Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a detection label that can be easily printed, stamped, etc. on its surface and that can detect metal or magnetic material. By laminating a metal layer or a magnetic layer separately or by laminating these two layers together on a paper layer that is easy to clean, the contents can be displayed at all times during use and cannot be judged visually. Even in the Yohiko state, it can be detected and identified electrically or magnetically.

One of the conventional marking methods is a labeling method, which is widely used for the following reasons.

1) Various adherends, such as metals, glass, ceramics, resins,
Can be attached to wood, paper, etc.

11) Depending on the adherend, the label can be easily peeled off.

111) Various symbols, characters, patterns, etc. can be added to the surface of the label in advance by printing, stamping, etc.

i■) Can be applied even if the adherend is a curved surface.

(2) Since the label can be attached so as to protrude from the adherend, the label can be identified even if the adherend is stacked.

For this reason, even in the marking method by label pasting, which is widely used, if the label pasting position shifts, the label will not pass through the detection unit, making re-detection impossible. If labeling is used to identify defective products, manufacturing problems may easily occur, and if the attached product is further laminated, packaged, etc. after labeling, If visual judgment becomes difficult, this will cause inconvenience.

The present invention has been made in view of these points, and the upper layer is made of paper waste that is easy to print or stamp, and the lower layer is a metal layer or magnetic layer that can detect metal or magnetism, and an adhesive layer. Consisting of 3 layers, paper layer, metal layer 5
It is a detection label that consists of four layers: a magnetic layer or paper layer, a magnetic layer, a metal layer, and an adhesive layer.It is a detection label that can be electrically and magnetically detected after being attached to the adhered object. be.

Paper, which is used as a material for labels, is easy to print and stamp, and is a non-magnetic and insulating material. As the metal layer, aluminum foil, copper foil, etc. are widely used, and these are conductive and nonmagnetic materials. The magnetic layer is made of iron oxide, which is an insulator but has magnetism.

Hereinafter, five embodiments of the present invention will be described with reference to the drawings. The label (A) in Fig. 1 consists of three layers from the top: the paper layer (a), the metal layer (b), and the adhesive layer (d).
From above, the paper layer (a), the magnetic layer (C), and the adhesive layer (d). , an adhesive layer (d), or the magnetic layer (c) and metal layer (b) are reversed.

Such a label (Al) is attached to a strip-shaped mount (1) with its adhesive layer (d) and rolled up.

Figures 5 and 6 each show the state of use of the label (A), and the surface of the label (A,) contains symbols and letters indicating the adherend or display area.

It is printed or stamped as a pattern or the like and displayed (2).

The item shown in Figure 5 (a) is attached to the package (3), the item shown in (b) is attached to the cylindrical object (4), and the item shown in (c) is attached to the package (3).
It has been pasted on the plate-shaped body (5).

In addition, the one shown in Figure 6 (a) is a sheet-like material (6) with the label (4) sticking out and pasted on the necessary items, and these are stacked, and the one shown in (b) is In each web (7) for printing, coating, laminating, etc., a web (7) is wound around which the contents are displayed in a protruding manner at the position of the defective part during the process.

Although not shown, the adherend with the label attached may be wrapped in aluminum foil or other materials.

As explained above, the label according to the present invention is made of paper that is easy to print and stamp on the surface layer, so it can always display the contents, and whether the adhered material is metal, glass, ceramics, resin, wood, paper, etc. Even if the surface to be adhered is curved, it can be applied well. Moreover, since a metal layer and a magnetic layer are interposed between the paper layer and the adhesive layer, either separately or together, it is possible to detect metal even if it cannot be determined visually. It can be easily detected and identified electrically or magnetically using a magnetic detector or magnetic detector.

Particularly when the label-attached item is packaged with aluminum foil or other materials, the presence of the label-attached item with a magnetic layer can be easily detected from the outside using a magnetic detector.

If the adherend is a conductive metal and non-magnetic material, a label with a magnetic layer interposed therebetween, and if the adherend is a non-magnetic material such as a magnetic card or magnetic tape, a label with a metal layer interposed is used. By using each, detection and identification can be performed using a magnetic detector or a metal detector.

If the deposit is made of something other than metal or magnetic material, it may have either a metal layer or a magnetic layer 5 or both.

In addition, when attaching a label so that it protrudes from the object, an adhesive layer is not formed on the protruding part to prevent it from adhering to other objects, and the label does not need to be peeled off again. , avoid forming an adhesive layer on one end.

In short, the label according to the present invention has a paper layer on the surface layer that is easy to print, stamp, etc., and a metal layer or a magnetic layer between this paper layer and a lower adhesive layer, or a metal layer or a magnetic layer. Since the label has two layers interposed together, it is possible to always display symbols, letters, patterns, etc. representing the contents on the surface of the label, and the position where the label is attached cannot be visually determined. Even if there is, it can be easily detected and identified with a metal or magnetic detector.

Note that information that cannot be identified from the outside can be added to a label with a magnetic layer interposed therebetween.
