A glass product stress evaluation system is provided. The glass product stress evaluation system includes a background light source to selectively transmit light of different wavelengths and illuminates a glass product. An imaging device is mounted in proximity to the glass product and develops digitally encoded representations of internal annealing stresses formed within the glass product. The imaging device converts the digitally encoded internal stress representations into digital signals. A plurality of optical devices provides a converging view of the glass product. A plurality of filters is mounted in proximity to the plurality of optical devices and selectively transmits light of different wavelengths to the optical devices, thereby transforming detected imaged stresses in the glass product into visible colors. A processing unit receives the digital images from the imaging device and converts the digital images into visible images. The digital images can be classified into annealing grades.

Glass product stress evaluation system and method

A temperature control system fitted to a system for forming glass product is provided. The temperature control system includes a first plurality of temperature sensors configured to sense a temperature of glass products exiting an annealing lehr. The first plurality of temperature sensors is further configured to generate sensed temperature signals. A second plurality of temperature sensors configured to sense a temperature of glass products exiting a cooling fan bank. The cooling fan bank is positioned downstream from the annealing lehr. The second plurality of temperature sensors is further configured to generate sensed temperature signals. A control module is configured to receive the sensed temperature signals from the first and second plurality of temperature sensors and compare the sensed temperature signals with pre-set parameters. The control module is configured to direct adjustments in a rotational speed of a plurality of cooling fans in response to the sensed temperature signals.
