That is, the cargo pallet pallet transposing fork 61 moves forward with respect to the shuttle gauge 24 of the loop track 21, takes out and holds the pallet 23 by the pair of forks 86, and retreats to the original position and then horizontally rotates 90 degrees. It faces the fixed conveyor 64. Then, the luggage pallet transshipment fork 61 moves forward again to pass the pallet 23 held on the fixed conveyor 64.

Then, the fixed conveyer 64 sequentially transfers the pallets 23 received from the fork 61 for loading and unloading the cargo pallets to the inclined conveyer 65 in the horizontal state. The sloping conveyor 65 conveys the pallet 23 to the loading and unloading station 17 intermittently or continuously at a low speed as appropriate. During this time, the operator uses the work conveyor 66 to adjust the load and change the load of the pallet 23. To replenish and remove.

When the pallet 23 transferred by the inclined conveyor 65 reaches its end, the pallet 23 to be unloaded by the forklift 57 at the loading / unloading station 17 is loaded onto the transport truck 58, and the pallet 23 is returned to the warehouse 11. It is moved to the inclined conveyor 65 of the side conveyor transport path 63. In addition, the pallet 23 carried by the carrying truck 58 is also included in the inclined conveyor 6 of the conveyor carrying path 63 on the receiving side.
Transfer to 5. The sloping conveyor 65 in the conveyor conveying path 63 on the warehousing side receives the received pallet 23 in the loop track 2
It is transferred to the first side and then to the fixed conveyor 64. Here, the luggage pallet transshipment fork 61 transfers the pallet 23 on the fixed conveyor 64 into the shuttle gauge 24 waiting at the connection portion between the conveyor transport path 63 on the storage side and the loop track 21. Then, the shuttle gauge 24 on which the pallet 23 is mounted is moved to a predetermined position by the traveling carriage 22 along the loop track 21, and the pallet 23 is stored in the rack 12 of the warehouse building 11 by the transfer conveyor 16.

As described above, according to the present embodiment, at the time of loading and unloading of the luggage pallet 23, the pallet 23 is transferred from the shuttle gauge 24 to the unloading side by the luggage pallet transfork 61 at a predetermined exit position on the loop track 21. While being delivered to the conveyor transport path 62 and transferred to the cargo handling area 17,
The pallet 23 carried in by the truck 58 is transferred to the conveyor transport path 63 on the warehousing side, and is delivered to the shuttle gauge 24 by the cargo pallet transshipment fork 61 to be stored. Therefore, it is possible to unify the flow of the pallets 23 to be put in and out, and to circulate the pallets 23 quickly without any stagnation.
