  • Patent number: 7245757
    Abstract: A method and a device for detecting containers, e.g. bottles of glass or plastics, or cans made of metal, wood, glass or plastics, which for recycling of materials thereof or reuse thereof are moved in a lying posture and with their axis parallel to direction of transport into or past a detection zone associated with a detector station containing a video camera, a video image analysis of the container being carried out by a video image analyser, and said detector station having an entrance and an exit. There is analysed a sequence of video images of the container whilst it is moved into or past the detection zone of the video camera, and it is determined position and movement of the container in a viewing region of the video camera on the basis of continuous detection of position and movement of the container in the video image.

  • Patent number: 7110590
    Abstract: The method of handling an empty beverage container having a bottom end and a mouth region and includes moving the container, from a return vending machine inlet, in a direction towards an outlet thereof. Through use of the method there is detected by means of a video camera the container when moved in a lying posture into or past a detection zone of the video camera and the manner by which the container is inserted at said inlet. Further, there is determined whether the container is moved into the detection zone bottom end first or mouth region end first. If the container is delivered into the detection zone with its bottom end first, the container is transported to said outlet. If, however, the container is delivered into the detection zone with its mouth region end first, then the container is caused to be returned to the inlet.

  • Patent number: 7005629
    Abstract: An optical system having a light source means and a detector means for detecting one or more articles which by means of a conveyor move or are temporarily stationary under the means, where said article(s) has/have at least one reflective portion, and where light is emitted towards the article(s) from the light source means and reflected back towards the detector means. The optical system is characterised in that at a distance above the conveyor there is provided a lens, that the light source means and the detector means are located in or essentially in the same plane which is parallel to the plane of the lens and coincident with the focal plane of the lens, and that the optical axis of the lens is coincident with an axis perpendicular to the focal plane and located halfway between the light source means and the detector means.

  • Publication number: 20040184651
    Abstract: A method of handling an empty beverage container having opposed first and second ends of different properties, the container having an axis extending between the first and second ends, said first end defined as a bottom end of the container and said second end defined as a mouth region of the container, the method comprising the step of moving the container, from a return vending machine inlet, in a direction towards an outlet thereof. Through use of the method there is detected by means of a video camera the container when moved in a lying posture into or past a detection zone of the video camera and the manner by which the container is inserted at said inlet. Further, there is determined whether the container is moved into the detection zone with its first end first or with its second end first. If the container is delivered into the detection zone with its first end first, the container is transported to said outlet.

  • Patent number: 6137900
    Abstract: In a reverse vending apparatus for detecting containers, e.g., bottles of glass or plastic, or packaging made of metal, wood, glass or plastic which for the recycling of materials or reuse of the container are inserted in the machine and conveyed past a detector station containing a video camera, a video image analyser (125, 130) is connected to the video camera in order to analyse the video image whilst the container (B) is conveyed in lying position and with its axis parallel to the direction of transport past the video camera (109). The video analyser (125) contains a calculator component (130) for determining, when the container moves into the video image, whether the container enters the detection zone (video image) mouth (B1) (e.g., top portion or neck of bottle) (FIG. 3b) first or bottom (B2) (FIG.
