Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention makes it possible to completely automate the entire plate making process, eliminate the imbalance in the processing capacity (processing time) of each apparatus, and transport the plate making roll. The present invention relates to a gravure plate making factory that can reduce time, can save space in a factory without requiring an automatic warehouse, can operate unattended at night, and can take out processed rolls at the start of operation in a short time. 2. Description of the Related Art A gravure plate-making process of a plate-making roll by an engraving method includes, for example, carry-in, degreasing, washing, pickling, washing with water.
Ballard treatment-water washing-ballad copper plating-water washing-grinding stone polishing-water washing-image engraving-chrome plating-water washing-carrying out process. The steps of degreasing, rinsing, pickling, rinsing, ballad treatment, rinsing, ballad copper plating and rinsing, and chrome plating and rinsing are performed by immersing the plate roll in the processing liquid and rotating. It is necessary to process by chucking the chuck hole and liquid sealing. Therefore, conventionally, a cassette type roll chuck device capable of chucking the chuck holes at both ends of the plate making roll and liquid-sealing and rotating is mounted on a developing device, a corrosive device, a plating device, or the like, and the processing is performed. A stacker crane is used to transfer the devices from one device to another. Other devices include a device that chucks and rotates chuck holes at both ends of a plate-making roll, so that transport and chucking are performed artificially using a balancer, a hoist, or the like. A conventional gravure plate making factory is a plate making process in which a plate making roll is immersed in a processing solution, that is, degreasing-washing-pickling-washing-ballarding-washing-
A ballad copper plating-washing process, a chrome plating-washing process factory, and a plate making process in which a plate-making roll is not immersed in a processing liquid, that is, a grindstone polishing-washing-image engraving-chrome plating-washing process is performed. The factory and the factory are separately built, and the transfer of the plate making roll between the factories is performed artificially using a balancer, a hoist, or the like. In a conventional gravure plate making factory, a plate making roll is transferred between a transfer of a plate making roll by a balancer, a hoist or the like, and a cassette type roll chuck device transferred by a stacker crane. Could not be performed directly, so that the entire plate making process could not be fully automated. Since the various types of processing equipment are not arranged in accordance with the plate making process, the distance for the stacker crane to lift the cassette type roll chuck device and transfer the plate making roll from the processed equipment to the next processing equipment is unnecessarily long. Therefore, it took too much time to carry and the processing capacity did not increase. Unable to operate unmanned at night because the entire plate making process could not be automated. An automatic warehouse for plate-making rolls was required, and it took too much time to take in and out each roll between the plate making factory and the automatic warehouse for plate-making rolls. It took an extremely long time to remove all the processed rolls from the automatic roll of the plate making roll. According to the present invention, the entire plate making process can be completely automated,
Eliminates imbalance in the processing capacity (processing time) of each device, shortens the time required to transport plate-making rolls, saves space in factories without the need for an automatic warehouse, and enables unmanned operation at night.
