PURPOSE: To store various cores in a main die using a robot, and to prevent the core from being brought into contact with the inner surface of the main die to break the main die.
CONSTITUTION: A robot having an arm movable in the horizontal and vertical direction, a hand part fitted to the tip part of the arm to hold a core, and a driving means to move the arm to the position where the core held by the hand part is stored in a main die is provided. A non-contact type distance measuring instrument which is lowered to the prescribed position in the main die, and measures the distance between the distance measuring instrument and the circumferential surface of the main die is fitted to the hand part, and the distance between the hand part and the main die is operated by a first operating means based on the measurement by the distance measuring instrument. The correction in storing the core of the arm necessary to store the core in the main die without bringing the core held by the hand part into contact with the circumferential surface of the main die is operated by a second operating means based on the results of operation by the first operating means, and the arm is moved based on the results of operation of the second operating means to accommodate the core.
