In the embodiment, the scallops and the like put into the bucket 35 are sorted into eight groups by the weight, and which group the scallops belong to is input to the controller after the weighting. Then, the weighed scallop scallops and the like are sorted by weight by the carrying device 20 and housed in groups in the lower container. The sorting operation will be described below.

The group by weight corresponds to any electromagnetic solenoid. After accommodating the scallops or the like in the bucket, the travel distance of the two-row chain 33 until reaching the corresponding electromagnetic solenoid is calculated by a pulse encoder or the like, and after a predetermined time, the corresponding electromagnetic solenoid 64 is excited for a predetermined time. It has become. When the electromagnetic solenoid 64 is excited, the actuator 65 and the engaging member 66 in FIG. 10 are brought into the state shown in the figure, and the rod portion 71 is moved forward in the traveling direction of the rear wall portion 35d of the desired bucket 35 which is going to pass immediately below. Will be placed. Therefore, since the bucket 35 travels with the rear wall portion 35d in contact with the rod portion 71 of the engagement member 66, the bucket 35 rotates counterclockwise about the shaft 51 in FIG. The stored scallop scallops are guided by the ribs r, fall to an appropriate position on the lower collecting chute 76, and are stored in a container or the like.

Thereafter, similarly, in the subsequent bucket, a predetermined electromagnetic solenoid is excited, and the scallops pass through the chute and are accommodated in containers by weight. Therefore, the scallop scallops are sorted by weight within a predetermined range and housed in a container or the like.

When the bucket 35 finishes carrying the stored items, the front wall portion 35c and the rear wall portion 35d return to the upward inclination due to their own weights, and the vertical transfer path portion downward from the remaining horizontal transfer path portion, and After traveling along the lower horizontal transfer path, the posture is again held by the guide piece 37, and the vertical transfer path between the gear device 26 and the gear device 23 is transferred.
