えて、除去手段を備えたので、包装袋から押し出した余分な内容物を、例えば吸引ノズル等から吸い込むことができる。除去された内容物は、状況によって再利用することもできる。
