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 on the film traveling on the supporting means, and a supporting means for supporting the traveling film, and the supporting means side. The present invention relates to a cutting apparatus provided with a processing roll provided with a cutting blade protruding in the direction and a processing roll support means for pressing the processing roll toward the support 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, half-cut processing that cuts the film to the middle in the thickness direction in advance so that the user can open the contents by hand without using a bag etc. What has been applied is known.
This half-cut processing is performed by laser irradiation or processing with a roll blade (see Patent Document 1).

特開２００９-１９６０７５号公報JP 2009-196075 A 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 cut in the thickness direction within a range where the thin film is not cut, the cut amount is as small as several μm to 60 μm.
If the depth of cut is shallow, the openability will be spoiled. Conversely, if the depth of cut is deep, there is a risk of damage during manufacture of the pouch container or transportation after filling. It is necessary to process with the cut depth.
However, when a roll blade is used, it is difficult to adjust the cut amount for the film, and in the case of laser irradiation, there is a problem that a large amount of power is required for processing and a large facility is required.
In order to set the cutting amount with high accuracy, there is a cutting device (see Patent Document 2 or the like) having a cutting blade composed of a base having a rectangular or trapezoidal cross section and a cutting edge protruding from the base. 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 cut amount is stabilized to some extent when the base comes into contact with the film, but due to the slight decrease in roundness and eccentric rotation of the processing roll and the support roll, the film by the base The pressing force against changes.
In addition, since the processing roll and the support roll are in contact with each other and pressed, the pressing force on the film by the base at the both ends and the center in the axial direction differs due to the bending of the processing roll and the support roll. .
The thickness of the film to be cut is slightly reduced by being pressed by the processing roll, but if the pressing force changes, the thickness of the film also changes. 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 with a simple configuration, the pressing force against the film by the processing roll can be accurately adjusted without being affected by a decrease in roundness or eccentric rotation, and the film An object of the present invention is to provide a cutting method and a cutting device capable of keeping the cutting amount constant.

The processing roll 111 provided and the processing roll support means 110 which presses the processing roll 111 to the support roll 101 side are provided.
As shown in FIGS. 3 and 4, the processing roll 111 has a contact circumferential portion 112 that defines a moving end toward the support roll 101 by contacting the film F, and the cutting blade 113 has a contact circle. Projecting from the peripheral portion 112 to the outer peripheral side.
A plurality of processing rolls 111 are provided in the width direction of the traveling film F (three in the present embodiment), and the processing roll support means 110 is provided independently corresponding to each processing roll 111.

加工ロール支持手段１１０は、図１、２に示すように、支持ロール１０１の回転軸線と平行に設けられた幅方向固定手段である幅方向固定枠１２０に支持され、固定レバー１１７の操作によって幅方向の任意の位置に移動、固定可能に形成されている。
加工ロール支持手段１１０は、加工ロール１１１を回転可能に、かつ、支持ロール１０１方向に往復動可能に支持しており、押圧力調整機構１１４によって加工ロール１１１を支持ロール１０１方向に所定の押圧力で押圧可能に構成されている。
また、加工ロール支持手段１１０は、フィルムＦに必要とされる切込加工の切り込み深さや切り込み形状に応じて、加工ロール１１１を交換可能に構成されている。 As shown in FIGS. 1 and 2, the processing roll support means 110 is supported by a width direction fixing frame 120 which is a width direction fixing means provided in parallel with the rotation axis of the support roll 101, It can be moved and fixed at any position in the direction.
The processing roll support means 110 supports the processing roll 111 so that it can rotate and reciprocate in the direction of the support roll 101, and the pressing roll adjusting mechanism 114 holds the processing roll 111 in the direction of the support roll 101 with a predetermined pressing force. It is comprised so that press is possible.
Further, the processing roll support means 110 is configured to be able to replace the processing roll 111 according to the cutting depth and the cutting shape of the cutting processing required for the film F.

さらに詳細に説明すると、加工ロール支持手段１１０は、図５、６、７に示すように、固定ベース部材１２４と、固定ベース部材１２４に対して揺動軸１２２を中心に揺動可能に設けられた揺動ベース部材１２１と、固定ベース部材１２４を幅方向固定枠１２０に支持するための固定枠部１２５及び固定レバー１１７を有している。

また、本実施形態では支持ロール１０１がフィルムＦの支持手段であるが、フィルムＦが摺動走行する平面状の支持手段であってもよい。
また、本実施形態では３つの加工ロール支持手段１１０を有したものを図示したが、加工ロール支持手段１１０の数はいくつであってもよく、各加工ロール１１１にそれぞれ適正に押圧力を付与できる構成であれば、１つの加工ロール支持手段１１０に複数の加工ロール１１１を支持させてもよい。 In the present embodiment, the cutting blade 113 is a circumferential blade parallel to the traveling direction of the film F. However, the cutting blade 113 may be zigzag or corrugated, and is intermittent or at a predetermined angle parallel to the traveling direction. It may be formed automatically, or two or more may overlap in the width direction of the film F.
In this embodiment, the support roll 101 is a support means for the film F, but may be a flat support means on which the film F slides.
Moreover, although the thing which has the three process roll support means 110 was shown in figure in this embodiment, the number of the process roll support means 110 may be how many, and it can provide a pressing force appropriately to each process roll 111, respectively. If it is a structure, you may make the one process roll support means 110 support the some process roll 111. FIG.
