Fully automatic production system for gravure printing rolls

[0001] The present invention relates to a fully automatic production system for a gravure plate roll having a surface-strengthening coating layer having sufficient strength without using chromium plating and having a gravure cell with a very shallow depth, and in particular, a surface replacing a chromium layer. A fully automatic production system for gravure printing rolls, which is provided with a diamond-like carbon (DLC) layer as a reinforced coating layer and capable of achieving sufficient printing density (optical density, transmittance density) and concealment in gravure printing. About.

Background art

[0002] A conventional gravure printing roll manufacturing process involves degreasing a hollow roll, attaching a copper sulfate plating, performing precision cylinder processing with a grindstone polishing device, coating and forming a photosensitive film, and then performing image exposure by laser single exposure. Baked, developed, corroded to form cells, resist stripped, chrome plated, and ground to remove by paper polishing. For iron hollow rolls, degrease and attach nickel plating to add copper sulfate plating, and for aluminum hollow rolls, zinc pretreatment with zincate method or Anodal method. When the copper sulfate plating was added, the cocoon treatment process was performed.

[0003] A conventional gravure plate roll generally has a plate having 175 screen lines per inch and a cell depth of 25 μm to 30 μm at the most shadow portion. In addition, gravure printing is performed using gravure inks containing inorganic pigments and organic pigments in which particles having a particle size of 2 to 3 m or more account for 90% or more.

[0004] The basic composition of the ink consists of a pigment that is a substance that colors the ink as the main agent, a resin that is a substance that fixes and uniformly disperses the pigment on the printed material, and the fluidity, transferability, and drying properties of the ink. Solvent, which is a substance that adjusts etc .: The four powers of vehicle and additive that add various effects such as foam extinguishing and antistatic as auxiliary agent!

[0005] Solvents for oil-based inks include toluene, xylene, ethyl acetate, n-propyl acetate, MEK, MIBK, IPA, ethanol, and n-propanol. Ethanol, _n -propanol, IPA, water are used.

[0006] Chemical substances used in oil-based inks such as toluene and cocoon (1) have a strong pungent odor. (2) Because of its low flash point and high volatility, it tends to ignite and explode when full. (3) If it is sucked by the human body, it will cause health damage. (4) The environment is also affected. (5) Negative for reducing carbon dioxide emissions.

[0007] Organic compounds (VOC) such as solvents that evaporate in the printing process are (1) discharged outside the factory, leading to air pollution and odor problems around the factory. (2) If the product cannot be discharged, the factory fills up and there is a danger of the work environment, such as the danger of ignition and explosion, and the health of workers. (3) Solvent that cannot be evaporated remains on the film and causes the peculiar smell of the printed bag. Especially in the food industry.

[0008] Residual solvent problem not only lowers the image of products, but in the case of foods, it may impair the flavor or easily absorb odors, and may change the taste! .

[0009] Water-based inks basically use water and alcohol to solve various problems of oil-based inks. The problem of remaining ethanol remains. However, ethanol + water does not change the flavor of the contents without a strong pungent odor. The effects of ethanol are much lower than the acceptable range for environmental and health effects. The factory is filled with ethanol, but there is almost no odor. However, since it is an alcohol, it is not without danger of ignition, but it is considerably less dangerous than organic solvents.

[0010] A gravure plate produced by conventional laser plate making generally has 175 screen lines per inch, and the cell depth of the shadow portion is 20 μm to 30 μm. A version is used. When water-based gravure printing is performed under these conditions, plate fog is likely to occur because the ink drying speed is slow. Since the drying speed of the ink is slow, it is necessary to lower the printing speed as compared with gravure printing using oil-based ink, and the printing efficiency (production efficiency) deteriorates.

[0011] A plate used for water-based gravure printing is characterized in that the cells are shallower and the number of screen lines is shallower than oil-based Daravia printing in order to increase the drying speed of the ink. This makes it possible to print with a texture different from oil. In general, the color becomes brighter, the halftone dot reproducibility (fine strength, place) is improved, the highlighting is improved, and the shallow plate is used to reduce the amount of ink used. The effect of the solvent is further reduced by reducing the amount. A gravure printing method using a water gravure ink and a plate with a mesh line strength of 200 to 400 lines and a plate depth of 10 to 17 m has been proposed.

In gravure printing, a gravure printing roll (gravure cylinder) is formed on a gravure printing roll (gravure cylinder) by forming a minute recess (gravure cell) according to the plate making information, and then the gravure cell is filled with ink. It is transferred to printed matter. In general gravure plate-making rolls, a copper plating layer (plate material) for forming a plate surface is provided on the surface of a metal hollow roll such as aluminum or iron, and the copper plating layer is etched in accordance with plate-making information by etching. Forming a small concave part (gravure cell) and then forming a hard chrome layer by chrome plating to increase the press life of the gravure plate making roll to form a surface-enhanced coating layer, and plate making (plate surface production) is completed To do. However, because the chromium plating process uses highly toxic hexavalent chromium, there is an extra cost to maintain work safety, and there is also a problem of pollution. A surface-enhanced coating layer that replaces the chromium layer. The current situation is that the appearance of

The mounted hollow roll 16 is received. The stagger crane 23 lifts the cassette-type roll chuck rotary conveyance unit 33 and sets it on the hollow roll 16 mounted on the four conical rolls of the relay stand device. Then, the cassette-type roll chuck rotary conveyance unit 33 chucks both ends of the hollow roll 16, and the stagger crane 23 lifts the cassette-type roll chuck rotary conveyance unit 33 and conveys it between the units.

[0037] Next, the configuration of the robot chamber A2 will be described. In the robot room A2, reference numeral 12b is an industrial robot acting as a second automatic transfer means, and has a robot arm 14b.

Reference numeral 46 denotes a DLC film forming system (DLC film forming means) for forming a DLC film. The DLC film forming system 46 has a roll mounting table 48 for rotating and mounting the hollow roll 16. The PVD method or CVD method can be used to form the DLC film. As the PVD method, a known method such as a sputtering method, a vacuum deposition method (electron beam method), an ion plating method, an MBE method (molecular beam epitaxy method), a laser ablation method, or an ion assist film forming method can be applied. . CVD methods include APCVD (Atmospheric Pressure Chemical Vapor Deposition), which is formed at normal pressure, LPCVD (Low Pressure Chemical Vapor Deposition), which is formed at a reduced pressure of about 0.05 Torr, and a pressure of about 600 Torr, which is slightly lower than normal pressure. SACVD method (Subatmospheric Pressure Chemical Vapor Deposition), ultra-high vacuum UHVCVD method (Ultra-High-Vacuum Chemical Vapor Deposition), 600 ~: Using high-temperature plasma CVD at high temperature of L000 ° C, 200 ~ Plasma-enhanced chemical vapor deposition (Plasma-Enhanced Chemical Vapor D osition), film formation at 450 ° C, photo-CVD using ultraviolet excitation, MOCVD method for compound crystal growth using organometallic as the source (Metal Organic Chemical Vapor Deposition) can be applied. The hydrocarbon-based raw material gas used to form the DLC film by the CVD method includes one or more known gas types such as cyclohexane, benzene, acetylene, methane, butylbenzene, toluene, and cyclopentane. Is used.

[0039] Therefore, the DLC film forming system 46 is an apparatus capable of practicing the above method. Conventionally known sputtering equipment, vacuum deposition equipment, ion plating equipment, MBE equipment, laser ablation equipment, ion assist deposition equipment, APCVD equipment, LPCVD equipment, SACVD equipment, UHVCVD equipment, thermal CVD equipment, plasma CVD equipment, optical CVD equipment, MOCVD equipment, etc. can be used.

[0040] When a DLC film is formed by the PVD method, a metal layer and a metal carbide layer, preferably a metal carbide layer, are formed from the copper plating layer side in order to improve the adhesion between the copper plating layer and the DLC film. It is preferable to provide an inclined layer. The metal in the metal layer is preferably a metal that can be carbonized and has a high affinity for copper. As this metal, tungsten (W), silicon (Si), titanium (Ti), chromium (Cr), tantalum (Ta), zirconium (Zr), or the like can be used. The method for forming the metal layer and the metal carbide layer is not particularly limited, but using the same type of method as the method for forming the DLC film makes it possible to use the same apparatus, which is preferable.

[0041] As the metal in the metal carbide layer, preferably the metal carbide inclined layer, the same metal as the metal layer is used. The composition ratio of carbon in the metal carbide gradient layer is set so that the carbon ratio gradually increases from the metal layer side to the DLC coating direction. In other words, the film is formed so that the composition ratio of carbon increases from 0% to gradually (stepwise or steplessly), and finally becomes 100%.

[0042] In this case, a known method may be used as a method for adjusting the composition ratio of carbon in the metal carbide layer, preferably the metal carbide inclined layer. For example, a sputtering method (using a solid metal target, an argon gas atmosphere The amount of carbon in the metal carbide layer is gradually increased in a stepped or stepless manner by increasing the injection amount of hydrocarbon gas such as methane gas, ethane gas, propane gas, butane gas, and acetylene gas). It is possible to form a metal carbide layer, that is, a metal carbide gradient layer, in which the thread and composition ratio of both carbon and metal are changed so that the side force gradually increases stepwise or steplessly in the direction of the DLC film. it can.

[0043] By adjusting the carbon ratio of the metal carbide layer in this manner, the adhesion of the metal layer and the metal carbide layer to both the copper plating layer and the DLC film can be improved. Further, if the injection amount of the hydrocarbon gas is made constant, a carbonized metal layer having a constant composition ratio of carbon and metal can be obtained, and the same action as that of the metal carbide inclined layer can be performed. [0044] Further, in forming the DLC film by the CVD method, it is preferable to form the DLC film with a force by providing an adhesion layer on the copper plating layer. The adhesion layer is preferably formed of one or more selected from the group force of aluminum (A1), phosphorus (P), titanium (Ti), and silicon (Si) force. The method for forming the adhesion layer is not particularly limited, but using the same type of method as that for forming the DLC film is preferable because the same apparatus can be used. When forming an adhesion layer by CVD, trimethylaluminum, titanium tetrisopropoxide, titanium tetraethoxide, tetramethylsilane, trimethyl phosphite, hexamethyldisiloxane group power, one or more selected gases It is preferred to use seeds.

[0045] Reference numerals 18c and 18d denote roll stock apparatuses. For this roll stock device, for example, the roll stock device disclosed in Patent Documents 1 to 3 can be used.

Next, the operation of the fully automatic production system 10 for a gravure printing roll will be described. The hollow roll 16 is stocked in the roll stock devices 18a and 18b, then degreased by the electrolytic degreasing unit 44, and copper sulfate plated by the copper plating unit 40, and precision cylindrical processing is performed by the automatic polishing device 20. Then, a photosensitive film is applied and formed by the photosensitive film coating apparatus 22. Then, an image is printed by laser exposure with the laser exposure device 24, developed with the developing unit 28, washed with water with the washing / drying unit 30, and corroded with the corrosion unit 36 to form cells. Then, the resist stripping unit 38 performs resist stripping, and the DLC pretreatment unit 34 performs DLC pretreatment.

Thereafter, the DLC film is formed on the hollow roll 16 by the DLC film forming system 46.

The hollow roll 16 on which the gravure cell is formed is stocked in, for example, a roll stock apparatus 18d, and then automatically loaded into the DLC film forming system 46 by the robot arm 14b. The hollow roll 16 on which the DLC film is formed by the DLC film forming system 46 is stocked, for example, to the roll stock apparatus 18c and is carried away. In this way, the gravure plate roll 50 is fully automatic.
