Description

Die Erfindung betrifft einen Strahlungstrockner im Kammerbauweise, der typischerweise mit sogenannten NIR-Strahlerelementen (die hauptsächlich im Bereich des nahen Infrarot Strahlung mit hoher Leistungsdichte emittieren) und/oder Hochleistungs-UV-Strahlern bestückt ist. Sie betrifft weiterhin eine mit mehreren Strahlungstrocknern dieser Art aufgebaute Trocknungsanlage, wie sie insbesondere zur Trocknung von Beschichtungen auf einem schnell hindurchlaufenden quasi-endlosen Gut eingesetzt wird.The invention relates to a radiation dryer in chamber construction, which is typically equipped with so-called NIR radiator elements (which emit mainly in the range of near infrared radiation with high power density) and / or high-power UV lamps. It further relates to a dryer constructed with a plurality of radiation dryers of this type, as used in particular for drying coatings on a fast-passing quasi-endless good.

Strahlungstrockner und Trocknungsanlagen der hier in Rede stehenden Art haben in den letzten Jahren zunehmend Einsatz in großtechnischen Coilcoating-Anlagen zur Lackbeschichtung und/oder Galvanisierung von wickelfähigem Blech Einsatz gefunden, werden für die Trocknung bzw. Vernetzung von Lacken oder lackartigen Beschichtungen auf anderen Trägern, zur Trocknung von Papier und Pappe bzw. Produkten hieraus sowie von Druckerzeugnissen, zur Auflaminierung von Kunststofffolien auf verschiedenartige Träger und in weiteren Applikationen eingesetzt oder sind dort jedenfalls grundsätzlich einsetzbar. Als wichtiges Anwendungsfeld von konstruktiv sehr ähnlichen Anlagen mit NIR-Strahlerelementen haben sich auch Streckblasanlagen zur Herstellung von geblasenen Kunststoffflaschen erwiesen, bei denen die in Rede stehenden Geräte keine Trocknung, sondern eine Durchwärmung der Flaschen-Preforms vor dem Blasschritt bewirken. Die nachstehenden Ausführungen zur Erfindung gelten auch für Bestrahlungsvorrichtungen und Anlagen dieser Art.Radiation dryer and drying equipment of the type in question have been increasingly used in recent years in large-scale coil coating systems for paint coating and / or galvanization of windable sheet metal insert are used for the drying or crosslinking of paints or coatings on other substrates, for Drying of paper and cardboard or products thereof and of printed products, used for laminating of plastic films on various types of carriers and in other applications or are there in any case fundamentally applicable. As an important field of application of structurally very similar systems with NIR radiator elements also stretch blow molding for the production of blown plastic bottles have proven in which the devices in question cause no drying, but a warming of the bottle preforms before the blowing step. The following statements on the invention also apply to irradiation devices and systems of this type.

Eine jüngere Entwicklung der Anmelderin, die in der DE 10 2006 004 574.1 beschrieben wird, ist der sinnvollen Konstruktion eines Strahlungstrockners für den Coilcoating-Kleinserieneinsatz gewidmet.A recent development of the applicant, which in the DE 10 2006 004 574.1 is dedicated to the useful construction of a radiation dryer for the coil coating small series use.

Die stetige Verbesserung der Konstruktion und Funktionsweise von Strahlungstrocknern bzw. vergleichbaren Bestrahlungseinrichtungen der in Rede stehenden Art ist in den letzten Jahren Gegenstand umfangreicher Entwicklungen gewesen, in deren Ergebnis u.a. eine ganze Reihe von Schutzrechtsveröffentlichungen der Anmelderin entstand. Mit der zunehmenden Großserienreife der Technik und ihrem Einsatz in Produktionsanlagen mit höchster Produktivität treten Aspekte wie eine lange unterbrechungsfreie Einsatzdauer und eine zeitliche und kostenseitige Minimierung von unumgänglichen Wartungsvorgängen und den damit verbundenen Produktionsunterbrechungen ebenso in den Vordergrund wie das Ziel, auch Strahlungstrockner für Großanlagen möglichst weitgehend vorzufertigen und die bauseitigen Arbeiten auf ein Minimum zu beschränken.The steady improvement in the design and operation of radiation dryers or comparable irradiation facilities of the type in question has been the subject of extensive developments in recent years, the result u.a. a whole series of proprietary rights publications of the applicant emerged. With the increasing mass production maturity of the technology and its use in production plants with maximum productivity aspects such as a long uninterrupted service life and a time and cost minimization of inevitable maintenance operations and the associated production interruptions as well as the goal as well as radiant dryer for large systems as far as possible prefabricate and to keep the on-site work to a minimum.

Aus der EP 0 416 944 A ist ein Strahlungstrockner als Bestandteil einer Trocknungsanlage zum Trocknen einer Beschichtung auf einem schnell durchlaufenden Träger bekannt, mit einem Bestrahlungsgut-Transportkanal zum Hindurchfördern des quasi-endlosen Trägers als Bestrahlungsgut, einem in Gebrauchslage an einer Längsseite des Bestrahlungsgut-Transportkanals angeordneten und zu Wartungszwecken gegenüber der Gebrauchslage verschwenkbaren ersten Strahlerblock, der eine Vielzahl von Strahlerelementen vom NIR- oder UV-Lampen-Typ umfasst, und einem in Gebrauchslage an einer zweiten Längsseite des Bestrahlungsgut-Transportkanals angeordneten und zur Wartung gegenüber der Gebrauchslage verschwenkbaren zweiten Strahlerblock.From the EP 0 416 944 A a radiation dryer is known as part of a drying system for drying a coating on a fast-moving carrier, with an irradiation transport channel for conveying the quasi-endless carrier as irradiation, arranged in use position on a longitudinal side of the irradiation material transport channel and for maintenance against the use position pivotable first radiator block comprising a plurality of radiator elements of the NIR or UV lamp type, and arranged in the use position on a second longitudinal side of the irradiation material transport channel and pivotable for maintenance relative to the use position second radiator block.

Aus der DE 37 44 799 A1 ist eine Prozessanlage für die Wärmebehandlung von bahnförmigen Produkten bekannt, bei der ein strahlungsdurchlässiges Schutzscheibenelement fest am Strahlerblock einer Trockner-Komponente montiert ist.From the DE 37 44 799 A1 is a process plant for the heat treatment of web-shaped products is known in which a radiolucent shield member is fixedly mounted on the radiator block of a dryer component.

Der Erfindung liegt die Aufgabe der Bereitstellung eines verbesserten Strahlungstrockners zugrunde, der sich besonders durch verkürzte Wartungs- und Produktionsunterbrechungszeiten im Einsatz bei einem Bestrahlungsgut auszeichnet, welches dazu neigt, die Strahler bzw. Reflektoren zu verschmutzen.The invention is based on the object of providing an improved radiation dryer, which is particularly characterized by shortened maintenance and production interruption times characterized in use in an irradiation, which tends to pollute the radiators or reflectors.

Diese Aufgabe wird durch einen Strahlungstrockner mit den Merkmalen des Anspruchs 1 gelöst. Zweckmäßige Fortbildungen des Erfindungsgedankens sind Gegenstand der abhängigen Ansprüche.This object is achieved by a radiation dryer with the features of claim 1. Advantageous developments of the inventive concept are the subject of the dependent claims.

Die Erfindung geht von der Überlegung aus, dass bei der Bestrahlung (speziell Trocknung) bestimmter Bestrahlungsgüter wegen der relativ großen Verschmutzungsneigung der Strahler und Reflektoren in relativ kurzen Intervallen eine Reinigung bzw. ein Austausch erforderlich ist und die Strahler und Reflektoren hierzu möglichst leicht und schnell zugänglich gemacht werden sollten.The invention is based on the consideration that in the irradiation (especially drying) of certain irradiation due to the relatively high tendency to fouling of the emitters and reflectors in relatively short intervals cleaning or replacement is required and the spotlights and reflectors for this purpose as easily and quickly accessible should be made.

Die Erfindung sieht daher vor, dass ein bei einem Strahlungstrockner mit einem Bestrahlungsgut-Transportkanal an einer von dessen Längsseiten vorgesehener erster Strahlerblock zu Wartungszwecken von der Längsseite abrückbar oder gegenüber der Gebrauchslage verschwenkbar ist, und dass ebenso ein an der zweiten Längsseite angeordneter zweiter Strahlerblock oder Gegenreflektorblock angebracht und bewegbar ist. Nach dem Abrücken oder - bevorzugt - Aufklappen des jeweiligen Strahler- bzw. Reflektorblockes ist dessen Inneres frei zugänglich, und verschmutzte Strahler- bzw. Reflektorelemente oder -abschnitte sind sofort als solche erkennbar und können leicht und schnell gereinigt oder ausgetauscht werden, und danach kann der jeweilige Block ebenso zügig wieder in seine Gebrauchslage überführt werden.The invention therefore provides that a first in a radiation dryer with a Strahlungsgut transport channel on one of its longitudinal sides provided Radiator block for maintenance purposes from the longitudinal side abrückbar or against the use position is pivotable, and that also mounted on the second longitudinal side second radiator block or counter reflector block is mounted and movable. After moving away or - preferably - unfolding the respective radiator or reflector block whose interior is freely accessible, and dirty radiator or reflector elements or sections are immediately recognizable as such and can be easily and quickly cleaned or replaced, and then the respective block quickly be transferred back to its position of use as well.

In bestimmten Ausführungen der Strahlungstrockner ist zwischen dem Bestrahlungsgut und den Strahlerelementen und mitunter auch zwischen Bestrahlungsgut und Gegenreflektoren eine strahlungsdurchlässige Schutzscheibe vorgesehen, um aus dem Bestrahlungsgut austretendes Material abzufangen und somit werkstückbedingte Verschmutzungen der Strahler bzw. Reflektoren weitgehend zu verhindern. Auch in solchen Konfigurationen ist die Erfindung aber sinnvoll einsetzbar, denn die Strahler und Reflektoren unterliegen auch umgebungsbedingten Verschmutzungen, weil mit Blick auf die erforderliche hohe Kühlleistung einer Filterung der Kühlluft Grenzen gesetzt sind.In certain embodiments of the radiation dryer, a radiation-permeable protective pane is provided between the irradiation material and the radiator elements and sometimes also between the irradiation material and counter-reflectors in order to intercept material emerging from the irradiation material and thus largely prevent workpiece-related contamination of the radiators or reflectors. Even in such configurations, however, the invention is useful, because the spotlights and reflectors are also subject to pollution caused by the environment, because in view of the required high cooling capacity filtering the cooling air limits are set.

In einer solchen Strahlungstrockner-Ausführung gemäß einem Aspekt der Erfindung ist vorgesehen, dass die entsprechenden Schutzscheiben in verfahr- oder schwenkbaren Schutzscheibenelementen gehaltert sind. Deren Verfahr- oder Schwenkbarkeit macht die jeweiligen Scheiben für eine Reinigung oder einen Austausch leicht und schnell zugänglich. Grundsätzlich ist eine ausfahrbare Anordnung der Schutzscheibe(n) auch unabhängig von einer Abrückbarkeit oder Verschwenkbarkeit des zugeordneten Strahler- oder Reflektorblockes möglich und insbesondere dann sinnvoll, wenn werkstückbedingte Verschmutzungen unter bestimmten Einsatzbedingungen weit gravierender als umgebungsbedingte Verschmutzungen sind und daher regelmäßige Reinigungsarbeiten praktisch nur an der Schutzscheibe oder den Schutzscheiben ausgeführt werden müssen. Sind hingegen sowohl an den Strahler- bzw. Reflektorblöcken als auch an den Schutzscheiben häufig Reinigungsoder Austauscharbeiten auszuführen, ist eine Ausführung sinnvoll, bei der sowohl der erste als auch der zweite Strahlerblock bzw. der Gegenreflektorblock und mindestens ein zugeordnetes Schutzscheibenelement um eine an einer Längskante des Bestrahlungsgut-Transportkanals angeordnete Drehachse verschwenkbar sind.In such a radiation dryer embodiment according to one aspect of the invention, it is provided that the corresponding protective disks are held in movable or pivotable protective disk elements. Their traversing or pivoting makes the respective discs easily and quickly accessible for cleaning or replacement. Basically, an extendable arrangement of the protective disc (s) is also possible regardless of a Abrückbarkeit or pivoting the associated radiator or reflector block and especially useful if workpiece-related contamination under certain conditions of use are far more serious than environmental pollution and therefore regular cleaning virtually only on the protective pane or the protective windows must be performed. On the other hand, if cleaning or replacement work is to be carried out frequently both on the radiator or reflector blocks and also on the protective disks, an embodiment is useful in which both the first as well as the second radiator block or the counter reflector block and at least one associated protective disk element are pivotable about an axis of rotation disposed on a longitudinal edge of the irradiation material transport channel.

Grundsätzlich kann das Bewegen des Strahler- bzw. Reflektorblockes und optional der Schutzscheibe(n), jedenfalls bei kleineren Trocknern, manuell erfolgen. Bevorzugt sind jedoch Ausführungen, bei denen zum Abrücken oder Schwenken des Strahlerblocks und/oder Reflektorblocks ein elektromotorischer, hydraulischer, pneumatischer oder elektromagnetischer Antrieb vorgesehen ist. Ein solcher Antrieb erleichtert die Arbeit des Wartungspersonals und ist, mit Blick auf die hohen Betriebstemperaturen und die erhebliche Restwärme nach Abschalten des Trockners, auch unter Arbeitsschutzaspekten vorteilhaft.In principle, the moving of the radiator or reflector block and optionally the protective screen (s), at least for smaller dryers, can be done manually. However, embodiments are preferred in which an electromotive, hydraulic, pneumatic or electromagnetic drive is provided for the removal or pivoting of the radiator block and / or reflector block. Such a drive facilitates the work of the maintenance personnel and, in view of the high operating temperatures and the considerable residual heat after switching off the dryer, also advantageous under occupational safety aspects.

Während grundsätzlich nach dem Öffnen eine manuelle Reinigung bzw. Auswechslung von Strahler- oder Reflektorelementen möglich ist, ist in einer "High-end"-Ausführung des Strahlungstrockners jedem Strahler bzw. Reflektorblock eine Reinigungseinrichtung mit eigenem Antrieb (etwa in Art rotierender Bürsten) vorgesehen, die die Strahlerelemente bzw. Reflektoren mechanisch und ggf. unter gesteuertem Austrag von Reinigungsflüssigkeit aus entsprechenden Düsen oder Dosiereinrichtungen reinigt. Erhöhte Herstellungskosten eines derartigen Trockners werden im Dauereinsatz leicht durch eine weitere Verkürzung der Wartungszeit infolge der Möglichkeit einer großflächigen Reinigung vieler Strahlerelemente bzw. Reflektorabschnitte zur gleichen Zeit (und vor vollständiger Abkühlung) ausgeglichen.While in principle a manual cleaning or replacement of radiator or reflector elements is possible after opening, each radiator or reflector block is provided with a cleaning device with its own drive (for example, in the manner of rotating brushes) in a "high-end" version of the radiation dryer, which cleans the radiator elements or reflectors mechanically and optionally under controlled discharge of cleaning fluid from corresponding nozzles or metering devices. Increased production costs of such a dryer are easily compensated in continuous use by a further reduction in maintenance time due to the possibility of large-scale cleaning of many radiator elements or reflector sections at the same time (and before complete cooling).

Desweiteren kann sich eine High-end-Ausführung dadurch auszeichnen, dass jedem Strahlerblock eine Lampentest- und -wechselvorrichtung zur Erfassung der Funktionsfähigkeit und optional eines Verschmutzungsgrades und zum robotergestützten Austausch nicht funktionsfähiger oder übermäßig verschmutzter Strahlerelemente im Ansprechen auf das Erfassungsergebnis zugeordnet ist. Auch diese letztgenannte Ausführung kann im Einsatz erhebliche Zeit- und Kostenvorteile erbringen, weil durch Arbeitsschutzerfordernisse bedingte Wartezeiten vor einem Strahleraustausch bei maschineller Auswechslung der Strahler erheblich verkürzt werden können.Furthermore, a high-end design can be characterized in that each lamp block is assigned a lamp test and change device for detecting the operability and optionally a degree of contamination and the robot-assisted replacement of non-functional or excessively contaminated lamp elements in response to the detection result. Also, this latter design can provide considerable time and cost advantages in use, because due to occupational safety requirements related waiting times can be significantly reduced before a replacement lamp with mechanical replacement of the radiator.

Gemäß einem relativ unabhängigen Aspekt der Erfindung ist für den Strahlungstrockner eine Einhäusung, insbesondere aus Metallprofilen, vorgesehen, welche die Außenabmessungen eines Standardcontainers aufweist und Leistungssteuereinheiten zur Stromversorgung der Strahler und wahlweise des oder jedes Antriebes aufnimmt. Ein derartiges Rahmen-Gehäuse ermöglicht eine rationelle Vormontage des Strahlungstrockners im Herstellerbetrieb und einen ebenso rationellen Transport zum Einsatzort und Aufbau an diesem, unter weitgehendem Fortfall von aufwendigen Verpackungs- und Auspackschritten und bauseits zu erbringenden Komplettierungs- und Montageleistungen. Hierdurch können insgesamt die Gestehungskosten erheblich gesenkt werden.According to a relatively independent aspect of the invention, the radiation dryer is provided with a housing, in particular of metal profiles, which has the outer dimensions of a standard container and accommodates power control units for powering the radiators and optionally the or each drive. Such a frame housing allows a rational pre-assembly of the radiation dryer in the factory and an equally efficient transport to the job site and construction of this, with substantial elimination of costly packaging and Auspackschritten and on-site completion and assembly services. As a result, the total cost of ownership can be significantly reduced.

In einer Fortbildung ist vorgesehen, dass die Einhäusung aus Metallprofilen zusätzlich Lüfter und Luftfilterelemente zur Gebläse- oder Ansaugluftkühlung der Strahler und/oder des Bestrahlungsgutes aufnimmt. Hierbei ist insbesondere vorgesehen, dass die Einhäusung Schaltschränke zur Energieversorgung der Strahler in einer derartigen Anordnung aufnimmt und dass zur Kühlung der Strahler und/oder Gegenreflektoren angesaugte Umgebungsluft die Schaltschränke durchströmt und hierbei die darin angeordneten elektrischen Komponenten kühlt. Ein Container-Modul dieser Art umfasst somit in einer herstellungs- wie betriebsseitig hocheffektiven Anordnung alle wesentlichen Komponenten einer Bestrahlungs- bzw. Trocknungsvorrichtung und bietet Zeit- und Kostenvorteile in der Gestehung ebenso wie im laufenden Betrieb.In a further development, it is provided that the housing of metal profiles additionally accommodates fans and air filter elements for fan or intake air cooling of the radiators and / or of the irradiation material. In this case, provision is made in particular for the enclosure to receive control cabinets for supplying energy to the radiators in such an arrangement, and for the ambient air sucked in to cool the radiators and / or counter-reflectors to flow through the control cabinets, thereby cooling the electrical components arranged therein. A container module of this type thus comprises in a manufacturing and operating highly effective arrangement all the essential components of an irradiation or drying device and offers time and cost advantages in the supply as well as during operation.

Eine größere Trocknungsanlage lässt sich derart aufbauen, dass sie eine Mehrzahl von Strahlungstrocknern nach einem der vorangehenden Ansprüche mit zueinander vertikal ausgerichteten Bestrahlungsgut-Transportkanälen aufweist. Ein besonders zweckmäßiger modularer Aufbau ergibt sich, wenn jeder der Mehrzahl Strahlungstrockner in einer Einhäusung untergebracht ist und die Außenabmessungen der Einhäusungen identisch sind.A larger drying plant can be constructed such that it has a plurality of radiation dryers according to one of the preceding claims with mutually vertically aligned irradiation material transport channels. A particularly useful modular design results when each of the plurality of radiation dryers is housed in a housing and the outer dimensions of the housings are identical.

Fig. 2 zeigt als weitere Ausführung der Erfindung einen ähnlich aufgebauten Strahlungstrockner 1', bei dem ebenfalls auf beiden Längsseiten des Bestrahlungsgut-Transportkanals 3 je ein Schutzscheibenelement 7.1' bzw. 7.2' und ein Strahlerblock 9.1' bzw. 9.2' angeordnet sind. Bei dieser Ausführung sind die Schutzscheibenelemente und Strahlerblöcke jedoch nicht gegenüber dem Bestrahlungsgut-Transportkanal verschwenkbar, um den Trockner zu öffnen, sondern auf einer Schienenführung 14a, 14b parallel zu den Transportkanal-Längsseiten verschiebbar, wie durch die Pfeile in der Figur angedeutet. Auch hier kann eine (nicht dargestellte) motorische, hydraulische oder andere bekannte Antriebseinrichtung vorgesehen sein, die etwa über einen Zahnriemen oder eine Kette das Abrücken der Schutzscheibenelemente und Strahlerblöcke vom Transportkanal bewirkt. Fig. 2 shows as a further embodiment of the invention, a similarly constructed radiation dryer 1 ', in which also on each of the two longitudinal sides of the irradiation material transport channel 3 a protective screen element 7.1' or 7.2 'and a radiator block 9.1' or 9.2 'are arranged. In this embodiment, however, the protective screen elements and radiator blocks are not pivotable relative to the irradiation material transport channel to open the dryer, but on a rail guide 14a, 14b parallel to the transport channel longitudinal sides displaced, as indicated by the arrows in the figure. Again, a (not shown) motor, hydraulic or other known drive means may be provided, which causes about a toothed belt or a chain, the removal of the protective disk elements and radiator blocks from the transport channel.

Mit einer in der Figur nicht dargestellten Krantraverse kann über dem Strahlungstrockner 1' mit relativ geringem konstruktiven Aufwand eine Reinigungseinrichtung gehaltert sein, die etwa (in von Autowaschanlagen bekannter Art) Sprühdüsen und verfahrbare Bürstenwalzen zur Reinigung der Schutzscheiben und Strahlerblock-Vorderseiten umfasst. In ähnlicher Weise kann auch eine Hochdruckdampf-Reinigungseinheit o.ä. zur automatisierten Reinigung der von Verschmutzungen betroffenen Oberflächen dem Strahlungstrockner zugeordnet sein.With a Krantraverse, not shown in the figure, a cleaning device can be mounted on the radiation dryer 1 'with relatively little design effort, which includes about (in car washes known type) spray nozzles and movable brush rollers for cleaning the protective screens and radiator front surfaces. Similarly, a high-pressure steam cleaning unit or the like can also be used. be assigned to the radiation dryer for automated cleaning of contaminated surfaces.

Fig. 3 illustriert schematisch eine vorgefertigte Montagekonfiguration 15 eines Trockners 1 der in Fig. 1 gezeigten Art, eingefügt in einen Stahlprofilrahmen 17. Dieser Profilrahmen bildet eine Einhäusung des Strahlungstrockners 1, in der dieser transportiert und am Einsatzort aufgestellt werden kann. Innerhalb des Rahmens 17 sind neben dem eigentlichen Trockner Gebläseeinheiten 19 mit eingangsseitig zugeordneten Luftfiltereinheiten 21 sowie - in Strömungsrichtung abwärts der großflächigen Luftfiltereinheiten positioniert - Schaltschränken 23 für die Leistungssteuerung der Strahlerelemente des Strahlungstrockners 1 untergebracht. Während die Luftfiltereinheiten 21 an der Oberseite der Schaltschränke 23 angeordnet sind, befinden sich an deren Unterseite Luftausströmöffnungen, die von einem Ansaugtrichter 25 eines Ansaugschlauches 27 der Gebläseeinheit 19 überdeckt sind. Die Art der Anordnung gewährleistet, dass die Schaltschränke von gefilterter Ansaugluft der Gebläse durchströmt und ihre elektrischen und elektronischen Komponenten aktiv gekühlt werden, bevor diese (leicht erwärmte) Kühlluft in den Strahlungstrockner gelangt und dort die Strahlerelemente und Reflektoren kühlt, wie die Pfeile in der Figur verdeutlichen. Fig. 3 schematically illustrates a prefabricated mounting configuration 15 of a dryer 1 of the in Fig. 1 shown, inserted into a steel profile frame 17. This profile frame forms an enclosure of the radiation dryer 1, in which this can be transported and placed on site. Within the frame 17 next to the actual dryer fan units 19 with input side associated air filter units 21 and - positioned downstream of the large air filter units - control cabinets 23 for the power control of the radiator elements of the radiation dryer 1 housed. While the air filter units 21 are arranged on the upper side of the control cabinets 23, there are air discharge openings on the underside thereof, which are covered by an intake funnel 25 of a suction hose 27 of the blower unit 19. The nature of the arrangement ensures that the cabinets are filtered by filtered intake air from the fans and their electrical and electronic components are actively cooled before this (slightly warmed) cooling air enters the radiation dryer where it cools the radiator elements and reflectors, as the arrows in the figure clarify.

Die Ausführung der Erfindung ist nicht auf die oben beschriebenen Beispiele und hervorgehobenen Aspekte beschränkt, sondern ebenso in einer Vielzahl von Abwandlungen möglich, die im Rahmen fachgemäßen Handelns liegen.The embodiment of the invention is not limited to the examples and highlighted aspects described above, but also possible in a variety of modifications, which are within the scope of technical action.
