Abstract
A failure detection system that includes an image processing unit configured to acquire a morphological image illustrating a morphology of the absorbent article after processing of the absorbent article, in each of the plurality of steps, a failure detection unit configured to detect the existence of a failure location of the absorbent article after processing, based on the morphological image acquired by the image processing unit, and an image display unit configured to display an image of the absorbent article after processing, when a failure location of the absorbent article is detected by the failure detection unit.
Claims17
A failure detection system used in a manufacturing line of absorbent articles, the manufacturing line having a plurality of processing steps for a conveyed continuous web, the failure detection system comprising:
- an image processing unit for acquiring morphological images illustrating morphologies of entire ones of the absorbent articles after processing of the absorbent articles in each of the said processing steps;
- a failure detection unit that detects the existence of a failure location of the absorbent articles after processing, based on the morphological images acquired by the image processing unit;
- and
- an image display unit that displays images of the absorbent articles after processing, when a failure location of an absorbent article is detected by the failure detection unit,
- wherein the failure detection unit determines if a processing step has caused a processing failure by comparing subsequent acquired morphological images of a processed absorbent article with precedingly obtained morphological images of the processed absorbent article.
A failure detection method used in a manufacturing line of absorbent articles, the manufacturing line having a plurality of processing steps for a conveyed continuous web, the failure detection method comprising:
- a step of acquiring morphological images illustrating morphologies of entire ones of the absorbent articles after processing of the absorbent articles in each of the plurality of processing steps;
- a step of detecting the existence of a failure location of the absorbent articles after processing, based on the acquired morphological images;
- and
- a step of displaying images of the absorbent articles after processing, when a failure location of an absorbent article is detected,
- wherein the failure detection unit determines if a processing step has caused a processing failure by comparing subsequent acquired morphological images of a processed absorbent article with precedingly obtained morphological images of the processed absorbent article.
