Abstract
Description
Die Erfindung betrifft eine Vorrichtung zum Aufteilen von Verbundglastafeln nach dem Oberbegriff des Anspruchs 1.The invention relates to a device for dividing laminated glass sheets according to the preamble of the claim 1.
In einer bekannten Verbundglasschneidanlage, in der eine horizontal auf einem Auflagetisch gelagerte Verbundglasrohtafel aufgeteilt wird, wird die Verbundglasrohtafel gegenüberliegend unten und oben gleichzeitig geritzt bzw. geschnitten, an einer oberen und unteren Brechleiste positioniert und mit balkenförmigen, sich parallel zur Ritzlinie erstreckenden, an ihren Enden mit Kraftmitteln beaufschlagten Niederhaltern im Bereich der Ritzlinie geklemmt. Danach wird der untere Ritz bzw. Schnitt durch Anheben der unteren Brechleiste und anschließend der obere Schnitt durch Absenken der oberen Brechleiste gebrochen. In der Folge wird dann die noch über die Verbundfolie zusammenhängende und von den Niederhaltern geklemmte Verbundglastafel zwischen Heizstrahlern positioniert, die die Folie im Bereich der Bruchkanten erwärmen. Nach der plastifizierenden Erwärmung werden die durch den Bruch entstandenen Verbundglasteile der Tafel mit den Niederhaltern auseinandergezogen, wobei die plastifizierte Folie getrennt wird.In a known laminated glass cutting machine, in which a laminated glass sheet horizontally supported on a support table is divided, the laminated glass raw panel is opposite carved or cut at the top and bottom, on an upper one and lower crushing bar positioned and with bar-shaped, extending parallel to the scoring line, with force means at their ends clamped clamps clamped in the area of the scoring line. Then the lower scoring or cut is made by lifting the lower one Crowbar and then the upper cut broken by lowering the upper breaker bar. As a result, it is still over the composite film is contiguous and laminated glass panels clamped by the hold-down clamps between radiant heaters positioned, which heat the film in the area of the breaking edges. To plasticizing heating become the laminated glass parts of the panel that resulted from the break pulled apart with the hold-down, the plasticized Film is separated.
Andere Verbundglasschneidanlagen arbeiten mit schwenkbaren Wärmequellen und brechen durch Verschwenken von Verbundglastafelauflagern.Other laminated glass cutting systems work with swiveling heat sources and break by pivoting laminated glass sheet supports.
Für das Auseinanderziehen der durch Ritzen und Brechen aufgeteilten Verbundglasteile müssen letztere mit relativ hohen Kräften mit den Niederhalterbalken niedergehalten werden, damit sie während des Auseinanderziehens nicht verrutschen. Es bleibt dabei nicht aus, daß Verbundglasscheiben zerdrückt werden. Häufig ist dies der Fall, wenn Verbundglasteile niedergehalten werden, die nicht die gesamte Breite des Auflagetisches einnehmen, wobei meist Kantenbruch auftritt.For the pulling apart of those divided by scratching and breaking Laminated glass parts must be the latter with relatively high forces be held down with the hold-down bar so that Don't pull apart. It does not fail that laminated glass panes be crushed. Frequently this is the case when laminated glass parts are held down, that do not occupy the entire width of the table, whereby mostly edge break occurs.
Zweck der Erfindung ist, ein Zerdrücken der Verbundglasteile beim Aufteilen zu vermeiden.The purpose of the invention is to crush the laminated glass parts to avoid when dividing.
Aufgabe der Erfindung ist, die Klemmkräfte der Niederhalterbalken derart zu beeinflussen, daß ein Zerdrücken von Verbundglasteilen ausgeschlossen werden kann.The object of the invention is the clamping forces of the To hold down beams so that crushing of laminated glass parts can be excluded.
Diese Aufgabe wird durch die Merkmale des Anspruchs 1 gelöst. Vorteilhafte Weiterbildungen der Erfindung werden in den von diesen Ansprüchen abhängigen Unteransprüchen gekennzeichnet.This task is due to the characteristics of claim 1 solved. Advantageous developments of the invention are in the of these claims dependent dependent claims characterized.
Anhand der Zeichnung wird die Erfindung im folgenden beispielhaft näher erläutert. Es zeigen:Based on the drawing, the invention in the following as an example explained. Show it:

Im folgenden wird die Funktionsweise der erfindungsgemäßen Vorrichtung erläutert:The following is how it works the device according to the invention explains:
Eine zu schneidende Glastafel
Bei einer weiteren Verfahrensweise wird die Glasplatte zum Schneiden nicht geklemmt, sondern zunächst oberseitig und/oder unterseitig geschnitten, wobei mit einem Wegaufnehmer die Schnittlänge und damit die Breite der Glasplatte erfaßt wird. Nachdem die Breite der Glasplatte derart erfaßt wurde, werden zum anschließenden Klemmen der Glasplatte die entsprechenden Kolbenzylindereinheiten aktiviert.Another approach the glass plate is not clamped for cutting, but first on the top and / or cut on the underside, the cutting length and thus the width of the glass plate is detected. After the width the glass plate so captured has been added to the subsequent one Clamp the glass plate the corresponding piston cylinder units activated.
Ferner ist es möglich, die Klemmbalken vor dem Schneiden solange auf die Glasplatte abzusenken, bis sie diese berühren und anschließend das Schneiden zu beginnen, wobei die Kolbenzylindereinheiten nacheinander entsprechend des eben zurückgelegten Weges des Wegaufnehmers bzw. des Schneidrades aktiviert werden.It is also possible to the clamping bar before Cut on the glass plate until you touch it and subsequently to start cutting, with the piston-cylinder units in succession according to the one just covered Path of the transducer or the cutting wheel can be activated.
Bei der erfindungsgemäßen Vorrichtung ist von Vorteil, daß der oder die Klemmbalken nur dort, wo eine Glasscheibe auf dem Bearbeitungstisch liegt, mit Kraft durch die Kolbenzylindereinheiten beaufschlagt wird bzw. werden, so daß ein Herunterbie gen des Klemmbalkens über eine Glaskante hinaus und damit das Brechen der Glaskante verhindert wird.In the device according to the invention is advantageous that the or the clamping bars only where there is a glass pane on the processing table, force is exerted by the piston-cylinder units or be so that a Bending down the clamp bar a glass edge and thus the breaking of the glass edge is prevented.
