Description
Die Erfindung betrifft eine Vorrichtung zum Trocknen von Gegenständen nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a device for drying articles according to the preamble of patent claim 1.
Unter ”Trockenvorrichtung” werden hier alle Vorrichtungen verstanden, in denen ein Beschichtungsmaterial vom Zustand nach dem Auftragen in den Endzustand überführt wird, sei es durch die Entfernung von Lösemitteln, Aufschmelzen, Vernetzen oder Ähnlichem.By "drying device" is meant here all devices in which a coating material is transferred from the state after application to the final state, be it by the removal of solvents, melting, crosslinking or the like.
In jüngster Zeit gewinnen zunehmend Lacke Bedeutung, die in einer Inertgasatmosphäre, ggfs unter elektromagnetischer Bestrahlung, z. B. unter UV-Licht, ausgehärtet werden müssen, um unerwünschte Reaktionen mit Bestandteilen der normalen Atmosphäre, insbesondere mit Sauerstoff, zu verhindern. Diese neuartigen Lacke zeichnen sich durch eine sehr große Oberflächenhärte und durch kurze Vernetzungszeiten aus. Der letztgenannte Vorteil setzt sich bei Lackieranlagen, die im kontinuierlichen Durchlauf betrieben werden, unmittelbar in geringere Anlagenlängen um, was selbstverständlich zu erheblich niedrigeren Investitionskosten führt.In recent years, increasingly gaining coatings importance in an inert gas atmosphere, if necessary under electromagnetic radiation, for. B. under UV light, must be cured to prevent unwanted reactions with components of the normal atmosphere, especially with oxygen. These novel coatings are characterized by a very high surface hardness and short curing times. The latter advantage is in paint shops, which are operated in a continuous cycle, directly into smaller plant lengths, which of course leads to significantly lower investment costs.
Bei vom Markt her bekannten Vorrichtungen der eingangs genannten Art, wie sie beispielsweise aus der
Für verhältnismäßig kleine Volumina ist auch bekannt, dass Inertgas mit Hilfe einer Kolben-Zylinder-Einheit von einer Bereitstellungseinrichtung in eine vorgesehene Kammer überführt wird. Ein Beispiel hierfür ist die
Auch die
Aufgabe der vorliegenden Erfindung ist es, eine Vorrichtung der eingangs genannten Art so auszugestalten, dass höhere Durchsatzzahlen erzielt werden können.Object of the present invention is to provide a device of the type mentioned in such a way that higher throughputs can be achieved.
Diese Aufgabe wird erfindungsgemäß mit den im Patentanspruch 1 angegebenen Mitteln gelöst.This object is achieved by the means specified in claim 1.
Erfindungsgemäß kann die Zeit, welche der Gegenstand in der Kammer zum Trockenvorgang verbringen muss, dazu genutzt werden, auch aus einer verhältnismäßig unergiebigen Inertgasquelle ein solches Volumen von Inertgas anzusammeln, wie dies zum Befüllen der Kammer erforderlich ist. Hat der fragliche Gegenstand die Kammer nach Abschluss des Trockenprozesses verlassen, kann das angesammelte Inertgas durch eine entsprechend hohe, auf den Kolben ausgeübte Kraft in sehr kurzer Zeit in die Kammer eingedrückt werden. Die Kammer steht somit in kurzer Zeit für den nächsten Trockenzyklus zur Verfügung, was sich günstig auf die Kapazität der Anlage auswirkt.According to the invention, the time which the article must spend in the chamber for the drying process can be used to accumulate such a volume of inert gas also from a relatively inefficient inert gas source, as is required for filling the chamber. If the object in question has left the chamber after completion of the drying process, the accumulated inert gas can be pressed into the chamber in a very short time by a correspondingly high force exerted on the piston. The chamber is therefore available in a short time for the next drying cycle, which has a favorable effect on the capacity of the system.
In vielen Fällen, insbesondere bei Verwendung von Stickstoff oder CO2 als Inertgas, umfasst die Einrichtung zur Bereitstellung des Inertgases einen Vorratstank für flüssiges Inertgas und eine Heizeinrichtung zum Verdampfen des Inertgases. Bei dieser Ausführungsform der Vorrichtung kommen die Vorteile der vorliegenden Erfindung besonders zur Geltung: Es ist dann nämlich möglich, die Heizeinrichtung, mit welcher das flüssige Inertgas verdmpft wird, verhältnismäßig klein zu dimensionieren.In many cases, particularly when nitrogen or CO 2 is used as the inert gas, the inert gas supply means comprises a liquid inert gas storage tank and a heater for vaporizing the inert gas. In this embodiment of the device, the advantages of the present invention are particularly effective: it is then possible to dimension the heating device with which the liquid inert gas is vaporized to be relatively small.
Vorzugsweise ist die mindestens eine Kammer eine UV-Bestrahlungskammer. In der Uv-Bestrahlungskammer werden die höchsten Anforderungen an die Reinheit der Inertgasatmosphäre gestellt, so dass es sinnvoll ist, das Inertgas direkt in die UV-Bestrahlungskammer einzubringen.Preferably, the at least one chamber is a UV irradiation chamber. In the UV irradiation chamber, the highest requirements are placed on the purity of the inert gas atmosphere, so that it makes sense to introduce the inert gas directly into the UV irradiation chamber.
Besonders vorteilhaft ist die Vorrichtung dann einzusetzen, wenn sie zum Trocknen von lackierten Fahrzeugkarosserien ausgebildet ist. Bei den dort notwendigen großen Kammervolumina macht sich die Zeitersparnis besonders bemerkbar.It is particularly advantageous to use the device when it is designed to dry painted vehicle bodies. With the large chamber volumes required there, the time savings are particularly noticeable.
