CONVEYING APPARATUS

Abstract

Disclosed is an apparatus for conveying glass panels contains a conveying device including a feed conveyor and a removal conveyor, and also a region with a processing station. A lifting device for glass panels is provided upstream of the processing station and a lowering device for glass panels is provided downstream of the processing station, wherein a linear-conveying device is provided between the lifting device and the lowering device. It is thus possible for glass panels to be moved, by raising action, linear movement and lowering action, around a first component located in the region in the processing station, the second component therefore passing the first component. During the passing operation, the second component always remains in the conveying plane, which is the same as the plane of the second component.

Description

[0027] Further details and features of the invention will become apparent from the following description of one preferred exemplary embodiment using the attached drawings.

[0028] FIG. 1 schematically shows a device according to the invention for the transport of panes of glass and

[0029] FIG. 2 shows an apparatus according to the invention.

[0030] An apparatus 1 for the transporting of panes 2, 3 of glass comprises a feed conveyor 4, a region 5 in which a glass pane 2 is to be processed, and a removal conveyor 6.

[0031] The processing station 20 that is located in the region 5 can be, for example, a station for the application of spacers, for positioning of spacer frames, or for squaring the edges of panes of glass.

[0032] Along the entire apparatustherefore feed conveyor 4, region 5 with the processing station 20 and removal conveyor 6there is a conveying means on which glass panes 2 are transported standing along a first conveying path 21 that is designed, for example, as conveying means with rollers 7, as conveying means with conveyor belts, or as combinations of these conveying means.

[0033] A supporting device 8, for example a support wall with air cushions or rollers on which the panes of glass 2 and 3 are transported leaning, extends upward from the conveying means.

[0034] In the region of the feed conveyor 4, there is a device 10 for lifting glass panes 3 to another conveying device 11. This device 10 for lifting can have, for example, two or more than two conveyor belts, on which members 12 that protrude over the support device 8, for example through slots in the support wall, are fastened. The members 12 seize a pane 2 of glass and lift it upward (arrow 13) by corresponding actuation so that it is lifted off the feed conveyor 4 into a second conveying path 22.

[0035] As soon as the pane 3 of glass has reached the desired height, the conveying means, for example rollers 7, of the other conveying device 11 (upper conveying device) are moved out of their readiness position, in which they do not protrude over the support device, into their active position, i.e., advanced relative to the support device 8, and the pane 3 of glass is lowered onto the other upper conveying device 11.

[0036] By starting up the upper conveying device 11, the pane 3 of glass is moved past the region 5 as far as the removal conveyor 6 and is deposited there by another lifting device 16 after the conveying means of the upper conveyor device 11 is retracted to behind the support device 8 again onto the lower conveying device in the region of the removal conveyor 6 (arrow 14) and is transported out of the apparatus 1.

[0037] During this process in which a further pane 3 of glass overtakes a first pane 2 of glass that is located in the region 5 of the processing station 20, the first pane 2 of glass can be processed.

[0038] This method is especially advantageous in the production of insulating glass when the apparatus 1 according to the invention for transporting glass panes 2, 3 is located upstream from an assembly station that can also be designed as a gas filling press. Then, specifically, a first delivered pane 2 of glass can be covered with a spacer frame in region 5 or a plastic spacer is applied, while the second glass pane 3 that is then being combined with the first glass pane 2 provided with spacers to form an insulating glass blank is transported overtaking the first pane 2 of glass, so that it is the first to reach the assembly station or gas filling press and as is conventional in assembly stations and gas filling presses is kept moved out of the conveying plane until the first glass pane (with spacers) has been delivered.

[0039] In the embodiment of a device 1 according to the invention that is shown in FIG. 2, the processing station 20 provided in the region 5 is designed as a device 20 for application of plastic spacers. In this region 5, for example, there can be drivers designed as suction heads 23 that support the movements of the pane 3 of glass when the spacers are being applied.

[0040] FIG. 2 shows that in the second upper conveying path 22, there can also be a region 5 in which a pane 3 of glass can be processed. In this case, it is provided that the processing tool (processing head), as indicated by the broken line in FIG. 2, can be moved up to such an extent that it can become active in the region 5 that is located in the second conveying path 22. Alternatively, there can be another processing tool in the region 5 that is provided in the second conveying path 22. For example, there can also be drivers designed as suction heads 23 in the upper region 5.

[0041] In the embodiment that is shown in FIG. 2, the lifting device 10 and the other lifting device 16 each comprise more than two conveyor belts with members 12 at a time, so that longer glass panes 3 can also be reliably lifted upstream from the region 5 and can be reliably lowered again downstream from the region 5.

[0042] With the device according to the invention, it also becomes possible for one pane 3 of glass above the removal conveyor 6, standing on the lifting members 12 of the lowering device 16 that is located downstream from the region 5 with the processing station in the second conveying path 22, to wait until a glass pane 2 that has been processed in the region 5 has been removed past it to a downstream apparatus. This can be the case in particular when the downstream apparatus is an assembly station for producing insulating glass blanks or a gas filling press, in which insulating glass blanks filled with a gas other than air are produced, and glass panes 2 and 3 that belong together are needed.

[0043] With the apparatus according to the invention, even large (taller) panes, therefore panes that extend into the upper conveying path, can be processed when the upper conveyor has been moved back out of the active position.

[0044] Moreover, it is possible to retrofit existing systems.

[0045] In summary, one exemplary embodiment of the invention can be described as follows:

[0046] In an apparatus 1 for conveying panes 2, 3 of glass, there is a conveying device comprising a feed conveyor 4 and a removal conveyor 6, as well as a region 5 with a processing station. Upstream from the processing station is a lifting device 10, and downstream from the processing station is a lowering device 16 for panes of glass, between the lifting device 10 and the lowering device 16 there being a linear conveying device 11. Thus, glass panes 3 can be moved around a first component standing in the region 5 in the processing station by lifting (arrow 13), linear movement (arrow 17) and lowering (arrow 14), so that the second component overtakes the first component. During the overtaking process, the second component remains continuously in the conveying plane that is identical to the plane of the second component.
