Description

Die Erfindung betrifft ein Verfahren zur Randfugenversiege­lung einer Isolierglaseinheit, insbesondere einer Kraftfahr­zeug-Isolierglaseinheit, die eine Innenscheibe, eine Außen­scheibe und eine Randfuge aufweist, wobei die Randfuge mit einem Kleber gefüllt und im Randbereich eine glatte Fläche gebildet wird. Die Erfindung betrifft außerdem Werkzeugaggre­gate zur Durchführung eines solchen Verfahrens. Der Kleber kann in der Randfuge zugleich als Abstandshalter dienen. Der Kleber kann aber auch einem Abstandshalter nach außen hin vorgeschaltet sein. Der Kleber ist zumeist ein Kleber auf Kunstharzbasis. Handelt es sich um eine Kraftfahrzeug-Iso­lierglaseinheit, insbesondere um eine solche, die im montier­ten Zustand verschiebbar ist, so ist eine über den Rand der Innenscheibe zumindest bereichsweise mit einem Überstands­streifen vorstehende Außenscheibe vorgesehen. Hier dient der Überstandsstreifen der Führung der Kraftfahrzeugscheibe im montierten Zustand (DE-OS 35 17 581).The invention relates to a method for sealing edge joints of an insulating glass unit, in particular a motor vehicle insulating glass unit, which has an inner pane, an outer pane and an edge joint, the edge joint being filled with an adhesive and a smooth surface being formed in the edge region. The invention also relates to tool assemblies for carrying out such a method. The adhesive can also serve as a spacer in the edge joint. The adhesive can, however, also be connected upstream of a spacer. The adhesive is mostly an adhesive based on synthetic resin. If it is a motor vehicle insulating glass unit, in particular one which is displaceable in the assembled state, an outer pane projecting over the edge of the inner pane at least in regions with a protruding strip is provided. Here the protrusion strip serves to guide the motor vehicle window in the assembled state (DE-OS 35 17 581).

Das bekannte Verfahren, von dem die Erfindung ausgeht (DE-OS 37 02 402), bezieht sich auf die Behandlung von Iso­lierglaseinheiten, die, wie vorstehend alternativ beschrie­ben, einen Überstandsstreifen aufweisen. Dabei wird die glat­te Sichtfläche zwischen Innenscheibe und Außenscheibe im Be­reich des Überstandsstreifen durch eine besondere Sichtblen­de in Form einer Profilleiste, die in die Randfuge einge­setzt wird, gebildet. Das ist aufwendig und in einer moder­nen automatischen Produktionslinie nicht einfach zu verwirk­lichen, insbesondere wenig roboterapplikabel.The known method from which the invention is based (DE-OS 37 02 402) relates to the treatment of insulating glass units which, as described alternatively above, have a protruding strip. The smooth visible surface between the inner pane and the outer pane in the area of the protrusion strip is formed by a special screen in the form of a profile strip which is inserted into the edge joint. This is complex and not easy to implement in a modern automatic production line, especially with few robot applications.

Die Erfindung liegt die Aufgabe zugrunde, das eingangs be­schriebene Verfahren so zu führen, daß auf einfache Weise und unter Verzicht auf eine zusätzliche Profilleiste eine glatte Fläche im Bereich der Randfuge gebildet werden kann. Der Erfindung liegt fernerhin die Aufgabe zugrunde, Werkzeug­aggregate anzugeben, die für die Durchführung des erfindungs­gemäßen Verfahrens besonders geeignet sind.The invention has for its object to carry out the method described above so that a smooth surface can be formed in the area of the edge joint in a simple manner and without an additional profile strip. The invention is also based on the object of specifying tool assemblies which are particularly suitable for carrying out the method according to the invention.

Zur Lösung dieser Aufgabe lehrt die Erfindung in verfahrens­mäßiger Hinsicht, daß die Randfuge im Überschuß mit dem Kle­ber gefüllt sowie der Kleber einschließlich der Überschuß­massen zur ausreichenden Erhärtung gebracht wird und daß die Überschußmassen durch zumindest ein mechanisches Werkzeug, welches relativ zum Rand der Isolierglaseinheit bewegt wird, abgetragen wird. Wenn die Isolierglaseinheit eine über den Rand der Innenscheibe zumindest bereichsweise mit einem Über­standsstreifen überstgehende Außenscheibe aufweist, so lehrt die Erfindung, daß die Überschußmassen auf dem Überstands­streifen zur Erhärtung gebracht werden und daß durch das Ab­tragen der Überschußmassen mit dem mechanischen Werkzeug im Bereich des Überstandsstreifens eine glatte Sichtfläche ge­bildet wird. In der Formulierung, daß das Werkzeug relativ zum Rand der Isolierglaseinheit bewegt wird, kommt zum Aus­druck, daß die Isolierglaseinheit und/oder das Werkzeug be­wegt werden können. Die Maßnahme, die Sichtfläche des Kle­bers im Bereich zwischen einer Innenscheibe und einer Außen­scheibe einer Isolierglaseinheit mit Hilfe eines Werkzeuges zu glätten, ist an sich bekannt (DE-OS 22 20 512), jedoch wird hier das noch nicht ausgehärtete Material durch einen besonderen Schuh glattgestrichen. Das verlangt eine sehr ge­naue Dosierung des Klebers beim Einbringen in die Randfuge, da anders durch Überschußmasse Unebenheiten und Veränderungen entstehen.In order to achieve this object, the invention teaches in procedural terms that the edge joint is filled with the adhesive in excess and the adhesive including the excess materials is sufficiently hardened and that the excess materials are at least one mechanical tool which is moved relative to the edge of the insulating glass unit, is removed. If the insulating glass unit has an outer pane protruding over the edge of the inner pane at least in regions with a protrusion strip, the invention teaches that the excess masses on the protrusion strip are hardened and that a smooth surface is removed by removing the excess masses with the mechanical tool in the region of the protrusion strip Visible surface is formed. The wording that the tool is moved relative to the edge of the insulating glass unit expresses that the insulating glass unit and / or the tool can be moved. The measure of smoothing the visible surface of the adhesive in the area between an inner pane and an outer pane of an insulating glass unit with the aid of a tool is known per se (DE-OS 22 20 512), but here the material which has not yet cured is used by a special shoe smoothed. This requires a very precise metering of the adhesive when it is introduced into the edge joint, since otherwise unevenness and changes result from excess mass.

Die Erfindung geht von der Erkenntnis aus, daß eine glatte Fläche an einem erhärteten Kunstharzkleber durch mechanisches Abarbeiten gebildet werden kann. Die Erfindung schafft die Voraussetzung für die Erzeugung einer glatten Fläche bzw. Sichtfläche bei einer Isolierglaseinheit im Randfugenbereich zunächst dadurch, daß die Randfuge im Überschuß mit dem Kle­ber gefüllt wird und der Kleber einschließlich der Über­schußmasse zur ausreichenden Erhärtung gebracht wird. Die glatte Fläche bzw. Sichtfläche selbst wird durch mechanisches Abarbeiten dieser Überschußmasse gebildet. Das kann auf ver­schiedene Weise erfolgen, beispielsweise durch einen geeigne­ten ausgebildeten rotierenden Fräser oder rotierende Bürsten, die gleichzeitig Glätten und Reinigen. Besonders einfach und funktionssicher arbeitet bei der Ausführungsform mit Über­standsstreifen eine bevorzugte erfindungsgemäße Verfahrens­weise, die dadurch gekennzeichnet ist, daß längs des Randes der Innenscheibe und auf dem Überstandsstreifen jeweils ein Schneidmesser mit federnder Anlage geführt und mit den Schneidmessern die Überschußmassen schneidend abgetragen wer­den und daß danach die Schnittflächen des Klebers und der Rand der Innenscheibe sowie der Überstandsstreifen mit zu­mindest einer rotierenden Bürste geglättet und gereinigt wird. Bei dieser Ausführungsform ist sichergestellt, daß we­der der Rand der Innenscheibe noch der Überstandsstreifen der Außenscheiße durch die Werkzeuge eine Beschädigung erfahren. Es versteht sich, daß beim Arbeiten der rotierenden Werkzeu­ge eine geeignete Reinigungsmittellösung beigegeben werden kann. Je nach dem Aufbau des Klebers und je nach der werk­stoffmäßigen Einstellung der Innenscheibe bzw. der Außen­scheibe der Isolierglaseinheit besteht auch die Möglichkeit, lediglich mit Bürsten zu arbeiten. Dazu lehrt die Erfindung, daß die Überschußmassen durch zumindest eine rotierende Bürste mit ausreichend harten Borsten, die mit einer zur Ebe­ne der Isolierglaseinheit schräggestellten Achse sowie mit Borsten, die bei kleberfreier Randfuge einfassen würden, rotiert, abgetragen werden. Eine zweite Bürste kann nachge­schaltet sein.The invention is based on the knowledge that a smooth surface can be formed on a hardened synthetic resin adhesive by mechanical processing. The invention creates the prerequisite for producing a smooth surface or visible surface in an insulating glass unit in the edge joint area first by filling the edge joint in excess with the adhesive and bringing the adhesive, including the excess mass, to sufficient hardening. The smooth surface or visible surface itself is formed by mechanical processing of this excess mass. This can be done in various ways, for example by a suitably designed rotating milling cutter or rotating brushes, which simultaneously smooth and clean. A preferred procedure according to the invention works particularly simply and functionally reliably in the embodiment with protrusion strips, which is characterized in that a cutting knife with resilient contact is guided along the edge of the inner pane and on the protrusion strip and the excess masses are removed by cutting with the cutting blades and after that the Cut surfaces of the adhesive and the edge of the inner pane and the protruding strip are smoothed and cleaned with at least one rotating brush. In this embodiment it is ensured that neither the edge of the inner pane nor the protruding strip of the External shit can be damaged by the tools. It is understood that a suitable cleaning agent solution can be added when working the rotating tools. Depending on the structure of the adhesive and the material settings of the inner pane or the outer pane of the insulating glass unit, there is also the option of working only with brushes. To this end, the invention teaches that the excess masses are removed by at least one rotating brush with sufficiently hard bristles, which rotates with an axis inclined to the level of the insulating glass unit and with bristles which would enclose in the case of an adhesive-free edge joint. A second brush can be connected downstream.

Die Begriffe Innenscheibe und Außenscheibe differenzieren bei der Darstellung der Erfindung die beiden Scheiben, aus denen die Isolierglaseinheit gebildet ist. Handelt es sich um eine Kraftfahrzeug-Isolierglaseinheit, so ist die im Rahmen der Erfindung als Außenscheibe bezeichnete Scheibe im eingebauten Zustand der Isolierglaseinheit regelmäßig auch nach außen hin angeordnet. Das schließt nicht aus, daß eine nach dem erfin­dungsgemäßen Verfahren hergestellte Isolierglaseinheit auch gleichsam umgekehrt montiert wird.In the representation of the invention, the terms inner pane and outer pane differentiate the two panes from which the insulating glass unit is formed. If it is a motor vehicle insulating glass unit, the pane referred to as the outer pane in the context of the invention is also arranged on the outside in the installed state of the insulating glass unit. This does not rule out that an insulating glass unit manufactured according to the method according to the invention is also installed in reverse order.

Die Rotations­richtungen der Bürsten 16, 17 wurden durch entsprechende Bogenpfeile gekennzeichnet. Überlicherweise ist eine Roboterauf­nahme vorgesehen, die nicht gezeichnet, wurde. Es versteht sich, daß die Bürstenaggregate Antriebs- und Steuereinrich­tungen aufweisen, was ebenfalls nicht gezeichnet wurde.4 shows a brush unit 16 which is set up to carry out the method according to the invention. It is characterized by a first rotating brush 16 in the machining direction, which rotates with an axis 18 inclined to the level of the insulating glass unit 9 and with bristles 19 which would enclose the edge joint 13 in the case of an adhesive-free edge joint 13. One recognizes a second brush 17 in the machining direction, which was shown in FIG. 5 and which rotates about an axis 20 parallel to the plane of the insulating glass unit 9 and applies bristles 21 to the edge of the inner pane 11 and to the protruding strip 8.
