Description

[Technical field]

[0001] The present invention relates to a manufacturing system for plate base materials for gravure plate-making rolls, and more particularly to a fully automated manufacturing system for plate base materials that allows unmanned operation even at night, and a manufacturing method for plate base materials using the same. [Background technology]

[0002] Conventionally, as the plate base material for a gravure plate-making roll, in addition to a hollow steel roll, a hollow aluminum roll and the like have been used.

[0003] For example, an aluminum alloy is used as a cylinder (roll base material) used as a plate base material for an aluminum hollow roll (Patent Document 1).

[0004] In the conventional method for manufacturing a plate base material, as shown in Patent Document 1, a cylinder (roll base material) made of an aluminum alloy or the like is subjected to the following processing steps, in order: aluminum degreasing process - aluminum etching process - desmutting process - electroless zinc plating process - desmutting process - electroless zinc plating process - nickel strike plating process - alkaline copper plating process - copper plating process.

[0005] The plate base material produced in this manner has its surface copper-plated, but is called an "aluminum hollow roll" or the like and is used as a plate base material.

[0006] For example, the "aluminum hollow roll (plate base material)" used in the examples of Patent Document 2 is an aluminum hollow roll manufactured as described above, the surface of which is coated with a copper undercoat.

[0007] In manufacturing such a plate base material, a person must carry the roll base material to each device, such as the aluminum degreasing device or aluminum etching device, for each process, such as the aluminum degreasing process and aluminum etching process described above.

[0008] Also, as disclosed in Patent Document 3, a method has been proposed in which a stacker crane is used to perform multiple operations including the production, recycling, and plate making of rolls to be used for gravure printing.

[0009] However, in the case of a production line using such a stacker crane, the aluminum roll is chucked using a roll desorption rotating device or a cassette type roll chuck rotating transport unit and then transferred to various processing devices, which takes time. In addition, in the case of a production line using a stacker crane, the roll is chucked using a roll desorption rotating device and then transferred to the processing devices, which requires various processing devices to be arranged in parallel, which requires a large installation space. In addition, in the case of a production line using a stacker crane, the aluminum roll base material is chucked using a roll desorption rotating device and then transferred to various processing devices, which may cause contamination by the processing liquid from the previous process being carried over to the next process.

[0010] In addition, in the case of Patent Document 3, phosphoric acid is used to degrease aluminum rolls (immersion degreasing). However, phosphorus is an element whose wastewater concentration is regulated, and its treatment is also time-consuming, so we were looking for a method that does not use phosphorus, if possible.

FIG. [Figure 4] FIG. 2 is a cross-sectional schematic diagram showing a roll base material used in the method for producing a plate base material according to the present invention. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0027] The following describes embodiments of the present invention, but these embodiments are shown by way of example only, and it goes without saying that various modifications are possible without departing from the technical concept of the present invention.

[0028] The fully automated system for producing a plate base material according to the present invention will be described with reference to the accompanying drawings. In Fig. 1, reference numeral 10 denotes the fully automated system for producing a plate base material according to the present invention.

[0029] The fully automated plate base material manufacturing system 10 is composed of a processing chamber A, a processing chamber B, and a processing chamber C. The processing chambers A and B, and the processing chambers A and C are separated by walls 11 and 13, and are connected to each other via shutters that can be opened and closed.

[0030] The plate base material fully automated manufacturing system 10 is a plate base material fully automated manufacturing system for manufacturing plate base materials for gravure plate making rolls, and is configured to include an aluminum hollow roll substrate 12 having an aluminum surface or an aluminum alloy surface, at least one non-traveling industrial robot 20, 22 having robot arms 14, 16 with handling areas P, Q, respectively, for chucking and handling the aluminum hollow roll substrate 12 and transporting it to each processing device 18, and a plurality of the processing devices 18, at least one of which is disposed in each of the handling areas P, Q and performs processing on the transported aluminum hollow roll substrate 12. In the example of Fig. 1, an example is shown in which two industrial robots, the industrial robot 20 and the industrial robot 22, are provided.

[0031] The material of the aluminum hollow roll substrate may be either pure aluminum or aluminum alloy, but aluminum alloy is more preferable in terms of wear resistance. The aluminum hollow roll substrate in the present invention has a surface made of pure aluminum or aluminum alloy. Therefore, for example, an aluminum hollow roll having a copper undercoat plated on its surface, such as the "aluminum hollow roll (plate base material)" used in the examples of Patent Document 2, does not fall under the "aluminum hollow roll substrate" in the present invention.

[0032] The plurality of processing devices 18 include at least two processing devices selected from roll stock devices 24, 26, an aluminum etching processing device 28, a desmutting processing device 30, an electroless zinc plating processing device 32, a nickel plating processing device 34, an alkaline copper plating processing device 36, an acid copper plating processing device 38, and a grindstone polishing device 40.

[0033] In the example of Fig. 1, an aluminum etching treatment device 28, a desmutting treatment device 30, an electroless zinc plating treatment device 32, a nickel plating treatment device 34 or an alkaline copper plating treatment device 36, and an acid copper plating treatment device 38 are arranged in the handling area P of the industrial robot 20. The aluminum etching treatment device 28 is an aluminum degreasing / aluminum etching treatment device that can perform both aluminum degreasing and aluminum etching with one solution. The nickel plating treatment device 34 or the alkaline copper plating treatment device 36 can be the nickel plating treatment device 34 or the alkaline copper plating treatment device 36 by replacing the plating solution depending on the type of strike plating.

[0034] In the example of FIG. 1, the handling area Q of the industrial robot 22 is provided with turntable-type roll stock devices 24, 26, a draining and drying device 42, and a grindstone polishing device 40 (two-head type in the illustrated example). The draining and drying device 42 is equipped with a roll relay table 44 for transferring the aluminum hollow roll substrate 12. The handling areas P of the industrial robot 20 and the handling area Q of the industrial robot 22 overlap on the draining and drying device 42 equipped with the roll relay table 44. In this way, when multiple industrial robots are arranged, it is desirable to provide a roll relay table 44 on any one of the processing devices 18 and configure the handling areas to overlap on any one of the processing devices 18. Note that, in each processing device 18 other than the roll stock devices 24, 26, the devices are provided above and below the same location, making it a two-story device.

[0035] In the example of Fig. 1, it is preferable that the plurality of processing devices 18 further includes a roll cooling processing device for cooling the aluminum hollow roll substrate 12. In the example of Fig. 1, a cooling unit 46 and a cooling water pressurized tank 48 are provided, and the processing device 18 is configured to function as a roll cooling processing device by flowing cooling water therethrough. In the example of Fig. 1, cooling water is passed through the desmutting processing device 30 and the electroless galvanizing processing device 32, so that roll cooling processing can be performed. In other words, the desmutting processing device 30 and the electroless galvanizing processing device 32 are each also roll cooling processing devices.

[0036] Therefore, in FIG. 1, the multiple processing devices 18 are at least two or more processing devices selected from the group consisting of roll stock devices 24, 26, aluminum etching processing device 28, desmutting processing device 30, electroless zinc plating processing device 32, nickel plating processing device 34, alkaline copper plating processing device 36, acid copper plating processing device 38, grindstone polishing device 40, and roll cooling processing device (the desmutting processing device 30 and the electroless zinc plating processing device 32 are provided with this function).

[0037] Desmutting is a process for removing smut that remains on the aluminum surface after etching, such as alloy components that are not dissolved by the etching agent.

[0038] The alkaline copper plating apparatus is a processing apparatus for performing alkaline copper plating using a copper cyanide bath, a copper pyrophosphate bath, or the like.

[0039] The acid copper plating apparatus is a processing apparatus that performs acid copper plating using a copper sulfate bath, a copper fluoroborate bath, or the like.

[0040] In addition, it is preferable that the aluminum alloy surface of the aluminum hollow roll substrate 12 is made of one or more alloys selected from the group consisting of Al-Cu-Mg alloys, Al-Mn alloys, Al-Si alloys, Al-Mg alloys, Al-Mg-Si alloys, and Al-Zn-Mg alloys.

[0041] As the aluminum hollow roll base material 12, as shown in Fig. 4, a flange material 54 having a hollow portion 52 at the center is welded to both ends of a hollow pipe 50. The welded portion 56 is neatly cut by a lathe at the protruding portion caused by welding.

[0042] From the standpoint of strength, an Al-Si alloy is suitable for both the hollow pipe 50 and the flange material 54 .

[0043] An untreated hollow aluminum roll base material 12 is placed on one of the roll stock devices 24, 26, and an aluminum hollow roll base material 12 that has been treated and turned into a plate base material 58 is placed on the other.

[0044] Next, there will be explained a method for manufacturing a plate base material using the plate base material fully automated manufacturing system 10. The plate base material is manufactured as follows.

[0045] The hollow aluminum roll substrate 12 having an aluminum surface or an aluminum alloy surface is placed on the roll stock device 24 (step 100). Then, the hollow aluminum roll substrate 12 is delivered to the industrial robot 22 via the roll transfer stand 44.

[0046] The aluminum hollow roll substrate 12 is transported by the industrial robot 20 and subjected to aluminum etching treatment in the aluminum etching treatment device 28 (step 102).

[0047] The aluminum hollow roll substrate 12 is transported by the industrial robot 20 and subjected to desmutting in the desmutting device 30 (step 104).

[0048] The aluminum hollow roll substrate 12 is transported by the industrial robot 20 and subjected to electroless zinc plating treatment in the electroless zinc plating treatment device 32 (step 106).

[0049] The aluminum hollow roll substrate 12 is transported by the industrial robot 20 and subjected to nickel plating or alkaline copper plating in the nickel plating apparatus 34 or alkaline copper plating (step 108).

[0050] The aluminum hollow roll substrate 12 is transported by the industrial robot 20 and subjected to acid copper plating treatment in the acid copper plating treatment device 38 (step 110).

[0051] The aluminum hollow roll substrate 12 is transported by the industrial robot 20, sent via a roll relay stand 44 to a water draining and drying device 42, where water draining and drying are performed, and then handed over to the industrial robot 22. The aluminum hollow roll substrate 12 is transported by the industrial robot 22, and subjected to grindstone grinding treatment by the grindstone grinding device 40 (step 112).

[0052] In addition, after the treatment steps in the treatment devices, roll cooling treatment is performed in the roll cooling treatment device as necessary. In the illustrated example, the desmutting treatment device 30 also functions as a roll cooling treatment device, so that the roll cooling treatment is performed after the desmutting treatment is performed in the desmutting treatment device 30. In the illustrated example, the electroless galvanizing treatment device 32 also functions as a roll cooling treatment device, so that the roll cooling treatment is performed in the electroless galvanizing treatment device 32.

[0053] After step 114, the aluminum hollow roll base material 12 that has become the plate base material 58 is transferred between the industrial robot 20 and the industrial robot 22, and then transported to and placed on the roll stock device 26. EXAMPLES

[0054] Using the above-mentioned method for manufacturing the plate base material, an aluminum hollow roll substrate having a circumference of 600 mm and a face length of 1100 mm was plated with copper sulfate to a thickness of 60 μm. The aluminum hollow roll substrate was prepared by joining and welding an Al-Si alloy flange material to an Al-Si alloy hollow pipe as shown in FIG. 4. The process was carried out under the conditions shown in Table 2 and in the order shown in Table 1. Example 1 and Example 2 differ in that electrolytic nickel plating was applied in Example 1 and electrolytic alkaline copper plating was applied in Example 2.

[0055] [Table 1]

[0056] [Table 2]

[0057] Comparative Examples 1 and 2 are conventional manufacturing methods for plate base materials, which require an aluminum degreasing process at the beginning. This conventional aluminum degreasing process uses phosphoric acid, but phosphorus is an element whose wastewater concentration is regulated, and its treatment is also time-consuming.

[0058] On the other hand, in Examples 1 and 2, there is an advantage that phosphoric acid is not required and the aluminum etching process can be started. In Examples 1 and 2, plate base materials with high adhesion were obtained more quickly than in the methods shown in Comparative Examples 1 and 2.

[0059] Next, a fully automatic manufacturing system for gravure plate-making rolls according to the present invention will be described with reference to the accompanying drawings. In Fig. 2, reference numeral 60 denotes a fully automatic manufacturing system for gravure plate-making rolls according to the present invention.

[0060] The fully automated gravure plate-making roll manufacturing system 60 is composed of a processing chamber A, a processing chamber B, and a processing chamber C. The processing chambers A and B, and the processing chambers A and C are separated by walls 11 and 13, and are connected to each other via shutters that can be opened and closed.

[0061] The gravure plate-making roll fully automatic manufacturing system 60 is a gravure plate-making roll fully automatic manufacturing system for manufacturing a gravure plate-making roll 86, and is configured to include an aluminum hollow roll substrate 12 having an aluminum surface or an aluminum alloy surface, at least one non-traveling industrial robot 20, 22, 66 equipped with robot arms 14, 16, 62 having handling areas P, Q, R, respectively, for chucking and handling the aluminum hollow roll substrate 12 and transporting it to each processing device 64, and a plurality of the processing devices 64, at least one of which is disposed in each of the handling areas P, Q, R, and for processing the transported aluminum hollow roll substrate 12. In the gravure plate-making roll fully automatic manufacturing system 60, an example in which three industrial robots 20, 22, 66 are used is shown.

[0062] The plurality of processing devices 64 include at least two or more processing devices selected from the group consisting of roll stock devices 24, 26, aluminum etching processing device 28, desmutting processing device 30, electroless zinc plating processing device 32, nickel plating processing device 34, alkaline copper plating processing device 36, acid copper plating processing device 38, photosensitive film coating device 68, electronic engraving device, laser exposure latent image forming device 70, degreasing device 72 (in the illustrated example, an electrolytic degreasing device), grinding wheel polishing device 40, ultrasonic cleaning device 74, developing device 76, etching device 78, resist image removing device 80, surface hardening coating forming device 82, and paper polishing device 84.

[0063] A conventional surface hardening film forming device such as a chrome plating device can be used as the surface hardening film forming device 82. In addition to the chrome plating device, a diamond-like carbon (DLC) film forming device that forms a DLC film, a silicon dioxide film forming device that forms a silicon dioxide film using perhydropolysilazane as a raw material, and the like can also be used. A chrome plating device or a DLC film forming device is preferable. In the example of FIG. 2, an example in which a chrome plating device is arranged is shown.

[0064] 2 shows an example in which an etching device 78, a resist image removing device 80, a developing device 76, a nickel plating device 34 or an alkaline copper plating device 36, and an acid copper plating device 38 are arranged in the handling area P of the industrial robot 20. In addition, the roll relay table 44 is provided above the ultrasonic cleaning device 74, and the handling area P of the industrial robot 20 and the handling area Q of the industrial robot 22 overlap each other above the ultrasonic cleaning device 74 equipped with the roll relay table 44. In addition, the nickel plating device 34 or the alkaline copper plating device 36 can be the nickel plating device 34 or the alkaline copper plating device 36 by replacing the plating solution depending on the type of strike plating.

[0065] 2 shows an example in which turntable-type roll stock devices 24, 26, an ultrasonic cleaning device 74 equipped with a roll relay stand 44, a photosensitive film coating device 68, an electronic engraving device, a laser exposure latent image forming device 70, a grindstone polishing device 40 (two-head type in the illustrated example), and a paper polishing device 84 are arranged in the handling area Q of the industrial robot 22. Note that, for each processing device 64 other than the roll stock devices 24, 26, devices are provided above and below those in the same location, making it a two-story facility.

[0066] In the example of Fig. 2, it is preferable that the plurality of treatment devices 64 includes a roll cooling treatment device for cooling the aluminum hollow roll substrate 12. In the example of Fig. 2, a cooling unit 46 and a cooling water pressurized tank 48 are provided, and the treatment device 64 is configured to function as a roll cooling treatment device by flowing cooling water therethrough. In the example of Fig. 2, cooling water is passed through the desmutting treatment device 30 and the electroless galvanizing treatment device 32, so that roll cooling treatment can be performed. In other words, the desmutting treatment device 30 and the electroless galvanizing treatment device 32 are also roll cooling treatment devices.

[0067] In the example of FIG. 2, the handling area R of the industrial robot 66 is provided with an aluminum etching device 28, a desmutting device 30, an electroless zinc plating device 32, a surface hardening film forming device 82 (a chrome plating device in the illustrated example), and a degreasing device 72 (an electrolytic degreasing device in the illustrated example) equipped with a roll relay stand 88. The degreasing device 72 can also perform electroless silver plating, so it is an electroless silver plating / degreasing device. The aluminum etching device 28 is an aluminum degreasing / aluminum etching device that can perform both aluminum degreasing and aluminum etching with one liquid. The roll relay stand 88 is provided above the degreasing device 72, and the handling area R of the industrial robot 66 and the handling area P of the industrial robot 20 overlap in their handling areas above the degreasing device 72 equipped with the roll relay stand 88.

[0068] Next, a method for manufacturing a gravure plate-making roll using the fully automatic gravure plate-making roll manufacturing system 60 will be described. The gravure plate-making roll is manufactured as follows.

[0069] The hollow aluminum roll substrate 12 having an aluminum surface or an aluminum alloy surface is placed on the roll stock device 24 (step 200). Then, the industrial robot 22 passes the hollow aluminum roll substrate 12 to the industrial robot 20 via the roll transfer stand 44, and the industrial robot 20 passes the hollow aluminum roll substrate 12 to the industrial robot 66 via the roll transfer stand 88.

[0070] The aluminum hollow roll substrate 12 is transported by the industrial robot 66 and subjected to aluminum etching treatment in the aluminum etching treatment device 28 (step 202).

[0071] The aluminum hollow roll substrate 12 is transported by the industrial robot 66 and subjected to desmutting in the desmutting treatment device 30 (step 204).

[0072] The aluminum hollow roll substrate 12 is transported by the industrial robot 66 and subjected to electroless zinc plating treatment in the electroless zinc plating treatment device 32 (step 206).

[0073] The aluminum hollow roll substrate 12 is transported by the industrial robot 66 and handed over to the industrial robot 20 via the roll relay stand 88. The aluminum hollow roll substrate 12 is transported by the industrial robot 20 and subjected to nickel plating treatment or alkaline copper plating treatment in the nickel plating treatment device 34 or the alkaline copper plating treatment device 36 (step 208).

[0074] The aluminum hollow roll substrate 12 is transported by the industrial robot 20 and subjected to acid copper plating treatment in the acid copper plating treatment device 38 (step 210).

[0075] The aluminum hollow roll base material 12 is transported by the industrial robot 20 and handed over to the industrial robot 22 via the roll transfer stand 44. The aluminum hollow roll base material 12 is transported by the industrial robot 22 and subjected to grindstone grinding treatment by the grindstone grinding device 40 (step 210).

[0076] In addition, after the treatment steps in the treatment devices, roll cooling treatment is performed in the roll cooling treatment device as necessary. In the illustrated example, the desmutting treatment device 30 also functions as a roll cooling treatment device, so that the roll cooling treatment is performed after the desmutting treatment is performed in the desmutting treatment device 30. In the illustrated example, the electroless galvanizing treatment device 32 also functions as a roll cooling treatment device, so that the roll cooling treatment is performed in the electroless galvanizing treatment device 32.

[0077] In this manner, a plate base material is manufactured from the aluminum hollow roll substrate 12.
