Long shaku material positioning method and long shaku material positioner

摘要

PURPOSE:To enable automation of hang-down convey of long materials with a crane by positioning a guide member and a positioning member holding the long material between them under standing up condition, shifting the positioning member and positioning the long material along the guide member. CONSTITUTION:For example, 18 pieces in 6 lines of billets 1 are cast at the same time, and fall preventing frame 2 is shifted toward the billet 1 with working of a hydraulic cylinder 22, and the billet 1 is inserted in each grate 3 at the reference position one by one. Successively, a line-up truck 4 is shifted toward the frontmost line of billets 1, and line-up part 18 of the positioning member 5 is abutted on each billet 1, and the billets 1 are held between positioning sloped faces 21 at the fall preventing frame 2 side and positioned to vertex of reverse V shape in the sloped faces 21 and lined up. The line-up frontmost billets 1 are shifted by being hung down with the crane and the second line of billets 1 is shifted to the line-up position and lined up with the same operation by the line-up truck 4. By executing this operation in order, the positioning of billets 1 is easily and accurately executed and working efficiency is improved.
