Abstract

A sealing nozzle (4) is movable along an edging gap in a pane of insulating glass (51), and turned round an axis at right angles to the plane of the insulating glass pane. The distance between the sealing nozzle and the axis during the sealing process can be altered. The sealing nozzle is movable away from the axis under spring pressure. Sensors measure the pressure of the sealing nozzle against the edge of the pane. A control increases and diminishes the distance between axis and sealing nozzle with rising and decreasing pressure. A meter (22) for the depth of the edge gap is positioned in front of the sealing nozzle in the direction of travel.

Description

Die Erfindung betrifft ein Verfahren mit den Merkmalen der Oberbegriffe der Patentansprüche 1 und 3.The invention relates to a method with the features of Preambles of claims 1 and 3.

Beim Füllen der Randfugen von Isolierglasscheiben mit Versiegelungsmasse sind besonders die Ecken der Isolierglasscheiben problematisch, da die Versiegelungsdüse, wenn sie an eine Ecke kommt, üblicherweise über diese hinaus fährt, wobei der Austritt von Versiegelungsmasse aus der Versiegelungsdüse unterbrochen werden muß. Die Versiegelungsdüse wird anschließend um eine senkrecht zur Ebene der Isolierglasscheibe stehende Achse verschwenkt (bei rechteckigen Scheiben um 90°) und anschließend wieder an den Rand der Isolierglasscheibe im Bereich der Ecke angesetzt, worauf das Zuführen von Versiegelungsmasse wieder aufgenommen und die Versiegelungsdüse entlang des Randes der Isolierglasscheibe weiterbewegt wird. Dabei ergeben sich zum einen Probleme mit der exakten Dosierung von Versiegelungsmasse sowohl beim Beenden als auch beim Wiederaufnehmen des Versiegelns, so dass im Eckbereich in die Randfuge der Isolierglasscheibe häufig entweder zu viel oder zu wenig Versiegelungsmasse eingebracht wird. Des weiteren ist es nachteilig, wenn die Zufuhr von Versiegelungsmasse unterbrochen wird, da dies im Eckbereich zu undichten Stellen oder Fehlern in der Versiegelung führen kann.When filling the edge joints of insulating glass panes with sealing compound are especially the corners of the insulating glass panes problematic because the sealing nozzle when it is on a corner comes, usually goes beyond this, with the exit interrupted by sealing compound from the sealing nozzle must become. The sealing nozzle is then turned around an axis perpendicular to the plane of the insulating glass pane swiveled (by 90 ° for rectangular panes) and then back to the edge of the insulating glass pane in the area of Set corner, whereupon the supply of sealant resumed and the sealing nozzle along the edge the insulating glass pane is moved on. Surrender on the one hand there are problems with the exact dosing of sealing compound both when quitting and when resuming sealing, so that in the corner area in the edge joint of the Insulating glass panes often either too much or too little Sealing compound is introduced. Furthermore, it is disadvantageous when the supply of sealant is interrupted will cause leaks or defects in the corner area can result in the seal.

Aus der DE 28 16 437 B ist ein Verfahren zum Versiegeln einer Isolierglasscheibe bekannt, bei dem Versiegelungsmasse aus einer relativ zu der Isolierglasscheibe bewegten Versiegelungsdüse in die Randfuge der Isolierglasscheibe eingespritzt wird, wobei während des Herumbewegens der Versiegelungsdüse um eine Ecke der Isolierglasscheibe und Verdrehens der Versiegelungsdüse um eine zur Ebene der Isolierglasscheibe senkrechte Achse kontinuierlich Versiegelungsmasse in die Randfuge der Isolierglasscheibe eingespritzt wird. Die Achse, um welche die Versiegelungsdüse verdrehbar ist, wird im Bereich einer Ecke der Isolierglasscheibe entlang einer Bahn bewegt, die von der Außenkontur der Isolierglasscheibe abweicht, insbesondere außerhalb der Isolierglasscheibe verläuft, wobei die Bahn der Achse stets den gleichen Abstand von der Außenkontur der Isolierglasscheibe hat.DE 28 16 437 B describes a method for sealing a Insulating glass pane known from the sealing compound a sealing nozzle moved relative to the insulating glass pane injected into the edge joint of the insulating glass pane being, while moving the sealing nozzle around a corner of the insulating glass pane and twisting the sealing nozzle around a perpendicular to the level of the insulating glass pane Continuous sealing compound in the edge joint of the axis Insulating glass pane is injected. The axis around which the Sealing nozzle can be rotated in the area of a corner the insulating glass pane moves along a path that is moved by the The outer contour of the insulating glass pane deviates, in particular runs outside the insulating glass pane, the path of the Axis always the same distance from the outer contour of the insulating glass pane Has.

Die DE 28 34 902 A zeigt eine Vorrichtung mit einer Versiegelungsdüse, die entlang einer Randfuge einer Isolierglasscheibe bewegbar und um eine im rechten Winkel zur Ebene der Isolierglasscheibe ausgerichtete Achse verdrehbar ist, wobei der Abstand zwischen Versiegelungdüse und Achse während des Versiegelungsvorganges veränderbar ist, insbesondere ist die Versiegelungsdüse gegen die Kraft einer Feder von der Achse weg bewegbar.
Für das Versiegeln von Isolierglasscheiben, bei dem Versiegelungsmasse in die Randfuge der Isolierglasscheibe eingespritzt wird, sind Düsen bekannt, die in die Randfuge eintauchen (vgl. DE 28 34 902 A). Bekannt sind auch sogenannte "ballige" Düsen, die am Rand der Glasscheiben von Isolierglasscheiben aufsitzend bewegt werden (vgl. DE 41 36 653 A und EP 0 857 849 A).DE 28 34 902 A shows a device with a sealing nozzle which can be moved along an edge joint of an insulating glass pane and rotated about an axis oriented at right angles to the plane of the insulating glass pane, the distance between the sealing nozzle and the axis being changeable during the sealing process, in particular being variable the sealing nozzle can be moved away from the axis against the force of a spring.
For the sealing of insulating glass panes, in which sealing compound is injected into the edge joint of the insulating glass pane, nozzles are known which dip into the edge joint (cf. DE 28 34 902 A). So-called "spherical" nozzles are also known, which are moved by insulating glass panes sitting on the edge of the glass panes (cf. DE 41 36 653 A and EP 0 857 849 A).

Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren anzugeben, mit welchen die oben geschilderten Nachteile vermieden werden können.The invention has for its object a method indicate with which the above Disadvantages can be avoided.

Gelöst wird diese Aufgabe durch ein Verfahren mit den Merkmalen des Patentanspruches 1 oder mit den Merkmalen des Patentanspruches 3.This task is solved by a method with the characteristics of claim 1 or with the features of the claim Third

Beim erfindungsgemäßen Verfahren wird weder die Zufuhr von Versiegelungsmasse noch die Bewegung der Versiegelungsdüse oder die Bewegung ihrer normal zur Ebene der Isolierglasscheibe ausgerichteten Achse unterbrochen. Die Versiegelungsdüse fährt also um die Ecke der Isolierglasscheibe herum, wobei der Austritt von Versiegelungsmasse aus der Versiegelungsdüse nicht unterbrochen wird, so dass zum einen ein schnelleres Arbeiten möglich ist und zum anderen die erwähnten fehlerhaften Stellen in der Versiegelung nicht auftreten können. Weiters können Dosierungenauigkeiten, die insbesondere beim Unterbrechen und Wiederaufnehmen des Austritts von Versiegelungsmasse aus der Versiegelungsdüse auftreten können, zuverlässig verhindert werden, so dass sich ein exaktes Füllen der Randfuge auch im Eckbereich einer Isolierglasscheibe durchführen läßt.In the method according to the invention, neither the supply of Sealing compound still the movement of the sealing nozzle or the movement of their normal to the level of the insulating glass pane aligned axis interrupted. The sealing nozzle So drives around the corner of the insulating glass pane, the Sealing compound escapes from the sealing nozzle is not interrupted, so that on the one hand a faster Work is possible and secondly the faulty mentioned Spots in the seal cannot occur. Furthermore, can dosing inaccuracies, especially when interrupting and resuming the exit of Sealing compound can occur from the sealing nozzle, can be reliably prevented, so that an exact filling the edge joint also in the corner area of an insulating glass pane can be carried out.

Die Bewegungsbahn der Achse der Versiegelungsdüse im Bereich einer Ecke einer Isolierglasscheibe ist bogenförmig, wobei die Bewegungsbahn bei in die Randfuge der Isolierglasscheibe eintauchenden Versiegelungsdüsen im Bereich der Ecken innerhalb des Außenrandes der Isolierglasscheibe verläuft. Bei auf den Kanten der beiden die Randfugen begrenzenden Glasscheiben gleitenden Versiegelungsdüsen wird eine Bewegungsbahn der Achse der Versiegelungsdüse gewählt, die im Bereich der Ecken der Isolierglasscheibe außerhalb des Außenrandes der Isolierglasscheibe liegt und schlaufenförmig vom Rand der Isolierglasscheibe weg und wieder zum Rand der Isolierglasscheibe zurück verläuft. In beiden Fällen wird die Versiegelungsdüse federnd in Anläge an den Rand der Isolierglasscheibe gehalten.The trajectory of the axis of the sealing nozzle in the area one corner of an insulating glass pane is arched, the Path of movement when entering the edge joint of the insulating glass pane Sealing nozzles in the area of the corners inside the outer edge of the insulating glass pane. At the Edges of the two glass panes delimiting the edge joints sliding sealing nozzles becomes a trajectory of movement Axis of the sealing nozzle chosen in the area of the corners the insulating glass pane outside the outer edge of the insulating glass pane lies and forms a loop from the edge of the insulating glass pane away and back to the edge of the insulating glass pane runs back. In both cases, the sealing nozzle held resiliently in contact with the edge of the insulating glass pane.

Dies kann bevorzugt noch dadurch verbessert werden, dass in Bewegungsrichtung vor der Versiegelungsdüse die Tiefe der Randfuge erfasst wird und dass das Volumen der Randfuge im Eckbereich auf Grund der vor und nach dem Eckbereich Tiefe der Randfuge berechnet und während der Bewegung der Versiegelungsdüse um eine Ecke einer Isolierglasscheibe eine entsprechende Menge an Versiegelungsmasse zugeführt wird. Bei dieser Ausführungsform des erfindungsgemäßen Verfahrens wird die erforderliche Menge an Versiegelungsmasse genau erfasst und die Zufuhr von Versiegelungsmasse kann demgemäß noch genauer gesteuert werden. This can preferably be improved further in that Direction of movement in front of the sealing nozzle the depth of the Edge joint is recorded and that the volume of the edge joint in Corner area due to the depth before and after the corner area the edge joint is calculated and while the sealing nozzle is moving a corresponding one around a corner of an insulating glass pane Amount of sealant is supplied. At this Embodiment of the method according to the invention is the required amount of sealing compound exactly recorded and the supply of sealing compound can accordingly be even more precise to be controlled.

Auch im Eckbereich, wenn sich die Versiegelungsdüse also um eine Ecke der Isolierglasscheibe ohne anzuhalten herumbewegt, kann die Relativgeschwindigkeit zwischen Versiegelungsdüse und Isolierglasscheibe und die aktuelle Fördermenge von Versiegelungsmasse so gesteuert (verändert) werden, wie dies an sich aus der US 4 973 435 A und der US 5 136 974 A bekannt ist, um den gewünschten Füllgrad der Randfuge mit Versiegelungsmasse zu erreichen.Even in the corner area when the sealing nozzle is around moved a corner of the insulating glass pane without stopping, can the relative speed between the sealing nozzle and Insulating glass pane and the current flow rate of sealing compound be controlled (changed) as this in itself from US 4 973 435 A and US 5 136 974 A, um the desired degree of filling of the edge joint with sealing compound to reach.

Wie ebenfalls aus den genannten Schriften bekannt, wird die Relativbewegung zwischen Versiegelungsdüse und Isolierglasscheibe erreicht, indem die Versiegelungsdüse entlang der stillstehenden Isolierglasscheibe und/oder die Isolierglasscheibe bei stillstehender Versiegelungsdüse bewegt wird.As is also known from the cited documents, the Relative movement between the sealing nozzle and the insulating glass pane achieved by the sealing nozzle along the stationary insulating glass pane and / or the insulating glass pane is moved with the sealing nozzle at a standstill.

Das erfindungsgemäße Verfahren ist für Ein-Düsen-Versiegelungsautomaten ebenso geeignet wie für Versiegelungsautomaten mit zwei oder mehr als zwei Versiegelungsdüsen.The method according to the invention is for one-nozzle automatic sealing machines just as suitable as for automatic sealing machines with two or more than two sealing nozzles.

Da die Bewegungsbahn der Achse in einer Ausführungsform bogenförmig innerhalb der Isolierglasscheibe verläuft und somit die Ecke praktisch "abgeschnitten" wird und in einer anderen Ausführungsform außerhalb der Umfangskontur der Isolierglasscheibe liegt, also sich nach einer im Bereich der Ecke schlaufenförmigen Bahn bewegt, wogegen die Versiegelungsdüse die Ecke vollständig umfahren muß, wird der Abstand zwischen der Versiegelungsdüse und der Achse zur Ecke hin zunehmend größer bzw. kleiner und nach der Ecke wieder kleiner bzw. größer, bis die Versiegelungsdüse mit der Achse wieder fluchtet. Diese Bewegung der Versiegelungsdüse relativ zur Achse kann beispielsweise gegen die Kraft einer Feder erfolgen. Because the trajectory of the axis is arched in one embodiment runs inside the insulating glass pane and thus the Corner is practically "cut off" and in another embodiment outside the circumferential contour of the insulating glass pane lies, i.e. after a loop-shaped in the area of the corner Web moves, whereas the sealing nozzle turns the corner must be bypassed completely, the distance between the sealing nozzle and the axis towards the corner increasingly larger or smaller and after the corner again smaller or larger until the sealing nozzle is aligned with the axis again. This Movement of the sealing nozzle relative to the axis can, for example against the force of a spring.

This is over the US 5 136 974 A known per se.

    Die Führungsschiene für die Halterung des Düsenkopfes 53 kann vor oder hinter der Stützwand 50 angeordnet sein.The guide rail for holding the nozzle head 53 can be arranged in front of or behind the support wall 50.

    Das erfindungsgemäße Verfahren ist nicht auf Versiegelungsautomaten beschränkt, in welchen die Isolierglasscheibe 51 beim Versiegeln im wesentlichen vertikal steht, sondern sie kann auch an Horizontalversiegelungsautomaten, in welchen die Isolierglasscheibe 51 auf einem Tisch horizontal aufliegt, verwendet werden.The method according to the invention is not on automatic sealing machines in which the insulating glass pane 51 is essentially vertical when sealing, but instead can also be used on horizontal sealing machines in which the Insulating glass pane 51 lies horizontally on a table, be used.

    Der Düsenkopf 53 besteht aus einem Träger 1, der an der Halterung 54 befestigt ist, die an der Führung des Versiegelungsautomaten im wesentlichen vertikal auf und ab verschiebbar geführt ist.The nozzle head 53 consists of a carrier 1, which is on the bracket 54 is attached to the guide of the sealing machine essentially vertically up and down is led.

    An dem Träger 1 ist um eine Achse, die parallel zur Ebene der Isolierglasscheibe 51 ausgerichtet ist, verschwenkbar ein Arm 3 montiert, der an seinem freien Ende die Düse 4 trägt. Der Arm 3, der die Versiegelungsdüse 4 trägt, ist mit Hilfe eines Pneumatikzylinders 5 verschwenkbar, damit die Düse 4 an den Rand der zu versiegelnden Isolierglasscheibe 51 elastisch federnd anlegbar und von diesem wieder abhebbar ist.On the carrier 1 is about an axis that is parallel to the plane of the Insulating glass pane 51 is aligned, an arm pivotable 3 mounted, which carries the nozzle 4 at its free end. The Arm 3, which carries the sealing nozzle 4, is by means of a Pneumatic cylinder 5 pivotable so that the nozzle 4 to the Edge of the insulating glass pane 51 to be sealed is elastic can be resiliently applied and lifted off again.

    Der Träger 1 ist um eine zur Ebene der Isolierglasscheibe 51 senkrechte Achse verdrehbar an der Halterung 54 befestigt.The carrier 1 is around one to the level of the insulating glass pane 51 vertical axis rotatably attached to the bracket 54.

    Die der Isolierglasscheibe 51 zugekehrte Fläche des Düsenplättchens 11 berührt im Bereich der Düsenöffnung diese Achse.The surface of the nozzle plate facing the insulating glass pane 51 11 touches this axis in the area of the nozzle opening.

    An dem Träger 1 kann weiters ein Abstreifplättchen befestigt sein, das mit Hilfe eines Pneumatikzylinders senkrecht zur Ebene der Isolierglasscheibe 51 vor- und zurückschiebbar ist. Zum Bewegen des Plättchens quer zu seiner Ebene ist ein weiterer Zylinder vorgesehen, dessen Kolben den Zylinder trägt.A wiper plate can also be attached to the carrier 1 be that with the help of a pneumatic cylinder perpendicular to The level of the insulating glass pane 51 can be pushed back and forth. Another is to move the tile across its plane Cylinder provided, the piston of which carries the cylinder.

Die Düse 4 ist eine beispielsweise ballige Düse, d.h. das Düsenplättchen 11 ist an seiner der Isolierglasscheibe 51 zugekehrten Seite konvex gewölbt.The nozzle 4 is at the front end of the arm 3, for example With the aid of a fastening device having a leaf spring 9 established. The nozzle 4 is a spherical one, for example Nozzle, i.e. the nozzle plate 11 is on the insulating glass pane 51 facing side convex.

    Am Düsenkopf 53 ist bevorzugt über einen Hilfsrahmen 34, der um einen zur Schwenkachse des Armes 3 für die Düse 4 parallele Achse verschwenkbar am Träger 1 gelagert ist, ein Tiefentaster 22 vorgesehen. Zum Verschwenken des Hilfsrahmens 20 ist ein Pneumatikzylinder vorgesehen.At the nozzle head 53 is preferably via an auxiliary frame 34, the about a parallel to the pivot axis of the arm 3 for the nozzle 4 Axis pivotally mounted on the carrier 1, a depth switch 22 provided. To pivot the subframe 20 is a Pneumatic cylinder provided.

In Abhängigkeit von der Tiefe der Randfuge wird die Geschwindigkeit der Relativbewegung zwischen Isolierglasscheibe 51 und Düse 4 und/oder die Menge an Versiegelungsmasse, die aus der Düse 4 in die Randfuge ausgepresst wird, gesteuert.With the help of the ruler assigned to the depth probe 22 the deflection of the depth probe 22 is detected, so that the depth of the edge joint of the insulating glass pane to be sealed 51 can be measured. Depending on the depth of the Edge joint is the speed of the relative movement between Insulating glass pane 51 and nozzle 4 and / or the amount of sealing compound, which are pressed out of the nozzle 4 into the edge joint is controlled.

    Die Relativbewegung zwischen Düse 4 und Isolierglasscheibe 51 wird durch Auf- und Abbewegen des Trägers 1 für die Düse 4, Verdrehen derselben um die zur Isolierglasscheibe 51 senkrechte Achse und/oder Bewegen der Isolierglasscheibe 51 selbst ausgeführt.The relative movement between nozzle 4 and insulating glass pane 51 by moving the support 1 for the nozzle 4 up and down, Rotate the same about the perpendicular to the insulating glass pane 51 Axis and / or moving the insulating glass pane 51 itself executed.

    Das Schwenken der Düse 4 um die senkrecht zur Isolierglascheibe 6 ausgerichtete Achse wird mit Hilfe einer mit dem Düsenkopf 53 verbundenen Zahnscheibe 25, in die das Ritzel eines Antriebsmotors 26 eingreift, ausgeführt.The pivoting of the nozzle 4 perpendicular to the insulating glass pane 6 aligned axis with the help of a nozzle head 53 connected toothed disc 25, into which the pinion one Drive motor 26 engages, executed.

    Die zuvor anhand der Fig. 1 und 2 beschriebene Ausführungsform einer Versiegelungsvorrichtung, insbesondere des Düsenkopfes 53, ist nur als Beispiel für eine zum Durchführen des erfindungsgemäßen Verfahrens geeignete Vorrichtung zu verstehen.The embodiment previously described with reference to FIGS. 1 and 2 a sealing device, especially the nozzle head 53 is only an example of one for performing the invention To understand the method suitable device.

    Beispielsweise kann der Tiefentaster 22, statt an einem verschwenkbaren Arm am Düsenkopf 53 montiert zu sein, um eine zur Ebene der Isolierglasscheibe 51 normale Achse verdrehbar sein, um die Tiefe der Randfuge zu erfassen.For example, the depth switch 22 can be used instead of a pivotable one Arm to be mounted on the nozzle head 53 to one for Plane of the insulating glass pane 51 normal axis can be rotated, to measure the depth of the edge joint.

    Zum Erfassen der Tiefe der Randfuge der Isolierglasscheibe 51, also des Abstandes zwischen der außen liegenden Fläche des Abstandhalterrahmens und den Außenrändern der beiden Glasscheiben der Isolierglasscheibe 51 können auch andere Vorrichtungen, z.B. Sensoren, vorgesehen sein, die bevorzugt am Düsenkopf 53 angeordnet sind.To measure the depth of the edge joint of the insulating glass pane 51, ie the distance between the outer surface of the Spacer frame and the outer edges of the two glass panes the insulating glass pane 51 can also other devices, e.g. Sensors may be provided, which are preferably on Nozzle head 53 are arranged.

Im Bereich der zur Ecke 61 führenden Ränder 60 der beiden Glasscheiben wird der Düsenkopf 53 so ausgerichtet, dass dessen Schwenkachse im wesentlichen in einer Bahn bewegt wird, die mit den Rändern 60 zusammenfällt. Im Bereich der Ecke 61 selbst wird der Düsenkopf 53 so bewegt, dass die Bewegungsbahn 70 im Bereich der Ecke 61 außerhalb der Isolierglasscheibe 51 verläuft und, wie in Fig. 3 gezeigt, etwa schlaufenförmig ist. Dadurch und durch die beschriebene elastisch federnde Lagerung der Düse 4 am Düsenkopf 53 werden die Reibungskräfte zwischen dem Düsenplättchen 11 und den Rändern 60 der beiden Glasscheiben der Isolierglasscheibe 51 so weit verringert, dass nicht nur die Düse 4 problemlos um die Ecke herumgeschwenkt werden kann, ohne angehalten zu werden. Auch die Reibungskräfte zwischen Düsenplättchen 11 und Isolierglasscheibe 51 werden so verringert, so dass ein vorzeitiges Abnützen des Düsenplättchens 11 vermieden ist.3 is the course of the movement path of the axis of rotation, um which the nozzle 4 is rotatably mounted on its holder, when driving around a corner 61 of the insulating glass pane 51 for the Case of a spherical nozzle 4 shown, the nozzle plate 11 on the inner edges of the two glass panes of the insulating glass pane 51 is moved adjacent.
