Description

Die Erfindung geht aus von einer Vorrichtung mit den im Oberbegriff des Anspruchs 1 angegebenen Merkmalen. Eine solche Vorrichtung benötigt man in einer Isolierglas-Zusammenbaulinie. Die Vorrichtung schließt an eine Waschmaschine an, in welcher die Glastafeln im Durchlauf gewaschen werden. Sie laufen anschließend in die Trocknungsvorrichtung ein, in welcher sie ebenfalls im Durchlauf getrocknet werden. Häufig sind die Trocknungsvorrichtung und die Waschmaschine zu einer Baueinheit zusammengefaßt.The invention relates to a device with the features specified in the preamble of claim 1. Such a device is required in an insulating glass assembly line. The device connects to a washing machine in which the glass sheets are washed in a continuous process. They then run into the drying device, in which they are also dried continuously. The drying device and the washing machine are often combined to form one structural unit.

Die bekannten Trocknungsvorrichtungen haben einen Waagerechtförderer, auf welchem die GIcEtafeln stehend durch die Vorrichtung hindurchbewegt werden. Dabei werden die Glastafeln über eine ihrer beiden Großflächen abgestützt; bei den dazu verwendeten Stützelementen handelt es sich im allgemeinen um freilaufende Rollen mit quer zur Laufrichtung des Waagerechtförderers angeordneten Achsen. Diese Rollen definieren mit ihrer Lauffläche gemeinsam eine Ebene , die nachfolgend als Glastafellaufebene bezeichnet wird; es ist jene Ebene, in welcher die Glastafeln mit ihrer Großfläche, an welcher die Rollen angreifen, liegen. Die Glastafellaufebene ist eine durch die Stützelemente fest vorgegebene Ebene in der Trocknungsvorrichtung. Der Waagerechtförderer und die Stützelemente sind in einem Gehäuse untergebracht, wobei in den beiden die Laufrichtung des waagerechtfördererskreuzenden Stirnwänden für das Zuführen und Abfördern der Glastafeln ein Einlaufschlitz und ein Auslaufschlitz vorgesehen sind, welche in der Flucht der Glastafellaufebene liegen.The known drying devices have a horizontal conveyor, on which the glazed sheets are moved standing through the device. The glass panels are supported over one of their two large areas; the supporting elements used for this purpose are generally free-running rollers with axes arranged transversely to the running direction of the horizontal conveyor. Together with their running surface, these rollers define a level, which is referred to below as the glass panel running level; it is the level in which the large-area glass panels on which the rollers engage lie. The glass panel running level is a level predetermined by the support elements in the drying device. The horizontal conveyor and the support elements are housed in one housing, with the barrel in the two Direction of the horizontal conveyor crossing end walls for the supply and removal of the glass sheets, an inlet slot and an outlet slot are provided, which are in alignment with the glass sheet running level.

Ausserdem befinden sich in dem Gehäuse zwei langgestreckte Blasdüsen, nämlich eine vor der Glastafellaufebene und eine dahinter. Die Luftaustrittsschlitze der Blasdüse verlaufen im wesentlichen parallel zu Glastafellaufebene und erstrecken sich ausgehend vom Aufstellförderer, auf welchem die Glastafeln stehen, gegen die Förderrichtung geneigt schräg nach oben. Ausserdem sind die Blasdüsen so ausgerichtet, dass sie ihren Luftstrom entgegen der Förderrichtung schräg gegen die Glastafellaufebene richten. Auf diese Weise beaufschlagen die Blasdüsen die Glastafeln als erstes im Bereich der vorderen oberen Ecke und dann über die Glasfläche fortschreitend längs einer geneigten Front, welche durch die Neigung der Blasdüsen bestimmt ist, bis hin zur hinteren unteren Ecke der Glastafel, welche als letztes getrocknet wird. Auf der Glastafel befindliche Wassertröpfchen werden auf diese Weise durch den Luftstrom entgegen der Laufrichtung der Glastafel schräg nach unten geblasen. Damit die feuchte Luftströmung nicht jenen Teil der Glastafel treffen kann, welcher die beiden Blasdüsen bereits passiert hat, ist zwischen den Blasdüsen und der benachbarten Gehäusevorderwand und Gehäuserückwand jeweils eine Abschirmung vorgesehen, beispielsweise eine Gummilippe, welche einerseits längs der Blasdüse auf dieser befestigt ist und mit ihrem anderen Längsrand der Gehäusevorderwand bzw. der Gehäuserückwand anliegt.In addition, there are two elongated blowing nozzles in the housing, namely one in front of the glass panel running level and one behind. The air outlet slots of the blower nozzle run essentially parallel to the glass sheet running plane and, starting from the installation conveyor on which the glass sheets are placed, extend obliquely upwards at an angle to the conveying direction. In addition, the blow nozzles are aligned in such a way that they direct their air flow against the direction of conveyance at an angle against the glass panel running level. In this way, the blowing nozzles first act on the glass panels in the area of the front upper corner and then progressively over the glass surface along an inclined front, which is determined by the inclination of the blowing nozzles, up to the rear lower corner of the glass panel, which is dried last . In this way, water droplets on the glass sheet are blown obliquely downwards by the air flow against the direction of travel of the glass sheet. So that the moist air flow cannot hit that part of the glass sheet that has already passed the two blowing nozzles, a shield is provided between the blowing nozzles and the adjacent front and rear walls of the housing, for example a rubber lip, which is attached to the blowing nozzle on the one hand and with it the other longitudinal edge of the housing front wall or the rear wall of the housing.

Die aus den Blasdüsen austretende Luft muss das Gehäuse der Vorrichtung wieder verlassen können. An der Gehäuseunterseite ist das nicht möglich, weil sich dort der Aufstellförderer und eine Auffangwanne für das Wasser befinden. In Förderrichtung darf und kann die Abluft das Gehäuse nicht verlassen, weil es dort die getrockneten Glastafeln wieder befeuchten würde. Entgegen der Förderrichtung kann die Abluft das Gehäuse nicht verlasen, weil sich dort die Waschmaschine befindet. Zur Vorderseite des Gehäuses will man die Abluft nicht herausführen, weil dort das Bedienungspersonal angeblasen würde und weil man die Vorderseite nach Möglichkeit großflächig verglast, um den Trocknungsvorgang jederzeit beobachten und kontrollieren zu können. Durch die obere Gehäusewand kann man bei den bekannten Trocknungsvorrichtungen die Abluft nicht hindurchführen, weil dort keine Möglichkeit besteht, eine Abluftöffnung vorzusehen; bei den bekannten Vorrichtungen enden die Blasdüsen nämlich dicht vor der einlaufseitigen Gehäusewand, sodass zwischen dem oberen Ende beiden Blasdüsen und der einlaufseitigen Stirnwand praktisch kein Raum mehr ist für eine Abluftöffnung, zumal die Luftzufuhrrohre für die beiden Blasdüsen, die einigen Platz beanspruchen, an dieser Stelle von oben her in die Blasdüsen einmünden. In dem an das obere Ende der Blasdüsen in Förderrichtung anschließenden Bereich der Gehäuseoberseite kann man eine Abluftöffnung nicht vorsehen, weil der darunter liegende Teil des Innenraums des Gehäuses der durch die Abschirmungen vom einlaufseitigen nassen Bereich getrennte trockene Bereich der Vorrichtung ist, in welchen der Luftstrom nicht eindringt und auch nicht eindringen soll. Bei den bekannten Vorrichtungen hat man deshalb durch Ausbuchtung der Rückwand einen von unten nach oben verlaufenden Abluftkamin gebildet. In diesen Abluftkamin kann die aus der hinteren Blasdüse austretende Luft ohne Schwierigkeit eintreten. Nachteilig bei den bekannten Vorrichtungen ist, dass die aus der vorderen Blasdüse austretende Luft einen erschwerten Zugang zum Abluftkamin hat, denn diese Luft, welche zunächst schräg nach unten gerichtet aus der Blasdüse austritt, muss umgelenkt und über den oberen Glastafelrand hinweg in den hinteren Bereich des Gehäuses geleitet werden. Dies bereitet umsogrößere Schwierigkeiten, je höher die zu trocknenden Glastafeln sind, weil mit zunehmender Glastafelhöhe der durch die einlaufseitige Gehäusestirnwand, durch die Gehäuseoberseite, durch die Blasdüsen und durch den oberen Glastafelrand begrenzte Durchtrittsquerschnitt für die vom Raum vor der Glastafel in den Raum hinter der Glastafel strömende Luft zunehmend kleiner wird. Die Folge davon ist, dass sich hohe Glastafeln wesentlich schlechter trocknen lassen als kleine Glastafen, sodass man für hohe Glastafeln erheblich längere Trockenzeiten benötigt.The air emerging from the blow nozzles must be able to leave the housing of the device again. This is not possible on the underside of the housing, because the installation conveyor and a collecting tray for the water are located there. In the conveying direction, the exhaust air must not and cannot leave the housing because it would moisten the dried glass panels there again. Contrary to the conveying direction, the exhaust air cannot leave the housing because the washing machine is located there. The exhaust air does not want to be led out to the front of the housing because the operating personnel would be blown there and because the front side should be glazed over a large area, so that the drying process can be monitored and controlled at any time. In the known drying devices, the exhaust air cannot be passed through the upper housing wall because there is no possibility of providing an exhaust air opening; In the known devices, the blowing nozzles end precisely in front of the inlet-side housing wall, so that there is practically no space between the upper end of the two blowing nozzles and the inlet-side end wall for an exhaust air opening, especially since the air supply pipes for the two blowing nozzles, which take up a lot of space, at this point Open into the blow nozzles from above. In the area of the top of the housing adjoining the upper end of the blowing nozzles in the conveying direction, an exhaust air opening cannot be provided because of the underneath lying part of the interior of the housing is the dry area of the device which is separated from the inlet-side wet area by the shields and into which the air flow does not penetrate and should not penetrate. In the known devices, therefore, an exhaust air chimney running from bottom to top has been formed by bulging the rear wall. The air emerging from the rear blowing nozzle can enter this exhaust air chimney without difficulty. A disadvantage of the known devices is that the air emerging from the front blow nozzle has a difficult access to the exhaust air chimney, because this air, which initially emerges obliquely downward from the blow nozzle, must be deflected and over the upper edge of the glass panel into the rear area of the Housing are directed. This is all the more difficult the higher the glass sheets to be dried, because as the glass sheet height increases, the passage cross-section for those from the room in front of the glass sheet into the room behind the glass sheet increases due to the inlet end wall, the top of the housing, the blowing nozzles and the upper edge of the glass sheet flowing air becomes increasingly smaller. The consequence of this is that tall glass panels are much more difficult to dry than small glass panels, so that significantly longer drying times are required for tall glass panels.

Der Erfindung liegt die Aufgabe zugrunde, eine verbesserte Vorrichtung der eingangs genannten Art zu schaffen, welche insbesondere hohe Glastafeln rascher und gründlicher zu trocknen vermag.The invention has for its object to provide an improved device of the type mentioned, which Especially tall glass panels can dry faster and more thoroughly.

Diese Aufgabe wird gelöst durch eine Vorrichtung mit den im Anspruch 1 angegebenen Merkmalen. Eine auf demselben Lösungsprinzip beruhende zweite Lösung dieser Aufgabe ist Gegenstand des unabhängigen Anspruches 5. Vorteilhafte Weiterbildungen der Erfindung sind Gegenstand der Unteransprüche.This object is achieved by a device with the features specified in claim 1. A second solution to this problem based on the same solution principle is the subject of independent claim 5. Advantageous developments of the invention are the subject of the subclaims.

Die erste erfindungsgemäße Lösung unterscheidet sich vom Stand der Technik dadurch, dass das obere Ende der Blasdüsen nicht bis dicht vor die einlaufseitige Stirnwand des Gehäuses geführt ist, sondern in einigem Abstand davon angeordnet ist, der wesentlich größer ist als der für den Einbau und die Montage im Gehäuse nötige Minimalabstand. Dieser vergrößerte Astand, welcher vorzugsweise wenigstens 20 cm, insbesondere 30 bis 50 cm beträgt, wird erfindungsgemäß dazu benutzt, zwischen dem oberen Ende der Düsen und der einlaufseitigen Stirnwand in der Gehäuseoberseite die Abluftöffnung vorzusehen, welche vorzugsweise den gesamten Bereich zwischen der einlaufseitigen Gehäusestirnwand und dem oberen Ende der Blasdüsen in Längsrichtung und Querrichtung überdeckt.The first solution according to the invention differs from the prior art in that the upper end of the blowing nozzles is not guided close to the inlet-side end wall of the housing, but is arranged at a distance therefrom which is considerably larger than that for installation and assembly minimum distance required in the housing. This enlarged spacing, which is preferably at least 20 cm, in particular 30 to 50 cm, is used according to the invention to provide the exhaust air opening between the upper end of the nozzles and the inlet-side end wall in the top of the housing, which preferably covers the entire area between the inlet-side housing end wall and the upper end of the blowing nozzles covered in the longitudinal and transverse directions.

Durch die Erfindung wird erreicht, dass die aus der vorderen Blasdüse austretende Luft genauso leicht wie die aus der hinteren Blasdüse austretende Luft die oben liegende Abluftöffnung erreichen kann und dazu nicht mehr einen Weg über den oberen Rand der Glastafeln in den rückseitigen Raum des Gehäuses nehmen muss, welcher beim Stand der Technik durch große Scheiben obendrein nahezu blockiert wurde. Ausserdem wird durch die Erfindung die/bekannten Trocknungsvorrichtungen beim Trocknen hoher Glastafeln zwangsläufig auftretende starke Wirbelbildung im Raum auf der Glastafelvorderseite weitgehend vermieden, weil der Abluft die Möglichkeit gegeben ist, auch aus dem Raum an der Glastafelvorderseite ungehindert zu entweichen.It is achieved by the invention that the air emerging from the front blowing nozzle is as light as that from the Air emerging from the rear blowing nozzle can reach the exhaust air opening at the top and no longer has to take a path over the upper edge of the glass panels into the rear space of the housing, which, in the prior art, was almost blocked by large panes. In addition, the / known drying devices during the drying of tall glass panels largely avoid strong vortex formation in the room on the glass panel front side, because the exhaust air is given the opportunity to escape unhindered from the room on the glass panel front.

Die erste erfindungsgemäße Lösung hat zur Folge, dass die Trocknungsvorrichtung gegenüber bekannten Trocknunsvorrichtungen entsprechend der Bemessung der oben angeordneten Abluftöffnung vergrößert ist. Der dadurch bedingte Mehraufwand wird jedoch durch die verbesserte Trocknungswirkung und die dadurch mögliche Verkürzung der Trockenzeiten mehr als ausgeglichen.The result of the first solution according to the invention is that the drying device is enlarged compared to known drying devices in accordance with the dimensioning of the exhaust air opening arranged at the top. The resulting additional effort is more than offset by the improved drying effect and the resulting reduction in drying times.

Die zweite erfindungsgemäße Lösung der gestellten Aufgabe erfordert hingegen keine Verlängerung der Trocknungsvorrichtung im Vergleich zu bekannten Vorrichtungen, dennsie sieht einen Abluftschacht vor, welcher gegenüber dem oberen Ende der Blasdüsen in Förderrichtung vorverlegt ist. Damit trotzdem sichergestellt ist, dass die feuchte Abluft nicht an jenem Teil der-Glastafeln entlangstreicht, welcher die beiden Blasdüsen bereits passiert hat, ist erfindungsgemäß vorgesehen, dass die von den Blasdüsen ausgehende und sich bis zu den benachbarten Gehäusewänden erstreckende Abschirmung die jeweilige angrenzende Gehäusewand nur bis zu einer vorgegebenen Höhe längs einer ungefähr zur Blasdüse parallelen Linie berührt, wie es auch bei bekannten Vorrichtungen der Fall ist, ab dieser vorgegebenen Höhe - anders als beim Stand der Technik - die Gehäusewand jedoch längs einer steileren, insbesondere längs einer senkrechten Linie berührt und dadurch einen nach oben führenden Schacht begrenzt durch welchen die Abluft von beiden Seiten der Glastafeln gleichermaßen ungehindert zu einer in der Gehäuseoberseite vorgesehenen Abluftöffnung gelangen und entweichen können. Vorzugsweise ist der öffnungsquerschnitt der Abluftöffnung ungefähr genau so groß wie der Querschnitt des auf diese Weise gebildeten Abluftschachtes; insbesondere erstreckt sich die Abluftöffnung vorzugsweise über die gesamte Breite des Gehäuses; für die Bemessung der Länge der Abluftöffnung gilt dabei im Prinzip dasselbe wie bei der ersten erfindungsgemäßen Lösung, sie sollte nämlich wenigstens 20 cm, vorzugsweise 30 bis 50 cm betragen. Führen - was bevorzugt wird - die in das obere Ende der Blasdüsen einmündenden Luftzufuhrrohre durch die Abluftbffnung hindurch in das Gehäuse hinein, dann ist die Abluftöffnung entsprechend größer zu dimensionieren, sie ist näherungsweise um den Durchmesser der Luftzufuhrrohre zu verlängern.The second inventive solution to the problem, however, does not require an extension of the drying device compared to known devices, because it provides an exhaust duct which is advanced in the conveying direction relative to the upper end of the blowing nozzles. So that it is still ensured that the moist exhaust air does not sweep along that part of the glass panels which the two blowing nozzles has already passed, it is provided according to the invention that the shielding extending from the blowing nozzles and extending to the adjacent housing walls only touches the respective adjacent housing wall up to a predetermined height along a line approximately parallel to the blowing nozzle, as is also the case with known ones Devices are the case, from this predetermined height - unlike in the prior art - but touches the housing wall along a steeper, in particular along a vertical line and thereby delimits an upwardly leading shaft through which the exhaust air from both sides of the glass panels is equally unhindered an exhaust air opening provided in the top of the housing can escape and escape. The opening cross section of the exhaust air opening is preferably approximately as large as the cross section of the exhaust air duct formed in this way; in particular, the exhaust air opening preferably extends over the entire width of the housing; For the dimensioning of the length of the exhaust air opening, the same principle applies as for the first solution according to the invention, namely it should be at least 20 cm, preferably 30 to 50 cm. If - which is preferred - the air supply pipes leading into the upper end of the blow nozzles lead through the exhaust air opening into the housing, then the exhaust air opening is to be dimensioned correspondingly larger, it is approximately to be extended by the diameter of the air supply pipes.

Beiden angegebenen Lösungen ist gemeinsam, dass durch sie im oberen, einlaufseitigen Bereich des Gehäuses der Trocknungsvorrichtung ein hinreichend dimensionierter Abluftschacht gebildet wird, welcher in eine in der Gehäuseoberseite liegende Abluftöffnung mündet und von beiden Seiten der Glastafeln eine gleich gute Abfuhr der Abluft ermöglicht. In beiden Fällen ist die Trocknungswirkung gegenüber bekannten Trocknungsvorrichtungen erheblich verbessert und ermöglicht eine deutliche Verringerung der Trocknungszeiten.Both of the solutions given have in common that they form an adequately dimensioned exhaust duct in the upper, inlet-side area of the housing of the drying device, which opens into an exhaust air opening in the top of the housing and enables equally good removal of the exhaust air from both sides of the glass panels. In both cases, the drying effect is significantly improved compared to known drying devices and enables a significant reduction in drying times.

Zwei Ausführungsbeispiele der Erfindung sind schematisch in den beigefügten Zeichnungen dargestellt und werden nachstehend beschrieben.Two embodiments of the invention are shown schematically in the accompanying drawings and are described below.

Die Figuren 1 und 2 zeigen in Förderrichtung 7 aufeinanderfolgend angeordnet eine Glastafelwaschmaschine 10 und eine Trocknungsvorrichtung 11. In der Waschmaschine befinden sich zwei Reihen von Wellen 1 und 1a parallel zueinander und mit annähernd lotrechten, ein wenig nach hinten geneigten Achsen. Die Wellen 1 und 1a tragen über ihre Länge verteilt einige Rollen 2 bzw. 2a, welche drehfest auf den Wellen 1 bzw. 1a angeordnet sind. Die Laufflächen der Rollen 2a der hinteren Wellen sind so angeordnet, dass sie auf ihrer Vorderseite eine gemeinsame Tangentialebene 6 haben, welche hier als Glastafellaufebene bezeichnet wird. Glastafeln 5, welche durch die Waschmaschine geführt werden, lehnen sich mit ihrer hinteren Großfläche, welche mit der Glastafellaufebene zusammenfällt, gegen die hinteren Rollen 2a an. Mit ihrem unteren Rand stehen die Glastafeln 5 auf einer waagerechten Zeile von Tragrollen 4, deren Drehachsen senkrecht zur Glastafellaufebene verlaufen.FIGS. 1 and 2 show a glass sheet washing machine 10 and a drying device 11 arranged in succession in the conveying direction 7. In the washing machine there are two rows of shafts 1 and 1a parallel to one another and with approximately perpendicular axes which are inclined slightly to the rear. The shafts 1 and 1a carry a number of rollers 2 and 2a distributed over their length, which are arranged in a rotationally fixed manner on the shafts 1 and 1a. The running surfaces of the rollers 2a of the rear shafts are arranged such that they have a common tangential plane 6 on their front side, which is referred to here as the glass sheet running plane. Glass panels 5, which are guided through the washing machine, lean against the rear rollers 2a with their large rear surface, which coincides with the glass panel running level. With its lower edge, the glass panels 5 stand on a horizontal line of support rollers 4, the axes of rotation of which are perpendicular to the glass panel running plane.

Zum Reinigen der Glastafeln 5 ist die Waschmaschine mit Paaren von Bürstwalzen 8 und 8a, 9 und 9a ausgerüstet, deren Achsen zu den Wellen 1 und 1a parallel verlaufen und welche getrennt von den Wellen 1 und 1a und getrennt von den Tragrollen 4 einzeln durch Motoren 19 antreibbar sind, welche gestellfest oberhalb der Bürstwalzen angeordnet sind.To clean the glass panels 5, the washing machine is equipped with pairs of brushing rollers 8 and 8a, 9 and 9a, the axes of which run parallel to the shafts 1 and 1a and which are separate from the shafts 1 and 1a and separated can be driven individually by the support rollers 4 by motors 19, which are arranged fixed to the frame above the brush rollers.

Die Wellen 1 und 1a sowie die Tragrollen 4 sind untereinander synchron antreibbar; sie bilden gemeinsam einen Waagerechtförderer, durch welchen die Glastafeln 5 durch die Waschmaschine 10 gefördert werden. Der Waagerechtförderer setzt sich fort in den Bereich der Trocknungs- ` vorrichtung 11, welche ebenfalls eine waagerechte Zeile von Tragrollen 4 hat, deren Drehachsen senkrecht zur Glastafellaufebene 6 verlaufen und welche höhengleich mit den entsprechenden Tragrollen 4 in der Waschmaschine 10 angeordnet und synchron mit diesen antreibbar sind. Zum Abstützen der Glastafeln 5 über ihre hintere Großfläche ist in der Trocknungsvorrichtung 11 oberhalb des durch die Tragrollen 4 gebildeten Aufstellförderers ein Stützrollenfeld vorgesehen, welches aus gestellfest angeordneten, freilaufenden Rollen 25 besteht, deren Drehachsen parallel zur Glastafellaufebene 6 senkrecht zur Förderrichtung 7 verlaufen. Im gezeichneten Beispiel sind die Rollen 25 teils an waagerechten Streben 26, teils an einer vertikalen Strebe 27 und teils an einer schräg verlaufenden Strebe 28 befestigt. Die schräg verlaufende Strebe 28 ist am Körper der hinteren von zwei langgestreckten Blasdüsen 29 und 30 befestigt, von denen die vordere Blasdüse 29 vor der Glastafellaufebene und die hintere Blasdüse 30 hinter der Glastafellaufebene 6 angeordnet ist. Die beiden Blasdüsen 29 und 30 verlaufen parallel zueinander und zur Glastafellaufebene 6, erstrecken sich von den Tragrollen 4 hinauf bis in eine Höhe,die etwas größer ist als die größte zu trocknende Glastafel; praktisch bedeutet das, dass das obere Ende der Blasdüsen 29 und 30 etwas höher liegt, als das obere Ende der Bürstwalzen 8 und 9 in der voraufgehenden Waschmaschine 10. Nicht weit oberhalb des oberen Endes der Blasdüsen verläuft die Gehäuseoberseite 31. Die Blasdüsen sind gegen die Förderrichtung 7 geneigt angeordnet und ihre Luftaustrittsöffnungen 29a und 30a sind so ausgerichtet, dass der Luftstrom auf die Glastafeln nicht senkrecht, sondern der Förderrichtung 7 schräg entgegengerichtet auftrifft.The shafts 1 and 1a and the support rollers 4 can be driven synchronously with one another; together they form a horizontal conveyor through which the glass sheets 5 are conveyed through the washing machine 10. The horizontal conveyor continues in the area of the drying device 11, which also has a horizontal line of support rollers 4, the axes of rotation of which run perpendicular to the glass plate running plane 6 and which are arranged at the same height as the corresponding support rollers 4 in the washing machine 10 and can be driven synchronously with them are. To support the glass sheets 5 over their large rear surface, a support roller field is provided in the drying device 11 above the stand-up conveyor formed by the support rollers 4, which consists of free-running rollers 25 arranged fixed to the frame, the axes of rotation of which run parallel to the direction of conveyance 7 parallel to the glass panel running plane 6. In the example shown, the rollers 25 are attached partly to horizontal struts 26, partly to a vertical strut 27 and partly to an oblique strut 28. The oblique strut 28 is attached to the body of the rear of two elongated blow nozzles 29 and 30, of which the front blow nozzle 29 in front of the glass panel running plane and the rear blow nozzle 30 behind the glass table running level 6 is arranged. The two blowing nozzles 29 and 30 run parallel to one another and to the glass sheet running plane 6, extend from the support rollers 4 up to a height which is somewhat larger than the largest glass sheet to be dried; In practical terms, this means that the upper end of the blowing nozzles 29 and 30 is slightly higher than the upper end of the brushing rollers 8 and 9 in the previous washing machine 10. The upper side of the housing 31 does not run far above the upper end of the blowing nozzles. The blowing nozzles are against the The conveying direction 7 is arranged at an incline and its air outlet openings 29a and 30a are oriented such that the air flow does not hit the glass panels perpendicularly, but rather in an opposite direction to the conveying direction 7.

Auf den der Glastafellaufebene 6 abgewandten Seiten der Blasdüsen 29 und 30 ist jeweils eine Abschirmung 32 und 33 befestigt, welche sich über die volle Länge der Düsen erstreckt und bis zu den angrenzenden Gehäusewänden, nämlich bis zur Rückwand 34 bzw. bis zur Vorderwand 35 reicht. Bei den Abschirmungen 32 und 33 handelt es sich um breite Gummilippen, welche in Förderrichtung 7 konvex gewölbt sind und der Rückwand 34 sowie der vorderen Wand 35 bedingt durch die Gummielastiz-ität mit leichtem Andruck anliegen. Die Gummilippen unterteilen den Innenraum des Gehäuses der Trocknungsvorrichtung in einen ersten Bereich 36, in welchendie Blasluft eintritt, und in einen zweiten Bereich 37, welcher demgegenüber abgeschirmt ist.On the sides of the blowing nozzles 29 and 30 facing away from the glass panel running level 6, a shield 32 and 33 is attached, which extends over the full length of the nozzles and extends to the adjacent housing walls, namely to the rear wall 34 and to the front wall 35. The shields 32 and 33 are wide rubber lips which are convexly curved in the conveying direction 7 and which bear against the rear wall 34 and the front wall 35 due to the rubber elasticity with slight pressure. The rubber lips divide the interior of the housing of the drying device into a first area 36, into which the blowing air enters, and into a second area 37, which is shielded from it.

Die eingeblasene Luft erzeugt im ersten Bereich 36 einen Überdruck. durch welchen die Gummilippen 32 und 33 mit zusätzlichem Druck gegen die Gehäuserückwand 34 bzw. die vordere Wand 35 des Gehäuses gedrückt werden. Die Gummilippen verhindern, dass die mit Feuchtigkeit beladene Luft aus dem ersten Bereich 36 in den zweiten Bereich 37 gelangt und den dort befindlichen Teil der Glastafel 5, welcher die Blasdüsen 29 und 30 bereits passiert hat, erneut befeuchtet. Die aus den Blasdüsen ausströmende Luft ist zunächst schräg nach unten gerichtet und treibt dabei an der Glastafel 5 befindliche Wassertröpfchen nach unten; sie wird dann nach oben umgelenkt und gelangt durch eine in der Gehäuseoberseite 31 vorgesehene Abluftöffnung 38 ins Freie. Die Abluftöffnung erstreckt sich einerseits praktisch über die gesamte Breite der Gehäuseoberseite 31 und andererseits in Förderrichtung 7 von der einlaufseitigen Gehäusestirnwand 39 ungefähr bis zum oberen Ende der Blasdüsen 29 und 30, genau genommen bis zu deren Flucht, vorzugsweise über eine Länge zwischen 30 und 50 cm. Dadurch ist gewährleistet, dass sowohl von der Vorderseite als auch von der Rückseite einer Glastafel 5 auch bei sehr hohen Glastafeln die Abluft rasch und ohne größere Wirbelbildung nach oben entweichen kann.The air blown in creates an overpressure in the first region 36. through which the rubber lips 32 and 33 are pressed with additional pressure against the rear wall 34 and the front wall 35 of the housing. The rubber lips prevent the moisture-laden air from the first region 36 from reaching the second region 37 and moistening the part of the glass sheet 5 which has already passed through the blowing nozzles 29 and 30. The air flowing out of the blowing nozzles is initially directed obliquely downward and in doing so drives water droplets located on the glass sheet 5 downward; it is then deflected upwards and passes through an exhaust air opening 38 provided in the upper side 31 of the housing to the outside. The exhaust air opening extends on the one hand practically over the entire width of the housing top 31 and on the other hand in the conveying direction 7 from the inlet-side housing end wall 39 approximately to the upper end of the blowing nozzles 29 and 30, strictly speaking until they escape, preferably over a length between 30 and 50 cm . This ensures that the exhaust air can escape quickly from the front as well as from the back of a glass sheet 5, even with very high glass sheets, and without major eddy formation.

Für das Zufördern und Abfördern der Glastafeln 5 ist in der einlaufseitigen Gehäusewand 39 ein Einlaufschlitz 40 und in der auslaufseitigen Gehäusestirnwand 41 ein Auslaufschlitz 42 vorgesehen; beide Schlitze verlaufen in der Flucht der Glastafellaufebene 6.For the feeding and removal of the glass sheets 5, an inlet slot 40 is provided in the inlet-side housing wall 39 and an outlet slot 42 in the outlet-side housing end wall 41; both slots run in the Escape the glass panel running level 6.

Die Luftzufuhr zu den Blasdüsen 29 und 30 erfolgt über zwei Rohre 43 und 44, welche von oben her in dem (in Förderrichtung 7 gesehen) an die Abluftöffnung 38 unmittelbar anschließenden Bereich durch die Gehäuseoberseite 31 in das Gehäuse hineinführen und in das obere Ende der jeweiligen Blasdüse 29 bzw. 30 einmünden.The air supply to the blowing nozzles 29 and 30 takes place via two pipes 43 and 44, which lead from above into the area (seen in the conveying direction 7) immediately after the exhaust air opening 38 through the housing top 31 into the housing and into the upper end of the respective Open the blow nozzle 29 or 30.

Anhand der Fig. 3 erkennt man noch, dass die Gehäuse- . vorderwand überwiegend durch eine großflächige, verglaste Tür gebildet wird, welche eine Kontrolle des Trocknungsvorganges ermöglicht.3 that the housing . front wall is mainly formed by a large, glazed door, which enables control of the drying process.

Das in den Figuren 4 und 5 dargestellte zweite Ausführungsbeispiel stimmt in vielen Teilen mit dem ersten Ausführungsbeispiel überein. Gleiche oder einander entsprechende Bauteile sind deshalb mit übereinstimmenden Bezugszahlen bezeichnet. Die nachfolgende Beschreibung beschränkt sich im wesentlichen auf die Unterschiede des zweiten Ausführungsbeispieles gegenüber dem ersten Ausführungsbeispiel.The second exemplary embodiment shown in FIGS. 4 and 5 corresponds in many parts to the first exemplary embodiment. The same or corresponding components are therefore designated by the same reference numerals. The following description is essentially limited to the differences between the second exemplary embodiment and the first exemplary embodiment.

Ein erster Unterschied, welcher für die Erfindung aber ohne Bedeutung ist, liegt darin, dass die Waschmaschine 10 und die Trocknungsvorrichtung/in einem gemeinsamen Gehäuse zusammengefaßt sind.A first difference, which is of no importance for the invention, lies in the fact that the washing machine 10 and the drying device / are combined in a common housing.

Der wesentliche Unterschied zwischen den beiden Ausführungsbeispielen besteht jedoch darin, dass die Trocknungsvorrichtung im zweiten Ausführungsbeispiel kürzer ist als im ersten Ausführungsbeispiel. Dies wird dadurch erreicht, dass das obere Ende der Blasdüsen 29 und 30 in wesentlich geringerem Abstand vor der einlaufseitigen Gehäusewand 39 endet als im ersten Ausführungsbeispiel. Weil dann jedoch der Platz zwischen dem oberen Ende der Blasdüsen und der einlaufseitigen Gehäusewand 39 nicht mehr ausreicht, um in der Gehäuseoberseite 31 an dieser Stelle eine hinreichend große Abluftöffnung vorzusehen, ist die Abluftöffnung 38 im zweiten Ausführungsbeispiel in Förderrichtung 7 gesehen über das obere Ende der Blasdüsen 29 und 30 hinaus ausgedehnt. Dies war möglich, ohne die Abschirmung zwischen dem ersten, feuchten Bereich 36 und dem zweiten, trockenen Bereich 37 der Vorrichtung aufzuheben,durch eine geänderte Ausbildung der Abschirmungen: Bis zu einer vorgegebenen Höhe H sind die Abschirmungen 33 und 34 nach wie vor so angeordnet und geführt wie im ersten Ausführungsbeispiel. Ab dieser vorgegebenen Höhe H jedoch verlaufen die Gummilippen senkrecht an der Gehäuserückwand 34 und an der vorderen Gehäusewand 35 nach oben und sind mit ihrem weiter in der Gehäusemitte liegenden Längsrand jeweils an einer in der Ansicht gemäß Fig. 4 dreieckig geformten Zwischenwand 45 befestigt, welche mit ihrem einlaufseitigen Rand 46 an der Aussenseite der jeweiligen Düse befestigt ist, sich in Förderrichtung 7 - vorzugsweise parallel zur Glastafellaufebene 6 - erstreckt und an ihrem auslaufseitigen Rand 47 mit der Gummilippe verbunden ist.The main difference between the two Aus However, exemplary embodiments consist in the fact that the drying device in the second exemplary embodiment is shorter than in the first exemplary embodiment. This is achieved in that the upper end of the blowing nozzles 29 and 30 ends at a much smaller distance in front of the inlet-side housing wall 39 than in the first exemplary embodiment. However, because then the space between the upper end of the blow nozzles and the inlet-side housing wall 39 is no longer sufficient to provide a sufficiently large exhaust air opening in the upper side 31 of the housing, the exhaust air opening 38 in the second exemplary embodiment is seen in the conveying direction 7 over the upper end of the Blow nozzles 29 and 30 also extended. This was possible without removing the shield between the first, moist region 36 and the second, dry region 37 of the device, by changing the design of the shields: up to a predetermined height H, the shields 33 and 34 are still arranged and performed as in the first embodiment. From this predetermined height H, however, the rubber lips run vertically upward on the housing rear wall 34 and on the front housing wall 35 and are fastened with their longitudinal edge further in the center of the housing to a triangular-shaped intermediate wall 45 in the view according to FIG its inlet-side edge 46 is attached to the outside of the respective nozzle, extends in the conveying direction 7 - preferably parallel to the glass panel running plane 6 - and is connected to the rubber lip on its outlet-side edge 47.

Auf diese Weise ist ab der Höhe H ein Abluftschacht mit gleichbleibendem Querschnitt gebildet, durch welchen die Abluft bei jeder Glastafelgröße bequem nach oben entweichen kann. Da die Blasdüsen 29 und 30 mit ihrem oberen Ende im Bereich dieses Abluftschachtes liegen, werden die Rohre 43 und 44 für die Luftzufuhr zu den Blasdüsen durch die Abluftöffnung 38 hindurch in das Gehäuse hineingeführt.In this way, an exhaust duct with a constant cross-section is formed from height H, through which the exhaust air can easily escape upwards with any size of glass sheet. Since the blowing nozzles 29 and 30 lie with their upper end in the area of this exhaust duct, the pipes 43 and 44 for the air supply to the blowing nozzles are guided through the exhaust air opening 38 into the housing.
