まず、図１〜１１を参照して、円筒状に成形された印刷用版１を版胴２の外周に挿入するための版装着装置について説明する。   First, a plate mounting apparatus for inserting a printing plate 1 formed in a cylindrical shape into the outer periphery of a plate cylinder 2 will be described with reference to FIGS.

以降では、図６，１１に示す版装着治具１０，２０の上下を上下とし、同図の左側を先端、右側を後端として説明する。   Hereinafter, the upper and lower sides of the plate mounting jigs 10 and 20 shown in FIGS. 6 and 11 will be described as the upper and lower sides, the left side of FIG.

また、図８に示す印刷用版１及び版胴２の上下を上下とし、同図の右側を前面、左側を後面として説明する。   Further, the upper and lower sides of the printing plate 1 and the plate cylinder 2 shown in FIG.

版装着装置は、印刷対象物に対して印刷を行う印刷機、印刷機に用いられる印刷用版１に対して印刷模様を彫刻する彫刻機に共通して備えられるものである。   The plate mounting apparatus is commonly provided in a printing machine that performs printing on a printing object and a engraving machine that engraves a printing pattern on a printing plate 1 used in the printing machine.

版胴２に装着される印刷用版１としては、円筒状に形成された印刷用版１、特に、小径の印刷用版１が用いられる。   As the printing plate 1 mounted on the plate cylinder 2, a printing plate 1 formed in a cylindrical shape, particularly a printing plate 1 having a small diameter is used.

印刷される被印刷物は飲料用金属缶であり、特にアルミニウム又はアルミニウム合金製の平板を、ドロー＆アイアニング（ＤＩ）成形した有底円筒状の飲料用金属缶が好適に印刷される。   The substrate to be printed is a beverage metal can, and in particular, a bottomed cylindrical beverage metal can formed by drawing and ironing (DI) a flat plate made of aluminum or an aluminum alloy is suitably printed.

版装着装置は、印刷機の機枠から前方に突出するように設けられた図示しない版駆動軸と、版駆動軸の先端部側から嵌め込まれて、版駆動軸の外周面に固定される版胴２と、を備えている。   The plate mounting device includes a plate drive shaft (not shown) provided so as to protrude forward from the machine frame of the printing press, and a plate that is fitted from the tip end side of the plate drive shaft and is fixed to the outer peripheral surface of the plate drive shaft. And a torso 2.

版胴２は、円筒状に形成され、版駆動軸が挿通させられる挿通孔がその中心に設けられている。   The plate cylinder 2 is formed in a cylindrical shape, and an insertion hole through which the plate drive shaft is inserted is provided at the center thereof.

版胴２の外周には、版駆動軸と同心の円筒状の版装着面２２が形成されており、版装着面２２には、後述する印刷用版１が着脱可能に設けられる。   A cylindrical plate mounting surface 22 concentric with the plate drive shaft is formed on the outer periphery of the plate cylinder 2, and a printing plate 1 described later is detachably provided on the plate mounting surface 22.

版胴２は、重量軽減のために内部が取り除かれて空洞になっており、外周に版装着面２２が形成された円筒部と、を備えている。   The plate cylinder 2 includes a cylindrical portion that is hollowed out to reduce weight and has a plate mounting surface 22 formed on the outer periphery.

版胴２は、挿通孔に版駆動軸を嵌め合わせた状態で版駆動軸に固定され、版駆動軸と一体となって回転する。   The plate cylinder 2 is fixed to the plate drive shaft with the plate drive shaft fitted in the insertion hole, and rotates integrally with the plate drive shaft.

版装着面２２は、装着された印刷用版１の内面との摩擦抵抗による固定力を確保するため、その表面粗さはＲａ１μｍ以下程度で静摩擦を保つことが望ましい。   The plate mounting surface 22 preferably maintains static friction with a surface roughness of about Ra 1 μm or less in order to secure a fixing force due to frictional resistance with the inner surface of the mounted printing plate 1.

また、その表面粗さを小さく保ち、かつ表面に傷が付きにくい点を考慮すると、版装着面２２は、ハードクロム塗装（メッキ）することが好ましい。   Further, considering that the surface roughness is kept small and the surface is hardly damaged, it is preferable that the plate mounting surface 22 be hard chrome coated (plated).

版胴２は、その前面が開口した状態になっており、前面側へ行くほど版装着面２２の径よりも徐々に小径に形成された案内部２７が前面側に設けられている。   The plate cylinder 2 has an open front surface, and a guide portion 27 is formed on the front surface side so as to gradually become smaller in diameter than the diameter of the plate mounting surface 22 toward the front surface side.

For example, a commercially available tin plate (Fe) is adopted, and the thickness of the sheet can be formed in a cylindrical shape. In this example, the thickness is about 0.26 mm.

版本体１１には、版部１２となる樹脂層がその片面に形成されており、この樹脂層は、例えばポリビニルアルコール系、ビニルエステル系またはポリアミド系等の樹脂を採用することができ、ショアＤ硬度で例えば硬化後Ｄ２０〜８０程度のものが好適である。   The plate body 11 is formed with a resin layer to be the plate portion 12 on one side, and this resin layer can employ, for example, a resin such as polyvinyl alcohol, vinyl ester, or polyamide. For example, a hardness of about D20 to 80 after curing is suitable.

例えば、通常のオフセット印刷用のＵＶ硬化樹脂（紫外線硬化樹脂）を採用すると、それ以外の硬化樹脂のような溶剤や高圧スチームによる煩雑な洗浄作業を必要とせず、一般に水洗浄で容易に洗浄作業を行うことができる。   For example, if a UV curable resin (ultraviolet curable resin) is used for normal offset printing, it does not require complicated cleaning work with other solvents such as curable resin or high-pressure steam. It can be performed.

樹脂層の厚さは、印刷の版部１２として必要な厚みがあればよく、この例では、弾性材料製シートの片面に厚さ０．４〜０．６ｍｍの層を接着させている。   The resin layer only needs to have a thickness necessary for the printing plate portion 12. In this example, a layer having a thickness of 0.4 to 0.6 mm is bonded to one side of the elastic material sheet.

円筒状に形成された印刷用版１は、版胴２の前面側から嵌め込まれることによって、版胴２の外周面である版装着面２２に装着される。   The printing plate 1 formed in a cylindrical shape is mounted on the plate mounting surface 22 which is the outer peripheral surface of the plate cylinder 2 by being fitted from the front side of the plate cylinder 2.

印刷用版１の版部１２は、印刷用版１が版胴２に装着されたときに版装着面２２に密着する版本体１１の外面部分に形成されている。   The plate portion 12 of the printing plate 1 is formed on the outer surface portion of the plate body 11 that is in close contact with the plate mounting surface 22 when the printing plate 1 is mounted on the plate cylinder 2.

成形された印刷用版１の軸方向長さ寸法は、版胴２の軸方向長さ寸法よりも短い寸法に設定される。   The axial length dimension of the formed printing plate 1 is set to be shorter than the axial length dimension of the plate cylinder 2.

印刷用版１は、両端部を重ね合わせて接合された部位が、後述する版胴２の版固定部材装着面２３の形成された位置に合わせて版胴２に装着されるようになっている。   The printing plate 1 is mounted on the plate cylinder 2 in accordance with a position where a plate fixing member mounting surface 23 of the plate cylinder 2 to be described later is formed. .

版胴２には、円筒部の一部が取り除かれて、平坦な面が形成されてなる版固定部材装着面２３が設けられており、円筒部の外周の版固定部材装着面２３を除く部分が印刷用版１の装着される版装着面２２となっている。   The plate cylinder 2 is provided with a plate fixing member mounting surface 23 in which a part of the cylindrical portion is removed to form a flat surface, and a portion excluding the plate fixing member mounting surface 23 on the outer periphery of the cylindrical portion.

内輪平坦部４１と印刷用版１の接合部１３とが同位置で嵌め合わされるように形成されているので、印刷用版１を版装着治具１０に案内させ易い。   Since the inner ring flat portion 41 and the joining portion 13 of the printing plate 1 are formed to be fitted at the same position, the printing plate 1 can be easily guided to the plate mounting jig 10.

この状態で、本体外輪３の係合凸部５１に印刷用版１の係合凹部１５が嵌るように、本体内輪４の外周面で支持させる、即ち、印刷用版１を版装着治具１０に装着する。   In this state, the printing plate 1 is supported on the outer peripheral surface of the main body inner ring 4 so that the engagement concave portion 15 of the printing plate 1 fits into the engagement convex portion 51 of the main body outer ring 3. Attach to.

これにより、周方向に位置決めされた本体外輪３及び本体内輪４が、印刷用版１と周方向に位置決めされた状態となる。   Thereby, the main body outer ring 3 and the main body inner ring 4 positioned in the circumferential direction are positioned in the circumferential direction with the printing plate 1.

印刷用版１を版装着治具１０に固定させた状態で、版装着治具１０を版胴２に嵌め込ませる。   In a state where the printing plate 1 is fixed to the plate mounting jig 10, the plate mounting jig 10 is fitted into the plate cylinder 2.

版胴２の嵌合雌部２８を上部に位置させて、版装着治具１０に固定させた状態の印刷用版１を版胴２の外周に被せるようにして版装着治具１０をスライド移動させる。   The plate mounting jig 10 is slid in such a manner that the fitting female portion 28 of the plate cylinder 2 is positioned at the top and the printing plate 1 fixed to the plate mounting jig 10 is placed on the outer periphery of the plate cylinder 2. Let

版装着治具１０の嵌合雄部４２が版胴２の嵌合雌部２８に嵌合すると、版胴２の前面端部が版装着治具１０の本体内輪４の先端側の縁壁４ａに当接する。   When the fitting male part 42 of the plate mounting jig 10 is fitted into the fitting female part 28 of the plate cylinder 2, the front end of the plate cylinder 2 is the edge wall 4 a on the front end side of the main body inner ring 4 of the plate mounting jig 10. Abut.

版装着治具１０の嵌合雄部４２と版胴２の嵌合雌部２８が嵌合されて、版装着治具１０と版胴２が周方向に位置決めされることによって、印刷用版１が版胴２に対して適切な位置となるように周方向に位置決めされる。   When the fitting male part 42 of the plate mounting jig 10 and the fitting female part 28 of the plate cylinder 2 are fitted, and the plate mounting jig 10 and the plate cylinder 2 are positioned in the circumferential direction, the printing plate 1 Is positioned in the circumferential direction so as to be in an appropriate position with respect to the plate cylinder 2.

印刷用版１の前面端部１１１は、本体外輪３の先端側縁壁３ａに当接したままの状態にあり、後面端部１１２は、版胴２の後面端部にまでは到達しておらず、版胴２の中間よりもエンドストッパー２５寄りに位置した状態となる。   The front end 111 of the printing plate 1 remains in contact with the front edge wall 3a of the main body outer ring 3, and the rear end 112 does not reach the rear end of the plate cylinder 2. In other words, the end cylinder 25 is located closer to the end stopper 25 than the middle of the plate cylinder 2.

続いて、印刷用版１の位置決め用切欠部１４が版胴２の位置決め用突部２１に係合されるまで、本体外輪３を版胴２側へ軸方向にスライドさせる。   Subsequently, the main body outer ring 3 is slid in the axial direction toward the plate cylinder 2 until the positioning notch 14 of the printing plate 1 is engaged with the positioning protrusion 21 of the plate cylinder 2.

この時、版胴２の位置決め用突部２１は下部中央に位置し、印刷用版１の位置決め用切欠部１４も下部中央に位置しているので、印刷用版１を後面側へスライドさせるだけで確実に位置決め用切欠部１４を位置決め用突部２１に係合させることができる。   At this time, the positioning projection 21 of the plate cylinder 2 is positioned at the lower center, and the positioning notch 14 of the printing plate 1 is also positioned at the lower center, so that the printing plate 1 is simply slid to the rear side. Thus, the positioning notch 14 can be reliably engaged with the positioning projection 21.

位置決め用切欠部１４が位置決め用突部２１と係合すると、印刷用版１の係合凹部１５と本体外輪３の係合凸部５１との係合を解除して、本体外輪３を逆方向（版胴２から離間する方向）へスライド移動させて、版装着治具１０及び版胴２の係合を解除して版装着治具１０を取り外す。   When the positioning notch 14 is engaged with the positioning projection 21, the engagement between the engagement concave portion 15 of the printing plate 1 and the engagement convex portion 51 of the main body outer ring 3 is released, and the main body outer ring 3 is moved in the reverse direction. The plate mounting jig 10 and the plate cylinder 2 are disengaged by sliding and moving in the direction away from the plate cylinder 2 to remove the plate mounting jig 10.

このように、第１位置決め手段を有する本体外輪３と、第２位置決め手段を有する本体内輪４と、を備え、本体外輪３は、軸方向にスライド動作可能に本体内輪４に外嵌され、本体内輪４は、その外周面で印刷用版１を支持するので、印刷用版１が本体内輪４の外周面に支持された状態で本体外輪３を軸方向にスライド動作させるだけで、版胴２に対する適切な位置を維持したまま印刷用版１を版胴２側に押し出すことができ、印刷用版１をより容易に版胴２に装着させることができる。   Thus, the main body outer ring 3 having the first positioning means and the main body inner ring 4 having the second positioning means are provided, and the main body outer ring 3 is externally fitted to the main body inner ring 4 so as to be slidable in the axial direction. Since the inner ring 4 supports the printing plate 1 on its outer peripheral surface, the plate cylinder 2 can be obtained by simply sliding the main body outer ring 3 in the axial direction while the printing plate 1 is supported on the outer peripheral surface of the main body inner ring 4. Thus, the printing plate 1 can be pushed out toward the plate cylinder 2 while maintaining an appropriate position, and the printing plate 1 can be attached to the plate cylinder 2 more easily.

上述した版装着治具１０は、係合凸部５１を有する版係合部５が本体外輪３と別体で設けられるように説明したが、係合凸部が本体外輪３に設けられた構成であってもよい。   The plate mounting jig 10 described above has been described so that the plate engaging portion 5 having the engaging convex portion 51 is provided separately from the main body outer ring 3, but the configuration in which the engaging convex portion is provided in the main body outer ring 3. It may be.

例えば、図１１に示す版装着治具２０のように、本体外輪３の先端側の縁壁３ａの上端から下端にかけて、連続した凸状に形成され、本体外輪３と一体成形された係合凸部３５が設けられるのであってもよい。   For example, like the plate mounting jig 20 shown in FIG. 11, the engagement protrusion formed in a continuous convex shape from the upper end to the lower end of the edge wall 3 a on the front end side of the main body outer ring 3 and integrally formed with the main body outer ring 3. A portion 35 may be provided.

また、本体内輪４と本体外輪３の軸方向長さ寸法は、先の実施形態では、本体内輪４の軸方向の最大長さ寸法が本体外輪３の軸方向の最大長さ寸法よりも若干長いものを例に説明したが、図１１に示すように、本体内輪４の軸方向の最大長さ寸法が本体外輪３の軸方向の最大長さ寸法の例えば２倍以上の長さ寸法など、本体内輪４の長さ寸法が本体外輪３の長さ寸法よりも十分に長くなるよう設定されるのであってもよい。   The axial length of the main body inner ring 4 and the main body outer ring 3 is slightly longer than the maximum axial length of the main body outer ring 3 in the axial direction. As shown in FIG. 11, as shown in FIG. 11, the main body inner ring 4 has an axial maximum length dimension that is, for example, twice or more of the axial maximum length dimension of the main body outer ring 3 in the main body. The length dimension of the inner ring 4 may be set to be sufficiently longer than the length dimension of the main body outer ring 3.

版装着治具１０，２０は、本体内輪４の長さ寸法が本体外輪３の長さ寸法よりも長く設定されている方が使い易いため好ましいが、本体内輪４の長さ寸法が本体外輪３の長さ寸法よりも短く設定されているのであってもよい。   The plate mounting jigs 10 and 20 are preferable because the length of the main body inner ring 4 is set longer than the length of the main body outer ring 3 because it is easier to use, but the length of the main body inner ring 4 is preferable. It may be set shorter than the length dimension.

上述した位置決め用切欠部１４は、印刷用版１の前面端部１１１の上部側に設けられた係合凹部１５に対して軸方向同一線上の後面端部１１２の下部側に設けられるように説明したが、これに限定されるものではなく、位置決め用切欠部１４の位置は、版装着治具１０，２０によって印刷用版１を装着可能な版胴２を有する印刷機或いは版装着装置の構成などによって決定するとよい。   The positioning notch 14 described above is described as being provided on the lower side of the rear end 112 on the same axis in the axial direction with respect to the engaging recess 15 provided on the upper side of the front end 111 of the printing plate 1. However, the position of the positioning notch 14 is not limited to this, and the position of the positioning notch 14 is a configuration of a printing machine or plate mounting apparatus having a plate cylinder 2 on which the printing plate 1 can be mounted by the plate mounting jigs 10 and 20. It is good to decide by such.

上述したように、版装着治具１０，２０は、円筒状に成形された印刷用版１を版胴２の外周に挿入するためのものであって、印刷用版１と係合して周方向に位置決めする第１位置決め手段と、第１位置決め手段と周方向に位置決めされ、且つ版胴２と係合して周方向に位置決めされる第２位置決め手段と、を備えるので、予め第１の位置決め手段によって印刷用版１を版装着治具１０，２０の適切な位置に係合させ、第２の位置決め手段によって版胴２と版装着治具１０，２０を適切な位置で係合させるだけで、印刷用版１を版胴２の適切な位置に容易且つ確実に装着させることができる。   As described above, the plate mounting jigs 10 and 20 are for inserting the printing plate 1 formed into a cylindrical shape into the outer periphery of the plate cylinder 2, and are engaged with the printing plate 1 to surround the printing plate 1. First positioning means for positioning in the direction, and second positioning means positioned in the circumferential direction with the first positioning means and engaged with the plate cylinder 2 in the circumferential direction. The printing plate 1 is engaged with an appropriate position of the plate mounting jigs 10 and 20 by positioning means, and the plate cylinder 2 and the plate mounting jigs 10 and 20 are only engaged at appropriate positions by the second positioning means. Thus, the printing plate 1 can be easily and reliably attached to an appropriate position of the plate cylinder 2.

版装着治具１０，２０によって印刷用版１を版胴２の適切な位置に確実に装着させることができるので、印刷用版１が版胴２に挿入される際にぶつかるなどして印刷用版１が変形することがない。   Since the printing plate 1 can be reliably mounted at an appropriate position on the plate cylinder 2 by the plate mounting jigs 10 and 20, the printing plate 1 is used for printing by colliding with the printing plate 1 when it is inserted into the plate cylinder 2. The plate 1 is not deformed.

上述した版装着治具１０，２０を用いた版装着方法においても、上述と同様の作用効果を奏する。   Also in the plate mounting method using the plate mounting jigs 10 and 20 described above, the same effects as described above can be obtained.

以上説明した実施形態は、本発明の一例に過ぎず、本発明の作用効果を奏する範囲において具体的構成などを適宜変更設計できることは言うまでもない。   The embodiment described above is merely an example of the present invention, and it is needless to say that the specific configuration and the like can be appropriately changed and designed within the scope of the effects of the present invention.

本発明は、円筒状の印刷用版１を版胴２に装着させるための治具として用いられる。   The present invention is used as a jig for mounting a cylindrical printing plate 1 on a plate cylinder 2.
