Abstract:
A mold shuttle positioning system in a glass sheet forming system includes a mold mounted on a support frame. A shuttle frame including a pair of generally parallel elongate beams for receiving and supporting the mold support frame thereon. At least one support wheel assembly including a wheel and a shuttle guide is mounted in proximity to each of the shuttle beams to position and support each one of the beams as the shuttle frame is moved to position the mold supported thereon at one of multiple desired processing locations. At least one mold guide is mounted on the support surface of one of the beams for receiving and fixing the position of the mold support frame relative to the shuttle frame to align and prevent movement of the mold support frame with respect to the shuttle frame in any direction as the mold support frame is supported thereon.
Abstract:
A system (20) and method for forming a glass sheet includes a locating assembly (28) for locating at least one heated glass sheet (G) below a downwardly facing surface (58) of a topside support device (26) for transfering the heated glass sheet (G) from a conveyer (24, 24') to a mold (33) on a mold shuttle (30). The locating assembly (28) includes a support (82) mounted outside of the system housing (22) and a horizontal arm (84) extending therefrom into the heated chamber (37) of the housing (22). The arm (84) has first and second rotatably driven locators (92, 94) thereon which cooperate with additional locators (96, 97) mounted on the downwardly facing surface (58) or a second arm (84) to accurately locate one or two heated glass sheets (G) below the topside support device (26).
Abstract:
A mold apparatus for bending a glass sheet includes a main frame structure and a first mold arrangement having a first mold and a guide frame connected to the first mold. A first guide member of the guide frame is guidable by the frame structure such that it is inhibited from moving laterally in any direction, and a second guide member of the guide frame is guidable by the frame structure such that it is movable laterally away from the first guide member due to thermal expansion. The apparatus further includes a second mold arrangement including a second mold and a frame that supports the second mold such that the second mold is movable laterally relative to the frame. A sensor is also included for sensing position of one of the molds to determine whether the one mold is in a suitable position for mating with the other mold.
Abstract:
Preliminary bending of glass plate G by its dead load is performed by disposing glass plate G softened by heating on a shaping surface of frame member (34) before pressing the glass plate G between upper mold (58) and the frame member (34). The provided bend molding method comprises a step of regulating the extent of deformation of glass plate G by the preliminary bending with the use of given means for preliminary bending extent regulation (160, 170, 180, 190, 200) and a step of pressing the preliminarily bent glass plate G between the upper mold (58) and the frame member (34).
Abstract:
Apparatus and a method for forming glass sheets includes a topside transfer platen (44) that releases a heated glass sheet onto a mold supported in an upper position by a mold support frame assembly (62) which then moves the mold vertically downward and rotationally to a lower position for movement horizontally on a track (66) from below the topside transfer platen for continuation of the forming. The apparatus includes an elevator mechanism (84) having a pair of elevators (86) and an associated pair of actuators (88) that are movable different extents in order to provide the vertical and rotational movement of the mold frame support assembly (62).
Abstract:
The invention relates to a method for bending an outer and an inner glass pane of bent composite security glass sheets according to a predetermined curvature. The bending press has a bending station, an outer glass pane discharging station, an inner glass pane discharging station, and a transport shuttle between the bending station and the discharging station. The glass panes which are to be bent are introduced into the bending station one by one using a transfer path and are bent in the bending station according to the predetermined curvature of the composite security glass sheets. The outer and the inner glass panes are subjected to optimized bending in the discharging station allocated thereto at a temperature which still lies in the lower bending temperature range. In order to carry out said bending process, the glass panes are lifted from the transport shuttle by means of a take-out device with at least one optimizing contour in its edge area. The glass panes are placed on the optimizing contour and undergo optimized bending as a result. The invention also relates to an installation for implementing said method.
Abstract:
A lift device for lifting a glass sheet in a glass processing system includes a lift jet array having peripheral lift jet outlets and inner lift jet outlets disposed inwardly of the peripheral lift jet outlets. Furthermore, each lift jet outlet is operable to allow gas to flow toward the glass sheet. The lift device also includes a control unit for controlling operation of the lift jet outlets, and the control unit is configured to commence operation of at least one of the inner lift jet outlets prior to commencing operation of at least one of the peripheral lift jet outlets.
Abstract:
A hot glass sheet processing system includes a conveyor roller support structure (34) located within a heated location (32) and has an elongated cooling unit (36) having a housing (38) defining a cooling chamber (40) that receives and has bearings (42) that rotatably support an aligned set of roller ends (30). The cooling unit includes a cooling circuit that supplies cooling fluid to the cooling chamber (40) to provide cooling of the aligned set of roller ends (30) and the bearings (42).
