Method of forming and transporting curved glass
View Patent ↗A glass forming assembly and method for forming complex shaped glass, with the glass forming assembly having a hood assembly including a hood lift superstructure movable horizontally back and forth over a cold ring and a cooling shuttle and movable vertically relative to the cold ring and the cooling shuttle, and a hood frame supported by the hood lift superstructure by a hood tilt mechanism. The hood tilt mechanism includes an air cylinder assembly actuable to tilt the hood frame relative to the hood lift superstructure, which allows for proper orientation of the glass prior to dropping it on the cooling shuttle, thus allowing for reduced glass chipping and cracking.
1. A method of forming glass into a complex shape comprising the steps of:
heating the glass;
supporting the glass on a hot ring;
moving the hot ring into a mold;
shaping the glass;
supporting the glass on a cold ring;
moving the cold ring out of the mold;
lifting the glass from the cold ring by vacuum pressure from a hood assembly;
moving the hood assembly horizontally over a cooling shuttle;
lowering a hood lift superstructure to be adjacent to the cooling shuttle;
tilting a hood frame portion of the hood lift superstructure downward thereby reorienting the glass relative to the cooling shuttle; and
releasing the vacuum pressure from the hood assembly to thereby drop the glass onto the cooling shuttle.
2. The method of claim 1 further including the steps of activating a switch as the hood frame portion is tilted downward; and preventing the cooling shuttle from moving while the switch is actuated.
3. The method of claim 2 further including the steps of tilting the hood frame portion upward; and deactivating the switch as the hood frame portion is tilted upward.
4. The method of claim 1 wherein the step of tilting the hood frame portion includes actuating an air cylinder with a solenoid valve.
