Definitions

  • the present invention provides a method for inspecting packagings of transparent material, such as for food or pharmaceutical products, wherein light is radiated into the packaging by a light source, wherein images of the illuminated packaging are recorded by a camera and wherein the images recorded by the camera are processed, wherein the light source comprises a number of approximately point-like light elements of small dimensions arranged a short distance from each other, in addition to focussing means for focussing the beam generated by the point-like light sources.
  • EP A 0 775 927 describes an optical illumination system for xerographic printers, wherein in use is made of about 25 LEDs in a closed environment .
  • LEDs with a small exit angle whereby the light concentration is further increased. LEDs are now available with an exit angle of 4-6°, while in the future LEDs will be available with an exit angle of 1 to 2°.
  • a wavelength of about 590 nm is preferably used, as this is suitable for transmission through both green and brown glass.
  • the present invention further provides a device for illuminating a relatively small area with a relatively high intensity, comprising: - a number of approximately point-like light sources arranged at a short distance from each other, wherein the number is in the order of magnitude of 100 or more and wherein a light intensity in the order of magnitude of 10,000 lux or more is generated.
  • the LEDs have a long lifespan and are particularly suitable for emitting light beams of high intensity for a short time. The lifespan of such LEDs is not adversely affected by this pulsation, in contrast to halogen lighting and the like.
  • the detection method as described in the above stated prior art publication makes use of illumination from the underside of the bottle.
  • fig. 1 shows a schematic view of an inspection station according to the present invention
  • fig. 2 is a cross-sectional view of detail II of fig. 1
  • fig. 3 is a top view of detail III of fig. 2.
  • a beer bottle B (fig.
  • the opening in head 1 has a diameter d of 45-50 mm, while the head has a height (h) of about 75 mm.
  • the focal point of the beam is situated at a distance a of 25-30 mm relative to a housing 12 of light source 7.
  • the focal length f amounts to about 185 mm.
  • the light source 7 (fig. 2) is provided in the present invention with a flat window 21 of translucent material, preferably of hard and scratch-resistant material, whereby light source 7 is extremely robust. This is further provided with an inclining upper wall 22, whereby moisture and/or dirt in an industrial environment will not adversely affect the intensity of the light source .
  • the LEDs have a small exit angle in the order of magnitude of 6°, while in the future it will become possible to achieve an exit angle of 1 to 2°.
  • LEDs with a wavelength of 590 nm are preferably utilized.
  • the interior of the housing in which the light source is accommodated can be provided with a ⁇ r cooling, wherein feed of cooled air and discharge of air can take place along a cable bushing in the housing required for the electrical connections.
  • a light-sensitive detector can further be arranged between the LEDs or on the rear side of the light source in order to measure the light intensity of the quantity of light emitted by the LEDs in a determined environment, and to regulate the power supply to the LEDs subject thereto so as to obtain the desired quantity of light in the space .

Abstract

La présente invention concerne un procédé permettant de contrôler des emballages fabriqués à partir d'un matière transparente, tels que ceux utilisés pour les produits alimentaires ou pharmaceutiques. Le procédé consiste à envoyer de la lumière dans l'emballage au moyen d'une source lumineuse ; à enregistrer, au moyen d'une caméra, les images de l'emballage illuminé puis ; à traiter les images enregistrées par la caméra. La source lumineuse comprend plusieurs sources lumineuses qui se présentent à présentent à peu prés la forme d'un point et qui sont espacées l'une de l'autre. Le procédé comprend également un moyen de mise au point permettant de régler le faisceau produit par les éléments lumineux de type point de petites dimensions.
