な加圧状層を監視することはできなかった。(Problem to be solved by the present invention) However, although this conventional technology detects the magnitude of the sealing pressure (1), it does not detect the distribution state of the sealing pressure in the longitudinal direction of the sealer part. Therefore, it was not possible to monitor the specific pressurized layer of the sealer part, such as monitoring when a part of the packaged article got caught in the sealer part.

ものである。The present invention makes it possible to detect the sealing pressure distribution state in the longitudinal direction of the sealer part with a simple configuration, and by this, it is possible to monitor the case where a part of the packaged article is caught in the sealer part, and The sealing pressure is monitored for uneven sealing pressure due to uneven thermal expansion of various parts due to heat expansion, changes in the spring force of the pressure spring due to long-term use, etc., and based on the monitoring results, immediately equal pressure is applied in the longitudinal direction of the sealer part. It is an object of the present invention to provide a method and device for monitoring the pressurized state of a sealer part, which allows readjustment and self-control of sealing pressure.

も可能であ−る。next! 211J3 and No. 381, an embodiment of the present invention will be described in detail. The sealer portion (9) is composed of an upper sealer (9A) and a lower sealer (9B), each of which has an upper sealer shaft (11). and fixed to the lower sealer shaft (12) 11. The upper sealer shaft (11) is pivotably supported by a lever pin (13) at its tip and a lever (1) which is elastically supported at the other end by a compression spring (14).
5) is rotatably fitted. Note that (16) is a spring retainer, and (17) is a seal pressure adjustment bolt. In addition, a bolt (18) for adjusting the sealer engagement strength is installed at the free end of the lever (15).The tip of the bolt (18) is a rust ball (19).
) is connected to the stopper shaft (21) of the metal fitting (20). A conical hole is formed at the tip of this adjustment bolt (18), and the hole is connected to the above-mentioned steel * (19).
By making contact with the stopper, the pressurizing force can be applied more accurately.
21). Detectors (22) such as strain gauges (for example, metal wire resistance gauges, semiconductor resistance gauges) are arranged on the left and right stopper shafts (21), respectively. ) are detected on the left and right sides in the longitudinal direction, and the detection results are displayed on the display section (23) of the operation panel via signal lines. There are various ways to display these detection results. For example, each detection result may be displayed numerically or graphically as left and right seal pressures, or the target seal pressure value or detection result may be displayed individually. It is also possible to display the deviation value from the average value or the difference itself between the detection results.In addition, these detection results and the calculation results are simply displayed on the display section (23) of the operation panel for operator's convenience. In addition to being used for toilet purposes, it is also possible to feed this back to the seal pressure adjustment mechanism to control the seal pressure intransitively.

本発明は以上のように構成されているので、検出結果で
あるシーラー部の長手方向に対する左右のシール圧を比
較検討することにより次の効果を得ることができる。(Effects of the Invention) Since the present invention is configured as described above, the following effects can be obtained by comparing and examining the left and right sealing pressures in the longitudinal direction of the sealer portion, which are the detection results.
（１）左右のシール圧に差があるときは、シーラー部の
長手方向に対する加圧状態が均等でないと判斯してこれ
を！！視し得る。(1) If there is a difference between the left and right sealing pressures, it means that the pressure in the longitudinal direction of the sealer part is not equal. ! can be seen.
（２）加熱の前後の左右のシール圧の変化を比較検討す
ることにより、シーラーの熱による各部の不均等な熱膨
張に基づく左右のシール圧に与える影響を定量的に！！
視し得る。(2) By comparing and examining the changes in the left and right seal pressures before and after heating, we can quantitatively determine the effect on the left and right seal pressures due to uneven thermal expansion of each part due to the heat of the sealer! !
can be seen.
（３）左右のシール圧の変化を比較検討することにより
、長期使用による加圧バネのバネ力の不向 等な変
化に基づく左右のシール圧に与える影響を定量的に監視
し得る。(3) By comparing and examining changes in the left and right seal pressures, it is possible to quantitatively monitor the effects on the left and right seal pressures due to changes in the spring force of the pressure spring due to long-term use.
（４）左右のシール圧の差が一定値以上であるときは、
シーラー部に被包装物品の一部が噛み込んだものとして
判斯してこれを監視し得条。(4) When the difference between the left and right seal pressures is more than a certain value,
It is possible to monitor this as if a part of the packaged article is caught in the sealer part.
