Description

【0001】
【産業上の利用分野】
この発明は、孔版印刷装置に関する。
【0002】
【従来の技術】
従来孔版印刷装置として、製版、印刷、排版を自動的に行う全自動タイプのものが使用され、この種の孔版印刷装置は、図7に示すようなものであり、これを参照して説明することとする。この孔版印刷装置は、原稿の画像を読み取って画像信号を出力する画像読取手段1と、前記画像信号を入力して原紙2に穿孔製版して給版する製版手段3と、製版手段3によって給版された孔版マスタ4が外周面に装着される版胴6と、使用済みの孔版マスタ4を排版する排版手段7とを有している。なお8は給紙手段、9は押圧部材、11は排紙手段をそれぞれ示し、各手段における各部材は周知に属するものであるから、その詳細についての説明は省略する。
【0003】
このような孔版印刷装置によっては、印刷を行うに際しては、作業者が画像読取手段1に原稿をセットして、図示しない製版スタートキーをオンすると、版胴6が回転してその前に行われた印刷に用いられて、版胴6に装着されたままとなっている使用済みの孔版マスタ4を、排版手段7の一対の剥離ローラ12によって版胴6の表面から剥離し、搬送部材14によって排版ボックス16に排出し、版胴6はつぎの孔版マスタ4の給版位置まで回転して停止し、マスタクランパ17を開いた状態にして次の給版動作が開始されるまで待機する。そしてセットされたつぎの原稿について製版手段3で製版して、えられた孔版マスタ4を給版して、マスタクランパ17を閉じて版胴6に装着していた。このようにして作業者が製版スタートキーをオンした後、1枚目の印刷物が排紙されるまでのファーストプリントタイムと呼ばれる時間には、製版時間にこれとは別に排版時間が加えられて、ファーストプリントタイムが長くなるという問題があった。
【0004】
そこでこのような問題を解消して、ファーストプリントタイムを短くしようということで、印刷終了後に予め排版動作を行って、このような状態でつぎの製版スタートキーをオンするまで、版胴6を前記と同様にして給版位置に待機させることが考えられる。ところでこれは、前記の問題を解消することができるが、その反面版胴6に装着した孔版マスタ4による印刷が終了したか否かは、作業者自身の判断によって決定しなければならなくて、作業者に余計な負担をかけるという問題があり、また多くの原稿について連続して印刷を行う場合には有効とはいえず、さらに版胴6から孔版マスタ4を剥離したままで長時間放置すると、孔版マスタ4を装着したままのときに比べて、インキ成分の蒸発が極端に増加して、つぎの印刷の際の立上りが悪化するという問題がある。
【0005】
【発明が解決しようとする課題】
このような問題を解消するために、特開昭61-261088号公報、特開昭61-287781号公報に開示されているようなものが提案されている。そしてこれらのものは、画像読取手段と、製版手段と、版胴と、排版手段とに加えて、製版手段と版胴との間に配置された孔版マスタを一時貯留する貯留手段とを有している。しかしながらこれらは、孔版マスタが給版されるのは、使用済み孔版マスタの排版動作が完全に終了してからであり、特に貯留手段内に他の原稿が貯留されている場合には、排版動作に要する時間が無駄になることもあって、ファーストプリントタイムの短縮を効率よく実現することができないという問題があり、また給版動作、排版動作等が画像読取手段で原稿を読み取っている際に行われるようになっているために、製版手段、版胴、排版手段の作動のためのモータ、ソレノイド、マスタクランパ等の各部材が作動していることによって振動が発生し、この振動が画像読取手段に伝達されて、読取作業に関与している各部材にぶれを生じ、いわゆるジターと呼ばれる不規則なむらが異常画像として現れるという問題がある。
【0006】
そこでこの発明の目的は、前記のような従来の孔版印刷装置のもつ問題を解消し、給版動作と排版動作とを並行して行ってファーストプリントタイムを短縮することができ、それによって給版手段と排版手段における各部材の機械的作動時間を低減して、各部材の機械的作動にともなって発生し、画像読取手段の読取作業に関与している各部材に伝達される振動を少なくすることができて、ジター等の異常画像の発生を抑制することができる孔版印刷装置を提供するにある。
【0007】
【課題を解決するための手段】
この発明は前記のような目的を達成するために、請求項1に記載の発明は、原稿の画像を読み取って画像信号を出力する画像読取手段と、前記画像信号を入力して原紙に穿孔製版して給版する製版手段と、製版手段によって給版された孔版マスタが外周面に装着される版胴と、使用済みの孔版マスタを排版する排版手段とを有する孔版印刷装置において、前記版胴から排版手段に使用済みの孔版マスタを変移する変移手段を設け、この変移手段は、排版の際に前記版胴から半径方向に離間した位置から版胴に接近した位置に移動されて孔版マスタを剥離し、この剥離後に回転する版胴が回転方向所定位置に移動されると該版胴の回転方向とは反対方向に移動して排版手段へ孔版マスタを排版することを特徴とするものである。請求項に記載の発明は、請求項1に記載の発明において、製版手段による給版動作と、排版手段による排版動作とが並行して行われることを特徴とするものである。
【0008】
【作用】
前記のような請求項1,3の発明において、印刷を行うに際しては、前記従来のものと同様に、作業者が製版スタートキーをオンすると、使用済みの孔版マスタが装着されて初期位置にある版胴が回転し、該孔版マスタの先端が排版位置に到達すると、排版手段によって孔版マスタが版胴の表面から剥離され、この排版作動が途中まで進行したところで、版胴が給版位置に向けて回転するのにタイミングを合わせて製版手段が作動を開始し、製版された孔版マスタの先端を版胴に給版して装着する。このようにして排版作動と給版作動とが並行して行われてこれらが終了すると、従来と同様にして印刷工程が行われる。
【0009】
前記のような請求項2,3の発明において、印刷を行うに際しては、前記従来のものと同様に、作業者が製版スタートキーをオンすると、使用済みの孔版マスタが装着されて初期位置にある版胴が回転しはじめ、それとほぼ同時に変移手段によって孔版マスタが版胴の表面から剥離され、その後版胴が回転を続けることによって、給版開始位置まで移動すると同時に、変移手段が版胴の回転方向とは反対方向に版胴の円周方向に沿って移動して孔版マスタを版胴の表面から剥離し、変移手段が排版位置に到達して停止すると、孔版マスタを排版手段によって排版し、この排版作動が途中まで進行したところで、版胴が給版位置に向けて回転するのにタイミングを合わせて製版手段が作動を開始し、製版された孔版マスタの先端を版胴に給版して装着する。このようにして排版作動と給版作動とが並行して行われてこれらが終了すると、従来と同様にして印刷工程が行われる。
【0010】
【実施例】
図1,2に示すこの発明の第1実施例において、前記従来のものと同様の部分は同一の符号を引用してその説明を省略し、主として異なる部分について説明する。
【0011】
この実施例は、排版手段7を矢印に示す版胴6の回転方向において製版手段3の直前に設けたものである。このようなものにおいて、印刷を行うに際しては、前記従来のものと同様に、作業者が製版スタートキーをオンすると、使用済みの孔版マスタ4が装着されて図1に示す初期位置にある版胴6のマスタクランパ17が開いて版胴6が回転し、該孔版マスタ4の先端が排版位置に到達すると、排版手段7の剥離ローラ12,13によって孔版マスタ4が版胴6の表面から剥離され、搬送部材14によって排版ボックス16に排出される。この排版作動が途中まで進行したところで、版胴6のマスタクランパ17が図2に示す位置となる給版位置に向けて、版胴6が回転するのにタイミングを合わせて製版手段3が作動を開始し、製版された孔版マスタ4の先端をマスタクランパ17に給版して、マスタクランパ17を閉じて孔版マスタ4を版胴6に装着する。このようにして排版作動と給版作動とが並行して行われてこれらが終了すると、従来と同様にして印刷工程が行われる。
【0012】
図3〜6に示すこの発明の第2実施例において、前記従来のものと同様の部分は同一の符号を引用してその説明を省略し、主として異なる部分について説明する。
【0013】
この実施例は、版胴6から排版手段7に孔版マスタ4を変移する変移手段18を設け、この変移手段18は1対の副剥離ローラ19を有していて、版胴6の円周方向に沿って移動可能となっているものである。
【0014】
このようなものにおいて、使用済みの孔版マスタ4が装着されている版胴6が図3に示す初期位置にある場合には、変移手段18は版胴6から半径方向に離間した位置に待機している。そして印刷を行うに際しては、前記従来のものと同様に、作業者が製版スタートキーをオンすると、版胴6のマスタクランパ17が開き、ついで変移手段18が半径方向に移動して、図4に示す版胴6に接近した位置に変位する。そして版胴6が回転を開始しはじめ、それとほぼ同時に変移手段18の副剥離ローラ19によって孔版マスタ4が版胴6の表面から剥離され、剥離長が所定の長さとなると副剥離ローラ19が停止する。
【0015】
その後版胴6が回転を続けることによって、図5に示すようにマスタクランパ17が給版開始位置まで移動すると同時に、変移手段18が版胴6の回転方向とは反対方向に版胴6の円周方向に沿って移動し、この間孔版マスタ4を版胴6の表面から剥離する。そして変移手段18が図6に示す排版位置に到達して停止すると、副剥離ローラ19が回転を再開して、孔版マスタ4を排版手段7の剥離ローラ12,13に向けて送りだし、孔版マスタ4は剥離ローラ12,13によって排版ボックス16に排出される。この剥離ローラ12,13による排版作動が行われている間にマスタクランパ17が給版開始位置に到達して、排版作動と並行して給版作動が行われながら、版胴6が回転を続けて給版作動と排版作動とが終了する。その後変移手段18は図3に示す初期位置に復帰し、次回の排版作動が行われるまで待機し、このようなことが繰り返えされて一連の印刷工程が行われる。
【0016】
【発明の効果】
この発明は前記のようであって、請求項1に記載の発明は、原稿の画像を読み取って画像信号を出力する画像読取手段と、前記画像信号を入力して原紙に穿孔製版して給版する製版手段と、製版手段によって給版された孔版マスタが外周面に装着される版胴と、使用済みの孔版マスタを排版する排版手段とを有する孔版印刷装置において、版胴から排版手段に使用済みの孔版マスタを変移する変移手段を設け、この変移手段は、排版の際に前記版胴から半径方向に離間した位置から版胴に接近した位置に移動されて孔版マスタを剥離し、この剥離後に回転する版胴が回転方向所定位置に移動されると該版胴の回転方向とは反対方向に移動して排版手段へ孔版マスタを排版するものであり、請求項に記載の発明は、請求項1に記載の発明において、製版手段による給版動作と、排版手段による排版動作とが並行して行われるので、ファーストプリントタイムを短縮することができ、それによって給版手段と排版手段における各部材の機械的作動時間を低減して、各部材の機械的作動にともなって発生し、画像読取手段の読取作業に関与している各部材に伝達される振動を少なくすることができて、ジター等の異常画像の発生を抑制することができるという効果がある。

[Industrial application fields]
The present invention relates to a stencil printing apparatus.
[0002]
[Prior art]
As a conventional stencil printing apparatus, a fully automatic type which automatically performs plate making, printing, and stencil printing is used. This type of stencil printing apparatus is as shown in FIG. 7, and will be described with reference to this. I will do it. The stencil printing apparatus includes an image reading unit 1 that reads an image of a document and outputs an image signal, a plate making unit 3 that inputs the image signal, perforates and feeds the base paper 2, and supplies the plate. A plate cylinder 6 on which the printed stencil master 4 is mounted on the outer peripheral surface and a plate discharging means 7 for discharging the used stencil master 4 are provided. Reference numeral 8 denotes a paper feeding means, 9 denotes a pressing member, and 11 denotes a paper discharging means. Since each member in each means is well known, a detailed description thereof will be omitted.
[0003]
In such a stencil printing apparatus, when printing is performed, when an operator sets a document on the image reading unit 1 and turns on a plate making start key (not shown), the plate cylinder 6 rotates and is performed before that. The used stencil master 4 used for printing and still attached to the plate cylinder 6 is peeled from the surface of the plate cylinder 6 by the pair of peeling rollers 12 of the plate discharging means 7 and is conveyed by the conveying member 14. The plate cylinder 6 rotates to the next plate feeding position of the stencil master 4 and stops, and the master clamper 17 is opened and waits until the next plate feeding operation is started. Then, the next set original is made by the plate making means 3 and the obtained stencil master 4 is fed, and the master clamper 17 is closed and mounted on the plate cylinder 6. In this way, after the operator turns on the plate making start key, a time called the first print time until the first printed matter is discharged, a plate discharging time is added to the plate making time. There was a problem that the first print time was prolonged.
[0004]
Therefore, by solving such a problem and shortening the first print time, the plate cylinder 6 is moved until the next plate making start key is turned on in such a state by performing a plate discharging operation in advance after the end of printing. It is conceivable to wait at the plate feeding position in the same manner as described above. By the way, this can solve the above-mentioned problem, but on the other hand, whether or not the printing by the stencil master 4 attached to the stencil cylinder 6 is finished must be determined by the operator's own judgment, There is a problem of placing an extra burden on the operator, and it is not effective when continuously printing a large number of originals. Further, if the stencil master 4 is peeled off from the plate cylinder 6 and left for a long time. As compared with the case where the stencil master 4 is left mounted, there is a problem that the evaporation of the ink component is extremely increased and the rise in the next printing is deteriorated.
[0005]
[Problems to be solved by the invention]
In order to solve such problems, those disclosed in JP-A-61-261088 and JP-A-61-287781 have been proposed. In addition to the image reading means, the plate making means, the plate cylinder, and the plate discharging means, these have storage means for temporarily storing a stencil master disposed between the plate making means and the plate cylinder. ing. However, in these cases, the stencil master is supplied after the used stencil master has been completely discharged, especially when other documents are stored in the storage means. Time may be wasted, and there is a problem that it is not possible to efficiently reduce the first print time. In addition, when the original is read by the image reading means during the plate feeding operation, the plate discharging operation, etc. Therefore, vibration is generated by the operation of the plate making means, plate cylinder, motor for operating the plate discharging means, solenoid, master clamper, and the like. There is a problem that irregularities called so-called jitter appear as an abnormal image due to shaking of each member involved in the reading work transmitted to the means.
[0006]
Accordingly, an object of the present invention is to solve the problems of the conventional stencil printing apparatus as described above, and to reduce the first print time by performing the plate feeding operation and the plate discharging operation in parallel. The mechanical operation time of each member in the means and the plate discharging means is reduced, and vibration transmitted to each member involved in the reading operation of the image reading means is reduced due to the mechanical operation of each member. An object of the present invention is to provide a stencil printing apparatus that can suppress the occurrence of abnormal images such as jitter.
[0007]
[Means for Solving the Problems]

The plate-making means starts to operate at the same time as it rotates, and the leading end of the plate-making stencil master is fed to the plate cylinder and mounted. In this way, when the plate removal operation and the plate supply operation are performed in parallel and are finished, the printing process is performed in the same manner as in the prior art.
[0009]
In the inventions of claims 2 and 3 as described above, when printing is performed, when the operator turns on the plate making start key, the used stencil master is mounted and is in the initial position as in the conventional case. The plate cylinder starts to rotate, and at the same time, the stencil master is peeled off from the surface of the plate cylinder by the shifting means, and then the plate cylinder continues to rotate, moving to the plate feeding start position, and at the same time, the shifting means rotates the plate cylinder. The stencil master is peeled off from the surface of the plate cylinder by moving in the direction opposite to the direction of the plate cylinder, and when the transition means reaches the evacuation position and stops, the stencil master is discharged by the evacuation means, When this plate removal operation has progressed partway, the plate making means starts operating at the same time as the plate cylinder rotates toward the plate feeding position, and the leading edge of the stencil master that has been made is fed to the plate cylinder. It mounted. In this way, when the plate removal operation and the plate supply operation are performed in parallel and are finished, the printing process is performed in the same manner as in the prior art.
