Abstract

The device for heating the edges of glass panes, to which prefabricated spacing elements are to be attached, comprises a lateral support (1) for the glass panes, and a linear conveyor (2) which is provided at the bottom edge of the support (1) and is formed, for example, by a row of conveying rollers (3). Also provided are two horizontally aligned, elongate heating elements (5, 6) which are assigned to the horizontal edges of the glass pane. Of the said heating elements (5, 6), one (5) is arranged so as to be moveable up and down immediately above the linear conveyor (2) and the other (6) to be moveable up and down along the lateral support (1) (arrow 18). The two horizontal heating elements (5, 6) are fixed to carriers (7, 8) which can be swivelled about horizontal axes (9, 10), so that the heating elements (5, 6) can be swivelled out of their active position associated with the glass pane. Finally, an elongate (5), essentially vertically aligned heating device (14) is provided, which is arranged next to the vertical edge (13) on the outlet side of the lateral support (1) and has two mutually facing heating elements (15, 16). <IMAGE>

Description

Die Erfindung betrifft eine Vorrichtung zum Anwärmen des Randbereiches von Glastafeln, auf die vorgefertigte Ab­standhalter anzusetzen sind, mit einer seitlichen Abstüt­zung für die Glastafeln, mit einem am unteren Rand der Abstützung orgesehen Linearförderer, der beispielsweise aus einer Reihe von Förderrollen besteht, mit zwei hori­zontal ausgerichteten, den horizontalen Randbereichen der Glastafeln zugeordneten, langgestreckten Heizelementen, wobei das eine der horizontal ausgerichteten Heizelemente unmittelbar oberhalb des Linearförderers angeordnet ist und das andere der horizontal ausgerichteten Heizelemente entlang der seitlichen Abstützung auf- und abbewegbar ist, und mit einer langgestreckten, im wesentlichen ver­tikal ausgerichteten Heizvorrichtung.The invention relates to a device for heating the edge region of glass sheets on which prefabricated spacers are to be attached, with a lateral support for the glass sheets, with a linear conveyor provided at the lower edge of the support, which consists, for example, of a series of conveyor rollers, with two horizontally aligned , assigned to the horizontal edge regions of the glass panels, elongated heating elements, one of the horizontally oriented heating elements being arranged directly above the linear conveyor and the other of the horizontally oriented heating elements being movable up and down along the lateral support, and with an elongated, essentially vertically oriented Heater.

Das Ansetzen von vorgefertigten Abstandhaltern auf Glas­tafeln im Zuge der Herstellung von Isolierglasscheiben erfordert eine Mindesttemperatur der Glastafel und/oder des Abstandhalters, damit fester Halt des vorgefertigten flexiblen Abstandhalters (swiggle strip) an der Glastafel erzielt wird. Die Erwärmung von vorgefertigten Abstand­haltern, wie sie beispielsweise aus der DE-OS 30 02 904 bekannt sind, ist nicht ohne weiteres möglich, bzw. nur im begrenzten Ausmaß durchführbar, da diese an den in den Ansetzwerkzeugen vorgesehenen Führungs- und Umlenkrollen anhaften würden. Eine Vorrichtung zum Ansetzen von swig­gle-strips ist z.B. aus der DE-OS 3 310 441 bekannt.The placement of prefabricated spacers on glass panels in the course of the production of insulating glass panes requires a minimum temperature of the glass panel and / or the spacer so that the prefabricated flexible spacer (swiggle strip) is firmly held on the glass panel. The heating of prefabricated spacers, such as are known for example from DE-OS 30 02 904, is not readily possible, or can only be carried out to a limited extent, since these would adhere to the guide and deflection rollers provided in the attachment tools. A device for attaching swiggle strips is e.g. known from DE-OS 3 310 441.

Anderseits ist es wenig sinnvoll, eine Glastafel, auf die ein derartiger, vorgefertigter Abstandhalter angesetzt werden soll, in ihrer Gesamtheit zu erwärmen.On the other hand, it makes little sense to heat a glass sheet as a whole on which such a prefabricated spacer is to be attached.

Aus der EP-B- 061 183 ist eine Vorrichtung bekannt, mit der die Randbereiche von Isolierglasscheiben erwärmt wer­den können, um den Kleber, mit dem ein zwischen die Glas­ tafeln der Isolierglasscheibe eingefügte Abstandhalter­rahmen beschichtet ist, durch Wärmezufuhr zu aktivieren, um eine Verklebung zwischen dem Abstandhalter und den beiden Glastafeln zu erzielen.From EP-B-061 183 a device is known with which the edge areas of insulating glass panes can be heated to the adhesive with which one between the glass panels of the insulating glass pane inserted spacer frame is coated by heat to activate to achieve a bond between the spacer and the two glass panels.

Die Heizelemente der aus der EP-A-061 183 bekannten Vor­richtung sind ausschließlich parallel zur Ebene der im Randbereich anzuwärmenden Glastafeln beweglich angeord­net. Eine Anregung, die horizontalen Heizelemente an aus­schwenkbaren Halterungen vorzusehen, ist der EP-A-061 183 nicht zu entnehmen.The heating elements of the device known from EP-A-061 183 are arranged to be movable only parallel to the plane of the glass panels to be heated in the edge region. EP-A-061 183 does not provide any suggestion to provide the horizontal heating elements on pivotable holders.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrich­tung der eingangs genannten Gattung anzugeben, die ein­fach aufgebaut und mit welcher der Randbereich einer Glastafel vor dem Ansetzen eines vorgefertigten Abstand­halters (swiggle-strip) rasch angewärmt werden kann. Wei­ters soll die erfindungsgemäße Vorrichtung problemlos in eine Linie zur Herstellung von Isolierglas integriert werden können.The invention has for its object to provide a device of the type mentioned, which is simple in construction and with which the edge region of a glass sheet can be quickly warmed before the attachment of a prefabricated spacer (swiggle-strip). Furthermore, the device according to the invention should be able to be easily integrated into a line for the production of insulating glass.

Erfindungsgemäß wird diese Aufgabe bei einer Vorrichtung der eingangs genannten Gattung dadurch gelöst, daß die horizontalen Heizelemente an Trägern befestigt sind, die um horizontale Achsen verschwenkbar sind, so daß die Heizelemente aus ihrer der Glastafel zugeordneten Wirk­lage ausschwenkbar sind, und daß die vertikal ausgerich­tete Heizvorrichtung neben dem auslaufseitigen vertikalen Rand der seitlichen Abstützung vorgesehen ist und vor­zugsweise zwei einander zugekehrte Heizelemente aufweist.According to the invention, this object is achieved in a device of the type mentioned in the introduction in that the horizontal heating elements are fastened to supports which can be pivoted about horizontal axes, so that the heating elements can be swung out of their operative position assigned to the glass sheet, and in that the vertically oriented heating device is adjacent the vertical edge of the lateral support on the outlet side is provided and preferably has two heating elements facing each other.

Mit der erfindungsgemäßen Vorrichtung, die in Anlagen zur Herstellung von Isolierglas, in welchen die Glastafeln horizontal oder bevorzugt vertikal ausgerichtet befördert und bearbeitet werden, problemlos integriert werden kann, können die Randbereiche der Glastafeln rasch auf die ge­wünschte Temperatur aufgeheizt werden.With the device according to the invention, which can be easily integrated into systems for the production of insulating glass, in which the glass sheets are conveyed and processed horizontally or preferably aligned vertically, the edge regions of the glass sheets can be quickly heated to the desired temperature.

Da die horizontalen Heizelemente aus ihrer der Glastafel zugeordneten Wirklage ausschwenkbar sind, und da die ver­tikal ausgerichtete Heizvorrichtung neben dem auslaufsei­tigen vertikalen Rand der seitlichen Abstützung vorgese­hen ist, können die Heizelemente ständig auf Temperatur gehalten werden, wenn die Vorrichtung in Betrieb ist, oh­ne daß sich die übrigen Teile der Vorrichtung übermäßig erwärmen, so daß die Heizelemente nach dem Heranfördern einer Glastafel in die Vorrichtung nicht erst aufgeheizt werden müssen. Auf diese Weise ist eine sehr kurze Takt­zeit möglich.Since the horizontal heating elements can be swung out of their operative position assigned to the glass sheet, and since the vertically oriented heating device is provided next to the vertical edge of the lateral support on the outlet side, the heating elements can be kept constantly at temperature when the device is in operation without the heat the remaining parts of the device excessively, so that the heating elements do not have to be heated up after moving a glass sheet into the device. A very short cycle time is possible in this way.

Weitere Einzelheiten und Merkmale der Erfindung ergeben sich aus den Unteransprüchen und der nachstehenden Be­schreibung, des in der Zeichnung schematisch wiedergege­benen Ausführungsbeispieles. Es zeigt Fig. 1 eine Vor­richtung zum Anwärmen des Randbereiches von Glastafeln in Ansicht von vorne und Fig. 2 einen Schnitt längs der Li­nie II-II in Fig. 1.Further details and features of the invention emerge from the subclaims and the following description of the exemplary embodiment shown schematically in the drawing. 1 shows a device for heating the edge region of glass sheets in a view from the front and FIG. 2 shows a section along the line II-II in FIG. 1.

Die in Fig. 1 gezeigte Vorrichtung besitzt eine seitliche Abstützung 1 für die zu behandelnden Glastafeln, die wie in modernen Isolierglasherstellungsanlagen üblich, um we­nige Grad nach hinten geneigt transportiert wird. Die Glastafeln liegen an der seitlichen Abstützung 1, bei­spielsweise über nicht gezeigte, um parallel zur Ebene der seitlichen Abstützung 1 ausgerichtete, d.h. im we­sentlichen vertikale Achsen frei drehbare Stützrollen ab. Am unteren Rand der seitlichen Abstützung 1 ist ein Line­arförderer 2 vorgesehen, der im gezeigten Ausführungsbei­spiel durch eine Reihe von Förderrollen 3, deren Achsen senkrecht zur Ebene der seitlichen Abstützung 1 ausge­richtet sind, gebildet. Aus Fig. 1 ist noch ersichtlich, daß zwischen den einzelnen Förderrollen 3 des Linearför­derers 2 Abdeckbleche 4 vorgesehen sind, zwischen denen die Förderrollen 3 geringfügig nach oben vorstehen.The device shown in FIG. 1 has a lateral support 1 for the glass panels to be treated, which is transported, as is customary in modern insulating glass production plants, inclined a few degrees to the rear. The glass panels lie on the lateral support 1, for example via not shown, which is oriented parallel to the plane of the lateral support 1, i.e. essentially vertical axes from freely rotatable support rollers. At the lower edge of the lateral support 1, a linear conveyor 2 is provided, which in the exemplary embodiment shown is formed by a series of conveyor rollers 3, the axes of which are oriented perpendicular to the plane of the lateral support 1. From Fig. 1 it can also be seen that between the individual conveyor rollers 3 of the linear conveyor 2 cover plates 4 are provided, between which the conveyor rollers 3 protrude slightly upwards.

In der Vorrichtung sind zwei horizontal ausgerichtete, langgestreckte Heizelemente 5 und 6 vorgesehen. Die Heiz­elemente 5 und 6 sind an Trägern 7 und 8 befestigt, die um im wesentlichen horizontale Achsen 9 bzw. 10 mit Hilfe von Druckmittelmotoren 11 verschwenkbar sind. Auf diese Weise können die Heizelemente 5 und 6 aus ihrer in Fig. 1 gezeigten Wirklage in der sie dem unteren horizontalen Randbereich (Heizelement 5) bzw. dem oberen horizontalen Randbereich (Heizelement 6) einer Glastafel zugeordnet sind, in eine Nicht-Wirklage (Fig. 2) ausgeschwenkt wer­den. Es ist daher die seitliche Abstützung 1 und der Li­nearförderer 2 der Wärmeabstrahlung der Heizelemente 5 und 6 nicht ausgesetzt, wenn in der Vorrichtung gerade keine Glastafel angewärmt wird.In the device there are two horizontally aligned elongated heating elements 5 and 6 are provided. The heating elements 5 and 6 are fastened to supports 7 and 8 which can be pivoted about essentially horizontal axes 9 and 10 with the aid of pressure medium motors 11. In this way, the heating elements 5 and 6 can be moved from their operative position shown in FIG. 1, in which they are assigned to the lower horizontal edge area (heating element 5) or the upper horizontal edge area (heating element 6) of a glass sheet, into a non-active position (FIG 2) can be swung out. The lateral support 1 and the linear conveyor 2 are therefore not exposed to the heat radiation of the heating elements 5 and 6 when no glass sheet is being heated in the device.

Neben dem, bezogen auf die Förderrichtung (Pfeil 12) hin­teren, vertikalen Rand 13 der seitlichen Abstützung 1 ist eine Heizvorrichtung 14 vorgesehen, die aus zwei einander zugekehrten Heizelementen 15 und 16 (Fig. 2) besteht. Zwischen den beiden Heizelementen 15 und 16 der Heizvor­richtung 14 ist ein Spalt freigelassen, durch den sich eine Glastafel bewegt. Die Heizvorrichtung 14 dient zum Anwärmen der im wesentlichen vertikalen Abschnitte der Randbereiche der Glastafel.In addition to the vertical edge 13 of the lateral support 1, which is at the rear in relation to the conveying direction (arrow 12), a heating device 14 is provided, which consists of two heating elements 15 and 16 (FIG. 2) facing each other. A gap is left between the two heating elements 15 and 16 of the heating device 14, through which a glass sheet moves. The heating device 14 serves to heat the substantially vertical sections of the edge regions of the glass sheet.

Um das obere der beiden horizontal ausgerichteten lang­gestreckten Heizelemente 5 und 6, d.h. das Heizelement 6 gegenüber dem oberen, horizontalen Abschnitt des Randbe­reiches einer Glastafel ausrichten zu können, ist dessen Träger 8 im Maschinengestell 17 bzw. auf mit diesem ver­bundenen Führungsschienen auf- und abverschiebbar (Pfeile 18) geführten Schlitten 19 und 20 gelagert. Die Schlitten 19 und 20 des Heizelementes 6 werden von einer Steuerung, der ein der Höhe der im Randbereich anzuwärmenden Glas­tafel entsprechendes Signal zugeführt wird, durch ihre Antriebe vertikal so ausgerichtet, daß das obere Heiz­element 6 dem oberen Abschnitt des Randbereiches einer Glastafel gegenüberliegend ausgerichtet ist, wenn es in seine Wirklage eingeschwenkt worden ist.In order to be able to align the upper of the two horizontally oriented elongate heating elements 5 and 6, ie the heating element 6 with respect to the upper, horizontal section of the edge region of a glass sheet, its support 8 can be moved up and down in the machine frame 17 or on guide rails connected to it ( Arrows 18) guided carriage 19 and 20 stored. The slides 19 and 20 of the heating element 6 are vertically aligned by a control, which is supplied with a signal corresponding to the height of the glass sheet to be heated in the edge area, by their drives such that the upper heating element 6 is aligned opposite the upper section of the edge area of a glass sheet, when it has been swung into its operative position.

Zur Betätigung der Schlitten 19 und 20 können über Um­lenkrollen 21 geführte Seilzüge od.dgl. vorgesehen sein.To operate the sled 19 and 20 21 cables or the like guided over pulleys. be provided.

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

Eine Glastafel wird an der seitlichen Abstützung 1 an­liegend, vom Linearförderer 2 in die Vorrichtung geför­dert und in ihr soweit transportiert, bis der bezogen auf die Förderrichtung (Pfeil 12) vordere, im wesentlichen vertikal ausgerichtete Rand der Glastafel zwischen den Heizelementen 15 und 16 der Heizvorrichtung 14 angeordnet ist. Während des Förderns der Glastafel wird das obere horizontale Heizelement 6 entsprechend der Höhe der Glas­tafel ausgerichtet und die Heizelemente 5 und 6 werden, sobald die Glastafel, wie oben beschrieben, ausgerichtet worden ist, durch Betätigung der Druckmittelmotore 11 in ihre Wirklagen eingeschwenkt. Sobald der vordere, verti­kal ausgerichtete und die beiden horizontal ausgerichte­ten Abschnitte des Randbereiches der Glastafel hinrei­chend erwärmt worden ist, wird die Glastafel weiterbe­fördert, bis sich ihr, bezogen auf die Förderrichtung (Pfeil 12) hinterer Randbereich im Bereich der Heiz­vorrichtung 14 befindet. Während dieser Bewegung der Glastafel oder danach werden die horizontal ausgerich­teten Heizelemente 5 und 6 aus ihren Wirklagen ausge­schwenkt. Nachdem nun auch der hintere Randbereich der Glastafel angewärmt worden ist, wird diese vorzugsweise unmittelbar einer Vorrichtung zum Ansetzen eines Ab­standhalters (swiggle-strip) zugeführt.A glass sheet is in contact with the lateral support 1, conveyed into the device by the linear conveyor 2 and transported therein until the essentially vertically oriented front edge of the glass sheet between the heating elements 15 and 16 of the heating device in relation to the conveying direction (arrow 12) 14 is arranged. While the glass sheet is being conveyed, the upper horizontal heating element 6 is aligned in accordance with the height of the glass sheet and the heating elements 5 and 6, as soon as the glass sheet has been aligned as described above, are pivoted into their operative positions by actuating the pressure medium motors 11. As soon as the front, vertically aligned and the two horizontally aligned sections of the edge area of the glass sheet have been sufficiently heated, the glass sheet is conveyed on until it is located in the area of the heating device 14 in relation to the conveying direction (arrow 12). During this movement of the glass sheet or thereafter, the horizontally oriented heating elements 5 and 6 are pivoted out of their operative positions. Now that the rear edge area of the glass sheet has also been heated, it is preferably fed directly to a device for attaching a spacer (swiggle-strip).
