Definitions

  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • the marking devices according to the invention also allow the management of objects carrying said devices.
  • the marking device comprises an electronic module 13 and a ring 15 for detecting an attempted fraud.
  • 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.
  • 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.
  • 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.
  • an energy field preferably a radio-electric field.
  • 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.
  • 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.
  • an electronic module capable of storing information and of transmitting and / or receiving information is implemented either alone or through an antenna.
  • the detection ring 15 is used as an antenna.
  • the digital signals emitted by the electronic module can also be coded in order to easily distinguish them from other external parasitic signals.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • the conducting wire forming the detection ring 15 can be used as the antenna for transmitting this signal.
  • the surveillance service is thus, thanks to the label according to the invention, immediately warned of the attempted fraud.
  • the marking device can no longer receive power, which makes it mute in the room.
  • 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.
  • 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.
  • FIGS. 2a to 2e show the steps for manufacturing a device of this type.
  • 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.
  • one of the corners of said blank has an L-shaped cutout 5.
  • 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.
  • a second blank 6 is also cut from the ribbon of material in the step shown in FIG. 2c.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • the marking device 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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 ...
  • 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.
  • 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.
  • the marking device comprises, in addition to the detection ring 15, a transmitting / receiving antenna 14.
  • 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.
  • 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.
  • This manufacturing is done in several stages.
  • 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.
  • 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.
  • cuts of different shape and nature are made in the tape 1 at suitably chosen locations.
  • 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).
  • a second cut 12 consists in the removal of a generally L-shaped surface of material.
  • 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.
  • the electronic module 13 is placed in the region of the ribbon 1 bordered by the concave part of the blank 12.
  • 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.
  • 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.
  • the conductors 14 and 15 are laminated in the material forming the ribbon 1.
  • the upper face of the ribbon can be decorated if it had not been previously.
  • 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.
  • 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.
