Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an article monitoring label (hereinafter simply referred to as a label) using an amorphous metal thin wire, which is used in a theft prevention system for goods or articles in retail stores and public facilities. ) Is related to.

[0002]

2. Description of the Related Art It is said that the damage caused by unauthorized removal of goods from retail stores such as department stores and supermarkets and public facilities such as libraries is increasing year by year. In order to prevent these from being taken out without permission, so-called theft prevention, a magnetic system that attaches a label using a soft magnetic material to the product and detects the magnetic field change generated by the soft magnetic material when the product passes through the detection area Has been applied. As a soft magnetic material applied to a label of a magnetic system, an amorphous metal material has recently been used for the purpose of improving the sensitivity and reliability of the system, and among them, an amorphous metal thin wire has been receiving attention (Japanese Patent Laid-Open No. 2000-242242). 61-153799).

In the conventional label using this amorphous metal thin wire, both ends of the tape are aligned with both ends of the amorphous metal thin wire. That is, in the conventional label, an amorphous metal thin wire is supplied between at least two tapes having a paper or film as a base material at the same speed as the tape, and the amorphous metal wire is made at the same length as the tape. Since the thin metal wire was cut and continuously processed into the shape of a label, both ends of the tape were aligned with both ends of the amorphous metal thin wire. FIG. 6 shows the shape of a conventional label. In this label, the amorphous metal thin wire 1 and the tape 2 have the same length, and the ends are completely aligned.

[0004]

Since the above-mentioned label is a label in which both ends of the tape are aligned with both ends of the amorphous metal thin wire, the labels are peeled one by one from the release paper tape for gripping the label. When affixing to a hand with a finger, if the label is pressed with a finger and stuck, the amorphous metal fine wire has a drawback that the fine wire scratches the finger and damages the finger. Also, when the item touched the clothes, there was a problem that the tip of the thin metal wire was caught by the clothes and the label was peeled off. This is because the amorphous metal wire used as the soft magnetic material has a diameter of about 0.1.
It is derived from the fact that it is a very thin wire of ~ 0.15 mm and is very hard and does not easily bend, like a needle.

[0005]

Means for Solving the Problems The inventors of the present invention have made earnest studies as a result of providing an article monitoring label that does not hurt a finger when attached to an article and is not caught on clothes. , Both ends of the tape base material constituting the article monitoring label are made several mm longer than the amorphous metal thin wire used as the soft magnetic material, and both ends of the amorphous metal thin wire are covered with the tape base material of the label constituent material. As a result, the present inventors have found that a label that does not hurt a finger when stuck on an article and that is not caught on clothes can be obtained, and thus the present invention has been accomplished.

That is, according to the present invention, the amorphous metal fine wire is held between at least two tapes having a paper or film as a base material, and the length of the amorphous metal fine wire is calculated from the length of the tape. The outline is an article monitoring label for use in an article take-out monitoring system in which both ends of the amorphous metal thin wire are located inside both ends of the tape.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION The present invention is described in detail below.
In the label of the present invention, as shown in FIGS. 1 and 2, the length of the amorphous metal thin wire 1 is the upper tape base material 2 and the lower tape base material 3 (hereinafter, these are collectively referred to simply as tapes). The length of the amorphous metal fine wire 1 is shorter than the length of the tape, and both ends of the amorphous metal thin wire 1 are located inside the both ends of the tape. The thin amorphous metal wire 1 is sandwiched between an upper tape base material 2 and a lower tape base material 3 made of paper or film, and fixed with an adhesive 4. An adhesive 5 is applied to the back surface of the lower tape base material 4, and the labels are fixed one by one on the release paper 6 at regular intervals. At the time of use, the label is peeled from the release paper 6 and attached to the product. At this time, the length of the amorphous metal thin wire 1 is approximately 30 to 10 although it varies depending on the magnetic system to be detected.
0 mm is suitable, and the length of the amorphous metal thin wire 1 is about several mm longer than the length of the tapes 2 and 3, specifically, 2 mm.
It is preferable to shorten the length by about 10 mm, and it is preferable that both ends of the amorphous metal thin wire 1 be positioned inside about 3 mm, specifically about 1 to 5 mm inside the both ends of the tapes 2, 3.

Since this amorphous metal thin wire 1 is cut from above the upper surface tape base material 2 as shown in the following manufacturing example, the upper surface tape corresponds to one cut end of the amorphous metal thin wire 1. Although the cut marks 7 remain on the base material 2, the top tape base material 2
Covers the amorphous metal thin wire 1 without being completely cut, and the end portion of the amorphous metal thin wire 1 is not exposed on the surface side of the upper surface tape substrate 2. There is no problem when sticking the product to an article and the problem of getting caught on clothes.

FIGS. 3 and 4 show another embodiment of the label of the present invention. FIG. FIG. 4 shows a label in which hard magnetic materials 8 having a large coercive force are arranged in a strip shape.
This is a label in which a hard magnetic wire 9 having a larger coercive force is arranged. In these labels, the hard magnetic materials 8 and 9 having a large coercive force are magnetized by an appropriate means to apply a bias magnetic field to the amorphous metal thin wire 1 to artificially generate an alarm signal as a used label. It is a type of label that can be lost.

As the amorphous metal thin wire 1, for example, Fe
_{77.5 -Si 7.5 -B 15, (Co} 0.94 -Fe 0.06) 72.5 -
_{Si 12.5 -B 15, (Co 0.67} -Fe 0.33) 70 -Cr 10 -
_{Si 8 -B 12, (Co 0.75} -Fe 0.25) 65.5 -Cr 12.5
An amorphous metal thin wire having a composition of —Mo ₂ —Si _7.5 —B _12.5 and a wire diameter of 100 to 130 μm is used.
As the hard magnetic material 8 having a large coercive force, for example,
CROVAC 15/150 (Vacuum Schmelze),
Arnachrome 3 (made by Arnold) is used, and as the hard magnetic wire 9 having a large coercive force, for example, CROVAC 10/130 (Vacuum Sch)
melze) and YHJ30-10 (made by Hitachi Metals) are used.

Next, a method of manufacturing a label according to the present invention will be described with reference to the drawings. FIG. 5 is a schematic process drawing showing an example of manufacturing the label of the present invention. In FIG. 5, first, an amorphous metal thin wire (hereinafter abbreviated as a wire) 1 is supplied from a bobbin 10 and a wire nip station 13 composed of a wire nip roller 11 and a counter roller 12 opposite to this roller is installed. After passing and oil is applied by the oiling unit 14, the oil is sent to a nip station 17 which is composed of a second nip roller 15 and a counter roller 16 facing the roller. On the upper side of the wire 1, the upper surface tape 2 coated with the adhesive 4 is supplied to the nip station 17, and on the lower side of the wire 1,
The lower surface tape 3 having the adhesive 5 and the release paper 6 on the back side is similarly supplied to the nip station 17. At the nip station 17, the upper surface tape 2, the lower surface tape 3 and the wire 1
And are sent to a wire cutting station 20 composed of a front wire cutting roller 18 and a counter roller 19 opposite to this roller. At the wire cutting station, the cutting blade 21 cuts the wire 1 together with the upper surface tape 2 and the lower surface tape 3.

Opposed roller 12 of wire nip station 13 and opposed roller 1 of nip station 17
By changing the peripheral speed between 6 and 6, the feeding speed of the wire 1 with respect to the upper surface tape 2 and the lower surface tape 3 can be delayed. At this time, as a supply speed ratio between the wire 1 and the upper surface tape 2 and the lower surface tape 3, the length of the wire 1 is 2 to 10 times larger than the length of the upper surface tape 2 and the lower surface tape 3.
It is desirable to select a speed ratio that shortens mm.
The wire 1 cut by the wire cutting station 20 slides between the nip station 17 and the wire cutting station 20 between the upper tape 2 and the lower tape 3. As described above, the wire 1 is applied with oil or the like by a suitable means such as the oiling unit 14 so as to improve the slip between the upper surface and the lower surface before being cut. The oil used for sliding the wire 1 may be a commercially available lubricating oil, but considering the rust of the wire 1, it is preferable to add a rust preventive agent.

Next, the upper surface tape 2 and the lower surface tape 3 sandwiching the cut wire 1 are sent to a die cutting station 24 composed of a die cutting roller 22 and an opposed roller 23 which is opposed to the roller, and the upper surface tape 2 and The lower surface tape 3 is cut out into a label shape, leaving the thickness of the release paper 6. Top tape other than label shape 2
The unnecessary portion of the lower surface tape 3 is removed by the dust removing roller 25, and the labels arranged at regular intervals on the release paper are wound on the product roll 26. By doing so, the label as shown in FIG. 1 is obtained.

EXAMPLES The present invention will be specifically described below with reference to examples. Example 1 A wire having a wire diameter of 125 μm (alloy composition: Fe _77.5 Si _7.5 B ₁₅ , between two 25 μm thick polyethylene terephthalate (PET) films provided with an acrylic adhesive was used.
A label as shown in FIG. 1 was prototyped with a subscript in atomic%). That is, as shown in FIG. 5, the top tape 2 is a 25 μm thick PET film coated with an acrylic adhesive (PAT-1 type, manufactured by FSK) 4 at a thickness of 25 μm, and the bottom tape 3 is thick. 20 μm polypropylene film with acrylic adhesive (JHL-2359
Type, manufactured by Nihon Fuller Co., Ltd.) with a thickness of 25 μm, the release tape 6 of the bottom tape is made of siliconized paper with a thickness of 70 μm, and is placed opposite the wire nip roller 11 coated with hard rubber. The opposite roller 12 has a diameter of 81.73 mm, and the opposite roller 16 facing the tape nip roller 15 has a diameter of 90 mm.
By rotating the opposing rollers at the same number of rotations, the ratio of the wire feeding speed to the tape feeding speed is 89: (95
+3).

Further, in the wire cutting station 20, two cutting blades 21 are attached to the wire cutting roller 18 having a diameter of 62 mm, and in the die cutting station 24, a die cutting roller having a diameter of 62 mm is used to perform label cutting twice for each round of the roller. It was conducted. Under the above conditions, the cut wire is slid between the wire cutting stations to produce a label with a width of 10 mm and a length of 95 mm.
mm wires were located 3 mm inside each from both ends of the label. When the label sticking work was carried out on the 1 million prototype labels obtained in this way at the store where the article monitoring system is installed, there was a problem that the wire in the label was caught on a finger or nail, or caught on clothes. Did not occur at all.

[0016]

EFFECTS OF THE INVENTION Since the label of the present invention has the above-mentioned constitution, it causes a problem that a conventional label is stuck to an item, such as a finger or the like, and the label is peeled from the item when it is caught on clothes. It is extremely safe in handling and does not cause any problems such as accidents.
