Description

  The present invention relates to a braille label.

  There is known a method of attaching a Braille label for the purpose of having a visually impaired person who has picked up various products read the product information in Braille. In this method, braille labels indicating product information and the like are affixed to the surface of an off-the-shelf product or an off-the-shelf container, instead of forming braille directly on the surface of the product or its container. With this method, it is only necessary to attach a Braille label to a product manufactured for a general customer or its container later, and thus there are advantages of simplicity and cost reduction.

  For example, Patent Document 1 below discloses a Braille label detection mechanism that can reliably detect a Braille label without damaging the Braille label.

  When creating a Braille label, for example, individual points of the Braille may be formed by printing ink that rises when cured after printing. In this case, some points may not be formed due to a mistake in the printing operation. In addition, mistakes may be made in which an incorrect Braille label is affixed to the product.

  When such an error occurs, if an inspector employs an inspection system in which the inspector examines Braille and finds an error, the inspector must acquire accurate Braille knowledge. However, at present, the percentage of healthy people who have acquired braille knowledge is low.

  Therefore, there is a need for a system that inspects braille labels with an inspection device rather than a human inspection. In addition, Braille labels suitable for such inspection methods need to be developed. However, these problems are not taken into consideration in the conventional braille label.

  Therefore, a problem to be solved by the present invention is to provide a Braille label suitable for Braille inspection performed by an inspection apparatus.

Means for Solving the Problems and Effects of the Invention

In order to solve the above-described problems, a Braille label according to the present invention includes a label portion formed of a transparent material , a fluorescent component having a fluorescence action on the surface of the label portion under a predetermined wavelength light, and a transparent ink. and braille portion formed by raised with a mixture of, consist, mixing ratio in said mixture of said fluorescent component, the Braille portion when said predetermined wavelength light is irradiated on the Braille portion for having a fluorescent effect The ratio is equal to or higher than the first ratio, which is the lower limit ratio, and is equal to or lower than the second ratio, which is the upper limit ratio such that the mixture of the fluorescent component and the ink has transparency .

  Thereby, in the Braille label according to the present invention, the Braille portion has a fluorescent action under the light of a predetermined wavelength, so that the Braille image is read by irradiating the light of the predetermined wavelength to check whether there is a mistake in the Braille. Can do. Therefore, it is possible to inspect Braille with high accuracy by the apparatus without requiring human inspection that requires the inspector to know Braille. That is, a Braille label suitable for detecting an error in Braille by the apparatus can be realized.

  Further, the Braille portion may be formed by mixing and printing a component for raising the Braille portion and a component having a fluorescent action under the predetermined wavelength light.

  As a result, it has a fluorescent action under a predetermined wavelength light by a simple method of printing by mixing a component for raising the Braille part and a component having a fluorescent action under a predetermined wavelength light. Braille can be formed. Therefore, a Braille label having a performance capable of detecting a Braille error by the apparatus can be realized. Furthermore, the component for forming Braille and the component having fluorescence action under the predetermined wavelength light are mixed and the Braille is formed by printing. For example, after the Braille is formed, the function of emitting light with the predetermined wavelength is given. Unlike the above, there is an effect that it is possible to form Braille and give the Braille a function of emitting light with a predetermined wavelength light in one printing operation.

  The predetermined wavelength light may be black light, and the component having a fluorescence action under the predetermined wavelength light may be a component that emits fluorescence when irradiated with the black light.

  As a result, the predetermined wavelength light is black light, and the fluorescent component under the predetermined wavelength light is a component that emits fluorescence when irradiated with black light. Inspection can be realized easily. In addition, components that emit fluorescence when irradiated with black light have been widely used so far and can be used easily.

  Embodiments of the present invention will be described below with reference to the drawings. First, FIG. 1 is a diagram showing an embodiment of a braille label 1 of the present invention.

  The braille label 1 includes a braille portion 2 and a label portion 3. The Braille portion 2 is formed by raising individual points of Braille on the surface of the label portion 3. The individual points in Braille are formed by printing (screen printing) ink in which the black light emitting component 21 is mixed with the ultraviolet curable ink 20. The braille part 2 and the label part 3 are both transparent under visible light. The label part 3 may be made of a transparent resin, for example.

  The braille label 1 is affixed to the surface of the article 40. The article 40 may be, for example, a product or a packaging container that stores the product. It is assumed that a character part 41 indicating a product name, product information, etc. is printed on the article 40. What is necessary is just to let the meaning content of the Braille of the Braille label 1 be the product information of the article | item 40, for example. As described above, the braille label 1 has both the braille portion 2 and the label portion 3 transparent, so that no matter where the braille label 1 is affixed to the article 40, a healthy person cannot read the character portion 41 below the braille label 1. Not. The character part 41 may include not only characters but also images.

  The ultraviolet curable ink 20 is an ink that rapidly cures when irradiated with ultraviolet rays after printing, and is suitable for printing characters and images that rise from the paper surface. Therefore, the ultraviolet curable ink 20 is widely used when forming braille by printing. In FIG. 1, when only the ultraviolet curable ink 20 is printed, it is colorless and transparent after curing.

  Further, the black light emitting component 21 refers to a component having a property of emitting fluorescence (or emitting light or developing color) when irradiated with light called black light. In general, black light refers to ultraviolet light having a dominant wavelength of 365 nanometers. As the black light emitting component 21, for example, a material generally called a black light paint or a black light pigment may be used. Blacklight paints and blacklight pigments are widely used and are easily available.

  If the distribution ratio of the black light emitting component 21 with respect to the entire ink (the total of the ultraviolet curable ink 20 and the black light emitting component 21) is less than 5%, it is found that sufficient light is not emitted in the inspection described later. ing. Therefore, the distribution ratio of the black light emitting component 21 to the whole ink is preferably 5% or more. Further, it has been found that the transparency of the braille portion 2 is impaired when the distribution ratio of the black light emitting component 21 to the whole ink is higher than 10%. Therefore, the distribution ratio of the black light emitting component 21 to the entire ink is preferably 10% or less.

  FIG. 2 shows an inspection apparatus 10 for inspecting whether the braille printed on the braille label 1 is correct, and an inspection method using the inspection apparatus 10. The inspection apparatus 10 includes a mounting table 11, black light irradiation units 12 and 13, an imaging unit 14, and an analysis unit 15. The photographing unit 14 may be a CCD camera, for example.

  The analysis unit 15 has a computer structure, and includes a CPU 16 for information processing, a memory 17 for storing various information, and a display unit 18 having a display function. It is assumed that a regular Braille image 50 (regular Braille image) is stored in the memory 17.

  As shown in FIG. 2, the article 40 may be placed on the placing table 11. Then, the black light 30 is irradiated to the braille label 1 attached to the article 40 by the black light irradiation units 12 and 13. As described above, the fluorescence 31 is emitted from the Braille portion 2 including the black light emission component 21 as described above. A Braille image formed by the fluorescence 31 is photographed by the photographing unit 14. The braille image photographed by the photographing unit 14 is sent to the analysis unit 15, and the analysis unit 15 collates with the regular braille image 50.

  When a part of the Braille part 2 is missing due to an error in printing the Braille part 2 or when an incorrect Braille label 1 is attached due to an error during the pasting operation, the image is taken by the photographing part 14. The image and the regular braille image 50 do not match. Therefore, it is determined whether or not there is a missing Braille portion 2 and whether or not the wrong Braille label 1 is attached depending on whether or not it matches the regular Braille image 50. The discrimination result is displayed on the display unit 18. As a result, the user can know the determination result, so that it is possible to deal with a Braille printing error or a Braille label affixing error.

  In the said Example, the ultraviolet curable ink 20 is a component for raising and forming a braille part. The black light emitting component 21 is a component having a fluorescent action under light of a predetermined wavelength, and a component that emits fluorescence when irradiated with black light.

  In the above-described embodiment, the Braille portion 2 and the label portion 3 in the Braille label 1 are both transparent under visible light. However, the present invention is not limited to this, and the Braille portion 2 and the label portion 3 may be opaque. This is suitable for situations where the Braille label 1 does not need to be transparent, for example, when there is no character to be read in the part to which the Braille label 1 of the article 40 is attached, and the Braille portion 2 and the label portion 3 are made transparent. Can be saved.

  When the label part 3 may be opaque, the label part 3 may be made of an opaque resin, for example, and the degree of freedom in material selection is increased. When the braille portion 2 may be opaque, the distribution ratio of the black light emitting component 21 to the entire ink can be increased (to 10% or more). Thereby, the degree of light emission of the braille part 2 when irradiated with black light can be increased. Therefore, the accuracy of the Braille inspection can be improved, and the case where there is a missing Braille portion 2 or the case where the wrong Braille label 1 is affixed can be accurately detected.

The figure which shows embodiment of the braille label of this invention. The figure which shows the inspection method of a braille label.
