Description

【０００１】
【発明の属する技術分野】
本発明は、フィルム包装材で農作物等の物品を包装する包装装置に関する。
【０００２】
【従来の技術】
従来、この種の包装装置としては、例えば、フィルム包装材を保持する一つの包装材保持手段を設けるとともに、この一つの包装材保持手段に対して往復移動可能な包装材引出し手段を設け、かつ、この包装材引出し手段にて引き出されたフィルム包装材で物品を包装する一つの包装手段を前記フィルム包装材の引出し位置の下方に配設した構成の包装装置が知られている。
【０００３】
【発明が解決しようとする課題】
しかしながら、上記従来の包装装置では、一つの包装手段が一つの包装材保持手段からのフィルム包装材で、被包装対象物である物品を包装するので、作業効率が悪く、また、作業効率の向上のためにこの包装装置を複数台設置するのでは、コストがかかる問題を有している。
【０００４】
本発明は、このような点に鑑みなされたもので、作業効率を向上でき、コスト削減を図ることができる包装装置を提供することを目的とする。
【０００５】
【課題を解決するための手段】
請求項１記載の包装装置は、互いに離間対向して配設され、フィルム包装材を保持する対をなす包装材保持手段と、この対をなす包装材保持手段間に往復移動可能に配設され、前記各包装材保持手段に対する往復移動によりこの各包装材保持手段からフィルム包装材を引き出す包装材引出し手段と、前記対をなす包装材保持手段に対応して前記フィルム包装材の引出し位置に対向して配設され、前記包装材引出し手段にて引き出されたフィルム包装材で物品を包装する対をなす包装手段と、駆動力を出力して前記包装材引出し手段を往復移動させる引出し用駆動部と、前記包装材引出し手段を前記引出し用駆動部からの駆動力で一方の包装材保持手段に対して往復移動させることにより各包装材保持手段間の中央位置より一方の包装材保持手段側の一方寄り基準位置から各包装材保持手段間の中央位置より他方の包装材保持手段側の他方寄り基準位置まで移動させてこの一方の包装材保持手段からフィルム包装材を引き出させた後、他方の包装材保持手段に対して往復移動させることにより前記他方寄り基準位置から前記一方寄り基準位置まで移動させてこの他方の包装材保持手段からフィルム包装材を引き出させる制御手段とを具備したものである。
【０００６】
そして、包装材引出し手段が各包装材保持手段からフィルム包装材を引き出し、この対をなす包装材保持手段に対応して対をなす包装手段が各包装材保持手段からのフィルム包装材で物品を包装するので、従来の包装材保持手段および包装手段をそれぞれ一つ備えた構成のものに比べて、作業効率が向上する。また、包装材引出し手段が、各包装材保持手段に対する往復移動によりこの各包装材保持手段からフィルム包装材を引き出すので、各包装材保持手段に対応する複数の包装材引出し手段が必要でなく、従来の構成のものを対をなすように複数台設置する場合に比べて、コスト削減が図られる。さらに、制御手段が、包装材引出し手段を引出し用駆動部からの駆動力で一方の包装材保持手段に対して往復移動させることにより各包装材保持手段間の中央位置より一方の包装材保持手段側の一方寄り基準位置から各包装材保持手段間の中央位置より他方の包装材保持手段側の他方寄り基準位置まで移動させてこの一方の包装材保持手段からフィルム包装材を引き出させた後、他方の包装材保持手段に対して往復移動させることにより他方寄り基準位置から一方寄り基準位置まで移動させてこの他方の包装材保持手段からフィルム包装材を引き出させるので、各包装材保持手段間の中央位置を包装材引出し手段の基準位置とする構成のものに比べて、必要とされる引出し位置を確保しつつ各包装材保持手段間の離間距離を小さくでき、装置全体を小型にできる。
【０００７】
請求項２記載の包装装置は、互いに離間対向して配設され、フィルム包装材を保持する対をなす包装材保持手段と、この対をなす包装材保持手段間に往復移動可能に配設され、前記各包装材保持手段に対する往復移動によりこの各包装材保持手段からフィルム包装材を引き出す包装材引出し手段と、前記対をなす包装材保持手段に対応して前記フィルム包装材の引出し位置に対向して配設され、前記包装材引出し手段にて引き出されたフィルム包装材で物品を包装する対をなす包装手段と、駆動力を出力して前記包装材引出し手段を往復移動させる引出し用駆動部と、操作部の一回の操作により、前記包装材引出し手段を前記引出し用駆動部からの駆動力で前記各包装材保持手段間の中央位置の基準位置から一方の包装材保持手段に対して往復移動させてこの一方の包装材保持手段からフィルム包装材を引き出させた後、前記基準位置から他方の包装材保持手段に対して往復移動させてこの他方の包装材保持手段からフィルム包装材を引き出させる制御手段とを具備したものである。
【０００８】
そして、包装材引出し手段が各包装材保持手段からフィルム包装材を引き出し、この対をなす包装材保持手段に対応して対をなす包装手段が各包装材保持手段からのフィルム包装材で物品を包装するので、従来の包装材保持手段および包装手段をそれぞれ一つ備えた構成のものに比べて、作業効率が向上する。また、包装材引出し手段が、各包装材保持手段に対する往復移動によりこの各包装材保持手段からフィルム包装材を引き出すので、各包装材保持手段に対応する複数の包装材引出し手段が必要でなく、従来の構成のものを対をなすように複数台設置する場合に比べて、コスト削減が図られる。さらに、制御手段が、操作部の一回の操作により、包装材引出し手段を引出し用駆動部からの駆動力で各包装材保持手段間の中央位置の基準位置から一方の包装材保持手段に対して往復移動させてこの一方の包装材保持手段からフィルム包装材を引き出させた後、その基準位置から他方の包装材保持手段に対して往復移動させてこの他方の包装材保持手段からフィルム包装材を引き出させるので、各包装手段に応じて操作部を複数回操作しなければならない構成のものに比べて、操作性が向上する。
【０００９】
請求項３記載の包装装置は、請求項１または２記載の包装装置において、包装材保持手段は、複数対をなすように並設され、包装材引出し手段は、前記複数対をなす包装材保持手段間に往復移動可能に配設され、包装手段は、前記複数対をなす包装材保持手段に対応して複数対をなすように並設されているものである。
【００１０】
そして、包装材引出し手段が、各包装材保持手段からフィルム包装材を引き出し、この複数対をなす包装材保持手段に対応して複数対をなす包装手段が各包装材保持手段からのフィルム包装材で物品を包装するので、作業効率がより一層向上する。
【００１１】
【発明の実施の形態】
以下、本発明の包装装置の一実施の形態の構成を図面を参照して説明する。
【００１２】
図１および図２において、１は装置本体で、この装置本体１は、左右方向に長辺方向を有する外形略直方体形状に形成され、この装置本体１の上部の前側には操作部２が配設され、この操作部２には複数の押しボタン3a，3b，3cが互いに間隔をおいて並設されている。
【００１３】
また、この装置本体１の上部の左右両端にはフィルム包装材Ｆを保持する対をなす例えば一対の包装材保持手段5a，5bが互いに離間対向して配設され、この対をなす包装材保持手段5a，5b間には一つの包装材引出し手段６が前記装置本体１の左右方向に沿って往復移動可能に配設されている。
【００１４】
さらに、この装置本体１の上部の左右両端近傍には前記対をなす包装材保持手段5a，5bに対応して対をなす例えば一対の包装材切断手段7a，7bが互いに離間対向して配設され、この各包装材切断手段7a，7bにて所定寸法に切断されたフィルム包装材Ｆは、板状の包装材載置体９の上面部に形成された二箇所の載置面部9a上の引出し領域である引出し位置に載置される。
【００１５】
また、この包装材載置体９の載置面部9aの引出し位置には上下に貫通した物品供給口11がそれぞれ形成されているとともに、これら二箇所の引出し位置の下方には対をなす例えば一対の包装手段10a ，10b が、前記対をなす包装材保持手段5a，5bに対応して配設されている。
【００１６】
そして、前記包装材載置体９の物品供給口11に例えば農作物等の物品Ａが供給されると、この供給された物品Ａは、前記各包装手段10a ，10bによって前記各包装材保持手段5a，5bからのフィルム包装材Ｆで全体が被覆された状態に包装され、この包装済みの物品Ａは図示しない物品排出口から前記装置本体１の外部に排出される。なお、この装置本体１の底面部1cには複数の車輪13が取り付けられている。
【００１７】
前記包装材保持手段5a，5bは、ともに互いに離間対向した円筒形状の一対の支持ローラ21を有し、この各支持ローラ21は前記装置本体１の前後の側面部1a間に水平状に橋架された支軸22に嵌装され、自由回転可能となっている。
【００１８】
そして、この各支持ローラ21上に、円筒形状に巻かれたフィルム包装材Ｆが、巻き戻し可能に保持されている。なお、このフィルム包装材Ｆは例えば、合成樹脂等にて可撓性を有する透明なシート状に形成されたもので、幅方向の一端縁部には例えば色を付けた被検知部Ｆ1 が長さ方向に等間隔をおいて形成されている。
【００１９】
前記包装材引出し手段６は、前記各包装材保持手段5a，5b間の中央位置より一方の包装材保持手段5a側の一方寄り基準位置Ｘおよび他方の包装材保持手段5b側の他方寄り基準位置Ｙを基準位置として、前記各包装材保持手段5a，5bに対して往復移動することによって、この各包装材保持手段5a，5bからフィルム包装材Ｆを引き出すものである。なお、例えば、図２で明らかなように、この包装材引出し手段６が一方寄り基準位置Ｘに位置した状態では、この包装材引出し手段６は前記一方の包装手段10a 側の物品供給口11の近傍位置に位置し、一方の包装材保持手段5a側の引出し位置の上方に位置している。
【００２０】
そして、この包装材引出し手段６は、細長形状の引出し可動体26を有し、この引出し可動体26は前記装置本体１の前後の側面部1a間に橋架された状態に配設されている。
【００２１】
この引出し可動体26の上側には、フィルム包装材Ｆの先端縁部を挟持する挟持体27がこの引出し可動体26と一体的に移動するように取り付けられ、この挟持体27は前記引出し可動体26の上面に固定された下側挟持部材28を有するとともにこの下側挟持部材28に対して接離する上側挟持部材29を有している。
【００２２】
この下側挟持部材28は、例えば、前記引出し可動体26の長辺方向に沿って互いに間隔をおいて固定された複数の細長状の矩形板状片28a にて構成され、この各矩形板状片28a の長辺方向の両端部には先端側に向って下方向に傾斜した傾斜面状の傾斜ガイド体30が取り付けられている。
【００２３】
一方、前記上側挟持部材29は、例えば、短辺方向の中間部で断面コ字形状に屈曲された矩形板状に形成されたもので、前記引出し可動体26に立設された支柱31および第１のシリンダ装置32にて支持され、この第１のシリンダ装置32のロッド33の進退によって昇降する。なお、この上側挟持部材29の短辺方向の両端部にはフィルム包装材Ｆを介して前記下側挟持部材28の上面に圧接する圧接部34が形成されている。
【００２４】
また、この引出し可動体26の両端部には無端体連結部35が形成され、この各無端体連結部35がチェーン等の無端体36にそれぞれ連結固定されている。そして、この両無端体36は、原動回転体37と複数の従動回転体38，39とに掛け渡され、この原動回転体37がモータ等の引出し用駆動部40からの駆動力を受けて回転駆動するとこの両無端体36が所定方向に向って走行し、前記引出し可動体26が移動し、前記挟持体27が前記各包装材保持手段5a，5bからフィルム包装材Ｆを挟持しながら引き出す。
【００２５】
前記包装材切断手段7a，7bは、ともに前記包装材引出し手段６にて引き出されたフィルム包装材Ｆを所定位置で切断するもので、細長形状の取付けフレーム41を有し、この取付けフレーム41は前記装置本体１の前後の側面部1a間に橋架され、前記装置本体１の左右方向への移動により位置調節可能となっている。
【００２６】
この取付けフレーム41の下側には第２のシリンダ装置42のロッド43の進退によって昇降する昇降体45が取り付けられ、この昇降体45にはカッタ46が固定されているとともにこのカッタ46の両側方に棒状の複数の押え部材47が整列した状態で上下動自在に取り付けられている。
【００２７】
この各押え部材47は、前記カッタ46によるフィルム包装材Ｆの切断時に、このカッタ46でフィルム包装材Ｆを所定位置で確実に切断できるように、ばね48からの付勢力を受けてこのフィルム包装材Ｆを適切な力で押えるものである。なお、前記包装材載置体９にはこのカッタ46を挿入可能な溝部50が形成されている。
【００２８】
さらに、この包装材切断手段7a，7bの近傍位置には、各包装材切断手段7a，7bに対応して対をなす例えば一対の引出し長さ検知センサ51a ，51b が配設されている。
【００２９】
この一方の引出し長さ検知センサ51a は、前記装置本体１の前側の側面部1aに固定されたセンサ取付け部材52の先端部に取り付けられ、この一方の引出し長さ検知センサ51a が前記一方の包装材保持手段5aから引き出されたフィルム包装材Ｆの被検知部Ｆ1 を検知し、後述の制御手段110 に電気信号を出力する。また、他方の引出し長さ検知センサ51b は、前記装置本体１の後側の側面部1aに固定されたセンサ取付け部材52の先端部に取り付けられ、この他方の引出し長さ検知センサ51b が前記他方の包装材保持手段5bから引き出されたフィルム包装材Ｆの被検知部Ｆ1を検知し、同様に後述の制御手段110 に電気信号を出力する。
【００３０】
前記包装手段10a ，10b は、前記物品供給口11に向けて供給された物品Ａをフィルム包装材Ｆとともに受け取りこの受け取った物品Ａを移送する受取り移送部61a ，61b を備えるとともに、物品Ａの頂部近傍でフィルム包装材Ｆを絞り込みこのフィルム包装材Ｆで物品Ａを包装する絞込み部62a ，62b を備えている。なお、前記装置本体１の左側に位置する一方の受取り移送部61a と右側に位置する他方の受取り移送部61b とは左右対称の構造となっており、また、前記装置本体１の左側に位置する一方の絞込み部62a と右側に位置する他方の絞込み部62b とは、同様に左右対称の構造となっている。
【００３１】
前記受取り移送部61a ，61b は、ともに、上下に離間対向して対をなす杆保持体65を有し、この対をなす杆保持体65は前記装置本体１内の支持基板部1bの下面と前記装置本体１の底面部1cの上面とにそれぞれ固定されている。この各杆保持体65間には案内杆66が立設保持され、この案内杆66は物品受体67の挿通孔69に摺動可能に挿通されている。
【００３２】
また、この物品受体67の連結部68がチェーン等の無端体70に連結固定され、この無端体70は上下に離間対向した原動回転体71および従動回転体72に掛け渡されている。そして、この原動回転体71がモータ等の受体用駆動部73からの駆動力を受けて回転駆動すると、前記無端体70が所定方向に向って走行し、前記物品受体67が前記案内杆66にて案内されながら昇降する。
【００３３】
さらに、この物品受体67の上端部には、例えばおわん状の受取り部75が形成され、この受取り部75には矩形状の切欠き部76が形成されている。そして、この切欠き部76に押出し体78の上端側が挿通されると、この押出し体78の傾斜面状の押出面部79によって前記受取り部75内の包装済みの物品Ａが押し出され、この押し出された物品Ａが先端側が下方向に向って傾斜した傾斜状のシュート80を通って図示しない物品排出口から前記装置本体１の後方に排出される。
【００３４】
前記絞込み部62a ，62b は、図３および図４に示すように、ともに、互いに離間対向した支持フレーム81を有し、この各支持フレーム81は前記装置本体１内の支持基板部1bの上面に固定され、この各支持フレーム81の両端部間にはガイドロッド82が橋架されている。
【００３５】
そして、このガイドロッド82によって、第１絞込みスライド体84が前記物品供給口11の下方位置に対して進退できるようにスライド自在に保持され、かつ、第２絞込みスライド体85が前記第１絞込みスライド体84より上方において前記物品供給口11の下方位置に対して進退できるようにスライド自在に保持されている。この第１絞込みスライド体84と第２絞込みスライド体85とは高さ位置が異なり、互いに上下に重合可能となっている。
【００３６】
この第１絞込みスライド体84は、板状部材にて平面視略矩形状に形成され、長辺方向の両端部下面にはガイド部87が下方に向って突出形成され、このガイド部87の図示しない挿通孔に前記ガイドロッド82が摺動可能に挿通されている。また、この第１絞込みスライド体84の長辺方向の一端側にはラック部88が短辺方向に沿って形成されている。
【００３７】
さらに、この第１絞込みスライド体84の長辺方向の一端部にはロッド連結部89が形成され、このロッド連結部89に第３のシリンダ装置90のロッド91が連結固定されている。
【００３８】
また、この第１絞込みスライド体84の一側中央部には略半円形状の作用凹部93が略半円形状に形成され、他側中央部にはアーム取付け部94が形成されている。この第１絞込みスライド体84の下面にはヒータ95および包装材保持体96がそれぞれ取り付けられている。
【００３９】
一方、前記第２絞込みスライド体85は、板状部材にて平面視略矩形状に形成され、長辺方向の両端部下面にはガイド部97が下方に向って突出形成され、このガイド部97の図示しない挿通孔に前記ガイドロッド82が摺動可能に挿通されている。また、この第２絞込みスライド体85の長辺方向の一端下側には前記第１絞込みスライド体84のラック部88に上下に離間対向した状態でラック部98が短辺方向に沿って形成され、両ラック部88，98にはピンオン99が噛み合わされ、このピンオン99はピンオン支持部材100 にて回転可能に支持されている。
【００４０】
また、この第２絞込みスライド体85の一側中央部には、前記第１絞込みスライド体84と同様に、略半円形状の作用凹部93が略半円形状に形成され、さらに、この第２絞込みスライド体85の下面にもヒータ95および包装材保持体96がそれぞれ取り付けられている。
【００４１】
そして、前記第３のシリンダ装置90が作動して前記ロッド91が進出すると、前記両ラック部88，98およびピンオン99を介して前記第１絞込みスライド体84および第２絞込みスライド体85が互いに異なる方向に所定位置までスライド移動し、前記作用凹部93にてフィルム包装材Ｆが前記装置本体１の前後方向から絞り込まれ、この絞り込まれたフィルム包装材Ｆがばね92にて付勢された状態にある前記包装材保持体96にて保持され、前記ヒータ95にてヒートシールされかつそのシール部分より上側部分が溶断除去される。
【００４２】
一方、図３において、101 は一対の絞込みアーム体で、この各絞込みアーム体101 は前記第１絞込みスライド体84のアーム取付け部94に回動支軸部102 を中心として回動可能に取り付けられている。
【００４３】
この各絞込みアーム体101 は、板状部材にて平面視略へ字形状に形成され、基端部にはガイドローラ103 が回転可能に取り付けられ、各ガイドローラ103 はばね104 にて互いに接近する方向に付勢され、ローラ案内板105 の両側縁の傾斜状の作用面部106 に押し付けられている。なお、このローラ案内板105 は前記装置本体１内の支持基板部1bの上面に固定されている。
【００４４】
そして、前記各ガイドローラ103 が前記第１絞込みスライド体84の移動に伴って前記ローラ案内板105 の作用面部106 にて図３中の矢印のように案内されると、前記各絞込みアーム体101 の先端側が互いに接近する方向に移動し、この各絞込みアーム体101 の先端部にてフィルム包装材Ｆが前記装置本体１の左右方向から絞り込まれる。
【００４５】
また、図１において、110 は制御手段で、この制御手段110 には、前記操作部２、前記引出し用駆動部40、前記引出し長さ検知センサ51a ，51b 、前記受体用駆動部73、第１ないし第３のシリンダ装置32，42，90等が電気的に接続されている。そして、この制御手段110 は、作業者による前記操作部２の押圧操作、或いは前記引出し長さ検知センサ51a ，51b による検知等に基づいて、前記引出し用駆動部40、前記受体用駆動部73等を制御するものである。
【００４６】
次に、上記一実施の形態の動作を図面を参照して説明する。
【００４７】
図５(a) ないし(c) は包装装置の動作を説明するための説明図であり、図６は包装装置のタイムチャート図である。
【００４８】
図５(a) に示すように、包装材引出し手段６が、包装材載置体９上の一方寄り基準位置Ｘに位置した状態にあり、かつ、所定寸法に切断されたフィルム包装材Ｆが、包装材載置体９上の引出し位置に載置され、他方の包装手段10b 側の物品供給口11を閉塞した状態にある場合に、例えば作業者が物品Ａを上方からその物品供給口11に供給し、その後、操作部２の押しボタン3a，3cを同時に一回押圧操作すると、制御手段110 が、その包装材引出し手段６を引出し用駆動部40からの駆動力で一方の包装材保持手段5aに対して往復移動させることにより一方寄り基準位置Ｘから他方寄り基準位置Ｙまで移動させて一方の包装材保持手段5aからフィルム包装材Ｆを引き出させるとともに、他方の包装手段10b を作動させて物品Ａを包装させる。
【００４９】
すなわち、制御手段110 の制御に基づいて、包装材引出し手段６が、一方寄り基準位置Ｘから一方の包装材保持手段5aに向って所定位置まで移動すると、第１のシリンダ装置32が作動してロッド33が後退し、このロッド33の後退に伴って引出し可動体26の挟持体27がフィルム包装材Ｆの先端縁部を挟持する。
【００５０】
そして、この挟持体27がフィルム包装材Ｆの先端縁部を挟持すると、今度は、包装材引出し手段６が、一方の包装材保持手段5aから離反する方向に向って移動を開始し、この包装材引出し手段６の移動に伴ってフィルム包装材Ｆが一方の包装材保持手段5aから引き出される。
【００５１】
この引出し途中において、一方の引出し長さ検知センサ51a が、引出し中のフィルム包装材Ｆの被検知部Ｆ1 を検知すると、引出し用駆動部40が停止し、包装材引出し手段６が他方寄り基準位置Ｙで停止する。
【００５２】
そして、この包装材引出し手段６が他方寄り基準位置Ｙで停止すると、第２のシリンダ装置42が作動してロッド43が進出し、このロッド43の進出に伴って昇降体45が下降して、フィルム包装材Ｆがカッタ46にて所定位置で切断され、かつ、挟持体27による挟持状態が解除され、図５(b) に示す状態になる。
【００５３】
一方、図６に示すように、この包装材引出し手段６による一方の包装材保持手段5aからの引出しの開始と同時に、他方の包装手段10b による包装が開始される。
【００５４】
すなわち、他方の包装手段10b の受体用駆動部73が作動して、受取り移送部61b の物品受体67が図１に示す最上位高さ位置から所定高さ位置Ｈ1 まで下降し、この物品受体67の下降に伴ってフィルム包装材Ｆが物品供給口11内に引き込まれる。
【００５５】
そして、この物品受体67が所定高さ位置Ｈ1 に位置した状態で、今度は、第３のシリンダ装置90が作動してロッド91が進出し、このロッド91の進出に伴って絞込み部62b の第１絞込みスライド体84、第２絞込みスライド体85および絞込みアーム体101 の動きにより、フィルム包装材Ｆが、物品Ａの頂部近傍で全周方向から絞り込まれる。次いで、この絞り込まれたフィルム包装材Ｆが、包装材保持体96にて保持された状態で、ヒータ95にてヒートシールされ、そのシール部分より上側部分が溶断除去される。
【００５６】
その後、他方の包装手段10b の受体用駆動部73が作動して、さらに、受取り移送部61b の物品受体67が図１に示す所定高さ位置Ｈ1 から所定高さ位置Ｈ2 まで下降し、この物品受体67の下降に伴ってこの受取り部75の切欠き部76に押出し体78の上端側が挿通し、この押出し体78の傾斜面状の押出面部79によってその受取り部75内の包装済みの物品Ａが押し出され、この押し出された物品Ａがシュート80を通って図示しない物品排出口から前記装置本体１の後方に排出される。
【００５７】
その後、この受取り移送部61b の物品受体67は、受体用駆動部73の作動により、所定高さ位置Ｈ2 から最初の最上位高さ位置まで上昇する。なお、この他方の包装手段10b による包装が完了する前に、すでに、次の包装材引出し手段６による他方の包装材保持手段5bへの引出し動作が開始されている。
【００５８】
図５(b) に示すように、包装材引出し手段６が、包装材載置体９上の他方寄り基準位置Ｙに位置した状態にあり、かつ、所定寸法に切断されたフィルム包装材Ｆが、包装材載置体９上の引出し位置に載置され、一方の包装手段10a 側の物品供給口11を閉塞した状態にある場合に、作業者が物品Ａを上方からその物品供給口11に供給し、その後、操作部２の押しボタン3a，3cを同時に一回押圧操作すると、制御手段110 が、図５(c) に示されるようにその包装材引出し手段６を引出し用駆動部40からの駆動力で他方の包装材保持手段5bに対して往復移動させることにより他方寄り基準位置Ｙから一方寄り基準位置Ｘまで移動させて他方の包装材保持手段5bからフィルム包装材Ｆを引き出させるとともに、一方の包装手段10b を作動させて物品Ａを包装させる。
【００５９】
なお、この包装材引出し手段６による他方の包装材保持手段5bからの引出しの具体的動作は、一方の包装材保持手段5aからの引出し動作と同じであり、一方の包装手段10a による包装の具体的動作も他方の包装手段10b による包装動作と同じである。操作部２の押しボタン3bは緊急停止用の押しボタンである。
【００６０】
そして、上記動作の繰り返しにより、物品Ａの包装作業が交互に連続的に行われる。
【００６１】
このようにして、上記一実施の形態によれば、一つの包装材引出し手段６が各包装材保持手段5a，5bからフィルム包装材Ｆを引き出し、この対をなす包装材保持手段5a，5bに対応して対をなす包装手段10a ，10b がその各包装材保持手段5a，5bからのフィルム包装材Ｆで物品Ａを包装するので、従来の包装材保持手段および包装手段をそれぞれ一つ備えた構成のものに比べて、作業効率を向上できる。
【００６２】
また、この一つの包装材引出し手段６が、各包装材保持手段5a，5bに対する往復移動によりこの各包装材保持手段5a，5bからフィルム包装材Ｆを引き出すので、各包装材保持手段5a，5bに対応する複数の包装材引出し手段が必要でなく、従来の構成のものを対をなすように複数台設置する場合に比べて、コスト削減を図ることができ、しかも、設置スペースの確保も容易となる。
【００６３】
