摘要： The invention relates to a method of longitudinally deflecting conveyor rolls intended for bending glass panels. The method includes deflecting the conveyor rolls during a glass-panel bending process by turning link member on which the ends of the conveyor rolls are mounted with bearings. In order to turn the link members of each conveyor roll, at least one link member is subjected to a force sufficient for its turning by a position-identifying electric drive. At least the other link member is subjected to a force sufficient for its turning by a second electric drive, which is controlled on the basis of position data provided by the position-identifying electric drive. The present invention relates also to an assembly applying the method for bending glass panels.

摘要： A glass furnace, e.g. for annealing or tempering glass, has a roller conveyor whose fused rollers rest upon stub rollers overshot by a belt which alternately overshoots and undershoots the stub rollers. A drive for the belt advantageously is controlled by a computer allowing display of the heater parameters etc. and includes a pair of motors connected to the belt with overrunning clutches and driven in opposite senses to alternately drive the belt and thereby prevent play in the movement of the latter. The heater overlying the conveyor has a matrix array of individually or collectively controllable infra-red heaters.

摘要： Sheet glass is heated during conveyance within a furnace housing having a fixed roof and vertically movable side doors that define side slots through which ends of conveyor rolls project outwardly to be supported and frictionally driven by continuous drive loops slidably driven over external support surfaces that extend alongside the side slots. A vacuum holder of the apparatus is positioned within the furnace housing above the conveyor and has a downwardly facing surface with spaced openings in which a vacuum is drawn to receive a glass sheet from the conveyor and support the sheet above the conveyor. The holder surface is disclosed as being both planar and curved and as having a porous cover of ceramic fibers so as to distribute the vacuum and prevent marring of the glass as it is supported. A greater vacuum is drawn to initially support the glass and a lesser vacuum is subsequently drawn to prevent glass deformation at the spaced openings. Vertically movable auxiliary lifters positioned between the rolls or vertical movement of the vacuum holder facilitates glass pickup. Sensing of the glass position along the conveyor and operation of a locator cooperatively provide accurate positioning of the glass on the holder surface without requiring the conveyor to be stopped prior to the holder operation. A carrier mold ring moves under the supported glass and the vacuum is then terminated so the glass drops onto the ring and bends under the bias of gravity in a manner that allows thin glass to be accurately bent. Subsequently the mold ring is moved from the furnace to a quench unit between upper and lower blastheads that temper the bent glass. Increased air is then supplied to the lower blasthead relative to the upper blasthead to lift the glass sheet off the ring and allow return of the ring to the furnace.

摘要： A conveyor drive system including an improved control circuit for a glass manufacturing apparatus transports a glass sheet through a glass processing station. The conveyor drive system includes first and second conveyor drives disposed on opposed lateral sides of the station. Each of the conveyor drives includes first and second pulleys and a continuous drive loop trained thereover. The glass plate is supported on a plurality of elongated rollers that extend between the conveyor drives and have their opposed ends supported on and in frictional engagement with the continuous drive loops. A drive motor applies drive torque to the first pulleys, and a pair of counter-poised drive motors apply a counter-torque to the second pulleys. The control circuit for controlling the energization of the first drive motor and the pair of counter-poised drive motors includes a feedback circuit which provides degenerative speed feedback for stabilizing the motion of the conveyor drive system.
