Description
Die Erfindung betrifft eine Linear-Messvorrichtung nach dem Oberbegriff der Patentansprüche 1 bis 3, sowie deren Verfahren zur Herstellung nach den Patentansprüchen 4 und 5. The invention relates to a linear measuring device according to the preamble of claims 1 to 3, and their method of production according to
STAND DER TECHNIK STATE OF THE ART
Aus dem Stand der Technik sind Linear-Messvorrichtungen und -systeme bekannt und gebräuchlich. Es handelt sich dabei um einen Magnetbandaufbau aus einem kunststoffgebunden hartmagnetischen Ferrit auf einem Trägerband aus Stahl, wobei das Magnetband auf das Stahlband geklebt wird und hierzu zweiseitige Klebebänder oder Kleber zur adhäsiven Verbindung der beiden Elemente zum Einsatz kommen. Linear measuring devices and systems are known and used in the prior art. It is a magnetic tape assembly made of a plastic bonded hard magnetic ferrite on a steel carrier tape, wherein the magnetic tape is glued to the steel strip and this two-sided adhesive tapes or adhesive for adhesive connection of the two elements are used.
AUFGABE DER ERFINDUNG OBJECT OF THE INVENTION
Aufgabe der Erfindung ist es eine Linear-Messvorrichtung für eine Sensoranordnung zur Verfügung zu stellen, welche schnell und kostengünstig hergestellt werden kann und dabei in der Anwendung eine längere Lebensdauer aufweist. The object of the invention is to provide a linear measuring device for a sensor arrangement, which can be produced quickly and inexpensively, while having a longer service life in the application.
LÖSUNG DER AUFGABE SOLUTION OF THE TASK
Zur Lösung der Aufgabe führen die Merkmale nach den Ansprüchen 1 bis 5. To achieve the object, the features according to claims 1 to 5.
Die erfindungsgemässe Linear-Messvorrichtung besteht in erster Linie aus einem Magnetelement in Form eines flexiblen Magnetbandes und einem Metall-Trägerelement in Form eines Trägerbandes aus Stahl. Es kommen hierbei auch andere metallene Werkstoffe in Betracht. Stahl ist in besonderer Weise geeignet. Stahl stellt die notwendige mechanische Stabilität zur Verfügung und bestimmt mit seinem Ausdehnungskoeffizienten die Ausdehnung der Linear-Messvorrichtung. Damit sind auf Stahl aufgebrachte lineare Magnetelemente bestens an die Verwendung in Maschinen aus Stahlkonstruktionen angepasst. The inventive linear measuring device consists primarily of a magnetic element in the form of a flexible magnetic tape and a metal support element in the form of a carrier tape made of steel. In this case, other metal materials come into consideration. Steel is suitable in a special way. Steel provides the necessary mechanical stability and determines the extent of the linear measuring device with its coefficient of expansion. Thus, linear magnetic elements applied to steel are optimally adapted for use in machines made of steel structures.
Ausserdem stellt ferromagnetischer Stahl den notwendigen magnetischen Rückschluss für ein Magnetsystem dar, welches aus den einzelnen Polen des Magnetelementes und eben des Metall-Trägerelementes aus Stahl gebildet wird. Dadurch sind höhere Feldstärken erreichbar, als mit dem blossen Magnetelement allein. In addition, ferromagnetic steel is the necessary magnetic return for a magnet system, which is formed from the individual poles of the magnetic element and just the metal support member made of steel. As a result, higher field strengths can be achieved than with the mere magnetic element alone.
Denkbar und üblich sind hier auch nicht rostende Legierungen für das Metall-Trägerelement. Diese nicht-rostenden Legierungen sind gerade bei feuchten Umgebungsparametern von Vorteil für eine Langlebigkeit der Linear-Messvorrichtung. Das Magnetelement besteht in erster Linie aus einem in Kunststoff gebundenen hartmagnetischen Ferrit. Hierbei ist es unbeachtlich welche Kunststoffe zum Einsatz kommen. Der Fachmann hat hier eine grosse Auswahl an Kunststoffen in Form von Elastomeren oder Duroplasten. Die Auswahl kann an die notwendigen Anforderungen angepasst werden. Conceivable and common here are not rusting alloys for the metal support element. These non-rusting alloys are particularly advantageous for a long life of the linear measuring device, especially in the case of moist ambient parameters. The magnetic element consists primarily of a hard magnetic ferrite bound in plastic. It is irrelevant which plastics are used. The expert has here a large selection of plastics in the form of elastomers or thermosets. The selection can be adapted to the necessary requirements.
In einem bevorzugten Ausführungsbeispiel ist das Magnetelement und das Metall-Trägerelement einstückig extrudiert. In einem anderen Ausführungsbeispiel ist wird zunächst das Metall-Trägerelement hergestellt und dann auf das Metall-Trägerelement das Magnetelement aufvulkanisiert. In a preferred embodiment, the magnetic element and the metal support element is extruded in one piece. In another exemplary embodiment, the metal carrier element is first produced and then the magnetic element is vulcanized onto the metal carrier element.
In einem weiteren Ausführungsbeispiel ist das Metall-Trägerelement durch das Magnetelement komplett umschlossen. Auf diese Weise kann ebenfalls der Schutz vor Rost gewährleistet werden. In a further embodiment, the metal carrier element is completely enclosed by the magnetic element. In this way, the protection against rust can also be ensured.
Es ist hierbei denkbar, dass das Metall-Trägerelement entweder vollständig durch das Magnetelement umschlossen wird. Es ist aber auch möglich, dass das Metall-Trägerelement nur teilweise mit dem Magnetelement bedeckt wird. Sollte das Metall-Trägerelement bspw. in Form eines Plattenstrangs ausgebildet sein, so kann bspw. die eine Seite der Platte vollständig oder teilweise mit dem Magnetelement vulkanisiert sein, wobei die andere Seite der Platte keinerlei Vulkanisierung aufweist. It is conceivable here that the metal carrier element is either completely enclosed by the magnetic element. But it is also possible that the metal carrier element is only partially covered with the magnetic element. If, for example, the metal carrier element is designed in the form of a plate strand, then one side of the plate can be completely or partially vulcanized with the magnetic element, the other side of the plate having no vulcanization.
Das Metall-Trägerelement kann bspw. aber auch in Form von Drähten oder Gitterrosten ausgebildet sein, welche dann ganz oder teilweise von dem Magnetelement umschlossen oder bedeckt sind. However, the metal carrier element may, for example, also be in the form of wires or gratings, which are then completely or partially enclosed or covered by the magnetic element.
Die beschriebene Sensoranordnung ist in der Regel ein Inkremental- und/oder Absolut-Mess-System. Dabei verfährt ein Messsystem in Form eines Sensors entlang eines Linear-Messmaßstabes und nimmt dabei die Magnetfelder des Magnetelementes auf und registriert die aufgenommenen Daten und berechnet hieraus die Position, Verfahrrichtung sowie relative Geschwindigkeit zwischen Messsystem und Linear-Messmaßstab.. The described sensor arrangement is usually an incremental and / or absolute measuring system. Here, a measuring system in the form of a sensor moves along a linear measuring scale and records the magnetic fields of the magnetic element and registers the recorded data and calculates the position, travel direction and relative speed between the measuring system and the linear measuring scale.
