本考案は印刷機の版胴に設けられ胴周面に巻付けられる版のくわえ側と尻側と を固定する版万力装置に関するものである。 This invention is installed on the plate cylinder of a printing press, and the grip side and tail side of the plate are wrapped around the cylinder circumferential surface. This relates to a plate vise device that fixes the plate.
【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長方形状の切欠きが 設けられており、この切欠き内には、版のくわえ側端部をくわえるくわえ側版万 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、切欠き底面に固定されて胴軸方向に延設され ている。 On the outer periphery of the plate cylinder of various printing presses, there is a notch with a rectangular cross section that spans the entire length of the cylinder. Inside this notch is a gripper-side plate that holds the gripper-side end of the plate in its mouth. The force and the butt that holds the butt end of the plate that is wrapped around the circumference of the torso. A plate vise device consisting of a side plate vise is fixed to the bottom of the notch and extends in the axial direction of the cylinder. ing.
【０００３】 従来におけるこれらくわえ側，尻側の版万力は、胴軸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を備えており、これらくわえ板の近傍 には、これと係合する複数個のカムを備えたくわえ側カム軸と尻側カム軸とが胴 軸方向に延設されている。そして、装置がスプリングクローズ式の場合、くわえ 板と万力台との間には、くわえ板を万力台に対し閉じる方向に付勢する圧縮コイ ルばねが介装されている。さらに、尻側版万力には、これを版張り方向に付勢す る圧縮コイルばねを備えた版張り装置が設けられている。0003 These conventional grip-side and butt-side plate vises are long vises that extend in the axial direction of the body. Between the stand and the vise stand, which is rotatably supported on the vise stand side and opens and closes by rotation. It is equipped with a gripping board for holding and releasing the plate, and the area near these gripping boards is The gripper side camshaft and the buttside camshaft, which have multiple cams that engage with the gripper side camshaft, are attached to the body. It extends in the axial direction. If the device is a spring-close type, A compression coil is placed between the plate and the vise table to bias the grip plate in the direction of closing the vise table. A spring is inserted. Furthermore, the bottom side plate vise is biased in the direction of plate tension. A plate tensioner is provided with a helical compression spring.
【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、手動または駆 動装置でくわえ側カム軸を回動させると，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て開くので、くわえ板と万力台とのくわえ面間へ版の端を挿 入したのち、カム軸を先程とは逆方向へ回動させると、くわえ板はカムの作用か ら開放され、圧縮コイルばねの弾発力によって閉じ、版の端をくわえる。そこで 版胴をほゞ１回転させると、版が胴周面に巻付けられるので、先程と同様にして 尻側の版万力で版の尻側端部をくわえさせたのち、版張り装置により尻側版万力 を胴周方向へ移動させると、版が張られて胴周面に密着する。0004 With this configuration, when adding the plate, you can manually or manually load the plate. When the gripping side camshaft is rotated by the motion device, the gripping plate is compressed by the compression coil due to the action of the cam. It opens against the elastic force of the spring, so insert the edge of the plate between the gripping surfaces of the gripping plate and vice stand. When the camshaft is rotated in the opposite direction to the previous direction, the gripping plate will be moved by the action of the cam. It is opened from the top and closed by the elastic force of the compression coil spring, gripping the edge of the plate. Therefore When the plate cylinder is rotated approximately once, the plate is wrapped around the cylinder, so do the same as before. After gripping the butt end of the plate with the butt side plate vise, the plate tensioning device holds the butt side edge of the plate in the butt side plate vise. When the is moved in the circumferential direction, the plate is stretched and comes into close contact with the circumferential surface of the trunk.

ところで、このような版万力装置において、版を装着したのちに版の焼きや印 刷紙の伸び等によって版の印刷見当が天地方向にずれた場合には、版の尻側端部 を版の幅方向複数箇所で天地方向へ伸縮させる必要がある。しかしながら、前記 従来の装置においてはこの場合、版を版くわえ方向および版張り方向に弾発する 前記圧縮コイルばねの強さを調整していたので、多数の圧縮コイルばねを調整す ることは多大の労力と長時間を要するばかりでなく、圧縮コイルばねのばね力に 限界があって強く張ることができず、調整が不充分になるという問題がある。 By the way, in such a plate vise device, after the plate is installed, the plate cannot be burned or stamped. If the printing register of the plate shifts in the vertical direction due to elongation of the printing paper, etc., the bottom edge of the plate It is necessary to expand and contract the plate in the vertical direction at multiple locations across the width of the plate. However, the In this case, in conventional devices, the plate is ejected in the plate gripping direction and the plate tensioning direction. Since we were adjusting the strength of the compression coil springs mentioned above, we had to adjust a large number of compression coil springs. Not only does it take a lot of effort and a long time to do this, but the spring force of the compression coil spring There is a problem that there is a limit and it cannot be tightened strongly, resulting in insufficient adjustment.

Since the plate 40 swings using the cam surface contacting part of a as a fulcrum, the butt part of the plate 40 locally touches the plate 40. The print register is adjusted by moving in the vertical direction.
【００１９】 また、分割された左右の万力台２５間に設けられた連結金具２６のピン孔にス パナ２８を挿入して連結金具２６を回動させると、連結金具２６の両端部に設け られた右ねじと左ねじとの作用により左右の万力台２５がくわえ板２９を伴って 互いに近づいたり離れたりするように逆方向に移動するので、版４０は、尻側端 部のみが幅方向に伸縮する。[0019] In addition, the pin holes of the connecting fittings 26 provided between the left and right vise stands 25 are inserted. When the pannier 28 is inserted and the connecting fitting 26 is rotated, the Due to the action of the right-hand screw and left-hand screw, the left and right vice stands 25 are moved together with the grip plate 29. Since the plates 40 move in opposite directions, approaching and moving away from each other, the plates 40 Only the section expands and contracts in the width direction.
【００２０】 なお、本実施例においては、分割された尻側版万力２０にそれぞれ２個ずつの 版張りボルト３６を設けた例を示したが、１個ずつ設けてもよいし、３個以上ず つ設けてもよい。また、本実施例では万力台２５の遊端部を押す押圧部材として 版張りボルト３６を例示したが、例えばカム等で押すようにしてもよい。さらに 本実施例では、版４０を人手で版万力装置に供給する装置に本考案を実施した例 を示したが、版の供給のみを自動的に行う半自動式の装置や、版の供給，取外し を自動的に行う全自動式の装置にも同様に実施することができ、同様の効果が得 られる。[0020] In addition, in this embodiment, each of the divided butt side vise 20 has two pieces. Although an example is shown in which plate tension bolts 36 are provided, they may be provided one by one, or three or more may be provided at a time. One may be provided. In addition, in this embodiment, it is used as a pressing member that presses the free end of the vice stand 25. Although the plate tension bolt 36 is shown as an example, it may be pushed by a cam or the like, for example. moreover In this example, the present invention is implemented in a device that manually feeds a plate 40 to a plate vise device. However, there are semi-automatic devices that only automatically feed the plate, and devices that feed and remove the plate. The same effect can be obtained by using fully automatic equipment that automatically performs It will be done.
