Definitions

- This technology employs high power irradiation equipment which efficiently enables the provision of said near infrared (NIR) radiation with the required high power densities and has sufficient life for industrial use.
- the irradiation systems realized by the applicant include radiator modules of the generic type, as described in the (unpublished) German patent applications 100 51 904.0 and 100 51 641.6.

- emitter modules with only one emitter and a partially elliptical reflection surface, which are also referred to as line emitters.
- control devices which allow the individual or group-wise control of the emitter of the irradiation system.
- a controlled process control with evaluation of contactless temperature values detected on the workpiece is desired.
- the required control electronics are usually housed in a control cabinet and in addition to suitable signal processing and optional control stages and the required input and display means, in particular power controller for power control of the emitter.
- the power controllers are each connected to the individually controlled emitter via separate power supply lines.
- the construction of a high-power irradiation system of the type in question here therefore requires the laying of a large number of supply lines from the control cabinet to the radiator modules and is correspondingly labor-intensive and error-prone.
- the power controllers require a relatively large amount of installation space in the control cabinet, because they are provided with voluminous heat sinks due to the considerable heat development.
- the emitter is desirable for early detection of impending failures.
- a distance detection and monitoring between the emitters or radiator modules and the workpiece is required or at least desirable.
- a large number of measured values are also transmitted, which are transmitted from the radiator modules via measuring lines to the control cabinet and processed there. The laying of these lines increases the cost of the plant further, involves additional error and failure risks and contributes significantly to the fact that such a system according to the prior art is not very "handy".
- the invention is therefore an object of the invention to provide an improved radiator module of the generic type and an improved high-power irradiation system, the structure of which is possible with reduced effort and error and failure risk.
- the irradiation system should be compact and clear and easy to configure for various machining processes.
- radiator module having the features of claim 1 and according to a further essential aspect by a high-power irradiation system having the features of claim 13.
- the invention includes on the one hand the essential idea of outsourcing the switching control unit or units from the central system control (the control cabinet) and their displacement to the radiator module. It further includes the idea to use the provided in the radiator modules active cooling of the reflector body at the same time for cooling the switching control elements by these are brought into thermal contact with the reflector body. In addition to saving a considerable Number of separate supply and control lines thus a significant space savings for the switching control units realized by eliminating the need for separate cooling channels.
- the central system control can therefore be much more compact.
- this further includes the idea of equipping the switching control unit or units of the irradiation system with additional "intelligence", ie with monitoring or control means, which are otherwise assigned to the central system control, ie arranged in the control cabinet.
- additional "intelligence" ie with monitoring or control means, which are otherwise assigned to the central system control, ie arranged in the control cabinet.
- Certain functions of the condition monitoring of the emitter - in particular for the purpose of a pre-detection to determine the correct replacement time - can be made more meaningful on the switching control unit itself (especially if it is mounted directly on the radiator module).
- their implementation saves directly at the switching control unit or the radiator module, the signal transmission to the central system control and thus also the corresponding signal lines or transmission links.
- the switching control unit comprises separate control means - in particular power controller - for separate control of several emitters and correspondingly separate outputs for supply lines leading to the individual emitters.
- each individual emitter can be controlled separately and optionally regulated, which can easily build a differentiated NIR irradiation profile of a workpiece and the aging state of the individual emitter can be considered in the control.
- groups of individual emitters can also be controlled together - with which the component expenditure for the control can be reduced, but on the other hand not the same flexibility as in the individual control is achieved.
- modular prefabricated hardwirings eg circuit boards
- circuit boards eg circuit boards
- a wireless signal receiving unit in the switching control unit for wireless signal transmission from and to the central system control makes sense.
- the control signals from the central control unit in particular according to the DECT or Bluetooth standard to the switching control unit or the switching control units can be transmitted without signal lines must be laid.
- a mobile radio link according to the GSM or UMTS standard or a future standard suitable for industrial applications even though their expediency should, of course, be weighed against the use of an in-house transmission link from a cost perspective.
- the switch control unit preferably has a bus interface according to one of the usual industry standards, which allows the connection to a control signal bus of the system control. This may in particular be a Profibus or Ethernet connection.
- radiator modules are individually electronically marked in an expedient development of the inventive concept, so that they can be identified in an overall system at startup - or periodically during operation - and optionally supplied with individual control signals.
- the corresponding identifier is stored in a suitable radiator module code memory and provides information, for example, about the design of the emitter, the design of the reflector, the start of operation or other characteristic variables-but in the simplest case, it can also be just an identification number .
- a radiator module code transmitter which in particular reacts to an interrogation signal from the system controller and transmits the identifier stored in the radiator module code memory, serves for transmission to the system controller.
- a corresponding detection stage is provided which receives and decrypts these signals and provides the data obtained to the actual system control.
- a registration control which implements the transmission of a standby signal of the individual radiator modules when the irradiation system is put into operation, that is, to a certain extent, a "log in” of the modules during plant control.
- This application is preferably - but not necessarily - under transmission of the radiator module code.
- the emitters are - in itself known from the above-mentioned documents or unpublished patent applications - preferably elongated tubular high-performance halogen lamps, which are connected externally in particular via plug contacts in the reflector body.
- the reflector body preferably has cooling channels for passing a cooling fluid, in particular cooling water, and standardized connections for connection to a corresponding cooling system.
- the switching control unit and the optionally provided hard-wired modules are expediently screwed or plugged onto the reflector body, which is preferably flat at the rear.
- the radiator module at least one - in particular non-contact - - sensor integrated or integrated, whose detection range is aligned with a workpiece to be heated and which serves to detect its temperature in the machining process and / or other process-related parameters. Between this sensor or the sensors and the switching control unit is preferably provided a direct Meßsignalinformation.
- the switching control unit comprises a measuring signal processing unit, which provides an input signal for the control or a regulation of the operation of the emitter of the radiator module.
- the corresponding identifier can be contained in the above-mentioned radiator module code, but on the other hand it can also be stored in a separate sensor code memory, particularly in the case of a subsequent supplementation of the radiator module with sensor.
- the transmission to the plant control On the one hand, the transmission is possible together with the radiator module code via the radiator module code transmitter and, on the other hand, a separate interrogation and transmission by means of a dedicated transducer code transmitter. With this design it is always possible to provide the system control with the latest information about the sensors available in the individual radiator module (and of important parameters of the same).
- the detection of various further process parameters may be expedient for determining the optimum power range of the emitter in the machining process. It proves to be advantageous if these parameters, for example, with respect to the process speed, the material or special material properties of the workpiece or its residence time under the radiator module, are obtained separately.
- the acquisition of measured values is integrated into the process, which provide information about the specific application behavior of the emitter / emitter in the concrete plant in terms of their performance and their life cycle.

- the switching control unit 17 has a power supply terminal 19 and a control signal terminal 21 for connection to a central control unit of the irradiation facility.
- the switching control unit 17 Via a wiring board 23 with conductor tracks 23a, the switching control unit 17 is connected to the pads 15 of the emitter 7 and supplies them with a voltage controlled by the power controller operating voltage.
- the power switching devices within the switching control unit 17 are arranged in direct thermal contact with the solid, cooled reflector body 3, so that they are cooled over this and separate cooling means are not required. As a result, the construction volume of the shift control unit 17 can be kept relatively small.
- the wiring boards 23 are designed so that with them - if necessary, by longitudinally predetermined parts Division lines or addition of multiple boards - a simple configuration of the emitter power supply of different irradiation arrangement is possible without disturbing cable strands.

Description
Die Erfindung betrifft ein Strahlermodul nach dem Oberbegriff des Anspruchs 1 sowie eine Hochleistungs-Bestrahlungsanlage nach dem Oberbegriff des Anspruchs 13.The invention relates to a radiator module according to the preamble of
Die Durchführung vielgestaltiger thermischer Bearbeitungsprozesse unter Erwärmung des jeweiligen Werkstücks durch elektromagnetische Strahlung im Bereich des nahen Infrarot, insbesondere mit einem wesentlichen Wirkanteil im Wellenlängenbereich zwischen 0,8 µm und 1,5 µm, ist eine neue, hochgradig leistungsfähige und wirtschaftlich vielversprechende Technologie ("NIR-Technologie"). Wichtige Anwendungsbereiche dieser Technologie sind die Trocknung und Vernetzung von Lacken und anderen Beschichtungen, insbesondere auf temperatursensitiven Substraten, die Trocknung von Druckfarben und Klebstoffen und die Herstellung von Werkstoffverbunden - wie beispielsweise in den auf die Anmelderin zurückgehenden Druckschriften WO 99/42774 und WO 99/42276 beschrieben.The implementation of multifarious thermal machining processes with heating of the respective workpiece by electromagnetic radiation in the near infrared region, in particular with a significant active component in the wavelength range between 0.8 microns and 1.5 microns, is a new, highly efficient and economically promising technology ("NIR -Technology"). Important areas of application of this technology are the drying and crosslinking of paints and other coatings, in particular on temperature-sensitive substrates, the drying of printing inks and adhesives and the production of composite materials - such as in the applicant's references WO 99/42774 and WO 99/42276 described.
Bei dieser Technologie kommen Hochleistungs-Bestrahlungsanlagen zum Einsatz, die die Bereitstellung der besagten Strahlung im Bereich des nahen Infrarot (NIR-Strahlung) mit den erforderlichen hohen Leistungsdichten in effizienter Weise erlauben und eine für den industriellen Einsatz ausreichende Lebensdauer aufweisen. Die seitens der Anmelderin realisierten Bestrahlungsanlagen umfassen Strahlermodule der gattungsgemäßen Art, wie sie in den (unveröffentlichten) deutschen Patentanmeldungen 100 51 904.0 und 100 51 641.6 beschrieben sind.This technology employs high power irradiation equipment which efficiently enables the provision of said near infrared (NIR) radiation with the required high power densities and has sufficient life for industrial use. The irradiation systems realized by the applicant include radiator modules of the generic type, as described in the (unpublished)
Derartige Strahlermodule haben einen massiven metallischen Reflektorkörper mit Kühlkanälen zur Wasserkühlung. In den Reflektorkörper sind üblicherweise mehrere als Emitter dienende langgestreckt röhrenförmige Halogen-Glühfadenlampen eingesetzt, und er hat für jeden Emitter einen geeignet geformten Reflektorabschnitt. Für spezielle Anwendungen gibt es Strahlermodule mit nur einem Emitter und einer teil-elliptischen Reflexionsfläche, die auch als Linienstrahler bezeichnet werden. Mit mehreren derartigen aktiven Strahlermodulen und/oder zusätzlichen, bevorzugt ebenfalls aktiv gekühlten, Reflektormodulen lassen sich weitgehend geschlossene Strahlungsräume zur energieökonomischen Durchführung der verschiedensten thermischen Bearbeitungsvorgänge aufbauen.Such radiator modules have a solid metallic reflector body with cooling channels for water cooling. In the reflector body usually serving as an emitter long elongated tubular halogen filament lamps are used, and He has for each emitter a suitably shaped reflector section. For special applications, there are emitter modules with only one emitter and a partially elliptical reflection surface, which are also referred to as line emitters. With a plurality of such active radiator modules and / or additional, preferably also actively cooled, reflector modules can be built largely closed radiation spaces for energy-economic implementation of various thermal processing operations.
Zur differenzierten Steuerung derartiger Bearbeitungsvorgänge sind Steuereinrichtungen vorgesehen, die die einzelne oder gruppenweise Ansteuerung der Emitter der Bestrahlungsanlage erlauben. Vielfach ist auch eine geregelte Prozeßführung unter Auswertung von berührungslos am Werkstück erfaßten Temperaturwerten erwünscht. Die erforderliche Steuerelektronik ist üblicherweise in einem Schaltschrank untergebracht und umfaßt neben geeigneten Signalverarbeitungs- und wahlweise Regelstufen sowie den erforderlichen Eingabe- und Anzeigemitteln insbesondere Leistungssteller zur Leistungssteuerung der Emitter.For differentiated control of such processing operations control devices are provided which allow the individual or group-wise control of the emitter of the irradiation system. In many cases, a controlled process control with evaluation of contactless temperature values detected on the workpiece is desired. The required control electronics are usually housed in a control cabinet and in addition to suitable signal processing and optional control stages and the required input and display means, in particular power controller for power control of the emitter.
Die Leistungssteller sind mit den einzeln anzusteuernden Emitter jeweils über separate Stromversorgungsleitungen verbunden. Der Aufbau einer Hochleistungs-Bestrahlungsanlage der hier in Rede stehenden Art erfordert daher das Verlegen einer großen Anzahl von Versorgungsleitungen von dem Schaltschrank zu den Strahlermodulen und ist entsprechend arbeitsaufwendig und fehleranfällig. Die Leistungssteller benötigen im Schaltschrank relativ viel Installationsraum, weil sie aufgrund der erheblichen Wärmeentwicklung mit voluminösen Kühlkörpern versehen sind.The power controllers are each connected to the individually controlled emitter via separate power supply lines. The construction of a high-power irradiation system of the type in question here therefore requires the laying of a large number of supply lines from the control cabinet to the radiator modules and is correspondingly labor-intensive and error-prone. The power controllers require a relatively large amount of installation space in the control cabinet, because they are provided with voluminous heat sinks due to the considerable heat development.
Weiterhin ist für eine präzise Prozeßsteuerung und zuverlässige Betriebsführung in der Regel nicht nur die erwähnte Temperaturerfassung, sondern auch eine Erfassung des aktuellen Betriebszustandes der Emitter zur frühzeitigen Erfassung bevorstehender Ausfälle wünschenswert. Für spezielle Anwendungen ist auch eine Abstandserfassung und -überwachung zwischen den Emittern bzw. Strahlermodulen und dem Werkstück erforderlich oder zumindest wünschenswert. Es fällt also bei einer Hochleistungs-Bestrahlungsanlage zur NIR-Bestrahlung auch eine Vielzahl von Meßwerten an, die von den Strahlermodulen über Meßleitungen zum Schaltschrank übertragen und dort verarbeitet werden. Die Verlegung dieser Leitungen erhöht den Gestehungsaufwand der Anlage weiter, birgt zusätzliche Fehler- und Ausfallrisiken und trägt wesentlich dazu bei, daß eine solche Anlage nach dem Stand der Technik wenig "handlich" ist.Furthermore, not only the mentioned temperature detection, but also a detection of the current operating state for a precise process control and reliable operation the emitter is desirable for early detection of impending failures. For specific applications, a distance detection and monitoring between the emitters or radiator modules and the workpiece is required or at least desirable. Thus, in the case of a high-power irradiation system for NIR irradiation, a large number of measured values are also transmitted, which are transmitted from the radiator modules via measuring lines to the control cabinet and processed there. The laying of these lines increases the cost of the plant further, involves additional error and failure risks and contributes significantly to the fact that such a system according to the prior art is not very "handy".
Der Erfindung liegt daher die Aufgabe zugrunde, ein verbessertes Strahlermodul der gattungsgemäßen Art sowie eine verbesserte Hochleistungs-Bestrahlungsanlage anzugeben, deren Aufbau mit verringertem Arbeitsaufwand sowie Fehler- und Ausfallrisiko möglich ist. Die Bestrahlungsanlage soll kompakt und übersichtlich und leicht für verschiedenartige Bearbeitungsprozesse konfigurierbar sein.The invention is therefore an object of the invention to provide an improved radiator module of the generic type and an improved high-power irradiation system, the structure of which is possible with reduced effort and error and failure risk. The irradiation system should be compact and clear and easy to configure for various machining processes.
Diese Aufgabe wird gemäß einem ersten wesentlichen Aspekt der Erfindung durch ein Strahlermodul mit den Merkmalen des Anspruchs 1 und gemäß einem weiteren wesentlichen Aspekt durch eine Hochleistungs-Bestrahlungsanlage mit den Merkmalen des Anspruchs 13 gelöst.This object is achieved according to a first essential aspect of the invention by a radiator module having the features of
Die Erfindung schließt zum einen den wesentlichen Gedanken einer Auslagerung der Schaltsteuereinheit bzw. -einheiten aus der zentralen Anlagensteuerung (dem Schaltschrank) und ihrer Verlagerung an das Strahlermodul ein. Sie schließt weiter den Gedanken ein, die in den Strahlermodulen vorgesehene aktive Kühlung des Reflektorkörpers zugleich zur Kühlung der Schaltsteuerelemente zu nutzen, indem diese in thermischen Kontakt mit dem Reflektorkörper gebracht werden. Neben der Einsparung einer erheblichen Anzahl von separaten Versorgungs- bzw. Ansteuerleitungen wird damit auch eine erhebliche Platzersparnis für die Schaltsteuereinheiten realisiert, indem auf gesonderte Kühlkanäle verzichtet werden kann. Die zentrale Anlagensteuerung kann daher wesentlich kompakter werden. Dies ermöglicht gegebenenfalls den Verzicht auf einen regelrechten Schaltschrank und eine Plazierung der kompakten zentralen Steuereinheit der NIR-Bestrahlungsanlage direkt bei einem Prozeßrechner einer Gesamt-Produktionsanlage oder aber unmittelbar an der in die Gesamtanlage eingefügten NIR-Bestrahlungsvorrichtung.The invention includes on the one hand the essential idea of outsourcing the switching control unit or units from the central system control (the control cabinet) and their displacement to the radiator module. It further includes the idea to use the provided in the radiator modules active cooling of the reflector body at the same time for cooling the switching control elements by these are brought into thermal contact with the reflector body. In addition to saving a considerable Number of separate supply and control lines thus a significant space savings for the switching control units realized by eliminating the need for separate cooling channels. The central system control can therefore be much more compact. This makes it possible, if appropriate, to dispense with a veritable control cabinet and to place the compact central control unit of the NIR irradiation system directly in a process computer of an overall production plant or directly on the NIR irradiation device inserted in the overall system.
Gemäß einem relativ selbständigen Aspekt der Erfindung schließt diese weiterhin den Gedanken ein, die Schaltsteuereinheit bzw. -einheiten der Bestrahlungsanlage mit zusätzlicher "Intelligenz" auszurüsten, also mit Überwachungs- bzw. Ansteuermitteln, welche ansonsten der zentralen Anlagensteuerung zugeordnet, also im Schaltschrank angeordnet sind. Bestimmte Funktionen der Zustandsüberwachung der Emitter - insbesondere zum Zweck einer Vorausfallsdetektion zur Bestimmung des richtigen Ersatzzeitpunktes - lassen sich an der Schaltsteuereinheit selbst (insbesondere dann, wenn diese direkt am Strahlermodul angebracht ist) sinnvoller ausführen. Zudem spart ihre Realisierung direkt bei der Schaltsteuereinheit bzw. dem Strahlermodul die Signalübertragung zur zentralen Anlagensteuerung und damit auch die entsprechenden Signalleitungen bzw. Übertragungsstrecken ein. Schließlich ist ihre Realisierung in räumlicher Zuordnung zur Schaltsteuereinheit bzw. den Emittern auch insofern vorteilhaft, als im Ergebnis der Auswertung abgeleitete Steuersignale unmittelbar an dem Ort zur Verfügung stehen, wo sie gebraucht werden. Es sind daher also auch Vereinfachungen und Einsparungen bei Steuerleitungen bzw. sonstigen Steuersignal-Übertragungsstrecken zu realisieren.According to a relatively independent aspect of the invention, this further includes the idea of equipping the switching control unit or units of the irradiation system with additional "intelligence", ie with monitoring or control means, which are otherwise assigned to the central system control, ie arranged in the control cabinet. Certain functions of the condition monitoring of the emitter - in particular for the purpose of a pre-detection to determine the correct replacement time - can be made more meaningful on the switching control unit itself (especially if it is mounted directly on the radiator module). In addition, their implementation saves directly at the switching control unit or the radiator module, the signal transmission to the central system control and thus also the corresponding signal lines or transmission links. Finally, their implementation in spatial allocation to the switching control unit or the emitters is also advantageous in that, as a result of the evaluation, derived control signals are directly available at the location where they are needed. Therefore, it is also simplifications and savings in control lines or other control signal transmission links to realize.
In einer bevorzugten Ausführung umfaßt die Schaltsteuereinheit getrennte Steuermittel - insbesondere Leistungssteller - zur separaten Ansteuerung mehrerer Emitter und entsprechend getrennte Ausgänge für zu den einzelnen Emittern führende Versorgungsleitungen. In dieser Ausführung läßt sich jeder einzelne Emitter separat steuern und gegebenenfalls regeln, wodurch sich in einfacher Weise ein differenziertes NIR-Bestrahlungsprofil eines Werkstücks aufbauen und der Alterungszustand der einzelnen Emitter in der Ansteuerung berücksichtigen läßt. Ebenso können auch Gruppen einzelner Emitter zusammen angesteuert werden - womit der Bauelementeaufwand bei der Ansteuerung reduziert werden kann, jedoch andererseits nicht die gleiche Flexibilität wie bei der Einzel-Ansteuerung erreicht wird.In a preferred embodiment, the switching control unit comprises separate control means - in particular power controller - for separate control of several emitters and correspondingly separate outputs for supply lines leading to the individual emitters. In this embodiment, each individual emitter can be controlled separately and optionally regulated, which can easily build a differentiated NIR irradiation profile of a workpiece and the aging state of the individual emitter can be considered in the control. Likewise, groups of individual emitters can also be controlled together - with which the component expenditure for the control can be reduced, but on the other hand not the same flexibility as in the individual control is achieved.
Zur Verbindung zwischen den Thyristerstellern und den Emittern sind in einer weiter bevorzugten Ausführung modular vorgefertigte Festverdrahtungen (z. B. Platinen) vorgesehen, die direkt auf den Reflektorkörper montiert werden können. Hierdurch werden auf besonders einfache Weise spezifische Bestrahlungskonfigurationen realisierbar, und "Kabelsalat" wird nahezu vollständig beseitigt.For the connection between the thyristor actuators and the emitters, in a further preferred embodiment, modular prefabricated hardwirings (eg circuit boards) are provided which can be mounted directly on the reflector body. As a result, specific irradiation configurations can be realized in a particularly simple manner, and "cable clutter" is almost completely eliminated.
In diesem Sinne ist desweiteren das Vorsehen einer drahtlosen Signalempfangseinheit bei der Schaltsteuereinheit zur drahtlosen Signalübertragung von und zu der zentralen Anlagensteuerung sinnvoll. In dieser Ausführung können die Steuersignale von der zentralen Steuereinheit insbesondere nach dem DECT- oder Bluetooth-Standard zur Schaltsteuereinheit oder den Schaltsteuereinheiten übertragen werden, ohne daß Signalleitungen verlegt werden müssen. Auch die Nutzung einer Mobilfunkstrecke nach dem GSM- oder dem UMTS- oder einem künftigen, für industrielle Anwendungen geeigneten Standard ist möglich - wenn auch deren Zweckmäßigkeit natürlich unter Kostengesichtspunkten gegen den Einsatz einer betriebsinternen Übertragungsstrecke abzuwägen ist.In this sense, further, the provision of a wireless signal receiving unit in the switching control unit for wireless signal transmission from and to the central system control makes sense. In this embodiment, the control signals from the central control unit, in particular according to the DECT or Bluetooth standard to the switching control unit or the switching control units can be transmitted without signal lines must be laid. It is also possible to use a mobile radio link according to the GSM or UMTS standard or a future standard suitable for industrial applications - even though their expediency should, of course, be weighed against the use of an in-house transmission link from a cost perspective.
Alternativ ist natürlich auch das Vorsehen eines Signalleitungsanschlusses an der oder jeder Schaltsteuereinheit zur leitungsgebundenen Signalverbindung mit der Anlagensteuerung möglich. In beiden Ausführungen hat die Schaltsteuereinheit bevorzugt eine Bus-Schnittstelle nach einem der üblichen Industriestandards, die den Anschluß an einen Steuersignalbus der Anlagensteuerung ermöglicht. Es kann sich hierbei insbesondere um eine Profibus- oder Ethernet-Verbindung handeln.Alternatively, of course, it is also possible to provide a signal line connection to the or each switching control unit for the line-connected signal connection with the system control. In both embodiments, the switch control unit preferably has a bus interface according to one of the usual industry standards, which allows the connection to a control signal bus of the system control. This may in particular be a Profibus or Ethernet connection.
Die Strahlermodule sind in einer zweckmäßigen Fortbildung des Erfindungsgedankens individuell elektronisch markiert, so daß sie in einer Gesamtanlage bei Inbetriebnahme - oder auch periodisch während des Betriebes - identifiziert und gegebenenfalls mit individuellen Steuersignalen versorgt werden können. Die entsprechende Kennung wird bei Konfiguration des Strahlermoduls in einen geeigneten Strahlermodul-Codespeicher eingespeichert und gibt beispielsweise Auskunft über die Bauart der Emitter, die Bauart des Reflektors, den Betriebsbeginn oder andere charakteristische Größen - es kann sich im einfachsten Fall aber auch nur um eine Kennnummer handeln. Zur Übermittlung an die Anlagensteuerung dient ein Strahlermodul-Codesender, der insbesondere auf ein Abfragesignal von der Anlagensteuerung hin aktiv wird und die im Strahlermodul-Codespeicher gespeicherte Kennung überträgt. In der Anlagensteuerung ist eine entsprechende Erkennungsstufe vorgesehen, die diese Signale empfängt und entschlüsselt und die gewonnenen Daten der eigentlichen Anlagensteuerung bereitstellt.The radiator modules are individually electronically marked in an expedient development of the inventive concept, so that they can be identified in an overall system at startup - or periodically during operation - and optionally supplied with individual control signals. When the radiator module is configured, the corresponding identifier is stored in a suitable radiator module code memory and provides information, for example, about the design of the emitter, the design of the reflector, the start of operation or other characteristic variables-but in the simplest case, it can also be just an identification number , A radiator module code transmitter, which in particular reacts to an interrogation signal from the system controller and transmits the identifier stored in the radiator module code memory, serves for transmission to the system controller. In the system control, a corresponding detection stage is provided which receives and decrypts these signals and provides the data obtained to the actual system control.
In einer Fortführung dieses Gedankens ist eine Anmeldesteuerung vorgesehen, die die Übertragung eines Bereitschaftssignals der einzelnen Strahlermodule bei Inbetriebnahme der Bestrahlungsanlage, also gewissermaßen ein "Einloggen" der Module bei der Anlagensteuerung, realisiert. Diese Anmeldung erfolgt vorzugsweise - aber nicht notwendigerweise - unter Übermittlung des Strahlermodulcodes.In a continuation of this idea, a registration control is provided which implements the transmission of a standby signal of the individual radiator modules when the irradiation system is put into operation, that is, to a certain extent, a "log in" of the modules during plant control. This application is preferably - but not necessarily - under transmission of the radiator module code.
Bei den Emittern handelt es sich - in an sich aus den oben genannten Druckschriften bzw. unveröffentlichten Patentanmeldungen bekannterweise - bevorzugt um langgestreckt röhrenförmige Hochleistungs-Halogenlampen, die insbesondere über Steckkontakte in dem Reflektorkörper extern angeschlossen sind. Der Reflektorkörper hat bevorzugt Kühlkanäle zum Durchleiten eines Kühlfluids, insbesondere von Kühlwasser, und genormte Anschlüsse zum Anschluß an eine entsprechende Kühlanlage.The emitters are - in itself known from the above-mentioned documents or unpublished patent applications - preferably elongated tubular high-performance halogen lamps, which are connected externally in particular via plug contacts in the reflector body. The reflector body preferably has cooling channels for passing a cooling fluid, in particular cooling water, and standardized connections for connection to a corresponding cooling system.
Die Schaltsteuereinheit und die wahlweise vorgesehenen Festverdrahtungsmodule sind auf den - rückseitig bevorzugt eben ausgeführten - Reflektorkörper zweckmäßigerweise aufgeschraubt oder aufgesteckt.The switching control unit and the optionally provided hard-wired modules are expediently screwed or plugged onto the reflector body, which is preferably flat at the rear.
In das Strahlermodul ist bevorzugt mindestens ein - insbesondere berührungslos arbeitender - Meßfühler integriert oder integrierbar, dessen Erfassungsbereich auf ein zu erhitzendes Werkstück ausgerichtet ist und der zur Erfassung von dessen Temperatur im Bearbeitungsprozeß und/oder anderen prozeßrelevanten Parametern dient. Zwischen diesem Meßfühler oder den Meßfühlern und der Schaltsteuereinheit ist bevorzugt eine direkte Meßsignalverbindung vorgesehen. Die Schaltsteuereinheit umfaßt eine Meßsignal-Verarbeitungseinheit, welche ein Eingangssignal für die Steuerung bzw. eine Regelung des Betriebes der Emitter des Strahlermoduls liefert.In the radiator module at least one - in particular non-contact - - sensor integrated or integrated, whose detection range is aligned with a workpiece to be heated and which serves to detect its temperature in the machining process and / or other process-related parameters. Between this sensor or the sensors and the switching control unit is preferably provided a direct Meßsignalverbindung. The switching control unit comprises a measuring signal processing unit, which provides an input signal for the control or a regulation of the operation of the emitter of the radiator module.
Ähnlich zur oben erwähnten Kennzeichnung des Strahlermoduls durch einen geeigneten Code ist in vorteilhafter Weise auch eine Kennzeichnung der integrierten Sensorik möglich. Die entsprechende Kennung kann einerseits in dem oben erwähnten Strahlermodulcode enthalten sein, andererseits aber auch - insbesondere bei einer nachträglichen Ergänzung des Strahlermoduls mit Sensorik - in einem gesonderten Meßfühler-Codespeicher abgelegt sein. Auch bezüglich der Übertragung an die Anlagensteuerung ist zum einen die Übertragung zusammen mit dem Strahlermodulcode über den Strahlermodul-Codesender und zum anderen eine separate Abfrage und Übertragung durch einen dedizierten Meßfühler-Codesender möglich. Mit dieser Ausführung ist es jederzeit möglich, der Anlagensteuerung die aktuellsten Informationen über die im einzelnen Strahlermodul verfügbare Sensorik (und von wichtigen Parametern derselben) zur Verfügung zu stellen.Similar to the above-mentioned marking of the radiator module by a suitable code, an identification of the integrated sensor system is also possible in an advantageous manner. On the one hand, the corresponding identifier can be contained in the above-mentioned radiator module code, but on the other hand it can also be stored in a separate sensor code memory, particularly in the case of a subsequent supplementation of the radiator module with sensor. Also regarding the transmission to the plant control On the one hand, the transmission is possible together with the radiator module code via the radiator module code transmitter and, on the other hand, a separate interrogation and transmission by means of a dedicated transducer code transmitter. With this design it is always possible to provide the system control with the latest information about the sensors available in the individual radiator module (and of important parameters of the same).
Neben der oben speziell erwähnten Temperaturerfassung ist zur Bestimmung des optimalen Leistungsbereiches der Emitter im Bearbeitungsprozeß gegebenenfalls die Erfassung diverser weiterer Prozeßparameter zweckmäßig. Hierbei erweist es sich als vorteilhaft, wenn diese Parameter, beispielsweise bezüglich der Prozeßgeschwindigkeit, des Materials oder spezieller Materialeigenschaften des Werkstücks bzw. dessen Verweilzeit unter dem Strahlermodul, jeweils separat gewonnen werden. Zweckmäßigerweise wird auch die Erfassung von Meßwerten in den Prozeß integriert, die Aufschluß über das spezifische Einsatzverhalten des Emitters/der Emitter in der konkreten Anlage bezüglich ihrer Leistungsfähigkeit und ihres Lebenszyklus geben.In addition to the temperature detection specifically mentioned above, the detection of various further process parameters may be expedient for determining the optimum power range of the emitter in the machining process. It proves to be advantageous if these parameters, for example, with respect to the process speed, the material or special material properties of the workpiece or its residence time under the radiator module, are obtained separately. Advantageously, the acquisition of measured values is integrated into the process, which provide information about the specific application behavior of the emitter / emitter in the concrete plant in terms of their performance and their life cycle.

Fig. 1 zeigt in einer vereinfachten perspektivischen Darstellung ein Strahlermodul 1 einer NIR-Bestrahlungsanlage, wobei ein Reflektorkörper 3 nahe seinem einen Ende geschnitten dargestellt und von mehreren Rahmenteilen, die zur Halterung und Kühlfluidzuführung dienen, nur ein Rahmenteil 5 schematisch dargestellt ist. Das Strahlermodul 1 ist zur Aufnahme von sechs langgestreckt röhrenförmigen Halogen-Glühfadenlampen (Emittern) 7 ausgebildet.Fig. 1 shows a simplified perspective view of a
Der Reflektorkörper 3 ist als Strangpreßprofil aus einer massiven Aluminiumlegierung gefertigt und hat eingeformte Kühlwasserkanäle 9 sowie jeweils einem Emitter 7 zugeordnete, annähernd W-förmige Reflektorabschnitte 11 mit polierter Oberfläche. Die Halogenlampen 7 sind über Steckkontakte 13 an ihren Enden, die isoliert durch den Reflektorkörper 3 geführt sind, mit Anschlußflächen 15 auf der Rückseite des Reflektorkörpers verbunden.The
Auf die Rückseite des Reflektorkörpers 3 ist desweiteren eine Schaltsteuereinheit 17 montiert, welche (nicht einzeln dargestellte) Leistungssteller zur Stromversorgung und Ansteuerung der Emitter 7 umfaßt. Die Schaltsteuereinheit 17 hat einen Stromversorgungsanschluß 19 und einen Steuersignalanschluß 21 zur Verbindung mit einer zentralen Steuereinheit der Bestrahlungsanlage. Über eine Verdrahtungsplatine 23 mit Leiterzügen 23a ist die Schaltsteuereinheit 17 mit den Anschlußflächen 15 der Emitter 7 verbunden und versorgt diese mit einer über die Leistungssteller gesteuerten Betriebsspannung. Die Leistungsschalt-Bauelemente innerhalb der Schaltsteuereinheit 17 sind im direkten thermischen Kontakt mit dem massiven, gekühlten Reflektorkörper 3 angeordnet, so daß sie über diesen gekühlt werden und gesonderte Kühlmittel nicht erforderlich sind. Dadurch kann das Bauvolumen der Schaltsteuereinheit 17 relativ klein gehalten werden. Die Verdrahtungsplatinen 23 sind derart gestaltet, daß mit ihnen - gegebenenfalls durch Teilen längs vorgegebener Teilungslinien bzw. Addition mehrerer Platinen - eine einfache Konfiguration der Emitter-Stromversorgung verschiedener Bestrahlungsanordnung ohne störende Kabelstränge möglich ist.On the back of the

Die NIR-Bestrahlungsstationen 102, 104 umfassen jeweils zwei Strahlermodule 102A, 102B bzw. 104A, 104B der in Fig. 1 gezeigten Art, die jeweils eine Mehrzahl von separat überwachbaren und steuerbaren Emittern 107 in einem Reflektorkörper 103 sowie eine Schaltsteuereinheit 117 aufweisen. Den Schaltsteuereinheiten 117 ist jeweils eine nach dem DECT-Standard arbeitende Funksende- und -empfangseinheit 118 zugeordnet. Die Funksende- und -empfangseinheiten 118 an den Strahlermodulen realisieren eine drahtlose Meß- und Steuersignalverbindung zwischen den Schaltsteuereinheiten 117 und dem Steuerrechner 110, der an ein entsprechendes DECT-Modul 120 angeschlossen ist.The
Dem Strahlermodul 104A ist ein Pyrometerelement 122 zur berührungslosen Temperaturmessung am Werkstück 106 zugeordnet, welches über eine Meßsignalverbindung mit der Funksende- und - empfangseinheit 118 dieses Strahlermoduls verbunden ist. Über diese werden die Temperaturmeßsignale an den Steuerrechner 110 übermittelt, dort verarbeitet und für die Leistungssteuerung bzw. -regelung der NIR-Bestrahlungsstationen berücksichtigt.The
Über die DECT-Kommunikationsstrecke zwischen den Strahlermodulen und dem Steuerrechner ist eine komplexe Meß- und Steuerdatenkommunikation möglich, ohne daß in der Produktionsanlage 100 zum Betrieb der NIR-Bestrahlungsstationen 102, 104 - abgesehen von Stromversorgungsleitungen, die diese mit einem zentralen Stromversorgungsanschluß 124 verbinden - Leitungen zu verlegen wären. Diese Datenkommunikation umfaßt insbesondere die Übertragung von der Zustandserfassung der Emitter dienenden Spannungs- und Strommeßwerten, der oben erwähnten Temperatursignale und sonstiger im Prozeß gewonnener Meßwerte einerseits sowie aller für den Betrieb der Bestrahlungsanlagen benötigten Steuersignale andererseits.About the DECT communication path between the radiator modules and the control computer is a complex measurement and control data communication possible, without that in the
