If it is in 0), proceed to the next step 3.

That is, when the interlock is in the locked state, there is a high possibility that the worker is working in the passage that is currently being formed. Is invalidated, and no new passage is formed. If the interlock is in the unlocked state (K = 0), the operation of the passage formation push button 63 is effective, and the process proceeds to step 3.

In step 3, path information for forming a path obtained from the operation signal is transmitted from the movable shelf control device 61 to the movable floor control device 60, and the process proceeds to the next step 4. In Step 4, the motor 50 is driven to move the movable floor 30 in the target passage direction, and in Step 5 until the movable floor position detection sensor 65 corresponding to the target passage detects the movable floor 30 in the next Step 5. The movement of the return movable floor 30 is continued.

When the movable floor 30 reaches the target passage position, a predetermined movable floor position detection sensor 65 detects the movable floor, and
Proceeding to step 6, the movement of the movable floor 30 is stopped, and proceeding to the next step 7, this time the predetermined unit moving shelf 4 is run to form a target passage. The process returns from step 8 to step 7 until the formation of the target passage is completed, and the traveling is continued. When the formation of the target passage is completed, the process proceeds to step 9 and the interlock is automatically locked (K = 1), and step 1 is performed.
