Description

Verfahren zur Längungsmessung von bandförmigem Walzgut Zusatz zum Patent 945190 Gegenstand des Hauptpatents 945 190 ist ein Verfahren und Einrichtung zur Längungsmessung von bandförmigem Walzgut, bei dem am ungelängten und am gelängten Walzgut ein mit einer Magnetschicht versehenes endloses Band angeordnet ist, das unmittelbar durch das in Bewegung befindliche Walzgut angetrieben wird, wobei auf die Magnetschicht der Bänder synchron periodische Kennzeichen gegeben werden, die in den Kennzeichengebern zugeordneten Empfãngern Signalspannungen erzeugen, die zur Anzeige dienen. Die Materialges chwindigkeiten des ungelängtcn und des gelängten Materials sind nämlich entsprechend der Längung verschieden, und damit auch die Impulsfolgen der beiden Einrichtungen.Method for the elongation measurement of strip-shaped rolling stock Addition to Patent 945190 The main patent 945 190 relates to a method and device for the elongation measurement of strip-shaped rolled material, with the unelonged and the elongated Rolling stock is arranged an endless belt provided with a magnetic layer, which is driven directly by the rolling stock in motion, with on the magnetic layer of the tapes are given synchronous periodic characteristics that Generate signal voltages in the license plate generators assigned receivers that serve for display. The material speeds of the un-elongated and the elongated Materials are namely different according to the elongation, and thus also the Pulse trains of the two devices.

Zur Durchführung des Verfahrens werden zwei Einrichtungen benutzt, die im wesentlichen aus einem über Rollen geführten endlosen Band bestehen, wobei das Band direkt an das Walzgut angedrückt wird. Das endlose Band ist auf einer Seite mit einer magnetisierbaren Schicht versehen, und über der Schicht eines jeden Bandes sind ein Impulsgeber und ein Impulsabnehmer mit Abstand zueinander angeordnet. Außerdem werden für die nach einem derartigen Verfahren arbeitenden Einrichtungen Mittel zur Löschung der Bandaufzeichnung benötigt. Somit ergibt sich ein beträchtlicher Aufwand, der durch das verbesserte Verfahren erheblich reduziert wird. Two devices are used to carry out the procedure: which consist essentially of an endless belt guided over rollers, wherein the strip is pressed directly against the rolling stock. The endless ribbon is on one side provided with a magnetizable layer, and over the layer of each tape a pulse generator and a pulse pick-up are arranged at a distance from one another. aside from that will be for the after institutions operating in such a process Means needed to erase the tape record. Thus there is a considerable one Effort that is significantly reduced by the improved process.

Gemäß der Erfindung wird bei einem Verfahren zur Längungsmessung von bandförmigem Walzgut mittels von diesem angetriebener endloser Bänder vorgeschlagen, die Bänder mit Markierungen zu versehen, die photoelektrisch abgetastet werden, wobei die erzeugten elektrischen Impulse zur Anzeige der Längung dienen. According to the invention, in a method for measuring elongation proposed of strip-shaped rolled material by means of endless belts driven by this, to provide the tapes with markings that are photoelectrically scanned, the generated electrical impulses are used to indicate the elongation.

Die Einrichtung zur Durchführung des Verfahrens besteht wiederum aus zwei endlosen Bändern, die über Rollen geführt sind, wobei ein Band am ungelängten Walzgut angesetzt wird und das andere Band am gelängten Walzgut. Die Bänder besitzen nunmehr keine ~ magnetisierbare Schicht, sondern sind mit Markierungen versehen, die beispielsweise durch Aufdrucken von Mustern mit unterschiedlicher Farbtönung, durch Perforierung der Bänder od. dgl. hergestellt werden können. Vorteilhaft wird man die Markierungen auf beiden Bändern vollständig gleich ausbilden. Die umlaufenden Bänder werden in geeigneter Weise beleuchtet und durch je eine Photozelle abgetastet. Die von den Photozellen erzeugten elektrischen Impuls spannungen können zur Anzeige der Längung dann beliebigen Indikatoren zugeführt werden. The device for carrying out the method exists in turn from two endless belts, which are guided over rollers, with one belt at the unelonged Rolling stock is set and the other band on the elongated rolling stock. Own the tapes now no ~ magnetizable layer, but are provided with markings, which, for example, by printing patterns with different shades of color, by perforating the bands or the like. Can be produced. Becomes beneficial make the markings on both bands completely the same. The circulating Belts are illuminated in a suitable manner and each scanned by a photocell. The electrical impulse voltages generated by the photocells can be used for display purposes arbitrary indicators can then be fed to the elongation.
