Abstract

PURPOSE:To enable accurately grinding the defective part in such a way that when conveying the round steel piace, the position of the defective part on the outer periphery of the steel piece is stored as the distance from the tip and the angle from the horizontal plane, and the first position of the defective part is verified just before the processing equipment. CONSTITUTION:At the same time as the position of the defective part of a round steel piece 1 is detected by means of a detector 3 which is arranged on a roller conveyor 2 so as to be able to cover the outer periphery of the round steel piece 1 to be conveyed, they are stored as the positional data of the distance from the piece, and of the angle from the horizontal plane, etc. Next to it, the round steel piece 1 is transferred to a carrier 8 equipped with cradle rolls 9 to turn the round steel piece 1, and the carrier 8 moves ahead until the first defective part is positioned to a detector 11. Then, the rolls 9 are turned, and the round steel piece 1 is turned until the defective part comes to the upper part. In this condition, the carrier 8 is moved forward, and the defective part is ground and removed by means of a grinding stone 10. Thus, after each defective part of the round steel piece 1 is ground seriatim, the carrier 8 is returned to its original position, the round steel piece 1 completely ground on the rolls 9 is transferred onto the conveyor 2 by means of a transfer loader 7, and it is transferred to another process.
