INSPECTION DEVICE FOR CAN PINHOLES |
摘要 |
Provided is a pinhole inspection apparatus for can bodies capable of effectively preventing entrance of ambient light to a photodetector side through a gap between a movable plate and a rotating turret that may be formed due to a surface condition or the like. Also provided is a pinhole inspection apparatus for can bodies capable of detecting pinholes with an even smaller diameter by using a high brightness light source. The pinhole inspection apparatus of the present invention includes: a rotating turret having a penetrating through hole; a movable plate provided on a stationary frame opposite the rotating turret; a can body holding member supporting a can body; a photodetector detecting light leaking inside the can body; and a light source irradiating the can body with light. The pinhole inspection apparatus is characterized in that a detour path formed by a pair of shield parts spaced apart a predetermined distance and opposite from each other is provided as a shield mechanism in an entire outer peripheral region of the rotating turret. |
