Description

本発明は、用紙の表面と裏面に印刷や各種加工を行う印刷機において、給紙部のロール紙より用紙を繰り出して、印刷部や巻取部、折部などの後処理装置部までの各種処理工程に従って用紙を紙通しする紙通し装置に関するものである。   The present invention is a printing machine that performs printing and various processing on the front and back surfaces of paper, and feeds the paper from the roll paper of the paper feed unit to various post-processing device units such as a printing unit, a winding unit, and a folding unit. The present invention relates to a paper threading device for threading paper according to a processing step.

上記した印刷機やこれの下流側に配置される加工機における案内ローラ間に処理順に従って手を差し入れて用紙を通していく作業は、場所によっては狭い作業空間で行わなければならないところもあって困難であると共に、時間を要し、また上記用紙の走行経路には乾燥機やスリッタがあって高温部分や刃物部分があって上記手作業では危険であった。   The operation of inserting the hand between the guide rollers in the above-described printing machine and the processing machine arranged downstream thereof according to the processing order and passing the paper is difficult because there is a place that needs to be performed in a narrow work space depending on the place. In addition, it takes time, and there are dryers and slitters in the travel path of the paper, and there are high-temperature parts and blade parts.

これらのことから、用紙の走行経路の一側端部に、この用紙の走行経路に沿って機械的に走行する平ベルトあるいはワイヤ等の紐体を設け、この紐体に用紙の先端を連結し、紐体を走行駆動することにより用紙を用紙の走行経路に機械的に紙通しするようにした紙通し装置がある（例えば、特許文献１参照）。   For these reasons, a string member such as a flat belt or a wire that mechanically travels along the sheet traveling path is provided at one end of the sheet traveling path, and the leading end of the sheet is connected to the string member. In addition, there is a paper threading device that mechanically feeds a paper along a paper travel path by driving the string (see, for example, Patent Document 1).

そして上記用紙の走行経路には、用紙の表と裏を反転する用紙反転装置を備えたものがあり、この用紙反転装置にも、これの走行方向側方部に上記機械式の紙通し経路が設けられている。   The paper travel path includes a paper reversing device that reverses the front and back of the paper, and the paper reversing device also has the mechanical paper threading path on the side in the travel direction. Is provided.

図１に用紙反転装置部ａにおける従来の紙通し経路を示す。この用紙反転装置ａは進入する用紙に対して反転して出ていく用紙が側方へオフセットするタイプのもので、第１と第２のターンバーｂ，ｃを直角に交差し、１本の張り出しローラｄを、この用紙反転装置ａに進入する用紙ｅの走行方向と平行に配置した構成になっていて、進入してきた用紙ｅを第１のターンバーｂから張り出しローラｄ、第２のターンバーｃを経て走行させることにより、この用紙ｅが反転されると共に、進入経路に対して用紙の幅方向にオフセットされた状態で出ていくようになっている。   FIG. 1 shows a conventional paper threading path in the paper reversing device section a. This sheet reversing device a is of a type in which the sheet that is reversed with respect to the entering sheet is offset to the side, and intersects the first and second turn bars b and c at a right angle to form a single overhang. The roller d is arranged in parallel with the traveling direction of the paper e entering the paper reversing device a, and the paper e that has entered the projecting roller d and the second turn bar c are projected from the first turn bar b. By traveling through the sheet e, the sheet e is reversed and exits in a state offset with respect to the entry path in the sheet width direction.

そしてこの用紙反転装置ａにおける従来の紙通し装置は、各ターンバーｂ，ｃ及び張り出しローラｄのそれぞれと同径の案内プーリｆ１，ｆ２，ｆ３，ｆ４，ｆ５からなる案内プーリ群を用紙反転装置ａの周囲に設け、これらの案内プーリ群を巻回走行する平ベルトｇにて用紙ｅが牽引されて紙通しされるようになっている。 A conventional paper threading device in the paper reversing device a is a guide pulley group including guide pulleys f 1 , f 2 , f 3 , f 4 , and f 5 having the same diameter as each of the turn bars b and c and the extending roller d. Is provided around the sheet reversing device a, and the sheet e is pulled by a flat belt g that winds around these guide pulley groups to pass the sheet.

実公昭４５−３３９００号公報Japanese Utility Model Publication No. 45-33900

上記した従来の紙通し装置で、特に用紙反転装置部における紙通し装置は上記したように、用紙牽引用の紐体を案内する案内ローラ群の各案内ローラが、ターンバー及び張り出しローラとは別体で、しかも第１、第２のターンバーｂ，ｃの周囲に用紙を案内する案内プーリｆ１，ｆ２，ｆ４，ｆ５はターンバーｂ，ｃの軸心の向きとは無関係に配置されていたため、この用紙反転装置ａまわりの紙通しがスムーズに行われず、この部分で用紙ｅに折筋が発生し、その折筋が原因で用紙切れなどが生じて用紙の牽引ができなくなる場合があり、作業者の手作業にて正常な紙通し経路に復帰させなければならないという問題があった。 In the above-described conventional paper threading device, particularly the paper threading device in the paper reversing device section, as described above, each guide roller of the guide roller group for guiding the paper pulling string is separate from the turn bar and the overhanging roller. In addition, the guide pulleys f 1 , f 2 , f 4 , and f 5 for guiding the paper around the first and second turn bars b and c are arranged regardless of the direction of the axis of the turn bars b and c. Therefore, there is a case where the paper reversing device a is not smoothly threaded, a crease is generated in the paper e at this portion, and the folds may cause the paper to run out, thereby making it impossible to pull the paper. There has been a problem that the operator has to return to a normal paper threading path manually.

本発明は上記した従来の紙通し装置の問題を解決して用紙反転装置部における紙通しを折筋がつくことなくスムーズに行うことができるようにした紙通し装置を提供しようとするもので、その構成は、ターンバーを用いた用紙反転装置を途中に有する用紙の走行経路の幅方向の側端部に、用紙の走行経路に沿って紙通し駆動装置にて走行するようにしてワイヤを設け、このワイヤに用紙の先端部を連結して紙通しするようにした紙通し装置において、上記用紙反転装置のターンバーの端部に、このターンバーに摺動通過する用紙の摺動軌跡と平行の螺旋状の溝を設け、この溝にて上記ワイヤを案内するようにした構成になっている。   The present invention is intended to provide a paper threading device that solves the above-described problems of the conventional paper threading device and can smoothly perform the paper threading in the paper reversing device unit without a crease, The configuration is such that a wire is provided at the side end in the width direction of the paper travel path having a paper reversing device using a turn bar so as to travel along the paper travel path by the paper threading drive device, In the paper threading device in which the leading end portion of the paper is connected to the wire to pass the paper, the end of the turn bar of the paper reversing device has a spiral shape parallel to the sliding locus of the paper slidingly passing through the turn bar. This groove is provided, and the wire is guided by this groove.

そしてこの紙通し装置において、ワイヤを走行駆動するワイヤ駆動装置が、原動機にて回転駆動される駆動プーリと、この駆動プーリの上流側と下流側とに位置する第１・第２のガイドプーリと、この両ガイドプーリの間に位置するループ用プーリとからなり、両ガイドプーリの間で、ワイヤをループ用プーリを介して駆動プーリに複数回巻き付けるようにすると共に、ワイヤに用紙の先端部に連結する連結部を、ワイヤの略１ｍごとに設けた。   In this paper threading device, a wire driving device that travels and drives the wire includes a driving pulley that is rotationally driven by a prime mover, and first and second guide pulleys that are positioned upstream and downstream of the driving pulley. The loop pulley is located between the two guide pulleys, and the wire is wound around the drive pulley through the loop pulley between the two guide pulleys, and the wire is attached to the leading end of the paper. The connection part to connect was provided about every 1 m of the wire.

本発明によれば、ターンバーを用いた用紙反転装置を途中に有する用紙の走行経路への紙通しを、用紙反転装置において用紙に折筋が発生することなくスムーズに行うことができる。   According to the present invention, it is possible to smoothly pass a sheet having a sheet reversing device using a turn bar to a traveling path of a sheet in the middle without causing a folding line in the sheet reversing device.

また、本発明に係る紙通し装置では、紙通し用のワイヤを走行駆動するためのワイヤ駆動装置において、ワイヤが駆動プーリに複数回巻き掛けられるワイヤは、１回ごとにループ用プーリに巻き掛けることにより、このワイヤ駆動装置におけるワイヤの走行駆動がからまることなく良好に行うことができる。   In the paper threading device according to the present invention, in the wire driving device for driving and driving the paper threading wire, the wire wound around the drive pulley is wound around the loop pulley every time. As a result, it is possible to satisfactorily carry out the traveling driving of the wire in this wire driving device.

さらに本発明によれば、紙通しするためのワイヤに、このワイヤと用紙の先端を連結する連結部が略１ｍごとと、近い間隔に設けられていることにより、ワイヤの略どの位置からでも用紙を牽引走行を開始でき作業性をよくすることができる。   Furthermore, according to the present invention, the connecting portion for connecting the wire and the leading end of the paper is provided at a distance of approximately 1 m and a distance close to the wire for passing the paper. It is possible to start towing and improve workability.

本発明の実施の形態を図２以下に基づいて説明する。   An embodiment of the present invention will be described with reference to FIG.

図２はインクジェット印刷装置１における紙通し装置２を示すもので、この紙通し装置２は、インクジェット印刷装置１の用紙Ｗの走行経路に沿ってループ状に設けてある。   FIG. 2 shows a paper threading device 2 in the ink jet printing apparatus 1, and this paper threading device 2 is provided in a loop shape along the travel path of the paper W of the ink jet printing apparatus 1.

インクジェット印刷装置１はその一例として、給紙部３と、複数のインクジェットヘッド４ａ，４ｂ，４ｃ，４ｄを有するインクジェット記録ユニット４と、乾燥機５と、巻取り装置６とからなっており、これの用紙Ｗの走行経路は給紙部３の上方に位置する最上流側のガイドローラ７ａからインクジェット記録ユニット４、乾燥機５を通り、最下流側のガイドローラ７ｂにわたって多数のガイドローラにて構成されている。   As an example, the ink jet printing apparatus 1 includes a paper feeding unit 3, an ink jet recording unit 4 having a plurality of ink jet heads 4a, 4b, 4c, and 4d, a dryer 5, and a winding device 6. The travel path of the paper W is composed of a large number of guide rollers from the uppermost guide roller 7 a located above the paper feed unit 3 to the inkjet recording unit 4 and the dryer 5 and across the most downstream guide roller 7 b. Has been.

このインクジェット印刷装置１のインクジェット記録ユニット４は、幅方向にずれた位置で用紙Ｗの表裏の両面に印刷できるようになっていて、まず幅方向の一方側で表側を印刷し、その後用紙反転装置８で反転すると共に幅方向に平行移動され、これの幅方向他方側で裏側に印刷するようになっている。用紙反転装置８は表面印刷行程の乾燥機５の下流側と、インクジェット記録ユニット４の裏側印刷行程の入口側との間に設けられている。   The ink jet recording unit 4 of the ink jet printing apparatus 1 can print on both the front and back sides of the paper W at positions shifted in the width direction. First, the front side is printed on one side in the width direction, and then the paper reversing device. Inverted at 8 and translated in the width direction, and printed on the back side on the other side in the width direction. The sheet reversing device 8 is provided between the downstream side of the dryer 5 in the front side printing process and the inlet side in the back side printing process of the inkjet recording unit 4.

そして紙通し装置２は、上記したように、最上流側のガイドローラ７ａから最下流側のガイドローラ７ｂにて構成される上記用紙Ｗの走行経路を往路とし、この往路では後述する用紙反転装置８のターンバーを除く各ガイドローラと乾燥機５の乾燥ドラム９の軸端部に設けられたガイドプーリにワイヤ１０が巻き掛けられ、復路では上記最下流側のガイドローラ７ｂから最上流側のガイドローラ７ａにわたって適宜のガイドプーリに案内されている。   As described above, the paper threading device 2 uses the traveling path of the paper W constituted by the guide roller 7b on the most downstream side from the guide roller 7a on the most upstream side as a forward path. The wire 10 is wound around each guide roller excluding the turn bar 8 and a guide pulley provided at the shaft end portion of the drying drum 9 of the dryer 5, and in the return path, the guide on the most upstream side from the guide roller 7 b on the most downstream side. The roller 7a is guided by an appropriate guide pulley.

紙通し装置２のワイヤ１０には、これの略１ｍ間隔に図３に示すようにロック金具１１によりワイヤ輪１２が設けてあり、このうちの１つのワイヤ輪１２に、フック１３、リードワイヤ１４、クリップ１５を介して用紙Ｗの幅方向片側の先端が連結されており、ワイヤ１０が紙通し駆動装置１６にて走行することにより用紙Ｗがワイヤ１０にて牽引されるようになっている。   As shown in FIG. 3, the wire 10 of the paper threading device 2 is provided with a wire ring 12 by a lock fitting 11 at an interval of about 1 m, and a hook 13 and a lead wire 14 are provided on one of the wire rings 12. The leading end of one side in the width direction of the paper W is connected via the clip 15, and the paper 10 is pulled by the wire 10 as the wire 10 travels by the paper threading drive device 16.

上記したように、用紙Ｗはこれの幅方向の片側で牽引されるが、用紙反転装置８にて反転されると、この牽引部が用紙Ｗの幅方向反対側へ変わる。   As described above, the paper W is pulled on one side in the width direction of the paper W, but when the paper W is reversed by the paper reversing device 8, the pulling portion is changed to the opposite side of the paper W in the width direction.

すなわち、最上流側のガイドローラ７ａから用紙反転装置８までの用紙Ｗの牽引が、例えば原動機側（ＧＳ）で行われ、用紙反転装置８からワイヤ駆動装置１６までは操作側（ＯＳ）で行われる。そしてワイヤ駆動装置１６の下流側に設けた牽引位置変更装置１７にて再びＧＳ側に戻るようになっている。図２において、ワイヤ１０がＧＳ側を通る部分を実線で、ＯＳ側を通る部分を点線で示した。   That is, the pulling of the paper W from the uppermost guide roller 7a to the paper reversing device 8 is performed, for example, on the prime mover side (GS), and from the paper reversing device 8 to the wire driving device 16 is performed on the operating side (OS). Is called. The traction position changing device 17 provided on the downstream side of the wire driving device 16 returns to the GS side again. In FIG. 2, a portion where the wire 10 passes the GS side is indicated by a solid line, and a portion where the wire 10 passes the OS side is indicated by a dotted line.

このように、用紙反転装置８の上流側と下流側ではワイヤ８の牽引位置が変わるので、用紙反転装置８の上流側と下流側の用紙Ｗが紙通しされるインクジェット記録ユニット１と乾燥機５では、インクジェット記録ユニット１の各ガイドローラの軸方向両側と乾燥機５の乾燥ドラム９の軸方向両側に、それぞれと同径のワイヤ用のガイドプーリが設けられている。図７にてインクジェット記録ユニット部のガイドローラの両側にガイドプーリを設ける例を示した。   In this way, the pulling position of the wire 8 changes between the upstream side and the downstream side of the paper reversing device 8, and therefore the inkjet recording unit 1 and the dryer 5 through which the paper W on the upstream side and downstream side of the paper reversing device 8 is passed. Then, wire guide pulleys having the same diameter are provided on both sides in the axial direction of each guide roller of the inkjet recording unit 1 and on both sides in the axial direction of the drying drum 9 of the dryer 5. FIG. 7 shows an example in which guide pulleys are provided on both sides of the guide roller of the ink jet recording unit.

ワイヤ駆動装置１６は図４、図５に示すようになっていて、ＯＳ側のフレーム１８ａに支持され、モータ１９にて駆動される減速機２０の出力軸２１に固定した駆動プーリ２２と、この駆動プーリ２２の上流側と下流側に位置する第１、第２のガイドプーリ２３ａ，２３ｂと、この両ガイドプーリ２３ａ，２３ｂの間に位置するループ用プーリ２３ｃとからなり、両ガイドプーリ２３ａ，２３ｂの間で、ワイヤ１０はループ用プーリ２３ｃを介して駆動プーリ２２に２周にわたって巻き掛けられている。駆動プーリ２２の周面にはワイヤの滑り止めのために樹脂性弾性体が被覆してある。   4 and 5, the wire driving device 16 is supported by the OS side frame 18 a and is fixed to the output shaft 21 of the speed reducer 20 driven by the motor 19. The first and second guide pulleys 23a and 23b located on the upstream side and the downstream side of the drive pulley 22 and the loop pulley 23c located between the two guide pulleys 23a and 23b. Between the wires 23b, the wire 10 is wound around the drive pulley 22 through the loop pulley 23c over two turns. The peripheral surface of the drive pulley 22 is covered with a resinous elastic body to prevent the wire from slipping.

この構成において、駆動プーリ２２に巻き掛けられるワイヤ１０の１周目と２周目の間でループ用プーリ２３ｃにてループが構成されるので、ワイヤ１０を複数回巻き掛けた駆動プーリ２２によるワイヤ１０の走行駆動がワイヤ１０がワイヤ駆動装置１６において、からまることなく良好に行われる。なお、ループ用プーリ２３ｃの案内溝を２条、３条にすることにより、このループ用プーリ２３ｃを介して駆動プーリ２２へのワイヤ１０の巻き付けを３回転、４回転とすることができる。   In this configuration, since a loop is formed by the loop pulley 23c between the first and second turns of the wire 10 wound around the drive pulley 22, the wire by the drive pulley 22 wound around the wire 10 a plurality of times. The travel drive 10 is performed satisfactorily without the wire 10 being tangled in the wire drive device 16. In addition, by setting the guide groove of the loop pulley 23c to two and three, the winding of the wire 10 around the drive pulley 22 through the loop pulley 23c can be made three rotations and four rotations.

また、牽引位置変更装置１７は図５に示すようになっていて、ワイヤ駆動装置１６の下流側にＯＳ側のフレーム１８ａに支持された第１のガイドプーリ２４ａと、ＧＳ側のフレーム１８ｂに支持された第２のガイドプーリ２４ｂとからなり、この両ガイドプーリ２４ａ，２４ｂによりワイヤ１０がＯＳ側からＧＳ側に戻されるようになっている。   The traction position changing device 17 is configured as shown in FIG. 5, and is supported by a first guide pulley 24a supported by the OS side frame 18a on the downstream side of the wire driving device 16 and a GS side frame 18b. The second guide pulley 24b is configured so that the wire 10 is returned from the OS side to the GS side by the two guide pulleys 24a and 24b.

上記ワイヤ１０の復路の適当な位置に、図６に示すようにＳ字状にワイヤ１０を巻き掛ける２個のガイドプーリ２５ａ，２５ｂの一方をばね２６にて他方から離れる方向に付勢することによりワイヤ１０にテンションを与えるテンション付与装置２７が設けてある。   As shown in FIG. 6, one of the two guide pulleys 25a and 25b for winding the wire 10 in an S-shape is urged to an appropriate position on the return path of the wire 10 by a spring 26 in a direction away from the other. Thus, a tension applying device 27 for applying tension to the wire 10 is provided.

図７は図２に示したインクジェット印刷装置１に用いる用紙反転装置８を示すもので、この用紙反転装置８は上記したように表面印刷工程の乾燥機５の下流側と、裏面印刷行程の入口部間に配置されていて、表面印刷経路（イ）から裏面印刷経路（ロ）にわたって用紙Ｗを反転しながら幅方向に移動する幅方移動型のものである。   FIG. 7 shows the paper reversing device 8 used in the ink jet printing apparatus 1 shown in FIG. 2, and this paper reversing device 8 is the downstream side of the dryer 5 in the front surface printing process and the entrance of the back surface printing process as described above. It is arranged between the sections, and is of a width-moving type that moves in the width direction while reversing the paper W from the front surface printing path (A) to the back surface printing path (B).

そしてこれの構成は、表面印刷経路（イ）からの用紙Ｗを９０度方向を変える第１のターンバー２８と、この用紙Ｗを１８０度反転させる張り出しローラ２９と、この張り出しローラ２９からの用紙を裏面印刷経路（ロ）に向けて９０度方向を変えると共に幅方向に移動する第２のターンバー３０とからなっている。第１と第２のターンバー２８，３０は直交状態で固定されており、また張り出しローラ２９は図示しないモータにて用紙Ｗの走行速度と等速で回転するようになっている。   And, this configuration consists of a first turn bar 28 that changes the direction of the paper W from the front surface printing path (A) by 90 degrees, an extension roller 29 that reverses the paper W by 180 degrees, and a sheet from the extension roller 29.
