Abstract
Description
本発明はオフセット印刷機に関し、特に、版胴に巻回される刷版の装着を確認する装置に関する。 The present invention relates to an offset printing machine, and more particularly to an apparatus for confirming mounting of a printing plate wound around a plate cylinder.
オフセット印刷にあっては、版胴に巻回された刷版にインキ及び湿し水を供給し、版面に形成された絵柄を一旦ブランケット胴に転移させた上で、圧胴との間でシートに絵柄が転写されていく。
従って、刷版が版胴に的確に装着されていることが、良好かつ安定した印刷作業の前提となる。
In offset printing, ink and fountain solution are supplied to the printing plate wound around the plate cylinder, the pattern formed on the plate surface is once transferred to the blanket cylinder, and then the sheet is transferred to the impression cylinder. The design is transferred to
Therefore, it is a precondition for a good and stable printing operation that the printing plate is accurately mounted on the plate cylinder.
従前は、人手によって刷版の装着作業を遂行しており、作業者が刷版の装着状態を目視で確認することができた。
けれども、近時は刷版の装着作業を自動化若しくは半自動化する動きが拡がっており、また、印刷機のコンパクトな設計のために、目視確認のための十分なスペースを確保することが困難となってさえいる。
Previously, plate mounting work was performed manually, and the operator was able to visually confirm the mounting state of the plate.
However, recently, the movement to automate or semi-automate the plate mounting work has expanded, and due to the compact design of the printing press, it has become difficult to secure sufficient space for visual confirmation. Even.
特許文献１には、版胴に巻回される刷版のくわえ元側（前端部）のみならずくわえ尻側（後端部）をも様々なセンサによって検知する技術が提案されている。
しかしながら、この従来技術は、刷版の装着作業の全過程を見渡した検知のためのロジックや作動手順には到っていない。
However, this conventional technique has not yet reached the logic and operation procedure for detection overlooking the entire process of mounting the printing plate.
本発明は上記した問題に鑑みてなされ、進歩した刷版の装着確認装置を提供するもので、その目的は、簡易かつ確実に確認作業を行なえるようにすることにある。 The present invention has been made in view of the above-described problems, and provides an advanced plate mounting confirmation device, and an object of the present invention is to enable simple and reliable confirmation work.
そしてこのために、本発明に係る装着装置にあっては、刷版のくわえ元側検出回路（７）がＡ接点（６）として構成され、また、くわえ尻側検出回路（１０）はＢ接点（９）として構成され、機体側の検出回路（１１）との信号伝送が対を成す非接触型スイッチ（１２）によって行なわれることを特徴としている。 For this reason, in the mounting apparatus according to the present invention, the holding plate side detection circuit (7) of the printing plate is configured as the A contact (6), and the holding bottom side detection circuit (10) is configured as the B contact. (9) is characterized in that signal transmission with the detection circuit (11) on the airframe side is performed by a non-contact type switch (12) forming a pair.
このように構成したことにより、自動若しくは半自動による刷版装着の作動手順と連係した上で、刷版のくわえ元側及びくわえ尻側の装着確認が簡易かつ確実に行なえることとなる。 With this configuration, it is possible to easily and reliably check the attachment of the holding plate side and the holding edge side of the printing plate in cooperation with the operation procedure of automatic or semi-automatic plate loading.
版胴（２）のくわえ元側クランプ装置（３）では、ボールプランジャによるくわえ元センサ（５）と連動するＡ接点（６）がくわえ元側検出回路（７）を構成しており、また、くわえ尻側版クランプ装置（４）では、プッシュプランジャによるくわえ尻センサ（８）と連動するＢ接点（９）がくわえ尻側検出回路（１０）を構成しており、機体側の検出回路（１１）との間の信号伝送は対を成す非接触型スイッチ（１２）によって行なわれる。 In the gripper side clamping device (3) of the plate cylinder (2), the A contact (6) interlocked with the gripper source sensor (5) by the ball plunger constitutes the gripper side detection circuit (7). In the gripper side plate clamping device (4), the B contact (9) interlocked with the gripper butterfly sensor (8) by the push plunger constitutes the gripper butterfly side detection circuit (10), and the fuselage side detection circuit (11 The signal transmission between the two is performed by a pair of contactless switches (12).
刷版装着作業における版胴（２）の回転と同期をとりつつ、くわえ元側の装着確認は、刷版の装着押圧に基づくＡ接点（６）のメーク（Ｂ接点（９）もメーク状態）、また、くわえ尻側の装着確認はＢ接点（９）のブレーク（Ａ接点（６）はメーク状態）の状態で、検出回路（１１）により検出される。 While making the rotation of the plate cylinder (2) in the printing plate mounting operation, the mounting confirmation on the gripper side is made by making the A contact (6) based on the pressing pressure of the printing plate (the B contact (9) is also in the make state). In addition, the attachment confirmation on the side of the mouth end is detected by the detection circuit (11) in the state of the break of the B contact (9) (the A contact (6) is in the make state).
以下、図面を参照して、本発明に係る刷版の装着確認装置の一実施例につき詳細に説明する。
図１は、装着確認装置の概念説明図、図２は、装着確認装置を備えた版胴の概要を示す平面図である。

印刷機のサイドフレーム（１）間に回転自在に支承された版胴（２）は、その外周凹部に１対のくわえ元側版クランプ装置（３）及びくわえ尻側クランプ装置（４）を有しており、起倒制御されるくわえプレートによって金属製ないしはプラスチック等の刷版の端部を咬持することは十分に知られている。 The plate cylinder (2) rotatably supported between the side frames (1) of the printing press has a pair of gripper side plate clamp devices (3) and a gripper edge side clamp device (4) in its outer peripheral recess. It is well known that the end of a printing plate such as metal or plastic is held by a holding plate that is controlled to be raised and lowered.
版胴（２）のくわえ元側版クランプ装置（３）にあっては、刷版装着時の押圧によって作動されるボールプランジャによるくわえ元センサ（５）及びこれと連動するＡ接点（６）が設けられ、くわえ元側検出回路（７）を構成している。
また、これと対を成してくわえ尻側版クランプ装置（４）では、プッシュプランジャによるくわえ尻センサ（８）及びこれと連動するＢ接点（９）が設けられ、くわえ尻側検出回路（１０）を構成している。
そして、回転する版胴（２）から絶対静止の機体側の検出回路（１１）との間で信号伝送を行なうため、静電容量形、超音波形等の近接スイッチによる１対の非接触型スイッチ（１２）が設けられている。
なお、検出回路（１１）は更に、印刷機全体を制御する制御コンソールと連結されることは無論である。
In the gripper side plate clamp device (3) of the plate cylinder (2), a gripper source sensor (5) by a ball plunger that is actuated by pressing during mounting of the printing plate and an A contact (6) interlocked therewith are provided. It is provided and constitutes the holding side detection circuit (7).
In addition, the tail edge plate clamping device (4) which is paired with this is provided with a mouth edge sensor (8) by a push plunger and a B contact (9) interlocked therewith, and a mouth edge side detection circuit (10 ).
In order to perform signal transmission between the rotating plate cylinder (2) and the absolute stationary airframe side detection circuit (11), a pair of non-contact type by a proximity switch such as a capacitance type or an ultrasonic type. A switch (12) is provided.
It goes without saying that the detection circuit (11) is further connected to a control console for controlling the entire printing press.
次に、図３のフローチャートを参照して、上記構成の作用を説明する。
刷版の装着作業が開始されると、版胴（２）は装着作業に適した基準位置で停止される（ステージ１（Ｓ−１））。
そして、自動若しくは半自動の装着装置によって刷版の先端がくわえ元側クランプ装置（３）に挿入されると（ステージ２（Ｓ―２））、くわえ元センサ（５）が作動し、くわえ元側検出回路（７）のＡ接点（６）をメークする。この時、くわえ尻側検出回路（１０）のＢ接点（９）は導通しているので、検出信号が非接触型スイッチ（１２）を経由して、機体側の検出回路（１１）に送出される（ステージ３（Ｓ−３））。なお、以上の手順に不具合がある場合には、警告表示がなされ（ステージ３１（Ｓ−３１））、作業がやり直される。
Next, the operation of the above configuration will be described with reference to the flowchart of FIG.
When the plate mounting operation is started, the plate cylinder (2) is stopped at a reference position suitable for the mounting operation (stage 1 (S-1)).
Then, when the front end of the printing plate is inserted into the gripper side clamping device (3) by the automatic or semi-automatic mounting device (stage 2 (S-2)), the gripper source sensor (5) is activated, and the gripper side Make the A contact (6) of the detection circuit (7). At this time, since the B contact (9) of the gripper end detection circuit (10) is conductive, a detection signal is sent to the detection circuit (11) on the airframe side via the non-contact switch (12). (Stage 3 (S-3)). If there is a problem with the above procedure, a warning is displayed (stage 31 (S-31)) and the operation is repeated.
くわえ元側の装着完了の信号が検出回路（１１）によって検知されると、くわえ元側クランプ装置（３）が閉じられ（ステージ４（Ｓ−４））、版胴（２）が回転されて、その外周に刷版が徐々に巻き付けられる（Ｓ−５））。 When a detection completion signal is detected by the detection circuit (11), the gripper side clamp device (3) is closed (stage 4 (S-4)) and the plate cylinder (2) is rotated. The printing plate is gradually wound around the outer periphery (S-5)).
この後、版胴（２）は刷版の後端装着位置で停止され、くわえ尻側検出回路（１０）では、刷版の押圧により、くわえ尻センサ（８）と連動してＢ接点（９）がブレークされる。しかし、この時非接触型スイッチ（１２）が相対向する位相ではないので、信号の送出ははされない（ステージ６（Ｓ−６））。 Thereafter, the plate cylinder (2) is stopped at the position where the rear end of the printing plate is mounted, and the gripper edge side detection circuit (10) interlocks with the gripper edge sensor (8) by the press of the printing plate to contact the B contact (9 ) Is broken. However, at this time, since the non-contact type switch (12) is not in a phase opposite to each other, no signal is transmitted (stage 6 (S-6)).
版胴側及び機体側の非接触型スイッチ（１２）を対向位置に合わせるため、版胴（２）が回転され（ステージ７（Ｓ−７））、対向位置でＢ接点（９）がブレークされている信号が送出されて（ステージ８（Ｓ−８））、くわえ尻側の装着作業が完了する。なお、後端の装着作業に不具合がある場合にも、警告表示がなされ（ステージ８１（Ｓ−８１））、作業がやり直される。 The plate cylinder (2) is rotated (stage 7 (S-7)) in order to set the non-contact type switch (12) on the plate cylinder side and the machine body side to the facing position, and the B contact (9) is broken at the facing position. Is transmitted (stage 8 (S-8)), and the mounting work on the mouth end side is completed. In addition, even when there is a defect in the rear end mounting operation, a warning is displayed (stage 81 (S-81)) and the operation is repeated.
本発明に係る刷版の装着確認装置によれば、非常に簡易な構成のもとで、装着手順を的確に確認することができ、印刷前準備作業の能率向上に大きく資することができる。 According to the plate mounting confirmation apparatus according to the present invention, the mounting procedure can be accurately confirmed with a very simple configuration, which can greatly contribute to the improvement of the efficiency of the pre-printing preparation work.
