PURPOSE:To provide a titled device which places materials to be stored in home positions with a storage device having three stages of home positions in a machine frame having two stages of lifting frames by supporting a receiving base by means of hooks, which are movable in and out, of the lifting devices and supporting the receiving base by the hooks, which are movable in and out, of the machine frame as well. CONSTITUTION:A receiving base 7 having a material 4 to be stored is supported by lifting hooks 17, which are movable in and out, of two stages of upper and lower lifting frames 8 which are moved upward and downward by means of the motor 22 of a machine frame 6 and chain mechanisms 25, 26. When the frames 8 come to the home position in the middle stage, the 1st hooks 18 for fixing provided to a horizontal machine frame 6b come out and the frames 8 descend to support the receiving base in the home position. When the frames 8 come to the home position in the upper stage, the 2nd hooks (with guide rollers) for fixing of the horizontal machine frame come out similarly to support the base 7. When the frames 8 come to the home position in the lower stage, the base 7 is supported by guide rollers 21. The hooks 17 are retracted and the frames 8 are moved upward to receive and support the base with lower hooks 17 in the stage of transferring the receiving base in the upper stage of the frames 8 to the lower stage. |
