Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is used in newspaper printing to convey a printing plate from a plate-making device to a printing section of a rotary printing press, and to mount the printing plate on a plate cylinder by a robot. The present invention relates to a printing plate conveyance/attachment/removal system for removing unnecessary printing plates from the printing cylinder and discarding the plates.

[Conventional technology]

There has been a system in which the destination is specified with a push button and the printing plate is transported from the plate-making device to a single general carrier, but there is currently no system that automatically loads the required printing plate onto the four-plate cylinder. Not yet.

[Problem that the invention seeks to solve]

The ``Newspaper Printing and Shipping Automation System'' completed at the Nihon Keizai Shimbun Obe Factory (Chiyoda Sogyo) in 1971 is a system that uses computers to consistently control the process from printing to shipping.
nt Computerized System), and system automation has progressed from "line" to "plane", and more recently, total systemization is being considered to "three-dimensional".

The total system as described above consists of 1 rotary press management department, plate conveyance management department, 9 shipping sorting management department, truck yard bundle integration management department, and other groups that require high-speed real-time processing, and 2 paper storage management departments 1 shipping material supply management department. A group capable of relatively low-speed processing such as the Materials and Maintenance Management Department, a group capable of offline processing such as the Materials and Maintenance Management Department, and a command information processing group such as the Sales Volume Change Management Department.
There is a production process management department that collectively manages the groups that require high-speed real-time processing and the groups that can be processed at relatively low speeds.

Each given process is executed by either a processor or an intelligent input/output controller.

As mentioned above, all printing plate loading and unblocking work has traditionally been done manually, but in completing the total system, two-board printing will save labor by automating these tasks. It is also desirable to prevent misprinting due to errors in the printing plate mounting position.

[Means for solving the problem] The present invention automatically transports a printing plate created by a plate-making device to a printing plate installation position of a required printing section, and automatically transfers the printing plate to a plate cylinder by a robot. We provide a system that removes the printing plate from the plate cylinder and discards the plate when updating the printing plate.
