[Industrial applications]

 The present invention relates to a nameplate material on which a name is engraved in order to create a nameplate to be attached to various devices, and more particularly, to a nameplate material for engraving a name on the back side.

[0002]

[Prior art]

 Conventionally, the nameplate material 2 for back engraving as described above is one in which a light-shielding paint layer 6 is formed on the back surface of a transparent acrylic plate 4 of a required size as shown in FIG. 6, for example. . The nameplate material 2 for such a back engraving is manufactured as follows, for example. First, as shown in FIG. 7, a light-shielding paint such as a white paint is applied to the entire rear surface of a rectangular transparent acrylic plate 8 having a relatively large size to form a paint layer 10. Next, the acrylic plate 8 is cut with a saw along the virtual cutting lines 12, 12 ... Along the long side of the acrylic plate 8 into strips 8a. The long sides of these strips 8a are finished with a plane. Finally, the strip-shaped bodies 8a are sawn along the virtual cutting lines 14, 14 ...

As shown in FIG. 9, the name plate materials 2 thus manufactured are arranged and fixed one by one on the vacuum suction table 18 of the engraving machine 16 so that the paint layers 6 are on the upper surface. In FIG. 9, in order to show that the nameplate materials 2 are arranged one by one, the nameplate materials 2 are illustrated as being arranged on the suction table 18 at intervals. The nameplate materials 2 are laid on each other with no space. After being arranged and fixed in this way, a desired character is engraved on the paint layer 6 by moving the cutter portion 20 in the arrow X direction and moving the vacuum suction table 18 in the arrow Y direction. At this time, the engraved letters are reverse letters so that they can be read correctly when viewed from the front side of the acrylic plate 4. After completion of this engraving, the paint layer 6 of the nameplate material 2 is black-painted, for example, by applying black paint, and then unnecessary black paint is wiped off to complete the nameplate.

[0004]

[Problems to be solved by the device]

 In such a name plate material 2, when engraving, one by one must be arranged on the vacuum suction table 18 of the engraving machine 16, and moreover, one by one, the characters are engraved as desired. It had to be inspected, and there was a problem that work efficiency was low.

Such a problem is engraved, blackened, wiped, and inspected in a state where the paint layer 10 is simply formed on the acrylic plate 8 before being formed on each nameplate material 2 as shown in FIG. 7, for example. The problem can be solved by carrying out the above, and then cutting and finishing so that each nameplate material 2 is obtained. However, since only the paint layer 10 is formed on the acrylic plate 8, it is difficult to cut, and a part of the paint layer 10 peels off at the time of cutting, which reduces the commercial value. Occurs.

【Example】

 The name plate material 30 according to this embodiment has a transparent acrylic plate 32 as shown in FIG. The acrylic plate 32 has a rectangular shape having a size of 550 × 700 × 2 mm, for example, and a white paint layer 34 having a thickness of, for example, 30 to 40 μm is formed on the entire back surface thereof.

On the surface of the acrylic plate 32, a plurality of V-shaped grooves 36 are formed parallel to one side thereof. Further, a V-shaped groove 38 is formed so as to be orthogonal to these grooves 36. The distance between the V-shaped grooves 36 and the distance between the V-shaped grooves 36 are selected so that each region defined by the grooves 36, 38 has a desired size of a nameplate material. These V-shaped grooves 36 and 38 are, for example, about 0.7 to 1 mm deep and are formed with an angle θ shown in FIG. 1 of about 35 to 45 degrees.

Further, a V-shaped groove 40 is formed on the back surface of the acrylic plate 32 at the same position as the V-shaped groove 36 provided on the front surface, and similarly at the same position as the V-shaped groove 38. A V-shaped groove 42 is formed in the. These V-shaped grooves 40, 42 have a depth of about 0. 1 mm, the angle φ shown in FIG. 1 is formed to be about 35 to 45 degrees. The paint of the paint layer 34 is peeled off from the places where the V-shaped grooves 40 and 42 are formed.

Such a name plate material is manufactured, for example, as follows. First, as shown in FIG. 2 (a), an acrylic plate 32 is prepared, and the back surface side thereof is roughened so that the paint can be adhered well. As shown in FIG. 2 (b), a paint layer 34 is formed over the entire back surface. Attach it.

Next, positioning holes 44, 44 are formed at predetermined positions at the corners of the acrylic plate 32 symmetrically with respect to the center line of the acrylic plate 32. Then, for example, insert the positioning holes 44, 44 so that the surface side of the acrylic plate 32 faces upward and the positioning columns provided on the cutting machine as shown in FIG. 2 (c). Then, the acrylic plate 32 is positioned and the V-shaped grooves 36 and 38 are cut.

Next, the acrylic plate 32 is turned upside down, that is, the paint layer 34 is on the upper side, and the positioning holes 44, 44 are inserted into the positioning columns. Then, the V-shaped grooves 42 and 44 are cut by operating the cutting machine in the same manner as when cutting the V-shaped grooves 36 and 38. As a result, the V-shaped grooves 36 and 42 and the V-shaped grooves 38 and 44 are formed at the same positions on the front and back of the acrylic plate 32. Although the positioning hole 44 is formed in the acrylic plate 32, a contact may be formed in the cutting machine as shown by the dotted line in FIG. 2C, and this may be used.

The name plate material 30 manufactured as described above is arranged on the vacuum suction table 18 of the engraving machine 16 so that the paint layer 34 is on the upper surface as shown in FIG. Characters are engraved in each unit area with the area divided by 2, 44 as one unit area. This engraving is performed by moving the cutter unit 20 in the X direction and the vacuum suction table 18 in the Y direction.

When the engraving on each unit area is completed, the nameplate material 30 is removed from the vacuum suction table 18, and black paint is applied to each engraved portion of each unit area to carry out inking. After that, unnecessary black paint is wiped off from the surface of the paint layer 34.

Next, as shown in FIG. 4 (a), a double-sided adhesive tape 46 is attached to the paint layer 34 side of the name plate material 30, and the double-sided adhesive tape 46 is provided with streaks 48 along the grooves 40 and 42. Insert and fold the nameplate material 30 along these lines 48. This completes the nameplate.

Since the grooves 42, 44 are provided not only on the front surface side of the nameplate material 30 but also on the back surface side thereof at the same positions as the grooves 36, 38 on the front surface side, they easily break when folded, and The folded surface does not get rough. Moreover, since the coating material is not attached to the grooves 42 and 44 on the rear surface side, the coating material does not peel off.

At the time of folding, as shown in FIG. 5, first, by folding along the grooves 36, 40 corresponding to the short sides of each nameplate, the short sides of each nameplate are arranged in a line. It is difficult to hook each name plate into pieces, and each short side can be hooked easily.

In the above embodiments, the surface side of the acrylic plate was left exposed, but during the work such as engraving, inking, wiping, etc., the surface of the acrylic plate should not be scratched. A thin film mask material may be pressed onto the surface of the acrylic plate. Further, in the above embodiment, the grooves 36 and 38 are formed on the front side of the acrylic plate 32, and the grooves 40 and 42 are formed on the back surface side, respectively. However, for example, only the groove 36 is formed on the front side of the acrylic plate 32. Only the groove 40 may be provided on the back side, only the groove 38 may be provided on the front side of the acrylic plate 32, and only the groove 42 may be provided on the back side.
