As described above, according to the first aspect of the present invention, when the load is stored from the cargo handling section to the storage section of the shelf, the spread of the widening section is restricted by the packing state regulating means. In addition, the widening portion can be prevented from being caught on a part of the shelf or a part of the taking-in / out means. Therefore, it is possible to handle the load with the spread portion opened.

Further, according to the fourth aspect of the invention, when the load is stored from the loading section to the storage section of the shelf, the load is transferred from the upstream side to the downstream side on the transfer path by the transfer means. At this time, since the other regulating device moves to the retreat position and retreats from the transport route, the other regulating device does not interfere with the load on the transport route, and the load can be transported without any trouble.

Then, one side of the load abuts against one of the regulating devices, and then the other regulating device moves from the retreat position to the entry position and enters the transport path.
Since one restricting device and the other restricting device at the entry position sandwich both sides of the load, the lateral spread of the unfolded portion of the load is restricted.

Further, according to the fifth aspect of the invention, when the load is stored from the cargo handling section to the storage section of the shelf, the load is transferred from the upstream side to the downstream side on the transfer path by the transfer means. At this time, since the support member is rotated to the retreat position by the driving device of the other regulating device and the regulating roller is retracted from the transport path, the regulating roller does not interfere with the load on the transport path. And the load can be transported without any trouble.

Then, one side of the load abuts against one of the regulating devices, and then the driving member of the other regulating device causes the support member to rotate from the retracted position to the rush position, and the regulating roller moves on the transport path. By entering, the regulating roller of one regulating device and the regulating roller of the other regulating device sandwich both sides of the load, so that the spread of the widening portion of the load is restricted.

In this state, the loading / unloading device receives the load from the transport means side and stores it in the storage section of the shelf. In addition, when the loading / unloading device receives the load from the transporting means side, the regulating roller of the other regulating device rotates in contact with the load in accordance with the movement of the load. Can be taken to the side.

According to the sixth aspect of the present invention, when the loading / unloading means receives the load carried to the cargo handling unit and stores it in the storage unit of the shelf, the loading / unloading means load regulation means moves the load to the side of the widening section. Since the spread of the opening is restricted, the widening portion can be prevented from being caught on a part of the access means.

According to the seventh aspect of the present invention, when the loading / unloading means receives the load carried to the cargo handling section and stores it in the storage section of the shelf, the loading mode for the shelf controls the side of the widening section. Since the spread is restricted, the widening portion can be prevented from being caught on a part of the shelf.
