Definitions
- the present invention relates to the technical field of the inspection of translucent or transparent hollow articles or articles such as for example bottles or flasks, with a view to detecting any defects presented by the object and having the characteristic of reflect the light.
- the object of the invention relates more particularly to the field of the inspection of objects driven in rotation in order to detect defects as glazes by exploiting their essential characteristic which is that of reflecting the incident light.
- the glaze type defects are microcracks present in the material and which are primers for the propagation of cracks that can lead to the destruction of the object for example during a mechanical or thermal shock.
- the glazes are generally either substantially vertical, that is to say substantially parallel to the axis of longitudinal symmetry of the object, or substantially horizontal, that is to say extending in a plane substantially perpendicular to said axis of symmetry. Given the fact that such defects are likely to affect the characteristics of objects and more serious, to present a real danger for the user, the state of the art has proposed many solutions to detect glazes.

- a lighting system is adapted to provide an incident light beam focused by a lens on the upper part of the ring of the object.
- a reception system such as a matrix camera receives the light beams reflected in particular by vertical glazes during rotation of the article. The camera is connected to a processing unit indicating whether the reflected beams exceed a predetermined light intensity threshold beyond which a defect is found.

- the camera is connected to a unit for analyzing and processing the received light beams, adapted to form, at a given rate, successive images of the bottle each formed by a determined number of pixels.
- the analysis and processing unit then performs after a resynchronization of the two successive images, a difference between the pixels of the two aforementioned images and a count with respect to threshold values so as to distinguish the reflected beams of a stationary nature. corresponding to parasitic reflections, of those of variable nature corresponding to defects of the object.
- EP 1 147 405 discloses a bottle inspection device having at least five imaging heads selected from the group consisting of imaging endoscope ends and remote image sensors with respect to a camera. image processing device. Such a device aims to multiply the heads of shooting so as to increase the number of images taken during the rotation of the bottle. Such a device is a particularly expensive solution given the large number of shooting heads. Moreover, it proves in principle difficult to install as many sensors on a machine for manufacturing glass objects.
- the present invention therefore aims at remedying the drawbacks of the state of the art by proposing an optical inspection station for detecting defects reflecting light and presented by a transparent or translucent hollow object driven in rotation, such a station making it possible to detect reliably and safely glazes while limiting the number of cameras installed.
- the optical inspection station detects defects reflecting light and presented by a hollow object transparent or translucent rotated about its axis of symmetry, the inspection station comprising:
- a lighting system capable of providing a series of light beams illuminating an inspection area of the object at different incident angles
- a camera equipped with a lens making images of the inspection area during the inspection. rotation of the object
- the optical inspection station comprises a series of optical elements of deflection in the air of the rays reflected by the inspection zone, arranged between the inspection zone and the objective, so as to form in each image, a series of views of the inspection area taken under different viewing angles.

- the optical deflection elements are made by spherical lenses, cylindrical lenses, prisms or mirrors.
- the optical deflection elements are made by Fresnel prisms or Fresnel lenses.
- the lighting system and the optical deflection elements are arranged on the same side with respect to the object.
- the optical inspection station comprises deflection optical elements arranged side by side in a horizontal direction in order to detect the vertical glazes.
- the lighting system and the optical deflection elements are arranged on either side of the object.
- the optical inspection station comprises deflection optical elements superimposed in a vertical direction in order to detect the horizontal glazes.
- the optical inspection station comprises both deflection optical elements arranged side by side in a horizontal direction in order to detect the vertical glazes and optical deflection elements arranged superimposed in one direction. vertical to detect horizontal glazes.
- the optical inspection station includes a camera associated with an objective adapted to detect horizontal glazes and vertical glazes.
- the unit for analyzing and processing images makes a comparison between the information extracted from the views of the images taken so as to distinguish the reflected beams of a stationary nature from those of a mobile nature corresponding to defects of the object.
- Another object of the invention is to propose a control installation comprising means for rotating objects equipped with at least one inspection station according to the invention.
- Figure 1 is a schematic perspective view showing a first embodiment of an optical inspection station according to the invention.
- Figure 2 is a top view of the inspection station illustrated in Fig 1.
- Figure 3 illustrates an exemplary image taken by an optical inspection station according to the invention.
- Figure 4 is a view of another embodiment of an optical inspection station for the detection of horizontal glazes.

- the inspection zone Z corresponds to a limited area of the object which in the illustrated example corresponds to a part of the ring of the object.
- the lighting system 6 comprises several light sources such as light-emitting diodes or another light source associated for example with optical fibers and / or lenses. This lighting system 6 is adapted to illuminate the inspection zone Z with different angles of incidence.
- the rotation of the object 2 on a lathe along the axis of symmetry A makes it possible to obtain an inspection of the entire periphery of the object, namely the ring in the example under consideration.
- the optical inspection station 1 comprises a camera 8 equipped with an objective 9 producing images of the inspection zone Z during the rotation of the object 2.
- the camera 8 is a matrix camera for example.
- the optical inspection station 1 comprises a series of optical elements 11 of deflection in the air of the rays reflected by the inspection zone Z.

- ad field angle of the objective 9 and the camera 8 is divided into different zones ie three zones in the example. Each zone corresponds to a view of the object taken from a different angle.
- the inspection zone Z is thus observed under three different observation directions, namely:
- each optical deflection element 11 makes it possible to take the inspection zone Z at a different viewing angle in order to make the views Vi, V 2 while the viewing angle of the camera makes it possible to achieve view V 3 of the inspection zone Z so that an image I composed of three views Vi, V 2 , V 3 of the inspection zone Z taken at three distinct viewing angles can be obtained.
- the optical deflection elements 11 are made by two prisms. It should be noted that these prisms can be replaced by Fresnel lenses or mirrors.
- the camera is arranged on the other side of the object to recover the light rays.
