Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a case where extraction of roll data and exclusion of inappropriate rolls can be performed, and precision polishing can be performed fully automatically from plate drop polishing to mirror polishing, and cell formation is performed by etching. It can be applied to both the engraving and engraving.It is the first roll to be used after the roll is manufactured and does not require polishing. The present invention relates to a gravure plate making apparatus in which fully automatic plate making can be applied to any of recycle rolls requiring a processing step until polishing.

2. Description of the Related Art Conventionally, a gravure plate making apparatus has been developed with completely different concepts by an apparatus manufacturer (the applicant of the present application) that forms cells by etching and an apparatus manufacturer (another company) that performs engraving. , There is no detect standard. For this reason, most of the printing companies and plate making companies that perform plate making have various devices of a plurality of companies, and many processes are not lined up. The reason is that the manufacturer of the electronic engraving machine is not a manufacturer of the plating apparatus and the polishing apparatus, and conversely, the manufacturer of the plating apparatus and the polishing apparatus is not the manufacturer of the electronic engraving machine. The plate making process involves a complicated process of performing dechroming treatment, polishing, then plating, polishing again, and then performing chromium plating. Except for the above, there was no other manufacturer providing tall line equipment. As for the plate making line where cells are formed by etching, mirror polishing-photosensitive film coating-
Laser exposure and latent image formation-
Attention has been focused on a plate making process in which mirror polishing, laser ablation film coating, laser ablation, resist image formation, and corrosion proceed. The advantages are (1)
The delicate correlation that the development process is eliminated, (2) plate making in a bright room becomes possible, and (3) the laser exposure becomes over-exposed or less when the thickness of the photosensitive film changes by 1 micron. (4) The chemical correlation between the photosensitive solution and the developing solution can be eliminated. If the compatibility of the two solutions is poor, development residues remain, or the contour of the exposed portion is largely retreated (dissolved) by development. It is mentioned. However, laser ablation and resist image formation
Regarding the plate making process that progresses with corrosion, several laser ablation / resist image forming devices have come on the market as stand-alone machines, but none of them have been put into practical use. It has not been done yet.

[0003]

Many printing companies and plate making companies that perform plate making often input 20 to 40 plate making rolls one after another in the evening and input the plate making method and contents to a controller. It is desired to provide a total line device that can be fully automated in the nighttime and can be fully automated in the evening. The problems here are as follows. (1) Instead of a plate making method in which a photosensitive film is coated, laser-exposed and developed to form a resist image and etched to form a cell,
Some companies want to provide a plate making method of forming a cell by forming a resist image by black coating and laser ablation and etching. The plate making method of forming cells by forming and etching a resist image by black coating and laser ablation, and the plate making method of forming cells by engraving have advantages and disadvantages. Wants to offer. In particular, it is desired to provide a total line device including an already-equipped electronic engraving machine and a plating device. The plate making method of forming a cell by forming a resist image by black coating and laser ablation and etching is a plate making method of forming a resist image by forming a resist image by coating a photosensitive film, laser exposing and developing, and forming a cell. It has exactly the same features and can realize a free flow cell that can cut the intersection of screen lines.
In addition, since the outline of the character can be formed in a continuous groove through which ink does not flow, the plate making method in which the cells are formed by engraving rather than the plate making method in which the cells are formed by engraving is used for a plate having only solid images and characters. Is better. The gradation of the highlight portion is expressed by the area of the cell when the cell is formed by etching, and is expressed by a diamond-shaped cone when the cell is formed by engraving. There is a difference in expressing the gradation, and the precision of expressing the gradation in the highlight portion is more excellent when engraving the cells when using oil-based ink. When the total line device as described above is provided, it is possible to separately cope with the case where the cell is formed by etching and the case where the cell is formed by engraving, depending on the contents of the plate. (2) A roll to be used for the first time after the roll is manufactured, the mirror polishing has been completed, and no polishing is required. There is a demand that fully automatic plate making be applied to any plate-making roll that requires a processing step from plate drop polishing to mirror surface polishing. Also in this case, there is a demand that the cell formation be applied to both etching and engraving. (3) There is a demand that the polishing process can be greatly shortened, the cylindrical accuracy is higher than before, and mirror polishing that does not rely on buff polishing is realized. Polishing after the conventional dechroming treatment is, for example, correction polishing with a # 320 polishing wheel-plate removal with a # 320 polishing wheel-cylindrical polishing with a # 500 polishing wheel-
Cylindrical polishing with a # 800 grinding wheel was performed. Or
Polishing after conventional copper plating, for example, # 800, # 1000, # 12
Cylindrical polishing was performed by each of the grinding wheels of 00, # 1500, # 1800, # 2000, # 2500, and # 3000, and finally, mirror polishing by a buff was performed. (4) In recent copper plating treatments, sulfur-based compounds contained in brighteners and hardeners form a boundary film between nickel plating and copper plating and the adhesion strength of copper plating is weakened. There is a problem that it is necessary to strongly secure the adhesion strength of the copper plating applied on the substrate. Conventional plate-making roll production, for example, on an iron roll base material,
After cylindrical polishing with a # 320 grinding wheel and further degreasing, nickel plating is applied to a thickness of 2 to 3 μm, or an aluminum roll base material, for example, # 3
After being cylindrically polished with 20 polishing wheels, nickel plating was applied to a thickness of 2 to 3 μm. Subsequently, copper plating was applied to a thickness of, for example, 100 μm. In the conventional copper plating method, a plate-making roll with nickel plating is rotatably chucked at both ends and positioned in a plating bath, and then a copper plating solution is put into the plating bath and the plate-making roll is immersed in about one minute. About 15 minutes after spinning
Copper plating was performed by applying a plating current so that a voltage of V was applied. In order to reduce the time, the inventor of the present application started the plate drop polishing by a method in which two opposite # 320 polishing grindstones were used to polish the plate-making roll with a polishing pressure larger than before by sandwiching the plate-making roll. The plating peeled off from the nickel-plated surface as if it were ballad plating. After investigating the cause, it was found that a peelable boundary film was formed between the nickel plating and the copper plating.
More specifically, in recent years, in order to improve workability, a brightening agent or a hardening agent has been put into a copper plating solution and plating has been performed. As described above, a plate-making roll is immersed in a copper plating solution. After about one minute has passed, when the plating current is applied by rotating, the sulfur-based compound contained in the brightener or hardener is applied to the nickel-plated surface before copper plating is performed on the nickel-plated surface. (For example, Bis.S.Propyl.Sulfonate.N [Bis.S.Propyl.Sulfonate.N]
a] and two mercapto. Monomethyl. Imidazole [2 Merc
apto1Methyl Imidazole]) was found to form a detachable limiting membrane.

The present invention has been devised in view of the above-mentioned points, and can extract roll data and exclude improper rolls, and when a type of plate making process is input, automatically performs from plate drop polishing to mirror polishing. Precise polishing can be performed, cell formation can be applied to both etching and engraving, and it can be applied to both first-use rolls that do not require polishing and reused rolls that require polishing. Related to the device.

A polishing machine 9 and a roll stock device 10 are provided. Roll stock device 10
Is provided on the laser ablation film coating device 6 and the ablation laser device 7. It should be noted that a two-head type polishing machine having a pair of opposing rough finish polishing wheels 9a and 9b of # 320, and a two-head type polishing machine having a pair of opposing pairs of # 1000 semi-finishing polishing wheels 9c and # 6000 precision polishing wheels 9d are provided.

The plate making roll R is tilted up to about 80 degrees so that the plate making roll R can be manually moved upright and rolled. The laser ablation film coating device 6 is a device for coating and forming an etching resistant film capable of laser ablation, and may be either a scan coat type device or a dipping type device. For example, combustible substances (nitrocellulose, ethylene vinyl acetate strong polymer, unsaturated polyester resin, epoxy resin, allyl resin, polyurethane resin, polyethylene, polypropylene, polystyrene, polyacetal, tennene rubber, etc .: 75 or more) Wt.%), An oxidizing agent (ammonium nitrate or chloric acid compound: 10 wt.%), And a light absorbing material (carbon black: 15 wt.%), Which is laser-ablation-resistant and has a thickness of several micrometers.

Perform laser ablation. That is, the laser beam is absorbed by the light absorber, converted into heat, and the combustible material is heated and evaporated instantaneously under an oxidizing agent, so that the copper plating surface for etching is exposed to correspond to the image area. I do. The polishing machine 9 performs the following polishing operation. After the chromium removal treatment, plate finish polishing-correction polishing-surface roughness miniaturization polishing is performed by the rough finish polishing grindstones 9a and 9b.
The rough finish polishing whetstones 9a and 9b have a crossing angle of 90 degrees when both the extension line of the rotation axis of the whetstone and the rotation axis of the plate making roll are viewed from a plane direction, and a contact line at the time of polishing the end face of the whetstone. However, it is configured to be able to perform polishing while maintaining a constant polishing pressure within a range of a chord line parallel to the diameter line passing through the center of the center hole of the end face of the whetstone or the diameter line which does not deviate from the center hole. I have. Then, correction polishing is performed to reduce the deviation of the diameter based on the diameter measurement value, and then movement from one end of the plate-making roll to the other end is repeated to remove the plate engraved on the plate-making roll. Then, the surface roughness miniaturization polishing is performed in such a manner that the side where the rotation direction of the grindstone and the plate making roll coincide with each other is the rear side in the moving direction with respect to the surface length direction of the plate making roll. After the copper plating, the surface is polished to a finer surface roughness with a # 1000 semi-finishing polishing grindstone 9c. The intermediate finish polishing grindstone 9c also has an intersection angle of 90 degrees when both the extension line of the rotation axis of the grindstone and the rotation axis of the plate making roll are viewed from a plane direction, and the contact line at the time of polishing the end face of the grindstone is The polishing is performed while maintaining a constant polishing pressure within a range of a diameter line passing through the center of the center hole of the end face of the whetstone or a chord line parallel to the diameter line to the extent that the center hole is not deviated. Then, the surface roughness miniaturization polishing is performed such that the side where the rotation direction of the grindstone and the rotation of the plate making roll coincide with each other is the rear side in the moving direction with respect to the surface length direction of the plate making roll.
Subsequently, the surface roughness is reduced and the mirror surface is polished by a # 6000 precision polishing grindstone 9d. The precision polishing whetstone 9d has a crossing angle of 90 ° when viewed both from the plane of the extension line of the rotation axis of the whetstone and the rotation axis of the plate-making roll rather than 90 °. The line is within the range of the diameter line passing through the center of the center hole of the end face of the grinding wheel or the chord line parallel to the diameter line of the limit which does not deviate from the center hole, the polishing pressure is kept constant, and the peripheral speed of the plate making roll and The grinding wheel is polished while moving in the direction of the surface length of the plate making roll while making the rotation speed at one point on the contact line of the grinding wheel substantially coincide with each other. In the handling area of the industrial robot 1 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 roll stock device 10.

[0011] In the roll transport area of the stacker crane 2 in the plate making room H2, a dechroming device 11 and a surface activating device 1 are provided.
2, a nickel plating device 13, and a copper plating device 14
, A chrome plating device 15, a corrosion device 16, and a stocking device 17 for stocking the roll attaching / detaching rotating device 3 in a line. The surface activating device 12 is immersed in an alkaline solution to degrease, then pickled by a shower of an acidic solution, and then washed by a water shower. The dechroming device 11
A pair of opposed chuck devices (not shown) is provided, and the plate making roll R can be exchanged with the robot hand 1b of the industrial robot 1. The dechroming device 11 is provided with a plate roll R
Is immersed in hydrochloric acid to dissolve the chromium. Chromium removal device 11
The roll removing / rotating device 3 mounted on the chromium removing device 11 can transfer the plate-making roll R with the robot hand 1b of the industrial robot 1. At this time, the pair of chuck devices (not shown) provided in the dechroming device 11 are configured to swing sideways and wait. Plate roll R
The roll detaching / rotating device 3 which has been chucked is lifted and transported by the stacker crane 2. The nickel plating apparatus 13 performs nickel plating so as to have a thickness of, for example, 2 to 3 μm. After the plate making roll is positioned in the plating bath, the nickel plating solution is put into the plating bath, the plate making roll is immersed in the plating solution, and then the plate is rotated.
Plating is performed by applying a voltage of V. In addition, in order to apply nickel plating to the aluminum roll base material, for example, a zincate treatment is performed as a pretreatment to form an interface thin film that improves adhesion, but the nickel plating is not exposed in the plate drop polishing of the recycling roll. The polishing is performed as described above, and the interface thin film forming process is set off-line. The copper plating apparatus 14
For example, nickel plating is applied to a thickness of 100 μm. After the plate making roll R is chucked at both ends and positioned in the plating bath, the plate making roll R is rotated by applying a low voltage (for example, 1 V to 5 V) that does not cause electric burning. Then, the level of the copper plating solution in the plating bath is slowly raised, and the level of the copper plating solution is brought into contact with the plate-making roll R to apply copper plating to the entire peripheral surface. Since the plating current flows at the moment when the copper plating solution comes into contact with the plate making roll R, the deposition of copper plating is performed instantaneously, and the reaction speed of the sulfur-based compound contained in the brightener and the hardening agent is low. The sulfur compound does not form a boundary film between nickel plating and copper plating.
Also, since the voltage is low, the copper plating does not burn. afterwards,
As the liquid level of the copper plating solution is increased, the voltage is gradually increased so that the plating voltage becomes 15 V when the roll is completely immersed, and copper plating is performed. In this case, the sulfur compound is incorporated into the copper plating, but does not give the copper plating releasability. The chrome plating device 15 has a thickness of 8 μm, for example.
Chrome plating so that Plate making room H2
In the roll transport area of the stacker crane 2, when one apparatus is in operation, the plate making roll R, which has progressed to the step of being processed by the one apparatus, is kept chucked by the roll attaching / detaching rotary apparatus 3 and the stock apparatus Stocked at 17.
