Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial application field) The present invention relates to a paper feeder applied to a newspaper rotary printing press of the same floor type.

(Prior art) The conventional paper feeder of the same type of rotary press has two arms and an automatic splicing device, and automatically winds up the webs attached to the two arms sequentially. The paper is continuously fed to the same floor type rotary press.

(Problem to be Solved by the Invention) The conventional paper feeder of the same-floor type rotary press has the following problems. That is, the paper feeder of a high-speed newspaper rotary printing press used by newspaper publishers with a large number of prints is designed to mount a large-diameter web (a large-diameter web of 1270 mm in diameter) in order to reduce the number of splicing. ing. However, newspaper publishers with a small number of copies can cover all of the number of copies with a single large-diameter web. The printing press becomes expensive. For this reason, there is a demand for a fixed-type single-arm feeder which can be loaded with a large-diameter web but has a simple structure without a splicer. On the other hand, depending on the number of pages and the number of prints, there may be a case where the entire web is not consumed and remains. This remaining paper must be used, but the remaining paper cannot cover the number of copies to be issued, so do not stop the rotary printing press during printing by splicing the remaining paper or the remaining paper with the new paper roll. Need to be

The present invention has been made in view of the above problems, and its purpose is to reduce the cost of a rotary printing press. Another object of the present invention is to provide a sheet feeding device for a rotary printing press capable of improving the operation rate of the rotary printing press.

(Means for Solving the Problems) In order to achieve the above object, the paper feeder of the rotary printing press according to the present invention includes a paper feeder of a plurality of paper feeders installed in the rotary printer. The apparatus is a paper feeder having an automatic paper splicer, the remaining paper feeders are stationary paper feeders without the automatic paper splicer, and these paper feeders are arranged along a web handling line.

(Operation) The paper feeder of the rotary printing press according to the present invention is configured as described above, and the new paper roll is transported to all paper feeder positions by the paper roll handling line, is removed from the paper roll handling line, and all paper feeds are performed. Attach it to a paper device and print. When the remaining paper is generated in the stationary paper feeder without the automatic splicing device, the remaining paper is conveyed to the position of the paper feeding device having the automatic paper splicing device by the web handling line.
It is detached from the web handling line, attached to a paper feeder having an automatic paper splicing device, and printing is continued while performing automatic paper splicing.

(Embodiment) Next, a paper feeder of a rotary printing press according to the present invention will be described with reference to an embodiment shown in FIGS.
(See (1a) to (1e)) in parallel with 5 sets of black printing units (2) and one folding machine (4) arranged in a row and corresponding to each black printing unit (2) Are arranged on the same floor. (1a) (1
b) is a paper feeder having two arms (31) and an automatic paper splicing device (32), and (1c), (1d), and (1e) are stationary paper feeders without an automatic paper splicing device. Also multi-color printing nits (3)
(See (3a)) is also arranged on the same floor opposite to the paper feeder (1) and parallel to the black printing unit (2). The multicolor printing unit (3b) indicated by the broken line is the scheduled reprint. In addition, a multi-stage guide roller (6) provided between the ink printing units (2), and a stationary deflection for a traveling paper having a width half the width of a web provided at the top of each ink printing unit (2). A tumbler (7) and a moving tumbler (1) for inserting the running paper from the multi-color printing unit (3) into an arbitrary position according to the editing.
A web path (5) composed of 1) and a compensating tower (compensating roller group) (8) is placed on a black printing unit (2) and a folder (4). A drive shaft (drive) (9) having a motor (12), a drive gear (13) and a bearing (14), and a multicolor printing unit (3)
(15) and a drive shaft (9 ') having a drive gear (16) are installed above the black printing unit (2), folding machine (4) and multicolor printing unit (3), respectively. . A web handling line (18) is also provided on the same floor as the paper feeder (1). In addition, pit (17)
Is used for loading and unloading of printing members and machine parts.
At the time of printing, the running paper (see the dashed line) fed from the full-width web (width 1626 mm) mounted on the paper feeder (1) is guided to the black printing unit (2) via the lower pit (20). After printing in, it is cut in half width direction and guided to the tumbler (7). Here, the traveling direction is changed by 90 °, the phase of the traveling direction is adjusted by the compen tower (8), and guided to the folding machine (4). When performing multi-color printing with the multi-color printing unit (3), the traveling paper from the paper feeding device (1) is guided from the upper part of the black printing unit (2) to the upper part of the multi-color printing unit (3), and then the multi-color printing is performed. It comes out again from the upper part of the multicolor printing unit (3), and is guided to the folding machine (4) via the movable diverter (11) → the compensator (8). In other words, the movable diverter (11) is raised and lowered so that multicolor printing is performed at a position corresponding to the editing. The tumbler (21) is provided on the output side of the multicolor printing unit (3) to reverse the front and back of the multicolor printing.

Next, the operation of the sheet feeding device of the rotary printing press shown in FIGS. 1 and 2 will be specifically described. Web handling line (18)
Transports the new web to all paper feeders (1a) to (1e), removes it from the web handling line (18), attaches it to all paper feeders (1a) to (1e), and prints. Do. When the remaining paper is generated in the stationary paper feeder (1c) (1d) (1e) without the automatic paper splicing device (32), the remaining paper is transferred to the automatic paper splicing device (3
Conveyed to the position of the paper feeder (1a) (1b) having 2),
It is detached from the web handling line (18), and is mounted on the paper feeder (1a) (1b) having the automatic paper splicing device (32), and printing is continued while performing automatic paper splicing.

(Effects of the Invention) The paper feeder of the rotary printing press of the present invention transports a new web to all paper feeder positions by the web handling line as described above, removes it from the web handling line, and sends it to all paper feeders. Attach and print. Then, if residual paper is generated in a stationary paper feeder without an automatic paper splicer,
The remaining paper is transported by the web handling line to the paper feeder position with the automatic paper splicing device, removed from the web handling line, installed in the paper feeding device with the automatic paper splicing device, and printed while performing automatic paper splicing. Since the continuation is continued, it is not necessary to use all the paper feeding devices as the paper feeding devices having the automatic paper splicing device, so that the rotary printing press can be made inexpensive.

In addition, it is possible to prevent the rotary printing press from being stopped during printing by splicing the remaining papers or the remaining paper with the new winding paper, thereby improving the operation rate of the rotary printing press.
