Description

Die vorliegende Erfindung betrifft eine Bestrahlungseinheit in Form eines plattenförmigen Bauelementes mit einem Trägerrahmen, der mehrere Bestrahlungslampen an Halterungen aufnimmt, wobei die Bestrahlungslampen von einer vorderen und einer hinteren Abdeckung abgedeckt sind und wobei die vordere, für Strahlung durchlässige Abdeckung abnehmbar gehalten ist.The present invention relates to an irradiation unit in the form of a plate-shaped component with a support frame which accommodates a plurality of irradiation lamps on brackets, the irradiation lamps being covered by a front and a rear cover and the front cover which is transparent to radiation being held detachably.

Solche Bestrahlungseinheiten sind allgemein bekannt, beispielsweise aus der Produktinformation der Heraeus Quarzschmelze INFRAROT "Mittelwellige Modul-Infrarotstrahler", Q-D1/140 D/E, D/E 3C 6.85/VN S&S. Diese Bestrahlungseinheiten können zum Trocknen und Erwärmen bei der Kleinteilefertigung im Labor und beim Verformen von Thermoplasten eingesetzt werden. Die Größe dieser Bestrahlungseinheiten beträgt etwa 250 x 500 mm. Mehrere solcher Bestrahlungseinheiten können zu einer Wand oder einer anderen großflächigen Bestrahlungseinheit, wie beispielsweise ein Bestrahlungstunnel oder ein Portal, zusammengesetzt werden, um große Teile oder Gegenstände zu bestrahlen. Das Gehäuse dieser Bestrahlungseinheiten besteht aus einem einseitig offenen Blechkasten mit einem Trägerrahmen als Verstärkung, von dessen offenen Seite aus die Strahler eingesetzt und befestig werden. Je nach Einsatzgebiet wird die Vorderseite dieser Bestrahlungseinheiten beispielsweise durch ein Schutzgitter abgedeckt. Es sind aber auch Bestrahlungseinheiten bekannt, bei denen die Abdeckung aus einer Glasscheibe besteht, die für die Strahlung (üblicherweise werden in solchen Bestrahlungseinheiten Infrarotstrahler eingesetzt) durchlässig sind. Nach längerem Einsatz ist festzustellen, daß sich auf den Abdeckungen Staub und andere Schmutzpartikel absetzen, die einerseits von Zeit zu Zeit auf das zu bestrahlende Objekt herabfallen oder andererseits die Strahlungsdurchlässigkeit einer eingesetzen Scheibe verringeren. Die Abdeckungen müssen daher wiederholt gereinigt oder ersetzt werden, wozu Leisten, mit denen sie an den Trägerrahmen befestigt sind, gelöst und wieder verschraubt werden müssen. Weiterhin wurde festgestellt, daß mit Klemmleisten befestigte Abdeckungen aus Quarzglas brechen, da beim Einsatz der Strahler durch den unterschiedlichen Längenausdehnungskoeffizienten Spannungen zwischen den Glasscheiben und dem Trägerrahmen bzw. den Abdeckungen entstehen.Such radiation units are generally known, for example from the product information of the Heraeus quartz melt INFRARED "medium-wave module infrared emitters", Q-D1 / 140 D / E, D / E 3C 6.85 / VN S&S. These radiation units can be used for drying and heating in small parts production in the laboratory and for molding thermoplastics. The size of these radiation units is approximately 250 x 500 mm. A plurality of such irradiation units can be put together to form a wall or another large-area irradiation unit, such as an irradiation tunnel or a portal, in order to irradiate large parts or objects. The housing of these radiation units consists of a sheet metal box open on one side with a support frame as reinforcement, from the open side of which the radiators are inserted and fastened. Depending on the area of application, the front of these radiation units is covered, for example, by a protective grille. However, radiation units are also known in which the cover consists of a glass pane which is used for the radiation (usually used in such radiation units Infrared emitters used) are permeable. After prolonged use, it can be seen that dust and other dirt particles settle on the covers, which on the one hand fall from time to time onto the object to be irradiated or on the other hand reduce the radiation permeability of an inserted pane. The covers must therefore be repeatedly cleaned or replaced, for which strips with which they are attached to the support frame, must be loosened and screwed again. It was also found that quartz glass covers fastened with terminal strips break, since when the radiators are used, stresses arise between the glass panes and the support frame or the covers due to the different linear expansion coefficients.

Der vorliegenden Erfindung liegt nun die Aufgabe zugrunde, eine Bestrahlungseinheit der eingangs beschriebenen Art derart auszugestalten, daß eine einfache und schnelle Montage sowie ein schneller Wechsel der vorderen als auch einer hinteren Abdeckung u.a. zum Wechsel der innen montierten Strahler möglich wird und weiterhin ein Längenausgleich zwischen den Abdeckungen und dem Trägerrahmen gegeben ist.The present invention is based on the object of designing an irradiation unit of the type described at the outset in such a way that simple and quick assembly and rapid change of the front and rear cover, among other things. to change the internally mounted spotlights is possible and there is still a length compensation between the covers and the support frame.

Gelöst wird diese Aufgabe bei einer solchen Bestrahlungseinheit dadurch, daß die vordere und/oder die hintere Abdeckung mit der nach außen gerichteten Seite jeweils gegen mit dem Trägerrahmen verbundene Anschläge anliegt und jeweils der Innenseite Federelemente zugeordnet sind, die an der Innenseite anliegend die jeweilige Abdeckung an die Anschläge andrücken. Die Abdeckungen werden durch die Federelemente gegen die an der Außenseite anliegenden Anschläge gedrückt derart, daß sie einerseits sicher gehalten werden, aber andererseits noch eine ausreichende Verschiebbarkeit infolge von Längenausdehnungen gegeben ist. Zur Herausnahme der Abdeckung wird diese gegen die Kraft der Feder nach innen gedrückt und uber die Anschläge gehoben. Auf diese Weise können die vorderen Abdeckungen zu Reinigungszwecken leicht entfernt werden. Abdeckungen an der Rückseite der Bestrahlungseinheit, die über solche Federelemente gehalten werden, können notwendig sein, um die Strahler zu wechseln oder eine gute Zugänglichkeit der elektrischen Anschlüsse der Strahler zu gewährleisten. Die Anschläge, gegen die die Abdeckungen mit ihrer Außenseite anliegen, können durch Rahmen oder Rahmenteile gebildet werden, die mit dem Trägerrahmen verschraubt oder verschweißt werden. Es können hierbei Abdeckleisten ausreichend sein, die zwei gegenüberliegenden Seitenkanten der Abdeckung, bevorzugt den längeren Seiten der Abdeckung, zugeordnet sind. Um die Abdeckungen gleichmäßig zu halten, sind Federelemente jeweils im Bereich von zwei gegenüberliegenden Seitenkanten der jeweiligen Abdeckung ausreichend. Die Federelemente sind bevorzugt Spiralfedern, die mit ihrer Achse in Richtung der Flächennormalen der Abdeckungen ausgerichtet sind und, je nach Länge, an einem Bolzen oder Stift oder einer anderen Führung geführt werden. Um nicht nur punktförmige Auflagen im Bereich der Federn zu erhalten, können die Federelemente an Schienen oder Leisten angreifen, die an der Innenseite der Abdeckungen anliegen und sich jeweils entlang einer Seitenkante der Abdeckung erstrecken. Je nach Größe der Abdeckungen reicht eine Leiste mit einer an der Mitte angreifenden Feder oder eine Leiste mit jeweils einer Feder an deren Enden aus. In einer weiteren bevorzugten Ausführungsform, bei der die Abdeckungen rechteckige oder quadratische Platten sind, wird deren Größe derart gewählt, daß sie hinter den Anschlägen in Richtung einer Seitenkante um eine der Überdeckung der Seitenkante durch den ihr zugeordneten Anschlag entsprechenden Länge verschiebbar gehalten ist. In dieser Anordnung werden die Abdeckungen zum Wechsel in die eine Richtung hinter den Anschlägen verschoben, bis die andere Seitenkante von den ihr zugeordneten Anschlägen freigegeben ist. Um aber eine solche Abdeckung in eingebautem Zustand unverrückbar zu festzulegen, kann eine Leiste mit einem die Kante der Abdeckung abstützenden Vorsprung von Vorteil sein, so daß die Abdeckungen in ihrer Lage durch die Leisten fixiert sind. Zum Lösen der Abdeckungen wird die Leiste zum Innenraum hin gegen die Federn verschoben, bis der abstützende Vorsprung die Seitenkante freigibt. Als vorteilhaft hat sich eine Bestrahlungseinheit erwiesen, die eine vordere Abdeckung aus für Infrarot-Strahlung durchlässigen Glasscheiben aufweist und die mit Infrarotstrahlern bestückt ist.This object is achieved in such an irradiation unit in that the front and / or the rear cover with the outwardly facing side is in each case against stops connected to the support frame and in each case spring elements are assigned to the inside, which bear against the respective cover on the inside press the stops. The covers are pressed by the spring elements against the abutments on the outside in such a way that they are held securely on the one hand, but on the other hand there is still sufficient displacement as a result of length extensions. To remove the cover, press it inwards against the force of the spring and lift it over the stops. In this way, the front covers can be easily removed for cleaning purposes. Covers on the back of the radiation unit, which are held over such spring elements, may be necessary in order to change the radiator or good access to the electrical connections to ensure the spotlight. The stops against which the covers abut with their outside can be formed by frames or frame parts which are screwed or welded to the support frame. In this case, cover strips can be sufficient, which are assigned to two opposite side edges of the cover, preferably the longer sides of the cover. To keep the covers uniform, spring elements in the area of two opposite side edges of the respective cover are sufficient. The spring elements are preferably spiral springs which are aligned with their axes in the direction of the surface normal of the covers and, depending on the length, are guided on a bolt or pin or some other guide. In order not only to obtain punctiform supports in the area of the springs, the spring elements can engage rails or strips which rest against the inside of the covers and each extend along a side edge of the cover. Depending on the size of the covers, a strip with a spring engaging in the middle or a strip with a spring at each end is sufficient. In a further preferred embodiment, in which the covers are rectangular or square plates, their size is selected such that it is held behind the stops in the direction of a side edge by a length corresponding to the overlap of the side edge by the stop corresponding to it. In this arrangement, the covers are shifted in one direction behind the stops for changing until the other side edge is released from the stops assigned to them. However, in order to immovably fix such a cover in the installed state, a strip with a projection supporting the edge of the cover can be advantageous, so that the covers are fixed in their position by the strips. To release the covers, the bar is moved towards the interior against the springs until the supporting projection releases the side edge. An irradiation unit has proven to be advantageous which has a front cover made of glass panes which are permeable to infrared radiation and which is equipped with infrared radiators.

Weitere Einzelheiten der Erfindung ergeben sich aus der nachfolgenden Beschreibung eines Ausführungsbeispieles anhand der Zeichnung. In der Zeichnung zeigt

  • Figur 1 einen Längsschnitt durch eine Bestrahlungseinheit mit einer vorderen und einer hinteren Abdeckung,
  • Figur 2 eine vergrößerte Darstellung der Anordnung nach Figur 1 im Bereich eines Federelementes und
  • Figur 3 einen Schnitt entlang der Schnittlinie III-III in Figur 2.
Further details of the invention result from the following description of an embodiment with reference to the drawing. In the drawing shows
  • FIG. 1 shows a longitudinal section through an irradiation unit with a front and a rear cover,
  • Figure 2 is an enlarged view of the arrangement of Figure 1 in the region of a spring element and
  • 3 shows a section along the section line III-III in FIG.

Die Bestrahlungseinheit nach der Figur 1, von der nur die linke Hälfte zu sehen ist, weist einen Trägerrahmen 1 in Form eines Hohlprofiles auf, mit einer vorderen Abdeckung 2 und einer hinteren Abdeckung 3. Die beiden Abdeckungen 2, 3 liegen mit ihrer Oberseite gegen Anschläge 4 an, die durch verschraubte Schienen an zwei gegenüberliegenden Seiten des rechteckigen oder quadratischen Trägerrahmens 1 gebildet werden. An der Innenseite des Trägerrahmens 1 sind beidseitig Hilfsrahmen 5 befestigt, die an einer Halterung 6 einen Bolzen 7 mit einem darauf aufgeschobenen Federelement 8, wie auch die Figuren 2 und 3 zeigen, tragen. Der Bolzen 7 ist in Richtung des Pfeiles 9, d.h. senkrecht zu der jeweiligen Abdeckung 2, 3, verschiebbar, wobei das Federelement 8 eine Leiste 10 gegen die Unterseite der Abdeckungen drückt. Jeder Leiste 10 sind mindestens zwei Federelemente 8 im Bereich der Enden der Leisten 10, wie die Figur 3 zeigt, zugeordnet.The radiation unit according to FIG. 1, of which only the left half can be seen, has a support frame 1 in the form of a hollow profile, with a front cover 2 and a rear cover 3. The top of the two covers 2, 3 lie against stops 4, which are formed by screwed rails on two opposite sides of the rectangular or square support frame 1. On the inside of the support frame 1, auxiliary frames 5 are fastened on both sides, which support a bolt 7 on a holder 6 with a spring element 8 pushed thereon, as also shown in FIGS. 2 and 3. The bolt 7 is in the direction of arrow 9, i.e. perpendicular to the respective cover 2, 3, displaceable, the spring element 8 pressing a bar 10 against the underside of the covers. Each strip 10 is assigned at least two spring elements 8 in the region of the ends of the strips 10, as shown in FIG. 3.

Um die Bestrahlungseinheit, die in ihrer Größe von dem Trägerrahmen 1 begrenzt wird, in Bestrahlungseinheiten mit Abdeckungen 2, 3 geringer Größe zu unterteilen, sind im mittleren Bereich der Bestrahlungseinheit weitere Hilfsrahmen 5 angeordnet, die zur Aufnahme der Federelemente 8 für die jeweils angrenzende Abdeckungen 2, 3 dienen und an denen die Anschläg 4 befestigt sind. An dem Trägerrahmen 1 sowie an Stützen 11 sind Profilschienen 12 horizontal, d.h. parallel zu den Abdeckungen 2, 3, verlaufend befestigt, die Klemmschuhe 13 mit Halterungen 14 für nicht näher gezeigte Infrarotstrahler aufnehmen. Sowohl die vordere Abdeckung 2 als auch die hintere Abdeckung 3 können in Richtung der Pfeile 14 verschoben werden, so daß sie aus der Überlappung mit den Anschlägen 4 (hierbei handelt es sich um durchgehende, flache Schienen) gebracht werden, um sie von der Bestrahlungseinheit zu entfernen. Auf diese Weise sind sowohl die Infrarotstrahler über die vordere Abdeckung 2 als auch die elektrischen Anschlüsse für die Strahler an den Klemmschuhen 13 über die hintere Abdeckung 3 gut zugänglich. Da die Abdeckungen 2, 3 in Richtung der Pfeile 14 verschiebbar sind, d.h. ihre Länge kürzer ist als die lichte Weite zwischen dem Hilfsrahmen 5, kann eine Leiste 10 mit einem Hilfsprofil 15 eingesetzt werden, das an der Stirnseite der Abdeckung 3, wie dies die Figur 2 zeigt, anliegt, und die Abdeckung in ihrer Lage fixiert. Die Abdeckung 3 wird, nachdem die Leiste 10 nach hinten in Richtung des Pfeiles 9 verschoben ist, freigegeben. Durch die Federelmente ist eine einfache Austauschbarkeit der Abdeckungen 2, 3 gegeben; die Abdeckungen werden gleichzeitig durch die Leisten 10 mit den daran angreifenden Federelementen 8 in ihrer Lage sicher gehalten. Des weiteren können mit diesen Federelementen 8 unterschiedliche Längenausdehnungen zwischen den Rahmen 1, 5 und den Abdeckungen 2, 3, beispielsweise aus Quarzglas, ausgeglichen werden.In order to divide the irradiation unit, which is limited in size by the carrier frame 1, into irradiation units with covers 2, 3 of small size, further auxiliary frames 5 are arranged in the central region of the irradiation unit, which are used to hold the spring elements 8 for the respective adjacent covers 2 , 3 serve and to which the stops 4 are attached. Profile rails 12 are on the support frame 1 and on supports 11 mounted horizontally, ie parallel to the covers 2, 3, the clamping shoes 13 with brackets 14 for infrared radiators, not shown. Both the front cover 2 and the rear cover 3 can be moved in the direction of the arrows 14 so that they are brought out of the overlap with the stops 4 (these are continuous, flat rails) in order to be removed from the radiation unit remove. In this way, both the infrared emitters are easily accessible via the front cover 2 and the electrical connections for the emitters on the clamping shoes 13 via the rear cover 3. Since the covers 2, 3 are displaceable in the direction of the arrows 14, ie their length is shorter than the clear width between the auxiliary frame 5, a strip 10 with an auxiliary profile 15 can be used, which is on the front side of the cover 3, as is the case with the Figure 2 shows, is applied, and the cover fixed in position. The cover 3 is released after the bar 10 is moved backwards in the direction of the arrow 9. The spring elements make it easy to replace the covers 2, 3; the covers are simultaneously held securely in position by the strips 10 with the spring elements 8 acting on them. Furthermore, with these spring elements 8 different lengths between the frames 1, 5 and the covers 2, 3, for example made of quartz glass, can be compensated.
