くわえ替えて搬送するように構成されている。In the sheet-fed rotary printing press, the paper printed by the printing cylinder of the printing unit is conveyed by the paper ejection chain, and is ejected and stacked on the paper stack plate of the paper ejection device. In the paper delivery section from the printing unit to the paper ejection chain, a sprocket with the paper ejection chain attached coaxially with the paper take-up cylinder is provided in contact with the impression cylinder of the printing unit. When gripping the paper from the gripper device (hereinafter referred to as the nail) to the grip of the paper ejection chain, hold the part of the paper other than the gripping edge between the peripheral surface of the rotating impression cylinder and the peripheral surface of the paper take-up cylinder. It is configured to be changed and carried while being carried. Also, in the case of a multi-color printing machine, a transfer cylinder is provided between the impression cylinders of adjacent printing units of different colors, and when changing the paper from the impression cylinder's claw to the transfer cylinder's claw, the gripper edge of the paper The other part is configured to be gripped between the peripheral surface of the rotating impression cylinder and the peripheral surface of the transfer cylinder while being gripped and transported.

されるように構成されている。In the present device, the peripheral surface of the transfer cylinder 6 has a cylinder peripheral space portion other than a portion corresponding to the claw holder 9 which is a gripping end of the paper 22.
It is completely open to the outside of the body without being covered with anything, and an air blowing device for blowing air to the paper 22 conveyed along the circumference of the body is provided in the center of the body. That is,
A valve case 23, which is formed in an annular shape concentric with the transfer cylinder 6, is bolted to one frame 11, and the disk 8 of the transfer cylinder 6 is brought into sliding contact with the valve case 23 and the end surfaces thereof. An annular valve ring 24 that rotates with the transfer cylinder 6
Is fixed. Further, between the left and right discs 8, a plurality of nozzle tubes 26 having a large number of nozzles 25 directed toward the outside of the body are provided.
Is supported on both sides of the pawl holder 9 by engaging one end with the hole 24a of the nozzle ring 24, while the hole 23a provided on the outer peripheral portion of the valve case 23 is connected to an air source (not shown). The hose 27 base 28 is attached to the frame 29 side holder 29.
It is supported by and is engaged. 23b is an arc-shaped valve groove provided in the valve case 23 in communication with the hole 23a,
It is provided on the same circumference as the circumference of the hole 24a of the valve ring 24, and the hole 24a is opposed to the valve groove 23a by starting the air source while the transfer cylinder 6 is rotating. The air is introduced into the nozzle pipe 26 only at some times, and the air is blown from the nozzle 25 at a predetermined timing. This timing is from when the leading nozzle row passes the counter contact with the upstream impression cylinder 2 and before the rear nozzle row reaches the counter contact with the downstream impression cylinder 5. Further, below the transfer cylinder 6, a paper guide 30 which is formed of a plate material and has a substantially equal length and a concentric circular arc shape is supported near the circumference of the cylinder. Air is blown from the nozzles 25 to the paper 22 that is gripped and conveyed by the paper 21, and the paper 22 is conveyed with its non-printing surface in sliding contact with the paper guide 30.

When each cylinder rotates and the air source is started, after printing, the impression cylinder 2
The paper 22 that is gripped and conveyed by the nail 3 of the
It is gripped and conveyed by the gripper 21, and further gripped by the claw 4 of the impression cylinder 5 and conveyed. As shown in the figure, the conveyed paper 22 is held by the peripheral surfaces of both the drums 2 and 6 at positions other than the gripping ends, and when the transfer cylinder 6 further rotates, the positions other than the gripping ends are released from the gripping. Will be retained. During this conveyance, the paper 22 is blown with air from the nozzle 25, and the portion other than the gripper end is conveyed in the same arc shape as the body circumference even if the body circumference is not covered. Also, the paper tail is both torso
After being released from the gripping of 2, 6, the non-printing surface is brought into contact with the paper guide 30 and conveyed at a portion other than the gripping end. Therefore, the printing surface of the paper 22 does not come into contact with anything and does not become dirty. Further, even when the downstream impression cylinder 5 is conveyed to the claw 4 after being gripped, the paper 22 is not exposed because the paper tail portion is conveyed in sliding contact with the paper guide.

ができる。As is apparent from the above description, according to the present invention, in the paper transporting device of the sheet-fed rotary printing press, the side plates fixed to both ends of the paper delivery cylinder and the gripper device at both ends support the paper delivery cylinder. The paper delivery cylinder is constituted by a claw holder fixed to the shaft and an air blowing nozzle which is held by the side plate so as to be located around the cylinder shaft and rotates integrally with the cylinder shaft and blows air in the radial direction. A paper guide that is formed in an arc shape along the outer circumference of the paper delivery cylinder and extends so as to be close to the counter contact of the mating cylinder is provided, and the paper delivery cylinder is open in the radial direction without being covered inside. As a result, the paper that is received from the other cylinder and gripped by the gripper device is blown toward the outside of the cylinder circumference by the air from the air blowing nozzle, and the paper is conveyed with only the non-printing surface attached to the paper guide. The surface touches anything Since the paper is conveyed without being soiled, the amount of waste paper generated is reduced and the air-blowing nozzle revolves around as the cylinder rotates. The conveyance is not disturbed, and the stain prevention effect is further increased. Further, when there is a cylinder on the downstream side of conveyance of the paper delivery cylinder, the paper is not brought into close contact with the cylinder when the paper is delivered to the cylinder, and the quality of the printed matter can be secured.
