Description

  The present invention relates to a non-contact type data receiving / transmitting body capable of receiving information from outside using an electromagnetic wave as a medium, and transmitting information to the outside, such as an information recording medium for RFID (Radio Frequency IDentification). More particularly, the present invention relates to a non-contact type data receiving / transmitting body that can be satisfactorily adhered to a cubic curved surface of a gas cylinder main body and a gas cylinder including the same.

Generally, a fiber reinforced plastic composite container is used as a lightweight high-pressure gas cylinder filled with medical oxygen or the like.
For the management of such a high pressure gas cylinder, a bar code label or the like is used.
The bar code label for the gas cylinder displays the management number, product number, filling gas name, gas filling date, etc. of the gas cylinder.

Since gas cylinders are often installed outdoors, barcodes become dirty or deteriorated when exposed to direct sunlight, wet with rain dew, or exposed to exhaust gas, shortening the life of barcode labels, The barcode reading accuracy could be adversely affected.
Therefore, a technique for completely covering the barcode label with a protective sheet is disclosed (for example, see Patent Document 1).

Next, an embodiment of the gas cylinder of the present invention will be described with reference to FIGS. 2 and 3, and a method of using the non-contact type data receiving / transmitting body 10 will be described.
FIG. 2 is a schematic perspective view showing an embodiment of the gas cylinder of the present invention. FIG. 3 is a schematic cross-sectional view showing a non-contact type data receiving / transmitting body attached to the surface of the gas cylinder main body.
The gas cylinder 20 of this embodiment is schematically configured by a gas cylinder main body 21 filled with high-pressure gas and a non-contact type data receiving / transmitting body 10 attached to the gas cylinder main body 21.

  The non-contact type data transmitter / receiver 10 is attached via the adhesive layer 12 so that its longitudinal direction extends in a direction perpendicular to the longitudinal direction of the gas cylinder main body 21 along the tertiary curved surface 21a of the gas cylinder main body 21. Has been. That is, the non-contact type data transmitting / receiving body 10 is adhered along the cubic curved surface 21 a of the gas cylinder main body 21 with the adhesive layer 12 and the magnetic layer 15 inside.

The cubic curved surface 21a of the gas cylinder main body 21 is a so-called shoulder portion between the neck portion 21b and the trunk portion 21c.
In the non-contact type data transmitting / receiving body 10, the adhesive layer 12 and the magnetic layer 15 are brought into contact with the tertiary curved surface 21 a of the gas cylinder main body 21, and the base material 11 and the adhesive layer 12 are formed along the tertiary curved surface 21 a of the gas cylinder main body 21. It is stuck so that wrinkles do not occur while extending the outer edge little by little.

  Further, as shown in FIG. 3, the non-contact type data receiving / transmitting body 10 attached to the cubic curved surface 21 a of the gas cylinder main body 21 is covered with a transparent coating film 22 and integrated with the gas cylinder main body 12.

  As the gas cylinder main body 21, a container liner made of a metal or a non-metallic material is used in which fiber reinforced plastic is wound in multiple layers. Specifically, as the gas cylinder main body 21, a fiber liner such as glass fiber impregnated with resin is helically wound around a container liner made of an aluminum alloy or the like, wound by hoop winding, or further by full wrap winding, and then heated. The resin is cured in a furnace, and after a pressure resistance test, the surface is coated with a clear lacquer or the like.

  As a material for forming the transparent coating film 22, an acrylic resin-based paint is used.

  In this way, the gas cylinder 20 has the non-contact type data receiving / transmitting body 10 using a stretchable base material made of polyurethane resin or polyethylene resin as the base material 11 adhered along the tertiary curved surface 21 a of the gas cylinder main body 21. As a result, the outer edges of the base material 11 and the adhesive layer 12 expand and contract following the shape of the cubic curved surface 21a, so that the non-contact type data receiving / transmitting body 10 is affixed to the cubic curved surface 21a of the gas cylinder main body 21 thoroughly. It is worn. Therefore, there is no gap between the cubic curved surface 21a of the gas cylinder main body 21 and the non-contact type data receiving / transmitting body 10, and a transparent coating film that covers the non-contact type data receiving / transmitting body 10 is provided. In 22, cracks caused by wrinkles of the non-contact type data receiving / transmitting body 10 do not occur. Therefore, the appearance of the gas cylinder 20 and the weather resistance and chemical resistance derived from the acrylic resin are not impaired. Further, since the antenna 13 and the IC chip 14 of the non-contact type data receiving / transmitting body 10 do not come into contact with outside air or moisture, they can be prevented from being deteriorated due to oxidation or corrosion.

  Note that if wrinkles are generated in the non-contact type data receiving / transmitting body 10 and wrinkles are also generated in the antenna 13, the communication characteristics of the antenna 13 are deteriorated. By sticking the receiving / transmitting body 10 without any defects, the non-contact type data receiving / transmitting body 10 exhibits a sufficient function.

Moreover, since the shapes of the base material 11 and the adhesive layer 12 are substantially elliptical in plan view, the non-contact type data receiving / transmitting body 10 can easily follow the shape of the tertiary curved surface 21a of the gas cylinder main body 21, and the non-contact type The effect of preventing wrinkles from occurring in the data transmitting / receiving body 10 is enhanced.
Further, the rectangular magnetic layer 15 is arranged along the long axes of the base material 11 and the adhesive layer 12 whose longitudinal directions are elliptical, and the respective sides are from the outer edges of the base material 11 and the adhesive layer 12. Since the presence of the antenna 13 and the magnetic layer 15 is reduced from affecting the generation of wrinkles in the non-contact type data receiving / transmitting body 10, the non-contact type data receiving / transmitting body 10 The effect of preventing wrinkles is further increased.

  Further, since the gas cylinder main body 21 filled with the high pressure gas and the non-contact type data receiving / transmitting body 10 are integrated in the gas cylinder 20, the management number, product number, filling gas name, gas filling date, etc. of the gas cylinder are indicated. It cannot be easily tampered with and management safety is improved. Furthermore, when rewriting the type of filling gas or the date when gas is newly filled, it is only necessary to write information to the IC chip 14 without replacing the non-contact type data receiving / transmitting body 10. Since it is possible to save the trouble of replacing a new label like a barcode label, the management cost can be reduced.
