Depending on the type of fruits and vegetables, some of them may be packed in a bag and packed in a box before shipping. In this case, after sorting, they are transported one by one and packed in a bag as before. As a result, the second product may be rubbed and damaged when it is inserted, which is a cause of lowering the commercial value. In addition, in the case of fruits and vegetables, since they are not straight cylindrical and are deformed, there is a problem that even if the bags contain a prescribed number of fruits and vegetables, the last one will not fit in each bag. Therefore, it is desirable to convey the piles in the piled state so that the piles can be loaded into the bag in the piled state. However, in order to convey the piles in the piled state, the conveying section must be U-shaped. Instead, it is necessary to dispose two conveyor belts so as to face each other in a V shape, or to use a roller conveyor having an H-shaped cross section. These conveyors are expensive, and the number and size of piles of conveyors are large. It was difficult to make a shape that fits with.

[0004]
