Description

本発明は、支持手段上を走行するフィルムに、切込刃を備えた加工ロールを押圧することでフィルムに切り込みを入れる切込方法、及び、走行するフィルムを支持する支持手段と、支持手段側に突出した切込刃を備えた加工ロールと、前記加工ロールを支持手段側に押圧する加工ロール支持手段とを備えた切込装置に関する。 The present invention relates to a cutting method for making a cut in a film by pressing a processing roll provided with a cutting blade against a film running on the running film, a supporting means for supporting the running film, and a supporting means side. The present invention relates to a cutting device provided with a processing roll having a cutting blade protruding from the surface and a processing roll supporting means for pressing the processing roll toward the supporting means.

従来、樹脂製のフィルムを用いたパウチ容器において、使用者が内容物を取り出す場合に、鋏等を使わずに手で開封できるようにフィルムに予め厚さ方向の中間部まで切り込むハーフカット加工を施したものが公知である。
このハーフカット加工は、レーザー照射あるいはロール刃による加工（特許文献１等参照）で行われている。 Conventionally, in a pouch container using a resin film, when the user takes out the contents, a half-cut process is performed in which the film is cut in advance to the middle part in the thickness direction so that it can be opened by hand without using scissors or the like. The ones that have been applied are known.
This half-cut processing is performed by laser irradiation or processing with a roll blade (see Patent Document 1 and the like).

特開２００９-１９６０７５号公報Japanese Unexamined Patent Publication No. 2009-196075 特許第４４６８９３４号公報Japanese Patent No. 4468934

ハーフカット加工は、薄いフィルムに対して切断しない範囲で厚み方向に切り込みを入れるものであるため、その切込量は数μｍ～６０μｍと極めて小さなものである。
切込量が浅いと開封性がスポイルされ、逆に切込量が深いとパウチ容器の製造時や充填後の輸送時等に破損する虞が生じるため、精度良く切込量を設定し、安定した切込量で加工する必要がある。
ところが、ロール刃を用いる場合は、フィルムに対する切込量の調整が難しく、レーザー照射の場合は、加工に必要な電力が多く、大がかりな設備が必要となるという問題があった。
切込量を精度よく設定するため、断面が矩形状又は台形状の基部と、基部上に突設された刃先部とからなる切込刃を有する切込加工装置（特許文献２等参照）が公知である。 Since the half-cut process is to make a cut in the thickness direction within a range that does not cut the thin film, the cut amount is as small as several μm to 60 μm.
If the depth of cut is shallow, the openability will be spoiled, and if the amount of cut is deep, there is a risk of damage during manufacturing of the pouch container or during transportation after filling, so the depth of cut is set accurately and stable. It is necessary to process with the cut amount.
However, when a roll blade is used, it is difficult to adjust the depth of cut in the film, and in the case of laser irradiation, there is a problem that a large amount of electric power is required for processing and a large-scale equipment is required.
In order to set the cutting amount accurately, a cutting device having a cutting edge consisting of a base having a rectangular or trapezoidal cross section and a cutting edge portion protruding from the base (see Patent Document 2 and the like). It is known.

特許文献２に記載の技術では、基部がフィルムに当接することで、切込量はある程度安定するが、加工ロール、支持ロールの僅かな真円度の低下や偏心回転の影響で、基部によるフィルムに対する押圧力が変化する。
また、加工ロールと支持ロールを両端部で接触させて押圧する構造であるため、加工ロール、支持ロールの撓みの影響によって軸方向の両端部と中央部で基部によるフィルムに対する押圧力が異なってしまう。
切り込まれる部分のフィルムの厚みは加工ロールに押圧されてわずかに薄くなるが、押圧力が変動するとフィルムの厚みも変動し、刃先部の突出量を正確に設定しても、切込量が一定にならないという問題があった。 In the technique described in Patent Document 2, the depth of cut is stabilized to some extent by the contact of the base with the film, but the film due to the base is affected by a slight decrease in roundness of the processing roll and the support roll and the influence of eccentric rotation. The pressing force against changes.
In addition, since the structure is such that the processing roll and the support roll are brought into contact with each other at both ends and pressed, the pressing force against the film by the base differs between both ends and the center in the axial direction due to the influence of the bending of the processing roll and the support roll. ..
The thickness of the film to be cut is slightly thinned by being pressed by the processing roll, but when the pressing pressure fluctuates, the thickness of the film also fluctuates, and even if the protrusion amount of the cutting edge is set accurately, the depth of cut is large. There was a problem that it was not constant.

本発明は、前記した問題点を解決するものであり、簡単な構成で、真円度の低下や偏心回転の影響を受けることなく、加工ロールによるフィルムに対する押圧力を正確に調整でき、フィルムの切込量を一定に保持可能な切込方法及び切込装置を提供することを目的とするものである。 The present invention solves the above-mentioned problems, and can accurately adjust the pressing force on the film by the processing roll without being affected by the decrease in roundness or the eccentric rotation with a simple configuration.
