Abstract

PURPOSE:To enable pressplates to be full-automatically made and carried by the required number in a minimum time, by a method wherein, during the process with one process machine, the process of the same paper face is carried out with another process machine, and the remaining number of the required number for the paper face is redistributed to the respective process machines. CONSTITUTION:A plurality of process machines 10 and a plurality of unloading portions 13 are connected by lines of a plurality of conveyers 12. The lines between loading portions 11 and the conveyers 12 are so constructed as to allow the carrying to an arbitrary one of the unloading portions 13 from any of the process machines 10. In a fill automatic redistribution, such a requirement of redistribution as that the same paper face is under process with another process machine is judged at the receiving of a process start. If the requirement is met, the pressplates of the same quality are used by the same set, whereby the predetermined number of pressplates and experience for every unloading portion 13 are stored, and the pressplates are redistributed by the predetermined number for every unloading portion 13 so as to be equal in each process machine. In this manner, the full automatic process of the same paper face can be conducted by using a plurality of process machines, thus enabling pressplates to be made and carried by the required number with a minimum time.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a printing plate making machine and a printing plate transport device used in newspaper production, and particularly to printing plates that require a fully automatic plate making machine and a lightweight printing plate transport device. The present invention relates to a fully automatic plate making and conveying device suitable for the process.

[Conventional technology]

``Newspaper Production and Electronics'' (Japan Newspaper Association) describes printing plate making machines and printing plate transport devices.

There is no particular mention of making the required number of sheets for a certain sheet of paper using a single plate-making machine, but since plates of the same quality are set on the same rotary press, had to be made using a single plate-making machine.

[Problem that the invention seeks to solve]

The above conventional technology automates newspaper production by implementing CTS conversion, deleading, etc., but does not take into consideration the ability to respond to sudden events such as accidents and redoing. In such cases, there is a problem in that it must be handled manually or semi-automatically.

The purpose of the present invention is to connect the plate-making section and the conveyance section in newspaper production, especially in the printing plate process, and to use multiple plate-making machines to fully automatically make and convey the required number of printing plates in the minimum amount of time. It is to do so.

[Means for solving problems]

The above purpose is to make a plate of the same paper on another plate-making machine while making a plate with one plate-making machine, and to transfer the remaining number of required sheets of that paper (planned number of plates to be made) to each plate-making machine. This is achieved through reallocation.

As shown in FIG. 3, the layout of the printing plate process includes a plurality of plate making machines 10, a plurality of unloading sections 13, and a plurality of conveyors 12.
A line between the loading section 11 and the conveyor is configured so that the material can be transported from any plate making machine to any unloading section.

Here, the line of the conveyor corresponds to the line of the rotary press, and the set of the rotary press and folding section is one-to-one with the unloading section.

Under the current equipment conditions, the plate-making capacity of the plate-making machine (one machine can produce one printing plate)
The speed at which sheets are made into plates is considerably lower than the conveyance speed of the conveyor, so it can be said that using a predetermined machine from the plate making stage to make the required number of sheets as quickly as possible.

[Effect]

Figure 1 shows a fully automatic plate making and conveying device. First, the control unit 1 calculates the required number of sheets for each page based on printing plate information 4 consisting of page information and print layout information.

Next, the plate-making unit 2 recognizes the paper surface and the plate-making machine that started plate-making by the plate-making start 5, and calculates the required number of sheets for the paper surface.
Indicate as the number of plates made by the applicable plate making machine. At this time, the information that plate making has been started is stored sequentially, and when the printing plate arrives at the loading section from the conveyance section 3, and when the conveyance destination request 7 is received,
This is a method in which a transport destination instruction 8 is given to an unloading section (transport destination) for a printing plate whose plate making has already started.

In the case of fully automatic redistribution, at the time of receiving plate-making start 5,
The unloading section ( Transfer destination) Plates that are being processed in a child process with a different number of plates should already be allocated to the plate making department. Furthermore, since the plate making of the same sheet of paper does not end during the redistribution process, it is important to determine the lower limit value c1 of the redistribution result.

〔Example〕

FIG. 2 shows a flowchart of the redistribution logic of the control section of the fully automatic plate making and conveying apparatus according to the embodiment of the present invention.

According to this embodiment, it is possible to fully automatically transport printing plates of the same paper surface using a plurality of plate-making machines, which has the effect of shortening the printing plate process.

In addition, the redistribution logic when a plate-making machine breaks down while printing plates for the same paper is being made by multiple plate-making machines is almost the same as the redistribution logic shown in the example, and the planned amount of the failed machine is allocated. By redistributing the paper to another plate-making machine, it is possible to make and transport the corresponding paper surface without the need for operating operations.

As explained above, according to the present invention, it is possible to respond fully automatically to unexpected events, and there are also effects such as ease of operation, labor saving for the operator, and safety.

[4 Effects of the invention] -'According to the present invention, it is possible to fully automatically make plates for the same sheet of paper using multiple plate making machines, so it is possible to make and transport the required number of printing plates in the minimum amount of time. effective.
