Description

Es ist bekannt, daß diese Erfassung der Staubildung zwischen DüseIt is known that this detection of congestion between nozzle

und Kalibrierung über eine mechanisch/elektrische Abtastung durchgeführt wird. Dadurch kann nur an einem Punkt des PrcÎilquerschnittes gemessen werden, und es entsteht eine Schleifspur.and calibration performed via mechanical / electrical scanning will. This means that measurements can only be taken at one point on the cross-section of the product, and a grinding track is created.

Diese rnechanisch/elektrische Abtastung ist sehr reparaturanfällig, und ist gegen äußere Einflüsse ( z.B. Vibrationen, Staub usw. ) überempfindlich.This mechanical / electrical scanning is very susceptible to repair, and is overly sensitive to external influences (e.g. vibrations, dust, etc.).

Der Erfindung liegt die Aufgabe zu Grunde die Staubildung zwischen Dü2- und Kalibrierung an jeder @ante oder Nase des Profilquerschnittes berührungslos abtasten zu können, und gegen äuR.ebe Ein flüsse stand zu halten.The invention is based on the task of congestion between Dü2 and calibration on every edge or nose of the profile cross-section without contact to be able to feel and to withstand external influences.

Die Aufgabe wird erfindungsm&'ßig dadurch gelöst, daß eine Infrarot-Leuchtdiode und ein Infrarot-Fototransistor direkt übereinandersitzen, und diese so zwischen Düse und Kalibrierung angebracht werden, damit sich die gewählte Profilkante im Infrarotlichtkegel befindet.The object is achieved according to the invention in that an infrared light-emitting diode and an infrared phototransistor sit directly on top of each other, and so between Nozzle and calibration are attached so that the selected profile edge is in the Infrared light cone is located.

Di jnfr£-#ot-Leuchtdiode erhält aus dem Regelgerät eine Xo».stantæ annung, d.h. sie bestrahlt den ihr gegenüberliegenden Infrarot-Fototransistor ständig.The jnfr £ - # ot light-emitting diode receives a Xo ».stantæ from the control device warning, i.e. it continuously irradiates the infrared phototransistor opposite it.

Wird nun der Meßkopf an eine Kante des Profils zwischen Düse und Kalibrierung gebracht, so wird das Strahlungsfeld der Infrarot-Leuchtdiode - je nach Staubildung - mehr oder weniger serdeckt.The measuring head is now placed on an edge of the profile between the nozzle and calibration brought, the radiation field of the infrared light-emitting diode - depending on the build-up of congestion - more or less covered.

Dies ruft, da nehr oder weniger Lichtenergie auf dem Infrarot-Fototransistor fällt, in diesem eine Widerstandsänderung hervor, die vom Regelegrät erfasst und entsprechend ausgewertet wird.This causes more or less light energy on the infrared phototransistor falls, in this a resistance change, which is recorded by the control unit and is evaluated accordingly.

Der optische Meßkopf hat die unbedingten Vorteile: a) er ermöglicht eine uberuas präzise Erfassung der Staubildung zwischen Düse und Kalibrierung b) er ermöglicht selbst ständiges Arbeiten der Kunststo ffprofil fertigungsstraßen - keine Ausfallzeiten durch Abriss mehr! c) er ermöglicht eine wesentlich höhere Produktionsgeschwindigkeit mit einer konstanten Produktqualität d) er ist absolut unempfindlich gegen äußere ( meist extreme ) Einflüsse wie z.B. Stoß-Feuchtigkeit-Temperatur-Staub usw.The optical measuring head has the following advantages: a) it enables an uberuas precise detection of the jam formation between nozzle and calibration b) it enables the plastic profile production lines to work continuously - no more downtime due to demolition! c) it allows a much higher Production speed with a constant product quality d) it is absolute insensitive to external (mostly extreme) influences such as shock-humidity-temperature-dust etc.

e) er benötigt keinerlei Reaktionszeit Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt, und wird im folgenden näher beschrieben: 1) Infrarot-Leuchtdiode 2) Infrarot-Fototransistor 3) Verstellmechanismus 4) Anschlußstecker Leerseite e) it does not require any reaction time The invention is shown in the drawing and is described in more detail below: 1) Infrared light emitting diode 2) Infrared phototransistor 3) Adjustment mechanism 4) Connector Blank page

Patentanspruch: Optischer Meßkopf zum Abtasten der Staubildung zwischen DUse und Kalibrierung bei Kunststoffprofilfertigungsstraßen, dadurch gekennzeichnet, daß sich ein Infrarot-Fototransistor und eine Infrarot-Leuchtdiode gegenübersitzen, wobei die Lichtmenge, die von der Leuchtdiode auf den Fototransistor fällt für die Regelung ausschlaggebend ist.Claim: Optical measuring head for scanning the jam formation between DUse and calibration for plastic profile production lines, characterized by that an infrared phototransistor and an infrared light-emitting diode sit opposite each other, where the amount of light that falls from the light emitting diode onto the phototransistor for the Regulation is decisive. Der optische Meßkopf erfasst die Staubildung zwischen Düse und Kalibrierung b e r U h r u n 8 s 1 o s, und bewirkt damit, daß ein angeschlossenes Regelgerät die Abzugsgeschwindigkeit optimal einregelt.The optical measuring head detects the build-up of congestion between the nozzle and the calibration b e r u h r u n 8 s 1 o s, and thus causes a connected control device optimally regulates the withdrawal speed.
