Abstract

In order to fill the interior of an insulating glass pane (1) with argon, during pressing of the insulating glass pane (1) one glass pane is held in the region of a corner (2) at a distance from the spacer frame by holding this glass pane at a distance from the spacer frame by swivelling a part (12) of the press plate (11) using suction heads (19, 20) provided on this part (12). Inserted through the gap thus formed are a probe (4) for supplying argon and a probe (5) for extracting air from the interior of the insulating glass pane. The probe (4) through which argon is blown into the interior is aligned parallel to the lower horizontal limb of the insulating glass pane (1), and the other probe (5), via which air or air/argon mixture is extracted, has an opening which points obliquely upwards, i.e. away from the other probe (4). As a result, it is possible to produce insulating glass panes (1) having a filling of the interior other than air without it being necessary to bore holes in the spacer frame, the gas exchange taking place such that argon is mixed with the air displaced from the interior only to a very limited extent. <IMAGE>

Description

Die Erfindung betrifft ein Verfahren zum Füllen des Innenraumes von Isolierglasscheibenrohlingen mit einem anderen Gas als Luft, insbesondere mit Argon, wobei in den Innenraum des Isolierglasscheibenrohlinges eine Sonde zum Zuführen des Gases und eine Sonde zum Absaugen von Luft bzw. Luft-Gas-Gemisch aus dem Innenraum des Isolierglasscheibenrohlinges eingeführt werden. Solche Füllgase sind z.B.: Argon oder ein sogenanntes Schwergas, wie Schwefelhexafluorid.The invention relates to a method for filling the interior of insulating glass blanks with a gas other than air, in particular with argon, with a probe for supplying the gas and a probe for extracting air or air-gas mixture from the inside of the insulating glass blank Interior of the insulating glass blank are introduced. Such filling gases are, for example: argon or a so-called heavy gas, such as sulfur hexafluoride.

Für das Füllen des Innenraumes von Isolierglasscheiben mit einem von Luft abweichenden Gas, z.B. mit Argon oder mit Schwefelhexafluorid sind schon die verschiedensten Techniken vorgeschlagen worden. Bei einer der bekannten Arbeitsweisen werden Sonden zum Zuführen des Gases, das die Luft im Innenraum der Isolierglasscheibe ersetzen soll, und eine Sonde zum Absaugen von Luft- bzw. Luft-Gas-Gemisch durch im Abstandhalter zwischen den Glastafeln der Isolierglasscheibe vorgesehene Bohrungen eingeführt und dann der Gastausch ausgeführt. Diese Arbeitstechnik ist insoferne nachteilig, als im Abstandhalter Löcher gebohrt werden müssen, die dann nach beendetem Gastausch wieder dicht verschlossen werden müssen. Derartige Arbeitstechniken sind beispielsweise aus der DE-PS 30 25 122, der DE-OS 31 17 256 oder der US-PS 2 756 467 bekannt. Verfahren zum Füllen von Isolierglasscheiben mit Sondergas sind auch aus der EP-A-276 647 und 324 333 bekannt, welche Verfahren das Herstellen und nachträgliche Verschließen von Öffnungen im Abstandhalterrahmen umfassen.For filling the interior of insulating glass panes with a gas other than air, e.g. A wide variety of techniques have already been proposed with argon or with sulfur hexafluoride. In one of the known methods of operation, probes for supplying the gas which is to replace the air in the interior of the insulating glass pane and a probe for extracting air or air-gas mixture are introduced through bores provided in the spacer between the glass panels of the insulating glass pane and then the gas exchange carried out. This working technique is disadvantageous in that holes have to be drilled in the spacer, which then have to be sealed again after the gas exchange has ended. Such working techniques are known for example from DE-PS 30 25 122, DE-OS 31 17 256 or US-PS 2 756 467. Methods for filling insulating glass panes with special gas are also known from EP-A-276 647 and 324 333, which methods include the production and subsequent closing of openings in the spacer frame.

Bei einer anderen Arbeitstechnik wurde vorgeschlagen, den Umstand auszunützen, daß Isolierglasscheiben nach dem Zusammenstellen der Scheibenpakete in Vorrichtungen, wie sie beispielsweise aus der DE-PS 28 20 630 oder der DE-PS 31 22 736 bekannt sind, am unteren, horizontalen Rand des zusammengestellten Scheibenpaktes zwischen dem Abstandhalterrahmen, der auf einer der beiden Glasscheiben angesetzt ist und der an diesen angelehnten (Deck-)Gastafel einen Spalt aufweisen. Es wurde vorgeschlagen, durch diesen Spalt das Gas, das die Luft im Innenraum der Isolierglasscheibe ersetzen soll, einzuführen (AT-PS 368 985).In another working technique, it was proposed to take advantage of the fact that insulating glass panes after assembling the pane packages in devices such as those described in DE-PS 28 20 630 or DE-PS 31 22 736 are known, on the lower, horizontal edge of the compiled pane pact between the spacer frame, which is attached to one of the two glass panes and which have a gap on the (top) gas panel. It was proposed to introduce the gas that is to replace the air in the interior of the insulating glass pane through this gap (AT-PS 368 985).

Eine Arbeitsweise, bei welcher der Gastausch durch einen Spalt im Bereich des unteren horizontalen Schenkels eines Abstandhalterrahmens erfolgen soll, ist aus der DE-OS 34 02 323 bekannt.A method of operation in which the gas exchange is to take place through a gap in the region of the lower horizontal leg of a spacer frame is known from DE-OS 34 02 323.

Es ist auch bekannt, eine Sonde zum Gasaustausch in einen Isolierglasscheibenrohling in eine Öffnung zwischen Abstandhalterrahmen und einer der Glasscheiben des Isolierglasscheibenrohlinges einzuführen, wobei dieser Abstand im Bereich seiner Seitenkante des Isolierglasscheibenrohlinges dadurch erzeugt wird, daß die eine Glasscheibe von mehreren Saugköpfen unter Ausbildung einer Wölbung vom Abstandhalterrahmen abgehoben wird. Diese Verfahrensweise ist insoferne nachteilig, als eine nach mehreren Richtungen verlaufende Krümmung entsteht und so eine erhöhte Bruchgefahr der abgehobenen Glasscheibe entsteht. Außerdem sind für das Abheben der Glasscheibe vom Abstandhalterrahmen hohe Kräfte erforderlich.It is also known to insert a probe for gas exchange in an insulating glass blank in an opening between the spacer frame and one of the glass panes of the insulating glass blank, this distance being produced in the region of its side edge of the insulating glass blank by the one glass pane being formed by a plurality of suction heads with the formation of a curvature from Spacer frame is lifted off. This procedure is disadvantageous insofar as a curvature which extends in several directions arises and thus there is an increased risk of the lifted-off glass pane breaking. In addition, high forces are required to lift the glass pane from the spacer frame.

Der Erfindung liegt die Aufgabe zugrunde, das Verfahren der eingangs genannten Gattung in der Weise zu verbessern, daß nicht nur der eigentliche Gastausch einfach und rasch erfolgt sondern daß auch das Herstellen und nachträgliche Verschließen von Löchern im Abstandhalterrahmen vermieden wird, ohne daß die Nachteile der oben geschilderten Verfahren, bei welchen der Gasaustausch über einen Spalt im Bereich des unteren horizontalen Schenkels des Abstandhalterrahmens erfolgt, auftreten.The invention has for its object to improve the method of the type mentioned in such a way that not only the actual gas exchange takes place easily and quickly, but also that the production and subsequent closing of holes in the spacer frame is avoided without the disadvantages of the above described methods in which the gas exchange takes place via a gap in the region of the lower horizontal leg of the spacer frame.

Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß der Isolierglasscheibenrohling nach dem Zusammenstellen des Scheibenpaketes in einer Presse gepreßt wird, daß im Bereich einer Ecke eine Scheibe des Isolierglasscheibenrohlings im Abstand vom Abstandhalterrahmen gehalten wird, und daß beide Sonden im Bereich dieser Ecke in den Innenraum des Isolierglasscheibenrohlinges eingeführt werden.According to the invention, this object is achieved in that the insulating glass pane blank is pressed in a press after assembling the pane package, that a pane of the insulating glass pane blank is held at a distance from the spacer frame in the area of a corner, and that both probes are introduced into the interior of the insulating glass pane blank in the area of this corner.

Dadurch, daß beim erfindungsgemäßen Verfahren beim Verpressen des aus der Zusammenbaustation kommenden Scheibenpaketes zu einem Isolierglasscheibenrohling im Bereich einer Ecke - bevorzugt geht man so vor, daß man das Scheibenpaket im wesentlichen vertikal stehend verpreßt und die eine Scheibe im Bereich einer der unteren Ecken im Abstand vom Abstandhalterrahmen hält - offengehalten wird, können die Sonden für den Gastausch ohne die Nachteile der oben geschilderten, bekannten Arbeitsweisen auch ohne die Herstellung von Löchern im Abstandhalterrahmen eingeführt werden.The fact that in the method according to the invention, when the pane package coming from the assembly station is pressed to form an insulating glass pane blank in the area of a corner, the preferred procedure is to compress the pane package essentially vertically and one pane in the area of one of the lower corners at a distance from Spacer frame holds - is kept open, the probes for gas exchange can be introduced without the disadvantages of the known procedures described above, even without the production of holes in the spacer frame.

Der Gastausch erfolgt besonders rasch und einfach, wenn so vorgegangen wird, daß aus der Sonde zum Zuführen von Gas ein im wesentlichen parallel zum unteren, horizontalen Schenkel des Abstandhalterrahmens ausgerichteter Gasstrom in den Innenraum des Isolierglasscheibenrohlinges geblasen wird. Bei dieser Arbeitsweise wird eine Vermischung des zugeführten Gases mit dem abströmenden Luft- bzw. Luft-Gas-Gemisch weitestgehend verhindert, da sich das Gas, welches die Luft im Scheibeninnenraum ersetzen soll, in breiter Front von der der Einfüllstelle gegenüberliegenden Seite auf die Einfüllseite zu fortschreitend bewegt und dabei das Luft-Gas-Gemisch bzw. die Luft nach und nach unter Verdichtung zur Absaugsonde hin drückt.The gas exchange takes place particularly quickly and easily if the procedure is such that a gas stream which is aligned essentially parallel to the lower, horizontal leg of the spacer frame is blown into the interior of the insulating glass blank from the probe for supplying gas. With this method of operation, mixing of the supplied gas with the outflowing air or air-gas mixture is largely prevented, since the gas which is intended to replace the air in the interior of the pane widens from the side opposite the filling point to the filling side moving progressively and gradually pushing the air-gas mixture or the air towards the suction probe, compressing it.

Bei einer Variante des erfindungsgemäßen Verfahrens wird so vorgegangen, daß man Luft bzw. Luft-Gas-Gemisch über die in den Innenraum des Isolierglasscheibenrohlinges eingeführte Sonde in einem Ausmaß abzieht, daß während des Gastausches im Innenraum des Isolierglasscheibenrohlinges ein Druck herrscht, der höher ist als der Druck in der Umgebung. Diese Arbeitsweise hat den Vorteil, daß besondere Abdichtungsmaßnahmen entbehrlich sind und dennoch keine Luft in den Innenraum des Isolierglasscheibenrohlinges eingesaugt wird, wobei die dabei entstehenden Verluste vernachläßigbar sind, insbesondere wenn der Innenraum des Isolierglasscheibenrohlinges mit Argon oder einem ähnlich billigen Gas gefüllt wird.In a variant of the method according to the invention, the procedure is such that air or air-gas mixture is introduced into the interior of the insulating glass blank withdrawn inserted probe to an extent that there is a pressure in the interior of the insulating glass blank during the gas exchange, which is higher than the pressure in the environment. This procedure has the advantage that special sealing measures are unnecessary and yet no air is sucked into the interior of the insulating glass blank, the resulting losses being negligible, especially if the interior of the insulating glass blank is filled with argon or a similarly cheap gas.

Nach Beendigung des Gastausches kann bei dem erfindungsgemäßen Verfahren so vorgegangen werden, daß der Isolierglasscheibenrohling auch im Bereich der offen gehaltenen Ecke verpreßt wird.After the gas exchange has ended, the process according to the invention can be carried out in such a way that the insulating glass blank is also pressed in the area of the open corner.

Gemäß einer anderen Variante des erfindungsgemäßen Verfahrens ist vorgesehen, daß die Sonde zum Absaugen von Luft bzw. Luft-Gas-Gemisch mit schräg nach oben gerichteter und von der Sonde zum Zuführen von Gas wegweisender Mündung Luft bzw. Luft-Gas-Gemisch aus dem Innenraum des Isolierglasscheibenrohlinges absaugt. Bei dieser Ausführungsform wird zuverlässig verhindert, daß das durch die eine Sonde eingeführte Gas (beispielsweise Argon) durch die andere Sonde gleich wieder abgesaugt wird.According to another variant of the method according to the invention, it is provided that the probe for suction of air or air-gas mixture with an obliquely upward and air-or-gas mixture mouth pointing away from the probe for supplying gas from the interior of the insulating glass blank. In this embodiment, it is reliably prevented that the gas introduced by one probe (for example argon) is immediately sucked out again by the other probe.

Da beim erfindungsgemäßen Verfahren die Sonden nicht durch Bohrungen, sondern durch den offenen Bereich im Eck in den Innenraum des Isolierglasscheibenrohlinges eingeführt werden, können diese beim erfindungsgemäßen Verfahren auch, wenn die Sonden in unterschiedliche Richtungen, z.B. voneinander wegweisen, gleichzeitig in den Innenraum der Isolierglasscheibe eingeführt werden.Since in the method according to the invention the probes are not introduced through holes, but through the open area in the corner into the interior of the insulating glass blank, they can also be used in the method according to the invention if the probes are in different directions, e.g. point away from each other, are simultaneously introduced into the interior of the insulating glass pane.

Die Menge an Gas, die beim erfindungsgemäßen Verfahren verwendet wird, kann einfach dadurch bestimmt werden, daß man den Gastausch so lange fortsetzt, bis im über die eine Sonde abgesaugten Luft-Gas-Gemisch der Anteil an Luft einen vorgegebenen Wert unterschreitet. Alternativ oder ergänzend kann man das Volumen des Innenraumes des Isolierglasscheibenrohlinges berechnen und in den Innenraum der Isolierglasscheibe eine Menge Gas in den Innenraum einführen, die dem berechneten Volumen vermehrt um einen vorgegebenen Bruchteil dieses Volumens entspricht.The amount of gas used in the process according to the invention can be determined simply by continuing the gas exchange until the proportion of the air-gas mixture extracted via the one probe Air falls below a predetermined value. Alternatively or additionally, the volume of the interior of the insulating glass blank can be calculated and a quantity of gas can be introduced into the interior of the insulating glass pane that corresponds to the calculated volume by a predetermined fraction of this volume.

Die Erfindung betrifft weiters eine Vorrichtung, die zur Durchführung des erfindungsgemäßen Verfahrens besonders geeigent ist.The invention further relates to a device which is particularly suitable for carrying out the method according to the invention.

Erfindungsgemäß zeichnet sich die Vorrichtung zur Durchführung des Verfahrens mit zwei Preßplatten, die zum Verpressen des Isolierglasrohlinges einander angenähert werden können, mit einer Sonde zum Einleiten von Gas in den Raum zwischen den Glasscheiben des Isolierglasrohlinges und mit einer Sonde zum Absaugen von Luft bzw. Luft-Gas-Gemisch aus dem Raum zwischen den Glasscheiben des Isolierglasscheibenrohlinges, welche Sonden auf einem Träger relativ zum zwischen den Platten der Presse gehaltenen Isolierglasscheibenrohling beweglich sind, dadurch aus, daß im Bereich einer Ecke einer der Platten der Presse an die eine der Glasscheiben des Isolierglasscheibenrohlinges angreifende Vorrichtung, vorzugsweise wenigstens ein an der Außenfläche der Glasscheibe anlegbarer Saugkopf, befestigt ist und daß der Bereich der Platte, in welcher die Greifvorrichtung befestigt ist, mit dem übrigen Teil der Platte der Preßvorrichtung verschwenkbar verbunden ist.According to the invention, the device for carrying out the method is characterized by two pressure plates which can be approximated to one another for pressing the insulating glass blank, with a probe for introducing gas into the space between the glass panes of the insulating glass blank and with a probe for extracting air or air. Gas mixture from the space between the glass panes of the insulating glass blank, which probes are movable on a carrier relative to the insulating glass blank held between the plates of the press, in that in the area of a corner of one of the plates of the press attacking one of the glass panes of the insulating glass blank Device, preferably at least one suction head which can be placed on the outer surface of the glass pane, is fastened and that the region of the plate in which the gripping device is fastened is pivotably connected to the remaining part of the plate of the pressing device.

Vorteilhafte Ausführungsformen der erfindungsgemäßen Vorrichtung sind Gegenstand der Unteransprüche 12 bis 17.Advantageous embodiments of the device according to the invention are the subject of dependent claims 12 to 17.

Weitere Einzelheiten und Merkmale der Erfindung ergeben sich aus der nachstehenden Beschreibung, in der auf die angeschlossene Zeichnung Bezug genommen wird. In den

Further details and features of the invention will become apparent from the following description in which reference is made to the attached drawing. In the
  • 1 to 3 are three phases in the gas exchange, in which Air in the interior of an insulating glass blank is replaced by a gas, shown and
  • 4 schematically shows an apparatus for performing the method according to the invention.

Ein Scheibenpaket 1, das aus einer Zusammenbaustation kommt, wobei die Deckscheibe nur oben am Abstandhalterrahmen anlehnt und unten einen Abstand von diesem aufweist, wird in eine Presse gefördert. In der Presse (z.B. eine der aus der DE-PS 31 30 645 bekannten Bauart) wird das Scheibenpaket verpreßt und dabei die Deckscheibe in einer unteren Ecke 2 des Scheibenpaktes, vorzugsweise der vorderen, unteren Ecke im Abstand vom Abstandhalterrahmen gehalten und/oder vom Abstandhalterrahmen abgehoben bzw. zum Abstandhalterrahmen auf Abstand gehalten.A disk package 1, which comes from an assembly station, the cover disk leaning only against the spacer frame at the top and being at a distance from the bottom, is conveyed into a press. In the press (for example, one of the types known from DE-PS 31 30 645), the disk package is pressed and the cover disk is held in a lower corner 2 of the disk package, preferably the front, lower corner, at a distance from the spacer frame and / or from the spacer frame lifted off or held at a distance from the spacer frame.

Durch den Spalt im Bereich der einen unteren Ecke 2, der also beim Verpressen des Isolierglasscheibenrohlinges offen bleibt, werden zwei an einem gewinkelten Träger 3 nahe beieinander montierte Sonden 4 und 5, über die der Gastausch erfolgt, in den Innenraum des Isolierglasscheibenrohlinges eingeführt. Dabei ist die das Sondergas (z.B. Argon) zuführende Sonde 4 horizontal ausgerichet und bläst den Gasstrom mit hoher Geschwindigkeit parallel zum unteren, horizontalen Schenkel des Abstandhalterrahmens in den Zwischenraum zwischen den Glasscheiben ein.Through the gap in the area of a lower corner 2, which thus remains open when pressing the insulating glass blank, two probes 4 and 5, which are mounted close to one another on an angled support 3 and via which the gas exchange takes place, are introduced into the interior of the insulating glass blank. The probe 4 supplying the special gas (e.g. argon) is aligned horizontally and blows the gas flow into the space between the glass panes at high speed parallel to the lower, horizontal leg of the spacer frame.

Die zweite, am gewinkelten Träger 3, der von außen an die Ecke 2 des Isolierglasscheibenrohlinges 1, gegebenenfalls unter Zwischenfügung einer Dichtung (elastischer Schaumstoff) angelegt wird, montierte Sonde 5 weist eine Mündung auf, die schräg nach oben gerichtet ist, und dient zum Absaugen von aus dem Innenraum des Isolierglasscheibenrohlinges verdrängter Luft bzw. Luft-Gas-Gemisch.The second probe 5, which is mounted on the angled support 3 and which is applied from the outside to the corner 2 of the insulating glass blank 1, optionally with the interposition of a seal (elastic foam), has an opening which is directed obliquely upwards and is used for suction of air or air-gas mixture displaced from the interior of the insulating glass blank.

Der Gastausch wird so durchgeführt, daß im Innenraum des Isolierglasscheibenrohlinges stets ein wenigstens kleiner Überdruck herrscht, so daß kontinuierlich Gas getauscht werden kann und allenfalls überschüssige Luft bzw. Gas-Luft-Gemisch aus dem Innenraum verdrängt wird, was nicht stört, da das Füllgas, insbesondere wenn es sich um Argon handelt, nicht teuer ist.The gas exchange is carried out in such a way that there is always at least a small one in the interior of the insulating glass blank Overpressure prevails, so that gas can be exchanged continuously and at most excess air or gas-air mixture is displaced from the interior, which is not a problem since the filling gas, especially if it is argon, is not expensive.

Durch das Einblasen von Füllgas mit hoher Geschwindigkeit parallel zum unteren horizontalen Schenkel des Abstandhalterrahmens folgt der Gasstrom den Innenumfang des Abstandhalterrahmens und verdichtet sich zur Mitte hin, so daß nach und nach Luft in einem zunehmend kleiner werdenden Bereich verdichtet und aus dem Innenraum des Isolierglasscheibenrohlinges verdrängt wird, wie dies in den Fig. 1 bis 3 durch die "Front" 6 zwischen dem Füllgas und der Luft angedeutet ist.By blowing in filling gas at high speed parallel to the lower horizontal leg of the spacer frame, the gas flow follows the inner circumference of the spacer frame and compresses towards the center, so that air is gradually compressed in an increasingly smaller area and displaced from the interior of the insulating glass blank , as indicated in FIGS. 1 to 3 by the "front" 6 between the filling gas and the air.

Die Steuerung des Gasfüllens erfolgt entweder durch Messen des Restsauerstoffgehaltes im aus dem Innenraum des Isolierglasscheibenrohlinges abgezogenen Gas-Luft-Gemisch, durch Bestimmung der Zusammensetzung des Luft-Gas-Gemisches im Innenraum des Isolierglasscheibenrohlinges und/oder durch Ermittlen (Berechnen) des Volumens des Scheibeninnenraums und Zuführen einer entsprechend dosierten Gasmenge, wobei ein gewisser Verlust wegen des herrschenden Überdrucks dadurch berücksichtigt wird, daß die berechnete Volumensmenge um einen z.B. empirisch festgelegten Bruchteil vergrößert wird.The gas filling is controlled either by measuring the residual oxygen content in the gas-air mixture drawn from the interior of the insulating glass blank, by determining the composition of the air-gas mixture in the interior of the insulating glass blank and / or by determining (calculating) the volume of the interior of the pane and Supply of a correspondingly metered amount of gas, a certain loss due to the prevailing overpressure being taken into account by the fact that the calculated volume amount by an example empirically determined fraction is increased.

Vorteile des erfindungsgemäßen Verfahrens bestehen darin, daß kontinuierlich gearbeitet werden kann und nicht ständig zwischen Einblasen und Absaugen gewechselt werden muß. Auch entfallen bei der erfindungsgemäßen Arbeitsweise das Bohren und nachträgliche Verschließen von Öffnungen im Abstandhalterrahmen, durch welche die Sonden einzuführen sind. Ein weiterer Vorteil besteht darin, daß die Vermischung zwischen zugeführtem Gas und Luft im Innenraum des Isolierglasscheibenrohlinges in Grenzen gehalten wird, da eine derartige Vermischung nur in beschränktem Ausmaß eintritt.Advantages of the method according to the invention are that it is possible to work continuously and does not have to be constantly switched between blowing and suctioning. In addition, the drilling and subsequent closing of openings in the spacer frame through which the probes are to be inserted are omitted in the working method according to the invention. Another advantage is that the mixing between supplied gas and air in the interior of the insulating glass blank is kept within limits, since such mixing is limited Extent occurs.

Eine in Fig. 4 schematisch angedeutete Presse besitzt zwei Preßplatten 10 und 11, die relativ zueinander beweglich sind, wie dies für Pressen zum Verpressen von Isolierglasrohlingen an sich bekannt ist. Die Konstruktion der Presse mit den Platten 10 und 11 und der Antrieb zum Verstellen der beweglichen Preßplatte, z.B. der Platte 11, kann eine Konstruktion besitzen wie sie an sich bekannt ist. Beispiele für im vorliegenden Zusammenhang verwendbare bekannte Preßvorrichtungen sind in der AT-PS 385 499 oder in der am 15. Juni 1990 bekanntgemachten österr. Patentanmeldung A 2956/87 beschrieben. Wie aus Fig. 4 ersichtlich, ist nur ein unterer Eckbereich 12 der Preßplatte 11 gegenüber der Preßplatte 11 verschwenkbar und mit dieser über Scharniere 13 und 14 verbunden. Zum Verschwenken des Eckbereiches 12 der Preßplatte 11 ist ein Druckmittelzylinder 15 vorgesehen, der einerseits bei 16 mit der Preßplatte 11 und anderseits über einen von dem Eckbereich 12 abstehenden Ansatz 17 mit diesem verbunden ist. Durch Betätigen des Druckmittelzylinders 15 kann der Eckbereich 12 in Richtung des Doppelpfeiles 18 (Fig. 4) hin und her verschwenkt werden.A press schematically indicated in Fig. 4 has two press plates 10 and 11 which are movable relative to each other, as is known per se for presses for pressing insulating glass blanks. The construction of the press with the plates 10 and 11 and the drive for moving the movable press plate, e.g. the plate 11 can have a construction as is known per se. Examples of known pressing devices which can be used in the present context are described in AT-PS 385 499 or in Austrian patent application A 2956/87, which was published on June 15, 1990. As can be seen from FIG. 4, only a lower corner region 12 of the press plate 11 can be pivoted with respect to the press plate 11 and is connected to the latter via hinges 13 and 14. For pivoting the corner region 12 of the press plate 11, a pressure medium cylinder 15 is provided, which is connected on the one hand at 16 to the press plate 11 and on the other hand via an extension 17 projecting from the corner region 12. By actuating the pressure medium cylinder 15, the corner region 12 can be pivoted back and forth in the direction of the double arrow 18 (FIG. 4).

Wie aus Fig. 4 ersichtlich, sind im Eckbereich 12 der Preßplatte 11 im gezeigten Ausführungsbeispiel zwei Saugköpfe 19 und 20 vorgesehen, die über Leitungen 21, 22 mit Unterdruck beaufschlagt werden können. Die Saugköpfe 19 und 20 legen sich an die eine Glasscheibe des Isolierglasscheibenrohlinges 1 an, so daß in dessen Ecke 2 durch Betätigen des Druckmittelzylinders 15 und Verschwenken des Eckbereiches 12 der Preßplatte 11 die eine Glasscheibe vom zwischen den beiden Glasscheiben des Isolierglas-scheibenrohlinges 1 befindlichen Abstandhalterrahmen abgehoben wird.As can be seen from FIG. 4, two suction heads 19 and 20 are provided in the corner region 12 of the pressure plate 11 in the exemplary embodiment shown, and can be subjected to negative pressure via lines 21, 22. The suction heads 19 and 20 lie against the one glass pane of the insulating glass blank 1, so that in its corner 2 by actuating the pressure cylinder 15 and pivoting the corner region 12 of the press plate 11, the one glass pane from the spacer frame 1 located between the two glass panes of the insulating glass blank 1 is lifted off.

Sobald dies geschehen ist, wird in die so gebildete Öffnung die Sonde 4 und die Sonde 5 eingeführt, wobei sich der winkelförmige Träger 3 an den Isolierglasscheibenrohling 1 im Bereich der Ecke 1' desselben, wie oben erwähnt, an den Außenumfang des Isolierglasscheibenrohlinges 1 anlegt. Sobald der Gasaustausch wie weiter oben beschrieben erfolgt ist, wird der Träger 3 mit den Sonden 4 und 5 wieder entfernt, wozu eine nicht näher gezeigte Betätigungsvorrichtung für die Halterung 3 vorgesehen ist, und der Druckmittelzylinder 15 so betätigt, daß der Eckbereich 12 der Platte 11 wieder zurückschwenkt und so der Isolierglasscheibenrohling auch im Bereich der zunächst noch offenen Ecke 2 verpreßt.As soon as this has been done, the probe 4 and the probe 5 are inserted into the opening thus formed, whereby the angular support 3 bears on the insulating glass blank 1 in the area of the corner 1 'thereof, as mentioned above, on the outer circumference of the insulating glass blank 1. As soon as the gas exchange has taken place as described above, the carrier 3 with the probes 4 and 5 is removed again, for which purpose an actuating device (not shown) for the holder 3 is provided, and the pressure medium cylinder 15 is actuated so that the corner region 12 of the plate 11 swings back again and thus the insulating glass blank is pressed in the area of the initially still open corner 2.

Nachdem der Preßvorgang und der Gasaustausch so beendet ist, wird die Presse geöffnet, indem die Preßplatte 11 von der Preßplatte 10 wegbewegt wird und der so mit Gas, beispielsweise Argon, gefüllte Isolierglasscheibenrohling 1 aus der Presse gefördert und beispielsweise einer Versiegelungsstation zugeführt.After the pressing process and the gas exchange have ended, the press is opened by moving the pressing plate 11 away from the pressing plate 10 and conveying the insulating glass blank 1 filled with gas, for example argon, from the press and, for example, to a sealing station.
