Description
前記偏平状の被検査物にX線を曝射したときにX線透過量をアレイ状のラインセンサで検出して予め設定された異物混入用のしきい値と比較し異物の混入を判別して前記偏平状の被検査物の良否を判定する制御手段13を備え、
該制御手段は、さらに、前記偏平状の被検査物にX線を曝射したときに該偏平状の被検査物の中心部分についてX線透過量が予め設定された気泡判別用のしきい値以上の部分を気泡と判別する気泡有無判別手段13aと、
該気泡有無判別手段によって気泡と判別された部分の面積を算出する面積算出手段13bと、
該面積算出手段で算出された面積の合計値が予め設定された基準面積以上のときに前記被検査物の良否を判定する良否判定手段13cとを有し、
前記被検査物の異物有無の良否判定と気泡量の良否判定とを同時に行うことを特徴とする。
2 被検査物
13 制御手段
13a 気泡有無判別手段
13b 面積算出手段

- 搬送ラインに設けられたベルトコンベア上を順次水平に搬送される袋に密封された偏平状の被検査物(2)に該搬送ラインの上方からスクリーン状にX線を曝射し、このX線の曝射に伴って前記偏平状の被検査物を透過してくるX線の透過量から前記偏平状の被検査物中の異物の混入を検査するX線異物検出装置(1)において、
前記偏平状の被検査物にX線を曝射したときにX線透過量をアレイ状のラインセンサで検出して予め設定された異物混入用のしきい値と比較し異物の混入を判別して前記偏平状の被検査物の良否を判定する制御手段(13)を備え、
該制御手段は、さらに、前記偏平状の被検査物にX線を曝射したときに該偏平状の被検査物の中心部分についてX線透過量が予め設定された気泡判別用のしきい値以上の部分を気泡と判別する気泡有無判別手段(13a)と、
該気泡有無判別手段によって気泡と判別された部分の面積を算出する面積算出手段(13b)と、
該面積算出手段で算出された面積の合計値が予め設定された基準面積以上のときに前記被検査物の良否を判定する良否判定手段(13c)とを有し、
前記被検査物の異物有無の良否判定と気泡量の良否判定とを同時に行うことを特徴とするX線異物検出装置。
