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, die aus wenigstens zwei Glasscheiben und einem zwischen diesen angeordneten Abstandhalterrahmen bestehen, mit einem anderen Gas als Luft, insbesondere mit Argon, wobei eine spaltförmige Öffnung für das Zuführen von Gas und das Abziehen von Luft bzw. Luft-Gas-Gemisch gebildet wird, indem eine der Glasscheiben des Isolierglasscheibenrohlings unter elastischem Biegen dieser Glasscheibe im Abstand vom Abstandhalterrahmen gehalten wird, wenn der Isolierglasscheibenrohling nach dem Zusammenstellen des Scheibenpaketes in einer Presse zwischen Preßplatten im wesentlichen vertikal stehend gepreßt wird, wobei durch die so gebildete, spaltförmige Öffnung in den Innenraum des Isolierglasscheibenrohlings Gas eingeblasen und Luft bzw. Luft-GasGemisch aus dem Innenraum des Isolierglasscheibenrohlings abgezogen wird (WO 89/11021).The invention relates to a method for filling the interior of insulating glass sheet blanks consisting of at least two Glass panes and a spacer frame arranged between them exist with a gas other than air, in particular with argon, with a slit-shaped opening for the Supply of gas and extraction of air or air-gas mixture is formed by one of the glass panes of the insulating glass blank with elastic bending of this glass pane is kept at a distance from the spacer frame if the insulating glass blank after assembling the Disc packs in a press between press plates essentially is pressed vertically, whereby by the so formed, gap-shaped opening in the interior of the insulating glass blank Blown in gas and air or air-gas mixture from the interior of the insulating glass blank is subtracted (WO 89/11021).

Solche Füllgase sind z.B. Argon oder ein sogenanntes Schwergas, wie Schwefelhexafluorid.Such filling gases are e.g. 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-C 30 25 122, der DE-A 31 17 256 oder der US-A 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. with argon or with Sulfur hexafluoride is a wide variety of techniques been proposed. In one of the well-known ways of working become probes to supply the gas that the air inside to replace the insulating glass pane, and a probe for Aspiration of air or air-gas mixture by in the spacer provided between the glass sheets of the insulating glass pane Drilled holes and then the gas exchange carried out. This technique is disadvantageous insofar as in the spacer Holes must be drilled, which are then finished Gas exchange must be sealed again. Such Working techniques are for example from DE-C 30 25 122, DE-A 31 17 256 or US-A 2 756 467. method for filling insulating glass panes with special gas are also out EP-A-276 647 and 324 333 known which methods the Manufacture and subsequent closing of openings in the Include spacer frames.

Bei einer anderen Arbeitstechnik wurde vorgeschlagen, den Umstand auszunützen, daß Isolierglasscheiben nach dem Zusammenstellen der Scheibenpakete in Vorrichtungen, wie sie beispielsweise aus der DE-C 28 20 630 oder der DE-C 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 Glastafel einen Spalt aufweisen. Es wurde vorgeschlagen, durch diesen Spalt das Gas, das die Luft im Innenraum der Isolierglasscheibe ersetzen soll, einzuführen (AT-B 368 985).In another working technique it was proposed that Take advantage of the fact that insulating glass panes after putting together of the disk packs in devices such as, for example from DE-C 28 20 630 or DE-C 31 22 736 are known at the bottom, horizontal edge of the compiled Disc pact between the spacer frame, the is attached to one of the two glass panes and the on have a gap in this lean glass sheet. It was proposed through this gap the gas that the air in To replace the interior of the insulating glass pane (AT-B 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-A 34 02 323 bekannt.A way of working in which the gas exchange through a gap in the area of the lower horizontal leg of a spacer frame is to be done is known from DE-A 34 02 323.

Es ist auch bekannt (WO 89/11021), eine Öffnung für den Gasaustausch in einen Isolierglasscheibenrohling zwischen dem Abstandhalterrahmen und einer der Glasscheiben des Isolierglasscheibenrohlinges dadurch zu bilden, daß beispielsweise im Bereich einer Seitenkante des Isolierglasscheibenrohlinges die eine Glasscheibe von mehreren Saugköpfen unter Ausbilden einer Wölbung in der Glasscheibe vom Abstandhalterrahmen abgehoben wird. In der WO 89/11021 wird auch vorgeschlagen, die eine Glasscheibe an zwei Ecken vom Abstandhalterrahmen wegzubiegen und so zwei einander diagonal gegenüberliegende Öffnungen zu bilden. Die aus der WO 89/11021 bekannte 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 längs einer Seitenkante oder im Bereich von zwei Ecken hohe Kräfte erforderlich.It is also known (WO 89/11021), an opening for gas exchange in an insulating glass blank between the spacer frame and one of the glass panes of the insulating glass blank to form that, for example, in Area of a side edge of the insulating glass blank a glass sheet from multiple suction heads to form one The curvature in the glass pane is lifted off the spacer frame becomes. WO 89/11021 also proposes the one Bend the glass pane away from the spacer frame at two corners and so two diagonally opposite openings form. The procedure known from WO 89/11021 is disadvantageous in that it extends in several directions Curvature arises, increasing the risk of breakage lifted glass pane is created. Also take off the glass pane from the spacer frame along one High forces are required on the side edge or in the area of two corners.

Der Erfindung liegt die Aufgabe zugrunde, das aus der WO 89/11021 bekannte Verfahren 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 that from WO 89/11021 to improve known methods in such a way that not only the actual exchange of gas is quick and easy but that the manufacture and subsequent sealing of holes in the spacer frame is avoided without the disadvantages of the methods described above, in which gas exchange through a gap in the area of the lower horizontal Leg of the spacer frame occurs.

Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß eine der Glasscheiben des Isolierglasscheibenrohlinges im Bereich nur einer unteren Ecke des Isolierglasscheibenrohlings im Abstand vom Abstandhalterrahmen gehalten wird, während der übrige Teil dieser Glasscheibe durch die Preßplatten in Anlage an den Abstandhalterrahmen gehalten wird, daß mittels einer Sonde Gas mit einer im wesentlichen parallel zum unteren horizontalen Schenkel des Abstandhalterrahmens ausgerichteten Strömungsrichtung in den Innenraum des Isolierglasscheibenrohlings geblasen wird und daß mittels einer Sonde Luft bzw. Luft-Gas-Gemisch durch einen Bereich der spaltförmigen Öffnung aus dem Innenraum des Isolierglasscheibenrohlings abgezogen wird, der oberhalb des Bereiches der spaltförmigen Öffnung liegt, durch den Gas in den Innenraum des Isolierglasscheibenrohlings eingeblasen wird.According to the invention this object is achieved in that a the glass panes of the insulating glass blank in the area only a lower corner of the insulating glass blank in the Distance from the spacer frame is held during the remaining part of this glass pane through the press plates in plant is held on the spacer frame that gas by means of a probe with an im substantially parallel to the lower horizontal leg of the Spacer frame aligned flow direction in the Interior of the insulating glass sheet blank is blown and that by means of a probe air or air-gas mixture through an area the slit-shaped Opening from the interior of the insulating glass blank is subtracted above the range of gap-shaped opening lies through the gas into the interior of the insulating glass blank is blown.

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, kann der Gastausch ohne die Nachteile der oben geschilderten, bekannten Arbeitsweisen auch ohne das Herstellen von Löchern im Abstandhalterrahmen ausgeführt werden.The fact that in the method according to the invention during pressing of the disc package coming from the assembly station an insulating glass pane blank in the area of a corner - preferred one proceeds in such a way that the disc package essentially vertically pressed and one disc in the area one of the lower corners at a distance from the spacer frame holds - is kept open, the gas exchange can be done without the Disadvantages of the known working methods described above, too performed without making holes in the spacer frame become.

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 ausgerichteten 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 is particularly quick and easy, if so the procedure is followed by a gas feed probe essentially parallel to the lower, horizontal leg of the spacer frame aligned gas flow into the interior of the insulating glass blank is blown. At this Operation is a mixing of the supplied gas largely with the outflowing air or air-gas mixture prevents because the gas, which is the air inside the window should replace, in a broad front from that of the filling point opposite side to the filling side moves while the air-gas mixture or the air gradually presses under compression towards the suction probe.

Bei einer Variante des erfindungsgemäßen Verfahrens wird so vorgegangen, daß man Luft bzw. Luft-Gas-Gemisch aus dem Innenraum des Isolierglasscheibenrohlings in einem Ausmaß abzieht, daß während des Gastausches im Innenraum des Isolierglasscheibenrohlings ein Druck herrscht, der höher ist als der Umgebungsdruck. 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 proceeded that you have air or air-gas mixture from the interior of the insulating glass sheet blank to an extent, that during the gas exchange in the interior of the insulating glass blank there is a pressure higher than that Ambient pressure. This way of working has the advantage of being special Sealing measures are unnecessary and yet none Air is sucked into the interior of the insulating glass blank the losses incurred are negligible are, especially if the interior of the insulating glass blank with argon or a similarly cheap gas is filled.

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 guest exchange has ended with the invention The procedure can be followed so that the insulating glass blank also pressed in the area of the open corner becomes.

Gemäß einer anderen Variante des erfindungsgemäßen Verfahrens ist vorgesehen, daß man zum Abziehen von Luft bzw. Luft-Gas-Gemisch eine Sonde verwendet, die oberhalb der Sonde zum Zuführen von Gas angeordnet ist und die eine schräg nach oben gerichtete und von der Sonde zum Zuführen von Gas wegweisende Mündung zum Abziehen von Luft bzw. Luft-Gas-Gemisch aus dem Innenraum des Isolierglasscheibenrohlings aufweist. 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 one for withdrawing air or air-gas mixture a probe is used to feed above the probe of gas is arranged and the one obliquely upwards directed and pioneering by the gas delivery probe Mouth for withdrawing air or air-gas mixture from the Has interior of the insulating glass blank. At this Embodiment is reliably prevented by the a gas introduced through the probe (e.g. argon) another probe is sucked off immediately.

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 the probes do not pass through in the method according to the invention Holes, but through the open area in the corner in the Interior of the insulating glass blank are introduced, can this also in the inventive method if the Probes in different directions, e.g. point away from each other, at the same time in the interior of the insulating glass pane be introduced.

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 in the invention Procedure used can be done simply by doing so be determined that the gas exchange continues until I'm over the one probe aspirated air-gas mixture the proportion of air falls below a predetermined value. Alternatively or in addition you can change the volume of the interior of the insulating glass sheet blank and in the interior of the insulating glass pane Introduce a lot of gas into the interior that calculated volume increased by a predetermined Fraction of this volume corresponds.

Eine Vorrichtung, die zur Durchführung des erfindungsgemäßen Verfahrens besonders geeignet ist, besitzt zwei Preßplatten, die zum Verpressen des im wesentlichen vertikal stehenden Isolierglasscheibenrohlings einander angenähert werden können, eine Sonde zum Einleiten von Gas in den Raum zwischen den Glasscheiben des Isolierglasscheibenrohlings und eine Sonde zum Abziehen von Luft bzw. Luft-Gas-Gemisch aus dem Innenraum des Isolierglasscheibenrohlings, wobei an einer der Preßplatten eine Saugvorrichtung vorgesehen ist, mit welcher eine der Glasscheiben des Isolierglasrohlings im Abstand vom Abstandhalterrahmen gehalten wird, indem sie unter elastischer Verformung vom Abstandhalterrahmen weggebogen wird. Die Saugvorrichtung ist im Bereich einer unteren Ecke einer der Platten der Presse vorgesehen, wobei der Bereich der Preßplatte, in dem die Saugvorrichtung vorgesehen ist, mit dem übrigen Teil der Preßplatte verschwenkbar verbunden ist.A device to carry out of the method according to the invention in particular is suitable, has two press plates that for pressing the essentially vertically standing insulating glass blank each other can be approximated, a probe for introduction of gas in the space between the glass panes of the insulating glass blank and a probe for extracting air or air-gas mixture from the interior of the insulating glass blank, being on one of the press plates a suction device is provided with which is one of the glass panes of the insulating glass blank at a distance from the spacer frame is held by being under elastic Deformation bent away from the spacer frame becomes. The suction device is in the range lower corner of one of the plates of the press provided the area of the press plate, in which the suction device is provided with the remaining part of the press plate can be pivoted connected is.

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 disc package 1, which consists of an assembly station comes, with the cover plate only on the top of the spacer frame leans on and is at a distance from it at the bottom, is promoted in a press. In the press (e.g. one of the design known from DE-PS 31 30 645) the disc package is pressed and the cover disc in a lower corner 2 of the disc pact, preferably the front, lower corner at a distance from the spacer frame held and / or lifted off the spacer frame or kept 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, the in other words when pressing the insulating glass blank remains open, two are on an angled support 3 Probes 4 and 5 mounted close to each other, via which the Gas exchange takes place in the interior of the insulating glass blank introduced. It is the special gas (e.g. argon) feeding probe 4 aligned horizontally and blows the gas stream in parallel at high speed to the lower, horizontal leg of the spacer frame into the space between the glass panes.

    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 so that in the interior of the Insulating glass blank always at least a small one Overpressure prevails, so that gas is continuously exchanged and possibly excess air or gas-air mixture what is not displaced from the interior bothers because the fill 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 condenses towards the middle, like this that little by little air in an increasingly smaller Area compressed and from the interior of the insulating glass blank is ousted like this in the 1 to 3 through the "front" 6 between the filling gas and is indicated in 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 of the residual oxygen content in the interior of the Insulated glass pane blank drawn off gas-air mixture, 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 Amount of gas, with some loss due to prevailing overpressure is taken into account in that the calculated volume by e.g. empirically specified 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 you can work continuously and not constantly be changed between blowing and suction got to. Also eliminated in the procedure according to the invention drilling and subsequent closing of openings in the spacer frame through which the probes are to be introduced. Another advantage is that the mixing between supplied gas and air in Interior of insulating glass blank in limits is kept, since such mixing is only 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 shown schematically in FIG. 4 has two press plates 10 and 11 which are movable relative to each other are like this for presses for pressing insulating glass blanks is known per se. The construction the press with the plates 10 and 11 and the drive for Adjustment of the movable press plate, e.g. the plate 11, can have a construction as known per se is. Examples of in the present context Known pressing devices that can be used are in AT-PS 385,499 or published in June 15, 1990 Austrian patent application A 2956/87. How from 4, only a lower corner area 12 of the Press plate 11 pivotable relative to the press plate 11 and connected to it via hinges 13 and 14. To the Swiveling the corner region 12 of the press plate 11 is a pressure medium cylinder 15 is provided, on the one hand 16 with the press plate 11 and on the other hand via one of the corner area 12 projecting shoulder 17 connected to this is. By actuating the pressure medium cylinder 15 can the corner region 12 in the direction of the double arrow 18th (Fig. 4) are pivoted back and forth.

    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 Isolierglasscheibenrohlinges 1 befindlichen Abstandhalterrahmen abgehoben wird.As can be seen from FIG. 4, in the corner area 12 Press plate 11 in the embodiment shown two suction heads 19 and 20 provided with lines 21, 22 with Vacuum can be applied. The suction heads 19 and 20 lie against the one glass pane of the insulating glass blank 1 so that in its corner 2 through Actuation of the pressure medium cylinder 15 and pivoting the corner region 12 of the press plate 11, the one glass pane from between the two glass panes of the insulating glass blank 1 spacer frame located becomes.

    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 opening thus formed the probe 4 and the probe 5 inserted, whereby the angular support 3 on the insulating glass blank 1 in the area of the corner 1 'thereof, as mentioned above, to the outer circumference of the insulating glass blank 1 creates. As soon as the gas exchange as described above is carried out, the carrier 3 with the probes 4th and 5 removed again, for which purpose an operating device, not shown is provided for the holder 3, and the pressure cylinder 15 actuated so that the corner area 12 of the plate 11 pivots back and so the Insulating glass sheet blank also in the area of initially still pressed 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 gas exchange ended the press is opened by pressing plate 11 is moved away from the press plate 10 and so with gas, for example argon, filled insulating glass blank 1 funded from the press and, for example, a sealing station fed.
