Abstract

PROBLEM TO BE SOLVED: To prevent quality information from being distorted and to automate sampling and to save manpower by providing a means for aligning and carrying, transporting, and cutting curved wires one by one as they remain curved and a means for dividing and collecting a gathered sample. SOLUTION: For example, curved wires S that are cut and gathered at approximately 300-600mm from a rolled coil wire are retained one by one with both edges turned upward by a support tool 9 that is provided in the direction of a conveyor width of an endless conveyor 6 and are carried on a horizontal surface in units of lot. The wires S are lifted by a lifter 14, are grasped by a horizontal chuck 15 at the transport termination part and are transferred to a closed-end retaining tool 38 of a cutting means 3. The wires S that are received by a stopper 40 so that a position can be adjusted freely are cut to a sample length that is suited for each kind of test. Samples are sent to a collecting means 4 by a chuter and are divided and collected by a tray T with a cell in vertical and horizontal lattice shape, and a remaining material is thrown to a collecting tool 53 by releasing the bottom of the retaining tool 38.
