It is also possible to transport to. (3) Manual (manual) unloading method The producer makes the truck T loaded with the actual pallets P enter the standby section 72 from the outside, and then makes it enter the receiving section 1 from the other entrance 70b, It travels along the third travel route 75 to the manual unloading unit 10a on the front side and is stopped. Then, the producer dismounts from the truck T, and receives the cargo receiving setting device 6
As shown in FIG. 3 (a), after receiving the data by the step 1, the user mounts on the unloading platform 20 of the manual unloading unit 10 a and operates the operation box (not shown) to move the lift device 26. By driving, the height of the unloading platform 20 is adjusted to the height of the loading platform of the truck T, and further, the operation box is operated to project the step 27 and the stopper 28 is attached to the unloading platform 20. To raise.

Then, the producer on the unloading platform 20 manually unloads the real containers E on the real pallets P loaded on the truck T onto the unloading platform 20 (unloading work). At this time, since the gap between the loading platform of the truck T and the unloading platform 20 is narrowed by the protruding step 27, the producer can safely move between the loading platform of the truck T and the unloading platform 20. Also, the real container E unloaded onto the unloading platform 20
Is prevented from protruding toward the conveyor 23 by the raised stopper body 28.

Thereafter, as shown in FIG. 3B, the producer operates the operation box to drive the lift device 26 to adjust the height of the unloading platform 20 to the height of the conveyor 23. , Further, operate the operation box and step 27
And the stopper body 28 is lowered with respect to the unloading platform 20. On the other hand, the empty pallet P in the equipment is transported from the destacker 22 to the front side of the unloading platform 20 by the conveyor 23.

Then, the producer manually transfers the actual container E on the unloading table 20 to the empty pallet P on the conveyor 23. When the transfer of the real container E is completed, the producer places the ID marker 65 on the transferred real container E. As a result, the pallet P left on the truck T becomes an empty pallet, and the pallet P on the conveyor 23 becomes an actual pallet.

Thereafter, the conveyor 23 is driven, and the actual pallet P is placed on the self-propelled carrier 5 via the conveyor 23 and the package shape correcting means 24 and automatically carried. At this time, since the packing shape of the containers E stacked on the actual pallet P conveyed on the conveyor 23 is corrected by the packing shape correcting means 24, the direction of the container E is changed during the unloading work. Even if it shifts, it is corrected to the proper orientation by the package shape correcting means 24.

Thereafter, the producer unloads the container E as described above and loads the truck T loaded with only the empty pallet P from the manual unloading unit 10a along the third traveling route 75 to the container accumulating unit 39. Drive up to. Then, in the container stacking unit 39, the producer manually
The empty container E of the container accumulating section 39 is loaded on the empty pallet P of the truck T and collected (collection work). After that, the producer drives the truck T to travel from the container accumulating unit 39 to the other exit 71b, and exits from the receiving facility A from the other exit 71b.

Further, the truck T is used for the manual unloading section 1
When the truck T runs from 0a to the container stacking unit 39 along the third traveling route 75 and the manual unloading unit 10a is no longer present, the next (successor) truck T moves to the manual unloading unit. 10a is entered, and the work of unloading the next truck T is performed. Therefore, the container stacking unit 39
In the above, when the recovery work is performed on the previous truck T, the work efficiency at the time of receipt is improved by performing the unloading work on the next truck T in the manual unloading unit 10a.

The above is the manual unloading section 10a on the front side.
Although the unloading work is performed in the above, the unloading work can be similarly performed in the manual unloading portions 10b and 10c on the intermediate portion or the back side.

When the truck T stops at the manual unloading section 10a on the front side, the vehicle detecting means 77 detects the presence of the truck T in the manual unloading section 10a. In addition, the truck T uses the manual unloading unit 10a.
By traveling from the container to the container stacking unit 39, the vehicle detection unit 77 detects that the truck T is not present in the manual unloading unit 10a. When this state continues for a fixed time (several seconds), the indicator lamp 78 lights up. The producer in the next (subsequent) truck T, which has been waiting in the waiting section 72, visually confirms that the indicator lamp 78 is lit.
It is possible to promptly and reliably recognize that the front manual unloading section 10a is vacant and immediately move the truck T to the front manual unloading section 10a. This prevents the next truck T from entering the receiving section 1 from the other entrance 70b when the truck T is stopped at the manual unloading section 10a on the front side. Immediately after (the manual unloading section 10a on the front side)
Traffic congestion of the truck T in the vicinity) is avoided.

Further, the manual unloading sections 10a, 10b,
Since the third traveling path 75 of the truck T is formed from 10c toward the container stacking unit 39, the truck T
Can be easily moved from the manual unloading sections 10a, 10b, 10c to the container accumulating section 39.

As described above, since the unloading work can be carried out by the three kinds of methods, it is most suitable among the above three kinds of methods depending on the number of the pallets P and the containers E loaded on the truck T and the loading state. It is very convenient because you can select various unloading work.
