Abstract
Description
Die Erfindung geht aus von einer Infrarot-Strahlungsanlage aus mehreren gleichartig ausgebildeten Heizelementen, von denen jedes einen Reflektor und einen in diesem gelagerten Heizkörper aufweist, wobei die Heizelemente aneinandergereiht angeordnet und entlang ihrer Längsränder durch Kuppelglieder miteinander schwenkbar verbunden sind. Eine Infrarot-Strahlungsanlageder eingangs beschriebenen Art ist aus der US-A-2 627 014 bekannt. Es ist ein Gehäuse aus stranggepreßtem Aluminiumprofil vorgesehen, welches den Reflektor und den in dem Reflektor angeordneten Heizkörper aufnimmt. Entlang den Längsrändern des Gehäuses sind Kuppelglieder vorgesehen, die im Sinne einer Nut/Feder- Verbindung eine Befestigung mehrerer Gehäuse miteinander erlauben. Im Bereich der Kuppelglieder ist das Gehäuse derart ausgeführt, so daß einerseits zwischen zwei verbundenen Gehäusen eine Anlage entsteht und andererseits ein gewisser Schwenkbereich erreicht wird. Weiterhin sind eine Vielzahl von zusätzlichen Befestigungselementen einerseits für das Heizelement und andererseits für das Gehäuse selbst vorgesehen. Vorteilhaft ist hier bereits die Möglichkeit gegeben, mehrere Heizelemente miteinander verbinden zu können und somit die resultierende Heizleistung entsprechend den jeweiligen Verhältnissen anpassen zu können. Nachteilig ist jedoch, daß diese aus mehreren Heizelementen gebildete Infrarot-Strahlungsanlage sich nur sehr beschränkt an die Geometrie der Bestrahlungsgüter anpassen läßt. Weiterhin nachteilig ist, daß die einzelnen Heizelemente aus einer Vielzahl von teilweise recht kompliziert aufgebauten Teilen besteht und somit in der Herstellung aufwendig ist.The invention is based on an infrared radiation system comprising a plurality of heating elements of the same design, each of which has a reflector and a heating element mounted therein, the heating elements being arranged in a row and being pivotally connected to one another along their longitudinal edges by coupling elements. An infrared radiation system of the type described in the opening paragraph is known from US-A-2 627 014. A housing made of extruded aluminum profile is provided, which receives the reflector and the radiator arranged in the reflector. Coupling elements are provided along the longitudinal edges of the housing, which allow a plurality of housings to be fastened to one another in the sense of a tongue and groove connection. In the area of the coupling elements, the housing is designed such that, on the one hand, a system is created between two connected housings and, on the other hand, a certain swivel range is achieved. Furthermore, a large number of additional fastening elements are provided on the one hand for the heating element and on the other hand for the housing itself. Advantageously, there is already the possibility here of being able to connect a plurality of heating elements to one another and thus to be able to adapt the resulting heating power in accordance with the respective conditions. However, it is disadvantageous that this infrared radiation system, which is formed from a plurality of heating elements, can only be adapted to the geometry of the radiation goods to a very limited extent. A further disadvantage is that the individual heating elements consist of a large number of parts, some of which are quite complicated, and are therefore expensive to manufacture.
Aus der DE-B-20 52 304 ist eine Infrarot-Strahlungsanlage bekannt, bei der für jeden keramischen Heizkörper ein, dessen Abmessungen angepaßter Reflektor vorgesehen ist, der die Heizkörper einseitig umschließt. Je nach der erforderlichen Heizleistung sind die elektrischen Heizkörper und die dazugehörigen Reflektoren verschieden groß, was eine verhältnismäßig große Lagerhaltung für die verschiedenen Typen von Infrarot-Strahlungsanlagen erforderlich macht. Außerdem ergeben sich mit den bekannten Heizkörpern und Reflektoren Schwierigkeiten bei großflächigen Anlagen, insbesondere bei von einer ebenen Fläche abweichenden Werkstückoberfläche.From DE-B-20 52 304 an infrared radiation system is known in which a reflector is provided for each ceramic heating element, the dimensions of which are adapted and which surrounds the heating element on one side. Depending on the heating power required, the electric radiators and the associated reflectors are of different sizes, which necessitates a relatively large inventory for the different types of infrared radiation systems. In addition, there are difficulties with the known radiators and reflectors in large-area systems, in particular in the case of a workpiece surface deviating from a flat surface.
Aufgabe der Erfindung ist es, diese Mängel zu beheben und eine Infrarot-Strahlungsanlage zu schaffen, die sich an die jeweils erforderlichen Heizleistungen und an die verschiedensten Geometrien der Bestrahlungsgüter in einfachster Weise anpassen läßt, ohne daß eine umfangreiche Lagerhaltung erforderlich wird.The object of the invention is to remedy these shortcomings and to provide an infrared radiation system which can be adapted in a very simple manner to the heating outputs required and to the most varied geometries of the radiation goods, without extensive storage being necessary.
Dies wird erfindungsgemäß dadurch erreicht, daß die Heizkörper als keramische Heizkörper ausgebildet sind, daß die Reflektoren aus Edelstahlblech bestehen, als unmittelbare Träger für den Heizkörper dienen und schräg gestellte Wände aufweisen, an deren längsverlaufenden Rändern die Kupplungsglieder in Form von Scharnieren aus Buchsen und Gelenk- oder Tragbolzen vorgesehen sind. Es wird hier also von der im Stand der Technik bekannten Zweiteilung zwischen Reflektor und Gehäuse abgegangen und der Reflektor als unmittelbaren Träger für den Heizkörper verwendet. Dadurch wird eine wesentliche Vereinfachung der einzelnen Heizelemente erreicht. Die Reflektoren weisen schräggestellte Wände auf, an deren längsverlaufenden Rändern dann die Kuppelglieder zur Verbindung der einzelnen Reflektoren untereinander zur Bildung der Infrarot-Strahlungsanlage vorgesehen sind. Durch diese besondere Ausbildung der Reflektoren, also durch die schräggestellten Wände in Verbindung mit der Anordnung der Kuppelglieder, wird ein sehr großer Schwenkbereich der einzelnen Heizelemente untereinander erreicht, der eine Anpassung der Infrarot-Strahlungsanlage an praktisch beliebig geformte Bestrahlungsgüter erlaubt. Es versteht sich, daß die Scharnierteile auch zur Aufnahme von sich über mehrere Reflektoren erstreckende Tragelemente, wie Stäbe, Rohre oder dgl., eingerichtet sind, so daß bei der Montage größerer Anlagen besondere Tragkonstruktionen eingespart werden können. Aus Gründen einer erleichterten Lagerhaltung werden vorzugsweise einheitliche oder gleichartige Strahler und Reflektoren verwendet.This is achieved according to the invention in that the radiators are designed as ceramic radiators, that the reflectors are made of stainless steel sheet, serve as direct supports for the radiator and have inclined walls, on the longitudinal edges of which the coupling elements in the form of hinges made of bushings and articulated joints. or support bolts are provided. It is therefore here departed from the division into two parts between the reflector and the housing, which is known in the prior art, and the reflector is used as a direct support for the radiator. This considerably simplifies the individual heating elements. The reflectors have inclined walls, on the longitudinal edges of which the coupling elements are then provided for connecting the individual reflectors to one another to form the infrared radiation system. This special design of the reflectors, that is to say through the inclined walls in connection with the arrangement of the coupling elements, achieves a very large swiveling range of the individual heating elements with respect to one another, which allows the infrared radiation system to be adapted to virtually any desired radiation material. It goes without saying that the hinge parts are also designed to accommodate supporting elements, such as rods, pipes or the like, which extend over a plurality of reflectors, so that special supporting structures can be saved when larger systems are being installed. For reasons of easier storage, uniform or similar emitters and reflectors are preferably used.
Eine dem zu erzielenden Heizeffekt entsprechende Anzahl von Heizkörpern können nebeneinanderliegend in dem Reflektor untergebracht sein. Weiterhin können die Heizkörper stab- oder rechteckförmig geformt und paralell zueinanderliegend in dem gemeinsamen, sich über die mehreren Heizkörper erstreckenden Reflektor in wahlweiser Anordnung und Anzahl, dem gewünschten Heizeffekt entsprechend, angeordnet sein. Damit ergibt sich der Vorteil, daß sowohl die Heizleistung als auch die Anordnung, also insgesamt der Heizeffekt, den jeweils vorliegenden Bedingungen fast beliebig angepaßt werden kann.A number of radiators corresponding to the heating effect to be achieved can be accommodated side by side in the reflector. Furthermore, the radiators can have a rod-shaped or rectangular shape and can be arranged parallel to one another in the common reflector, which extends over the plurality of radiators, in an optional arrangement and number, corresponding to the desired heating effect. This has the advantage that both the heating power and the arrangement, that is to say the heating effect as a whole, can be adapted to the prevailing conditions almost as desired.
Die Heizkörper können in ihren Endbereichen liegende Auflagen aufweisen, die zur Befestigung in dem Reflektor dienen. Separate Befestigungsteile sind somit nicht mehr erforderlich.The radiators can have supports lying in their end regions, which are used for fastening in the reflector. Separate fasteners are no longer required.
Die Heizkörper können parallel zur Reflektorlängsachse verlaufend im Reflektor untergebracht sein.The radiators can be accommodated in the reflector running parallel to the longitudinal axis of the reflector.

In Fig. 1 und 2 ist ein Reflektor wiedergegeben, der vorteilhaft aus hochglänzendem. Edelstahl besteht. Der Reflektor ist so geformt, daß sich zu beiden Seiten einem entsprechend breiten Rückenteil 1 schräggestellte Wände 2 anschließen, wobei im Rückenteil 1 Bohrungsgruppen 3a, 3b oder 3c vorgesehen sind für den wahlweisen Einbau von noch später zu beschreibenden elektrischen Heizkörpern 4. Außerdem sind am Rand Durchbohrungen 5 vorgesehen für das Hindurchführen von an den Heizkörpern 4 vorgesehenen Stromzuleitungen 6 (Fig. 1).1 and 2, a reflector is shown, which is advantageously made of high-gloss. Stainless steel. The reflector is shaped in such a way that a correspondingly
Schließlich weist der Reflektor an den Längsrändern der Teile 2 Buchsen 7 auf, die zur Aufnahme von Gelenk- oder Tragbolzen 8 bestimmt sind. Die Buchsen 7 sind derart versetzt und in solchem Abstand zueinander angeordnet, daß zwischen sie ein weiterer Reflektor mit seinen Gelenkbuchsen eingesetzt werden kann und auf diese Weise eine scharnierartige Verbindung mehrerer Reflektoren miteinander entsteht.Finally, the reflector has 2
Selbstverständlich ist es auch möglich, in die Buchsen 7 Tragstäbe o. dgl. einzusetzen, die es gestatten, in einfachster Weise mehrere Reflektoren hintereinanderliegend zu einer Anlage aufzubauen.Of course, it is also possible to use support rods or the like in the
Wie bereits gesagt, lassen sich in einem eben beschriebenen Reflektor mehrere keramische Heizkörper 4 nebeneinander unterbringen, je nachdem, wie groß die zu erzielende Heizleistung sein soll. Es werden dann beispielsweise ein, zwei oder drei Heizkörper 4 nebeneinander oder an einem der Anschlüsse 3a, 3b oder 3c befestigt.As already mentioned, several
Mit der gezeigten Reflektorausbildung ist es ohne Schwierigkeiten möglich, beliebig viele Reflektoren neben- und hintereinander vorzusehen, die dann untereinander durch die Scharnier verbunden sind und sich dem jeweiligen Bedarf entsprechend bzw. dem Verlauf der Oberfläche des zu beheizenden Werkstückes W anpassen können, wie es die Fig. 9 bis 16 schematisch wiedergeben.With the reflector design shown, it is possible without difficulty to provide any number of reflectors side by side and one behind the other, which are then connected to one another by the hinge and can adapt to the particular need or to the shape of the surface of the workpiece W to be heated, as is the case Fig. 9 to 16 show schematically.
Von besonderem Vorteil ist die Ausführung der zur Verwendung gelangenden keramischen Heizkörper. Diese besitzen, wie es besonders die Fig. 5 bis 7 erkennen lassen, eine schlanke, längliche, rechteckige Form, wobei die in den Keramikkörper eingebetteten Heizleiter 10 den in Fig. 7 gestrichelt eingezeichneten Verlauf haben und in die an den Enden der Keramikkörper 4 vorgesehenen Stromzuleitungen 6 übergehen.The design of the ceramic radiators used is particularly advantageous. 5 to 7, they have a slender, elongated, rectangular shape, the
Andererseits sind die Heizkörper nicht, wie bisher üblich, in ihrer Mitte mit einem Befestigungsstutzen versehen, sondern sie besitzen im Endbereich aus Keramikmasse gebildete Auflager 9, durch die beispielsweise ein Befestigungsdraht 11 hindurchgeführt ist. Wegen der Länge der Keramikkörper sind auf ihrer Rückseite zwei solcher Auflager 9 vorgesehen. Bei der wahlweisen Montage der Heizkörper im Reflektor werden die Befestigungsdrähte 11 durch die Bohrungen 3a, 3b oder 3c hindurchgeführt und auf der Reflektorrückseite miteinander verdrillt. Die Stromzuleitungen 6 hingegen werden durch die Bohrungen 5 hindurchgeführt und auf der Reflektorrückseite mit Anschlußklemmen verbunden.On the other hand, the radiators are not provided with a fastening piece in the middle, as was customary hitherto, but instead they have supports 9 made of ceramic mass in the end region, through which a
