A conventional fish and shellfish weighing device, for example, a fish and shellfish sorting device such as kiwi, octopus, abalone, etc. measures the weight of the fish and shellfish and selects them for each specific weight range. For example, if classified by 20g, fish weighing 95g is selected in the range of 80~100g, and fish weighing 105g is selected in the range of 100~120g. When the selected fish and shellfish are fully loaded in the box, the box is moved and the loaded fish are weighed on a scale with a certain weight, for example, 20Kg, and the fish are neatly arranged and packaged in a box. That is, for example, if one fish is around 100g, 200 fish are arranged in one box and boxed. For this work, a separate manpower is input and the box work is performed. As a result, the labor cost rises, and the sorting time is lengthened due to the separate box work (post-processing of the sorting process), which has also been a factor in reducing the freshness of the fish.

In addition, in the conventional fish sorting device such as early bird or octopus, the fish transported by the conveyor is dropped and discharged from the conveyor by the torque of the discharge scraper, and it was not easy to accurately control the operation timing of the discharge scraper. . This has resulted in early damage and some ejection errors.

In addition, in general, two checkweighers were installed to increase the throughput in order to increase the throughput. However, when the amount of fish and shellfish to be sorted is not large and different entities want to separate each separately, it is necessary to separate such a checkweigher and use it as two checkweighers.

In addition, when the sorted items are transported and placed on the transfer conveyor, the split rotary scraper does not operate properly if the sorted items are caught in the split rotary scraper of the rotary split circular conveyer that transports the sorted items. When an error occurs in these split rotation scrapers, it is necessary to immediately stop the operation.

In addition, when the weighing unit measures the weight of the sorted goods transported through the divided rotating circular carrier in the weighing device, the load cell of the weighing unit is very sensitive to external vibration or shock, so external vibrations when measuring the sorted goods Or it is necessary to block the impact.
