Inspection device and system for inspecting foreign matters in liquid filled in transparent container

An inspection device for detecting a foreign matter in liquid filled in a transparent container comprising:

• a first irradiation light source which is disposed backward of the transparent container and irradiates a first irradiation light to the transparent container light to the transparent container;
• a second irradiation source which is disposed at a position other than the backward of the transparent container and irradiates a second irradiation light of a color other than that of the first irradiation light to the transparent container;
• a half mirror which is disposed on a transmission light optical passage of the first irradiation light from the transparent container as well as on a reflection light optical passage of the second irradiation light from the transparent container and performs optical passage separation;
• a first filter which is disposed on a straight advancing optical passage of the half mirror and selects the transmission light from the first irradiation light;
• a first image taking means which image-takes the transmission light of the first irradiation light selected by the first filter;
• a second filter which is disposed on another optical passage of the half mirror and selects the reflection light of the second irradiation light;
• a second image taking means which image-takes the reflection light of the second irradiation light selected by the second filter;
• and
• an image processing means which image processes picture images taken by the first and second image taking means and detects foreign matters in the liquid filled in the container.

An inspection device for inspecting foreign matters in liquid filled in a transparent container which comprising;

• a first irradiation light source which is disposed backward the transparent container and irradiates a first irradiation light to the transparent container;
• a second irradiation light source which is disposed adjacent the first irradiation light source and irradiates a second irradiation light to the transparent container from a direction different from that of the first irradiation light;
• an image taking means which image takes transmission light on a transmission light optical passage of the first irradiation light from the transparent container as well as image takes irregular reflection light of the second irradiation light;
• and
• a detection means which detects foreign matters in the liquid filled in the transparent container based on the picture images taken by the image taking means.

A foreign matter inspection device for inspecting a foreign matter contaminated in liquid filled in a transparent container comprising:

• a first illumination light source which irradiates a first light to the transparent container and is disposed on one side of the transparent container and at a position substantially on a focal point of the transparent container effecting as a lens and the first illumination light source is configured in a linear shape which covers substantial longitudinal length of the transparent container;
• a second illumination light source which irradiates a second light to the transparent container and is disposed adjacent to the first illumination light source and at a position substantially on a focal point of the transparent container effecting as a lens and the second illumination light source is configured in a linear shape which covers substantial longitudinal length of the transparent container;
• an inspection use sensor means which is disposed on the other side of the transparent container at a position which permits observation of both transmission light of the first light transmitted through the transparent container and reflection light of the second light which is caused by a possible reflective foreign matter contaminated in the liquid from a same direction on an optical passage connecting between the first illumination light source and the inspection use sensor with respect to the transparent container;
• and
• an image processing unit which receives a picture image form by the transmission light and a picture image formed by the reflection light from the inspection use sensor means and determines a foreign matter contained in the liquid based on the received picture images.
