  • Window processing system comprising a cleaning station with multiple cutting surfaces
    Patent number: 8250023
    Abstract: A window processing system is disclosed for fabricating window frames. A welding station has welding heads to weld or fuse vinyl frame parts together. The frames are taken to a cleaning station having a number of cleaning heads that are independently actuated to move into a position relative selected portions of the window frame to clean off burrs, weld beads etc from the welded window frame. The cleaning process involves both training of a controller to recognize certain frame profiles and a compensation process for adjusting the cleaning process for individual variations in the frame that occur during fabrication. Real-time cleaning involves coupling a visual sensor to a moving support that also supports a cleaning tool.
