JP 2007-296850 A

  In the above-described conventional newspaper offset rotary printing press, it is a future problem to make the printing apparatus or the entire printing press compact.

  SUMMARY An advantage of some aspects of the invention is to provide a printing machine and a printing method that can make the printing apparatus or the printing machine compact.

  In order to achieve the above object, a printing machine according to the present invention includes a paper feeding device that supplies a web, a printing device that performs printing on the web fed from the paper feeding device using a printing cylinder, and A folding machine that forms a fold by cutting and overlapping the web printed by a printing device, and the circumference of the printing cylinder has a size in the longitudinal direction of a broad-type printed matter The width of the printing cylinder is set to be substantially an integral multiple of the size in the vertical direction of the broad-format printed matter.

Accordingly, it is possible to realize a compact printing apparatus or printing machine as a whole.
In addition, if the circumference of the printing cylinder is set to an appropriate approximate integer multiple of the size in the longitudinal direction of the printed material in the broad format and the width of the printing cylinder in the vertical direction of the printed material in the broad format, The printed material has almost the same size as the conventional one, and more printed pages than the conventional one can be obtained. In other words, it is possible to print more pages than before on one web (web). In other words, it is possible to increase the number of pages that can be printed by one printing unit as compared with the conventional case. As a result, multi-page printing equivalent to the conventional one can be realized with a smaller number of printing apparatuses than before, and thus the printing apparatus or the entire printing machine can be made compact. In this case, since the maximum paper width equivalent to the conventional one has a relationship with a substantially integer multiple of the vertical dimension of the broad format printed matter, if an appropriate multiple is selected (for example, three times the vertical dimension of the broad format printed matter) It is also possible to use a web having the maximum paper width as before.

  In the printing machine of the present invention, the printing apparatus includes a plate cylinder on which a printing plate is mounted, and a blanket cylinder that transfers ink of the plate cylinder to the web, and the circumference of the plate cylinder is usable. It is characterized by being set to a size approximately n / 2 times the maximum paper width of the web (n is a natural number).

  Therefore, by setting the circumference of the plate cylinder to be approximately n / 2 times the maximum paper width of the web (n is a natural number), the circumference of the plate cylinder and the maximum paper width (the length of the plate cylinder in the axial direction) are set. )) And a suitable combination of plate cylinder diameter and plate cylinder width. As a result, it is possible to prevent an increase in the size of the printing apparatus or an increase in the size of the entire printing apparatus or the printing press despite the multi-page correspondence. That is, 1.5 pages more pages than before can be printed on one web (web). For example, when converted into a reel of winding paper, printing equivalent to 6 reels can be performed with 4 reels. Therefore, the printing machine of the present invention capable of printing the same page as the conventional machine has a printing unit more than the conventional machine. Therefore, it is possible to prevent the printing apparatus or the entire printing machine from becoming large. As described above, if the number of printing units can be reduced, the arrangement of operators can be integrated, so that it is possible to reduce the number of operators of the printing press. Further, it is possible to use a web having the maximum paper width as in the conventional case, which is convenient.

  The printing press according to the present invention is characterized in that n is 1 or 2.

  Therefore, the size of the plate cylinder can be optimized for the printing apparatus. That is, a printing apparatus conventionally used as a general-purpose machine is a so-called 4 × 1 machine in which a printing plate capable of printing one page in the circumferential direction of the plate cylinder and four pages in the longitudinal direction is mounted ( A so-called 4 × 2 machine (a two-page circumference plate) equipped with a printing plate capable of printing two pages in the circumferential direction of the plate cylinder and four pages in the longitudinal direction. It is possible to print more pages than a conventional web while optimizing the size of the plate cylinder corresponding to this printing apparatus.

  In the printing machine of the present invention, a web pass device is provided that vertically cuts the printed web and then overlaps, and the folding machine horizontally cuts a plurality of webs that are vertically cut and are not vertically folded, It is characterized in that a printed product is formed by horizontally folding and then vertically folding.

Therefore, similarly to the conventional printing press, the printed web can be vertically cut and stacked using the web pass device, and the printing device, the printing device, or the entire printing press can be made compact.
Usually, a newspaper press is often composed of a combination of a single color printing unit and a color printing unit. In this case, in order to put a color page in a desired position when creating a printed matter of a newspaper. A bay window device is required. On the other hand, when the printing apparatus of the present invention is a color printing apparatus, the number of color pages can be increased. Therefore, it is possible to reduce the number of single-color printing units and configure only a color printing unit. It becomes possible. In this case, it is not always necessary to provide a bay window device, and the web pass device can be simplified.

  In the printing machine according to the present invention, the folding machine includes a cutter device that longitudinally cuts a printed web, horizontally cuts a plurality of webs that have been vertically cut and stacked, and then horizontally folds and then vertically folds. It is characterized by forming printed matter.

  Therefore, it is possible to perform not only the broad format printing but also the tabloid format printing simply by providing the folding device with the cutter device.

  In the printing machine of the present invention, the folding machine includes a cutter device that longitudinally cuts a printed web, and a plurality of webs that have been longitudinally cut and stacked, and then horizontally cut, horizontally folded, and vertically folded to generate a broad-type printed matter. It has the 1st conveyance path | route to form and the 2nd conveyance path | route which forms the tabloid type printed matter by carrying out the horizontal cutting and the vertical folding of the some web piled up longitudinally.

  Therefore, not only the broad format printed matter but also the tabloid type printed matter can be printed, and the versatility of the apparatus can be improved.

  In the printing machine of the present invention, the printing apparatus includes a plurality of printing units, and the folding machine includes a plurality of cutter apparatuses that vertically cut a printed web and a plurality of webs that are vertically cut and overlapped. It is characterized by having a plurality of conveyance paths for forming printed matter by cutting and folding, and a distribution mechanism for distributing the web vertically cut by the cutter device by the plurality of conveyance paths.

  Accordingly, it is possible to simultaneously print a plurality of types of printed matter. In addition, the sorting device that sorts a plurality of transport paths increases the number of variations of the printed material that can be created.

  In the printing machine according to the aspect of the invention, the cutter device horizontally arranges the first triangular plate and the second triangular plate having a size that is divided into two equal parts at the half of the bottom of the first triangular plate. It arrange | positions as a guide board by this, and it is characterized by comprising at least 2 cutters arrange | positioned at equal intervals on the upper part.

  Therefore, the web can be cut vertically and properly cut by using the existing arrangement of the triangular plates conventionally used as the folding machine and by properly arranging the cutter. The web can be guided appropriately.

  Further, the printing machine of the present invention includes a sheet feeding device having a plurality of independently driven paper feeding units, a printing device having a plurality of independently driven printing units, and a plurality of printed webs by vertically cutting a plurality of printed webs. A sheet feeding device including: a sorting device that sorts the feeding path; and a folding machine that has a plurality of folding units capable of creating a plurality of signatures by independently cutting and overlapping each of the sorted webs. And a printing machine capable of simultaneously producing a plurality of printed materials at different speeds by driving and controlling the printing device, the sorting device, and the folding machine, wherein the circumference of the printing cylinder is the size in the longitudinal direction of the broad-type printed material The width of the printing cylinder is set to be substantially an integer multiple of the size in the vertical direction of the broad-format printed matter.

Therefore, not only can the printing apparatus or the printing machine be made compact, but also different types of printed matter can be created simultaneously in each unit. In addition, the sorting device that sorts a plurality of transport paths increases the number of variations of the printed material that can be created.
Note that when different types of printed matter are created simultaneously by one printing machine, the print job (print lot) changes more frequently than when one printed matter is printed by one printing press. On the other hand, by adjusting the circumference of the printing cylinder to the size in the longitudinal direction of the broad-format printed matter and setting the width of the printing cylinder appropriately to the size in the vertical direction of the broad-type printed matter, More pages can be collected in one printing unit. That is, the place (printing unit) where the plate is exchanged is also gathered. Therefore, when different types of printed matter are simultaneously printed, the work efficiency can be improved and the preparation time can be shortened even when the print job changes frequently.
By setting the circumference of the printing cylinder to the size in the longitudinal direction of the printed material in the broad format and setting the width of the printing cylinder in accordance with the size in the vertical direction of the printed material in the broad format, A printed matter of a type can be formed with approximately the same size as before and with more printed pages than before. As a result, the entire printing apparatus or printing press can be made compact.
Further, for example, the number of printing units can be reduced as compared with the conventional machine, and the printing apparatus or the entire printing machine can be made compact, so that control when simultaneously printing different types of printed matter can be made simpler than before. it can.

  Also, the printing method of the present invention is such that the longitudinal direction of the broad-format printed matter is the web conveyance direction, and an approximately integral multiple of the size of the broad-type printed matter in the longitudinal direction is the width direction of the printing cylinder. Printing on the web is performed by a printing apparatus corresponding to the size.

Accordingly, not only can the printing apparatus or the printing machine be made compact, but also the longitudinal direction of the broad-format printed matter is the web transport direction, and is approximately an integral multiple of the size of the broad-type printed matter in the longitudinal direction. However, when printing on a web using a printing apparatus corresponding to the size of the printing cylinder in the width direction, when a broad-type printed matter is created, a product having approximately the same size as the conventional one can be obtained.
Note that when the size in the width direction of the printing cylinder is set to an appropriate value (for example, about 3) when the relationship is approximately an integral multiple of the size in the vertical direction of the printed material in the broad format, one web (web) ), It is possible to print more pages than in the past. In other words, it is possible to increase the number of pages that can be printed by one printing unit as compared with the conventional case. As a result, multi-page printing equivalent to the conventional one can be realized with a smaller number of printing apparatuses than before, and thus the printing apparatus or the entire printing machine can be made compact.

  In the printing method of the present invention, the printed web is vertically cut and stacked, the plurality of stacked webs that are not vertically folded are horizontally cut, horizontally folded, and then vertically folded to produce a broad-type printed matter. It is characterized by forming.

  Accordingly, it is possible to easily print a broad-type printed matter.

  The printing method of the present invention is characterized in that a printed web is vertically cut and then stacked, a plurality of overlapped webs are horizontally cut, and vertically folded to form a tabloid printed matter.

  Therefore, it is possible to easily print a tabloid type printed matter.

  According to the printing machine and the printing method of the present invention, the circumference of the printing cylinder is set to be approximately an integer multiple of the size in the longitudinal direction of the broad format printed matter, and the width of the printing cylinder is set to be the vertical direction of the broad format printed matter. Since the printing is performed on the web so that the longitudinal direction of the broad-format printed matter is the web conveyance direction, the printing apparatus or the printing machine as a whole can be made compact. it can.

  Accordingly, by interlocking the saw cylinder 43, the folding cylinder 44, and the saddle cylinder 45, a plurality of stacked webs W are cut horizontally, and then folded horizontally and then vertically folded by the chopper folding device 33 to serve as a newspaper. Is produced. The detailed operation of the folding machine F will be described later.

  By the way, conventionally, when producing a broad-type newspaper, as shown in FIG. 6A, a web W having a width W of 1626 mm is used, and the longitudinal direction (width direction) of the newspaper is the width direction of the web W. In addition, printing is performed on the web W. That is, two types of printing plates are attached to the plate cylinder side by side in the axial direction of the plate cylinder so that the vertical direction is the circumferential direction of the plate cylinder. When printing is performed using two plate cylinders, the web W is printed so that the top and bottom direction of the newspaper is the longitudinal direction of the web W. Then, the printed web W is vertically cut at the central portion in the width direction and then overlapped, and further overlapped with a plurality of webs W printed by another printing unit, and then horizontally cut at a predetermined position. Newspapers are produced by vertical folding and then horizontal folding. In this case, the length H1 in the vertical direction of the newspaper is 546 mm, and the length W1 in the left-right direction (width direction) is 813 mm.

  However, in this case, since only one type of printing plate can be mounted in the axial direction in one printing cylinder, a single printing unit can generate a newspaper of up to 8 pages by using two printing plates. Production is the limit. Therefore, when a 24-page newspaper is manufactured, three printing units are required, and when a 48-page newspaper is manufactured, six printing units are required.

  Therefore, in Example 1, when a broad-type newspaper is manufactured, as shown in FIG. 6B, a web W having a width W of 1626 mm is used as in the conventional case, and the longitudinal direction (width direction) of the newspaper is Printing is performed on the web W so as to be in the conveyance direction of the web W. That is, three types of printing plates are attached to the plate cylinder side by side in the axial direction of the plate cylinder so that the vertical direction is the axial direction of the plate cylinder. When printing is performed using two plate cylinders, the web W is printed on the front surface and the back surface thereof so that the vertical direction of the newspaper is the width direction of the web W. Then, the printed web W is vertically cut at the central portion in the width direction and then overlapped, and further overlapped with a plurality of webs W printed by another printing unit, and then horizontally cut at a predetermined position. Newspapers are produced by vertical folding and then horizontal folding. In this case, the length H1 in the vertical direction of the newspaper is 542 mm, and the length W1 in the left-right direction (width direction) is 813 mm.

  That is, in the newspaper offset rotary printing press 10 of the first embodiment, the circumferential length of the plate cylinder 12 as a printing cylinder is set to be approximately an integral multiple of the size in the longitudinal direction of a broad-type newspaper (printed material). At the same time, the width of the plate cylinder 12 is set to be approximately an integral multiple of the vertical size of the broad-format newspaper (printed material). In this case, the multiple m, which is a substantially integer multiple, is a natural number, preferably m = 1 to 4, and actually m = 1 to 2 is optimal.

  Specifically, as described above, the width W of the web W is 1626 mm, and a broad-type newspaper has a size of about 546 mm in length and about 813 mm in width. Therefore, when m = 1, the circumferential length of the plate cylinder 12 is about 813 mm, which is a size in the longitudinal direction of a broad-type newspaper, that is, one time of a width (horizontal length) of 813 mm. When m = 2, the circumferential length of the plate cylinder 12 is about 1626 mm, which is twice the size in the longitudinal direction of the broad newspaper, that is, the width (horizontal length) of 813 mm.

  Note that, as described above, the conventional plate cylinder performs printing so that the longitudinal direction (width direction) of the newspaper is the width direction of the web W, so that the circumference is about 546 mm in length or twice that length. Of about 1092 mm. Therefore, a plate cylinder having a circumference of about 546 mm is approximately 0.67 (546 / (1626/2)) times the circumference of a broad-type newspaper, and a plate having a circumference of about 1092 mm. The trunk is approximately 1.34 (1092 / (1626/2)) times as long as the circumference of a broad-type newspaper.

  The circumferential length of the plate cylinder 12 is set to be approximately n / 2 times the maximum paper width of the usable web W. In this case, n is preferably 1 or 2. When the circumference of the conventional plate cylinder is about 546 mm in length, n is about 0.33 (546/1626), and when the circumference is about 1092 mm, n is about 0.67 (1092/1626). is there. In this case, the web W obtained by winding the web W by a predetermined length is mounted and transported on a truck or the like, and this web is mounted so that the width direction (axial direction) is the vehicle width direction of the truck. . Therefore, the maximum width of the web is defined according to the width of the road on which the truck travels, and the usable web W is defined.

  It should be noted that the circumference of the plate cylinder 12 as a printing cylinder is approximately an integral multiple of the longitudinal size of the broad newspaper, and the circumference of the plate cylinder 12 is approximately n / 2 of the maximum paper width of the web W that can be used. Double and "abbreviated" are explained. Generally, the maximum paper width of the usable web W is 1626 mm, but the width of the web W may be slightly different depending on the manufacturer, and the width (size in the longitudinal direction) of the newspaper may be different. Further, the plate cylinder 12 and the blanket cylinder for printing on the web W are designed to have a slightly larger width (length in the axial direction), and therefore are described with “abbreviated” here.

  Here, the broad-format newspaper refers to a newspaper spread (also referred to as a broad format or a blanket format). Broad format newspapers in Japan are generally 546 × 813 mm, but in the case of the broad format in this embodiment, the newspaper has a size of about 542 mm in length and about 813 mm in width. A tabloid-type newspaper (also referred to as a tabloid format) is a newspaper having a half size of a broad-type newspaper, that is, a size of about 406 mm in length and about 542 mm in this embodiment. Note that the tabloid format is a format in which a cut is made at the vertical folding position of the broad format and rotated 90 degrees so that the horizontal folding position is at the back. In other words, it is almost the same size as the conventional format. In the case of the present embodiment, it is slightly compact without changing the width (lateral) dimension, and paper resources can be reduced.

  A newspaper printing method using the newspaper offset rotary printing press according to the first embodiment will be described below. Here, a case where a 48-page newspaper is printed using two printing units U1 and U2 by a newspaper offset rotary printing press will be described.

  In the first embodiment, as shown in FIG. 3, in a printing unit having a plate cylinder 12 and a blanket cylinder 13, six types of printing plates 14a, 14b, 15a, 15b, 16a, 16b (or printing plates 14a, 14b, printing plates 15a, 15b, printing plates 16a, 16b are respectively integrated printing plates 14, 15, 16), and the vertical direction thereof is the axial direction of the plate cylinder 12. The three printing plates 14a, 15a, 16a are mounted side by side in the axial direction of the plate cylinder 12, and the three printing plates 14b, 15b, 16b are arranged in the axial direction at positions shifted by 180 degrees in the circumferential direction of the plate cylinder 12. Install 16b. Note that the printing plates 14a and 14b, the printing plates 15a and 15b, and the printing plates 16a and 16b may be integrally formed to form three types.

  Then, printing is performed on the web W as shown in FIG. 4 by performing printing using the plate cylinder 12 to which the six types of printing plates 14a, 14b, 15a, 15b, 16a, and 16b are attached. Is called. In an actual printing unit, the ink supplied to the plate cylinder 12 (press plates 14a, 14b, 15a, 15b, 16a, 16b) is transferred to the web W via the blanket cylinder 13. In FIG. 4, the blanket cylinder 13 is omitted so that the relationship between each printing plate 14a, 14b, 15a, 15b, 16a, 16b mounted on the plate cylinder 12 and the image printed on the web W becomes clear. .

  Further, the sizes of the printing plates 14a, 14b, 15a, 15b, 16a, and 16b are set in accordance with the spread size of the broad newspaper. The printing plate 14a can transfer two pages of images (inks) A1 and A2 to the web W. Similarly, the printing plate 14b can print two pages of images A3 and A4, and the printing plate 15a can Two pages of images B1 and B2, the printing plate 15b has two pages of images B3 and B4, the printing plate 16a has two pages of images C1 and C2, and the printing plate 16b has two pages of images. C3 and C4 can be transferred to the web W, respectively.

  That is, when the plate cylinder 12 rotates, the printing plates 14a, 15a, 16a transfer the images A1, B1, C1, and the images A2, B2, C2 to the web W in order, and then the printing plates 14b, 15b, 16b transfers images A3, B3, C3 and images A4, B4, C4 in order. Further, when the plate cylinder 12 rotates, a continuous image is transferred by this repetition.

  Then, the web W is cut | disconnected along the vertical direction by A row | line | column, B row | line | column, and C row | line | column, and is isolate | separated into the three web Ws. Then, the three webs W are overlapped, and the three webs W printed and cut by another printing unit are overlapped to adjust the position in the transport direction. In this state, the paper is cut horizontally, and the images A1, A2, A3, A4, B1, B2, B3, B4, C1, C2, C3, and C4 are overlapped and passed through the folding machine with the collecttran setting. As shown in FIG. 5, twelve sheets S are stacked, and the bundle of sheets S is folded horizontally and then vertically folded, whereby a 48-page newspaper N can be manufactured.

  Hereinafter, a newspaper production method (printing method) using the above-described newspaper offset rotary printing press 10 according to the first embodiment will be specifically described.

  In the newspaper offset rotary printing press 10 according to the first embodiment, as illustrated in FIG. 1, the paper feeding device R operates the two paper feeding units R <b> 1 and R <b> 2 to supply the web W to the printing device U, respectively. Then, each printing unit U1, U2 in the printing apparatus U performs printing on the front and back of each supplied web W. At this time, as described above, the printing units U1 and U2 have six types of printing plates 14a, 14b, 15a, 15b, 16a, and 16b (or printing plates 14, 15, and 16), and the top and bottom directions are plate cylinders. Since the plate cylinder 12 is mounted side by side in the axial direction and the circumferential direction so as to be in the axial direction of 12, the web W is printed so that the longitudinal direction of the newspaper is the conveyance direction of the web W. Done.

  Subsequently, each printed web W is transported to the web pass device D. In each of the web pass units D1 and D2, the web W is vertically cut into three by each slitter 22, and the transport path is changed by the turn bar 23. Then, after the position of each web W in the conveyance direction is adjusted by the compensator 24, the sheets are superimposed in a predetermined order. When six webs W are overlapped by the web pass device D, they are conveyed to the folding machine F in this state.

  In this folding machine F, as shown in FIG. 2, first, the needle device 53a of the folding cylinder 44 is actuated to cause the needle to protrude outward, so that the leading end of the web W is pierced and held. If the saw cylinder 43 and the folding cylinder 44 continue to rotate from this state, the web W moves while being held on the peripheral surface of the folding cylinder 44. When the saw blade 51b of the saw body 43 and the saw blade receiver 52b are opposed to and coincide with each other at a predetermined position, the web W is cut by the saw blade 51b to form the sheet bundle S1. Simultaneously with the horizontal cutting by the saw blade 51b, the needle device 53b is operated to cause the needle to protrude outward, so that the tip of the web W is pierced and held.

  Subsequently, when the needle device 53a stabs and holds the leading end of the sheet bundle S1, and the needle device 53b stabs and holds the leading end of the web W, when the saw cylinder 43 and the folding cylinder 44 continue to rotate, The sheet bundle S1 and the web W move while being held on the peripheral surface of the folding cylinder 44. When the saw blade 51a of the saw body 43 and the saw blade receiver 52c face each other and coincide with each other at a predetermined position, the web W is cut by the saw blade 51a to form a sheet bundle S2. Simultaneously with the horizontal cutting by the saw blade 51a, the needle device 53 is operated to cause the needle to protrude outward, whereby the tip of the web W is pierced and held.

  Further, the needle devices 53a and 53b stab and hold the leading ends of the sheet bundles S1 and S2, respectively, and the saw cylinder 43 and the folding cylinder 44 rotate from the state where the needle device 53c stabs and holds the leading end of the web W. If it continues, sheet bundle S1, S2 and the web W will move, with the peripheral surface of the folding cylinder 44 being hold | maintained. When the saw blade 51b of the saw barrel 43 and the saw blade receiver 52a face each other at a predetermined position and coincide with each other, the web W is cut by the saw blade 51b to form a sheet bundle S1. Simultaneously with the horizontal cutting by the saw blade 51b, the needle device 53a protruding outwardly pierces and holds the leading end portion of the web W while piercing the leading end portion of the sheet S1.

  By continuing this operation only while the saw cylinder 43 is rotated three times and the folding cylinder 44 is rotated twice, two kinds of sheet bundles S1 and S2 are stacked on the folding cylinder 44 (collector folding). That is, since the plate cylinder 12 is mounted with two types of printing plates arranged along the circumferential direction, the three vertically cut webs W are printed with different images alternately. Yes. On the other hand, since the folding cylinder 44 is a triple cylinder, by rotating the folding cylinder 44 twice, three sets of two sheets of sheet bundles S1 and S2 stacked on the folding cylinder 44 are formed. It will be.

  Then, three sets of two types of sheet bundles S1, S2 are formed on the folding cylinder 44, and at the same time, the tips of the two types of sheet bundles S1, S2 are returned by returning the needles of the needle device 53a. Is released, and the folding blade 55a is advanced so that the leading end protrudes outward from the circumferential surface of the folding cylinder 44, whereby the stacked sheet bundles S1 and S2 are moved downward from the circumferential surface of the folding cylinder 44. Tear off. Then, when the folding blade 55a and the gripping device 57a coincide with each other, the gripping drum 45 rotating in synchronization with the folding drum 44 causes the sheet gripping device 57a to project the sheet bundles S1 and S2 protruding from the peripheral surface of the folding drum 44. The signature N is formed by holding and holding.

  Then, the signature N folded in half by the folding drum 44 and the collar drum 45 is transported on the chopper table 61 by the upper and lower transport conveyors 62 and 63 and stops at the position where the tip end abuts against the stopper 65. Then, the chopper blade 66 descends with respect to the signature N that stops at the reference position on the chopper table 61 by the driving device, and the central portion of the signature N is pushed into the slit 64 of the chopper table 61. The pair of folding rollers 67 sandwich the signature N and pass it while folding, so that a newspaper as the folded signature N is produced.

  As described above, in the newspaper offset rotary printing press according to the first embodiment, the sheet feeding device R that supplies the web W, and the plate cylinder 12 and the blanket cylinder 13 with respect to the web W fed out from the sheet feeding device R are provided. A printing apparatus U that performs printing, and a folding machine F that forms a newspaper by cutting and overlapping the web W printed by the printing apparatus U. The size of the format newspaper is set to an approximately integer multiple of the longitudinal direction, and the width of the plate cylinder 12 is set to an approximately integer multiple of the size of the broad format newspaper in the longitudinal direction.

  Accordingly, when the circumferential length of the plate cylinder 12 is set to an appropriate substantially integer multiple of the size in the longitudinal direction of the broad format newspaper and the width of the plate cylinder 12 in the vertical direction of the broad format newspaper, A type of newspaper can obtain almost the same size as the conventional newspaper and more printed pages than before. In other words, it is possible to print more pages on one web W than before. In other words, it is possible to increase the number of pages that can be printed by one printing unit U1, U2 as compared with the conventional case. As a result, multi-page printing equivalent to the conventional one can be realized with fewer printing units U1 and U2 than before, so that the printing apparatus or the printing press as a whole can be made compact. In this case, the maximum paper width equivalent to the conventional one is related to the approximate integer multiple of the vertical size of the broad format newspaper, so if an appropriate multiple is selected (for example, three times the vertical size of the broad format newspaper). It is also possible to use the web W having the maximum paper width as in the conventional case.

  In the newspaper offset rotary printing press according to the first embodiment, as the printing units U11 and U12, a plate cylinder 12 on which a printing plate is mounted and a blanket cylinder 13 for transferring ink of the plate cylinder 12 to the web W are provided. The circumference of the cylinder 12 is set to a size approximately n / 2 times the maximum paper width of the usable web W (n is a natural number). Accordingly, by setting the peripheral length of the plate cylinder 12 to be approximately n / 2 times the maximum paper width of the web W, the ratio between the peripheral length of the plate cylinder 12 and the maximum paper width is specified. A combination of the diameter and width of the plate cylinder 12 can be used. As a result, it is possible to prevent an increase in the size of the printing apparatus or an increase in the size of the entire printing apparatus or the printing press despite the multi-page correspondence. In other words, 1.5 times more pages can be printed on one web W than in the past. This can be converted into a reel of web, for example, 4 reels and 6 reels can be printed, so that the printing apparatus or the printing machine as a whole can be prevented from becoming large.

  In this case, n is preferably 1 or 2, and the size of the plate cylinder 12 can be optimized with respect to the printing units U11 and U12. That is, the printing units U1 and U2 that have been conventionally used as general-purpose machines are equipped with a so-called 4 plate that is capable of printing 1 page in the circumferential direction of the plate cylinder 12 and 4 pages in the longitudinal direction. A so-called 4 × 2 machine (2 × 1 machine (single cylinder machine with one page circumference), equipped with a printing plate capable of printing 2 pages in the circumferential direction of the plate cylinder 12 and 4 pages in the longitudinal direction. (A plate cylinder doubling machine with a page circumference), and printing on a single web W with more pages than before while optimizing the size of the plate cylinder 12 corresponding to the printing units U1 and U2. can do.

  When n = 1, it is possible to print a larger number of pages on one web W than the conventional one while optimizing the size of the plate cylinder 12 as corresponding to a 4 × 1 machine which is a general-purpose machine. it can. Conventionally, only 8 pages on the front and back sides can be printed, but 12 pages on the front and back sides can be printed. When n = 2, corresponding to 4 × 2 which is a general-purpose machine, conventionally, only one printing unit U1, U2 can print 16 pages on the front and back, but one printing unit U1, U2 A maximum of 24 pages can be printed. That is, more pages can be printed on one web W than before.

  Moreover, in the web offset press for newspapers of the first embodiment, a web pass device D is provided that vertically cuts the printed web W and then overlaps, and the folding machine F performs vertical folding that is vertically cut and stacked. A plurality of webs W that are not present are cut horizontally, folded horizontally, and then vertically folded to form the newspaper N. Therefore, similarly to the conventional printing press, the printed web can be vertically cut and stacked using the web pass device, and the printing device or the printing press as a whole can be simplified and reduced in cost. . In other words, compared to a conventional printing machine, when the same page is printed, the number of printing units can be reduced, and the printing apparatus or the printing machine as a whole can be reduced in size and cost. Also, a newspaper press is usually composed of a combination of single color printing units U1 and U2 and a color printing unit. In this case, when a newspaper is created, a color page is placed at a desired position. A bay window device is required. On the other hand, when the present invention is applied to a color printing unit, it is possible to increase the number of color pages. Therefore, it is possible to reduce the number of single color printing units and configure only a color printing unit. Become. In this case, it is not always necessary to provide a bay window device, and the web pass device can be simplified.

  In the printing method of the first embodiment, printing is performed on the web W so that the longitudinal direction of the broad-type newspaper is the conveyance direction of the web W. Accordingly, in the same way as described above, in one printing unit U11, U12, the web W having the same maximum paper width as the conventional one can be used, and the web W having the same paper width as the conventional one is almost the same size as the conventional one, and from the conventional one. Even different types of printed pages with many different images can be obtained. As a result, multi-page printing equivalent to the conventional one can be realized with fewer printing units U11 and U12 than before, and the entire printing apparatus or printing machine can be made compact.

  In the printing method according to the first embodiment, the printed web W is vertically cut and stacked, and the plurality of webs W that are not vertically folded are horizontally cut, horizontally folded, and then vertically folded. Produces a broad-format newspaper. Therefore, it is possible to easily print a broad-type newspaper.

  Then, by adjusting the circumference of the plate cylinder 12 to the size in the longitudinal direction of the broad newspaper, and setting the width of the plate cylinder to the size in the vertical direction of the broad newspaper, A broad-type newspaper can be formed with approximately the same size as before and more printed pages than before. As a result, the printing apparatus U or the entire printing machine can be made compact.

  Further, for example, the number of printing units can be reduced as compared with the conventional machine, and the printing apparatus or the entire printing machine can be made compact, so that the control when simultaneously printing different types of newspapers can be made simpler than before. it can.

  In each of the embodiments described above, the circumference of the plate cylinder 12 is set to be approximately an integral multiple of the size in the longitudinal direction of the broad newspaper, and the width of the plate cylinder 12 is set to the vertical length of the broad newspaper (printed material). Although set to a substantially integer multiple of the size in the direction, the multiple m of the substantially integer multiple is a natural number, and preferably m = 1 to 4, but is not limited to this value. Further, the circumference of the plate cylinder 12 is set to a size approximately n / 2 times the maximum paper width of the usable web W, and preferably n = 1 to 2, but is not limited to this value. Absent.

  Further, in each of the above-described embodiments, as shown in FIG. 3, when the circumferential length of the plate cylinder 12 is set to be approximately an integral multiple of the size in the longitudinal direction of the broad-format newspaper, a multiple m = 2 that is approximately an integral multiple. 6 types of printing plates 14a, 14b, 15a, 15b, 16a, 16b (or printing plates 14, 15, 16) with respect to the peripheral surface of the plate cylinder 12, and the vertical direction of the plate cylinder 12 is the axis of the plate cylinder 12. Although three are arranged in the axial direction of the plate cylinder 12 and two are arranged in the circumferential direction so as to be in the direction, the configuration is not limited to this. For example, when the circumferential length of the plate cylinder 12 is set to be approximately an integral multiple of the size in the longitudinal direction of a broad-format newspaper, a multiple m = 1 of approximately an integral multiple is set, and the plate cylinder 12 has three types relative to the circumferential surface. Three plate plates 14a, 15a, 16a (14b, 15b, 16b) may be attached side by side in the axial direction of the plate cylinder 12 so that the vertical direction is the axial direction of the plate cylinder 12. In this case, in each of the folding units 32, 71, 101, and 111, the folding cylinders 44 and 74 may be rotated twice to immediately discharge the sheets without overlapping the sheets.

  Further, in each of the above-described embodiments, the printed matter is described as a newspaper, but not limited to a newspaper, advertisements, free paper, and the like can be printed.

  Further, in each of the embodiments described above, the printing press of the present invention is a newspaper offset rotary printing press, but is not limited to this printing press, and can also be applied to a commercial offset rotary printing press. .
