Description

【０００１】
【発明の属する技術分野】
この発明は、例えば粉体や粒体、液体、半固形物、部品、食品等の充填物を容器内部に収容された袋体に充填する作業に用いられる充填包装装置に関する。
【０００２】
【従来の技術】
従来、上述の袋体を封鎖する装置としては、例えばダンボールケースの開口側周縁部（フラップ）に被覆された袋体の開口部を、直立保持機構を構成する各引っ掛け体で捲上げ及び起立して、第１保持体及び第２保持体、折曲げ体で保持した後、袋体内の空気を空気吸引パイプで吸い出し、袋体の両側面を一対の脱気板により押圧して、袋体内の空気を脱気する。且つ、脱気済み袋体の開口部を一対の把持ロッドで挟持した後、一対の把持ロッドを降下させながら回転して、袋体の開口部を巻回閉止する特許文献１の袋開口部封止装置がある。
【０００３】
【特許文献１】
特開昭５５−１３４００２号公報。
【０００４】
【発明が解決しようとする課題】
しかし、上述の袋開口部封止装置は、ダンボールケースの開口側周縁部に被覆された袋体の開口部を捲上げて巻回封止するものであるが、袋体の開口部を開口したまま、袋体内部に充填物を充填する充填工程から、その袋体の開口部を巻回封止する封止工程に供給するので、供給途中において、例えば水分や塵埃、ゴミ、病害虫等の異物が袋体内部に侵入しやすく、袋体に充填された金属製の部品及び物品に錆が発生するか、食品や原料が変質（腐敗を含む）する等して、充填物の品質及び鮮度が損なわれることがある。
【０００５】
この発明は上記問題に鑑み、容器内部に収容される袋体の口部を略扁平状態に閉塞したまま移動供給して、充填手段から供給される充填物を袋体内部に充填する直前に開口することにより、充填物以外の異物が袋体内部に侵入するのを防止でき、充填物の品質が損なわれず、高い信頼性が得られる充填包装装置の提供を目的とする。
【０００６】
【課題を解決するための手段】
この発明は、所定量の充填物を容器内部に収容された袋体に充填して包装する充填包装装置であって、上記容器内部に収容される大きさに形成した袋体の口部を略扁平状態に閉塞したまま保持して供給する受渡し手段と、上記受渡し手段から供給される袋体の口部を閉塞状態に保持し、該袋体の底部側を上記容器内部に収容して一緒に移動供給する移動手段と、上記移動手段から供給される袋体の口部を保持して上記充填物を充填する直前に開口する開口手段と、上記開口手段が開口保持する袋体内部に所定量の充填物を充填する充填手段と、上記充填物が所定量充填された袋体の口部を封鎖する封鎖手段とを備えた充填包装装置であることを特徴とする。
【０００７】
上述の袋体は、例えばガゼット折り状態や平折り状態等の扁平状態に折り畳まれた合成樹脂フィルム製（ビニール製）の袋、合成樹脂で被覆された紙製の袋等で構成される。また、容器は、例えば段ボール紙や厚紙、プラスチック、金属、木等の何れか一つ又は複合した材質で形成した箱体やケース、コンテナで構成される。また、受渡し手段は、例えば受渡し装置及びロール状に巻回するか、蛇行する状態に折り畳まれたフィルム原反及び袋体の口部を閉塞状態に保持して供給するチャックやアーム、吸着子、粘着体等で構成される。
【０００８】
また、移動手段は、例えば移動装置及び袋体の口部を閉塞状態に保持して供給するチャックやアーム、吸着子、粘着体等で構成される。また、開口手段は、例えば開口装置及び袋体の口部の四隅縁部を保持して開口するチャックやアーム、吸着子、粘着体等で構成される。また、充填手段は、例えば充填装置及び袋体の口部に挿入される充填口等で構成される。且つ、充填口は、例えば粉体や粒体、液体、半固形物、部品、食品等の充填物を供給する供給装置（図示省略）に接続されている。また、封鎖手段は、例えば封鎖装置及び袋体の口部の両側縁部を保持して巻回するチャックやアーム、吸着子、粘着体等で構成される。
【０００９】
つまり、容器内部に収容される大きさに形成された袋体の口部を受渡し手段で略扁平状態に閉塞したまま保持して、移動手段に受渡し供給する。受渡し手段から受渡し供給される袋体の口部を閉塞したまま移動手段で保持すると共に、袋体の底部側を容器内部に収容して開口装置に一緒に移動供給する。且つ、移動手段から受渡し供給される袋体の口部を閉塞したまま開口手段で保持して、充填開始直前に、袋体の口部を充填手段による充填が許容される大きさに開口保持した後、充填手段から供給される充填物（例えば粉体や粒体、液体、半固形物、部品、食品等）を袋体内部に所定量充填する。充填手段を袋体の口部から引き抜いた後、所定量の充填物が充填された袋体の口部を封鎖手段で閉塞（例えば巻回閉塞や重合閉塞等）して、次工程（例えば封函工程や出荷工程等）に供給する。なお、袋体の口部を閉鎖するとき、例えば袋体内部の空気を強制的に抜気及び脱気することもできる。
【００１０】
実施の形態として、上記受渡し手段前段に、扁平状態に折り畳まれた略筒状の包装体を長さ方向に連続して供給すると共に、該包装体を容器内部に敷設するのに適した一つの袋体に分離して上記受渡し手段に供給する分離供給手段を備えることができる。また、包装体は、例えばガゼット折り状態や平折り状態等の扁平状態に折り畳んだままロール状に巻回するか、蛇行する状態に折り畳まれた略筒状を有する合成樹脂製のフィルム原反で構成される。また、分離供給手段は、例えばフィルム原反を長さ方向に連続して供給する供給装置と、フィルム原反を幅方向に熱シールするか、接着剤で接着する交差シール装置及び分離シール装置と、フィルム原反を幅方向に切断する切断刃（カッタを含む）や回転刃、超音波裁断機、レーザ裁断機、ジェット裁断機等で構成される。且つ、フィルム原反を切断する代わりに、例えばミシン目や切れ目等を袋体の間に形成するか、テープや薄い部分、狭い部分、テープ等で袋体の間を分離可能に連結してもよい。
【００１１】
また、上記袋体及び容器を一緒に移動供給する移動手段の搬送路上に、上記開口手段及び充填手段を複数配設することができる。つまり、一方の開口手段及び充填手段による動作時間を利用して、次の袋体及び容器を他の開口手段及び充填手段に振分け供給する。また、上記袋体を、ガゼット折り状態に折り畳まれた袋体で構成することができる。且つ、袋体は、容器内部に収容及び敷設するのに適したサイズに形成されている。
【００１２】
【作用及び効果】
この発明によれば、容器内部に収容される袋体の口部を略扁平状態に閉塞したまま移動供給して、袋体の口部を、充填手段から供給される充填物を袋体内部に充填する直前に開口するので、移動途中において、例えば塵埃やゴミ、病害虫等の異物が袋体内部に侵入するのを防止でき、充填物の品質が損なわれず、高い信頼性が得られる。且つ、開口手段及び充填手段を移動手段の搬送路上に複数配設して、一方の開口手段及び充填手段による動作時間を利用して、次の袋体及び容器を他の開口手段及び充填装置手段に振分け供給するので、作業の能率アップ及び処理能力の向上を図ることができる。
【００１３】
【実施例】
この発明の一実施例を以下図面に基づいて詳述する。
【００１４】

【００１６】
前述の交差シール装置２０は、第１シール位置ａに供給されるフィルム原反ｆの上下面と対向して配設した上下一対の加熱ヘッド２１を、上下に配設した上下一対の押圧シリンダ２２によりフィルム原反ｆに対して押圧される方向に上下移動させ、フィルム原反ｆのシール部分（袋体Ｆ底部に相当する部分）を略クロス状態に熱シールする。

【００１８】
且つ、第２シール位置ｂに引き出されるフィルム原反ｆの右側面と対向して配設した切断刃３４（又は回転刃）及び押え部材３５を、同側に配設した進退シリンダ３４ａによりフィルム原反ｆに押圧される方向に前後移動させ、その進退シリンダ３４ａのロッド端部に水平架設したロッドレス型の往復シリンダ３４ｂにより、押え部材３５前面に突出した切断刃３４を幅方向に水平移動させ、押え部材３５，３９で押圧保持されたフィルム原反ｆのシール部分下位を幅方向に切断して、容器Ｂ内部に敷設するのに適したサイズの袋体Ｆに分離する。また、フィルム原反ｆの横幅と略対応する長尺の切断刃（図示省略）で切断してもよい。
【００１９】
且つ、第２シール位置ｂに引き出されるフィルム原反ｆの左側面と対向して配設した加熱ヘッド３８及び押え部材３９を、同側に配設した進退シリンダ３８ａによりフィルム原反ｆのシール部分に押圧される方向に前後移動させ、押え部材３５，３９で押圧保持されたフィルム原反ｆのシール部分（袋体Ｆ底部に相当する部分）を幅方向に熱シールする。
【００２０】
前述の受渡し装置４０は、上述の押圧体３１，３１により保持されたフィルム原反ｆの四隅縁部を略扁平状態に閉塞したまま挟持する左右一対の受渡しユニット４１，４１を昇降枠４２の遊端側両側部に取り付け、昇降枠４２の基端側を、第２シール位置ｂ上方と第１受渡し位置ｃ上方との間に斜設したレール４３に上下移動可能に取り付け、レール４３に沿って略平行に張架したチェーン４４を昇降枠４２に連結している。つまり、チェーン４４を、減速機付きモータ４５の駆動力により正逆回転して、受渡しユニット４１，４１を、押圧体３１，３１で保持されたフィルム原反ｆの四隅縁部を挟持する降下位置と、そのフィルム原反ｆの四隅縁部を後述する移動装置５０の左右一対の移動ユニット５１，５１に受渡し供給する上昇位置とに往復移動する。

【００２２】
且つ、受渡しユニット４１，４１から後述する移動ユニット５１，５１に受け渡された袋体Ｆが挿入許容されるサイズの箱体Ｂを載置する昇降台４６を、第１受渡し位置ｃ下部に配設し、昇降台４６の後端側を、同側に立設したレール４７及びロッドレス型の昇降シリンダ４８に上下動可能に取り付けている。つまり、降下位置（又は上昇位置）に配設した箱搬入コンベア４９から供給される製函済み箱体Ｂを昇降台４６に載置した後、昇降台４６を、昇降シリンダ４８により、移動ユニット５１，５１が略垂直に保持する袋体Ｆの底部と箱体ＢのフラップＢａ…との接触が回避される降下位置と、移動ユニット５１，５１が保持する袋体Ｆの底部又は袋体Ｆの略全体が箱体Ｂ内部に挿入される上昇位置とに、袋体Ｆ及び箱体Ｂのサイズに応じて上下動する。

【００３４】
図示実施例は上記の如く構成するものにして、以下、充填包装装置１による充填動作を説明する。
【００３５】
予め、図１、図２、図３にも示すように、分離シール装置３０の前後一対の押圧体３１，３１が保持するフィルム原反ｆの引出し側端部を略扁平状態に閉塞したまま、受渡し装置４０の左右一対の受渡しユニット４１，４１で保持した後、押圧体３１，３１を初期位置に復帰させて保持解除する。且つ、受渡しユニット４１，４１で保持したフィルム原反ｆを、容器Ｂ内部に敷設するのに適したサイズの袋体Ｆに分離可能な長さ引き出して、前後一対の押圧体３１，３１及び押え部材３５，３９で押圧保持する。一方、フィルム原反ｆのシール部分（袋体Ｆ底部に相当する部分）を、交差シール装置２０の上下一対の加熱ヘッド２１で略クロス状態に熱シールする。
【００３６】
次に、受渡しユニット４１，４１が保持するフィルム原反ｆを、第１受渡し位置ｃに引き出す途中又は引き出した後、押え部材３５，３９が押圧保持するフィルム原反ｆを切断刃３４で幅方向に切断し、加熱ヘッド３８で幅方向に熱シールして、容器Ｂ内部に敷設するのに適したサイズの袋体Ｆに分離すると共に、袋体Ｆの口部Ｆａを略扁平状態に閉塞したまま受渡しユニット４１，４１で保持して第１受渡し位置ｃに供給する。この後、切断刃３４及び加熱ヘッド３８、押え部材３５，３９を初期位置に復帰する。
【００３７】
且つ、図４、図６にも示すように、受渡しユニット４１，４１が保持する袋体Ｆの口部Ｆａを閉塞したまま、第１受渡し位置ｃに待機する移動装置５０の左右一対の移動ユニット５１，５１に受け渡し、箱搬入コンベア４９から供給される箱体Ｂを昇降台４６に載置して上昇させ、移動ユニット５１，５１が略垂直に保持する袋体Ｆを、箱体Ｂ内部に挿入（例えば袋体Ｆの底部が箱体Ｂ内部の底面に近接又は接触する状態）する。上述と同様にして、受渡しユニット４１，４１を第１受渡し位置ｃと第２シール位置ｂとに往復移動させ、フィルム原反ｆの引出し作業を継続する。
【００３８】
且つ、図５、図７にも示すように、左右一対の移動ユニット５１，５１が保持する袋体Ｆの口部Ｆａを閉塞したまま、箱移動コンベア５６に載置された箱体Ｂに挿入したまま第２受渡し位置ｄに搬送し、開口装置６０の左右一対の開口ユニット６１，６１に受け渡して充填位置ｅに移動すると共に、その袋体Ｆの口部Ｆａを、充填開始直前及び充填口７１の挿入直前において、充填装置７０の充填口７１が挿入許容される大きさに開口する。上述と同様にして、移動ユニット５１，５１を、第１受渡し位置ｃと第２受渡し位置ｄ，ｄとに往復移動させ、一方の開口装置６０及び充填装置７０による動作時間を利用して、袋体Ｆを箱体Ｂに挿入したまま他方の開口装置６０及び充填装置７０に振分け供給する。
【００３９】
次に、充填装置７０の充填口７１を、開口ユニット６１，６１が開口保持する袋体Ｆの口部Ｆａに挿入して充填物を充填すると共に、計量器６８が計量する充填物の充填量に応じて、袋体Ｆが挿入された箱体Ｂを徐々に又は段階的に降下させる。且つ、所定の充填量に達する直前に、充填口７１から吐出される充填物の量を減少させ、充填量を微調整して所定量充填する。
【００４０】
次に、図８、図９にも示すように、封鎖装置８０の左右一対の緊張棒８１ｂ，８１ｂを、開口ユニット６１，６１が開口する袋体Ｆの口部Ｆａに挿入して略扁平状態に緊張し、開口ユニット６１，６１による挟持を解除して初期位置に復帰させ、充填装置７０の充填口７１を、袋体Ｆの口部Ｆａから抜き取った後、袋体Ｆ内部の空気を略中空断面形状の緊張棒８１ｂ，８１ｂから強制的に抜気する。
【００４１】
続いて、左右一対の封鎖ユニット８１，８１で袋体Ｆの口部Ｆａの両側縁部を挟持し、緊張棒８１ｂ，８１ｂを袋体Ｆの口部Ｆａから抜き取った後、封鎖ユニット８１，８１を降下動作させながら回転して、袋体Ｆの口部Ｆａを巻回封鎖する。この後、封鎖ユニット８１，８１による挟持を解除して初期位置に復帰させる。上述と同様にして、充填物を、袋体Ｆに充填する作業を継続して行う。且つ、所定量の充填物を袋体Ｆに充填した後、図１に示すように、計量台６７から供給される充填済みの箱体Ｂを箱搬出コンベア８６で次工程（例えば封函工程、出荷工程等）に搬送する。
【００４２】
以上のように、箱体Ｂ内部に収容及び敷設される大きさに分離された袋体Ｆの口部Ｆａを略扁平状態に閉塞したまま受渡し手段４０と、移動手段５０と、開口装置６０とに受渡し供給し、袋体Ｆの口部Ｆａを、充填装置７０から供給される充填物を袋体Ｆ内部に充填する直前に開口するので、移動途中において、例えば塵埃やゴミ、病害虫等の異物が袋体Ｆ内部に侵入するのを防止でき、充填物の品質が損なわれず、高い信頼性が得られる。
【００４３】
且つ、移動装置５０の移動ユニット５１，５１を、第１受渡し位置ｃと第２受渡し位置ｄ，ｄとに往復移動させ、一方の開口装置６０及び充填装置７０による動作時間を利用して、次の袋体Ｆ及び箱体Ｂを他方の開口装置６０及び充填装置７０に振分け供給するので、作業の能率アップ及び処理能力の向上を図ることができる。
