That is, the containers carried from the farmers are transferred by the cargo receiving conveyors 5 and 5 and the take-out conveyors 7 and 7 of the cargo receiving section 1. The grade evaluator puts out one fruit from the container and evaluates the grade according to its appearance, etc., and places it on the selection cup parts 9, 9 ... Corresponding to a predetermined grade.
The weight of the fruit on the conveyor 6 is detected by the weight measuring device 11 for each cup, and the detection signal is input to the control unit 12. The control unit 12 determines which class the fruit belongs to, and when the fruit reaches the classifying and extracting units 4 and 4 of a predetermined grade and class, the rails outside the drawing are operated to eject the fruit by overturning.

The fruits stay on the fruit stock table 13 and are packed by a packing worker. At this time, it is known in advance which size of the empty cardboard box is to be selected, and the worker is in charge of the multi-stage box conveyors 44a, 44b or 4
The predetermined box size is selected from the various types of boxes supplied at 4c, taken out, placed on the elevating frame 16, and stands by.

The elevating frame 16 is raised to stand by and the boxing operation is continued. When the first step of the boxing is completed, the partitioning material 20 is added to enable the second step supply. When the packaging of one box is completed in this way, the elevating frame 16 is lowered and the relay roller conveyor 1
It is transferred to the eight surfaces and transferred, and then transferred to the product conveyor 19. When the cardboard box becomes full on the way, the corresponding box is taken out from the distribution conveyors 44a, 44b or 44c.

When the number of corrugated cardboard boxes waiting on the distribution conveyor 44 is reduced, the operator is notified of the fact or the inventory status of the corrugated cardboard boxes is detected, so that the required size of the corrugated box is increased. In order to supply the corrugated cardboard with the materials, the corrugated cardboard supply device 22 is loaded with the corrugated cardboard.
