Description

刃型、該刃型を用いたフィルムの打ち抜き方法、および該刃型を備える打ち抜き装置Blade mold, film punching method using the blade mold, and punching apparatus equipped with the blade mold

　従来より、フィルム製品の製造においては、大面積で得られたマザーフィルムから、用途に応じた形状のフィルム製品を打ち抜くことが行われている。一般に、マザーフィルムを打ち抜く際には、所定の打ち抜き刃を備える刃型が用いられている。しかしながら、打ち抜き時、打ち抜き刃からフィルムにかかる力は必ずしも均一とはならず、不均一な力が製品にかかった場合、フィルム製品がダメージ（例えば、押し跡、フィルム製品が積層体の場合の剥離等）を受けることがある。特に、偏光板等の光学フィルムの打ち抜きにおいては、上記の問題が顕著となる。 Conventionally, in the manufacture of a film product, a film product having a shape corresponding to the application is punched from a mother film obtained in a large area. Generally, when punching out a mother film, a blade mold having a predetermined punching blade is used. However, at the time of punching, the force applied to the film from the punching blade is not necessarily uniform, and if the non-uniform force is applied to the product, the film product may be damaged (for example, imprint, peeling when the film product is a laminate) Etc.). In particular, in the punching of an optical film such as a polarizing plate, the above problem becomes significant.

Ａ．刃型
　図１は、本発明の１つの実施形態による刃型の概略平面図である。刃型１００は、打ち抜き刃１０と、副刃２０とを備える。打ち抜き刃１０は、閉じた平面視形状を有する。刃型１００を用いてフィルムを打ち抜く際には、打ち抜き刃１０によりフィルムが打ち抜かれる。副刃２０は、打ち抜き刃１０の外側に設けられる。１つの実施形態においては、副刃２０は、打ち抜き刃１０に沿うようにして設けられる。図１では、打ち抜き刃と副刃とから構成されるセットを１セットのみ備える刃型を示しているが、本発明の刃型は、図２に示すように、打ち抜き刃と副刃とから構成されるセットを複数セット備えていてもよい。なお、打ち抜き刃と副刃とから構成されるセットを１セット用いれば、１片のフィルム片を打ち抜くことができる。 A. Blade Type FIG. 1 is a schematic plan view of a blade type according to one embodiment of the present invention. The blade mold 100 includes a punching blade 10 and a sub blade 20. The punching blade 10 has a closed plan view shape. When a film is punched using the blade mold 100, the film is punched by the punching blade 10. The auxiliary blade 20 is provided outside the punching blade 10. In one embodiment, the secondary blade 20 is provided along the punching blade 10. Although FIG. 1 shows a blade mold having only one set composed of a punching blade and a secondary blade, the blade mold of the present invention is composed of a punching blade and a secondary blade as shown in FIG. A plurality of sets may be provided. If one set consisting of a punching blade and a sub-blade is used, one piece of film can be punched.
　本発明の刃型を用いてフィルムを打ち抜く場合、フィルムが打ち抜き刃に接した時点ではフィルムに所定の力がかかり、さらに打ち抜き刃をフィルムに押しつけて（または、フィルムを打ち抜き刃に押しつけて）、フィルムを打ち抜く際には、該フィルムに接する副刃の作用によりフィルムにかかる力が分散される。その結果、フィルムのダメージが低減され、押し跡等が防止された打ち抜きフィルムが得られ得る。また、フィルムが積層体の場合には、該フィルムの層間剥離が防止され得る。以下、便宜上、フィルムが打ち抜き刃に接した時点を接触時点といい、接触時点からさらに刃型をフィルムに押しつけた時点（または、フィルムを刃型に押しつけた時点）を打ち抜き時点ということもある。なお、フィルムは、打ち抜き時点で切断される。 When punching a film using the blade mold of the present invention, when the film comes into contact with the punching blade, a predetermined force is applied to the film, and further pressing the punching blade against the film (or pressing the film against the punching blade) When punching out the film, the force applied to the film is dispersed by the action of the secondary blade in contact with the film. As a result, it is possible to obtain a punched film in which damage to the film is reduced and imprinting is prevented. Moreover, when a film is a laminated body, delamination of this film can be prevented. Hereinafter, for the sake of convenience, the time when the film contacts the punching blade is referred to as the contact time, and the time when the blade mold is further pressed against the film from the contact time (or the time when the film is pressed against the blade mold) is sometimes referred to as the punching time. The film is cut at the time of punching.
　上記打ち抜き刃および副刃としては、任意の適切な刃物が用いられ得る。打ち抜き刃および副刃に用いられる刃物としては、例えば、トムソン刃、腐食刃、彫刻刃等が挙げられる。 Any appropriate blade can be used as the punching blade and the auxiliary blade. Examples of the cutter used for the punching blade and the auxiliary blade include a Thomson blade, a corroding blade, and an engraving blade.
　上記の打ち抜き刃の平面視形状は、任意の適切な形状であり得る。打ち抜き刃の平面視形状としては、例えば、略正方形状、略長方形状、略円形状、略楕円形状等挙げられる。また、打ち抜き刃の平面視形状は、直線と曲線とを適宜組み合わせた形状、曲率の異なる複数の曲線から構成された形状であってもよい。 The plan view shape of the punching blade may be any appropriate shape. Examples of the plan view shape of the punching blade include a substantially square shape, a substantially rectangular shape, a substantially circular shape, and a substantially elliptical shape. In addition, the plan view shape of the punching blade may be a shape formed by appropriately combining a straight line and a curve, or a shape composed of a plurality of curves having different curvatures.
　好ましくは、副刃は、打ち抜き刃に沿いつつ不連続に設けられることが好ましい。言い換えれば、副刃は、打ち抜き刃の全周を囲むように設けられていないことが好ましい。打ち抜き刃の全周を囲むように設けられると、打ち抜きカスが不要に分離して、分離した打ち抜きカスが製品部分に載るなどの不具合の生じるおそれがある。また、副刃を不連続に設けることにより、打ち抜き時点でフィルムにかかる力を良好に分散させることができ、フィルムのダメージをより低減することができる。 Preferably, the auxiliary blade is provided discontinuously along the punching blade. In other words, the secondary blade is preferably not provided so as to surround the entire circumference of the punching blade. If it is provided so as to surround the entire periphery of the punching blade, the punching residue is unnecessarily separated, and there is a possibility that problems such as the separated punching residue being placed on the product portion may occur. Moreover, by providing the sub-blade discontinuously, the force applied to the film at the time of punching can be well dispersed, and the damage to the film can be further reduced.
　副刃の刃長の合計長は、打ち抜き刃の刃長に対して、好ましくは１０％～８０％であり、より好ましくは３０％～６０％である。副刃の刃長の合計長は、打ち抜き刃の平面視形状、打ち抜くフィルムの特性に応じて適切に設定され得る。 The total length of the auxiliary blades is preferably 10% to 80%, more preferably 30% to 60% with respect to the blade length of the punching blade. The total length of the auxiliary blades can be appropriately set according to the shape of the punching blade in plan view and the characteristics of the punched film.
　上記打ち抜き刃の平面視形状がコーナー部を有する形状である場合、上記副刃は、少なくとも打ち抜き刃のコーナー部における該打ち抜き刃の外側（コーナー部外側）に設けられることが好ましい。打ち抜き時、コーナー部および屈曲部においては、フィルムにかかる力が不均一になりやすいため、当該部分に副刃を設けることが好ましい。 When the plan view shape of the punching blade is a shape having a corner portion, the sub blade is preferably provided at least on the outer side (outer corner portion) of the punching blade at the corner portion of the punching blade. At the time of punching, the force applied to the film tends to be non-uniform at the corner and the bent portion, so it is preferable to provide a secondary blade at the portion.
　図３（ａ）～図３（ｄ）は、本発明の１つの実施形態による打ち抜き刃および副刃の拡大平面図である。打ち抜き刃１０がコーナー部を有する場合、該コーナー部外側の副刃２０は、例えば、図３（ａ）～図３（ｄ）の形状をとり得る。すなわち、コーナー部外側の副刃２０は、打ち抜き刃１０のコーナーに沿って頂点を有する形状であってもよく（図３（ａ））、打ち抜き刃１０のコーナーに沿いつつ頂点を有さない（頂点で途切れる）形状であってもよく（図３（ｂ））、該コーナーを部分的に囲むような曲線状であってもよく（図３（ｃ））、直線状であり、該コーナーを形成する一方の辺と副刃とのなす角度ａと、該コーナーを形成する他方の辺と副刃とのなす角度ｂとの差が０°±２０°（好ましくは０°±５°）となる形状（図３（ｄ））であってもよい。好ましくは、コーナー部外側の副刃２０は、図３（ｂ）に示すように、打ち抜き刃１０のコーナーに沿いつつ頂点を有さない形状である。このようにコーナー部外側の副刃が間隔をおいて設けられていれば、打ち抜き時点にフィルムにかかる力を良好に分散させることができ、フィルムのダメージをより低減することができる。 3 (a) to 3 (d) are enlarged plan views of the punching blade and the auxiliary blade according to one embodiment of the present invention. When the punching blade 10 has a corner portion, the auxiliary blade 20 outside the corner portion can take, for example, the shapes shown in FIGS. 3 (a) to 3 (d). That is, the secondary blade 20 outside the corner portion may have a shape having a vertex along the corner of the punching blade 10 (FIG. 3A), and does not have a vertex while being along the corner of the punching blade 10 ( The shape may be cut off at the apex (FIG. 3B), may be a curved shape that partially surrounds the corner (FIG. 3C), is straight, and the corner is The difference between the angle a formed between one side to be formed and the secondary blade and the angle b formed between the other side forming the corner and the secondary blade is 0 ° ± 20 ° (preferably 0 ° ± 5 °). It may be a shape (FIG. 3D). Preferably, the secondary blade 20 outside the corner portion has a shape that does not have a vertex while being along the corner of the punching blade 10 as shown in FIG. Thus, if the sub-blade outside the corner portion is provided at an interval, the force applied to the film at the time of punching can be dispersed well, and damage to the film can be further reduced.
　図４は、本発明の１つの実施形態による打ち抜き刃および副刃の概略断面図である。なお、見やすくするため、図４における刃の高さ、ギャップ等の比率は、実際とは異なる場合がある。 FIG. 4 is a schematic cross-sectional view of a punching blade and a secondary blade according to one embodiment of the present invention. In addition, in order to make it easy to see, ratios, such as the height of a blade and a gap in FIG. 4, may differ from actual.
　打ち抜き刃１０の刃高Ａは、副刃２０の刃高Ｂよりも高いことが好ましい。このようにすれば、接触時点において、該フィルムに十分な力をかけることができる。 The blade height A of the punching blade 10 is preferably higher than the blade height B of the auxiliary blade 20. If it does in this way, sufficient force can be applied to this film at the time of contact.
　打ち抜き刃と副刃との刃高の差は、好ましくは５μｍ～７００μｍであり、より好ましくは５μｍ～５００μｍであり、さらに好ましくは５μｍ～２００μｍであり、特に好ましくは５μｍ～５０μｍであり、最も好ましくは５μｍ～１５μｍである。このような範囲であれば、打ち抜き時点において、フィルムにかかる力を良好に分散させることができる。また、打ち抜きカスの不要な分離を防止することができる。 The difference in blade height between the punching blade and the auxiliary blade is preferably 5 μm to 700 μm, more preferably 5 μm to 500 μm, still more preferably 5 μm to 200 μm, particularly preferably 5 μm to 50 μm, and most preferably. Is from 5 μm to 15 μm. If it is such a range, the force concerning a film can be favorably disperse | distributed at the time of punching. Further, unnecessary separation of the punched residue can be prevented.
　打ち抜き刃と副刃とのギャップＸ（頂点間距離Ｘ）は、打ち抜くフィルムの特性（材質、柔軟性）、形状等に応じて、任意の適切な距離に設定され得る。該ギャップＸは、好ましくは０．５ｍｍ～４ｍｍであり、より好ましくは０．５ｍｍ～２．５ｍｍである。該ギャップは、本発明の効果が得られる限りにおいて、小さい方が好ましい。ギャップを小さくすることにより、打ち抜きカスを低減でき、製品歩留まりが向上するからである。 The gap X (intervertex distance X) between the punching blade and the sub-blade can be set to any appropriate distance depending on the characteristics (material, flexibility), shape, etc. of the film to be punched. The gap X is preferably 0.5 mm to 4 mm, more preferably 0.5 mm to 2.5 mm. The gap is preferably small as long as the effects of the present invention can be obtained. This is because by reducing the gap, punching waste can be reduced and the product yield is improved.
Ｂ．フィルムの打ち抜き方法
　図５は、１つの実施形態による本発明のフィルムの打ち抜き方法を説明する概略図である。この実施形態においては、ベースプレート２００に上記刃型１００を取り付けて構成される打ち抜き手段３００が用いられる。この実施形態においては、該打ち抜き手段３００下に配置されたカッティングプレート４００上に、フィルム５００を搬送した後、該打ち抜き手段３００をフィルム５００に向け下方に移動させるか、あるいは、カッティングプレート４００を打ち抜き手段３００に向け上方移動させて、刃型１００をフィルム５００に当接させ（実質的には打ち抜き刃を当接させ）押し込むことにより、フィルム５００を打ち抜き、所定形状のフィルム片を得る。 B. Film Punching Method FIG. 5 is a schematic diagram illustrating a film punching method of the present invention according to one embodiment. In this embodiment, punching means 300 configured by attaching the blade mold 100 to the base plate 200 is used. In this embodiment, after the film 500 is transported onto the cutting plate 400 disposed under the punching means 300, the punching means 300 is moved downward toward the film 500, or the cutting plate 400 is punched. By moving upward toward the means 300 and pressing the blade mold 100 against the film 500 (substantially contacting the punching blade), the film 500 is punched to obtain a film piece of a predetermined shape.
　上記副刃は、フィルムを貫通してもよく、貫通しなくてもよい。好ましくは、副刃は、フィルムを貫通しないように（すなわち、フィルムをハーフカットするように）設けられる。 The secondary blade may or may not penetrate the film. Preferably, the auxiliary blade is provided so as not to penetrate the film (that is, so as to half-cut the film).
　本発明の打ち抜き方法に供されるフィルムとしては、任意の適切なフィルムが用いられる。１つの実施形態においては、上記フィルムとして光学フィルム用いられる。光学フィルムとしては、例えば、偏光板、位相差フィルム等が挙げられる。従来、光学フィルムは、打ち抜きによるダメージ（例えば、押し跡、剥離等）が、その特性（光学特性）に影響しやすいところ、本発明によれば、このような光学フィルムであっても、ダメージを抑制して打ち抜くことができ、外観および特性が良好なフィルムを得ることができる。 Any suitable film is used as the film to be subjected to the punching method of the present invention. In one embodiment, an optical film is used as the film. Examples of the optical film include a polarizing plate and a retardation film.

According to the present invention, even such optical films are damaged. A film having good appearance and characteristics can be obtained.
　１つの実施形態においては、打ち抜き方法に供されるフィルムとして積層フィルムが用いられる。従来の方法では、積層フィルムを打ち抜いた場合に、該積層フィルムに層間剥離（特に、フィルム片端部での剥離）が生じやすいという問題があるが、本発明によれば、層間剥離を抑制して積層フィルムを打ち抜くことができる。 In one embodiment, a laminated film is used as a film subjected to a punching method. In the conventional method, when the laminated film is punched, there is a problem that delamination (especially, delamination at one end of the film) easily occurs in the laminated film, but according to the present invention, delamination is suppressed. A laminated film can be punched out.
　打ち抜き方法に供されるフィルムの厚みは、例えば、０．１５ｍｍ～０．４５ｍｍである。 The thickness of the film subjected to the punching method is, for example, 0.15 mm to 0.45 mm.
　打ち抜き方法に供されるフィルムは、長尺状であってもよく、枚葉であってもよい。好ましくは、長尺状である。図５に示す実施形態において長尺状のフィルムを用いる場合、被加工部分をカッティングプレート上に搬送した後に、一旦搬送を止めて上記のように打ち抜き加工を行い、一度の打ち抜き加工完了後、次に打ち抜かれる被加工部分をカッティングプレートに搬送し、次の打ち抜き加工を行うという一連の動作を繰り返して、長尺状フィルムのすべてが打ち抜き加工に供される。 The film used for the punching method may be long or single-wafer. Preferably, it is long. In the case of using a long film in the embodiment shown in FIG. 5, after transporting the part to be processed onto the cutting plate, the transport is stopped and punching is performed as described above.
