After filling, the filling port 13 is sealed by heat sealing using a seal bar 14 (see FIG. 1A), whereby the contents are hermetically sealed inside. The sealing portion 11 at the filling port 13 has partial sealing failure due to the loss of heat of welding of the sealing surface due to the adhesion of the contents or steam, or the variation in the welding temperature due to the contamination of the seal bar 14 or the adhesion of foreign matter. May occur.

なるシール検査機を使用する。As shown in FIG. 1B, in order to detect a defective seal in the seal portion 11, a light source 15 for irradiating the seal portion 11 with light from one side (below) with the seal portion 11 interposed therebetween is provided. A seal inspection machine including an industrial television camera 16 as imaging means for imaging the seal portion 11 while detecting light passing through the seal portion 11 from the other side (above) of the portion 11 is used.

る。The light-emitting source 15 has a predetermined wavelength (light of a sheet member constituting the pouch 10 and the color of the heat-discoloring material 12 before discoloration is easy to transmit, and color after discoloration is difficult to transmit). (Electromagnetic wave) is applied to the seal portion 11.
【0013】工業用テレビカメラ16は、2次元撮像装

熱変色物質12の変色が生じていない箇所は、シール部
11のシール不良個所であると判断できる。The sealing characteristics of the seal portion 11 by heat sealing using the seal bar 14 are mainly governed by the maximum temperature at the interface, and if the temperature does not reach a predetermined temperature (the discoloration temperature of the heating discoloration substance 12) at the time of sealing, the welding is not performed. Insufficiently performed, resulting in defective sealing. Therefore, it can be determined that a portion of the heat discoloration substance 12 where the discoloration of the heat discoloration does not occur is a defective seal portion of the seal portion 11.

が判明する。The binarization process is performed in accordance with the intensity of the transmitted light detected by the industrial television camera 16, and the whole of the imaged seal portion 11 is taken as a bright portion above a predetermined level and a dark portion 19 below a predetermined level. Is displayed on the display 17. When the band-shaped dark portion 19 is continuously displayed on the seal portion 11 (see FIG. 2A), it is found that the welding temperature reached a predetermined welding temperature over the entire length at the time of sealing, and the sealing was successfully performed. On the other hand, when the band-shaped dark portion 19 of the seal portion 11 is shown as being interrupted on the way (see FIG. 2B), the sealing surface does not reach a predetermined welding temperature at the interrupted portion, and
It turns out that the seal failure part 18 exists in the seal part 11.

連続して表示される。The presence or absence of a defective portion may be displayed on the display 17 and determined by a human, or may be determined by an image processing device. In addition, a substance through which light is transmitted by heating can be used as the heat-discoloring substance. In this case, if the seal is normal, the bright portion is displayed continuously.

For example, the present invention can be used to inspect not only the sealing portion of the filling port but also other sealing portions for sealing failure, and there are various forms of storage bags. Further, the sheet member of the seal portion 11 may be made of a transparent member, and the discoloration of the heat discoloration substance 12 may be visually detected. In the above embodiment, the seal portion is imaged by the television camera, but light transmission of the seal portion may be detected using a transmission type photoelectric switch. In this case, it is preferable that the light emitting portion and the light receiving portion of the bag or the photoelectric switch are moved in the extending direction of the seal portion so that the seal portion is scanned in the extended direction. There are various other detection methods.
