Description

Die Erfindung betrifft eine Vorrichtung zum Verschließen von Spalten zwischen den Enden von vorgefertigten, flexiblen Abstandhaltern, die zwischen den Glastafeln von Isolierglaselementen angeordnet sind, mit einer Düse zum Ausbringen von Versiegelungsmasse, die im Gestell der Vorrichtung beweglich gehaltert istThe invention relates to a device for closing gaps between the ends of prefabricated, flexible spacers, which are arranged between the glass sheets of insulating glass elements, with a nozzle for applying sealing compound, which is movably held in the frame of the device

Bei Verwendung von vorgefertigten endlosen, flexiblen Abstandhaltern, die den Abstand zwischen den Glastafeln von Isolierglaselementen gewährleisten, ergibt sich das Problem die freien Enden des in einem Stück entlang der Ränder der Glastafel aufgebrachten Abstandhalter miteinander dicht zu verbinden.When using prefabricated endless, flexible spacers, which ensure the distance between the glass sheets of insulating glass elements, the problem arises of tightly connecting the free ends of the spacer applied in one piece along the edges of the glass sheet.

In der US-PS 4 561 929 wird hiezu vorgeschlagen, den Spalt zwischen den Enden des Abstandhalters nach dem Verpressen von Isolierglas den Spalt durch Verschmelzen der Enden des Abstandhalters mit einem gewinkelten, beheizbaren Gerät zu verschließen.In US Pat. No. 4,561,929, it is proposed to close the gap between the ends of the spacer after pressing insulating glass, by melting the ends of the spacer with an angled, heatable device.

Ein anderer Vorschlag findet sich in dem DE-GM 87 01 101, in dem vorgeschlagen wird, die beiden Enden des Abstandhalters gleichzeitig mit dem Ausformen einer Ecke im Stoßbereich des Abstandhalters miteinander zu verpressen. Im Gebrauchsmuster G 87 01 101 ist auch der Vorschlag enthalten, Öffnungen in vorgefertigten flexiblen Abstandhaltern (Swiggle-Strip) durch Einbringen eines Pfropfens aus Butylkautschuk zu verschließen. Nähere Einzelheiten, wie dies erfolgen soll, sind dem GM 87 01 101 nicht zu entnehmen.Another proposal can be found in DE-GM 87 01 101, in which it is proposed that the two ends of the spacer be pressed together at the same time as a corner is formed in the joint region of the spacer. Utility model G 87 01 101 also includes the proposal to close openings in prefabricated flexible spacers (swiggle strips) by inserting a plug made of butyl rubber. No further details of how this is to be done can be found in GM 87 01 101.

Eine Zange mit beheizbaren Backen zum Verbinden der Enden eines auf eine Glastafel angesetzten Abstandhalters ist auch in der DE-OS 36 37 561 beschrieben.A pair of pliers with heatable jaws for connecting the ends of a spacer attached to a glass sheet is also described in DE-OS 36 37 561.

Aus der EP-A 103 111 ist es bekannt, aus Hohlprofilleisten bestehende Abstandhalter, die einstückig gebogen sein können, im Bereich der Stoßstelle dadurch zu verbinden, daß in die Hohlprofilleiste an der Stoßstelle eine erhärtende Masse eingespritzt wird. Die in der EP-A 103 111 beschriebene Arbeitsweise soll auch dazu geeignet sein, nicht zu Rahmen gebogene Hohlprofilleisten, die zur Herstellung von Abstandhalterrahmen bestimmt sind, miteinander zu Stücken mit größerer Länge zu verbinden.From EP-A 103 111 it is known to use hollow profile strips to connect existing spacers, which can be bent in one piece, in the area of the joint by injecting a hardening mass into the hollow profile strip at the joint. The method of operation described in EP-A 103 111 should also be suitable for connecting hollow profile strips which are not bent into frames and which are intended for the production of spacer frames, to form pieces of greater length.

Im einzelnen wird in der EP-A 103 111 vorgeschlagen, mit Hilfe einer Kanüle, die eine Schneidkante besitzt, in einer Wand des Abstandhalterprofils eine Öffnung zu erzeugen und dann durch eine gegenüber der Kanüle rückversetzte Düse das Verbindungsmittel (erhärtende Masse) in den Hohlraum einzuspritzen. Während des Einspritzvorganges führt weder die Kanüle noch die Spritzdüse irgendwelche Bewegungen aus. Es sind daher auch keine Antriebe vorgesehen, die geeignet sind die Spritzdüse zu bewegen, während diese zum Einspritzen der Masse in den Abstandhalterrahmen in die in diesem erzeugte Öffnung eingesetzt ist.Specifically, EP-A 103 111 proposes to create an opening in a wall of the spacer profile with the aid of a cannula which has a cutting edge and then to inject the connecting means (hardening mass) into the cavity through a nozzle set back relative to the cannula . Neither the cannula nor the spray nozzle make any movements during the injection process. There are therefore also no drives which are suitable for moving the spray nozzle while it is being used for injecting the mass into the spacer frame into the opening produced therein.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung der eingangs genannten Gattung anzugeben, mit der Spalten zwischen den Enden von zwischen den Glastafeln von Isolierglaselementen angeordneten vorgefertigten, flexiblen Abstandhaltern sicher und dicht verschlossen werden können.The invention has for its object to provide a device of the type mentioned with which gaps between the ends of prefabricated, flexible spacers arranged between the glass sheets of insulating glass elements can be securely and tightly closed.

Erfindungsgemäß wird dies dadurch erreicht, daß die Düse einen Ansatz aufweist, und daß ein Antrieb vorgesehen ist, mit dem der Ansatz der Düse in Richtung der Düsenöffnung in den zu verschließende den Spalt einführbar und während des Ausbringens von Versiegelungsmasse in den Spalt aus diesem herausziehbar ist.According to the invention, this is achieved in that the nozzle has an attachment and in that a drive is provided with which the attachment of the nozzle can be introduced into the gap to be closed in the direction of the nozzle opening and can be pulled out of the gap during the application of sealing compound into the gap .

Da die Düse einen Ansatz aufweist, der in die zu verschließende Öffnung einführbar ist, und die Düse in Richtung ihrer Düsenöffnung beweglich ist, kann die Düse während des Ausbringens von Versiegelungsmasse aus der zu verschließenden Öffnung herausgezogen werden, so daß gewährleistet ist, daß die Öffnung im Abstandhalter über ihre gesamte Tiefe vollständig mit Versiegelungsmasse ausgefüllt wird. So wird ein absolut dichter Verschluß der mit der erfindungsgemäßen Vorrichtung verschlossenen Spalten gewährleistet.Since the nozzle has a projection that can be inserted into the opening to be closed, and the nozzle in the direction its nozzle opening is movable, the nozzle can be pulled out of the opening to be sealed during the application of sealing compound, so that it is ensured that the opening in the spacer is completely filled with sealing compound over its entire depth. This ensures an absolutely tight seal of the gaps closed with the device according to the invention.

Ein weiterer Vorteil der erfindungsgemäßen Vorrichtung ist es, daß sie ohne weiteres in Verbindung mit Vorrichtungen zum Verpressen von Isolierglaselementen und/oder Vorrichtungen zum Füllen von Isolierglaselementen mit Füllgas kombiniert sein kann.Another advantage of the device according to the invention is that it can easily be combined in connection with devices for pressing insulating glass elements and / or devices for filling insulating glass elements with filling gas.

Der Ansatz der Düse kann eine flach rechteckige Form besitzen.The tip of the nozzle can have a flat rectangular shape.

Die Beweglichkeit der Düse in Richtung ihrer Düsenöffnung läßt sich besonders einfach erreichen, wenn die Düse bei einer Vorrichtung mit einem Aufstellrollgang für Isolierglaselemente und einer seitlichen Abstützung für diese an einer Halterung am Rahmen der Vorrichtung um eine im wesentlichen lotrechte Achse verschwenkbar gehaltert ist.The mobility of the nozzle in the direction of its nozzle opening can be achieved particularly easily if the nozzle in a device with a stand-up roller table for insulating glass elements and a lateral support for these is pivotally mounted on a holder on the frame of the device about a substantially vertical axis.

Damit die Düse während des An- und Abtransportes von Isolierglaselementen nicht stört, kann vorgesehen sein, daß die Halterung der Düse quer zur Ebene der Abstützung für die Isolierglaselemente vor- und zurückschiebbar ist. Auf diese Weise kann die Düse während des An- und Abtransportes von Isolierglaselementen aus der Förderebene wegbewegt werden.So that the nozzle does not interfere with the transport of insulating glass elements, it can be provided that the holder of the nozzle can be pushed back and forth transversely to the level of the support for the insulating glass elements. In this way, the nozzle can be moved away from the conveying plane during the transport of insulating glass elements.

In einer Ausführungsform der erfindungsgemäßen Vorrichtung ist vorgesehen, daß als Anschlag zum Positionieren des Isolierglaselementes gegenüber der Düse eine vorzugsweise frei drehbare Rolle vorgesehen ist, die aus einer unter den Rollgang versenkten Lage in eine über diesen angehobene anhebbar ist. Diese frei drehbare Rolle kann als Anschlag zum Positionieren des Isolierglaselementes gegenüber der Düse dienen, wenn sie in eine über den Aufstellrollgang angehobene Stellung angehoben worden ist.In one embodiment of the device according to the invention it is provided that a preferably freely rotatable roller is provided as a stop for positioning the insulating glass element relative to the nozzle, which roller moves from a position sunk under the roller table into a position above it raised can be raised. This freely rotatable roller can serve as a stop for positioning the insulating glass element relative to the nozzle when it has been raised to a position raised above the roll-up roller table.

Weitere Einzelheiten und Merkmale der Erfindung ergeben sich aus den weiteren Unteransprüchen und der nachstehenden Beschreibung des in den Zeichnungen dargestellten Ausführunsbeispiels. Es zeigt:

  • Figur 1 eine Vorrichtung mit einer Düse in Ansicht von vorne,
  • Figur 2 eine Draufsicht zu Figur 1,
  • Figur 3 die Düse im vergrößerten Maßstab und
  • Figur 4 eine in der Vorrichtung vorgesehene anhebbare, frei drehbare Rolle.
Further details and features of the invention emerge from the further subclaims and the following description of the exemplary embodiment illustrated in the drawings. It shows:
  • 1 shows a device with a nozzle in front view,
  • FIG. 2 shows a top view of FIG. 1,
  • Figure 3 shows the nozzle on an enlarged scale
  • Figure 4 is a liftable, freely rotatable roller provided in the device.

Im in den Figuren gezeigten Ausführungsbeispiel ist die erfindungsgemäße Vorrichtung in einem Teil 1 einer Anlage zur Herstellung von Isolierglaselementen vorgesehen, der eine seitliche Abstützung 2 für Isolierglaselemente 5 aufweist. Die seitliche Abstützung ist im gezeigten Ausführungsbeispiel eine mit Rollen 3 bestückte Wand, an deren unterem Rand sich ein Aufstell- und Förderrollgang mit mehreren angetriebenen Förderwalzen 4 befindet. Die Vorrichtung 1 steht über nicht näher gezeigte Füße 6 am Boden auf.In the exemplary embodiment shown in the figures, the device according to the invention is provided in part 1 of a system for producing insulating glass elements, which has a lateral support 2 for insulating glass elements 5. In the exemplary embodiment shown, the lateral support is a wall equipped with rollers 3, on the lower edge of which there is an erecting and conveying roller table with several driven conveyor rollers 4. The device 1 stands on the floor via feet 6 (not shown).

Am in Figur 1 gesehen linken Rand des Anlagenteils 1 befindet sich die erfindungsgemäße Vorrichtung 10 zum Verschließen von Öffnungen in einem nicht gezeigten Abstandhalter des Isolierglaselementes 5. Die Vorrichtung 10 umfaßt eine Düse 11, die über eine Halteplatte 12 an einem Träger 13 befestigt ist. Der Träger 13 ist seinerseits über Stäbe 40 mit dem Gehäuse eines Druckmittelzylinders 14 verbunden. Zusätzlich ist die Halterung 16 des Druckmittelmotors 14 um eine im wesentlichen lotrechte Achse 17 verschwenkbar, wozu das der Düse 11 gegenüberliegende Ende des Druckmittelzylinders 14 mit einem weiteren Druckmittelmotor 18 verbunden ist. Parallel zum Druckmittelmotor 18 ist ein Dämpfungsglied 41 vorgesehen, das die Verschwenkbewegung beim Herausbewegen der Düse 11 bremst. Durch Verschwenken des Druckmittelmotors 14 unter der Wirkung des Druckmittelmotors 18 kann die Düse 11 in Richtung des Doppelpfeiles 12, d.h. etwa in der Förderebene bzw. der Ebene des Isolierglaselementes 5, hin und her bewegt werden.The device 10 according to the invention for closing openings in a spacer (not shown) of the insulating glass element 5 is located on the left edge of the system part 1, as seen in FIG. 1. The device 10 comprises a nozzle 11 which is fastened to a carrier 13 via a holding plate 12. The carrier 13 is in turn connected via rods 40 to the housing of a pressure medium cylinder 14. In addition, the holder 16 of the pressure medium motor 14 can be pivoted about an essentially perpendicular axis 17, for which purpose the end of the pressure medium cylinder 14 opposite the nozzle 11 is connected to a further pressure medium motor 18. In parallel to the pressure medium motor 18, an attenuator 41 is provided, which brakes the pivoting movement when the nozzle 11 is moved out. By pivoting the pressure medium motor 14 under the action of the pressure medium motor 18, the nozzle 11 can in the direction of the double arrow 12, i.e. approximately in the conveying plane or the level of the insulating glass element 5, are moved back and forth.

Der Träger 16 ist zusammen mit dem Lager (Achse 17) in Richtung des Doppelpfeiles 15 im Maschinengestell verschiebbar geführt. Der Antrieb erfolgt z.B. über eine Spindel-Mutter-Anordnung, die unterhalb der Vorrichtung 10 angeordnet ist, und einen Motor. So kann die Düse 11 in Richtung des Doppelpfeiles 15 d.h. quer zur Ebene der Abstützung 2 vor- und zurückbewegt werden.The carrier 16 is guided together with the bearing (axis 17) in the direction of the double arrow 15 in the machine frame. The drive takes place e.g. via a spindle-nut arrangement, which is arranged below the device 10, and a motor. So the nozzle 11 in the direction of the double arrow 15 i.e. be moved back and forth across the plane of the support 2.

Der Druckmittelmotor 14 beaufschlagt einen ggf. beheizten Vorratszylinder 20 für Dichtmittel. Am vorderen Ende des Vorratszylinders 20 ist ein Absperrorgan vorgesehen, das von einem Druckmittelmotor 42 über einen Hebel 43 geöffnet und geschlossen werden kann. Sobald das Absperrorgan geöffnet ist, wird ein Dosierkolben 44 von einem Druck mittelmotor 45 nach unten geschoben und das Dichtmittel strömt aus der Düse 11, während sie aus der Öffnung des Abstandhalters herausbewegt wird.The pressure medium motor 14 acts on a possibly heated storage cylinder 20 for sealant. At the front end of the storage cylinder 20, a shut-off device is provided which can be opened and closed by a pressure medium motor 42 via a lever 43. As soon as the shut-off device is open, a metering piston 44 is depressurized middle motor 45 pushed down and the sealant flows out of the nozzle 11 as it is moved out of the opening of the spacer.

Wie aus Fig. 3 erkennbar, ist die Düse 11 mit einem Ansatz 21 ausgestattet, der in die zu verschließende Öffnung im Abstandhalter einführbar ist. Da es sich bei den zu verschließenden Öffnungen in der Regel um den Spalt zwischen den Enden eines vorgefertigten, flexiblen, zwischen den Glastafeln von Isolierglaselementen 5 angeordneten Abstandhalters handelt, hat der Ansatz 21 für gewöhnlich eine flach rechteckartige Form.As can be seen from Fig. 3, the nozzle 11 is equipped with an extension 21 which can be inserted into the opening to be closed in the spacer. Since the openings to be closed are usually the gap between the ends of a prefabricated, flexible spacer arranged between the glass panels of insulating glass elements 5, the projection 21 usually has a flat, rectangular shape.

Wie in den Figuren 1 und 2 gezeigt, ist im Bereich der Vorrichtung 10 eine Anordnung 30 mit einer frei drehbaren Rolle 31 vorgesehen, die unter der Einwirkung eines Druckmittelzylinders 32 aus einer unter die Rollen 4 des Aufstell- und Förderrollganges versenkten Lage (Figur 1) in eine gegenüber diesem angehobene Lage anhebbar ist. Hiezu ist die frei drehbare Rolle 31 an einem Träger 33 montiert, der in einer an dem Anlagenteil 1 befestigten Führung 34 geführt ist. Mit dem unteren Teil des Trägers 33 ist die Kolbenstange 35 des Druckmittelzylinders 32 verbunden.As shown in FIGS. 1 and 2, an arrangement 30 with a freely rotatable roller 31 is provided in the area of the device 10. can be raised in a raised position relative to this. For this purpose, the freely rotatable roller 31 is mounted on a carrier 33 which is guided in a guide 34 fastened to the system part 1. The piston rod 35 of the pressure medium cylinder 32 is connected to the lower part of the carrier 33.

Die anhebbare, frei drehbare Rolle 31 dient dazu, das Isolierglaselement, in dessen Abstandhalter eine zu verschließende Öffnung vorgesehen ist, gegenüber der Düse 11 richtig auszurichten. Hiezu wird das Isolierglaselement auf dem Rollengang 4 so weit gefördert, daß seine in Förderrichtung gesehen hintere vertikale Kante nach der anhebbaren Rolle 31 angeordnet ist. Nach dem Anheben der Rolle 31 wird das Isolierglaselement 5 auf dem Rollengang zurück gefördert, bis es an der Rolle 31 anliegt.The liftable, freely rotatable roller 31 is used to correctly align the insulating glass element, in the spacer of which there is an opening to be closed, with respect to the nozzle 11. For this purpose, the insulating glass element is conveyed on the roller conveyor 4 to such an extent that its rear vertical edge, viewed in the conveying direction, is arranged after the roller 31 which can be raised. After lifting the roller 31, the insulating glass element 5 is conveyed back on the roller conveyor until it rests on the roller 31.

Die soeben beschriebene Vorrichtung arbeitet wie folgt:The device just described works as follows:

Ein Isolierglaselement, bei dem der Spalt zwischen dem Ende eines zwischen ihnen angeordneten Abstandhalters (swiggle strip) noch nicht verschlossen worden ist, wird in die in Fig. 1 gezeigte Lage in den Anlageteil 1 gefördert. Wenn zum Ausbilden der in Fig. 1 linken unteren Ecke im Abstandhalter des Isolierglaselementes unter Verwendung einer Vorrichtung gemäß dem DE- GM 87 01 101 ausgebildet worden ist, dann befindet sich der Spalt zwischen den beiden Enden des Abstandhalters in einer genau definierten Höhenlage. In dieser Höhe, d.h. dem Spalt gegenüberliegend ausgerichtet, ist der Ansatz 21 der Düse 11 angeordnet. Nachdem das Isolierglaselement 5, wie oben beschrieben, mit Hilfe der Rolle 31 richtig positioniert und die Vorrichtung 10 und damit die Düse 11 durch die Spindel-Mutter-Anordnung vorgeschoben worden ist, wird durch Betätigen des Druckmittelzylinders 18 die Düse 11 bzw. ihr Ansatz 21 in den Spalt zwischen den Enden des Abstandhalters eingeführt und die Förderung von Versiegelungsmasse in Gang gesetzt. Während des Auspressens von Versiegelungsmasse aus der Düsenöffnung unter der Wirkung des Dosierkolbens 44 wird die Düse 11 und somit aus ihr Ansatz 21 nach und nach aus dem Spalt herausgezogen, wozu wiederum der Druckmittelzylinder 18 betätigt wird.An insulating glass element in which the gap between the End of a spacer (swiggle strip) arranged between them has not yet been closed, is conveyed into the position shown in FIG. 1 in the system part 1. If in order to form the lower left corner in FIG. 1 in the spacer of the insulating glass element using a device according to DE-GM 87 01 101, then the gap between the two ends of the spacer is at a precisely defined height. At this height, ie aligned opposite the gap, the extension 21 of the nozzle 11 is arranged. After the insulating glass element 5, as described above, has been correctly positioned with the aid of the roller 31 and the device 10 and thus the nozzle 11 have been advanced through the spindle-nut arrangement, the nozzle 11 or its attachment 21 is actuated by actuating the pressure medium cylinder 18 inserted into the gap between the ends of the spacer and the delivery of sealant started. During the pressing out of sealing compound from the nozzle opening under the action of the metering piston 44, the nozzle 11 and thus its attachment 21 are gradually pulled out of the gap, for which purpose the pressure medium cylinder 18 is actuated again.

Nachdem der Ansatz 21 zur Gänze aus dem Spalt, d.h. der zu verschließenden Öffnung im Abstandhalter, herausgezogen worden ist, wird die Zufuhr von Versiegelungsmasse durch Schließen des vom Hebel 43 betätigten Absperrorgans abgestoppt und die Düse 11 wieder in ihre hinter der Förderebene der Isolierglaselemente 5 angeordnete Bereitschaftsstellung zurückgezogen.After the approach 21 is completely out of the gap, i.e. of the opening to be closed in the spacer has been pulled out, the supply of sealing compound is stopped by closing the shut-off element actuated by the lever 43 and the nozzle 11 is pulled back into its ready position arranged behind the conveying plane of the insulating glass elements 5.
