Abstract:
1. A glass bottle inspection apparatus comprising: a first inspection unit which comprises plural illuminating units configured to illuminate a bottle-mouth portion of a glass bottle from an obliquely upward position and at least one camera configured to image light reflected from the glass bottle from an obliquely upward position; a second inspection unit which comprises plural illuminating units configured to illuminate the bottle-mouth portion from a lateral position and at least one camera configured to image light reflected from the glass bottle from a lateral position, said second inspection unit being disposed below said first inspection unit; a controller configured to control operations of said respective illuminating units and said respective cameras to detect a check in the bottle-mouth portion based on images captured by said camera of said first inspection unit and said camera of said second inspection unit; wherein said controller controls said respective cameras so that an image capturing timing of said camera of said first inspection unit and an image capturing timing of said camera of said second inspection unit differ from each other; said controller controls said plural illuminating units of said first inspection unit individually to emit a pulsed light in synchronism with the image capturing timing of said camera of said first inspection unit; said controller controls said plural illuminating units of said second inspection unit individually to emit a pulsed light in synchronism with the image capturing timing of said camera of said second inspection unit; and said controller detects a check which has a crack plane extending in a lateral direction in the bottle-mouth portion, based on the image captured by said camera of said first inspection unit, and detects a check which has a crack plane extending in a vertical direction in the bottle-mouth portion, based on the image captured by said camera of said second inspection unit.
