Description

【０００１】
【発明の属する技術分野】
本発明は、スライスされた複数枚単位の食パンを、袋開口手段で開口された袋内に送り込んで袋詰めするよう構成された食パン袋詰め機における物品移送装置に関するものである。
【０００２】
【従来の技術】
スライサーで所定の幅にスライスされたスライスパンを１斤、１．５斤等の所定枚数単位で纏めた食パンを、食パン袋詰め機によって袋詰め包装する場合、該食パンは、袋詰め機の供給コンベヤに対して、そのスライスパンの重なり方向が袋詰め機における物品移送方向と直交する姿勢で送り込まれた後、搬送ベッド上を押送されることで、袋開口手段によって開口状態となった袋の口部から袋内部に押込まれる。そして、袋の底部までに至った食パンが更に押送されて前進移動することで、袋の保持部に支持されていた袋が離脱して袋と共に食パンが下流側に移送されて、一方が開口状態の袋詰め品が得られるようになっている。
【０００３】
前述したように、袋詰め機に供給される食パンは、その重なり方向が袋詰め機での物品移送方向に対して直交する姿勢で取り扱われることが殆どであり、該食パンを搬送ベッド上を押送する際に、搬送路の食パンを挟む両側部にガイド板を配設したり、あるいは側部ガイドコンベヤ等（例えば特許文献１）を設けること等により食パンのスライス面を支持することで、該食パンを、その重ね状態に乱れが発生することなく安定した姿勢で袋詰め位置まで良好に移送することができる。
【０００４】
なお、食パンが収容された一方が開口状態の袋詰め品は、袋詰め機の下流側に直線的に接続されたシール装置によってその袋の開口部がシールされ、更に下流側に接続される結束装置によって結束具が装着されることで、袋の開口部側が該結束具によって絞込み結束された袋詰め包装体が得られるよう構成される（例えば特許文献２）。

【０００６】
【発明が解決しようとする課題】
しかしながら、食パンを袋詰機の袋詰め位置へ移送する際の姿勢が、前記の姿勢とは９０度異なる状態、すなわちスライスパンの重なり方向が物品移送方向と同一の場合は、スライス面が物品移送方向の前後に臨んでいるため、従来のように側部ガイド板や側部ガイドコンベヤを設置しても安定した袋詰めが困難であった。すなわち、各スライスパンの外形寸法は不揃いであるため、側部ガイド板や側部ガイドコンベヤによっては個々に重なっているスライスパンの側部を一様に支持できず、食パンが搬送ベッド上を押送されて袋の口部に向けて前進移送される際に、個々のスライスパンの上部が移送方向に前傾する等によって姿勢が乱れ、移送時の重なり状態を維持することが困難で良好な袋詰めを行なうことができなかった。
【０００７】
また、食パンが収容された袋詰め品を前記シール装置に向けて移送する際に、該食パンの移送方向後側、すなわち袋の開口部側は支持されていないため、その移送時に個々のスライスパンの上部が移送方向に後傾する等によって姿勢が乱れることがあり、シールを良好に行なうことが困難となる難点も指摘される。
【０００８】
【発明の目的】
本発明は、前述した従来の技術に内在している前記課題に鑑み、これを好適に解決するべく提案されたものであって、袋詰め機の物品移送方向に食パンの重なり方向が沿う姿勢で移送される場合であっても、安定した姿勢で移送ができる食パン袋詰め機における物品移送装置を提供することを目的とする。
【０００９】
【課題を解決するための手段】
前述した課題を解決し、所期の目的を好適に達成するため、本発明に係る食パン袋詰め機における物品移送装置は、
スライスされた複数枚単位の食パンを、袋の口部から底部側に向けて移送する際に、その重なり方向が移送方向に沿う姿勢で移送する食パン袋詰め機の物品移送装置であって、
前記袋を開口すると共に、該袋の開口時において物品の通過を許容する袋開口手段と、
前工程から供給された食パンを、その重なり方向が移送方向に沿う姿勢で前記袋開口手段に向けて押送する押送部材を備えた押送手段と、
前記押送部材で押送される食パンの前方に臨み、該押送部材とによって食パンを挟み込み保持して前記袋開口手段における物品通過入口まで移送する支持部材を備える保持移送手段とからなり、
前記保持移送手段は、前記押送部材が食パンを支持部材とにより前後で挟み込み保持し得る位置に到来するタイミングで、該支持部材の前進移動を開始すると共に、押送部材の物品押送速度に同調する速度で支持部材を移動するよう設定されていることを特徴とする。
【００１０】
【発明の実施の形態】
次に、本発明に係る食パン袋詰め機における物品移送装置につき、好適な実施例を挙げて、添付図面を参照しながら以下説明する。
【００１１】
図１に示す食パン袋詰め機（以下単に袋詰め機とも云う）１０における物品移送装置１１の上流側には、ブロック状の食パンを所定厚みでスライスする図示しないスライサーの下流側に配設された搬送コンベヤ１２が略直交する状態で接続されている。この搬送コンベヤ１２のテーブル１３には、図２または図８に示す如く、スライスパンをそのスライス面が相互に当接するよう重ね合わせた複数枚単位の食パン１４が、その重なり方向が当該搬送コンベヤ１２での物品搬送方向と直交する姿勢で載置される。そして、テーブル１３を挟んで物品搬送方向と交差する方向に離間して走行する一対の無端チェン（図示せず）間に所定間隔で架設されて、テーブル１３上を移動する押し棒１５が、該食パン１４をベルトコンベヤからなる渡りコンベヤ１６に向けて押送するよう構成される。またテーブル１３の上方に、物品搬送方向と交差する方向に離間して一対のガイド部材１７，１７が搬送方向と平行に配設され、前記食パン１４は両ガイド部材１７，１７にスライス面が支持されつつ搬送されるようになっている。
【００１２】
前記物品移送装置１１の最上流側に配置される前記渡りコンベヤ１６は、前記搬送コンベヤ１２による物品搬送方向と同一方向に食パン１４を搬送するよう構成され、該渡りコンベヤ１６に受け渡された食パン１４は、その物品搬送方向と交差する方向に離間して配設された側部ガイド１９，２０に案内されて、物品搬送方向の前方所定位置に配設されたストッパ１８に当接する位置まで移送されるようになっている。なお、物品移送装置１１における物品移送方向の下流側に位置する一方の側部ガイド１９は、該渡りコンベヤ１６から後述する供給コンベヤ２４への食パン１４の移動を許容するよう物品移送路を除く搬送コンベヤ１２に近接する部分にのみ設けられると共に、上流側に位置する他方の側部ガイド２０は、後述する押送コンベヤ２３における押送部材２２の通過を許容する形状に設定されている。
【００１３】
前記渡りコンベヤ１６の上方には、図１に示す如く、物品移送装置１１における物品移送路の上方を循環走行する無端チェン２１に所定間隔で多数の押送部材２２を取付けた押送手段としての押送コンベヤ２３が配設される。そして、渡りコンベヤ１６に移載された食パン１４は、その重なり方向が物品移送方向（食パン１４を袋３０の口部から底部側に向けて移送する方向）に沿う姿勢（スライス面が移送方向の前後を向く姿勢）で押送部材２２によって、後述する袋開口手段３２を経て処理装置としてのシール装置４５に向けて移送されるようになっている。
【００１４】
前記渡りコンベヤ１６の一側方、すなわち物品移送装置１１における物品移送方向の下流側には、該渡りコンベヤ１６の物品搬送面と同一レベルに物品移送面を設定したベルトコンベヤからなる供給コンベヤ２４が配設されている。また供給コンベヤ２４の上方には、図３および図４に示す如く、その物品移送路を挟んで物品移送方向と交差する幅方向に離間した位置に、回転コンベヤからなる移送コンベヤ２５，２５が対向的に配設されている。各移送コンベヤ２５は、物品移送方向に離間する一対のプーリ間に回転可能に巻掛けられた無端ベルト２６のベルト面が、供給コンベヤ２４の物品移送面と直交する姿勢で配置されると共に、該無端ベルト２６には走行方向に離間して複数の支持部材２７が配設されている。そして、幅方向で対向する一対の移送コンベヤ２５，２５の支持部材２７，２７により、前記食パン１４における物品移送方向の前側を支持して、前記押送部材２２とで該食パン１４を前後で挟み込み保持し得るよう構成される。なお、押送コンベヤ２３が連続運転中に移送コンベヤ２５，２５が休止状態となっているときでも、支持部材２７は、両支持部材２７，２７が対向する姿勢において、その間を前記押送部材２２が通過するのを許容する形状に形成されている（図４参照）。
【００１５】
前記各移送コンベヤ２５と供給コンベヤ２４はサーボモータ２８により夫々独立して駆動されると共に、支持部材２７の移動速度は、供給コンベヤ２４のべルト走行速度と同速となるよう設定され、かつ前記押送コンベヤ２３による物品押送速度に同調する速度に設定されている。また各移送コンベヤ２５における物品移送方向の上流側に位置する支持部材２７は、前記搬送コンベヤ１２から渡りコンベヤ１６への食パン１４の受け渡しに際して、該食パン１４における物品移送方向の前方位置に待機しているように設定され、食パン１４が搬送コンベヤ１２から渡りコンベヤ１６に移送される際の側部ガイドとしても機能するようにしてある。そして、渡りコンベヤ１６に移載された食パン１４に対し、前記押送部材２２が該食パン１４を支持部材２７，２７とで前後に挟み込み保持し得る位置に到来するタイミングで該支持部材２７，２７の前進移動を開始するように、移送コンベヤ２５が前記サーボモータ２８により駆動制御される。なお、スライスされた食パン１４のスライス厚や袋詰単位数が変更された際の食パン１４の重なり寸法の大小に応じて、例えば品種設定操作等を行なう等によって、食パン１４の後方から接近する前記押送部材２２の現在位置に対する支持部材２７，２７の前進移動開始タイミングが設定変更可能になっていることが好ましい。また、支持部材２７は、後述する袋開口手段３２の物品通過入口まで食パン１４の前側を支持した状態で移動するようになっている。更に、食パン１４を載置して移送する前記供給コンベヤ２４の移送終端は、図５に示す如く、移送コンベヤ２５，２５の移送終端より袋開口手段３２に近接した下側保持部材３４まで至る位置（物品通過入口）まで延設されている。実施例では、前記供給コンベヤ２４と、一対の移送コンベヤ２５，２５とから保持移送手段を構成している。
【００１６】
ここで、前記支持部材２７，２７の前進移動開始タイミングとなる前記押送部材２２の挟み込み保持し得る位置は、支持部材２７，２７と押送部材２２との前後間隔が食パン１４の重なり寸法と略同一となる位置に限らず、支持部材２７，２７と押送部材２２とが食パン１４を挟む前後に位置して保持状態で移送する際に、食パン１４の重なり状態が乱れて移送が困難とならない前後間隔であれば、食パン１４の重なり寸法より大きく設定された位置であってもよい。
【００１７】
図６に示す如く、前記供給コンベヤ２４の下流側に袋載置台２９が配設され、該載置台２９に、多数の袋３０が、その口部側を物品移送方向の上流側に指向して積層載置された状態で、その口部側が保持爪３１で押圧されており、図示しないエア吹込み手段等で上流側上方から口部に向けて圧力エアーを吹付けることで、積層最上部の袋が開口されるよう構成される。
【００１８】
前記供給コンベヤ２４と袋載置台２９との間には、該袋載置台２９に積層状態で載置されている最上部の袋３０を開口保持する袋開口手段３２が、物品移送方向に進退移動可能に配設されている。この袋開口手段３２は、食パン１４の４隅部に対応する位置に配置される４つの保持部材３３，３３，３４，３４を備え、上側に位置する一対の上側保持部材３３，３３と、下側保持部材３４，３４とは下流端部が相互に近接・離間移動可能に構成されている（図１参照）。そして、下流端部が近接した姿勢の各保持部材３３，３３，３４，３４が前進移動しつつ各保持部材３３，３３，３４，３４の下流端部が離間移動することで、前記圧力エアーにより開口されている袋３０に挿入された後のタイミングで、図６に示す如く、該袋３０の口部を食パン１４が通過可能な略矩形状に開口保持するよう構成される。また、上側保持部材３３，３３の間を、押送部材２２が通過するよう構成されて、該袋開口手段３２により開口された袋３０に向けて食パン１４を上流側から押送して押込むようになっている。
【００１９】
前記移送コンベヤ２５，２５による移送終端部から、前記袋３０を開口している状態の袋開口手段３２における４つの保持部材３３，３３，３４，３４で画成される物品通過入口より内方までに亘り、前記食パン１４が通過する際にその外方から該食パン１４を弾性的に支持する接触ガイド手段としての側部接触ガイド部材３５，３５および上部接触ガイド部材３６が配設される。すなわち、物品移送路を挟む幅方向の両側方に、ホルダ３７に対して上下方向に所定間隔で複数（実施例では３枚）の支持板３８が物品移送路と平行に配設され、各支持板３８の物品移送路側の内面に、物品移送方向に所定間隔毎に複数（実施例では４枚）の側部接触ガイド部材３５が配設されている。この側部接触ガイド部材３５は、食パン１４と接触した際に該食パン１４を傷付けることなく弾性変形可能な樹脂プレートからなり、図３に示す如く、下流端部側が物品移送路に向けて突出するよう湾曲し、幅方向に対向する両側部接触ガイド部材３５，３５の突出部の対向間隔は、食パン１４の外側寸法より狭く設定される。すなわち、両側部接触ガイド部材３５，３５の間を通過する食パン１４は、該ガイド部材３５，３５により前側部が外方両側から弾性的に支持され、該食パン１４の重なり状態が乱れるのを防止するようになっている。なお、上流側の側部接触ガイド部材３５の下流端部は、下流側の側部接触ガイド３５の上流部分に一部重なるよう位置決めされ、食パン１４の前側部は物品移送方向に並んでいる複数の側部接触ガイド部材３５により連続的に支持されるよう構成される。
【００２０】
前記上部接触ガイド部材３６は、物品移送路の上方に配設された軸部３９に対して上流端部が回動可能に枢支されて、下流側に向かうにつれて下方傾斜するよう垂れ下がり、その下流端部は前記押送部材２２により押送される食パン１４の上縁部に接触可能に構成される。また上部接触ガイド部材３６は、図示しないバネ等の弾性部材により常に傾斜状態に保持され、食パン１４の上縁部に対して弾性部材の弾力作用下に弾性的に接触して重なり状態が乱れるのを防止するようになっている。なお、弾性部材の弾力は、食パン１４を変形させない値に設定される。また上部接触ガイド部材３６は、前記押送部材２２と干渉しない位置に位置決めされている。
【００２１】
図６に示す如く、前記袋載置台２９の下流側上方には、該袋載置台２９に載置されている袋３０の底部側に対して上方から圧力エアーを吹き付けるエアーノズル４０が設けられている。このエアーノズル４０からは、前記袋開口手段３２により袋３０が開口された後に袋底部側に向けて圧力エアーが吹付けられ、該袋底部側を押圧して変形することで、袋開口手段３２を通過した食パン１４の前部に袋内面を接触させて、その抵抗により該食パン１４が前倒れすることなく袋底部まで押込まれるよう構成される。なお、袋底部への食パン１４の押込みが完了するタイミングで、エアーノズル４０からの圧力エアーの吹付けは停止されるよう設定される。
【００２２】
前記袋載置台２９（食パン１４が袋３０に押込まれる袋詰め位置）の下流側には、前記シール装置４５までの間に、袋詰めされた食パン１４を該シール装置４５の第１送りコンベヤ４８（後述）に受け渡し供給する受け渡し手段４１が配設されている。この受け渡し手段４１は、図７に示す如く、袋詰めされた食パン１４を載置して下流側に移送するベルトコンベヤからなる接続コンベヤ４２と、該接続コンベヤ４２における物品移送路を挟む幅方向両側で食パン１４を袋３０と共に弾性的に挟持して移送する一対の保持コンベヤ４３，４３とから構成される。各保持コンベヤ４３は、物品移送方向に離間する一対のプーリ間に回転可能に巻掛けられた無端ベルト４４のベルト面が、接続コンベヤ４２の物品移送面と直交する姿勢で配置されると共に、該ベルト面にスポンジを材質とする多数の弾性体を配設して構成される。なお、前記接続コンベヤ４２および保持コンベヤ４３，４３の物品移送速度は、前記押送コンベヤ２３の物品押送速度と同調する速度に設定され、各コンベヤ４２，４３，４３に夫々配設されたモータ（図示せず）によって駆動されるよう構成されている。
【００２３】
前記受け渡し手段４１の移送終端部は、前記押送コンベヤ２３の押送終端部より下流側まで延在しており、袋詰めされた食パン１４が受け渡し手段４１で移送される間に、前記押送部材２２は無端チェン２１に対する取付部を支点として食パン１４から物品移送方向上流側に離間するよう回動することで、袋３０の口部から退避するよう構成されている。また前記接続コンベヤ４２における食パン１４が載置される物品移送面は、図１に示す如く、物品移送方向の下流側に向けて下方傾斜するよう設定され、前記押送コンベヤ２３の押送が解除された以降の食パン１４が袋底部に支持された状態で移送され、これにより袋３０の口部側に後傾して姿勢が乱れるのを防止することができる。なお、受け渡し手段４１の移送終端部は、少なくとも押送コンベヤ２３の押送終端部まで延設されていればよく、袋詰めされた食パン１４が後側を押送部材２２で支持された状態でシール装置４５に受け渡されるようになっていてもよい。
【００２４】
前記受け渡し手段４１の下流側に接続されるシール装置４５は、図１に示す如く、袋詰めされた食パン１４の移送路を挟んで上下に対向し、袋３０における食パン１４の収容部位より口部側を熱シールする上下一対のシール体４６，４７と、該シール体４６，４７によるシール位置を挟んで上流側に位置する第１送りコンベヤ４８および下流側に位置する第２送りコンベヤ４９とから基本的に構成され、これらシール体４６，４７および両送りコンベヤ４８，４９の作動機構や動作については、例えば本件出願人の出願に係る特開２００２−１９３２０３号に詳述された機構および動作を採用し得る。また第１送りコンベヤ４８の上方には、同じく特開２００２−１９３２０３号に詳述されたと同様の物品ガイド手段５０が配設され、該物品ガイド手段５０により袋詰めされた食パン１４の姿勢および移送位置を一定に維持してシール位置まで案内するよう構成されている。
【００２５】
前記両送りコンベヤ４８，４９における食パン１４が載置される物品移送面は、前記受け渡し手段４１における接続コンベヤ４２の物品移送面と同一角度で、物品移送方向の下流側に向けて下方傾斜するよう設定され、シール位置に移送される食パン１４の重なり状態に乱れを生ずるのを抑制するよう構成される。なお、接続コンベヤ４２の下流端と第１送りコンベヤ４８の上流端との高さ位置は、袋詰めされた食パン１４の受け渡しが円滑に行ない得るよう位置決めされている。
【００２６】
図８に示す如く、前記シール装置４５の下流側に位置する第２送りコンベヤ４９の下流側に、物品移送方向が直交する搬出コンベヤ５１が接続され、該搬出コンベヤ５１に受け渡されて移送方向が９０°変換された食パン１４が収容されている袋３０の口部側が、該搬送コンベヤ５１の一側方に配置された結束装置５２により結束されるようになっている。
【００２７】
【実施例の作用】
次に、前述した実施例に係る物品移送装置の作用につき説明する。図２および図８に示す如く、食パン１４は、その重なり方向が物品搬送方向と直交する姿勢で、前記搬送コンベヤ１２により押送されて、前記渡りコンベヤ１６に受け渡される。この食パン１４は、側部ガイド１９，２０に案内されつつストッパ１８に当接する位置まで搬送される。このとき、前記移送コンベヤ２５，２５における物品移送方向の上流側に位置する支持部材２７，２７は、渡りコンベヤ１６に受け渡される食パン１４における物品移送方向の前方に臨んでおり、該食パン１４のスライス面が臨む前部を支持してスライスパンが倒れないようになっている。
【００２８】
前記食パン１４が渡りコンベヤ１６の搬送終端部まで至った後の所定タイミングで、該渡りコンベヤ１６の搬送方向と直交する方向に向けて前記押送コンベヤ２３の押送部材２２が前進移動して該食パン１４の後方から接近し、前記押送部材２２が食パン１４を前記支持部材２７，２７とで前後に挟み込み保持し得る位置に到来するタイミングで、前記移送コンベヤ２５，２５のサーボモータ２８，２８回転駆動して支持部材２７，２７の前進移動を開始することで、該食パン１４は支持部材２７，２７と押送部材２２とで、その重なり方向が物品移送方向に沿う姿勢で前後を保持されると共に、一方の側部が前記ストッパ１８に案内されつつ該食パン１４が供給コンベヤ２４に載置されて、前記袋開口手段３２の物品通過入口まで移送される。すなわち、物品移送方向に重なり方向が沿う姿勢で移送される食パン１４の前後は、支持部材２７，２７と押送部材２２とで支持されているから、各スライスパンが物品移送方向の前側あるいは後側に傾倒して重なり状態が乱れることはない。また、前記供給コンベヤ２５および移送コンベヤ２５，２５は押送部材２２の押送速度に同調する速度で移動しているから、食パン１４の外縁部が擦れることはなく、該食パン１４に損傷を与えることはない。なお、サーボモータ２８で駆動される移送コンベヤ２５における支持部材２７の前進移動開始タイミングを可変可能に構成してあるから、食パン１４の重ね枚数等に応じて重なり寸法が変化した場合にも簡単に設定変更でき、品種変更等の対応が容易となる。
【００２９】
前記移送コンベヤ２５，２５の支持部材２７，２７が移送終端部に至ると、該支持部材２７，２７は食パン１４の前側から離間退避し、該食パン１４は前記押送部材２２により引続き袋開口手段３２に向けて押送される。前述したように、前記供給コンベヤ２４の移送終端は、移送コンベヤ２５，２５の移送終端より下流側に延出しているから、食パン１４の下面は該供給コンベヤ２４により袋開口手段３２の物品通過入口に近接する位置まで支持される。図５に示す如く、前記支持部材２７，２７による前側の支持が解除された食パン１４は、前記袋開口手段３２の物品通過入口に至るまでの間は、前記供給コンベヤ２４により下面が支持された状態で、前記側部接触ガイド部材３５，３５および上部接触ガイド部材３６が前側の両側部および上部に弾性的に接触することで各スライスパンが前側に傾倒するのは防止され、重なり状態が乱れることなく袋開口手段３２を通過する。この袋開口手段３２は、食パン１４が物品通過入口に到来するタイミングで前進移動しつつ上側保持部材３３，３３と下側保持部材３４，３４との下流端部が相互に離間移動することで、前記４つの保持部材３３，３３，３４，３４の下流端部が圧力エアーにより開口されている袋３０に挿入された後のタイミングで、図６に示す如く、該袋３０が開口保持される。
【００３０】
また、前記袋開口手段３２により袋３０が開口保持された後のタイミングで、前記エアーノズル４０から前記袋載置台２９に載置されている袋３０の底部側に向けて下流側上方から圧力エアーが吹付けられ、該袋底部側は押圧されて変形する。従って、前記押送部材２２により押送される食パン１４の前部は、圧縮された袋３０の内面に接触しつつ移動することとなり、その抵抗によりスライスパンが前側に傾倒せず、袋底部まで重なり状態が乱れることなく押込まれる。
【００３１】
袋詰めされた食パン１４は、引続き押送部材２２により押送され、前記袋載置台２９での袋３０の保持が解除されることで、食パン１４は袋３０と共に袋載置台２９から前記受け渡し手段４１の接続コンベヤ４２に移載される。この接続コンベヤ４２に載置されて押送部材２２により押送される袋詰めされた食パン１４は、前記一対の保持コンベヤ４３，４３により両外側方が弾性的に挟持された状態で移送される。保持コンベヤ４３，４３の搬送終端より上流側に設定された前記押送部材２２の押送終端部に至ると、該押送部材２２は食パン１４の後側から離間して袋３０の口部から退避し、該食パン１４の後側は支持されなくなる。しかるに、実施例の物品移送装置１１では、前記接続コンベヤ４２における食パン１４が載置される物品移送面が、図１に示すように物品移送方向の下流側に向けて下方傾斜するよう設定されているから、袋内部の食パン１４は、袋底部に前側が支持された前傾姿勢となり、該食パン１４が袋口側に後傾して姿勢が乱れるのは防止される。
【００３２】
前記袋詰めされた食パン１４は、受け渡し手段４１から前記シール装置４５に受け渡され、該シール装置４５により食パン１４が収容された袋３０の口部側が熱シールされ、下流側に設けられた前記結束装置５２により結束される。袋詰めされた食パン１４を移送するシール装置４５の前記第１および第２送りコンベヤ４８，４９の物品移送面は、前記受け渡し手段４１の接続コンベヤ４２における物品移送面と同様に、物品移送方向の下流側に向けて下方傾斜しているから、シール装置４５によるシール動作時においても袋内の食パン１４の重なり状態が乱れることはなく、良好なシールを施すことができる。
【００３３】

TECHNICAL FIELD OF THE INVENTION
The present invention relates to an article transfer device in a bread bagging machine configured to feed sliced bread in units of a plurality of sheets into a bag opened by a bag opening means and pack the bags.
[0002]
[Prior art]
When breads obtained by combining sliced bread sliced to a predetermined width by a slicer into a predetermined number of units such as 1 loaf, 1.5 loaves and the like are packed in a bag by a bread bagging machine, the bread is supplied by a bagging machine. After the slice bread is fed to the conveyor with the overlapping direction of the slice bread orthogonal to the article transfer direction in the bag filling machine, the bag is pushed on the transport bed, and the bag opened by the bag opening means is opened. It is pushed into the bag from the mouth. Then, the bread reaching the bottom of the bag is further pushed and moved forward, so that the bag supported by the bag holding portion is detached, and the bread is transported along with the bag to the downstream side, and one side is opened. Of bagged products.
[0003]
As described above, the bread supplied to the bagging machine is mostly handled in a posture in which the overlapping direction is orthogonal to the article transfer direction in the bagging machine, and the bread is pushed on the transport bed. At this time, the bread is provided by arranging guide plates on both sides of the bread in the conveying path, or by supporting a slice surface of the bread by providing a side guide conveyor or the like (for example, Patent Document 1). Can be satisfactorily transferred to the bag-packing position in a stable posture without disturbing the overlapping state.
[0004]
In addition, in the bagged product in which the bread is stored, one side of the bagged product is opened, the opening of the bag is sealed by a sealing device linearly connected to the downstream side of the bagging machine, and the binding unit further connected to the downstream side. When the binding device is attached by the device, a bag-packed package in which the opening side of the bag is narrowed and bound by the binding device is obtained (for example, Patent Document 2).
[0005]

JP-A-6-286704
[Patent Document 2]
JP-A-2002-193203
[0006]
[Problems to be solved by the invention]
However, when the posture at the time of transferring the loaf of bread to the bagging position of the bagging machine is different from the above posture by 90 degrees, that is, when the overlapping direction of the slice bread is the same as the direction of transporting the articles, the slice surface is moved at the same time. Because they face the front and rear in the direction, even if a side guide plate or a side guide conveyor is installed as in the related art, it is difficult to stably pack the bags. That is, since the outer dimensions of each sliced bread are not uniform, the side guide plates and the side guide conveyors cannot uniformly support the side portions of the sliced bread that are individually overlapping, and the bread is pushed on the transport bed. When the bag is transported forward toward the mouth of the bag, the posture is disturbed due to the upper part of each slice pan tilting forward in the transfer direction or the like, and it is difficult to maintain the overlapping state at the time of transfer, and it is a good bag. The stuffing could not be done.
[0007]
Further, when the packaged product containing the bread is transferred to the sealing device, the rear side in the transfer direction of the bread, that is, the opening side of the bag is not supported, so that each slice bread is transferred during the transfer. The posture may be disturbed due to, for example, the upper part of the body being tilted backward in the transport direction, and it is pointed out that it is difficult to perform a good seal.
[0008]
[Object of the invention]
The present invention has been proposed in view of the above-mentioned problems inherent in the conventional technology, and has been proposed to appropriately solve the problem. An object of the present invention is to provide an article transfer device in a bread bag stuffing machine that can transfer in a stable posture even when it is transferred.
[0009]
[Means for Solving the Problems]
In order to solve the above-described problems and appropriately achieve the intended purpose, the article transfer device in the bread bag filling machine according to the present invention includes:
An article transfer device for a bread bag stuffing machine that transfers sliced bread in units of a plurality of slices, when transferring from the mouth of the bag toward the bottom side, the overlapping direction is transferred in a posture along the transfer direction,
Bag opening means for opening the bag and allowing the passage of articles when the bag is opened,
Pushing means provided with a pushing member for pushing the bread supplied from the previous step toward the bag opening means in a posture in which the overlapping direction is along the transfer direction,

[0010]
BEST MODE FOR CARRYING OUT THE INVENTION
Next, an article transfer device in a bread bag stuffing machine according to the present invention will be described below with reference to the accompanying drawings by taking a preferred embodiment.
[0011]
In the bread bagging machine (hereinafter simply referred to as a bagging machine) 10 shown in FIG. 1, an upstream side of the article transfer device 11 is disposed downstream of a slicer (not shown) for slicing a block-shaped bread at a predetermined thickness. The transport conveyors 12 are connected in a substantially orthogonal state. As shown in FIG. 2 or FIG. 8, the table 13 of the transport conveyor 12 includes a plurality of sliced breads 14 in which sliced breads are overlapped so that their slice surfaces are in contact with each other. Is placed in a posture orthogonal to the article conveying direction in the above. Then, a push rod 15, which is erected at a predetermined interval between a pair of endless chains (not shown) that run apart in a direction intersecting the article transport direction with the table 13 interposed therebetween and moves on the table 13, The bread loaf 14 is configured to be pushed toward a transfer conveyor 16 composed of a belt conveyor. A pair of guide members 17, 17 are arranged above the table 13 in a direction intersecting with the article conveying direction and separated in a direction parallel to the conveying direction. It is conveyed while being performed.
[0012]
The transfer conveyor 16 disposed on the most upstream side of the article transfer device 11 is configured to transfer the bread 14 in the same direction as the article transfer direction by the transfer conveyor 12, and the bread transferred to the transfer conveyor 16. 14 is guided by side guides 19 and 20 disposed apart from each other in a direction intersecting the article transport direction, and transported to a position where it comes into contact with a stopper 18 disposed at a predetermined position in front of the article transport direction. It is supposed to be. The one side guide 19 located on the downstream side in the article transfer direction in the article transfer device 11 is a transport excluding the article transfer path so as to allow the movement of the bread 14 from the transfer conveyor 16 to the supply conveyor 24 described later. The other side guide 20, which is provided only in a portion close to the conveyor 12 and is located on the upstream side, is set to have a shape that allows the pushing member 22 in the pushing conveyor 23 to be described later to pass.
[0013]
As shown in FIG. 1, a pushing conveyor as a pushing means in which a large number of pushing members 22 are attached at predetermined intervals to an endless chain 21 which circulates and runs over an article transfer path in the article transfer apparatus 11 above the transfer conveyor 16. 23 are provided. Then, the bread 14 transferred to the transfer conveyor 16 has a posture in which the overlapping direction is along the article transfer direction (the direction in which the bread 14 is transferred from the mouth of the bag 30 toward the bottom) (the slice surface is in the transfer direction). With the pushing member 22 in a forward-backward orientation, the material is transferred to a sealing device 45 as a processing device via a bag opening means 32 described later.
[0014]
On one side of the transfer conveyor 16, that is, on the downstream side in the article transfer direction in the article transfer device 11, there is provided a supply conveyor 24 including a belt conveyor having an article transfer surface set at the same level as the article transfer surface of the transfer conveyor 16. It is arranged. As shown in FIGS. 3 and 4, transfer conveyors 25, 25 composed of rotary conveyors, are located above the supply conveyor 24 at positions spaced apart in the width direction intersecting the article transfer direction with the article transfer path interposed therebetween. It is arranged in a way. In each transfer conveyor 25, the belt surface of the endless belt 26 rotatably wound around a pair of pulleys separated in the article transfer direction is disposed in a posture orthogonal to the article transfer surface of the supply conveyor 24, and The endless belt 26 is provided with a plurality of support members 27 separated from each other in the running direction. Then, the front side of the bread 14 in the article transfer direction is supported by the support members 27, 27 of the pair of transfer conveyors 25, 25 facing each other in the width direction, and the bread 14 is sandwiched and held between the pushing member 22 and the pushing member 22. It is configured to be able to. In addition, even when the transfer conveyors 25 and 25 are in a rest state during the continuous operation of the pushing conveyor 23, the pushing member 22 passes through the supporting member 27 in a posture where the two supporting members 27 and 27 face each other. (See FIG. 4).
[0015]
The transfer conveyor 25 and the supply conveyor 24 are independently driven by a servomotor 28, and the moving speed of the support member 27 is set to be the same as the belt traveling speed of the supply conveyor 24, and The speed is set so as to synchronize with the article pushing speed by the pushing conveyor 23. Further, the support member 27 of each transfer conveyor 25 located on the upstream side in the article transfer direction waits at a position forward of the bread 14 from the transport conveyor 12 to the transfer conveyor 16 in the article transfer direction. So that the bread 14 functions as a side guide when the bread 14 is transferred from the transport conveyor 12 to the transfer conveyor 16. Then, with respect to the loaf of bread 14 transferred to the transfer conveyor 16, the pushing member 22 reaches the position where the loaf of bread 14 can be sandwiched and held by the supporting members 27, 27 back and forth, and the supporting members 27, 27 The drive of the transfer conveyor 25 is controlled by the servomotor 28 so as to start the forward movement. In addition, in accordance with the size of the overlapping size of the bread 14 when the slice thickness or the number of bagged units of the sliced bread 14 is changed, for example, by performing a kind setting operation or the like, the approach from the back of the bread 14 is performed. It is preferable that the timing of starting the forward movement of the support members 27 with respect to the current position of the pushing member 22 can be changed. The support member 27 moves to the article passage entrance of the bag opening means 32 described later while supporting the front side of the bread 14. Further, as shown in FIG. 5, the transfer end of the supply conveyor 24 on which the bread 14 is placed and transferred is from the transfer end of the transfer conveyors 25, 25 to the lower holding member 34 close to the bag opening means 32. (Article passage entrance). In this embodiment, the holding conveyor is constituted by the supply conveyor 24 and a pair of transfer conveyors 25,25.
[0016]
Here, the position where the support members 27 and 27 can be sandwiched and held at the timing of starting the forward movement of the support members 27 and 27 is substantially the same as the overlap dimension of the bread pan 14 between the support members 27 and 27 and the push member 22. When the support members 27 and 27 and the pushing member 22 are positioned before and after sandwiching the bread 14 and transported in a holding state, the overlapping state of the bread 14 is disturbed and the transport distance is not difficult. If so, the position may be set to be larger than the overlapping dimension of the bread 14.
[0017]
As shown in FIG. 6, a bag mounting table 29 is provided downstream of the supply conveyor 24, and a number of bags 30 are provided on the mounting table 29 with their mouths directed toward the upstream in the article transfer direction. In the stacked state, the mouth side is pressed by the holding claw 31, and pressure air is blown toward the mouth from above the upstream side by an air blowing means (not shown) or the like, so that the uppermost portion of the stack is placed. The bag is configured to be opened.
[0018]
Between the supply conveyor 24 and the bag mounting table 29, bag opening means 32 for opening and holding the uppermost bag 30 mounted in a stacked state on the bag mounting table 29 moves forward and backward in the article transfer direction. It is arranged as possible. The bag opening means 32 includes four holding members 33, 33, 34, 34 arranged at positions corresponding to the four corners of the bread 14, and a pair of upper holding members 33, 33 located on the upper side, and a lower part. The downstream ends of the side holding members 34, 34 are configured to be movable toward and away from each other (see FIG. 1). Then, the downstream ends of the holding members 33, 33, 34, 34 move away while the holding members 33, 33, 34, 34 in the postures in which the downstream ends are close to each other move away from each other. At the timing after being inserted into the opened bag 30, as shown in FIG. 6, the opening of the bag 30 is held in a substantially rectangular shape through which the bread 14 can pass. Further, the pushing member 22 is configured to pass between the upper holding members 33, 33, and pushes the bread 14 from the upstream side toward the bag 30 opened by the bag opening means 32. I have.
[0019]

The side contact guide members 35 and 35 and the upper contact guide member 36 as contact guide means for elastically supporting the loaf of bread when the loaf of bread 14 passes therethrough are provided. That is, a plurality of (three in this embodiment) support plates 38 are disposed at predetermined intervals in the up-down direction with respect to the holder 37 on both sides in the width direction of the article transfer path in parallel with the article transfer path. A plurality (four in this embodiment) of side contact guide members 35 are disposed at predetermined intervals in the article transfer direction on the inner surface of the plate 38 on the article transfer path side. The side contact guide member 35 is made of a resin plate that can be elastically deformed without damaging the bread 14 when it comes into contact with the bread 14, and as shown in FIG. 3, the downstream end protrudes toward the article transfer path. The spacing between the projecting portions of the side contact guide members 35, 35 that are curved in the width direction and that face each other in the width direction is set to be smaller than the outer dimension of the bread 14. That is, the bread 14 passing between the contact guide members 35 on both sides is elastically supported on the front side by the guide members 35, 35 from both outer sides to prevent the overlapping state of the bread 14 from being disturbed. It is supposed to. The downstream end of the upstream side contact guide member 35 is positioned so as to partially overlap the upstream portion of the downstream side contact guide 35, and the front side of the bread pan 14 is arranged in the article transfer direction. Is configured to be continuously supported by the side contact guide member 35.
[0020]
The upper contact guide member 36 is rotatably supported at its upstream end with respect to a shaft portion 39 disposed above the article transfer path, and hangs down so as to be inclined downward toward the downstream side. The end is configured to be able to contact the upper edge of the bread 14 pushed by the pushing member 22. Further, the upper contact guide member 36 is always held in an inclined state by an elastic member such as a spring (not shown), and the upper contact portion 36 is elastically contacted with the upper edge portion of the bread pan 14 under the elasticity of the elastic member to disturb the overlapping state. Is to be prevented. The elasticity of the elastic member is set to a value that does not deform the bread 14. The upper contact guide member 36 is positioned at a position where it does not interfere with the pushing member 22.
[0021]
As shown in FIG. 6, an air nozzle 40 is provided above the downstream side of the bag mounting table 29 to blow pressure air from above to the bottom side of the bag 30 mounted on the bag mounting table 29. I have. After the bag 30 is opened by the bag opening means 32, pressurized air is blown from the air nozzle 40 toward the bottom of the bag, and the air nozzle 40 presses and deforms the bottom of the bag to deform the bag opening means 32. The inner surface of the bag is brought into contact with the front portion of the bread 14 that has passed through, so that the resistance causes the bread 14 to be pushed down to the bottom of the bag without falling forward. It is set that the blowing of the pressurized air from the air nozzle 40 is stopped at the timing when the pushing of the bread 14 into the bag bottom is completed.
[0022]
On the downstream side of the bag mounting table 29 (the bag filling position where the bread 14 is pushed into the bag 30), the packed bread 14 is supplied to the first feeding conveyor of the sealing device 45 before the sealing device 45. A delivery means 41 is provided at 48 (described later). As shown in FIG. 7, the transfer means 41 includes a connection conveyor 42 including a belt conveyor for placing the bagged bread 14 and transferring the bread to the downstream side, and both sides in the width direction of the connection conveyor 42 sandwiching the article transfer path. And a pair of holding conveyors 43, 43 for elastically holding and transporting the bread 14 together with the bag 30. In each holding conveyor 43, the belt surface of the endless belt 44 rotatably wound between a pair of pulleys separated in the article transfer direction is arranged in a posture orthogonal to the article transfer surface of the connection conveyor 42, and A large number of elastic bodies made of sponge are disposed on the belt surface. Note that the article transfer speed of the connection conveyor 42 and the holding conveyors 43, 43 is set to a speed synchronized with the article pushing speed of the pushing conveyor 23, and the motors (see FIG. 1) provided in each of the conveyors 42, 43, 43, respectively. (Not shown).
[0023]
The transfer end of the transfer means 41 extends to the downstream side from the push end of the push conveyor 23, and while the packed bread 14 is transferred by the transfer means 41, the push member 22 It is configured to retreat from the mouth of the bag 30 by rotating so as to move away from the bread 14 to the upstream side in the article transfer direction with the attachment portion to the endless chain 21 as a fulcrum. Also, as shown in FIG. 1, the article transfer surface of the connection conveyor 42 on which the bread 14 is placed is set so as to be inclined downward toward the downstream side in the article transfer direction, and the pushing of the pushing conveyor 23 is released. The subsequent bread 14 is transported in a state where it is supported by the bottom of the bag, whereby the posture can be prevented from being distorted by leaning backward toward the mouth of the bag 30. It is sufficient that the transfer end portion of the transfer means 41 extends at least to the pushing end portion of the pushing conveyor 23. The sealing device 45 is provided in a state where the packed bread 14 is supported by the pushing member 22 on the rear side. May be passed to the user.
[0024]
As shown in FIG. 1, the sealing device 45 connected to the downstream side of the delivery means 41 faces up and down with the transfer path of the packed bread 14 therebetween. A pair of upper and lower seals 46 and 47 for heat sealing the sides, a first feed conveyor 48 located upstream and a second feed conveyor 49 located downstream with respect to the sealing position by the seals 46 and 47. Basically, the operating mechanisms and operations of the seal bodies 46 and 47 and the double feed conveyors 48 and 49 are, for example, the mechanisms and operations described in detail in Japanese Patent Application Laid-Open No. 2002-193203 filed by the present applicant. Can be adopted. An article guide means 50 similar to that described in detail in Japanese Patent Application Laid-Open No. 2002-193203 is disposed above the first feed conveyor 48, and the posture and transfer of the bread 14 packed in a bag by the article guide means 50. The position is maintained constant and guided to the sealing position.
[0025]
The article transfer surface of the two conveyors 48 and 49 on which the bread 14 is placed is inclined at the same angle as the article transfer surface of the connection conveyor 42 of the transfer means 41 toward the downstream side in the article transfer direction. It is configured to prevent the bread loaf 14 being set and transferred to the sealing position from being disturbed in the overlapping state. In addition, the height position of the downstream end of the connection conveyor 42 and the upstream end of the first feed conveyor 48 is determined so that the bagged bread 14 can be smoothly delivered.
[0026]
As shown in FIG. 8, an unloading conveyor 51 whose article transfer direction is orthogonal is connected to the downstream side of the second feed conveyor 49 positioned downstream of the sealing device 45, and is transferred to the unloading conveyor 51 and transferred in the transfer direction. The mouth side of the bag 30 in which the bread 14 converted by 90 ° is stored is bound by a binding device 52 disposed on one side of the conveyor 51.
[0027]
Operation of the embodiment
Next, the operation of the article transfer device according to the above-described embodiment will be described. As shown in FIGS. 2 and 8, the bread 14 is pushed by the transport conveyor 12 and transferred to the transfer conveyor 16 in a posture in which the overlapping direction is orthogonal to the article transport direction. The bread 14 is transported to a position where it comes into contact with the stopper 18 while being guided by the side guides 19 and 20. At this time, the support members 27, 27 located on the upstream side in the article transfer direction of the transfer conveyors 25, 25 face forward in the article transfer direction of the bread 14 delivered to the transfer conveyor 16, and The sliced bread is supported by the front part where the sliced surface is facing so that the sliced bread does not fall.
[0028]
At a predetermined timing after the bread 14 reaches the transfer end of the transfer conveyor 16, the pushing member 22 of the pushing conveyor 23 moves forward in a direction orthogonal to the transfer direction of the transfer conveyor 16 and the bread 14 At the timing when the pushing member 22 comes to a position where the pushing member 22 can sandwich and hold the bread 14 back and forth between the supporting members 27 and 27, the servomotors 28 and 28 of the transfer conveyors 25 and 25 are driven to rotate. By starting the forward movement of the support members 27, 27, the bread 14 is held back and forth by the support members 27, 27 and the pushing member 22 so that the overlapping direction thereof is along the article transfer direction. The bread 14 is placed on the supply conveyor 24 while its side is guided by the stopper 18, and is transferred to the article passage entrance of the bag opening means 32. . That is, before and after the loaf of bread 14 transported in a posture in which the overlapping direction is along the article transport direction, since the supporting members 27, 27 and the pushing member 22 support the slice bread, each slice pan is located on the front side or the rear side in the article transport direction. The overlapping state is not disturbed by leaning on. Further, since the supply conveyor 25 and the transfer conveyors 25, 25 move at a speed synchronized with the pushing speed of the pushing member 22, the outer edge of the bread 14 does not rub, and the bread 14 is not damaged. Absent. In addition, since the forward movement start timing of the support member 27 in the transfer conveyor 25 driven by the servomotor 28 is configured to be variable, even when the overlap size changes according to the number of stacked breads 14 or the like, it is easy.
