Description

本発明は、スタンディングパウチ製袋機の底シール溶着工程など、包装袋のシール溶着工程に用いるシール溶着装置に関する。   The present invention relates to a seal welding apparatus used for a seal welding process of a packaging bag such as a bottom seal welding process of a standing pouch bag making machine.

一般に、スタンディングパウチ製袋機は、底シール溶着工程にて、スタンディングパウチ容器母材と2つ折りされた底テープ材とをヒーターにて加熱している上下底シール溶着バーで溶着する。上下底シール溶着バーは、図1に示すように、上側底シール密着バー(1)と、下側底シール密着バー(2)とからなる。   Generally, in a standing pouch bag making machine, in a bottom seal welding process, a standing pouch container base material and a folded bottom tape material are welded by upper and lower bottom seal welding bars heated by a heater. As shown in FIG. 1, the upper and lower bottom seal welding bars are composed of an upper bottom seal contact bar (1) and a lower bottom seal contact bar (2).

図2に示すように、上下底シール溶着バーの一方の下側底シール溶着バー(2)を、スタンディングパウチ製袋機本体に固定されている下側底シール溶着バー取り付けプレート(7)へ装着し、上下底シール溶着バーの他方の上側底シール溶着バー(1)を、上下可動ユニットである上側底シール溶着バー取り付けプレート(4)へ装着し、スタンディングパウチ製袋機本体のカム機構(8)により前記ユニットが下降し容器母材と底テープ材とを上下底シール溶着バー(1,2)にて挟みながら溶着し容器の底部及び脚部を形成する。   As shown in FIG. 2, the lower bottom seal welding bar (2) of one of the upper and lower bottom seal welding bars is attached to the lower bottom seal welding bar mounting plate (7) fixed to the standing pouch bag making machine body. Then, the other upper bottom seal welding bar (1) of the upper and lower bottom seal welding bars is attached to the upper bottom seal welding bar mounting plate (4) which is a vertical movable unit, and the cam mechanism (8 ), The unit is lowered and welded while sandwiching the container base material and the bottom tape material between the upper and lower bottom seal welding bars (1, 2) to form the bottom and legs of the container.

スタンディングパウチ容器に充填物を注入した時、充填物の重量により2つ折りされた底テープ材の底部が下方に押し出され同時に脚部が前後に開き容器を立たせる働きをする。   When the filling material is poured into the standing pouch container, the bottom part of the bottom tape material folded in half by the weight of the filling material is pushed downward, and at the same time, the legs are opened back and forth so that the container stands up.

この底シール溶着工程において、温度、圧力、時間、上下底シール溶着バーの平坦度等が重要であり、これらの条件が一部でも満たされないと、シール不良やスローリークといった重大品質クレームに繋がってしまう。温度、時間はスタンディングパウチ製袋機本体のソフト制御により管理されており、上下底シール溶着バーの平坦度も定期的に測定具により測定をし、平坦度確認を行っている。   In this bottom seal welding process, temperature, pressure, time, flatness of the top and bottom bottom seal welding bars, etc. are important, and if these conditions are not met at all, it will lead to serious quality complaints such as seal failure and slow leak. End up. The temperature and time are managed by software control of the standing pouch bag making machine body, and the flatness of the upper and lower bottom seal welding bars is also periodically measured with a measuring tool to check the flatness.

圧力の調整は、図2に示すように、圧力調整スプリング(6)で調整を行っており、完成品の溶着厚み寸法を測定しながら圧力調整スプリングアジャストボルト(5)の締め緩めにより行う。前記圧力調整スプリングアジャストボルト(5)を緩めると前記圧力調整スプリング(6)がたわみ圧力が弱くなり、締めこむと荷重され圧力が強くなる。   As shown in FIG. 2, the pressure is adjusted by a pressure adjustment spring (6), and is adjusted by tightening and loosening the pressure adjustment spring adjustment bolt (5) while measuring the weld thickness of the finished product. When the pressure adjusting spring adjustment bolt (5) is loosened, the pressure adjusting spring (6) becomes weak in deflection pressure, and when tightened, it is loaded and pressure is increased.

従来、圧力を調整することにより、容器母材と底テープ材とを上下底シール溶着バーにて挟みながら溶着する際の上下底シール溶着バー間の隙間(以後クリアランスとも云う)を調整している。圧力が強すぎると、クリアランスが小さくなり過ぎて、包材のアルミ蒸着層を破壊し、逆に弱すぎても、クリアランスが大きくなり過ぎて、シール不足不良となり前記クレームの原因となる。   Conventionally, by adjusting the pressure, the gap between the upper and lower bottom seal welding bars when the container base material and the bottom tape material are sandwiched between the upper and lower bottom seal welding bars (hereinafter also referred to as clearance) is adjusted. . If the pressure is too strong, the clearance becomes too small, destroying the aluminum vapor deposition layer of the packaging material, and conversely, if too weak, the clearance becomes too large and the seal becomes insufficient, causing the above claims.

ところで、従来の圧力調整スプリングアジャストボルト(5)での調整では、圧力の微調整が困難で、それゆえクリアランスの調整が難しく、完成品溶着厚みのバラツキが発生し、シール不良、スローリーク等の重大クレームの原因となる。また、完成品の溶着厚みを測定しながら圧力調整スプリング(6)の調整を数回行うため時間を要していた。   By the way, in the adjustment with the conventional pressure adjustment spring adjustment bolt (5), it is difficult to finely adjust the pressure, and therefore, it is difficult to adjust the clearance, resulting in variations in the thickness of the welded product, poor seal, slow leak, etc. Causes serious claims. Moreover, it took time to adjust the pressure adjusting spring (6) several times while measuring the weld thickness of the finished product.
