Definitions
- An Electronic Article Surveillance (EAS) system is designed to prevent unauthorized removal of an item from a controlled area.
- a typical EAS system may comprise a monitoring system and one or more security tags.
- the monitoring system may create an interrogation zone at an access point for the controlled area.
- a security tag may be fastened to an item, such as an article of clothing. If the tagged item enters the interrogation zone, an alarm may be triggered indicating unauthorized removal of the tagged item from the controlled area.
- the security tag must be deactivated before a tagged item can leave the controlled area without triggering the alarm.
- Security tags may take a variety of forms including soft tags and hard tags. In general, soft tags are disposable and used only once, while hard tags are reusable. An example of a soft tag is an adhesive-backed security label.
- a soft tag may be deactivated by a deactivator unit, such as a scanner that uses a specific field to deactivate the soft tag when it touches or comes in close proximity to the soft tag.
- Hard tags typically comprise a plastic tag body housing an EAS sensor and a locking mechanism including a pin or tack which passes through the item and is clamped to the tag body to secure the item and tag together.
- a hard tag requires a detacher unit to remove the tack from the tag body and allow the item to be separated from the hard tag.
- a detacher unit may include a magnet assembly which applies a magnetic field to the tag body for releasing the tack.
- US 6,084,498 disclose a magnetic decoupler with a magnetic field shape, strength and gradient optimized for releasing security tags.
- the detacher disclosed in D1 comprises a magnet assembly for accessing a hard tag comprising a clamping mechanism and to provide a magnetic field sufficient to disengage said clamping mechanism of the tag, wherein the magnet assembly includes a quadrature magnet assembly and a ring magnet, arranged on top of the quadrature magnet assembly. Together with a steel cup covering both, the ring magnet and the quadrature magnet assembly, a closed magnetic detacher is provided which includes a cavity into which a nipple of a tag may be inserted.
- US 5,063,934 discloses a permanent magnet assembly for creating a uniform magnetic field across a portion of an air gap.
- the magnet assembly includes a first principle magnet, a pole piece contacting said principal magnet and a set of auxiliary magnets extending about the periphery of the pole piece.
- the teaching includes the positioning of two such magnet groups in a test chamber. No use of such a device in combination with a magnetic detacher is disclosed.
- the clamping mechanism of a hard tag may be embedded in the existing packaging of an item or may have a low profile to minimize vulnerability of defeats and facilitate shelving of items.
- a different detacher design is required to provide open access to the embedded or low profile clamping mechanism and, at the same time, providing a sufficient magnetic field.
- any reference in the specification to "one embodiment” or “an embodiment” means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment.
- the appearances of the phrase “in one embodiment” in various places in the specification are not necessarily all referring to the same embodiment.
- FIG. 3 illustrates one embodiment of a magnetic detacher 30.
- the magnetic detacher 30 comprises a magnet assembly 31 including a cylindrical magnet 32 and a ring magnet 33.
- the cylindrical magnet 32 and the ring magnet 33 may comprise one or more permanent magnets.
- permanent magnets have a defined magnetization axis dependent upon the magnetization process, orientation of the material, the geometry, and other material properties.
- the permanent magnets may comprise paramagnetic components such as samarium (Sm) and neodymium (Nd) and ferromagnetic components such as iron (Fe) and cobalt (Co).
- Sm samarium
- Nd neodymium
- Fe iron
- Co cobalt
- a crystalline domain structure may be created which exhibits oriented intra-domain magnetization known as magneto-crystalline anisotropy, which is the mechanism that produces strong magnetic fields.
- the permanent magnet may undergo processing including, for example, compression of components in the presence of an ambient magnetic field, sintering of the compressed material, and remagnetization.
- Examples of permanent magnets include but are not limited Neodymium Iron Boron (NdFeB) magnets, hard ferrite magnets, and cobalt magnets such as Samarium Cobalt (SmCo) magnets and Aluminum Nickel Cobalt (AlNiCo) magnets.
- the permanent magnets may comprise sintered and/or bonded magnets.
- the permanent magnets also may include a variety of coatings to deter corrosion.
- the magnetic detacher 30 is structured and arranged to provide open access to various magnetic clamping mechanisms. As such, the magnetic detacher 30 is capable of disengaging the clamping mechanism of a hard tag placed at any angular position relative to its axis. In various implementations, the magnetic detacher 30 is configured to provide a relatively symmetric field about its axis making it usable for hard tag placed at any angular position.
- a top surface 34 of the cylindrical magnet 32 is substantially coplanar and concentric with a top surface 35 of the ring magnet 33.
- the cylindrical magnet 32 and the ring magnet 33 are substantially flush allowing a hard tag to be received in any direction.
- the magnetic detacher 30 thus provides open access to various magnetic clamping devices in hard tags. The embodiments are not limited in this context.
- the top surface 34 of the cylindrical magnet 32 may be slightly offset upwardly or downwardly from the top surface 35 of the ring magnet 33.
- the top surface 34 of the cylindrical magnet 32 may offset by 2 to 3 mm higher or lower from the top surface 35 of the ring magnet 33. The embodiments are not limited in this context.
- the magnet assembly 31 comprises a ring magnet 33 that is magnetised radially.
- the ring magnet 33 may comprise, for example, multiple sections 36-1-n, where n represents a positive integer value and each of the multiple sections 36-1-n is magnetized in a direction pointing to the center of the ring magnet 33.
- the ring magnet 33 is quartered into a first section 36-1, second section 36-2, third section 36-3, and fourth section 36-4.
- the white arrows indicate the orientation of magnetization.
- magnetic flux is directed inwardly toward the center of the ring magnet 33 and bent upwardly and out of the ring magnet 33.
- the magnetic field of the ring magnet 33 adds to the upwardly pointing magnetic field generated by the core cylindrical magnet 32 resulting in a very strong magnetic field.
- the magnet assembly 31 provides a relatively symmetric field about its axis making the magnetic detacher 30 usable for a hard tag placed at any angular position.
- soft iron material can be placed at the bottom of the magnet assembly 31 to achieve keeper effect and enhance the surface field.
- the ring magnet 33 may be divided into four or more sections with each magnet section magnetized in a direction pointing to the center of the ring magnet 33. It can be appreciated that with less than four sections, the ring magnet 33 may have substantial field variation so that the clamping mechanism can only be disengaged at specific angular positions.
- TABLE 1 illustrates a comparison of magnetic surface fields in kilo-Gauss (kG) at the center on a cylindrical magnet for various magnet detacher configurations.
- the configurations may include a ring magnet having an inner diameter (ID), an outer diameter (OD), and height (h).
- the detacher configuration using only a single cylindrical magnet provides a much lower surface field than the detacher configurations using a magnet assembly.
- To achieve open access with a single magnet configuration would require employing only a cylindrical magnet, for example, by removing the ring magnet 22 from the conventional magnet assembly 20.
- Such approach compromises the detaching field as the clamping mechanism must be designed to be opened by a weaker magnet and thus made more susceptible to defeat by a "street" magnet.
- a similar field to that provided by the conventional detacher configuration using a ring magnet on a cylindrical magnet can be achieved with the appropriate choice of dimensions for a ring magnet that can fit over a cylindrical magnet.
- the detacher configurations using a ring magnet flush with a cylindrical magnet provide open access and a sufficient field with the appropriate choice of magnet dimensions.
- the height of the ring magnet e.g., ring magnet 33
- the outer diameter can be increased to about 60 mm to achieve a magnetic field level of about 7.1kG for such detacher configurations.
- the detacher configuration using a half ring magnet having a height of about 12 mm stacked on a cylindrical magnet also may provide a sufficient magnetic field while allowing open access from one side of the magnet assembly.
- the embodiments are not limited in this context.
- FIG. 4 illustrates one embodiment of a graph 60 illustrating magnetic field level as a function of ring magnet height for various magnetic detacher configurations using a ring magnet flush with a cylindrical magnet. As shown, further field enhancement is possible with a larger magnet.
- the embodiments are not limited in this context.
- FIG. 5 illustrates one embodiment of a graph 70 illustrating magnetic field level as a function of distance from the center of the magnet surface.
- various embodiments of the magnetic detacher have enhanced field projection as compared to the conventional magnet assembly.
- the magnetic detachers have a longer field projection allowing the magnetic detachers to disengage the clamping mechanism of a hard tag at greater distances as compared to the conventional magnet assembly.
- the embodiments are not limited in this context.
- the described embodiments comprise a magnetic detacher to provide open access to various hard tags and a sufficiently strong magnetic field level for disengaging the clamping mechanism of such hard tags.
- the described embodiments may be employed in a variety of tagging applications, such as tagging of bottles and compact discs, for example, where the clamping mechanism of a hard tag is embedded in the existing packaging of an item or may have a low profile to minimize vulnerability of defeats and facilitate shelving of items.
- the described embodiments avoid the need to use a high profile or protruding design in tagging applications such as tagging bottles and compact discs.
- a protruding clamp on a slender package such as that of a compact disc, jewel case, or eyeglass wear is often problematic since the protruding clamp is prone to being snapped off or other tampering.
- the use of a protruding clamp also hinders efficient use of shelf space since the protrusion consumes space and makes stacking or arranging merchandise difficult.
- the described embodiments comprise a magnetic detacher using a magnet assembly that provides a higher magnetic field level than a detacher configuration using only a single magnet. Such embodiments avoid the need to design the clamping mechanism of a hard tag to work with a weaker magnet which would lower defeat resistance.
