Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a paper roll supply system in a printing press, and in particular, to a web feeding system in a printing press, in particular, a web feeding system for a plurality of printing machines based on printing work information necessary for the day's printing work from a host CPU. The present invention relates to a paper roll supply system in a printing machine that automatically supplies the paper roll corresponding to the paper feed section of the printing machine from a paper roll storage and also manages the arrival and shipping of the paper roll in the paper roll storage.

[Prior Art] Each process of printing work, especially the work of the paper feeding section, will be explained.

The number of rolls of paper, their size, and product name are ordered several months in advance.

The paper manufacturer receives the ordered products into the paper roll storage at the printing factory.

Workers organize and store the received rolls of paper by number, product name, and size. Then, the number of rolls of paper to be used for printing on the day is peeled off.

The peeled web is conveyed to the paper feed section by a conveyor.

The worker in charge of each paper feed section selects a paper roll of the required size from among the paper rolls being circulated, and if the direction of the paper roll is in the opposite direction, the worker rotates the paper 180 degrees and then pulls it in. Then, attach it to the supply reel.

An adhesive layer for paper splicing is applied to the end of the paper roll.

After paper splicing is automatically performed, the used core remaining is placed on a trolley and collected by a circulating conveyor.

[Problem that the invention seeks to solve]

Conventionally, each process has been extremely inefficient and requires a great deal of labor and time, as it involves manually processing a large roll of paper as described above. Furthermore, there are cases in which a paper web of a size required during printing is not on the circulation conveyor and must be urgently transported from storage, which often has an adverse effect on the progress of printing.

The ``Newspaper Printing and Shipping Automation System'' completed at the Nihon Keizai Shimbun Osaki Factory (Chiyoda Sogyo) in 1972 is a system that uses computers to consistently control the process from printing to shipping, and is known as the NPC System (Newspaper Plant Computerized System). System automation has progressed from "line" to "plane", and more recently, total systemization is being considered to "three-dimensional".
