    Development of the World's First Defective Flute Image Inspection System for Corrugated Cardboard


    Mitsubishi Heavy Industries Machinery Systems, Ltd. (MHI-MS) has successfully developed and commercialized a new image inspection system for defective flutes in corrugated cardboard, utilizing image processing technologies for the first time in the world. We have become able to detect defective flute shaping stably and accurately by taking advantage of image processing technologies to meet the needs of customers who want to prevent defective flute cardboard during production. The introduction of this inspection system reduces jamming of corrugated cardboards with insufficient strength due to defective flute. Furthermore, there is no more need for recalls or production do-overs, which used to be caused by the mixing of defective corrugated cardboards into later processes, which has significantly improved the corrugated cardboards productivity of corrugators. Currently, this new inspection system has received positive reviews from many customers as the world's first breakthrough in the corrugated cardboard industry and has already been introduced and is operating smoothly in 9 customer plants Japan and overseas.
