本発明は、印刷機の紙送り胴の吸着装置に関するもので
ある。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a suction device for a paper feed cylinder of a printing press.
一般に、両面刷り印刷機では印刷機の所定の位置で紙を
裏返す必要があるので、紙送り胴が設けられ、この紙送
り胴には、胴の軸方向に沿って多数の咥え爪と、紙を胴
に吸着させるサクションヘッドとが設けられている。Generally, in a double-sided printing press, it is necessary to turn the paper over at a predetermined position on the printing press, so a paper feed cylinder is provided, and this paper feed cylinder has a large number of gripping claws along the axial direction of the cylinder. A suction head is provided to attract the paper to the cylinder.
これらのサクションヘッドは紙の幅方向に一直線状に並
設されているので、紙の幅よりも外にくるサクシ5ンヘ
ノドは、各サクションヘッドに取付けられたパルプを閉
じてエアー漏れを防いでいる(例えば、特公昭55−2
6982号公報参照)。These suction heads are arranged in a straight line in the width direction of the paper, so the suction heads that are outside the width of the paper close the pulp attached to each suction head and prevent air leakage. (For example, Tokuko Sho 55-2
(See Publication No. 6982).

いる。This rotary valve pipe 11 is provided at the installation position of the air pipe 7 in the conventional example described above, and is fitted inside a fixed pipe 12 having an external port 12a that communicates with each communication hole 10, and this fixed pipe 12. It also includes a valve pipe 13 having an inner opening 13a located at a position corresponding to the paper size. As shown in the developed view of FIG. 4, the positions of the inner openings 13a are bored in such a way that the number of holes increases sequentially according to the paper size, so by rotating the valve pipe 13, it is possible to correspond to the paper size. It looks like this. A ring 14 is interposed between the fixed pipe 12 and the valve pipe 13 to provide a seal.

できないようにしている。In addition, in FIG. 6, a shaft-shaped stopper 16 is inserted and fixed into a valve pipe 13 that protrudes outward from a frame 15 supported by a drum shaft 2 at the end of the paper feed cylinder 1 shown in the conventional example. A concentric annular cam 17 is rotatably inserted into the hollow portion of the annular plug body 16. A circumferential groove 18 is recessed in the outer periphery of the stopper 16, and a stopper pin 20 attached to a bracket 19 extending from the frame 15 is fitted into the circumferential groove 18. The body 16 is prevented from sliding in the axial direction.

管13は回動することになる。Further, an axial groove 21 and a spiral cam groove 22 are recessed in the outer circumference of the cam 17, and the groove 21 has a cam pin 23 attached to the bracket 19, and the spiral cam groove 22 has a plug. Cam pins 24 attached to the body 16 are fitted respectively. Therefore, if the cam 17 is moved in the direction of the cylinder axis, the valve pipe 13 will be rotated by these pins 20, 23, and 24.

復動ロッド27に連結されている。A doughnut-shaped connecting plate 25 is fixed to the outer end of the cam 17, and the connecting plate 25 is sandwiched between a pair of rollers 26 and connected to a reciprocating rod 27.
したがって、紙送り胴1が回転しても往復動ロッド27
の支障はない。Therefore, even if the paper feed cylinder 1 rotates, the reciprocating rod 27
There is no problem.

2の外聞口12aに合致する。Next, to describe the operation of this embodiment, in order to open and close the suction head 5 according to the paper size while the printing press is at rest, for example, as shown in FIG. However, when the width of the paper increases and it becomes necessary to open it to cross section B, all that is required is to rotate the valve pipe 13. When the operator pushes and pulls the reciprocating rod 27, the connecting plate 25 moves in the axial direction of the cylinder. The cam 17 is reciprocated in the same direction. As a result, the cam bin 24 is guided by the spiral cam groove 22 and rotates, so the plug body 16 rotates and the valve pipe 1
3 rotates, and the inner opening 13a of a predetermined paper size is inserted into the fixed tube 1.
This corresponds to the outer listening port 12a of No.2.
そこで、エアー用キリ孔28を介して図示しないバキュ
ームポンプにより吸引すれば、所定の紙サイズのサクシ
ョンヘッド5のみが吸着作用を行う。Therefore, if suction is performed by a vacuum pump (not shown) through the air perforation 28, only the suction head 5 of a predetermined paper size will perform the suction action.
