Definitions
- the invention relates to a method and a device for sealing insulating glass blanks.
- the sealing compound When sealing, i.e. when filling the edge joint of insulating glass blanks with sealing compound, the sealing compound is introduced into the edge joint from at least one filling nozzle that is moved along the edge joint of the insulating glass blank.
- EP 0 337 978 A , FR 25 60 813 A , EP 0 252 066 A , GB-A-20 16 960 , DE-OS 28 46 785 , DE 29 07 210 A1 , DE 28 16 437 B1 and EP 0 391 884 A1 is referenced for example.
- DE 29 07 210 A1 is a method of sealing Insulating glass blanks described in which the throttling of the supply of sealing compound always takes place simultaneously with the slowing down of the movement of the insulating glass blank.
- the insulating glass blank is moved linearly with interruptions during the filling of edge joints parallel to the transport direction and the filling nozzle is moved transversely to the conveying direction when the insulating glass blank is stationary when edge joints aligned transversely to the conveying direction are to be filled.
- the filling nozzle can be displaced on a beam which is oriented transversely to the conveying direction and which is attached to the machine frame in a non-adjustable manner in the conveying direction. This also applies to devices with two filling nozzles. Both known automatic sealing machines, the filling nozzle or the filling nozzles are not movable in the conveying direction of the insulating glass blank.
- the one-nozzle sealing machine from Erdmann with the type designation " 7500 Series Vertical IG Secondary Sealer "is arranged in an insulating glass line of the type” Erdmann Vertical Insulating Glass (IF) Line "(cf. www.youtube.com/watch?v GlwRurxOtVo, uploaded 02.10.2010 ).
- the automatic sealing machine has a supporting wall for insulating glass blanks, which is formed by several bars that are fixedly mounted in the machine frame and equipped with freely rotating rollers.
- Linear conveyors in the form of conveyor belts with lateral guide rollers (on the inlet side) and in the form of conveyor rollers (on the outlet side) are provided at the lower edge of the support wall. The linear conveyor on the inlet side is lowered when sealing is carried out.
- suction heads are provided as holding devices for the insulating glass blank to be sealed, which can be adjusted back and forth across the supporting wall.
- the suction heads can be placed on an insulating glass blank to be sealed.
- the insulating glass blank is held exclusively by the suction heads, which are arranged in the supporting wall, so that the edges of the insulating glass blank are free and the sealing nozzle can be moved around the insulating glass blank along the four edges, while in the edge joint of the insulating glass blank sealing compound is filled.
- a support finger is assigned to each suction head.
- the support fingers can independently of one another from a horizontal pivot axes Ready position can be pivoted into an approximately horizontal effective position.
- a support finger is swiveled up from below in contact with the lower edge of the insulating glass blank.
- the support finger is pivoted downwards when the sealing nozzle moves along the lower edge of the insulating glass blank during sealing.
- the problem with the known methods for sealing and with the devices proposed for this purpose is that because of the filling nozzle / filling nozzles which cannot be adjusted or displaced in the conveying direction, moving the insulating glass blank through a sealing station when sealing edge joints that are transverse to the direction of movement of the insulating glass Blanks run, interrupted and must be resumed. This extends the cycle time because the insulating glass blank is slowed down and accelerated. This problem occurs particularly with large and heavy insulating glass blanks.
- US 2015/0354266 A1 shows and describes a method and a device for producing insulating glass, comprising a device for attaching a spacer to a glass pane and a device for filling the edge joint of an insulating glass blank with filler (sealing station).
- a filling nozzle on a bar can be adjusted transversely to the conveying direction of the insulating glass blank in order to seal sections of the edge joint of the insulating glass blank that are oriented transversely to the conveying direction.
- the bar itself can also be adjusted in the conveying direction so that it can be moved further together with an insulating glass blank so that space is created for the removal of another insulating glass blank.
- US 2015/0354266 A1 does not disclose that an insulating glass blank is moved in the conveying direction when sections of the edge joint of the insulating glass blank that are oriented transversely to the conveying direction are sealed will.
- the in US 2015/0354266 A1 The reference to a continuous movement of the insulating glass blank is intended to mean that the insulating glass blank never has to be moved against the direction of conveyance, as shown in US 2015/0354266 A1 , Paragraph [0074] is expressly mentioned.
- the invention is based on the object of designing the sealing of insulating glass blanks in such a way that the disadvantages that occur during sealing due to the braking and acceleration of insulating glass blanks are no longer present.
- the basic idea of the invention is that the at least one filling nozzle is moved during the sealing, in particular at least during individual sections of the sealing, parallel to the direction in which the insulating glass blank is moved during the sealing.
- the filling nozzle can be moved in the same direction as the insulating glass blank to be sealed or in the opposite direction.
- One possible embodiment of the method according to the invention provides for the insulating glass blank to be sealed to be moved continuously during sealing, the at least one filling nozzle with the insulating glass blank being moved when the direction of movement (conveying direction) of the insulating glass blank non-parallel areas of the edge joint of the insulating glass blank are sealed.
- the insulating glass blank is (briefly) stopped during sealing.
- Such a case exists, for example, when long (large) insulating glass blanks are to be sealed in the conveying direction.
- the area in which the filling nozzle can be moved in the conveying direction can be too short, so that the filling nozzle arrives at the end of its movement range before the section of the edge joint of the insulating glass blank that is oriented transversely to the conveying direction and is to be filled with sealing compound filled (sealed).
- the method according to the invention usually allows the insulating glass blank, according to a preferred embodiment of the method, to be moved continuously in the conveying direction, if necessary at different, high speeds.
- the possibility provided according to the invention also allows the filling nozzle to be moved in the conveying direction, so that with small insulating glass blanks only the filling nozzle is moved and the insulating glass blank is not moved or only moves slightly in the conveying direction.
- the speed with which the filling nozzle is moved in order to adapt it to the prevailing circumstances (size of the insulating glass blank, cross-sectional size of the edge joint of the insulating glass blank).
- the speed of the movements of the filling nozzle both in and across the conveying direction does not have to be be constant, but can also be changed within the scope of the invention during a sealing process.
- the possibilities allow not only to change the speed at which the insulating glass blank is moved (in the conveying direction), but also to change the speed at which the filling nozzle is moved, in particular to change it independently of one another, so that cycle times optimized and the (horizontal) dimensions of the sealing station can be reduced without the advantages of the invention being lost.
- Another advantage of the invention consists in adapting the cycle times of the method according to the invention and the device according to the invention to the capacities of upstream and downstream system parts without adversely affecting the quality of the sealing of insulating glass blanks.
- the required relative movement between the filling nozzle and the insulating glass blank can be achieved by moving only the insulating glass blank or by both move the insulating glass blank and the filling nozzle in the conveying direction at different speeds.
- the filling nozzle When filling sections of the edge joint that are parallel to the conveying direction, the filling nozzle is not moved transversely to the conveying direction. When “inclined” or “curved” sections of the edge joint are to be filled with sealing compound, the filling nozzle is moved transversely to the conveying direction in order to follow the "inclined” or “curved” section of the edge joint.
- An advantage of the method of operation proposed according to the invention when sealing insulating glass blanks is that the sluggish regulation of the amount of sealing compound that is dispensed from the filling nozzle into the edge joint per unit of time is achieved by the quick regulation of the speed of the movements of the filling nozzle and / or of the insulating glass blank can be compensated.
- Another advantage of the method according to the invention and the device according to the invention is that the movements of the insulating glass blank required in the prior art without it being sealed ("empty runs") in order to correctly align it for sealing relative to the at least one filling nozzle , are dispensable.
- the insulating glass blank, while it is being sealed is moved continuously in the conveying direction.
- the at least one filling nozzle when the sealing compound is introduced into sections of the edge joint of the insulating glass blank which are aligned parallel to the conveying direction stands still in the conveying direction or at a speed different from the speed V 1 of the movement of the insulating glass blank V 2 is moved.
- the at least one Filling nozzle when introducing sealing compound into sections of the edge joint aligned transversely to the conveying direction at the same speed V 2 as the insulating glass blank is moved in the conveying direction and additionally transversely to the conveying direction.
- the at least one filling nozzle in addition to its movement parallel to the conveying direction, is moved transversely to the conveying direction when introducing filling compound into sections of the edge joint that enclose an angle to the conveying direction.
- a single filling nozzle is used, from which sealing compound is successively introduced into all sections of the edge joint of an insulating glass blank.
- the at least one filling nozzle when the sealing compound is introduced into a section of the edge joint aligned parallel to the conveying direction, is moved in the conveying direction at a speed V 2 , which is dependent on the speed V 1 of the movement of the insulating glass
- the blank is different, in particular higher, in such a way that the filling nozzle moves from one end of the section of the edge joint to the other end of the section of the edge joint in relation to the conveying direction.
- one of the filling nozzles sealing compound exclusively in the section of the edge joint that extends parallel to the conveying direction adjacent to the conveying device is, introduces, and that the second filling nozzle introduces sealing compound into the other sections of the edge joint of the insulating glass blank.
- the first and the second filling nozzle simultaneously introduce sealing compound into sections of the edge joint of the insulating glass blank that are aligned parallel or at an oblique angle to the conveying direction.
- the insulating glass blank is moved in the conveying direction at different speeds V 1 while the sealing compound is being introduced.
- the insulating glass blank is held during delivery and removal and during sealing by suction cups applied to a surface of a first glass pane of the insulating glass blank and subjected to negative pressure, and that the second glass pane of the insulating glass blank is supported by support elements that act on it exclusively from below.
- the support elements engaging the second glass pane of the insulating glass blank are removed from the second glass pane of the insulating glass blank in the region of the at least one filling nozzle.
- the support elements rest on the second glass pane of the insulating glass blank before and after the filling nozzle, which introduces sealing compound into the lower, horizontal section of the edge joint of the insulating glass blank.
- the conveying device for the insulating glass blank is set up to continuously convey the insulating glass blank during the entire sealing process.
- the conveying device comprises a linear conveyor engaging the lower edge of the insulating glass blank and a roller bar provided in the region of the upper edge of the insulating glass blank.
- the linear conveyor comprises suction cups and support elements which can be moved jointly and synchronously in the conveying direction of the insulating glass blank.
- the suction cups engage laterally on the surface of one glass pane of the insulating glass blank facing the machine frame of the device, and that the support elements on the glass pane of the insulating glass blank facing away from the machine frame of the device attack down below.
- support elements can be removed from the lower edge of the glass pane of the insulating glass blank in the area of the filling nozzle.

Es ist bekannt und beim Herstellen von Isolierglas üblich, die in einem Isolierglas-Rohling zwischen den Glasscheiben und außerhalb des Abstandhalters liegende, nach außen hin offene Randfuge von Isolierglas-Rohlingen, bestehend aus wenigstens zwei Glasscheiben mit dazwischen gefügtem Abstandhalter, der mit den Glasscheiben verbunden ist, mit Versiegelungsmasse zu füllen, um den endgültigen Verbund der Glasscheiben von Isolierglas zu erzielen.It is known and customary in the manufacture of insulating glass that the outwardly open edge joint of insulating glass blanks, consisting of at least two glass panes with a spacer inserted in between, which is connected to the glass panes, is in an insulating glass blank between the glass panes and outside the spacer is to be filled with sealing compound in order to achieve the final bond between the panes of insulating glass.
Beim Versiegeln, also beim Füllen der Randfuge von Isolierglas-Rohlingen mit Versiegelungsmasse, wird die Versiegelungsmasse aus wenigstens einer Fülldüse, die entlang der Randfuge des Isolierglas-Rohlings bewegt wird, in die Randfuge eingebracht.When sealing, i.e. when filling the edge joint of insulating glass blanks with sealing compound, the sealing compound is introduced into the edge joint from at least one filling nozzle that is moved along the edge joint of the insulating glass blank.

Insbesondere ist es bei den bekannten Verfahren zum Versiegeln von Isolierglas-Rohlingen problematisch, die Isolierglas-Rohlinge während und nach dem Versiegeln zu transportieren, da Versiegelungsmasse, so lange sie noch nicht ausgehärtet ist, sehr klebrig ist und Transportmittel verschmutzt, die am (unteren) Rand des Isolierglas-Rohlings angreifen. Um dieses Problem zu lösen, sind verschiedene Vorschläge für Fördermittel gemacht worden. Auf
Sowohl beim Versiegeln von Isolierglas-Rohlingen mit einer Fülldüse ("Ein-Düsen-Versiegelungsautomat") als auch beim Versiegeln von Isolierglas-Rohlingen mit mehr als einer Fülldüse, insbesondere mit zwei, Fülldüsen ("Zwei-Düsen-Versiegelungsautomat"), werden die Bewegungen zwischen der wenigstens einen Fülldüse und dem Isolierglas-Rohling, um die Fülldüse entlang der Randfuge zu bewegen, durch Bewegen des Isolierglas-Rohlings in horizontaler Richtung (parallel zur Förderrichtung des Isolierglas-Rohlings) und Bewegen der Fülldüse in vertikaler Richtung (quer zur Förderrichtung des Isolierglas-Rohlings) erreicht. Es wird also der Isolierglas-Rohling während des Füllens von zur Transportrichtung parallelen Randfugen mit Unterbrechungen linear bewegt und die Fülldüse bei stillstehendem Isolierglas-Rohling quer zur Förderrichtung bewegt, wenn quer zur Förderrichtung ausgerichtete Randfugen zu füllen sind.Both when sealing insulating glass blanks with one filling nozzle ("one-nozzle automatic sealing machine") and when sealing insulating glass blanks with more than one filling nozzle, in particular with two filling nozzles ("two-nozzle automatic sealing machine"), the Movements between the at least one filling nozzle and the insulating glass blank to move the filling nozzle along the edge joint by moving the insulating glass blank in the horizontal direction (parallel to the conveying direction of the insulating glass blank) and moving the filling nozzle in the vertical direction (transversely to the conveying direction of the insulating glass blank). The insulating glass blank is moved linearly with interruptions during the filling of edge joints parallel to the transport direction and the filling nozzle is moved transversely to the conveying direction when the insulating glass blank is stationary when edge joints aligned transversely to the conveying direction are to be filled.
Bei bekannten Vorrichtungen ist die Fülldüse an einem quer zur Förderrichtung ausgerichteten Balken, der am Maschinengestell in Förderrichtung nicht verstellbar befestigt ist, verschiebbar. Dies gilt auch für Vorrichtungen mit zwei Fülldüsen. Bei den bekannten Versiegelungsautomaten ist die Fülldüse oder die Fülldüsen in Förderrichtung des Isolierglas-Rohlings nicht beweglich.In known devices, the filling nozzle can be displaced on a beam which is oriented transversely to the conveying direction and which is attached to the machine frame in a non-adjustable manner in the conveying direction. This also applies to devices with two filling nozzles. Both known automatic sealing machines, the filling nozzle or the filling nozzles are not movable in the conveying direction of the insulating glass blank.
Bekannt ist auch ein Verfahren zum Versiegeln von Isolierglas-Rohlingen ("Erdmann-Verfahren") mit Hilfe eines Eindüsen-Versiegelungsautomaten.Also known is a method for sealing insulating glass blanks ("Erdmann method") with the aid of an automatic single-nozzle sealing machine.
Der Eindüsen-Versiegelungsautomat von Erdmann mit der Typenbezeichnung "
Problematisch bei den bekannten Verfahren zum Versiegeln und bei den hierzu vorgeschlagenen Vorrichtungen ist es, dass wegen der in Förderrichtung nicht verstell- oder verschiebbaren Fülldüse/Fülldüsen das Bewegen des Isolierglas-Rohlings durch eine Versiegelungsstation beim Versiegeln von Randfugen, die quer zur Bewegungsrichtung des Isolierglas-Rohlings verlaufen, unterbrochen und wieder aufgenommen werden muss. Das verlängert wegen des Abbremsens und Beschleunigens des Isolierglas-Rohlings die Taktzeit. Dieses Problem tritt besonders bei großen und schweren Isolierglas-Rohlingen auf.The problem with the known methods for sealing and with the devices proposed for this purpose is that because of the filling nozzle / filling nozzles which cannot be adjusted or displaced in the conveying direction, moving the insulating glass blank through a sealing station when sealing edge joints that are transverse to the direction of movement of the insulating glass Blanks run, interrupted and must be resumed. This extends the cycle time because the insulating glass blank is slowed down and accelerated. This problem occurs particularly with large and heavy insulating glass blanks.
Der Erfindung liegt die Aufgabe zugrunde, das Versiegeln von Isolierglas-Rohlingen so zu gestalten, dass die beim Versiegeln durch das Abbremsen und Beschleunigen von Isolierglas-Rohlingen auftretenden Nachteile nicht mehr gegeben sind.The invention is based on the object of designing the sealing of insulating glass blanks in such a way that the disadvantages that occur during sealing due to the braking and acceleration of insulating glass blanks are no longer present.
Gelöst wird diese Aufgabe erfindungsgemäß mit einem Verfahren mit den Merkmalen von Anspruch 1 einerseits und mit einer Vorrichtung, welche die Merkmale des unabhängigen, auf die Vorrichtung gerichteten Anspruches aufweist, anderseits.This object is achieved according to the invention with a method with the features of
Bevorzugte und vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.Preferred and advantageous embodiments of the invention are the subject of the subclaims.
Grundgedanke der Erfindung ist es, dass die wenigstens eine Fülldüse während des Versiegelns, insbesondere wenigstens während einzelner Abschnitte des Versiegelns, parallel zu der Richtung bewegt wird, in welcher der Isolierglas-Rohling während des Versiegelns bewegt wird. Die Fülldüse kann während des Versiegelns in derselben Richtung wie der zu versiegelnde Isolierglas-Rohling oder in die entgegengesetzte Richtung bewegt werden.The basic idea of the invention is that the at least one filling nozzle is moved during the sealing, in particular at least during individual sections of the sealing, parallel to the direction in which the insulating glass blank is moved during the sealing. During sealing, the filling nozzle can be moved in the same direction as the insulating glass blank to be sealed or in the opposite direction.
In einer möglichen Ausführungsform des erfindungsgemäßen Verfahrens ist vorgesehen, den Isolierglas-Rohling, der zu versiegeln ist, während des Versiegelns kontinuierlich zu bewegen, wobei die wenigstens eine Fülldüse mit dem Isolierglas-Rohling bewegt wird, wenn zur Bewegungsrichtung (Förderrichtung) des Isolierglas-Rohlings nicht parallele Bereiche der Randfuge des Isolierglas-Rohlings versiegelt werden.One possible embodiment of the method according to the invention provides for the insulating glass blank to be sealed to be moved continuously during sealing, the at least one filling nozzle with the insulating glass blank being moved when the direction of movement (conveying direction) of the insulating glass blank non-parallel areas of the edge joint of the insulating glass blank are sealed.
Bei der Erfindung sind die mit dem Verzögern (Abbremsen) und Beschleunigen des zu versiegelnden Isolierglas-Rohlings verbundenen Probleme nicht mehr gegeben.With the invention, the problems associated with decelerating (braking) and accelerating the insulating glass blank to be sealed are no longer present.
In bestimmten Fällen kann es vorkommen, dass der Isolierglas-Rohling während des Versiegelns (kurz) angehalten wird. Ein solcher Fall ist beispielsweise gegeben, wenn in Förderrichtung lange (große) Isolierglas-Rohlinge zu versiegeln sind. In solchen Fällen kann der Bereich, in dem die Fülldüse in Förderrichtung bewegt werden kann, zu kurz sein, so dass die Fülldüse am Ende ihres Bewegungsbereiches ankommt, bevor noch der quer zur Förderrichtung ausgerichtete, mit Versiegelungsmasse zu füllende Abschnitt der Randfuge des Isolierglas-Rohlings gefüllt (versiegelt) ist. Dies tritt aber nur in Ausnahmefällen ein.In certain cases it can happen that the insulating glass blank is (briefly) stopped during sealing. Such a case exists, for example, when long (large) insulating glass blanks are to be sealed in the conveying direction. In such cases, the area in which the filling nozzle can be moved in the conveying direction can be too short, so that the filling nozzle arrives at the end of its movement range before the section of the edge joint of the insulating glass blank that is oriented transversely to the conveying direction and is to be filled with sealing compound filled (sealed). However, this only occurs in exceptional cases.
Für gewöhnlich erlaubt es das erfindungsgemäße Verfahren, dass der Isolierglas-Rohling gemäß einer bevorzugten Ausführungsform des Verfahrens in Förderrichtung kontinuierlich gegebenenfalls mit unterschiedlichen, hohen Geschwindigkeiten bewegt wird.The method according to the invention usually allows the insulating glass blank, according to a preferred embodiment of the method, to be moved continuously in the conveying direction, if necessary at different, high speeds.
Ebenso erlaubt es die erfindungsgemäß vorgesehene Möglichkeit, die Fülldüse auch in Förderrichtung zu bewegen, so dass bei kleinen Isolierglas-Rohlingen so gearbeitet wird, dass nur die Fülldüse bewegt wird und der Isolierglas-Rohling nicht bewegt wird oder eine nur geringfügige Bewegung in Förderrichtung ausführt.The possibility provided according to the invention also allows the filling nozzle to be moved in the conveying direction, so that with small insulating glass blanks only the filling nozzle is moved and the insulating glass blank is not moved or only moves slightly in the conveying direction.
Im Rahmen der Erfindung ist auch in Betracht gezogen, die Geschwindigkeit, mit der die Fülldüse bewegt wird, zu ändern, um sie den jeweils herrschenden Umständen (Größe des Isolierglas-Rohlings, Querschnittsgröße der Randfuge des Isolierglas-Rohlings) anzupassen. Die Geschwindigkeit der Bewegungen der Fülldüse sowohl in als auch quer zur Förderrichtung muss nicht konstant sein, sondern kann im Rahmen der Erfindung auch während eines Versiegelungsvorganges geändert werden.In the context of the invention, it is also considered to change the speed with which the filling nozzle is moved in order to adapt it to the prevailing circumstances (size of the insulating glass blank, cross-sectional size of the edge joint of the insulating glass blank). The speed of the movements of the filling nozzle both in and across the conveying direction does not have to be be constant, but can also be changed within the scope of the invention during a sealing process.
Bei der Erfindung erlauben es die Möglichkeiten, nicht nur die Geschwindigkeit, mit welcher der Isolierglas-Rohling (in Förderrichtung) bewegt wird, sondern auch die Geschwindigkeit, mit der die Fülldüse bewegt wird, zu ändern, insbesondere voneinander unabhängig zu ändern, so dass Taktzeiten optimiert und die (horizontalen) Abmessungen der Versiegelungsstation verkleinert werden, ohne dass die Vorteile der Erfindung verloren gehen.In the invention, the possibilities allow not only to change the speed at which the insulating glass blank is moved (in the conveying direction), but also to change the speed at which the filling nozzle is moved, in particular to change it independently of one another, so that cycle times optimized and the (horizontal) dimensions of the sealing station can be reduced without the advantages of the invention being lost.
Ein weiterer Vorteil der Erfindung besteht darin, die Taktzeiten des erfindungsgemäßen Verfahrens und der erfindungsgemäßen Vorrichtung ohne nachteiligen Einfluss auf die Qualität der Versiegelung von Isolierglas-Rohlingen an die Kapazitäten von vorgeschalteten und nachgeschalteten Anlageteilen anzupassen. Dies bewirkt, dass in der Versiegelungsstation vorgeschalteten Anlageteilen (z.B. Gasfüllpressen) kein Stau entsteht, weil das Versiegeln zu lange dauert einerseits und dass nachgeschaltete Anlagenteile (z.B. Abstapeleinrichtungen) nicht auf versiegelte Isolierglas-Rohlinge, also fertiges Isolierglas, warten müssen, anderseits.Another advantage of the invention consists in adapting the cycle times of the method according to the invention and the device according to the invention to the capacities of upstream and downstream system parts without adversely affecting the quality of the sealing of insulating glass blanks. This means that there is no jam in the upstream system components (e.g. gas filling presses) because the sealing takes too long on the one hand and that downstream system components (e.g. stacking devices) do not have to wait for sealed insulating glass blanks, i.e. finished insulating glass, on the other.
Beim Versiegeln von parallel oder unter einem vom rechten Winkel abweichenden Winkel zur Förderrichtung verlaufenden ("schrägen") Abschnitten der Randfuge kann die erforderliche Relativbewegung zwischen der Fülldüse und dem Isolierglas-Rohling erreicht werden, indem sich nur der Isolierglas-Rohling bewegt oder indem sich sowohl der Isolierglas-Rohling als auch die Fülldüse in Förderrichtung mit voneinander abweichenden Geschwindigkeiten bewegen.When sealing parallel or at an angle deviating from the right angle to the conveying direction ("inclined") sections of the edge joint, the required relative movement between the filling nozzle and the insulating glass blank can be achieved by moving only the insulating glass blank or by both move the insulating glass blank and the filling nozzle in the conveying direction at different speeds.
Beim Füllen von zur Förderrichtung parallelen Abschnitten der Randfuge wird die Fülldüse nicht quer zur Förderrichtung bewegt. Wenn "schräge" oder "gekrümmte" Abschnitte der Randfuge mit Versiegelungsmasse zu füllen sind, wird die Fülldüse quer zur Förderrichtung bewegt, um dem "schrägen" oder "gekrümmten" Abschnitt der Randfuge zu folgen.When filling sections of the edge joint that are parallel to the conveying direction, the filling nozzle is not moved transversely to the conveying direction. When "inclined" or "curved" sections of the edge joint are to be filled with sealing compound, the filling nozzle is moved transversely to the conveying direction in order to follow the "inclined" or "curved" section of the edge joint.
Ein Vorteil der erfindungsgemäß vorgeschlagenen Arbeitsweise beim Versiegeln von Isolierglas-Rohlingen liegt auch darin, dass die träge Regelung der Menge an Versiegelungsmasse, die je Zeiteinheit aus der Fülldüse in die Randfuge abgegeben wird, durch die flinke Regelung der Geschwindigkeit der Bewegungen der Fülldüse und/oder des Isolierglas-Rohlings kompensiert werden kann.An advantage of the method of operation proposed according to the invention when sealing insulating glass blanks is that the sluggish regulation of the amount of sealing compound that is dispensed from the filling nozzle into the edge joint per unit of time is achieved by the quick regulation of the speed of the movements of the filling nozzle and / or of the insulating glass blank can be compensated.
Ein weiterer Vorteil des erfindungsgemäßen Verfahrens und der erfindungsgemäßen Vorrichtung liegt darin, dass die im Stand der Technik erforderlichen Bewegungen des Isolierglas-Rohlings, ohne dass dieser versiegelt wird ("Leerfahrten"), um diesen für das Versiegeln relativ zu der wenigstens einen Fülldüse richtig auszurichten, entbehrlich sind.Another advantage of the method according to the invention and the device according to the invention is that the movements of the insulating glass blank required in the prior art without it being sealed ("empty runs") in order to correctly align it for sealing relative to the at least one filling nozzle , are dispensable.
In einer Ausführungsform des Verfahrens der Erfindung kann vorgesehen sein, dass der Isolierglas-Rohling, während er versiegelt wird, kontinuierlich in die Förderrichtung bewegt wird. Bei der Erfindung ist vorgesehen, dass die wenigstens eine Fülldüse beim Einbringen von Versiegelungsmasse in Abschnitte der Randfuge des Isolierglas-Rohlings, die parallel zur Förderrichtung ausgerichtet sind, in Förderrichtung stillsteht oder mit einer von der Geschwindigkeit V1 der Bewegung des Isolierglas-Rohlings verschiedenen Geschwindigkeit V2 bewegt wird.In one embodiment of the method of the invention it can be provided that the insulating glass blank, while it is being sealed, is moved continuously in the conveying direction. In the invention it is provided that the at least one filling nozzle when the sealing compound is introduced into sections of the edge joint of the insulating glass blank which are aligned parallel to the conveying direction, stands still in the conveying direction or at a speed different from the speed V 1 of the movement of the insulating glass blank V 2 is moved.

In der nachstehenden Beschreibung wird das Versiegeln von Isolierglas-Rohlingen, die während des Versiegelns, wie derzeit allgemein üblich, im Wesentlichen lotrecht ausgerichtet durch eine Versiegelungsvorrichtung (Versiegelungsstation) bewegt (transportiert) werden, beschrieben. Dessen ungeachtet ist das erfindungsgemäße Verfahren nicht auf das Versiegeln von beim Versiegeln lotrecht ausgerichteten Isolierglas-Rohlingen beschränkt. Vielmehr können mit dem erfindungsgemäßen Verfahren auch liegend durch eine Versiegelungsvorrichtung bewegte Isolierglas-Rohlinge versiegelt werden.The following description describes the sealing of insulating glass blanks which, as is generally customary at the present time, are moved (transported) essentially vertically by a sealing device (sealing station) during sealing. Regardless of this, the method according to the invention is not limited to the sealing of insulating glass blanks which are vertically aligned during sealing. Rather, insulating glass blanks moved horizontally by a sealing device can also be sealed with the method according to the invention.
Bei dem erfindungsgemäßen Verfahren kann beispielsweise wie folgt gearbeitet werden:
Zunächst wird der untere, horizontale, zur Förderrichtung parallele Abschnitt 13 der Randfuge des Isolierglas-Rohlings 1 gefüllt, wobei der Isolierglas-Rohling 1 kontinuierlich bewegt wird. Die Fülldüse 7 kann parallel zur Förderrichtung (Pfeil 17) des Isolierglas-Rohlings 1 mit einer von der Geschwindigkeit des Isolierglas-Rohlings 1 abweichenden Geschwindigkeit bewegt werden. Die Fülldüse 7 muss dabei aber nicht bewegt werden.The process according to the invention can be carried out, for example, as follows:
First, the lower,
Dann wird der bezogen auf die Förderrichtung hintere, quer zur Förderrichtung ausgerichtete (lotrechte) Abschnitt 9 der Randfuge des Isolierglas-Rohlings 1 gefüllt, wobei sich der Balken 5 mit der Fülldüse 7 (Versiegelungsdüse) synchron mit dem Isolierglas-Rohling 1 bewegt und die Fülldüse 7 zum Füllen des hinteren Abschnittes 9 der Randfuge entlang des Balkens 5 nach unten oder nach oben bewegt wird.Then the
Beim Füllen des oberen, horizontalen Abschnittes 11 der Randfuge des Isolierglas-Rohlings 1 wird der Isolierglas-Rohling 1 weiterhin kontinuierlich bewegt, um so eine Relativbewegung zwischen Fülldüse 7 und Isolierglas-Rohling 1 zu erreichen. Die Fülldüse 7 kann parallel zur Förderrichtung (Pfeil 17) des Isolierglas-Rohlings 1 mit einer von der Geschwindigkeit des Isolierglas-Rohlings 1 abweichenden Geschwindigkeit bewegt werden, muss aber nicht bewegt werden.When filling the upper,
Zum Füllen des vorderen, quer zur Förderrichtung ausgerichteten, (lotrechten) Abschnittes 3 der Randfuge wird so gearbeitet, wie dies im Zusammenhang mit dem Füllen des hinteren Abschnittes 9 der Randfuge des Isolierglas-Rohlings 1 beschrieben ist.To fill the front (vertical)
Beim Füllen von Abschnitten der Randfuge, die zur Förderrichtung (Pfeil 17) des Isolierglas-Rohlings 1 parallel ausgerichtet sind, kann die Fülldüse 7 am Versiegelungskopf 19 und die in
Das Bewegen des Versiegelungskopfes 19 mit der Fülldüse 7 (und auch des gegebenenfalls vorgesehenen zweiten Versiegelungskopfes 21 mit der Fülldüse 7) in Förderrichtung (Pfeil 17) erfolgt durch Bewegen des Balkens 5.Moving the sealing
Beispielsweise kann, wenn die Versiegelungsstation 15 (nur) eine Fülldüse 7 aufweist (
Der Isolierglas-Rohling 1 wird von einer Fördereinrichtung 25 mit einer Geschwindigkeit V1 in Richtung des Pfeiles 17 durch die Versiegelungsstation 15 bewegt. Die Fülldüse 7 füllt bei beispielsweise stillstehendem Balken 5 (V2 = 0) oder mit einer von der Geschwindigkeit V1 abweichenden Geschwindigkeit V2 bewegtem Balken 5 und bei in Richtung der Längserstreckung des Balkens 5 stillstehendem Versiegelungskopf 19 mit der Fülldüse 7 den unteren, horizontalen Abschnitt 13 der Randfuge des Isolierglas-Rohlings 1.The insulating

In dem Maschinengestell 23 ist eine Fördereinrichtung 25 für zu versiegelnde Isolierglas-Rohlinge 1 vorgesehen. Die Fördereinrichtung 25 umfasst Sauger 27 und den Saugern 27 zugeordnete Abstützelemente 29. Dabei ist vorgesehen, dass die Sauger 27 an der hinteren, dem Maschinengestell 23 zugekehrten Fläche der einen Glasscheibe 33 eines Isolierglas-Rohlings 1 angreifen und die Abstützelemente 29 am unteren Rand (nur) der vorderen, vom Maschinengestell 23 abgekehrten Glasscheibe 31 des Isolierglas-Rohlings 1 angreifen. So ist ein Verschieben (Absinken) der vorderen Glasscheibe 31 relativ zur hinteren, von den Saugern 27 gehaltenen Glasscheibe 33 des Isolierglas-Rohlings 1 vermieden. Des Weiteren wird so vermieden, dass Teile der Fördereinrichtung 25 mit der in die Randfuge eines Isolierglas-Rohlings 1 eingebrachten Versiegelungsmasse in Berührung kommen und verschmutzen. Im Übrigen ist die Vorrichtung 15 auch für das Versiegeln von Isolierglas-Rohlingen 1 für Stufenelemente (die Glasscheiben des Isolierglas-Rohlings 1 sind nicht gleich groß) geeignet.A conveying
Der obere Rand des Isolierglas-Rohlings 1 wird durch einen Rollenbalken 35 abgestützt, der an der hinteren Fläche der Glasscheibe 33 angreift und im Maschinengestell 23 der Höhe nach verstellbar angeordnet ist, damit er quer zur Förderrichtung (Pfeil 17) so verstellt werden kann, dass er am Isolierglas-Rohling 1 (nur) im Bereich des oberen Randes angreift.The upper edge of the insulating

Dadurch, dass der Balken 5, an dem der Versiegelungskopf 19 mit seiner Fülldüse 7 auf und ab verschiebbar (Pfeil 42) geführt ist, in Förderrichtung (horizontal, Doppelpfeil 41) verschiebbar ist, kann er während des Versiegelns von Abschnitten der Randfuge des Isolierglas-Rohlings 1 mit diesem mitbewegt werden.Because the
Dies erlaubt die erfindungsgemäße Arbeitsweise, bei welcher der Isolierglas-Rohling 1 während des Versiegelns in der Versiegelungsstation 15 nicht stehen bleibt, sondern ständig bewegt wird. Die Relativbewegungen zwischen dem Versiegelungskopf 19 mit Fülldüse 7 und der Randfuge des Isolierglas-Rohlings 1 werden durch Bewegen des Isolierglas-Rohlings 1 mit Hilfe der Fördereinrichtung 25 und abschnittsweises (zeitweises) Bewegen der Fülldüse 7 sowohl quer zur Förderrichtung (Doppelpfeil 42) als auch in horizontaler Richtung (Doppelpfeil 41) in oder gegen die Förderrichtung (Pfeil 17 von

Zusammenfassend kann ein Ausführungsbeispiel der Erfindung wie folgt beschrieben werden:
Beim Versiegeln von Isolierglas-Rohlingen 1 wird der Isolierglas-Rohling 1 im Wesentlichen kontinuierlich durch eine Versiegelungsstation 15 bewegt. Wenn zur Förderrichtung (Pfeil 17) quer oder schräg ausgerichtete Abschnitte 3, 9 der Randfuge des Isolierglas-Rohlings 1 mit aus einer Fülldüse 7 austretender Versiegelungsmasse gefüllt werden, wird die Fülldüse 7 ebenfalls in Förderrichtung (Pfeil 17) bewegt. Wenn Versiegelungsmasse aus der Fülldüse 7 in zur Förderrichtung (Pfeil 17) parallele Abschnitte 11, 13 des Isolierglas-Rohlings 1 eingebracht wird, wird die Fülldüse 7 in Förderrichtung (Pfeil 17) nicht oder mit einer von der Geschwindigkeit, mit welcher der Isolierglas-Rohling 1 bewegt wird, abweichenden Geschwindigkeit bewegt.In summary, an embodiment of the invention can be described as follows:
