Description

本発明は、フィルム又はシートを超音波カッターで切断する装置であって、多層のフィルム・シート及び接着層を含むフィルム・シートの切断に好適な装置に関する。   The present invention relates to an apparatus for cutting a film or sheet with an ultrasonic cutter, which is suitable for cutting a film or sheet including a multilayer film sheet and an adhesive layer.

従来、多層のフィルム・シート及び接着層を含むフィルム・シートの切断は、鋏やカッターナイフ等を用いて手作業で行っていた。   Conventionally, cutting of a film or sheet including a multilayer film or sheet and an adhesive layer has been performed manually using a scissors or a cutter knife.

しかし、手作業での切断は手間を要し、省力化の妨げとなる。さらに、切断面が良好でなく、割れや剥がれが生じ易く、ごみの発生量が多いという問題もある。   However, manual cutting requires labor and hinders labor saving. Furthermore, there is a problem that the cut surface is not good, cracking or peeling is likely to occur, and the amount of dust generated is large.

本発明は、このような事情に鑑み、作業の自動化が可能で、良好な切断面が得られ、ゴミの発生量が少ない切断装置を提供することを目的とする。   In view of such circumstances, an object of the present invention is to provide a cutting apparatus that can automate work, obtain a good cut surface, and generate less dust.

上記課題を解決するための本発明は、フィルム又はシートを超音波カッターで切断する装置であって、超音波カッターを移動させる移動手段と、フィルム又はシートを挟持しながら超音波カッターと一緒に移動し、フィルム又はシートの切断箇所に張力を付与する張力付与手段とを備え、張力付与手段は、フィルム又はシートを挟持する表裏一対のガイドプレートと、これらガイドプレートに形成されて超音波カッターの刃を挿通するスリットとを備え、表側のガイドプレートはスリット他端側へ向かって立ち上がる傾斜部をスリットの側方に形成し、裏側のガイドプレートはスリット他端側へ向かって立ち下がる傾斜部をスリットの側方に形成し、両方のガイドプレートのスリット他端側には、スリットの側縁から両側に延出してフィルム又はシートを挟持する挟持部を形成したことを特徴とする。 The present invention for solving the above problems is an apparatus for cutting a film or sheet with an ultrasonic cutter, and moves with the ultrasonic cutter while sandwiching the film or sheet with a moving means for moving the ultrasonic cutter. And a tension applying means for applying tension to the cut portion of the film or sheet . The tension applying means includes a pair of front and back guide plates for sandwiching the film or sheet, and blades of the ultrasonic cutter formed on these guide plates. The guide plate on the front side forms an inclined part that rises toward the other end of the slit, and the guide plate on the back side slits the inclined part that falls toward the other end of the slit. The film is formed on the side of the slit, and the other end of the slit of both guide plates extends from the side edge of the slit to both sides. It is characterized in that to form a clamping portion for clamping the sheet.

張力付与手段は、超音波カッターの移動方向に沿って延びるスリットの略半分をガイドプレートのそれぞれに形成するとともに、これらガイドプレートのスリット一端側の端部を接合してスリットを形成してあるのが好ましい。 Tensioning means may be formed in each of the approximately half of the slit extending along the moving direction of the ultrasonic cutter guide plate, the is formed with slits by joining the ends of the slits at one end of the guide plates Is preferred.

本発明によれば、張力付与手段がフィルム又はシートに張力を付与し、その状態で超音波カッターがフィルム又はシートを切断していくので、作業の自動化が可能になるばかりでなく、割れや剥がれのない良好な切断面が得られ、ゴミの発生量が少なくなる。   According to the present invention, the tension applying means applies tension to the film or sheet, and the ultrasonic cutter cuts the film or sheet in that state, so that not only the work can be automated, but also cracking and peeling. A good cut surface with no dust is obtained, and the amount of dust generated is reduced.

以下、本発明の実施形態を添付図面に基づいて詳細に説明する。
図１は本発明の切断装置１を示している。
この切断装置１は、図示しない巻き出しロールから繰り出される多層フィルムｆを超音波カッター２で幅方向に切断するものであって、移動体３を水平方向に配置されたガイドレール４で案内しながら移動させるように構成してある。超音波カッター２と張力付与手段５はブラケット６を介して移動体３に固定してある。 Embodiments of the present invention will be described below in detail with reference to the accompanying drawings.
FIG. 1 shows a cutting device 1 of the present invention.
This cutting device 1 is for cutting a multilayer film f fed from an unillustrated unwinding roll in the width direction with an ultrasonic cutter 2, while guiding a moving body 3 with a guide rail 4 arranged in a horizontal direction. It is configured to move. The ultrasonic cutter 2 and the tension applying means 5 are fixed to the moving body 3 via a bracket 6.

張力付与手段５は、表裏一対のガイドプレート７,８で多層フィルムｆを挟持して張力を付与するものである。両方のガイドプレート７,８は、矩形プレートを切り欠いて、超音波カッター２の移動方向に沿って延びるスリット９の略半分９ａ,９ｂと、スリット９の略半分９ａ,９ｂの一端から端縁に達する直線部１０ａ,１０ｂを形成してある（図４参照）。そして、両方のガイドプレート７,８の直線部１０ａ,１０ｂを突き合せて溶接接合してスリット９を形成してある。超音波カッター２の刃２ａはスリット９の他端部に挿入してある。   The tension applying means 5 applies tension by sandwiching the multilayer film f between a pair of front and back guide plates 7 and 8. Both guide plates 7, 8 are cut out from rectangular plates, and end edges from substantially one half 9 a, 9 b of the slit 9 extending along the moving direction of the ultrasonic cutter 2 and one end of the substantially half 9 a, 9 b of the slit 9. Are formed (see FIG. 4). Then, the straight portions 10a and 10b of both the guide plates 7 and 8 are butted and welded to form a slit 9. The blade 2 a of the ultrasonic cutter 2 is inserted into the other end of the slit 9.

表側のガイドプレート７はスリット他端側へ向かって立ち上がる傾斜部１１をスリット９の側方に形成してある。一方、裏側のガイドプレート８はスリット他端側へ向かって立ち下がる傾斜部１２をスリット９の側方に形成してある。さらに、両方のガイドプレート７,８のスリット他端側には、スリット９の側縁から両側に延出して多層フィルムｆを挟持する挟持部１３,１４を形成してある。また、両方のガイドプレート７,８はスリット他端側の端縁をそれぞれ上下方向に湾曲させることで、多層フィルムｆの挟持部１３,１４への進入をガイドする進入ガイド部１５,１６を形成してある。なお、表側のガイドプレート７の挟持部１３にブラケット６の下端を溶接接合してある。   The guide plate 7 on the front side has an inclined portion 11 that rises toward the other end of the slit on the side of the slit 9. On the other hand, the guide plate 8 on the back side is formed with an inclined portion 12 that falls toward the other end of the slit on the side of the slit 9. Further, on the other end side of the slits of both guide plates 7 and 8, sandwiching portions 13 and 14 are formed that extend from the side edges of the slit 9 to both sides and sandwich the multilayer film f. Further, both guide plates 7 and 8 form entrance guide portions 15 and 16 that guide the entrance of the multilayer film f into the sandwiching portions 13 and 14 by bending the edge on the other end side of the slit in the vertical direction, respectively. It is. Note that the lower end of the bracket 6 is welded to the clamping portion 13 of the front guide plate 7.

次に、この切断装置１の動作について説明する。
まず、多層フィルムｆの端縁をガイドプレート７,８の進入ガイド部１５,１６から挟持部１３,１４の間に押し込み、その後、超音波カッター２を作動させながら移動体３をガイドレール４に沿って矢印方向に移動させる。すると、多層フィルムｆが挟持部１３,１４で挟持されて張力が付与され、その状態で超音波カッター２が多層フィルムｆを切断していく。切断後の多層フィルムｆは、超音波カッター２の進行方向に向かって切断面ｃよりも右側の部分ｆａがガイドプレート８の上面側に接するのに対し、同左側の部分ｆｂはガイドプレート７の下面側に接することになる。つまり、多層フィルムｆは張力が付与された状態で切断されていくので、割れや剥がれのない良好な切断面が得られる。また、切断された多層フィルムｆは、傾斜部１１,１２を通過した後、ガイドプレート７,８のそれぞれ下側と上側に分離されるので、切断面ｃ同士の再接合を防止することができる。 Next, operation | movement of this cutting device 1 is demonstrated.
First, the edge of the multilayer film f is pushed between the entrance guide portions 15 and 16 of the guide plates 7 and 8 between the sandwiching portions 13 and 14, and then the moving body 3 is moved to the guide rail 4 while operating the ultrasonic cutter 2. Move in the direction of the arrow. Then, the multilayer film f is sandwiched between the sandwiching portions 13 and 14 and tension is applied, and in this state, the ultrasonic cutter 2 cuts the multilayer film f. In the multilayer film f after cutting, the portion fa on the right side of the cutting surface c in the traveling direction of the ultrasonic cutter 2 is in contact with the upper surface side of the guide plate 8, whereas the left side portion fb is on the guide plate 7. It will contact the lower surface. That is, since the multilayer film f is cut in a state where tension is applied, a good cut surface without cracking or peeling can be obtained. Moreover, since the cut multilayer film f is separated into the lower side and the upper side of the guide plates 7 and 8 after passing through the inclined portions 11 and 12, rejoining of the cut surfaces c can be prevented. .

なお、この切断装置１は、多層フィルムｆ以外のフィルムの他に、各種材料よりなるシートの切断に使用できることは言うまでもない。   In addition, it cannot be overemphasized that this cutting device 1 can be used for the cutting | disconnection of the sheet | seat which consists of various materials besides the film other than the multilayer film f.

また、張力付与手段５は、板金加工された一対のプレートを接合した構造であるので、製作コストが安価で済むという利点があるが、必ずしもこれに限定されるものではない。例えば、磁化したプレートで多層フィルムｆを挟持するようにしてもよい。   Further, since the tension applying means 5 has a structure in which a pair of plates subjected to sheet metal processing are joined, there is an advantage that the manufacturing cost is low, but the present invention is not necessarily limited thereto. For example, the multilayer film f may be sandwiched between magnetized plates.

本発明の切断装置は、多層のフィルム又はシート、接着層を含むフィルム又はシート、その他各種のフィルム又はシートの切断に使用できる。   The cutting device of the present invention can be used for cutting a multilayer film or sheet, a film or sheet including an adhesive layer, and other various films or sheets.
