Abstract
A float glass system includes a float bath having an entrance end and an exit end. At least one machine vision camera is located to view an interior of the float bath. At least one sensor is connected to the float bath to measure an operating parameter of the float bath. At least one operating device is connected to the float bath. The at least one machine vision camera, the at least one sensor, and the at least one operating device are connected to a control system configured to control the operating device based on input from the at least one machine vision camera and/or the at least one sensor.
Claims26
A float glass system, comprising:
- a float bath having an entrance end, an exit end, and a pool of molten metal;
- at least a first machine vision camera located to view an interior of the float bath;
- at least one air temperature sensor located in a headspace of the float bath and above the molten metal;
- at least one bath temperature sensor to detect the temperature of the molten metal;
- a plurality of heating coils positioned in the headspace of the float bath;
- a plurality of bath coolers located in the float bath;
- at least one roller assembly extending into an interior of the float bath comprising a barrel, a head extending into an interior of the float bath, and a movement device that controls speed of rotation of the head, tilt angle of the head, and depth of the head in a glass ribbon;
- at least a second machine vision camera associated with the at least one roller assembly;
- and
- a control system, wherein the at least first machine vision camera, the at least second machine vision camera, the at least one air temperature sensor, the at least one bath temperature sensor, the plurality of heating coils, the plurality of bath coolers, and the movement device are operatively connected to the control system, and wherein the control system is configured to continuously monitor, update, and control the movement device based on input from the at least first machine vision camera, the at least second machine vision camera, and the plurality of sensors to automatically adjust the at least one roller assembly speed of rotation of the head, tilt angle of the head, and depth of the head in the glass ribbon, and to automatically adjust thermal conditions inside the float bath to form the glass ribbon having a predetermined width or predetermined thickness.
A method of operating a float glass system, comprising:
- providing a float bath having an entrance end and an exit end;
- locating at least one machine vision camera to view an interior of the float bath;
- providing at least one sensor connected to the float bath to measure an operating parameter of the float bath;
- providing at least one operating device connected to the float bath;
- and
- connecting the at least one machine vision camera, the at least one sensor, and the at least one operating device to a control system configured to control the at least one operating device based on input from the at least one machine vision camera and the at least one sensor.
