この発明は輪転グラビア印刷機用の折曲機の改良に関す
る。DETAILED DESCRIPTION OF THE INVENTION [Technical field to which the invention relates] This invention relates to an improvement in a folding machine for a rotogravure printing press.
従来公知の輪転グラビア印刷機用の折曲機は、挾持円筒

うに配置された逆回転の把持円筒を有し、その挾持円筒

後「解放位置」と呼ぶ）で、挟持円筒内に完全に引込ん

持円筒に対して半径方向の往復運動をするようになった
刃先すなわち「押し刃」を備えている。A conventional folding machine for a rotogravure printing press has a gripping cylinder and a counter-rotating gripping cylinder arranged parallel to the gripping cylinder so as to be substantially in contact with each other along the generatrix, and the outer periphery of the gripping cylinder is An odd number (usually five) of movable clamping units are arranged along rows corresponding to the same number of generating lines of the cylinder. The clamping cylinder is also in the next position between each clamping unit in the direction of rotation of the cylinders, in the region of the contact generatrix of the two cylinders (hereinafter referred to as the "release position"), in a fully retracted position within the clamping cylinder. It is equipped with a cutting edge, that is, a "pushing blade", which makes a reciprocating motion in the radial direction with respect to the clamping cylinder between a position that partially protrudes from the clamping cylinder.
把持円筒の外周にはその母線に沿って偶数個（普通４個

通過するたびにこれに応じて把持ユニットが１個ずつそ
こを通過し、押し刃が半径方向外方に移動中そのユニッ
トの開いた把持部材の間に進入するように挾持円筒と連
動されている。An even number (usually 4) of movable gripping units are arranged on the outer periphery of the gripping cylinder along its generatrix, and each time the push blade passes through the release position, one gripping unit passes therethrough. , is interlocked with the gripping cylinder such that the pusher blade enters between the open gripping members of the unit during radial outward movement.
以上の説明から、従来公知の折曲機では挾持円筒の外周
の挾持ユニットの数が把持円筒の外周の把持ユニットの
数と常に異なることが判る。From the above description, it can be seen that in conventional folding machines, the number of clamping units on the outer periphery of the clamping cylinder is always different from the number of gripping units on the outer periphery of the gripping cylinder.
この差は累積式生産例えば「２枚重ね式」生産を行い得
るようにするために必要で、実際この場合は、各挾持ユ
ニットがまず１枚目の紙を受取シ、次に回転して来たと
き２枚目の紙を受取ることができるように、挟持円筒の
外周に奇数個の挟持ユニットを等間隔で配置する必要が
あるが、一方把持円筒の外周に偶数個の把持ユニットが
配置されているだめ累積式生産が極めて容易になる。す
なわち把持円筒から１つおきに把持ユニットを省略する
ことにより、１枚目の紙が解放位置を通過するときに抜
き取られるのを簡単に防ぐことができる。同時に挟持円
筒には紙が解放位置を通過するとき抜取られなければ紙
固定用挟持部部材の開くのを防ぐ制御装置が取付けられ
ている。This difference is necessary in order to be able to perform cumulative production, e.g. "double-sheet" production, in which case each clamping unit first receives the first sheet and then rotates. It is necessary to arrange an odd number of gripping units at equal intervals around the outer periphery of the gripping cylinder so that the second sheet can be received when the second sheet is picked up. Accumulative production becomes extremely easy. That is, by omitting every other gripping unit from the gripping cylinder, it is possible to easily prevent the first sheet of paper from being pulled out when passing through the release position. At the same time, the clamping cylinder is fitted with a control device which prevents the paper fixing clamp member from opening unless the paper is removed when it passes through the release position.
上述の動作様式には、第１に挾持ユニットと把持ユニッ
トの数の違いのだめ、把持ユニット数ヲｎとすると僅か
ｎ回転ごとに挟持ユニットが同じ把持ユニットと共働し
て、挾持円筒と把持円筒の構造とその運動の調節に著し
い問題を生ずるという顕著な欠点がある。The above-mentioned mode of operation is primarily due to the difference in the number of clamping units and gripping units; if the number of gripping units is n, a clamping unit cooperates with the same gripping unit every n rotations, and the clamping cylinder and the gripping cylinder are There are significant disadvantages in the structure of the system and the regulation of its movements that pose significant problems.
第２に、公知の折曲機を累積式生産に適用するように改
変するには比較的時間がかかり、押し刃の運動が無制御
のままになる。この押し刃は実際に解放位置を通過する
とき常に下方に動いて、その位置に把持ユニットがない
ため紙が抜取られないときでも、その紙が同様に関連す
る押し刃に係合して、場合によっては対応する挟持部材
に対して変位し、次の紙と完全に重ならなくなることが
ある。Second, modifying known folding machines for cumulative production applications is relatively time consuming and leaves the motion of the pusher blades uncontrolled. This pushing blade actually moves downwards whenever it passes through the release position, so that even when the paper is not pulled out because there is no gripping unit in that position, the paper engages the associated pushing blade as well, and if In some cases, the paper may be displaced relative to the corresponding holding member and may not completely overlap the next paper.
この発明の目的は上述の欠点のない輪転グラビア印刷機
用折曲機を提供することである。The object of the invention is to provide a folding machine for a rotogravure printing press which does not have the above-mentioned disadvantages.

に来る。During production of each manuscript 17 of the non-cumulative type, the roller 34 engages with the recessed part 36 of the fixed cam 35, and the roller 43 engages with the cam 44 again.
The receiver is inserted into each clamping unit 24 of the clamping cylinder 20 at the loading position where it is necessary to engage the recessed part 45 of the clamping cylinder 20. In other words, when a manuscript 17 is fed to the acceleration unit 18 at the associated clamping unit 240, the curved clamping arm 54 of that clamping unit separates from the abutment surface 56, causing the manuscript 1
The curved edge 70 enters and can then contact 56. Further rotation of the clamping cylinder 2o causes the roller 34 to disengage from the recess 36, so that the clamping arm 54 closes over the old edge of the manuscript 170 and fixes it to the cylinder 2°, and the roller 43 then moves the cam 44 It passes through the recessed part 45. This roller 4
During the movement of 3, the flat clamping arm 55 opens, rises from beneath the manuscript 17 secured by the corresponding curved clamping arm 54, and closes again on the leading edge of the manuscript 17. The manuscript 17 fixed in this way is placed between two consecutive clamping units along the outer periphery of the clamping cylinder 20, and the center part is located between the two clamping units 1- by the pushing blade of the folding unit 25. Comes on top of 74.

する。Said manuscript 17 is released from the clamping cylinder 20 when the associated pushing blade 74 passes through the generatrix where the cylinders 2o, 21 are substantially in contact. At the same time that the push blade 74 reaches this release position, the corresponding gripping unit 26 supported by the gripping cylinder 21 and previously opened by actuating means (not shown) also arrives.

4 to protrude the pushing blade 74,
For this purpose, the center of the manuscript 17 placed there is lifted from the cylinder 20 and pushed between the open grips 26. When the gripping member 26 is closed again, it holds the manuscript 17 by folding it in two, removes it from the clamping cylinder 20, and transports it to the point of use. The manuscript 17 can be completely separated from the clamping cylinder 20 only when the pushing blade 74 protrudes outward.
The roller 34 of the clamping unit 24 located in front of the rotation direction of 0
engages with the recessed part 37 of the fixed cam 35 to open the associated curved clamping arm 54, and at the same time, the roller 43 of the clamping unit 24 engages with the recessed part 46 of the cam 44 to open the associated curved clamping arm 54.
5 is opened, and the manuscript 1 is already held by the gripping member 26.
7 is finally released.

１の印刷物に関する１枚目の写本１７と第２の印刷物に
関する２枚目の写本から成る堆積体の形で移送される。In cumulative production, for example, when stacking two printed sheets,
The manuscript 17 is not transferred from the clamping cylinder 20 to the gripping cylinder 21 each time as in the case of the non-cumulative type, but the first manuscript 17 relating to the first printed matter and the second copy relating to the second printed matter are stacked in a predetermined order. It was transported in the form of a deposit consisting of manuscripts.
この２枚累積動作は支軸２２従って挾持円筒２０と異る
（通常それより低い）所定の回転速度で支軸５３．７１
によシ回転されるカム４８．６６の角度を適当に調整す
ることにより可能になる。This two-sheet cumulative operation is carried out by the support shaft 53.
This is made possible by appropriately adjusting the angle of the cams 48 and 66 that are rotated.
すなわち第８図に示すように、カム６６の突出部６７を

合のだめ押上げられたままでいるようにする。That is, as shown in FIG. 8, the protruding part 67 of the cam 66 is overlapped with the recessed part 65 of the cam 64, so that only one of the two rollers 63 that sequentially moves on the cam 64 engages with the recessed part 65. , the other remains pushed up by one protrusion 670. Similarly, as shown in FIG. 5, the protrusion 49 of the cam 48 interferes with one of the two recessed parts 46 of the cam 44, so that only one of the two rollers 43 that sequentially move on the cam 44 is It engages the associated recess 46 so that the other remains pushed up due to engagement with one of the protrusions 49 of the associated roller 47.
以上のようにすると、カム４８は挾持円筒２０の回転方

の１つによシカムロ４の凹欠部６５への係合を阻止され
ている間はすべてローラ４３がカム４４の凹欠部４６に
係合するのを阻止することが判る。With the above arrangement, the cam 48 rotates in the direction of rotation of the clamping cylinder 20 so that the roller 63 that is driven by the protrusion 67 of the cam 66
It can be seen that while one of the rollers 43 is prevented from engaging the recess 65 of the cam 4, the roller 43 is prevented from engaging the recess 46 of the cam 44.

になっている。For example, in cumulative production in which two sheets are stacked, the gripping unit 2
The manuscripts 17 moved by the clamping cylinder 20 towards the release position where they are picked up by the cylinder 6 are alternately of a first and second type, corresponding respectively to the first and second printed products of the cylinder 2.3. When the first manuscript 17 of the first type comes to the release position with its center just in front of the gripping unit 26, one of the protrusions 670 of the rotary cam 66 driven by the support shaft 71 moves from the cam 64. It coincides with the concave notch 65 to prevent the roller 63 from descending, thereby preventing the pushing blade 74 from protruding. Similarly, the protrusion 49 of the cam 48 coincides with the recess 46 and cooperates with the roller 47 to prevent the roller 43 from engaging the recess 46 of the cam 44, but the roller 34 does not fit properly. It is adapted to engage with a recessed notch 37 of the fixed cam 35.

筒２０に保持されたままとなる。As a result, when the center of the first type manuscript 17 comes to the release position, the gripping member 26 opens and closes correctly, but the corresponding push blade 74 does not operate, so the adjacent manuscript 17 is not extracted. The curved clamping arm 54 still opens and closes correctly, but the flat clamping arm 55 remains closed, so the manuscript 17 remains held in the clamping cylinder 20.

In this position, the manuscript 17 is held in the clamping cylinder 20 by the flat clamping arm 55, but the curved clamping arm 54 "opens to display the second manuscript 17".
The clamping unit 24 closes after receiving an odd number of copies (of the second type), and the flat clamping arms 55 open and close again over the stack formed by the two overlapping manuscripts 17.
