More Information
Summary:The invention relates to a method and apparatus for monitoring safety glass production or controlling a treatment process, such as a tempering process. Information representing a load of glass panels is used in controlling a treatment process, such as heating of glass panels, or in monitoring production. The information, which includes at least one of the following: shape, size, and position, is read with one or more cameras ( 6 ). This is possible as glass is made visible by means of reflected light as high intensity light is applied to the glass surface. The line camera ( 6 ) is used for receiving low intensity background light radiation incident through the glass conveying plane, a substantial increase in its intensity, as light is reflected by glass, being deciphered as glass.
