た印刷機のローラ位置調整装置に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a roller position adjustment device for a printing press, and more specifically, for example, in a printing press, an ink forming roller can be brought into contact with and separated from a plate cylinder, and the roller position adjustment device When positioning, the position of the ink form roller is automatically adjusted following the eccentric movement of the plate cylinder, so that the ink form roller is always kept in good pressure contact with the plate cylinder for printing. No unevenness in images or lines,
Therefore, the present invention relates to a roller position adjustment device for a printing press that makes it possible to obtain printed matter with excellent quality and accuracy.
種々の印刷機械の中、輪転印刷機が広汎に普及している
。前記輪転印刷機は、基本的には、版板を巻き付けた版
胴と前記版胴にインキを供給する着肉装置と前記版胴に
接して印刷を行う圧胴とを含む。この場合、着肉装置で
は一般的に以下のように構成されている。Among various printing machines, rotary printing presses are widely used. The rotary printing press basically includes a plate cylinder around which a printing plate is wound, an inking device that supplies ink to the plate cylinder, and an impression cylinder that performs printing in contact with the plate cylinder. In this case, the inking device is generally configured as follows.
すなわち、インキ溝からインキ出しローラにインキを供
給し、このインキをインキ移しローラに転移させた後、
これを複数のインキ練りローラ群に順次移送する。イン
キ練りローラにより好適に練られたインキをさらにイン
キ着けローラに供給し、最終的に、前記インキ着けロー
ラが圧接する版胴に巻き付けられた版仮に前記インキを
転移し印刷作用に供している。That is, after supplying ink from the ink groove to the ink dispenser roller and transferring this ink to the ink transfer roller,
This is sequentially transferred to a plurality of ink mixing roller groups. The ink suitably kneaded by the ink mixing roller is further supplied to an ink forming roller, and finally, the ink is transferred to the plate wrapped around the plate cylinder, which is pressed against the ink forming roller, and is subjected to a printing action.
ところで、前記着肉装置では、印刷時に版胴に圧接して
いるインキ着げローラを印刷を行わない際には前記版胴
から離間させる必要がある。By the way, in the ink applicator, it is necessary to separate the ink applicator roller, which is in pressure contact with the plate cylinder during printing, from the plate cylinder when printing is not performed.
例えば、版胴にインキ着けローラを常時圧接していると
、その圧接部位にインキの固着層が形成され、再び印刷
を開始する際に前記固着層に印刷紙が付着して印刷紙自
体が破損したり、あるいは、印刷不良となって品質精度
の低下を惹起してしまう。For example, if an ink applicator roller is constantly pressed against the plate cylinder, a sticky layer of ink will be formed at the pressure contact area, and when printing starts again, the printing paper will stick to the sticky layer and the printing paper itself will be damaged. Otherwise, printing defects may occur, resulting in a decrease in quality accuracy.
そこで、インキ着けローラを版胴に対して圧接・離間さ
せるため、従来からローラ移動装置が使用されている。Therefore, a roller moving device has conventionally been used to press the ink form roller against and separate it from the plate cylinder.
この従来技術に係るローラ移動装置ではインキ着けロー
ラの両端を夫々アーム部材に回転自在に支承すると共に

ンキ練りローラを中心にしてt3動自在に構成されてい

エータを設けたリンク機構が係合している。In this conventional roller moving device, both ends of the ink form roller are rotatably supported by arm members, and the arm members are configured to be movable t3 around an ink mixing roller that is in pressure contact with the ink form roller. ing. Furthermore, a link mechanism provided with an actuator such as an air cylinder is engaged with the arm member.
このような構成において、アクチュエータの作用下に前
記リンク機構を介してアーム部材がインキ練りローラを
中心にして揺動し、結果的に、インキ着けローラは版胴
に対して圧接並びに離間変位して所定の位置に位置決め
される。In such a configuration, the arm member swings around the inking roller through the link mechanism under the action of the actuator, and as a result, the inking roller is pressed into contact with the plate cylinder and displaced away from it. positioned at a predetermined position.
一方、前記版胴と圧胴とはその軸線方向に均一な圧力で
接していなければならない。例えば、版胴と圧胴との接
触面における圧力が不均一であれば、前記版胴と圧胴と
の間を通過する印刷紙には画線の潰れやむら等が惹起し
、印刷不良の大きな要因となってしまう。そこで、版胴
の一端側、あるいは、両端側を偏心させて圧胴に対し好
適な圧接状態を確保するよう調整作業を行っている。On the other hand, the plate cylinder and the impression cylinder must be in contact with each other with uniform pressure in their axial directions. For example, if the pressure on the contact surface between the plate cylinder and the impression cylinder is uneven, the printing paper passing between the plate cylinder and the impression cylinder will have crushed or uneven print lines, resulting in poor printing. It becomes a big factor. Therefore, adjustments are made to make one end or both ends of the plate cylinder eccentric to ensure a suitable state of pressure contact with the impression cylinder.
然しなから、前記のようにして版胴を偏心させると、こ
の版胴とインキ着けローラの圧接状態が変化してしまう
。例えば、版胴の一端側の中心が偏心すれば、前記版胴
とインキ着けローラとの接触圧が両端部で夫々異なり、
結局、品質精度の低い印刷物となってしまう。従って、
版胴の位置調整を行って後、さらに、インキ着けローラ
の中心位置調整作業を行わなければならない。すなわち

クの長さを調整してインキ着けローラの一端側を偏心さ
せると共に、その都度試し刷りを行い、最終的に、良好
な印刷物が得られた位置において前記ターンパンクルを
固定することにより前記調整作業を行っている。However, if the plate cylinder is made eccentric as described above, the state of pressure contact between the plate cylinder and the ink forming roller changes. For example, if the center of one end of the plate cylinder is eccentric, the contact pressure between the plate cylinder and the ink forming roller will be different at both ends.
In the end, the resulting printed matter has low quality accuracy. Therefore,
After adjusting the position of the plate cylinder, it is necessary to further adjust the center position of the inking roller. In other words, by adjusting the length of the links that make up the link mechanism via turnbuckles, etc., one end of the inking roller was made eccentric, and trial printing was performed each time, and in the end, good printed matter was obtained. The adjustment work is carried out by fixing the turnspuncle in position.
このように、前記の従来技術では、版胴を位置調整する
際にインキ着けローラの偏心作業を行っており、しかも

のであるために、実際上、相当なμi練者に依存せざる
を得す、さらに、このような経験者ですらその調整作業
に相当な時間を要してしまう。このため、効率的な印刷
作業を行うことが不可能となる不都合が露呈する。In this way, in the above-mentioned conventional technology, when adjusting the position of the plate cylinder, the ink forming roller is eccentrically operated, and as mentioned above, the adjustment operation is extremely complicated. In practice, it is necessary to rely on a person with considerable μi expertise, and furthermore, even such an experienced person takes a considerable amount of time to perform the adjustment work. For this reason, a disadvantage arises in that it is impossible to perform efficient printing work.

線上に位置する。Here, the arm member 40 has one end engaged with the link pin 76, and a hole 44 provided at the other end loosely fits the bearing housing 38 of the ink mixing roller 16. Therefore, the arm member 40 swings around the link pin 76, and the center of the hole 44 is eccentric with respect to the center of the bearing housing 38. As a result, the ink form roller 14 is eccentric in the direction of arrow F, and the distance between the ink form roller 14 and the roller 58 is always maintained constant, and the distance between the center of the ink form roller 14, the center of the roller 58, and the plate cylinder 12 is maintained constant. It is located on the same line as the center.

が偏心することはない。In this way, by simply adjusting the position of the plate cylinder 12, the ink applicator roller 14 in pressure contact with the ink applicator roller 14 follows the eccentric movement of the plate cylinder 12, and the ink applicator roller 14 and the plate cylinder 12 are brought into pressure contact with each other. It becomes possible to ensure a uniform and good condition in the axial direction. In this case, since the stopper member 62 that engages with the end of the swing lever 56 is pressed by the disc spring 72, the impact that is likely to be caused to the arm member 40 when adjusting the position of the plate cylinder 12 is absorbed by the arm member 40. It can be relaxed through the elastic force of the spring 72. Furthermore, since the coil spring 74 is engaged with the groove 60b of the swing lever 56, for example, the elastic force of the disc spring 72 that acts on the swing lever 56 when separating the ink form roller 14 from the plate cylinder 12 This makes it possible to suitably hold the swing lever 56 against this. Note that the bearing housing 38 is loosely fitted into the hole 44 of the arm member 40;

つ効率的に行うことが可能となる。As described above, according to the present invention, the roller and the plate cylinder are brought into pressure contact and separated from each other via the link mechanism, and when positioning the plate cylinder, the ink form roller follows the eccentricity of the plate cylinder. Equipped with a roller position adjustment mechanism that automatically eccentricizes the roller. Therefore, it is not necessary to adjust the ink forming roller or the like that presses against the plate cylinder by simply adjusting the position of the plate cylinder. In the end, compared to the conventional method of manually aligning the ink form roller while making test prints, the work of adjusting the position of the plate cylinder and rollers is extremely simple and efficient. becomes.
