摘要： A check detector for the neck and finish portion of glass bottles is disclosed. The check detectors comprises means for rotating glass bottles successively conveyed to a fixed position and a slide block which can change position freely in the width direction and vertical direction of the bottle. A plurality of light emitters for illuminating the neck and finish potion of the glass bottle are mounted to the slide block. The light by from the plurality of the light emitters is converged to the illuminated region from difference directions, and there are a plurality of light receivers equipped with light sensors for detecting the light reflected by checks in the neck and finish portion of the bottle, the light reflected by the mold seam formed at the neck and finish portions, and the directly transmitted light passing through the neck and finish portion, via lenses mounted to the slide block. There is a light emitter control section for constantly operating a plurality of light receivers in the light emitting condition so that the reflected and direct light are input as data, wherein each of the light receiving elements are divided so as to correspond to the vertical position of the neck and finish portion. The data inputted as light reflected at the seam and the data inputted as the direct light transmitted through the neck and finish portions are deleted.

摘要： A method of inspecting a transparent container for refractive defects includes positioning a light source in spaced relationship with respect to a detector which is operatively associated with a processor for receiving electrical signals from the detectors responsive to light passing through the container being received by the detector. The method includes positioning a grid filter having a plurality of alternating dark and light bands adjacent the light source so as to provide a multiple intensity gradient to the container. The container is positioned between the light source and the detector with the grid filter serving to provide adjacent alternate light and dark bands of light impinging on the container. Refractive defects will cause a distortion of the intensity gradient which will be received by the detector. In a preferred embodiment, a plurality of light and dark bands are generally horizontally oriented and produces a generally triangular wave having a constant absolute slope. A processor is employed to receive the electrical signals emitted by the detector responsive to the light impinging thereon and make a determination as to whether refractive defects exist while ignoring desired irregularities in the container. Corresponding apparatus which employs alternating light and dark bands in the grid filter and in the preferred embodiment employs dark bands of single intensity gradient and light bands of single intensity gradient. Each band has a constant gradient of light intensity passing therethrough. The grid filters produces a triangular wave having a constant absolute slope.
