Description
Die Erfindung betrifft eine Energietransmitter als Bestandteil einer Beschichtungs- und/oder Trockenanlage, insbesondere für eine Lackbeschichtung nach dem Oberbegriff des Anspruchs 1.The invention relates to an energy transmitter as part of a coating and / or drying plant, in particular for a paint coating the preamble of claim 1.
Bei herkömmlichen Lackierungsprozessen werden unterschiedliche Lackmaterialien zum Teil in mehreren Schichten, wie Pulverlacke, Füller, Basislacke, Klarlacke, etc. verwendet, die bei Reaktionstemperaturen von ca. 80° bis ca. 200° aufgeschmolzen bzw. getrocknet werden müssen. In allgemein bekannten Beschichtungsanlagen, die für serienmäßige Lackierungen vieler Bauteile, wie beispielsweise von Gehäusen, Karosserien, Metallstrukturteilen, etc. ausgelegt sind, werden konventionelle Umluft-Trocknungen mit Heißluft durchgeführt, die enorme Energiekosten und lange Trocknungszeiten erfordern. Als Energietransmitter ist hier die durch Heizelemente aufgeheizte Heißluft eingesetzt. Bei einem kontinuierlichen Transport der Bauteile durch Trocknungs-Tunnels haben diese eine große Länge, so dass entsprechend aufwendige Konstruktionen in großen Gebäudekomplexen erforderlich sind. Neben diesen Beschichtungs- und Lackieranlagen mit konventionellen herkömmlichen Umlufttrocknungen durch Heißluft sind auch mehrstufige Verfahren in Verbindung mit anderen Energietransmittern bekannt, mit denen Energie in der Lackbeschichtung zum Zwecke des Aufschmelzens und/oder Trocknens aufgebracht wird: Different coating materials are used in conventional painting processes partly in several layers, such as powder coatings, fillers, basecoats, Clear varnishes, etc. are used, which at reaction temperatures of about 80 ° to about 200 ° must be melted or dried. In well-known Coating systems that are used for standard painting of many components, such as housings, bodies, metal structural parts, etc. designed conventional convection drying is carried out with hot air, which require enormous energy costs and long drying times. As The hot air heated by heating elements is used here as an energy transmitter. With continuous transport of the components through drying tunnels these have a large length, so that they are correspondingly complex Constructions in large building complexes are required. Besides these Coating and painting systems with conventional conventional circulating air drying hot air also connects multi-stage processes known with other energy transmitters with which energy in the paint coating applied for the purpose of melting and / or drying becomes:
Bei einer bekannten Lackieranlage (DE 198 57 940 C1) wird eine kombinierte UV/IR-Härtung ausgenutzt, wobei in mehreren aufeinanderfolgenden Bestrahlungsintervallen auszuhärtendes Lackmaterial mit IR- und mit UV-Strahlung abwechselnd bestrahlt wird. Hierzu ist ein spezielles teures Lackmaterial erforderlich, wobei die Anwendung bevorzugt bei Reparaturlackierungen liegt.In a known painting system (DE 198 57 940 C1) a combined one is used Utilized UV / IR curing, taking place in several successive irradiation intervals Paint material to be hardened with IR and UV radiation is alternately irradiated. This requires a special, expensive paint material, the application is preferably for refinishing.
Weiter ist eine Lackieranlage bekannt, bei der für die Lacktrocknung ein zweistufiges Trocknungsverfahren eingesetzt wird (DE 195 03 775 C1),wobei in der ersten Trocknungsstufe als Energietransmitter Infrarot-Strahler verwendet werden. Ein Problem bei diesen Infrarot-Strahlern besteht darin, dass die Strahlungsintensität und damit die effektive Energiebeaufschlagung im Beschichtungsmaterial mit den Quadrat des Abstandes abnimmt. Daher sind hier die Infrarot-Strahler in ihrer Gestalt dem zu trocknenden Gegenstand konturengenau angepasst und mittels gesteuerter Stellvorrichtungen in der Art von Robotern auf einen geringen Abstand an die Oberfläche heranbringbar, so dass zu Erhöhung der Effektivität ein geringer Zwischenspalt verbleibt. Dies stellt einen erheblichen apparativen Aufwand dar. Dadurch ist insbesondere bei stärker strukturierten Bauteilen ersichtlich ein kontinuierlicher Transport durch eine Trocknungseinrichtung nicht möglich, da der Gegenstand während der ersten Trocknungsstufe am Ort der herangeführten Infrarotstrahler örtlich festgehalten werden muss. In einer zweiten Trocknerkabine wird dann eine Nachtrocknung als zweite Trocknungsstufe mit überwiegend stationären Infrarot-Strahlern durchgeführt, wofür wiederum ein erheblicher Zeitaufwand erforderlich ist.Furthermore, a painting system is known in which a two-stage for drying the paint Drying process is used (DE 195 03 775 C1), in which first drying stage can be used as an energy transmitter infrared radiator. A problem with these infrared emitters is that the radiation intensity and thus the effective energy load in the coating material decreases with the square of the distance. So here are the The shape of the infrared emitter precisely matches the object to be dried adapted and by means of controlled actuators in the manner of robots can be brought to the surface at a short distance, so that too Increasing effectiveness leaves a small gap. This represents one considerable expenditure on equipment. This makes it more powerful structured components can be seen a continuous transport through a Drying facility not possible because the item was removed during the first Drying level recorded locally at the location of the infrared heaters must become. After-drying is then carried out in a second dryer cabin as a second drying stage with predominantly stationary infrared emitters carried out, which in turn requires a considerable amount of time.
Weiter ist eine Lackieranlage bekannt (DE 38 14871 A1), bei der ausschließlich eine Infrarottrocknung eingesetzt ist, die mit einer Strahlungsfrequenz im Nahen-Infrarot (NIR) bei 1,0 bis 4,0 µm arbeitet. Auch hier treten die zuvor genannten Probleme für eine effiziente Energieaufbringung auf. Zudem besteht das Problem, dass verdeckte Bereiche, wie beispielsweise hinterschnittene Bereich auf die die IR-Strahlung nicht unmittelbar auftrifft, nur wenig erwärmt und ausgehärtet werden.Furthermore, a painting system is known (DE 38 14871 A1), in which only an infrared drying is used, which with a radiation frequency in Near-infrared (NIR) works at 1.0 to 4.0 µm. Here, too, the aforementioned ones occur Problems for efficient energy supply. There is also the problem that hidden areas, such as undercut Area where the IR radiation does not hit directly, only slightly warmed and be cured.
Zusammenfassend ist festzustellen, dass bei den bisher bekannten Beschichtungs- und Lackieranlagen die Aufschmelzung und/oder Aushärtung von Beschichtungsmaterialien einen sehr hohen Aufwand an Energie und Zeit erfordert. Dieser Aufwand ist auch dadurch bedingt, dass ein Bauteil als Träger des Beschichtungsmaterials, insbesondere bei einem gut wärmleitenden Metallbauteil auch selbst ebenso wie die Umgebungsluft auf die erforderliche Temperatur des Beschichtungsmaterials, aufgeheizt werde muss, damit das angrenzende Beschichtungsmaterial die erforderliche hohe Temperatur annehmen kann. Bei Bauteilen mit größeren Materialmassen ergibt sich dann weiter das Problem, dass die mit großem Energieaufwand aufgeheizten Bauteile für ein weiteres Handling zeitraubend wieder abgekühlt werden müssen, wobei für eine aktive Kühlung wiederum ein hoher Energieverbrauch erforderlich ist.In summary, it can be stated that the previously known coating and painting systems the melting and / or curing of coating materials requires a very high expenditure of energy and time. This effort is also due to the fact that a component as the carrier of the Coating material, especially in the case of a metal component that is a good conductor of heat as well as the ambient air to the required temperature of the coating material must be heated so that the adjacent Coating material assume the required high temperature can. In the case of components with larger masses of material, this then continues the problem that the components heated up with great energy expenditure for another handling has to be cooled down in a time-consuming manner, whereby for active cooling in turn requires high energy consumption.
Aufgabe der Erfindung ist es daher einen Energietransmitter als Bestandteil einer Beschichtungs- und/oder Trockenanlage, insbesondere für eine Lackbeschichtung zu schaffen mit dem wesentliche Prozessenergieeinsparungen möglich sind.The object of the invention is therefore an energy transmitter as a component a coating and / or drying system, in particular for a paint coating to create with the essential process energy savings possible are.
Diese Aufgabe wird mit den Merkmalen des Anspruchs 1 gelöst.This object is achieved with the features of claim 1.
Gemäß Anspruch 1 umfasst der Energietransmitter wenigstens zwei Transmitter-Flächenelemente als Antennenelemente. Jedes der Transmitter-Flächenelemente weist eine Glasträgerplatte auf, die auf einer Glasrückfläche eine Abstrahlschicht trägt und deren gegenüberliegende freie Glasvorderfläche auf eine Position für ein zu trocknendes Objekt oder eine Oberfläche eines Bauteils mit aufgetragenem Beschichtungsmaterial gerichtet ist. Im Abstand und etwa parallel zu der Glasrückfläche und wenigstens in deren Größe ist ein Flächenreflektor aus Metallmaterial angeordnet. According to claim 1, the energy transmitter comprises at least two transmitter surface elements as antenna elements. Each of the transmitter sheet elements has a glass carrier plate that has a radiation layer on a glass back surface carries and their opposite free glass front surface a position for an object to be dried or a surface of a component is directed with applied coating material. In the distance and approximately parallel to the glass rear surface and at least in its size is a surface reflector arranged from metal material.
Die jeweilige Abstrahlschicht ist zur Abgabe einer elektromagnetischen Strahlung in einem Frequenzband ausgelegt, wobei das Frequenzband wenigstens charakteristische Eigenfrequenzen im Ultrarot eines zu trocknenden Objekts oder Beschichtungsmaterials überdecken muss. Solche molekularen Eigenfrequenzen liegen insbesondere im Ultrarotbereich von ca. 10-9 bis 10-12 Hertz. Die Abstrahlschicht ist mittels einer Steuereinrichtung zur Abgabe des wenigstens einen Frequenzbandes anregbar, so dass Eigenfrequenzen des zu trocknenden Objekts oder des Beschichtungsmaterials in Resonanz anregbar sind. Dabei sucht sich die Anordnung die zutreffende korrespondierende Resonanzfrequenz zu einer Eigenfrequenz aus dem abgestrahlten Frequenzband für eine gezielte Energiebeaufschlagung mit hoher Energiedichte entsprechend üblicher Resonanzvorgänge heraus. Durch eine gezielte Anpassung des abgestrahlten Frequenzbandes an die jeweils messtechnisch ermittelbaren Eigenfrequenzen, insbesondere von Lackmaterialien ist somit ein Energieeintrag unmittelbar in diese Materialien mit hoher Energiedichte möglich, ohne dass angrenzende Umgebungsbereiche, insbesondere Bauteilträgerbereiche auf hohe Temperaturen mitaufgeheizt werden bzw. nur wenig mitaufgeheizt werden. Zudem tritt hier im Gegensatz zu herkömmlichen IR-Strahlern nur eine minimale Temperaturerhöhung in der Abstrahlschicht der Energietransmitter auf, die hier als Antennenelemente arbeiten. Da die zu beschichtenden Bauteile selbst nicht zwangsläufig auf hohe Temperaturen mitaufgeheizt werden müssen, können sonst nach einer Lacktrocknung erforderliche Abkühlprozesse eingespart oder zumindest erheblich reduziert werden.The respective radiation layer is designed to emit electromagnetic radiation in a frequency band, the frequency band having to cover at least characteristic natural frequencies in the infrared of an object or coating material to be dried. Such molecular natural frequencies are in particular in the ultra-infrared range from approx. 10 -9 to 10 -12 Hertz. The radiation layer can be excited by means of a control device to emit the at least one frequency band, so that natural frequencies of the object to be dried or the coating material can be excited in resonance. The arrangement looks for the appropriate corresponding resonance frequency to a natural frequency from the emitted frequency band for targeted energy application with high energy density in accordance with conventional resonance processes. Through a targeted adaptation of the emitted frequency band to the natural frequencies that can be determined by measurement, in particular of coating materials, energy input directly into these materials with a high energy density is possible without adjacent areas, in particular component carrier areas, being heated up to high temperatures or being only slightly heated up. In addition, in contrast to conventional IR emitters, there is only a minimal increase in temperature in the radiation layer of the energy transmitters, which work here as antenna elements. Since the components to be coated themselves do not necessarily have to be heated to high temperatures, cooling processes required after coating drying can otherwise be saved or at least considerably reduced.
Insgesamt können erfindungsgemäß somit Beschichtungs- und/oder Trockenanlagen aufgebaut werden, die mit erheblich geringerem Energie- und Zeitaufwand betrieben werden können.Overall, coating and / or drying systems can thus be used according to the invention can be built with much less energy and time can be operated.
Durch umfangreiche Versuche wurde ermittelt, dass insbesondere der angegebene Aufbau der Transmitter-Flächenelemente in Verbindung mit dem Flächenreflektor und der angegebenen Abstrahlrichtung zu einer wesentlichen Effektivitätssteigerung führt.Extensive tests have shown that in particular the specified Structure of the transmitter surface elements in connection with the surface reflector and the specified direction of radiation for a significant increase in effectiveness leads.
In einer konkreten Anordnung der Transmitter-Flächenelemente nach Anspruch
2 sind diese rechtwinkelig oder quadratisch mit ebenen Glasflächen
ausgebildet und insgesamt in wenigstens einer Ebene vorzugsweise in einander
gegenüberliegenden Ebenen angeordnet. Dadurch ergibt sich ein einfacher
konstruktiver Aufbau mit vorteilhaft großflächigen Gesamtabstrahlflächen
für eine effektive Energiebeaufschlagung. In Versuchen hat sich gezeigt, dass
eine besonders effektive Abstrahlung mit Transmitter-Flächenelementen mit
Kantenlängen von ca. 20 cm bis 80 cm, bevorzugt von ca. 40 cm möglich ist.In a specific arrangement of the transmitter surface elements according to
Mit den Merkmalen des Anspruchs 3 kann eine geschlossene, gasdichte
Frontebene bei Bedarf hergestellt werden.With the features of
In einer besonders bevorzugten Weiterbildung nach Anspruch 4 bilden die
Ebenen der Transmitter-Flächenelemente Innenwände eines Tunnels und sind
an dessen Seitenwänden und/oder an der Deckenwand und/oder an der Bodenwand
angeordnet. Durch einen solchen Tunnel hindurch können insbesondere
Bauteile für eine Lacktrocknung automatisiert transportiert werden.In a particularly preferred development according to
Mit den Merkmalen des Anspruchs 5 wird eine Abstrahlschicht beansprucht,
die für die Abstrahlung der angegebenen Frequenzbänder in hohem Maße geeignet
ist. Anspruch 6 ist dazu auf weitere Konkretisierungen und vorteilhafte
Ausgestaltungen gerichtet.With the features of
Nach Anspruch 7 weisen die Transmitter-Flächenelemente jeweils an gegenüberliegenden
Seitenbereichen der mit der Abstrahlschicht ausgerüsteten
Glasrückflächen elektrische Leiter auf, wobei alle Transmitter-Flächenelemente
in Parallelschaltung mit einem Oberwellengenerator der Steuereinrichtung verbunden
sind. Der Oberwellengenerator umfasst einen elektrischen Baustein,
welcher bei Ansteuerung mit einer Ansteuerschwingung eine steile Stromanstiegsgeschwindigkeit
aufweist und damit zur Erzeugung eines hohen Oberwellenanteiles
geeignet ist. Diese Leiter werden vorzugsweise als Kupferfolienbänder
ausgebildet, wobei eine Ankopplung an die Abstrahlschicht kapazitiv
oder induktiv erfolgt. Als elektronischer Baustein mit den angegebenen Eigenschaften
eignet sich ein Triac oder Doppel-MOSFET oder gegebenenfalls auch
ein ultraschneller Schalter. Die Abstrahlschicht wirkt bei einer solchen Anregung
in der Art eines Frequenztransformators, wobei relativ kleinere Anregungsfrequenzen
zu den hohen Abstrahlfrequenzen mit dem angegebenen
Ultrarot-Frequenzband führen.According to
Mit der Weiterbildung nach Anspruch 8 wird vorgeschlagen, eine Anzahl der
Transmitter-Flächenelemente mit einer Frequenz im Megahertzbereich und die
anderen Transmitter-Flächenelemente mit einer Frequenz im Gigahertzbereich
anzuregen. Durch die vorstehende Funktion der Abstrahlschicht als Frequenzumsetzer
bzw. Frequenzmultiplikator zu höheren Frequenzen bezüglich der jeweiligen
Anregungsfrequenz ist mit einer solchen aufgeteilten Anregung der
Transmitter-Flächenelemente eine weite Überdeckung von Eigenfrequenzbereichen
möglich, falls dies für konkrete Anwendungen erforderlich ist. Dies
kann beispielsweise zutreffen, wenn als Beschichtungsmaterial Materialmischungen
verwendet sind, die relativ weit auseinanderliegende, für die erfindungsgemäßen
Resonanzzwecke geeignete Eigenfrequenzen aufweisen.With the development according to
Nach Anspruch 9 soll der Flächenreflektor aus wenigstens einem tragfähigen
Metallblech gebildet sein, an dem über Isolationselemente die Transmitter-Flächenelemente
gehalten sind. Der Abstand zwischen dem Flächenreflektor und
den Transmitter-Flächenelementen liegt für eine optimale Wirkung bei ca. 1 cm
bis 10 cm vorzugsweise ca. bei 4 cm. Dieser Abstand ist einfach durch eine
entsprechende Ausgestaltung der Isolationselemente vorgebbar. Eine solche
Anordnung ergibt einen einfachen und kostengünstigen Aufbau. Der Flächenreflektor
selbst kann wiederum ohne das Erfordernis einer elektrischen Installation
auf geeigneten Traggestellen oder Tragwänden montiert sein. Die Abstrahlschicht
liegt bei einer solchen Anordnung im Zwischenspalt zwischen den
Transmitter-Flächenelementen und dem Flächenreflektor und ist damit vorteilhaft
auch bei einem rauen Betrieb gegen mechanische und gegebenenfalls
chemische Einflüsse geschützt. Die unbeschichtet nach außen gerichtete
Glasfläche ist dagegen weitgehend unempfindlich und kann insbesondere einfach
sauber gehalten werden, was für eine effektive und störungsfreie Abstrahlung
wesentlich ist. Die unbeschichteten Glasflächen werden auch von den üblicherweise
in Lackieranlagen bei Aufschmelzungen und Trocknungen auftretenden
Chemikalien, wie beispielsweise Lösungsmitteldämpfen etc. nicht angegriffen.
Hohe, störungsfreie Standzeiten mit geringen Wartungsaufwand sind
somit gewährleistet.According to
Mit Anspruch 10 wird zudem der Aufbau einer automatisiert betreibbaren Lackbeschichtungsanlage
beansprucht, wobei in einer ersten Einrichtung als erster
Station das Beschichtungsmaterial in flüssiger oder pulverförmiger oder granulatförmiger
Form aufgetragen wird. Dies kann vorteilhaft in an sich bekannter
Weise gemäß Anspruch 10 elektrostatisch und/oder durch Aufspritzen erfolgen.
Eine zweite Einrichtung umfasst in einer zweiten Station den vorstehend
beschriebenen Energietransmitter, wobei damit das beschichtungsfreie Material,
vorzugsweise ein Pulverlackmaterial, aufschmelzbar und/oder trockenbar
ist. Dadurch werden mit sehr geringem Energieaufwand und kurzen Behandlungszeiten
einwandfreie, gut haltende Beschichtungen erreicht. Zu beschichtende
Bauteile, wie Metallstrukturteile, Karosserien oder Metallgehäuse können
in vorzugsweise tunnelartig aufgebauten Anlagen kontinuierlich oder gegebenenfalls
taktweise mittels Transporteinrichtungen, wie z. B. mit Förderbänder
automatisch transportiert werden.With
Als besonders geeignet haben sich nach Anspruch 12 Pulverlacke mit Eigenfrequenzen im Bereich der Wellenzahlen von ca. 1000 bis 1800 cm-1 erwiesen, die gemäß Anspruch 13 auf Bauteilen aus Metallmaterial aufgebracht werden. Powder coatings with natural frequencies in the range of the wave numbers from approximately 1000 to 1800 cm -1 , which are applied according to claim 13 to components made of metal material, have proven to be particularly suitable.

In der Fig. 1 ist schematisch und perspektivisch ein Energietransmitter 1 als
Bestandteil einer Beschichtungs- und Trockenanlage 2 für eine Lackbeschichtung
gezeigt. Diese Beschichtungs- und Trockenanlage 2 weist in einer hier
nicht dargestellten ersten Station eine erste Einrichtung zum Auftrag eines
z. B. Pulverlacks als Beschichtungsmaterial auf eine Oberfläche eines zu beschichtenden
Bauteils 3, z. B. eine Kraftfahrzeugkarosserie, auf. Der Pulverlack
weist Eigenfrequenzen im Bereich der Wellenzahlen von ca. 1000 bis
1.800 cm-1 auf und wird in der ersten Einrichtung elektrostatisch auf das Bauteil
3 aufgetragen. Das Bauteil 3 mitsamt dem elektrostatisch anhaftenden Pulverlack
wird mittels einer Transporteinrichtung 4 kontinuierlich oder taktweise
durch die hier nicht dargestellte erste Einrichtung gefördert und gelangt nach
Durchlaufen dieser ersten Station zu einer in der Fig. 1 schematisch und perspektivisch
dargestellten zweiten Station 5, die der ersten Station nachgeordnet
ist und einen Tunnel 7 umfasst, durch den hindurch das Bauteil 3 mittels der
Transporteinrichtung 4 in der gewünschten Weise kontinuierlich oder taktweise
gefördert wird.1 shows schematically and in perspective an energy transmitter 1 as part of a coating and drying
Wie dies insbesondere aus der Fig. 1 ersichtlich ist, sind an den Innenwänden
des Tunnels 7, d. h. an den Seitenwänden 8 und an den Deckenwänden 9 jeweils
eine Mehrzahl von den Energietransmitter 1 bildenden Transmitter-Flächenelementen
10 angeordnet, die vorzugsweise im Wesentlichen aneinander
angrenzen und z. B. einen schmalen Spalt zwischen sich ausbilden, in den,
wie dies in der Fig. 2 schematisch dargestellt ist, ein elastisch isolierendes
Dichtband 21 eingesetzt werden kann. Dadurch wird eine geschlossene, gasdichte
Frontebene erreicht. Diese Transmitter-Flächenelemente sind hier beispielhaft
in etwa rechteckförmig ausgebildet und weisen jeweils eine Glasträgerplatte
11 auf, wie dies insbesondere aus den Fig. 2 und 3, die vergrößerte
schematische Detaildarstellungen zeigen, ersichtlich ist. Diese Glasträgerplatte
11 trägt auf einer Glasrückfläche 12 eine in der Darstellung der Fig. 3 schematisch
durch eine Punktstruktur dargestellte Abstrahlschicht 13. An gegenüberliegenden
Seitenbereichen dieser Glasrückfläche 12 sind auf der Abstrahlschicht
13 elektrische Leiter 14, 15 angeordnet, die in Parallelschaltung mit
einem Oberwellengenerator einer in der Fig. 3 lediglich äußerst schematisch
und beispielhaft dargestellte Steuereinrichtung 16 verbunden sind. Dieser
Oberwellengenerator der Steuereinrichtung 16 umfasst einen elektrischen
Baustein, der bei einer Ansteuerung mit einer Ansteuerschwingung eine steile
Stromanstiegsgeschwindigkeit entsprechend einer steilen Anstiegsflanke aufweist
und damit zur Erzeugung eines hohen Oberwellenanteils geeignet ist.
Dadurch können die Transmitter-Flächenelemente 10 mit einer Frequenz im
Megahertzbereich oder mit einer Frequenz im Gigahertzbereich angeregt werden.As can be seen in particular from FIG. 1, are on the inner walls

sind aus einem tragfähigen Metallblech gebildet, an dem über in der Fig. 2 dargestellte
Isolationselemente 19 die Transmitter-Flächenelemente 10 gehalten
sind. Der Abstand zwischen dem Flächenreflektor 20 und dem Transmitter-Flächenelementen
10 beträgt dabei z. B. in etwa zwischen 1 cm bis zu 10 cm.The
