安全•安心に貢献する包装品検査装置: 光学式嚙み込み検査装置 IVIS

摘要

食品の異物混入による回収報道が後を絶たない。安全•安心に対する消費者マインドが一層高まるなか，製造業における検査工程は，品質管理の要であると同時に，危機管理の最重要項目といっても過言ではない。近年，消費者の個食化が進み，多品種少量生産が増えるなか，『嚙み込み』を代表とする包装不良への対応も急務である。元来，包装不良は人による検品に頼ってきたが，さまざまな撮像技術，画像処理技術の進歩と，下流工程である梱包エリアの自動化により，急速に検査装置の導入が進んでいる。本稿では，当社が有するX線や近赤外線を利用した検査装置を例に，包装品検査装置の近況を紹介する。%The news on recall caused by food contamination is continuously heard. As consumer are more and more concerned about food contamination, inspection is the key to quality-control and at the same time the most important item in risk management. Recently, consumer's eating habit has changed and more individual food packages have been in demand. This tendency has led to high-mix low-volume production, calling for urgent measures to defective packages caused by, for example, biting". Defects of packaged products have been detected by people conventionally ； however, with the advancement of image-processing technology and automation of packaging, inspection devices have been taking place. This paper reports the recent trend of inspection devices for packaging as well as shows the X-ray and near-infrared inspections devices our company use as examples.
