Description

  The present invention relates to a printing machine having a plurality of printing units and a plurality of folding units, and a printing method using the printing machine.

  For example, a general web offset press for newspapers is composed of a plurality of paper feeding devices, a plurality of printing units, a turn bar device, and a folding machine, and a web is supplied from each paper feeding device to the printing unit. Then, after printing is performed on each web W, and the web is routed in the folding machine after being overlapped in a predetermined order after the travel routes of many webs are changed by the turn bar device. The paper is cut into a predetermined length and folded to form a folded book, which is discharged.

  Such a rotary offset printing press for newspapers is generally driven by a shaft driven type in which a line shaft is driven by a main drive motor and each printing unit or folding machine is driven through the line shaft while being synchronized. . However, in recent years, a so-called shaftless drive type has been proposed in which the operation elements such as each printing unit and folding machine are driven in synchronization with each other by individual motors instead of the line shaft.

  As a conventional shaftless drive type rotary printing press, for example, there is one described in Patent Document 1 below. The rotary printing machine described in Patent Document 1 includes a plurality of printing machines, a folding machine, a plurality of motors that drive the printing machine and the folding machine, a printing machine, a folding machine, and a control device that controls the motor. The control device has a plurality of drivers and a master station, and the master station generates virtual master axis data and a motor rotation command signal based on the position information of the folding machine and sends them to each driver. Synchronous operation control is performed.

  Further, a folding machine in a newspaper offset rotary printing press has two sets of folding units, for example, one described in Patent Document 2 below. In the folding machine described in Patent Document 2, folding units including a triangular plate, a lead-in roller, a nipping roller, a saw cylinder, a folding cylinder folding roller, an impeller, and the like are provided in parallel to the drag roller. Accordingly, the web printed from the printing unit is introduced into the folding machine after being overlapped in a predetermined order by the turn bar device. Then, the web is cut along the longitudinal direction while being guided by the drag roller, introduced into each folding unit, vertically folded by each triangular plate, and then sent to the folding cylinder by each roller. The web is cut off from the circumferential surface of the folding cylinder by the folding blade, and folded into a folded sheet by a pair of folding rollers. The folded sheet is sequentially received by the impeller. Are ejected.

  By the way, in general, newspapers have 40 pages (or 32 pages, 48 pages) in the morning edition and 20 pages (or 16 pages, 24 pages) in the evening edition. Therefore, when the morning newspaper (40 pages) is printed by the above-described newspaper offset rotary printing press, printing is performed on the web using a plurality of (5) printing units, and a number of web travel routes are generated by the turn bar device. After being changed, they are superimposed in a predetermined order and then introduced into the folding machine. A plurality of stacked webs are longitudinally cut while being guided by a drag roller, and then introduced together into one folding unit, vertically folded by a triangular plate, laterally cut by a saw cylinder, and horizontally by a folding cylinder and a folding roller. By folding, a 40-page signature can be formed.

  On the other hand, when printing the evening paper (20 pages) with this web offset press for newspapers, printing is performed on the web using multiple (5 units) printing units, and the travel route of many webs is changed by the turn bar device. After being overlapped in a predetermined order, they are introduced into the folding machine. A plurality of stacked webs are longitudinally cut while being guided by a drag roller, introduced into each folding unit, vertically folded by each triangular plate, laterally cut by a saw cylinder, and horizontally folded by a folding cylinder and a folding roller. As a result, a folding book of 20 pages can be formed in each folding unit, and the evening edition can be printed in half the time compared to the morning edition.

  In addition, as what arrange | positions the some triangular plate in the folding machine of a web offset printing press for newspapers shifting up and down or back and forth and right and left, there exists what was described in the following patent documents 3.

JP 2004-114705 A JP 2004-067357 A Japanese Patent Laid-Open No. 10-029387 Japanese Patent Laid-Open No. 11-035230

  By the way, the newspaper rotary offset printing press prints so-called reprints such as Saturday version, Sunday version, TV column for one week, advertisement, etc. in addition to the morning and evening editions. When such a separate print is printed by a newspaper offset rotary printing press, it is performed using a free time during which no morning or evening edition is printed. For this reason, the printing operation for separate printing by the rotary offset printing press is performed before and after the morning and evening printing work in consideration of the printing preparation time and the operation switching time. As a result, the work cost increases.

  In a conventional newspaper offset rotary printing press, the folding machine generally has two folding units, a driving side and an operation side. It is possible to print the evening paper with one folding unit and print another print with the other folding unit, but the material conditions for printing paper, etc., and the printing conditions such as the size and color combination of the patterns are different. Because of this, there is a case where it is desired to print the evening printing speed and the printing speed of the separate printing at different speeds, and it is difficult to print the evening printing and the separate printing at the same time with the conventional folding machine that drives the two folding units synchronously. . Further, in the conventional folding machine, since these two folding units are arranged adjacent to each other, when the evening web and the web for separate printing are conveyed in parallel, the webs having different conveyance speeds interfere with each other, and are damaged. There is a risk of it. In addition, although there are some which arrange a plurality of triangular plates in the folding machine up and down or back and forth and left and right (Patent Documents 3 and 4), because the folding cylinder is common, evening publications and different printings with different printing speeds can be printed simultaneously. I can't.

  In this case, the operation management control device 80 stores combinations of the printing units U1 to U6 and the folding units F1 and F2 and drive speeds V1 and V2 for the combinations as a plurality of print pattern IDs. By selecting a predetermined printing pattern ID using the management system operation panel 81, the printing units U1 to U6, the infeed devices I1 to I6, the turn bar device D, and the folding units F1 and F2 are selected based on the printing pattern ID. Can be controlled automatically.

  Specifically, for example, by storing (U1 + U2 + U3 + U4 + U5: F1: V1) as the print pattern ID 100, this print pattern ID 100 can be used as the morning print pattern ID. Further, by storing (U2 + U3 + U4: F1: V1) as the print pattern ID 101 or (U2 + U3 + U5: F1: V1) as the print pattern ID 102, the print pattern ID 101 and ID 102 can be used as the evening print pattern ID. it can. Further, by storing (U6: F2: V2) as the print pattern ID 103 or (U6: F2: V2) as the print pattern ID 104, it is possible to use the print pattern ID 103 and ID 104 as the pattern ID for reprint printing. it can.

  Here, the printing control in the newspaper offset rotary printing press according to the first embodiment will be specifically described.

  First, when a 40-page morning newspaper is printed using the newspaper offset rotary printing press of the first embodiment, the operator uses the operation management system operation panel 81 as shown in FIG. 1 to print pattern ID 100 (U1 + U2 + U3 + U4 + U5). : Select F1: V1) and enter. This print pattern ID 100 is a combination of the printing units U1, U2, U3, U4, U5 and the folding unit F1 and outputs a command for printing at a printing speed V1. Then, when the operation management control device 80 outputs this print pattern ID 100 to the control link, the corresponding controller, that is, the print unit controllers 71, 72, 73, 74, 75, the turn bar controller 77, and the folding unit controller 78 perform this printing. The pattern ID 100 is fetched. The printing unit controllers 71, 72, 73, 74, 75 control the driving speeds of the printing units U1, U2, U3, U4, U5 and the infeed devices I1, I2, I3, I4, I5 to V1, The folding unit controller 78 controls the driving speed of the folding unit F1 to V1, and the turn bar controller 77 changes the conveyance path of the web W sent from the printing units U1, U2, U3, U4, U5 to the folding unit F1. .

  Therefore, as shown in FIGS. 1 and 6, when the web W is supplied from the paper feeders R1 to R5 to the printing units U1 to U5, the printing units U1 to U5 have 4 for each web W. Color printing and two-color printing are performed. A large number of webs W that have been printed by the printing units U1 to U5 are subjected to vertical cutting by the turn bar device D, and then are superposed in a predetermined order while the conveyance path is changed. And in one folding unit F1 in the folding machine F, as shown in FIG. 2, after the web W introduced from the guide roller 51 is guided by the drag rollers 52a and 53a and vertically folded by the triangular plate 54a, The lead-in roller 55a, the nipping roller 56a, the guide roller 57a, and the nipping roller 58a are sent to the folding cylinder 59a.

  When the vertically folded web W reaches the folding cylinder 59a, the web W is paired from the folding cylinder 59a by being cut by a saw cylinder 60a at a predetermined position, and a folding blade protruding from the peripheral surface of the folding cylinder 59a. The folding book 61 is formed by being transferred to the folding roller 61a and being sandwiched between the folding rollers 61a. Then, the booklet S formed by the folding roller 61a is sequentially received by each blade of the impeller 62a and is transferred onto the paper discharge conveyor 63a. In this way, a 40-page morning newspaper can be printed.

  Next, when printing a 20-page evening edition using the newspaper offset rotary printing press of the first embodiment, the operator uses the operation management system operation panel 81 as shown in FIG. U2 + U3 + U4: F1: V1) is selected and input. This print pattern ID 101 is a combination of the printing units U2, U3, U4 and the folding unit F1, and outputs a command for printing at a printing speed V1. Then, when the operation management control device 80 outputs the print pattern ID 101 to the control link, the corresponding controller, that is, the print unit controllers 72, 73, 74, the turn bar controller 77, and the folding unit controller 78 capture the print pattern ID 101. . The printing unit controllers 72, 73, 74 control the driving speeds of the printing units U2, U3, U4 and the infeed devices I2, I3, I4 to VI, and the folding unit controller 78 is the driving speed of the folding unit F1. The turn bar controller 77 changes the conveyance path of the web W sent from the printing units U2, U3, U4 to the folding unit F1.

  Accordingly, as shown in FIGS. 1 and 7, when the web W is supplied from the paper feeders R2 to R4 to the printing units U2 to U4, each of the printing units U2 to U4 has 4 for each web W. Color printing and two-color printing are performed. A large number of webs W that have been printed by the printing units U2 to U4 are subjected to longitudinal cutting by the turn bar device D, and then are superposed in a predetermined order while the transport path is changed. And in one folding unit F1 in the folding machine F, as shown in FIG. 2, after the web W introduced from the guide roller 51 is guided by the drag rollers 52a and 53a and vertically folded by the triangular plate 54a, The lead-in roller 55a, the nipping roller 56a, the guide roller 57a, and the nipping roller 58a are sent to the folding cylinder 59a.

  When the vertically folded web W reaches the folding cylinder 59a, the web W is paired from the folding cylinder 59a by being cut by a saw cylinder 60a at a predetermined position, and a folding blade protruding from the peripheral surface of the folding cylinder 59a. The folding book 61 is formed by being transferred to the folding roller 61a and being sandwiched between the folding rollers 61a. Then, the booklet S formed by the folding roller 61a is sequentially received by each blade of the impeller 62a and is transferred onto the paper discharge conveyor 63a. In this way, a 20-page evening edition can be printed.

  Further, when printing the 20-page evening edition and the 8-page separate printing simultaneously using the newspaper offset rotary printing press of Example 1, the operator uses the operation panel 81 for the operation management system as shown in FIG. The print pattern ID 101 (U2 + U3 + U4: F1: V1) is selected and input, and the print pattern ID 103 (U6: F2: V2) is selected and input. This print pattern ID 103 is a combination of the print unit U6 and the folding unit F2 and outputs a command for printing at a printing speed V2. Then, when the operation management control device 80 outputs the print pattern ID 101, ID 103 to the control link, the corresponding controller, that is, the print unit controllers 72, 73, 74, the turn bar controller 77, and the folding unit controller 78, print pattern ID 101. The print unit controller 76, the turn bar controller 77, and the folding unit controller 79 capture the print pattern ID 103. The printing unit controllers 72, 73, and 74 control the driving speeds of the printing units U2, U3, U4 and the infeed devices I2, I3, and I4 to V1, and the folding unit controller 78 sets the driving speed of the folding unit F1. Control to V1.

  The printing unit controller 76 controls the driving speed of the printing unit U6 and the infeed device I6 to V2, and the folding unit controller 79 controls the driving speed of the folding unit F2 to V2. Then, the turn bar controller 77 changes the conveyance path of the web W sent from the printing units U2, U3, U4 to the folding unit F1, and changes the conveyance path of the web W sent from the printing unit U6 to the folding unit F2. To do.

  Accordingly, as shown in FIGS. 1 and 7, when the web W is supplied from the paper feeders R2 to R4 to the printing units U2 to U4, each of the printing units U2 to U4 has 4 for each web W. Color printing and two-color printing are performed. When the web W is supplied from the paper supply device R6 to the printing unit U6, four-color printing is performed on the web W in the printing unit U6. A large number of webs W printed by the printing units U2 to U4 and U6 are subjected to longitudinal cutting by the turn bar device D, and then are superposed in a predetermined order while the conveyance path is changed. As shown in FIG. 2, the web W printed by the printing units U2 to U4 is introduced into one folding unit F1 in the folding machine F, guided by the drag rollers 52a and 53a, and vertically folded by the triangular plate 54a. Is applied to the folding drum 59a by the lead-in roller 55a, the nipping roller 56a, the guide roller 57a, and the nipping roller 58a. On the other hand, a large number of webs W printed by the printing unit U6 are introduced into the other folding unit F2 in the folding machine F, guided by the drag rollers 52b and 53b, and vertically folded by the triangular plate 54b. The in-roller 55b, the nipping roller 56b, the guide roller 57b, and the nipping roller 58b are fed to the folding cylinder 59ba.

  At this time, in this embodiment, in each of the folding units F1 and F2 of the folding machine F, the adjacent drag rollers 52a and 53a and the drag rollers 52b and 53b are vertically displaced and the adjacent triangular plates 54a and 54b are vertically moved. It is shifted and arranged. Therefore, the web W that is printed by the printing units U2 to U4 and introduced into the folding unit F1 and the web W that is printed by the printing unit U6 and introduced into the folding unit F2 are transport speeds V1, Although V2 is different, when the web W is guided by the drag rollers 52a, 52b, 53a, 53b and vertically folded by the triangular plates 54a, 54b, the position of each moving web W is shifted up and down, and both webs W come into contact with each other. Nevertheless, damage due to this contact is suppressed.

  Thereafter, when the vertically folded web W reaches the folding cylinders 59a and 59b in the folding units F1 and F2, the saw cylinders 60a and 60b are transversely cut at predetermined positions, and the peripheral surfaces of the folding cylinders 59a and 59b When the folding blade protrudes from the folding rollers 59a and 59b, the web W is transferred to the pair of folding rollers 61a and 61b, and the folded paper S is formed by being sandwiched between the folding rollers 61a and 61b. Then, the booklet S formed by the folding rollers 61a and 61b is sequentially received by the blades of the impellers 62a and 62b, and is transferred onto the paper discharge conveyors 63a and 63b. In this way, the 20-page evening print and the 8-page reprint can be printed at the same time and at different speeds.

  Even in the newspaper offset rotary printing press of this embodiment, printing is performed using five printing units U1 to U5, and two folding units F1 and F2 are used, as in the conventional printing press. 20 pages each can be formed, and the evening edition can be printed in half the time of the morning edition.

  As described above, in the printing press and printing method according to the first embodiment, the drive motors 17 to 22 of the printing units U1 to U6 can be driven and controlled by the printing unit controllers 71 to 76 in the newspaper offset rotary printing press. The turn bar device D that changes the vertical cutting of the web W and the conveyance path can be driven and controlled by the turn bar controller 77, and the drive motors 41, 42, 45, 46 of the folding units F 1, F 2 in the folding machine F are folded unit controller 78. , 79 can be driven and controlled, and all the controllers 71 to 79 can be controlled by the operation management control device 80, and an operation command can be input to the operation management control device 80 using the operation management system operation panel 81. .

  Therefore, the operator uses the operation management system operation panel 81 to the operation management control device 80 using the combination of the printing units U1 to U6 and the folding units F1 and F2 and the printing speed (driving speed) as an operation command. When input, the operation management control device 80, based on this operation command, the combination of the printing units U1 to U6 and the folding units F1 and F2, that is, from the printing units U1 to U6 by the turn bar device D to the folding units F1, F1. Since the sending path to F2 is set, the driving speeds of the printing units U1 to U6, the infeed devices I1 to I6, and the folding units F1 and F2 are set, and each unit combined is driven independently. Each unit can print different types of printed matter at different printing speeds at the same time. It is possible to improve, it is possible to reduce the operating costs by reducing paper loss by shortening the print preparation time. Further, different types of printed matter can be simultaneously printed at different printing speeds by one folding machine F having the folding units F1 and F2. In addition, it is not necessary to arrange the triangular plate portions of the two folding machines F in multiple stages, there is no need to increase the size of the device and the height of the building, and it is easy to replace the printing machine in an existing building. It can correspond to.

  In this case, the operation management control device 80 stores combinations of the printing units U1 to U6 and the folding units F1 and F2 and the driving speeds V1 and V2 for the combinations as a plurality of print pattern IDs. By selecting a predetermined printing pattern ID using the operation panel 81, the printing units U1 to U6, the infeed devices I1 to I6, the turn bar device D, and the folding units F1 and F2 are automatically selected based on the printing pattern ID. I try to control it.

  Accordingly, the operator simply selects the print pattern ID from the operation management system operation panel 81, and the combinations of the print units U1 to U6 and the folding units F1 and F2 and the folding units U1 to U6 are folded based on the print pattern ID. The sending path to the units F1 and F2 and the driving speed for each unit combined are automatically set, and the operability can be improved.

  Further, a turn bar device D is provided for setting a delivery path from each printing unit U1 to U6 to each folding unit F1, F2, and the operation management control device 80 is based on an operation command of the operation management system operation panel 81. D is controlled, and the delivery path from the printing units U1 to U6 to the folding units F1 and F2 in each unit combined is automatically set, and operability can be improved.

  In the printing machine of the present embodiment, the adjacent drag rollers 52a and 53a and the drag rollers 52b and 53b are shifted up and down in the folding units F1 and F2 of the folding machine F, and the adjacent triangular plates 54a and 54b are arranged. They are shifted up and down. Therefore, the conveyance speed of the web W that is printed in the printing units U2 to U4 and introduced into the folding unit F1 is different from the conveyance speed of the web W that is printed in the printing unit U6 and introduced into the folding unit F2. Even so, when guided by the drag rollers 52a, 52b, 53a, 53b and vertically folded by the triangular plates 54a, 54b, the position of each moving web W will be shifted up and down, and the two webs W will contact each other. No, interference between the webs W is suppressed, and damage to the webs W can be prevented.

  In this case, in each of the folding units F1 and F2 of the folding machine F, the lower end portions of the adjacent triangular plates 54a and 54b are arranged at the same position in the width direction of the vertically folded folded book S. Accordingly, the folded book S vertically folded by the adjacent triangular plates 54a and 54b is sent to substantially the same position in the width direction, and the folding cylinders 59a and 59b and the saws in the plurality of folding units F1 and F2. The arrangement of the drums 61a and 61b, the impellers 62a and 62b, and the paper discharge conveyors 63a and 63b can be simplified.

  In this embodiment, the folding machine F including the two folding units F1 and F2 is installed on the third floor of the building, and the drag roller 52a in one folding unit F1 with respect to the floor surface G of the third floor. 53a, the triangular plate 54a, the lead-in roller 55a, and the drag rollers 52b, 53b, the triangular plate 54b, and the lead-in roller 55b in the other folding unit F2 are vertically displaced. Therefore, at least the drag rollers 52a, 52b, 53a, 53b and the triangular plates 54a, 54b of the two folding units F1, F2 adjacent to one and the same floor are arranged, and the triangular plates 54a, 54b are shifted up and down. In the limited building, the folding machine F can be efficiently arranged without expanding the installation space, and at least the drag rollers 52a, 52b, 53a, 53b of the two adjacent folding units F1, F2 and Since the triangular plates 54a and 54b are on the same floor, various operations such as operation and maintenance by the operator such as a paper threading operation and an adjustment operation of the triangular plates 54a and 54b can be easily performed, and workability can be improved. .
