  • Patent number: 9302802
    Abstract: A method of operating a plant for the treatment of containers may include treating the containers with pre-set treatment parameters by a first treatment unit of the plant. The treatment parameters are capable of being altered at least in part and depend at least in part upon product parameters—characteristic of the container—of the containers to be treated. At least one product parameter characteristic of the container is determined by detecting a recognition mark associated with the container, and at least one treatment parameter is altered on the basis of this characteristic product parameter.

  • Patent number: 8867045
    Abstract: A triggering light grid and a method for registering the position of containers and/or for checking their alignment on a conveyance path. Due to the fact that a plurality of light barriers provided at different height levels with respect to the conveyance path and having light sources that can be activated separately of one another and a shared housing are provided, as is a triggering unit for the generation of control signals on the basis of output signals of the light barriers, different container types can be registered by reprogramming the triggering light grid without mechanical adjustment of the same.

  • Patent number: 8305570
    Abstract: Method and device for determining a foam density of foam in beverage containers utilizing the Tyndall effect, and having a focused light bundle emitted into the foam by means of a light source, where the light bundle is refracted in the foam and a scattered ray becomes visible on a surface of the foam. Via a measurement of the contour of such a light spot, conclusions on the foam density can be drawn. For this, one or several lasers can be integrated into existing filling level measuring means which are coupled to the already existing measuring means.

  • Patent number: 7858942
    Abstract: A method for detecting the wall thickness of a container such as a bottle made of PET, for example, in which the absorption of radiation along a first and a second test path of the measurement radiation is ascertained, whereby the test paths intersect the container at two points of intersection such that the two test paths have at least one point of intersection approximately in common. Further, a method for detecting the wall thickness of a container such as a bottle made of PET, for example, such that the wall thickness is detected in the transitional area of a side wall of the container to a bottom area of the container.

  • Patent number: 6859270
    Abstract: A process for inspecting transparent containers (B), in which every container is illuminated and at least two exposures of the same container are produced by means of a single CCD camera (K) and evaluated, whereby one exposure images the container profile and the other exposure images the container wall, the exposure time of the CCD camera (K) is changed, between the two exposures, from an exposure time for a container to an exposure time for a container profile. A control device (C2) for changing the sensitivity of exposure of the CCD camera (K) is produced.

  • Publication number: 20030035103
    Abstract: The invention relates to a method for inspecting transparent containers (B), whereby each container is illuminated and at least two images of said container are taken and analysed by a single CCD camera (K), whereby one image pictures the container profile and the other image pictures the container wall. In between taking both images the exposure time of the CCD camera (K) is altered from a container wall exposure time to a container profile exposure time. Within the device, a controller (C2) is provided for changing the light sensitivity of the CCD camera (K).
