ROTATING TYPE WEIGHING APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a rotating type weighing apparatus frequently acquiring a sufficiently stable zero point signal. SOLUTION: A plurality of measuring devices 2-1 through 2-n are disposed rotatably around the rotation center. A carrying-in position A where articles are sequentially carried into the measuring devices 2-1 through 2-n and a carrying-out position B where articles are sequentially carried out of the measuring devices 2-1 through 2-n are disposed at a distance in a predetermined direction on a rotation trajectory drawn by rotation of the measuring devices 2-1 through 2-n in the predetermined direction. A zero point weight signal is compensated based on the deviation of output acquired by each of the measuring devices 2-1 through 2-n whenever each of the measuring devices 2-1 through 2-n rotates a plurality of times from a carrying out position B to carrying in position A. The compensation is performed while the amount of deviation is reduced. COPYRIGHT: (C)2011,JPO&INPIT
