Abstract

The device coats the frame on both sides with sealing and adhesive material. Two nozzles (6, 7) facing each other are mounted close above a horizontal conveyor (1), and are supplied via a metering device. Each nozzle has its own gear pump (12, 13), the two being driven in synchronism and drawing from a common tank (19). The latter can be connected to an adjustable pressure-generator (23, 24), and between each pump and respective nozzle mouth there can be merely a short passage (20, 21) containing no valves. The pumps can have a reversible drive mechanism (18), this being electronically synchronised with the drive to the conveyor.

Description

Die Erfindung geht aus von einer Vorrichtung mit den im Oberbegriff des Anspruchs 1 angegebenen Merkmalen. Eine solche Vorrichtung ist aus der EP-0 333 693 B1 bekannt. Zum Beschichten des Abstandhalterrahmens wird dieser auf den Waagerechtförderer gestellt und mit dessen Hilfe zwischen den beiden einander zugewandten Düsen hindurchgeführt und dabei beidseitig beschichtet.The invention relates to a device with the features specified in the preamble of claim 1. Such a device is known from EP-0 333 693 B1. To coat the spacer frame, it is placed on the horizontal conveyor and, with its help, is passed between the two facing nozzles and coated on both sides.

Für eine qualitativ hochwertige, dauerhaft dichte Verklebung der Glastafeln einer Isolierglasscheibe ist es wichtig, dass man auf beiden Seiten des Abstandhalterrahmens gleich dicke Raupen aus der Kleb- und Dichtmasse erhält. Das ist bei der bekannten Vorrichtung nicht gewährleistet: Bei bekannten Vorrichtungen befindet sich in jedem Düsenkopf ein Drehschieber-Ventil. Beide Düsenköpfe sind mit einem unter Druck stehenden Speicher verbunden, in welchem sich die Kleb- und Dichtmasse befindet. Der Druck im Speicher wird durch einen Tauchkolben erzeugt. Die vom Speicher wegführende Leitung verzweigt sich zu den beiden Düsen, so dass der Druck des Tauchkolbens auch auf die beiden Drehschieber-Ventile übertragen wird. Zum Beschichten der Abstandhalterrahmen werden die Drehschieber-Ventile mittels Parallelgestänge gleichzeitig geöffnet. Danach folgt der Austrag der Kleb- und Dichtmasse dem Weg des geringsten Widerstandes. Mit größerem Abstand einer Düse vom Abstandhalterrahmen wird auch die Dicke der Raupe aus der Kleb- und Dichtmasse dicker. Zum Ausgleich von Dickentoleranzen des Abstandhalterrahmenprofils, insbesondere im Bereich von gebogenen Ecken, können nicht beide Düsen gleichzeitig am Abstandhalterrahmen anliegen, sondern halten einen Abstand ein, der variieren kann. Daher variiert auch die Dicke der Raupe aus der Kleb- und Dichtmasse. Hinzu kommt, dass inbesondere in der Phase des Öffnens und des Schließens der Drehschieber der druckabhängige Austrag der Kleb- und Dichtmasse zufälligen Schwankungen unterliegt, wobei auch die Verschlußzeiten der druckmittelbetätigten Drehschieber nicht exakt synchron sind. Der druckabhängige Austrag der Kleb- und Dichtmasse hat noch den weiteren Nachteil, dass er empfindlich auf Änderungen der Viskosität der Kleb- und Dichtmasse reagiert. Die Viskosität hängt wiederum empfindlich von der Temperatur ab. Umgebungstemperaturschwankungen, hervorgerufen z.B. durch Zugluft infolge Öffnens eines Fabriktores, können schon einen nachteiligen Einfluß auf die Dosiergenauigkeit und damit auf die Gleichmässigkeit (besser gesagt: Ungleichmässigheit) der Raupen aus der Kleb- und Dichtmasse haben.For a high-quality, permanently sealed gluing of the glass panels of an insulating glass pane, it is important that you place the spacer frame on both sides receives equally thick beads from the adhesive and sealant. This is not guaranteed in the known device: in known devices there is a rotary slide valve in each nozzle head. Both nozzle heads are connected to a pressurized reservoir in which the adhesive and sealing compound is located. The pressure in the accumulator is generated by a plunger. The line leading away from the accumulator branches to the two nozzles, so that the pressure of the plunger is also transmitted to the two rotary slide valves. To coat the spacer frames, the rotary slide valves are opened simultaneously using parallel rods. The adhesive and sealant is then discharged in the direction of least resistance. The greater the distance between a nozzle and the spacer frame, the thicker the bead of adhesive and sealing compound becomes. To compensate for thickness tolerances of the spacer frame profile, in particular in the area of curved corners, both nozzles cannot lie against the spacer frame at the same time, but maintain a distance that can vary. Therefore, the thickness of the bead from the adhesive and sealing compound also varies. In addition, in particular in the phase of opening and closing the rotary valve, the pressure-dependent discharge of the adhesive and sealing compound is subject to random fluctuations, the shutter speeds of the pressure-operated rotary valve also not being exactly synchronous. The pressure-dependent discharge of the adhesive and Sealing compound has the further disadvantage that it is sensitive to changes in the viscosity of the adhesive and sealing compound. The viscosity in turn depends on the temperature. Fluctuations in ambient temperature, caused, for example, by drafts due to the opening of a factory gate, can already have a detrimental effect on the dosing accuracy and thus on the uniformity (more precisely: unevenness) of the beads from the adhesive and sealant.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, auf möglichst einfache Weise eine auf beiden Seiten des Abstandhalterrahmens gleiche Raupe aus Kleb- und Dichtmasse zu erzeugen.The present invention has for its object to produce the same bead on both sides of the spacer frame from adhesive and sealant in the simplest possible way.

Diese Aufgabe wird gelöst durch eine Vorrichtung mit den im Anspruch 1 angegebenen Merkmalen. Vorteilhafte Weiterbildungen der Erfindung sind Gegenstand der abhängigen Ansprüche.This object is achieved by a device with the features specified in claim 1. Advantageous developments of the invention are the subject of the dependent claims.

Erfindungsgemäss sind die beim Stand der Technik in den Düsenköpfen vorhandenen Drehschieberventile ersetzt durch synchron angetriebene Zahnradpumpen, welche ihre Kleb- und Dichtmasse aus einem gemeinsamen Speicher beziehen. Das hat zahlreiche Vorteile:

  • Die Zahnradpumpen dosieren die Kleb- und Dichtmasse in erster Linie nicht druckabhängig, sondern mengenmässig (volumenmässig). Einflüsse von Temperaturschwankungen und Viskositätsschwankungen auf die Dosiergenauigkeit sind deshalb vernachlässigbar, insbesondere dann, wenn wie in bevorzugter Weiterbildung der Erfindung die Zahnradpumpen nahe bei den Mündungen der Düsen im jeweiligen Düsenblock vorgesehen sind.
  • Durch den synchronen Antrieb, insbesondere mittels eines gemeinsamen Antriebsaggregates, ist ein absoluter Gleichlauf der Zahnradpumpen gewährleistet, so dass diese denselben Durchsatz an Kleb- und Dichtmasse haben.
  • Die in der Zeiteinheit abgegebene Menge an Kleb- und Dichtmasse kann einfach durch Steuern oder Regeln der Drehzahl eingestellt werden.
  • Deshalb ist auch eine Steuerung des Durchsatzes proportional zur Geschwindigkeit des Waagerechtförderers sehr einfach möglich, und zwar genauer als bei druckabhängigem Dosieren, selbst wenn dort sogenannte Proportionalventile eingesetzt werden.
  • Ventile sind in den Leitungen vom Speicher, aus welchem die Zahnradpumpen die Kleb- und Dichtmasse beziehen, zu den Düsen entbehrlich.
  • Auch ohne Ventile im Düsenkopf kann ein Nachfließen der Kleb- und Dichtmasse zuverlässig verhindert werden, wenn der Beschichtungsvorgang gestoppt wird. Die Verschlußfunktion übernehmen die Zahnradpumpen selbst, welche bei Stillstand den Fluß der Kleb- und Dichtmasse sofort unterbrechen, wobei ein Nachfließen infolge des Entspannens der Kleb- und Dichtmasse, soweit dies überhaupt ein Problem sein sollte, einfach durch einen kurzzeitigen Rückwärtslauf der Zahnradpumpen sicher unterbunden werden kann. Das optimale Ausmaß des Rückwärtslaufes kann nach Erfahrungswerten so eingestellt werden, dass danach die Kleb- und Dichtmasse an der Mündung der Düsen ansteht und beim Start des Beschichtungsvorganges keine Verzögerung eintritt.
  • Durch die Möglichkeit der Proportionalsteuerung abhängig von der Geschwindigkeit des Waagerechtförderers können Abstandhalterrahmen auch im Bereich unterschiedlich gebogener Ecken ausserordentlich gleichmässig beschichtet werden.
  • Dadurch, dass Ventile mit ihren variablen Totzeiten nicht erforderlich sind, können Anfang und Ende des Beschichtungsvorganges genauer festgelegt werden.
  • Die synchron miteinander und mit dem Antrieb des Waagerechtförderers angetriebenen Zahnradpumpen können zu Beginn und zum Ende des Beschichtungsvorganges jeweils eine Rampe fahren, wodurch man die gewünschten Start- und Stopp-Punkte besonders exakt erhält, was selbst in der Startphase und in der Endphase der Beschichtung eine hohe Gleichmässigkeit der Raupe aus der Kleb- und Dichtmasse gewährleistet.
According to the invention, the rotary slide valves present in the nozzle heads in the prior art are replaced by synchronously driven gear pumps, which obtain their adhesive and sealing compound from a common memory. This has numerous advantages:
  • The gear pumps do not dose the adhesive and sealant primarily depending on the pressure, but in terms of volume (volume). Influences of temperature fluctuations and viscosity fluctuations on the metering accuracy are therefore negligible, especially if, as in a preferred development of the invention, the gear pumps are provided close to the mouths of the nozzles in the respective nozzle block.
  • The synchronous drive, in particular by means of a common drive unit, guarantees absolute synchronization of the gear pumps, so that they have the same throughput of adhesive and sealing compound.
  • The amount of adhesive and sealant dispensed in the unit of time can be adjusted simply by controlling or regulating the speed.
  • It is therefore very easy to control the throughput proportional to the speed of the horizontal conveyor, more precisely than with pressure-dependent dosing, even if so-called proportional valves are used there.
  • Valves in the lines from the accumulator, from which the gear pumps obtain the adhesive and sealing compound, to the nozzles can be dispensed with.
  • Even without valves in the nozzle head, the adhesive and sealing compound can be prevented from flowing in reliably if the coating process is stopped. The locking function is carried out by the gear pumps themselves, which immediately stop the flow of the adhesive and sealant when the pump is at a standstill, with subsequent flow due to the relaxation of the adhesive and sealant, if this should be a problem at all, simply prevented by briefly reverse running the gear pumps can. Based on experience, the optimal extent of the reverse run can be set so that the adhesive and sealant is present at the mouth of the nozzles and there is no delay when the coating process starts.
  • Due to the possibility of proportional control depending on the speed of the horizontal conveyor, spacer frames can also be coated extremely evenly in the area of differently curved corners.
  • Because valves with their variable dead times are not required, the start and end of the coating process can be specified more precisely.
  • The gear pumps, which are driven synchronously with each other and with the drive of the horizontal conveyor, can drive a ramp at the beginning and at the end of the coating process, which gives the desired start and stop points particularly precisely, which is even in the start phase and in the end phase of the coating ensures high uniformity of the caterpillar from the adhesive and sealing compound.

Die Zahnradpumpen sind zwar Zwangsförderpumpen, in gewissen Grenzen hängt ihre Förderleistung jedoch vom Vordruck ab. In vorteilhafter Weiterbildung der Erfindung ist deshalb vorgesehen, dass der Speicher, aus welchem die Zahnradpumpen die Kleb- und Dichtmasse beziehen, mit einem regelbaren Druckerzeuger in Verbindung steht, denn dadurch ist es möglich, die Zahnradpumpen mit einem optimalen, konstanten Vordruck zu beaufschlagen. Bei den üblicherweise verwendeten Kleb- und Dichtmassen auf der Basis eines Polyisobutylens ist ein Vordruck zwischen 30 und 50 bar günstig.The gear pumps are forced delivery pumps, but their delivery rate depends on the admission pressure within certain limits. In an advantageous development of the invention, it is therefore provided that the memory from which the gear pumps obtain the adhesive and sealing compound is connected to a controllable pressure generator, since this makes it possible to apply an optimal, constant admission pressure to the gear pumps. In the commonly used adhesive and sealing compounds based on a polyisobutylene, a pre-pressure between 30 and 50 bar is favorable.

An embodiment of the invention is shown schematically in the two accompanying drawings.
Figure 1

Die Vorrichtung hat einen Waagerechtförderer 1 in Gestalt eines endlosen Bandes 2, welches über einen waagerechten Stützkörper 3 bewegt wird. Beidseits neben dem Waagerechtförderer 1 befinden sich zwei Düsenköpfe 4 und 5, welche jeweils eine Düse 6 und 7 tragen, welche mit einander zugewandten Mündungen 8 und 9 dicht oberhalb des Förderbandes 2 angeordnet sind. Die Düsenköpfe 4 und 5 sitzen auf einem Gehäuse 10 bzw. 11, welches eine Zahnradpumpe 12 bzw. 13 enthält. Je ein Zahnrad der Zahnradpumpen 12 und 13 sitzt auf einer Welle 14 bzw. 15, welche mittels Zahnriemen 16 und 17 von einem gemeinsamen Elektromotor 18 angetrieben wird, so dass aboluter Synchronlauf gewährleistet ist.The device has a horizontal conveyor 1 in the form of an endless belt 2, which is moved over a horizontal support body 3. On both sides next to the horizontal conveyor 1 there are two nozzle heads 4 and 5, each of which carries a nozzle 6 and 7, which are arranged with mutually facing orifices 8 and 9 just above the conveyor belt 2. The nozzle heads 4 and 5 sit on a housing 10 and 11, which contains a gear pump 12 and 13, respectively. Each gear of the gear pumps 12 and 13 is seated on a shaft 14 or 15, which is driven by a common electric motor 18 by means of toothed belts 16 and 17, so that absolute synchronous operation is ensured.

In den Leitungen 20 und 21 zwischen den Zahnradpumpen 12 und 13 und den Düsen 6 und 7 befindet sich kein Ventil.There is no valve in the lines 20 and 21 between the gear pumps 12 and 13 and the nozzles 6 and 7.

Die beiden Zahnradpumpen 12 und 13 werden aus einem gemeinsamen Speicher 19 gespeist, bei welchem es sich um eine Kolben-Zylinder-Einheit handelt, deren Kolben 22 über ein regelbares Ventil 23 mit Entlüftungsmöglichkeit mit einer hydraulischen Druckquelle 24 verbunden ist. Dadurch kann den Zahnradpumpen 12 und 13 die im Speicher 19 vorhandene Kleb- und Dichtmasse mit einem konstanten Vordruck zugeführt werden. Geht der Vorrat der Kleb- und Dichtmasse im Speicher 19 zur Neige, dann kann der Speicher über eine Speiseleitung 25, in welcher ein Rückschlagventil 26 liegt, mit der Kleb- und Dichtmasse aus einem nicht dargestellten Faß nachgefüllt werden.The two gear pumps 12 and 13 are fed from a common accumulator 19, which is a piston-cylinder unit, the piston 22 of which is connected to a hydraulic pressure source 24 via a controllable valve 23 with the possibility of ventilation. This enables the gear pumps 12 and 13 to store the Existing adhesive and sealant can be supplied with a constant pre-pressure. If the supply of adhesive and sealing compound in storage 19 is running low, then the storage can be refilled with the adhesive and sealing compound from a barrel (not shown) via a feed line 25, in which a check valve 26 is located.

Auf dem Förderband 2 liegt der untere Schenkel eines Abstandhalterrahmens 27, dessen beide Seitenflächen durch die ihnen zugewandten Düsen 6 und 7 beschichtet werden sollen. Der Abstand zwischen dem Abstandhalterrahmen 27 und den Düsen 6 und 7 ist übertrieben dargestellt. In einer praktisch ausgeführten Vorrichtung ist der Abstand der Düsen 6 und 7 zur Anpassung an unterschiedlich breite Abstandhalterprofile in an sich bekannter Weise einstellbar. Auf die Darstellung der Einstellmittel wurde im vorliegenden Fall verzichtet, da sie für die Erfindung nicht wesentlich sind.On the conveyor belt 2 is the lower leg of a spacer frame 27, the two side surfaces of which are to be coated by the nozzles 6 and 7 facing them. The distance between the spacer frame 27 and the nozzles 6 and 7 is shown exaggerated. In a practical device, the distance between the nozzles 6 and 7 can be adjusted in a manner known per se to adapt to spacer profiles of different widths. The setting means were not shown in the present case because they are not essential to the invention.
