Abstract

In a method for round-cornering plane, rectangular, narrow panes (2) made of brittle material such as glass or glass ceramic, the panes are first of all moved on a wide conveying belt (1) by means of a slide (3) into a first position (A) offset to the outside relative to the centre line of the conveying belt and are then guided in a clamped manner. The external corners are then rounded (B) by means of a grinding wheel (6). After the clamping is removed, the panes are moved to the other side into an offset position (C) relative to the centre line of the conveying belt (1) and the two remaining corners are rounded (D) by means of a further grinding wheel (10). To support the panes, one narrow auxiliary conveying belt (5, 9) each is guided on each side of the conveying belt (Fig. 1). <IMAGE>

Description

Die Erfindung betrifft ein Verfahren zum Eckenstoßen von planen, rechteckigen Scheiben aus sprödem Material wie Glas oder Glaskeramik, bei welchem die Scheiben auf Transportriemen in horizontaler Lage festgehalten und transportiert werden und Schleifscheiben während des Transports um die zu stoßenden Ecken der Scheiben herumgeführt werden.The invention relates to a method for corner bumping of flat, rectangular disks made of brittle material such as glass or glass ceramic, in which the disks are held and transported in a horizontal position on conveyor belts and grinding disks are guided around the corners of the disks to be butted during transportation.

Verfahren zum Eckenstoßen werden eingesetzt, um die scharfkantigen Ecken von Glas- oder Glaskeramikscheiben abzuschrägen.Corner butting methods are used to chamfer the sharp-edged corners of glass or glass ceramic panes.

Bei den bekannten Verfahren zum Eckenstoßen werden die Scheiben auf zwei schmalen Transportriemen befördert, die im allgemeinen eine Breite von jeweils 15 mm aufweisen. Auf diesen Transportriemen werden die Scheiben zur Eckenstoßvorrichtung transportiert, die während des Bearbeitungsvorgangs mitbewegt wird Beim Einlaufen in die Eckenstoßvorrichtung werden zwei um eine vertikale Achse rotierende Schleifscheiben, wovon je eine auf jeder Seite neben den Transportriemen angeordnet ist, vor der zu bearbeitenden Scheibe einwärts aufeinander zubewegt, anschließend an die Scheibe angelegt und um die beiden vorderen zu stoßenden Ecken herumgeführt. Danach werden die beiden Schleifscheiben zu den in Transportrichtung hinteren Ecken geführt, an die zu bearbeitenden Ecken angelegt und um die Ecken herum nach innen geführt In dieser Position verbleiben die Schleifscheiben, bis die nächste Scheibe in die Eckenstoßvorrichtung einläuft.In the known methods for corner bumping, the disks are transported on two narrow transport belts, which generally have a width of 15 mm each. On these transport belts, the discs are transported to the corner bumping device, which is also moved during the machining process.When entering the corner bumping device, two grinding discs rotating around a vertical axis, one on each side next to the transport belt, are moved inwards towards each other in front of the disc to be processed , then placed on the pane and led around the two front corners to be butted. The two grinding wheels are then guided to the corners at the rear in the direction of transport, placed against the corners to be machined and guided inwards around the corners. The grinding wheels remain in this position until the next wheel enters the corner jointing device.

Dieses Verfahren hat den Nachteil, daß nur Platten mit einer Mindestbreite, die im wesentlichen durch die Breite der Transportriemen und den Platzbedarf der Schleifscheiben festgelegt ist, bearbeitet werden können. Im Falle der 15 mm breiten Transportriemen muß die Scheibe mindestens 90 mm breit sein.This method has the disadvantage that only plates with a minimum width, essentially due to the width of the conveyor belt and the space required for the grinding wheels is fixed, can be edited. In the case of the 15 mm wide transport belts, the pulley must be at least 90 mm wide.

Schmalere Scheiben stehen auf beiden Seiten der Transportriemen nicht genügend oder gar nicht über, so daß die Transportriemen durch die Schleifscheiben, deren Durchmesser nicht beliebig klein gewählt werden kann, beschädigt werden.Narrow disks do not protrude sufficiently or not at all on both sides of the conveyor belts, so that the conveyor belts are damaged by the grinding disks, the diameter of which cannot be chosen to be as small as desired.

Um auch schmalere Scheiben bearbeiten zu können, wurden die Scheiben vor dem Eckenstoßen gedreht, so daß die Längsachse der Scheibe mit der Transportrichtung einen Winkel von 90° bildet. Voraussetzung ist jedoch, daß diese Scheiben eine Mindestlänge aufweisen, um ausreichend auf beiden Seiten der Transportriemen überzustehen.In order to be able to machine narrower panes, the panes were rotated before the corners were pushed so that the longitudinal axis of the pane forms an angle of 90 ° with the transport direction. The prerequisite, however, is that these disks have a minimum length in order to be able to protrude sufficiently on both sides of the conveyor belts.

Dieses Verfahren hat jedoch den Nachteil, daß eine exakte Ausrichtung der Scheiben nicht möglich ist, weil die Scheiben bei der Positionierung nur mit den Schmalseiten an den Anschlägen anliegen.However, this method has the disadvantage that an exact alignment of the disks is not possible because the disks only rest against the stops with the narrow sides during positioning.

Ziel der vorliegenden Erfindung ist daher ein Verfahren zum Eckenstoßen, bei dem eine Drehung der Scheiben vermieden wird, die Scheiben exakt positioniert werden und herkömmliche Eckenstoßvorrichtungen verwendet werden können.The aim of the present invention is therefore a method for corner bumping, in which rotation of the panes is avoided, the panes are precisely positioned and conventional corner bumpers can be used.

Dieses Ziel wird mit einem Verfahren zum Eckenstoßen erreicht, bei dem zum Eckenstoßen von schmalen Scheiben diese Scheiben auf einem breiten Transportriemen zunächst in einer ersten Position geklemmt geführt werden, in der die Scheiben bezüglich der Mittellinie des Transportriemens nach einer Seite nach außen versetzt sind, wobei auf jeder Seite des Transportriemens je ein Schmaler Hilfstransporttiemen geführt wird, in dieser ersten Position die beiden außenliegenden Ecken der Scheiben gestoßen werden, worauf die Scheiben nach Wegnahme der Klemmung in eine zweite Position gebracht und dann in dieser Position geklemmt geführt werden, in welcher die Scheiben bezüglich der Mittellinie des Transportriemens nach der anderen Seite nach außen versetzt sind, und bei dem in dieser zweiten Position die beiden übrigen Ecken gestoßen werden.This goal is achieved with a method for corner bumping, in which, for corner bumping of narrow panes, these panes are first guided clamped on a wide conveyor belt in a first position in which the panes are offset to one side with respect to the center line of the conveyor belt, whereby A narrow auxiliary transport belt is guided on each side of the transport belt, in this first position the two outer corners of the discs are pushed, whereupon the discs are removed to a second position after removal of the clamping and then guided in this position in which the discs offset to the outside with respect to the center line of the conveyor belt and, in this second position, the two remaining corners are pushed.

Bevorzugt werden die schmalen Hilfstransportriemen auf gleicher Höhe geführt wie der breite Transportriemen, wenn die Scheiben nicht geklemmt werden. Nach erfolgter Klemmung werden die Hilfstransportriemen nach unten weggeführt, damit sie die Beweglichkeit der Schleifscheiben nicht einschränken.The narrow auxiliary conveyor belts are preferably guided at the same height as the wide conveyor belt if the disks are not clamped. After clamping, the auxiliary conveyor belts are moved downwards so that they do not restrict the mobility of the grinding wheels.

Eine beispielhafte Ausführungsform der Erfindung wird nachfolgend anhand der Zeichnung näher erläutert.An exemplary embodiment of the invention is explained in more detail below with reference to the drawing.

Show it:
Figure 1
2 shows a schematic representation of the method according to the invention (top view),
Figure 2
a side view of the arrangement of transport, clamping and auxiliary transport belts.

In Figur 1 ist das erfindungsgemäße Verfahren in vier Abschnitte A bis D unterteilt.In Figure 1, the inventive method is divided into four sections A to D.

Im Verfahrensabschnitt A wird die auf dem breiten Transportriemen 1 liegende extrem schmale Scheibe 2 mittels des Schiebers 3 soweit nach rechts verschoben, bis die Scheibe 2 mit ihrer Längskante an dem Anschlag 4 anliegt (erste Positionierung). Der Anschlag 4 besteht im allgemeinen aus mehreren Rollen. Je nach Breite der Scheibe 2 wird der Schieber 3 mehr oder weniger weit über den Transportriemen 1 geführt.In process section A, the extremely narrow disc 2 lying on the wide transport belt 1 is shifted to the right by means of the slider 3 until the disc 2 lies against the stop 4 with its longitudinal edge (first positioning). The stop 4 generally consists of several roles. Depending on the width of the disc 2, the slider 3 is guided more or less far over the conveyor belt 1.

Zur Abstützung der Scheibe 2 wird auf gleicher Höhe wie der Transportriemen 1 ein schmaler Hilfstransportriemen 5 geführt.To support the disc 2, a narrow auxiliary transport belt 5 is guided at the same height as the transport belt 1.

Nach dieser Ausrichtung wird die Scheibe zum Abschnitt B transportiert. Gleichzeitig erfolgt mittels des Riemens 11 (Fig. 2), der mit gleicher Geschwindigkeit wie der Transportriemen bewegt wird, eine Klemmung der Scheibe. Außerdem wird der Hilfstransportriemen 5 nach unten weggeführt.After this alignment, the disc is transported to section B. At the same time, the pulley is clamped by means of the belt 11 (FIG. 2), which is moved at the same speed as the transport belt. In addition, the auxiliary conveyor belt 5 is guided downward.

So auf dem Transportriemen 1 fixiert wird die Scheibe in die Eckenstoßvorrichtung transportiert, wo eine Schleifscheibe 6 zunächst um die vordere zu stoßende rechte Ecke und anschließend um die hintere rechte Ecke geführt wird, wobei die Ecken in der gewünschten Art und Weise gestoßen werden.So fixed on the conveyor belt 1, the disc is transported into the corner bumping device, where a grinding wheel 6 is first passed around the front right corner to be bumped and then around the rear right corner, the corners being bumped in the desired manner.

Danach wird die Klemmung mittels des Klemmriemens 11 weggenommen und die Scheibe wird mittels des zweiten Schiebers 7 soweit nach links verschoben, bis die Scheibe an dem Anschlag 8 anliegt (2. Position).Then the clamping is removed by means of the clamping belt 11 and the pulley is shifted to the left by means of the second slide 7 until the pulley abuts the stop 8 (2nd position).

Ein zweiter schmaler Hilfstransportriemen 9 stützt hierbei die Scheibe 2 ab. Nach der Klemmung erfolgt im Verfahrensabschnitt D das Eckenstoßen mittels einer zweiten Schleifscheibe 10 auf gleiche Weise wie im Abschnitt B. Dadurch, daß die Scheiben mit ihrer Längskante an den Anschlägen 4, 8 anliegen, erfolgt immer eine exakte Ausrichtung der Scheiben.A second narrow auxiliary conveyor belt 9 supports the pulley 2. After clamping, in process section D, corner bumping is carried out by means of a second grinding wheel 10 in the same way as in section B. Because the wheels lie with their longitudinal edges against the stops 4, 8, the wheels are always precisely aligned.

In Figur 2 ist die Führung der verschiedenen Riemen dargestellt. Die Hilfstransportriemen 5, 9 werden in den Abschnitten A und C, wo die Scheibe positioniert wird, auf gleicher Höhe wie der Transportriemen 1 geführt. In den Abschnitten B und D, wo das Eckenstoßen erfolgt und die Platte 2 mittels des Klemmriemens 11 auf dem breiten Transportriemen 1 fixiert wird, werden die Hilfstransportriemen 5, 9 nach unten weggeführt, um nicht die Beweglichkeit der Schleifscheiben einzuschränken.The guidance of the various belts is shown in FIG. The auxiliary transport belts 5, 9 are guided in sections A and C, where the pulley is positioned, at the same height as the transport belt 1. In sections B and D, where the corner bumping takes place and the plate 2 is fixed on the wide transport belt 1 by means of the clamping belt 11, the auxiliary transport belts 5, 9 are guided downwards in order not to restrict the mobility of the grinding wheels.

Bei einer Umstellung des Bearbeitungsverfahrens auf breite Scheiben, die einen ausreichenden seitlichen Überstand aufweisen, wird die gesamte Vorrichtung mit den Abschnitten A bis D seitlich aus der Bearbeitungsstraße herausgeschoben und durch herkömmliche Transportriemen ersetzt.When the processing method is switched to wide disks which have sufficient lateral protrusion, the entire device with the sections A to D is pushed out of the processing line laterally and replaced by conventional conveyor belts.
