- the structure of the second pusher 150 is the same as that of the first pusher 130, and the second pusher 150 is transported with the same pusher until it reaches the fourth cutting machine 16, or while taking over at a midway position.
- FIG. 7 is an explanatory diagram of the lower side cutting step S10 and the small block dividing step S12. Since the lower side 103a is a part of the lower side 103, the end portions thereof are not uniform as described above, but the surplus portion 109 is cut by a circled line 6 in FIG.
- the fourth cutting machine 16 cuts the row unit block 107 advanced by the second pusher 150 while the cutting blade moves up and down.
- the lower side exclusion means excludes the surplus portion 109 after the lower side cutting. Similar to the right side exclusion means, it has a structure in which it is removed immediately after the cutting blade of the fourth cutting machine 16. A butterfly mechanism which is opened upward or downward only when the surplus portion 109 is dropped downward and is normally closed horizontally is provided, and the opening / closing control is performed in accordance with the pushing and conveying of the second pusher 150.

(第1実施例)
図1は、本発明の第1実施例に係る断裁装置10の全体説明図である。本発明は例えば100枚単位の大判シートブロックから紙幣、宝くじ、葉書、有価証券のような比較的小さな用紙サイズの小ブロックに断裁するための装置である。本発明の対象としてはこれらに限定されないが、断裁後の用紙サイズに高い精度が要求される断裁装置に適する。
本実施例では、まず突き揃え機11において大判シート100の基準辺を揃える。突き揃え機11の構成は公知であるので図示を省略するが、例えば特許文献4に記載されるように、グリッパーが積載ブロックを所要量引き出して積載ブロックの前端面を前当てに突き当て、積載ブロックのクランプを開放する。この状態で、尻たたきが下方から流体圧シリンダーによって積載ブロックの後端面に対向する位置まで上昇する。そして、尻たたきは、シリンダーによって、積載ブロックの後端面を前当てに向かって繰り返したたくことにより、積載ブロックの前端面を前当てに突き揃える。
第1搬送機13において、断裁された大判シートブロックの左辺を右辺方向に向かって押し搬送する。第1搬送機13には例えば4つの第1プッシャー130が備えられており、該第1プッシャー130は図3(a)のように大判シートブロックの左辺104を押し搬送する。
図3(b)に示すように突き揃えられた左辺104を第1プッシャー130で押すと大判シート100にはズレがほとんど生じない。一方、図3(c)に示すように突き揃えられていない辺、例えば右辺102を第1プッシャー130が押すと、不揃いな端部に合わせて各シートにズレが生じてしまう。
主プッシャー132は上下作動機構により送り開始位置において上方回動して大判シート100の左辺と対向し、一次送りが完了するまでこの状態を保持し、更に主プッシャー132は中途位置において下方回動し、大判シート100の左辺から離れて送り開始位置に向かい復帰する。
次に、第2断裁機14が、第1プッシュ工程S3の後で大判シートブロック100の右辺102を断裁する。図6は右辺断裁工程S4及び列単位分割工程S6の説明図である。
右辺102は上述した通り端部が不揃いであるが、図6の丸数字1の線で余り部分106を断裁する。第2断裁機14は断裁刃140が上下運動しながら第1プッシャー130で前進する大判シートブロック100を断裁する。
右辺排除手段が、右辺断裁後の余り部分106を排除する。余り部分106は大判シート100の全幅の長さの細長い紙束であるので、右辺排除手段は断裁刃140の直後方でこれを取り除く構造を有する。例えば、搬送レール131の一部に細長の開口部を設けておき、バタフライ機構にとってこの開口部を開閉する。
すなわち、余り部分を下に落とす際だけ上向き又は下向きに開放し、通常は水平に閉じた状態のバタフライ機構を設け、第1プッシャー130の押し搬送に合わせて開閉制御する。
第2断裁機14が、第1プッシャー130の押し搬送と相互動作しながら大判シートブロック100の右端を順次断裁して上下方向に長尺な列単位ブロック107に分割する。上記の通り本実施例では主プッシャー132と従プッシャー133が交互に第2断裁機14に大判シート100を送り込んで断裁を行う。図6では丸数字2~5の断裁を行い、4つの列単位ブロック107に分割した様子を示している。
各列単位ブロック107は、基準辺104から等距離な平行線で断裁されるため、左右方向において高精度に等幅な短冊状とすることができる。
列単位ブロック搬送手段が、列単位ブロックを所定の間隔を保ちながら右辺方向に搬送する。
列単位ブロック107は第2断裁機14の出口側に設けられたグリッパー141により取り出され、列単位ブロック搬送レール143上を所定の間隔で往復運動する列単位ブロック搬送プッシャー142によって次工程に搬送される。
列単位ブロック搬送プッシャー142は、列単位ブロックの断裁が完了しており、左右方向の精度は断裁前よりも要求されないため、必ずしも左辺を押し搬送する構成に限定されない。またプッシャーを用いる場合にも、上記従プッシャー133のように下方回動して押し搬送する構成でもよい。
さらに、列単位ブロック搬送プッシャーは上記第1プッシャー130の一部又は全部と機構を共通にしてもよい。
上記の列単位分割工程S6では図6の丸数字5のように最後の断裁を行った後で左辺の余り部分108が生じる。そこで左辺排除手段が、最終断裁後の余り部分108を排除する工程を有してもよい。
左辺の余り部分108も大判シート100の全幅の長さの細長い紙束であるので、上記右辺排除手段と共通として、断裁刃140の直後方でこれを取り除けばよい。余り部分108を下に落とす際だけ上向き又は下向きに開放し、通常は水平に閉じた状態のバタフライ機構を設け、第1プッシャー130の押し搬送に合わせて開閉制御する。
列単位ブロック107が列単位ブロック搬送プッシャー142によって搬送された後、第2プッシャー150が、列単位ブロック107の上辺101aを下辺方向に向かって押し搬送する。第2プッシャー150は搬送方向を90度変じて、列単位ブロック107の基準辺である上辺101aを押す。基準辺を押すことによってシートのズレが生じにくくなる効果については上述した通りである。
第2プッシャー150の構造については第1プッシャー130と同様であり、第4断裁機16に到るまで同一のプッシャーで、あるいは中途位置で引き継ぎながら搬送する。
次に、第4断裁機16が、第2プッシュ工程S9の後で列単位ブロック107の下辺103aを断裁する。図7は下辺断裁工程S10及び小ブロック分割工程S12の説明図である。
下辺103aは下辺103の一部であるため上述した通り端部が不揃いであるが、図7の丸数字6の線で余り部分109を断裁する。第4断裁機16は断裁刃が上下運動しながら第2プッシャー150で前進する列単位ブロック107を断裁する。
下辺排除手段が、下辺断裁後の余り部分109を排除する。右辺排除手段と同様に、第4断裁機16の断裁刃の直後方でこれを取り除く構造を有する。余り部分109を下に落とす際だけ上向き又は下向きに開放し、通常は水平に閉じた状態のバタフライ機構を設け、第2プッシャー150の押し搬送に合わせて開閉制御する。
第4断裁機16が、第2プッシャー150の押し搬送と相互動作しながら列単位ブロック107の下端を順次断裁して小ブロック110に分割する。図7では丸数字7~13の断裁を行い、7つの小ブロック110に分割した様子を示している。
各小ブロック110は、基準辺101aから等距離な平行線で断裁されるため、上下方向において高精度に等幅な最終製品とすることができる。
上記の小ブロック分割工程S12では図7の丸数字13のように最後の断裁を行った後で上辺の余り部分111が生じる。そこで上辺排除手段が、最終断裁後の余り部分111を排除する工程を有してもよい。
上辺の余り部分111も上記下辺排除手段と共通として、断裁刃の直後方でこれを取り除けばよい。余り部分111を下に落とす際だけ上向き又は下向きに開放し、通常は水平に閉じた状態のバタフライ機構を設け、第2プッシャー150の押し搬送に合わせて開閉制御する。
(j)小ブロック搬送工程S14
搬出機17において分割された小ブロックを所定の間隔を保ちながら下辺方向に搬送して断裁装置10から搬出する。図示は省略するが、小ブロック110を第4断裁機16の出口側に設けられたグリッパーにより取り出し、所定の間隔で往復運動する小ブロック搬送プッシャーによって次工程に搬送する。
搬出された小ブロック110は図示しない帯掛け機によりブロック毎に帯掛けを行う。帯掛け機は公知の機械を適宜選択することができる。
従来、列単位ブロック107において小ブロックの中央位置に先に帯掛けを行う例があったが、撓みが生じやすく断裁精度を低下させる問題があった。本発明では小ブロックへの分割後に帯掛けを行うことで、全ての断裁工程において誤差の生じにくい断裁方法を実現している。
図8は、本発明の第2実施例に係る断裁装置20の全体説明図である。
断裁装置20において、工程順に大判シート100の突き揃え機21、計数機22、第1断裁機23、第1搬送機24、第2断裁機25、第3断裁機26、第2搬送機27、第4断裁機28、搬出機29を有する。
搬出機29から搬出された小ブロックはさらに、帯掛け装置30、整列装置31において処理される。
本実施例ではまず突き揃え機21において基本的な基準辺を決定する。このとき大判シートブロック100の紙の目に応じて、紙の目が右辺及び左辺と平行な方向になるようにシートの向きを定める。
図9は第2実施例に係る断裁方法のフローチャートである。
第1断裁機23において、大判シートブロック100の左辺104を断裁する。図10は第1断裁工程S20の説明図である。まずグリッパー230、231で上辺及び右辺を掴みながら断裁刃232により左辺104を断裁する。
左辺104は断裁により非常に高い精度で各シートが揃っているので、この断裁面を基準辺として用いる。
断裁された左辺の余り部分はそのまま落下させることで排除できる。
第1搬送機24において、断裁された大判シートブロックの左辺104を右辺方向に向かって押し搬送する。第1搬送機24には例えば4つの第1プッシャー130が備えられており、左辺104を押し搬送する。
第2断裁機25が、第1プッシュ工程S3の後で大判シートブロック100の右辺102を断裁する。図11は右辺断裁工程S4の説明図である。右辺102は上述した通り端部が不揃いであるが、第2断裁機25の断裁刃250で右辺102の余り部分を断裁する。
(D)右辺排除工程S5
右辺排除手段が、右辺断裁後の余り部分を排除する。
(E)列単位分割工程S6
第2断裁機25が、第1プッシャー130の押し搬送と相互動作しながら大判シートブロック100の右端を順次断裁して上下方向に長尺な列単位ブロック107に分割する。
(F)列単位ブロック搬送工程S8
列単位ブロック搬送手段が、列単位ブロックを所定の間隔を保ちながら右辺方向に搬送する。
第3断裁機26において、列単位ブロック107の各上辺101aを断裁する。列単位ブロック搬送手段の例えば上記列単位ブロック搬送プッシャー142と同様のプッシャーで搬送しながら、第3断裁機26の断裁刃260で上辺101aを順次断裁し、高い精度で揃った基準辺を作出する。
断裁された上辺の余り部分はそのまま落下させることで排除できる。
列単位ブロック107が例えば列単位ブロック搬送プッシャー142によって搬送された後、第2プッシャー150が、列単位ブロック107の上辺101aを下辺方向に向かって押し搬送する。第2プッシャー150は搬送方向を90度変じて、列単位ブロック107の基準辺である上辺101aを押す。第3断裁工程S21で作出された基準辺を押すことによってシートのズレは最小限に抑制される。
次に、第4断裁機28が、第2プッシュ工程S9の後で列単位ブロック107の下辺103aを断裁する。図12は下辺断裁工程S10及び小ブロック分割工程S12の説明図である。
下辺103aは下辺103の一部であるため上述した通り端部が不揃いであるが、余り部分を断裁する。第4断裁機28は断裁刃280が上下運動しながら第2プッシャー150で前進する列単位ブロック107を断裁する。
下辺排除手段が、下辺断裁後の余り部分を排除する。
(K)小ブロック分割工程S12
第4断裁機28が、第2プッシャー150の押し搬送と相互動作しながら列単位ブロック107の下端を順次断裁して小ブロック110に分割する。各小ブロック110は、基準辺101aから等距離な平行線で断裁されるため、上下方向において高精度に等幅な最終製品とすることができる。
(L)小ブロック搬送工程S14
搬出機29において分割された小ブロックを所定の間隔を保ちながら下辺方向に搬送して断裁装置20から搬出する。図示は省略するが、小ブロック110を第4断裁機28の出口側に設けられたグリッパーにより取り出し、所定の間隔で往復運動する小ブロック搬送プッシャーによって次工程に搬送する。
搬出された小ブロック110は帯掛け装置30によりブロック毎に帯掛けを行う。帯掛け機は公知の機械を適宜選択することができる。
図13は紙の目とプッシュ方向の関係を示す説明図である。紙は周知のように製紙工程における抄紙機のパルプの流れ方向に起因する紙の目(紙の流れ目)がある。プッシャーによって押し搬送をする場合、紙の目112と平行な向き(Y方向)では曲げに強く、誤差がでにくい特徴がある。一方、紙の目112と直交する向き(X方向)では曲げに弱く誤差が出やすい。
このために、右辺及び左辺に平行な方向を紙の目と一致させること、及び第1プッシュ工程で左辺を右辺方向(逆方向でも同様)に押し搬送することが重要である。
従って、これらを適切に組み合わせることによって本発明では高精度な断裁処理を実現している。
図示からも明らかな通り、シノギ(232b)側で断裁すると、断裁面がわずかに傾斜するため、本発明では基準辺を正確な端面とするように上記の通りに断裁刃を設置している。
