Abstract: An inspection device which is compatible with in-line inspection of containers and reliably determines the presence or not of a defect of a container, has a lighting system arranged above an installation zone and being capable of providing an incident light beam, an image sensor connected to an image-analysis unit, and an optical system with a first primary reflection surface arranged above the installation zone and interposed between the installation zone and the sensor for forming on the sensor an image of a container ring surface to be inspected. Also included is a second primary reflection surface in the upstream field of vision of the sensor to reflect light beams, directly or indirectly in the direction of the sensor. The first and second primary reflection surfaces determine first and second portions of a downstream field of vision, which overlap in the inspection zone.

Abstract: A method, device, and inspection line for optically reading portions in relief on a side wall of a container, includes using a light source to light a portion of interest with a peripheral incident light beam comprising non-parallel radial light rays and using specular reflection of the beam on the portion of interest and on the portions in relief through an optical element to form a plane image in the field of view of a two-dimensional photoelectric sensor. The image received by the sensor is processed in order to detect the portions in relief to cause the light source that provides the peripheral incident light beam to move relative to the optical element in translation along the direction of a theoretical central axis to modify the contrast of the image received by the sensor between zones of the image that correspond to the portions in relief and adjacent zones.

Abstract: The invention relates to an installation for observing or illuminating a container (2) section (t) travelling in translation and each having an axis of revolution (S), the installation including optical systems (61) translationally guided along a parallel direction an adjustment portion of their respective optical paths, and which have, for containers having a section with a first diameter, their respective work volumes each coincident with a part of said container section having the first diameter, the installation including at least one driving device (15) providing, when the containers have a section with a second diameter different to the first diameter, the movement in synchronous translation of the optical systems along a direction parallel to the adjustment portion of their respective optical paths and as a function of the difference between the first and the second diameter.

Abstract: A method of determining a presence of a wire-edge at the site of an internal edge of a ring surface of a ring of a container includes lighting of the ring surface of the container from above using a radial light beam at 360 and observing the ring surface according to a peripheral observation field. A first principal circle is formed in a first image zone. At least one secondary arc of a circle concentric to the first so-called principal circle, and radially offset relative to the latter is also formed in the first image zone. The first so-called principal circle and any first secondary arc of a circle are searched using the first image zone. A device for executing the determining method is provided along with a line including the device.
