Claim of US Patent No. 9,933,373

1. A glass sheet acquisition and positioning mechanism for an inline system for measuring optical characteristics of a glass sheet, which inline system includes a background screen including contrasting elements arranged in a pre-defined pattern, a digital camera for acquiring an image of the background screen with the glass sheet positioned between the camera and the screen at a preselected position, and which inline system is installed in a system for fabricating glass sheets including one or more processing stations and one or more conveyors for conveying the glass sheet from station to station during processing, the acquisition and positioning mechanism comprising:an exterior support frame mountable in proximity to one of the one or more conveyors between the camera and the background screen;
first and second support arms configured to be operably connected to the exterior support frame for slidable and pivotal movement with respect to the exterior support frame; and
an interior support frame configured to be supported on the first and second support arms so that the interior support frame is selectively positionable with respect to the exterior support frame from a first generally horizontal orientation in a plane of the glass sheet on the one conveyor to a second, upwardly-tilted orientation whereby an upstream end of the interior support frame is elevated from a plane of the one conveyor with the glass sheet retained thereon to thereby position the glass sheet between the camera and the screen at the preselected position, and so that the interior support frame is thereafter positionable to a third orientation for releasing the glass sheet retained in the interior support frame for continued movement on the one conveyor.
