PURPOSE:To prevent a bogie truck and a shutter from being damaged, by making a conveying system instructible for warehousing work only in time of each block shutter inside a storehouse being opened, while constituting the system so as to cause these shutters to be closed only in time of a stand-by state after operations are over, in case of the conveying system using an unmanned battery car. CONSTITUTION:A shutter state monitor device 44 inputs the shutter state of each shutter (i) inside a storehouse into a block route determination device 47 as shutter opening limit information 42. Simultaneously with this operation, a signal 15 out of a warehousing-delivery setting table 14 is inputted into a stock control device 20 as well as warehousing and delivery demand signals 25-27 and a signal 17 out of the warehousing-delivery setting table 14 are all inputted in the same manner, and in accordance with these data, the block route determination device 47 outputs an instruction of these warehousing and delivery operations to only the block that opens its shutter and likewise outputs a control signal so as to keep the shutter opened till operation is over and it goes back to a stand-by state. Thus, a collision between a bogie truck and the shutter is prevented so that any damage due to the collision is obviated.
