Description

【０００１】
【発明の属する技術分野】
この発明は、ダンボール箱に装填されている内袋の閉鎖装置に関するものである。
【０００２】
【従来技術】
ダンボール箱内に装填されている内袋に柿を詰めて、ドライアイス及びアルコールを入れて密閉閉鎖し、所定期間冷蔵保存して柿の渋を抜く方法がある。その際に、内袋を密閉閉鎖する方法として、柿の詰められた内袋の上部開口部を保持装置で握持し、ダンボール箱を支持している支持台を縦軸回りに回転して内袋の上部開口部を捩じり、この捩じり部を輪ゴム等で止めて密閉閉鎖する方法が取られていた。
【０００３】
【発明が解決しようとする課題】
前記のように、内袋の上部開口部を捩じり密閉閉鎖方法にあっては、柿の渋抜きが適正にできているか否かを点検する際には、上部開口部を捩じり戻して内袋を開口して、柿の渋抜き状態を点検し、点検作業が終了すると、内袋の上部開口部を再度捩じり閉鎖しなければならず、手数を要し点検作業が煩雑になるという問題点があった。
【０００４】
そこで、このような問題点を解消しようとするものである。
【０００５】
【課題を解決するための手段】
このような技術的課題を解決するために、この発明は次のように構成した。即ち、内壁に内袋（２２）を沿わせたダンボール箱（２１）を搬送する第一コンベヤ（２７）と、第一コンベヤ（２７）の搬送終端部の側方隣接位置を搬送始端部とする第二コンベヤ（２７ａ）とを設け、第一コンベヤ（２７）の搬送終端部をダンボール箱（２１）の停止第１位置（３０）とし、第二コンベヤ（２７ａ）の搬送始端部をダンボール箱（２１）の停止第２位置（３５）とし、停止第１位置（３０）の上方には、内袋（２２）の開口部を吸着して持ち上げる前・後吸着装置（３１，３１）と、内袋（２２）の上端開口部を前後方向に広げる前・後脱気パイプ（３２，３２）と、脱気パイプ（３２，３２）で前後方向に広げた内袋（２２）の上端開口部を偏平整形するスポンジローラー（３３，３３）を両端部に有する左・右ローラーアーム（３４，３４）と、を設け、停止第１位置（３０）の側方には、停止第１位置（３０）にあるダンボール箱（２１）を第二コンベヤ（２７ａ）の停止第２位置（３５）に移動させる位置移動シリンダ（３６）を設け、停止第２位置（３５）の前後側方には、内袋（２２）の上部開口部を巻き付け折り畳んで偏平整形部（２２ａ）を形成する前・後チャック（３７，３７）を設け、停止第２位置（３５）の上方には、内袋（２２）の前記偏平整形部（２２ａ）の前後両端部を折り畳む折り曲げ装置（３８）と、ダンボール箱（２１）の水平開口状態の前・後フラップ（２１ａ，２１ｂ）を折戻す前・後折戻し装置（３９，３９）を設け、スポンジローラー（３３，３３）で内袋（２２）の上端開口部を挟んだままで、停止第１位置（３０）にあるダンボール箱（２１）を位置移動シリンダ（３６）の伸長により左右方向に押し動かし停止第２位置（３５）に移動させ、次いで、前・後チャック（３７，３７）を内側に移動し、内袋（２２）の偏平整形部（２２ａ）の先端両側位置を前・後チャック（３７，３７）の挾み片（３７ｄ，３７ｄ）で挾み、チャック回転手段（３７ｂ）により前・後チャック（３７，３７）の挾み片（３７ｄ，３７ｄ）を回転させながら、偏平整形部（２２ａ）の基部側に移動し、偏平整形部（２２ａ）を巻き付けて内袋（２２）密閉し、折り曲げ装置（３８）が降下して偏平整形部（２２ａ）の両側部を押さえ、次いで、ダンボール箱（２１）の前・後フラップ（２１ａ，２１ｂ）を前・後折戻し装置（３９，３９）により折り返す構成としたことを特徴とするダンボール箱の内袋の閉鎖装置である。
【０００６】
【発明の作用及び効果】
第一コンベヤ２７の搬送終端部の停止第１位置３０にダンボール箱２１が搬送されると、前・後吸着装置３１，３１が内袋２２の開口部を吸着して持ち上げ、前・後脱気パイプ３２，３２が内袋２２の上端開口部を前後方向に広げる。
【０００７】
そして、内袋２２の左右両側を接近させ、且つ、起立状態にある前・後フラップ２１ａ，２１ｂを水平方向に折り曲げながら、偏平整形部２２ａを形成する。
【０００８】
次いで、図８の（４）に示すように、スポンジローラー３３を先端に支持している左・右ローラーアーム３４，３４を前後両側方から回動降下して、左右のスポンジローラー３３，３３で内袋２２の偏平整形部２２ａを絞り込み下端部を挟持すると共に、前・後脱気パイプ３２，３２により吸気し内袋２２内の空気を脱気をする。
【０００９】
次いで、スポンジローラー（３３，３３）で内袋（２２）の上端開口部を挟んだままで、停止第１位置（３０）にあるダンボール箱（２１）を位置移動シリンダ（３６）の伸長により左右方向に押し動かし停止第２位置（３５）に移動させ、次いで、前・後チャック（３７，３７）を内側に移動し、内袋（２２）の偏平整形部（２２ａ）の先端両側位置を前・後チャック（３７，３７）の挾み片（３７ｄ，３７ｄ）で挾み、チャック回転手段（３７ｂ）により前・後チャック（３７，３７）の挾み片（３７ｄ，３７ｄ）を回転させながら、偏平整形部（２２ａ）の基部側に移動し、偏平整形部（２２ａ）を巻き付けて内袋（２２）密閉し、折り曲げ装置（３８）が降下して偏平整形部（２２ａ）の両側部を押さえ、次いで、ダンボール箱（２１）の前・後フラップ（２１ａ，２１ｂ）を前・後折戻し装置（３９，３９）により折り返して、前記偏平整形部２２ａを前・後フラップ２１ａ，２１ｂで押圧保持する。
【００１０】
前記のようにするので、ダンボール箱２１内に装填した内袋２２内の空気を円滑に脱気し、脱気後の空気の内袋２２内への逆流を確実に防止できる。また、ダンボール箱２１に装填した内袋２２における上部開口部の偏平整形部２２ａを前・後チャック３７，３７により安定した状態で巻き付け折り畳み内袋２２を確実に密閉閉鎖できる。
【００１１】
【発明の実施の形態】
図１乃至図３に基づき、柿選別施設の一実施例の形態について説明する。図１には、柿選別施設における１階の荷受部１及び出荷部２の平面図が図示されている。
【００１２】
荷受部１の第１荷受コンベヤ３には、柿の入れられた複数のカゴが載置されているパレット（図示省略）が供給載置される構成である。供給載置されたカゴは分配供給装置４により、一個ずつ第２荷受コンベヤ５に載せ換えられて順次移送され、第２荷受コンベヤ５の終端部から更に第３荷受コンベヤ６及び第４荷受コンベヤ７に順次載せ換えられて終端側に移送され、リフト装置８により２階の選別箱詰め部９に揚上移送される構成である。
【００１３】
また、１階の荷受部１の側方には、出荷部２が併設されている。２階の選別箱詰め部９で柿は選別され、選別済の柿の詰められたダンボール箱は、２階の排出コンベヤ１０に載せられて１階まで移送されて、１階の出荷コンベヤ１１に引き継がれる。出荷コンベヤ１１で移送中のダンボール箱の側面には品質区分が側面に印字されていて、センサ（図示省略）により印字品質区分が検出されて、分配装置で各品質毎に分配され、各品質毎に纏めて最終出荷コンベヤ１２，１２，…に取り出される構成である。
【００１４】
図２には、柿選別施設の２階の選別箱詰め部９の平面図が図示されている。この選別箱詰め部９には３系列の選別箱詰めラインが設けられている。１階のリフト装置８により揚上搬送されたカゴは、反転しながら内部の柿が分配コンベヤ１４に移し換えられて、第１選別コンベヤ１５に引継がれる。第１選別コンベヤ１５の移送中において、人手により例えば傷の有無等を基準にして、４つの階級に選別され、夫れ夫れの階級毎に分けて第２選別コンベヤ１６，１６，…に置き換え一次選別さられる。
【００１５】
次いで、第２選別コンベヤ１６，１６，…を移送される途中において、カメラ（図示省略）により例えば形状及び色彩が撮像されて、制御部（図示省略）において基準データと比較することにより複数の等級に判別し、階級毎に一次選別された柿を更に等級別に二次選別する。しかして、第２選別コンベヤ１６の移送中に制御部から等級に応じた排出指令を出して、夫れ夫れの品質毎に対応する最終選別コンベヤ１６ａ，１６ａ，…に柿を排出選別する。
【００１６】
図３には、２階の上方に構成されているダンボール箱２１の組立て、次いで、内袋２２をダンボール箱２１に装着し、次いで、移送供給する箱供給部１７の平面図が図示されている。まず、箱組立て装置１８により、折り畳み状態の素材からダンボール箱２１を組立て、前・後，左・右のフラップ２１ａ，２１ｂ，２１ｃ，２１ｄを起立し、ダンボール箱２１を開口した状態とする。次いで、このようにして組み立てたダンボール箱２１を箱移送コンベヤ１９により送り出す。
【００１７】
次いで、内袋挿入装置２０でポリ袋により構成されている内袋２２をダンボール箱２１の開口部から内部に装着する。次いで、ダンボール箱２１は箱移送第２コンベヤ１９ａに引き継ぎ移送されて、中２階から２階に移送され、更に、箱移送第３コンベヤ１９ｂに引き継がれて、３系列の選別箱詰め部９の第２選別コンベヤ１６，１６，…の下方に分配移送される。
【００１８】
前記のようにして最終選別コンベヤ１６ａ，１６ａ，…に品質毎に分けて取り出された柿は、例えば、人手によりダンボール箱２１内の内袋２２に所定重量ずつ詰められる。次いで、柿の詰められたダンボール箱２１は、前記第２選別コンベヤ１６，１６，…の下方に設けられている製品コンベヤ２３，２３，…に載せられ移送される。製品コンベヤ２３により移送中のダンボール箱２１側面には、品質内容を印字装置（図示省略）により印字され、終端側に移送される。
【００１９】
製品コンベヤ２３，２３，…の終端に送られたダンボール箱２１は、密閉部２４に送られる。この密閉部２４には、柿の詰められた内袋２２をダンボール箱２１に入れた状態で送られてくる。ここでは、先ず、柿の渋を抜くために、ドライアイス及びアルコールを内袋２２に人手あるいは装置により自動的に所定量投入され、次いで、内袋２２の上部を巻き付けて脱気しつつ密閉し、次いで、前・後フラップ２１ａ，２１ｂを押し付け閉鎖し、前・後フラップ２１ａ，２１ｂの上面に糊を塗布する。
【００２０】
次いで、ダンボール箱２１は製品コンベヤ２１，２３，…により封緘部２５に移送される。封緘部２５では、先ず、左・右フラップ２１ｃ，２１ｄを前・後フラップ２１ａ，２１ｂ上に左右両側から押し付けて閉鎖して、全フラップ２１ａ，２１ｂ，２１ｃ，２１ｄを糊で接着閉鎖し、次いで、止め金具により封緘する。このように封緘されたダンボール箱２１は、保管倉庫２６に送られて品質毎に保管される。
【００２１】
次ぎに、図４乃至図１２に基づき内袋２２の脱気、内袋２２の閉鎖及びダンボール箱２１のフラップの封緘構成について説明する。内袋２２の開口部を密閉する密閉部２４は、図４に示すように、次ぎのように構成されている。密閉部２４には、ローラーコンベヤからなる密閉第１コンベヤ２７及び密閉第２コンベヤ２７ａが設けられていて、ダンボール箱２１の内袋２２に柿が詰められた状態で、密閉第１コンベヤ２７の始端部に送られてくる。すると、ダンボール箱２１は密閉第１コンベヤ２７上をガイド２８に沿って終端側に移動し、停止片２９に規制されて停止第１位置３０に停止する。
【００２２】
図５，図６及び図８に示すように、停止第１位置３０の上方には、内袋２２の開口部を吸着して持ち上げることのできる前・後吸着装置３１，３１、（図８の１に図示）、上下移動及び左右移動のできる縦方向に沿った前・後脱気パイプ３２，３２、及び、内袋２２の開口部を偏平整形するスポンジローラー３３を両端部に有する左・右ローラーアーム３４，３４が、設けられている。
【００２３】
停止第１位置３０の側方には、停止第１位置３０にあるダンボール箱２１を密閉第２コンベヤ２７ａの始端側位置の停止第２位置３５に移動させる位置移動シリンダ３６が設けられている。前記停止第２位置３５の前後側方には、内袋２２の上部開口部を巻き付け折り畳んで偏平整形部２２ａを形成する前・後チャック３７，３７が設けられており、また、停止第２位置３５の上方には、内袋２２の前記偏平整形部２２ａの前後両端部を折り畳む折り曲げ装置３８（図８の７に図示）、及び、ダンボール箱２１の水平開口状態の前・後フラップ２１ａ，２１ｂを折戻す前・後折戻し装置３９，３９が設けられている。
【００２４】
なお、前記前・後チャック３７は、図７に示すように、次ぎのように構成されている。チャック回転軸３７ａ、チャック回転軸３７ａを回転駆動するチャック回転手段３７ｂ、チャック回転軸３７ａの先端部に嵌合支持されていて一体的に回転し、且つ、長手方向にも移動できる筒体３７ｃ、筒体３７ｃに回動自在に軸支されていて内袋２２の開口部を挟持することのできる一対の挾み片３７ｄ，３７ｄ、一対の挾み片３７ｄ，３７ｄを開閉するチャック開閉装置３７ｅ（バネ、リンク，筒体，シリンダ等により構成）、前・後チャック３７，３７を左右方向に移動させるシリンダ等からなる左右移動装置３７ｆ等により、構成されている。
【００２５】
次ぎに、図５乃至図１２に基づき、制御部の指令により内袋２２の開口部を密閉して偏平整形し、次いで、ダンボール箱２１のフラップを閉鎖する行程について説明する。密閉部２４には、図８（１）に示すような状態でダンボール箱２１は送られてくる。即ち、ダンボール箱２１の内壁に内袋２２を沿わせた状態で装着し、内袋２２の開口上部を起立状態のフラップ内面に沿わせ、かつ、開口上端部を下方に折り返し、前後・左右のフラップ２１ａ，２１ｂ，２１ｃ，２１ｄを包み込んだ状態として、ダンボール箱２１は送られてくる。
【００２６】
しかして、先ず初めに、前・後脱気パイプ３２，３２が下方に移動して、前・後脱気パイプ３２，３２の先端部がダンボール箱２１の起立状態の前・後フラップ２１ａ，２１ｂの近傍で、且つ、左右方向中間部位置に移動する。次いで、前・後吸着装置３１，３１（なお、前吸着装置３１は図示省略）が下降し、外側吸着部３１ａで内袋２２の開口上端部外側面を吸着保持し、次いで、上方に移動して開口上端部を引き上げ、次いで、内側吸着部３１ｂが回動して開口上端部を吸着保持し、両吸着部で引き上げ、図８（２）に示すように、起立状態のフラップの内側近傍に沿わせて、内袋２２の開口部を起立状態とする。
【００２７】
次いで、図８（３）及び図９に示すように、前・後脱気パイプ３２を前後方向に互いに遠ざかる方向で、且つ、下方に順次移動させる。即ち、前脱気パイプ３２を矢印に示すように、前側斜め下方に移動させ、後脱気パイプ３２を後側斜め下方に移動させる。すると、前・後脱気パイプ３２，３２により内袋２２の上端開口部を前後に広げて前後の開口部が互いに接近する状態となり、偏平整形部２２ａが形成され、且つ、前・後フラップ２１ａ，２１ｂを押し倒し、水平状態に広げる。
【００２８】
なお、前・後脱気パイプ３２，３２の移動装置は、図９に示すように次のように構成されている。ガイド柱４４，４４に脱気パイプ支持体４５を上下動自在に支持し、脱気パイプ支持体４５の前・後スプロケット４６，４６にチエン４７を巻き掛け、また、脱気パイプ支持体４５のチエン４７の側方には前後方向に沿わせてパイプ支持棒４８を設けて、このパイプ支持棒４８に前・後脱気パイプ３２，３２の支持部３２ａ，３２ａを嵌合して移動自在に支持し、支持部３２ａ，３２ａの一方をチエン４７の上側部分に係合し、他方をチエン４７の下側部分に係合している。また、脱気パイプ支持体４５は上下シリンダ５０，５０により、ガイド柱４４，４４に沿って上下動する構成である。
【００２９】
従って、前・後脱気パイプ３２，３２が前後方向に近接し且つ上方に位置した状態で、モータ４９を正転駆動すると、前・後脱気パイプ３２，３２はチエン４７により互いに遠ざかりながら前後に移動し、これと同時に、上下シリンダ５０，５０で脱気パイプ支持体４５を下動させることにより、前・後脱気パイプ３２，３２を前記のように移動させるものである。
【００３０】
しかして、内袋２２の脱気及び偏平整形、並びに、ダンボール箱２１の前・後フラップ２１ａ，２１ｂの水平状態への折り曲げを円滑に行ない、内袋２２内の脱気を十分行なうことができる。図８の（３）に示すように、前・後脱気パイプ３２，３２により内袋２２の偏平整形すると共に、前・後フラップ２１ａ，２１ｂを水平状態に折り曲げると、次いで、図８の（４）及び図１０に示すように、スポンジローラー３３を先端及び基部に回転自在に支持した左・右ローラーアーム３４，３４が、左右両方から回動降下して、先端のスポンジローラー３３，３３で内袋２２の偏平整形部２２ａの下端を、絞り込んで挟持する。
【００３１】
なお、この動きと並行して、吸気ポンプ（図示省略）を作動し、前・後脱気パイプ３２，３２により吸気し内袋２２内の脱気をする。しかして、内袋２２内の脱気を円滑にし、脱気後の空気の逆流を確実に防止できる。
【００３２】
図８の（４）の前記状態から、図５，図１１及び図１２に示すように、先端のスポンジローラー３３，３３で挟んだままで、停止第１位置３０にあるダンボール箱２１を位置移動シリンダ３６の伸長により箱押し装置４２により、左右方向に押し動かし停止第２位置３５に移動させる。次いで、前・後チャック３７，３７を内側に移動し、内袋２２の偏平整形部２２ａの先端両側位置に対応させる。
【００３３】
なお、このときに、図５，図１１及び図１２に示すように、上側に位置している左・右ローラーアーム３４，３４の基部側の回転自在のスポンジローラー３３、及び、フレームに回転自在に支持されている案内ローラー４３と、下側に位置している箱押し装置４２の上面部４２ａとの間に、左・右フラップ２１ｃ，２１ｄ及び内袋２２の偏平整形部２２ａ上面が押圧規制されつつ通過し、密閉第２コンベヤ２７ａのある停止第２位置３５に送られ、内袋２２上部の偏平整形部２２ａの先端が前・後チャック３７，３７に対応位置する。
【００３４】
次いで、前・後チャック３７，３７が前後方向に互いに接近方向に移動して、挾み片３７ｄ，３７ｄにより偏平整形部２２ａの先端部両側を挾み（なお、図１２に示すように、前・後チャック３７，３７の下側の挾み片３７ｄは、箱押し装置４２における上面部４２ａの切欠き部４２ｂを通過して上方に移動して挾む。）、チャック回転手段３７ｂにより前・後チャック３７，３７の挾み片３７ｄ，３７ｄを時計回りに回転させながら、偏平整形部２２ａの基部側に移動し、偏平整形部２２ａを巻き付けて密閉する。
【００３５】
しかして、内袋２２の偏平整形部２２ａを安定した状態で巻き付け折り畳みすることができる。次いで、図８の（７）に示すように、逆Ｕ字形の折り曲げ装置３８が降下して偏平整形部２２ａの両側部を押さえ、次いで、図８の（８）に示すように、水平状態の前・後フラップ２１ａ，２１ｂを前・後折戻し装置３９，３９により折り返して、偏平整形部２２ａを前・後フラップ２１ａ，２１ｂにより押圧保持する。
【００３６】
次いで、人手あるいは自動的に前・後フラップ２１ａ，２１ｂの上面に糊付けをし、起立状態の左・右フラップ２１ｃ，２１ｄを折り返し、全フラップの仮止めをして、ダンボール箱２１を次ぎ封緘行程に移送する。
