Description

[0001] The present invention relates to a braille panel manufacturing apparatus,

[0001] The present invention relates to a braille panel manufacturing apparatus and, more particularly, to a braille panel manufacturing apparatus, in which various engravings for visually impaired persons are pressed in the process of engraving braille on a metal plate to form engraved grooves at the bottom, To a braille panel manufacturing apparatus which is developed to prevent braille from being damaged and to display a braille protruding in a clear and constant shape.

The number of people with disabilities who are physically uncomfortable can be seen around us. The number of people with disabilities is as high as 2,501,112 persons in December 2013 in Korea alone. There are many people with disabilities who are living and working more stable It was possible.

Even if the two legs are inconvenient, they use electric walkers to perform outdoor activities. However, over 250,000 people with visual impairments live in an extremely limited environment, and some have received the sale of some blind guide dogs, Number.

The outside life of a visually impaired person who can not see ahead is almost impossible without the help of others, and even living in the interior is having difficulty.

In 1829, it was introduced by a French blind lover, Louis Brau, that a braille embossing system was introduced in household appliances such as washing machines, which made it possible to read with the touch of a finger. It is preferable to attach a panel displaying Braille characters to various facilities for indoor and outdoor activities.

In this braille panel, when a stamping tool is pressed on the upper surface of the metal plate placed on the lower panel so that a convex braille pattern protrudes on the bottom surface thereof, the braille panel is turned upside down and at the same time, And it was common to manipulate the engraving tool by hand usually.

However, the bottom panel receives a pressing force when the bottom of the metal plate is protruded. When the bracket is made of a rigid material, the braille protrudes unclearly. When the bottom panel is made of a soft material, There is a problem that the portion is bent or projected downward.

The lower ends of both sides of the worktable 11 extend downwardly and are mounted on both sides of the upper surface of the worktable 11 and extend in the forward and backward directions to move in the forward and backward directions;

A moving block 13 mounted on the moving frame 12 and moving in the lateral direction;

An ascending / descending block 15 mounted on the moving block 13 and ascending and descending by a cylinder and having a stamped tool 14 mounted on a lower end thereof;

A metal plate 2 is mounted on an upper surface of the work table 11 and a hemispherical shape is formed so as to insert a braille protrusion formed by a tool 14 engraved on the metal plate 2 A lower panel (3) having a plurality of braille grooves (31) recessed;

And a plurality of metal plate fixtures 4 for pressing and fixing the upper surface of the metal plate 2 mounted on the lower panel 3 along the outer rim of the lower panel 3, .

Conventionally, in order to manufacture a conventional braille panel, there is almost no method in which an operator directly presses the upper surface of the metal plate 2 to form a protrusion for forming braille on the bottom surface. In this case, there is a problem that labor is consumed and productivity is low .

Accordingly, the movable frame 12, the moving block 13, and the ascending / descending block 15 are automatically moved in a predetermined path by the set program to automatically form the braille on the metal plate 2, 2) are cut to form a plurality of braille panels, thereby consuming less manpower and achieving high productivity.

The embossing tool 14 presses the metal plate 2 to form a protrusion on the bottom surface of the metal plate 2. The lower panel 3 supporting the metal plate 2 presses the bottom surface of the metal plate 2, In this case, the braille groove 31 is formed in accordance with the shape of the braille, so that damage to the lower panel 3 is prevented, and the metal plate 2 is inserted into the braille groove 31 formed in a constant shape. As a result, a clear and consistent Braille is formed.

FIG. 4 is a perspective view of a lower panel according to a first enlarged embodiment of the present invention. Braille grooves 31 formed on the upper surface of the lower panel 3 are arranged in a lattice arrangement at equal intervals in the front, The present invention is not limited to these embodiments.

In this embodiment, not only a phrase indicated by a certain braille but also other phrases can be formed by using the same lower panel 3, and a braille character basically expresses consonants or vowels using three vertices and two horizontals So that the braille grooves 31 are formed in the lattice arrangement, so that the metal plate is inserted and inserted by the engraving tool 14 selectively according to the braille.

5 is a perspective view of a lower panel according to a second enlarged embodiment of the present invention, wherein the lower panel 3 has a braille block seating groove 32 formed by recessing a portion except an upper surface frame, A plurality of braille blocks 33 having a rectangular plate shape in which the braille grooves 31 are formed and adjacent to the four corners of the bottom surface and in which the first magnets 331 are embedded are inserted into the braille block seating grooves 32;

The surface of the bracket block 33 which is in close contact with the bottom surface of each braille block 33, And has a separation hole 322. [0100]

In the above embodiment, the braille block 33 may be mounted only on a desired area of the lower panel 3 where the braille groove 31 is formed. If the size of the braille is changed, It is possible to replace the braille block 33 with the braille block 33 formed thereon.

FIG. 6 is a perspective view showing a braille block according to a third enlarged embodiment of the present invention. FIG. 7 is a conceptual view showing a close contact structure of a braille block according to a third enlarged embodiment of the present invention, Shaped magnet 333 having a smaller diameter than the inner diameter of the magnet insertion groove 332 and rotatable inside the magnet insertion groove 332, And the entrance of the magnet insertion groove 332 is closed with a tongue bolt 334. In this embodiment,

In the above embodiment, the sides of the braille block 33 having close contact with each other have a force to be in close contact with each other. It is troublesome and inconvenient to match the polarity of the magnet by inserting the magnet into the four sides of the braille block 33 have.

In this case, when the third magnet 333 of the present invention is made rotatable in the magnet insertion groove 332, if one of them is rotated in the same direction and then the other polarity faces, So that an adhesive force is applied through the bolt 334.

FIG. 8 is a perspective view showing a bottom panel according to a fourth enlarged embodiment of the present invention, FIG. 9 is a conceptual view according to a fourth enlarged embodiment of the present invention, And an insertion portion (35) having an entrance width of the T-shaped groove (34) extended on both sides of the T-shaped groove (34);

The metal plate fixture 4 is in close contact with the side surface of the lower panel 3 and the upper end of the metal plate fixture 4 is further protruded upward from the upper surface of the lower panel 3 and has a T- An insertion protrusion 41 protruding and horizontally moving along the T-shaped groove 34 after being inserted through the insertion portion 35; a bolt 42 vertically installed on the upper surface; A fixing block 43 for pressing and fixing the upper face of the metal plate 2 which is mounted to be bent and extended downward in the inner direction of the lower panel 3 and a nut 44 engaged with the bolt 42, The present invention has been made in view of the above problems.

In the above embodiment, the metal plate fixture 4 presses and fixes the upper surface of the metal plate 2 to be lifted on the upper surface of the lower panel 3. The standard of the metal plate 2 may vary depending on the situation, There is a possibility that the metal plate 2 can not be stably fixed.

The present invention can fix the metal plate 2 at an optimum position even if the size of the metal plate 4 is changed by allowing the metal plate fixture 4 to move along the side surface of the lower panel 3.
