（２）開口部５の広い砥石カバー３では侵入空気量が大
となり集塵装置容量が大きくなる。(2) With the grindstone cover 3 having a wide opening 5, the amount of air entering is large and the capacity of the dust collector becomes large.
（３）金属帯ｌの端面の乾式での重研削時は切削粉も大
きく慣性が大きくなり砥石カバー３より飛び出す粉塵の
集塵捕集が困難である。(3) During heavy dry grinding of the end face of the metal strip 1, the amount of cutting powder is large and the inertia is large, making it difficult to collect the dust that flies out from the grinding wheel cover 3.
（４）砥石カバー３を使って粉塵を集塵するとき、集塵

以下、本発明を図面を参照してその実施例に基づいて説
明する。DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below based on embodiments with reference to the drawings.
本実施例は第１図、第２図、第３図に示され、研削砥石
２は回転することにより被研削材である金属帯ｌを研削
するものである。This embodiment is shown in FIGS. 1, 2, and 3, in which a grinding wheel 2 rotates to grind a metal strip l, which is a material to be ground.
吸引フード４は図示されない吸引手段に接続され、研削
砥石２を被覆する。The suction hood 4 is connected to suction means (not shown) and covers the grinding wheel 2.
砥石カバー３は吸引フード４内で該研削砥石２の周縁に
沿って所定間隔をおいて配設される。The grindstone covers 3 are disposed within the suction hood 4 along the periphery of the grindstone 2 at predetermined intervals.
吸込口４ａは研削点から該研削砥石２の周縁を１周した
位置の最終端部において該砥石カバー３の端部と該吸引
フード４の端部により形成される。The suction port 4a is formed by the end of the grindstone cover 3 and the end of the suction hood 4 at the final end of a position that has gone around the circumference of the grinding wheel 2 once from the grinding point.
開口部５は金属帯１が研削砥石２と当接するために吸引
フード４に形成される。An opening 5 is formed in the suction hood 4 for the metal strip 1 to come into contact with the grinding wheel 2 .
シール材６は着脱自在に装着され開口部５をシールする
。The sealing material 6 is detachably attached and seals the opening 5.
被研削材である金属帯ｌは第１図の側面図に示すように
端面に垂直に当接された研削砥石２の反時計方向の回転
によって研削される。As shown in the side view of FIG. 1, the metal strip l, which is the material to be ground, is ground by counterclockwise rotation of the grinding wheel 2 which is perpendicularly brought into contact with the end surface.
このとき金属帯ｌは連続的に第２図の平面図の矢印１１
方向にＯ〜Ｓｏｎ／ｗｉｎで送られる。At this time, the metal band l is continuously connected to the arrow 11 in the plan view of FIG.
It is sent in the direction O~Son/win.
ここで、速度変化による切込量の制御は研削砥石２の押
圧力により行われ、０．１〜１．０ｍｍの範囲で一定値
の研削ができる。Here, the depth of cut is controlled by the speed change by the pressing force of the grinding wheel 2, and grinding can be performed at a constant value in the range of 0.1 to 1.0 mm.
金属帯ｌの端部の乾式重研削時の研削砥石２の砥粒、結
合剤および研削粉等の粉塵は金属帯ｌと研削砥石２の接
触した直後に発生し、発生量のほとんどが研削点の接線
方向すなわち第１図において矢印ｌＯ力方向ほぼ垂直に
落下する。Dust such as abrasive grains, binder, and grinding dust of the grinding wheel 2 during dry heavy grinding of the end of the metal strip 1 is generated immediately after the metal strip 1 and the grinding wheel 2 come into contact, and most of the generated amount is at the grinding point. It falls in the tangential direction, that is, almost perpendicular to the direction of the force indicated by the arrow IO in FIG.
このため、粉塵は金属帯１の上面に乗ることはないが、
その後、研削砥石２から遠心力により脱落した粉塵は研
削砥石２の外側の砥石カバー３の内面に沿って移動する
。For this reason, dust does not get on the top surface of the metal strip 1, but
Thereafter, the dust that falls off from the grinding wheel 2 due to centrifugal force moves along the inner surface of the grinding wheel cover 3 outside the grinding wheel 2.
このため、粉塵は終端において、金属帯ｌの端面上部に
衝突後反発する。Therefore, at the end, the dust collides with the upper end surface of the metal strip l and then repels.
そこで、この反発した粉塵を集塵するように吹込口４ａ
を配置する。Therefore, the air inlet 4a was designed to collect this repulsed dust.
Place.
連続的に使用される研削砥石２は摩耗により。The grinding wheel 2 that is used continuously is due to wear.
その直径は最小径となったとき、金属帯ｌは第２図の位
置１ａまで移動する。When its diameter reaches its minimum diameter, the metal band l moves to position 1a in FIG.
このため、開口部５は研削砥石２の摩耗方向と金属帯ｌ
の研削時の上下変動も含め上下方向にも必要になるため
、周囲に取付けられたシール材６によりシールされる。For this reason, the opening 5 is located between the wear direction of the grinding wheel 2 and the metal band l.
Since it is also necessary in the vertical direction, including the vertical fluctuation during grinding, it is sealed by the sealing material 6 attached to the periphery.
６
このシール材６は摩耗や変形によって開口部５のシール
不良が発生しても容易に交換できるように着脱自在の構
造とする。6. This sealing material 6 has a removable structure so that it can be easily replaced even if sealing failure of the opening 5 occurs due to wear or deformation.
このため、余剰空気の侵入を抑制し、研削時に金属帯１
の上面に堆積した粉塵の掻き起し作用による集塵効率も
向上する。For this reason, it suppresses the intrusion of excess air, and the metal strip 1 during grinding.
The dust collection efficiency is also improved by the action of scraping up the dust accumulated on the top surface.
また、衝突時゛の反発を利用した吸引口４ａでは反発速
度に見合う速度で吸引している。In addition, the suction port 4a, which utilizes the repulsion at the time of collision, sucks at a speed commensurate with the repulsion speed.
第２図に示すように研削砥石２の摩耗時において金属帯
１が位置１ａに位置しても集塵効果を維持させるために
吸引フード４は研削砥石２の側面に延長し、吸引口４ａ
を延長し集塵する構造とする。As shown in FIG. 2, in order to maintain the dust collection effect even when the metal band 1 is located at position 1a when the grinding wheel 2 is worn out, the suction hood 4 extends to the side of the grinding wheel 2, and the suction port 4a
The structure is extended to collect dust.
さらに、本実施例においては第３図に示すように吸引フ
ード４の元管近傍の砥石カバー３の端部には風量調整ダ
ンパ７を設け、金属帯ｌの上方向と下方向の吸引風量調
整も行う。Furthermore, in this embodiment, as shown in FIG. 3, an air volume adjustment damper 7 is provided at the end of the grindstone cover 3 near the main pipe of the suction hood 4 to adjust the suction air volume in the upward and downward directions of the metal strip l. We also do
本発明は以上説明したように、

（２）重研削条件で（研削代：０゜ｌ−１，０ｍｍ、研
削速度：０〜６０ｍ／ｍ１ｎ）研削することができる。(2) Grinding can be performed under heavy grinding conditions (grinding allowance: 0°l-1.0mm, grinding speed: 0-60m/m1n).
（３）金属帯上面に粉塵が乗らないので次の工程で金属
帯表面に疵を発生させることがない。(3) Since dust does not get on the top surface of the metal strip, no scratches will be generated on the surface of the metal strip in the next process.
（４）研削する時の粉塵をほぼ完全に除去することによ
り従来必要としていた粉塵除去の洗浄装置の省略が可能
