Description
Technical field
The present invention relates to rectangular air blocking thin film is cut off, make the air blocking thin film manufacturing approach of the air blocking thin film of section (cut sheet) shape.
Background technology
For the employed packaging material of packing of the position that is asked to moisture resistance in the various devices such as display unit such as optical element, LCD or OLED display, semiconductor device, thin-film solar cells or parts, food, dress material, electronic unit etc., utilized at plastic sheetings (supporting mass) such as PETG (PET) films to be formed with the air blocking thin film that film (choke film) that (film forming) present gas barrier property forms.
As the choke film that forms air blocking thin film, the known film that has by various inorganic compounds (inorganic matter) such as silicon nitride, silica, aluminium oxide formation.
Here, as also putting down in writing in the patent documentation 1, these choke film-strengths are low, because of contact is destroyed easily.In addition, because the choke film breaks etc., so the choke film generally is the film that approaches if surpass then hardening of 300nm easily.
As can be with the method for the such air blocking thin film of good production efficiency manufacturing; Known have a kind of use that rectangular supporting mass (supporting mass of web-like (substrate/base material)) is wound into the donor rollers that the roller shape forms; Supporting mass to seeing off from donor rollers carries out film forming, and the supporting mass that film forming finishes is wound into the so-called volume to volume (Roll to Roll) of roller shape once more.
In film forming based on this volume to volume; Supporting mass is carried out the prescribed path of the film forming room of film forming in process; Carry out synchronously rectangular supporting mass from donor rollers paper feed (insert logical) to winding roller and from donor rollers to supporting mass see off and winding roller to the finish winding of supporting mass of film forming, and the while in film forming room, the supporting mass that is handled upside down is carried out film forming continuously.

Air blocking thin film is used as the section use of given size under most situation.Therefore, the air blocking thin film that has formed the choke film through volume to volume need be cut off the section that (severing processing) becomes given size.
As the method that rectangular tablet is formed the section of given size; The preferred utilization through 1 procedure; With desirable size and at the point of the section that can access desirable shape etc., use so-called punching press (molding) with the identical shaped frame shape sword of the section that becomes purpose.
Here, as stated, because the choke film is the film that is made up of inorganic compound, so be harder, crisp film.And as also putting down in writing in the patent documentation 1, the choke film causes breaking more easily if thickening then loses flexibility.
And if become the thickness of a certain degree, even if then make the further thickening of choke film, gas barrier properties can not improve yet.This is because as far as the choke film, by the compactness decision gas barrier properties of the molecule that forms film.Therefore, after having formed certain film more than certain, the character on the thickness direction do not change.But, if choke film thickening, the embedding property of the inorganic substances of the external disturbances as foreign matter of then relatively sneaking into during film forming also improves.But, under this situation, because the easy degree of breaking becomes the mastery factor, so the result causes performance to reduce.Therefore, as stated, the choke film that forms air blocking thin film generally is the film that approaches.
If the rectangular air blocking thin film that will have such choke film through punching press etc. cuts into the section of regulation shape, then because the power that applies when cutting off, the choke film is cracked or break, cause the choke film to be destroyed.As a result, gas barrier properties significantly reduces.
And the destruction of this choke film is not only at mould (die) or push (give as security さ え) directly problem of producing of periphery of contact.That is, if air blocking thin film is cut to the section of regulation shape through punching press etc., then fully away from the position that does not contact of cut-out portion with punch die, power also can be propagated as vibrating, and this problem of defective that the destruction because of barrier film causes can take place.
In addition,,, then destroy the choke film easily, also can cause gas barrier properties significantly to reduce if in the various operations of cutting off before finishing and become the section shape, contact with the choke film as also putting down in writing in the patent documentation 1.

Special when inorganic layer 16 is blocked up, owing to destroy easily during cut-out, so, can prevent better can obtain desirable result because of cut-out causes the destruction to inorganic layer 16 through thickness being made as above-mentioned scope.
The manufacturing approach of air blocking thin film of the present invention is used for the film roll that forms from so rectangular air blocking thin film is wound into the roller shape, draws air blocking thin film and with its cut-out (severing processing), makes it become the section shape air blocking thin film of given size.
Particularly, draw rectangular air blocking thin film, at first it is cut off, as the billet air blocking thin film of the length corresponding with the section shape air blocking thin film that will make at width (with the direction of length direction (the drawing direction) quadrature of rectangular air blocking thin film) from film roll.In manufacturing approach of the present invention, the both ends with the width of this billet air blocking thin film cut off at length direction subsequently, cut the both ends of width, become the section shape air blocking thin film of given size (regulation shape).
Wherein, Width both ends after the cut-out through width becomes the billet air blocking thin film are in the cut-out of length direction, and width and length direction are width and the length directions (following simply be called " width " and " length direction ") that is cut under the billet rectangular state before.
Fig. 2 (A) and Fig. 2 (B) have schematically shown the example that width cuts off.
In this example, at first, draw rectangular film L to 24 through 2 carrying rollers from rectangular air blocking thin film L (following be called for convenience's sake rectangular film L) is wound into the film roll 20 that the roller shape forms.
On one side through the carrying roller to 24 length direction (=draw direction) carryings that this rectangular film L that draws is represented with arrow a in figure, Yi Bian utilize rotary cutter 28 (omission in Fig. 2 (B)) it to be cut off at width.Through the cut-out of this width, form the billet air blocking thin film S corresponding (the following billet film S that is called for convenience's sake) with the length of the section that will make.
In example shown in Figure 2, the parts that the rectangular film L (being cut billet film S) before the downstream (downstream of drawing direction of=rectangular film L are designated hereinafter simply as downstream) of the carrying direction of rotary cutter 28 do not dispose and cut off contacts.That is the position that the cut-out line that, forms than rotating knife head 28 relies on the downstream becomes free end.
Therefore, fallen by the guide 30 of slide unit shape (in Fig. 2 (B), omitting) guiding through rectangular film L being cut off the billet film S that processes at width, quilt is to the sever supply at the both ends of ensuing width.
Wherein, preferred such rectangular film L carries out with regional contact of non-goods of cut width end afterwards to the paper feed (logical paper) of the shearing device of width.
In example shown in Figure 2, rotary cutter 28 is the peripheries at the cylindric rotary body 28a with rotating shaft consistent with width (center line), has the known rotary cutter of the sword 28b of broad ways extension.Wherein, the Reference numeral 32 among Fig. 2 (A) is supporting station (following swords/knife-edge bearing thing).
Here, in example shown in Figure 2, as an example, rectangular air blocking thin film L is handled upside down through choke film top in figure is drawn.
As stated, rectangular film L is drawn from film roll 20 24 through 2 carrying rollers, is being cut off in the carrying along its length.The carrying roller to 24 in, with the roller 24b of the supporting mass Z butt of downside be common cylindrical roller.Relative therewith, the carrying roller to 24 with figure in the roller of choke film butt of top be the diameter big so-called ladder roller 24a of the diameter of end (perhaps) than its zone (middle section) in addition the end near.
In addition, ladder roller 24a only with the regional butt both ends of the width of rectangular film L, that in the cut-out at the width both ends of back, cut.That is, ladder roller 24a only with the non-goods zone butt of rectangular film L.
In air blocking thin film, choke film 12 or in the choke film of cascade type, embody inorganic layer 16 thin and fragiles of gas barrier property.Therefore, if the direct and choke film butt of carrying roller equity parts then can crack, break on the choke film (inorganic layer 16) of this part mostly.And, unnecessarily contact also the situation that expectation anything but takes place with the goods zone of choke film, become a factor that produces incorrect goods.
Relative therewith; Through as illustrated example, employing will with the roller of choke film butt as ladder roller 24, only with the formation of the non-goods zone butt that is cut afterwards; Can prevent destruction and the damage etc. of the choke film in goods zones reliably, thereby stably make appropriate goods.
As stated, in manufacturing approach of the present invention, rectangular film L broad ways is cut off, carried out the cut-out at width both ends then.Fig. 3 (A) and Fig. 3 (B) have schematically shown an one of which example.
In this example, utilize tape-cutting machine (slitter) 40 both ends (arrow a direction) cut-out along its length with the width of billet film S, form the section shape air blocking thin film C (the following goods film C that is called for convenience's sake) of given size.
Tape-cutting machine 40 is as shown in Figure 3; Be to be configured the off-position shown in the dotted line in the drawings, to have the rotating shaft (i.e. rotation along its length) of width and through billet film S being cut off by 2 circles (discoid) rotation sword 40a (going up sword and following sword) that is clamped in thickness direction (above-below direction), the known tape-cutting machine that cuts off the end of the width of billet film S along its length.In illustrated example, as preferred mode, the off-position at the both ends of the width of billet film S disposes the tape-cutting machine 40 of the co-located that is positioned at length direction respectively, and the both ends of billet film S are cut off simultaneously.
Can move tape-cutting machine 40 by the cut-out of these tape-cutting machine 40 realizations and carry out, also can carry billet film S and carry out, both are relatively moved carry out.In addition, since billet film S till this tape-cutting machine 40 carrying and carry out with being contacted for the carrying that utilizes the billet film S that tape-cutting machine cuts off by the width both ends of tape-cutting machine 40 cut-outs.
Here, in manufacturing approach of the present invention, the air blocking thin film that with the air blocking thin film of a side of cutting off the line quadrature, promptly clips a side of cutting off line is not carried out the cut-out of the air blocking thin film of width and length direction with keeping.Perhaps, in manufacturing approach of the present invention,, carry out the cut-out of the air blocking thin film of width and length direction through the shut-off mechanism that contacts with air blocking thin film point.
Particularly; Being breaking at of the width of rectangular film L do not contrast under the situation that air blocking thin film that off-position relies on the downstream of drawing direction of rectangular film L implements to push and cuts off; Perhaps, cut off through the shut-off mechanism that contacts with the air blocking thin film point that will cut off.
In illustrative example; When broad ways is cut off rectangular film L; The off-position of not representing with chain-dotted line in the comparison diagram 2 (B) is leaned on air blocking thin film that the quilt in downstream (right side among the figure) cuts, is promptly become that the part of billet film S keeps; Utilize rotary cutter 28 that rectangular film L is cut off, form billet film S.In other words, in illustrated example, be made as state (becoming free-ended state) freely, carry out the cut-out of width with the part that will become billet film S.
In addition; The zone that being breaking at of the both ends of the width of billet film S not to the opposition side of cut end, promptly becomes goods film C is implemented to push under the situation of (becoming state freely) and is cut off; Perhaps, utilize the shut-off mechanism that contacts with the air blocking thin film point that will cut off to cut off.
In illustrated example, through having the tape-cutting machines 40 of contact with billet film S point 2 pieces rotation sword 40a, the both ends of billet film S are cut off along its length, form the goods film C of given size.
And, in the present invention, in that rectangular film L broad ways is cut off after forming billet film S, the width both ends of billet film S are cut off along its length, form given size section shape air blocking thin film, be goods film C.
Manufacturing approach of the present invention is through having such formation; Rectangular film L is being cut off; When making the section shape goods film C of given size (regulation shape), the destruction that can prevent the choke film rightly, thus stably make the air blocking thin film that embodies the regulation gas barrier property.
Rectangular tympan is being cut off; During the section shape tympan of the given size that manufacturing cuts 4 limits (following also abbreviate as section); Owing to can obtain the section of desirable size and shape through an operation, general using adopts the so-called punching press of cutting off with the corresponding frame shape sword in 4 limits of section (molding).
But; Research according to the present inventor; If will form the air blocking thin film cut-out that the choke film forms on the surface of supporting mass Z through punching press; Then can on choke film (under the situation of cascade type such shown in Fig. 1 (B), (C), being the inorganic layer 16 that embodies gas barrier property), crack, break, cause the choke film to be destroyed.In addition, this crackle, break near cut-out portion, also extend to form near the center of section shape air blocking thin film.
Present inventors study the destruction reason of this choke film in detail.The result draws following conclusion: chief reason is when cutting off, choke film (inorganic layer 16) have been applied power, and this power causes the choke film to be destroyed to transferring with the direction of cutting direction quadrature thus.
And the method for the destruction of the choke film when preventing this cut-out has been carried out research repeatedly, and the result draws following conclusion: through when cutting off not to implementing to cut off with the air blocking thin film of a side of cutting off the line quadrature with pushing, can prevent this destruction.In other words, through cutting off as free end (discharging end), can prevent to cut off the destruction that the choke film is caused with at least one side of the direction of cutting off the line quadrature.In addition, use as tape-cutting machine 40, contact the shut-off mechanism that cuts off with air blocking thin film point, also can prevent because of cutting off destruction to the choke film.
The present inventor has carried out research and experiment repeatedly to the cut-out processing of air blocking thin film, and the result finds when being cut off, and except section, also is corrupted to the phenomenon of inboard goods portion.Its reason is that the inoranic membrane (inorganic layer 16) that forms the choke film is not the such chemical bond key of organic film, but only combines with molecular separating force by each molecule.That is, the combination of this inoranic membrane is compared with organic film, and the density of film inside is bigger, when having applied certain power (under the situation of propagation), is basic point with sparse part easily, and continuous or some wire ground propagation destroys.Therefore, if as severing, section is applied very large power, and masterpiece is used in the face of film whole, then constantly broken along weak part (as crackle breaks).
The present inventor considers the characteristic of such inoranic membrane, thinks that when the air blocking thin film that on supporting mass Z, has formed the choke film was carried out severing, importantly power did not apply to the goods regional integration of film in order to prevent the destruction of this choke film.Promptly; Through under the situation of not pushing cut air blocking thin film; One side is cut off as freely bringing in; Thereby film integral is moved alleviate the power that air blocking thin film applied when cutting off, stretching force through pushing the stress that applies and stretching to the direction of sword when cutting off through free end is set, and can prevent the choke film is applied unnecessary power, the result can prevent the destruction of choke film.
In addition, under the situation of the shut-off mechanism that adopts the some contact, because the power that acts on any disperses to air blocking thin film is whole, so be applied in the power as the choke film takes place to destroy also can prevent to cut off the time.
Therefore, the present invention according to cutting off under not to the situation of implementing to push with the air blocking thin film of a side of cutting off the line quadrature can prevent to cause the destruction to the choke film because of cut-out well.
Here,, consider the simplification of processing and operation, at first carry out the cut-out of the length direction of end usually, carry out the cut-out of width then so rectangular tympan broad ways and length direction being cut off, formed under the situation of section.
That is, through carrying out the cut-out of width at last, tympan is handled as an object till can be to the end.For example, if example shown in Figure 2 then through between the carrying roller is to 24, disposing tape-cutting machine 40 as shown in figure 3, can carry out the width end to the cut-out of length direction and the cut-out of width continuously, rectangular tympan is formed section.
But; In the air blocking thin film that the surface of supporting mass formation choke film forms; If cut off the goods film C that makes the section shape in proper order with this; Then after the both ends of width are cut off, because the cut-out of carrying, width, can cause carrying parts such as roller need contact with the zone of the goods that become air blocking thin film.In addition, the width end to the cut-out of length direction, and the cut-out of width between, when needing operation that paper feed operation, transport operation etc. undertake by the operator, also need contact with the zone that becomes goods.
As stated, choke film (being inorganic layer 16 under the situation of cascade type) thin and fragile.Therefore,, then can cause the choke film to crack, break, make the choke film be destroyed if the part that is contacted does not apply local power.
Relative therewith, in manufacturing approach of the present invention,, carry out the cut-out at the both ends of width then through at first carrying out the cut-out of width, can be before becoming goods film C, residual always non-goods zone.
Thus, the ladder roller through utilizing that kind shown in Figure 2 etc. can not contact with the goods zone before becoming goods film C, and carried out the operations such as carrying, cut-out of rectangular film L contiguously with non-goods zone.Therefore, can prevent the damage of the choke film in the goods zone well, carry out the operations such as cut-out of the width of the carrying of rectangular film L, rectangular film L simultaneously reliably.In addition, when needing the operator to touch air blocking thin film because of paper feed, carrying etc., owing to after can touching operation is carried out in the non-goods zone at cut width both ends, so can prevent the damage of the choke film in the goods zone equally.
Therefore; According to rectangular film L broad ways is cut off; Cut off the both ends of width then; And the present invention who under the situation of air blocking thin film not being implemented to push, cuts off or utilizes the shut-off mechanism based on a contact to cut off can stably make the air blocking thin film of the given size (regulation shape) destruction, embodiment regulation gas barrier property that has significantly suppressed the choke film.
In addition, in the present invention, if above-mentioned condition is satisfied in the cut-out at the cut-out of width and width both ends, the processing beyond then as long as with the cut-out (severing operation) of common air blocking thin film equally.
In addition, the present invention is not limited to utilize rotary cutter 28 to carry out the cut-out of width, utilizes tape-cutting machine 40 to carry out the cut-out at width both ends.And; The tape-cutting machine that cuts off based on a contact is not limited to the tape-cutting machine of cutting off type 40 that adopts 2 pieces of rotation sword 40a; Also can utilize the circle that adopts upside (choke film side) to rotate the knife-edge bearing body of sword and downside, clamp the tape-cutting machine of the cut-out type of billet film S by both along thickness direction.
In manufacturing approach of the present invention, for example also can not contrast the cut-out line and push, and carry out the cut-out of the width of rectangular film L through so-called cutting machine (guillotine cutter) by the downstream.Perhaps, also can use the discoid rotation sword that contacts with rectangular film L point, carry out the cut-out of the width of rectangular film L.
But, under this situation, need stop to carry the cut-out of carrying out rectangular film L.That is, need carry out the carrying of rectangular film L intermittently.Therefore, the shearing length of billet film S is easy to generate error, and, owing to carry repeatedly/stop, can cause burden to rectangular film L (air blocking thin film), damage the possibility of air blocking thin film in addition.And owing to carry out interrupted carrying, production efficiency also significantly reduces.
Therefore, the cut-out of the width of rectangular film L is preferably adopted as the rotary cutter 28 of illustrated example, the shut-off mechanism that can in the rectangular film L of carrying, cut off.
In addition, the present invention is not limited to utilize corresponding 2 tape-cutting machines 40 that are configured in the co-located of length direction with both ends, the equipment that the two ends of width are cut off simultaneously.For example, the cut-out at the both ends of width also can be carried out the cut-out of width end to each end through tape-cutting machine successively, thereby forms goods film C.At this moment, the configuration that can the allocation position of 2 tape-cutting machines be offsetted is along its length carried out the cut-out of end continuously by end ground, also can utilize a tape-cutting machine to carry out the cut-out of width end by end ground.
Perhaps, can utilize cutting machine to pursue end ground and carry out the cut-out at the both ends of width successively, thereby form goods film C.And, also can utilize rotary cutter to carry out the cut-out of the end of width successively the carrying of billet film S broad ways, thereby form goods film C.And, in the cut-out at the both ends of width, can utilize tape-cutting machine with the mode that the other end cuts off according to utilizing cutting machine that one end-grain cutting is disconnected, use different shut-off mechanisms.
At this moment, the area side that becomes goods is not implemented to carry out the cut-out of billet film S with pushing.
Promptly; In manufacturing approach of the present invention; No matter under what kind of situation, for the destruction of the choke film that prevents to become goods, when needs during by operator or device contact billet film S; All preferably do not contact with the zone that becomes goods zone (goods film C), and with cut width end is contacted.
More than, the manufacturing approach of air blocking thin film of the present invention is illustrated in detail, but the present invention is not limited to above-mentioned example, in the scope that does not break away from purport of the present invention, certainly carries out various improvement and change.
For example, in Fig. 2, can replace and use the carrying roller of ladder roller right, and use the clip that cut part is controlled at the width both ends, carry out the carrying of rectangular film L.Perhaps, in rectangular film L, can cut part be formed locating hole (sprocket hole), utilize the gear (sprocket gear) that engages with this locating hole to carry out the carrying of rectangular film L at the width both ends.
In addition; The section shape air blocking thin film of manufacturing of the present invention is not limited to rectangles such as square or rectangular; Also can utilize shape with curvilinear limit etc., rectangular tablet broad ways is cut off, then the width both ends cut off the different shape that forms along its length.
