Description

[Technical Field]

[0001] The present invention relates to an age display label, and more particularly to a display label that allows a user to visually recognize how many years have passed since the relevant medical equipment was installed there. [Background technology]

[0002] To ensure safety and stability, some types of equipment are replaced after a certain period of time has passed since installation, regardless of whether they are broken or not. This is often the case with equipment installed in facilities related to social infrastructure such as railways, roads, electricity, and water supply. [Prior art documents] [Patent documents]

[0004] [Non-Patent Document 1] none Summary of the Invention [Problem to be solved by the invention]

[0005] In this case, the period since the equipment was installed is often measured in years, and can sometimes be as long as 10 years or more. Furthermore, many of the equipment in question are installed in locations that are difficult to access. Furthermore, the number of pieces of equipment involved is often enormous.

[0006] It may seem that if a label stating the installation date is attached to the equipment, it will be easy to know when it needs to be replaced, but when there is a huge number of pieces of equipment and they are installed in locations that are difficult to access, labels stating the installation date are not an efficient way to deal with the situation.

[0007] In particular, electrical equipment on railways requires regular replacement after a certain period of time has passed, but most of this equipment is installed on poles or overhead wires, making it difficult to access. Having to approach each piece of equipment just to check the installation date significantly hinders the efficiency of the overall replacement work. Furthermore, in the case of labels that list the installation date, the date must be read one by one, and it is not possible to tell the number of years that have passed since installation at a glance, which also makes the work extremely inefficient.

[0008] In view of the difficulty of knowing how long a piece of equipment has been in use due to periodic replacement etc., the inventors have conducted extensive research to find a way to make this information easily known. As a result, they have succeeded in developing a convenient label that displays the number of years that have passed since the equipment was installed, allowing users to easily know at a glance how long the equipment has been in use, from several years to over ten years, and they propose this invention here. [Means for solving the problem]

[0009] The above-mentioned problem is solved by forming a color change part, which is colored so that the hue changes with the passage of time, and a hue comparison part, which is colored in the same hue as the hue of the hue change part after a preset number of years have passed, adjacent to each other on the surface of a film-like substrate, and by pasting a transparent hue change prevention film, which prevents the hue from changing with the passage of time, on the surface of the hue comparison part to constitute an elapsed age display label. [Effects of the Invention]

[0010] It is used by being stuck on equipment for which the number of years that have passed since installation is to be known, and as the number of years passes after installation, the hue of the hue changing part changes due to the influence of ultraviolet rays, wind and rain, but if the hue of the hue comparison part, which displays the hue after a preset period of time, matches the hue of the hue changing part, it is determined that the preset number of years of installation has passed.

[0011] In other words, the number of years since the installation of the target equipment can be determined by the match between the hues of the hue change section and the hue comparison section, and the number of years since the installation can be determined visually and easily with just a glance.It is also possible to efficiently detect equipment that is difficult to approach, such as equipment on poles or overhead lines, in an assembly line manner, and has the excellent effect of contributing to the overall efficiency of inspection and replacement work of various types of equipment.

DETAILED DESCRIPTION OF THE INVENTION

[0013] The greatest feature of this device is that a hue change section, which is colored so that its hue changes over time, and a hue comparison section, which is colored in the same hue as the hue of the hue change section after a preset number of years have passed, are formed adjacent to each other on a film-like substrate, and the number of years that have passed can be determined by the agreement of the hues of the hue change section and the hue comparison section. [Example]

[0014] FIG. 1 is a plan view of one embodiment of the elapsed years display label of this invention, FIG. 2 is a cross-sectional view taken along the line AA in FIG. 1, and FIG. 4 is a plan view showing the state after the set number of years has passed. In the figures, 1 is a substrate made of a film-like material, which has a circular, flat shape and has an adhesive layer 2 formed on the back so that it can be attached to the equipment to be used.

[0015] In this embodiment, the substrate 1 is made of a film material known as PET paper, which is made by stretching polyethylene terephthalate resin into a film. PET paper is strong and durable, and its surface is easy to print on, making it the ideal material for the substrate 1 of the present invention.

[0016] Then, in the center of the front surface of this disk-shaped substrate 1, a disk-shaped hue-changing portion 3 is formed, which is colored concentrically with a color that changes hue over time, as shown in Fig. 1. In the embodiment shown in Figs. 1 and 2, the hue-changing portion 3 is formed by adhering a disk-shaped piece of PET paper 6, on the surface of which the hue-changing portion 3 is printed, to the substrate 1, but as shown in Fig. 3, the hue-changing portion 3 may also be formed by applying paint directly to the surface of the substrate 1.

[0017] Browns and reds, which tend to change over time, are preferred as the hues applied to the hue-changing portion 3. The change in hue over time occurs as a result of the pigments that make up the hue fading due to exposure to ultraviolet rays, wind, and rain.

[0018] Furthermore, on the front surface of the substrate 1, a hue comparison section 4 is formed concentrically around the hue change section 3, and has a donut-shaped planar shape that is pre-painted with the same hue as the hue of the hue change section 3 after a preset number of years have passed.

[0019] The state of change in hue of the hue-changing portion 3 after a certain number of years, such as 5 years, 10 years, or 15 years, can be easily determined by using an existing weather resistance tester. Therefore, the hue comparison section 4 can be formed by selecting a paint with a Munsell number corresponding to the hue of the hue change section 3 after a desired number of years, for example, five years, has passed, and applying this paint to the surface of the hue comparison section 4.

[0020] Furthermore, a transparent hue change prevention film 5 that prevents the hue from changing over time is attached to the surface of this hue comparison section 4. The change in hue is a phenomenon that occurs when exposed to ultraviolet rays and wind and rain, so a transparent polyester or acrylic film that is difficult for ultraviolet rays to pass through and has excellent weather resistance can be suitably used as this hue change prevention film 5.

[0021] 1 to 4, the hue change portion 3 and the hue comparison portion 4 are arranged concentrically, but as shown in Fig. 5, the rectangular hue change portion 3 and the hue comparison portion 4 may be arranged adjacent to each other on the surface of a rectangular substrate 1. In this embodiment, the hue change portion 3 is formed by adhering a piece of PET paper 6 with the hue change portion 3 printed on its surface to the substrate 1, as shown in Fig. 6, but the hue change portion 3 may also be formed by applying paint directly to the surface of the substrate 1, as shown in Fig. 7.

[0022] Furthermore, as shown in Figure 8, multiple hue comparison units 4... may be arranged, such as a hue comparison unit 4a that matches the hue after 5 years and a hue comparison unit 4b that matches the hue after 10 years.

[0023] This embodiment has the above-described configuration and is intended for use by being affixed to equipment for which the number of years since installation is desired to be known. As time passes after installation, the hue of the hue change section 3 changes due to the effects of ultraviolet rays, wind and rain. As shown in Figure 4, if the hue of the hue comparison section 4, which displays the hue after a preset period of time, matches the hue of the hue change section 3, it is determined that the equipment has been installed for the preset number of years. In other words, the number of years since the installation of the target equipment is known by the match between the hues of the hue change section 3 and the hue comparison section 4, and the number of years since the installation can be easily known by just a glance.It is also possible to efficiently detect equipment that is difficult to approach, such as equipment on poles or overhead lines, in an assembly line manner, and has the excellent effect of contributing to the overall efficiency of inspection and replacement work of various types of equipment. [Industrial Applicability]

[0024] It can be used in all industrial fields, as well as in social infrastructure projects such as railways, electricity, roads, and waterworks. [Explanation of symbols]
