Description

Die Erfindung betrifft eine Vorrichtung zum Fördern von Isolierglasscheiben, die drei zueinander parallele Glasplatten haben, nämlich eine vordere Glasplatte, eine hintere Glasplatte und eine mittlere Glasplatte, welche entlang ihrer Ränder durch einen klebenden ersten Abstandhalter und durch einen klebenden zweiten Abstandhalter paarweise auf Abstand voneinander gehalten und miteinander verklebt sind.The invention relates to a device for conveying insulating glass panes, which have three glass plates parallel to each other, namely a front glass plate, a rear glass plate and a central glass plate, which are spaced apart along their edges by an adhesive first spacer and by an adhesive second spacer and glued together.

Bekannt ist eine Vorrichtung zum Fördern von Isolierglasscheiben mit einem Gestell, mit einem vorderen Waagerechtförderer und mit einem hinteren Waagerechtförderer, welche mit veränderbarem Abstand voneinander nebeneinander an dem Gestell angebracht sind, und mit einer um einige Grad gegen die Vertikale nach hinten geneigten Stützeinrichtung zum Abstützen der Isolierglasscheiben, welche mit ihrer hinteren Glasplatte auf dem hinteren Waagerechtförderer und mit ihrer vorderen Glasplatte auf dem vorderen Waagerechtförderer stehen und gegen die Stützeinrichtung gelehnt sind, wobei die Stützeinrichtung eine Scheibenlaufebene definiert, in welcher die Außenseite der hinteren Glasplatte liegt.Disclosed is a device for conveying insulating glass panes with a frame, with a front horizontal conveyor and with a rear horizontal conveyor, which are mounted at a variable distance from each other side by side on the frame, and with a by a few degrees against the vertical backwards inclined support means for supporting the Insulated glass panes, which stand with their rear glass plate on the rear horizontal conveyor and with their front glass plate on the front horizontal conveyor and leaning against the support means are, wherein the support means defines a disc running plane, in which lies the outside of the rear glass plate.

Eine solche Vorrichtung ist aus der DE 199 09 638 C2 bekannt. Sie hat zwei Waagerechtförderer mit jeweils einem endlosen Zahnriemen, dessen Obertrum unterstützt ist. Eine Zweifach-Isolierglasscheibe wird mit ihrer vorderen Glasplatte auf den Zahnriemen des vorderen Waagerechtförderers und mit ihrer hinteren Glasplatte auf den Zahnriemen des hinteren Waagerechtförderers gestellt und gegen eine als Luftkissenwand ausgebildete Stützeinrichtung gelehnt, welche die Lage der Scheibenlaufebene bestimmt.Such a device is from the DE 199 09 638 C2 known. It has two horizontal conveyors each with an endless toothed belt whose upper run is supported. A double insulating glass pane is placed with its front glass plate on the toothed belt of the front horizontal conveyor and with its rear glass plate on the toothed belt of the rear horizontal conveyor and leaning against a formed as an air cushion wall support means which determines the position of the pane running plane.

Eine andere Vorrichtung mit diesen Merkmalen ist aus der DE 30 38 425 C2 bekannt. In diesem Fall weisen die beiden Waagerechtförderer synchron umlaufende endlose Ketten auf, an welchen L-förmige Auflager angebracht sind, auf welche die vordere Glasplatte und die hintere Glasplatte einer Isolierglasscheibe aufgestellt werden können. Die Isolierglasscheibe wird in der Nähe ihres oberen Randes an eine Zeile von freilaufenden Stützrollen gelehnt, welche an einem waagerechten Balken gelagert sind, welcher am Gestell der Fördervorrichtung angebracht und in der Höhe verstellbar ist. Die Stützrollen sind bewegliche Mittel zum Unterstützen der mittleren Glasplatte der Isolierglasscheiben, welche mittelbar am Gestell angebracht sind. Sie liegen dem nach unten weisenden Rand der mittleren Glasplatte an und werden beim Fördern der Isolierglasscheibe von dieser in Drehung versetzt. Bei diesem Stand der Technik definieren die L-förmigen Auflager des hinteren Waagerechtförderers und die Stützrollenzeile gemeinsam eine Scheibenlaufebene. Um mit einer Vorrichtung gemäß der DE 30 38 425 C2 Isolierglasscheiben fördern zu können, die drei zueinander parallele Glasplatten haben, ist es bekannt, zwischen den hinteren Waagerechtförderer und den vorderen Waagerechtförderer von Hand Leisten mit Stützrollen einzusetzen, wobei die Höhe der Stützrollen so gewählt ist, dass ihre Oberseite in der Flucht der Oberseite der waagerechten Schenkel der L-förmigen Auflager liegt, so dass die Stützrollen die mittlere Glasplatte einer Dreifach-Isolierglasscheibe unterstützen können. Dabei ist darauf zu achten, dass die Stützrollen genau auf die Lage der mittleren Glasplatte ausgerichtet und so schmal sind, dass sie nicht in den Bereich der beiden Randfugen der Dreifach-Isolierglasscheibe ragen, denn diese Randfugen werden mit einer zäh-klebrigen Versiegelungsmasse gefüllt, die an falsch ausgerichteten Stützrollen kleben bleiben kann, was nicht nur zu einer Verschmutzung der Isolierglasscheiben führen könnte, sondern auch die Abdichtung der Isolierglasscheiben beeinträchtigen würde. Es ist deshalb bekannt, für alle möglichen unterschiedlichen Lagen, welche die mittlere Glasplatte von Isolierglasscheiben in der Fördervorrichtung einnehmen kann, daran angepasste unterschiedliche Rollenleisten vorzuhalten, die jedes Mal dann von Hand gewechselt werden müssen, wenn eine Isolierglasscheibe mit geänderter Lage der mittleren Glasplatte kommt, und die jedes Mal von Hand entfernt werden müssen, wenn anstelle einer Dreifach-Isolierglasscheibe eine Zweifach-Isolierglasscheibe kommt. Das ist zeitraubend, vermindert die Leistungsfähigkeit einer Isolierglas-Fertigungslinie, von welcher die Vorrichtung zum Fördern von Isolierglasscheiben ein Bestandteil ist, und verteuert die Isolierglasfertigung. So kann es sein, dass für eine Isolierglasfertigungslinie Personal für eine zweite Schicht eingestellt werden muss, wenn der Anteil von Dreifach-Isolierglasscheiben an der Produktion von Isolierglasscheiben zu Lasten des Anteils von Zweifach-Isolierglasscheiben steigt.Another device with these features is known from DE 30 38 425 C2 known. In this case, the two horizontal conveyors have synchronously circulating endless chains, on which L-shaped supports are mounted, on which the front glass plate and the rear glass plate of an insulating glass pane can be placed. The insulating glass is leaned near its upper edge to a row of free-running support rollers which are mounted on a horizontal bar, which is mounted on the frame of the conveyor and adjustable in height. The support rollers are movable means for supporting the central glass plate of the insulating glass panes, which are indirectly mounted on the frame. They lie against the edge of the middle glass plate pointing downwards and are set in rotation by the latter when the insulating glass pane is being conveyed. In this prior art, the L-shaped supports of the rear horizontal conveyor and the support roller line together define a disc running plane. To order with a device according to the DE 30 38 425 C2 To be able to convey insulating glass panes, which have three glass plates parallel to each other, it is known to manually insert strips with support rollers between the rear horizontal conveyor and the front horizontal conveyor, wherein the height of the support rollers is chosen so that their top in alignment with the top of the horizontal Leg of the L-shaped supports is located so that the support rollers can support the middle glass plate of a triple insulating glass pane. It is important to ensure that the support rollers are exactly aligned with the position of the middle glass panel and are so narrow that they do not protrude into the area of the two edge joints of the triple insulating glass panel, because these edge joints are covered with a tough-tacky sealing compound filled, which may stick to misaligned support rollers, which could not only lead to contamination of the insulating glass panes, but would also affect the sealing of the insulating glass panes. It is therefore known to provide for all possible different layers, which can take the middle glass plate of insulating glass in the conveyor adapted thereto different roles bars that have to be changed manually every time an insulating glass pane comes with a changed position of the middle glass plate, and which must be removed by hand each time, when a double insulating glass pane comes instead of a triple insulating glass pane. This is time consuming, reduces the performance of an insulating glass production line, of which the device for conveying insulating glass panes is an integral part, and increases the cost of insulating glass production. For example, for an insulating glass manufacturing line, personnel may need to be adjusted for a second layer if the proportion of triple-glazed panes in the production of insulating glass panes increases at the expense of the proportion of double-glazed panes.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, diesen Nachteilen abzuhelfen.The present invention has for its object to remedy these disadvantages.

Diese Aufgabe wird durch eine Vorrichtung mit den im Patentanspruch 1 angegebenen Merkmalen gelöst. Vorteilhafte Weiterbildungen der Erfindung sind Gegenstand der abhängigen Patentansprüche.This object is achieved by a device having the features specified in claim 1. Advantageous developments of the invention are the subject of the dependent claims.

Die erfindungsgemäße Vorrichtung zum Fördern von Isolierglasscheiben, die drei zueinander parallele Glasplatten haben, nämlich eine vordere Glasplatte, eine hintere Glasplatte und eine mittlere Glasplatte, welche entlang ihrer Ränder durch einen klebenden ersten Abstandhalter und durch einen klebenden zweiten Abstandhalter paarweise auf Abstand voneinander gehalten und miteinander verklebt sind, hat ein Gestell mit einem vorderen Waagerechtförderer und mit einem hinteren Waagerechtförderer, welche mit veränderbarem Abstand voneinander nebeneinander an dem Gestell angebracht sind,
eine um einige Grad gegen die Vertikale nach hinten geneigte Stützeinrichtung zum Abstützen der Isolierglasscheiben, welche mit ihrer hinteren Glasplatte auf dem hinteren Waagerechtförderer und mit ihrer vorderen Glasplatte auf dem vorderen Waagerechtförderer stehen und gegen die Stützeinrichtung gelehnt sind,
wobei die Stützeinrichtung eine Scheibenlaufebene definiert, in welcher die Außenseite der hinteren Glasplatte liegt,
und bewegliche Mittel zum Unterstützen der mittleren Glasplatte der Isolierglasscheiben, welche mittelbar oder unmittelbar am Gestell angebracht sind, dem nach unten weisenden Rand der mittleren Glasplatte anliegen und beim Fördern der Isolierglasscheibe zusammen mit dieser bewegt werden und vorzugsweise von dieser mitgenommen werden.The inventive device for conveying insulating glass panes, the three parallel glass plates, namely a front glass plate, a rear glass plate and a central glass plate, which along its edges by an adhesive first spacer and by an adhesive second spacer in pairs spaced from each other and each other glued, has a frame with a front horizontal conveyor and with a rear horizontal conveyor, which are mounted at a variable distance from each other side by side on the frame,
a support device tilted by a few degrees against the vertical to support the insulating glass panes, which with its rear glass plate on the rear Horizontal conveyor and stand with its front glass plate on the front horizontal conveyor and lean against the support device,
wherein the support means defines a disc running plane in which the outside of the rear glass plate lies,
and movable means for supporting the central glass plate of the insulating glass panes, which are mounted directly on the frame or indirectly, abut the downwardly facing edge of the central glass plate and are moved in conveying the insulating glass together with this and preferably taken away from it.

Die Mittel zum Unterstützen der mittleren Glasplatte sind sowohl in der Höhe als auch in ihrem Abstand von der Scheibenlaufebene maschinell verstellbar am Gestell angebracht und können aus einer wirksamen Stellung, in welcher ihre Oberseite mit der Oberseite wenigstens eines der beiden Waagerechtförderer fluchtet, in eine tiefer liegende unwirksame Stellung gebracht werden.The means for supporting the central glass plate are both mechanically mounted on the frame both in height and at a distance from the pane running plane and can be moved from an operative position in which its upper side is flush with the upper side of at least one of the two horizontal conveyors ineffective position.

Die erfindungsgemäße Vorrichtung hat wesentliche Vorteile:

  • Dadurch, dass am Gestell der Fördervorrichtung die Mittel zum Unterstützen der mittleren Glasplatte einer Dreifach-Isolierglasscheibe sowohl in der Höhe maschinell verstellbar als auch in ihrem Abstand von der Scheibenlaufebene maschinell verstellbar angebracht und aus einer wirksamen Stellung, in welche die Oberseite der Unterstützungsmittel mit der Oberseite wenigstens eines der beiden Waagerechtförderer fluchtet, in eine tiefer liegende unwirksame Stellung gebracht werden können, ist es nicht mehr erforderlich, für unterschiedlich aufgebaute Dreifach-Isolierglasscheiben, in denen die mittlere Glasplatte in der Fördervorrichtung unterschiedliche Abstände von der Scheibenlaufebene einnimmt, eine Anzahl unterschiedlicher Rollenleisten zum Unterstützen der mittleren Glasplatte vorrätig zu halten.
  • Die erfindungsgemäße Fördervorrichtung bringt die Unterstützungsmittel, mit denen sie ausgerüstet ist, nach Bedarf in die richtige Stellung, in welcher sie die mittlere Glasplatte unterschiedlicher Dreifach-Isolierglasscheiben unterstützen zu kann.
  • Für das Positionieren der zum Unterstützen der mittleren Glasplatte vorgesehenen Mittel sind keine Eingriffe von Hand in das Arbeiten der Fördervorrichtung erforderlich.
  • Maschinellen Verstelleinrichtungen, welche die Mittel zum Unterstützen der mittleren Glasplatte sowohl in der Höhe als auch in ihrem Abstand von der Scheibenlaufebene verstellen können, kann die Lage, welche die zum Unterstützen der mittleren Glasplatte vorgesehenen Mittel einnehmen sollen, auf unterschiedliche Weise vorgegeben werden: Eine Möglichkeit besteht darin, bereits aus der Fertigungsplanung für eine Isolierglas-Fertigungslinie, von welcher die erfindungsgemäße Fördervorrichtung ein Bestandteil ist, die Daten über die Art und Abmessungen der Isolierglasscheibe zu übernehmen und in ein Steuergerät einzugeben, welches die Abläufe in der Fertigungslinie und damit auch die erfindungsgemäße Fördervorrichtung steuert. Diese Daten können aus der Fertigungsplanung übernommen und direkt auf elektronischem Wege in das Steuergerät übertragen werden. Die Daten können auch auf einem Datenträger z. B als Barcode, gespeichert sein, der in der Isolierglas-Fertigungslinie zur Steuerung der in ihr enthaltenen Vorrichtungen gelesen wird. Eine andere Möglichkeit besteht darin, Sensoren vorzusehen, welche die Art und die Abmessungen einer jeden zu fördernden Isolierglasscheibe erfassen und die erfindungsgemäße Fördervorrichtung entsprechend steuern. So können die Mittel zum Unterstützen der mittleren Glasplatte in eine unwirksame Stellung gebracht werden, wenn als nächstes eine Isolierglasscheibe kommt, welche nur zwei durch einen Abstandhalter auf Abstand gehaltene Glasplatten aufweist. Kommt jedoch eine Isolierglasscheibe, die drei zueinander parallele Glasplatten hat, die paarweise durch zwei Abstandhalter auf Abstand gehalten sind, dann werden die Mittel zum Unterstützen der mittleren Glasplatte in einen Abstand von der Scheibenlaufebene gebracht, der dem Abstand der mittleren Glasplatte der Dreifach-Isolierglasscheibe von der Scheibenlaufebene entspricht, und zusätzlich werden die Mittel zum Unterstützen der mittleren Glasplatte angehoben bis in die Höhe des unteren Randes der mittleren Glasplatte. Folgt als nächstes eine Dreifach-Isolierglasscheibe, deren mittlere Glasplatte einen anderen Abstand von der Scheibenlaufebene hat als in der vorausgegangenen Dreifach-Isolierglasscheibe, dann müssen die Mittel zum Unterstützen der mittleren Glasplatte nur noch in ihrem Abstand von der Scheibenlaufebene angepasst werden, aber nicht mehr in ihrer Höhe.
  • Die erfindungsgemäße Fördervorrichtung erlaubt eine rationelle Fertigung von Isolierglasscheiben mit niedrigen Personalkosten auch dann, wenn in der Fertigungslinie Zweifach-Isolierglasscheiben und Dreifach-Isolierglasscheiben in willkürlicher Reihenfolge und mit wechselnden Abmessungen aufeinanderfolgen.
  • Die erfindungsgemäße Fördervorrichtung ist beim Fördern von Dreifach-Isolierglasscheiben und beim Fördern von Zweifach- und Dreifach-Isolierglasscheiben in wechselnder Folge ebenso leistungsfähig wie beim Fördern von Zweifach-Isolierglasscheiben.
  • Fehlpositionierungen, die Ausschuss zur Folge haben können, sind praktsich ausgeschlossen.
The device according to the invention has significant advantages:
  • Characterized in that mounted on the frame of the conveyor means for supporting the central glass plate of a triple insulating glass both mechanically adjustable in height and in their distance from the disc running plane and from an operative position in which the top of the support means with the top at least one of the two horizontal conveyor is aligned, can be placed in a lower-lying inactive position, it is no longer necessary for differently constructed triple insulating glass panes, in which the middle glass plate occupies different distances from the disk running plane in the conveyor, a number of different roller bars Support the middle glass plate to keep in stock.
  • The conveyor according to the invention brings the support means with which it is equipped, as needed in the right position in which they can support the middle glass plate of different triple insulating glass panes.
  • The positioning of the means provided to support the central glass plate does not require any manual intervention in the operation of the conveyor.
  • Mechanical adjustment devices which can adjust the means for supporting the central glass plate both in height and in their distance from the pane running plane, the position which the intended to support the central glass plate means are given in different ways: One way consists of already taking over the production planning for an insulating glass production line, of which the conveyor device according to the invention is a part, the data on the type and dimensions of the insulating glass and enter into a control unit, which controls the processes in the production line and thus the invention Conveyor controls. This data can be taken from production planning and transmitted directly to the electronic control unit. The data can also be stored on a data carrier z. B as a bar code, which is read in the insulating glass production line for controlling the devices contained therein. Another possibility is to provide sensors which detect the type and dimensions of each to be conveyed insulating glass and control the conveyor device according to the invention accordingly. Thus, the means for supporting the central glass plate can be brought into an inoperative position when an insulating glass pane comes next, which has only two spaced by a spacer glass plates. However, if an insulating glass panel having three mutually parallel glass plates spaced by a pair of spacers is spaced, the means for supporting the central glass panel are spaced apart from the pane running plane by the distance of the central glass panel of the triple insulating glass pane corresponds to the disk running plane, and in addition the means for supporting the middle glass plate are raised up to the level of the lower edge of the middle glass plate. Next, following a triple-glazed pane whose middle glass plate is at a different distance from the pane running plane than in the previous triple-glazed pane, then the means for assisting must follow the middle glass plate can only be adjusted in their distance from the pane running plane, but not in their height.
  • The conveyor device according to the invention allows a rational production of insulating glass panes with low personnel costs, even if in the production line double insulating glass panes and triple insulating glass panes follow each other in arbitrary order and with changing dimensions.
  • The conveyor device according to the invention is as efficient at conveying triple insulating glass panes and at conveying double and triple insulating glass panes in alternating sequence as when conveying double insulating glass panes.
  • Wrong positioning, which may result in rejection, is virtually excluded.

Die Abstandhalter der Isolierglasscheibe können aus einem metallischen Hohlprofilstab oder aus einem Kunststoff-Hohlprofilstab gebildet sein, welcher ein Trockenmittel enthält und auf seinen den benachbarten Glasplatten zugewandten Flanken mit einer klebenden Dichtmasse beschichtet ist, insbesondere mit einem Polyisobutylen. Der Abstandhalter kann aber auch aus einem Kunststoffstrang bestehen, in den ein Trockenmittel eingelagert ist, wie z. B. der unter dem Handelnamen "Super Spacer" bekannte vorgefertigte elastoplastische Strang, oder wie der unter dem Handelsnamen TPS bekannte thermoplastische Strang, welcher während der Isolierglasfertigung in-situ auf jeweils eine von zwei Glasplatten gespritzt wird.The spacers of the insulating glass pane can be formed from a metallic hollow profile bar or from a plastic hollow profile bar which contains a desiccant and is coated on its flanks facing the adjacent glass panes with an adhesive sealing compound, in particular with a polyisobutylene. The spacer may also consist of a plastic strand in which a desiccant is incorporated, such as. B. known under the trade name "Super Spacer" prefabricated elastoplastic strand, or as the known under the trade name TPS thermoplastic strand, which is injected during the insulating glass in situ on each one of two glass plates.

Der Abstandhalter wird im Allgemeinen mit einem Abstand vom Rand der Isolierglasscheibe, aber in der Nähe des Randes der Isolierglasscheibe angeordnet. Dadurch verbleibt auf der Außenseite des Abstandhalters eine Randfuge, in welche üblicherweise eine zunächst pastöse und danach abbindende Versiegelungsmasse eingefüllt wird und, wenn sie ausgehärtet ist, einen festen Verbund zwischen den Glasplatten der Isolierglasscheibe sicherstellt. Gebräuchliche Versiegelungsmassen für diesen Zweck sind Polysulfide (Thiokole), Polyurethane, Schmelzkleber und Silikonharze. Nachdem eine derartige Versiegelungsmasse in die Randfuge einer Isolierglasscheibe eingefüllt worden ist, ist es wichtig, dass die Isolierglasscheibe, welche üblicherweise hochkant stehend gefördert wird, so gefördert wird, dass jegliche Berührung mit der noch pastösen Versiegelungsmasse vermieden wird. Darauf nimmt die erfindungsgemäße Vorrichtung zum Fördern von Isolierglasscheiben Rücksicht, indem diese ermöglicht, dass die Isolierglasscheiben nur am Rand der Glasplatten und allenfalls noch an den Außenflächen der beiden äußeren Glasplatten berührt werden.The spacer is generally arranged at a distance from the edge of the insulating glass pane, but near the edge of the insulating glass pane. This leaves on the outside of the spacer a marginal joint, in which usually a first pasty and then setting sealing compound is filled and, when cured, ensures a firm bond between the glass plates of the insulating glass. Common sealants for this purpose are polysulfides (thiols), polyurethanes, hot melt adhesives and silicone resins. After such a sealant in the edge joint of an insulating glass pane has been filled, it is important that the insulating glass, which is usually conveyed upright standing, is promoted so that any contact with the still pasty sealant is avoided. Then takes the device according to the invention for conveying insulating glass sheets consideration by this allows that the insulating glass panes are touched only at the edge of the glass plates and possibly even on the outer surfaces of the two outer glass plates.

Der Abstand zwischen dem vorderen Waagerechtförderer und dem hinteren Waagerechtförderer kann verändert werden, um die Fördervorrichtung an unterschiedlich dicke Isolierglasscheiben anzupassen. Dementsprechend sind auch die Mittel zum Unterstützen einer mittleren Glasplatte der Isolierglasscheiben in ihrem Abstand von der Scheibenlaufebene der Fördervorrichtung veränderbar, damit sie stets genau auf die mittlere Glasplatte ausgerichtet werden können. Diese Mittel, welche die mittlere Glasplatte stützen sollen, sind so ausgebildet, dass sie beim Fördern der Isolierglasscheibe zusammen mit dieser bewegt werden. Das bedeutet nicht, dass sie geradlinig in Förderrichtung der Isolierglasscheiben bewegt werden müssen. Das kann zwar der Fall sein, wenn zum Stützen der mittleren Glastafel z. B. ein endloser Riemen eingesetzt wird, welcher parallel zu den beiden Waagerechtförderern verläuft und ein Obertrum hat, welches vorzugsweise durch eine waagerechte Leiste unterstützt ist. Vorzugsweise sind dem Obertrum in diesem Fall seitliche Führungseinrichtungen zugeordnet, welche seitliche Verschiebungen des Obertrums verhindern. Derartige Führungseinrichtungen können dadurch gebildet sein, dass die waagerechte Leiste, welche das Obertrum des Riemens unterstützt, eine Nut hat, in welcher das Obertrum des Riemens verläuft, wobei die beiden Seitenwände der Nut den Riemen führen und gegenüber der Oberseite des Riemens nach unten zurückgesetzt sind, um einen Sicherheitsabstand gegenüber der Versiegelungsmasse in den benachbarten Randfugen der Isolierglasscheiben zu haben.The distance between the front horizontal conveyor and the rear horizontal conveyor can be changed to adapt the conveyor to different thicknesses of insulating glass. Accordingly, the means for supporting a central glass plate of the insulating glass panes are variable in their distance from the disk running plane of the conveyor so that they can always be accurately aligned with the central glass plate. These means, which are intended to support the central glass plate, are designed so that they are moved together with the latter when conveying the insulating glass pane. This does not mean that they have to be moved in a straight line in the conveying direction of the insulating glass panes. This may indeed be the case if, for supporting the middle glass panel z. B. an endless belt is used, which runs parallel to the two horizontal conveyors and has an upper run, which is preferably supported by a horizontal bar. Preferably, the upper run in this case are associated with lateral guide means which prevent lateral displacements of the upper run. Such guide means may be formed in that the horizontal bar which supports the upper run of the belt has a groove in which runs the upper run of the belt, wherein the two side walls of the groove guide the belt and are reset towards the top of the belt down to have a safe distance from the sealing compound in the adjacent edge joints of the insulating glass panes.

Vorzugsweise ist zum Unterstützen der mittleren Glasplatte einer Dreifach-Isolierglasscheibe jedoch eine waagerechte Zeile von Rollen vorgesehen, deren Achsen senkrecht zur Scheibenlaufebene ausgerichtet sind. Damit diese Rollen nur den Rand der mittleren Glasplatte berühren, soll die Lauffläche der Rollen nicht breiter sein als die dünnste zu unterstützende mittlere Glasplatte einer Isolierglasscheibe. Geeignet sind dafür Rollen mit einer Lauffläche, welche nicht breiter als 2 bis 3 mm ist. Entsprechende Maße empfehlen sich auch für den Fall, dass zum Unterstützen der mittleren Glasplatte anstelle von Rollen ein endloser Riemen verwendet wird.Preferably, however, a horizontal row of rollers is provided to support the central glass plate of a triple insulating glass pane, the axes of which are aligned perpendicular to the pane running plane. So that these rollers touch only the edge of the middle glass plate, the running surface of the rollers should not be wider than the thinnest to be supported middle glass plate of an insulating glass pane. Rolls with a tread which are not wider than 2 to 3 are suitable for this purpose mm is. Appropriate dimensions are also recommended in the event that an endless belt is used to support the middle glass plate instead of rollers.

Die Mittel, mit denen die mittlere Glastafel unterstützt wird, können synchron laufend mit den beiden Waagerechtförderern angetrieben sein. Vorzugsweise wird ein Antrieb für diese Mittel jedoch eingespart, denn es genügt, diese Mittel frei beweglich zu lagern. Im Fall von Rollen als Mittel zum Unterstützen der mittleren Glasscheibe werden die Rollen freilaufend gelagert und im Fall der Wahl eines Riemens zur Unterstützung der mittleren Glasscheibe wird der Riemen freilaufend gelagert, wobei eine auftretende Reibung des Riemens herabgesetzt werden kann, indem er durch freilaufende Rollen unterstützt wird. Es hat sich gezeigt, dass die Reibung zwischen dem unteren Rand der mittleren Glasscheibe und den Rollen, die ihn unterstützen oder dem Riemen, der ihn unterstützt, ausreicht, um die Rollen durch den von der Isolierglasscheibe ausgeübten Mitnahmeeffekt in Drehung zu versetzen bzw. den Riemen mitzunehmen, insbesondere dann, wenn wie üblich die Ränder der Glasplatten nicht geschliffen, sondern gebrochen sind.The means by which the middle glass panel is supported can be synchronously driven continuously with the two horizontal conveyors. Preferably, however, a drive for these funds is saved, because it is sufficient to store these funds freely movable. In the case of rollers as means for supporting the central pane of glass, the rollers are mounted in free-running and in the case of choosing a belt to support the central pane of glass, the belt is freewheeling, whereby any friction of the belt can be reduced by supporting by free-running rollers becomes. It has been found that the friction between the lower edge of the middle pane of glass and the rollers that support it or the belt that supports it is sufficient to rotate the rollers by the entrainment effect exerted by the insulating glass pane or the belt take along, especially if, as usual, the edges of the glass plates are not ground, but broken.

In der wirksamen Stellung der Mittel zum Unterstützen der mittleren Glasplatte soll die Oberseite der Mittel mit der Oberseite wenigstens eines der beiden Waagerechtförderer fluchten. Falls es sich bei der Isolierglasscheibe um eine Stufenscheibe handelt, bei welcher eine Glasplatte größer ist als die andere(n) Glasplatte(n) der Isolierglasscheibe, dann soll der die größere Glasplatte aufnehmende Waagerechtförderer in der Höhe verstellbar sein, wie es in der DE 199 09 638 C1 offenbart ist.In the operative position of the means for supporting the central glass plate, the top of the means should be aligned with the top of at least one of the two horizontal conveyors. If the insulating glass pane is a step disk in which one glass plate is larger than the other glass plate (s) of the insulating glass pane, then the horizontal conveyor receiving the larger glass plate should be adjustable in height, as shown in FIG DE 199 09 638 C1 is disclosed.

Die beweglichen Mittel zum Unterstützen der mittleren Glasplatte einer Dreifach-Isolierglasscheibe sind zweckmäßigerweise an oder auf einem waagerechten Träger angeordnet, welcher sich parallel zu den beiden Waagerechtförderern erstreckt und seinerseits verstellbar am Gestell der Fördervorrichtung angebracht ist. Vorzugsweise ist der Träger in zwei zueinander senkrechten Richtungen unabhängig voneinander verstellbar. Das macht es möglich, den Träger unabhängig von einer Veränderung seines Abstandes von der Scheibenlauffläche auf- und abzubewegen und auf diese Weise aus einer wirksamen Stellung, in welcher er die mittlere Scheibe einer Isolierglasscheibe unterstützen kann, lediglich durch Bewegen nach unten in eine unwirksame Stellung bewegbar ist, wenn nämlich z. B. auf eine Dreifach-Isolierglasscheibe eine Zweifach-Isolierglasscheibe folgt. Wenn danach wieder eine Dreifach-Isolierglasscheibe folgt, deren mittlere Scheibe denselben Abstand der Scheibenlauffläche hat wie bei der letzten Dreifach-Isolierglasscheibe, dann muss der Träger nur angehoben, aber nicht sein Abstand von der Scheibenlaufebene verändert werden. Wenn andererseits auf eine erste Dreifach-Isolierglasscheibe eine zweite Dreifach-Isolierglasscheibe folgt, in welcher die mittlere Glasplatte einen anderen Abstand von der Scheibenlaufebene hat als in der ersten Dreifach-Isolierglasscheibe, dann muss lediglich der Abstand des Trägers von der Scheibenlaufebene angepasst werden, während die Höhe beibehalten werden kann.The movable means for supporting the central glass plate of a triple insulating glass pane are expediently arranged on or on a horizontal support, which extends parallel to the two horizontal conveyors and in turn is adjustably mounted on the frame of the conveyor. Preferably, the carrier is independently adjustable in two mutually perpendicular directions. This makes it possible to move the carrier up and down independently of a change in its distance from the disc running surface and thus move from an operative position in which it can support the middle disc of an insulating glass only by moving down to an inoperative position is, if z. B. on a triple-glazed pane followed by a double insulating glass pane. If this is followed by a triple-glazed pane again, the middle pane of which has the same distance of the pane running surface as in the last triple-glazed pane, then the beam only has to be raised, but not its distance from the pane running plane changed. On the other hand, if a first triple insulating glass pane is followed by a second triple insulating glass pane in which the central glass plate is at a different distance from the pane running plane than in the first triple insulating glass pane, then only the distance of the carrier from the pane running plane needs to be adjusted while the Height can be maintained.

Zur Verstellung des Trägers ist eine motorische Verstelleinrichtung, vorzugsweise wenigstens ein Elektromotor, z. B. ein Servomotor, vorgesehen. Grundsätzlich reicht ein einziger Motor, um über entsprechende Getriebeelemente den Abstand des Trägers von der Scheibenlaufebene zu verändern, auch wenn der Träger mehrere Meter lang sein sollte. Der Servomotor ermöglicht ein feinfühliges, zielgenaues Verstellen des Trägers. Für die Auf- und Abbewegung des Trägers wird nicht unbedingt ein Servomotor benötigt. Für die Auf- und Abbewegung kommt man vielmehr mit einem Antrieb aus, welcher den Träger lediglich zwischen einer oberen Endstellung (die wirksame Stellung) und einer unteren Stellung (die unwirksame Stellung) hin und her bewegt. Dafür genügt es, einen oder zwei Kolben-Zylinder-Einheiten vorzusehen, insbesondere Pneumatikzylinder.To adjust the carrier is a motorized adjustment, preferably at least one electric motor, for. B. a servomotor provided. In principle, a single motor is sufficient to change the distance of the carrier from the disk running plane via corresponding gear elements, even if the carrier should be several meters long. The servomotor allows a sensitive, precise adjustment of the carrier. For the up and down movement of the carrier is not necessarily a servomotor needed. For the up and down movement one comes rather with a drive, which moves the carrier only between an upper end position (the active position) and a lower position (the inoperative position) back and forth. For this it is sufficient to provide one or two piston-cylinder units, in particular pneumatic cylinders.

Der Träger für die Mittel zum Unterstützen der mittleren Glasplatte von Isolierglasscheiben ist zweckmäßigerweise am hinteren Waagerechtförderer angebracht. Dieser kann in vielen Fällen stationär angeordnet sein, während der vordere Waagerechtförderer seinen Abstand vom hinteren Waagerechtförderer verändern kann. Es können aber auch beide Waagerechtförderer quer verschieblich sein, wie es in der DE 199 09 638 C2 offenbart ist.The support for the means for supporting the central glass plate of insulating glass is expediently mounted on the rear horizontal conveyor. This can be arranged stationary in many cases, while the front horizontal conveyor can change its distance from the rear horizontal conveyor. But it can also be horizontally displaceable horizontal conveyor, as it is in the DE 199 09 638 C2 is disclosed.

Für Zwecke der Erfindung können unterschiedliche Waagerechtförderer verwendet werden, insbesondere Waagerechtförderer der Art, wie sie in der DE 199 09 638 C2 , in der EP 0 549 648 B1 und in der DE 30 38 425 C2 offenbart sind, wobei Waagerechtförderer des Typs wie sie in der DE 199 09 638 C2 offenbart sind, also mit endlosen Riemen mit waagerecht verlaufendem Obertrum bevorzugt sind. Die waagerechten Obertrums der beiden Waagerechtförderer liegen, soweit nicht Stufenscheiben - wie in der DE 199 09 638 C2 offenbart - gefördert werden sollen, zweckmäßigerweise in einer gemeinsamen Ebene, insbesondere in einer solchen Ebene, welche die Scheibenlaufebene unter einem rechten Winkel schneidet. Zur Veränderung des Abstands der beiden Waagerechtförderer sind diese vorzugsweise unabhängig voneinander querverschieblich am Gestell angebracht, wie in der DE 199 09 638 C2 offenbart.For the purposes of the invention, different horizontal conveyors can be used, in particular horizontal conveyors of the kind as described in US Pat DE 199 09 638 C2 , in the EP 0 549 648 B1 and in the DE 30 38 425 C2 wherein horizontal conveyors of the type as shown in the DE 199 09 638 C2 are disclosed, so are preferred with endless belt with horizontally running upper strand. The horizontal Obertrums of the two horizontal conveyor are, if not stepped discs - as in the DE 199 09 638 C2 disclosed - are to be promoted, expediently in a common plane, in particular in such a plane which intersects the disc running plane at a right angle. To change the distance between the two horizontal conveyor these are preferably mounted independently transversely displaceable on the frame, as in the DE 199 09 638 C2 disclosed.

Bei einem Waagerechtförderer, bei welchem zwei zueinander parallele Förderbänder, wie in der EP 0 549 648 B1 offenbart, V-förmig zueinander angeordnet sind, können die beiden V-förmig zueinander angeordneten Förderbänder in Weiterbildung der in der EP 0 549 648 B1 offenbarten Lehre mit Vorteil ihren Abstand voneinander ändern. Zu diesem Zweck können die beiden V-förmig zueinander angeordneten Förderbänder durch zueinander parallele Träger unterstützt werden, welche ebenfalls V-förmig zueinander auf dem Gestell der Vorrichtung angeordnet und, vorzugsweise unabhängig voneinander, quer zur Förderrichtung verstellbar sind.In a horizontal conveyor, in which two parallel conveyor belts, as in the EP 0 549 648 B1 disclosed, V-shaped are arranged to each other, the two V-shaped conveyor belts arranged in relation to each other in the EP 0 549 648 B1 revealed teaching advantageously change their distance from each other. For this purpose, the two conveyor belts arranged in a V-shape relative to one another can be supported by mutually parallel carriers which are likewise arranged in a V-shape relative to one another on the frame of the device and, preferably independently of one another, can be adjusted transversely to the conveying direction.

Die Figuren 1 und 2 zeigen einen Ausschnitt einer Vorrichtung zum Fördern von Isolierglasscheiben 1, die drei zueinander parallele Glasplatten 2, 3 und 4 haben, nämlich eine vordere Glasplatte 2, ein hintere Glasplatte 3 und eine mittlere Glasplatte 4, welche entlang ihrer Ränder durch einen klebenden ersten Abstandhalter 5 und durch einen klebenden zweiten Abstandhalter 6 paarweise auf Abstand voneinander gehalten und miteinander verklebt sind. Die Vorrichtung hat einen vorderen Waagerechtförderer 7 und einen hinteren Waagerechtförderer 8, welche mit veränderbarem Abstand voneinander parallel nebeneinander an einem nur teilweise dargestellten Gestell 32 angebracht sind. Den Waagerechtförderern 7 und 8 ist eine um einige Grad gegen die Vertikale nach hinten geneigte Stützwand 9 zugeordnet, welche an dem Gestell 32 angebracht ist und zum Abstützen der Isolierglasscheiben 1 dient, welche mit ihrer vorderen Glasplatte 2 auf dem vorderen Waagerechtförderer 7 stehen und mit ihrer hinteren Glasplatte 3 auf dem hinteren Waagerechtförderer 8 stehen und gegen die Stützwand 9 gelehnt sind. Die Stützwand 9 definiert mit ihrer Vorderseite, an welche die Isolierglasscheiben 1 angelehnt sind, eine Scheibenlaufebene, in welcher die Außenseite der hinteren Glasplatte 3 liegt.The FIGS. 1 and 2 show a section of a device for conveying insulating glass panes 1, the three parallel glass plates 2, 3 and 4 have, namely a front glass plate 2, a rear glass plate 3 and a central glass plate 4, which along its edges by an adhesive first spacer 5 and are held by an adhesive second spacer 6 in pairs at a distance from each other and glued together. The device has a front horizontal conveyor 7 and a rear horizontal conveyor 8, which are mounted at a variable distance from each other parallel to each other on a frame 32 only partially shown. The horizontal conveyors 7 and 8 is assigned by a few degrees against the vertical rearwardly inclined support wall 9 which is mounted on the frame 32 and serves to support the insulating glass panes 1, which stand with its front glass plate 2 on the front horizontal conveyor 7 and with her stand back glass plate 3 on the rear horizontal conveyor 8 and are leaned against the support wall 9. The support wall 9 defines with its front side, to which the insulating glass panes 1 are ajar, a pane running plane in which the outside of the rear glass plate 3 lies.

Ein waagerechter Balken 33 ist Bestandteil des Gestells 32; er verläuft parallel zur ebenen Vorderseite der Stützwand 9 unterhalb von deren unteren Rand und trägt den vorderen Waagerechtförderer 7. Dieser hat an einer waagerechten, langgestreckten Traverse 10 zwei Rollen 11, von denen eine angetrieben ist. Über die Rollen 11 ist ein endloser Riemen 12 gespannt, dessen Obertrum 13 z. B. durch eine waagerechte Leiste 35 unterstützt ist, welche sich zwischen den beiden Rollen 11 erstreckt und Bestandteil der Traverse 10 sein kann. Die Traverse 10 ist im rechten Winkel zur ebenen Vorderseite der Stützwand 9 verschieblich auf dem Balken 33 gelagert und zu diesem Zweck mittels Gleitführungseinrichtungen 34 geführt.A horizontal bar 33 is part of the frame 32; it runs parallel to the flat front of the support wall 9 below the lower edge and carries the front horizontal conveyor 7. This has on a horizontal, elongated cross member 10 two rollers 11, one of which is driven. About the rollers 11, an endless belt 12 is stretched, the upper strand 13 z. B. is supported by a horizontal bar 35 which extends between the two rollers 11 and may be part of the traverse 10. The Traverse 10 is in the right Angle to the flat front of the support wall 9 slidably mounted on the beam 33 and guided for this purpose by means of Gleitführungseinrichtungen 34.

Entsprechend ist der hintere Waagerechtförderer 8 durch zwei an einer waagerechten Traverse 14 angebrachte Rollen 15, von denen eine angetrieben ist, gebildet, über welche ein endloser Riemen 16 gespannt ist, dessen Obertrum 17 z. B. von einer Leiste 36 unterstützt ist, welche sich zwischen den beiden Rollen 15 erstreckt und Bestandteil der Traverse 14 sein kann. Die Traverse 14 ist wie die Traverse 10 am Gestell 32 der Fördervorrichtung angebracht und beide Traversen 10 und 14 sind senkrecht zur ebenen Vorderseite der Stützwand 9 unabhängig voneinander verstellbar, wodurch nicht nur der Abstand der Rollen 11 und 15 von der Vorderseite der Stützwand 9, sondern auch der Abstand der Rollen 11 und 15 voneinander veränderbar ist.Accordingly, the rear horizontal conveyor 8 by two mounted on a horizontal cross member 14 rollers 15, one of which is driven, is formed, over which an endless belt 16 is stretched, the upper strand 17 z. B. is supported by a bar 36 which extends between the two rollers 15 and may be part of the traverse 14. The traverse 14 is like the cross member 10 mounted on the frame 32 of the conveyor and both trusses 10 and 14 are perpendicular to the flat front of the support wall 9 independently adjustable, thereby not only the distance of the rollers 11 and 15 from the front of the support wall 9, but and the distance between the rollers 11 and 15 is variable from each other.

Ein zum vorderen Balken 33 paralleler Balken 36, welcher am Gestell 32 angebracht ist und für das Fördern von Stufenscheiben in der Höhe verstellbar sein kann, ist nicht dargestellt. Unter einer Stufenscheibe wird eine Isolierglasscheibe verstanden, in welcher eine Glasplatte - beim Fördern mit der erfindungsgemäßen Vorrichtung ist es die hintere Glasplatte 3 - größer ist als die anderen Glasplatten der Isolierglasscheibe, so dass ihr unterer Rand beim Fördern tiefer liegt als der untere Rand der vorderen Glasplatte 2 der Isolierglasscheibe. An diesem nicht dargestellten Balken, welcher sich parallel zum vorderen Balken 33 erstreckt, ist die in den Figuren 4 bis 7 dargestellte Einrichtung befestigt. Diese Einrichtung hat eine waagerechte Platte 20, an welcher zwei senkrechte Montageplatten 21 angebracht sind, welche mit dem Träger 37 verschraubt sind. Die Platte 20 trägt zwei in einem Gehäuse untergebrachte Getriebe 22 und 23, welche mit einem im Getriebegehäuse befindlichen und daher nicht dargestellten Ritzel in je eine Zahnstange 24 bzw. 25 eingreifen. Die beiden Zahnstangen 24 und 25 verlaufen parallel zueinander und durchsetzen das jeweilige Getriebegehäuse.A parallel to the front beam 33 bar 36 which is mounted on the frame 32 and can be adjusted for the conveyance of step plates in height, is not shown. A step disc is understood to mean an insulating glass pane in which a glass plate - when conveying with the device according to the invention, it is the rear glass plate 3 - is larger than the other glass plates of the insulating glass pane, so that its lower edge during conveying is lower than the lower edge of the front Glass plate 2 of the insulating glass pane. At this beam, not shown, which extends parallel to the front beam 33, which is in the FIGS. 4 to 7 attached device attached. This device has a horizontal plate 20 to which two vertical mounting plates 21 are mounted, which are bolted to the carrier 37. The plate 20 carries two housed in a housing gear 22 and 23, which engage with a located in the gear housing and therefore not shown pinion in a respective rack 24 and 25 respectively. The two racks 24 and 25 are parallel to each other and enforce the respective gear housing.

Am Getriebe 22 ist eine motorische Verstelleinrichtung, insbesondere ein Servomotor 26, angebracht, welcher das Getriebe 22 und über eine Welle 27, welche die beiden Getriebe 22 und 23 miteinander koppelt, auch das Getriebe 23 antreibt. Auf diese Weise bewegt der Servomotor 26 synchron die beiden Zahnstangen 24 und 25. An den beiden Zahnstangen 24 und 25 ist ein Träger 28, insbesondere eine waagerechte Leiste 28, befestigt, welche eine Reihe von freilaufenden Rollen 29 trägt, deren Achsen in gleicher Höhe parallel zueinander verlaufen, und zwar senkrecht zur Vorderseite der Stützwand 9.On the gear 22, a motor adjusting device, in particular a servomotor 26, mounted, which drives the gearbox 22 and via a shaft 27, which couples the two gearboxes 22 and 23 together, the transmission 23. In this way, the servomotor 26 synchronously moves the two racks 24 and 25. An the two racks 24 and 25, a support 28, in particular a horizontal bar 28, fixed, which carries a series of free-running rollers 29, whose axes are parallel to each other at the same height, perpendicular to the front of the support wall. 9

Zwei Druckmittelzylinder 30 und 31, welche an den Montageplatten 21 angebracht sind, können die Getriebe 22 und 23 und mit ihnen die Leiste 28 mit den Rollen 29 relativ zu den Montageplatten 21 und damit relativ zu dem nicht dargestellten hinteren Balken in eine obere wirksame Stellung heben bzw. in eine untere, unwirksame Stellung senken. Die wirksame obere Stellung ist in Figur 2 gestrichelt dargestellt. In dieser Stellung wird die Leiste 28 mit Hilfe von zwei weiteren Druckmittelzylindern 37 und 38 verriegelt und unterstützt die Leiste 28 mit den Rollen 29 die mittlere Glasplatte 4. In der unteren Stellung, welche in Figur 2 in ausgezogenen Linien dargestellt ist, ist die Leiste 28 mit den Rollen 29 unwirksam und kann in eine der Traverse 14 angenäherte Parkstellung zurückgezogen sein, wozu die Zahnstangen 24 und 25 bei Blickrichtung wie in Figur 2 nach links bewegt werden.Two pressure cylinder 30 and 31, which are attached to the mounting plates 21, the gear 22 and 23 and with them the bar 28 with the rollers 29 relative to the mounting plates 21 and thus relative to the rear beam, not shown, lift into an upper operative position or lower to a lower, inactive position. The effective upper position is in FIG. 2 shown in dashed lines. In this position, the bar 28 is locked by means of two further pressure medium cylinders 37 and 38 and supports the bar 28 with the rollers 29, the middle glass plate 4. In the lower position, which in FIG. 2 shown in solid lines, the bar 28 with the rollers 29 is ineffective and can be withdrawn in one of the traverse 14 approximate parking position, including the racks 24 and 25 in the viewing direction as in FIG. 2 to be moved to the left.

Figur 3 zeigt die Vorrichtung aus Figur 2 mit der Leiste 28 und mit den auf dieser gelagerten Rollen 29 in ihrer Parkstellung und die Waagerechtförderer 7 und 8 in einer im Vergleich zur Figur 2 einander stärker angenäherten Stellung, in welcher die Riemen 17 und 13 die beiden Glasplatten 2 und 3 einer Zweifach-Isolierglasscheibe 1 unterstützen. In beiden Fällen, sowohl in Figur 2 als auch in Figur 3, bleibt die Randfuge zwischen den Glasplatten 2 und 3 in Figur 3 bzw. zwischen den Glasplatten 3 und 4 sowie 2 und 4 in Figur 2 vollständig frei, so dass weder die Riemen 13 und 17 noch die Rollen 29 mit Versiegelungsmasse in Berührung kommen, welche in die Randfugen 18 eingefüllt sein kann.
