Description
前記ガイドロールとして、前記入口ロールと、前記出口ロールと、前記出口ロールの下方に配置された出口側下部ロールと、前記入口ロールの下方に配置された入口側下部ロールと、をそなえ、前記搬送ベルトは、前記入口ロール及び前記出口ロールに案内されて前記入口側から前記出口側へと移動しながら前記段ボールシートを搬送し、前記段ボールシートの搬送後、前記出口側下部ロール及び前記入口側下部ロールに案内されて前記出口側から前記入口側へと戻るように循環し、前記区画室は、前記出口ロールから前記出口側下部ロール及び前記入口側下部ロールを経て前記入口ロールに進行する間の前記搬送ベルトの循環経路内に配設されていることが好ましい。
前記区画室は、前記入口ロールの直上流に配置され、前記仕切部材と前記搬送ベルトの前記裏面と前記入口ロールの外周面とにより、若しくは、前記仕切部材と前記搬送ベルトの前記裏面と前記入口ロールの前記外周面と前記サクションボックスの壁面とにより、区画形成されていることが好ましい。
前記空気流通手段には、前記サクションボックスの負圧が利用されることが好ましい。

図1~図5は本発明の一実施形態を説明するもので、これらを用いて実施形態にかかる搬送コンベア及びこの搬送コンベアをそなえた印刷装置及びこの印刷装置をそなえた製函機について説明する。
まず、本実施形態にかかる製函機について図2を参照して説明する。
図2では、段ボールシートが製函用シート材に加工される工程を装置構成の上方に装置構成とは分けて示している。図2に示すように、この製函機は、上流側から、給紙部1,印刷部2,排紙部3,ダイカット部4,フォルダグルア部5,カウンタエジェクタ部6が順に設けられている。
給紙部1では、板状の段ボールシート10aが多数積載された状態で搬入され、この段ボールシート10aを1枚ずつ印刷部2に供給する。
排紙部3及びダイカット部4では、印刷部2で印刷された段ボールシート10aに、溝切りや罫線入れを行なう。
なお、ダイカット部4では、特殊な形状の箱を作成するための溝切り,罫線入れを行なうこともある。したがって、排紙部3及びダイカット部4のどちらも溝切り,罫線入れを行なう機能を有している。
カウンタエジェクタ部6では、フォルダグルア部5で加工された製函用シート材10を計数しながら、スタッカに積載する。そして、所定枚数の製函用シート材10が積み上げられたら、このシート材群100を1単位として出荷する。
なお、排紙部3を有さず、ダイカット部4において、手穴,空気穴等の孔開け及び打ち抜きを行なうと共に、上記の特殊な形状の箱を作成するための溝切り,罫線入れを行なって、印刷及び溝切りや罫線入れをされた段ボールシート10aを製品の製造ラインに導入して、段ボールシート10aの上に物品を集積して載せ、これを包み込むようにしながら箱を成形して包装する、ラップアラウンド・ケーサーとも呼ばれる機械もある。このような機械に提供する製函用シート材は、ダイカット部4で処理した段階の印刷及び溝切りや罫線入れをされた段ボールシート10aであり、この場合、製函機は、フォルダグルア部5が省略され、ダイカット部4で処理した段ボールシート10aをカウンタエジェクタ部6に送って処理して出荷するものとなる。本発明はこうした製函機にも適用することができる。
次に、製函機の印刷部2に適用される搬送コンベア20及びこれをそなえた印刷装置について説明する。
図3に示すように、印刷部2には、搬送ベルト23を有する搬送コンベア20と、搬送コンベア20によって1枚ずつ搬送される段ボールシート10aに、各色のインキを順次印刷する印刷ユニット2a~2dとがそなえられる。
搬送コンベア20は、搬送ベルト23と、この搬送ベルト23を案内、又は案内及び駆動するガイドロール25a,25b,26a,26b,27a~27eと、段ボールシート10aの搬送経路に対して搬送ベルト23を挟んで配設されたサクションボックス24a~24dとをそなえている。
搬送ベルト23は、ゴムシートに布シートを積層させて柔軟で且つ延びのない材料特性を有すると共に多数の細孔が形成され表裏間で通気性を有する無端状のベルトである。この搬送ベルト23は、ガイドロール25a~27bで案内された軌道上を循環しながら段ボールシート10aを搬送する。
さらに、この出口側下部ロール27aと、これに隣接する下部ロール27cとの間のガイドロール27bは、図3中に矢印で示すように、下部ロール27a,27cに対して接近又は離隔する方向に可動であって、軸心位置を変更することによりベルト全体のテンションを調整できるようにするベルトテンション調整ロールとして機能する。
入口ロール25aから出口ロール26aにかけて走行する搬送ベルト23の上面(表面)23aの搬送面に載った段ボールシート10aは、これらのサクションボックス24a~24d内の負圧によって、搬送ベルト23の搬送面23aに吸着されながら、搬送方向に位置ずれを起こすことなく搬送される。
ダクト30は、このダクトカバー31の内面31aと、入口ロール25aの直下を通過する搬送ベルト23の裏面23bと、入口ロール25aの外周面25fと、最上流のサクションボックス24aの壁面24wとにより包囲され、区画形成されている。
本実施形態においては、入口ロール25aの近傍の多数の部材の表面を利用することにより、ダクトカバー31の横断面の形状サイズを抑えながら、ダクト30の断面積を確保することができる。
空気供給部41aは、エアブロア42と、ダクトカバー31の一端を塞ぐように接続されてダクト入口32aにエアブロア42の吹出口が接続された空気供給ダクト32とをそなえる。空気排出部41bは、サクションブロア43と、ダクトカバー31の他端を塞ぐように接続されてダクト出口33aにサクションブロア43の吸込口が接続された空気排出ダクト33とをそなえる。
また、図1,図4に示すように、本搬送コンベア20の入口部の上方には、即ち、入口ロール25aと対向する対向ロール25bに隣接して(ここでは、対向ロール25bよりもシート搬送方向上流側)には、対向ロール25bから送り出された段ボールシート10aに付着している紙粉を吸引除去するシート紙粉除去装置の紙粉吸引ダクト40の吸引口が配設されている。この紙粉吸引ダクト40は、図1,図4に二点鎖線で示すように、対向ロール25bよりもシート搬送方向下流側に配置してもよい。
なお、エアブロー装置41の空気排出部41bの下流及び紙粉吸引ダクト40の下流は、図2に示す接続ダクト7eを介して製函機の上部の吸引ダクト7Hに接続され、吸引した紙粉は、吸引ダクト7Hを経て集塵部7Gに集塵されるようになっている。
本発明の一実施形態にかかる搬送コンベア及びこれをそなえた印刷装置、更にこの印刷装置を印刷部としてそなえた製函機は、上述のように構成されているので、以下のような作用及び効果を得ることができる。
特に、本実施形態では、ダクト30が搬送コンベア20の入口ロール25aとサクションボックス24aとの間の紙粉が溜まる箇所に設定されるので、この箇所の紙粉を効果的に除去することができる。
さらに、搬送ベルト23の搬送面23aの上方に、搬送される段ボールシート10aから付着した紙粉を吸引除去するシート紙粉除去装置をそなえるので、サクションボックス24a~24dによって吸引され搬送ベルト23の裏面23bに付着する紙粉を減少させることができる。
以上、本発明の実施形態について説明したが、本発明は上述の実施形態のものに限定されず、本発明の趣旨を逸脱しない範囲で、適宜変形或いは省略或いは組み合わせをして実施することができる。
図6(a),図6(b)に示すものは、ダクト30の両端に空気供給部41aを設け、ダクトカバー31に単数又は複数の排出孔31bを形成して空気排出部41bを構成する。ダクト30の両端から取り入れられたエアはダクトカバー31の排出孔31bから排出される。
また、空気供給部41aあるいは空気排出部41bに、図8に示すようなエアガン60を利用してもよい。
これにより、搬送ベルト23と異なる極性のために電気的吸着力によって搬送ベルト23の裏面23bに付着した紙粉も、より強く帯電された流通空気に吸い寄せられ、搬送ベルト23の裏面23bから除去される。
つまり、搬送ベルト23の裏面23bに付着した紙粉を除去するという観点から、搬送ベルト23が出口ロール26aから出口側下部ロール27a及び入口側下部ロール27eを経て入口ロール25aに進行する間の搬送ベルト23の循環経路内であれば特に配置箇所は限定されない。すなわち、出口ロールから入口ロールに進行する箇所の搬送ベルトの裏面側であれば、何れの箇所にダクト30を配置してもよい。この部分は、サクションボックス24がなくスペースを比較的確保しやすく、搬送ベルト23の裏面23bも露出するので、この箇所にダクト30を設ければレイアウト上有利であり、紙粉の除去にも有効である。
