Description

La présente invention concerne d'une manière générale les systèmes de sécurité contrôlant le déplacement d'objets et le transport illicite de ceux-ci à l'extérieur d'une enceinte, et plus particulièrement les dispositifs de marquage, par exemple sous forme d'étiquettes, des objets devant être surveillés.The present invention relates generally to security systems controlling the movement of objects and the illegal transport thereof outside an enclosure, and more particularly marking devices, for example in the form of labels, objects to be monitored.

La plupart des systèmes de sécurité mis en oeuvre à l'heure actuelle utilisent des dispositifs de marquage qui sont détectés au moment de leur passage dans des zones de contrôle. Ce type de système est couramment utilisé dans les magasins où les articles en vente sont munis d'étiquettes dont la présence est détectée lors du passage entre des antennes disposées le long des différents passages de sortie, y compris près des caisses.Most security systems implemented at present use marking devices which are detected when they pass through control zones. This type of system is commonly used in stores where the items for sale are provided with labels, the presence of which is detected during the passage between antennas arranged along the various exit passages, including near the cash desks.

Ces systèmes ne sont pas totalement infaillibles puisqu'il suffit de détacher l'étiquette de l'article avant de sortir du magasin pour que l'article dérobé ne soit pas détecté.These systems are not completely foolproof since it suffices to detach the label from the article before leaving the store so that the stolen article is not detected.

C'est pourquoi l'on voit apparaître des dispositifs de marquage de plus en plus volumineux et de plus en plus complexes à détacher de l'objet qui les porte sans moyen spécifique et sans risquer de détériorer l'objet ainsi marqué.This is why we see the appearance of increasingly voluminous and increasingly complex marking devices to detach from the object carrying them without specific means and without risking damaging the object thus marked.

Par ailleurs, ces dispositifs de marquage conservent leurs propriétés de faire détecter l'objet qui les porte tant qu'ils n'ont pas été enlevés ce qui les rend détectables même lors d'un passage licite dans des zones de contrôle, c'est-à-dire après les avoir régulièrement obtenus. Nombreux sont ceux qui, ayant acheté un objet dans un magasin, vont dans un autre magasin où l'objet est détecté lors de leur sortie et provoque l'arrivée précipitée des services de surveillance.Furthermore, these marking devices retain their properties of detecting the object carrying them as long as they have not been removed, which makes them detectable even during a lawful passage through control zones, that is that is, after regularly obtaining them. Many people, having bought an object in a store, go to another store where the object is detected when they leave and causes the precipitous arrival of the surveillance services.

Il existe donc un besoin en ce qui concerne des dispositifs de marquage non pas passifs et ne pouvant répondre qu'au moment d'une interrogation spécifique, par exemple lors d'un passage entre des antennes de la zone de contrôle, mais actifs c'est-à-dire capables de faire savoir qu'ils sont détachés ou détruits, et destructibles lorsque leur rôle est achevé, c'est-à-dire lorsque l'objet a été régulièrement acheté.There is therefore a need for marking devices which are not passive and which can only respond at the time of a specific interrogation, for example when passing between antennas in the control area, but active c ' that is to say capable of making known that they are detached or destroyed, and destructible when their role is completed, that is to say when the object has been regularly purchased.

Il a été proposé dans le US 3 713 133 délivré à Robert L. Nathans un dispositif de marquage accroché à l'article par une épingle de nourrice qui, d'une part, peut être détecté par des dispositifs de surveillance lors de son passage dans une zone contrôlée de sortie et dont, d'autre part, l'ouverture en vue de son retrait de l'article est détectée par des moyens de surveillance disposés dans le magasin.It was proposed in US 3,713,133 issued to Robert L. Nathans a marking device hung on the article by a safety pin which, on the one hand, can be detected by monitoring devices during its passage in a controlled exit zone, the opening of which, for its removal from the article, is detected by monitoring means arranged in the store.

Ces dispositifs de marquage permettent une surveillance plus efficace puisqu'une alarme retentit dès qu'une personne non habilitée ouvre l'épingle de nourrice mais sont encore défaillants lorsque la personne désirant subtiliser l'objet est prête à le détériorer en partie, par exemple lorsqu'il s'agit d'un habit en pratiquant une fente permettant de retirer l'épingle sans l'ouvrir.These marking devices allow more effective monitoring since an alarm sounds as soon as an unauthorized person opens the safety pin but are still faulty when the person wishing to steal the object is ready to partially deteriorate it, for example when '' it is a garment by making a slot allowing the pin to be removed without opening it.

La présente invention tend à proposer un dispositif de marquage tel qu'il ne puisse être désassemblé de l'article sur lequel il a été placé sans émettre de signal d'alarme.The present invention aims to propose a marking device such that it cannot be disassembled from the article on which it has been placed without emitting an alarm signal.

A cet effet, les dispositifs de marquage suivant l'invention comportent un anneau de détection dont une caractéristique électrique est modifiée lorsque l'on tente de désolidariser le dispositif de l'objet qui le porte.To this end, the marking devices according to the invention comprise a detection ring, an electrical characteristic of which is modified when an attempt is made to separate the device from the object which carries it.

Avantageusement, les dispositifs de marquage selon l'invention permettent également la gestion des objets portant lesdits dispositifs.Advantageously, the marking devices according to the invention also allow the management of objects carrying said devices.

Dans la première variante de réalisation représentée à la figure 1 le dispositif de marquage comporte un module électronique 13 et un anneau de détection 15 d'une tentative de fraude.In the first alternative embodiment shown in FIG. 1, the marking device comprises an electronic module 13 and a ring 15 for detecting an attempted fraud.

Le module électronique est de toute forme appropriée aux commandes que l'on veut lui faire réaliser, il pourra comporter une ou plusieurs puces électroniques, et/ou des composants de surface.The electronic module is of any form suitable for the commands that it is desired to make it perform, it may include one or more electronic chips, and / or surface components.

Le conducteur 15 formant l'anneau de détection est un conducteur très fin pouvant facilement se rompre. Ce conducteur peut être de surface importante, mais d'épaisseur très faible afin qu'il soit déchirable.The conductor 15 forming the detection ring is a very thin conductor which can easily break. This conductor can be large in area, but very thin so that it can be torn.

Ce conducteur 15 permet également d'assurer l'alimentation du module électronique 13 en énergie électrique en soumettant le dispositif de marquage à un champ énergétique, de préférence un champ radio-électrique. Un tel champ créé dans la zone à surveiller induit dans le conducteur 15 un courant qui est redressé de manière connue en soi pour alimenter ledit module électronique.This conductor 15 also makes it possible to supply the electronic module 13 with electrical energy by subjecting the marking device to an energy field, preferably a radio-electric field. Such a field created in the area to be monitored induces in the conductor 15 a current which is rectified in a manner known per se to supply said electronic module.

Les dispositifs de marquage sont particulièrement mais non exclusivement destinés au marquage en vue de leur surveillance d'articles tels que des articles mis en vente exposés dans des magasins. Ils peuvent également être mis en oeuvre dans des musées ou autres lieux d'exposition.The marking devices are particularly but not exclusively intended for marking with a view to their surveillance of articles such as articles put up for sale displayed in stores. They can also be used in museums or other exhibition places.

Les zones à surveiller étant ainsi généralement des locaux fermés, il est très aisé d'y créer des champs radio-électriques assurant l'apport d'énergie aux dispositifs de marquage selon l'invention.Since the areas to be monitored are generally closed premises, it is very easy to create radio fields there ensuring the supply of energy to the marking devices according to the invention.

Dans le cas des magasins tels que les grandes surfaces, ou des lieux d'exposition, le champ créé par la multitude de dispositifs d'éclairage que l'on y trouve, peut suffire à alimenter les dispositifs de marquage selon l'invention et permettre de s'affranchir de la nécessité de produire spécialement des champs énergétiques en vue de l'alimentation desdits dispositifs de marquage.In the case of stores such as supermarkets, or exhibition spaces, the field created by the multitude of lighting devices found there, may be sufficient to supply the marking devices according to the invention and allow to overcome the need to specially produce energy fields for the supply of said marking devices.

En choisissant et en programmant convenablement le module électronique porté par le dispositif de marquage selon l'invention, l'on peut également faire dialoguer ledit dispositif avec un réseau de contrôle des stocks et/ou des prix. A cet effet, l'on met en oeuvre un module électronique capable de stocker des informations et d'émettre et/ou de recevoir des informations soit seul, soit par l'intermédiaire d'une antenne.By choosing and programming the electronic module suitably carried by the marking device according to the invention, it is also possible to have said device communicate with a network for controlling stocks and / or prices. To this end, an electronic module capable of storing information and of transmitting and / or receiving information is implemented either alone or through an antenna.

Dans cette forme de réalisation, l'anneau de détection 15 est utilisé comme antenne.In this embodiment, the detection ring 15 is used as an antenna.

Les signaux numériques émis par le module électronique peuvent également être codés afin de les distinguer aisément d'autres signaux parasites extérieurs.The digital signals emitted by the electronic module can also be coded in order to easily distinguish them from other external parasitic signals.

Le dispositif de marquage selon l'invention est destiné à être mis en oeuvre dans des locaux possédant des systèmes de surveillance du type usuellement mis en oeuvre dans les zones de contrôle de sortie, ainsi que des systèmes de surveillance destinés à repérer des tentatives de fraude dans le local même.The marking device according to the invention is intended to be implemented in premises having surveillance systems of the type usually implemented in exit control zones, as well as surveillance systems intended to identify attempted fraud in the room itself.

Ces tentatives de fraude sont constituées par le fait que l'on cherche à désolidariser le dispositif de marquage de l'objet qui le porte.These fraud attempts are constituted by the fact that one seeks to separate the marking device from the object which carries it.

Suivant l'invention, le circuit électronique porté par l'étiquette assure l'émission d'un signal dès qu'une personne non autorisée tente de désolidariser l'étiquette de l'objet qui la porte.According to the invention, the electronic circuit carried by the label ensures the emission of a signal as soon as an unauthorized person attempts to separate the label from the object which carries it.

La détection de cette tentative de désolidarisation du dispositif de marquage est réalisée grâce à l'anneau de détection 15 et c'est à cet effet que le conducteur utilisé pour sa réalisation est de section très faible afin de le fragiliser, et de permettre que sa continuité électrique soit rompue dès que l'on tente de désolidariser le dispositif de marquage de l'article qui le porte.The detection of this attempt to separate the marking device is carried out using the detection ring 15 and it is for this purpose that the conductor used for its production is of very small section in order to weaken it, and to allow its electrical continuity is broken as soon as an attempt is made to separate the marking device from the article carrying it.

Dans une variante de réalisation, le dispositif de marquage est réalisé sous la forme d'une étiquette adhésive destinée à être collée sur un article mis en vente ou en exposition.In an alternative embodiment, the marking device is produced in the form of an adhesive label intended to be affixed to an article offered for sale or on display.

Le dispositif de marquage étant collé par toute sa surface sur l'article à protéger, il n'est pas envisageable de découper l'article pour enlever ledit dispositif afin de pouvoir subtiliser l'article ainsi démarqué car celui-ci serait trop détérioré pour être encore utilisable.The marking device being glued by its entire surface to the article to be protected, it is not possible to cut the article to remove said device in order to be able to steal the article thus demarcated because it would be too damaged to still usable.

La seule manière de se procurer l'article sans risquer que celui-ci soit détecté dans les zones de contrôle est alors de décoller ladite étiquette.The only way to obtain the article without risking that it will be detected in the control zones is then to peel off the said label.

Or pour ce faire, il est nécessaire de déformer ladite étiquette et de tirer sur celle-ci ce qui entraîne la coupure en un ou plusieurs points de l'anneau de détection 15.However, to do this, it is necessary to deform the said label and to pull on it, which causes the detection ring 15 to be cut at one or more points.

Cette coupure de la continuité électrique de l'anneau de détection 15 est immédiatement décelée par le module électronique, ce qui l'amène à envoyer un signal qui est intercepté et interprété par les moyens de surveillance répartis dans le local.This interruption of the electrical continuity of the detection ring 15 is immediately detected by the electronic module, which causes it to send a signal which is intercepted and interpreted by the monitoring means distributed in the room.

Le fil conducteur formant l'anneau de détection 15 peut être utilisé comme antenne d'émission de ce signal.The conducting wire forming the detection ring 15 can be used as the antenna for transmitting this signal.

Le service de surveillance est ainsi, grâce à l'étiquette selon l'invention, immédiatement prévenu de la tentative de fraude.The surveillance service is thus, thanks to the label according to the invention, immediately warned of the attempted fraud.

Une fois le signal de tentative de fraude émis, le dispositif de marquage suivant cette variante de réalisation ne peut plus recevoir d'alimentation ce qui le rend muet dans le local.Once the attempted fraud signal has been sent, the marking device according to this alternative embodiment can no longer receive power, which makes it mute in the room.

L'on peut toutefois prévoir que le module électronique reste fixé à l'article après l'arrachage de l'étiquette et soit détectable par les systèmes de surveillance disposés dans les zones de sortie du magasin pour fournir une seconde possibilité d'intercepter le fraudeur croyant s'être débarrassé des moyens de marquage de l'article.One can however foresee that the electronic module remains fixed to the article after the peeling of the label and is detectable by the surveillance systems arranged in the exit areas of the store to provide a second possibility of intercepting the fraudster believing to have got rid of the means of marking the article.

A cet effet, l'étiquette peut être réalisée en plusieurs couches pelables de manière à ce que l'anneau de détection 15 soit porté par une face externe de l'étiquette, il est ainsi d'une part très facilement rompu, et d'autre part enlevé de l'article portant le dispositif de marquage, tandis que le module électronique est solidarisé à l'adhésif et reste collé à l'article.For this purpose, the label can be produced in several peelable layers so that the detection ring 15 is carried by an external face of the label, it is thus on the one hand very easily broken, and on the other hand removed from the article carrying the marking device, while the electronic module is secured to the adhesive and remains glued to the article.

A titre d'exemple, l'on a représenté aux figures 2a à 2e les étapes de fabrication d'un dispositif de ce type.By way of example, FIGS. 2a to 2e show the steps for manufacturing a device of this type.

Lors de la première étape représentée à la figure 2a, l'on découpe dans un ruban de matière 1 un premier flan 2 ayant globalement la forme de l'étiquette à réaliser, mais étant de préférence de dimensions inférieures.During the first step shown in FIG. 2a, a first blank 2 having overall the shape of the label to be produced, but preferably having smaller dimensions, is cut from a ribbon of material 1.

Comme représenté à la figure 2b, l'un des coins dudit flan présente une découpe en L 5. Sur ce premier flan 2 l'on forme des portions métallisées conductrices 3, par exemple circulaires, disposées à proximité de la périphérie et l'on fixe un module électronique 5 sur le bord concave de la découpe.As shown in FIG. 2b, one of the corners of said blank has an L-shaped cutout 5. On this first blank 2 we form conductive metallized portions 3, for example circular, arranged close to the periphery and we fixes an electronic module 5 on the concave edge of the cutout.

Un second flan 6 est également découpé à partir du ruban de matière à l'étape représentée à la figure 2c.A second blank 6 is also cut from the ribbon of material in the step shown in FIG. 2c.

Ce second flan 6 présente une découpe 8 dans le coin correspondant à celui dans lequel a été disposé le module électronique sur le premier flan 2, ainsi que des ouvertures 7 disposées de manière à être en regard des portions métallisées lorsque l'on dispose les deux flans 2 et 6 l'un sur l'autre comme représenté à la figure 2d.This second blank 6 has a cutout 8 in the corner corresponding to that in which the electronic module has been placed on the first blank 2, as well as openings 7 arranged so as to be opposite the metallized portions when the two are placed blanks 2 and 6 one on the other as shown in Figure 2d.

Après avoir positionné les deux flans l'un sur l'autre avec les ouvertures 7 en regard des portions métallisées 3 et les avoir solidarisé par une couche adhésive, l'on forme l'anneau de détection 9 en positionnant sur le second flan 6 disposé sur le premier flan 2 des pistes conductrices que l'on raccorde aux portions métallisées 3 dudit premier flan 2.After positioning the two blanks one on the other with the openings 7 opposite the metallized portions 3 and having secured them by an adhesive layer, the detection ring 9 is formed by positioning on the second blank 6 disposed on the first blank 2 of the conductive tracks which are connected to the metallized portions 3 of said first blank 2.

L'on surmoule ensuite le module électronique dans un pion 101, puis l'on dispose au verso de l'étiquette une couche adhésive recouverte d'une feuille protectrice.The electronic module is then overmolded in a pin 101, then there is an adhesive layer covered with a protective sheet on the back of the label.

Lesdits flans 2 et 6 sont fixés l'un à l'autre par un adhésif ayant une force d'adhésion inférieure à celle de l'adhésif utilisé au verso de l'étiquette.Said blanks 2 and 6 are fixed to each other by an adhesive having an adhesion strength lower than that of the adhesive used on the back of the label.

Ainsi, lorsque l'étiquette 100 ainsi réalisée est collée sur un objet et que l'on tente de l'en enlever, l'on désolidarise le flan 6 disposé sur le dessus tandis que le flan 2 reste collé sur l'objet et l'on détruit la continuité de l'anneau de détection.Thus, when the label 100 thus produced is affixed to an object and an attempt is made to remove it, the blank 6 disposed on the top is detached, while the blank 2 remains stuck on the object and the 'The continuity of the detection ring is destroyed.

Dans cette forme de réalisation, l'on peut prévoir de marquer sur le flan 6 les données utiles telles que le prix, le code-barre, tandis que l'on réalise sur le flan inférieur 2 des impressions de décoration. L'acheteur de l'article peut alors décoller le flan supérieur 6 et laisser le flan inférieur 2 sur l'article afin de conserver les décorations.In this embodiment, provision can be made to mark on the blank 6 the useful data such as the price, the bar code, while decoration prints are made on the lower blank 2. The purchaser of the article can then take off the upper blank 6 and leave the lower blank 2 on the article in order to keep the decorations.

Le dispositif de marquage selon l'invention permet bien entendu à un client bien intentionné, ne cherchant pas à décoller l'étiquette, d'observer l'objet, de l'essayer s'il s'agit d'un vêtement, de le reposer, sans que le système de surveillance soit alerté.The marking device according to the invention of course allows a well-intentioned customer, not seeking to peel off the label, to observe the object, to try it if it is a garment, to rest, without the surveillance system being alerted.

Lors d'un passage licite de l'article portant une étiquette selon l'invention à une caisse du magasin, un signal électrique codé est induit dans le circuit électronique à travers l'anneau de détection fonctionnant alors à la manière d'une antenne. Ce signal est conçu de puissance suffisante pour assurer la destruction par vaporisation d'un fusible. Ce fusible est un fusible intégré de manière connue et usuelle dans le module électronique. Ce signal de destruction peut être émis au moment de la lecture du code barre porté par l'étiquette pour définir l'objet et son prix.During a lawful passage of the article bearing a label according to the invention to a store cash register, a coded electrical signal is induced in the electronic circuit through the detection ring then operating in the manner of an antenna. This signal is designed with sufficient power to ensure destruction by vaporization of a fuse. This fuse is a fuse integrated in a known and usual manner in the electronic module. This destruction signal can be emitted at the time of reading the bar code carried by the label to define the object and its price.

Grâce à la mise en oeuvre d'un module électronique, l'on peut prévoir de contrôler la destruction effective du fusible avnt de valider l'enregistrement du prix ce qui permet de s'assurer que la désactivation du dispositif de marquage selon l'invention est bien réalisée.Thanks to the implementation of an electronic module, it is possible to plan to control the actual destruction of the fuse before validating the recording of the price, which makes it possible to ensure that the deactivation of the marking device according to the invention is indeed carried out.

Ainsi, l'étiquette selon l'invention est rendue inopérante après que l'article a été licitement sorti du magasin ce qui le rend indétectable par d'autres systèmes de surveillance à travers lesquels l'objet pourra être transporté après son paiement.Thus, the label according to the invention is rendered inoperative after the article has been lawfully removed from the store, which makes it undetectable by other surveillance systems through which the object can be transported after payment.

La réserve d'énergie d'une telle étiquette peut être augmentée par la mise en oeuvre d'un condensateur dans le circuit électronique, un tel condensateur étant de préférence obtenu par impression directe ou superposition de couches conductrices.The energy reserve of such a label can be increased by the use of a capacitor in the electronic circuit, such a capacitor preferably being obtained by direct printing or superposition of conductive layers.

D'autres moyens de fragilisation tels que des lignes de fragilisation peuvent enfin être prévues dans l'étiquette de manière à aider la survenue des coupures en provoquant un déchirement de l'étiquette en plusieurs parties ce qui entraîne de manière sûre et incontournable la rupture de l'anneau de détection 15.Other means of embrittlement such as embrittlement lines may finally be provided in the label so as to help the occurrence of cuts by causing the label to be torn in several parts, which leads in a sure and unavoidable manner to the breaking of the detection ring 15.

Bien entendu, la description ci-dessus n'est donnée qu'à titre d'exemple, l'étiquette selon l'invention peut être utilisée pour de nombreuses autres applications telles que l'identification de personnes ou d'objets à leur passage devant des balises, la gestion de colis plus ou moins volumineux comme des paquets dans les services postaux, des bagages dans des aéroports, des bacs de déchets dans les centrales de traitement ...Of course, the above description is given only by way of example, the label according to the invention can be used for many other applications such as the identification of people or objects as they pass by. tags, management of more or less bulky parcels such as packages in postal services, luggage in airports, waste bins in central processing ...

Les étiquettes selon l'invention permettraient alors à la fois l'identification des personnes ou choses, la détection de toute tentative de fraude, telle que le transfert d'une étiquette d'une personne autorisée à une personne non autorisée, l'arrachage d'étiquette afin de détourner des colis, et pourraient être rendues inopérantes lors de la sortie de la personne ou de l'objet porteur de l'étiquette à la sortie de la zone surveillée.The labels according to the invention would then allow both the identification of persons or things, the detection of any attempted fraud, such as the transfer of a label from an authorized person to an unauthorized person, the removal of 'label to divert packages, and could be rendered inoperative when the person or object carrying the label leaves the exit from the monitored area.

Le module électronique peut être pourvu d'une mémoire permettant le stockage de toute donnée utile et d'un microprocesseur pour le traitement de ces données en liaison avec des moyens externes. Les dispositifs de marquage selon l'invention peuvent ainsi être utilisés pour effectuer des tris de colis.The electronic module can be provided with a memory allowing the storage of any useful data and with a microprocessor for the processing of these data in connection with external means. The marking devices according to the invention can thus be used to carry out sorting of packages.

En variante, pour des besoins spécifiques, il est également envisageable de prévoir des contacts externes sur l'étiquette afin de lui conférer d'autres possibilités de dialogue avec des lecteurs adéquats à la manière des cartes à puces.Alternatively, for specific needs, it is also conceivable to provide external contacts on the label in order to give it other possibilities of dialogue with suitable readers in the manner of smart cards.

Dans la variante de réalisation représentée à la figure 3, le dispositif de marquage selon l'invention comporte, en plus de l'anneau de détection 15, une antenne émettrice/réceptrice 14.In the variant embodiment shown in FIG. 3, the marking device according to the invention comprises, in addition to the detection ring 15, a transmitting / receiving antenna 14.

Cette forme de réalisation permet de continuer à assurer l'alimentation électrique du module électronique même après la coupure de l'anneau de détection 15, tant que ladite antenne n'est pas détruite.This embodiment makes it possible to continue to ensure the electrical supply of the electronic module even after the detection ring 15 has been cut off, as long as said antenna is not destroyed.

Il est alors possible de continuer à dialoguer avec ledit module électronique après la détection de la tentative de fraude, par exemple pour identifier l'article et/ou pour effectuer sa recherche dans la zone surveillée.It is then possible to continue to dialogue with said electronic module after the detection of the attempted fraud, for example to identify the article and / or to carry out its search in the monitored area.

Les figures 4a à 4f montrent à titre d'exemple non limitatif, un mode de fabrication de dispositifs de marquage selon la variante de la figure 3 se présentant sous forme d'étiquettes adhésives destinées à être collées sur des objets de toute nature.Figures 4a to 4f show by way of nonlimiting example, a method of manufacturing marking devices according to the variant of Figure 3 in the form of adhesive labels intended to be affixed to objects of all kinds.

Cette fabrication est faite en plusieurs étapes.This manufacturing is done in several stages.

Lesdites étiquettes sont, dans l'exemple représenté, réalisées à partir d'un ruban de matériau support tel que du polystyrène, du chlorure de polyvinyle ou de l'ABS. Ce ruban peut être préalablement obtenu par tout dispositif de fabrication connu tel que laminage, coulage, extrusion, ou injection ... D'autres matériaux peuvent bien entendu être utilisés pour constituer ledit ruban tels qu'un polyamide.Said labels are, in the example shown, made from a tape of support material such as polystyrene, polyvinyl chloride or ABS. This ribbon can be obtained beforehand by any device for known manufacture such as rolling, casting, extrusion, or injection ... Other materials can of course be used to form said tape such as a polyamide.

Ce ruban peut être préalablement décoré sur sa face destinée à être le recto de l'étiquette. L'on a noté par des lignes interrompues 10 sur le dessin l'emplacement des étiquettes que l'on fabrique.This ribbon can be previously decorated on its face intended to be the front of the label. The location of the labels produced is noted by broken lines 10 in the drawing.

Au cours d'une première étape de fabrication, des découpes de forme et de nature différentes sont effectuées dans le ruban 1 en des emplacements convenablement choisis.During a first manufacturing step, cuts of different shape and nature are made in the tape 1 at suitably chosen locations.

Dans la forme de réalisation choisie, deux tels groupes de découpes sont prévus.In the embodiment chosen, two such groups of cutouts are provided.

Les découpes du premier groupe représentées par les lignes 11 sont destinées à réaliser des zones de fragilisation de l'étiquette. Ces découpes seront par exemple, réalisées sous forme d'une succession de points à la manière des découpes usuellement faites dans les papiers destinés à l'informatique, ce qui permettra d'obtenir des étiquettes fragilisées mais restant aisément manipulables au cours de leur fabrication et de leur utilisation (mise en place sur les objets).The cuts of the first group represented by the lines 11 are intended to produce areas of weakness of the label. These cuts will, for example, be made in the form of a succession of dots in the manner of the cuts usually made in paper intended for data processing, which will make it possible to obtain labels which are weakened but which remain easy to handle during their manufacture and of their use (placement on objects).

Une seconde découpe 12 consiste dans l'enlèvement d'une surface de matière globalement en forme de L.A second cut 12 consists in the removal of a generally L-shaped surface of material.

Au cours de la seconde étape, l'on fixe sur le ruban 1 un module électronique 13 ainsi que des conducteurs 14 et 15 respectivement destinés à former une antenne réceptrice/émettrice et un anneau de détection. Lesdits conducteurs 14 et 15 sont reliés au module électronique par soudure, puis ledit module et les soudures sont de préférence recouverts d'un vernis protecteur.During the second step, an electronic module 13 is fixed on the ribbon 1 as well as conductors 14 and 15 respectively intended to form a receiving / transmitting antenna and a detection ring. Said conductors 14 and 15 are connected to the electronic module by welding, then said module and the solders are preferably covered with a protective varnish.

Comme représenté à la figure 4c, le module électronique 13 est disposé dans la zone du ruban 1 bordée par la partie concave de la découpe 12.As shown in FIG. 4c, the electronic module 13 is placed in the region of the ribbon 1 bordered by the concave part of the blank 12.

Ces éléments sont disposés sur la face du ruban destinée à former le verso de l'étiquette.These elements are arranged on the face of the ribbon intended to form the back of the label.

En variante, il est possible d'effectuer le circuit électronique comportant lesdits conducteurs et ledit module de manière séparée, par exemple sur un film polyamide que l'on fixe sur le ruban 1 par laminage. L'on prendra alors soin de fragiliser ledit film polyamide autour de l'anneau de détection afin de ne pas rendre inutiles les découpes de fragilisation 11 préalablement effectuées.As a variant, it is possible to carry out the electronic circuit comprising said conductors and said module separately, for example on a polyamide film which is fixed to the strip 1 by rolling. Care will then be taken to weaken said polyamide film around the detection ring so as not to make the weakening cuts 11 previously made unnecessary.

A l'étape représentée par le figure 4d, la zone du ruban portant le module électronique 13 est déformée afin d'éloigner ledit module du reste de la surface du ruban. L'on crée ainsi un décrochement dans la partie concave duquel est disposé le module électronique.In the step represented by FIG. 4d, the region of the ribbon carrying the electronic module 13 is deformed in order to move said module away from the rest of the surface of the ribbon. This creates a recess in the concave part of which is placed the electronic module.

Le ruban 1 portant le circuit électronique est alors disposé dans un moule non représenté au dessin afin d'enfermer ledit module électronique dans un pion 18 de protection. Dans le même temps, les conducteurs 14 et 15 sont laminés dans le matériau formant le ruban 1.The ribbon 1 carrying the electronic circuit is then placed in a mold not shown in the drawing in order to enclose said electronic module in a protective pin 18. At the same time, the conductors 14 and 15 are laminated in the material forming the ribbon 1.

Au cours de cette étape de surmoulage, la face supérieure du ruban peut être décorée si elle ne l'avait pas été précédemment.During this overmolding step, the upper face of the ribbon can be decorated if it had not been previously.

L'étape de fabrication suivante consiste dans la mise en place sur le verso de l'étiquette d'un film adhésif 16 protégé par une pellicule de protection 17 et à la découpe du ruban de matière 1 suivant les lignes 10. De manière connue en soi, seul le ruban est découpé tandis que le pellicule de protection est conservée intacte.The next manufacturing step consists in placing on the back of the label an adhesive film 16 protected by a protective film 17 and in cutting the ribbon of material 1 along the lines 10. In a manner known in only the ribbon is cut while the protective film is kept intact.

Enfin, à l'étape représentée à la figure 4f, le ruban 1 portant les étiquettes 21 terminées est enroulé avec interposition éventuelle d'un intercalaire permettant d'absorber la différence d'épaisseur entre le pion 18 et le reste de l'étiquette.Finally, in the step shown in FIG. 4f, the ribbon 1 carrying the finished labels 21 is wound with possible interposition of an interlayer making it possible to absorb the difference in thickness between the pin 18 and the rest of the label.

Ce ruban pourra alors être utilisé dans les machines à coller de type connu.This tape can then be used in gluing machines of known type.

L'on pourrait bien entendu fabriquer les étiquettes suivant un autre procédé, par exemple en reprenant le procédé décrit aux figures 2a à 2e et en ajoutant l'antenne.One could of course manufacture the labels according to another method, for example by repeating the method described in FIGS. 2a to 2e and adding the antenna.

L'utilisation d'un ruban de matière est bien entendu décrite à titre d'exemple, les étiquettes pouvant être obtenues à partir d'un support de toute autre forme telle qu'une plaque dans laquelle seraient découpées les étiquettes en une succession de colonnes.The use of a ribbon of material is of course described by way of example, the labels being obtainable from a support of any other shape such as a plate from which the labels would be cut out in a succession of columns. .

Comme on peut le voir sur la figure 4c, l'anneau de détection 15 est disposé sur la périphérie de l'étiquette afin qu'il soit détruit avant que l'antenne 14 risque de l'être. De plus, les lignes de fragilisation 11 sont disposées de manière telle qu'elles ne traversent pas l'antenne 14 afin de limiter les risques de détérioration de celle-ci.As can be seen in FIG. 4c, the detection ring 15 is placed on the periphery of the label so that it is destroyed before the antenna 14 risks being destroyed. In addition, the weakening lines 11 are arranged in such a way that they do not pass through the antenna 14 in order to limit the risks of deterioration of the latter.

En variante, l'on dispose l'anneau de détection 15 en forme de huit de manière à le rendre insensible aux émissions parasites pouvant être présentes dans les locaux renfermant les objets à surveiller. Il est possible de disposer de manière connue en soi plusieurs telles boucles en forme de huit.Alternatively, the detection ring 15 is arranged in the shape of an eight so as to make it insensitive to parasitic emissions which may be present in the premises containing the objects to be monitored. It is possible to arrange, in a manner known per se, several such eight-shaped loops.

Cette rupture de l'anneau de détection est immédiatement détectée par le module électronique et celui-ci envoie, par son antenne 14 utilisée en émission, un signal qu'interprète le réseau de surveillance interne du magasin.This rupture of the detection ring is immediately detected by the electronic module and the latter sends, by its antenna 14 used in transmission, a signal interpreted by the internal monitoring network of the store.

Le signal émis par le module électronique d'un dispositif de marquage selon l'invention peut être un simple signal d'alarme, mais peut également être porteur d'informations donnant la nature exacte de l'objet en cause.The signal emitted by the electronic module of a marking device according to the invention can be a simple alarm signal, but can also carry information giving the exact nature of the object in question.

Dans la zone de sortie, des moyens de surveillance semblables à ceux couramment utilisés à l'heure actuelle assurent la détection de tout objet porteur d'une étiquette que celle-ci soit entière ou qu'il n'en reste plus que la partie portant le module électronique.In the exit area, surveillance means similar to those commonly used today ensure the detection of any object bearing a label whether it is complete or only the part carrying the electronic module remains.

L'utilisation d'un module électronique avec lequel l'on peut faire dialoguer des moyens de détection permet d'éviter des détections intempestives dans les zones de sortie.The use of an electronic module with which it is possible to communicate detection means makes it possible to avoid untimely detections in the exit zones.

Le pion enfermant le module électronique peut être moulé dans une matière transparente afin de permettre des transmissions d'informations par signaux lumineux.The pin enclosing the electronic module can be molded in a transparent material in order to allow transmission of information by light signals.

De manière connue en soi dans le domaine de la fabrication par moulage d'articles en matière plastique, lesdits dispositifs de marquage peuvent être décorés au moment de leur moulage sur toute leur surface ou seulement en partie ou peuvent être décorés par la suite, à la demande, en fonction de la destination des dispositifs de marquage.In a manner known per se in the field of manufacture by molding of plastic articles, said marking devices can be decorated at the time of their molding over their entire surface or only partially or can be decorated subsequently, at the request, depending on the destination of the marking devices.

Il est également possible de réaliser en une seule opération de moulage l'étiquette portant le circuit électronique de détection.It is also possible to produce, in a single molding operation, the label carrying the electronic detection circuit.

D'autres variantes de réalisation des dispositifs de marquage selon l'invention sont représentés aux figures 5 à 8.Other alternative embodiments of the marking devices according to the invention are shown in FIGS. 5 to 8.

La figure 5 représente une variante de réalisation d'un dispositif de marquage selon l'invention sous forme d'étiquette adhésive dans laquelle deux antennes réceptrices/émettrices sont prévues afin d'augmenter les chances de conserver une antenne capable de transmettre les informations après une tentative d'arrachage de l'étiquette.FIG. 5 represents an alternative embodiment of a marking device according to the invention in the form of an adhesive label in which two receiving / transmitting antennas are provided in order to increase the chances of keeping an antenna capable of transmitting information after a attempt to tear off the label.

Il est bien entendu possible d'augmenter le nombre desdites antennes si les dimensions de l'étiquette le permettent.It is of course possible to increase the number of said antennas if the dimensions of the label allow it.

Afin d'améliorer la capacité de rupture de l'anneau de détection, l'on inverse sur son pourtour les surfaces adhésives afin qu'il reste au moins en partie collé sur l'objet protégé lors de l'arrachage de l'étiquette.In order to improve the breaking capacity of the detection ring, the adhesive surfaces are inverted around its periphery so that it remains at least partially stuck on the protected object when the label is torn off.

En laminant de plus les antennes 14 dans le corps de l'étiquette afin d'assurer que celles-ci ne soient pas rompues lors de l'arrachage, l'on améliore encore la fiabilité de l'étiquette en ce qui concerne la détection d'un arrachage.By further laminating the antennas 14 in the body of the label in order to ensure that these are not broken during the tearing, the reliability of the label is further improved as regards the detection of 'a grubbing up.

Une telle disposition permet de s'affranchir de la nécessité de former des lignes de fragilisation.Such an arrangement eliminates the need to form lines of weakness.

La figure 6 représente une autre variante de réalisation dans laquelle le dispositif de marquage selon l'invention prend la forme d'une étiquette rigide épaisse accrochée sur un objet par la mise en place d'un insert 20 semblable aux dispositifs de marquage souvent utilisés à l'heure actuelle pour les vêtements.FIG. 6 represents another variant embodiment in which the marking device according to the invention takes the form of a thick rigid label hung on an object by the installation of an insert 20 similar to the marking devices often used for the current time for clothing.

A la différence des dispositifs connus de ce type, le dispositif de la figure 6 renferme un module électronique 23, une antenne réceptrice/émettrice 24 et un anneau de détection 25. La continuité électrique de cet anneau de détection 25 est assurée par l'insert 20 lorsque celui-ci est en place par l'appui sur ses faces des ressorts 26.Unlike known devices of this type, the device in FIG. 6 contains an electronic module 23, a receiver / transmitter antenna 24 and a detection ring 25. The electrical continuity of this detection ring 25 is ensured by the insert 20 when the latter is in place by the support on its faces of the springs 26.

Dès que l'on retire ledit insert, la continuité électrique dudit anneau de détection 25 est rompue ce qui provoque l'émission d'un signal à destination des moyens de surveillance.As soon as said insert is removed, the electrical continuity of said detection ring 25 is broken, which causes a signal to be sent to the monitoring means.

Dans ce mode de réalisation, l'insert peut être prévu de manière à être retiré de manière simple, ce qui n'est pas le cas avec les dispositifs connus de ce type, du fait que tout retrait non autorisé est détecté par le fait qu'il ouvre l'anneau de détection.In this embodiment, the insert can be provided so as to be removed in a simple manner, which is not the case with known devices of this type, since any unauthorized removal is detected by the fact that 'it opens the detection ring.

Dans la variante représentée à la figure 7, le dispositif de marquage est une capsule de bouteille composée de manière connue en soi d'un bouchon 31 et d'une bague de sertissage 30.In the variant shown in FIG. 7, the marking device is a bottle cap composed in a manner known per se of a stopper 31 and a crimping ring 30.

Cette capsule renferme un module électronique 33, une antenne 34 et un anneau de détection 35 noyés dans la matière. Le module électronique 33 et l'antenne 34 sont totalement disposés dans le bouchon 31 comme, représenté à la figure, ou dans la bague de sertissage 30, tandis que l'anneau de détection 35 est disposé en partie dans le bouchon 31 et en partie dans la bague de sertissage 30.This capsule contains an electronic module 33, an antenna 34 and a detection ring 35 embedded in the material. The electronic module 33 and the antenna 34 are completely arranged in the plug 31 as, shown in the figure, or in the crimping ring 30, while the detection ring 35 is partly arranged in the plug 31 and partly in the crimp ring 30.

Par une telle disposition, dès que l'on tente d'ouvrir la bouteille en désolidarisant le bouchon 31 de la bague de sertissage 30, l'anneau de détection 35 est rompu et l'alerte est donnée.By such an arrangement, as soon as an attempt is made to open the bottle by separating the cap 31 from the crimping ring 30, the detection ring 35 is broken and the alert is given.

Une telle disposition fonctionne avec tout type de capsule pour lesquelles l'on doit désolidariser le bouchon d'une bague de sertissage, que ce soit en dévissant le bouchon, en tirant sur une languette d'arrachage de la bague, ainsi que pour les dispositifs dans lesquels la bague se sépare en plusieurs parties lors du dévissage du bouchon.Such an arrangement works with any type of capsule for which the plug must be detached from a crimping ring, either by unscrewing the plug, by pulling on a pull tab on the ring, as well as for the devices. in which the ring separates into several parts when the cap is unscrewed.

La figure 8 représente une nouvelle variante de réalisation d'un dispositif de marquage selon l'invention sous la forme d'une étiquette 40 accrochée à un objet, par exemple un bagage ou un conteneur, par des fils 45.FIG. 8 represents a new alternative embodiment of a marking device according to the invention in the form of a label 40 attached to an object, for example luggage or a container, by wires 45.

Dans cette forme de réalisation, les fils 45 forment l'anneau de détection. Ces fils peuvent à cet effet être reliés électriquement entre eux par une pastille 49 conductrice.In this embodiment, the wires 45 form the detection ring. These wires can for this purpose be electrically connected to each other by a conductive pad 49.

La coupure de l'un et/ou l'autre fil 45 est détectée par le module électronique non représenté contenu dans le pion 48, et un signal est émis par une antenne, également non représentée, contenue dans le pion 48.The break in one and / or the other wire 45 is detected by the electronic module, not shown, contained in the pin 48, and a signal is transmitted by an antenna, also not shown, contained in the pin 48.

La détection peut constater la rupture de la continuité du circuit comme décrit dans les exemples précédents, mais peut également constater une modification des caractéristiques électriques du circuit de détection.The detection can note the rupture of the continuity of the circuit as described in the previous examples, but can also note a modification of the electrical characteristics of the detection circuit.

Dans le cas où seule la rupture de continuité est détectée par le module électronique, une personne mal intentionnée, pourrait faire une jonction des fils au milieu de leur longueur de manière à former un nouvel anneau de détection fermé, puis couper les fils près de leur extrémité pour enlever l'étiquette.In the case where only the break in continuity is detected by the electronic module, an ill-intentioned person could join the wires in the middle of their length so as to form a new closed detection ring, then cut the wires near their end to remove the label.

Pour détecter ce type de fraude, le module électronique est prévu de manière à pouvoir détecter une variation de la résistance du circuit due, ici, au raccourcissement des fils.To detect this type of fraud, the electronic module is provided so as to be able to detect a variation in the resistance of the circuit due, here, to the shortening of the wires.

L'on peut également prévoir d'éxaminer la conductance ou l'inductance de l'anneau de détection.Provision may also be made to examine the conductance or inductance of the detection ring.

L'étiquette 40 peut être de toute forme connue ou être réalisée comme un dispositif selon l'invention, c'est-à-dire contenir elle aussi un anneu de détection permettant la détection d'un déchirement.The label 40 can be of any known form or be made as a device according to the invention, that is to say also contain a detection ring allowing the detection of a tear.

Les figures 9 et 10 montrent deux exemples de réalisation du circuit électronique pour des dispositifs de marquage selon l'invention.Figures 9 and 10 show two embodiments of the electronic circuit for marking devices according to the invention.

Sur ces dessins, le composant électronique mis en oeuvre est représenté par le cadre 53 ou 63.In these drawings, the electronic component used is represented by box 53 or 63.

Il reçoit des informations sur l'état du dispositif de marquage par l'anneau de détection 55 et est en relation avec un système de surveillance par l'antenne 54.It receives information on the state of the marking device by the detection ring 55 and is in relation to a surveillance system by the antenna 54.

Dans les exemples non limitatifs de réalisation de ces figures 9 et 10, l'antenne est unique et assure la réception et l'émission de messages sur une même fréquence porteuse.In the nonlimiting exemplary embodiments of these Figures 9 and 10, the antenna is unique and ensures the reception and transmission of messages on the same carrier frequency.

Dans les exemples représentés, une bobine 50 assure la fourniture en énergie du module électronique, elle peut être constituée par l'anneau de détection ou toute autre bobine comprise dans le dispositif, par exemple les antennes 14 de figures 3 et 5.In the examples shown, a coil 50 provides the energy supply to the electronic module, it can be constituted by the detection ring or any other coil included in the device, for example the antennas 14 of FIGS. 3 and 5.

Cette énergie est redressée et stabilisée dans le récepteur-redresseur 70.This energy is rectified and stabilized in the receiver-rectifier 70.

Un fusible 71 est disposé entre la bobine 50 et le récepteur-redresseur 70.A fuse 71 is disposed between the coil 50 and the receiver-rectifier 70.

Un circuit 72 assure la réception et la démodulation des informations captées par l'antenne 54 et envoie ces informations vers un dispositif de traitement des données 74.A circuit 72 receives and demodulates the information received by the antenna 54 and sends this information to a data processing device 74.

Ledit dispositif de traitement des données 74 reçoit également un signal d'horloge en provenance du circuit 75.Said data processing device 74 also receives a clock signal from circuit 75.

A partir des informations reçues soit du circuit 72 de réception et démodulation, soit de l'anneau de détection 55, ce dispositif de traitement des données 74 délivre au circuit 73 un signal qui est modulé et émis par l'antenne 54.From the information received either from the reception and demodulation circuit 72 or from the detection ring 55, this data processing device 74 delivers to the circuit 73 a signal which is modulated and transmitted by the antenna 54.

Lorsqu'un tel dispositif passe entre les antennes émettrice/réceptrice du système de surveillance disposées à la sortie de la zone surveillée, il reçoit dudit système de surveillance un signal d'appel, par exemple sous forme d'une modulation de la fréquence porteuse.When such a device passes between the transmitting / receiving antennas of the surveillance system arranged at the exit from the monitored zone, it receives from the surveillance system a call signal, for example in the form of modulation of the carrier frequency.

Le dispositif de traitement des données 74 identifie ce signal d'appel et déclenche l'émission d'un signal de réponse par le circuit 73.The data processing device 74 identifies this call signal and triggers the transmission of a response signal by the circuit 73.

Ces signaux d'appel et de réponse peuvent bien entendus être codés, par exemple par l'utilisation de fréquences de modulation différentes.These call and response signals can of course be coded, for example by the use of different modulation frequencies.

Lorsque l'on tente d'arracher le dispositif de marquage de l'objet qui le porte, le dispositif de traitement des données 74 reçoit l'information de l'anneau de détection 55 et déclenche l'émission d'un signal.When an attempt is made to tear off the marking device from the object carrying it, the data processing device 74 receives the information from the detection ring 55 and triggers the emission of a signal.

Dans un troisième cas, celui au cours duquel l'article est amené en caisse par un acheteur, un apport d'énergie important est réalisé, conduisant à la destruction du fusible 71.In a third case, that in which the article is brought to the cashier by a buyer, a significant energy supply is made, leading to the destruction of the fuse 71.

L'exemple de réalisation représenté à la figure 10 diffère de celui représenté à la figure 9 en ce qu'il comporte un module de sécurité 76 formé par un calculateur et une mémoire 77 accessible uniquement par ce module de sécurité.The embodiment shown in Figure 10 differs from that shown in Figure 9 in that it includes a security module 76 formed by a computer and a memory 77 accessible only by this security module.

Cette forme de réalisation permet d'établir un dialogue entre le système de surveillance et l'étiquette. La mémoire peut contenir des données spécifiques au produit, au magasin, etc ...This embodiment makes it possible to establish a dialogue between the surveillance system and the label. The memory can contain data specific to the product, the store, etc.
