Then, when the operation management control device 35 outputs this print pattern ID 102 to the control link, the corresponding paper feed controllers 22, 23, print controllers 27, 28, web path controller 31, and folding controller 34 capture the print pattern ID 102. . The controllers 22, 23, 27, 28, 31, and 34 control the driving speeds of the paper feed units R2 and R3, the printing units U21 and U22, the web pass unit D1, and the folding unit F2 to V2, and the web W The conveyance path is changed to the folding unit F2.

  Therefore, as shown in FIG. 11, when the web W is supplied from the paper feeding devices R2 and R3 to the printing units U2 (U21 and U22), the printing units U21 and U22 have 2 for each web W. Color printing is performed. The two webs W printed by the printing units U21 and U22 are overlapped in a predetermined order while the conveyance path is changed after the longitudinal cutting is performed in the web pass unit D1. There are four webs W. In the folding unit F2, as shown in FIG. 6, the web W is vertically folded by the triangular plate 201b, and then sent to the second folding mechanism 204 by the lead-in rollers 202a and 202b and the nipping rollers 203a and 203b. It is done.

  In the second folding mechanism 204, when the vertically folded web W reaches the folding cylinder 211, it is cut horizontally by the saw cylinder 212 at a predetermined position, and the folding blade protrudes from the peripheral surface of the folding cylinder 211. The web W is transferred from the folding cylinder 211 to the pair of folding rollers 213a and 213b, and is sandwiched between the folding rollers 213a and 213b to form a fold. Then, the signatures formed by the folding rollers 213a and 213b are sequentially received by each blade of the second impeller 205 and transferred onto the paper discharge conveyor 206. In this way, four sheets and 16 pages of newspaper B can be printed.

  In this case, the operator can use many combinations of units by using the operation management system operation panel 36 depending on the number of newspaper pages to be printed, and is not limited to those described in the embodiments. For example, as shown in FIG. 12, the operator selects and inputs the print pattern ID 201 (R1 + R3 + U11 + U12 + U21 + D1 + F2: V1) using the operation management system operation panel 36. The print pattern ID 201 sets a combination unit that combines the paper feed units R1, R3, the print units U11, U12, U21, the web pass unit D1, and the folding unit F2, and outputs a command to perform printing at the print speed V1. Is. The operator selects and inputs a print pattern ID 202 (R2 + R4 + U22 + U31 + U32 + D1 + D2 + F1: V2) using the operation management system operation panel 36. The print pattern ID 202 is a command for setting a combination unit combining the paper feed units R2 and R4, the print units U22, U31, and U32, the web pass units D1 and D2, and the folding unit F1, and performing printing at the print speed V2. Output.

  In the above description, a mode has been described in which two types of newspapers A and B are simultaneously printed by the newspaper offset rotary printing press of the present embodiment. However, only one type of newspaper having multiple pages is provided as in the prior art. Can also be printed.

  That is, the operator inputs, for example, the print pattern ID 100 using the operation management system operation panel 36. The print pattern ID 100 is (R1 + R2 + R3 + R4 + U11 + U12 + U21, U22 + U31 + U32 + D1 + D2 + F1 + F2: V1), and is a newspaper C print pattern ID. The print pattern ID 100 is a command that sets a combination unit that combines the paper feed units R1 to R4, the print units U11 to U32, the web pass units D1 and D2, and the folding units F1 and F2, and performs printing at the printing speed V1. Output. Then, when the operation management control device 35 outputs the print pattern ID 100 to the control link, the corresponding paper feed controllers 21 to 24, print controllers 25 to 30, web path controllers 31 and 32, and folding controllers 33 and 34 perform this printing. The pattern ID 100 is fetched. Each of the controllers 21 to 34 controls the driving speeds of the paper feeding units R1 to R4, the printing units U11 to U32, the web path units D1 and D2, and the folding units F1 and F2 to V1, and the web W conveyance path is folded. Change to both units F1 and F2.

  Therefore, as shown in FIG. 11, when the web W is supplied from the paper feeders R <b> 1 to R <b> 4 to the printing units U <b> 11 to U <b> 32, each of the printing units U <b> 11 to U <b> 32 performs two-color printing and 4 printing. Color printing is performed. The four webs W printed by the printing units U11 to U32 are overlapped in a predetermined order while the conveyance path is changed after the longitudinal cutting is performed by the web pass units D1 and D2. Thus, there are 8 webs W. Then, after folding in the folding units F1 and F2, the sheet is cut horizontally, and folded horizontally to form a fold, and then discharged. In this manner, eight 32 pages of newspaper C can be printed.

  In this case, the usage of the folding units F1, F2 can be selected according to the number of newspapers. For example, a double-out process using the triangular plates 201a and 201b and the first and second folding mechanisms 107 and 204, the triangular plate 201a (or the triangular plate 201b) and the first folding mechanism 107 (or the second folding mechanism 204). , A transfer process using the triangular plate 201a (or the triangular plate 201b) and the first and second folding mechanisms 107, 204, a triangular plate 201a, 201b and the first folding mechanism 107 (or the second folding mechanism). There is a sectioning process using the tatami mechanism 204). Either process can be selected according to the number and form of newspaper C pages and the printing speed.

  The number of newspapers A and B, two-color printing (single-color printing), depending on how the printing units U1 to U3 are used, that is, whether the four-color printing is performed integrally or the two-color printing is performed separately. Alternatively, four-color printing can be set. In this embodiment, three printing units capable of four-color printing are arranged. However, the present invention is not limited to this configuration, and four or more printing units capable of four-color printing are arranged, or two-color printing is performed. A unit and a four-color printing unit may be combined.

  In the newspaper offset rotary printing press of this embodiment, the printing units U1 to U3 have drive motors that can drive the plate cylinders 12 and the blanket cylinders 13 independently. In the web pass units D1 and D2, the slitter S1, the turn bar T1, and the compensator C1 corresponding to each web W to be conveyed have drive motors that can be individually driven. Therefore, the printing units U1 to U3 can independently drive the upper printing units U11, U21, and U31 and the lower printing units U12, U22, and U32, and the upper and lower plate cylinders 12 in each of the printing units U11 to U32. The blanket cylinder 13 can be driven independently. In addition, the slitter S1, the turn bar T1, and the compensator C1 of the web pass units D1 and D2 can drive the mechanisms stacked one above the other independently.

  By the way, as described above, the rotary offset printing press for newspapers of this embodiment can print one type of newspaper and can simultaneously print two types of newspapers. When printing, there are the following problems. That is, when two types of newspapers are printed at the same time, the newspapers often differ in the number of copies, printing time, printing speed, and the like. For this reason, one web and the other web may interfere with each other during the conveyance process in which the web is processed by the folding machine from the printing unit and discharged, which adversely affects the safety and print quality of the printing operation. There is a fear.

  For example, during the printing operation of one newspaper, it is necessary to prepare for printing the other newspaper, that is, to perform a paper threading operation for passing the web through the conveyance path. There is a possibility of contact with the web being conveyed. Moreover, when two types of newspapers are printed simultaneously, since the conveyance speeds of the newspapers are different, an unexpected air flow occurs between them, which may adversely affect the conveyance of the web. Furthermore, the newspaper rotary offset printing press is provided with a safety device, and the printing press stops due to the operator entering the safety zone during the printing operation. In this case, when maintenance is performed on the unit that prints one of the newspapers, all the units are stopped, and when the safety device is disabled, the safety of the operator cannot be ensured.

  Therefore, in order to solve this problem, in the newspaper rotary offset press of this embodiment, when two types of newspapers are printed at the same time, the paper feeding units R1 to R4, the printing units U1 to U3, and the web pass units D1 and D2 are used. When a predetermined two combination units are set from the folding units F1 and F2, a partition member is provided for preventing interference between the web conveyed by one combination unit and the web conveyed by the other combination unit.

The safety covers 74 and 75 include upper detachable covers 77 and 78 facing the folding mechanisms (folding portions) 107 and 204 in the folding units F1 and F2, and a paper discharge conveyor (discharge) in the folding units F1 and F2. And lower slide covers 79 and 80 facing the paper portions 109 and 206.

  Hereinafter, the safety covers 74 and 75 will be described, but since both have substantially the same configuration, only one safety cover 74 will be described.

  In the safety cover 74, as shown in FIG. 8, mounting brackets 81a and 81b are fixed to both side portions (partition walls 71 and 73a), and an upper detachable cover 77 is disposed on the upper portions of the mounting brackets 81a and 81b. And fixed by a plurality of fixing bolts (not shown). In addition, guide rails 82a and 82b extending in the vertical direction are fixed to lower portions of the mounting brackets 81a and 81b, and a lower slide cover 79 is supported along the guide rails 82a and 82b so as to be movable up and down. In this case, the lower slide cover 79 is arranged to be displaced in the thickness direction with respect to the upper detachable cover 77, and when the lower slide cover 79 is lifted, it overlaps with the upper detachable cover 77 in the thickness direction. The lower part can be released. Further, both the covers 77 and 79 can be removed at a position where the lower slide cover 79 overlaps the upper removable cover 77.

  That is, as shown in FIGS. 8 and 9, the lower slide cover 79 has guide rollers 83a and 83b rotatably mounted at the upper and lower positions at the left and right ends, and the guide rollers 83a and 83b are It fits on the guide rails 82a and 82b, and is freely rollable. As shown in FIGS. 8 and 10, the mounting brackets 81a and 81b have locking holes 84a and 84b formed in the guide rails 82a and 82b. On the other hand, in the lower slide cover 79, locking claws 85a and 85b are attached to the left and right end portions so as to be movable in the horizontal direction, and the locking claws 85a and 85b are connected to the operation handle 87 via the connecting rods 86a and 86b. It is connected to. Further, the lower slide cover 79 is connected to the winding drums 89a and 89b via a pair of left and right connecting chains 88a and 88b. Winding springs (not shown) are provided in the winding drums 89a and 89b, and the lower slide cover 79 is biased and supported upward via connecting chains 88a and 88b.

  Each safety cover 74, 75 is provided with detection switches (detectors) 91, 92 for detecting the open / closed state (open state) of the lower slide covers 79, 80, and the detection result is an operation management control device. 35 can be input. When the operation management control device 35 sets two combination units and performs drive control respectively, according to the detection results of the detection switches 91 and 92, the sheet feeding units R1 to R4 and the printing units U1 to U3 (U11). To U32) and the corresponding unit among the folding units F1 and F2 can be stopped. In this case, the detection switch 91 corresponds to the lower slide cover 79 of the folding unit F1, and the detection switch 92 corresponds to the lower slide cover 80 of the folding unit F2.

  That is, for example, as described above, the operation management control device 35 stores (R1 + R4 + U11 + U11 + U31 + U32 + D1 + D2 + F1: V1) as the print pattern ID 101 and stores (R2 + R3 + U21 + U22 + D1 + F2: V2) as the print pattern ID 102. At this time, when the detection switch 91 detects the open state of the lower slide cover 79 (ON), the operation management control device 35 selects the paper feeding units R1 and R4 selected by the printing pattern ID 101 and the printing units U11 and U12. , U31, U32, the web pass units D1, D2, and the folding unit F1 are stopped. On the other hand, when the detection switch 92 detects the open state of the lower slide cover 80 (ON), the operation management control device 35 selects the paper feed units R2 and R3 selected by the print pattern ID 102 and the print units U21 and U22. The driving of the web pass unit D1 and the folding unit F2 is stopped.

  Specifically, when the operator selects and inputs the print pattern ID 101 and the print pattern ID 102 using the operation management system operation panel 36, two combination units are set. Then, the operation management control device 35 outputs the print patterns ID 101 and ID 102 to the control link, and supplies the paper feed controllers 21 to 24, the print controllers 25 to 30, the web path controllers 31 and 32, the folding controllers 33, 34 captures the print pattern ID 101 and drives and controls the paper feed units R1 to R4, the print units U11 to U32, the web pass units D1 and D2, and the folding units F1 and F2, and prints two types of newspapers. .

  At this time, when the detection switch 91 detects the opening of the lower slide cover 79, the operation management control device 35 outputs (R1 + R4 + U11 + U12 + U31 + U32 + D1 + D2 + F1: V0) as the print pattern ID 101 to the control link based on the opening signal from the detection switch 91. The drive of the selected paper feeding units R1, R4, printing units U11, U12, U31, U32, web pass units D1 (partly), D2, and folding unit F1 is stopped. In this case, V0 is a stop signal. On the other hand, even when the detection switch 92 detects the opening of the lower slide cover 80, the operation management control device 35 similarly controls the print pattern ID 102 by adding a stop signal V 0 based on the release signal from the detection switch 92. Outputs to the link and stops driving each selected unit.

  Note that the operation management control device 35 stopping the driving of each unit stops the supply of power to each unit. When the detection switch 91 detects the opening of the lower slide cover 79, the operation management control device 35 stops driving the web path units D1 and D2. In this case, the web path set by the print pattern ID 101 is used. The driving of a part of the unit D1 is stopped.

  In addition, in the newspaper rotary offset press of this embodiment, two types of newspapers can be printed at the same time, but only one type of newspaper with multiple pages can be printed. That is, the operator inputs (R1 + R2 + R3 + R4 + U11 + U12 + U21, U22 + U31 + U32 + D1 + D2 + F1 + F2: V1) as the print pattern ID 100 to the operation management control device 35. Then, the operation management control device 35 outputs the print pattern ID 100 to the control link, and the corresponding paper feed controllers 21 to 24, print controllers 25 to 30, web path controllers 31 and 32, and folding controllers 33 and 34, According to the printing pattern ID 100, the paper feeding units R1 to R4, the printing units U11 to U32, the web path units D1 and D2, and the folding units F1 and F2 are driven and controlled to print one type of newspaper.

  At this time, when one of the detection switches 91 or 92 detects the opening of the lower slide cover 79 or 80, the operation management control device 35 uses the opening signal from the detection switches 91 and 92 as the print pattern ID 100 ( R1 + R2 + R3 + R4 + U11 + U12 + U21, U22 + U31 + U32 + U41 + U42 + D1 + D2 + F1 + F2: V0) is output to the control link, and the selected paper feeding units R1 to R4, printing units U11 to U32, web path units D1 and D2, and folding units F1 and F2 are stopped. .

  In this case, all the units are in the stopped state, but among the units, the unused units are already in the stopped state, so there is no need to output a stop signal.

  Therefore, as shown in FIG. 13, when the web W1 is processed on the folding unit F1, the web W2 is processed on the folding unit F2, and two kinds of newspapers are printed, the safety covers 74 and 75 cause the web W1 Intrusion to the folding unit F2 side and web W2 to the folding unit F1 side are prevented. At this time, when the detection switch 91 detects the opening of the lower slide cover 79, the operation management control device 35 stops the processing of the web W1 by stopping the driving of the corresponding unit. On the other hand, when the detection switch 92 detects the opening of the lower slide cover 80, the operation management control device 35 stops the processing of the web W2 by stopping the driving of the corresponding unit.

  Further, as shown in FIG. 14, when the web W is processed by the folding units F1 and F2 and one kind of newspaper is printed (so-called double-sided printing), the safety covers 74 and 75 interfere with each web W. Is prevented. At this time, when the detection switch 91 detects the opening of the lower slide cover 79, the operation management control device 35 stops the processing of the web W by stopping the driving of all units. Further, when the detection switch 92 detects the opening of the lower slide cover 80, the operation management control device 35 similarly stops the processing of the web W by stopping the driving of all units.

  Further, as shown in FIG. 15, when the folding unit F1 is stopped, the web W is processed by the folding unit F2, and one kind of newspaper is printed (so-called one-side printing), the detection switch 91 is moved downward.
