Description

The invention relates to a device for assembling insulating glass panes, whose interior is filled with heavy gas.

Such a device is known from EP 0 674 086 B.

The known device has two plates, between which a at least at its lower edge open insulating glass pane (package of (at least) two sheets of glass and (at least) one spacer frame between them) is arranged and from below with Heavy gas is filled. The known device has to limit of the space used in filling the insulating glass pane with Heavy gas is filled, a substantially vertical and in the direction the plane of the plates adjustable seal, so aligned is that the seal during the actual filling in close to the one vertical edge of the to be filled Insulating glass pane is arranged (FIG. 3 of EP 0 674 086 B1).

In EP 0 674 086 B1 is also an embodiment of a device for filling insulating glass panes with heavy gas, in which two plates are provided, wherein the heavy gas from a channel flows from below into the space between the plates. At one end of the press plates is a swivel seal and at the other end a seal provided in the direction the plane of the plates can be adjusted.

The invention is based on the object, starting from the device for assembling insulating glass panes whose interior is filled with heavy gas, according to EP 0 674 086 B1 a simplified Propose device in which the for filling the Insulating glass pane with heavy gas and for assembling a Insulating glass panel filled with heavy gas required Time required is shortened.

This object is achieved according to the invention with a device, which has the features of claim 1.

Preferred and advantageous embodiments of the invention Device are the subject of the dependent claims.

As in the inventive device on one of the two plates preferably on the plate, which is fixedly mounted in the machine frame is, an adjustable only transversely to the plane of the plate, in essential vertically aligned seal is provided, is eliminated the effort to align the seal so that they are the edge of Insulating glass pane, which is arranged inside the press plates, is assigned.

Another advantage of the device according to the invention consists in that the provided in the one plate seal, for example approximately in the longitudinal center of the plate from top to bottom is arranged, not from the space between the plates must be moved away when a finished filled and assembled Insulating glass pane (both panes are then all around the spacer on) is removed from the device, since it It is sufficient to simply retract the gasket into the plate, or in an embodiment in which the seal on a movable Plate is provided, the plate carrying the seal just like that move back far enough that the removal of the insulating glass pane the device is not obstructed.

In the device according to the invention can insulating glass panes be filled, in which the spacer frame at the one Glass pane rests all around and in which the second glass pane only with its upper, horizontal edge on the spacer frame is applied, so that at the bottom of the insulating glass panes a gap is open. This procedure corresponds in principle to the hand of the Fig. 1 and 2 of EP 0674 086 B1 described. Through this gap between the spacer frame and the second glass pane can Heavy gas from below into the interior of the insulating glass pane enter.

However, the device according to the invention can also be used in such a way a glass sheet is placed in the space between the plates and a second with a spacer frame occupied glass the first glass pane in the device opposite is aligned without the first glass pane the spacer frame touched somewhere. This is usually done so that the second glass sheet on the associated plate of the device Vacuum held and moved laterally out of the conveyor track. This corresponds, in principle, to FIGS. 3 to 6 of EP 0 674 086 B1 described procedure.

The feeding of heavy gas to the lower edge of the insulating glass pane is preferably done by means of a channel similar to that in the EP 0 674 086 B1, wherein in the channel in the invention but no device (piston) is provided to the effective Length of the channel to the length measured in the horizontal direction to limit the insulating glass pane. Rather, in the inventive Device of the channel in the region of at least one Gasket divided and each section of the channel is with a Formed line for supplying heavy gas.

As already indicated, in the device according to the invention even two or more, only across the plane of the one Plate be provided adjustable seals.

At both vertical edges of the plates are sealing devices, e.g. simple flaps, provided to the space between the plates to close to the outside, if an insulating glass with Heavy gas filled or an insulating glass pane, with heavy gas is filled, assembled.

In the device according to the invention with two plates, of which one fixed in the machine frame and the other in the machine frame transverse to its surface extension is adjustable exists the possibility of the adjustable seal in the fixed mounted Plate to provide. In an alternative embodiment, the adjustable seal on the adjustable plate of the device arranged.

The device according to the invention can also be set up so that in her ready-filled insulating glass panes are also pressed, so that from her finished for sealing finished insulating glass panes can be removed.

Further details, features and advantages of the invention Device will become more apparent from the following description Embodiments with reference to the drawings.

Fig. 3 is a view similar to Fig. 1 shows an embodiment with arranged in the movable plate seal.

In a machine frame 2 are two as usual to the vertical slightly inclined plates 4 and 6 are arranged, with a plate 4 is fixedly connected to the machine frame 2, whereas the other Plate 6 relative to the first plate 4 is adjustable (arrow 8) to the width of the space 10 between the plates 4, 6 change can.

At both substantially vertical edges of the plates 4 and 6 are sealing or closure devices 12, in the illustrated embodiment simple pivoting flaps, provided with which the space 10 between the plates 4, 6 closed to the outside can be.

In the stationary plate 4 is in the illustrated embodiment a exclusively transversely to the plane of the plate 4 adjustable seal 20th provided, from the bottom of the plate 4 to the top the same is formed continuously.

To adjust the seal 20 this is about push rods 24 with coupled at least one pressure medium motor 22. The connection of Seal 20 in particular of its base 26 with the push rods 24 of the pressure medium motor 22 can transversely to the plane of the plate 4 elastic be executed in order to close the device to achieve certain elastic compliance of the seal 20.

The seal 20 is with its main body 26 in a top to bottom bottom continuous groove-like, open to the space 10 recess 28 of the plate 4 sealingly guided. In the illustrated embodiment is the seal by concerns of the body 26 of the adjustable Seal 20 to sealing strip 30, which on the side walls of the Groove 28 are arranged causes. Any other kind of sealing, e.g. with the help of bellows or similar, is conceivable. At the front surface is the seal 20 with a strip 32 made of elastic compliant sealing material, e.g. an elastic foam, busy.

At the bottom of the plates 4 and 6 is a conveyor 40th provided with two longitudinal conveyor belt 42, between which outgoing from a channel 44 outlet openings 46 for Heavy gas, with which the insulating glass pane is to be filled, open. The outlet openings 46 are aligned so that they Spacer frame 60, which is placed on the one glass pane 62 is, are arranged opposite each other. The channel 44 is in the range the vertical seal 20 divided into two sections. Everyone who both sections of the channel 44 has a supply line for heavy gas, which are applied independently of each other with heavy gas can.

If an insulating glass pane is to fill, this is in one arranged upstream device, for example, so that the one glass plate 64 on the spacer frame 60, u.zw. on whose upper horizontal leg, only with its upper horizontal edge abuts, but below from the spacer frame 60th Has distance, so that the insulating glass pane (better that Glass pane package) is open at the bottom, so that heavy gas in the interior 66 of the insulating glass pane can occur. The bottom still open Insulating glass is on the conveyor belts 42 rising in moves the space 10 between the plates 4 and 6, including at the in the Machine frame 2 fixed plate mounted 4 rollers and / or outlet openings be provided for forming an air cushion can. Now, the adjustable plate 6 of the stationary plate 4th so closely approximated that they are just near the bottom of the sloping Glass panel 64, this is only with the upper horizontal Edge on the spacer frame on, is arranged. Furthermore, will the seal 20 is advanced to the plate 6 until it on the movable plate 6 is applied. This will be the section of the channel 44, above which is to be filled insulating glass, with Heavy gas applied until the insulating glass with the whole Heavy gas is filled. Then, the movable plate 6 continues to open the stationary plate 4 to be advanced, so that the first inclined Glass panel 64 entirely, i. with their entire circumference at Spacer frame 60 is present. If the device is set up is, so the closed insulating glass in the Device are also pressed and the insulating glass pane is then filled with heavy gas and for sealing the edge joint in one downstream device (sealer) finished.
