Abstract

The glass panels are moved standing on edge on a horizontal conveyor (1,2) past the nozzles (10,11) supplying the sealing mass. The rotatable nozzle (10) rotates infinitely during its up and down movement and can be fixed at any angular position. The rotatable nozzle can be brought into the work position of the other nozzle (11). The horizontal conveyor has a reversible drive. Only the metering device belonging to the rotatable nozzle has a regulator which regulates the amount of sealing mass emerging in dependence on the relative speed between nozzle and glass pane.

Description

Die Erfindung geht aus von einer Vorrichtung zu Füllen der Randfuge von Isolierglasscheiben mit den im Oberbegriff des Anspruchs 1 angegebenen Merkmalen. Eine solche Vorrichtung ist aus der DE-C-28 16 437 bekannt. Sie dient zum Versiegeln von rechteckigen Isolierglassscheiben. Zu diesem Zweck dient eine der beiden Düsen zum Füllen des unteren, dem Waagerechtförderer zugewandten Abschnittes der Randfuge, wohingegen die andere Düse zum Füllen der übrigen drei Abschnitte der Randfuge dient und zu diesem Zweck schrittweise um jeweils 90° drehbar ist. Die Menge der aus den Düsen austretenden Versiegelungsmasse wird bei konstanter Relativgeschwindigkeit zwischen Düse und Isolierglasscheibe in Abhängigkeit von der Breite und Tiefe der Randfuge gesteuert. Die bekannte Vorrichtung erlaubt hohe Arbeitsgeschwindigkeiten bzw. niedrige Taktzeiten.The invention is based on a device for filling the edge joint of insulating glass panes with those in the preamble of claim 1 specified features. Such Device is known from DE-C-28 16 437. she serves for sealing rectangular insulating glass panes. To for this purpose one of the two nozzles is used to fill the lower section facing the horizontal conveyor the edge joint, whereas the other nozzle for filling the remaining three sections of the edge joint serves and to this Purpose is rotatable step by step by 90 °. The amount the sealing compound emerging from the nozzles at constant relative speed between nozzle and Insulating glass pane depending on the width and Controlled depth of the edge joint. The known device allows high working speeds or low Cycle times.

Es gibt jedoch nicht nur rechteckige Isolierglasscheiben, sondern auch Isolierglasscheiben, deren Ümrißgestalt von der Rechteckform abweicht, z.3. Isolierglasscheiben mit gerundeten Ecken, dreieckige Isolierglasscheiben oder Isolierglasscheiben, die teilweise durch einen Kreisbogenabschnitt begrenzt sind. Solche Isolierglasscheiben werden auch als Modellscheiben bezeichnet. Modellscheiben können mit der bekannten Vorrichtung nicht versiegelt werden.However, there are not only rectangular insulating glass panes, but also insulating glass panes, the outline of which deviates from the rectangular shape, z.3. Insulating glass panes with rounded corners, triangular insulating glass panes or insulating glass panes partially through a circular arc section are limited. Such insulating glass panes are also called model discs. Model discs can be made with the known device not be sealed.

Modellscheiben werden heute entweder von Hand versiegelt, indem man sie auf einen waagerechten Drehtisch legt und mit einer von Hand geführten Düse unter Drehen der Isolierglasscheibe deren Rand abfährt. Zum automatischen Versiegeln von Modellscheiben sind Vorrichtungen bekannt, welche nur eine Düse haben und deren Bewegung relativ zur Isolierglasscheibe längs deren Randes numerisch gesteuert wird. Damit die Düse der Kontur der Isolierglasscheibe folgen kann, ist sie stufenlos drehbar (DE-A-40 09 441, DE-A-40 09 436, EP-B-391 884). Mit einer solchen Vorrichtung lassen sich auch rechteckige Isolierglasscheiben versiegeln, jedoch mit geringerer Taktzeit als im Fall einer Vorrichtung gemäss der DE-PS 28 16 437, so dass im Vergleich damit die Produktionsleistung einer Isolierfertigungslinie, in welcher die Versiegelungsvorrichtung steht, abfällt. Da derzeit der Anteil von Modellscheiben an der Isolierglasproduktion in der Regel nur zwischen 4 % und 10 % liegt, Rechteckformate also weit überwiegen, sind die bekannten, mit nur einer Düse arbeitenden Versiegelungsvorrichtungen ungünstig, wenn die Produktionsnachfrage hoch und die Isolierglasfertigungslinie ausgelastet ist.Today model windows are either sealed by hand, by placing them on a horizontal turntable and with a hand-guided nozzle while rotating the insulating glass pane the edge of which leaves. For automatic Devices for sealing model windows are known which have only one nozzle and their movement relative numerically controlled to the insulating glass pane along its edge becomes. So that the nozzle of the contour of the insulating glass pane can follow, it is continuously rotatable (DE-A-40 09 441, DE-A-40 09 436, EP-B-391 884). With such a device rectangular insulating glass panes can also be sealed, however with a shorter cycle time than in the case a device according to DE-PS 28 16 437, so that in comparison to the production output of an insulation production line, in which the sealing device stands, falls off. Since currently the share of Model panes on insulating glass production in the Usually only between 4% and 10%, rectangular formats so far predominate are the well-known, with only one Nozzle working sealing devices unfavorable, when the production demand is high and the insulating glass production line is busy.

In der DE 40 09 441 A1 ist die Möglichkeit angegeben, daß die Vorrichtung auch mit zwei Düsen ausgerüstet sein kann, jedoch ist nicht näher ausgeführt, wie die beiden Düsen angeordnet sind. Sind sie so angeordnet, wie in der DE 28 16 437 B1 offenbart, dann kann die obere, drehbare Düse nicht in die Arbeitsposition der anderen, unteren Düse gebracht werden. Dadurch ergibt sich für eine solche Vorrichtung das Problem, daß Modellscheiben mit beiden Düsen gefüllt werden müssen und dies zu dem in der DE 40 09 441 A1 offenbarten Nachteils eines erheblichen Steuerungsaufwandes führt, so daß die DE 40 09 441 A1 davon abrät, eine Vorrichtung mit zwei Düsen zum Versiegeln von Modellscheiben zu verwenden.DE 40 09 441 A1 specifies the possibility that the device can also be equipped with two nozzles, but is not detailed, how the two nozzles are arranged. Are they arranged as in DE 28 16 437 B1 discloses, then the upper, rotatable nozzle can not be brought into the working position of the other, lower nozzle. Thereby The problem arises for such a device that model discs must be filled with both nozzles and this to that in DE 40 09 441 A1 disclosed disadvantage of a significant control effort leads, so that DE 40 09 441 A1 advises against it, a device with two Use nozzles to seal model windows.

Manche Isolierglashersteller behelfen sich damit, dass sie neben einer oder mehreren Fertigungslinien mit einer Versiegelungsvorrichtung gemäss der DE-PS 28 16 437 noch eine Fertigungslinie für Modellscheiben haben, die mit einer Versiegelungsvorrichtung mit nur einer Düse arbeitet, die numerisch gesteuert ist. Nachteilig dabei ist, dass Aufträge eines Kunden, die sowohl rechteckige Isolierglasscheiben als auch Modellscheiben enthalten, nicht geschlossen auf einer Fertigungslinie gefertigt werden können. Die getrennte Fertigung erfordert einen kostenintensiven und zeitintensiven Aufwand für das nachträgliche Sortieren und Zusammenfassen der Isolierglasscheiben für den jeweiligen Auftrag und erhöht in unerwünschter Weise die Lieferzeiten.Some insulating glass manufacturers manage that next to one or more production lines with one Sealing device according to DE-PS 28 16 437 still have a production line for model discs, which with a sealing device works with only one nozzle, which is numerically controlled. A disadvantage here is that a customer's orders are both rectangular Contain insulating glass panes as well as model panes, not closed on a production line can be. The separate manufacturing requires one costly and time consuming effort for that subsequent sorting and summarizing of the insulating glass panes for the respective order and increased in the delivery times undesirably.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, einen Weg aufzuzeigen, wie rechteckige Isolierglasscheiben und Modellscheiben, die entsprechend dem Auftragseingang in wechselnder Folge zu fertigen sind, rationeller versiegelt und gefertigt werden können.The present invention is based on the object to show a way, like rectangular insulating glass panes and model discs that match the order intake are to be produced in alternating order, can be sealed and manufactured more efficiently.

Diese Aufgabe wird gelöst durch eine Vorrichtung mit den im Anspruch 1 angegebenen Merkmalen. Vorteilhafte Weiterbildungen der Erfindung sind Gegenstände der abhängigen Ansprüche.This object is achieved by a device with the features specified in claim 1. Advantageous further training the invention are subject of the dependent Expectations.

Die neue Versiegelungsvorrichtung hat wie die aus der DE-PS 28 16 437 bekannte Vorrichtung eine Düse, die mit nach oben weisender Öffnung in einer Lücke des Waagerechtförderers angeordnet und aus einer tieferliegenden unwirksamen Position in eine Arbeitsposition bewegbar ist, in welcher sie dem unteren Rand der Isolierglasscheibe anliegt; die neue Vorrichtung hat darüberhinaus eine stufenlos drehbare und in beliebigen Drehwinkelstellungen festlegbare Düse, welche in der Lücke zwischen den beiden Abschnitten des Waagerechtförderers und der darüber angeordneten Stützeinrichtung auf und ab bewegbar ist, wobei die Düse auch während ihrer Auf- und Abbewegung drehbar ist. Diese neue Vorrichtung hat zahlreiche Vorteile:

  • Die in großer Anzahl anfallenden rechteckigen Isolierglasscheiben können mit hoher Arbeitsgeschwindigkeit bzw. niedriger Taktzeit wie mit einer Vorrichtung gemäss der DE-PS 28 16 437 versiegelt werden.
  • Mit der neuen Vorrichtung können auch Modellscheiben versiegelt werden, soweit diese wenigstens einen geradlinigen Randabschnitt haben, mit welchem sie auf den Waagerechtförderer aufgestellt werden können.
  • Modellscheiben können wie gewohnt versiegelt werden, indem man mit der drehbaren Düse ihren gesamten Umfang abfährt. Zu diesem Zweck ist die andere Düse so tief absenkbar, dass in ihre Arbeitsposition die drehbare Düse hineingebracht werden kann. Der Antrieb des Waagerechtförderers ist dabei reversibel und erlaubt eine Arbeitsweise, bei welcher die Isolierglasscheibe zunächst über die in der Lücke des Waagerechtförderers stehende drehbare Düse hinweggefahren wird, ohne dass diese tätig wird; der Versiegelungsvorgang beginnt an der hinteren unteren Ecke der Isolierglasscheibe, in dem die drehbare Düse von der hinteren unteren Ecke ausgehend die obere Kontur der Isolierglasscheibe abfährt bis zur vorderen unteren Ecke, unter Zurückbewegen der Isolierglasscheibe mittels des reversiblen Antriebes des Waagerechtförderers; zum Schluß wird dann die Isolierglasscheibe mit ihrem unteren Rand wiederum vorwärts über die drehbare Düse hinwegbewegt und der untere Abschnitt der Randfuge gefüllt.
  • Es ist ein besonderer Vorteil der vorliegenden Erfindung, dass sie auch bei Modellscheiben eine höhere Arbeitsgeschwindigkeit erlaubt, indem Modellscheiben nicht nur mit der drehbaren, sondern mit beiden Düsen zugleich versiegelt werden, ähnlich der Arbeitsweise gemäss der DE-PS 28 16 437, wobei jedoch die drehbare Düse nicht lediglich 90°-Drehungen vollführt, sondern der Kontur der Modellscheibe angepaßt stufenlose Drehungen oder von 90° verschiedene Drehungen um spitzwinklige oder stumpfwinklige Ecken herum vollführt.
  • Modellscheiben und rechteckige Isolierglasscheiben können in beliebiger Reihenfolge bearbeitet werden.
  • Die neue Vorrichtung ist damit ausserordentlich flexibel und erreicht eine bisher nicht da gewesene Produktionsleistung.
  • Vorzugsweise hat mindestens die zur drehbaren Düse gehörende Dosiereinrichtung, am besten aber haben beide Dosiereinrichtungen einen eigenen Regler, der die Menge der austretenden Versiegelungsmasse abhängig von der Relativgeschwindigkeit zwischen der jeweiligen Düse und der Isolierglasscheibe regelt. Das erlaubt es, die Relativgeschwindigkeiten und den Durchsatz der Versiegelungsmasse durch die Düsen in optimalen Bereichen einzustellen und schwer kontrollierbare Extreme zu vermeiden. Zusätzlich kann natürlich, wie an sich bekannt, der Durchsatz der Versiegelungsmasse in Abhängigkeit von der Breite und Tiefe der Randfuge gesteuert werden, um sicherzustellen, dass diese gefüllt, aber nicht überfüllt wird.
The new sealing device, like the device known from DE-PS 28 16 437, has a nozzle which is arranged with an opening facing upwards in a gap in the horizontal conveyor and can be moved from a lower, ineffective position into a working position in which it is located at the lower edge of the Insulating glass pane rests; the new device also has an infinitely rotatable nozzle which can be fixed in any rotational angle positions and which can be moved up and down in the gap between the two sections of the horizontal conveyor and the support device arranged above it, the nozzle also being rotatable during its up and down movement. This new device has numerous advantages:
  • The large number of rectangular insulating glass panes can be sealed with a high working speed or a low cycle time as with a device according to DE-PS 28 16 437.
  • Model discs can also be sealed with the new device, provided that they have at least one straight edge section with which they can be placed on the horizontal conveyor.
  • Model windows can be sealed as usual by sweeping their entire circumference with the rotating nozzle. For this purpose, the other nozzle can be lowered so deep that the rotatable nozzle can be brought into its working position. The drive of the horizontal conveyor is reversible and allows a mode of operation in which the insulating glass pane is first moved over the rotating nozzle standing in the gap of the horizontal conveyor without this being active; the sealing process begins at the rear lower corner of the insulating glass pane, in which the rotatable nozzle starts from the lower rear corner and travels the upper contour of the insulating glass pane to the lower front corner, while moving the insulating glass pane back using the reversible drive of the horizontal conveyor; Finally, the lower edge of the insulating glass pane is again moved forward over the rotatable nozzle and the lower section of the edge joint is filled.
  • It is a particular advantage of the present invention that it also allows a higher working speed for model discs, in that model discs are sealed not only with the rotatable but also with both nozzles, similar to the method according to DE-PS 28 16 437, but with the rotatable nozzle does not only make 90 ° rotations, but continuously adjusts to the contour of the model disc or rotates from 90 ° around acute or obtuse corners.
  • Model panes and rectangular insulating glass panes can be processed in any order.
  • The new device is therefore extremely flexible and achieves an unprecedented production output.
  • At least the metering device belonging to the rotatable nozzle preferably has, but it is best if both metering devices have their own controller which regulates the amount of the sealing compound emerging as a function of the relative speed between the respective nozzle and the insulating glass pane. This makes it possible to set the relative speeds and the throughput of the sealing compound through the nozzles in optimal areas and to avoid extremes that are difficult to control. In addition, as is known per se, the throughput of the sealing compound can of course be controlled as a function of the width and depth of the edge joint in order to ensure that it is filled but not overfilled.

Bei dem Waagerechtförderer kann es sich um angetriebene Rollen oder um angetriebene Bänder (wie z.B. aus der DE-A-40 29 669 bekannt) oder um einen Kettenförderer, mit die Ränder der Isolierglasscheibe untergreifenden Auflagern und Gegenhaltern wie aus der DE-C-34 00 031 bekannt, handeln. Da es für die Zwecke der vorliegenden Erfindung darauf nicht entscheidend ankommt, ist die Art des Waagerechtförderers nicht detailliert dargestellt; dargestellt ist aber die Lage der Auflagefläche 8 des Waagerechtförderers, welche die Höhenlage des unteren Randes der Isolierglasscheibe 7 bestimmt.The horizontal conveyor can be driven Rolls or around driven belts (such as from the Known from DE-A-40 29 669) or a chain conveyor, with reaching under the edges of the insulating glass pane Support and counterhold as from DE-C-34 00 031 known to act. As it is for the purposes of the present Invention that does not matter is the Type of horizontal conveyor not shown in detail; but is shown the location of the bearing surface 8 of the Horizontal conveyor, which indicates the altitude of the lower one Edge of the insulating glass panel 7 determined.

Die zweite Düse 11 ist tiefer angeordnet als die erste Düse. Die zweite Düse 11 befindet sich unterhalb der drehbaren Düse 10 und hat eine Arbeitsposition (Figur 1), in welcher sie sich mit nach oben gerichteter Düsenöffnung in Höhe der Aufstellfläche 8 des Waagerechtförderers befindet und dem unteren Rand der Isolierglasscheibe 7 anliegt. Die zweite Düse 11 ist darüberhinaus mitsamt ihrem Träger 13 in eine unwirksame Position (Figur 2) absenkbar.The second nozzle 11 is arranged lower than the first Jet. The second nozzle 11 is located below the rotatable nozzle 10 and has a working position (Figure 1), in which they are with the nozzle opening facing upwards at the level of the footprint 8 of the horizontal conveyor and abuts the lower edge of the insulating glass pane 7. The second nozzle 11 is also complete its carrier 13 in an ineffective position (Figure 2) can be lowered.

Zu jeder Düse gehört eine Dosiereinrichtung, welche hinter den Waagerechtförderern 1 und 2 bzw. den Stützwänden 5 und 6 angeordnet ist und von welchen bewegliche Leitungen zu den Düsen 10 und 11 führen.Each nozzle has a metering device, which is behind the horizontal conveyors 1 and 2 or the supporting walls 5 and 6 is arranged and from which movable lines to guide the nozzles 10 and 11.

Zum Versiegeln von rechteckigen Isolierglasscheiben 7 arbeitet die Vorrichtung in entsprechender Weise wie die in der DE-PS 28 16 437 beschriebene Vorrichtung (Figur 1): In Ausgangslage ist die Düse 11 abgesenkt und die Düse 10 befindet sich in Höhe der Aufstellfläche 8, wobei die Düsenöffnung der Förderrichtung 14 entgegengerichtet ist (gegenüber der Darstellung in Figur 1 um 90° im Uhrzeigersinn verdreht). Die Isolierglasscheibe 7 wird in Förderrichtung 14 herangefördert, bis sie mit ihrem vorderen Rand 7a an die Düse 10 stößt und stehen bleibt. Bei stehender Isolierglasscheibe 7 fährt die Düse am vorderen Rand 7a hoch und wird entgegen dem Uhrzeigersinn um 90° verschwenkt, wenn die Düsenöffnung die vordere obere Ecke der Isolierglasscheibe 7 erreicht. In der Zwischenzeit wird die zweite Düse 11 hochgefahren, bis sie dem unteren Rand 7d der Isolierglasscheibe anliegt. Die Isolierglasscheibe wird nun vom Waagerechtförderer 1, 2 in Richtung des Pfeils 14 weiterbewegt, wobei die Abschnitte der Randfuge am oberen Rand 7b und am unteren Rand 7d gefüllt werden. Wenn die Isolierglasscheibe 7 mit ihren hinteren Ecken in den Bereich der Düsenöffnungen gelangt, wird sie gestoppt, die Düse 11 abgesenkt, die Düse 10 um 90° entgegen dem Uhrzeigersinn verschwenkt und am hinteren Rand 7c abwärtsbewegt, um den dort liegenden Abschnitt der Randfuge zu füllen. Erreicht die Düse 10 die hintere, untere Ecke, wird der Versiegelungsvorgang beendet, die Isolierglasscheibe 7 in Richtung des Pfeils 14 abgefördert und die Düse 10 um 180° gedreht, wodurch sie für einen neuen Versiegelungszyklus bereit ist.For sealing rectangular insulating glass panes 7 the device operates in a manner corresponding to that Device described in DE-PS 28 16 437 (Figure 1): In the starting position, the nozzle 11 is lowered and the nozzle 10 is at the level of the footprint 8, the Nozzle opening of the conveying direction 14 is opposite (Compared to the representation in Figure 1 by 90 ° clockwise twisted). The insulating glass pane 7 is in the conveying direction 14 advanced until it with its front edge 7a hits the nozzle 10 and stops. When standing Insulating glass pane 7 moves the nozzle on the front edge 7a up and is swiveled counter-clockwise by 90 °, if the nozzle opening is the front upper corner of the insulating glass pane 7 reached. In the meantime, the second nozzle 11 raised until it the lower edge 7d the insulating glass pane is in contact. The insulating glass pane will now from the horizontal conveyor 1, 2 in the direction of arrow 14 moved further, with the sections of the edge joint at the top Edge 7b and 7d at the bottom. If the Insulating glass pane 7 with its rear corners in the area of the nozzle openings, it is stopped Nozzle 11 lowered, nozzle 10 counter-clockwise by 90 ° pivoted and moved down at the rear edge 7c, around the section of the edge joint lying there to fill. If the nozzle 10 reaches the lower rear corner, the sealing process is ended, the insulating glass pane 7 conveyed in the direction of arrow 14 and the Nozzle 10 rotated 180 °, causing it to start a new sealing cycle ready.

Beim Versiegeln von Modellscheiben kann die Vorrichtung arbeiten, wie in Figur 2 am Beispiel einer dreieckigen Modellscheibe 15 dargestellt: Die Düse 11 befindet sich in ihrer unwirksamen, abgesenkten Stellung, die Versiegelung erfolgt lediglich mit der oberen, drehbaren Düse 10, welche sich zunächst mit nach oben weisender Düsenöffnung etwas unterhalb der Arbeitsposition der Düse 11 befindet. Die Isolierglasscheibe 15 wird in Richtung des Pfeiles 14 zunächst über die Düse 19 hinwegbewegt, bis ihre hintere Ecke im Bereich der Düsenöffnung stoppt. Die Düse 10 wird dann durch Anheben und Drehen im Uhrzeigersinn an den hinteren, schräg verlaufenden Rand 15b der Isolierglasscheibe angelegt. Danach wird die Isolierglasscheibe 15 entgegen der Richtung des Pfeiles 14 bewegt und gleichzeitig die Düse 10 mit einer der Neigung des Randes 15b angepaßten Geschwindigkeit angehoben, so dass die Düse 10 am Rand 10b entlang aufwärts gleitet bis zur oberen Ecke der Isolierglasscheibe. Wird diese erreicht, wird die Isolierglasscheibe 15 kurz angehalten, die Düse 10 im Uhrzeigersinn verdreht, bis sie dem schrägen vorderen Rand 15 der Isolierglasscheibe anliegt. Danach wird die Isolierglasscheibe 15 erneut entgegen der Richtung des Pfeils 14 bewegt und gleichzeitig die Düse 11 abwärts bewegt, so dass sie am vorderen Rand 15a abwärts gleitet, bis sie die vordere, untere Ecke erreicht. Dann wird die Isolierglasscheibe 15 gestoppt, die Düse 10 im Uhrzeigersinn gedreht, bis sie dem unteren Rand 15c anliegt. Dann wird die Isolierglasscheibe 15 in Richtung des Pfeiles 14 abgefördert und dabei im Durchlauf der untere Rand 15c versiegelt. Danach ist die Düse 10 bereit für einen neuen Versiegelungszyklus.The device can be used when sealing model windows work, as in Figure 2 using the example of a triangular Model disc 15 shown: The nozzle 11 is located in its ineffective, lowered position, the seal only with the upper, rotatable Nozzle 10, which initially faces upwards Nozzle opening slightly below the working position of the Nozzle 11 is located. The insulating glass pane 15 is in the direction arrow 14 first moves over nozzle 19, until their back corner in the area of the nozzle opening stops. The nozzle 10 is then raised and turned clockwise on the rear, sloping ones Edge 15b of the insulating glass pane created. After that the Insulating glass pane 15 against the direction of the arrow 14 moves and at the same time the nozzle 10 with one of the Incline of the edge 15b adjusted speed increased so that the nozzle 10 along the edge 10b upwards slides to the upper corner of the insulating glass pane. If this is achieved, the insulating glass pane 15 becomes short stopped, the nozzle 10 turned clockwise, until the inclined front edge 15 the insulating glass pane is in contact. Then the insulating glass pane 15 again against the direction of the arrow 14 moves and at the same time moves the nozzle 11 downwards, so that it slides down at the front edge 15a until it reaches the lower front corner. Then the Insulating glass pane 15 stopped, the nozzle 10 clockwise rotated until it abuts the lower edge 15c. Then the insulating glass pane 15 in the direction of the arrow 14 conveyed and the bottom edge in the run 15c sealed. Then the nozzle 10 is ready for you new sealing cycle.

Zum Versiegeln von Modellscheiben kann die Vorrichtung aber auch so arbeiten, wie anhand einer halbrunden Isolierglasscheibe 16 in Figur 3 dargestellt: Am Beginn des Versiegelungsvorganges liegen dieselben Verhältnisse vor, wie im Beispiel gemäss Figur 1. Bei.zunächst ruhender Isolierglasscheibe 16 fährt die Düse 10 am vorderen Rand 16a der Isolierglasscheibe hoch; sobald sie in den gekrümmten Bereich 16b des Randes eintritt, wird der Antrieb des Waagerechtförderers 1,2 gestartet und die Isolierglasscheibe in Richtung des Pfeils 14 vorwärtsbewegt, so dass der gekrümmte Bereich 16b und der untere Rand 16d der Isolierglasscheibe gemeinsam im Durchlauf versiegelt werden. Gelangt die hintere untere Ecke der Isolierglasscheibe in den Bereich der Öffnung der Düse 11, wird diese geschlossen und abgesenkt sowie der Vorschub des Waagerechtförderers stillgesetzt und die Düse 10, welche sich bei ihrer Bewegung entlang des gekrümmten Randes 16b stufenlos drehte, bleibt in der nun eingenommenen Stellung, in Richtung des Pfeils 14 blickend, ausgerichtet und fährt am hinteren Rand 16c abwärts bis zur hinteren unteren Ecke. Das Dosieren der Dichtmasse, welche aus den Düsen austritt, erfolgt in Abhängigkeit von der Geschwindigkeit, mit welcher sich die jeweilige Düse am Rand der Isolierglasscheibe entlangbewegt. Die Relativgeschwindigkeit für die untere Düse 11 ist die Fördergeschwindigkeit des Waagerechtförderers. Die Relativgeschwindigkeit für die obere, drehbare Düse kann aus der Fördergeschwindigkeit des Waagerechtförderers und aus der aufwärtsgerichteten bzw. abwärtsgerichteten Geschwindigkeit der Düse 10 rechnerisch, z.B. mit Hilfe eines Mikrorechners, ermittelt werden.The device can be used to seal model windows but also work as if using a semicircular insulating glass pane 16 shown in Figure 3: At the beginning of Sealing process are the same conditions before, as in the example according to FIG. 1 Insulating glass pane 16 moves the nozzle 10 at the front edge 16a of the insulating glass pane high; once they're in the curved Area 16b of the edge enters the drive of the horizontal conveyor 1.2 started and the insulating glass pane moved in the direction of arrow 14 so that the curved region 16b and the lower edge 16d of the Insulating glass pane are sealed together in one pass. Get to the lower back corner of the insulating glass pane in the area of the opening of the nozzle 11, this is closed and lowered as well as the feed of the horizontal conveyor stopped and the nozzle 10, which at their movement along the curved edge 16b continuously rotated, remains in the position it now occupies, looking in the direction of arrow 14, aligned and driving at the rear edge 16c down to the lower rear Corner. Dosing the sealant, which comes from the nozzles emerges depending on the speed, with which the respective nozzle on the edge of the insulating glass pane moved along. The relative speed for the lower nozzle 11 is the conveying speed of the horizontal conveyor. The relative speed for the top, rotatable nozzle can from the conveying speed of the horizontal conveyor and from the upward or downward direction Arithmetic speed of nozzle 10, e.g. with the help of a microcomputer.
