(産業上の利用分野)
本発明は研削装置に係り、より詳細には、複数列の被加
工材を連続的に、かつ、同時に研削加工し得る高能率の
研削装置に関する。Detailed Description of the Invention (Field of Industrial Application) The present invention relates to a grinding device, and more particularly, to a highly efficient grinding device that can grind multiple rows of workpieces continuously and simultaneously. Regarding.
(従来の技術及び問題点)
被加工材1例えば、粉末冶金法により製造される磁石、
殊にフェライト磁石は、酸化鉄を主原料とする原料を粉
砕し、プレスにより磁場下で成形された後にトンネル炉
で焼結し、研磨等の加工に供されて製造されている。(Prior art and problems) Workpiece 1 For example, a magnet manufactured by powder metallurgy,
In particular, ferrite magnets are manufactured by pulverizing a raw material whose main raw material is iron oxide, molding it by pressing under a magnetic field, sintering it in a tunnel furnace, and subjecting it to processing such as polishing.
一般にこの種の磁石は、小型であり、平坦状のものはも
とより、弓形、半月状などの載置不安定な形状を有する
ものが多く、更に衝撃により損傷し易いため、その取扱
いには細心の注意が払われている。In general, this type of magnet is small, and many have shapes that are unstable when placed, such as a flat shape, an arcuate shape, or a half-moon shape. Furthermore, they are easily damaged by impact, so they must be handled with great care. Attention is being paid.
特に磁石の表裏面を回転砥石によって研磨するには、損

た。また、研磨工程の前後の工程(砥石の場合、プレス
成形、焼結工程と洗浄、乾燥工程)を高速自動化を図っ
てもこの研磨工程が隘路となって生産性の向上を阻害す
る原因となる。In particular, when polishing the front and back surfaces of a magnet with a rotary grindstone, it is necessary to feed the magnets one after the other in succession, taking into consideration their tendency to damage. In this regard, conventional methods have relied on manual work such as aligning the magnets in a desired direction and pushing them in, which is inefficient and dangerous. Furthermore, even if the processes before and after the polishing process (in the case of grindstones, press forming, sintering, cleaning, and drying processes) are automated at high speed, this polishing process becomes a bottleneck and hinders productivity improvement. .
なお、このような事情は、例示した磁石の場合のみに限
らず、他の被加工材の研削加工においても往々にしてみ
られるものである。Incidentally, such a situation is not limited to the case of the illustrated magnet, but is often observed in the grinding process of other workpieces.
