本発明は９枚葉印刷機における印刷紙排紙機構に関する
ものであるが、特に搬送中の印刷紙を吸着させる吸引車
を配設した印刷紙排紙機構に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a printed paper ejecting mechanism in a nine-sheet printing press, and particularly relates to a printed paper ejecting mechanism equipped with a suction wheel that attracts printed paper during conveyance. be.

吸引車を取付けて、＊途中の印刷紙を吸着させグリッパ
−が紙放しを行ったとき印刷紙のスピードを減速させて
紙積台上に積載している。In sheet-fed printing machines, the printed paper is transported to a predetermined position and stacked by several grippers connected to a chain. For this reason, a suction wheel equipped with an air suction device and constantly rotating was installed to absorb the printed paper in the middle, and when the gripper released the paper, the printed paper was removed. The speed is reduced and the paper is loaded onto the paper stacking platform.

した場合と同様に良好な紙揃えを行うことができない。When a separate motor or the shaft of the printing press is used to drive such a suction wheel, various problems arise. In other words, (1) If a separate motor is used to drive the suction wheel and the rotation of the suction wheel is kept constant regardless of the rotational axis of the printing press, If the rotation of the suction wheel is set so that the paper is properly aligned at the loading position, if the printing machine is rotated at maximum speed, the speed of the printing paper being conveyed cannot be reduced enough and the speed of the printing paper being conveyed cannot be reduced enough and Also, the leading edge of the paper may be damaged due to the strong contact. If you set the rotation of the suction wheel so that the printing paper is properly aligned at the loading position when the printing press is at its maximum speed, if the printing press is rotated at a low speed, If the speed of the printing paper is reduced too much, the leading edge of the printing paper will not reach the paper stop, resulting in uneven printing paper. (2) Next, when the suction wheel is driven through the base shaft of the printing press, and the suction wheel is rotated once by the rotation base of the printing press, ■ When the rotation of the printing press becomes faster, the gripper transports the suction wheel. As the speed of the printing paper being transported increases, the rotation of the suction wheel also increases accordingly. Conversely, when the rotation of the printing press slows down, the speed of the printing paper being conveyed by the gripper also slows down. , the rotation of the suction wheel also becomes slower. As a result, paper alignment cannot be performed as well as in the case where the single motor is used.

刷機における印刷紙排紙機構を提供するものである。The present invention has been improved in order to solve the above-mentioned problems, and the printing paper ejection mechanism is equipped with a suction wheel that constantly sucks the printed paper from the suction hole, and the rotation speed of the printing press is increased. In some cases, the rotation speed of the suction wheel is slowed down, and on the other hand, when the rotation speed of the printing press is slowed down, the rotation speed of the suction wheel is increased.] The wheel is driven independently. To provide a printed paper discharge mechanism in a printing press, which aims to always perform good alignment of printed paper no matter whether the rotation of the printing press is fast or slow, by interlocking with the rotation axis of the printing press. It is something.

This machine consists of a paper feeding mechanism (paper feeding mechanism), a printing mechanism (B), and a paper ejection mechanism (0). This printing mechanism (B) is already a printing mechanism based on a conventionally known technology. The part (0) in this figure is the paper ejecting mechanism of the present invention. In other words, the paper feed mechanism (
The printing paper (ate") conveyed from A) is transferred to the chain (B
), the gripper (6) attached to the paper stacking table (e
) and at the same time transport the printing paper (&2) to the suction wheel (W).
This is a mechanism that sequentially loads printing paper (a2) onto a paper stacking table (θ) by suctioning it to the paper stacking table (θ). 〇Figure 2 shows one of the conventionally known suction wheels (@) used in the mechanism of the present invention. and 1
is the suction wheel. As is clear from this figure, the suction wheel 1 is provided with several suction holes 3, and a suction pipe 4 is connected to an air hose 5 so that suction can be drawn through the suction holes 3 at all times. That is, by driving the suction axle 2 and rotating the suction wheel at a constant speed, air (not shown) is constantly sucked from the suction pipe 4', and the air is drawn from the suction hole 3 that matches the suction pipe 4'. It can be sucked. 6 is a suction wheel holder. Next (a) by diagram.
吸引車の取付方と作用について説明する。まず吸引車フ
レーム７、吸引車移動ガイド８．チェーンガイドレール
１０を介して吸引車１を配設する。この吸引車１を用い

当１７の方向に搬送されて吸引車１のＰ点にて印刷紙１
５を吸着し９紙積台１８に順次積載することができる。We will explain how to install the suction wheel and how it works. First, the suction wheel frame 7, the suction wheel movement guide 8. A suction wheel 1 is disposed via a chain guide rail 10. By using this suction wheel 1, several grippers 13 connected to the conveyance chain 9 grip the gripping portion 14 of the printing paper 15 and are conveyed in the direction of the paper abutment 17 of the suction wheel 1. Dot printing paper 1
5 can be suctioned and stacked sequentially on the 9 paper stacking table 18.
しかし、この場合、印刷紙１５の搬送速度と吸引車３の
回転速度が異なるために、グリッパ−１３から印刷紙１
５を放す際に、印刷紙１５の搬送速度よりも吸引車１の
外周速度を減速させて紙揃えをする必要がある。However, in this case, since the conveying speed of the printing paper 15 and the rotational speed of the suction wheel 3 are different, the printing paper
5, it is necessary to reduce the outer peripheral speed of the suction wheel 1 than the conveyance speed of the printing paper 15 to align the paper.
そこで、この吸引車１の吸引車軸２を単独モーターにて
駆動させ、印刷機の回転が連＜ナレば吸引車１の周速回
転が遅くなるようにする７と共に、印刷機の回転が遅く
なれば吸引車の周速回転が速く （搬送中の印刷紙１５
のスピードより減速している状態）になるようにするた
めに。Therefore, the suction axle 2 of the suction wheel 1 is driven by a separate motor, and if the rotation of the printing press becomes continuous, the peripheral speed of the suction wheel 1 is slowed down. If the peripheral speed of the suction wheel is fast (printing paper 15 being transported)
in order to achieve a state where the speed is slower than the speed of
スプロケット１２の駆動軸１１と印刷機の回転基軸とを
連動させたのが１本発明機構の要部である。An important part of the mechanism of the present invention is that the drive shaft 11 of the sprocket 12 and the rotation axis of the printing press are interlocked.
すなわち、印刷機の回転が速い場合には、吸引車１の周
速回転は遅くなって、グリッパ−１３が印刷紙１５を放
した場合に搬送中の印刷紙１５に多くのブレーキをかけ
て印刷紙１５の先端が紙当１７に強く当るのを防止する
ことができる。また。That is, when the rotation of the printing press is fast, the circumferential speed rotation of the suction wheel 1 becomes slow, and when the gripper 13 releases the printing paper 15, many brakes are applied to the printing paper 15 being conveyed to prevent printing. It is possible to prevent the leading edge of the paper 15 from strongly hitting the paper abutment 17. Also.
印刷機の回転が遅い場合には、吸引車１の回転は速く
（その場合搬送中の印刷紙１５のスピードよりは減速し
ている）なって、グリッパ−１３が印刷紙１５を放した
場合に搬送中の印刷紙１５に少しブレーキをかけて、印
刷紙１５の先端が紙当１７までとどくようにする。そう
すれば、印刷機の回転の速い遅いにかかわらず、常に紙
当１７に対しては印刷紙１５はソフトになって常時良好
な紙揃えを行うことができる。When the printing press rotates slowly, the suction wheel 1 rotates quickly.
(In that case, the speed is slower than the speed of the printing paper 15 being conveyed.) Therefore, when the gripper 13 releases the printing paper 15, it applies a slight brake to the printing paper 15 being conveyed. Make sure the tip reaches the paper stopper 17. In this way, regardless of whether the rotation speed of the printing press is fast or slow, the printing paper 15 will always be soft against the paper rest 17, so that good paper alignment can always be performed.

たものである。FIG. 3 is a driving block diagram of a motor for a suction wheel for performing the driving action as described above. As is clear from this block diagram, the rotational speed of the main motor of the printing press and the rotational speed of the suction wheel motor can be freely adjusted by using a conventionally known proportional signal output device.
