Abstract

The method involves a thermoplastics distance holder (2) being sprayed into an insulating glass pane (1) at least at one point where a cavity (4) is formed. The cavity is formed by area-wise deformation of the distance holder in the direction of the glass pane. In this way, the distance holder in the area of the cavity is so deformed that with the packet comprising the glass pane and the distance holder being pressed together an insulating glass pane is formed.

Description

Die Erfindung betrifft ein Verfahren zum Zusammenbauen und Verpressen von Isolierglas mit den Mermalen des einleitenden Teils des unabhänigen Anspruches.The invention relates to a method for assembling and pressing of insulating glass with the characteristics of the introductory part of the independent claim.

Neben Isolierglas, bei dem die wenigstens zwei Glasscheiben durch einen beidseitig mit Dicht- und Klebemittel (z.B. einem Butylkautschuk) belegten, metallischen, meist als Hohlprofil ausgebildeten Abstandhalter mit Abstand voneinander verbunden sind, ist auch Isolierglas bekannt, bei dem zwischen den Glasscheiben des Isolierglases ein Strang aus thermoplastischem Kunststoff als Abstandhalter vorgesehen ist.In addition to insulating glass, in which the at least two panes of glass one on both sides with sealant and adhesive (e.g. a butyl rubber) coated, metallic, usually designed as a hollow profile Spacers are connected at a distance from each other is also Insulating glass is known in which between the glass panes of the insulating glass a strand of thermoplastic plastic as a spacer is provided.

Beim Verpressen von Isolierglas mit einem thermoplastischen Abstandhalter ergeben sich insoferne Probleme, als der thermoplastische Abstandhalter beim Pressen von Isolierglas in einer Richtung quer zur Ebene des Isolierglases gestaucht wird, so daß, wenn nicht besondere Maßnahmen getroffen werden, im Innenraum des Isolierglases Überdruck entsteht, der zur Folge hat, daß die Glasscheiben mehr oder weniger stark nach außen gewölbt, also konvex, sind. Dies gilt auch für Isolierglas, bei dem der Scheibenzwischenraum zur Verbesserung der thermischen Isoliereigenschaften, und zur Verbesserung des Schallschutzes mit einem anderen Gas als Luft, z.B. mit einem Edelgas, gefüllt ist.When pressing insulating glass with a thermoplastic spacer Problems arise insofar as the thermoplastic Spacer when pressing insulating glass in one direction is compressed transversely to the level of the insulating glass, so that if not special measures are taken in the interior of the insulating glass Overpressure arises, which has the consequence that the glass panes more or less curved outwards, i.e. convex. this applies also for insulating glass, in which the space between the panes improves the thermal insulation properties, and for improvement soundproofing with a gas other than air, e.g. with a Noble gas, is filled.

Es ist schon vorgeschlagen worden, in dem auf die eine Glasscheibe aufgespritzten, thermoplastischen Abstandhalter in seiner der zweiten Glasscheibe zugekehrten Seite wenigstens eine Kerbe vorzusehen, mit dem Ziel, beim Pressen des Isolierglases einen Druckausgleich zu erlauben. Solche Kerben in der einen Seite des Abstandhalters ergeben aber eine Druckausgleichsöffnung mit einer nur geringen Querschnittsfläche, so daß der Druckausgleich bei den angestrebten, kurzen Taktzeiten unvollständig ist, und im gepreßten Isolierglas Überdruck bestehen bleibt (EP 805 254 A).It has already been suggested in which on the one pane of glass sprayed, thermoplastic spacer in its the second To provide at least one notch on the side facing the glass pane, with the aim of balancing the pressure when pressing the insulating glass allow. Such notches result in one side of the spacer but a pressure compensation opening with only a small cross-sectional area, so that the pressure equalization at the desired short cycle times is incomplete, and in the pressed insulating glass Overpressure remains (EP 805 254 A).

Ein Verfahren der eingangs genannten Gattung ist aus der EP 805 254 A bekannt. Nachteilig bei dem aus der EP 805 254 A bekannten Verfahren ist es, daß im Bereich der Vertiefungen, die durch Verringern der Breite des Abstandhalters schon beim Aufspritzen desselben auf die Glasscheibe erzeugt werden sollen, schlußendlich "Material", nämlich thermoplastischer Kunststoff, fehlt.A method of the type mentioned at the outset is known from EP 805 254 A known. A disadvantage of the method known from EP 805 254 A it is that in the area of the depressions caused by diminishing the width of the spacer when it is sprayed on the glass pane is to be produced, ultimately "material", namely thermoplastic, is missing.

Der Erfindung liegt die Aufgabe zu Grunde, ein Verfahren der eingangs genannten Gattung anzugeben, mit dem der Druckausgleich beim Pressen von Isolierglas mit einem thermoplastischen Abstandhalter vollständig oder nahezu vollständig möglich ist.The invention is based on the object of a method of the beginning Specify the type with which the pressure equalization at Pressing insulating glass with a thermoplastic spacer is completely or almost completely possible.

Gelöst wird diese Aufgabe gemäß der Erfindung mit einem Verfahren, das sich durch die kennzeichnenden Mermale des unabhängigen Anspruches auszeichnet.This object is achieved according to the invention with a method that is characterized by the characteristic features of the independent claim distinguished.

Bevorzugte und vorteilhafte Ausgestaltungen des erfindungsgemäßen Verfahrens sind Gegenstand der Unteransprüche.Preferred and advantageous embodiments of the invention Procedures are the subject of the subclaims.

Dadurch, daß bei dem erfindungsgemäßen Verfahren in dem auf die eine Glasscheibe aufgespritzten Abstandhalter in seiner der zweiten Glasscheibe zugekehrten Seite durch bereichsweises Verformen des Abstandhalters eine flache Vertiefung erzeugt wird, ergibt sich nach dem Ansetzen der zweiten Glasscheibe auf den Abstandhalter eine hinreichend große, schlitzförmige Öffnung, durch die beim Pressen des Isolierglases Druckausgleich in hinreichendem Ausmaß möglich ist.The fact that in the method according to the invention in one Glass of sprayed spacer in its the second Side facing glass pane by deforming the Spacer a shallow depression is produced, follows attaching the second pane of glass to the spacer sufficiently large, slit-shaped opening, through which during pressing of the insulating glass pressure compensation to a sufficient extent possible is.

Vorteilhaft bei dem Verfahren der Erfindung ist, daß auch in dem Bereich der erfindungsgemäß hergestellten Vertiefung genauso viel Werkstoff vorhanden wie in den übrigen Bereichen des thermoplastischen Abstandhalters, da beim erfindungsgemäßen Verfahren zunächst ein Abstandhalter mit über seine gesamte Länge gleichmäßiger Querschnittsform (also noch ohne Vertiefung) aufgespritzt wird. Erst dann wird an der wenigstens einen Stelle, an der dies notwendig und für einen hinreichenden Druckausgleich förderlich ist, durch Verformen des thermoplastischen Abstandhalters eine Vertiefung hergestellt. Dabei ergibt sich auch im Bereich der Vertiefung eine Querschnittsform des Abstandhalters, die der Querschnittsform des Abstandhalters von verpreßtem Isolierglas auch außerhalb des Bereiches der ursprünglich vorhanden Vertiefungen entspricht. Es fehlt also beim erfindungsgemäßen Verfahren an keiner Stelle an "Material", so daß eine Isolierglasscheibe erzielt wird, die ringsum gleichmäßige Eigenschaften besitzt und insbesondere ringsum gleichmäßig gas- und feuchtigkeitsdicht ist.It is advantageous in the method of the invention that also in the Just as much area of the depression produced according to the invention Material available as in the other areas of thermoplastic Spacer, since initially in the method according to the invention a spacer with a uniform cross-sectional shape over its entire length (i.e. still without recess) is sprayed on. First then at the at least one point where this is necessary and is conducive to adequate pressure compensation by deforming a recess is made of the thermoplastic spacer. This also results in a cross-sectional shape in the area of the depression of the spacer, which is the cross-sectional shape of the spacer of pressed insulating glass also outside the area corresponds to the original wells. So it is missing at no point in the method according to the invention at "material", so that an insulating glass pane is obtained which is uniform all around Has properties and especially gas and gas all around is moisture proof.

Bevorzugt ist im Rahmen der Erfindung, wenn die Vertiefung durch bereichsweises Zusammendrücken des auf die eine Glasscheibe aufgespritzten Abstandhalters quer zur Ebene der Glasscheibe erzeugt wird. Dabei ist es bevorzugt, wenn an beiden Enden der Vertiefung ein fließender Übergang ohne scharfe Kanten zu der der zweiten, an den Abstandhalter anzusetzenden Glasscheibe zugekehrten Seite des Abstandhalters vorliegt.It is preferred within the scope of the invention if the depression is through area-by-area compression of the sprayed onto a glass pane Spacer generated across the plane of the glass sheet becomes. It is preferred if at both ends of the recess a smooth transition without sharp edges to that of the second the spacer glass pane facing side of the Spacer is present.

Beim erfindungsgemäßen Verfahren kann man so vorgehen, daß man den Abstandhalter im Bereich der in ihm zu erzeugenden Vertiefung so weit zusammendrückt, daß die der zweiten Glasscheibe zugekehrte Fläche der Vertiefung von der Glasscheibe, auf die der Abstandhalter aufgespritzt ist, einen Abstand hat, welcher der quer zur Ebene des Isolierglases gemessenen Höhe des Abstandhalters nach dem Verpressen des Isolierglases entspricht.In the method according to the invention you can proceed so that the Spacers in the area of the depression to be created in it squeezed wide enough to face the second pane of glass Surface of the recess from the glass pane on which the spacer is sprayed on, has a distance which is transverse to the plane of the Insulating glass measured height of the spacer after pressing of the insulating glass.

Weitere Einzelheiten, Vorteile und Merkmale des erfindungsgemäßen Verfahrens ergeben sich aus der nachstehenden Beschreibung eines Beispieles der Erfindung, in der auf die angeschlossene Zeichnung Bezug genommen wird. Es zeigt

    • Further details, advantages and features of the method according to the invention result from the following description of an example of the invention, in which reference is made to the attached drawing. It shows
  • 1 is a thermoplastic spacer sprayed onto a glass pane with a recess,
  • 2 shows a section along the line II-II in FIG. 1,
  • Fig. 3 is a plan view of the spacer in the region of the recess and

    • Auf eine Glasscheibe 1 wird nach einem an sich beliebigen Verfahren aus einer Düse ein thermoplastischer Abstandhalter 2 beispielsweise mit im wesentlichen rechteckiger Querschnittsform aufgespritzt. Auf die freie Fläche, also die von der (ersten) Glasscheibe 1 abgekehrte Fläche 3 des Abstandhalters 2 wird beim Zusammenbauen des Isolierglases eine zweite Glasscheibe 8 aufgesetzt. Beim Verpressen des so zusammengestellten Scheibenpaketes aus den beiden Glasscheiben 1 und 8 und dem dazwischen angeordneten Abstandhalter 2 wird dieser so weit zusammengedrückt, daß seine Fläche 3 dann die in Fig. 1 und 4 durch die strichlierte Linie 7 angedeutete Lage einnimmt. Ein Zwischenstadium des Verpressens des Scheibenpaketes ist in Fig. 4 wiedergegeben.A glass pane 1 is made by any method per se for example, a thermoplastic spacer 2 from a nozzle sprayed with a substantially rectangular cross-sectional shape. On the free area, that is to say that facing away from the (first) glass pane 1 Surface 3 of the spacer 2 is when assembling the insulating glass a second glass pane 8 is placed. When pressing this way Compiled pane package from the two glass panes 1 and 8 and the spacer 2 arranged therebetween is so widely compressed that its surface 3 then that in FIGS. 1 and 4 occupies by the dashed line 7 indicated position. An intermediate stage the pressing of the disk package is in FIG. 4 reproduced.

    Wie Fig. 1 zeigt, ist in der Fläche 3 des thermoplastischen Abstandhalters 2 eine Vertiefung 4 vorgesehen, deren freie, von der Glasscheibe 1 weg weisende Fläche 5 von der Glasscheibe 1, auf die der Abstandhalter 2 aufgespritzt worden ist, einen kleineren Abstand aufweist, als die übrige freie Fläche 3 des Abstandhalters 2. Die Übergänge 6 zwischen der Fläche 5 im Bereich der Vertiefung 4 zur Fläche 3 des Abstandhalters 2 sind, wie in Fig. 1 gezeigt, ohne scharfe Kanten, also fließend ausgebildet.1 shows, in the surface 3 of the thermoplastic spacer 2 a recess 4 is provided, the free of which Glass plate 1 facing surface 5 of the glass plate 1, on the the spacer 2 has been sprayed on, a smaller distance has, as the remaining free surface 3 of the spacer 2. Die Transitions 6 between the surface 5 in the area of the recess 4 Surface 3 of the spacer 2 are, as shown in Fig. 1, without sharp edges, so flowing.

    Die Vertiefung 4 kann dadurch erzeugt werden, daß der Abstandhalter 2 im Bereich der Vertiefung 4 in Richtung auf die Glasscheibe 1 hin verformt wird. Dies kann dadurch erfolgen, daß auf den Abstandhaltaer 2 gedrückt wird, wozu beispielsweise ein Druckstempel verwendet wird, der eine der gewünschten Form der Vertiefung 4 einschließlich der Übergänge 6 entsprechende, auf den Abstandhalter 2 einwirkende Druckfläche aufweist. Der Druckstempel kann im Bereich seiner Druckfläche erwärmt sein.The recess 4 can be produced in that the spacer 2 in the area of the recess 4 in the direction of the glass pane 1 is deformed. This can be done in that the spacer 2 is pressed, for which purpose, for example, a pressure stamp is used is one of the desired shape of the recess 4 including of the transitions 6 corresponding to the spacer 2 has acting pressure area. The pressure stamp can be in the area its printing surface must be heated.

    Wie in Fig. 2 schematisch und idealisiert dargestellt, besitzt der Abstandhalter 2 im Bereich der Vertiefung 4 eine schienenkopf ähnliche Querschnittsform mit seitlichen Ausbauchungen 9.As shown schematically and idealized in Fig. 2, the Spacer 2 in the region of the recess 4 a rail head similar Cross-sectional shape with lateral bulges 9.

    Fig. 3 zeigt den Abstandhalter 2 im Bereich der Vertiefung 4 und die durch das bereichsweise Verformen des Abstandhalters 2 entstandenen, seitlichen Ausbauchungen 9 in Draufsicht. Es ist darauf hinzuweisen, daß der besseren Verständlichkeit wegen das Ausmaß der seitlichen Ausbauchungen 9 und deren Form übertrieben und idealisiert dargestellt ist. Fig. 3 shows the spacer 2 in the region of the recess 4 and the caused by the deformation of the spacer 2 in some areas, lateral bulges 9 in plan view. It should be noted that for better understanding because of the extent of the lateral Bulges 9 and their shape exaggerated and idealized is.

    Aus Fig. 4 ist ersichtlich, daß beim Verpressen des Scheibenpaketes aus den Glasscheiben 1 und 8 und dem zwischen diesem angeordneten, thermoplastischen Abstandhalter 2 auch bei fortgeschrittenem Verpreßvorgang, wenn also die Glasscheiben 1 und 8 einander unter Zusammendrücken des Abstandhalters 2 bereits angenähert worden sind, im Bereich der Vertiefung 4 des Abstandhalters 2 noch genügend Querschnittsfläche für einen wirksamen Druckausgleich bleibt. Erst am Ende des Preßvorganges, wenn die Seite der Glasscheibe 8, die der anderen Glasscheibe 1, auf die der Abstandhalter 2 aufgespritzt worden ist, zugekehrt ist, die durch die Linie 7 symbolisierte Endlage erreicht hat, liegt die Glasscheibe 8 auch im Bereich der vorher im Abstandhalter 2 vorhandenen Vertiefung 4 am Abstandhalter 2 an. Der Abstandhalter 2 hat dann über seine gesamte Länge im wesentlichen eine Querschnittsform, die in Fig. 2 für den Bereich der Vertiefung 4 dargestellt ist.From Fig. 4 it can be seen that when pressing the disc package from the glass panes 1 and 8 and the one arranged between them, thermoplastic spacer 2 even with advanced pressing, so if the glass panes 1 and 8 under each other Compressing the spacer 2 have already been approximated, sufficient in the area of the recess 4 of the spacer 2 Cross-sectional area remains for effective pressure equalization. First at the end of the pressing process, if the side of the glass sheet 8, the another glass pane 1 onto which the spacer 2 is sprayed has been turned, symbolized by line 7 Has reached the end position, the glass pane 8 is also in the region of previously existing recess 4 in the spacer 2 on the spacer 2 on. The spacer 2 then has in its entire length essentially a cross-sectional shape shown in Fig. 2 for the area the recess 4 is shown.

    Insbesondere bei großformatigem Isolierglas kann im Abstandhalter 2 auch mehr als eine Vertiefung 4 hergestellt werden. Die Vertiefung 4 oder die Vertiefungen 4 können in jedem Fall beispielsweise eine Länge von etwa 3 cm haben. Sinngemäß kann das erfindungsgemäße Verfahren auch bei Isolierglas an mehr als zwei Glasscheiben angewendet werden.In the case of large-format insulating glass in particular, the spacer 2 more than one depression 4 can also be produced. The deepening 4 or the recesses 4 can in any case, for example Have a length of about 3 cm. Analogously, the invention Process also used for insulating glass on more than two glass panes become.

    Zusammenfassend kann ein bevorzugtes Ausführungsbeispiel der Erfindung wie folgt beschrieben werden:In summary, a preferred embodiment of the invention can be described as follows:

    Um beim Verpressen von Isolierglas mit einem thermoplastischen Abstandhalter 2 Druckausgleich zu erlauben, damit im Inneren des gepreßten Isolierglases Überdruck vermieden wird, wird an wenigstens einer Stelle des thermoplastischen Abstandhalters 2, der auf eine 1 der Glasscheiben 1, 8 aufgespritzt ist, eine flache Vertiefung 4 vorgesehen. Die flache Vertiefung 4 wird durch bereichsweises Verformen des Abstandhalters 2 in Richtung auf die Glasscheibe 1, auf die der Abstandhalter aufgespritzt worden ist, hin erzeugt. Dabei wird der Abstandhalter 2 im Bereich der Vertiefung 4 soweit verformt, wie der Abstandhalter 2 beim Verpressen des Paketes aus Glasscheiben und Abstandhalter zu einer Isolierglasscheibe verformt wird. Die freie, der zweiten Glasscheibe 8 zugekehrte Fläche 5 im Bereich der Vertiefung 4 hat von der Glasscheibe 1, auf die der Abstandhalter 2 aufgespritzt ist, bevorzugt einen Abstand, der dem Abstand der beiden Glasscheiben 1, 8 im fertiggepreßten Isolierglas entspricht. Von Vorteil ist dabei, daß im Ergebnis - anders als bei Kerben im Abstandhalter - eine Isolierglasscheibe erhalten wird, deren Abstandhalter über seine ganze Länge die gleichen Eigenschaften und Abmessungen hat.To when insulating glass is pressed with a thermoplastic Spacers 2 to allow pressure equalization, so inside the pressed insulating glass overpressure is avoided at least a location of the thermoplastic spacer 2, which is on a 1st the glass panes 1, 8 are sprayed on, a shallow depression 4 intended. The shallow depression 4 is formed by deforming it in areas of the spacer 2 in the direction of the glass sheet 1 the spacer has been sprayed on. Here the spacer 2 is deformed in the area of the recess 4, like the spacer 2 when pressing the package out Glass panes and spacers deformed into an insulating glass pane becomes. The free surface 5 facing the second glass pane 8 in Area of the recess 4 has from the glass sheet 1 to which the Spacer 2 is sprayed on, preferably a distance that the Distance between the two glass panes 1, 8 in the pressed insulating glass corresponds. The advantage here is that the result - unlike in Notches in the spacer - an insulating glass pane is obtained whose spacers have the same properties over their entire length and dimensions.
