Description

  The present invention relates to a newspaper rotary press provided with an offset printing press and a digital printing press, and a digital printing press used therefor.

  In recent years, in newspapers (including newspaper leaflets as well as folded leaflets), in addition to fixed patterns (hereinafter also referred to as fixed patterns), patterns that have been changed for each part or multiple copies (hereinafter also referred to as variable patterns) Printing) is increasing. The variable pattern is, for example, a lottery number attached to a flyer with a prize or a coupon. Printing such variable patterns can increase the added value of newspaper.

  Conventionally, offset printing presses (hereinafter also simply referred to as rotary printing presses) have been used for newspaper printing because of low printing costs and high printing speeds. However, rotary printing presses require plates. Therefore, every time the pattern is changed, the plate must be changed, which is not suitable for printing a variable pattern. For this reason, a digital printing machine such as an inkjet printing machine that can print a digital source as it is without using a plate (that is, the printing pattern can be easily changed) is used for printing the variable pattern.

  As a large-sized digital printing machine that can be applied to printing newspapers including variable patterns, for example, there is a printed material creating apparatus disclosed in Patent Document 1.

  This is a large-scale digital printing machine disclosed in Patent Document 1 (see front page, FIGS. 3 and 5, etc. In the following description, reference numerals used in Patent Document 1 are shown in parentheses for reference). The printed material creating apparatus (1) includes a digital printing unit (3) having an inkjet printing mechanism (33), an angle bar mechanism (8), a sheet forming and stacking unit (7), and a section forming unit (4). Configured. The continuous paper W printed by the digital printing unit (3) is sorted by the angle bar mechanism (8) and selectively conveyed to the sheet forming and stacking unit (7) or the section forming unit (4). The continuous paper W conveyed to the sheet forming and accumulating unit (7) is cut along the width direction to form a single sheet-like printed matter (79). On the other hand, the continuous paper (W) conveyed to the section forming unit (4) is cut along the width direction, and is further formed into a signature section (48).

However, a digital printing machine generally has a higher printing cost than a rotary printing machine, and incurs a significant cost increase especially when printing a large amount like a newspaper. Therefore, it is conceivable that a rotary printing machine is installed next to the digital printing machine, a fixed pattern is printed by the rotary printing machine, and a variable pattern is printed by the digital printing machine.
However, in this case, it is necessary to prepare an installation space for a rotary printing press and an installation space for a digital printing press separately, so that a wide installation space is required. Moreover, since it is necessary to purchase both a large-sized digital printing press and a rotary printing press, the price of the whole equipment becomes expensive.

As a printer capable of improving the problems caused by arranging such a large digital printer and a rotary printing machine in parallel, there is a hybrid printing machine in which the digital printing machine and the rotary printing machine are integrated. In the hybrid printing press, the digital printing press and the rotary printing press can share some equipment such as transport equipment, thereby reducing the installation space and the cost of the equipment.
An example of such a hybrid printing machine is a web printing machine disclosed in Patent Document 2.

The folding machine control device 102 includes a saw cylinder control unit 102a and the like, and controls the operation of the saw cylinder 52 and the folding cylinder 53 of the folding machine 5, and controls, for example, the timing of the cross cutting of the saw cylinder 53. Is.
The ink jet printing control apparatus 103 moves the print head 33 of the ink jet printing machine 3 to a location corresponding to the page on which the variable picture is printed based on the picture information acquired from the production management apparatus 200.

Further, the inkjet printing control apparatus 103 acquires operation information regarding the web 10 </ b> A to be passed through the inkjet printing machine 3 from the production management apparatus, and based on this operation information, the timing for starting printing by the inkjet printing machine 3 (printing) The start timing is changed.
That is, the inkjet printing control apparatus 103 acquires the printing start timing information of the offset printing unit 20A from the offset printing control apparatus 101 as information for setting the printing start timing by the inkjet printing machine 3 (printing start timing information). Then, the cross cutting timing information of the web 10A is acquired from the saw cylinder control unit 102a, and either one of the print patterns of the web 10A passed through the inkjet printer 3 is included in the print pattern. The printing start timing by the inkjet printer 3 is determined based on the printing start timing information.

Specifically, the inkjet printing control apparatus 103 acquires the pattern information from the production management apparatus 200, and the pattern information of the web 10A that is passed through the inkjet printer 3 includes both a fixed pattern and a variable pattern. , The printing start timing of the inkjet printer 3 is determined based on the printing start timing information by the offset printing unit 20A.
On the other hand, when the design information of the web 10A acquired from the production management device 200 does not include a fixed design, the inkjet printing control device 103 is based on the cross-cutting timing information acquired from the saw drum control unit 102a. 3 print start timing is determined.
If only the fixed pattern is included in the print pattern of the web 10 that is passed through the offset printing unit 20A, the inkjet printer 3 does not perform printing, and the inkjet print control apparatus 103 determines the print start timing. Never do.

  Based on the information acquired from the production management apparatus 200, the web path control unit 104 is configured so that the overlapping order of the webs 10A and 10B conveyed from the offset printing units 20A to 20F is a predetermined order. 4 is controlled.

[1-3. Action / Effect]
According to the rotary press 1 of the first embodiment of the present invention, the following operations and effects can be obtained.
When the variable pattern is included in the printed pattern, the fixed pattern is offset printed by the offset printing unit 20, and the variable pattern is printed by the inkjet printer 3. The ink jet printer 3 is arranged facing the web conveyance path 11, and the conveyance path 11 is provided by a web supply unit (such as a paper feeding unit 21, an infeed unit 22, or a guide roller 25) attached to the offset printing unit 20. The variable pattern is printed on the web 10A being conveyed. That is, the web supply means is shared by the offset printing unit 20 (offset rotary printing machine 2) and the inkjet printing machine 3.
Further, the web 10A on which the variable pattern is printed by the ink jet printer 3 is changed in the overlapping order by the web pass unit 4 and the folding machine 5 attached to the offset printing unit 20, and is made a compromise.

That is, in addition to the web supply means, the web pass unit 4 and the folding machine 5 are shared by the offset printing unit 20 (offset rotary printing machine 2) and the inkjet printing machine 3.
Therefore, since the web supply means, the web path unit 4 and the folding machine 5 can be shared, an increase in the manufacturing cost of the rotary press and an increase in installation space due to the provision of the ink jet printer 3 can be suppressed. In particular, since the inkjet printer 3 is disposed above the offset printing unit 20A, it is not necessary to expand the installation floor area as compared with the conventional rotary press.

When the inkjet printing machine 3 is built in the rotary printing machine 2, the rotary printing machine 2 enters the inside of the inkjet printing machine 3. It is necessary to greatly change the structure of the rotary printing press 2 from the conventional structure, such as changing from the structure.
On the other hand, in the present invention, the inkjet printer 3 is disposed above the offset printing unit 2. That is, it is externally attached to the offset printing unit 2 and thus to the rotary printing press 2. Therefore, as compared with the case where the ink jet printer 3 is built in the rotary printing press 2, the structure of the general rotary printing press 2 can be used almost as it is for the rotary printing press 2. Furthermore, since the inkjet printing machine 3 does not enter the rotary printing machine 2, it is easy to access the inkjet printing machine 3 and secure a work space during maintenance of the inkjet printing machine 3. Therefore, maintenance of the inkjet printer 3 can be easily performed.

Furthermore, as described above, the same rotary printing press as that used for a general rotary printing press can be used, and the installation floor area associated with the ink jet printing press need not be expanded. It is possible to easily add a digital printing machine to the rotary press and modify it to the rotary press of the present invention.
For example, in the present embodiment, the rotary printing press 2 has a configuration in which a guide roller 25a for transporting the web 10A to the inlet of the inkjet printing press 3 is added to the conventional rotary printing press.

  In addition, since the printing width of the ink jet printer 3 is set to a size that allows printing one page of newspaper, a wide printable area can be taken, and all the pages of newspaper can be printed. The variation of the variable pattern can be increased. For example, in the past, only small designs such as lottery numbers and coupons attached to prize flyers could be printed as variable designs, but regional advertisements and articles for the region can be printed as variable designs. It is possible to subdivide the contents for each region and further increase the added value of newspaper.

In addition, since the ink jet printer 3 can print on a large area spanning the width of one page of newspaper, by using only the ink jet printer 3 and supplying paper of the corresponding width, other than newspaper It can be applied to full digital printing.
When only the inkjet printer 3 is used in this way, the offset printing units 20B to 20F other than the offset printing unit 20A sharing the web supply means with the inkjet printer 3 are stopped. Further, the offset printing unit 20 </ b> A does not perform printing in the printing unit 23.

  In addition, the print head 33 having a width smaller than the width of the web 10A conveyed to the ink jet printer 3 is configured to move along the width direction of the web 10A. In contrast, the variable pattern can be printed at an appropriate position on the web 10A while suppressing the cost of the expensive print head 33.

  Further, when a fixed pattern is printed on the web 10A by the offset printing unit 20A and a variable pattern is printed by the ink jet printer 3, the ink jet printer 3 uses the offset printing start timing information (the book after trial printing). The printing of the variable pattern is started at a timing based on the printing timing information). Thereby, a variable picture can be printed in accordance with the position of the fixed picture printed by the offset printing unit 20, and the positional relationship between the fixed picture and the variable picture can be accurately maintained.

  On the other hand, when printing a pattern on the web 10 </ b> A using only the ink jet printer 3, the ink jet printer 3 may start printing at a timing based on the timing at which the saw cylinder 52 performs the cross-cutting. it can. As a result, it is possible to print a pattern together with the portion cut by the saw cylinder, and to accurately maintain the positional relationship between the cut portion (that is, the end of the newspaper) and the variable pattern.

  Therefore, the print quality can be maintained in both cases where printing is performed using both the offset printing unit 20 and the inkjet printer 3 and when printing is performed using only the inkjet printer 3.

[2. Second Embodiment]
[2-1. Composition of newspaper rotary press]
A newspaper rotary press (hereinafter simply referred to as a rotary press) according to the second embodiment of the present invention is different from the rotary press according to the first embodiment in addition to the newspaper folding machine 5 in FIG. A folding machine (second folding machine) 5A is arranged next to the offset printing unit 20A as indicated by a chain line, and a printed web (for example, a web 10A on which a variable pattern is printed by at least the inkjet printing machine 3). Is guided by a guide roller (not shown) and supplied to the folding machine 5A.
Whereas the folding machine 5 is dedicated to newspaper, this folding machine 5A can create a web in a folding manner other than for newspaper. When folding specifications other than those for newspapers are performed (in other words, when printed matter other than newspapers is created), the inkjet printer 3 is often used. In this embodiment, the folding machine 5A is shown in FIG. As shown in FIG. 5, the inkjet printing machine 3 is disposed next to the offset printing unit 20A to which the inkjet printing machine 3 is attached. Of course, the folding machine 5A can also be used when printing is performed by the offset printing units 20A to 20F together with the inkjet printing machine 3.

The folding specifications other than those for newspapers are, for example, as follows, and a folding machine 5A that uses a web as a signature with such folding specifications is used.
(1) B4-2 page peller x2. That is, two double-sided printed sheets having a width dimension of 406 mm and a vertical dimension of 546 mm are cut into two to create two B4 size leaflets.
(2) B5-8 page fold. That is, a double-sided printed paper having a width dimension of 406 mm and a vertical dimension of 546 mm is folded twice into B5 × 8 pages.

Alternatively, a folding machine that can change the length of the signature or a folding machine that can change the number of pages of the signature is used in the folding machine 5A as a folding machine other than for newspaper. You may do it.
The folding machine, which can change the length of the crease, forms a crease by stacking the printed webs and then vertically folding and cross-cutting, and adjusts the rotation speed of the saw cylinder according to the print information of the printed matter By doing so, the length of the eclectic can be changed.
A folding machine capable of changing the number of pages of the folding sheet cuts a printed web with a saw cylinder into a sheet having a predetermined length, and uses a needle device to stack a predetermined number of sheets on the folding cylinder. Folding with an arbitrary number of pages can be created by folding with a cylinder and a folding roller.

[2-2. Action / Effect]
According to the rotary press of 2nd Embodiment of this invention, since the folding machine 5A which makes a web a signature by folding specifications other than for newspapers is provided, the variation of the signature which can be created can be increased.
If a folding machine that can change folding specifications (the length and number of pages) is used as the folding machine 5A as described above, the web can be folded with a folding specification other than that for newspaper. Since the web can be made into a signature with the folding specification for newspaper, when the folding machine 5 dedicated to newspaper breaks down, the folding machine 5A can be used to create newspaper.
