Description
図１６は、従来のコンベヤスケール１０３を示す。コンベヤスケール１０３は、ベルトコンベヤで連続して輸送されるばらの状態の各種原材料や製品１０１などの質量とベルト１０２の速度を電気的に検出し、それらを演算して輸送量を計量する。このコンベヤスケール１０３において、計量ローラ１０４を介してレバー（荷重受台）１０５に作用する垂直力をＦｙ、水平力をＦｘ、ロードセル１０６に作用する力をＰ、支点Ｏと計量ローラ１０４及びロードセル１０６との水平距離を夫々ａ，ｂとし、支点Ｏと計量ローラ１０４の回転中心までの高さ方向距離をｈとすると、支点Ｏ回りのモーメントの釣り合いより、 FIG. 16 shows a conventional conveyor scale 103. The conveyor scale 103 electrically detects the masses of various raw materials or products 101 in a state of being continuously transported by the belt conveyor and the speed of the belt 102, calculates them, and measures the transport amount. In this conveyor scale 103, the vertical force acting on the lever (load receiving base) 105 via the measuring roller 104 is Fy, the horizontal force is Fx, the force acting on the load cell 106 is P, the fulcrum O, the measuring roller 104 and the load cell. If the horizontal distance from the fulcrum 106 is a and b and the distance in the height direction from the fulcrum O to the rotation center of the measuring roller 104 is h, the moment balance around the fulcrum O is
上式（１）でＦｙがベルト１０２上の原材料等の質量Ｗに比例し、右辺第２項が第１項に比べて十分小さいか、一定であればＰ∝（ａ／ｂ）Ｗと見做すことができ正確な計量ができる。
In the above equation (1), if Fy is proportional to the mass W of the raw material or the like on the belt 102 and the second term on the right side is sufficiently smaller than the first term or constant, it is regarded as P∝ (a / b) W. It can be deceived and accurate weighing is possible.
