Abstract

A marking system for electrical cables uses a coloured surface coding that is easily read. The insulating layer of the cable(10) has surface markings(11) formed by an impregnation of suitable particles that exhibit a characteristic similar to that of "cat's eyes"(RTM). Incident light is reflected off the markings in a range of the visible spectrum. The advantage of markings of this type is that reading is relatively independent of the ambient daylight condition. Additionally, the markings may be read when the cable surface is dirty.

Description

Vorrichtung zur Kennzeichnung von langgestrecktem GutDevice for marking elongated goods

Die Erfindung bezieht sich auf eine Vorrichtung zur Kennzeichnung von langgestrecktem Gut durch Farbstoffe, die entweder der Isolierung einer Ader oder des Kabelmantels beigefügt sind oder in Form von Zeichen auf bzw. in der Isolierung angebracht sind.The invention relates to a device for marking of elongated material by dyes, either of the insulation of a vein or the cable jacket or in the form of characters on or in the insulation are appropriate.

Bei langgestrecktem Gut, insbesondere bei elektrischen Kabeln oder Leitungen, ist es oft wichtig, irgendwelche Markierungen auf oder in. der Oberfläche des Gutes anzubringen, um damit Aussagen über nicht unmittelbar erkennbare Eigenschaften dieses Gutes machen zu können. Seit langem ist es bekannt, derartige Kennzeichnungen durch unterschiedliche Farben zu bewirken, die beispielsweise der gesamten Oberfläche oder nur einem Teil davon beigefügt werden oder die in Form farbiger Zeichen auf oder in der Oberfläche angebracht sind (DE-PS 427 957, DE-PS 729 563).In the case of elongated goods, especially electrical cables or Lines, it is often important to have any markings on or in the surface of the goods in order to make statements about properties that are not immediately recognizable to be able to do this good. Such markings have long been known by effecting different colors, for example the entire surface or only part of it, or in the form of colored characters or are attached in the surface (DE-PS 427 957, DE-PS 729 563).

Da die äußere Farbgebung meist nicht ausreicht, um die für den Anwender insbesondere elektrischer Kabel oder Leitungen notwendigen Daten (Typ, Hersteller, Normung, Querschnitt) erschöpfend auszusagen, werden solche Kabel oder Leitungen oftmals mit einem aufgedruckten oder geprägten Schriftzug versehen. In vielen Einsatzfällen ist dieser Schriftzug bereits nach kurzer Betriebsdauer aufgrund der Oberflächenverschmutzung kaum noch erkennbar, wenn die Oberfläche nicht zuvor umständlich gereinigt wird. Auch bei schlechten Lichtverhältnissen, insbesondere unter Tage, ist die bisherige Kennzeichnung vielfach nur schwer lesbar.Since the exterior color scheme is usually not enough for the user in particular electrical cables or lines necessary data (type, manufacturer, Standardization, cross-section) exhaustively state such cables or lines often provided with a printed or embossed lettering. In many cases this lettering is already after a short period of operation due to the surface contamination hardly noticeable if the surface is not carefully cleaned beforehand. Even in poor light conditions, especially underground, the previous one Markings are often difficult to read.

Der Erfindung liegt daher die Aufgabe zugrunde, die Erkennbarkeit farbiger Markierungen an oder in der Oberfläche von langgestrecktem Gut wesentlich zu verbessern.The invention is therefore based on the object of recognizability colored markings on or in the surface of elongated goods are essential to improve.

Diese Aufgabe wird gemäß der Erfindung dadurch gelöst, daß die verwendeten Farbstoffe bzw. deren Partikel reflektierende Eigenschaften aufweisen bzw. in bevorzugten Spektralbereichen Licht emittieren.This object is achieved according to the invention in that the used Dyes or their particles have reflective properties or are preferred Spectral ranges emit light.

Durch die Verwendung solcher Farbstoffe, deren Partikel beispielsweise entsprechend den bekannten "Katzenaugen" Licht in bevorzugte Richtungen reflektieren, oder die die Eigenschaft aufweisen, Licht in ganz schmalen Spektralbereichen zu emittieren, wie dies beispielsweise bei den sogenannten Tageslichtleuchtfarben der Fall ist, wird eine erhebliche Verstärkung der Erkennbarkeit derartiger farbiger Markierungen bewirkt. Durch die bevorzugte Reflexion des Lichtes in bestimmte Richtungen bzw. durch den Integrationseffekt bei der Lichtemission in schmalen Spektralbereichen wird eine so erhebliche Verstärkung der Erkennbarkeit erzielt, daß die geringen Teile der freien Oberfläche bzw. die geringe Menge des vorhandenen Lichtes auch bei stark verschmutzter Oberfläche bzw. bei besonders schlechter Beleuchtung, wie sie beispielsweise im Bergbau anzutreffen ist, ausreichen, um diese Zeichen erkennbar zu machen bzw. sichtbar werden zu lassen.By using such dyes, their particles, for example reflect light in preferred directions according to the well-known "cat's eyes", or which have the property of emitting light in very narrow spectral ranges emit, as is the case, for example, with the so-called daylight fluorescent colors of the If so, there is a considerable increase in the recognizability of such colored ones Causes markings. Due to the preferential reflection of the light in certain directions or by the integration effect in light emission in narrow spectral ranges so significant a reinforcement of the recognizability is achieved that the low Parts of the free surface or the small amount of available light, too if the surface is very dirty or if the lighting is particularly poor, such as it is found in mining, for example, suffice to display these characters recognizable to make or to make visible.

In der Zeichnung wird die Erfindung anhand eines Ausführungsbeispieles erläutert.In the drawing, the invention is illustrated using an exemplary embodiment explained.

In der einzigen Figur ist ein schematisch gehaltener Querschnitt eines Kabels wiedergegeben, von dem lediglich Einzelheiten der äußeren Isolierung dargestellt sind.In the single figure, a schematically held cross section is a Cable shown, of which only details of the external insulation are shown are.

Der aus Kunststoff bestehende, die Isolierung bildende Kabelmantel 10 besitzt an seiner Oberfläche Markierungen 11, denen spezielle Farbstoffe beigemischt sind. Die Farbpartikel besitzen entweder die Eigenschaft, einfallendes Licht nach Art der "Katzenaugen" bevorzugt in die Einfallsrichtung zu reflektieren bzw. einfallendes Licht verschiedener Spektralbereiche in Licht ganz bestimmter und eng begrenzter Spektralbereiche umzuwandeln und durch diesen Integrationseffekt die Leuchtwirkung der Farbstoffe zu erhöhen.The plastic cable sheath that forms the insulation 10 has markings 11 on its surface, to which special dyes are added are. The color particles either have the property of following incident light Type of "cat's eyes" preferably to reflect or incident in the direction of incidence Light of different spectral ranges in light very specific and narrowly limited To convert spectral ranges and through this integration effect the lighting effect to increase the dyes.
