On the other hand, when the storage case is carried out to the external conveyor 20, the elevating conveyor 11 descends. As the elevator conveyor 11 descends, the shaft 111 fixed to the elevator conveyor 11 descends and pushes down the pair of side edge projections 122 of the gate bridge 12, thereby opening the opening 7
The gate bridge 12, which is in a bridge state with the lower end surface of the, rotates around the fixed shaft 102 and separates from the opening 7 and stands up.

Next, at the time of returning the article, when the return button (not shown) provided in the private room 19 is pressed, the external conveyor 20 operates in the reverse direction,
The storage case is transported to the opening 7. At the same time when the return button is pressed or when the storage case is transported immediately before the opening 7, the elevating conveyor 11 moves up. When the elevator conveyor 11 is raised, the gate bridge 12 is raised again by the shaft 111 attached to the elevator conveyor 11 to the bridging state again to the vault opening 7, and the storage case is sent to the cross conveyor 10 through the gate bridge 12. . In this state, the article detection sensor 14 detects the storage case, the elevator conveyor 11 and the stopper 8 are lowered, and the storage case on the cross conveyor 10 is the conveyor roller 101 of the cross conveyor 10.
Is rotated and is transferred onto the internal conveyor 4 and returned to a predetermined position on the storage rack 3 in the safe 2.

Here, as in the case of taking out the storage case from the storage shelf 3 and carrying it out to the private room, when the elevating conveyor 11 descends, the gate bridge rotates around the fixed shaft 102 and separates from the rotating unit 7 to be in a standing state.

In the description of the structure and operation of this embodiment, the customer's storage case is selectively pulled out and stored from the storage cases stored in a large number of storage areas located in the storage shelf 3 arranged in the vault 2. Since the device for taking in and out from the shelf 3 to the internal conveyor 4 is a known fact, detailed description thereof will be omitted.

Further, in the present embodiment, the lifting conveyor is provided near the opening inside the safe room, and the gate bridge is attached to it. However, the lifting conveyor is provided near the opening of the external conveyor, and the gate bridge is described above. It goes without saying that the mounting internal conveyor may be extended to the opening portion in the same manner as in the embodiment.

[Effect of device]

As described above, according to the present invention, the gate bridge is rotated from the rising state to the bridging state and from the bridging state to the rising state so as to connect the elevator conveyor and the external conveyor to each other. Since it is linked to the lifting conveyor without providing a dedicated motor for the above, the structure can be simple and inexpensive.

In addition, since the elevator conveyor is usually lowered and the gate bridge is not bridged to the opening, there is no problem in closing the gate door in the event of an unexpected fire or accident.
