Description

Die Erfindung betrifft eine Vorrichtung zum Reinigen von Glastafeln mit wenigstens einer Bandbürste, die sich auf ihrer der zu reinigenden Glastafeln zugekehrten Seite mit an der Glastafel anliegenden Borsten von oben nach unten bewegt und mit einer Fördervorrichtung für den Transport der im wesentlichen vertikal stehenden Glastafeln durch die Vorrichtung.The invention relates to a device for cleaning glass sheets with at least one ribbon brush, which moves on its side facing the glass sheets to be cleaned with bristles lying against the glass sheet, from top to bottom, and with a conveying device for the transport of the substantially vertical glass sheets through the Contraption.

Bei derartigen Vorrichtungen, wie sie z. B. aus der DE-A-3 333 175 bekannt sind, ergeben sich im Bereich der oberen horizontalen Kante der zu reinigenden Glastafeln Schwierigkeiten. Diese Schwierigkeiten entstehen dadurch, daß die Borsten der sich von oben nach unten bewegenden Bandbürste an der oberen Kante anschlagen und von der Glastafel weg federn, so daß der oberste Rand der Glastafel nicht gereinigt wird. Dieser nicht gereinigte Streifen kann bei höheren Geschwindigkeiten (etwa 5 m/sec) der Bandbürsten eine Breite bis zu 6 cm haben.In such devices, as z. B. are known from DE-A-3 333 175, difficulties arise in the region of the upper horizontal edge of the glass panels to be cleaned. These difficulties arise because the bristles of the ribbon brush moving from top to bottom hit the upper edge and spring away from the glass sheet so that the top edge of the glass sheet is not cleaned. This strip, which has not been cleaned, can have a width of up to 6 cm at higher speeds (approximately 5 m / sec) of the belt brushes.

Durch das ständige Aufprallen der Borsten an die obere horizontale Kante der zu reinigenden Glastafel unterliegen die Borsten der Bandbürste auch einem besonders hohen Verschleiß. Dabei ist zu bedenken, daß die Bruchkanten von Glastafeln insbesondere, wenn es sich um dickere Glastafeln handelt, sehr scharf sind und sich oft nach oben abstehende, scharfkantige Ränder ergeben.Due to the constant impact of the bristles on the upper horizontal edge of the glass sheet to be cleaned, the bristles of the ribbon brush are also subject to particularly high wear. It should be borne in mind that the broken edges of glass panels are very sharp, especially when thicker glass panels are involved, and that sharp-edged edges often protrude upwards.

Ein weiterer Nachteil bei der Verwendung von Bandbürsten zur Reinigung von Glastafeln ergibt sich, wenn einander gegenüberliegende Bandbürstenpaare verwendet werden, da sich die Borsten der der zu reinigenden Glastafeln zugekehrten Trume der Bandbürsten ineinander verzahnen und beim Auftreffen auf den oberen Rand der zu reinigenden Glastafel wieder voneinander getrennt werden müssen, was durch das Auftreffen der Borsten auf dem oberen Rand der Glastafel besonders schwierig ist.A further disadvantage when using ribbon brushes for cleaning glass sheets arises when pairs of ribbon brushes lying opposite one another are used, since the bristles of the strands of the ribbon brushes facing the glass sheets to be cleaned interlock and when they hit the upper edge of the glass sheet to be cleaned again must be separated, which is particularly difficult because the bristles hit the upper edge of the glass sheet.

All diese Probleme treten insbesondere bei der Verwendung von breiteren Bandbürsten auf, die Breiten bis zu 1 m und mehr haben können.All of these problems occur particularly when using wider band brushes that can be up to 1 m wide and more.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung der eingangs genannten Gattung derart weiterzubilden, daß ohne Beeinträchtigung der Reinigungswirkung Bandbürsten mit längeren Borsten verwendet werden können, die im wenigstens teilweise gebogenen Zustand an der zu reinigenden Fläche der Glastafel anliegen und auf dieser neben der Reinigungs-, bevorzugt auch eine Polierwirkung ausüben.The invention has for its object to develop a device of the type mentioned in such a way that tape brushes with longer bristles can be used without impairing the cleaning effect, which lie in the at least partially bent state on the surface of the glass sheet to be cleaned and on this in addition to the cleaning , preferably also exert a polishing effect.

Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß der Bandbürste gegenüberliegend ein unmittelbar über dem oberen Rand der zu reinigenden Glastafel angeordnetes, zur Ebene der Glastafel geneigtes Leitelement vorgesehen ist, dessen unterer, der oberen Kante der Glastafel benachbarter Rand in der Ebene der der Bandbürste zugekehrten Fläche der Glastafel angeordnet ist.According to the invention, this object is achieved in that the ribbon brush is provided with a guide element arranged directly above the upper edge of the glass sheet to be cleaned and inclined to the plane of the glass sheet, the lower edge of which is adjacent to the upper edge of the glass sheet in the plane of the surface facing the ribbon brush the glass panel is arranged.

Durch das erfindungsgemäß vorgeschlagene, geneigte Leitelement werden die Borsten, bevor sie zur Glastafel gelangen, nach und nach und schonend in die Ebene der zu reinigenden Fläche der Glastafel, d. i. die der Bandbürste zugekehrte Seite der zu reinigenden Glastafel, umgelenkt. Durch die Verwendung des erfindungsgemäß vorgeschlagenen Leitelementes entsteht im Bereich des oberen Randes der Glastafel kein von den Borsten nicht bestrichener Bereich mehr und der Verschleiß der Borsten durch Auftreffen derselben auf den oberen Rand der Glastafel ist praktisch völlig ausgeschaltet.By means of the inclined guide element proposed according to the invention, the bristles are gradually and gently moved into the plane of the surface of the glass sheet to be cleaned, ie. i. the side of the glass panel to be cleaned facing the ribbon brush is deflected. By using the guide element proposed according to the invention, in the area of the upper edge of the glass sheet there is no longer any area not covered by the bristles and the wear of the bristles by impacting them on the upper edge of the glass sheet is practically completely eliminated.

Bei der erfindungsgemäßen Vorrichtung können längere und weichere Borsten verwendet werden, die eine bessere und schonendere Reinigungswirkung als kürzere und steifere Borsten entfalten.In the device according to the invention, longer and softer bristles can be used, which have a better and gentler cleaning effect than shorter and stiffer bristles.

Mit Vorteil ist im Rahmen der Erfindung vorgesehen, daß das Leitelement wenigstens gleich breit wie die ihm gegenüberliegende Bandbürste ausgebildet ist.It is advantageously provided in the context of the invention that the guide element is at least as wide as the band brush opposite it.

Das Umlenken der Borsten in die der Bandbürste zugekehrte Ebene der Glastafel erfolgt besonders schonend, wenn das Leitelement zur Bandbürste hin konvex gewölbt ist.The bristles are deflected particularly gently into the plane of the glass plate facing the band brush if the guide element is convexly curved towards the band brush.

Die Anpassung des Leitelementes an die jeweiligen Gegebeneheiten unter Berücksichtigung der Borstensteifheit und Borstenlänge ist besonders einfach, wenn die Neigung des Leitelementes zur Ebene der zu reinigenden Glastafeln durch Verschwenken des Leitelementes veränderbar ist, wobei die Schwenkachse vorzugsweise im Bereich des unteren Randes des Leitelementes vorgesehen ist.The adaptation of the guide element to the particular circumstances, taking into account the bristle rigidity and bristle length, is particularly simple if the inclination of the guide element to the plane of the glass panels to be cleaned can be changed by pivoting the guide element, the pivot axis preferably being provided in the region of the lower edge of the guide element.

Um die Lebensdauer des erfindungsgemäßen Leitelementes zu vergrößern und die Reibung der Borsten an diesem zu verkleinern, empfiehlt es sich im Rahmen der Erfindung, die der Bandbürste zugekehrte Fläche des Leitelementes mit einer reibungsvermindernden Oberflächenbeschichtung zu versehen, beispielsweise hartzuverchromen.In order to increase the service life of the guide element according to the invention and to reduce the friction of the bristles on it, it is recommended within the scope of the invention to provide the surface of the guide element facing the band brush with a friction-reducing surface coating, for example hard chrome plating.

Im Rahmen der Erfindung bewährt sich eine Ausführungsform, bei der das Leitelement über einen Schlitten an vertikalen Führungen zum Zustellen an den oberen Rand der zu reinigenden Glastafel verschiebbar gehaltert und mit einem Antrieb gekuppelt ist. Dadurch ist es möglich, das Leitwerk an verschieden hohe Glastafeln anzupassen, indem der untere Rand des Leitelementes unmittelbar über dem oberen Rand der Glastafel angeordnet wird.In the context of the invention, an embodiment has proven itself in which the guide element is slidably mounted on a slide on vertical guides for delivery to the upper edge of the glass sheet to be cleaned and is coupled to a drive. This makes it possible to adapt the tail unit to glass panels of different heights by arranging the lower edge of the guide element directly above the upper edge of the glass panel.

Zur Anpassung an verschieden dicke Glastafeln kann im Rahmen der Erfindung vorgesehen sein, daß das Leitelement vorzugsweise auf seinem Schlitten quer zur Förderebene der Glastafel verstellbar ist.To adapt to glass panels of different thicknesses, it can be provided within the scope of the invention that the guide element is preferably adjustable on its slide transversely to the conveying plane of the glass panel.

Das Zustellen des Leitelementes unmittelbar oberhalb des oberen horizontalen Randes der zu reinigenden Glastafel erfolgt besonders einfach, wenn der Antrieb zur vertikalen Bewegung des Leitelementes in Abhängigkeit von der durch ein Meßglied oder einen Schalter erfaßten Höhe der zu reinigenden Glastafel gesteuert ist. Dabei empfiehlt es sich, wenn der Schalter oder das Meßglied für das Erfassen der Höhe der zu reinigenden Glastafel mit dem Leitelement oder seinem Führungsschlitten starr verbunden ist.The delivery of the guide element immediately above the upper horizontal edge of the glass sheet to be cleaned is particularly simple if the drive for the vertical movement of the guide element is dependent on the height of the detected by a measuring element or a switch controlled glass panel to be cleaned. It is recommended if the switch or the measuring element for detecting the height of the glass sheet to be cleaned is rigidly connected to the guide element or its guide slide.

Gemäß einer bevorzugten Ausführungsform ist vorgesehen, daß als Antrieb für die Vertikalbewegungen des Leitelementes wenigstens ein Zahnriemen, eine Endloskette od. dgl. vorgesehen ist, dessen Trume im wesentlichen vertikal ausgerichtet sind, und der in Förderrichtung gesehen, vor dem Leitelement angeordnet ist und daß der den oberen Rand der Glasscheibe erfassende Schalter oder das Meßglied an einem der Trume des Zahnriemens, der Endloskette od. dgl. oder einer Verbindung zwischen dem Schlitten und dem Zahnriemen od. dgl. angeordnet ist. Diese Ausführungsform hat den Vorteil, daß die Größe (Höhe) der Glastafel erfaßt wird, bevor diese in den Bereich der Bandbürste bzw. des dieser gegenüberliegend angeordneten Leitelementes gelangt, so daß diese in die richtige Höhe bewegt werden kann, bevor noch die Glastafel den Bereich der Bandbürste erreicht hat.According to a preferred embodiment it is provided that at least one toothed belt, an endless chain or the like is provided as the drive for the vertical movements of the guide element, the strands of which are oriented substantially vertically and which, viewed in the conveying direction, is arranged in front of the guide element and that the upper edge of the glass pane-detecting switch or the measuring element on one of the runs of the toothed belt, the endless chain or the like. Or a connection between the carriage and the toothed belt or the like. Is arranged. This embodiment has the advantage that the size (height) of the glass sheet is detected before it reaches the area of the ribbon brush or the guide element arranged opposite it, so that it can be moved to the correct height before the glass sheet reaches the area the ribbon brush has reached.

Aus räumlichen Gründen empfiehlt es sich bei der erfindungsgemäßen Vorrichtung, soferne zwei oder mehrere Bandbürsten vorgesehen sind, die an einander gegenüberliegenden Flächen der zu reinigenden Glastafel angreifenden Bandbürsten ebenso wie die ihnen jeweils gegenüberliegenden Leitelemente, in Förderrichtung der Glastafel gesehen, zueinander versetzt anzuordnen. Diese Anordnung ergibt noch den Vorteil, daß die Führung der Glastafel, die ja vertikal stehend durch die Vorrichtung transportiert wird, durch der Bandbürste gegenüberliegend angeordnete schmale Stützrollen erfolgen kann.For spatial reasons, it is advisable in the device according to the invention, provided two or more ribbon brushes are provided, to arrange the ribbon brushes acting on opposite surfaces of the glass panel to be cleaned, as well as the guide elements opposite each other, as seen in the conveying direction of the glass panel. This arrangement also has the advantage that the glass sheet, which is transported vertically upright through the device, can be guided by the narrow brush rollers arranged opposite one another.

Weitere Einzelheiten der Erfindung ergeben sich aus der nachstehenden Beschreibung einer bevorzugten Ausführungsform. Es zeigt

  • Figur 1 schematisch eine Bandbürste, die dieser gegenüberliegend angeordneten Führungsrollen für eine Glastafel und ein Leitelement,
  • Figur 2 ein Leitelement in vergrößertem Maßstab,
  • Figur 3 weitgehend schematisiert in Seitenansicht ein Leitelement und
  • Figur 4 in Draufsicht Bandbürsten und die ihnen zugeordneten Leitelemente.
Further details of the invention result from the following description of a preferred embodiment. It shows
  • FIG. 1 schematically shows a ribbon brush, the guide rollers arranged opposite this for a glass sheet and a guide element,
  • FIG. 2 shows a guide element on an enlarged scale,
  • Figure 3 largely schematic side view of a guide element and
  • Figure 4 is a top view of belt brushes and the guide elements assigned to them.

Bevor die Ausführungsform im einzelnen beschrieben wird, ist darauf hinzuweisen, daß die Erfindung für Bandbürsten in den verschiedensten Ausführungsformen verwendbar ist. So kann die Erfindung, d. h. das Leitelement, bei einer Ausführungsform verwendet werden, bei welcher die Borsten unmittelbar an einem bandförmigen Träger der Bandbürste befestigt sind. Eine andere Möglichkeit für die Ausbildung der Bandbürsten besteht darin, daß die Borsten an mit gegebenenfalls streifenförmig ausgebildeten Trägern der Bandbürsten verbundenen Leisten vorgesehen sind. Die an den Bandbürsten vorgesehenen Borsten haben für gewöhnlich eine Länge von 3 bis 8 cm, vorzugsweise 4 cm.Before the embodiment is described in detail, it should be pointed out that the invention can be used for belt brushes in a wide variety of embodiments. Thus the invention, i. H. the guide element can be used in an embodiment in which the bristles are attached directly to a band-shaped carrier of the band brush. Another possibility for the formation of the band brushes is that the bristles are provided on strips connected to strips of the band brushes which may be strip-shaped. The bristles provided on the band brushes usually have a length of 3 to 8 cm, preferably 4 cm.

Obwohl in den Zeichnungen nicht dargestellt, besitzt die erfindungsgemäße Vorrichtung zum Reinigen von Glastafeln ein Gehäuse, in dem Ein-und Auslaßschlitze mit den entsprechenden Abdichtungen vorgesehen sind, durch welche die Glastafeln in das bzw. aus dem Gehäuse gefördert werden können. Im Gehäuse können neben den zur Reinigung bestimmten Bandbürsten noch Düsen zum Aufbringen von Spülmitteln und/oder Düsen zum Abblasen von Feuchtigkeit von den gereinigten Glastafeln vorgesehen sein.Although not shown in the drawings, the device according to the invention for cleaning glass panels has a housing in which inlet and outlet slots are provided with the corresponding seals, through which the glass panels can be conveyed into and out of the housing. In addition to the band brushes intended for cleaning, nozzles for applying detergents and / or nozzles for blowing off moisture from the cleaned glass plates can also be provided in the housing.

Eine in Figur 1 gezeigte Bandbürste 1 besteht aus einem Trägerband 2, an dem Borsten 3 befestigt sind. Das Trägerband 2, das beispielsweise ein endloses Kunststoffband sein kann, läuft über eine Antriebswalze 4 und eine Umlenkwalze 5 in Richtung der in Figur 1 eingezeichneten Pfeile um. Das sich nach unten bewegende Trum der Bandbürste 1 liegt mit seinen Borsten 3 an der der Bandbürste 1 zugekehrten Seite einer Glastafel 6 an, wobei die Borsten 3 (vgl. Fig. 2) wenigstens teilweise umgebogen und/oder schräg gestellt sind.A band brush 1 shown in FIG. 1 consists of a carrier band 2 to which bristles 3 are attached. The carrier tape 2, which can be an endless plastic tape, for example, runs over a drive roller 4 and a deflection roller 5 in the direction of the arrows shown in FIG. The downward-moving strand of the ribbon brush 1 lies with its bristles 3 on the side of a glass panel 6 facing the ribbon brush 1, the bristles 3 (cf. FIG. 2) being at least partially bent and / or inclined.

Die Glastafel 6 wird unten durch eine Fördervorrichtung 7 abgestützt, wobei die Fördervorrichtung 7 beispielsweise wie in Figur 3 gezeigt ausgebildet sein kann. Während die Fördervorrichtung 7 die Glastafel 6 von unten her abstützt und durch die Reinigungsvorrichtung bewegt, dienen an einem Maschinenbauteil 8 vorgesehene, frei drehbare Rollen 9 zur Abstützung der Glastafel 6 auf ihrer der Bandbürste 1 gegenüberliegenden Seite.The glass sheet 6 is supported at the bottom by a conveyor device 7, the conveyor device 7 being able to be designed, for example, as shown in FIG. 3. While the conveyor device 7 supports the glass sheet 6 from below and moves through the cleaning device, freely rotatable rollers 9 provided on a machine component 8 serve to support the glass sheet 6 on its side opposite the belt brush 1.

Innerhalb der Bandbürste 1 ist an deren Trägerband 2 anliegend eine Gleitplatte 10 vorgesehen, die den Zweck hat, die Bandbürste 1 im Bereich der Glastafel 6 gerade zu führen und gegen die Glastafel 6 zu drücken.Within the ribbon brush 1, a sliding plate 10 is provided adjacent to the carrier tape 2, which has the purpose of guiding the ribbon brush 1 straight in the region of the glass panel 6 and pressing it against the glass panel 6.

Oberhalb der Glastafel 6 ist in Figur 1 schematisch ein Leitelement 11 angedeutet, das durch Bewegen in Richtung der Doppelpfeile 12 und/oder 13 so auf den oberen Rand 14 der Glastafel 6 zugestellt werden kann, daß die Borsten 3, ohne den oberen Rand 14 bzw. die dort befindliche, der Bandbürste 1 zugekehrte Kante 16 der Glastafel 6 zu berühren, auf die Fläche 16' der Glastafel 6 gelangen. Dies ist in Einzelheiten in Figur 2 gezeigt. Aus Figur 2 ist ersichtlich, daß das Leitelement 11, das eine konvex gekrümmte Form besitzt, oberhalb der Glastafel 6 so angeordnet ist, daß der untere horizontale Rand 15 des Leitelementes 11 in der Ebene der Glasfläche 16' liegend unmittelbar oberhalb der Kante 16 des oberen Randes 14 der Glastafel 6 angeordnet ist. Um das Leitelement 11 in diese Lage bewegen zu können, ist es über einen Schlitten 17 an vertikalen Führungen 18 geführt und mit Hilfe wenigstens eines Druckmittelzylinders 19 in Richtung des Doppelpfeiles 13 so quer zur Ebene der Glastafel 6 verstellbar, daß sein unterer Rand 15 genau über der Kante 16 der Glastafel 6 zu liegen kommt. Zusätzlich ist das Leitelement 11 um eine Achse 20, die im Bereich seines unteren Randes 15 angeordnet ist, in Richtung des Doppelpfeiles 21 verschwenkbar, wozu ein Druckmittelmotor 22 vorgesehen ist.Above the glass panel 6, a guide element 11 is indicated schematically in FIG. 1, which can be moved onto the upper edge 14 of the glass panel 6 by moving in the direction of the double arrows 12 and / or 13 such that the bristles 3, without the upper edge 14 or to touch the edge 16 of the glass sheet 6 which is located there and faces the band brush 1, and reach the surface 16 'of the glass sheet 6. This is shown in detail in Figure 2. From Figure 2 it can be seen that the guide element 11, which has a convexly curved shape, is arranged above the glass sheet 6 so that the lower horizontal edge 15 of the guide element 11 lying in the plane of the glass surface 16 'immediately above the edge 16 of the upper Edge 14 of the glass sheet 6 is arranged. In order to be able to move the guide element 11 into this position, it is guided over a slide 17 on vertical guides 18 and, with the aid of at least one pressure medium cylinder 19 in the direction of the double arrow 13, can be adjusted transversely to the plane of the glass panel 6 in such a way that its lower edge 15 is accurate comes to rest over the edge 16 of the glass sheet 6. In addition, the guide element 11 can be pivoted about an axis 20, which is arranged in the region of its lower edge 15, in the direction of the double arrow 21, for which purpose a pressure medium motor 22 is provided.

Wie aus Figur 3 ersichtlich, ist der Schlitten 17 des Leitelementes 11, der an den Führungen 18 in Richtung des Doppelpfeiles 12 auf- und abbewegbar ist, mit endlosen Riemen, Zahnriemen, Ketten od. dgl. 23 gekuppelt, durch deren Betätigung über einen nicht gezeigten Antriebsmotor der Schlitten 17 und damit das Leitelement 11 gehoben oder gesenkt werden kann. Aus Figur 3 ist noch ersichtlich, daß am Verbindungsglied 24 zwischen dem Schlitten 17 und dem in Förderrichtung (Pfeil 25, Figur 3) gesehen vorderen Zahnriemen 23 od. dgl. ein Sensor 26 zum Erfassen des oberen Randes 14 der Glastafel 6 vorgesehen ist. Ausgelöst durch diesen Sensor 26, der als berührungslos ansprechender Schalter oder Rollenschalter, Lichtschranke od. dgl. ausgebildet sein kann, werden die Zahnriemen od. dgl. 23 betätigt und der untere Rand 15 des Leitelementes 11 auf den oberen Rand 14 der Glastafel 6 zugestellt. Am Verbindungsglied 27 kann ein weiterer Sensor 28 vorgesehen sein, der feststellt, wann die Glastafel 6 aus dem Bereich des Leitelementes 11 bzw. der diesem gegenüberliegenden Bandbürste 1 herausbewegt worden ist, worauf das Leitelement 11 beispielsweise in eine weiter oben liegende Ausgangslage angehoben werden kann.As can be seen from Figure 3, the carriage 17 of the guide element 11, which can be moved up and down on the guides 18 in the direction of the double arrow 12, is coupled to endless belts, toothed belts, chains or the like 23, by their actuation via one not Drive motor shown the carriage 17 and thus the guide element 11 can be raised or lowered. It can also be seen from FIG. 3 that a sensor 26 for detecting the upper edge 14 of the glass sheet 6 is provided on the connecting member 24 between the slide 17 and the front toothed belt 23 or the like seen in the conveying direction (arrow 25, FIG. 3). Triggered by this sensor 26, which can be designed as a non-contact responsive switch or roller switch, light barrier or the like, the toothed belts or the like 23 are actuated and the lower edge 15 of the guide element 11 is fed to the upper edge 14 of the glass sheet 6. A further sensor 28 can be provided on the connecting member 27, which detects when the glass sheet 6 has been moved out of the area of the guide element 11 or the band brush 1 opposite it, whereupon the guide element 11 can be raised, for example, to a starting position lying further up.

In Figur 3 ist eine bevorzugte Ausführungsform für eine die Glastafel 6 an ihrem unteren Rand abstützende und gleichzeitig durch die Vorrichtung fördernde Vorrichtung 7 gezeigt. Bei dieser Ausführungsform einer Fördervorrichtung 7 für Glastafeln 6 ist ein endlos umlaufendes Förderband vorgesehen, das beispielswiese als Gliederkette 30 ausgebildet ist und an dem Mitnehmer 31 um im wesentlichen horizontale Achsen 32 verschwenkbar gelagert sind. Die Mitnehmer 31 werden durch Gewichtsbelastung und/oder durch die Wirkung von Federn 33 in eine Stellung verschwenkt, in der ihr oberes Ende 34 über die Gliederkette 30 ragt. Zwischen jeweils zwei benachbarten Mitnehmern 31 sind beispielsweise aus Kunststoff bestehende Auflager 35 vorgesehen, auf welchen der untere Rand 36 der Glastafel 6 aufruht. Die im Bereich einer Glastafel 6 befindlichen Mitnehmer 31 werden von der Glastafel 6 nach unten gedrückt, wogegen der dem hinteren, vertikalen Rand 37 der Glastafel 6 zugeordnete Mitnehmer 31 nach oben verschwenkt ist und sich mit seinem oberen Ende 34 an den Rand 37 anlegt.FIG. 3 shows a preferred embodiment for a device 7 supporting the glass sheet 6 at its lower edge and at the same time conveying it through the device. In this embodiment of a conveyor device 7 for glass sheets 6, an endlessly revolving conveyor belt is provided which, for example, is designed as a link chain 30 and is mounted on the driver 31 so as to be pivotable about essentially horizontal axes 32. The drivers 31 are pivoted by weight loading and / or by the action of springs 33 into a position in which their upper end 34 protrudes over the link chain 30. Between two adjacent drivers 31, for example, plastic supports 35 are provided, on which the lower edge 36 of the glass sheet 6 rests. The drivers 31 located in the area of a glass sheet 6 are pressed downward by the glass sheet 6, whereas the driver 31 assigned to the rear, vertical edge 37 of the glass sheet 6 is pivoted upward and abuts the edge 37 with its upper end 34.

In Figur 4 ist noch gezeigt, wie die Bandbürsten 2 in Förderrichtung (Pfeil 25) ebenso gegeneinander versetzt sind wie die ihnen jeweils gegenüberliegenden Leitelemente 11.FIG. 4 also shows how the belt brushes 2 are offset from one another in the conveying direction (arrow 25), as are the guide elements 11 opposite them.
