Abstract
A rotary light tester for continuously inspecting empty cans discriminates between good cans and defective ones by judging the amount of transit light entering the interior of the empty cans. The light seal circular plate and the freely-reciprocative slide pusher which rotates with the continuous rotating star wheel face each other sandwiching each can receiving seat therebetween. The nozzle opening of the tip of the slide pusher vacuously holds the bottom end of an uncoated or unprinted bright can received in the can receiving seat one by one when the can enters into the empty can supply station just after the trimming. Then, in the light detection station, the opening end of the can is inserted into a groove of the light seal circular plate having a black non-luster surface to further the reflection attenuation of outer entry light, a trap is disposed in the deepest portion thereof, and a conical introduction arrangement makes it easy to insert the opening end therein by advance pushing of the slide pusher.
