In situation shown in Figure 1, illustrate such example, promptly, in advance polarizing diaphragm 2 is formed duplexer, be wound into spool body 2A then, but also can be respectively the multiple film etc. that constitutes polarizing diaphragm 2 be formed spool body, pull it successively, use after forming duplexer.The situation that the duplexer that forms polarizing diaphragm 2 is also arranged.Polarizing diaphragm 2 forms and pad 5 cardinal principle same widths described later.
Below, the blanking apparatus 1 of polarizing diaphragm 2 is described.Blanking apparatus 1 with polarizing diaphragm 2 mountings under the state on the above-mentioned pad 5, use stamping-out knife system 7 that its stamping-out is become as needed size of commodity and shape, thereby form polarizing coating 4.In this embodiment, it is the situation of drum that rectangular polarizing diaphragm is rolled into that polarizing diaphragm 2 is shown, but is not limited thereto, for example also applicable to the polarizing diaphragm 2 that uses single sheet, by these polarizing diaphragm 2 stamping-out polarizing coatings 4.
As shown in Figure 1, blanking apparatus 1 has not shown drive unit, and the stamping-out knife system 7 that two ends is wound up into above-mentioned pad 5, the roller 3,3 of the ring type of roller 3,3.Two rollers 3,3 use metal to make in order to have except that the electric work energy.Perhaps, also can consider by conductive processing is implemented on its surface, thereby it is had except that the electric work energy.
Such as shown in Figures 2 and 3, pad 6 is for being a charged plastic sheet that prevents that layer from constituting by the base material 10 of upside (face side of mounting polarizing diaphragm 2) with by the conductive processing layer 11 that apply or evaporation etc. is located at base material 10 lower surfaces.Base material 10 as pad 6 for example preferably uses polystyrene (PS), PETG (PET), polypropylene (PP).As the thickness t 1 of base material 10, for example be set at 500～600 μ m.As the thickness t 1 of conductive processing layer 11, as for can bring into play the charged thickness that prevents function, then the thickness t 1 of also comparable base material 10 is thin.As the roughness of the top 10a of base material 10, promptly surface roughness (JIS B version in 0,601 1994) is preferably Ra:0.01～0.6 μ m (then better as being 0.02～0.1 μ m), Rz:0.1～2 μ m (then better as being 0.2～1 μ m).Ra represents center line average roughness, and Rz represents 10 mean roughness.That is, the surface roughness of base material 10 is compared the value of the even surface that is dead smooth with the surface roughness of former base material 10.
As the material that constitutes conductive processing layer 11, for example can list by metal or indium tin oxides such as aluminium, the evaporation of tin-oxide, the conducting film that sputter obtains, contain from tin, antimony, at least a metal ingredient of selecting in the indium and the alcohol colloidal sol of silicon charged prevents to use the film constituent, by from tin, antimony, the water dispersible colloidal sol of at least a conductive metal oxide of selecting in the indium and water silica sol constitute chargedly prevents to use the film constituent, the hydrolytie polycondensation thing of metal alkoxide, the conjugated system electroconductive polymer, the charged preventor of polymer electrolyte, the materials such as interfacial agent of low molecule-type.
In these charged materials that prevent usefulness, particularly the charged preventor of conjugated system electroconductive polymer, polymer electrolyte can easily form the high conductive processing layer 11 of durability at base material 10 by following method, so, can obtain preferably using.As the concrete example of conjugation electroconductive polymer, preferably use polyaniline, polythiophene, polypyrrole, p-phenylene vinylene or their replacement.They can be coated onto by the electroconductive polymer that will be dissolved in the solubility in the solvent on the base material and to form conductive processing layer 11, or by the directly polymerization and form conductive processing layer 11 on base material 10 of monomer and oxidant.
Concrete example as the charged preventor of polymer electrolyte, preferably use PEO, polyether ester amides, polyetheramides acid imide, oxirane epihalohydrins copolymer, methoxy poly (ethylene glycol) (methyl) acrylate copolymer of nonionic system, (methyl) acrylates copolymer that contains quaternary ammonium group of cation system, contain quaternary ammonium group maleimide copolymer, contain the metering system imide copolymer of quaternary ammonium group, the kayexalate of anion system, the carbonyl betaine-graft copolymer of both sexes class etc.They can be coated onto on the base material after being dissolved into appropriate solvent, or also can with suitable mixed with polymers after carry out melt extruded and form film, be adhered to base material film then.
Above-mentioned stamping-out knife system 7 has supporting station 15, be fixed in the stamping-out cutter of the bottom surface of this supporting station 15 (being also referred to as the Thomsons cutter) but 16, and the not shown up-down drive device that movably supporting station supported of easy on and off.Stamping-out knife system 7 is configured to stamping-out cutter 16 in the reference position position that upper surface (mounting surface) 6a with respect to pad 6 leaves towards the top.Stamping-out cutter 16 forms the shape of the shape that can according to circumstances polarizing diaphragm 2 stamping-outs be become desired.For example, in the situation of this embodiment, forming when observing from the bottom surface is rectangle.
Being configured to of stamping-out cutter 16 supported its supporting station 15 by above-mentioned up-down drive device leaving between position X and the stamping-out position Y, in this X position, the tip-shape point of a knife 17 of stamping-out cutter 16 leaves with respect to the upper surface 6a of pad 6, and this stamping-out position Y makes point of a knife 17 be contacted with the position of pad 6 (entering into the base material 10 of pad 6 in fact slightly) for leave position X decline from this.
Below, illustrate that the stamping-out position 1 of using above-mentioned formation is with the order of polarizing diaphragm 2 stamping-outs one-tenth as needed area of commodity and shape (cutting off the ground stamping-out).Pad 6 synchronously moves towards upstream side C2 from downstream C1 with the driving of roller 3,3, after the upset, from upstream side C2 towards downstream side C1 move, carry out such action repeatedly.Pad 6 upload offset vibrating diaphragm sheet 2 and make its protecting film 23 be in above (diffusion barrier 25 be in below), use is from the suitable mechanisms such as clamping device of width both sides, itself and pad 6 are become one, thereby make pad 6 and polarizing diaphragm 2 synchronously move to downstream C2 from upstream side C1.At this moment, in stamping-out knife system 7, leaving position X, polarizing diaphragm 2 can be inserted between stamping-out cutter 16 and the pad 6.
Polarizing diaphragm 2 one arrive stamping-out knife systems 7 under, then temporarily stop to fill up the driving of 6 drive division, the drive division of the cut-off knife device 7 that liquidates drives, and stamping-out knife system 7 is descended from leaving position X.Like this, the point of a knife 17 of stamping-out cutter 16 enters into polarizing diaphragm 2 from protecting film 23 sides.When stamping-out knife system 7 was further descended, as shown in Figure 4, the point of a knife 17 of stamping-out cutter 16 became the stamping-out position Y that enters into pad 6 slightly.By making stamping-out knife system 7 drop to stamping-out position Y like this, thereby by stamping-out cutter 16 mounting is cut off and stamping-out cutter 16 corresponding area and shapes in the polarizing diaphragm 2 of pad 6, stamping-out becomes polarizing coating 4.Polarizing diaphragm 2 behind the stamping-out batches it at downstream C2, or directly discarded etc., be subjected to suitable processing.
After as described above polarizing diaphragm 2 stamping-outs being become polarizing coating 4, drive the drive division of stamping-out knife system 7 once more, stamping-out knife system 7 is risen, arrive and leave position X.By the intermitten of each such drive division stamping-out polarizing diaphragm 2 successively, thereby make polarizing coating 4 successively.Then, the polarizing coating 4 of stamping-out can for example be piled up and take care of.
In the manufacture process of polarizing coating 4, when stamping-out cutter 16 enters into the synthetic resin layer of polarizing diaphragm 2, easily by the charged state of both friction generation polarizing diaphragms 2, but owing on pad 6, conductive processing layer 11 is located at the lower surface of the base material 10 of upside, so, prevent that by this conductive processing layer 11 polarizing coating 4 is charged.On the other hand, when polarizing diaphragm 2 being carried out stamping-out when it is cut off, mainly produce the dust of synthetic resin from the base material 10 of section, pad 6, but as described above, on pad 6, conductive processing layer 11 is located at the lower surface of the base material 10 of upside, is prevented adhering to of dust, so, dust is not adhered to the polarizing coating 4 of manufacturing, therefore, can make high-quality polarization film 4.
Particularly when stamping-out polarizing coating 4, as the point of a knife 17 of stamping-out cutter 16 become from fill up 6 above 6a enter into the stamping-out position Y of base material 10, from base material 10 dust takes place then easily, but sliding situation flattens on the surface that will fill up 6 base material 10 as described above, even the point of a knife 17 of stamping-out cutter 16 enters into base material 10, compare with the situation of the thicker prior art of the surface roughness of base material 10, its dust generation is also lower.That is, and compared in the past, and can reduce the generation of dust, and can prevent that polarizing coating 4 is charged, so, reduce the generation of dust before comparable, and prevent that by conductive processing layer 11 polarizing coating 4 is charged, so, can prevent positively that dust is attached to polarizing coating 4.
In addition, in this embodiment, make the roller 3,3 of pad 6 of reeling with metal, and it is applied the charged function that prevents, or apply the charged function that prevents on the surface, and, be conductive processing layer 11 with pad 6 sides that are wound up into roller 3,3, the conductive processing layer 11 of pad 6 contacts often with roller 3,3, correspondingly improve the electric energy power of removing, so, can positively prevent adhering to of dust, make high-quality polarization film 4.
, when making polarizing coating 4,, can think that the contact-making surface at pad 6 and polarizing diaphragm 2 also produces small position skew even actuator pad 6 as described above makes the polarizing diaphragm 2 same moved further of mounting in upper surface 6a.In other words, the state of the lower surface 2a friction of the top 6a of the pad 6 of generation driving side and the polarizing diaphragm 2 of slave end, become polarizing diaphragm 2 easy charged states, but owing to be provided with the conductive processing layer 11 that is used to prevent that polarizing coating 4 is charged at pad 6, so, can prevent to fill up the charged of 6 polarizing diaphragms 2 that bring with the position skew of polarizing diaphragm 2, therefore, even as described above in the contact-making surface generation position skew of pad 6 with polarizing diaphragm 2, also can similarly prevent adhering to of dust, obtain high-quality polarization film 4.
In addition, though usually when the state that when roller 2A pulls out polarizing diaphragm 2, becomes easy generation stripping charge, but owing to be provided with conductive processing layer 11 at pad 6, so, as with polarizing diaphragm 2 mountings in the pad 6 on, then stripping charge is removed, this point also can prevent adhering to of dust, so, can make high-quality polarization film 4.In addition, as described above, polarizing diaphragm 2 is not limited to be pre-formed and is drum, and a plurality of films that also will constitute polarizing diaphragm 2 sometimes form independently spool body respectively, on one side mounting is on pad 5 described later, one side forms the duplexer of polarizing diaphragm 2.Yet, even at the state that when each spool body is pulled out film, produces stripping charge,, removing electricity by the conductive processing layer 11 that fills up 6 as overlapped film on pad 6, the result can make high-quality polarization film 4.
Because the surface roughness of the base material 10 of pad 6 forms even surface, so, when the point of a knife 17 of stamping-out cutter 16 from fill up 6 above 6a enter into base material 10 and when forming polarizing coating 4, can prevent effectively that air from entering into 25 of bond layer 24 and diffusion barriers, therefore, light leak can be prevented effectively, high-quality polarization film 4 can be made.
Polarizing diaphragm 2 is from stacking gradually protecting film 23, little bond layer 22, diaphragm 20, polarizing coating 18, diaphragm 21, bond layer 24, reaching diffusion barrier 25.When making stamping-out cutter 16 enter into such polarizing diaphragm 2 from downside, the slurry that then forms bond layer 24 is attached to stamping-out cutter 16, is difficult to obtain smooth section.Yet in this embodiment, making stamping-out cutter 16 is that protecting film 23 sides enter into polarizing diaphragm 2 from the top of polarizing diaphragm 2, cuts off polarizing diaphragm 2 by little bond layer 22.This little bond layer 22 is littler than the thickness of bond layer 24, and bonding force is little, so, compare from the situation that bond layer 24 sides enter with stamping-out cutter 16, can entirely carry out the cut-out (section is smooth) of polarizing diaphragm 2.
The invention is not restricted to above-mentioned embodiment.For example in the above-described embodiment, polarizing coating 4 is for carrying out the situation of stamping-out from polarizing diaphragm 2 each 1 row ground, but be not limited thereto, also can use the polarizing coating 4 wideer corresponding to pad 6 width than the polarizing diaphragm 2 of above-mentioned embodiment, or reduce the external diameter of stamping-out cutter 16, side by side from polarizing diaphragm 2 stamping-out multiple row polarizing coatings 4.
In such situation, it is many that the quantity of the polarizing coating 4 of stamping-out becomes, can think that the amount of dust also correspondingly becomes many, but in embodiments of the present invention, because the face at the pad 6 places pair face opposition side that contacts with stamping-out cutter 16 has carried out conductive processing, so, even the quantitative change of dust is many, can prevent effectively that also its dust is attached to polarizing coating 4, obtain high-quality polarization film 4.
In the blanking apparatus 1 of above-mentioned embodiment, pad 6 is an annular, with polarizing diaphragm 2 mountings thereon, but is not limited thereto.For example also can be used as blanking apparatus, the endless-belt that be wound in roller 3,3 of pad outside 6 is set, rectangular pad 6 is supplied with and carried out mounting to this endless-belt, to pad 6, use 7 pairs of polarizing diaphragms of stamping-out knife system 2 to carry out stamping-out polarizing diaphragm 2 mountings.In such blanking apparatus,, thereby can prevent that dust is attached to polarizing coating 4, can make high-quality polarization film 4 by use and the same pad 6 of above-mentioned embodiment.
