Abstract:
To ensure that the support force which is dependent on the pressure of a support fluid is essentially the same also in the edge area of an article (9), especially sheets of (flat) glass, which is to be held or transported, as the support force in the middle area of the surface of the article (9), the device (1) as claimed in the invention on at least one support wall (3 or 5) provides for feed openings (21) to which drain openings (23) are directly assigned.
Abstract:
A device for machining a glass plate (5) is provided with a lifting element (10,11) which is used to lift the glass plate (5) from a transport device (3) located on a lower edge of a supporting wall (1), during the machining process. The lifting element (10,11) includes lifting fingers (10) provided with clips (15) which can be applied to the lower horizontal edge (7) of the glass plate (5), in order to positively connect the lifting element (10,11) to the glass plate (5). Both a drive for lifting and lowering the lifting element and a drive for horizontally displacing the same are associated with the lifting element (10,11), such that the glass plate (5) can be displaced during the machining process, without slipping and without any time delay.
Abstract:
A blade is used to cut through a film between the panes of laminated glass in the area of a gap produced in the laminated glass the blade is provided on a holding device and can move along the gap. The holding device includes swiveling carrier on which there is a holding part for the blade with a vertical adjustment capacity. The blade is first placed next to the gap on the top of the top pane of the laminated glass. The vertical alignment of the blade is ascertained with a rule for determining the thickness of the laminated glass. Then the holding device is adjusted by a motor such that the blade falls into the gap. When a sufficient immersion depth of the blade into the gap is ascertained via the rule, the film is cut.
Abstract:
To prevent formation of a welding bead in the area of the weld on at least one wall when hollow section strips (1) are being joined by butt welding, on at least one wall of the ends of the hollow section strips (1) to be joined to one another by welding, edges (7) are produced which are set back relative to the end faces (5) of the hollow section strips (1) and the ends of the hollow section strips (1) are moved so close to one another in the execution of the welding process that the edges (7) touch and the welding process ends as soon as the edges (7) touch one another.
Abstract:
A device for dividing laminated glass (3) has two supports for laminated glass (3) which has been scratched (13, 14) on both sides and in a gap (4) between them two beams (5) which are made as suction beams. The beams (5) can be swivelled using drives (8) around horizontal axes (6) which are parallel to the dividing line such that the laminated glass (3) is arched on the one hand up and then down. By the swivelling of the beams (5) and the associated arching of the laminated glass pane (3) the fractures in the two glass panes (9, 10) are opened along the scratch lines (13, 14) which were produced beforehand, the scratch line (13) or (14) which lies on the convex side of the arched laminated glass pane (3) being opened. To separate the plastic film (15) between the glass panes (9, 10) of the laminated glass (3) a thermal radiation source (11) is used which extends preferably over the entire width of the device and which delivers thermal radiation (12) which is preferably absorbed by the plastic film (15), but not by the glass panes (9, 10) so that the latter are not significantly heated when the plastic film melts.
Abstract:
A device for transporting and cooling hot glass panes (10) has a support wall (1) in which there are alternatingly stationary support ribs (3) and between two support ribs (3) at a time there are hollow chambers (4) with wall parts (11) which are adjustable in the direction perpendicular to the glass pane (10). In the transport of a glass pane (10) the movable wall parts (11) are aligned essentially flush with the free edges (5) of the support ribs (3). When a glass pane (10) is being transported the hollow chambers (4) are exposed to hot air such that between the glass pane (10) and the support wall (1) for the wall parts (11) pushed towards the glass pane (10) a thin gas cushion (“L”) of hot air forms. When a glass pane (10) is being quenched the movable wall parts (11) are moved back to a greater distance from the glass pane (10). For quenching of a glass pane (10) cold air is blown out of the support ribs (3) in the wall parts (11) which are moved back relative to the glass pane (10). During quenching, the cold air from a wall-like hollow means (2) opposite the support wall (1) is blown onto the second side of the glass pane 10.
Abstract:
In a sorting unit for glass blanks, next to a device (1) for righting of glass blanks delivered horizontally, there is buffer storage (20) on the side opposite conveyor (10) by which glass blanks are moved to compartmented cars (60) in which they are sorted are deposited. Buffer storage (20) is a compartmented shelf with compartments formed by several tensioned cables. In buffer storage (20) glass blanks can be deposited without hindering the remaining sorting process. To align the compartments of the compartmented shelf of buffer storage (20) relative to the conveyor plane of the device (1) for righting of glass blanks, compartmented car (21) of buffer storage (20) can be adjusted relative to its base frame (22) transversely to the conveyor plane.
Abstract:
A device for bending hollow-section strips (12) with clamping and guiding jaws (20, 21). A bending support (1) is provided, which consists of two bending support parts (2, 3) that engage between clamping and guiding jaws (20, 21). Bending support parts (2, 3) are independent of the clamping and guiding jaws (20, 21), which can be adjusted in the bending plane relative to the clamping and guiding jaws (20, 21). One bending support part (2) is mounted on a support (4) and the other bending support part (3) can be shifted, relative to the bending support part (2) that is mounted on the support (4), in a direction (arrow 5) that is perpendicular to the bending plane, whereby a movable bending support part (3) is under the action of a spring (9), which urges it away from the bending support part that is mounted on the support (4). Thus, the bending support (1) is automatically adjusted to an effective width that corresponds to the width of the hollow-section strip (12). For intermediate transport of the hollow-section strip (12), the clamping and guiding jaws (20, 21) need not be moved away from the side walls of the hollow-section strip (12).
Abstract:
A process and apparatus for filling insulating glass panes (10) with filler gas comprises two plates (1 and 2) and an endless conveyor belt (9) provided at the lower rim of the plates (1 and 2), on which the insulating glass pane (10) stands with its lower, open edge. Sealing devices (30 and 31) that can be brought into contact with the vertical edges of the insulating glass pane (10) are provided between the plates (1 and 2) in order to seal the interior of the insulating glass pane (10). The sealing device (30) is associated with a connection (50) for feeding filler gas into the interior of the insulating glass pane (10). Air and air-gas mixtures can be removed from the insulating glass pane (10) via a channel formed between the other vertical edge of the insulating glass pane (10) and a sealing device (31) applied at that location, whereby air or air-gas mixture can flow out over the entire height of the open, vertical rim of the insulating glass pane (10) from the interior of the latter.
Abstract:
A spacer frame consisting of a hollow profile strip bent three times and still open at the fourth corner, wherein one leg (2) is longer than the other leg leading to the open corner, is filled with granulated desiccant by way of a probe (20) introduced into the leg (2). The probe (20) extends with its front end (20)into the leg (2') up to the desired filling level. As soon as the desiccant in the leg (2) has reached the probe (20), the feeding flow of desiccant ceases. This is detected by a sensor (27). The sensor (27) actuates the pulling out of the probe (20). During this step, a vacuum is applied to the probe (20) a distance from the front end (201) of the probe via a conduit (40) so that no desiccant can exit from the probe (20).
