Abstract

PURPOSE:To detect an abnormal bottle smoothly and surely by providing a rotary shutter to a rotator synchronized with the moving of bottles. CONSTITUTION:If bottles a, a- arrayed in an arrow direction are transferred by a conveyor 1, the bottles (a) engage to the projecting arms 2a of a rotator 2 which project within the moving path of the bottles and the bottles (a) advance. The rotator 2 rotated by the bottles (a) rotates a rotary shutter 6 coaxial to this. The shutter 6 is formed with light transmission parts 6a at equal distances on its hollow cylindrical peripheral wall in the positions opposite to the centers of the neck parts of the bottles. When the bottle (a) comes onto the straight line connecting a light projector 8 and a photodetector 7, if it is a normal bottle, the ray from the projector 8 is shut off by the neck part of the bottle (a) and does not reach to the photodetector 7, but if it is an abnormal bottle having a broken neck part of the bottle (a), the ray of the projector 8 transmits through the part 6a of the rotary shutter 6 and reaches to the photodetector 7. Then, the photodetector 7 emits an abnormality detecting signal.
