Charakteristik des bekannten Standes dor Technik Characteristic of the known state of the art

El 1st bekannt, den Aushärtegrad von Mineralwolleerzeugnissen (Materialbahnen, Platten) mittels nichtzerstörungsfreier Prüfverfahren zu bestimmen. Ogzu werden stichprobenartige Überprüfungen durchgeführt, die zeitintensive Laboruntersuchungen zur Folge haben. Zwangsläufig ergeben sich daraus im HerstellungsprozeÜ längere Produktionsphasen mit verminderten Qualitätsparametern.It is known to determine the degree of cure of mineral wool products (webs, sheets) by non-destructive testing methods. In addition, random checks are carried out, which lead to time-consuming laboratory investigations. Inevitably, this results in longer production phases with reduced quality parameters in the production process.

Eine zerstörungsfreie PrUfung des Aushärtegrades bietet die Lösung gemäß EP 324869, bei dem die Probe eines mit einem Reaktionsharz imprägnierten Trägers in einer PrUfflüssigkeit bewegt wird, ueren Temperatur so gewählt wird, daß das Reaktionsharz aushärten kann, und die fllr das Dewegen der Probe benötigte Energie (z.B. elektrischer Strom) während der Aushärtung gemessen wird.A non-destructive test of the degree of cure is provided by the solution according to EP 324869, in which the sample of a support impregnated with a reaction resin is agitated in a test fluid, the temperature is chosen so that the reaction resin can harden, and the energy required to move the sample ( eg electric current) during curing.

Auch dieses Verfahren ist nur für Stichprobenprüfungen und im Labor anwendbar.Again, this procedure is only applicable to spot checks and in the laboratory.

In der DO-PS 208062 wird ein Verfahren zur Bestimmung der Oichte instabiler Medien mittels radioaktiver Strahlungsabsorption unter Verwendung der Gammastrahlung eines Nuklides dargestellt, wobei das Meßgut einem divergenten Strahlenfeld ausgesetzt wird. Mit diesen Verfahren wird eine kontinuierliche Messung der Dichte von Suspensionen bei der PoIyester-und-seidenherstellung erreicht. Nachteilig ist hierbei zu sehen, daß die Bestimmung der Dichte nur auf ein begrenztes Einsatzgebiet beschränkt ist.In DO-PS 208062 a method for the determination of the ocre of unstable media by means of radioactive radiation absorption using the gamma radiation of a nuclide is shown, wherein the test material is exposed to a divergent radiation field. With these methods, a continuous measurement of the density of suspensions in polyester-and-silk production is achieved. The disadvantage here is to see that the determination of the density is limited to a limited field of application.

Ziel der Erfindung ist es, ein Verfahren bereitzustellen, das die qualitätsgerechte Aushärtung bei dor Herstellung von Materialbahnen während des Produktionsprozesses sichert.The aim of the invention is to provide a method which ensures the quality-oriented curing in the production of material webs during the production process.

Darlegung des Wesens der ErfindungExplanation of the essence of the invention

Aufgabe der Erfindung ist es, das Verfahren zur Herstellung von Materialbahnen derart zu gestalten, daß eine ständige automatische Überwachung des Aushärtegrades an Materialbahnen während des Produktionsprozesses sowie nach dem Auftreten von Mangeln eim sofortige Reaktion des Anlagenpersonals zur Qualitätssicherung erfolgen kann.The object of the invention is to make the method for producing webs such that a constant automatic monitoring of the degree of hardness of webs during the production process and after the occurrence of shortages eim immediate response of the plant staff can be done for quality assurance.

Oie Nachteile bekannter Lösungen (wie zeitintensive Laboruntersuchungen, nur stichprobenartige Überprüfungen sowie längere Produktionsphasen mit verminderten Qualitätsparametern) werden damit vermieden.The disadvantages of known solutions (such as time-consuming laboratory tests, only random checks and longer production phases with reduced quality parameters) are thus avoided.

ErfindungsgemäO wird diese Aufgabe durch den Einsatz einer an sich bekannten radiometrischen Meßanordnung an der Produktionslinie gelöst, wobei unter Anwendung des Durchstrahlungsverfahrens durch mangelhafte Aushärtung entstandene Geometriefehler Über den Absorptionsgrad der Strahlung eines Radionuklides erfaßt und signalisiert werden.According to the invention, this object is achieved by the use of a known radiometric measuring arrangement on the production line, whereby geometry errors resulting from poor curing are detected and signaled via the absorption coefficient of the radiation of a radionuclide using the radiographic method.

Erfindungswesentlich ist dabei, daß die durch das Auftreten des Geometriefehlers verursachte starke Streuung der Strahlung den Absorptionsgrad und damit die vom Meßgerät aufgenommene Strahlung verändert. Unterschreitet die Strahlungsintensität einen einstellbaren Sollwert, so wird ein Fehlersignal ausgelöst.It is essential to the invention that the strong scattering of the radiation caused by the occurrence of the geometry error alters the degree of absorption and thus the radiation received by the measuring device. If the radiation intensity falls below an adjustable setpoint, an error signal is triggered.

üie Erfindung wird nachfolgend an einem AusfUhrungsbeispiel näher erläutert.üie invention will be explained in more detail below to a AusfUhrungsbeispiel.

Bei der Herstellung von Mineralwolleerzeugnissen werden deren geschmolzene Ausgangsstoffe zu Fasermaterialbahnen (-platten oder -matten) verarbeitet, wobei der Aushärtegrad einen wesentlichen Qualitätsparameter für diese Erzeugnisse darstellt. Nichtausgehärtete Mineralwolleerzeugnisse besitzen mehrere Grenzschichten (z.B. ausgehärtete Schicht- nichtausgehärtete Schicht -ausgehärtete Schicht), was zu Inhomogenitäten im Innern der Materialbahn, dem Geometriefehler führt.In the production of mineral wool products, their molten raw materials are processed into fibrous material webs (sheets or mats), whereby the degree of cure represents a significant quality parameter for these products. Unhardened mineral wool products have multiple boundary layers (e.g., cured layer uncured layer-cured layer), resulting in inhomogeneities in the interior of the web, the geometry error.

Um eine qualitätsgerechte Herstellung von Mineralwolleerzeugnissen zu sichern, wird eine ständige automatische überwachung des Aushärtegrades während des Produktionsprozesses nach dem erfindungsgemäßen Verfahren durchgeführt. Dazu werden die Meßmittel, wie Strahlenquelle (Radionuklid) und Strahlungsempfänger (Meßgerät), derart an der Produktionslinie angebracht, daß die dazwischen angeordnete Mineralwollebahn die Meßstrecke bildet. Zur Messung wird die Absorption genutzt, die die Strahlung eines Radionuklides als Folge einer Wechselwirkung mit den Atomen des Meßgutes (Mineralwolle) erfährt. Zur Ermittlung des Aushärtegrades wird weiterhin der Zusammenhang "Transmissionsgrad + Reflexionsgrad + Absorptionsgrad = 1" genutzt, der die Abhängigkeit von Reflexions- und Absorptionsgrad darstellt.In order to ensure a quality production of mineral wool products, a constant automatic monitoring of the degree of curing during the production process is carried out according to the inventive method. For this purpose, the measuring means, such as radiation source (radionuclide) and radiation receiver (measuring device) are mounted on the production line such that the mineral wool web arranged therebetween forms the measuring path. To measure the absorption is used, which experiences the radiation of a radionuclide as a result of an interaction with the atoms of the sample (mineral wool). To determine the degree of cure, the relationship "transmittance + reflectance + degree of absorption = 1" is further used, which represents the dependence of reflection and absorption.

Trifft die radioaktive Strahlung des Radionuklides auf ein nur teilweise ausgehärtetes Mineralwolleerzeugnis, so tritt an den Grenzschichten eine starke Streuung der Strahlung auf, was wiederum eine Änderung des Absorptionsgrades nach sich zieht. Untersuchungen an Mineralwolleplatten ergaben, daß sich die vom Meßgerät aufgenommene Strahlung um ein Mehrfaches verändert und damit ein eindeutiges Erfassen des Geometriefehlers zuläßt.If the radioactive radiation of the radionuclide encounters a partially cured mineral wool product, a strong scattering of the radiation occurs at the boundary layers, which in turn causes a change in the degree of absorption. Investigations on mineral wool slabs showed that the radiation absorbed by the measuring device changed by a multiple and thus allows a clear detection of the geometry error.

Wird das radioaktive Meßgerät auf einen Sollwert (entspricht ausgehärteter Mineralwolleplatte) eingestellt, so wird sofort bei Unterschreiten der Strahlungsintensität ein Fehler-If the radioactive measuring instrument is set to a nominal value (corresponds to hardened mineral wool plate), immediately upon falling below the radiation intensity an error
