Description
Die Erfindung betrifft eine Vorrichtung zur Detektion von Etiketten auf einem Trägermaterial.The The invention relates to a device for detecting labels on a carrier material.
Eine derartige Vorrichtung ist aus der DE-PS 195 21 129 bekannt. Diese Vorrichtung umfasst einen kapazitiven Sensor mit zwei Kondensatorelementen, die in Abstand nebeneinander liegend einer Kondensatorplatte gegenüberstehen. Das Trägermaterial mit den Etiketten wird im Luftspalt zwischen der Kondensatorplatte und den Kondensatorelementen geführt.A Such device is known from DE-PS 195 21 129. This Device comprises a capacitive sensor with two capacitor elements, which face each other at a distance from a capacitor plate. The carrier material with the labels is in the air gap between the capacitor plate and guided the capacitor elements.
Zur Detektion der Etiketten auf dem Trägermaterial ist jedem Kondensatorelement ein eine Pulsfolge erzeugendes Zeitglied und ein Tiefpass nachgeschaltet, wobei die Ausgänge der Tiefpässe auf die Eingänge eines Differenzverstärkers geführt sind.to Detection of the labels on the carrier material is every capacitor element a timing element generating a pulse sequence and a low pass connected downstream, being the outputs of low passes the entrances a differential amplifier are led.
Mit dieser Schaltungsanordnung sind Etiketten auf dem Trägermaterial detektierbar, und zwar selbst dann, wenn die Etiketten und das Trägermaterial aus transparenten Materialien bestehen.With this circuit arrangement are labels on the carrier material detectable, even if the labels and the carrier material consist of transparent materials.
Nachteilig hierbei ist jedoch, dass derartige Vorrichtungen äußerst empfindlich gegen Temperatureinflüsse und insbesondere gegen Feuchtigkeit sind. Desweiteren ist die Detektion von metallisierten Materialien problematisch.adversely here, however, is that such devices are extremely sensitive against temperature influences and especially against moisture. Furthermore, the detection of metallized materials problematic.
Zudem können mit den beiden Kondensatorelementen lediglich die Signalflanken erfasst werden, welche bei der Detektion einer Etikettenkante auftreten. Voraussetzung hierfür ist, dass die Etiketten mit dem Trägermaterial mit einer vorgegebenen Geschwindigkeit an den Kondensatorelementen vorbeibewegt werden. Eine statische Detektion bei ruhendem Trägermaterial ist nicht möglich. Zudem ist nachteilig, dass eine Etikettendetektion nur dann sicher möglich ist, wenn die Etikettenkanten längs einer Geraden quer zur Transportrichtung des Trägermaterials verlaufen, so dass über die Breite der Etiketten jeweils ein zumindest näherungsweise konstanter Abstand benachbarter Etiketten vorliegt.moreover can with the two capacitor elements only the signal edges recorded which occur when a label edge is detected. Prerequisite for this is that the labels with the carrier material with a given Speed can be moved past the capacitor elements. Static detection with the carrier material at rest is not possible. moreover is disadvantageous that label detection is only possible reliably, if the label edges are longitudinal a straight line running transversely to the transport direction of the carrier material, so that about the width of the labels in each case an at least approximately constant distance adjacent labels.

Das Feld des kapazitiven Sensors beeinflusst einen Oszillator, der frequenzmoduliert ist. Die Signaländerungen des Oszillators werden zunächst gefiltert, so dass kleine Signaländerungen eliminiert werden. Zur Detektion der Etiketten werden die verbleibenden großen Signaländerungen einer Spitzenwertgleichrichtung und einer Abtast- und Halteschaltung zugeführt. Über eine Triggerung und eine Schwellwerteinstellung werden die so verarbeiteten Signaländerungen in ein binäres, das Vorhandensein einer Etikette anzeigendes Signal umgesetzt.The The field of the capacitive sensor influences an oscillator that modulates frequency is. The signal changes of the oscillator are first filtered, so small signal changes be eliminated. The remaining ones are used to detect the labels huge signal changes a peak value rectification and a sample and hold circuit fed. Over a Triggering and a threshold value setting are the processed signal changes into a binary, signal indicating the presence of a label implemented.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung der eingangs genannten Art so auszubilden, dass eine sichere Detektion von Etiketten auf Trägermaterialien für ein möglichst breites Spektrum von Materialien gewährleistet ist.The The invention has for its object a device of the beginning mentioned type so that reliable detection of labels on support materials for a preferably wide range of materials is guaranteed.
Zur Lösung dieser Aufgabe sind die Merkmale des Anspruchs 1 vorgesehen. Vorteilhafte Ausführungsformen und zweckmäßige Weiterbildungen der Erfindung sind in den Unteransprüchen beschrieben.to solution this object, the features of claim 1 are provided. advantageous embodiments and appropriate further training the invention are described in the subclaims.
Mittels der Ultraschallwellen sind Etiketten auf dem Trägermaterial nahezu unabhängig von deren Materialbeschaffenheit detektierbar. Insbesondere können Etiketten auf Trägermaterialien erkannt werden, selbst wenn diese aus transparenten Materialien bestehen oder wenn diese metallisierte Oberflächen aufweisen. Zudem sind mit der erfindungsgemäßen Vorrichtung selbst sehr dünne Etiketten sicher detektierbar. Besonders vorteilhaft dabei ist, daß die erfindungsgemäße Vorrichtung unempfindlich gegen Umgebungseinflüsse, wie zum Beispiel Feuchtigkeit oder Temperaturschwankungen ist.through The ultrasound waves are almost independent of labels on the carrier material whose material properties are detectable. In particular, labels on substrates be recognized, even if they are made of transparent materials exist or if they have metallized surfaces. Also are with the device according to the invention even very thin ones Labels can be detected safely. It is particularly advantageous that the device according to the invention insensitive to environmental influences such as moisture or temperature fluctuations.
Weiterhin ist vorteilhaft, daß mit der erfindungsgemäßen Vorrichtung Etiketten auf dem Trägermaterial unabhängig davon erkannt werden können, ob das Trägermaterial relativ zur Vorrichtung bewegt wird oder nicht. Schließlich ist vorteilhaft, daß mit der erfindungsgemäßen Vorrichtung die gesamte Fläche der Etiketten erkannt wird und nicht nur deren Kanten. Dies führt dazu, daß Etiketten mit nahezu beliebigen Randkonturen erfaßbar sind.Farther it is advantageous that with the device according to the invention Labels on the backing independently can be recognized whether the backing material is moved relative to the device or not. Finally is advantageous that with the device according to the invention the entire area the label is recognized and not just its edges. This leads to, that labels can be detected with almost any edge contours.
