【考案の詳細な説明】[Detailed description of the device]

【0001】[0001]

【産業上の利用分野】[Industrial applications]

本考案は、輪転印刷機の折機に関する。 The present invention relates to a folding machine of a rotary printing press.

【0002】[0002]

【従来の技術】[Prior Art]

巻紙輪転印刷機には、印刷後、乾燥冷却されたウェブを所定の長さ毎に断裁し たり、これを幅方向や長さ方向に折ったりする折機が備えられている。 The web-fed rotary printing machine is equipped with a folding machine that cuts the dried and cooled web after printing to a predetermined length and folds the web in the width direction and the length direction.

【0003】 図5はこの種の折機の一例の構成図である。図5において、11はフォーマ、 12はニッピング装置、13は平行折装置、14はチョッパ折装置である。この 折機では、ウェブWはフォーマ11で幅方向に半折され、続くニッピング装置1 2の縦筋目胴15及び横筋目胴16で後で折られる折丁の折位置に筋目を入れら れる。尚、場合によっては筋目の代わりにミシン目を入れることもあり、本明細 書においてはこれらを特に区別しないときは、総称して折目という。ウェブWは そこを通った後に平行折装置13に入り、その断裁胴17で定寸法に断裁される と共に、折胴18及びくわえ胴19にて前記横筋目胴16で付けられた筋目に沿 って断裁方向と平行に折られ折丁となる。この折丁はさらに減速胴20を介して 渡胴21に送られてチョッパ折装置14へ送られる。チョッパ折装置14で折丁 は上述の平行折りと直交する方向に前記縦筋目胴15で付けられた筋目に沿って 半折され、羽根車23を介して排紙コンベア22上へ排紙される。FIG. 5 is a block diagram of an example of this type of folder. In FIG. 5, 11 is a former, 12 is a nipping device, 13 is a parallel folding device, and 14 is a chopper folding device. In this folding machine, the web W is half-folded in the width direction by the former 11 and is scored at the folding position of the signature to be folded later by the vertical stirrup body 15 and the horizontal stirrup body 16 of the nipping device 12. In some cases, perforations may be inserted instead of the creases, and in the present specification, unless otherwise specified, they are collectively referred to as folds. After passing through it, the web W enters the parallel folding device 13, is cut into a predetermined size by the cutting cylinder 17 thereof, and is cut by the folding cylinder 18 and the gripping cylinder 19 along the creases attached by the transverse crease cylinder 16. And folded parallel to the cutting direction to form a signature. This signature is further sent to the transfer cylinder 21 via the reduction cylinder 20 and then to the chopper folding device 14. In the chopper folding device 14, the signature is half-folded in the direction orthogonal to the above-mentioned parallel folding along the creases attached by the vertical stirrup body 15, and is discharged onto the discharge conveyor 22 via the impeller 23. ..

【0004】 チョッパ折装置14には、折丁の進行方向に対して直交する方向(幅方向)に 装置を移動させるサイドレイ装置が備えられている。チョッパ折装置14を折丁 の幅方向に移動させる理由は、図6に示すように、チョッパ折装置14で折られ た折丁の端面にずれSを与えるチョッパ折ラップを設定したり、折丁の紙幅に対 して折工程の性能が適切に発揮しやすい位置へ調整するためである。The chopper folding device 14 is provided with a side lay device that moves the device in a direction (width direction) orthogonal to the traveling direction of the signature. The reason for moving the chopper folding device 14 in the width direction of the signature is to set a chopper folding wrap that gives a shift S to the end face of the signature folded by the chopper folding device 14 as shown in FIG. This is to adjust the position so that the folding process performance can be appropriately exhibited with respect to the paper width.

【0005】 また、サイドレイ装置によるチョッパ折装置14の移動に合わせて、縦筋目胴 15の筋目付け刃も移動できるようになっている。Further, the scoring blade of the vertical scoring body 15 can also be moved in accordance with the movement of the chopper folding device 14 by the side lay device.

【0006】 サイドレイ装置によってチョッパ折装置14を移動させた場合、その移動量に 合わせて縦筋目胴15の筋目付け刃を移動させ、筋目の位置とチョッパ折装置1 4の折り位置とを一致させている。When the chopper folding device 14 is moved by the side lay device, the scoring blade of the vertical streaks 15 is moved in accordance with the amount of movement to match the position of the creases with the folding position of the chopper folding device 14. ing.

【0007】[0007]

【考案が解決しようとする課題】[Problems to be solved by the device]

チョッパ折装置14の移動量と筋目付け刃の移動量を合わせて正確に両者の位 置を一致させることは、移動調節機構のねじ部のガタやダイヤルの精度が原因で 困難であった。また、サイドレイ装置と筋目付け刃の移動機構とを機械的に連結 し、両者の位置を常に同位置に維持するようにすることも考えられる。しかし、 サイドレイ装置と縦筋目胴15は離れた位置にあり、中間には折機の胴が配置さ れていることもあって、複雑な構成となり、サイドレイ装置と筋目付け刃の移動 機構とを機械的に連結することは困難であった。従って、従来はサイドレイ装置 と筋目付け刃の移動機構を個別に操作していた。このため、移動量の調節を行な っている間に折られた折丁は折精度が悪く、そのほとんどは不良となっていた。 It was difficult to accurately match the positions of the chopper folding device 14 and the scored blade by adjusting the amount of movement of the chopper folding device 14 and the precision of the dial of the movement adjusting mechanism. It is also conceivable to mechanically connect the side lay device and the movement mechanism of the scored blade so that the positions of the both are always maintained at the same position. However, since the side lay device and the vertical streak body 15 are distant from each other and the folding machine body is arranged in the middle, the structure becomes complicated, and the side lay device and the movement mechanism of the scoring blade are combined. It was difficult to connect mechanically. Therefore, in the past, the side lay device and the movement mechanism of the scoring blade were individually operated. For this reason, the folding accuracy of the signatures folded while adjusting the movement amount was poor, and most of them were defective.

【課題を解決するための手段】[Means for Solving the Problems]

上記課題を解決するための本考案の構成は、折丁の進行方向に直交する方向に 移動自在なチョッパ折装置と、チョッパ折位置に対応してウェブに折目を付ける 折目付け手段と、折目付け手段をウェブの幅方向に移動させる移動機構と、チョ ッパ折装置の移動量を検出する移動量検出装置と、移動量検出装置の情報に基づ いて移動機構を作動させチョッパ折装置の移動量に応じて折目付け手段の移動を 連動させる制御装置とを備えたことを特徴とする。 The configuration of the present invention for solving the above-mentioned problems is composed of a chopper folding device movable in a direction orthogonal to the traveling direction of a signature, a crease means for making a crease on a web corresponding to a chopper folding position, and a fold device. A moving mechanism that moves the weighting means in the width direction of the web, a movement amount detection device that detects the movement amount of the chopper folding device, and the movement mechanism is operated based on the information from the movement amount detection device to activate the chopper folding device. A control device for interlocking the movement of the crease forming means in accordance with the amount of movement is provided.

【実施例】【Example】

図1には本考案の一実施例に係る折機の動作ブロック図、図2にはその回路構 成図、図3には縦筋目胴の断面図、図4にはサイドレイ装置の概略構成図を示し てある。 FIG. 1 is an operation block diagram of a folding machine according to an embodiment of the present invention, FIG. 2 is a circuit configuration diagram thereof, FIG. Is shown.

【0011】 図3に基づいて縦筋目胴の構成を説明する。The structure of the vertical streaks will be described with reference to FIG.

【0012】 縦筋目胴51は、ニッピングローラ52と複数の紙押えローラ53がシャフト 54に備えられた押え部55とで構成されている。押え部55のシャフト54に は、エアシリンダ56で押圧駆動される筋目付け刃57が設けられている。シャ フト54の両端はフレーム58に軸方向に移動自在に支持されている。The vertical streaks 51 are composed of a nipping roller 52 and a pressing portion 55 having a plurality of paper pressing rollers 53 provided on a shaft 54. The shaft 54 of the pressing portion 55 is provided with a scored blade 57 that is pressed by an air cylinder 56. Both ends of the shaft 54 are supported by a frame 58 so as to be movable in the axial direction.

【0013】 一方側のフレーム58にはねじ軸59が回転自在に支持され、ねじ軸59は駆 動歯車60及び従動歯車61を介してモータ62によって駆動される。ねじ軸5 9にはナット63が噛み合い、ナット63はシャフト54の端部に固定されてい る。つまり、モータ62の駆動によりねじ軸59が駆動され、ナット63を介し てシャフト54が軸方向に移動する。尚、図中の符号で64は筋目付け刃57の 位置検出装置である。A screw shaft 59 is rotatably supported on the frame 58 on one side, and the screw shaft 59 is driven by a motor 62 via a drive gear 60 and a driven gear 61. A nut 63 meshes with the screw shaft 59, and the nut 63 is fixed to the end of the shaft 54. That is, the screw shaft 59 is driven by the drive of the motor 62, and the shaft 54 moves in the axial direction via the nut 63. Incidentally, reference numeral 64 in the drawing denotes a position detecting device for the scored blade 57.

【0014】 ナット63には連結フレーム65を介してスリーブ66が取付けられ、スリー ブ66はフレーム58に摺動自在に支持されている。スリーブ66にはニッピン グローラ52の端部が回転自在且つ軸方向に移動不能に支持されている。つまり 、モータ62の駆動によりナット63を介してシャフト54と共にニッピングロ ーラ52が軸方向に移動する。尚、図中67はニッピングローラ52の駆動用歯 車、68はモータ62のブレーキ、69は移動制限用検知スイッチである。A sleeve 66 is attached to the nut 63 via a connecting frame 65, and the sleeve 66 is slidably supported by the frame 58. The end of the nipping roller 52 is supported by the sleeve 66 so as to be rotatable and immovable in the axial direction. That is, the nipping roller 52 moves in the axial direction together with the shaft 54 via the nut 63 by the driving of the motor 62. In the figure, 67 is a driving toothed wheel of the nipping roller 52, 68 is a brake of the motor 62, and 69 is a movement limit detection switch.

【0015】 上記構成の移動機構により、モータ62の駆動によってシャフト54及びニッ ピングローラ52が軸方向に移動し、筋目付け刃57の位置調整を行なう。With the moving mechanism having the above structure, the shaft 54 and the nipping roller 52 are moved in the axial direction by the driving of the motor 62, and the position of the scored blade 57 is adjusted.

【0016】 図4に基づいてサイドレイ装置の構成を説明する。The configuration of the side lay device will be described with reference to FIG.

【0017】 チョッパブレード71、チョッパローラ72及び羽根車73から構成されるチ ョッパ折装置74は、レール75に移動自在に支持されている。チョッパ折装置 74のステイ76にはナット77が固定され、ナット77にはねじ軸78が噛み 合っている。ねじ軸78はフレーム79に支持され、ハンドル80によって回転 される。レール75には移動量検出装置としてのチョッパ位置検出装置81が設 けられ、チョッパ位置検出装置81によってチョッパ折装置74の移動位置が検 出される。A chopper folding device 74 including a chopper blade 71, a chopper roller 72, and an impeller 73 is movably supported by a rail 75. A nut 77 is fixed to a stay 76 of the chopper folding device 74, and a screw shaft 78 is meshed with the nut 77. The screw shaft 78 is supported by the frame 79 and is rotated by the handle 80. A chopper position detecting device 81 as a moving amount detecting device is provided on the rail 75, and the moving position of the chopper folding device 74 is detected by the chopper position detecting device 81.

【0018】 図1,図2に基づいて制御装置を説明する。The control device will be described with reference to FIGS. 1 and 2.

【0019】 チョッパ位置検出装置81の検出情報は制御装置としての位置制御増幅器82 に入力され、モータ62はチョッパ折装置74の移動量に応じた位置制御増幅器 82の指令によって正,逆回転駆動される。この時、位置検出装置64によって 筋目付け刃57の移動量が位置制御増幅器82にフィードバックされる。The detection information of the chopper position detecting device 81 is input to a position control amplifier 82 as a control device, and the motor 62 is driven to rotate normally and reversely by a command of the position control amplifier 82 according to the movement amount of the chopper folding device 74. It At this time, the position detection device 64 feeds back the amount of movement of the scored blade 57 to the position control amplifier 82.

【0020】 上記構成の折機の作用を説明する。The operation of the folding machine having the above structure will be described.

【0021】 折り位置の変更等によりハンドル80を回してチョッパ折装置74を移動させ ると、その位置がチョッパ位置検出装置81によって検出される。検出された位 置によりチョッパ折装置74の移動量が求められ、その量を目標値として位置制 御増幅器82によってモータ62に駆動指令が出される。モータ62の駆動によ り、ニッピングローラ52及び筋目付け刃57を有するシャフト54が、チョッ パ折装置74の移動量に応じて軸方向に移動する。ニッピングローラ52及びシ ャフト54の移動位置は位置検出装置64によって検出され、モータ62は、チ ョッパ位置検出装置81と位置検出装置64との検出値の差がなくなったところ で停止する。従って、チョッパ折装置74の移動に伴ない筋目付け刃57の移動 が連動し、両者の位置が一定に保たれる。When the chopper folding device 74 is moved by turning the handle 80 by changing the folding position, the position is detected by the chopper position detecting device 81. The amount of movement of the chopper folding device 74 is obtained from the detected position, and a drive command is issued to the motor 62 by the position control amplifier 82 using this amount as a target value. By driving the motor 62, the shaft 54 having the nipping roller 52 and the scored blade 57 moves in the axial direction according to the movement amount of the chopper folding device 74. The moving positions of the nipping roller 52 and the shaft 54 are detected by the position detecting device 64, and the motor 62 stops when the difference between the detected values of the chopper position detecting device 81 and the position detecting device 64 disappears. Therefore, the movement of the scoring blade 57 is interlocked with the movement of the chopper folding device 74, and the positions of both are kept constant.

【0022】 エラー機能として、モータ62を駆動していても、位置検出装置64の値が変 化しない時、エラーを表示する。As an error function, an error is displayed when the value of the position detection device 64 does not change even if the motor 62 is driven.

【0023】 上記一実施例では、折目付け手段として筋目付け刃57を例に挙げて説明した が、縦ミシン刃を用いることも可能である。In the above-mentioned one embodiment, the creasing means 57 has been described as an example of the creasing means, but it is also possible to use a vertical sewing machine blade.

【考案の効果】[Effect of the device]

本考案の輪転印刷機の折機は、運転中にチョッパ折装置を移動させても、制御 装置によって折目付け手段をチョッパ折装置に連動させて移動させることができ る。この結果、常に折精度の高いチョッパ折が得られると共に、調節時であって もチョッパ折装置と折目付け手段の位置が一致するため折丁は良品となり、運転 を停止することなくチョッパ折装置の移動調節が行なえる。また、作業者による 位置合わせが不要となり、人手による差がなくなり、常に高精度の折りが得られ る。 In the folding machine of the rotary printing press of the present invention, even if the chopper folding device is moved during operation, the control device can move the creasing means in conjunction with the chopper folding device. As a result, chopper folding with high folding accuracy is always obtained, and even when adjusting, the chopper folding device and the creasing means are in the same position, so the signature is good and the chopper folding device can be operated without stopping operation. You can adjust the movement. In addition, the operator does not need to align the position, there is no human difference, and high-precision folding is always possible.
