Description

Fully automatic plate base material manufacturing system and plate base material manufacturing method

The present invention relates to an invention of a plate base material manufacturing system for a gravure plate making roll. More specifically, a plate base material fully automatic manufacturing system capable of unmanned operation even at night and a plate base material manufacturing method using the same. Regarding.

Conventionally, as a plate base material for a gravure plate making roll, an aluminum hollow roll or the like is used in addition to a steel hollow roll.

For example, an aluminum alloy is used as a cylinder (roll base material) used as a plate base material for an aluminum hollow roll (Patent Document 1).

The conventional method for producing a plate base material is an aluminum degreasing process-aluminum etching process-desmat process-electrolytic zinc plating process-in order for a cylinder (roll base material) such as an aluminum alloy as shown in Patent Document 1. It is manufactured by performing a processing process of desmat process-electrolytic zinc plating process-nickel strike plating process-alkali copper plating process-copper plating process.

Although the surface of the plate base material manufactured in this way is copper-plated, it is called an "aluminum hollow roll" or the like and is used as a plate base material.

For example, the "aluminum hollow roll (plate base material)" used in the examples of Patent Document 2 is an aluminum hollow roll manufactured as described above and having a base copper plating on the surface. be.

In manufacturing such a plate base material, a person may carry a roll base material to each device such as an aluminum degreasing device or an aluminum etching device for each of the above-mentioned aluminum degreasing steps and aluminum etching steps. I had to.

Further, as in Patent Document 3, a method has been proposed in which a stacker crane is used to perform multi-production, recycling processing, and plate-making of a plate-making roll for gravure printing.

However, in the case of a production line using such a stacker crane, aluminum rolls are sequentially delivered to various processing devices while chucking aluminum rolls using a roll attachment / detachment rotary device or a cassette type roll chuck rotary transfer unit. There was a problem that it only took time. Further, in the case of a production line using a stacker crane, since the rolls are sequentially transported to the processing device while chucking the rolls using the roll attachment / detachment rotation device, it is necessary to arrange various processing devices in parallel, which requires a large installation space. There was also the problem that it was necessary. Furthermore, in the case of a production line using a stacker crane, the aluminum roll base material is chucked using a roll attachment / detachment rotation device and sequentially delivered to various processing devices, so that the processing liquid of the previous process is brought to the next process. There was also a problem that there was a risk of contamination.

Further, in the case of Patent Document 3, phosphoric acid is used for degreasing (immersion degreasing) of the aluminum roll, but phosphorus is an element whose wastewater concentration is regulated, and it takes time and effort to process it. I was looking for a way to avoid it if possible.
