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 low 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 glass sheet press bending system (20) disclosed has a bending station (30a,30b,30c,30d) for providing press bending between upper and lower molds (32,42) without intrusion into or through a conveyor (26) on which glass sheets are heated prior to the bending. The upper mold (32) is positioned above the conveyor (26), while the lower mold (42) is movable horizontally at an elevation above the conveyor from a first position adjacent the upper mold to a second position below the upper mold whereupon vertical movement therebetween performs the press bending between the molds. A transfer mold (48) receives the bent glass sheet from the upper mold (32) for cooling. Two embodiments of the bending station (30a,30c) have the lower mold continuously positioned within a heated ambient to provide a relatively hot lower mold that reduces breakage, while two other embodiments of the bending station (30b,30d) have the lower mold (42) movable out of the heated ambient after the press bending to provide a cooler mold that does not mark the glass sheets. Two embodiments of the bending station (30a,30b) have a lower mold (42) with a fixed curved shape, while the other two embodiments of the bending station (30c,30d) have a lower mold with first and second mold portions (60,62) that are movable with respect to each other to provide initial and final stages of the press bending operation. Each embodiment of the bending station has particular utility when utilized with a quench station (54) located on the opposite side of the heating conveyor (26) and the upper mold (32) as the lower mold (42) in its first position.

摘要： Apparatus and a method disclosed for use in bending heated sheets of glass (G) transported generally horizontally on a conveyor (16) within a furnace heating chamber incorporate a holder (20) located above the conveyor in a spaced relationship such that a heated sheet of glass can be transported under the holder. Gas such as air is blown upwardly from below the conveyor against the heated sheet of glass such that the sheet is moved upwardly into engagement with the holder. The upwardly blown gas is provided by an array of gas jet pumps (60) positioned below the conveyor. A mold ring (44) is then movable under the holder to receive the glass sheet for bending. Holder (20) is disclosed as including curved and planar surfaces and as including curved and planar rings. A vacuum may be drawn with the holder embodiments having the surfaces so as to assist the upwardly blown gas in lifting the sheet of glass off the conveyor. Vertical movement of the holder facilitates the lifting and also enables the curved surface and curved ring embodiments of the holder to bend the lifted glass sheet between the holder and the mold ring. Gravity bending on the mold ring forms the glass on the planar surface and planar ring embodiments of the holder and can also be used with the curved surface and ring embodiments of the holder. Movement of the mold ring to a quench station after the bending tempers the glass.

摘要： A system (10) and method disclosed for use in bending glass incorporate a vacuum holder (12) having a surface (28) with spaced openings (32) in which a vacuum is drawn to support a heated sheet of glass (G) and in which pressurized gas is subsequently supplied to force the glass sheet away from the holder surface. In one embodiment, operation of a control damper (24) initially communicates a vacuum blower (20) with the holder and subsequently communicates a positive pressure air blower (22) therewith to first draw the vacuum and then supply the pressurized air to the openings in the surface which is disclosed facing downwardly. During an intermediate step, the damper is positioned so that a reduced vacuum is drawn to prevent deformation of the heated glass sheet at the spaced openings in the holder surface. In an alternative embodiment, a gas jet pump (90) is used to produce the positive and vacuum pressures used in the practice of the invention. The gas jet pump produces the desired pressure condition by developing a large quantity, secondary flow of gas in response to a primary flow of gas. The direction of the secondary flow can be selectively controlled to develop either a positive pressure or vacuum pressure.

摘要： An improved apparatus including a localized heater that moves along the direction of conveyance with conveyed glass sheets to provide localized heating of a portion of each glass sheet to be bent without heating the rest of the glass sheet prior to its subsequent treatment. This invention is especially suitable for locally heating designated portions of glass sheets as they are heated while being conveyed through a furnace on a horizontal roller conveyor where the designated portion of glass sheets are to be formed with bends having relatively short radii of curvature at a bending station. The apparatus includes a pair of elongated localized gas heaters, each of which is positioned above the portion of the glass sheet which requires significant bending. These heaters are mounted on a carriage driven by a drive mechanism. The drive mechanism causes the carriage to move along a path parallel to the path of glass sheet conveyance to allow the heaters to continuously heat the designated portions of the glass sheet between an upstream position and a downstream position of the carriage. After the carriage reaches its downstream position, the drive mechanism causes the carriage to return to its upstream position in preparation for another cycle.
摘要翻译： 一种改进的装置，其包括沿着运送方向移动的局部加热器，其中所输送的玻璃板在其后续处理之前不加热玻璃板的其余部分，以提供待弯曲的每个玻璃板的一部分的局部加热。 本发明特别适用于当玻璃板的指定部分被加热时，通过在水平辊式输送机上的炉子输送而局部加热玻璃板的指定部分，其中指定部分的玻璃板将在弯曲处具有相对较短的曲率半径的弯曲 站。 该装置包括一对细长的局部气体加热器，每个都加热器位于玻璃板的需要大量弯曲的部分之上。 这些加热器安装在由驱动机构驱动的托架上。 驱动机构使托架沿着平行于玻璃板输送路径的路径移动，以允许加热器在托架的上游位置和下游位置之间连续加热玻璃板的指定部分。 在滑架到达其下游位置之后，驱动机构使滑架返回到其上游位置，以准备另一个循环。
