    Abstract: The invention relates to a method of optically reading portions in relief on a side wall of a container (14), the method consisting in: using a light source to light a portion of interest with a peripheral incident light beam comprising non-parallel radial light rays; using specular reflection of the beam on the portion of interest and on the portions in relief (12) through an optical element (30) to form a plane image in the field of view of a two-dimensional photoelectric sensor (24); processing the image received by the sensor in order to detect the portions in relief; and causing the light source (34) that provides the peripheral incident light beam to move relative to the optical element in translation along the direction of the theoretical central axis (A1) in order 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. The invention also provides a visualisation device and a corresponding inspection line.

    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 for detecting, on the finish of containers, defects in a horizontal mold seal of the container includes the steps of disposing the container between a light source and a camera and ensuring the rotation of the container on itself according to one rotational revolution. The camera acquires, at each increment of rotation of the container, an image so that the number of images per rotational revolution is greater than 36. The images captured for each container are analyzed such that the profile of the finish edge is detected in each image, the profiles of the finish edge of the images are compared with a reference profile of the finish edge so as to detect deviations between these profiles, and a defect in the horizontal mold seal for a container is detected when at least one image of said container has a deviation.

    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.
