Definitions
- the invention relates to a method for filling an insulating glass unit with a filling gas, in which the filling gas is introduced into the interior of the insulating glass unit via at least one inlet opening and air or air-gas mixture is sucked out of the interior of the insulating glass unit via at least one additional opening, and in which a pressure is exerted on the outer surfaces of the glass panes of the insulating glass unit to be filled during the filling process, which is greater than the pressure prevailing inside the insulating glass unit during the filling process.
- a method for adjusting the internal pressure of insulating glass panes is known from US Pat. No. 3,842,567. In this process, either the glass panels are pressed or the glass panels are pulled apart.
- the glass panes are either pressed inwards by means of stamps or pulled apart by suction heads and at the same time ensure that air can flow into or out of the interior of the insulating glass unit.
- the organs that press on the glass panes are equipped with rubber pads and take up only a small fraction of the area of the glass panes, as this is the only way to achieve the desired inward curvature of the glass panes.
- the problem with the known devices is that it takes a long time for the filling process to be completed. It is therefore no longer possible to comply with the cycle times customary for the production of insulating glass (approximately 20 seconds). The reason for this is that the insulating glass unit must be filled slowly with filling gas so that no high pressure builds up in the pane, since otherwise the insulating glass unit would be destroyed, for example because the glass panes detach from the spacer frame.
- the invention has for its object to provide a method of the type mentioned that can be carried out quickly and easily, so that the filling with filling gas does not interfere with the normal cycle times of an insulating glass production line.
- this is achieved by applying the pressure to the glass panes during the filling process by applying plate-shaped pressure elements which essentially cover the entire surface of the glass panes of the insulating glass unit, by measuring the pressure in the gas supply line after the filling process has ended, and by only releases the pressure on the outer surfaces of the glass panes of the insulating glass unit when the pressure determined in this way has reached a preselected value, for example corresponds to the atmospheric pressure.
- the filling gas can be blown into the insulating glass unit at high pressure and thus at a correspondingly high speed, flow speeds of 60 to 200 1 / min are possible. Because the glass panes are pressed against the spacer frame by the external pressure, there is no danger that the glass panes will come loose from the spacer frame. It is also prevented that spacer frames between the two glass panes of the insulating glass unit move outwards under the pressure of the filling gas.
- the method according to the invention prevents the pressure on the outer surfaces of the glass panes of the insulating glass unit from being released too early, since the pressure in the gas supply line is measured after the filling process has ended, and the pressure on the outer surfaces of the glass panes of the insulating glass unit is only released when the so pressure determined a preselected value, e.g. corresponds to the atmospheric pressure.
- a preselected value e.g. corresponds to the atmospheric pressure.
- This also opens up the possibility of building up a preselected pressure in the insulating glass unit in order to prevent the glass sheets of the insulating glass unit from being dented or bulged at different manufacturing and installation locations (lower air pressure at higher installation locations or higher air pressure at lower installation locations). This can be done by adjusting the pressure of the gas inside the insulating glass to a preselected value, the preselected value of the pressure corresponding to the mean air pressure at the installation location of the insulating glass.
- the quantity of filling gas supplied is determined by determining the amount of filling gas supplied per unit of time and that the filling process is stopped when the product of the filling gas quantity per unit time and duration of the filling process corresponds to the volume of the filling gas to be supplied to the interior of the insulating glass unit.
- oxygen sensors are not required in the suction line because the required amount of filling gas is simply blown into the insulating glass unit.
- the two plate-shaped pressure elements that are used in the method according to the invention can be the plates of a press for pressing insulating glass, as is known from DE-A 3 130 645.
- this is only a preferred variant, since it is sufficient in itself if two pressure plates are provided which lie against the outer surfaces of the two glass panes of the insulating glass unit and are pressed against the glass panes with corresponding pressure.
- a pressure sensor can be provided in the line for supplying the filling gas.
- the pressure sensor in the feed line for the filling gas detects the pressure prevailing in the interior of the insulating glass unit and controls the device so that the press is only opened or the pressure on the outer surfaces of the glass panes of the insulating glass unit is released only when a signal from the pressure sensor is given that the gas pressure inside the insulating glass unit, for example corresponds to atmospheric pressure (or a preselected pressure).
- the opening in the spacer frame is closed by injecting a hardening mass, e.g. with the help of a plug made of butyl rubber.
- This mode of operation also makes it possible to adjust the pressure inside the insulating glass pane to the atmospheric pressure normally prevailing at the installation site depending on the altitude of the installation site.
- the openings in the spacer can also be closed in another station.
- the method of operation according to the invention also makes it possible to fill the insulating glass unit with filling gas (e.g. sulfur hexafluoride), which is only partially intended for soundproofing purposes. Until now, this was not possible with an ordinary oxygen sensor in the suction line. In the invention, it is simply sufficient to blow in the predetermined amount of filling gas, based on the volume of the interior of the insulating glass unit (i.e. the desired fraction of the interior volume).
- filling gas e.g. sulfur hexafluoride
- the filling volume i.e. the volume of the interior of the insulating glass unit to be filled (calculated on the basis of the width and height of the insulating glass unit in conjunction with the distance between the two glass panes).
- the required fill gas quantity is determined on the basis of the volume determined. It can then be proceeded in such a way that, based on the flow quantity of filling gas per unit of time measured by the flow measuring device, the filling is stopped after a predetermined period of time, the predetermined period of time corresponding to the volume of filling gas that is to be supplied, based on the flow rate.
- the volume of filling gas to be supplied generally corresponds to 110-120% of the volume of the interior of the insulating glass unit.

Description
Die Erfindung betrifft ein Verfahren zum Füllen einer Isolierglaseinheit mit einem Füllgas, bei dem das Füllgas über mindestens eine Einlaßöffnung in den Innenraum der Isolierglaseinheit eingeführt und über wenigstens eine weitere Öffnung Luft bzw. Luft-Gas-Gemisch aus dem Innenraum der Isolierglaseinheit abgesaugt wird, und bei dem man während des Füllvorganges auf die Außenflächen der Glasscheiben der zu füllenden Isolierglaseinheit einen Druck ausübt, der größer ist als der während des Füllvorganges im Inneren der Isolierglaseinheit herrschende Druck.The invention relates to a method for filling an insulating glass unit with a filling gas, in which the filling gas is introduced into the interior of the insulating glass unit via at least one inlet opening and air or air-gas mixture is sucked out of the interior of the insulating glass unit via at least one additional opening, and in which a pressure is exerted on the outer surfaces of the glass panes of the insulating glass unit to be filled during the filling process, which is greater than the pressure prevailing inside the insulating glass unit during the filling process.
Es sind schon verschiedene Verfahren und Vorrichtungen zum Füllen von Isolierglas mit einem Füllgas vorgeschlagen worden. In diesem Zusammenhang wird auf die EP-A 46 847, die DE-C 3 025 122 sowie die beiden DE-U 8 025 477 und 8 025 478 verwiesen.Various methods and devices for filling insulating glass with a filling gas have already been proposed. In this connection, reference is made to EP-A 46 847, DE-C 3 025 122 and both DE-U 8 025 477 and 8 025 478.
Aus der US-A 3 842 567 ist ein Verfahren zum Einstellen des Innendruckes von Isolierglasscheiben bekannt. Bei diesem Verfahren wird entweder auf die Glastafeln gedrückt oder die Glastafeln werden auseinandergezogen. Hiezu werden bei der US-A 3 842 567 beispielsweise die Glasscheiben mit Hilfe von Stempeln entweder nach innen gedrückt oder durch Saugköpfe auseinandergezogen und gleichzeitig dafür gesorgt, daß Luft in den bzw. aus dem Innenraum der Isolierglaseinheit strömen kann. Die Organe, die auf die Glasscheiben drücken, sind mit Gummipolstern ausgerüstet und nehmen nur einen kleinen Bruchteil der Fläche der Glasscheiben ein, da nur so das angestrebte Nach-Innen-Wölben die Glasscheiben erreichbar ist.A method for adjusting the internal pressure of insulating glass panes is known from US Pat. No. 3,842,567. In this process, either the glass panels are pressed or the glass panels are pulled apart. For this purpose, in US Pat. No. 3,842,567, for example, the glass panes are either pressed inwards by means of stamps or pulled apart by suction heads and at the same time ensure that air can flow into or out of the interior of the insulating glass unit. The organs that press on the glass panes are equipped with rubber pads and take up only a small fraction of the area of the glass panes, as this is the only way to achieve the desired inward curvature of the glass panes.
Die US-A 2 030 869, aus der die Merkmale des einleitenden Teils des Patentanspruchs 1 bekannt sind, beschreibt ein Verfahren zur Herstellung von Isolierglas, bei dem nachgiebige Abstandhalter aus mehreren Lagen verwendet werden. Nach dem Zusammenbau wird die zwischen den Glasscheiben eingeschlossene Luft getrocknet. Dabei werden die Glasscheiben an ihren Rändern mit federnden Klemmen zusammengehalten oder es wird eine einzelne Isolierglaseinheit oder ein Stapel Isolierglasscheiben in eine Presse eingelegt. Die auf die eine oder andere Art und Weise zusammengespannten Isolierglaseinheiten werden in eine Heizkammer gebracht und erwärmt, um den Kleber der Abstandhalter zu aktivieren. Gleichzeitig wird über Sonden in die Isolierglaseinheiten getrocknete Luft eingeleitet und über eine Öffnung im Abstandhalterrahmen Luft aus dem Raum zwischen den Glasscheiben abströmen gelassen, wobei praktisch ohne Überdruck im Inneren der Isolierglaseinheit gearbeitet wird.US-A 2 030 869, from which the features of the introductory part of patent claim 1 are known, describes a method for producing insulating glass in which flexible spacers made of several layers are used. After assembly, the air trapped between the glass panes is dried. The glass panes are held together at their edges with spring clips or a single insulating glass unit or a stack of insulating glass panes is inserted into a press. The insulating glass units clamped together in one way or another are placed in a heating chamber and heated to activate the adhesive of the spacers. At the same time, dried air is introduced into the insulating glass units by means of probes, and air is allowed to flow out of the space between the glass panes via an opening in the spacer frame, work being carried out practically without excess pressure inside the insulating glass unit.
Problematisch bei den bekannten Vorrichtungen ist es, daß es lange Zeit dauert, bis der Füllvorgang beendet ist. Es sind daher die für die Isolierglasherstellung üblichen Taktzeiten (etwa 20 Sekunden) nicht mehr einzuhalten. Grund hiefür ist es, daß das Füllen der Isolierglaseinheit mit Füllgas langsam erfolgen muß, damit sich in der Scheibe kein hoher Druck aufbaut, da sonst die Isolierglaseinheit zerstört würde, beispielsweise weil sich die Glasscheiben vom Abstandhalterrahmen lösen.The problem with the known devices is that it takes a long time for the filling process to be completed. It is therefore no longer possible to comply with the cycle times customary for the production of insulating glass (approximately 20 seconds). The reason for this is that the insulating glass unit must be filled slowly with filling gas so that no high pressure builds up in the pane, since otherwise the insulating glass unit would be destroyed, for example because the glass panes detach from the spacer frame.
Häufig wird beim Füllen von Isolierglaseinheiten mit einem Füllgas das Füllen solange durchgeführt, bis im Bereich der Gasaustrittsstelle der Sauerstoffgehalt des abgeführten Gases einen vorgegebenen Wert unterschreitet. Es ist daher in der Abführleitung ein Sauerstoffsensor vorzusehen, was eine weitere Verteuerung der Anlagen zur Folge hat.When filling insulating glass units with a filling gas, the filling is often carried out until the oxygen content of the discharged gas falls below a predetermined value in the area of the gas outlet point. It is therefore necessary to provide an oxygen sensor in the discharge line, which makes the systems even more expensive.
Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren der eingangs genannten Gattung anzugeben, das rasch und einfach durchgeführt werden kann, so daß das Füllen mit Füllgas die normalen Taktzeiten einer Isolierglasherstellungslinie nicht stört.The invention has for its object to provide a method of the type mentioned that can be carried out quickly and easily, so that the filling with filling gas does not interfere with the normal cycle times of an insulating glass production line.
Erfindungsgemäß wird dies dadurch erreicht, daß man den Druck auf die Glasscheiben während des Füllvorganges durch Anlegen von im wesentlichen die Gesamtfläche der Glasscheiben der Isolierglaseinheit bedeckenden, plattenförmigen Druckelementen aufbringt, daß man nach der Beendigung des Füllvorganges den Druck in der Gaszuführleitung mißt, und daß man den Druck auf die Außenflächen der Glasscheiben der Isolierglaseinheit erst aufhebt, wenn der so ermittelte Druck einem vorgewählten Wert, z.B. dem atmosphärischen Druck, entspricht.According to the invention, this is achieved by applying the pressure to the glass panes during the filling process by applying plate-shaped pressure elements which essentially cover the entire surface of the glass panes of the insulating glass unit, by measuring the pressure in the gas supply line after the filling process has ended, and by only releases the pressure on the outer surfaces of the glass panes of the insulating glass unit when the pressure determined in this way has reached a preselected value, for example corresponds to the atmospheric pressure.
Auf Grund der erfindungsgemäß vorgeschlagenen Maßnahme kann das Füllgas mit hohem Druck und damit mit entsprechend hoher Geschwindigkeit, möglich sind Strömungsgeschwindigkeiten von 60 bis 200 1/min, in die Isolierglaseinheit eingeblasen werden. Dadurch, daß die Glasscheiben durch den von außen angelegten Druck gegen den Abstandhalterrahmen gepreßt werden, besteht keine Gefahr, daß sich die Glasscheiben vom Abstandhalterrahmen lösen. Auch wird verhindert, daß Abstandhalterrahmen zwischen den beiden Glasscheiben der Isolierglaseinheit unter dem Druck des Füllgases nach außen wandern.On the basis of the measure proposed according to the invention, the filling gas can be blown into the insulating glass unit at high pressure and thus at a correspondingly high speed, flow speeds of 60 to 200 1 / min are possible. Because the glass panes are pressed against the spacer frame by the external pressure, there is no danger that the glass panes will come loose from the spacer frame. It is also prevented that spacer frames between the two glass panes of the insulating glass unit move outwards under the pressure of the filling gas.
Mit dem erfindungsgemäßen Verfahren wird verhindert, daß der Druck auf die Außenflächen der Glasscheiben der Isolierglaseinheit zu früh aufgehoben wird, da man nach Beendigung des Füllvorganges den Druck in der Gaszuführleitung mißt, und den Druck auf die Außenflächen der Glasscheiben der Isolierglaseinheit erst aufhebt, wenn der so ermittelte Druck einem vorgewählten Wert, z.B. dem atmosphärischen Druck, entspricht. Dies eröffnet auch die Möglichkeit, in der Isolierglaseinheit einen vorgewählten Druck aufzubauen, um ein Einbuchten oder Ausbeulen der Glastafeln der Isolierglaseinheit bei unterschiedlichem Herstellungs-und Einbauort (geringerer Luftdruck bei höheren Einbauorten bzw. höherer Luftdruck bei tiefer liegenden Einbauorten) zu vermeiden. Hiezu kann so vorgegangen werden, daß man den Druck des Gases im Inneren des Isolierglases auf einen vorgewählten Wert einstellt, wobei der vorgewählte Wert des Druckes dem mittleren Luftdruck am Einbauort des Isolierglases entspricht.The method according to the invention prevents the pressure on the outer surfaces of the glass panes of the insulating glass unit from being released too early, since the pressure in the gas supply line is measured after the filling process has ended, and the pressure on the outer surfaces of the glass panes of the insulating glass unit is only released when the so pressure determined a preselected value, e.g. corresponds to the atmospheric pressure. This also opens up the possibility of building up a preselected pressure in the insulating glass unit in order to prevent the glass sheets of the insulating glass unit from being dented or bulged at different manufacturing and installation locations (lower air pressure at higher installation locations or higher air pressure at lower installation locations). This can be done by adjusting the pressure of the gas inside the insulating glass to a preselected value, the preselected value of the pressure corresponding to the mean air pressure at the installation location of the insulating glass.
Erfindungsgemäß bewährt es sich, wenn man das Volumen des Innenraumes der mit dem Füllgas zu füllenden Isolierglaseinheit ermittelt, daß man die zugeführte Füllgasmenge erfaßt, indem man die Menge des je Zeiteinheit zugeführten Füllgases ermittelt und daß man den Füllvorgang abbricht, wenn das Produkt aus Füllgasmenge je Zeiteinheit und Dauer des Füllvorganges dem dem Innenraum der Isolierglaseinheit zuzuführenden Volumen am Füllgas entspricht. Bei dieser Variante sind Sauerstoffsensoren in der Absaugleitung entbehrlich, da einfach die benötigte Menge an Füllgas in die Isolierglaseinheit eingeblasen wird. Bei dieser erfindungsgemäßen Verfahrensvariante erweist es sich als besonders günstig, daß man mit hohen Gasströmungsgeschwindigkeiten arbeiten kann, so daß eine Vermischung zwischen dem Füllgas und der im Innenraum der Isolierglaseinheit zu verdrängenden Luft weitestgehend vermieden wird.According to the invention, if the volume of the interior of the insulating glass unit to be filled with the filling gas is determined, it proves that the quantity of filling gas supplied is determined by determining the amount of filling gas supplied per unit of time and that the filling process is stopped when the product of the filling gas quantity per unit time and duration of the filling process corresponds to the volume of the filling gas to be supplied to the interior of the insulating glass unit. With this variant, oxygen sensors are not required in the suction line because the required amount of filling gas is simply blown into the insulating glass unit. In this variant of the method according to the invention, it proves to be particularly advantageous that one can work with high gas flow velocities, so that mixing between the filling gas and the air to be displaced in the interior of the insulating glass unit is largely avoided.
Die beiden plattenförmigen Druckelemente, die beim erfindungsgemäßen Verfahren angewendet werden, können die Platten einer Presse zum Verpressen von Isolierglas sein, wie sie aus der DE-A 3 130 645 bekannt ist. Dies ist aber nur eine bevorzugte Variante, da es an sich genügt, wenn zwei Druckplatten vorgesehen sind, welche sich gegen die Außenflächen der beiden Glasscheiben der Isolierglaseinheit anlegen und mit entsprechendem Druck gegen die Glasscheiben gedrückt werden.The two plate-shaped pressure elements that are used in the method according to the invention can be the plates of a press for pressing insulating glass, as is known from DE-A 3 130 645. However, this is only a preferred variant, since it is sufficient in itself if two pressure plates are provided which lie against the outer surfaces of the two glass panes of the insulating glass unit and are pressed against the glass panes with corresponding pressure.
Bei der praktischen Durchführung des Verfahrens der Erfindung kann in der Leitung zum Zuführen des Füllgases ein Drucksensor vorgesehen sein. Der Drucksensor in der Zuführleitung für das Füllgas erfaßt den im Innenraum der Isolierglaseinheit herrschenden Druck und steuert die Vorrichtung so, daß die Presse erst dann geöffnet wird bzw. der Druck auf die Außenflächen der Glasscheiben der Isolierglaseinheit erst dann aufgehoben wird, wenn vom Drucksensor ein Signal abgegeben wird, daß der Gasdruck im Inneren der Isolierglaseinheit z.B. dem atmosphärischen Druck (oder einem vorgewähltem Druck) entspricht. Nach Erreichen des gewünschten Druckes wird die Öffnung im Abstandhalterrahmen durch Einspritzen einer erhärtenden Masse verschlossen, z.B. mit Hilfe eines Pfropfens aus Butylkautschuk. Der gewünschte Druck im Inneren der Isolierglaseinheit kann dadurch erreicht werden, daß nach dem Abschalten der Gaszufuhr die Absaugeinrichtung (Vakuumpumpe) noch weiterläuft, bis der Drucksensor den richtigen Druck (z.B. = atmosphärischer Druck) oder einen anderen entsprechend vorgegebenen Druck anzeigt. Diese Arbeitsweise gestattet es auch, den Druck im Inneren der Isolierglasscheibe auf den am Einbauort in Abhängigkeit von der Seehöhe des Einbauortes normalerweise herrschenden atmosphärischen Druck einzustellen. Um die Taktzeiten zu verkürzen, kann das Verschließen der Öffnungen im Abstandhalter auch in einer weiteren Station erfolgen.When the method of the invention is carried out in practice, a pressure sensor can be provided in the line for supplying the filling gas. The pressure sensor in the feed line for the filling gas detects the pressure prevailing in the interior of the insulating glass unit and controls the device so that the press is only opened or the pressure on the outer surfaces of the glass panes of the insulating glass unit is released only when a signal from the pressure sensor is given that the gas pressure inside the insulating glass unit, for example corresponds to atmospheric pressure (or a preselected pressure). After reaching the desired pressure, the opening in the spacer frame is closed by injecting a hardening mass, e.g. with the help of a plug made of butyl rubber. The desired pressure inside the insulating glass unit can be achieved by continuing to operate the suction device (vacuum pump) after switching off the gas supply until the pressure sensor indicates the correct pressure (e.g. = atmospheric pressure) or another correspondingly specified pressure. This mode of operation also makes it possible to adjust the pressure inside the insulating glass pane to the atmospheric pressure normally prevailing at the installation site depending on the altitude of the installation site. In order to shorten the cycle times, the openings in the spacer can also be closed in another station.
Die erfindungsgemäße Arbeitsweise erlaubt es auch, die für Schallschutzzwecke angestrebte, nur teilweise Füllung der Isolierglaseinheit mit Füllgas (z.B. Schwefelhexafluorid) auszuführen. Dies war bislang mit einem gewöhnlichen Sauerstoffsensor in der Absaugleitung nicht erreichbar. Bei der Erfindung genügt es einfach, die vorgegebene Menge an Füllgas, bezogen auf das Volumen des Innenraums der Isolierglaseinheit (d.h. den gewünschten Bruchteil des Innenraumvolumens), einzublasen.The method of operation according to the invention also makes it possible to fill the insulating glass unit with filling gas (e.g. sulfur hexafluoride), which is only partially intended for soundproofing purposes. Until now, this was not possible with an ordinary oxygen sensor in the suction line. In the invention, it is simply sufficient to blow in the predetermined amount of filling gas, based on the volume of the interior of the insulating glass unit (i.e. the desired fraction of the interior volume).
Beim erfindungsgemäßen Verfahren kann das Füllvolumen, d.h. das Volumen des Innenraums der zu füllenden Isolierglaseinheit (auf Grund der Breite und Höhe der Isolierglaseinheit in Verbindung mit dem Abstand der beiden Glasscheiben berechnet werden). Auf Grund des ermittelten Volumens wird die benötigte Füllgasmenge bestimmt. Es kann dann so vorgegangen werden, daß auf Grund des von der Durchflußmengenmeßeinrichtung gemessenen Strömungsmenge an Füllgas je Zeiteinheit nach einer vorgegebenen Zeitspanne das Füllen abgebrochen wird, wobei die vorgegebene Zeitspanne dem Volumen an Füllgas, das zugeführt werden soll, bezogen auf die Strömungsgeschwindigkeit, entspricht. Das zuzuführende Volumen an Füllgas entspricht in der Regel 110-120% des Volumens des Innenraumes der Isolierglaseinheit.In the method according to the invention, the filling volume, i.e. the volume of the interior of the insulating glass unit to be filled (calculated on the basis of the width and height of the insulating glass unit in conjunction with the distance between the two glass panes). The required fill gas quantity is determined on the basis of the volume determined. It can then be proceeded in such a way that, based on the flow quantity of filling gas per unit of time measured by the flow measuring device, the filling is stopped after a predetermined period of time, the predetermined period of time corresponding to the volume of filling gas that is to be supplied, based on the flow rate. The volume of filling gas to be supplied generally corresponds to 110-120% of the volume of the interior of the insulating glass unit.
Da der Druck, der auf die Außenflächen der Glasscheiben der Isolierglaseinheit ausgeübt wird, größer ist als der im Innenraum während des Füllvorganges aufgebaute Druck, kann gleichzeitig mit dem Füllen der Isolierglaseinheit mit Füllgas ein Planpressen der Isolierglaseinheit ausgeführt werden.Since the pressure which is exerted on the outer surfaces of the glass panes of the insulating glass unit is greater than the pressure built up in the interior during the filling process, a plan pressing of the insulating glass unit can be carried out simultaneously with the filling of the insulating glass unit with filling gas.
