摘要： PROBLEM TO BE SOLVED: To provide a method and apparatus for inspecting a glass container. SOLUTION: A light source 16 guiding scattering polarized energy through a container 14 is included. A first camera 24 is arranged so as to receive not only the scattering polarized energy sent from the light source through a part of the container but also the image of a container part, wherein opaque variation appears darkly with respect to a separate bright background. A second camera 28 receives the light energy sent from the light source substantially through the same part of the container, contains a polarizer 32 in the direction crossing the polarizer of the light source, and receives the bright image of the stress variation of the container to change the polarization of the scattering polarized energy passing through the container with respect to a separate dark background. An image processor 41 is coupled with both cameras to scan the coupled image of the container part seen through a camera detecting and discriminating the change of the container as a function of comparison at every pixel between two images.

摘要： Apparatus for inspecting a container (14) for variations that affect commercial acceptability of the container that includes a light source (16) for directing diffuse polarized light energy through a container while the container is rotated about its axis. A first camera (24) is disposed to receive diffuse polarized light energy transmitted from the light source through a portion of the container, so that the first camera receives an image of the container portion in which opaque variations appear dark against an otherwise bright background. A second camera (28) receives light energy transmitted from the light source through substantially the same portion of the container, and includes a polarizer (32) at cross-orientation to the polarizer at the light source. The second camera receives a bright image of stress variations in the container, which alter polarization of the diffuse polarized light energy passing through the container, against an otherwise dark background. An image processor (41) is coupled to both of the cameras to scan associated images of the container portion viewed by the cameras for detecting and distinguishing between and among variations in the container as a function of a pixel by pixel comparison between the two images.

摘要： Apparatus (10) for detecting containers (12) of predetermined diameter that includes a pair of optical proximity sensors (28,30) positioned adjacent to a container conveyor (14) such that light energy from the sensors is incident sequently on the containers as the containers pass on the conveyor adjacent to the sensors. The sensors (28,30) are adjustable positionable with respect to each other such that the sensors are spaced from each other in the direction of container motion (60) on the conveyor. An electronic circuit (52,54,56) is coupled to the sensors (28,30) for detecting passage of containers (12) on the conveyor (14) while ignoring dithering of the containers. In the preferred embodiment of the invention, the sensors (28,30) are mounted on a common support (20) having a scale (44,46) for measuring separation between the sensors. Printed indicia in units of container diameter, preferably in both English and metric unit, is affixed to the support (20) adjacent to the scale. One (28) of the sensors is mounted on the support adjacent to a "zero" reference point on the scale indicia, and the other (30) sensor is adjustably positionable on the support adjacent to the scale. The support (20) in the preferred embodiment of the invention takes the form of a housing enclosing the sensors and having an elongated window (34) parallel to the conveyor (14) through which containers on the conveyor are exposed to the sensors.

摘要： Apparatus for detecting checks in the sidewall of a translucent container (22) that includes a light source (24) for illuminating an elongated strip of the container sidewall parallel to the central axis of the container in such a way that illumination rays are incident at any point of the strip from multiple differing angles. A camera (50) is positioned externally of the container for receiving light reflected by checks in the illuminated strip, and electronic circuitry (52) is coupled to the camera for detecting checks in the container as a function of such reflected light. Since the light rays at any point in the elongated illuminated strip on the container sidewall are incident from multiple differing angles, planar checks and split seams in the container sidewall that are not precisely vertical in orientation will have a greater chance of reflecting light energy from the source onto the camera.
