DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gravure plate making apparatus. Extraction of roll data and exclusion of improper rolls can be performed, and precision polishing can be performed automatically from plate drop polishing to mirror polishing, and cell formation can be applied to both etching and engraving. In addition, a roll to be used for the first time after the roll is manufactured and requires no polishing, and a plate-making roll to be inserted immediately from the cell formation process, and a recycled roll which requires a process of dechroming, plate-down polishing, and mirror polishing. Fully automatic plate making can be applied to any of

[0002]

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 total line equipment.

[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 stocked in a plate making room and perform unattended full automatic plate making at night. The problems here are as follows. (1) The plate making method of forming cells by etching and the plate making method of forming cells by engraving have advantages and disadvantages.
We hope to provide a total line device that can be freely selected in any case. In particular, JP-A-10-193551 and JP-A-10-19, which are the total line apparatus of the applicant of the present invention.
It is desired to provide a total line device based on 3552 and an electronic engraving machine which is already provided. When cells are formed by etching, a free-flow cell that can cut the intersection of screen lines can be realized, and the character outline can be formed in a continuous groove through which ink does not flow. As for a plate, a plate making method in which cells are formed by etching is superior to a plate making method in which cells are formed by engraving. or,
When the cell is formed by etching, the gradation is expressed by the area of the cell. When the cell is formed by engraving, the gradation is expressed by a diamond-shaped cone. In the case of using oil-based ink, it is better to form cells by engraving 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, plate removal using a # 320 polishing wheel-correction polishing using a # 320 polishing wheel-cylindrical polishing using 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 to reduce the adhesion strength of copper plating. 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. For this reason, polishing takes too much time. In order to shorten the time, the inventor of the present invention started the plate drop polishing by a method in which two opposite # 320 polishing grindstones were used to apply a polishing pressure with a plate-making roll sandwiched therebetween, and started plate drop polishing. It peeled off from the nickel plating surface as if it were plating. After investigating the cause,
It was found that a peelable boundary film was formed between nickel plating and copper plating. More specifically, in recent years, in order to improve workability, a brightener or a hardening agent has been put into a copper plating solution and plating has been performed. Sulfur-based compounds (for example, bis.S.propyl.sulfonate.sodium [Bis.S.Propyl.Sulfonate.Na]) and dimercapto.1-methyl.imidazole [2Mercapto1Methyl] Imidazol
e)) was found to form a peelable boundary film.

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.

The roll measuring device 4 measures the total length, outer diameter, hole diameter, and diameter of the plate making roll from one end to the other end of the roll at regular intervals. The polishing machine 9 performs the following polishing operation. Plate removal polishing by rough finish polishing whetstones 9a and 9b after dechroming treatment
Correction polishing-polishing for miniaturizing surface roughness. The rough finishing abrasive wheels 9a and 9b have an intersection angle of 90 when both the extension of the rotation axis of the grinding wheel and the rotation axis of the plate making roll are viewed from the plane direction.
And the contact line during polishing of the end face of the grinding wheel is within a range of a chord line parallel to a diameter line passing through the center of the center hole of the whetstone end face or a diameter line not exceeding the center hole, and the polishing pressure. It is configured so that polishing can be performed while maintaining a constant. 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 semi-finished polishing wheel 9c also has an intersection angle of 90 when both the extension of the rotation axis of the grinding wheel and the rotation axis of the plate making roll are viewed from the plane.
And the contact line during polishing of the end face of the grinding wheel is within a range of a chord line parallel to a diameter line passing through the center of the center hole of the whetstone end face or a diameter line not exceeding the center hole, and the polishing pressure. It is configured so that polishing can be performed while maintaining a constant. 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. Then, # 600
Polishing with miniaturization of surface roughness and mirror polishing are performed by a 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 chromium plating device 15, a developing device 16, a corrosion device 17, a resist stripping device 18, and a stock device 19 for stocking the roll detaching rotating device 3 in a row. 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 chromium removing device 11 dissolves the chromium by immersing the plate making roll in hydrochloric acid. 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, a nickel plating solution is put into the plating bath, and the plate-making roll is immersed in the plating solution, and then rotated to 15 V.
Apply voltage and plate. 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 performs, for example, nickel plating so as to have 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 19.

The procedure is as follows: loading-roll measurement-photosensitive film coating-laser exposure latent image formation-development-corrosion-resist stripping-chrome plating-carry-out. In the plate making process (D), carry-in, roll measurement, image engraving, chrome plating, and carry-out are performed.

The plate-making process (A) is a recycle roll in which the plate-making roll R needs a processing step from dechroming, plate-drop polishing, and mirror polishing. Input designation to 20. The plate-making process (B) is a recycle roll in which the plate-making roll R needs a processing step from dechroming, plate-drop polishing, and mirror polishing, and when the cell formation is performed by engraving, an input designation to the controller 20 is performed. I do. In the plate making step (C), the plate making roll R is not a recycle roll but a roll to be used for the first time after the roll production, and is a plate making roll that requires no polishing and is immediately inserted from the cell forming step. Is input and designated to the controller 20. The plate-making process (D) is a plate-making roll in which the plate-making roll R is not a recycle roll but a roll used for the first time after the roll is manufactured and polishing is not required, and is immediately started from the cell forming step. In this case, the input is designated to the controller 20.

The plate-making roll to be carried into the plate-making room is configured to be placed on the mounting plate of the handling device 21, open the sliding door, sent in, and artificially attached to the roll measuring device 4 to perform roll measurement, as described above. And the controller 20
When the type of the plate making process (A), (B), (C), or (D) is input, when the plate making process (A) and the plate making process (B) are input, the total length of the plate making roll, outside The roll data such as the diameter, the hole diameter, and the outer diameter every time a predetermined pitch is separated from the roll end are extracted and input to the controller. As a result of extracting the roll data such as the outer diameter at every predetermined pitch from the roll end, if the roll is incorrect data roll, it is artificially excluded. Further, when the plate making process (C) and the plate making process (D) are inputted, roll data of the total length, outer diameter and hole diameter of the plate making roll are extracted and inputted to the controller. When inputting the plate making process (C) and the plate making process (D), the plate making roll R is not a recycle roll but a roll used for the first time after the roll is manufactured, and the plate making roll which is not required to be polished and immediately enters from the cell forming step. Therefore, it is assumed that there is no roll of inappropriate data.

When the plate making roll R is carried into the plate making room and is artificially attached to the roll measuring device 4, the controller 20
Except for the case where the type of the plate making process is input to the machine, the case where the plate making roll R of inappropriate data is removed from the roll measuring device 4 and the case where the plate making process R is completed and the plate making roll R is removed from the roll unloading device 5. There is no typical work.

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 stocked in a plate making room and perform unattended full automatic plate making at night. The problems here are as follows. (1) The plate making method of forming cells by etching and the plate making method of forming cells by engraving have advantages and disadvantages.
We hope to provide a total line device that can be freely selected in any case. In particular, JP-A-10-193551 and JP-A-10-19, which are the total line apparatus of the applicant of the present invention.
It is desired to provide a total line device based on 3552 and an electronic engraving machine which is already provided. When cells are formed by etching, a free-flow cell that can cut the intersection of screen lines can be realized, and the character outline can be formed in a continuous groove through which ink does not flow. As for a plate, a plate making method in which cells are formed by etching is superior to a plate making method in which cells are formed by engraving. or,
When the cell is formed by etching, the gradation is expressed by the area of the cell. When the cell is formed by engraving, the gradation is expressed by a diamond-shaped cone. In the case of using oil-based ink, it is better to form cells by engraving 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 to reduce the adhesion strength of copper plating. 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 brightener 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. When about 1 minute has elapsed and the plating current has flowed, the nickel-plated surface is subjected to a sulfur-based compound contained in a brightener or hardener before copper plating is performed on the nickel-plated surface. For example, bis.S.propyl.sulfonate.sodium [Bis.S.Propyl.Sulfonate.Na] or dimercapto.1-methyl.imidazole [2Mercapto1
Methyl Imidazole]) was found to form a detachable boundary membrane.
