【０００１】
【産業上の利用分野】
本発明は、包装フィルムをガセット付き角床袋形状に形成しつつ被包装物を包装する製袋充填包装が可能な縦形製袋充填包装機に関する。
【０００２】
【従来の技術】
従来、ガセットが付いた角床形の製袋充填包装袋は、図３に示すように、包装フィルムが筒状に折り曲げられるとともに、フィルム両端縁のフィルム内面同士を合わせて縦シールｇを施して包装筒とされ、縦シールｇが袋の裏面中央にくるように該包装筒の下部両側面を包装筒内方へ押し込めて下部ガセットｃが付けられ、袋の前後方向両側からボトム横シールｄが施され、袋内に被包装物が充填された後に、袋の上部両側面を袋内方へ押し込めて上部ガセットｅが付けられ、袋の上端にトップ横シールｆが施されてなるものであった。そして、図４に示すように、該製袋充填包装袋を製造する縦形製袋充填包装機は、製袋器１の案内作用により包装フィルムＦを製品落下充填筒２を包む筒状となるように曲成し、かつ製品落下充填筒２の前側で包装フィルムＦの両端縁のフィルム内面同士を合わせて縦ヒートシール装置３で挟圧して電熱することによって縦シールｇを施して包装筒Ｈを形成し、製品落下充填筒２の下方に垂下する包装筒Ｈ内に製品落下充填筒２を通して被包装物を充填し、製品落下充填筒２の下方に一対に設けられているガセット板４を製品落下充填筒２の下端より垂下されている両側に各二本の棒部材５，５の間に外方から突っ込むことにより、包装筒Ｈの両側にガセットを付け、包装筒Ｈの前記充填した被包装物の上をガセットが付いた状態に横ヒートシール・カット装置６で挟圧して電熱することによって二条の横シールｃ，ｄを施すとともに横シールｃ，ｄ間を切り離しカットするように構成されていた。
【０００３】
【発明が解決しようとする課題】
上記の従来の製袋充填包装袋は、縦シールが袋の裏面中央にくるので、形態上、袋に表裏が有ることが避けられない。したがって、包装フィルムの袋の表裏となる部分に別々の印刷をしなければならず、商品陳列上も袋包装体の表裏を考慮しなければならない。また、袋内に被包装物を充填したとき、袋の両側部にガセットを備えているので袋底面が角床形状になるが、袋の下部両側部が袋内の被包装物によって押されることで膨らんでしまい、角床袋の形状が悪くなっていた。
【０００４】
そこで本発明者は、図３に示す従来の製袋充填包装袋の欠点を解消し得るものとして、図２に示す形態の製袋充填包装袋を案出した。該製袋充填包装袋は、包装フィルムが筒状に折り曲げられるとともに、フィルム両端縁のフィルム内面同士を合わせて縦シールａが施され且つフィルム巾中央縦線よりフィルム内面同士を合わせて飾りの縦シールｂが施されて包装筒とされ、該包装筒の縦シールａと飾りの縦シールｂが包装筒下部内方へ押し込められ下部ガセットｃが付けられ、縦シールａと飾りの縦シールｂの対向方向と直交する方向からボトム横シールｄが施されて、袋内に被包装物を充填した後に該包装筒の縦シールａと飾りの縦シールｂが包装筒上部内方へ押し込められ上部ガセットｅが付けられ、トップ横シールｆを施されて形成されている。この製袋充填包装袋は、袋の両側部に縦シールａと飾りの縦シールｂが現れる形態を有している。
【０００５】
本願第一発明の目的は、図２に示す形態の製袋充填包装袋となるように製袋し得る縦形製袋充填包装機を提供することであり、また本願第二発明の目的は、上記本願第一発明の目的に加えて、製品充填筒の中程でブリッジが生じないとともに、フィルムの円筒曲成が製品充填筒に密着する性質があるナイロン系やポリエステル系の包装フィルムであっても飾りの縦シールを良好に形成することができ、また厚い包装フィルムやアルミニウムの薄膜をベースとして積層した包装フィルムであっても、製袋器の頂上部のところで折り返される際にフィルム巾方向に波が生じて傷になるということがないように製袋し得る縦形製袋充填包装機を提供することである。
【０００６】
【課題を解決するための手段】
上記の課題を解決するため、本願第一発明による縦形製袋充填包装機は、包装フィルムを製品充填筒を包む筒状となるように案内曲成する製袋器、前記製品充填筒の前側で前記包装フィルムの両端縁のフィルム内面同士を合わせて縦シールを施し前記包装フィルムを包装筒に形成する縦ヒートシール装置、前記製品充填筒の下端両側より各側でそれぞれ二本が垂下されている棒部材、前記製品充填筒の下方に設けられておりそれぞれ前記各二本の棒部材の間に外方から突っ込むことにより前記包装筒の両側にガセットを付ける一対のガセット板、及び前記製品充填筒から垂下する前記包装筒内に前記製品充填筒を通して充填された被包装物の上方の前記包装筒をガセットが付いた状態で二条の横シールを施す横ヒートシール装置を備えている縦形製袋充填包装機において、前記製品充填筒の後側上部に、フィルム巾中央部を折り線としてフィルム内面同士が折合わされるフィルム巾中央部折合せ部分を形成するリブが設けられており、前記製品充填筒の後側で且つ前記リブの下側に、前記フィルム巾中央部折合せ部分に飾りの縦シールを施す後側縦ヒートシール装置が設けられており、前記棒部材の各二本は前記製品充填筒の下端の前側と後側で垂下しており、前記ガセット板は、前記製品充填筒の前側下方と後側下方に一対に設けられていて、前記各側の二本の棒部材の間に外方から突っ込んで前後一対の縦シールをそれぞれ各側の前記ガセットと一致させて前記包装筒内方に押し込み動作し、更に前記横ヒートシール装置は、四本の前記棒部材よりも所要下方において左右方向に閉じて前記横シールを施すことを特徴としている。
【０００７】
また、上記の課題を解決するため、本願第二発明による縦形製袋充填包装機は、包装フィルムを製品充填筒を包む筒状となるように案内曲成する製袋器、前記製品充填筒の前側で前記包装フィルムの両端縁のフィルム内面同士を合わせて縦シールを施し前記包装フィルムを包装筒に形成する縦ヒートシール装置、前記製品充填筒の下端両側より各側でそれぞれ二本が垂下されている棒部材、前記製品充填筒の下方に設けられておりそれぞれ前記各二本の棒部材の間に外方から突っ込むことにより前記包装筒の両側にガセットを付ける一対のガセット板、及び前記製品充填筒から垂下する前記包装筒内に前記製品充填筒を通して充填された被包装物の上方の前記包装筒をガセットが付いた状態で二条の横シールを施す横ヒートシール装置を備えている縦形製袋充填包装機において、前記製品充填筒は、外形が実質的に円形に形成されていて前記製袋器との間に前記包装フィルムを通す環状隙間を確保する上半部、後面側に上端から下端までにわたって形成された偏平面部、及び前記偏平面部の上部の巾中央部に付設されており前記包装フィルムのフィルム巾中央部を折り線としてフィルム内面同士が折合わされるフィルム巾中央部折合せ部分を形成するリブを備えており、前記偏平面部と前記リブとに対応して、前記包装フィルムを前記偏平面部と前記リブとに密着するように曲成ガイドするフィルムガイド板が対設されており、前記製品充填筒の後側で且つ前記リブの下側に、前記フィルム巾中央部折合せ部分に飾りの縦シールを施す後側縦ヒートシール装置が設けられており、前記棒部材の各二本は前記製品充填筒の下端の前側と後側で垂下しており、前記ガセット板は、前記製品充填筒の前側下方と後側下方に一対に設けられていて、前記各側の二本の棒部材の間に外方から突っ込んで前後一対の縦シールをそれぞれ各側の前記ガセットと一致させて前記包装筒内方に押し込み動作し、更に前記横ヒートシール装置は、四本の前記棒部材よりも所要下方において左右方向に閉じて前記横シールを施すことを特徴としている。
【０００８】
【作用】
本願第一発明による縦形製袋充填包装機の作用を説明する。包装フィルムの両端縁が製品充填筒の前側で内面同士を合わされ、縦ヒートシール装置はフィルム両端縁に縦シールを施す。また、包装フィルムのフィルム巾中央部分は、製品充填筒に密着するとともにリブを密着迂回するように曲成される。包装フィルムのリブを密着迂回する部分は、リブの下側に移送されたところでフィルム内面同士が自然に折り合い、後側縦ヒートシール装置はフィルム内面同士が折り合った部分に飾りの縦シールを施す。こうして、製品充填筒の下方の前側に縦シール、後側に飾りの縦シールが施された包装筒が垂下する。該包装筒を一対のガセット板が、両側の各二本の棒部材の間において、折込み方向を各縦シールと一致させて外方から突っ込んで両側にガセットを付ける。そこで、製品落下充填筒を通して被包装物を充填して横ヒートシール装置で包装筒の被包装物の上下を横シールを施すと、形態上袋の表裏がなく角床袋の形状が良好に維持できる袋の製袋充填包装ができる。
【０００９】
本願第二発明による縦形製袋充填包装機の作用を説明する。製品充填筒の製袋器で取り巻かれている部分の上半部の外形が実質的に円形に形成され製袋器との間に包装フィルムを通す環状隙間が確保されているので、包装フィルムは、製品充填筒に密着して円筒に曲成される種類と、製品充填筒から離れて製袋器の円筒部に密着して円筒に曲成される種類のいずれでも、折り径が同一になるように円筒状に曲成され、製品充填筒の偏平面部に移送されると、偏平面部に対応するフィルム部分（フィルム巾中央部）に飾りの縦シールを形成するのに利用できる余剰寸法代が生じる。また製品充填筒と製袋器との間の隙間が小さいから、厚い包装フィルムやアルミニウムの薄膜をベースとして積層した包装フィルムであっても、製袋器の頂上部のところで折り返される際にフィルム巾方向に波（フィルムの暴れ）が生じることが防止され、皺や傷が生じないように製品充填筒を包む綺麗な筒状に曲成される。包装フィルムの両端縁が製品充填筒の前側で内面同士を合わされ、縦ヒートシール装置はフィルム両端縁に縦シールを施す。また、包装フィルムの偏平面部に対応する巾中央部分は、製品充填筒の偏平面部側に対設されているフィルムガイド板のガイド作用により偏平面部に密着するとともにリブを密着迂回するように曲成される。包装フィルムのリブを密着迂回する余剰寸法代部分は、リブの下側に移送されたところでフィルム内面同士が自然に折り合い、飾りの縦シール用縦ヒートシール装置はフィルム内面同士が折り合った部分に飾りの縦シールを施す。こうして、製品充填筒の下方に前側に縦シール，後側に飾りの縦シールが施された包装筒が垂下する。一対のガセット板は、両側の各二本の棒部材の間において、折り込み方向を各縦シールに一致させて、外方から該包装筒に突っ込んで両側にガセットを付ける。そこで、製品充填筒を通して被包装物を充填し、横ヒートシール装置で包装筒の被包装物の上下の位置で横シールを施すと、角床袋の形状が良好に維持できる袋の製袋充填包装ができる。
【００１０】
【実施例】
図１は、本願第一発明及び本願第二発明に共通の実施例に係る縦形製袋充填包装機を示す。この実施例においては、製品充填筒としての製品落下充填筒２の上部を取り巻くように設けられた製袋器１に連続する包装フィルムＦを導き、製袋器１の案内作用により包装フィルムＦを製品落下充填筒２を包む筒状となるように曲成し、製品落下充填筒２の前側で包装フィルムＦの両端縁の内面同士を合わせ縦長帯状のガイド板１０，１０で両端縁の合わせを維持し、縦ヒートシール装置３の一対の縦長なバーヒータ３ａ，３ａで挟圧して電熱することにより縦シールａを施して、包装筒Ｈを形成している。製品落下充填筒２は、製袋器１で取り巻かれている部分のうち外形が実質的に円形に形成されている上半部を有しており、上半部と製袋器１との間に包装フィルムＦを通す数ミリの均等な環状隙間が確保されている。製品落下充填筒２の後面側には、上端から下端までにわたり偏平面部２ａ’が形成されており、偏平面部２ａ’上部の巾中央部にリブ７が付設されている。偏平面部２ａ’とリブ７に対応して、包装フィルムＦを偏平面部２ａ’とリブ７に密着するように曲成ガイドする一対のフィルムガイド板９，９が設けられている。リブ７により包装フィルムＦの巾中央の余剰寸法代がリブ７を密着して迂回するように曲成されてフィルム巾中央部を折り線としてフィルム巾中央折合わせ部分が形成される。フィルム巾中央折合わせ部分は、フィルム移送に伴い製品落下充填筒２の後側のリブ７の下側に設けられた後側縦ヒートシール装置８の一対の縦長なバーヒータ８ａ，８ａで挟圧されて電熱されることによって飾りの縦シールｂが施される。製品落下充填筒２の下方に一対に設けられているガセット板４，４を製品落下充填筒２の下端両側より垂下されている各二本の棒部材５，５の間に外方から突っ込むことにより、包装筒Ｈの両側にガセットを付ける。このとき、両側のガセットの折込方向は、両側の縦シールａ，ｂに一致される。被包装物は、製品落下充填筒２の下方に垂下する包装フィルムＦの包装筒Ｈ内に製品落下充填筒２を通して充填される。横ヒートシール・カット装置６は、包装筒Ｈの被包装物の上下を包装筒Ｈが偏平となるように挟圧して横シールを施すとともに、下の袋の上部横シールｆと一つ上の袋の下部横シールｄの間を横にカットすることにより、包装筒Ｈから被包装物がガゼット付き角床袋に包装された袋包装体を切り出すことができる。
【００１１】
製品落下充填筒２は、円筒材の後面を上端から下端まで半筒状に切除して該切除開口を平板で閉じて溶接し、該平板が偏平面部２ａ’となる概略半筒状の偏平筒状に形成された製品落下充填筒本体２ａを有している。製品落下充填筒本体２ａの偏平面部２ａ’上部に支持具２ｅがボルト２ｄ，２ｄで固定されており、製品落下充填筒２が、支持具２ｅにボルト２ｆ，２ｆで固定される半筒板２ｂを有することにより、製品落下充填筒本体２ａの製袋器１で取り巻かれている上半部は外径が実質的に円形となり、製袋器１と製品落下充填筒本体２ａの円筒面及び半筒板２ｂとの間に包装フィルムＦを通す数ミリの均等な環状隙間が確保される。また、機高を低く抑えるため、上端を斜めにカットしてホッパー２ｃと一体に結合している。
【００１２】
製品落下充填筒本体２ａの偏平面部２ａ’に左右一対に対設された縦長帯状のフィルムガイド板９，９は、水平断面がアングル形である上部９ａで、リブ７を挟むようにリブ７と偏平面部２ａ’に近接していて、包装フィルムＦの巾中央の余剰寸法代をリブ７に密着して該リブ７を迂回するように曲成ガイドする役目を果たしている。フィルムガイド板９，９は、また、上部９ａより下側部分９ｂが偏平面部２ａ’に近接する縦長帯状に形成されていて、包装フィルムＦがリブ７を密着して迂回しリブ７の下側で折り合わさる状態を確保するとともに、包装フィルムＦが製品落下充填筒本体２ａの偏平面部２ａ’に引き続き密着する状態を確保する役目も果たしている。
【００１３】
縦ヒートシール装置３は、開閉自在な一対の縦長なバーヒータ３ａ，３ａを有し、後側縦ヒートシール装置８は、開閉自在な一対の縦長なバーヒータ８ａ，８ａを有している。そして、各ヒートシール装置３，８は、フィルム移送の間欠停止時に一対のバーヒータ３ａ，３ａ又は８ａ，８ａを閉じて包装フィルムＦを挟着して電熱することによって縦シールａ及び飾りの縦シールｂを形成し、フィルム移送時には開くように構成されている。
【００１４】
一対のガセット板４，４は、落下充填筒２の下方前側と下方後側に備えられ、図示しない各側のエアシリンダの作動により開閉されるようになっており、包装筒Ｈが各二本の棒部材５，５を円筒状に包んでいた状態から、一対のガセット板４，４が各二本の棒部材５，５の間に外方から突っ込むことにより、左右に対向する棒部材５，５の間の円弧を描いていた弛みを各二本の棒部材５，５の間に引き寄せて左右に対向する棒部材５，５の間がピンと張られ二本の棒部材５，５の間が押し込められた形状とする。即ち、包装筒Ｈにはガセットが付けられる。
【００１５】
製品落下充填筒２の下端両側より垂下されている各二本の棒部材５，５は、外方へ向かって所要斜めに延びてから垂下しており、製袋されるガセット袋の縦四方辺の型取りの役目をする。
【００１６】
横ヒートシール・カット装置６は、昇降用エアシリンダ６ｄにより昇降自在な昇降台枠６ｃに、ヒータ開閉用エアシリンダ６ｅ，６ｅにより開閉自在な水平に対向一対の横長な二条シール形のバーヒータ６ａ，６ａと、一方のバーヒータ６ａに付随して移動しさらにカッター用エアシリンダ６ｆにより突っ切り移動自在なカッター６ｂとを有している。昇降用エアシリンダ６ｄとヒータ開閉用エアシリンダ６ｅ，６ｅの共同作用により、一対のバーヒータ６ａ，６ａが閉じて下降し開いて上昇復帰するボックスモーションを行い、横ヒートシール・カットとフィルム移送を行うことができる。
【００１７】
続いて、上述のように構成された本願第二発明による縦形製袋充填包装機の実施例の作用を説明する。製品落下充填筒２の製袋器１で取り巻かれている部分の上半部の外形が実質的に円形に形成され製袋器１との間に包装フィルムＦを通す数ミリの均等な環状隙間が確保されているので、包装フィルムＦは、製品落下充填筒２に密着して円筒に曲成される種類と、製品落下充填筒２から離れて製袋器１の円筒部に密着して円筒に曲成される種類のいずれでも、折り径が同一になるように円筒状に曲成される。包装フィルムＦが製品落下充填筒２の偏平面部２ａ’に移送されると、偏平面部２ａ’に対応するフィルム部分（フィルム巾中央部）に飾りの縦シールｂを形成するための余剰寸法代が生じる。また製品落下充填筒２と製袋器１の隙間が小さいから、厚い包装フィルムやアルミニウムの薄膜をベースとして積層した包装フィルムであっても、製袋器１の頂上部のところで折り返される際にフィルム巾方向に波（フィルムの暴れ）が生じることが防止され、皺や傷が生じないように製品落下充填筒２を包む綺麗な筒状に曲成される。包装フィルムＦの両端縁が製品落下充填筒２の前側で内面同士を合わされ、縦ヒートシール装置３は、フィルム移送停止時にエアシリンダ３ｂが作動し、一対のヒートシールバー３ａ，３ａがフィルム両端縁を挟圧して電熱することによって、縦シールａを施す。また、包装フィルムＦの偏平面部２ａ’に対応する巾中央部分は、製品落下充填筒２の偏平面部２ａ’でフィルムガイド板９，９のガイド作用により偏平面部２ａ’に密着するとともにリブ７を密着迂回するように曲成される。包装フィルムＦのリブ７を密着迂回する余剰寸法部分は、リブ７の下側に移送されたところでフィルム内面同士が自然に折り合い、後側縦ヒートシール装置８は，縦ヒートシール装置３のシール作動と同時のフィルム移送停止時に、エアシリンダ８ｂが作動して一対のヒートシールバー８ａ，８ａがフィルム内面同士が折り合った部分を挟圧して電熱することによって、飾りの縦シールｂを施し、フィルム移送開始前にエアシリンダ８ｂの復帰作動により一対のヒートシールバー８ａ，８ａを開く。こうして、製品落下充填筒２の下方に前側に縦シールａ、後側に飾りの縦シールｂが施された包装筒Ｈが垂下する。続いて、一対のガセット板４，４が包装筒Ｈの縦シールａ，ｂを両側の各二本の棒部材５，５の間の包装筒Ｈ内方に外方から突っ込んで押し込むことにより、包装筒両側に縦シールａ，ｂが最奥位置を占めるガセットが付けられる。しかる後、ヒータ開閉用エアシリンダ６ｅ，６ｅの作動により一対のバーヒータ６ａ，６ａが閉じて、皺がない下部横シールｄを施す。この時点で、一定量の被包装物が製品落下充填筒２を通して落下充填される。カッター用エアシリンダ６ｆの作動によりカッター６ｂが二条の横シールｄ，ｆの高さ方向中央へ突っ切り移動して製品落下充填筒２の下方に垂下する包装フィルムＦよりなる包装筒Ｈを挟着して二条の横シールｄ，ｆを施すとともにシールｄ，ｆ間を横にカットする。引き続いて、昇降用エアシリンダ６ｄの作動により昇降台枠６ｃが下降して一対のバーヒータ６ａ，６ａが包装筒Ｈを一袋分引下げる。その後、ヒータ開閉用エアシリンダ６ｅ，６ｅとカッター用エアシリンダ６ｆが逆作動して一対のバーヒータ６ａ，６ａが開くとともにカッター６ｂがバーヒータ６ａから引っ込んで袋切り離しが行われる。次いで、昇降用エアシリンダ６ｄの復帰作動により一対のバーヒータ６ａ，６ａが上昇復帰する。こうして、横ヒートシール・カット装置６がフィルム移送を行い製品落下充填筒の下方からフィルム移送を行うから、製品落下充填筒の径が小さい場合であっても、各縦シールのシール内端部の際に、斜めに並行する短い皺が連続して生じるのを防止することができる。以上の動作を繰り返すことによって、形態上袋の表裏がなく、ガゼットが縦シールによって補強されて角床袋の形状を良好に維持できる袋による製袋充填包装を連続して行うことができる。
【００１８】
【発明の効果】
以上説明したように、本願第一発明の縦形製袋充填包装機によれば、製品充填筒の前後において形成された縦シール及び飾りの縦シールをそれぞれガセット板の折り込みによって袋の内方に押し込んで補強されたガゼットが形成でき、図２に示すように、縦シールが袋の表裏に現れないことによって形態上、袋の表裏がなく、袋内に被包装物を充填したとき袋内の被包装物により押されても袋の下部両側部が膨らず角床袋の形状が良好に維持できるガセット付き角床袋形状を製袋し得る。また本願第二発明の縦形製袋充填包装機によれば、上記本願第一発明と同一の効果が得られるのに加えて、製品充填筒の中程でブリッジが生じないとともに、フィルムの円筒曲成が製品充填筒に密着する性質があるナイロン系やポリエステル系の包装フィルムであっても飾り縦シールを良好に形成することができ、また厚い包装フィルムやアルミニウムの薄膜をベースとして積層した包装フィルムであっても、製袋器の頂上部のところで折り返される際にフィルム巾方向に波が生じて傷になるということがないように製袋し得る。

When the film transfer is stopped at the same time, the air cylinder 8b is activated and the pair of heat seal bars 8a, 8a presses and heats the portion where the inner surfaces of the film are folded together, thereby giving a decorative vertical seal b. Before the transfer starts, the pair of heat seal bars 8a and 8a are opened by the return operation of the air cylinder 8b. In this way, the packaging cylinder H with the vertical seal a on the front side and the decorative vertical seal b on the rear side of the product drop filling cylinder 2 hangs down. Subsequently, the pair of gusset plates 4 and 4 push the vertical seals a and b of the packaging cylinder H into the packaging cylinder H between the two bar members 5 and 5 on both sides by pushing from the outside. Gussets in which the vertical seals a and b occupy the innermost position are attached to both sides of the packaging cylinder. Thereafter, the pair of bar heaters 6a and 6a are closed by the operation of the heater opening and closing air cylinders 6e and 6e, and a lower horizontal seal d without wrinkles is applied. At this point, a certain amount of the object to be packaged is dropped and filled through the product drop filling cylinder 2. When the cutter air cylinder 6f is operated, the cutter 6b cuts and moves to the center in the height direction of the two horizontal seals d and f, and sandwiches the packaging cylinder H made of the packaging film F hanging below the product dropping and filling cylinder 2. Then, two horizontal seals d and f are applied, and the space between the seals d and f is cut horizontally. Subsequently, the lift frame 6c is lowered by the operation of the lift air cylinder 6d, and the pair of bar heaters 6a, 6a pulls down the packaging cylinder H by one bag. Thereafter, the heater open / close air cylinders 6e and 6e and the cutter air cylinder 6f are operated in reverse to open the pair of bar heaters 6a and 6a, and the cutter 6b is retracted from the bar heater 6a to separate the bag. Next, the pair of bar heaters 6a and 6a are raised and returned by the return operation of the elevating air cylinder 6d. Thus, since the horizontal heat sealing / cutting device 6 transfers the film and transfers the film from below the product dropping and filling cylinder, even if the diameter of the product dropping and filling cylinder is small, the inner end of the seal of each vertical seal In this case, it is possible to prevent a series of short wrinkles that are obliquely parallel. By repeating the above operations, bag making and packaging can be continuously performed with a bag that can maintain the shape of the square bed bag with the gusset being reinforced by the vertical seal without the front and back of the bag.
