Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an automatic plate hanging display device for a printing unit such as a newspaper rotary press.

[Prior Art] FIG. 3 is a diagram showing a sheet path centered on the printing unit of a newspaper rotary press, in which the running paper 2 mounted on the reel stand 1 passes through each guide roller 3 and dancer roller 4. The running paper 2 is sent to a printing unit 5 for printing, and the running paper 2 that has passed through this printing unit 5 advances to an intermediate drag 7. Four printing plates (not shown) are attached to the cylinder of the printing unit 5, and these printing plates have, for example, two page circumference x one page width (1098.8 mm x 400 mm). Each printing plate has a different paper surface attached to it, and each printing plate has two plates of the same paper surface (one half circle each).
Installed.

FIG. 2 shows the concept in which printing plates are assigned to the printing unit 5. The three groups in FIG. 2 represent respective printing units, each printing unit representing a left-hand plate cylinder and a right-hand plate cylinder in simultaneous duplex printing. The numbers on each plate cylinder indicate the page, indicating that four paper plates are attached to one plate cylinder. The frame-filled version indicates the next version (the version with revised content).

In the structure described above, it is important to allocate which page of the newspaper is to be printed at which location in the printing unit 5, and this is generally called printing. This plate loading is automatically determined once the operating conditions (unit used, number of pages, color pages, etc.) are determined.

[Problems to be solved by the invention] Conventionally, the most efficient pattern was determined based on the above operating conditions and the experience of an expert, and the data was written on a blackboard etc. and the printing process was carried out by writing the data on a blackboard etc. was instructing the person. If there is a request for a plate change, it is complicated to rewrite the data on the blackboard each time, so there is a strong desire to develop a device that can quickly perform plate printing.

The object of the present invention is to provide an automatic plate hanging display device that can satisfy this demand.

[Means for Solving the Problems] In order to achieve the above object, the present invention is constructed as follows. In other words, the unit used for the printing plate of a printing unit such as a newspaper rotary press, the number of pages,
A data input device that can input operating conditions for determining plate loading for color pages, etc.; and a data input device that inputs the above operating conditions to the printing plate of the printing unit, and inputs the number of pages to the printing unit. a central computer that performs calculations for allocation; a first communication control device that converts page number allocation information from the central computer from parallel signals to serial signals;
A second communication control device on the printing unit side receives a serial signal from a communication control device via a transmission path, and converts the serial signal into a parallel signal. It consists of a local computer that processes and obtains printing information, and a printing display device that displays the printing information of this local computer via a latch device that latches it.

[Operation] With the configuration as described above, when the operating conditions of the printing unit are input to the central computer, calculations for allocating the number of pages to the printing unit are performed. The result of this calculation is displayed on the printing plate display device. Therefore, there is no need for handwritten display on a conventional blackboard or the like.

[Example] Hereinafter, an example of the present invention will be described with reference to the drawings. FIG. 1 is a diagram showing the configuration of the plate hanging display device. A central computer room 10 is provided far away from the rotary press, and within this central computer room 10, a central computer 11, a display device 12, a data input device 13, and a first communication control device 14 are installed.

Also, the plate display devices 18 ₁ , 18 ₂ , 18 ₃ on the printing unit 5 side of the rotary press are connected to second communication control devices 15 ₁ , 15 ₂ , for receiving data sent from the central computer room 10 . 15 ₃ , local computer 1
7 ₁ , 17 ₂ , 17 ₃ , latch device 1 for data storage
9 ₂ and a printing plate display device 20 ₂ . The plate hanging display devices 18 ₁ , 18 ₂ , 18 ₃ are installed corresponding to each printing unit 5 .

The data input device 13 is capable of inputting operating conditions for a printing plate of a printing unit such as a newspaper rotary press. The central computer 11 inputs operating conditions for the printing plates of the printing units from the data input device 13 and performs calculations for allocating page numbers to the printing units. The first communication control device 14 converts the page number allocation information from the central computer 11 from a parallel signal to a serial signal.

The second communication control devices 15 ₁ , 15 ₂ , 15 ₃ are supplied with serial signals from the first communication control device via the communication cable 16, and convert the serial signals into parallel signals. The local computers 17 ₁ , 17 ₂ , 17 ₃ process the parallel signals from the second communication control devices 15 ₁ , 15 ₂ , 15 ₃ to obtain printing information. Both printing plate display devices 20 ₂ are connected to the local computer 1 mentioned above.
The printing information of 7 ₁ , 17 ₂ , and 17 ₃ is displayed via a latch device 19 ₂ that latches each of them.

With the above configuration, the operator can specify the operating conditions (unit used, number of pages, color pages, etc.)
By inputting the information from the data input device 13, the central computer 11 performs calculations for allocating the number of pages to each printing unit 5, and this information is converted from a parallel signal to a serial signal by the communication control device 14, and then sent to the communication cable. A plate hanging display device 18 attached to the machine of each printing unit via 16
₁ , 18 ₂ , 18 ₃ communication control device 15 ₁ , 15 ₂ , 1
5 Transmitted to ₃ . Here, the serial signal is converted to a parallel signal and each display device 18 ₁ , 18 ₂ , 18
₃ is transmitted via the address bus 21, data bus 22 and latch ₁₉₂ , respectively. The results are displayed on the printing plate display device ₂₀₂ as shown in FIG.

Based on the printing plate display information actually shown in FIG. 2, the operator can easily attach the corresponding printing plate to the cylinder of the printing unit 5.

[Effects of the invention] The invention described above is constructed as follows. That is, a data input device capable of inputting operating conditions for determining the printing plate of a printing unit such as a newspaper rotary press, the number of pages, color pages, etc. to be used, and printing from this data input device. Input the above operating conditions for the printing plate of the unit,
a central computer that performs calculations for allocating page numbers to the printing units; a first communication control device that converts page number allocation information from the central computer from parallel signals to serial signals; A second communication control device on the printing unit side converts the serial signal into a parallel signal, and processes the parallel signal of the second communication control device to perform printing. It consists of a local computer that obtains information and a printing plate display device that displays plate setting information from this local computer via a latch device.

With this structure, what was previously processed in the head of an expert can be used on a computer, and that information can be displayed in a convenient location for mechanical work, making it possible to speed up the printing process. It is possible to provide an automatic plate loading display device that increases the operating rate of the unit.
