[0004]

By the way, when a part of the load to be transferred on the load transfer line is taken out at the end of the line, the remaining load is temporarily stored, or the load is frequently stored. In the case of small packages, if the work of returning the remaining parcels to the original cargo receiving space of the shelf frame by using the parcel transport line is performed again, the waiting time for taking them in and out becomes long. In particular, when the length of the luggage transportation line is long, there is a problem that the wasteful time for the waiting is increased and the work efficiency cannot be improved.

As a means for solving this problem, it is conceivable to provide a branched transfer conveyor line in the middle of the load transfer line and temporarily hold the load on this transfer conveyor line. When there are many types of luggage, in order to take out the prescribed type of luggage that has been sent to the conveyor line, it is necessary to take out another type of post-delivered luggage, which is time-consuming. Since the conveyor line is flat, there is also a problem that the floor area cannot be effectively used.

An object of the present invention is to provide a luggage storage device that solves these problems.

[0007]

In order to achieve the above-mentioned object, the present invention is a luggage storage device arranged in the middle of a luggage transport line, wherein a pair of shelf frames are formed with a plurality of vertically stacked cargo receiving spaces. Between the two, an elevator is arranged so that it can be moved up and down, and the elevator is equipped with means for loading and unloading luggage to and from each of the cargo receiving spaces, while one shelf frame is provided with an unloading section for the luggage transport line and the other. The rack frames are each provided with a carry-in section for the luggage carrying line.
