The present invention relates to an invention of a manufacturing system for a plate base material of a gravure plate-making roll, and more specifically, relates to a fully automatic manufacturing system for a plate base material that can be operated unmanned even at night, and a manufacturing method for a plate base material using the same.

Conventionally, as a plate base material of a gravure plate-making roll, in addition to a steel hollow roll, an aluminum hollow roll or the like has been used.

As a cylindrical body (roll base material) used for a plate base material of an aluminum hollow roll, for example, an aluminum alloy is used (Patent Document 1).

In a conventional method for producing a plate base material, an aluminum degreasing process - an aluminum etching process - a decontamination process - an electroless zinc plating process - is sequentially performed on a cylindrical body (roll base material) such as an aluminum alloy as shown in Patent Document 1. Decontamination procedure - electroless zinc plating procedure - nickel strike plating procedure - alkali copper plating procedure - copper plating procedure processing procedure.

The plate base material produced in this way is called "aluminum hollow roll" or the like, although copper plating is applied to its surface, and is used as a plate base material.

For example, the "aluminum hollow roll (plate base material)" used in the Example of Patent Document 2 refers to an aluminum hollow roll to which base copper plating is applied to the surface, manufactured as described above.

When manufacturing such a plate base material, in each of the above-mentioned aluminum degreasing process or aluminum etching process, one has to transport the roll base material to each device of the aluminum degreasing device or the aluminum etching device.

In addition, as shown in Patent Document 3, a method of multiplexing production, recovery processing, and plate making of a plate-making roll for gravure printing using a stacker crane is also proposed.

However, in the production line using such a stacker crane, there is a problem that it takes a corresponding amount of time to hold the aluminum rolls while holding the aluminum rolls by using the roll loading and unloading rotating device or the cassette-shaped roll holding and rotating conveying unit, and transporting the aluminum rolls to the respective processing apparatuses in sequence. . In addition, in the case of a production line using a stacker crane, the rollers are nipped by the roll attachment and detachment rotating device, and are transported to the processing device in sequence, so the processing devices must be arranged in parallel, and there is also a problem that a large installation space is required. Further, in the case of a production line using a stacker crane, the roller loading and unloading rotating device is used to hold the aluminum roll base material, and at the same time, it is transported to each processing device in sequence, so the processing liquid of the previous process is also brought into the next process. question of doubt.

In addition, in the case of Patent Document 3, phosphoric acid is used for degreasing (immersion degreasing) of the aluminum roll. Phosphorus is an element limited in the concentration of waste water. This treatment requires effort and effort. Therefore, an attempt has been made to find a method that does not use it as much as possible. . [Prior Art Literature] [Patent Literature]
