Description
本発明は印刷用原版を製作する製版機に関し、特に製版機の給紙装置に関する。 The present invention relates to a plate making machine for producing a printing original plate, and more particularly to a paper feeding device of the plate making machine.
周知のように、製版機のマスター用紙としては、湿度や温度による影響を受けない樹脂ベースマスターが主流ではあるが、樹脂ベースマスターは高価であるため、最近では、図１に示すようなアルミ箔を裏打ちした安価なペーパベース・マスターが提案されている。 As is well known, a resin base master that is not affected by humidity and temperature is the mainstream as a master sheet of the plate making machine, but since the resin base master is expensive, recently, an aluminum foil as shown in FIG. An inexpensive paper-based master lined with the above has been proposed.
つまり、図１のペーパベース・マスターは、ペーパ基材ｍ２の表面に感光層ｍ３を形成し、同感光層ｍ３とは反対側の裏面に導電性アルミ箔ｍ１を裏打ちした構造であり、ロール状に巻かれた状態で供給される。
ところで、安価な同ペーパベース・マスターは、アルミ箔ｍ１の存在のため、塑性変形を起こし易く、ロール状に巻かれた状態のマスターを単に給紙ローラ等の給紙手段で引き出して用いると、巻かれた状態のカール（巻き癖）や給紙中に形成されるループの塑性変形が一部に残り、感光層ｍ３の表面を均一に帯電することが困難になる問題が発生する。
本発明の目的は、以上に述べたような従来のペーパベース・マスター用紙の問題に鑑み、ロール状に巻かれた状態のマスター用紙であっても、巻き癖を矯正して供給できる製版機の給紙装置を得るにある。
By the way, the inexpensive paper base master is prone to plastic deformation due to the presence of the aluminum foil m1, and when the roll-shaped master is simply pulled out by a paper feed means such as a paper feed roller, The curl in a wound state and the plastic deformation of the loop formed during sheet feeding remain in part, and there arises a problem that it becomes difficult to uniformly charge the surface of the photosensitive layer m3.
In view of the problems of the conventional paper base master paper as described above, the object of the present invention is to provide a plate making machine that can correct and supply curl even if it is a master paper wound in a roll shape. Get a paper feeder.
この目的を達成するため、本発明は、繰出ローラで引き出されるマスター紙をカッターで切断した後、給紙ローラの回転送りにより帯電部入口ローラに引き渡す製版機の給紙装置において、前記マスター紙を感光層の反対側表面に導電性アルミ箔を有するペーパ基材で構成し、前記マスター紙を送る前記給紙ローラの回転周速度を前記帯電部入口ローラの対応周速度よりも大きくして給紙ローラと帯電部入口ローラの間にマスター紙のループを形成し、同ループの先端を前記帯電部入口ローラの位置に誘導する給紙部出口上ローラを設け、同給紙部出口上ローラに対して作動器により離間距離を変えてマスター紙の巻き癖などの塑性変形を矯正する給紙部出口下ローラを給紙部出口上ローラの下方に配置した製版機の給紙装置を提案するものである。 In order to achieve this object, the present invention provides a paper feeding device of a plate making machine that cuts a master paper drawn by a feeding roller with a cutter and then delivers the master paper to a charging unit entrance roller by rotational feeding of the paper feeding roller. Constructed with a paper base material having conductive aluminum foil on the opposite surface of the photosensitive layer, and feeding the master paper with the rotational peripheral speed of the paper feed roller larger than the corresponding peripheral speed of the charging unit entrance roller A master paper loop is formed between the roller and the charging unit entrance roller, and a paper feed unit exit upper roller is provided to guide the tip of the loop to the position of the charging unit entrance roller. A paper feeding device for a plate making machine in which a lower roller at a paper feeding unit outlet that corrects plastic deformation such as curl of master paper by changing the separation distance by an actuator is disposed below the upper roller at the paper feeding unit outlet. A.
本発明によれば、給紙ローラと帯電部入口ローラとの間に意識的にマスター紙のループを形成し、帯電部入口ローラに供給する前に給紙ローラで巻き癖を矯正できるから、障害なく後続処理を行うことができ、安価なペーパベース・マスター用紙の利点を充分に発揮させることができる。 According to the present invention, a master paper loop is consciously formed between the paper feed roller and the charging unit entrance roller, and the curl can be corrected by the paper feed roller before being supplied to the charging unit entrance roller. The subsequent processing can be performed without any problems, and the advantages of inexpensive paper-based master paper can be fully exhibited.

以下、図２から図８について本発明の実施例の詳細を説明する。
図２は感光層ｍ３の反対側表面に導電性アルミ箔ｍ１を有するペーパ基材ｍ２で構成されるマスター紙ロールＲを用いる製版機であって、同マスター紙ロールＲから引き出されたマスター紙Ｍは、本発明による給紙装置Ａにより所定寸法にカットされ、帯電装置Ｂにおいて、その感光層ｍ３に帯電される。
The details of the embodiment of the present invention will be described below with reference to FIGS.
FIG. 2 shows a plate making machine using a master paper roll R composed of a paper base material m2 having a conductive aluminum foil m1 on the opposite surface of the photosensitive layer m3. The master paper M drawn from the master paper roll R is shown in FIG. Is cut to a predetermined size by the paper feeding device A according to the present invention, and charged by the charging device B to the photosensitive layer m3.
そして、マスター紙Ｍの帯電された感光層ｍ３の表面には、露光ローラ装置Ｃを通過する間にレーザスキャナＤからの画像が走査され、走査された静電潜像は、スプレー現像装置Ｅを通る際に顕像化される。画像の現像後、同画像は定着装置Ｆを通過する際に定着され、排紙ローラＧの働きで排紙トレーＨ上に排出されることになる。 The surface of the charged photosensitive layer m3 of the master paper M is scanned with an image from the laser scanner D while passing through the exposure roller device C, and the scanned electrostatic latent image is transferred to the spray developing device E. Visualized when passing. After the image is developed, the image is fixed when passing through the fixing device F, and is discharged onto the paper discharge tray H by the function of the paper discharge roller G.
図３は本発明による給紙装置の詳細を示し、マスター紙ロールＲに巻かれたマスター紙Ｍは繰出ローラ１の回転により繰り出され、同繰出ローラ１と給紙ローラ２との間に配置されるカッター３により所定の長さに切断され、同給紙ローラ２よりも遅い周速度で回転される帯電部入口ローラ４に引き取られ、後続の帯電装置Ｂに供給される。
また、帯電部入口ローラ４の最寄の位置には、自由に回転できるように給紙部フレーム５に軸支される給紙部出口上ローラ６が位置され、この給紙部出口上ローラ６により、マスター紙Ｍに対してループの曲率とは逆の曲率が与えられ、マスター紙Ｍの巻き癖が矯正される。
FIG. 3 shows the details of the paper feeding device according to the present invention. The master paper M wound around the master paper roll R is fed by the rotation of the feeding roller 1 and is arranged between the feeding roller 1 and the paper feeding roller 2. The sheet is cut to a predetermined length by the cutter 3 and is taken up by the charging unit entrance roller 4 rotated at a lower peripheral speed than the paper feed roller 2 and supplied to the subsequent charging device B.
Further, at the nearest position of the charging unit entrance roller 4, a sheet feeding unit outlet upper roller 6 that is pivotally supported by the sheet feeding unit frame 5 so as to freely rotate is positioned. Thus, a curvature opposite to the curvature of the loop is given to the master paper M, and the curl of the master paper M is corrected.
給紙ローラ２と前記給紙部出口上ローラ６との間の空間中には、上端部を傾動軸７で傾動可能に給紙部フレーム５に支持されたガイド部材８が配置され、前記給紙ローラ２から帯電部入口ローラ４に向かってマスター紙Ｍの先端部を案内するガイド板９がガイド部材８の上部に固定される。このガイド板９の帯電部側端部にはガイド部材８の傾動により前記給紙部出口上ローラ６に対する距離を変える給紙部出口下ローラ１０が軸支され、巻き癖を矯正する際、同給紙部出口下ローラ１０は給紙部出口上ローラ６に接近されて給紙部出口上ローラ６の周面にマスター紙Ｍの表面を圧接して巻き癖を矯正できる。
また、前記ガイド部材８の下部にはボールベアリングで構成する従動ローラ１１が設けられ、この従動ローラ１１は、マスター紙Ｍのループを検出する検出器からの信号又は給紙ローラ２の回転開始から一定時間経過後の信号で励磁されるロータリソレノイド１２に従動される。即ち、前記ロータリソレノイド１２は突出した操作部材１２ａを有し、この操作部材１２ａはロータリソレノイド１２の励磁により従動ローラ１１の運動軌跡内に介入し、傾動軸７を中心としてガイド部材８を図６図示のように傾動させる。
In the space between the paper feed roller 2 and the paper feed unit outlet upper roller 6, a guide member 8 supported by the paper feed unit frame 5 so that the upper end portion thereof can be tilted by the tilt shaft 7 is disposed. A guide plate 9 that guides the leading end portion of the master paper M from the paper roller 2 toward the charging portion entrance roller 4 is fixed to the upper portion of the guide member 8. A sheet feeding unit outlet lower roller 10 that changes the distance to the sheet feeding unit outlet upper roller 6 by the tilting of the guide member 8 is pivotally supported at the charging unit side end of the guide plate 9, and the same is applied when correcting curling. The sheet feeding unit outlet lower roller 10 can approach the sheet feeding unit outlet upper roller 6 and press the surface of the master paper M against the peripheral surface of the sheet feeding unit outlet upper roller 6 to correct curl.
Further, a driven roller 11 composed of a ball bearing is provided below the guide member 8, and this driven roller 11 is based on a signal from a detector that detects a loop of the master paper M or from the start of rotation of the paper feed roller 2. It is driven by a rotary solenoid 12 that is excited by a signal after a certain time has elapsed. That is, the rotary solenoid 12 has a protruding operation member 12a. The operation member 12a intervenes in the movement locus of the driven roller 11 by the excitation of the rotary solenoid 12, and the guide member 8 with the tilt shaft 7 as the center is shown in FIG. Tilt as shown.
図示実施例の製版機の給紙装置は、以上のような構造であるから、次のように作動する。
先ず、製版機の制御装置（図示せず）から給紙信号が入力されると、繰出ローラ１及び給紙ローラ２が回転されてマスター紙ロールＲからマスター紙Ｍが引き出され、図４図示のように、マスター紙Ｍの先端部はガイド板９に沿って案内され、帯電部入口ローラ４に突き当たった状態となる。この場合、帯電部入口ローラ４は未だ停止状態にあるため、引き続くマスター紙Ｍの供給により、図５に示すように、給紙ローラ２と帯電部入口ローラ４との間の空間にマスター紙Ｍの巻き癖によるループが形成されるけれども、このループの基部は給紙部出口上ローラ６の周面に接触された状態になる。
Since the sheet feeding device of the plate making machine of the illustrated embodiment has the above structure, it operates as follows.
First, when a paper feed signal is input from a control device (not shown) of the plate making machine, the feeding roller 1 and the paper feed roller 2 are rotated, and the master paper M is pulled out from the master paper roll R, as shown in FIG. As described above, the leading end portion of the master paper M is guided along the guide plate 9 and comes into contact with the charging portion entrance roller 4. In this case, since the charging unit entrance roller 4 is still in a stopped state, the master paper M is supplied to the space between the sheet feeding roller 2 and the charging unit entrance roller 4 as shown in FIG. However, the base portion of the loop is in contact with the peripheral surface of the sheet feeding unit outlet upper roller 6.
次に、ループの検出信号または給紙ローラ２の回転開始から一定時間後に発信される指令信号により、ロータリソレノイド１２が励磁され、同ロータリソレノイド１２の操作部材１２ａが従動ローラ１１に係合し、図６に示すように、傾動軸７を中心としてガイド部材８が傾動され、同ガイド部材８に支持された給紙部出口下ローラ１０が上昇され、この給紙部出口下ローラ１０が給紙部出口上ローラ６に接近される。
続いて、マスター紙Ｍは帯電装置へ送られるが、給紙部出口下ローラ１０の上昇によって帯電部入口ローラ４の直前のマスター紙Ｍは、給紙部出口上ローラ６の周面に確実に押圧・接触され、マスター紙Ｍに付いた巻き癖とは反対側に曲率中心をもった給紙部出口上ローラ６との接触で巻き癖などの塑性変形が矯正される。この巻き癖矯正時においては、給紙部出口下ローラ１０は給紙部出口上ローラ６に接近した状態にあるため、通過するマスター紙Ｍの一部が確実に給紙部出口上ローラ６の周面に圧接されるから、アルミ箔ｍ１の存在による巻き癖などの変形状態が解消されることになる。
Next, the rotary solenoid 12 is excited by a loop detection signal or a command signal transmitted after a predetermined time from the start of rotation of the paper feed roller 2, and the operation member 12a of the rotary solenoid 12 is engaged with the driven roller 11, As shown in FIG. 6, the guide member 8 is tilted about the tilting shaft 7, the paper feed unit outlet lower roller 10 supported by the guide member 8 is raised, and the paper feed unit outlet lower roller 10 is fed. The part exit upper roller 6 is approached.
Subsequently, the master paper M is sent to the charging device, but the master paper M immediately before the charging unit entrance roller 4 is surely placed on the peripheral surface of the feeding unit exit upper roller 6 by the ascent of the feed unit exit lower roller 10. Plastic deformation such as curl is corrected by contact with the upper roller 6 that is pressed and contacted and has a curvature center on the side opposite to the curl attached to the master paper M. At the time of curling correction, since the lower roller 10 of the paper feeding unit exit is in a state of being close to the upper roller 6 of the paper feeding unit outlet, a part of the master paper M passing through the roller of the paper feeding unit outlet upper roller 6 is surely received. Since it is pressed against the peripheral surface, the deformed state such as curl due to the presence of the aluminum foil m1 is eliminated.
なお、図７はカッター３によりマスター紙Ｍが切断された後、切断されたマスター紙Ｍの大部分が帯電装置へ送り出された状態を示し、この図７の状態後、図８のように、マスター紙Ｍの後端部が給紙装置を出るまで、給紙部出口下ローラ１０は給紙部出口上ローラ６に接近した位置をとる。 FIG. 7 shows a state in which the master paper M is cut by the cutter 3 and then most of the cut master paper M is sent to the charging device. After the state of FIG. 7, as shown in FIG. Until the trailing edge of the master sheet M exits the sheet feeding device, the sheet feeding unit outlet lower roller 10 is positioned close to the sheet feeding unit outlet upper roller 6.
なお、前述した本発明の実施例においては、作動器としてロータリソレノイド１２を用いた構造を説明したけれども、本発明においては、ガイド部材８を傾動操作するには、かならずしもロータリソレノイド１２を用いる必要はなく、例えば往復型ソレノイドや制御モータであってもよい。 In the embodiment of the present invention described above, the structure using the rotary solenoid 12 as the actuator has been described. However, in the present invention, it is not necessary to use the rotary solenoid 12 to tilt the guide member 8. For example, a reciprocating solenoid or a control motor may be used.
