Abstract

This invention concerns a process and device for producing deactivatable anti-theft devices (1) for securing articles electronically. The anti-theft devices consist of a soft magnetic strip (2) of predetermined length which emits a characteristic signal when subjected to a magnetic alternating field and of segments (3) of a specific length of half-hard or hard magnetic material. The segments (3) are arranged relative to the soft magnetic strips so that they eliminate the characteristic signal from the soft magnetic strips (2) when in a saturated state. The aim of the invention is to present a process and a device which make it possible to economically produce deactivatable strip elements. As for the process, the aim is achieved by producing an endless strip (4) of medium-hard or hard magnetic material which is cut into individual segments (3) of a defined length, which segments are then advanced by a conveyor (7), the speed of which is greater than the speed at which the endless strip (4) is produced. Thus the relative velocity is adjusted to provide the desired distance between two consecutive segments (3) and so that a soft magnetic endless strip (15) is connected to the segments (3) of medium-hard or hard magnetic material which are separated from each other.

Description

Verfahren und Vorrichtung zur Herstellung von deaktivierbaren Sicherungselementen Method and device for producing deactivatable security elements
Die Erfindung betrifft ein Verfahren und eine Vorrichtung zur Herstellung von deaktivierbaren Sicherungselementen für die elektronische ArtikelSicherung, wobei ein Sicherungselement aus einem weichmagnetischen Streifen vorgegebener Länge, der bei Anlegen eines magnetischen Wechselfeldes zur Abgabe eines charakteristischen Signals angeregt wird, und Abschnitten definierter Länge eines halbhart- oder hartmagnetischen Materials besteht, wobei die Abschnitte bezüglich des weichmagnetischen Streifens derart angeordnet sind, daß sie im Sättigungszustand das charakteristische Signal des weichmagnetischen Streifens unterbinden.The invention relates to a method and a device for producing deactivatable security elements for electronic article security, wherein a security element made of a soft magnetic strip of a predetermined length, which is excited to emit a characteristic signal when an alternating magnetic field is applied, and sections of a defined length of a semi-hard or consists of hard magnetic material, the sections with respect to the soft magnetic strip being arranged in such a way that, when saturated, they prevent the characteristic signal of the soft magnetic strip.
In zunehmendem Maße werden die Waren in Kaufhäusern und Lagern elektronisch gegen Diebstahl gesichert . Eine Möglichkeit der elektronischen Diebstahlsicherung besteht darin, an den Waren Streifenelemente, also längliche, weichmagnetische Metallstücke (z.B. VITROVAC der Firma Vacuumschmelze) , anzubringen. Diese Streifenelemente lösen in entsprechenden Überwachungssystemen, die üblicherweise im Ausgangsbereich der gesicherten Einrichtung angeordnet sind, einen Alarm aus. Grob läßt sich die elektronische Artikelsicherung folgendermaßen beschreiben: Ein Überwachungssystem weist eine Sende- und eine Empfangsvorrichtung auf. Die Sendevorrichtung sendet ein Abfragesignal in eine Überwachungszone aus. Durch dieses Abfragesignal wird das Streifenelement zur Aussendung eines Antwortsignals angeregt, das von derThe goods in department stores and warehouses are increasingly being electronically secured against theft. One possibility of electronic theft protection is to attach strip elements, i.e. elongated, soft magnetic metal pieces (eg VITROVAC from Vacuumschmelze) to the goods. These strip elements trigger an alarm in corresponding monitoring systems, which are usually arranged in the exit area of the secured device. The electronic article surveillance can be roughly described as follows: A monitoring system has a transmitting and a receiving device. The transmitting device sends an interrogation signal into a monitoring zone. By means of this interrogation signal, the stripe element is excited to emit a response signal which is generated by the
Empfangsvorrichtung detektiert und identifiziert wird. Das Auftreten eines Antwortsignals wird nämlich mit dem unerlaubten Passieren eines elektronisch gesicherten Artikels durch die Abfragezone gleichgesetzt, und der Alarm wird ausgelöst. Ein Beispiel für ein entsprechendes Überwachungssystem ist in der EP 0 123 586 AI beschrieben.Receiving device is detected and identified. The occurrence of a response signal is in fact equated with the illegal passage of an electronically secured article through the interrogation zone, and the alarm is triggered. An example of a corresponding monitoring system is described in EP 0 123 586 AI.
Das Auslösen eines Alarms soll selbstverständlich nicht mehr stattfinden, sobald ein Kunde die Ware ordnungsgemäß erworben hat. Um dieser Anforderung zu genügen, sind die Streifenelemente deaktivierbar ausgebildet. Eine Deaktivierung wird dadurch erreicht, daß bezüglich des weichmagnetischen Streifens Abschnitte eines halbhart- oder hartmagnetischen Materials angeordnet sind, die eine Reaktion des Sicherungselementes auf das Abfragesignal hin unterbinden, sobald das halbhart- oder hartmagnetische Material durch Anlegen eines entsprechend hohen magnetischen Feldes in die Sättigung getrieben worden ist.An alarm should of course no longer be triggered once a customer has properly purchased the goods. In order to meet this requirement, the strip elements are designed to be deactivated. Deactivation is achieved in that, with respect to the soft magnetic strip, sections of a semi-hard or hard magnetic material are arranged which prevent a reaction of the securing element to the interrogation signal as soon as the semi-hard or hard magnetic material is driven into saturation by applying a correspondingly high magnetic field has been.
Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren und eine Vorrichtung vorzuschlagen, die es erlauben, die deaktivierbaren Streifenelemente kostengünstig zu fertigen.The invention is based on the object of proposing a method and a device which make it possible to produce the deactivatable strip elements at low cost.
Bezüglich des Verfahrens wird die Aufgabe dadurch gelöst, daß ein Endlosstreifen aus halbhart- oder hartmagnetischem Material bereitgestellt und in die einzelnen Abschnitte definierter Länge unterteilt wird, daß die Abschnitte definierter Länge mittels einer Fördervorrichtung weitergeleitet werden, deren Geschwindigkeit größer ist als die Geschwindigkeit, mit der der Endlosstreifen bereitgestellt wird, wobei die Relativgeschwindigkeit so bemessen ist, daß ein gewünschter Abstand zwischen zwei aufeinanderfolgenden Abschnitten erzielt wird, und daß ein weichmagnetischer Endlosstreifen mit den voneinander beabstandeten Abschnitten aus halbhart- oder hartmagnetischem Material verbunden wird. Eine wesentliche Verbesserung des erfindungsgemäßen Verfahrens besteht darin, daß es eine kontinuierliche Fertigung von deaktivierbaren Sicherungselementen ermöglicht .With regard to the method, the object is achieved in that an endless strip made of semi-hard or hard magnetic material is provided and divided into the individual sections of defined length, that the sections of defined length are passed on by means of a conveyor device whose speed is greater than the speed at which the endless strip is provided, the relative speed being so is dimensioned that a desired distance between two successive sections is achieved, and that a soft magnetic endless strip is connected to the spaced sections of semi-hard or hard magnetic material. A significant improvement of the method according to the invention is that it enables continuous production of security elements that can be deactivated.
Gemäß einer vorteilhaften Weiterbildung des erfindungsgemäßen Verfahrens ist vorgesehen, daß auf die voneinander beabstandeten Abschnitte aus halbhart- oder hart-magnetischem Material ein Verbundmaterial aufgetragen wird und daß der weichmagnetische Endlosstreifen auf die entgegengesetzte Seite der halbhart- oder hartmagnetischen Abschnitte aufgebracht wird. Möglich ist es selbstver-ständlich auch, daß der weichmagnetische Endlosstreifen direkt mit den Abschnitten aus halbhart- oder hart-magnetischem Material verbunden wird.According to an advantageous development of the method according to the invention, it is provided that a composite material is applied to the spaced apart sections of semi-hard or hard magnetic material and that the soft magnetic endless strip is applied to the opposite side of the semi-hard or hard magnetic sections. Of course, it is also possible for the soft magnetic endless strip to be connected directly to the sections made of semi-hard or hard magnetic material.
Eine Ausgestaltung hinsichtlich des erfindungsgemäßen Verfahrens schlägt vor, daß das erstellte Bandmaterial aufgewickelt wird. Gemäß einer alternativen Lösung wird das Bandmaterial mit den deaktivierbaren Sicherungsstreifen in einzelne die Sicherungselemente tragende Abschnitte unterteilt .An embodiment with regard to the method according to the invention suggests that the strip material produced is wound up. According to an alternative solution, the strip material with the deactivatable securing strips is divided into individual sections carrying the securing elements.
Die Aufgabe wird bezüglich der erfindungsgemäßen Vorrichtung dadurch gelöst, daß eine Vorratsrolle vorgesehen ist, von der ein halbhart- oder hartmagnetischer Endlosstreifen abgewickelt wird, daß eine Schneidestation vorgesehen ist, die den halbhart- oder hartmagnetischen Endlosstreifen in einzelne Abschnitte einer vorgegebenen Länge unterteilt, daß eine Fördervorrichtung vorgesehen ist, die eine höhere Geschwindigkeit aufweist, als die Geschwindigkeit, mit der der halbhart- oder hartmagnetische Endlosstreifen bereitgestellt wird, so daß die aufeinanderfolgenden Abschnitte aus halbhart- oder hartmagnetischem Material den gewünschten Abstand voneinander haben, und daß eine Vorratsrolle vorgesehen ist, von der ein weichmagnetische Endlosstreifen abgewickelt wird, der mit den halbhart- oder hartmagnetischen Abschnitten verbunden wird (Bandmaterial) .The object is achieved with respect to the device according to the invention in that a supply roll is provided, from which a semi-hard or hard magnetic endless strip is unwound, that a cutting station is provided which divides the semi-hard or hard magnetic endless strip into individual sections of a predetermined length that a Conveyor is provided which has a higher speed than the speed at which the semi-hard or hard magnetic endless strip is provided, so that the successive Sections of semi-hard or hard magnetic material have the desired distance from each other, and that a supply roll is provided, from which a soft magnetic endless strip is unwound, which is connected to the semi-hard or hard magnetic sections (tape material).
Gemäß einer kostengünstigen Weiterbildung der erfindungsgemäßen Vorrichtung handelt es sich bei der Fördervorrichtung um ein Förderband, bezüglich dessen eine Vakuumquelle derart angeordnet ist, daß die einzelnen Abschnitte aus halbhart- oder hartmagnetischem Material im gewünschten Abstand voneinander auf dem Förderband fixiert werden.According to an inexpensive development of the device according to the invention, the conveyor device is a conveyor belt, with respect to which a vacuum source is arranged such that the individual sections made of semi-hard or hard magnetic material are fixed on the conveyor belt at the desired distance from one another.
Da die bearbeiteten Materialien magnetisch sind, schlägt eine alternative Ausgestaltung vor, daß es sich bei der Fördervorrichtung um ein Förderband handelt, bezüglich dessen zumindest ein Magnet derart angeordnet ist, daß die einzelnen Abschnitte aus halbhart- oder hart-magnetischem Material im gewünschten Abstand voneinander auf dem Förderband fixiert werden .Since the processed materials are magnetic, an alternative embodiment suggests that the conveyor device is a conveyor belt, with respect to which at least one magnet is arranged in such a way that the individual sections of semi-hard or hard magnetic material open at the desired distance from one another fixed on the conveyor belt.
Als günstig hat es sich herausgestellt, wenn das fertige Bandmaterial, bestehend aus zusammenhängenden deaktivierbaren Streifenelementen, anschließend auf eine Speicher-rolle aufgewickelt wird.It has proven to be advantageous if the finished strip material, consisting of coherent strip elements that can be deactivated, is then wound onto a storage roll.
Die Erfindung wird anhand der nachfolgenden Figuren näher erläutert . Es zeigt :The invention is explained in more detail with reference to the following figures. It shows :

Fig. 1 zeigt einen Längsschnitt durch eine vorteilhafte Ausführungsform der erfindungsgemäßen Vorrichtung. Der Endlosstreifen 4 aus halbhart- oder hartmagnetischem Material wird von einer Vorratsrolle 5 abgewickelt und in der Schneidestation 6 in Abschnitte 3 einer gewünschten Länge unterteilt. Die Abschnitte 3 werden anschließend von dem Förderband der Fördervorrichtung 7 übernommen und weiter in Maschinenlaufrichtung transportiert. Im gezeigten Fall handelt es sich bei der Fördervorrichtung 7 um ein Förderband mit Luftlöchern. Bezüglich des Förderbandes ist eine Vakuumquelle 8 angeordnet, die die einzelnen Abschnitte 3 des halbhart- oder hartmagnetischen Materials auf einer gewünschten Position des laufenden Förderbandes fixiert. Da erfindungsgemäß das Förderband der Fördervor-richtung 13 eine größere Geschwindigkeit hat als die rotierenden Schneidezylinder der Schneidestation 6, haben die einzelnen Abschnitte 3 aus halbhart- oder hart-magnetischem Material auf dem Förderband einen gewissen Abstand zueinander. Der Abstand selbst ist über die Relativgeschwindigkeit zwischen Schneidestation 6 und Fördervorrichtung 13 beliebig einstellbar.Fig. 1 shows a longitudinal section through an advantageous embodiment of the device according to the invention. The endless strip 4 made of semi-hard or hard magnetic material is unwound from a supply roll 5 and divided into sections 3 of a desired length in the cutting station 6. The sections 3 are then taken over by the conveyor belt of the conveyor device 7 and transported further in the machine running direction. In the case shown, the conveyor device 7 is a conveyor belt with air holes. With regard to the conveyor belt, a vacuum source 8 is arranged, which fixes the individual sections 3 of the semi-hard or hard magnetic material at a desired position of the running conveyor belt. Since, according to the invention, the conveyor belt of the conveyor device 13 has a higher speed than the rotating cutting cylinders of the cutting station 6, the individual sections 3 made of semi-hard or hard magnetic material on the conveyor belt are at a certain distance from one another. The distance itself can be set as desired via the relative speed between the cutting station 6 and the conveyor device 13.
Im hinteren Bereich des Förderbandes wird auf die voneinander beabstandeten Abschnitte 3 ein Verbundmaterial 16 aufgeklebt. Die über das Verbundmaterial 16 miteinander verbundenen Abschnitte 3 werden anschließend in der Beschichtungs- oder Laminierstation 12 mit einem weichmagnetischen Endlosstreifen 15 verklebt. Der weichmagnetische Endlosstreifen 15 wird von der Vorratsrolle 11 abgewickelt. Das fertige Bandmaterial 13 wird dann auf die Speicherrolle 14 aufgewickelt .In the rear area of the conveyor belt, a composite material 16 is glued to the spaced-apart sections 3. The sections 3 connected to one another via the composite material 16 are then glued in the coating or laminating station 12 with a soft magnetic endless strip 15. The soft magnetic endless strip 15 is unwound from the supply roll 11. The finished strip material 13 is then wound onto the storage roll 14.
In Fig. 2 ist eine Draufsicht auf das fertige Bandmaterial 13 dargestellt . Das Bandmaterial 13 besteht aus einem weichmagnetischen Endlosstreifen 2, auf dem halbhart- oder hartmagnetische Abschnitte 3 in einem gewünschten Abstand voneinander angeordnet sind.
