へ排紙される。[Related Art] In a rotary printing press, for example, when two types of pictures are arranged in the circumferential direction of a printing plate and printed at the same time, the web folded in a form is cut at the border of the pictures and alternately printed on a different discharge path. Is discharged. For this purpose, a folding machine conventionally attached to this type of rotary printing press is provided with a pair of left and right needle cylinders that are in contact with each other and a claw cylinder that is in contact with each of these cylinders. The cut web is alternately cut by the left and right needle cylinders, the cut portions are held by the needles, and each of the needle cylinders is replaced by the claws of the left and right nail cylinders, and is discharged to different discharge paths.

阻害されるという欠点があった。However, in such a signature dispensing device using a needle cylinder and a claw cylinder, there is a problem that a needle hole is left in a discharged printed material, and thus a cutting step for removing the needle hole is required. There is a drawback that the speeding is hindered because the pawl and the claw are operated by the cam.

のである。Accordingly, Japanese Patent Application Laid-Open No.
A signature distribution device disclosed in Japanese Patent Application Laid-Open No. 62-21670 has been proposed. This apparatus is provided with a fan-shaped rotator having an outer circumference trajectory facing between two upper and lower discharge paths. When the rotator faces between the upper and lower discharge paths, the signature is placed on the upper tier. The signature is discharged to the discharge path, and when the rotating body does not reach between the upper and lower discharge paths, the signature is discharged to the lower discharge path.

いたりするという問題がある。However, in such a conventional signature distributing apparatus, a fixed guide is required to avoid reverse slip between the transport belt provided on the paper discharge path and the signature transported by the transport belt. As a result, when the speed of the signature is increased, there is a problem that the high-speed signature and the stationary fixed guide rub against each other, and the signature is dirty or damaged. Also, due to the relationship between the signature and the rotating body, the circumference of the rotating body cannot be increased, so that the signature protrudes from the circumferential surface of the rotating body and comes into contact with the fixed guide, thereby becoming dirty or damaged. There is.

The sheet is conveyed while being pinched by the conveyor belt, and reaches a crossing start point with the trajectory of the rotating body. Here, the rotating body intermittently circulates, and when the rotating body and the transport signature correspond, the signature is pushed by the rotating body and transported to the second paper discharge path by the second and third transport belts, When the rotating body does not correspond to the transport signature, the signature is transported to the first paper discharge path by the first and fourth transport belts. Since there is no fixing member in the signature conveying path, and the setting of the peripheral surface length of the rotating body and the installation of the deflection roller, the signature does not interfere with the rotating body, so that the signature is not rubbed.

を経て排紙される。The operation of the signature distribution device configured as described above will be described. Rotate the diverter 6b, and move each conveyor belt 7, 13, 21, 23
After the printing operation is started, the web 1 that has been subjected to formal folding is cut by the cutting cylinder 2 and the cutting receiving cylinder 3 at the boundary between the plate and the boundary between the intermediate patterns, and the signature 7 is cut.
Then, the sheet is fed and conveyed between the conveying belts 7 and 13. In this case, the traveling speed of both conveyor belts 7, 13 is
, A predetermined interval is formed between the signature 4 to be conveyed and the next signature 4. As shown in FIG. 2 (a), the leading end of the conveyed signature 4 crosses the starting point P
Is reached, the leading end of the diverter 6b is also set to reach the crossing start point P.
To be fed between the second transport belt 13 and the third transport belt 23 and transported. FIG. 2 (b) is a diverter
The diverter 6b finishes pushing the signature 4 and retreats from the conveyance path, while the rear end of the cross section 6b reaches the crossing start point P, and the signature 4 continues to be conveyed and passes through the second paper discharge path. The paper is ejected.

Upon reaching the end point P 1 across the trailing edge of the diverter 6b as shown in FIG. 2 (c), signature 4 is caught up diverter
There is a risk of collision with the rear end portion of 6b, a variable over there conveyer passage of filtrate 24 is provided signature 4 in this apparatus, on the cross end point P 1 orbital trajectory 6c, across the start point P
In the case where it is assumed that the straight conveying direction of the divertor 6b is extended straight, it is bent in a U-shape so as to be positioned in the direction opposite to the rotation direction of the diverter 6b from the crossing end point, so that a collision may occur. Absent. The signature 4 is continuously conveyed and discharged through a first discharge path.

傷付かない。Thereafter, the above operation is repeated, so that the signatures 4 are alternately discharged and stacked on the first paper discharge path side and the second paper discharge path side. In the conveying path of the signature 4 distributed and conveyed in this manner, there is no fixing member as in the related art.
And the transport belts 7, 13, 21, and 23 do not slip, so that the signature 4 is not rubbed. Further, as described with reference to FIG. 2 (c), the diverter 6b evades the signature 4, so that the signature 4 is not damaged.

機の折丁分配装置。1. A plurality of rotating bodies formed in a fan shape having an arc portion having a length substantially equal to the length of a signature, driven in rotation from a driving side, and arranged in parallel in an axial direction of a shaft serving as a center of rotation; These rotators and the positions of these rotators are changed in the axial direction, and the trajectory formed by the rotation of the rotator is traversed linearly at the traverse start point and the traverse end point from the traverse start point. A plurality of first conveyor belts stretched through a paper input section on the upstream side in the conveying direction of the signature and a first discharge path entrance on the downstream side in the conveying direction of the signature from the crossing end point; A plurality of second belts which are stretched in contact with one conveyor belt and are separated from the first conveyor belt at a starting point of crossing with the loop locus and stretched in a tangential direction of the loop locus toward a second paper discharge path. The transport belt and each second transport after the crossing start point The in and bears against the belt stretching been plural rows 3 conveyor belts and, each of the first and subsequent start point the cross
In the case where it is assumed that a plurality of fourth conveyance belts stretched in contact with the conveyance belt and the crossing end point extends straight on the orbital trajectory, the straight conveyance direction at the crossing start point. A deflecting roller for bending the first transport belt and the fourth transport belt into a V-shape in a trajectory so as to be positioned in a direction opposite to a rotation direction of the rotating body from a crossing end point; A signature distribution device for a rotary printing press.
