とが行なわれている。[Prior art] In a sheet-fed rotary press, the paper printed by the printing unit is transferred from the impression cylinder claw to the paper ejection chain claw, and is then released from the claw at the end of the conveyance and falls. It is loaded onto the loading platform. In this type of conveyance device, the paper is only held at the leading end by the claws, so the tail of the paper flaps around) or when the paper is released from the claws, inertia remains, causing the stacking. Sometimes the edges of the paper are not aligned, so to prevent this, a pair of suction wheels are installed in parallel in the width direction of the paper near the end of the conveyance. By bringing the paper into contact with the paper, the speed of the paper is slowed down.

断しなければならないことがあった。However, this suction wheel is good if the printing machine is single-sided printing, but
When this is installed on a double-sided printing press, the printed surface will come into sliding contact with the suction wheel, so if the width of the non-printing area is narrower than the width of the suction wheel, the printed surface will become dirty or damaged and the quality of the printed matter will deteriorate. It was often horizontal paper. In such cases, conventional practice has been to switch the air in the suction wheel from suction to blow-up, but this reduces the paper deceleration function and greatly impairs paper alignment during paper ejection. Not only is it unavoidable to slow down the operating speed of the machine, which significantly reduces productivity, but it also makes it impossible to maintain proper air control for everything other than the suction wheel, and work is often interrupted due to poor paper ejection. There was something I had to do.

By using double-sided printing paper whose non-printing part facing the suction wheel surface is narrower than the width of the suction wheel, the printing part comes into close contact with the circumferential surface of the suction wheel, which enables high-speed operation and prevents paper from getting dirty. To provide a paper ejecting device for a double-sided sheet-fed rotary printing press that can improve productivity and reduce the amount of waste paper without causing scratches or scratches. Hereinafter, a practical example of the present invention will be explained in detail based on the drawings.

上に積載される。The operation of the paper ejecting device configured as above will be explained. The paper 8 printed by the printing unit is transferred from the claw of the impression cylinder to the claw 7 of the paper ejection chain 6, and the paper 8 is transferred from the claw of the impression cylinder to the claw 7 of the paper ejection chain 6.
It is conveyed by running in the direction. After the gripping end of the paper 8 being conveyed passes above the suction part fi13, the non-holding part of the paper 8 comes into sliding contact with the suction wheel 24, and the suction hole 2 of the suction wheel 24 is opened.
From G, there is a hose 31 and an air passage 29.25 depending on the intake source.
Since the outside air is sucked in through the suction wheel 24, the paper 8 is completely attracted to the surface of the suction wheel 24, and since the circumferential speed of the suction wheel 24 is much slower than the transport speed of the paper 8, the paper 8 separates from the wheel 24. At the same time, it is released from the grip of claw 1 and falls. This paper 8 is conveyed by the claw 1 and decelerated by the suction wheel 24, and falls diagonally forward while being given appropriate running inertia.
The front end comes into contact with the front support 11 and is aligned in the vertical direction. In addition, the paper private board 10 is aligned in the width direction by the side board 12.

とができる。As is clear from the above description, according to the present invention, in the sheet discharge device of a double-sided printing sheet-fed rotary printing machine, a ring made of an elastic phase is provided, and the width of the non-printing area in double-sided printing is When the width of the suction wheel is smaller than the width of the suction wheel, such a printed matter can be produced by fitting this ring into an annular groove provided on the circumferential surface of the suction wheel so that a part of the ring protrudes from the circumferential surface of the suction wheel. In this case, it is possible to separate the printing part of the printed material from the circumferential surface of the suction wheel without switching the suction wheel to blow up, thereby preventing stains and scratches on the printed material, improving the quality of the printed material and improving the papermaking process. In addition to reducing the amount of paper generated, by being able to work in the suction state, the deceleration function of the suction wheel and paper alignment function during paper ejection can be ensured without the need for low-speed operation, making it possible to increase the speed. This significantly improves productivity. In the case of single-sided printed matter or double-sided printed matter with a large non-printing area, simply remove the ring, turn it over, and store it in the annular groove. The deceleration function can be further improved, and the labor required when switching between printed materials can be reduced.
