Glass Pull Rate Camera

A high temperature surveillance camera featuring a vortex cooling system, spray ring, orifice plate and insulation jacket, is mounted to view the molten glass stream as it exits the bushing, and passes into the fiberizer. The captured images are relayed to a PC in the control room which is running CantyVision™ software. The powerful image analysis software uses a number of measurement tools to provide measurement for glass pull rate (lbs or kg per hour), glass temperature, glass strand width, and glass velocity.

Minimize trim loss – The Canty float glass system consists of a high temperature Ethernet process camera and incorporates special software to reduce glare along with a unique orifice plate that prevents debris from adhering to the lens, resulting in a clear view of the glass ribbon at all times. This system is a non-contact web width control system which positions Ethernet cameras over the two glass edges and provides continuous real time measurement of web width as glass enters the Lehr annealing chamber after exiting the furnace chamber. Width measurements are made in real-time on a continuous basis, with a resolution of .015″*. CantyVision™ Client Software utilizes image based technology to continually track the extreme edge of the glass ribbon and also the edge of the knurled region formed by the top roll machines used in the float bath furnace to shape and stabilize the glass ribbon.

The CANTY Molten Glass Level system consists of a high temperature surveillance camera, mounted to view the surface of the molten glass through an opening in the wall. On the wall directly opposite the camera, a reference point is created, often by simply removing a brick from the wall, or boring a hole though it. The position of the reflection of this reference point on the surface of the glass relative to the fixed mount camera, is directly related to the molten glass level. CantyVision™ software is configured to track the position of this reflection with accuracy to 0.001” (0.025mm). A cross-hair is displayed on the operator screen image at all times, to allow the user to visually verify what point is begin tracked by the software. Control outputs are available to the DCS via OPC, 4-20mA and Modbus TCP/IP.

About us

Company details

Canty is an outgrowth of the consulting practice of John M. Canty, P.E. in designing a very deep high pressure Diving Research Facility, capable of simulating ocean depths of over a mile, he found that no lighting components were available which would withstand the required pressure of 2500 PSI. It was, therefore, necessary to develop a light that would permit illuminating the chamber at these unusual conditions. Since this vessel (now installed in the high pressure laboratory of the University at Buffalo-Department of Physiology) was to be used for manned experiments, it was desirable to keep the electrical components outside. This is due to the potential fire hazard of electrical sparks in a confined environment.
