Abstract

PURPOSE:To manufacture a label without damaging fingers or hanging the label to cloth when the label is sticked to an object by holding an amorphous metal fine wire between two tapes, which defines paper or film as a base, at least and making the length of the amorphous metal fine wire shorter than the length of the tape. CONSTITUTION:The length of an amorphous metal fine wire 1 is shorter than the lengths of upper and lower surface tape bases 2 and 3 and the both ends of the amorphous metal fine wire 1 are positioned on the inside rather than the both ends of the tape. This amorphous metal fine wire 1 is sandwiched between the upper and lower surface tape bases 2 and 3, which is composed of the paper or the film, and fixed by an adhesive agent 4. Thus, the label with high safety for handling is obtained without problems that the fingers, etc., are damaged when the label is sticked to the object or that the label is detached from the object by being hung to the cloth, etc.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention is used in a system for preventing theft of goods or articles in retail stores, public facilities, and the like. The present invention relates to an article monitoring label (hereinafter simply referred to as a label) using a thin amorphous metal wire and a method for manufacturing the same.

(Prior Art) It is said that damage caused by items being taken away without permission from retail stores such as department stores and supermarkets, and public facilities such as libraries is increasing year by year. In order to prevent unauthorized removal of these items, so-called theft prevention, a magnetic system is used that attaches a label made of soft magnetic material to each item and detects changes in the magnetic field generated by the soft magnetic material when the nine items pass through a detection area. is applied. Recently, amorphous metal materials have been used as soft magnetic materials for magnetic system labels to improve the sensitivity and reliability of the system, and among them, amorphous metal thin wires are attracting attention (Japanese Patent Application Publication No. Publication number 61-153799).

In the conventional label manufacturing method using this thin amorphous metal wire, it was only possible to manufacture a label in which both ends of the tape and both ends of the thin amorphous metal wire coincided with each other.

That is, in conventional labels, an amorphous metal thin wire is fed between at least two tapes based on paper or film at the same speed as the tape, and an amorphous metal wire is fed in the same length as the tape. Since the label was manufactured by cutting a thin metal wire and continuously processing it into the shape of a label, both ends of the tape and both ends of the thin amorphous metal wire were aligned.

FIG. 5 shows the shape of a conventional label, in which the thin amorphous metal wire 1 and the tape 2 are of the same length,
Furthermore, the ends are completely aligned.

(Problem to be Solved by the Invention) In the above-mentioned label, both ends of the tape and both ends of the thin amorphous metal wire are aligned, so the label is peeled off one by one from the release paper tape for holding the label and the product is removed. When pasting the label by hand, if you press the label with your finger, the thin amorphous metal wire will get stuck in your finger and cause damage to your finger.

There was also the problem that when an item touched clothing, the tip of the thin metal wire would get caught on the clothing, causing the label to peel off. This is because the amorphous metal wire used as a soft magnetic material is
It is a very thin wire with a diameter of 0.1 to 0.15 mm,
Furthermore, it is derived from the fact that it is a needle-like object that is extremely hard and does not bend easily.

Moreover, with conventional label manufacturing methods, it was only possible to manufacture labels in which both ends of the tape coincided with both ends of the amorphous metal thin wire.

(Means for Solving the Problems) The present inventors have conducted extensive studies with the aim of providing a label that does not injure fingers when attached to articles and that does not get caught on clothes, and a method for manufacturing the same. As a result, both ends of the tape base material constituting the product monitoring label were made several mm longer than the thin amorphous metal wire used as the soft magnetic material, and both ends of the thin amorphous metal wire were made with the tape base material of the label constituent material. In addition, this label can be easily and continuously manufactured by applying oil to the thin amorphous metal wire and then feeding the fine amorphous metal wire at a feeding speed slower than the running speed of the tape. The present invention was achieved by discovering that it can be manufactured.

That is, in the first invention, the amorphous metal thin wire is held between at least two tapes made of paper or film as a base material, and the length of the amorphous metal thin wire is longer than the length of the tape. The object of the present invention is to provide an article monitoring label for use in an article taking-out monitoring system, in which both ends of a thin amorphous metal wire are located inside of both ends of the tape.

Further, the second invention is to insert an amorphous metal thin wire between at least two tapes having paper or film as a base material, cut the amorphous metal thin wire to a predetermined length, and then cut the amorphous metal thin wire into a predetermined length.
When cutting out a piece of tape to a predetermined size to produce an item monitoring label for use in an item removal monitoring system, oil is applied to the thin amorphous metal wire, and then the thin amorphous metal wire is cut out at the running speed of the tape. The gist of the present invention is to provide a method for manufacturing an article monitoring label, which is characterized in that the label is supplied at a slower supply speed than the conventional one.

One aspect of the present invention will be explained 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 length of the upper tape base material 2 and the lower tape base material 3 (hereinafter, these will be collectively referred to simply as tape). ) is shorter than the length of the amorphous metal thin wire 1.
It has a structure in which both ends of the tape are located inside of both ends of the tape.

This amorphous metal thin wire l is sandwiched between an upper tape base material 2 and a lower tape base material 3 made of paper or film, and an adhesive 4
is fixed. An adhesive 5 is applied to the back surface of the bottom tape base material 4, and the labels are fixed one by one on release paper 6 at regular intervals. When in use, the label is peeled off from the release paper and affixed to the item.

At this time, the length of the amorphous metal thin wire 1 is as follows.

It varies depending on the magnetic system used for detection, but approximately 30~
100 mm is appropriate, and it is preferable that the length of the amorphous metal thin wire 1 is several mm shorter than the length of the tape 2.3, specifically, about 2 to 10 mm, and
Both ends of the amorphous metal thin wire 1 are 3M from both ends of the tape 2.3
It is preferable to position the inner side by about 1 to 5 mm, specifically, about 1 to 5 mm.

This amorphous metal thin wire 1, as shown in the following manufacturing example,
Since the top tape base material 2 is cut from above, a cutout 7 corresponding to one cut end of the thin amorphous metal wire 1 remains on the top tape base material 2, but the top tape base material 2 is completely cut. The thin amorphous metal wire 1 is covered without being cut, and the end of the thin amorphous metal wire 1 is not exposed on the surface side of the top tape base material 2, so that the label cannot be attached to the article. There are no problems with pasting or catching clothes, etc.

Note that FIGS. 3(a) and 3(b) show another embodiment of the label of the present invention, and FIG. 3(a) shows an amorphous metal wire 1 in close contact with This is a label in which a hard magnetic material 8 having a larger coercive force than the fine metal wire 1 is arranged in a strip shape. This is also a label in which hard magnetic wire 9 having a large coercive force is arranged. These labels are made by magnetizing the hard magnetic material 8.9 with a large coercive force using an appropriate means to apply a bias magnetic field to the thin amorphous metal wire 1 and artificially generate an alarm signal as a used label. It is a type of label that can be lost.

YHJ30-10 (Hitachi Metals M) is used.

Next, a method for manufacturing a label according to the present invention will be explained with reference to the drawings.

FIG. 4 is a schematic process diagram showing an example of manufacturing a label according to the present invention. In FIG. 4, first, an amorphous metal thin wire (hereinafter abbreviated as wire) 1 is supplied from a bobbin 10 to a wire nip station 13 which is composed of a wire nip roller 11 and an opposing roller 12 disposed opposite to this roller. After passing through and being coated with oil by the oiling unit 14, it is sent to a nip station 17, which is comprised of a second nip roller 15 and an opposing roller 16 disposed opposite to this roller. A top tape 2 coated with adhesive 4 is placed on the upper side of the wire 1 at the nip station 1.
On the underside of the wire 1, a lower tape 3 having an adhesive 5 and a release paper 6 on the back side is also supplied to a nip station 17. Nip station 17
The upper tape 2, the lower tape 3, and the wire 1 are combined and sent to a wire cutting station 20 comprising a front wire cutting roller 18 and an opposing roller 19 disposed opposite to this roller. At the wire cutting station, by the cutting blade 21.

The wire 1 is cut together with the top tape 2 and the bottom tape 3.

By changing the circumferential speed between the facing roller 12 of the wire nip station 13 and the facing roller 16 of the nip station 17, the feeding speed of the wire 1 to the top tape 2 and the bottom tape 3 can be slowed down.

At this time, wire 1, top tape 2, and bottom tape 3
It is desirable to select a speed ratio such that the length of the wire 1 is 2 to 10 mm shorter than the lengths of the upper tape 2 and the lower tape 3.

Further, the wire 1 cut at the wire cutting station 20 slides between the upper tape 2 and the lower tape 3 between the nip station 17 and the wire cutting station 20.

As mentioned above, before the wire 1 is cut, it is necessary to apply oil or the like by a suitable means such as the oiling unit 14 in order to improve the sliding between the upper and lower surfaces. The oil used for sliding the wire 1 may be a commercially available lubricating oil, but in consideration of rust on the wire 1, it is preferable to add a rust preventive agent.

Next, the top tape 2 and the bottom tape 3 sandwiching the cut wire 1 are sent to a die cutting station 24 consisting of a die cut roller 22 and an opposing roller 23 installed opposite to this roller. 3 is cut out in the shape of a label, leaving the thickness of the release paper 6 intact.

Unnecessary portions of the top tape 2 and bottom tape 3 other than the shape of the label are removed by a scrap removal roller 25.

Labels arranged at regular intervals on the release paper are wound onto a product roll 26.

By doing so, a label as shown in FIG. 1 can be obtained.

(Example) The present invention will be specifically explained below using examples.

Example 1 A wire with a wire diameter of 125 μm (alloy composition: Fetl,
5sit, sB+s+subscript is atomic%)
We made a prototype label as shown in the figure.

That is, as shown in FIG. 4, the top tape 2 is made of acrylic adhesive (FAT
-1 type, made by FSX■ Co., Ltd.) 4 is coated with a thickness of 25 μm, and the bottom tape 3 is a polypropylene film with a thickness of 20 μm, and an acrylic adhesive (JHL-2359 type 9 made by Nippon Fuller ■ Co., Ltd.) is applied to a thickness of 25 μm. Silicone-treated paper with a thickness of 70 μm was used for the release paper 6 of the lower tape, and the diameter of the opposing roller 12 placed opposite the wire nip roller 11 coated with hard rubber was 81 μm.
．． By setting the diameter of the opposing roller 16 opposite to the tape nip roller 15 to 73 mm and 90 mm, and rotating these two opposing rollers at the same rotation speed, the ratio of wire feeding speed to tape feeding speed is 89: (95+3).
tailored to.

Furthermore, at wire cutting station 20.

Two cutting blades 21 are attached to a wire cut roller 18 with a diameter of 62 mm, and at the die cutting station 24,
A die-cut roller with a diameter of 62 mm was used to cut out the label twice per rotation of the roller.

According to the above conditions, the cut wire can be cut into a width of 10 mm by sliding between the wire cutting stations.
, a 95 mm long label was produced with 89 mm long wires located 3 mm inward from each end of the label.

The 1 million prototype labels obtained in this way were pasted on at a store that had installed a product monitoring system.

The wire inside the label may get caught on your finger or nail.

Also, there were no problems with it getting caught on clothing.

(Effects of the Invention) Since the label of the present invention has the above-described configuration, there are problems such as injuring fingers when pasting a conventional label on an item, and the possibility that the label may get caught on clothing or the like and cause the label to damage the item. It is extremely safe to handle as it does not cause problems such as peeling off.

Furthermore, according to the method for manufacturing labels of the present invention, the above-mentioned labels with extremely high handling safety can be manufactured easily, continuously, and at low cost.
