In the handling area of the industrial robot 3 in the plate making room H1, when one device is in operation, the plate making roll R, which has progressed to the step of being processed by the one device, is stocked in the stock device 8.

The laser ablation device 4 receives and rotates the handling work W placed on the work placement table 11 and transported by the industrial robot 3 with both ends supported by a pair of conical chucks, and rotated. 1
The laser beam is ablated by flashing and irradiating a laser beam to the black film applied to the non-image portion to form a black film negative image corresponding to the non-image portion. The laser ablation device 4 can use a laser beam of a yag laser, an infrared laser, or a semiconductor laser that emits a laser beam having a wavelength of about 800 nm. In laser ablation, a laser beam is absorbed by a black film and converted into heat, and a combustible substance constituting the black film is heated and evaporated instantaneously under an oxidizing agent. When the laser ablation is completed, it is handed over to the industrial robot 3. Since the flexographic printing plate material 1 is expensive and cannot be used wastefully, a large number of printed originals are laid out on a computer display and laid out so as not to cause a large gap. Outputs ablation. After the completion of plate making, the plate is peeled off, cut for each plate, adhered to a printing roll, and provided for printing.

The developing device 6 is rotated while supporting both ends of the handling work W conveyed by the industrial robot 3 after the latent image is formed by the industrial robot 3 by a pair of conical chucks. After removing the black film negative image of No. 1, the unexposed non-image area resin portion covered with the black film negative image is eroded with a developing solution, and the exposed and cured portion is left as a letterpress portion. In order to effectively reduce the erosion by the developer, the flexographic printing plate 1 is subjected to shower development and the brush roll is rotated in contact with the plate. Thus, the black film is removed by the brush roll, and the developer is constantly brought into contact with the uncured resin portion by the brush roll to perform erosion. Further, it is preferable that the lower side of the handling work W is immersed in a developer and irradiated with ultrasonic waves. When the resin constituting the outer layer portion of the flexographic printing plate material 1 is soluble in a solvent, a solvent is used in the developing solution. When the resin is soluble in water, water can be used in the developing solution. When the development is completed, it is handed over to the industrial robot 3.

The whole-surface exposure drying device 7 rotates the supporting work W which is conveyed while being held by the industrial robot 3 with both ends supported by a pair of conical chucks after the development, and emits from a UV light source. About 2 UV
By irradiating the entire surface for 0 minutes, the flexographic printing plate 1
Is irradiated with light of a required wavelength to expose and harden the entire surface to dry the flexographic printing plate material 1 and to retain corrosion resistance during printing. The whole-surface exposure / drying device 7 is preferably provided adjacent to the whole-surface exposure / latent image forming device 5 because it has no difference in mechanical and electrical configuration. The whole-surface exposure / latent image forming device 5 and the whole-surface exposure drying device 7 can be used for both purposes. Although the production capacity is reduced, one unit can be omitted to reduce equipment costs and save space.

The stock device 8 is provided on the entire-surface exposure / latent image forming device 5 and the entire-surface exposure / drying device 7 which are low in device height. In the handling of the industrial robot 3, when one device is in operation, the handling work W that has progressed to the step of being processed by the one device is stored in the stock device 8. Since the present invention enables unattended full-automatic plate making at night, the stock apparatus 8 is provided with a number capable of stocking a maximum number of processing works, preferably 20 to 40 handling works W overnight. .

The unloading device 9 is designed so that the handling work W, which has completed plate-making, is heavy, so that the handling work W which is conveyed while being clamped at both ends by the industrial robot 3 can be horizontally picked up and taken out. It is configured. The unloading device 9 can lean the plurality of handling works W processed at night at a time at an angle, and thus can quickly empty the stock device 8 at the start of plate making in the morning.
