Japanese: 選別秤 - せんべつはかり(英語表記)sorting scale
Sorting scale - Sorting scale (English spelling)
A device that automatically separates large quantities of products according to their mass. It separates individual products, boxes containing a certain number of items, or bags containing a specified amount of items into heavy, light, and heavy, and is also used to sort agricultural products such as fruits and eggs. The structure varies depending on the shape and properties of the object being measured, but a lever is used to detect the load. The lever is set so that it is balanced horizontally when an object of a standard mass is placed on it, and the inclination of the lever according to the weight is used to sort the object. Mechanical or electrical methods are used for sorting. Since detection using a lever has a slow response speed, some types use a helical spring for optical detection. This is said to have a measurement time of 0.05 to 0.5 seconds per measurement, improving sorting ability.

Japanese:
大量の製品を質量の大小によって,自動的により分ける装置。個々の製品,一定個数の箱詰,所定量の袋詰などについて,正,軽,重の仕分けをするもので,果実や卵などの農産物の選別にも使用される。被測定物の形状,性質などによって構造は異なるが,荷重の検出にはてこが用いられている。てこは標準の質量のものが載せられたとき,水平に釣合うように設定されており,軽重に応じるてこの傾きを利用して仕分けする。仕分けには機械的または電気的な方法が採用される。てこによる検出は応答速度が遅いので,弦巻ばねを用いて光学的に検出するものがある。これは1回の計測時間が 0.05~0.5秒といわれ,選別能力は向上する。
