Description
【０００１】[0001]
本考案は印刷機において、版胴の周面に対向させて機体側の保持装置に保持さ せた刷版を、版胴の版万力にくわえさせて装着する版胴への刷版装着装置に関す るものである。 The present invention is a printing plate loading device for a printing press, in which a printing plate held by a holding device on the machine body facing the peripheral surface of the printing cylinder is held by a plate vise of the printing cylinder and mounted in a printing press. It is related to.
【０００２】[0002]
各種印刷機の版胴外周部には、胴の全長におよぶ断面ほゞ扇形状の切欠きが設 けられており、この切欠き内には、刷版（以下、単に版という）のくわえ側端部 を固定するくわえ側版万力と、これにくわえられたのち胴周面に巻付けられた版 の尻側端部をくわえる尻側版万力とからなる版万力装置が、切欠きの底面に固定 されて版胴の軸線方向に延設されている。 On the outer periphery of the plate cylinder of various printing machines, there is a notch with a cross-section that extends over the entire length of the cylinder, and the inside of this notch is on the grip side of the printing plate (hereinafter simply referred to as the plate). A plate vise device consisting of a gripping plate vise that fixes the end part and a bottom plate vise that holds the end part of the plate wrapped around the body after being gripped by this, is a notch. It is fixed to the bottom of the plate and extends in the axial direction of the plate cylinder.
【０００３】 従来におけるこれらくわえ側，尻側の版万力は、版胴の軸線方向に延びる長尺 の万力台と、この万力台側に回動自在に支持されその回動により開閉して万力台 との間で版をくわえたり放したりするくわえ板と、これらくわえ板の端縁部切欠 きと係合する複数個のカムとを備えており、複数個のカムは回動自在なカム軸上 に並列して固定されている。また、万力台とくわえ板との間には、くわえ板を開 方向に付勢する複数個の圧縮コイルばねが介装されている。Conventionally, these gripper side and butt side plate vises are a long vise base extending in the axial direction of the plate cylinder, and are supported rotatably on the vise base side to open and close by the rotation. The gripper plate holds and releases the plate to and from the vise base and the cams that engage with the notches on the edge of the gripper plates. It is fixed in parallel on the camshaft. A plurality of compression coil springs that urge the holding plate in the opening direction are interposed between the vise base and the holding plate.
【０００４】 このように構成されていることにより、版をくわえる場合には、カム軸を回動 操作すると、版胴の軸線方向へ複数個に分割されたくわえ板は、カムの係合から 開放されて圧縮コイルばねの弾発力によりいっせいに開くので、くわえ板と万力 台との間へ版の端を挿入したのち、カム軸を先程とは逆方向に回動させると、く わえ板はカムの作用で圧縮コイルばねの弾発力に抗し回動して閉じ、版の端をく わえる。With this configuration, when the plate is gripped, when the cam shaft is rotated, the gripper plate divided into a plurality in the axial direction of the plate cylinder is released from the engagement of the cam. Since the elastic force of the compression coil spring opens all at once, insert the end of the plate between the gripper plate and the vise base, and then rotate the cam shaft in the opposite direction to the gripper plate. By the action of the cam, it rotates and closes against the elastic force of the compression coil spring and holds the edge of the plate.
【０００５】 また、例えば特開平１−１２７３４６号公報に開示されている装置は、従来版 胴の円周方向に形成されていた版の尻側くわえ面が、版胴の半径方向に形成され るように、万力台とくわえ板とが版胴の半径方向に延設されており、また、版の 端部が、別に設けた版曲げ機によって直角状に曲げられている。このように構成 されていることにより、くわえ側端部をくわえられて胴周面に巻付けられた版の 尻側端部は、折曲げ部を万力台とくわえ板との間へ挿入され、カム機構でくわえ 板を揺動させることにより、版の折曲げ端がくわえられるので、このあと、尻側 版万力全体を円周方向へ移動させることにより、版万力が均一に張られて胴周面 に密着する。Further, for example, in the apparatus disclosed in Japanese Patent Laid-Open No. 1-127346, the rear side gripping surface of the plate, which was conventionally formed in the circumferential direction of the plate cylinder, is formed in the radial direction of the plate cylinder. As described above, the vise base and the gripper plate are extended in the radial direction of the plate cylinder, and the end of the plate is bent at a right angle by a separately provided plate bending machine. With this structure, the tail end of the plate, which is gripped at the gripper end and wrapped around the body circumference, has the bent part inserted between the vise base and the gripper plate. By swinging the gripping plate with the cam mechanism, the bent edge of the plate can be gripped.After that, by moving the entire butt plate vice in the circumferential direction, the plate vice is evenly stretched. Close to the body.
【０００６】 しかしながら、このような版装着装置においては、くわえ側版万力の狭い開口 部に版万力を挿入するのが難しく、長時間と多大の労力を必要とするばかりでな く、胴周に巻付けながら尻側版万力へ導く版が版胴の周面に密着しないために、 ほゞ直角に折曲げられている版尻を尻側版万力の開口部に挿入するのが難しく、 さらに時間がかかり労力の負担が増大するという問題がある。However, in such a plate mounting apparatus, it is difficult to insert the plate vise into the narrow opening of the plate-side plate vise, which not only requires a long time and a lot of labor, but also causes Since the plate that guides to the butt plate vise while winding it around the circumference does not adhere to the peripheral surface of the plate cylinder, it is recommended to insert the plate butt bent at a right angle into the opening of the butt plate vise. There is a problem that it is difficult, takes more time, and the burden of labor increases.
【０００７】 そこで従来、版胴の周面側である例えば印刷ユニット間の空間部に版を保持す る保持装置を設け、この保持装置で版を保持させながら版のくわえ側版万力への 版の挿入と、版胴周面への版の巻付けとを行ったのち、保持装置の保持から解放 させた版の尻側端部を尻側版万力にくわえさせるようにした半自動式の刷版装着 装置が提案されている。Therefore, conventionally, a holding device for holding the plate is provided in the space on the peripheral surface side of the plate cylinder, for example, in the space between the printing units, and the holding device holds the plate and holds the plate on the holding side plate vise. After the plate has been inserted and the plate has been wrapped around the plate cylinder surface, a semi-automatic version of the semi-automatic type has been adopted in which the rear end of the plate released from the holding of the holding device is held in the rear plate vise. A plate mounting device has been proposed.
【０００８】[0008]
しかしながら、このような従来の半自動式刷版装着装置は、版のくわえ側端部 にＵ字状の切込みを設け、くわえ側版万力には、この切込みと係合する基準ピン を設けたものであって、版万力の装着に際しては、版の端に手を添えて版万力に 挿入し、基準ピンと切込みとを係合させながら版万力を閉じさせるものであるた め、版万力を閉じるときに切込みの底部が基準ピンから離れたり、最初から切込 みの底部が基準ピンに当っていなかったりすることがあって、版万力の装着位置 が不正確になり、印刷見当が狂って印刷物の品質が低下するという問題がある。 However, such a conventional semi-automatic plate mounting device is one in which a U-shaped notch is provided at the edge of the gripper side of the plate and a reference pin that engages with this notch is provided at the gripper of the gripper side. However, when mounting the plate vise, the hand of the plate is put into the plate vise, and the plate vise is closed while the reference pin and the notch are engaged. When closing the force, the bottom of the notch may separate from the reference pin, or the bottom of the notch may not touch the reference pin from the beginning, which causes the plate vise to be installed inaccurately and the printing register. However, there is a problem that the quality of the printed matter deteriorates due to the error.
【０００９】 本考案は以上のような点に鑑みなされたもので、刷版を所定の位置へ容易に高 精度で装着することを可能にした版胴への刷版装着装置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 an object of the present invention to provide a printing plate mounting apparatus for a plate cylinder that enables a printing plate to be mounted easily at a predetermined position with high accuracy. The purpose is.
【００１０】[0010]
このような目的を達成するために本考案では版胴への刷版装着装置において、 上端部を機体側に支持されて垂下され上下方向に開閉自在な安全カバーと、この 安全カバーの表面上端部に固定された版保持部材と、前記安全カバーの表面下端 部に突設された版受けと、前記安全カバーの表面の左右両端部に突設された第１ 版ガイドと、版胴に近接して左右のフレーム側に支持された左右一対の第２版ガ イドとを設けた。 In order to achieve such an object, according to the present invention, in a plate mounting apparatus for a plate cylinder, an upper end is supported by a machine body and hangs down, and a safety cover that can be opened and closed vertically is provided. The plate holding member fixed to the safety cover, the plate receiver projecting from the lower end of the surface of the safety cover, the first plate guides projecting from the left and right ends of the surface of the safety cover, and the plate cylinder. And a pair of left and right second edition guides supported on the left and right frame sides.
