Subsequently, as shown in FIG. 14, two rows of four pieces of baggage A (different in the longitudinal direction at the time of alignment from the loaded baggage A) that have been pre-aligned on the alignment conveyor 6 are sent to the stowage conveyor 7. Similarly to the above, the loading conveyor 7 is moved forward, downward and laterally to carry the cargo A to a predetermined position, and after positioning it with the side wall of the cargo box C, the cargo A is unloaded. (See Figure 15).

When the above operations are repeated and the cargo A is stacked up to the top layer as shown in FIG. 16, the trolley 2 is moved back a predetermined amount and the cargo is sequentially stacked.

In addition, the loading direction of baggage A is based on the inner dimension (width, width,
(length, height), the attitude control device F selects in advance the direction with the least dead space and the highest loading efficiency.

Further, the present invention is not limited to the structure of the above embodiment, but includes various modifications. That is, the number of items pre-aligned on the sorting conveyor 6 is not limited to 2 rows and 4 items as in the above embodiment, but may be changed as appropriate depending on the size of the luggage A, the width of the packaging box C, etc. And, furthermore, baggage A
The entire width of baggage A may be stacked at one time without having to be stacked separately on the left and right sides.

At that time, the alignment conveyor 6 and the loading conveyor 7
Although it is necessary to increase the width of the cargo box C in accordance with the width of the cargo box C and to change the position of the guide post 14, it is not necessary to move the loading conveyor 7 from side to side.

Furthermore, the cylinders 24 for aligning the loads A provided on the stowage conveyor 7 may be moved at the front edge of the stowage conveyor 7 by the back and forth movement of the guide post 14. On the other hand, the first and second pushers 21, 2
2 may be configured such that the dividing conveyor 4 or the alignment conveyor 6 is provided with the conveying function.

(Effects of the Invention) As described above, according to the cargo conveyance system of the present invention, cargo shipped from a factory etc. can be automatically loaded into the cargo box of a vehicle, thereby reducing the time required for cargo handling work. It is possible to improve processing efficiency by shortening the time. Moreover, since the cargo is transported while controlling its posture using the posture control device,
