Description

本発明は、選択に応じて表刷り又は両面刷りに使用することができ、両面刷り法ではシリンダ上でグリッパにより導かれる、裏返しする枚葉紙がターニングドラムの紙受渡し系統により把持されて転送される後端反転方式により枚葉紙を裏返すことができる印刷機での紙送りのための装置及び方法に関する。   The present invention can be used for surface printing or double-sided printing depending on the selection. In the double-sided printing method, a sheet to be turned over, guided by a gripper on a cylinder, is gripped and transferred by a paper delivery system of a turning drum. The present invention relates to an apparatus and a method for paper feeding in a printing press capable of turning a sheet upside down by a rear end inversion method.

この種の印刷機では両面刷りの作業方式での裏返し操作は、周知のようにターニングドラムに前置したシリンダの表面から枚葉紙の前端を引き剥がすことで開始される。シリンダのリフタは裏返しする枚葉紙の前端をガイドブレードの歯の上へ持ち上げ、続いてガイドブレードが枚葉紙をシリンダから剥ぎ取り、空気圧手段に助けられてシリンダの輪郭に沿って転送し、やがて枚葉紙の後部区域で運動の逆転が行われる。この種の装置はドイツ特許公開公報ＤＥ−ＯＳ４１４０７６２で公知である。この装置の欠点は、裏返しされる枚葉紙の案内が効果的に支援されるが、裏返しされて退出する枚葉紙をいかにして案内するかの処置が示されないことである。   In this type of printing machine, the reversing operation in the double-sided printing method is started by peeling off the front edge of the sheet from the surface of the cylinder placed in front of the turning drum, as is well known. The lifter of the cylinder lifts the leading edge of the flipped sheet onto the teeth of the guide blade, and then the guide blade strips the sheet from the cylinder and transfers it along the contour of the cylinder, aided by pneumatic means, Eventually a reversal of movement takes place in the rear section of the sheet. A device of this kind is known from DE-OS 4140762. The disadvantage of this device is that it effectively assists in guiding the turned-up sheet, but does not indicate how to guide the turned-out sheet.

両面刷りで枚葉紙の裏返しの後に後端になる枚葉紙前端の案内及び送りのための装置が刊行物、ドイツ特許公開公報ＤＥ−ＯＳ４４２４９７０Ａにより公知である。この場合吸引装置で枚葉紙を時折ガイドブレードに吸引することにより、裏返しされて退出する枚葉紙が、到来する後続の枚葉紙の枚葉紙通路の外に出される。こうしてこの枚葉紙はターニングドラムの吸い口系統と吸引装置の間で強制案内によって緊張され、後続の枚葉紙の通路から出される。この紙送り装置の欠点は、退出する枚葉紙がガイドブレードの吸引装置によって短時間しか案内されないことである。遅くとも後続の枚葉紙の前端が吸引装置の前に到達した時に吸引装置の吸気が停止され、枚葉紙が解放されなければならない。ごく短時間の強制案内では、特に大きなサイズ範囲の枚葉紙やインキ管理が面倒な場合に枚葉紙の出会いを確実に回避するのに十分でない。接触の結果、印刷済みの下向きの面の裏移りが起こることがある。
退出する枚葉紙を方向の逆転の後に熊手によってガイドブレードの送り面からガイドプレートの作用区域に押しやることによって、後続の枚葉紙と退出する枚葉紙を機械的手段により互いに分離する紙送り装置がドイツ特許公開公報ＤＥ−ＯＳ４４２４９７１Ａにより公知である。退出する枚葉紙の、今や枚葉紙後端になった前端が熊手によって短時間のあいだ送られる。熊手の最先端が後続の枚葉紙の進入の前に枚葉紙の送り面の後方の出発位置をとらねばならないという条件によって、熊手の長さは限られている。この場合も退出する枚葉紙の案内は、裏返した枚葉紙と後続の枚葉紙の接触を確実に回避するのに十分でない。
ドイツ国特許出願公開公報ＤＥ４１４０７６２号明細書 ドイツ国特許出願公開公報ＤＥ４４２４９７０号明細書 ドイツ国特許出願公開公報ＤＥ４４２４９７１号明細書 An apparatus for guiding and feeding the front edge of a sheet which becomes the rear edge after turning over the sheet in double-sided printing is known from the publication DE-OS 44 24 970 A. In this case, when the sheet is occasionally sucked by the suction blade by the suction device, the sheet that is turned over and exits is taken out of the sheet path of the subsequent succeeding sheet. In this way, this sheet is tensioned by forced guidance between the mouthpiece system of the turning drum and the suction device and is taken out from the passage of the subsequent sheet. The disadvantage of this paper feeder is that the exiting sheet is only guided for a short time by the suction device of the guide blade. At the latest, when the leading edge of the succeeding sheet reaches the front of the suction device, the suction of the suction device is stopped and the sheet must be released. A very brief forced guide is not enough to reliably avoid encounters between sheets, especially when large size sheets or ink management is cumbersome. As a result of contact, the printed downside may be set off.
Paper feed that separates the subsequent sheet and the exiting sheet from each other by mechanical means by pushing the exiting sheet after the reversal of the direction by the rake from the feed surface of the guide blade to the working area of the guide plate. A device is known from DE-OS 4424971A. The leading edge of the exiting sheet, now the trailing edge of the sheet, is sent for a short time by the rake. The length of the rake is limited by the condition that the leading edge of the rake must take the starting position behind the sheet feeding surface before the subsequent sheet entry. Again, the guidance of the exiting sheet is not sufficient to reliably avoid contact between the inverted sheet and the subsequent sheet.

先行技術の欠点から出発して本発明の課題は、運動の逆転の後に枚葉紙が確実に送られる、印刷機の紙送りのための装置及び方法を提供することである。   Starting from the disadvantages of the prior art, it is an object of the present invention to provide an apparatus and method for paper feeding in a printing press in which the sheet is reliably fed after a reversal of motion.

本発明に基づきこの課題は請求項１に記載の装置及び請求項１８に記載の方法によって解決される。本発明の有利な実施態様が従属請求項で明らかである。   According to the invention, this problem is solved by an apparatus according to claim 1 and a method according to claim 18. Advantageous embodiments of the invention are apparent from the dependent claims.

本発明は、本発明に基づく紙送り装置によって枚葉紙が運動の逆転の後に確実に、たるみを生じることなく案内されるという利点がある。到来する枚葉紙と退出する枚葉紙並びに退出する枚葉紙と枚葉紙ガイドプレートの裏移りの危険がこうして取り除かれる。枚葉紙は緊張してターニングドラムへ送られる。   The invention has the advantage that the sheet feeding device according to the invention ensures that the sheet is guided after the reversal of movement without causing sagging. The danger of setback of the incoming and outgoing sheets and the outgoing sheets and sheet guide plates is thus eliminated. The sheet is tense and sent to the turning drum.

図示された実施例に基づいて本発明を詳しく説明する。   The present invention will be described in detail based on the illustrated embodiment.

図１は両面印刷機のターニングドラム１による裏返し操作の概略図を示す。周知のようにターニングドラム１には相対して相関的に相互作用する吸い口及びグリッパ系統２、３が設けられている。ターニングドラム１にシリンダ４が前置されている。一方、シリンダ４は紙送り胴５に後置されている。   FIG. 1 shows a schematic view of the turning operation by the turning drum 1 of the duplex printing machine. As is well known, the turning drum 1 is provided with mouthpieces and gripper systems 2 and 3 which interact in a relative and relative manner. A cylinder 4 is placed in front of the turning drum 1. On the other hand, the cylinder 4 is placed behind the paper feed cylinder 5.

ターニングドラム１及びシリンダ４の回転方向が記入されている。シリンダ４は圧胴、渡し胴又は受渡し胴であることができる。シリンダ４の下側にガイドブレード６が配置されている。ガイドブレード６はシリンダ４の幅にわたって伸びている。退出する裏返した枚葉紙１０の方向に伸びる紙送り装置７がガイドブレード６に設けられている。紙送り装置７はグリッパ装置、本例では動的伸縮吸い口８からなる。動的伸縮吸い口８は巡回軌道上で枚葉紙運動に適応した速度で移動させられる。締め付けグリッパを使用することも考えられる。紙送り装置７はガイドブレード６に沿って移動し得るように配置されている。こうして種々の紙型長さに適応させることが可能である。ターニングドラム１の下まで伸びるガイドプレート１１の形の枚葉紙案内装置が紙送り装置７の下に設けられている。   The rotating directions of the turning drum 1 and the cylinder 4 are entered. The cylinder 4 can be an impression cylinder, a transfer cylinder or a transfer cylinder. A guide blade 6 is disposed below the cylinder 4. The guide blade 6 extends over the width of the cylinder 4. The guide blade 6 is provided with a paper feeding device 7 that extends in the direction of the reversed sheet 10 to be withdrawn. The paper feeding device 7 comprises a gripper device, in this example, a dynamic expansion / contraction mouthpiece 8. The dynamic expansion / contraction mouthpiece 8 is moved at a speed adapted to the sheet motion on the circular trajectory. It is also conceivable to use a clamping gripper. The paper feeding device 7 is arranged so as to move along the guide blade 6. In this way, it is possible to adapt to various paper mold lengths. A sheet guide device in the form of a guide plate 11 extending under the turning drum 1 is provided under the paper feeding device 7.

図２及び３に紙送り装置７のグリッパ操作の２つの変型を示す。図１によれば動的伸縮吸い口８はリンク機構２２の連接棒２１に配置されており、リンク機構２２の支点は、押し棒１７により駆動されるスライダ２３に回転運動可能に固定されている。スライダ２３は案内路１８上で縦に移動することができる。クランク２４は曲りレバーとして形成され、その第３の支点はローラ２５を担持し、ローラ２５はローラ軌道１９上で転動する。ローラ軌道１９は機架に回転可能に支承された曲りローラフォロア２６の延長をなす。曲りローラフォロア２６のローラ２７はカム板２０の上で転動する。図３による本発明の実施態様では、垂直運動のための駆動は死点停止装置によって実現される。死点停止装置は運動逆転点で後部切換えストップ１６．１及び前部切換えストップ１６．２によって切換えられ、こうして動的伸縮吸い口８を退出面１３と休止面の間で切換える。   2 and 3 show two variations of the gripper operation of the paper feeder 7. According to FIG. 1, the dynamic expansion / contraction mouthpiece 8 is arranged on the connecting rod 21 of the link mechanism 22, and the fulcrum of the link mechanism 22 is fixed to the slider 23 driven by the push rod 17 so as to be able to rotate. . The slider 23 can move vertically on the guide path 18. The crank 24 is formed as a bending lever, and its third fulcrum carries a roller 25, and the roller 25 rolls on the roller track 19. The roller track 19 is an extension of a curved roller follower 26 that is rotatably supported by the machine. The roller 27 of the bending roller follower 26 rolls on the cam plate 20. In the embodiment of the invention according to FIG. 3, the drive for vertical movement is realized by a dead center stop device. The dead center stop device is switched by the rear switching stop 16.1 and the front switching stop 16.2 at the movement reversal point, thus switching the dynamic telescopic mouthpiece 8 between the exit surface 13 and the rest surface.

本発明に基づく装置の機能について説明する。周知のように、両面刷りの作業方式で裏返しされる枚葉紙９は圧胴４で印刷される。次に、裏返しされる枚葉紙９は圧胴４とターニングドラム１の接点を通り、裏返しされる枚葉紙９の後部区域が吸い口系統３により吸引され、ターニングドラム１の外周の下に導かれ、グリッパ系統２に引き渡され、後続の、図示しない圧胴に送られる。圧胴４の上で搬送されるときに、裏返しされる枚葉紙９は圧胴４のグリッパによって保持される。ガイドブレード６に到達する直前にグリッパが開き、裏返しされる枚葉紙９の前端が周知のように圧胴４から引き離され、ガイドブレード６に沿って導かれる。吸い口系統３が把持し、振り回した後に枚葉紙の運動の逆転が行われる。この瞬間に枚葉紙は裏返しされたとみなされる。到来する、裏返しされる枚葉紙９の前端が今や退出する裏返した枚葉紙１０の後端になる。そこで到来する、裏返しする枚葉紙９と退出する裏返した枚葉紙１０が出会うことを回避しなければならない。これは、裏返した枚葉紙１０の後端の印刷してない側を方向逆転の時点で又はその直後に紙送り装置７の動的伸縮吸い口８が把持し、通路を経て枚葉紙退出方向に導くことによって防止される。動的伸縮吸い口８は枚葉紙退出速度より低い速度で移動するから、裏返した枚葉紙１０を緊張する利点がある。動的伸縮吸い口８がその軌道上で方向逆転点に到達すると、吸気の供給が中断され、裏返した枚葉紙１０が解放される。裏返した枚葉紙１０はこの時点まで前端と後端が同時に把持されて導かれる。   The function of the device according to the present invention will be described. As is well known, the sheet 9 turned upside down by the double-sided printing method is printed by the impression cylinder 4. Next, the sheet 9 to be turned over passes through the contact point between the impression cylinder 4 and the turning drum 1, and the rear section of the sheet 9 to be turned upside down is sucked by the suction mouth system 3, and below the outer periphery of the turning drum 1. It is guided to the gripper system 2 and sent to a subsequent impression cylinder (not shown). When being conveyed on the impression cylinder 4, the sheet 9 turned upside down is held by the gripper of the impression cylinder 4. The gripper opens immediately before reaching the guide blade 6, and the front end of the sheet 9 to be turned over is pulled away from the impression cylinder 4 as is well known and guided along the guide blade 6. After the mouthpiece system 3 grips and swings, the movement of the sheet is reversed. At this moment the sheet is considered flipped. The leading edge of the incoming sheet 9 that is turned over is now the trailing edge of the reversed turned sheet 10 that is now exiting. Therefore, it is necessary to avoid encountering the sheet 9 that is turned over and the sheet 10 that is turned over and exits. This is because the dynamic expansion / contraction suction port 8 of the paper feeding device 7 grips the non-printed side of the rear end of the turned sheet 10 at the time of reversing the direction or immediately thereafter, and the sheet exits through the passage. Prevented by guiding in the direction. Since the dynamic expansion / contraction mouthpiece 8 moves at a speed lower than the sheet exit speed, there is an advantage of tensioning the inverted sheet 10. When the dynamic expansion / contraction mouthpiece 8 reaches the direction reversal point on the trajectory, the supply of the intake air is interrupted and the sheet 10 turned upside down is released. The sheet 10 turned upside down is guided by holding the front end and the rear end simultaneously until this time.

図２及び図３に示したグリッパ操作の機能は次のとおりである。動的伸縮吸い口８の水平運動は図示しない駆動装置により押し棒１７を介してスライダ２３に伝達される。垂直運動は図２に示すようにカム板２０によって導入され、ローラ２７を経て、曲りローラフォロア２６に固定したローラ軌道１９に、そこからやはりローラ２５を経て、動的伸縮吸い口８を担持するリンク機構２２に伝達することができる。動的伸縮吸い口８の受渡し位置は、ちょうど裏返し操作中の裏返しされる／裏返した枚葉紙９、１０の運動逆転点にある。そこでガイドブレード６の案内面の上に押しやられた、裏返しされる枚葉紙の前端が運動逆転点に到達すると、この紙端は運動の逆転によって、今裏返した枚葉紙１０の新たな後端になり、そのまま動的伸縮吸い口８によって吸引される。動的伸縮吸い口１２の運動は、裏返した枚葉紙１０の裏返し操作により加速された後端と同様に行われる。発明の有利な実施態様では、裏返した枚葉紙１０は動的伸縮吸い口８の僅かな差動により常に緊張している。裏返しされる枚葉紙９の、送り面１２に送られる前端をよけて、裏返しされる枚葉紙９との一切の接触をなくすために、緊張した裏返し枚葉紙１０は動的伸縮吸い口８により水平案内に加えて垂直方向にも、送り面１２の下にある退出面１３に移される。同じく無接触でガイドプレート１１を通過し、裏返した枚葉紙１０をターニングドラム１に円滑に送ることができるように、裏返した枚葉紙１０が後端強制案内で通過する行程は裏返し区域にまで至ることが好ましい。このプロセス技術的に最適な変型では、交互に働く動的伸縮吸い口８を使用し、裏返し区域で裏返した枚葉紙１０をちょうど今解放した第１の動的伸縮吸い口が退出面１３の下の休止面に戻され −動的伸縮吸い口が休止中１５− 、裏返しされる枚葉紙９の受渡しが第２の動的伸縮吸い口８によってちょうどその時行われるようにすることが必要である。   The functions of the gripper operation shown in FIGS. 2 and 3 are as follows. The horizontal movement of the dynamic expansion / contraction mouthpiece 8 is transmitted to the slider 23 via the push rod 17 by a driving device (not shown). The vertical movement is introduced by the cam plate 20 as shown in FIG. 2, and the dynamic expansion / contraction suction port 8 is carried from the roller track 19 fixed to the bending roller follower 26 via the roller 27 to the roller track 25 from there. It can be transmitted to the link mechanism 22. The delivery position of the dynamic expansion / contraction mouthpiece 8 is located at the motion reversal point of the sheets 9 and 10 that are reversed / inverted during the reversing operation. Therefore, when the front end of the sheet to be turned over pushed onto the guide surface of the guide blade 6 reaches the movement reversal point, the sheet end is moved to a new rear side of the sheet 10 turned upside down by the reversal of the movement. It becomes an end and is sucked by the dynamic expansion / contraction mouthpiece 8 as it is. The movement of the dynamic expansion / contraction mouthpiece 12 is performed in the same manner as the rear end accelerated by the flipping operation of the reversed sheet 10. In an advantageous embodiment of the invention, the inverted sheet 10 is always tensioned by a slight differential of the dynamic telescopic mouthpiece 8. In order to avoid any contact with the sheet 9 that is turned inside out by avoiding the front edge of the sheet 9 that is turned inside out and fed to the feeding surface 12, the tensioned turned sheet 10 is dynamically stretched. In addition to horizontal guidance, the mouth 8 moves in the vertical direction to the exit surface 13 below the feed surface 12. Similarly, the process of passing the turned-up sheet 10 by the rear end forced guide passes to the inside-out area so that the turned-up sheet 10 can be smoothly fed to the turning drum 1 without passing through the guide plate 11. Is preferable. In this process-technical variant, the first dynamic telescopic mouthpiece, which used the alternating dynamic telescopic mouthpiece 8 and just released the sheet 10 turned upside down in the inside-out area, is the exit surface 13. It is necessary to make sure that the sheet 9 to be turned over is returned by the second dynamic telescopic mouthpiece 8 at that time, when it is returned to the lower rest surface-the dynamic telescopic mouthpiece is at rest 15- is there.
