COMBINATION WEIGHING DEVICE AND ELECTROMAGNETIC FEEDER

PROBLEM TO BE SOLVED: To provide a combination weighing device avoiding great deviation from a proper amount in a specific head, regarding an article supply amount from a dispersion table to a supply trough. SOLUTION: This combination weighing device 1A is equipped with: the dispersion table 2A for dispersing articles radially, while conveying the articles along a circumferential direction; an electromagnetic feeder 90 for supplying the articles onto the dispersion table 2A; and a plurality of heads HA1-HA9 arranged along the outer circumference of the dispersion table 2A. A domain of a part out of the outer circumference of the dispersion table 2A is specified as a non-discharge domain 30A where the articles are not discharged, and the dispersion table 2A is provided with a circulation route for circulating surplus articles not supplied to the head HA9 among articles conveyed on the dispersion table 2A toward the head HA9 adjacent to the non-discharge domain 30A on one side, toward the head HA1 adjacent to the non-discharge domain 30A on the other side, and the electromagnetic feeder 90 supplies articles onto the circulation route.
