Check detector for glass bottle neck and finish portion

摘要

A check detector of a glass bottle neck and finish portion (1) improves the check detection accuracy by positively reducing disposal of non-defective bottles. The check detector comprises a bottle rotating means (35, 36, 37) for rotating a glass bottle (3) in the course of a glass bottle handling route, a slide block (42) for changing the position in the width and vertical direction of the handling route, a plurality of light emitters (21 - 32; 60) for emitting the neck and finish portion (1) of the glass bottle (3) with light, while the emitting light is converged to the emitted region from directions which differ from each other, a plurality of light receivers (51 - 58) equipped with light receiving sensors (2) for detecting the light reflected at checks generated at the neck and finish portion (1), the light reflected at the mold seam formed at the neck and finish portion (1), and the direct light transmitting the neck and finish portion (1) via lenses (64), a light emitter control section (46) for switching a plurality of the light emitters (21 - 32; 60) successively and repeatedly in the light emitting condition, and a light receiver control section (47) for constantly operating a plurality of the light receivers (51 - 58) in the light receiving condition so that each of the reflected lights and the direct light are input as data, wherein each of the light receiving sensors is composed with diode arrays comprising a plurality of light receiving elements divided in advance so as to correspond to the vertical position of the neck and finish portion and at the same time, the data of the light reflected at the seam and the data input of the direct light transmitting the neck and finish portion are deletable, respectively.
