    Zum Zuführen von Schwergas in den seitlich durch die Dichteinrichtungen 30 und 31 begrenzten Raum 8 zwischen den Platten 1 und 2 ist im Bereich des Bandförderers 9 ein Kanal 122 vorgesehen, aus dem Schwergas wie durch Pfeile 156, 157 symbolisiert durch den Bandförderer 9 von unten her in den Raum 8 einströmt. Die wirksame Länge des Kanals 122 wird durch einen Kolben 130 auf die Länge der Isolierglasscheibe 10 begrenzt.For feeding heavy gas into the side through the sealing devices 30 and 31 limited space 8 between the plates 1 and 2, a channel 122 is provided in the area of the belt conveyor 9, from the heavy gas as symbolized by arrows 156, 157 by the belt conveyor 9 from below into the room 8 flows in. The effective length of channel 122 is determined by a Piston 130 limited to the length of the insulating glass pane 10.

    In den Fig. 7 bis 9 ist eine Ausführungsform für den Kanal 122 zum Zuführen von Schwergas gezeigt. Bei dieser Ausführungsform ist der Kanal 122 unterhalb des Trägers 120 für die Führungsleiste 172 des längsgeteilten Bandförderers 9 (im Beispiel zwei Endloszahnriemen 121) befestigt. Vom Innenraum 123 des Kanals 122 gehen Bohrungen 124 aus, die mit Bohrungen 125 im Träger 120 fluchten und schließlich zu Rohrstücken 126 führen, die den Spalt zwischen den beiden Zahnriemen 121 des Bandförderers 9 durchsetzen. Die Rohrstücke 126 münden im Raum 8 zwischen den Platten 1 und 2 und insbesondere zwischen den beiden Glasscheiben 11 und 13 der noch nicht fertig zusammengestellten Isolierglasscheibe 10 und sind so ausgerichtet, daß sie dem Abstandhalter 14 gegenüberliegen.7 to 9 is an embodiment for the channel 122 shown for supplying heavy gas. In this embodiment is the channel 122 below the carrier 120 for the guide rail 172 of the longitudinally divided belt conveyor 9 (in the example two endless toothed belts 121) attached. From the interior 123 of the Channel 122 go out of holes 124, which with holes 125 in Align carrier 120 and finally lead to pipe sections 126, which the gap between the two toothed belts 121 of the belt conveyor 9 enforce. The pipe sections 126 open in space 8 between plates 1 and 2 and in particular between the two Glass panes 11 and 13 of the not yet completed Insulating glass pane 10 and are aligned so that they the spacer 14 are opposite.

    An Stelle der Bohrungen 124, 125 und der Rohstücke 126, über die der Innenraum 123 des Kanals 122 mit dem Raum 8 zwischen den Platten 1 und 2 in Verbindung steht, kann auch eine Reihe von Längsschlitzen oder ein durchgehender Schlitz vorgesehen sein.Instead of the holes 124, 125 and the raw pieces 126, about which the interior 123 of the channel 122 with the space 8 between the plates 1 and 2 is connected, a series can also of longitudinal slots or a continuous slot be.

    Der Innenraum 123 des Kanals 122 steht über eine Verbindungsleitung (nicht gezeigt) mit einer Quelle für Schwergas (Edelgas, Schwefelhexafluorid od.dgl.) in Verbindung.The interior 123 of the channel 122 stands over a connecting line (not shown) with a source of heavy gas (rare gas, Sulfur hexafluoride or the like) in connection.

    Der Kolben 130, durch den die wirksame Länge des Innenraums 123 des Kanals 122 auf die in horizontaler Richtung gemessene Länge der Isolierglasscheibe 10 angepaßt werden kann, ist gegenüber dem Kanal 122 durch zwei Dichtungen 131 abgedichtet. Durch einen Längsschlitz 134 in dem den Bohrungen 124 gegenüberliegenden Bereich des Kanals 122 ragt ein Ansatz 135, der mit dem Kolben 130 verbunden ist, nach außen. Über diesen Ansatz 135 kann der Kolben 130 im Kanal 122 verstellt werden.The piston 130, through which the effective length of the interior 123 of the channel 122 to that measured in the horizontal direction Length of the insulating glass pane 10 can be adjusted sealed against the channel 122 by two seals 131. Through a longitudinal slot 134 in the opposite of the holes 124 A portion 135 protrudes from the area of the channel 122 connected to the piston 130 to the outside. About this approach 135, piston 130 can be adjusted in channel 122.

    Der Schlitz 134 im Kanal 122 ist durch eine Dichtung 136 abgedichtet, die im Bereich des Kolbens 130, d.h. im Bereich zwischen den beiden Dichtungen 131 (druckloser Raum) nach innen umgelenkt und unter dem Ansatz 135 durchgeführt ist. Auf diese Weise kann der Kolben 130 beliebig verstellt werden, ohne daß die Dichtigkeit des Kanals 122 nach außen hin durch den Schlitz 134 beeinträchtigt wird.The slot 134 in the channel 122 is sealed by a seal 136, those in the area of the piston 130, i.e. in the range between the two seals 131 (unpressurized space) to the inside deflected and carried out under the approach 135. To this In this way, the piston 130 can be adjusted as desired without the tightness of the channel 122 to the outside through the Slot 134 is affected.

    Es ist bevorzugt, daß das Verstellen des Kolbens 130 über dessen Ansatz 135 mit dem Verstellen der beweglichen Dichtung 31 kombiniert ist.It is preferred that the displacement of the piston 130 be above it Approach 135 with the adjustment of the movable seal 31 is combined.

    Die Vorrichtung arbeitet beispielsweise wie folgt:
    Eine beispielsweise in der aus der AT 370 201 B oder der AT 370 706 B bekannten Vorrichtung oder von Hand aus zusammengestelltes Paket aus Glasscheiben 11 und 13 und einem Abstandhalter 14, deren eine Glasscheibe 13 unten von dem auf die andere Glasscheibe 11 angesetzten Abstandhalter 14 einen Abstand (Spalt 60) aufweist, und an dem auf der anderen Glasscheibe 11 angesetzten Abstandhalter 14 lediglich im oberen Bereich anliegt, so daß unten und teilweise an den lotrechten Rändern der Glasscheiben 11 und 13 ein Zugang in den Innenraum des Paketes vorliegt, wird auf dem Bandförderer 9 aufstehend in den Raum 8 zwischen den Platten 1 und 2 gefördert, bis ihr, bezogen auf die Förderrichtung (Pfeil 25) vorderer, vertikaler Rand neben der vorgeschobenen oder eingeschwenkten Dichteinrichtung 30 liegt. Nun wird die zweite Dichteinrichtung 31 im Raum 8 zwischen den beiden Platten 1 und 2 verschoben bis sie neben dem, bezogen auf die Förderrichtung (Pfeil 25) hinteren, vertikalen Rand der Isolierglasscheibe 10 liegt.    The device works, for example, as follows:
    A package of glass panes 11 and 13 and a spacer 14, for example in the device known from AT 370 201 B or AT 370 706 B or assembled by hand, and one spacer 14, the one glass pane 13 of which is at the bottom of the spacer 14 placed on the other glass pane 11 Has distance (gap 60), and on the spacer 14 attached to the other glass pane 11 only rests in the upper region, so that there is access to the interior and interior of the package at the bottom and partially at the vertical edges of the glass panes 11 and 13 Belt conveyor 9, standing up, is conveyed into the space 8 between the plates 1 and 2 until, in relation to the conveying direction (arrow 25), the front, vertical edge lies next to the advanced or pivoted-in sealing device 30. Now the second sealing device 31 is displaced in space 8 between the two plates 1 and 2 until it lies next to the vertical edge of the insulating glass pane 10, which is at the rear in relation to the conveying direction (arrow 25).

    Hierauf wird die bewegliche Platte 2 so weit auf die feststehende Platte 1 vorgeschoben, daß die bewegliche Platte 2 die ihr benachbarte Glasscheibe 13 an ihrem auf dem Bandförderer 9 aufstehenden Rand berührt und die Glasscheibe 13 im Bereich ihres unteren Randes abstützt. Sobald dies geschehen ist, kann mit dem Gastausch, wie weiter unten beschrieben, begonnen werden.Then the movable plate 2 is so far on the fixed Plate 1 advanced that the movable plate 2 the its adjacent glass pane 13 on its on the belt conveyor 9 touches the upstanding edge and the glass pane 13 in the area supports its lower edge. Once this is done, you can started with the gas exchange as described below will.

    Mit der erfindungsgemäßen Vorrichtung kann (vgl. Fig. 4 bis 6) auch so gearbeitet werden, daß während des Füllvorganges die eine Glasscheibe 13 an der beweglichen Platte 2 zur Gänze im Abstand vom auf die andere Glasscheibe 11 angesetzten Abstandhalter 14 gehalten wird. Dies ist ohne weiteres möglich, wenn die Platte 2 zum Halten der Glasscheibe 13 eingerichtet ist. Beispielsweise kann die Platte 2 an ihrer dem Raum 8 zwischen den Platten 1 und 2 zugewendeten Fläche Öffnungen aufweisen, die über eine Leitung 12' mit Unterdruck beaufschlagt werden, um die Glasscheibe 13 festzuhalten.With the device according to the invention (cf. FIGS. 4 to 6) also be worked so that during the filling process a glass plate 13 on the movable plate 2 in the whole Distance from the spacer attached to the other glass pane 11 14 is held. This is easily possible if the plate 2 is set up to hold the glass pane 13. For example, the plate 2 on the space 8 between have openings facing the plates 1 and 2, which are subjected to negative pressure via a line 12 ', to hold the glass pane 13 in place.

    Als ersten Arbeitsschritt dieser Variante des Zusammenbauens einer mit Schwergas gefüllten Isolierglasscheibe 10 wird eine erste Glasscheibe 13 an der Platte 1 lehnend und unten vom Förderband 9 gestützt in den Raum 8 zwischen den Platten 1 und 2 bis in eine vorgegebene Endstellung bewegt (Fig. 4). Um den Transport der Glasscheibe 13 zu erleichtern, kann die Platte 1 als Luftkissenwand ausgebildet sein und es wird ihr beim Antransport der Glasscheibe 13 über eine Anschlußleitung 12 Druckluft zugeleitet.As the first step in this variant of assembly an insulating glass pane 10 filled with heavy gas becomes one first glass plate 13 leaning against the plate 1 and below Conveyor belt 9 supported in the space 8 between the plates 1 and 2 moved into a predetermined end position (Fig. 4). To the To facilitate transport of the glass sheet 13, the plate 1 be designed as an air cushion wall and it will be transported to you the glass pane 13 via a connecting line 12 Compressed air supplied.

    Sobald die Glasscheibe 13 ihre vorgegebene Endstellung erreicht hat, wird die verstellbare Platte 2 vorgeschoben, bis sie mit ihrer der Platte 1 zugekehrten Fläche an der Glasscheibe 13 anliegt. Sobald dies erreicht ist, wird die Platte 2, die an ihrer dem Raum 8 zwischen den Platten 1 und 2 zugekehrten Seite Öffnungen aufweist, über eine Leitung 12' mit Unterdruck beaufschlagt und ein allenfalls bis dahin über die Leitung 12 an die Platte 1 angelegter Unterdruck (zum Festhalten der Glasscheibe 13 in der vorgegebenen Endstellung) aufgehoben. Die Platte 2 wird mit der an ihr festgehaltenen Glasscheibe 13 in die in Fig. 5 gezeigte Stellung zurückbewegt.As soon as the glass pane 13 reaches its predetermined end position has, the adjustable plate 2 is advanced until them with their surface facing the plate 1 on the glass pane 13 is present. Once this is done, the plate will 2 facing the space 8 between the plates 1 and 2 Side has openings, via a line 12 ' Vacuum applied and at most until then via the Line 12 applied to the plate 1 vacuum (to hold the glass pane 13 in the predetermined end position). The plate 2 is with the glass sheet held on it 13 moved back into the position shown in Fig. 5.

    Als nächster Schritt wird die zweite Glasplatte 11 mit einem auf ihr angesetztem Abstandhalter 14 in den Raum 8 zwischen den Platten 1 und 2 bis in die vorgegebene Endstellung transportiert.The next step is the second glass plate 11 with a on her spacer 14 in the space 8 between the plates 1 and 2 transported to the predetermined end position.

    Durch Betätigen der Druckmittelmotore 5 und 6 wird nun die bewegliche Platte 2 mit der an ihr gehaltenen Glasscheibe 13 in Richtung auf die feststehende Platte 1 zu vorgeschoben bis die Glasscheibe 13 knapp vor den Abstandhalter 14 auf der Glasplatte 11 liegt (Abstand wenige mm). Diese Stellung zeigt Fig. 6, in der erkennbar ist, daß die Glasscheibe 13 den Abstandhalter 14 an keiner Stelle berührt.By actuating the pressure medium motors 5 and 6, the movable Plate 2 with the glass pane 13 held on it Directed towards the fixed plate 1 until the Glass pane 13 just before the spacer 14 on the glass plate 11 lies (distance a few mm). This position is shown in Fig. 6, in which it can be seen that the glass pane 13 is the spacer 14 never touched.

    Sobald diese Stellung erreicht worden ist, werden die Dichteinrichtungen 30 und 31 neben dem Paket aus dem Glasscheiben 11 und 13 und dem Abstandhalter 14 angeordnet.As soon as this position has been reached, the sealing devices 30 and 31 next to the package from the glass panes 11 and 13 and the spacer 14 are arranged.

    Nun kann mit dem eigentlichen Gastausch begonnen werden, bei dem durch den Bandförderer 9 Schwergas eingeleitet und Luft bzw. Luft-Gas-Gemisch abgezogen wird, wobei das Abziehen von Luft bzw. Luft-Gas-Gemisch durch Abpumpen unterstützt werden kann.Now the actual gas exchange can be started at which is introduced by the belt conveyor 9 heavy gas and air or air-gas mixture is withdrawn, the withdrawal of Air or air-gas mixture are supported by pumping can.

    Beim Einleiten von Schwergas bildet sich im Raum 8 zwischen den Platten 1 und 2, der seitlich durch die Dichteinrichtungen 30 und 31 begrenzt ist, ein Gassee 160 (Fig. 3) aus, dessen Grenzfläche 161 während des Füllvorganges nach oben wandert und dabei Luft nach oben aus dem Raum 8 zwischen den Glasscheiben 13 und 11 verdrängt, wie dies in Fig. 3 durch die Pfeile 162 symbolisiert ist.When heavy gas is introduced, space 8 forms between the plates 1 and 2, the side through the sealing devices 30 and 31 is limited, a Gassee 160 (Fig. 3), the Interface 161 migrates upwards during the filling process and thereby air upwards from space 8 between the glass panes 13 and 11 displaced, as shown in Fig. 3 by the Arrows 162 is symbolized.

    Insbesondere bei größeren Isolierglasscheiben 10 kann Schwergas durch den Bandförderer 9 hindurch auch an mehreren Stellen gleichzeitig zugeführt werden, wie dies durch die Pfeile 156 und 157 in Fig. 3 symbolisiert ist.Heavy gas in particular can be used with larger insulating glass panes 10 through the belt conveyor 9 also in several places can be fed simultaneously as indicated by arrows 156 and 157 is symbolized in FIG. 3.

    Sobald im Inneren der Isolierglasscheibe 10 der gewünschte Füllgrad (für Schallschutz etwa 50 %, für Vollwärmeschutz wenigstens 90 % Schwergas im Inneren der Isolierglasscheibe 10) erreicht worden ist, wird die Schwergaszufuhr unterbrochen.As soon as inside the insulating glass pane 10 the desired one Degree of filling (about 50% for sound insulation, for full heat protection at least 90% heavy gas inside the insulating glass pane 10) has been reached, the heavy gas supply is interrupted.

    Wenn die Vorrichtung mit den Platten 1 und 2 als Presse für das Planpressen von Isolierglasscheiben 10 ausgelegt ist, kann die Isolierglasscheibe 10 auch gleich verpreßt werden. Mögliche Konstruktionen für eine solche Presse und des Antriebes zum Bewegen der beweglichen Preßplatte 2 sind in der DE 31 30 645 Al und der am 15.06.1990 bekanntgemachten AT-A 2956/87 beschrieben. Die dort beschriebenen Antriebe (Zahnstangen-Ritzel-Antriebe oder Spindel-Antriebe) können an Stelle der Druckmittelzylinder 5 und 6 eingesetzt werden.If the device with the plates 1 and 2 as a press for the flat pressing of insulating glass panes 10 is designed, can the insulating glass pane 10 are also pressed immediately. Possible Constructions for such a press and the drive for moving the movable press plate 2 are in DE 31 30th 645 Al and AT-A 2956/87, published on June 15, 1990 described. The drives described there (rack and pinion drives or spindle drives) can be used instead of Pressure cylinder 5 and 6 are used.

    Nachdem der Preßvorgang beendet ist, wird die bewegliche Platte 2 von der Platte 1 weg bewegt und die fertig verpreßte, mit Schwergas gefüllte Isolierglasscheibe 10, bestehend aus den beiden Glasscheiben 11 und 13 und dem dazwischengefügten Abstandhalter 14, wird vom Bandförderer 9 beispielsweise zu einer Versiegelungsstation transportiert.After the pressing process is finished, the movable plate 2 moved away from the plate 1 and the finished pressed, with Heavy gas filled insulating glass pane 10, consisting of the two glass panes 11 and 13 and the spacer inserted between them 14, the belt conveyor 9, for example transported to a sealing station.
