Description

  The present invention relates to a nameplate.

  A metal plate engraved with letters and symbols by processing is known. Moreover, the colored layer laminated | stacked on the metal plate by laser processing can be removed partially, and the metal plate provided with functions, such as a nameplate and a scale plate excellent in the visibility of a character and a symbol, can be manufactured. For example, in Patent Document 1, a colored layer of a different color is laminated, and the upper colored layer is partially removed with a laser to expose the lower colored layer, thereby exposing according to the shape of the removed portion. Disclosed is a method for forming a layer color display pattern on a scale plate.

Japanese Patent Laid-Open No. 7-139972

  In the scale plate described in Patent Document 1, the thickness of each colored layer is small. Therefore, good color development cannot be achieved, and as a result, there is a problem that the visibility of a display pattern such as a scale, characters, or symbols is low.

  Further, since each colored layer is thin, high accuracy is required during laser processing.

  The present invention has been made in view of the above circumstances, and an object thereof is to provide a nameplate having high visibility and easy processing.

In order to achieve the above purpose, the nameplate according to the present invention is:
A first layer in contact with one side of the substrate;
A second layer formed on the first layer;
A third layer formed on the second layer,
The color of the first layer is different from the color of the second layer,
The third layer has translucency,
The first layer is thicker than the second layer and the third layer,
A part of the first layer is exposed in a shape representing a symbol.

  The nameplate according to the present invention has high visibility.

It is a top view of the nameplate which concerns on embodiment. (A) is the sectional view on the AA line of the nameplate of FIG. 1, (B) is the BB sectional view of the nameplate of FIG. It is sectional drawing of the nameplate which concerns on another embodiment.

  Hereinafter, the nameplate 1 which concerns on one embodiment of this invention is demonstrated with reference to drawings.

  As shown in FIG. 1, the nameplate 1 has an undercoat layer 30 exposed in a shape corresponding to a pattern (characters, symbols, figures, etc.) to be displayed in a surface 11 of a specific color that covers almost the entire surface. 30 exposed portions are visible as symbols.

  2A is a cross-sectional view taken along the line AA of the nameplate 1 in FIG. 1, and FIG. 2B is a cross-sectional view taken along the line BB of the nameplate 1 in FIG. In FIG. 2, the vertical length (thickness) of the nameplate 1 is emphasized in order to facilitate understanding of the device.

  As shown in FIG. 2 (A), the nameplate 1 has an aluminum plate 20, an undercoat layer 30, an intermediate coat layer 40, and an overcoat layer 50 from the bottom (the back surface 12 side) to the top (the front surface 11 side). It has a stacked configuration. The undercoat layer 30 is thicker than the intermediate coat layer 40 and the overcoat layer 50.

  The aluminum plate 20 is an aluminum plate material, and has a thickness of about 20 μm in the present embodiment. The aluminum plate 20 is a substrate of the nameplate 1 and supports the layers 30, 40 and 50 formed (laminated) thereon.

  The undercoat layer 30 is made of a black acrylic resin and is formed on the aluminum plate 20 to a thickness of about 40 μm.

  The intermediate coating layer 40 is formed from a silver-white acrylic resin, and is formed on the undercoat layer 30 to a thickness of about 30 μm.

  The topcoat layer 50 is formed from an acrylic resin, and is formed on the intermediate coat layer 40 to a thickness of about 10 μm. The topcoat layer 50 has translucency and is thinner than the intermediate coat layer 40 in order to make the nameplate 1 glossy while making the intermediate coat layer 40 visible. In the present embodiment, the topcoat layer 50 is transparent.

  The undercoat layer 30, the intermediate coat layer 40, and the overcoat layer 50 correspond to examples of the first layer, the second layer, and the third layer, respectively, in the claims.

  As shown in FIGS. 1 and 2, portions of the overcoat layer 50 and the intermediate coat layer 40 corresponding to characters, symbols, graphics, etc. displayed on the nameplate 1 have been removed, and the undercoat layer 30 is in the middle. The coating layer 40 and the top coating layer 50 are exposed without being covered. That is, the nameplate 1 includes a recess having the undercoat layer 30 as a bottom, and the recess opens in a direction perpendicular to the aluminum plate 20.

  By doing in this way, in the area | region where the dent of the nameplate 1 was formed, the black undercoat 30 is exposed and visually recognized. On the other hand, in a region where the undercoat layer 30 is not exposed, the silver-white intermediate coat layer 40 is visually recognized through the transparent overcoat layer 50. Since the contrast between the black of the undercoat layer 30 and the silver white of the intermediate coat layer 40 is high, the nameplate 1 has high visibility.

  Moreover, in this Embodiment, since the aluminum plate 20 is used as a base material (metal plate), the nameplate 1 is lightweight compared with other metals, such as iron and stainless steel.

  Further, in the present embodiment, an overcoat layer 50 is formed on the undercoat layer 30 and the intermediate coat layer 40. By doing in this way, the nameplate 1 is equipped with abrasion resistance and a weather resistance.

Hereinafter, the manufacturing method of the nameplate 1 is demonstrated.
First, in order to ensure the adhesion and uniformity of the paint to the surface of the aluminum plate 20, preparation processing such as polishing and degreasing is performed as necessary.

  Next, a black paint containing a thermosetting acrylic resin is applied to one surface of the aluminum plate 20 with a coater to a certain thickness, dried in a drying furnace, and baked (thermosetting) at 140 ° C. for about 20 minutes. And undercoat layer 30 is laminated. At this time, the coating material is applied by a coater so that the thickness after baking is 40 μm.

  Next, a silver-white paint containing a thermosetting acrylic resin is applied to the surface of the undercoat layer 30 to a certain thickness with a coater, dried in a drying furnace, and baked at 140 ° C. for about 20 minutes. The coating layer 40 is laminated. At this time, the coating material is applied by a coater so that the thickness after baking is 30 μm.

  Further, a transparent paint containing a thermosetting acrylic resin is applied to the surface of the intermediate coating layer 40 with a coater to a certain thickness, dried in a drying furnace, and baked at 160 ° C. for about 20 minutes. 50 are stacked. At this time, the coating material is applied by a coater so that the thickness after baking is 10 μm.

  Thereafter, the surface 11 is irradiated with a laser beam having a small beam diameter using a laser processing machine. By scanning with a laser beam according to the shape of characters, symbols, and figures to be displayed, a part of the overcoat layer 50, the intermediate coat layer 40, and the undercoat layer 30 is evaporated and removed. Conditions such as the time and intensity of laser irradiation are set so that the laser beam does not pass through the overcoat layer 50 and the intermediate coat layer 40 but through the undercoat layer 30 and reach the aluminum plate 20. In the present embodiment, since the undercoat layer 30 is thicker than the intermediate coat layer 40 and the overcoat layer 50, the above conditions can be easily satisfied.

  As described above, in the present embodiment, the undercoat layer 30 is black, the intermediate coat layer 40 is silver white, and the overcoat layer 50 is transparent. For this reason, a character, a symbol, a figure, etc. are displayed on the silver white surface by the viewer in black with high contrast. Therefore, the nameplate 1 with high visibility is obtained.

  Further, the undercoat layer 30 is thicker than the intermediate coat layer 40 and the overcoat layer 50, respectively, and is approximately equal to the sum of the thicknesses of the intermediate coat layers 40 and 50, and is 40 μm or more. For this reason, when the intermediate coating layer 40 and the top coating layer 50 are removed by laser, the laser is easily controlled, and the dent does not reach the undercoat layer 30 or the surface of the aluminum plate 20 is removed by removing the undercoat layer 30. Can be prevented from being exposed.

  Further, by narrowing the beam diameter of the laser beam used in the manufacturing process of the name plate 1, fine characters, figures and symbols can be formed on the name plate 1.

  In the embodiment, the baking temperature and time of the undercoat layer 30, the intermediate coat layer 40, and the topcoat layer 50 are set to 140 ° C. for 20 minutes, 140 ° C. for 20 minutes, and 160 ° C. for 20 minutes, respectively. Therefore, each layer 30, 40, and 50 can be formed uniformly and firmly.

In addition, this invention is not limited to the said embodiment, A various deformation | transformation is possible.
In the present invention, the first color of the undercoat layer 30 and the second color of the intermediate coat layer 40 are not limited to black and silver white, and may be different. Thereby, a different color with a large contrast can be selected, and a clear and highly visible nameplate can be provided.

  The undercoat layer 30 only needs to be thicker than the intermediate coat layer 40 and the overcoat layer 50, and the specific thickness thereof is arbitrary. From the viewpoint of controllability of removal by laser light, the thickness of the undercoat layer 30 is preferably 40 μm or more and larger than the sum of the thickness of the intermediate coat layer 40 and the thickness of the overcoat layer 50. By having such a thickness relationship, a large margin is ensured, and insufficient removal and overremoval by laser light are prevented. Further, it is desirable that the undercoat layer 30, the intermediate coat layer 40, and the overcoat layer 50 are made of the same material. As a result, the removal rate with respect to the energy of the laser beam becomes constant, and control becomes easy.

  In order to obtain a high-contrast nameplate, a method of directly irradiating the aluminum plate 20 with laser light to form a recess and filling the recess with paint is also conceivable. However, this method requires a step of removing excess paint with an organic solvent. On the other hand, in the manufacturing method according to the present embodiment, there is no need to remove the extra paint with an organic solvent after the laser processing step, and therefore, the load on the environment is small. Further, according to the manufacturing method of the present embodiment, since the worker is not exposed to the gas of the organic solvent during the manufacturing process, it is possible to suppress discomfort caused by the odor of the organic solvent. Furthermore, in the manufacturing method of the present embodiment, baking is performed after the coating is applied, so that the adhesion and weather resistance of each layer 30, 40, 50 are higher than in the manufacturing method in which baking is not performed.

  When manufacturing a plurality of small nameplates 1, after forming a plate including a plurality of nameplates 1, the nameplate 1 may be separated into individual nameplates 1 using, for example, a shearing machine, a laser processing machine, or a saw. . The same applies to the production of the nameplate 1 having an arbitrary shape different from the aluminum plate 20 as a raw material. By doing in this way, since the several nameplate 1 and the nameplate 1 of a different shape can be manufactured at once, the improvement of productivity can be aimed at.

  FIG. 3 is a cross-sectional view of a nameplate 100 according to another embodiment, cut along line BB in FIG. In FIG. 3, the vertical length (thickness) of the nameplate 100 is emphasized in order to facilitate understanding of the device.

As shown in FIG. 3, the height of the aluminum plate 120 may vary depending on the location due to roughness and distortion. In such a case, the undercoat layer 130 may be formed thicker and the upper layer may be formed after the surface of the undercoat layer 130 is flattened.
Specifically, in the nameplate 100, an undercoat layer 130, an intermediate coat layer 140, and an overcoat layer 150 are formed on the aluminum plate 120 by the same method as the nameplate 1.
Here, the maximum value of the height difference of the surface of the aluminum plate 120 is D. Further, T is the thickness of the undercoat layer 130 in the most concave portion in the direction perpendicular to the aluminum plate 120.
By forming the undercoat layer 130 that is sufficiently thicker than the unevenness of the aluminum plate 120, the unevenness on the surface of the aluminum plate 120 is absorbed, so the surface 111 of the nameplate 100 is flat. Specifically, as shown in FIG. 3, undercoating is performed such that T is larger than the difference (maximum difference D) between the height of the most recessed portion and the height of the most raised portion in the direction perpendicular to the aluminum plate 120. Layer 130 is formed.

In each embodiment, the undercoat layers 30 and 130 are formed of a black paint, but are not limited thereto. For example, the coating itself generated by anodizing the aluminum plates 20 and 120 may be used as the undercoat layers 30 and 130, and a coating is formed by adding another substance such as a paint to a large number of micropores included in the coating. May be used as the undercoat layers 30 and 130.
In each embodiment, aluminum plates 20 and 120 are used as the metal plate as the base material. However, the present invention is not limited to this, and plate materials made of other materials such as stainless steel, brass, and plastic are used. Also good.

  Moreover, it is not limited to the case where the above-mentioned structure itself is used as a nameplate, The above-mentioned structure may be bonded to another thick plate to form a nameplate.
