Description

本考案は輪転印刷機に付設され印刷後のウェブを所定の長さごとに断裁して折 紙する折機に関するものである。 The present invention relates to a folding machine attached to a rotary printing machine, which cuts and folds a printed web into predetermined lengths.
【０００２】[0002]
ウェブ輪転印刷機には、印刷後に乾燥冷却されたウェブを所定の長さごとに断 裁したり、断裁されたウェブを幅方向または長さ方向に折紙したりする折機を備 えている。この折機による折り方には、断裁前のウェブをフォーマで幅方向に半 折するフォーマ折りや、断裁後の折丁を折紙胴で長さ方向に半折する平行１回折 り、断裁後の折丁を折紙胴で長さ方向に４つ折する平行２回折り、平行折りされ た折丁をチョッパで平行折りと直交方向へ半折するチョッパ折り等があり、これ らの折り方は、折丁の仕様にしたがい選択されて単独で用いられたり、このうち のいくつかが組合わされて用いられたりする。 The web rotary printing machine is equipped with a folding machine that cuts the dried and cooled web after printing into predetermined lengths, and folds the cut web in the width direction or the length direction. Folding by this folding machine includes former folding in which the web before cutting is folded in half in the width direction with a former, and parallel folding in which the signature after cutting is folded half in the length direction with an origami cylinder, and after cutting. There are two folds in which the signature is folded in parallel with the origami cylinder in the lengthwise direction, two folds in parallel with the chopper, and a chopper fold in which the signature is folded in half in the orthogonal direction with a chopper. They are selected according to the specifications of Ding and used alone, or some of them are used in combination.
【０００３】 これら各種の折紙装置のうちの平行１回折り装置は、互いに周面をほゞ対接さ せた断裁胴と折胴およびくわえ胴とを備えており、断裁胴の断裁刃で所定長ごと に断裁されたウェブを、折胴の差込みナイフとくわえ胴のくわえ板とで半折して チョッパ装置または排紙用の羽根車へ送り込むように構成されている。また、チ ョッパ折り装置は、上記くわえ胴から搬送ベルトで搬送されてきた折丁を紙当て に当てて停止させ、停止した折丁の中央部へ向って垂直姿勢で下降してくる板状 のチョッパブレードで折丁を中央から折りながら下方のローラ間へ押込むことに より半折するものである。Among these various origami devices, the parallel folding device includes a cutting cylinder whose peripheral surfaces are almost in contact with each other, a folding cylinder and a gripping cylinder, and a predetermined cutting edge of the cutting cylinder. It is configured that the web cut into lengths is half-folded by the insertion knife of the folding cylinder and the holding plate of the holding cylinder and fed to the chopper device or the impeller for discharging paper. In addition, the chopper folding device stops the signature conveyed by the conveyor belt from the gripper cylinder against a paper holder to stop it, and then descends in a vertical posture toward the center of the stopped signature. The chopper blade folds the signature from the center and pushes it between the rollers below to fold it in half.
【０００４】 このチョッパ折りに際しては、折丁の搬送速度が速いと、紙当てに当たったと きに折丁が跳ね返ることがあって良好な折り精度が確保できなかったり、折丁が 傷付いて印刷物の品質を低下させたりするので、ある速度以上の高速化が不可能 であり、上限速度が制約される。そこで従来、チョッパ装置を用いる場合には、 止むを得ず印刷装置および排紙装置を含めた印刷機全体の速度を下げなければな らず、これによって生産性がいちじるしく低下するという問題がある。When the chopper is folded, if the conveyance speed of the signature is high, the signature may bounce when hitting a paper pad, failing to ensure good folding accuracy, or the signature may be damaged and the printed matter may be damaged. It will not be possible to increase the speed above a certain speed, and the upper limit speed will be restricted. Therefore, conventionally, when a chopper device is used, it is unavoidable that the speed of the entire printing machine including the printing device and the paper discharging device must be reduced, which causes a problem that productivity is drastically reduced.
【０００５】 そこで従来、平行折り装置の最終胴である上記くわえ胴と、チョッパ装置への 搬送径路との間に、くわえ胴よりも周速の遅い減速胴を設けてくわえ胴のくわえ 板から減速胴の爪にくわえ替えられたのち排出される折丁の排出速度を遅くする とともに、この減速胴以降の折丁搬送径路を２系列設けてくわえ胴から減速胴へ くわえ替えられる折丁を、減速胴とこれに対接する上下の各渡し胴との間のくわ え替えを経て前記２系列の各折丁搬送径路へ交互に送り込み、各折丁搬送径路内 にそれぞれ設けたチョッパ装置で折丁を折って排出することにより良好な生産性 を確保することが行われている。Therefore, conventionally, a deceleration cylinder having a slower peripheral speed than the gripper cylinder is provided between the gripper cylinder, which is the final cylinder of the parallel folding device, and the conveying path to the chopper device to reduce the speed from the gripper plate of the gripper cylinder. The discharge speed of signatures that are discharged after being gripped by the tongue of the body is slowed down, and two signature transfer paths after this deceleration cylinder are provided to reduce the speed of the signature that can be gripped from the gripping cylinder to the deceleration cylinder. Through the gripping between the cylinder and the upper and lower transfer cylinders that are in contact with the cylinder, they are alternately fed into each of the two series of signature transport paths, and the signatures are provided by the chopper device provided in each signature transport path. Good productivity is ensured by breaking and discharging.
【０００６】 ところがこの場合、くわえ胴と減速胴との間に周速差があるからくわえ胴のく わえ板から減速胴の爪へのくわえ替えができないので、従来、これを解決するた めにくわえ胴と減速胴との回転食い込み部周面に近接してくわえ胴の周面に対接 する紙送りころを設け、また、くわえ胴と減速胴との回転吐出部周面に近接して 機台側に支持された折丁ガイドと当てとを設けることが提案されている。However, in this case, since there is a peripheral speed difference between the gripper cylinder and the speed reduction cylinder, it is not possible to replace the gripper plate of the gripper cylinder with the claw of the speed reduction cylinder. Providing a paper feed roller that is in contact with the peripheral surface of the gripping cylinder and the speed reducing cylinder and is in contact with the peripheral surface of the gripping cylinder, and close to the peripheral surface of the rotary discharge part between the gripping cylinder and the speed reducing cylinder. It has been proposed to provide a signature guide and a pad supported on the machine base side.
【０００７】 こうすることにより、くわえ胴のくわえ板が折丁をくわえから解放したのち、 前記当てに当接して減速胴の爪が折丁をくわえるまでの間に折丁ガイドに沿って 移動する折丁が無保持になるタイミングができるので、このタイミングの間に、 前記紙送りころをくわえ胴の周面に圧接させることにより、折丁は、紙送りころ とくわえ胴の周面との間で尻側を挟持されて送られ、くわえ替えにより前記２径 路へ交互に送り込まれる。By doing so, after the gripper plate of the gripper cylinder releases the signature from the gripper, it moves along the signature guide until it touches the pad and the claw of the speed reduction cylinder grips the signature. Since there is a timing at which the signature is not held, the signature can be pressed between the paper feed roller and the peripheral surface of the gripper cylinder by pressing the paper feed roller against the peripheral surface of the gripper cylinder during this timing. Then, the buttocks are clamped and sent, and the grippers are alternately sent to the two paths.
【０００８】[0008]
しかしながら、このような従来の装置においては、くわえ胴のくわえ板から減 速胴のくわえ板への折丁のくわえ替えに際し、折丁の先端部が減速胴のくわえ板 にくわえられるまで無保持であることにより、紙質によっては前記送りころから 当てまでの間で折丁が弛むので、当てに当たらないことがあり、また、くわえ胴 のくわえ板でくわえられたときの曲がり癖が伸ばされずに残って折丁がチョッパ の当てに当たらないことがある。この結果、減速胴と渡し胴との間で行われる折 丁の受渡し時やチョッパ折り時における折丁の位置がばらついてチョッパ折り精 度が低下するという問題がある。さらに折丁ガイトを固定して設けたものにおい ては、折丁が折丁ガイドに接触しながら搬送されることにより紙詰まりや傷が発 生して損紙の発生量が増えたり、印刷物の品質が低下したりするという問題があ る。 However, in such a conventional device, when the signature of the gripper cylinder is changed from the gripper plate of the gripper cylinder to the gripper plate of the deceleration cylinder, there is no holding until the tip of the signature is gripped by the gripper plate of the deceleration cylinder. Depending on the paper quality, the signature may slacken between the feed roller and the pad, so it may not hit the pad, and the bending habit when held by the gripper of the gripper remains unstretched. The signature may not hit the chopper. As a result, there is a problem in that the position of the signatures varies when the signatures are transferred between the reduction cylinder and the transfer cylinder and when the choppers are folded, and the chopper folding accuracy decreases. Furthermore, in the case where the signature guide is fixed, when the signature is conveyed while contacting the signature guide, paper jams and scratches may occur, increasing the amount of wasted paper, There is a problem that the quality is reduced.
【０００９】 本考案は以上のような点に鑑みなされたもので、くわえ胴とその下流側相手胴 との間の折丁の受渡しを、折丁を弛ませたり傷付けたりすることなく行うことを 可能にした輪転印刷機の折機を提供することを目的としている。The present invention has been made in view of the above points, and it is possible to transfer a signature between the gripping cylinder and the downstream counterpart cylinder without loosening or damaging the signature. It is an object of the present invention to provide a folding machine for a rotary printing machine that has made it possible.
【００１０】[0010]
このような目的を達成するために本考案では、くわえ部材を有するくわえ胴と このくわえ胴よりも周速度が遅く前記くわえ部材との間で折丁をくわえ替えるく わえ部材を有しくわえ胴の折丁搬送下流側に位置してこれとほゞ対接する相手胴 とを備えた輪転印刷機の折機において、くわえ胴と相手胴との回転吐出側に位置 する案内部材を設け、この案内部材とくわえ胴の周面とに添接する折丁案内ベル トを張架した。 In order to achieve such an object, the present invention has a gripper cylinder having a gripper member and a gripper member having a gripper member having a peripheral speed lower than that of the gripper member and changing the signature between the gripper member and the gripper member. In a folding machine of a rotary printing press, which is provided on the downstream side of the signature transport and has a counter cylinder that is almost in contact with it, a guide member is provided on the rotary discharge side of the gripper cylinder and the counter cylinder, and this guide is provided. A signature guide belt was attached to the member and the peripheral surface of the gripper.

This web is cut by the rotating cutting cylinder, folding cylinder and gripper cylinder, folded once in parallel, gripped by the gripper plate of the gripper cylinder, and attached to the peripheral surface of the gripper cylinder. This signature is changed from the gripper of the gripper to the gripper of the other hand, discharged from between the cylinders, wrapped around the mating cylinder, and then transported to the chopper device via the transfer cylinder. .. When the signatures are delivered between the gripper cylinder and the counter cylinder, the signatures released from the grips are pressed against the peripheral surface of the speed reduction cylinder by the signature guide belt, so the signatures are delivered in a position where they are securely positioned. As it is carried and conveyed, the bend when it is held in the gripper plate extends and becomes straight.

【００２３】 折丁２０を保持した針１０は、折胴７とくわえ胴１２との回転により、これら 両胴７，１２の対接点を通り越し、折丁２０の長さ方向中央部が両胴７，１２の 対接点に達したときに差込みナイフ１１とくわえ板１３とが対向して差込みナイ フ１１が半径方向に前進するので、折丁２０の中央部がくわえ板１３に押込まれ て半折される。くわえ胴１２が回転すると、半折された折丁２０は、カム機構等 により折胴７の周面から胴芯方向へ退去する針１０の保持から解放されたのち引 っ張られてくわえ胴１２の上側周面に巻付けられる。このとき、紙送りころ１６ は小径部をくわえ胴１２の周面に対向させているので、折丁２０の搬送を妨げな い。The needle 10 holding the signature 20 passes by the rotation of the folding cylinder 7 and the gripping cylinder 12 and passes through the contact points of the two cylinders 7 and 12, and the central portion in the length direction of the signature 20 has both cylinders 7. , 12 when the contact point of the insert knife 11 and the gripper plate 13 face each other, the insert knife 11 moves forward in the radial direction, so the center of the signature 20 is pushed into the gripper plate 13 and half-folded. To be done. When the grip cylinder 12 rotates, the half-folded signature 20 is released from the holding of the needle 10 that is retracted from the circumferential surface of the folding cylinder 7 in the core direction by a cam mechanism or the like, and is then stretched to the grip cylinder 12. Is wrapped around the upper surface of the. At this time, since the small diameter portion of the paper feed roller 16 faces the peripheral surface of the gripper cylinder 12, the conveyance of the signature 20 is not hindered.
【００２４】 さらに両胴１２，１４が回転して図３に示すように、折丁２０をくわえ板本体 １８とくわえ台１９とでくわえるくわえ板１３が、両胴１２，１４の中心を結ぶ 線Ｌの手前に達したのち、図４に示す状態以降においては、くわえ板１３のくわ え板本体１８がくわえ台１９に対して開き、折丁２０をくわえから解放する。ま た図４において、折丁２０は折丁案内ベルト２８に接触し始め、図４に示す状態 から図５に示す状態になる過程において折丁２０の先端がくわえ胴１２の胴周切 欠き１２ａ内から押し出されるとともに、くわえ板１３にくわえられていたとき の曲がりが伸びて真っ直ぐになる。Furthermore, as shown in FIG. 3, the two drums 12, 14 further rotate, and the gripper plate 13 holding the signature 20 with the gripper plate body 18 and the gripper base 19 forms a line connecting the centers of the two cylinders 12, 14 with each other. After reaching the front of L, after the state shown in FIG. 4, the gripper plate body 18 of the gripper plate 13 is opened with respect to the gripper base 19, and the signature 20 is released from the gripper. Further, in FIG. 4, the signature 20 starts to come into contact with the signature guide belt 28, and in the process from the state shown in FIG. 4 to the state shown in FIG. As it is pushed out from the inside, the bend when being held by the holding plate 13 extends and becomes straight.
【００２５】 この状態からさらに両胴１２，１４が回転すると、減速胴１４の周速がくわえ 胴１２の周速よりも遅いことにより、くわえ板１３がくわえ板１５に追い付くと ともに、くわえ板本体１８がくわえ台１９に対して開く。また、図５に示すよう に折丁２０は折丁案内ベルト２８によって減速胴１４の周面に圧接され、これに よってくわえ板１３にくわえられていたときの折丁２０の曲がりがさらに伸ばさ れて真っ直ぐになる。このように、折丁２０は、折丁案内ベルト２８によって案 内されるが、このとき紙送りころ１６が回動してその大径部が折丁２０の後半部 を折丁案内ベルト２８のくわえ胴１２への添接部に圧接させて送るので、折丁２ ０は、くわえ板本体２２とくわえ台２３との間に突っ込まれてその先端が当て２ ４に当接し、このあとくわえ板１５のくわえ板本体２２がくわえ台２３に対して 閉じるので、折丁２０はこの閉じたくわえ面にくわえられ、減速胴１４の周面に 巻付けられて搬送される。When both cylinders 12 and 14 are further rotated from this state, the peripheral speed of the reduction cylinder 14 is lower than the peripheral speed of the gripper cylinder 12, so that the gripper plate 13 catches up with the gripper plate 15 and the gripper plate main body is caught. 18 opens to the mouthpiece 19. Further, as shown in FIG. 5, the signature 20 is pressed against the peripheral surface of the reduction cylinder 14 by the signature guide belt 28, which further extends the bend of the signature 20 when it is held by the gripper plate 13. Become straight. As described above, the signature 20 is designed by the signature guide belt 28, and at this time, the paper feed roller 16 is rotated so that the large diameter portion of the signature guide belt 28 moves the latter half of the signature 20. Since the signature 20 is pressed against the gripper 12 and sent, the signature 20 is thrust between the gripper body 22 and the gripper 23, and the tip of the signature 20 abuts the abutment 24. Since the gripper plate main body 22 of 15 is closed with respect to the gripper 23, the signature 20 is gripped by the closed gripper surface, wound around the peripheral surface of the reduction cylinder 14, and conveyed.
【００２６】 次いで図６に示すように、折丁２０をくわえたくわえ板１５が減速胴１４の回 転により折丁搬送ベルト２８から離れて行き、折丁２０は、その後半部を折丁搬 送ベルト２８により減速胴１４に圧接されて案内される。そしてこの折丁２０は くわえ爪３０が真上へきたときに開くことによりくわえから解放されて搬送ベル ト３４で搬送され、上部チョッパ装置３５の当て３６に当接することにより停止 したのち、チョッパ３７の下降によりチョッパ折りされる。Next, as shown in FIG. 6, the holding plate 15 holding the signature 20 moves away from the signature conveying belt 28 due to the rotation of the reduction cylinder 14, and the signature 20 transports the latter half of the signature. The belt 28 is pressed against and guided by the reduction cylinder 14. The signature 20 is released from the grip by opening the gripper 30 when the gripper 30 is directly above and is transported by the transport belt 34. The signature 20 is stopped by contacting the pad 36 of the upper chopper device 35, and then the chopper 37. The chopper is folded by the descending of.
【００２７】 次の折丁２０はくわえ胴１２のくわえ板１３から減速胴１４のくわえ板３３に くわえ替えられたのち、下部渡し胴３１のくわえ爪３２にくわえ替えられ、この 折丁２０は、くわえ爪３２が真上へきたときに開くことによりくわえから解放さ れて搬送ベルト３８で搬送され、下部チョッパ装置３９の当て４０に当接するこ とにより停止したのち、チョッパ４１の下降によりチョッパ折りされる。The next signature 20 is changed from the grip plate 13 of the grip cylinder 12 to the grip plate 33 of the speed reduction cylinder 14, and then to the grip claw 32 of the lower transfer cylinder 31. When the gripper claw 32 is opened right above, it is released from the gripper and conveyed by the conveyor belt 38, stopped by abutting against the pad 40 of the lower chopper device 39, and then lowered by the chopper 41 to fold the chopper. To be done.
【００２８】 このあと、折丁２０は上部のチョッパ装置３５と下部のチョッパ装置３９とへ 交互に搬送されてチョッパ折りされる。この場合、チョッパ装置３５，３９への 供給速度は減速胴１４によって減速されており、また折丁２０の供給間隔は、上 下のチョッパ装置３５，３９へ交互に供給されることにより拡がっているので、 印刷速度が高速であってもチョッパ装置３５，３９において当て３６，４０への 高速衝突により折丁２０に傷が発生したり折丁２０が詰まったりするというよう なことがない。After that, the signature 20 is alternately conveyed to the upper chopper device 35 and the lower chopper device 39 to be chopper folded. In this case, the supply speed to the chopper devices 35 and 39 is reduced by the speed reduction cylinder 14, and the supply interval of the signature 20 is expanded by being alternately supplied to the upper and lower chopper devices 35 and 39. Therefore, even if the printing speed is high, there is no possibility that the chopper devices 35 and 39 collide with the abutments 36 and 40 at a high speed and the signature 20 is scratched or clogged.
