【考案の詳細な説明】 本考案は穀物、飼料、窯業、その他の粉砕工程において
、粉粒（小塊）を選別する篩の網張り金具に関するもの
である。[Detailed Description of the Invention] The present invention relates to a mesh fitting for a sieve for separating powder grains (small lumps) in grain, feed, ceramics, and other grinding processes.

従来、上記篩に網張りする場合、第１〜２図に示すよう
に、網張り機３の所定位置に篩枠１を定置し、ついでそ
の上面に網２を拡げ、つぎに第３〜４図に示すように、
基板４に固定した多数の針７ａを網２の網目につきとお
す。Conventionally, when meshing the above-mentioned sieve, as shown in FIGS. As shown in the figure,
A large number of needles 7a fixed to the substrate 4 are passed through the mesh of the net 2.

ついで可撓性板（例えばゴム板）６を張りつけた押え板

板５を締付ける。Next, the flexible plate (for example, a rubber plate) 6 is aligned with the needle hole 7b of the presser plate 5 to which it is attached, and then the presser plate 5 is tightened with the fastener 12.

これによって、網２を基板４に固定させる。その後、第

め、網２を緊張状態にいたらしめる。This fixes the net 2 to the substrate 4. Thereafter, as shown in FIG. 2, by rotating the threaded rod 9 with a handle screwed onto the bushing 11 fixed to the base plate 4, the bushing 11 moves in the direction of the arrow (solid line in FIG. 2). 2 to be in a nervous state.

この状態で、網２は篩枠１に接着剤（図示せず）で塗着
するか、釘（図示せず）を打ちつけて篩枠１に固定され
る。In this state, the screen 2 is fixed to the sieve frame 1 by applying an adhesive (not shown) to the sieve frame 1 or by nailing it with nails (not shown).

つぎに、ハンドル付きねじ棒９を逆回転すると、基板４

切断して、網２を張りつけた篩枠１を取出す。Next, when the threaded rod 9 with handle is rotated in the opposite direction, the board 4
As the screen moves in the direction of the arrow (dotted line in Figure 2), the end of the screen 2 becomes loose, and is cut with a small force or with a suitable hand tool such as scissors to remove the sieve frame 1 with the screen 2 attached.

この網張り金具では、あらかじめ基板４に固定した多数
の針７ａに対応する多数の針穴７ｂを可撓性板６および
押え板５に穴明し、該針７ａを針穴７ｂにはめ込む必要
があるため、針７ａと針穴７ｂの位置合せに要する時間
が多大であり、また先鋭な針先で指または手を負傷する
例が多数上ずるという欠点がある。In this mesh fitting, it is necessary to drill a large number of needle holes 7b in the flexible plate 6 and the presser plate 5 corresponding to the large number of needles 7a fixed to the substrate 4 in advance, and to fit the needles 7a into the needle holes 7b. Therefore, there are disadvantages in that it takes a lot of time to align the needle 7a and the needle hole 7b, and there are many cases where fingers or hands are injured by the sharp needle tip.

これに対し、本考案は第５〜６図に示すごとく、表面に
三角錐状の突起部７Ｃを例えば単列、複列、もしくは千
鳥状に形成しこの突起部７Ｃに網２の網目をひっかけた
のち、可撓性板６を張りつけた押え板５をファスナー１
２により締付ける。In contrast, in the present invention, as shown in FIGS. 5 and 6, triangular pyramid-shaped protrusions 7C are formed on the surface in a single row, double row, or staggered pattern, and the mesh of the net 2 is hooked onto these protrusions 7C. Afterwards, attach the presser plate 5 with the flexible plate 6 attached to the fastener 1.
Tighten by 2.

この場合、押え板５および可撓性板６には針穴をあける
必要がなく、従来の金具による場合にくらべて網２の固
定所要時間が短縮できる。In this case, there is no need to make needle holes in the presser plate 5 and the flexible plate 6, and the time required for fixing the net 2 can be shortened compared to the case of using conventional metal fittings.

上記突起部７Ｃの形状は、ヤスリの鬼目とほぼ類似であ
って、目立て方向は網２の引張り方向（第６図の矢印方
向）と一致させることが好ましい。The shape of the protrusion 7C is almost similar to that of a file, and it is preferable that the sharpening direction coincides with the pulling direction of the net 2 (the direction of the arrow in FIG. 6).

また目立て間隔および高さは網の形状、網線の太さ、網
目寸法により適宜選ぶが、概ね１〜３ｍｍ程度である。Further, the dressing interval and height are appropriately selected depending on the shape of the mesh, the thickness of the mesh lines, and the mesh size, but are generally about 1 to 3 mm.

ついで、前記同様の要領で篩枠１に網２を固定したのち
、網２を張りつけた篩枠１を取出す。Then, after fixing the screen 2 to the sieve frame 1 in the same manner as described above, the sieve frame 1 with the screen 2 attached is taken out.

このように、本考案の網張り金具を使用する場合、従来
の網張り金具にみられた針による負傷が無くなるととも
に、針と針穴との位置合せが不要となって、網張り作業
の安全化と網張り工数が短縮でき、その技術的成果は著
大である。In this way, when using the netting fittings of the present invention, injuries caused by the needles that occur with conventional netting fittings are eliminated, and there is no need to align the needles with the needle holes, which improves the safety of netting work. The technical results are significant, as the number of man-hours required for lining and netting can be shortened.
