LEAKAGE DETECTION DEVICE OF SOFT PACKAGING CONTAINER

PROBLEM TO BE SOLVED: To provide a leakage detection device of a soft packaging container accurately and quickly detecting leakage of a specified region having a three-dimensional molding portion or the like.SOLUTION: A leakage detection device of a soft packaging container includes: a chamber which is formed by a pair of chamber vessels and stores a region to be inspected of the soft packaging container therein; pressure adjustment means for sucking air in a space in the chamber; optical displacement sensors which are respectively provided outside the pair of chamber vessels so as to measure the displacement of the region to be inspected which is stored in the chamber; and leakage determination means for determining leakage of the region to be inspected from the displacement of the region to be inspected which is measured by the optical displacement sensors. Each of the pair of chamber vessels includes a transparent window transmitting light ray of the optical displacement sensors to a surface facing the optical displacement sensors.SELECTED DRAWING: Figure 4 【課題】 立体成形部分等を有する特定領域の漏れを正確かつ迅速に検出する軟包装容器の漏れ検出装置を提供する。【解決手段】 本発明の軟包装容器の漏れ検出装置は、一対のチャンバー容器により形成され、内部に軟包装容器の被検査領域を収容するチャンバーと、チャンバー内部の空間の空気を吸引する圧力調節手段と、一対のチャンバー容器外方にそれぞれ設けられ、チャンバー内部に収容された被検査領域の変位を計測する光学式変位センサと、前記光学式変位センサにより計測された被検査領域の変位から被検査領域の漏れを判定する漏れ判定手段とを備え、前記一対のチャンバー容器は、光学式変位センサに対向する面に光学式変位センサの光線を透過する透明窓が設けられている。【選択図】図４
