2. Description of the Related Art In recent years, printed materials for advertisements, such as newspaper inserts, have been rapidly increasing. However, these printed materials are mainly printed by offset rotary presses in order to meet short delivery times and high quality. Have been. Most of this type of printed matter is cut in half or folded into one sheet. Therefore, if these printed materials are general ones using B-row paper, the rotary press cuts them into four-page signatures on B4 size or two pages on B4 size and discharges them.

FIG. 4 shows a folding machine of a commercial offset rotary press of the most standard B vertical series. The parallel folding section of this folding machine is composed of a folding cylinder 24 and a holding cylinder 25. The folding cylinder 24 is configured by providing two sets of the saw blade device 11, the needle device 10, and the folding blade device 17, respectively. The grip cylinder 25 includes two sets of the saw blade receiver 12 and the grip device 18. Each is provided.

The operation of the folding machine will be described. The continuous paper W which has been printed and sent to the folding machine enters between the folding cylinder 24 and the holding cylinder 25, and the front edge of the continuous paper W is folded. It is carried along the outer circumference of the folding cylinder 24 by the needle device 10 of the cylinder 24, and is rotated to a predetermined angle and released from the needle device 10. The continuous paper W released from the staple device 10 is folded at the predetermined position of the continuous paper W by the blade of the folding blade device 17. At this time, the blade of the folding blade device 17 is inserted into the gap between the holding plate of the holding device 18 and the jaw 25j of the holding drum main body to fold the continuous paper W. Then, the folded continuous paper W has a predetermined size between the saw blade device 11 of the folding cylinder 24 and the saw blade receiver 12 of the gripping cylinder 25, that is, B3.
Cut to length. Thus, the signature S folded in two to the size of four pages of B4 size as shown in FIG.
3 is formed. The folded signature S3 is conveyed at a constant pitch by the conveyor belt 29, and the impeller 9
Is discharged outside the machine.

When a sheet-shaped printed matter S1 is formed by using this folding machine, as shown in FIG. 5B, after the folded signature S3 is discharged out of the machine, the folding line of the signature S3 is cut. It is obtained by cutting the part with a separate cutting machine.
Therefore, as shown in FIG. 5 (a), the half-folded signature S3 formed by this type of folding machine has half of the sheet-shaped printed matter S1 as shown in FIG. 5 (b). The needle device 10 of the folding cylinder 24 is provided at the leading edge of each printed material.
The feature is that there is a mark of the needle hole caused by the above.

FIG. 6 shows a folding machine exclusively for sheet feeding in a commercial offset rotary press of the B-series. The cutting section of the folding machine includes a saw cylinder 7 provided with two sets of saw blade devices 11 and 2.

The stacking unit for stacking the cutting paper S1 cut to a predetermined length by two at this cutting unit is provided with three sets of claw devices 16a. It comprises a stacking cylinder 3 and a transfer cylinder 35 provided with three sets of claw devices 16c.

The operation of the folding machine will be described. The continuous paper W printed and sent to the folding machine is transferred between the saw blade 11 of the saw cylinder 7 and the saw blade receiver 12 of the receiving cylinder 8. Predetermined dimensions,
That is, it is cut into a B4 size length. The cut cutting paper S1 is conveyed along the outer periphery of the stacking cylinder 3 with its front edge held by the claw device 16a of the stacking cylinder 3, and is held in the claw device 16c of the transfer cylinder 35 every other copy. Will be replaced.
The cutting paper S1 that has not been transferred from the stacking cylinder 3 to the transfer cylinder 35 is conveyed while being overlapped with the subsequent cutting paper S1 that descends from the cutting section, and the claw device 16 of the transfer cylinder 35 is placed every other copy.
As a result, the two parts are held in a superposed state by a and are carried along the outer periphery of the transfer cylinder 35. Then, the cut paper S1 released from the claw device 16a at the predetermined position enters the impeller 9 in a state of being overlapped by two copies, and is discharged outside the machine via the discharge conveyor 14.

Therefore, the printed matter discharged from the folding machine, that is, the sheet of two pages of B4 size is discharged in a stack of two copies, so that the discharge can be performed without disturbance and the high-speed operation can be performed.
Moreover, there is no needle hole.

[0009]

As described above, as described above,
Conventional printing presses for commercial rotary presses have the following drawbacks when mainly printing flyers and the like. (A) The folding machine of the type having the folding cylinder 24 and the holding cylinder 25 can discharge the folded signature S3, but cannot output the sheet. When a sheet-like printed matter is formed by this folding machine, it is time-consuming and costly because the folded line of the signature S3 has to be cut by a separate cutting machine for the folded signature S3. In addition, the needle holes peculiar to the rotary press at the edges of these printed materials impair the appearance of the product. (B) A folding machine having a stacking cylinder 3 and a transfer cylinder 35 is capable of efficiently discharging a sheet-like printed matter without a needle hole without using a cutting machine as a post-processing device, but is a two-folded signature. Because of this, the use was limited.

The present invention solves the above problems,
It is also possible to take out the sheet and discharge the folded signature,
Further, it is an object of the present invention to provide a versatile rotary press with high productivity and high versatility.

[0011]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a first cutting means for cutting a continuous paper which is printed and sent to a predetermined length, and a first cutting means for cutting the continuous paper into a predetermined length. A second cutting unit that cuts at a double length, a stacking cylinder that stacks a plurality of sets of the cut sheets cut by the first cutting unit,
A folding cylinder that folds the cut paper cut by the second cutting means in half, a stacking cylinder and a path that is disposed at a position adjacent to the folding cylinder and that receives the cut paper stacked by the stacking cylinder; A transfer cylinder having a drive path that can be selectively switched to a path for receiving a folded signature formed by the folding cylinder, and a paper discharge unit that conveys a printed material discharged from the transfer cylinder and discharges the printed matter to the outside of the machine By selectively switching between the stacking cylinder side and the folding cylinder side, it is possible to perform sheet feeding and also to fold in two.

According to the present invention, by switching the drive path by the clutch, the sheet can be fed out and the sheet can be folded in two, so that the variety of uses is expanded. Also,
Since the folding machine of the present invention is not provided with a staple device, there is no staple hole peculiar to a rotary press in addition to sheet ejection and also at the edge of a two-fold printed material, so that the quality of the printed material is improved and post-processing equipment is improved. No cutting machine is required, which has a great effect on shortening delivery time and improving productivity.
