Abstract:
A tempering and cooling system for tempered glass. The tempering and cooling system is arranged on a quenching and cooling section of a tempered glass production line, wherein the quenching and cooling section comprises roller tables and chillers. A glass plate is arranged on the roller tables, a temperature sensor for collecting surface temperature of the glass plate is arranged above and/or below the roller tables, and a tempering process and/or a cooling process of the glass plate is controlled according to the surface temperature of the glass plate detected by the temperature sensors. In the tempering stage of the glass plate, when the surface temperature of the glass plate drops to the temperature of a tempering point, the glass plate enters a cooling stage. In the cooling stage of the glass plate, when the surface temperature of the glass plate drops to the temperature of a cooling point, the cooling is stopped. The tempering and cooling system controls the tempering and cooling processes according to the surface temperature of the glass plate, thereby enabling time used for tempering or cooling of the glass plate to be more precious, not only reducing the energy consumption in the production process of the tempered glass, but also improving the quality of finished tempered glass and facilitating mass production.
Abstract:
The invention relates to a method and apparatus for bending a glass panel. A heated flat glass panel (G) is fed from a furnace (1) onto a bending conveyor (4) while the bending conveyor (4) is in a straight configuration. The bending conveyor (4) and the glass panel are arched to a desired curvature while the glass panel travels along the bending conveyor (4). The bent glass panel is passed from the bending conveyor (4) onto a tempering conveyor (5) present as its extension, which has been previously arched to a desired curve as early as or even prior to having the flat glass panel received by the straight bending conveyor (4).

The invention relates to a method and apparatus for bending a glass panel. A heated flat glass panel (G) is fed from a furnace (1) onto a bending conveyor (4) while the bending conveyor (4) is in a straight configuration. The bending conveyor (4) and the glass panel are arched to a desired curvature while the glass panel travels along the bending conveyor (4). An interpolating position-setting for the tempering conveyor s (5) upstream end with respect to the tempering conveyor s bending radius is performed in such a way that a certain point (6a) at the tempering conveyor s upstream end coincides with a certain point (6a) at the bending conveyor s (4) stationary downstream end. This position-setting is performed by moving the tempering conveyor (5) in vertical and horizontal directions and by pivoting the tempering conveyor so as to change an angle (a°, b°) between its center line of curvature (CL) and a vertical line (6).
Abstract:
A glass sheet forming system (20) includes a roll bending station (28) having a lower roll conveyor (30) and an upper roll former (32) between which a heated glass sheet is progressively formed with a curved shape by lower and upper rolls (50) and (52) supported on lower and upper elongated beams (46) and (48) that extend along the direction of conveyance.
Abstract:
Method for tempering and cooling of glass in tempering machine, which includes a separate tempering section (TS) and a separate cooling section (CS), which is little longer than glass, including at least one tempering blower and air channels and nozzle arrangements (CHP) to aim the air blow onto the glass. During tempering the method divides the air from the blower/blowers in between the tempering and cooling sections in such a way, that high enough cooling effect is achieved in the tempering section for the glass being tempered.
