Description

Die Erfindung betrifft eine Vorrichtung zum Bestrahlen eines längs­ laufenden Objektes nach dem Oberbegriff des Anspruchs 1.The invention relates to a device for irradiating a longitudinal running object according to the preamble of claim 1.

Zum Aushärten von Kunststoffbeschichtungen, insbesondere in der Ferti­ gung von Glasfasern für optische Zwecke, werden UV-Lampen eingesetzt. Insbesondere zur Aushärtung des Oberflächenschutzes auf optischen Glas­ fasern sind UV-Lampen mit einem Quecksilberdampf-Elektrodenbrenner und einem elliptischen Reflektor im Einsatz. Mit zwei hintereinander ge­ schalteten Lampen wird eine Abzugsgeschwindigkeit der Glasfaser von etwa 80 m/min erreicht. Diese Lampen sind mit Wasser und zusätzlich mit Luft gekühlt.For curing plastic coatings, especially in the ferti glass fibers for optical purposes, UV lamps are used. Especially for hardening the surface protection on optical glass fibers are UV lamps with a mercury vapor electrode burner and an elliptical reflector in use. With two in a row switched lamps will have a pull-off speed of the fiber Reached 80 m / min. These lamps are with water and additionally with air chilled.

Aus der Europäischen Patentanmeldung 2 28 896 ist ein UV-Aushärtesystem bekannt, bei dem eine optische Faser mittels einer UV-Lampe und einem geschlossenen elliptischen Spiegel bestrahlt wird. Um die Abzugsge­ schwindigkeit der Glasfasern zu steigern, müssen mehrere dieser Lampen hintereinander geschaltet werden. Da jedoch die Bauhöhe der gesamten Apparatur einen vorbestimmten Wert nicht überschreiten darf, sind andere Maßnahmen erforderlich.From the European patent application 2 28 896 is a UV curing system known in which an optical fiber by means of a UV lamp and closed elliptical mirror is irradiated. To the deduction Several of these lamps need to increase the speed of the glass fibers be connected in series. However, since the overall height of the entire Equipment must not exceed a predetermined value, others are Measures required.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung anzugeben, welche bei vorgegebener Bauhöhe eine möglichst intensive UV-Bestrahlungs­ intensität auf der Oberfläche eines längslaufenden Objektes realisiert. Diese Aufgabe wird bei einer Vorrichtung der eingangs erwähnten Art nach der Erfindung durch die im Kennzeichen aufgeführten Merkmale gelöst. Weiterbildungen der Erfindung sind in den Unteransprüchen beschrieben. Ein Ausführungsbeispiel der Erfindung wird nachstehend anhand der Zeichnung näher erläutert. The invention has for its object to provide a device which with the given overall height is as intensive as possible UV radiation intensity realized on the surface of a longitudinal object. This object is achieved in a device of the type mentioned the invention solved by the features listed in the license plate. Developments of the invention are described in the subclaims. An embodiment of the invention is described below with reference to the Drawing explained in more detail.  

Die Figur zeigt einen Schnitt durch eine Vorrichtung mit drei Lampen.The figure shows a section through a device with three lamps.

In einem Aluminiumgehäuse, welches zur besseren Zugänglichkeit des Inneren zwei klappbare Gehäuseteile 1 und 2 aufweist, sind unter einem Winkel von 120° drei Quecksilberdampfstrahler eingebaut. Die dazu gehörenden, um 120° versetzten elliptischen Reflektoren 3 für diese Lampe können mit einem Preßwerkzeug einfach hergestellt werden. Die drei Reflektoren 3 sind in entsprechende Halter 6 geklemmt. Diese Halter 6 sorgen für einen festen Sitz und sind leicht zu wechseln. Die drei Strahler 4 sind mit Kontaktschaften versehen und werden wegen des einfachen Ein- und Ausbaus in federnde Kontaktbüchsen geklemmt. Das Lampengehäuse ist nach vorne ausklappbar, um die Wartung einfacher und schneller durchführen zu können. Über die Zu- und Abflüsse 7 wird das Gehäuse mit Wasser gekühlt. Die Kühlluft, die zusätzlich oberhalb und unterhalb des Aluminiumgehäuses zirkuliert, wird über Filter in die Reflektorkammern 9 angesaugt und über Öffnungen in den Reflektoren seitlich in der Mitte des Lampengehäuses abgesaugt. Bei der Beschichtung einer optischen Faser ist es notwendig, sie vor Turbulenzen der Kühlluft zu schützen. Deshalb ist um die Faser ein Faserschutzrohr 5 angebracht. Das Innere des Faserschutzrohres 5 wird in bekannter Weise mit Stick­ stoff gespült. Die Konstruktion der symmetrischen Anordnung der drei Brenner 4 und der drei elliptischen Reflektoren 3 bietet den Vorteil, daß die UV-Strahlen von allen Seiten auf den Brennpunkt treffen und somit die Oberfläche der mit Lack beschichteten Faser rundum gleichmäßig bestrahlt wird.In an aluminum housing, which has two foldable housing parts 1 and 2 for better access to the interior, three mercury vapor lamps are installed at an angle of 120 °. The associated, by 120 ° offset elliptical reflectors 3 for this lamp can be easily manufactured with a press tool. The three reflectors 3 are clamped in corresponding holders 6 . These holders 6 ensure a tight fit and are easy to change. The three emitters 4 are provided with contact shafts and are clamped in resilient contact bushes because of the simple installation and removal. The lamp housing can be folded out to make maintenance easier and quicker. The housing is cooled with water via the inflows and outflows 7 . The cooling air, which additionally circulates above and below the aluminum housing, is drawn into the reflector chambers 9 via filters and is sucked off laterally in the center of the lamp housing via openings in the reflectors. When coating an optical fiber, it is necessary to protect it from turbulence in the cooling air. A fiber protection tube 5 is therefore fitted around the fiber. The inside of the fiber protection tube 5 is rinsed with nitrogen in a known manner. The construction of the symmetrical arrangement of the three burners 4 and the three elliptical reflectors 3 offers the advantage that the UV rays hit the focal point from all sides and thus the surface of the fiber coated with lacquer is irradiated uniformly all round.

Damit ist eine intensive Aushärtung bei hoher Abzugsgeschwindigkeit ge­ geben. Die kompakte Bauweise aus Vollaluminium garantiert die Dichtig­ keit der Lampen und damit eine hohe Arbeitssicherheit. Um Lackzer­ setzungen und damit Verschmutzungen der Faserschutzrohre und der Re­ flektoren zu vermeiden, wird beim Anziehen der Faser mit geringer Abzugsgeschwindigkeit nur ein Brenner eingeschaltet. Bei zunehmender Geschwindigkeit wird automatisch der zweite Brenner und schließlich der dritte Brenner zugeschaltet. Intensive curing at high take-off speed is thus achieved give. The compact design made of full aluminum guarantees the tightness lamps and thus a high level of occupational safety. To Lackzer settlement and thus contamination of the fiber protection tubes and the Re Avoiding flectors becomes less when tightening the fiber Withdrawal speed only one burner switched on. With increasing Speed automatically becomes the second burner and finally the third burner switched on.  

Statt drei Lampen im Abstand von 120° kann man auch vier Lampen mit entsprechenden Reflektoren in einem Winkelabstand von 90° vorsehen. Auch zwei Lampen im Abstand von 180° sind denkbar. Um eine noch gleich­ mäßigere Bestrahlung zu gewährleisten, können die Lampen auch mit dem Lampengehäuse gedreht bzw. geschwenkt werden. Die Lampen werden dem­ entsprechend über Schleifringe mit Strom versorgt.Instead of three lamps at a distance of 120 °, you can also use four lamps provide appropriate reflectors at an angle of 90 °. Also two lamps at a distance of 180 ° are conceivable. To be one more To ensure more moderate radiation, the lamps can also be used with the Lamp housing can be rotated or swiveled. The lamps are the accordingly supplied with power via slip rings.

Die Vorteile der Erfindung liegen darin, daß höhere Abzugsgeschwindig­ keiten möglich sind. Es findet eine bessere Aushärtung des Oberflächen­ schutzes statt. Der Oberflächenschutz ist z.B. UV-aushärtbares Acrylat (Polyester- und/oder Urethanacrylat). Durch die intensive Kühlung haben auch die Brenner eine hohe Lebenserwartung und die IR-Bestrahlung der Faser wird reduziert, so daß der abgedampfte Monomeranteil ebenfalls drastisch reduziert wird. Hierdurch werden die Wartungsintervalle (Austausch des Quarzglasschutzrohres (Faserschutzrohr)) verlängert.The advantages of the invention are that higher withdrawal speeds possible. There is a better hardening of the surface protection instead. The surface protection is e.g. UV curable acrylate (Polyester and / or urethane acrylate). Due to the intensive cooling even the burners have a high life expectancy and the IR radiation of the Fiber is reduced so that the evaporated monomer portion also is drastically reduced. This will change the maintenance intervals (Replacement of the quartz glass protection tube (fiber protection tube)) extended.
