Description
Technical field
The present invention relates to the method for winding of thin polymer film and the cold roller that is adopted.
Background technology
Acylated cellulose film, particularly acetyl cellulose film are widely used on electronic console purposes, photo support purposes, other optical applications.Particularly, along with the development rapidly of electronic console purposes, more and more require its filming in recent years, need further increase productivity for these films.
Acylated cellulose film is made by solution casting method usually.In this solution casting method; acylated cellulose and plasticizer, UV absorbent, lubricant and other additives together be dissolved in make thick solution in the solvent; make then this thick solution from the mould curtain coating on annular supports such as band (band), cylinder; and solution is solidified solvent seasoning; peel off from supporter then, further make film after the drying.
Along with the acceleration day by day of speed of production, in product coiling portion, because air related is difficult to carry out stable coiling.Because being involved in of related air, the difference that the diameter up and down of film roll can take place becomes big fault (below, be referred to as loose coiling) or the fault (below, be referred to as depression) of hollow takes place on the top of film roll.Speed of production is fast more, film thickness is thin more, and this fault takes place more significantly.
As the method for getting rid of this related air, when coiled film, utilize cold roller (レ イ オ Application ロ-Le) to volume core side extrusion film.(for example, with reference to patent documentation 1).By this method, can be formed on the film roll that has uniform air layer thickness between the pellicular front.
[patent documentation 1]
The spy opens 2002-68535 communique (the 2nd page~the 4th page)
But if use cold roller, then by the contacting and peeling off of film and cold roller, wound film can be charged, and inhale by electrostatic interaction and poly-ly to swim in airborne impurity, and become the reason of impurity fault.In addition, as the method for electrically that removes of film, what adopt at present is, remove electrical equipment generation ion with the formula of adding, and this ion and roller shape film as product are bumped against, thereby remove the method for electricity, but in this mode, cause the deterioration of the rubber on cold roller surface reeling indoor generation ozone.Thus, the volume resistance of rubber surface increases, and electrification phenomenon is more serious.And the hardness of rubber uprises, the substrate deformation fault that has occurred the underworld shape on the circumferencial direction of film roll (below, be called the black-tape fault).
Summary of the invention
The present invention proposes in order to address the above problem, it is charged that its purpose is taken place by peeling off of cold roller when being to be suppressed at coiled film, do not have the thin polymer film of impurity fault simultaneously with high-quality manufacturing with the coiling stable posture that makes film roll when the high-speed production.
In order to achieve the above object, among the present invention,, be 10 by using specific insulation as the surface material of cold roller
2Ω cm above 10
12Following and the hardness of Ω cm is the following rubber of above 70 degree of 30 degree, prevents the charged of film.
In addition,, can prevent the deterioration of surface material, also can prevent charged or black-tape fault by the material of ozone resistance excellence being used as the surface material of described cold roller.
In addition, the winding speed of described film preferably divides below the above 200m/ branch at 30m/, more preferably divides below the above 100m/ branch at 30m/.In addition, the thickness the during coiling of described film is preferably below 125 μ m more than the 20 μ m, more preferably below 85 μ m more than the 20 μ m.In addition, the thrust of the described cold roller the during coiling of described film is preferably below the above 100N of 10N.Also have, described thin polymer film is preferably acylated cellulose film.

Among the figure, 11-thin polymer film, 12-film roll, the cold roller of 13-, 13b-surface material
The specific embodiment
Fig. 1 is the scheme drawing of the winding film portion of the embodiment of the invention.Volume core 10 is set on the winding film machine, and is driven by not shown motor drives rotation.Thus, thin polymer film 11 is wound onto on the volume core 10 gradually, becomes film roll 12.
Cold roller 13 is installed into and rotates freely, so that itself and film roll 12 limit contact edges rotate.This cold roller 13 constitutes by hold-down mechanism 14, to volume core 10 side compression thin polymer films 11.Thus, when thin polymer film 11 is reeled, the air that film 11 carries can be got rid of, the film roll 12 that has uniform air layer thickness between the film can be formed on.
As shown in Figure 2, cold roller 13 is to cover the NBR rubber of (lining) ozone resistance excellence to constitute as surface material 13b on the surface of metallic roller main body 13a such as SS, SUS.In this surface material 13b, add additive etc. and adjust, so that its hardness for example is that 40 degree, specific insulation are 10
8Ω cm.As roller, there is Co., Ltd. to add and passes through the white EC240NS that roller is made manufacturing with this surface material 13b.In addition, the mensuration of hardness is to carry out according to JIS K6253, and the mensuration of specific insulation is to carry out according to JIS K6271.
As the surface material 13b of cold roller 13, preferably use specific insulation 10
2Ω cm above 10
12Below the Ω cm, more preferably use 10
4Ω cm above 10
8Below the Ω cm.In addition, preferably using hardness is below 30 degree above 60 are spent, and more preferably uses below above 50 degree of 35 degree.In addition, the surface material 13b of cold roller 13 preferably uses the material of ozone resistance excellence.
In addition, the winding speed of thin polymer film 11 is preferably more than the 30m/ branch.And the thickness when the coiling of thin polymer film 11 is under the situation below the 125 μ m, and the low especially easy deformation of membrane rigidity is so effect of the present invention is remarkable, preferred.More preferably below 85 μ m, particularly preferably be below 65 μ m.In addition, the thrust of the cold roller 13 during coiling thin polymer film 11 is desirable below the above 80N of 20N.Be more preferably below the above 60N of 30N.In addition, the coil diameter variation according to film roll 12 is changed to preferably the thrust of cold roller 13 continuously in the scope of 60N to 30N.
There is no particular limitation for the shape of cold roller 13, also can use the cold roller 13 of tapering portion.At this moment, act on thrust on the contact surface of thin polymer film 11 and cold roller 13 preferably below the above 60N of 30N.
In addition, be applicable to that the material of the film among the present invention has no particular limits, for example can use cellulose acetates such as cellulose triacetate, the plastic sheeting of polyester such as polyethylene terephthalate, PEN etc. etc.As product and the wound film roller, its width is about 600~3500mm, is generally about 1000~1600mm, thickness is about 25~250 μ m, be generally about 30~100 μ m, coiling length is about 500~10000m, is generally about 2000~6000m.
In addition, two ears (both side ends) at the thin polymer film of reeling are formed with the embossing (knurling) that is made of projection or recess etc. as everyone knows, and the shape of this embossing also has no particular limits, and can use different shape.
