Apparatus for inspecting bottles
First Claim
1. A bottle inspecting apparatus for inspecting bottles having a bottle neck with a bottle finish and a thread, comprising:
- (a) means for conveying bottles while rotating the same;
(b) a first light source for exposing only the bottle finish to light;
(c) a second light source having a radiation spectrum different from that of the first light source for exposing the bottle finish and the thread of the bottle neck to light;
(d) a filter for discriminating between the light of the first light source scattered at the bottle finish and the light of the second light source scattered at the bottle finish and the thread of the bottle neck;
(e) a first photoelectric transducer having means for photoelectric array conversion of the light of the first light source scattered at the bottle finish into a first output signal;
(f) a second photoelectric transducer having means for photoelectric array conversion of the light of the second light source scattered from the bottle finish and the thread of bottle neck into a second output signal;
(g) a first defect discriminating means for digitalizing the first output signal from the first photoelectric transducer and for detecting a defect at the bottle finish;
(h) a second defect discriminating means for digitalizing the second output signal from the second photoelectric transducer and for detecting a defect at the bottle finish and the thread of the bottle neck; and
(i) means connected to said first and second discriminating means for judging the quality of bottles for providing a qualification signal in response to the output signals from the first and second defect discriminating means.

Abstract
A bottle inspecting apparatus comprises means for conveying bottles while rotating the same; a first light source for exposing only the bottle finish with light; a second light source having a radiation spectrum different from that of the first light source for exposing the thread of the bottle neck; a filter for discriminating the light of the first light source scattered at the bottle finish and the light of the second light source scattered at the bottle finish and the thread of bottle neck from the second light source; a first photoelectric transducer for photoelectric array converting the light of the first light scattered at the bottle neck into a first output signal; a second photoelectric transducer for photoelectric array converting the scattered light of the second light source from the bottle finish and the thread of bottle neck into a second output signal; a first defect discriminating circuit for digitalizing the output signal from the first photoelectric transducer and for detecting the defect at the bottle finish; a second defect discriminating circuit for digitalizing the output signal from the second photoelectric transducer and for detecting the defect at the bottle finish and the thread of the bottle neck; and a circuit for judging the quality of bottles for providing a qualification signal in response to the output signals from the first and second defect discriminating circuits.
