The medal polishing apparatus according to 13), wherein a plurality of rotating brushes are arranged in a plurality of rows in the conveying direction above, and a grindstone plate for polishing brush bristles of the rotating brush is placed on the upper ends of the plurality of rotating brushes.

According to the present invention, the rotating brush rotates so that the tip of the bristles of the rotating brush comes into contact with the mesh surface of the mesh body so that the tip of the bristle is bent along the mesh surface. The adhering substance of hair debris is rubbed against the protruding net member to forcibly peel off. Further, the tip of the bristle is inserted into the mesh space of the mesh body, and the tip of the brush bristle is detached from the mesh space as it advances by a predetermined angle, but in the time from the point of insertion into the mesh to the point of separation from the mesh. The tip of the brush bristle strongly contacts the mesh member of the mesh body, the outer peripheral surface of the tip of the brush bristle rubs against the mesh member, and the dust, dirt, and dust particles attached to the tip of the brush bristle and the mesh member It is forcibly peeled and separated by rubbing away from the brush hair. In particular, if the mesh space opening has a rhombus shape, the brush bristles of the rotating brush change the contact surface between the bristles and the net member while being swung in the feed direction and left and right along the diagonal mesh members. While being sent to the intersection, the adhering brush bristles are rubbed uniformly at the V-shaped intersection, and further rubbed effectively so as to be sandwiched between the V-shaped intersection, Ensures peeling and separation.
In addition, the brush bristles are repeatedly inserted / removed a plurality of times in the plurality of mesh spaces as they rotate, so that the strong peeling force / separation force is repeatedly generated as described above. In addition, as described above, the brush bristles are dragged in a state parallel to the mesh surface while the front end of the brush hits the edge of the projection of the mesh surface and deforms even before and after the brush hair is inserted into the mesh space. As a result, the brush bristles come into contact with the mesh member to scrape and separate the garbage.

Further, since the rotating brush rotates at a predetermined rotational speed, when the rotating brush comes into contact with the mesh member of the mesh body, the brush bristle is impacted by the mesh member, and the elastic brush bristle of the rotating brush receives the impact. Shake away the trash attached to the brush hair. In addition, since the brush bristles contact the mesh member about 20 times during one rotation, the garbage is shaken away by an impact at each contact. Therefore, the garbage is separated and released from the brush hair by this swinging-off.
Garbage deposits that have been rubbed off are discharged outward and downward from the mesh space of the mesh body, and collected by a collecting means such as a receiving tray below or an air suction flow.
Further, even if the deposit adheres to the mesh member, it is struck and peeled off by a large number of brush bristles after rotating, and separated and released from the mesh member.

  If the brush bristle tip part is inserted from the inner mesh surface of the mesh body with a maximum size of 2 to 7 mm, the brush bristle tip part is liable to adhere to garbage, and the tip and tip are 2 to 5 mm from the tip. Effective peeling and separation of the attached part. The insertion dimension of the rotating brush below the main peeling may be long, and the insertion dimension of the upper rotating brush may be shortened.

  In the present invention, if the pitch interval of the mesh members of the mesh body is in the range of 4 to 18 mm, the brush hair has a wire diameter (diameter) of about 0.1 mm, and the insertion depth is 2 to 2 mm. Since the tip of the bristle is about 7 mm, the tip of the brush bristle is securely inserted into the mesh space, and is inserted into and detached from the plural mesh spaces with one rotation of the bristle. And When the pitch interval is 3 mm or less, the brush bristle tip portion may not be inserted. When the pitch interval is 19 mm or more, the number of times the brush bristle tip portion is inserted into the mesh space is reduced, and the peeling / separation force is low. Become.

  As shown in FIG. 30, if the receiving tray is removably attached to the polishing chamber wall below the rotating brush and the mesh body, the separated and separated deposits can be collected in the tray through the mesh space. Moreover, it becomes easy to dispose of garbage in the tray. In addition, the collection power of garbage is weaker than the suction method using negative air pressure.

If the mesh body is detachably attached to the wall of the polishing chamber, the mesh body can be taken out, and the dust adhered to the mesh body can be removed outside the apparatus to facilitate cleaning of the mesh body.
In addition, when the mesh body is mounted and fixed on a mesh body support in which a plurality of plate materials are integrally connected at a predetermined interval vertically and horizontally, the mesh body is repeatedly subjected to a load so that the mesh body is hit with a rotating brush. Can be stably inserted for a long time without causing deformation or displacement of the net. In addition, since the net body and the net body support body can be detached from the polishing chamber wall, it is easy to clean and clean them.

  In the present invention, since the dust attached to the brush hair is rubbed and separated by the net body, the tip of the brush hair is less worn compared to the grindstone method, and the dust can be removed more strongly. -It was assumed that the polishing power could be maintained high. Therefore, the rotating brush can be used continuously without replacement two to three times longer than that of the grindstone plate.

  If both the upper and lower rotating brushes are separated and separated by a mesh body such as a lath mesh, both the upper and lower rotating brushes can exfoliate and separate strong dust deposits.

  If a grindstone plate is placed on the upper end where the upper rotating brushes are lined up, the adhering material at the brush bristle tip can be separated and peeled off by the grindstone plate, and the edge of the brush bristle is made an acute angle to The ability to scrape off dust attached to the corners of unevenness can be recovered, and the cleaning and polishing power of rotating brush medals can be increased. In this case, the mesh body of the present invention and the grindstone plate in the rotating brush can be provided simultaneously by inserting or changing the arrangement position.

  The “rigid planar mesh” of the present invention is hardly deformed or displaced by contact with the brush bristles of the rotating brush, and is not entangled with the brush bristles like a soft mesh, It has sufficient rigidity, hardness, and strength to maintain shape retention without causing deformation or wear even when the brush hair repeatedly contacts. If possible, a material having wear resistance is preferable. As the net body of the present invention, a metal / hard plastic resin such as a lath net or a ceramic material can be used. Further, the outer shape of the net body can be a flat or curved surface.

  In addition, as the net body of the present invention, a large number of net members cross each other diagonally and the mesh shape becomes a rhombus, or the mesh shape intersects at a right angle to make the mesh shape a square or a rectangle, or Punching metal with a high aperture ratio in which circular, oval, rectangular, or star-shaped openings are perforated is also possible. Further, it is possible to have a complicated mesh shape in which the mesh members are radially branched and entangled with each other.

  Alternatively, the number of mesh members in the direction parallel to the rotation axis of the rotating brush of the mesh body is increased, the number of mesh members orthogonal to the number is reduced, and the planar mesh in which the mesh space shape is long in the direction of the rotation axis. It may be the body.

  One side of the shape of the mesh space of the mesh body of the present invention has a length of about 4 to 9 mm, preferably about 5 to 8 mm, and the space shape has a rhombus shape or a V-shaped / X-shaped intersection. Some are preferred. The brush bristles are moved to the narrow V-shaped and X-shaped intersections while moving left and right, and rubbing with the edges of the V-shaped or X-shaped valleys at the intersections. It is preferable because separation and separation can be ensured.

  As the grindstone material of the grindstone layer formed on the surface of the grindstone plate used in the present invention, a grindstone material used for sandpaper, a file, a ceramic polishing cloth, a grindstone or the like can be used. In addition to the adhesion of the grindstone material, it is possible to provide a fine grindstone on the plate material to which the grindstone layer is attached to form a grindstone layer.

  Further, the length of the bristles of the rotating brush is preferably the length of the bristles that causes the bristles to come into contact with the surfaces of the medals as shown in FIG. With this length, the tip of the bristles pierce the rugged corners of the medals, scraping off the deposits, and the elastic force generated by the bending of the bristles creates a force to repel. In order to produce this length, it is necessary to make the length of the upper and lower rotating brushes overlap so that the bristles intersect each other. In addition, by overlapping the rotating brushes, the waste bristles of the upper rotating brush and the lower rotating brush bristles can be separated and separated or moved / dispersed to increase the release of garbage. .

  The pair of opposed rotating brushes is typically a rotating brush arrangement in which the medal transport path faces in the vertical direction in the horizontal direction, but the medal transport path may be vertical and inclined. Rotating brushes facing left and right in the horizontal direction may be used, or the facing direction may be inclined.

  Further, as a means for collecting garbage, a suction type vacuum cleaner (a type in which garbage is accommodated in a filter bag and a type in which dust is captured by a cyclone and collected in a small chamber) can be adopted. The air suction port sucks debris and separated matter such as dust, particles, debris, brush shavings, etc. scattered and floating with the air between the opposing rotating brushes and the surrounding air, and inside the filter bag or cyclone chamber It is better to discharge from the filter bag / compartment if it is stored in a large amount. For this reason, it is preferable to provide openings for air intake and air movement in the casing for storing the rotating brush or the ceiling surface of the polishing chamber and the brush grindstone plate.

  There are various patterns of attachment of the brush grinding stone plate for attachment of the supporting member, the front-rear direction limiting member and the buffering elastic body.

  Hereinafter, the first embodiment shown in FIGS. 1 to 15 and the second embodiment shown in FIGS. 16 to 28 will be described with reference to the drawings. Another embodiment of the present invention is shown in FIGS. Both are examples of a game medal polishing apparatus.
