Description

[0001]
[Industrial application fields]
The present invention relates to a defense device for monitoring the displacement of objects and unauthorized movement outside the enclosure, and more particularly, an indicator such as a label for the object to be monitored. Marking device with About.
[0002]
[Prior art]
Most defense devices used to date use signs that are detected when they pass through the surveillance zone. This type of defense device is currently used in stores, is attached to merchandise with labels, and its presence is detected when passing between antennas located near various exit passages and registers. .
[0003]
Such a defense system cannot be said to be absolutely reliable, such as the label may be removed from the product before the product leaves the store, and as a result, the shoplifted (theft) product cannot be detected. .
[0004]
As a result, more and more large signs are used and it becomes increasingly difficult to remove goods without damaging them without special tools from the goods to which they are attached.
[0005]
In addition, these signs maintain their detectability while attached to the object to which they are attached, so even after legitimately passing the surveillance zone, i.e. even after the goods have been legitimately acquired. , Have the ability to detect them. When a person who purchases a product at one store passes through another store, the defense system is activated, and when leaving the second store, the defense is triggered, and there are many cases in which unsuspecting suspicions are raised.
[0006]
Thus, a need arises for active beacons that respond only to specific requirements, such as when passing between control band antennas. It can communicate that the sign is removed or destroyed, and can be destroyed when the function of the sign is achieved, i.e. once the merchandise has been fully purchased Is.
[0007]
Nathans US Pat. No. 3,713,133 suggests a safety pin attached to the product with a safety pin, on the one hand allowing detection by the monitoring device when passing the monitoring zone, and opening the safety pin on the other If the sign is removed from the product, it is detected by the in-store monitoring device.
[0008]
This sign allows for more effective monitoring. This is because an alarm is issued as soon as an unauthorized person opens the safety pin. However, if the person trying to steal tries to partially damage the sign, it is still insufficient. For example, in the case of clothes, it can be removed without opening the safety pin by tearing the sign.
[0009]
[Problems to be solved by the invention]
It is an object of the present invention to provide a sign that issues an alarm if the sign is to be removed.
[0010]
[Means for Solving the Problems]
The labels of the present invention to solve the above problems have detector rings that change electrical properties if they are to be removed from their substrates.
[0011]
The sign of the invention also advantageously allows the substrate of the device to be controlled according to the invention.
[0012]
[Action]
The operation of the present invention will become apparent from the following description of non-limiting embodiments which will be described in detail with reference to the accompanying drawings.
[0013]
【Example】
In the first embodiment shown in FIG. 1, the sign has an electronic module 13 and a detector ring 15 that detects an attempt to steal.
[0014]
The electronic module is optional as long as the intended control is in place, and may include one or more electronic chips and / or planar components.
[0015]
The conductor 15 holding the detector ring is very thin and can be easily destroyed. The surface can be large, but its thickness must be so thin that it is destroyed.
[0016]
Furthermore, the conductor 15 can supply power to the electronic module 13 by exposing the label to an energy field, preferably a radio electric field. In the monitoring zone, such a field induces a current in the conductor 15 that is rectified in a known manner to power the electronic module.
[0017]
While this sign is primarily intended for merchandise monitoring in stores, they can also be used in museums and other exhibition halls.
[0018]
In general, the surveillance band is an enclosed place, so it is very easy to set up a radio field inside it to activate the sign of the present invention.
[0019]
For large-area shops and exhibition halls, the electric field may be sufficient to power the sign of the present invention if it is set by illuminating the interior. Therefore, it is not necessary to provide a special power source.
[0020]
By appropriate selection and programming of the sign electronic module of the present invention, the sign can further interact with inventory and / or price management circuitry. For this purpose, an electronic module capable of storing and transferring and / or receiving data can be used as such or via an antenna relay.
[0021]
In this embodiment mode, the detector ring 15 serves as an antenna.
[0022]
The digital signal emitted from the electronic module can also be coded so that it can be easily distinguished from other external noise signals.
[0023]
The sign of the present invention is intended to operate in a store provided with a surveillance system typically used in a surveillance system that detects theft in the store along with a carry-out control and surveillance system.
[0024]
These thefts include removing the sign from the merchandise.
[0025]
In the present invention, the electronic circuit mounted on the label ensures that a signal is sent immediately if someone other than the authorized person attempts to remove the label from the item.
[0026]
Attempts to remove the sign are detected by detector ring 15. And for this reason, the detector has a very thin cross-sectional shape so that if the sign is to be removed from the substrate, the conductor is broken so that electrical continuity is lost and the conductor is allowed to break down. It is clearly stated that
[0027]
In one alternative embodiment, the sign is in the form of an adhesive label that is adhered to a product for sale or display.
[0028]
The sign is adhered to the entire surface of the item to be protected. The product cannot be severely damaged because it cannot be cut to remove the label so that it can be in close proximity.
[0029]
Therefore, the only way to obtain this item without fear of being detected in the control zone is to remove the label.
[0030]
To do so, however, the label is distorted and pulled, so that the detector ring 15 is placed in one or more parts.
[0031]
This electrical discontinuity in the detector ring 15 is immediately detected by the electronic module, whereby the electronic module transmits a signal, picked up by the monitoring device, analyzed and spread into the store.
[0032]
The conductor forming the detector ring 15 is used as an antenna for transmitting the above signal.
[0033]
Thanks to the label according to the invention, the surveillance task can thus give an immediate warning against theft.
[0034]
Once a signal for theft is being sent, the mode indicator of this embodiment will no longer lose power and no longer signal in the store.
[0035]
However, because the sign is designed in this way, the electronic module remains attached to the merchandise, then the label is removed, detected by the store exit monitoring device and believed to have been released from the merchandise sign A second method of intercepting is provided.
[0036]
For that purpose, the label consists of several peelable layers, so that the detector ring 15 is carried on the outer layer of this label, so that it can be easily broken and easily removed from the label substrate and adhered. The agent and other residue adhered to the substrate is removed from the electronic module.
[0037]
The steps of the production process of this kind of label are shown schematically in FIGS. 2a to 2c.
[0038]
In the first stage shown in FIG. 2a, the first margin 2 roughly shows the shape of the label. However, it is preferably smaller than the cut-out portion of the tape 1.
[0039]
As shown in FIG. 2b, one of the margin corners clearly shows an L-shaped notch. It is covered with metal and has conductivity, and a circular portion 3 is formed along the first margin 2 as shown in the figure. They are close to the periphery, and the electronic module 5 is attached to the edge where the notch is recessed.
[0040]
The second blank portion 6 is also formed in the cut portion of the tape at the stage shown in FIG. 2c.
[0041]
The second blank portion 6 has a corner notch 8 corresponding to the corner of the electronic module of the first blank portion 2, and the two blank portions 2 and 6 are as shown in FIG. 2d. When overlaid, it has an opening 7 that is disposed opposite the metallized portion.
[0042]
Once the two margins are overlaid so that the opening 7 and the metal covering 3 are facing each other and they are joined together with an adhesive film, the detector ring 9 attaches the conductive strip to the first margin. Formed by placing on the second margin 6 on the part 2 itself, the strip is joined to the metallized part 3 of the first margin 2.
[0043]
On top of that, an electronic module is cast in the protruding portion 101, and an adhesive film covered with a protective sheet is fixed to the back of the label.
[0044]
The above margins 2 and 6 are weaker than the adhesive force on the back surface of the label and are adhered to each other by an adhesive.
[0045]
Therefore, if the label 100 made as described above is glued to the object, if the label 100 is peeled off, the margin 2 remains glued to the object, but the top margin 6 is peeled off and the detector is removed. Ring continuity is destroyed.
[0046]
In the mode of this embodiment, the margin 6 can describe useful data such as price, barcode, etc., and the decoration can be printed or embossed on the margin 2 on the lower layer side. Therefore, the purchaser of the product can remove the upper margin 6 and leave the lower margin 2 on the product to store the decoration.
[0047]
The sign of the present invention can be used for a bona fide customer who does not want to remove the label in order to review the product. It is clear that it will not prevent you from returning.
[0048]
If the labeled item is properly moved to the store register, the coded electrical signal then directs the electronic circuit by detector ring, which then acts as an antenna. This signal has enough power to evaporate the fuse. This requires that the fuses be bundled into an electronic module in a known conventional manner. This destruction signal can be fired when the barcode on the label is read to identify the item and read its price.
[0049]
Since an electronic module is used, valid fuse destruction can be checked before valid price entry, so that deactivation of the sign can be confirmed.
[0050]
Thus, once the goods are properly taken out of the store, the label of the present invention becomes inactive, so that after paying for the goods, it may be stopped by other store monitoring systems This product will not be detected.
[0051]
The energy storage of such a label can be increased by using a capacitor in the electronic circuit. Such a capacitor can be obtained by direct printing or by laminating conductive layers.
[0052]
In order to increase the possibility of breakage at some positions when the label is stressed so that the label surely and unavoidably deteriorates the detector ring 15, a weak part emphasis means, for example, Breakage lines etc. are provided on the label.
[0053]
The above description is clearly merely instructive, but the label of the present invention, for example, certifies that it is the same person or the same product when passing the trigger means, or classifies the package by size in the postal business It has versatility and versatility, such as sorting baggage at airports and waste bags at garbage disposal sites.
[0054]
The label of the present invention thus detects the identification of persons or goods, theft or fraud, for example, those who are allowed to transfer to an unauthorized person or those who break the label to steal the package And the above label can be deactivated when the person or object carrying it leaves the monitoring zone.
[0055]
The electronic module can be equipped with a memory that allows storing useful data. A microprocessor that can be coupled with external means is provided for processing the data. Therefore, the sign of the present invention can also be used in a sorting parcel.
[0056]
In certain alternative embodiments for special applications, external contacts may be provided on the label to allow further interaction with a suitable reading means such as a chip card.
[0057]
With respect to the variant shown in FIG. 3, the sign of the present invention comprises a transceiving antenna 14 in addition to the detector ring 15.
[0058]
In the mode of the above-described embodiment, power is supplied to the electronic module as long as the antenna is kept intact even after the detector ring 15 is broken.
[0059]
In such a case, when it is attempted to be stolen, it is possible to interact with an electronic module for example for confirmation of merchandise and / or searching for it in the monitoring band.
[0060]
FIGS. 4a to 4f show a non-limiting production procedure for the label of the embodiment shown in FIG. 3, in the form of an adhesive label that can be applied to any object.
[0061]
This manufacturing procedure involves several stages.
[0062]
In the illustrated example, the label is made of a substrate tape such as polystyrene, polyvinyl chloride or ABS. This tape is prepared in advance by a known manufacturing method such as lamination, casting, extrusion, or injection. It is clear that other materials such as polyamide can be used as the material for the tape.
[0063]
This tape should be pre-decorated on the side that will be the surface of the label. A one-dot chain line 10 in the figure indicates the position of the label to be manufactured.
[0064]
In the first manufacturing stage, blanks of different shapes and personalities are cut out from the tape 1 at appropriate positions.
[0065]
The first set of cuts indicated by line 11 will correspond to the dashed line in the label. These cut portions are schematically indicated by a continuous line of dots like a normal cut line of a data processing sheet. As a result, the label emphasizing the fragile portion is easy to handle both in the manufacturing process and in use (attached to an object).
[0066]
The second cutting part 12 is formed by removing the L-shaped label surface.
[0067]
In the manufacturing process of the second stage, the electronic module 13 and the conductors 14 and 15 are obtained, a transmitting / receiving antenna is formed, and the detector ring is fixed to the tape 1. The conductors 14 and 15 are soldered to the electronic module, on which the module and solder joint are preferably coated with a protective varnish.
[0068]
As shown in FIG. 4 c, the electronic module 13 is located in that band of the tape 1. It is adhered to the recessed portion of the cutout 12.
[0069]
These components are attached to the back side of the label.
[0070]
In a variant embodiment, the electronic circuit is provided on a polyamide film to be coated on the tape 1, for example, with the conductor and the module separated. In that case, since it is necessary to pay attention to emphasize the weak part of the polyamide film around the detector ring, the cutting part 11 retains the importance of the above-mentioned weak part.
[0071]
At the stage shown in FIG. 4d, the tape band carrying the electronic module 13 is deflected to move the module from the rest of the tape surface. In this way, separation within the recess that houses the electronic module is achieved.
[0072]
In this case, the tape 1 carrying the electronic module is arranged inside the mold in order to be accommodated in the protective protrusion 18. At the same time, the conductors 14 and 15 are laminated inside the tape 1.
[0073]
In the next manufacturing process, the adhesive film 16 protected by the protective film 17 is placed on the back surface of the label, and the tape 1 is cut along the line 10. As such, it is a known method, and only the tape is cut without damaging the protective film.
[0074]
Finally, in the stage shown in FIG. 4f, the tape 1 carrying the finished label 21 is wound up. Therefore, there is a need for a material that is inserted between the bends that allows the thickness difference between the protrusion 10 and the other part of the label to be adjusted.
[0075]
Immediately thereafter, the tape is prepared for use in a known gluing machine.
[0076]
It is clear that the label may be manufactured by other methods of adding an antenna following the procedure shown in FIGS. 2a to 2e.
[0077]
The use of tape is clearly shown, of course, and the label 100 can be made of any other substrate, for example, a plate from which the label can be cut out in the steps shown in the series of figures.
[0078]
As shown in FIG. 4c, the detector ring 15 is arranged at the periphery of the label so that it is destroyed before the antenna 14 may be damaged. Further, the weak line 11 is arranged so as not to pass through the antenna 14 in order to limit the deterioration of the antenna 14.
[0079]
In one embodiment variant, the detector ring 15 is shaped like an 8 in order to make the antenna insensitive to noise generated in the monitored store. Some of these eight-shaped loops can be used in a manner known per se.
[0080]
The above destruction of the detector ring 15 is immediately detected by the electronic module that sends the signal analyzed by the in-store monitoring system through its antenna 14 in the transmission mode.
[0081]
The signal transmitted by the electronic module of the sign of the present invention may be a simple alarm signal, but can also be a data carrier that determines the essence of the object.
[0082]
A monitoring system similar to the currently used monitoring system detects any label-carrying object in the exit zone when the label is complete, whether or not it simply holds the part carrying the electronic module To do.
[0083]
The use of an electronic module that interacts with the sensing means allows to avoid fault detection in the exit zone.
[0084]
The protrusion 18 enclosing the electronic module can be molded of a transparent material in order to allow data transmission by an optical signal.
[0085]
In the manner known per se in the plastics molding field, the above-mentioned signs can be decorated on their entire surface or only a part thereof during molding, or they are required by the function of their intended use. Depending on the, it can also be subsequently decorated.
[0086]
Furthermore, the label carrying the electronic detection circuit can be molded in a single operation.
[0087]
The mode of another embodiment of the sign of the present invention is shown in FIGS.
[0088]
FIG. 5 shows an embodiment of the present invention in the form of an adhesive label with two antennas to increase the possibility of protection of one antenna so that information is transmitted as a result of attempting to separate the signs. An alternative embodiment with a sign is shown.
[0089]
As can be seen, the number of antennas can be increased within the constraints of the label size.
[0090]
To increase the ability of the detector ring to break so that at least a portion of the ring remains adhered to the protected object when the label is torn off, the adhesive surface is aligned along its periphery. It is bent in the opposite direction.
[0091]
By additionally covering the label main body with the antenna 14 so that the antenna is not damaged even if the label is peeled off, the reliability of the label peeling detection is further enhanced.
[0092]
Such a design is independent of vulnerability.
[0093]
FIG. 6 shows that the sign of the present invention is in the form of a thick and rigid label fixed on an object by using an insert 20 similar to the conventional sign currently used for clothing. Another modified embodiment is shown.
[0094]
In contrast to this type of known sign, the sign shown in FIG. 6 has an electronic module 23, a transmitting / receiving antenna 24 and a detector ring 25. The electrical continuity of the detector ring 25 is provided by the insert 20 when the detector ring 25 is mounted in place and loaded with a spring 26.
[0095]
As soon as the insert is removed, the electrical continuity of the detector ring 25 is lost, thereby sending a signal to the warning means.
[0096]
In this embodiment mode, the insert is mounted so that it can be removed in a simple manner, unlike with known devices of this kind. This is because any unauthorized extraction is detected by the subsequent opening of the detector ring.
[0097]
For the mode of the embodiment of FIG. 7, the indicator is a heel cap consisting of a known stopper 31 and a pleated ring 30.
[0098]
The cap surrounds the electronic module 33, the antenna 34, and the detector ring 35, all of which are embedded. The electronic module 33 and the antenna 34 are completely accommodated in the stopper 31 as shown in the figure. Otherwise, the detector ring 35 may be partially housed in the stopper 31 and partially wrapped in a pleated ring.
[0099]
In such a design, if the stopper 31 is not engaged with the pleated ring 30, the detector ring will be destroyed and an alarm will be issued when attempting to open the hook.
[0100]
Such a design can be used to open the stopper by twisting it back, pulling the torn tab of the ring to open it, or twisting the stopper back as a sign, and the ring can be disassembled into several parts. Even if it is of the type, it is applicable to any container that requires the stopper to be released from the annulus when opened.
[0101]
FIG. 8 shows one of the variations of the new embodiment of the sign of the present invention in which the label 40 is attached to the object with a wire 45, such as a travel bag or container.
[0102]
In this embodiment mode, the wire 45 forms the detector ring. For this purpose, these wires are electrically connected to each other by means of conductive pellets 49.
[0103]
One or both of the wires 45 are detected by an electronic module (not shown) housed in the protruding portion 48 of the label 40. The signal is transmitted from an antenna which is also housed in the protrusion 48 and omitted in the drawing.
[0104]
The detection procedure confirms the breakdown of the circuit conduction as described in the mode of the above embodiment, but may detect a change in electrical characteristics of the detection circuit.
[0105]
If only a loss of continuity is detected by the electronic circuit, the habitual villain will form a new closed detector ring, connect its center with a conductor, and then remove its label to remove the label. There is a possibility of cutting the wire at the part.
[0106]
In order to sense this type of theft, the electronic module is designed to sense changes in circuit resistance in the event of a wire short circuit.
[0107]
In addition, the conductance or inductance of the detector ring is also checked.
[0108]
The label 40 may be in any known shape or may be according to the method of the present invention. That is, the detector ring which detects destruction is included.
[0109]
9 and 10 show the modes of two embodiments of the sign electronic circuit of the present invention.
[0110]
In these figures, the electronic components used are indicated by boxes 53 and 63.
[0111]
The detector ring 55 supplies sign state data to the electronic components described above that are coupled to the monitoring system via the antenna 54.
[0112]
With respect to the mode of embodiment shown in a non-limiting manner in FIGS. 9 and 10, a single antenna carries information at the same carrier frequency.
[0113]
In the mode of the illustrated embodiment, the coil 50 that supplies power to the electronic module comprises a detector ring or other coil component of signage, such as the antenna 14 of FIGS.
[0114]
This electric power is rectified and stabilized by the rectification receiver 70.
[0115]
A fuse 71 is disposed between the coil 50 and the rectifying receiver 70.
[0116]
Circuit 72 performs the reception and demodulation of data picked up by antenna 54. This data is supplied to the data processing system 74.
[0117]
The data processing system 74 also receives a clock signal from the circuit 75.
[0118]
Based on data from either the receiving and demodulating circuit 72 or the detector ring 55, the data processing system 74 provides an output signal to the circuit 73. This output signal is modulated and transmitted by the antenna 54.
[0119]
When such a sign passes between the transmitting and receiving antennas of the monitoring system located at the exit of the monitoring zone, the monitoring system receives a paging signal from such monitoring system, for example in the form of a carrier frequency modulation.
[0120]
Data processing system 74 identifies this ringing signal and triggers a response signal from circuit 73.
[0121]
The call signal and answer signal will be clearly coded, for example by using different modulation frequencies.
[0122]
If an attempt is made to tear the sign from its substrate, the data processing system 74 receives this information from the detection signal 55 and triggers the signal.
[0123]
In the third case, i.e., when the item is brought to the register by the purchaser, material energy is applied, resulting in the fuse 71 being destroyed.
[0124]
The mode of the embodiment shown in FIG. 10 differs from FIG. 9 by including a safety module 76 consisting of a computer and memory 77 that can only be used in that module.
[0125]
This latter embodiment mode allows interaction between the monitoring system and the label. In particular, the memory may include data regarding products, stores, and the like.
[0126]
【The invention's effect】
As described above, according to the present invention, if an object such as a commodity with a sign is passed through a monitoring zone such as an exit passage, the sign is detected by an antenna provided at the exit or the like, and an alarm is issued. Also, if you try to remove the sign from the product in the store with the intention of taking it out illegally, the electrical characteristics of the detector ring incorporated in the sign will change and an alarm signal will be issued immediately, so you can be sure that the product has been taken out illegally. Therefore, the damage caused by illegal takeout due to theft can be surely prevented.
