Bottle inspecting device

Abstract

Abstract PURPOSE:To irradiate light to the tapered part of the bottom of a bottled to be inspected to erase its shadow and improve detection capacity for foreign matter by providing an auxiliary irradiating device which irradiates auxiliary light to the part where the shadow is produced by the refraction of the light irradiated to the bottle. CONSTITUTION:The bottle inspecting device is constituted of a bottle 1 to be inspected in an inspection position, a light source 2 for irradiating the bottom of the bottle uniformly, a detecting part 3, an auxiliary light source 4 for a light projector 5, etc. The projector 5 is disposed in a way as to encircle the bottle 1 circumferentially in correspondence to its bottom part and has a doughnut-like shape. According to such constitution, the light from the projector 5 reflects on the tapered part of the bottle bottom, and since the reflected light thereof arrives at the inspecting part 3, the shadow in the tapered part of the bottle bottom is erased when the bottle bottom is viewed from above the bottle, hence the detection capacity for foreign matter is improved.
