しかしながら、特許文献１に開示された両面印刷機の検査装置にあっては、紙が第１デリバリーチェーンを通過した後、第１及び第２渡胴上で検査カメラによりその印刷品質が検査されるようになっているので、両面印刷位置から検査位置までの紙の搬送距離が必然的に長くなり、不良紙の発見が遅れてそれだけ第１デリバリーチェーン上に滞留するヤレ紙が増大するという虞があった。   However, in the inspection apparatus of the double-sided printing machine disclosed in Patent Document 1, the print quality is inspected by the inspection cameras on the first and second transfer cylinders after the paper passes through the first delivery chain. As a result, there is a possibility that the paper transport distance from the double-sided printing position to the inspection position will inevitably become longer, and the detection of defective paper will be delayed and the amount of waste paper that stays on the first delivery chain will increase accordingly. there were.

また、第１デリバリーチェーンと第２デリバリーチェーンとの間に、検査装置として専用の第１〜第３渡胴が必要となることから、部品点数の増大で機械が大型化すると共にコストアップを招来するという不具合もあった。   In addition, a dedicated first to third transfer cylinder is required as an inspection device between the first delivery chain and the second delivery chain, which increases the number of parts and increases the cost of the machine. There was also a problem of doing.

以下、本発明に係る両面印刷機の検査装置を実施例により図面を用いて詳細に説明する。   Hereinafter, an inspection apparatus for a double-sided printing machine according to the present invention will be described in detail with reference to the accompanying drawings.

図１は本発明の一実施例を示す４色両面同時印刷オフセット機の要部拡大側面図、図２は同じく本発明の作用時における不具合の一例を示す説明図、図３は同じく４色両面同時印刷オフセット機の全体側面図である。   FIG. 1 is an enlarged side view of an essential part of a four-color double-sided simultaneous printing offset machine showing an embodiment of the present invention, FIG. 2 is an explanatory diagram showing an example of a malfunction during the operation of the present invention, and FIG. It is a whole side view of a simultaneous printing offset machine.

図１及び図３に示すように、４色両面同時印刷オフセット機（両面印刷機）の印刷部１では、紙くわえ（保持）装置（図示せず）を備えているゴム圧胴（第１印刷胴）２と紙くわえ（保持）装置を備えていないゴム胴（第２印刷胴）３とが略水平に支承されており、各々の周面が対接している。また、ゴム胴３がゴム圧胴２の側方に位置して対接し、ゴム圧胴２が排紙部（排出部）１６側に、ゴム胴３が給紙部１５側に配設されている。   As shown in FIGS. 1 and 3, the printing unit 1 of the four-color double-sided simultaneous printing offset machine (double-sided printing machine) has a rubber impression cylinder (first printing) provided with a paper holding (holding) device (not shown). A cylinder 2 and a rubber cylinder (second printing cylinder) 3 not provided with a paper holding (holding) device are supported substantially horizontally, and their peripheral surfaces are in contact with each other. Further, the rubber cylinder 3 is located on the side of the rubber impression cylinder 2 and is in contact therewith, the rubber impression cylinder 2 is disposed on the paper discharge section (discharge section) 16 side, and the rubber cylinder 3 is disposed on the paper feed section 15 side. Yes.

そして、ゴム圧胴２の周面には４つの版胴４が配置され、またゴム胴３の周面にも４つの版胴５が配置されている。これらの版胴４，５に対し接近・離反できるようにインキユニット６，７が移動可能に設けられ、版胴４，５に接した状態でインキや水の供給を行えるようになっている。前記ゴム圧胴２、版胴４、ゴム胴３及び版胴５が紙（シート）Ｗの両面に同時印刷を施す印刷部を構成する。   Four plate cylinders 4 are arranged on the peripheral surface of the rubber cylinder 2, and four plate cylinders 5 are also arranged on the peripheral surface of the rubber cylinder 3. Ink units 6 and 7 are movably provided so as to be able to approach and leave the plate cylinders 4 and 5 so that ink and water can be supplied in contact with the plate cylinders 4 and 5. The rubber impression cylinder 2, the plate cylinder 4, the rubber cylinder 3 and the plate cylinder 5 constitute a printing unit that performs simultaneous printing on both sides of the paper (sheet) W.

また、ゴム圧胴２とゴム胴３の対接箇所である印刷箇所Ｐ１よりもゴム圧胴２の回転方向上流側であるゴム圧胴２の上側には、紙くわえ（保持）装置を備えて、見当部８からゴム圧胴２へ紙Ｗを受け渡す４つの渡胴９〜１２が配設されると共に、印刷箇所Ｐ１よりもゴム圧胴２の回転方向下流側であるゴム圧胴２の下側には、紙くわえ（保持）装置を備えて、ゴム圧胴２から後述するデリバリーチェーン１７へ紙Ｗを受け渡す渡胴１３が設けられる。   Further, a paper holding (holding) device is provided on the upper side of the rubber impression cylinder 2 which is the upstream side in the rotation direction of the rubber impression cylinder 2 with respect to the printing location P1 which is a contact location between the rubber impression cylinder 2 and the rubber cylinder 3. The four transfer cylinders 9 to 12 for delivering the paper W from the register 8 to the rubber impression cylinder 2 are disposed, and the rubber impression cylinder 2 on the downstream side in the rotation direction of the rubber impression cylinder 2 from the printing location P1. On the lower side, a transfer cylinder 13 that includes a paper holding (holding) device and delivers the paper W from the rubber impression cylinder 2 to a delivery chain 17 described later is provided.

前記見当部８へはフィーダーボード１４を介して給紙部（供給部）１５から紙Ｗが供給される一方、前記渡胴１３からは図示しない爪竿（チェーングリッパ）を備えたデリバリーチェーン１７を介して排紙部１６の排紙パイル２１上へ紙Ｗが搬送される。即ち、デリバリーチェーン１７の紙搬送方向上流側のデリバリー胴（排紙胴）１７ａが渡胴１３の下側に対接して当該渡胴１３から紙Ｗが受け渡されるのである。前記渡胴１３及びデリバリーチェーン１７（デリバリー胴１７ａ，１７ｂを含む）が紙（シート）Ｗを保持して排紙部１６へ搬送する搬送手段を構成する。   The registration unit 8 is supplied with paper W from a paper supply unit (supply unit) 15 via a feeder board 14, while the transfer cylinder 13 is provided with a delivery chain 17 having a claw hook (chain gripper) (not shown). Then, the paper W is conveyed onto the paper discharge pile 21 of the paper discharge unit 16. That is, the delivery cylinder (paper discharge cylinder) 17a on the upstream side in the paper conveyance direction of the delivery chain 17 is in contact with the lower side of the transfer cylinder 13, and the paper W is delivered from the transfer cylinder 13. The transfer cylinder 13 and the delivery chain 17 (including the delivery cylinders 17 a and 17 b) constitute a conveying means that holds the paper (sheet) W and conveys it to the paper discharge unit 16.

また、前記デリバリーチェーン１７は、その上流側のデリバリー胴１７ａをゴム圧胴２の下方に配置してゴム圧胴２とゴム胴３との対接箇所の下方空間を横断することなく当該デリバリー胴１７ａよりも排紙部１６側へ図中左方にフロアに沿って配置される。   Further, the delivery chain 17 has a delivery cylinder 17a on the upstream side thereof disposed below the rubber cylinder 2 so that the delivery cylinder 17 does not cross the space below the contact point between the rubber cylinder 2 and the rubber cylinder 3. Arranged along the floor on the left side of the drawing toward the paper discharge unit 16 side from 17a.

図示例では、ゴム圧胴２とゴム胴３とは３倍胴で、４つの渡胴９〜１２と４つの版胴４と４つの版胴５とデリバリー胴１７ａとは１倍胴で、渡胴１３は２倍胴でそれぞれ構成される。   In the illustrated example, the rubber impression cylinder 2 and the rubber cylinder 3 are triple cylinders, the four transfer cylinders 9 to 12, the four plate cylinders 4, the four plate cylinders 5 and the delivery cylinder 17a are single cylinders. The cylinder 13 is composed of a double cylinder.

そして、前記渡胴１３により搬送される紙Ｗの一方の面（表面）の印刷状態を検出する検出手段としての第１検査カメラ２５が、一対の照明器２６と伴に当該渡胴１３の排紙部１６側に位置して、渡胴１３を指向するように斜め上向きに配設される一方、デリバリー胴１７ａにより搬送される紙Ｗの他方の面（裏面）の印刷状態を検出する検出手段としての第２検査カメラ２７が、一対の照明器２８と伴に当該デリバリー胴１７ａの給紙部１５側に位置して、デリバリー胴１７ａを指向するように斜め下向きに配設される。   Then, the first inspection camera 25 as a detecting means for detecting the printing state of one surface (front surface) of the paper W conveyed by the transfer cylinder 13 is connected to the discharge of the transfer cylinder 13 together with the pair of illuminators 26. Detecting means for detecting the printing state of the other surface (back surface) of the paper W conveyed by the delivery cylinder 17a while being disposed obliquely upward so as to be directed to the transfer cylinder 13 and positioned on the paper section 16 side The second inspection camera 27 is located on the paper feed unit 15 side of the delivery cylinder 17a together with the pair of illuminators 28, and is disposed obliquely downward so as to face the delivery cylinder 17a.

前記第１検査カメラ２５（一対の照明器２６も含めて）は、２倍胴からなる渡胴１３の周面において、ゴム圧胴２と渡胴１３との対接箇所（シート受け渡し箇所Ｐ２参照）から本機械で印刷できる最大紙の天地方向長さＬと同じ位置又はＬを越えた位置で、紙Ｗの印刷状態を検査できるように配置されている。尚、第１及び第２検査カメラ２５，２７としては、ＣＣＤ−ラインカメラやＣＣＤ-ラインセンサなどの光学的／電子的撮影装置が採用される。   The first inspection camera 25 (including the pair of illuminators 26) has a contact point between the rubber impression cylinder 2 and the transfer cylinder 13 on the peripheral surface of the transfer cylinder 13 (see the sheet transfer position P2). ) Is arranged so that the printing state of the paper W can be inspected at the same position as the vertical length L of the maximum paper that can be printed by this machine or at a position exceeding L. As the first and second inspection cameras 25 and 27, an optical / electronic photographing apparatus such as a CCD-line camera or a CCD-line sensor is employed.

また、前記ゴム圧胴２におけるゴム胴３との対接箇所（印刷箇所Ｐ１参照）より同ゴム圧胴２の回転方向下流側でかつ渡胴１３との対接箇所（シート受け渡し箇所Ｐ２参照）よりも同ゴム圧胴２の回転方向上流側の周面に対向して同ゴム圧胴２の周面を洗浄する第１ブランケット洗浄装置（洗浄装置）２９が配設されると共に、前記ゴム圧胴２に対接するゴム胴３おけるゴム圧胴２との対接箇所（印刷箇所Ｐ１参照）より同ゴム胴３の回転方向下流側でかつ最下位置の版胴５との対接箇所（インキ供給箇所Ｐ３参照）よりも同ゴム胴３の回転方向上流側の周面に対向して同ゴム胴３の周面を洗浄する第２ブランケット洗浄装置３０が配設される。尚、第１及び第２ブランケット洗浄装置２９及び３０は、印刷が終了したときにゴム圧胴２及びゴム胴３のブランケットにブラシ又は布を接触させてインキを除去する装置である。   In addition, the rubber impression cylinder 2 is located downstream of the rubber impression cylinder 2 in the rotational direction of the rubber cylinder 3 (refer to the printing position P1) and is in contact with the transfer cylinder 13 (see the sheet delivery position P2). A first blanket cleaning device (cleaning device) 29 for cleaning the peripheral surface of the rubber pressure drum 2 is disposed opposite to the peripheral surface upstream of the rubber pressure drum 2 in the rotational direction. The rubber cylinder 3 in contact with the cylinder 2 is in contact with the rubber cylinder 3 (refer to the printing area P1) and the downstream of the rubber cylinder 3 in the rotational direction and with the lowermost plate cylinder 5 (ink). A second blanket cleaning device 30 for cleaning the peripheral surface of the rubber cylinder 3 is disposed opposite the peripheral surface upstream of the rubber cylinder 3 in the rotational direction from the supply location P3). The first and second blanket cleaning devices 29 and 30 are devices that remove ink by bringing a brush or cloth into contact with the blanket of the rubber impression cylinder 2 and the rubber cylinder 3 when printing is completed.

このように構成されるため、給紙部１５から供給されて見当部８によって位置決めされた紙Ｗは、図中矢印で示す経路、即ち、渡胴９〜１２，ゴム圧胴２，渡胴１３，デリバリー胴１７ａの順に各周面に沿って搬送され、ゴム圧胴２とゴム胴３の対接箇所（印刷箇所Ｐ１参照）を上方から下方に向い通過するときにその両面に同時に印刷が施されることになる。   With this configuration, the paper W supplied from the paper supply unit 15 and positioned by the register unit 8 is a path indicated by an arrow in the drawing, that is, the transfer cylinders 9 to 12, the rubber impression cylinder 2, and the transfer cylinder 13. , The delivery cylinder 17a is conveyed along each peripheral surface, and printing is simultaneously performed on both sides of the rubber impression cylinder 2 and the rubber cylinder 3 when passing from the upper side to the lower side (refer to the printing position P1). Will be.

前記印刷後の紙Ｗは、デリバリーチェーン１７によって図３中のデリバリー胴１７ｂへと向けて順次搬送され、排紙部１６の所定の排紙パイル２１上に紙積みされる。   The printed paper W is sequentially conveyed by the delivery chain 17 toward the delivery cylinder 17 b in FIG. 3 and stacked on a predetermined paper discharge pile 21 of the paper discharge unit 16.

そして、本実施例では、紙Ｗが渡胴１３により搬送される時に、その表面の印刷状態が第１検査カメラ２５で検出される一方、紙Ｗがデリバリー胴１７ａにより搬送される時に、その裏面の印刷状態が第２検査カメラ２７で検出される。   In this embodiment, when the paper W is transported by the transfer cylinder 13, the printing state of the front surface is detected by the first inspection camera 25, while when the paper W is transported by the delivery cylinder 17a, the back surface thereof is detected. Is detected by the second inspection camera 27.

この際、渡胴１３においては、第１検査カメラ２５（一対の照明器２６も含めて）が、２倍胴からなる渡胴１３の周面において、ゴム圧胴２と渡胴１３との対接箇所（シート受け渡し箇所Ｐ２参照）から本機械で印刷できる最大紙の天地方向長さＬに達した位置又は若干越えた位置で、紙Ｗの印刷状態が検査される。   At this time, in the transfer cylinder 13, the first inspection camera 25 (including the pair of illuminators 26) has a pair of the rubber impression cylinder 2 and the transfer cylinder 13 on the circumferential surface of the transfer cylinder 13 composed of a double cylinder. The printing state of the paper W is inspected at a position where the maximum paper length L that can be printed by this machine from the contact point (see the sheet transfer point P2) has reached or slightly exceeded.

これにより、紙Ｗの紙尻がゴム圧胴２と渡胴１３との対接箇所（シート受け渡し箇所Ｐ２参照）から完全に抜け出て、紙Ｗの安定した搬送状態下で検査が行われるので、高精度な検査が行える。   As a result, the paper bottom of the paper W completely comes out of the contact location between the rubber impression cylinder 2 and the transfer cylinder 13 (see the sheet delivery location P2), and the inspection is performed under a stable conveyance state of the paper W. High-precision inspection can be performed.

即ち、図２に示すように、紙Ｗの紙尻がゴム圧胴２と渡胴１３との対接箇所（シート受け渡し箇所Ｐ２参照）から抜け出てない場合は、紙Ｗの紙尻側がゴム圧胴２の粘着力によりゴム圧胴２と渡胴１３との対接箇所を通過しても未だゴム圧胴２に付着した状態が生起されるので、紙Ｗの張力が安定しない状態での検査となり、正確な検査が行えないのであるが、本実施例ではそれが回避されるのである。   That is, as shown in FIG. 2, when the paper bottom of the paper W does not come out of the contact position between the rubber impression cylinder 2 and the transfer cylinder 13 (see the sheet delivery position P2), the paper bottom side of the paper W Even when the rubber cylinder 2 and the transfer cylinder 13 pass through the contact portion due to the adhesive force of the cylinder 2, the state still adheres to the rubber cylinder 2 so that the tension of the paper W is not stable. Thus, accurate inspection cannot be performed, but this is avoided in this embodiment.

このようにして本実施例によれば、両面印刷後直ぐに検査を行えるので、不良紙の発生後即機械を停止することができ、無駄に機械の運転を継続してヤレ紙が増大するのを回避することができる。また、渡胴１３やデリバリー胴１７ａ等の既設の胴配列を利用するなどして検査を行えるので、部品点数の削減により機械の大型化を回避することができると共にコストダウンを図ることができる。   In this way, according to the present embodiment, since the inspection can be performed immediately after the double-sided printing, the machine can be stopped immediately after the occurrence of the defective paper, and the machine operation is unnecessarily continued to increase the amount of waste paper. It can be avoided. In addition, since inspection can be performed by using an existing cylinder arrangement such as the transfer cylinder 13 and the delivery cylinder 17a, the size of the machine can be avoided by reducing the number of parts, and the cost can be reduced.

勿論、本実施例では、両面印刷後排紙までの間で両面品質検査をインラインで行えるので、設置スペースや機械全長の増大を招くこともない。   Of course, in this embodiment, the double-sided quality inspection can be performed inline before the paper discharge after double-sided printing, so there is no increase in installation space and overall machine length.

また、本実施例のように、ゴム圧胴２やゴム胴３の周囲に多数の版胴４，５を配置する所謂サテライト型の胴配列においては、ゴム圧胴２やゴム胴３の周面にアクセスできる箇所が限定されるが、紙Ｗに印刷が施されるゴム圧胴２とゴム胴３との対接箇所（印刷箇所Ｐ１参照）とゴム圧胴２と渡胴１３との対接箇所（シート受け渡し箇所Ｐ２参照）との間に当該ゴム圧胴２の周面にアクセスできる箇所（空間）が生じる。   In the so-called satellite type cylinder arrangement in which a large number of plate cylinders 4 and 5 are arranged around the rubber cylinder 2 and the rubber cylinder 3 as in the present embodiment, the peripheral surfaces of the rubber cylinder 2 and the rubber cylinder 3 are arranged. However, the contact position between the rubber impression cylinder 2 and the rubber cylinder 3 where the printing is performed on the paper W (see the printing position P1), and the contact between the rubber impression cylinder 2 and the transfer cylinder 13 is limited. A location (space) where the peripheral surface of the rubber impression cylinder 2 can be accessed is formed between the location (see the sheet delivery location P2).

そこで、本実施例では、上記空間を利用して第１ブランケット洗浄装置（洗浄装置）２９を配置するようにしたので、設計上頗る優位である。即ち、この位置に第１ブランケット洗浄装置（洗浄装置）２９を配置できるのは、第２検査カメラ２７による検査位置をデリバリー胴１７ａに設定したからである。   Therefore, in the present embodiment, the first blanket cleaning device (cleaning device) 29 is arranged using the space, which is advantageous in terms of design. That is, the first blanket cleaning device (cleaning device) 29 can be disposed at this position because the inspection position by the second inspection camera 27 is set to the delivery cylinder 17a.

尚、本発明は上記実施例に限定されず、本発明の要旨を逸脱しない範囲で、胴配列やインキ色の変更等各種変更が可能であることはいうまでもない。   Needless to say, the present invention is not limited to the above-described embodiments, and various changes such as changes in the cylinder arrangement and ink color are possible without departing from the scope of the present invention.

本発明に係る両面印刷機の検査装置は、品質管理が重要な証券印刷等に用いて有効である。   The inspection apparatus for a double-sided printing machine according to the present invention is effective for use in securities printing or the like where quality control is important.
