COMBINATION WEIGHING APPARATUS

PROBLEM TO BE SOLVED: To provide a combination weighing apparatus, capable of preventing or minimizing reductions in weighing accuracy due to noise caused by the rotation of a spiral member. SOLUTION: The combination weighing apparatus 1 includes: a dispersing table 2 for radially dispersing articles loaded thereinto from above; a plurality of transfer means 3 arranged on the circumference of the periphery of the dispersing table 2; and a plurality of weighing hoppers 5 arranged on the circumference of the periphery of the plurality of transfer means 3. The transfer means 3 includes: a trough 10 having an internal end part 20 positioned below the dispersing table 2, an external end part 21 positioned above the weighing hoppers 5, and an open upper surface; the spiral member 11 driven to rotate to transfer articles supplied for the internal end part 20 from the dispersing table 2 toward the external end part 21; and a support means 51, provided in a midpoint between the internal end part 20 and the external end part 21 for supporting the spiral member 11.
