PURPOSE:To hold measurement precision invariably high, by lowering a body to be measured according to the inclination of a conveyor pawl, and mounting the body to be measured on a conveyor belt and moving it in a floating state over the conveyor pawl. CONSTITUTION:When the conveyor pawl 3 mounting a work W passes on a scale table 5, scaling is carried out before and after the work W is mounted and signals of both measured values are inputted to a control device. Then, the weight difference between both measured values is sorted on the basis of specific weight section stages and a discharge shoot 9 is commanded to lower the tip of a pawl plate 3a according to the selected stage. Consequently, the conveyor pawl 3 mounting the work W again by passing through a scale device 4 drops the work W on the selected discharge shoot 9 from above and the work is discharged to the side of the conveyor 2. Thus, since the measurement is taken by utilizing the weight difference, the weight of the conveyor belt 3 as a conveyor container does not relate to the measurement precision. |
