The transport system shown in FIG. 5 has a container for picking fruits and vegetables brought in from each farmhouse on the front side in the transport direction (conveyor side of the container) of the transport conveyor A laid from the container collection site in the sorting field to the sorting site. The containers B are stacked and transported in four stages, and the containers B stacked in four stages are separated by the stage disassembling device C during the transportation and are transported one stage at a time to the destination sorting field.

The transport system shown in FIG. 6 has a conveyor A located on the front side in the transport direction (container collection side) of a transport conveyor A laid from the container collection field in the sorting field to the sorting field.
Containers B with fruits and vegetables brought in from each farm by laying a number of roller conveyors E at arbitrary intervals in the longitudinal direction of
Is placed on the end G of the desired roller conveyor E in four steps, and the container B to be brought in next is pushed out by hand to the side of the conveyor A for conveyance to place an empty space there. , Or another vacant roller conveyor E
I will put it on. When the roller conveyor E is filled with the container B, the innermost container B is
Are extruded onto the conveyor A for transportation, transferred sequentially from the container B on the conveyor A side to the conveyor A for transportation, and can be transported to the sorting field by the conveyor A. Also in this case, the containers B stacked in four stages are disassembled into one stage by the stage disassembling device C provided in the middle of the conveyer A.

[0005]

In the container transport system shown in FIG. 5, since many containers B cannot be loaded on the transport conveyor A at one time, the containers B that cannot be loaded on the conveyor A can be temporarily placed in the sorting field. When the transfer conveyor A is temporarily placed in an empty space outside and the transfer conveyor A is vacant, the container B that has been temporarily placed must be placed on the transfer conveyor A. As a result, the container B has to be carried twice, and the labor burden on those who work in the sorting field has been heavy. There is also a problem that the container B must be secured because the container B cannot be stored without a large vacant space.

In the container transport system shown in FIG. 6, it is necessary to secure a place for laying a large number of roller conveyors E in the sorting field. Even if the space can be secured, the place where the roller conveyor E is laid cannot be used for other purposes, so that it is difficult to realize unless it is a sorting field having a very large site.

An object of the present invention is to provide a method of transporting a fruit vegetable container and a pallet used therefor, capable of handling a large number of containers even in a small space and moving the containers entirely by a machine. is there.
