The specific embodiment
Below, describe the preferred embodiments of the invention in detail.Yet the present invention is not limited only to embodiment described herein.
In Fig. 1, in solution casting apparatus 10, on the casting belt 14 that the coating 13 that contains polymer 11 and solvent 12 is in operation from casting head 15 continuous curtain coatings, on casting belt 14, to form casting films 16.By from the dry air that is placed in the drying tube 17 on the casting belt 14 with casting films 16 dryings, solvent gas is from casting films 16 evaporation then.When casting films 16 obtain from-when supporting character, casting films 16 is peeled off from casting belt 14 as wet film 20, and is fed to stenter 21., and on its width, stretch wet film 20 dryings by stenter 21, to obtain film 22.The film 22 that comes out from stenter 21 is fed to drying device 23, and dry.Subsequently, film is reeled from drying device 23 discharges and by up-coiler 24.
The film of producing 22 is that average degree of acetylation is 58.0% to 62.5% cellulose ester membrane, and has 0.3m at least and width, at least 2 μ m and the thickness of 200 μ m and the surface roughness more than the 0.5nm at the most of 3m at the most.
As shown in Figure 2, in drying device 23, be mounted with a lot of Web guide rollers 31, with the continuous film 30 (hereinafter referred to as " tablet ") of guiding continuous feed.Web guide roller 31 constitutes with the roll body 32 of guiding web 30 and the axle 33 that is assemblied in the two ends of roll body 32 by being used to keep.Roll body 32 forms by various technologies (referring to Fig. 3 A to 3E) being applied to aluminium cylinder 35 (hereinafter referred to as " rough pipe (crudetube) ", referring to Fig. 3), so that stable tablet charging ability to be provided.Roll body is not limited to made of aluminum, and can for example iron, stainless steel or carbon fibre reinforced plastic (CFRP) are made by other material.
Following processing technology is applied to roll body 32.As shown in Fig. 3 A, on the outer periphery of rough pipe 35, form nickel coating 36 with predetermined thickness.Then, as shown in Fig. 3 B, on the surface of nickel coating 36, use air blast technology as the bead (not shown) of 0.2mm to 1mm by using average grain diameter.By this air blast technology, the downward recess 41 that in nickel coating 36, has formed a plurality of flanges that make progress 40 and had approximate hemispherical shape.Most overlapped to lower concave part 41, and each overlapping part forms interconnective groove.
Except that nickel, Fe, Cu etc. can be used on pipe 35, electroplating.In addition, in air blast technology, small object for example silica sand and Ceramic Balls can replace bead to use.In addition, downward recess can not only have approximate hemispherical shape, can also have approximate polygon conical in shape.
Secondly, as shown in Fig. 3 C, form a plurality of peripheral groove 42 along the peripheral direction of rough pipe 35 with predetermined spacing by well-known groove formation method.In this embodiment, although each peripheral groove 42 is its bottom triangular grooves for the cross section of sub-elliptical, it can have the cross section of approximate half-circular.
After peripheral groove 42 forms, as shown in Fig. 3 D, on the surface of nickel coating 36, apply the chromium plating of predetermined thickness with flange 40 upwards, downward recess 41 and peripheral groove 42.Thereby, on nickel coating 36, form chromium coating 44.Thereafter, as shown in Fig. 3 E, the surface of polishing chromium coating 44, with removal some parts corresponding to the recessed edge 40 that makes progress in chromium coating 44, thereby at the formation of the position except that downward recess 41 and peripheral groove 42 smooth 46.Glossing is undertaken by using emery cloth or sand paper, polishing wheel etc.Except that chromium plating, can on the surface of nickel coating, use hard material by sprayed ceramic etc.
Carry out these the various technologies shown in Fig. 3 A to 3E, so that following condition to be provided.The mean depth D1 of as shown in Figure 4, downward recess 41 is 0.005mm and 0.5mm at least at the most.If mean depth D1 is less than 0.005mm, then only discharge a spot of when the charging tablet inhaled air, and the tablet confining force reduces.Simultaneously, if mean depth D1 surpasses 0.05mm, then becoming is difficult to form recess.Make thing worse be, when the degree of depth increased, the area of recess became bigger, the result causes the surface to be shifted on the tablet of charging.
Simultaneously, the depth D 2 of peripheral groove 42 is 0.005mm and 1mm at least at the most, and the spacing P between the peripheral groove 42 is 0.1mm and 2mm at least at the most.Because depth D 2 is set to 0.005mm at least, so the inhaled air when the charging tablet of appropriate amount is released, and tablet 30 is kept by suitable confining force.Thereby, on tablet, do not produce for example wrinkle of defective.On the other hand, if depth D 2 greater than 1mm, technology undesirably becomes the difficulty.
The width D 3 of peripheral groove 42 is 0.1mm and 0.5mm at least at the most.Because width D 3 is set at 0.5mm at the most, even treat that the tablet of charging is extremely thin, the defective that does not also occur on the tablet 30 for example shifts and wrinkle on the surface.Simultaneously, if make width D 3 less than 0.1mm, then becoming is difficult to make Web guide roller 31.Can control confining force by the area ratio/occupancy ratio of regulating smooth 46 for tablet 30.In this embodiment, as actual value, the area ratio/occupancy ratio of smooth 46 can and be less than 100% at least 0%, and preferred 40 to 70%.
When satisfying these conditions, to compare with the prior art roller, Web guide roller 31 obtains following advantageous effects.For example, among the prior art roller, the roller that only provides downward recess 41 has shown tablet charging rate dependence, and when quickening to be used for the charging rate of tablet 30, can not discharge enough air that has been inhaled in the charging of tablet.Therefore, the confining force to tablet 30 reduces.In contrast to this, even when quickening the charging rate of tablet 30, Web guide roller 31 of the present invention also can discharge the air that can not only fully discharge by downward recess 41 by peripheral groove 42.Therefore, the tablet confining force of Web guide roller 31 can remain unchanged, no matter and the acceleration of tablet charging rate.Therefore, charging tablet 30, and not slippage on Web guide roller 31.
In Fig. 5, curve Figure 50 shows the tablet confining force of the of the present invention Web guide roller 31 relative with the charging rate of tablet 30.Simultaneously, curve Figure 51 shows the tablet confining force of the roller that only have downward recess (hereinafter referred to as " conventional Web guide roller ") relative with the charging rate of tablet 30.Wherein, Web guide roller 31 of the present invention and conventional Web guide roller have the area ratio/occupancy ratio of identical smooth.As shown in curve Figure 50 and 51, when the charging rate of tablet 30 is hanged down (for example charging rate S), the tablet confining force of Web guide roller 31 and conventional Web guide roller is approximately identical.When quickening the charging rate of tablet 30, the tablet confining force of conventional Web guide roller reduces rapidly, and the tablet confining force of Web guide roller 31 maintains constant value, and does not reduce.Therefore, the speed dependence of tablet confining force is ineffective for Web guide roller 31 of the present invention, and even when with high speed charging tablet 30, also can guarantee to keep and guiding webs 30 by Web guide roller 31.
In the present embodiment,, also the present invention can be applied to the equipment Web guide roller in the stenter for example that is placed in other although described Web guide roller in the drying device that is placed in solution casting apparatus.The present invention can be applied to and not only be placed in solution casting apparatus, and be placed in Web guide roller in other the production equipment.
In this embodiment, although with continuous cellulose acylate film as tablet, can also use flexible belt-sample material, or the band sample object that this flexible belt-sample material is used as base material and has machined layer thereon.Flexible belt-sample material is made by following material: plastic foil, for example PETG, polyethylene-2,6-naphthalate, polyvinyl chloride, poly-inclined to one side vinylidene chloride, Merlon, polyimides, polyamide etc.; Paper; Coating or lamination have the α-polyolefin paper of polyethylene, polypropylene and ethylene-butene copolymer for example with 2 to 10 carbon numbers; And metal forming, for example aluminium, copper and tin.
