Definitions
- 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 protruding at least partially over the edge of the inner pane with a protruding strip and an edge joint, the edge joint being filled with an adhesive in such a way that excess adhesive compound rests on the protrusion strip, where it is hardened, a cutting knife with resilient contact being guided along the edge of the inner pane and the excess adhesive material being removed with the cutting knife along the edge of the inner pane and the edge joint.
- the adhesive can also serve as a spacer in the edge joint. However, the adhesive can also be connected upstream of a spacer.
- the adhesive is mostly an adhesive based on synthetic resin.
- an outer pane protruding over the edge of the inner pane at least in regions with a protruding strip is provided.
- the protrusion strip serves to guide the motor vehicle window in the assembled state (DE-OS 35 17 581).
- the known method from which the invention is based (US-A-4,145,171) describes the treatment of insulating glass units which have a protruding strip.
- the edge joint is filled with an adhesive, the excess adhesive mass resting on the overlap strip.
- the hardening adhesive is cut off by means of two knives which are spring-guided on the edges of the inner and outer pane.
- the edge joint has a step-shaped cut edge.
- 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 also known from DE-OS 22 20 512, but here the not yet hardened material is smoothed out by a special shoe. This requires a very precise metering of the adhesive when penetrating into the edge joint, since otherwise unevenness and changes arise from excess adhesive compound.
- 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 teaches in procedural terms that a further cutting knife with resilient contact is guided on the protrusion strip and the excess adhesive mass is removed by cutting on the protrusion strip, and then the cut surface of the adhesive and the edge of the inner pane and the Survival strips are smoothed and cleaned with at least one rotating brush.
- 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 prerequisites 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 adhesive and bringing the adhesive, including the excess mass, to sufficient hardening.
- the smooth surface or visible surface itself is formed by mechanically working off this excess mass. This can be done in different ways, for example by a suitably designed rotating milling cutter or rotating brushes that smooth and clean at the same time.
- the method according to the invention ensures that neither the edge of the inner pane nor the protruding strip External shit can be damaged by the tools. It is understood that a suitable cleaning agent solution can be added when working with the rotating tools.
- the invention teaches that the excess mass is rotatably removed by at least one rotating brush with bristles which are sufficiently hard and which are rotated with an axis inclined to the level of the insulating glass unit and with bristles which would border if the edge joint was free of adhesive.
- a second brush can be connected downstream.
- 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 an 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 exclude that an insulating glass unit manufactured according to the method according to the invention is also installed in reverse order.
- the exemplary embodiment relates to the treatment of an insulating glass unit which has an outer pane projecting over the edge of the inner pane at least in regions with a protruding strip.
- the cutting unit shown in Figures 1 to 3 is characterized by a tool holder 1, a rubber metal element 2 connected to the tool holder 1, which is elastically adjustable against the plane of the insulating glass unit 9 and parallel thereto, and a spring plate 4, which is arranged under the rubber metal element 2 is.
- the spring plate 4 carries two cutting knives 6, 7.
- the cutting knife 6 guided on the protrusion strip 8 of the insulating glass unit 9 is designed as a knife wedge. But that too Edge 10 of the inner pane 11 of the insulating glass unit 9 guided cutting knife 7 could be wedge-shaped.
- a robot receptacle 12 can be seen which allows the cutting unit to be used in a production line which is equipped with robots.
- FIG 2 shows the cutting unit when carrying out the method according to the invention. It was indicated that the edge joint 13 was filled in excess with the adhesive 14, the adhesive including the excess mass 15 being brought to sufficient hardening. It can be seen that the hardened excess mass 15 is removed with the cutting knives 6, 7 described.
- FIG. 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.
- 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 with its bristles 21 acts on the edge of the inner pane 11 and the protruding strip 8.
- the directions of rotation of the brushes 16, 17 were identified by corresponding curved arrows.
- a robot mount is usually provided, which was not drawn. It is understood that the brush units have drive and control devices, which was also not drawn.
- the first brush 16 can be equipped with relatively hard bristles 19 and, to that extent, can roughly work.
- the sum of the bristles can have a ridge-shaped profile in radial section, as was indicated by dash-dotted lines in FIG. 4.
- the brush 17 has soft bristles 21 and works as it were finishing. - Even when working with two identical brushes, the bristles can have different hardness.
- Figures 6 and 7 illustrate that one can also work with so-called copy brushes 22. This is particularly important for automatic production lines and when using robots.
- the copying brushes are guided with copying rollers 23 on the insulating glass units 9.
- the copying roller 23 could also be guided under the insulating glass unit 9, in particular under the protruding strip 8.
Description
Die Erfindung betrifft ein Verfahren zur Randfugenversiegelung einer Isolierglaseinheit, insbesondere einer Kraftfahrzeug-Isolierglaseinheit, die eine Innenscheibe, eine über den Rand der Innenscheibe zumindest bereichsweise vorstehende Außenscheibe mit einem Überstandsstreifen sowie eine Randfuge aufweist, wobei die Randfuge mit einem Kleber so gefüllt wird, daß Überschußklebermasse auf dem Überstandsstreifen aufliegt, wo sie zur Erhärtung gebracht wird, wobei längs des Randes der Innenscheibe ein Schneidmesser mit federnder Anlage geführt und mit dem Schneidmesser die Überschußklebermasse längs des Randes der Innenscheibe und der Randfuge schneidend abgetragen wird. 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-Isolieglaseinheit, 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 protruding at least partially over the edge of the inner pane with a protruding strip and an edge joint, the edge joint being filled with an adhesive in such a way that excess adhesive compound rests on the protrusion strip, where it is hardened, a cutting knife with resilient contact being guided along the edge of the inner pane and the excess adhesive material being removed with the cutting knife along the edge of the inner pane and the edge joint. The adhesive can also serve as a spacer in the edge joint. However, the adhesive can 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 that is displaceable in the assembled state, an outer pane protruding 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 (US-A-4,145,171), beschreibt eine Behandlung von Isolierglaseinheiten, die einen Überstandsstreifen aufweisen. Hierbei wird die Randfuge mit einem Kleber gefüllt, wobei die Überschußklebermasse auf dem Überstandsstreifen aufliegt. Der erhärtende Kleber wird mittels zweier, an den Rändern der Innen- und Außenscheibe federnd geführter Messer abgeschnitten. Hierdurch kann jedoch der Überstandsstreifen nicht vom anhaftenden Kleber befreit werden. Weiterhin weist die Randfuge eine stufenförmige Schnittkante auf.The known method from which the invention is based (US-A-4,145,171) describes the treatment of insulating glass units which have a protruding strip. Here the edge joint is filled with an adhesive, the excess adhesive mass resting on the overlap strip. The hardening adhesive is cut off by means of two knives which are spring-guided on the edges of the inner and outer pane. However, this means that the protruding strip cannot be freed from the adhesive that adheres to it. Furthermore, the edge joint has a step-shaped cut edge.
Die Maßnahme, die Sichtfläche des Klebers im Bereich zwischen einer Innenscheibe und einer Außenscheibe einer Isolierglaseinheit mit Hilfe eines Werkzeuges zu glätten, ist weiterhin aus DE-OS 22 20 512 bekannt, jedoch wird hier das noch nicht ausgehärtete Material durch einen besonderen Schuh glattgestrichen. Das verlangt eine sehr genaue Dosierung des Klebers beim Eindringen in die Randfuge, da anders durch Überschußklebermasse Unebenheiten und Veränderungen entstehen.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 also known from DE-OS 22 20 512, but here the not yet hardened material is smoothed out by a special shoe. This requires a very precise metering of the adhesive when penetrating into the edge joint, since otherwise unevenness and changes arise from excess adhesive compound.
Bei einem weiteren bekannten Verfahren (DE-OS 37 02 402) wird die glatte Sichtfläche zwischen Innenscheibe und Außenscheibe im Bereich des Überstandsstreifens 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.In another known method (DE-OS 37 02 402), the smooth visible surface between the inner pane and the outer pane in the area of the protruding 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.
Der Erfindung liegt die Aufgabe zugrunde, das eingangs beschriebenen 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.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.
Zur Lösung dieser Aufgabe lehrt die Erfindung in verfahrensmäßiger Hinsicht, daß auf dem Überstandsstreifen ein weiteres Schneidmesser mit federnder Anlage geführt wird und mit dem weiteren Schneidmesser die Überschußklebermasse auf dem Überstandsstreifen schneidend abgetragen wird, sowie danach die Schnittfläche des Klebers und der Rand der Innenscheibe sowie der Überstandsstreifen mit zumindest einer rotierenden Bürste geglättet und gereinigt wird.In order to achieve this object, the invention teaches in procedural terms that a further cutting knife with resilient contact is guided on the protrusion strip and the excess adhesive mass is removed by cutting on the protrusion strip, and then the cut surface of the adhesive and the edge of the inner pane and the Survival strips are smoothed and cleaned with at least one rotating brush.
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 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. Durch das erfindungsgemäße Verfahren 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 Überschußmasse 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, rotierend 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 prerequisites 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 adhesive and bringing the adhesive, including the excess mass, to sufficient hardening. The smooth surface or visible surface itself is formed by mechanically working off this excess mass. This can be done in different ways, for example by a suitably designed rotating milling cutter or rotating brushes that smooth and clean at the same time. The method according to the invention ensures that neither the edge of the inner pane nor the protruding strip External shit can be damaged by the tools. It is understood that a suitable cleaning agent solution can be added when working with the rotating tools. Depending on the structure of the adhesive and the material-specific setting of the inner pane or the outer pane of the insulating glass unit, it is also possible to work only with brushes. To this end, the invention teaches that the excess mass is rotatably removed by at least one rotating brush with bristles which are sufficiently hard and which are rotated with an axis inclined to the level of the insulating glass unit and with bristles which would border if the edge joint was free of adhesive. 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 an 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 exclude that an insulating glass unit manufactured according to the method according to the invention is also installed in reverse order.

Das in den Figuren 1 bis 3 dargestellte Schneidaggregat ist gekennzeichnet durch einen Werkzeughalter 1, ein mit dem Werkzeughalter 1 verbundenes Gummimetallelement 2, welches gegen die Ebene der Isolierglaseinheit 9 und parallel dazu elastisch verstellbar ist, und ein Federblech 4, welches unter dem Gummimetallelement 2 angeordnet ist. Das Federblech 4 trägt zwei Schneidmesser 6, 7. Im Ausführungsbeispiel ist das auf dem Überstandsstreifen 8 der Isolierglaseinheit 9 geführte Schneidmesser 6 als Messerkeil ausgeführt. Aber auch das am Rand 10 der Innenscheibe 11 der Isolierglaseinheit 9 geführte Schneidmesser 7 könnte keilförmige gestaltet sein.

Mann erkennt eine in Bearbeitungsrichtung zweite Bürste 17, die in Fig. 5 dargestellt wurde und die um eine zur Ebene der Isolierglaseinheit 9 parallele Achse 20 rotiert und mit ihren Borsten 21 den Rand der Innenscheibe 11 sowie den Überstandsstreifen 8 beaufschlagt. Die Rotationsrichtungen der Bürsten 16, 17 wurden durch entsprechende Bogenpfeile gekennzeichnet. Überlicherweise ist eine Roboteraufnahme vorgesehen, die nicht gezeichnet, wurde.
