<p>Provided is a combination weigher capable of reducing a batch time of objects to be weighed on a collecting chute and of a high-speed operation, irrespective of characteristic or the like of the objects to be weighed. The combination weigher of the present invention includes a plurality of upper collecting chutes (6a, 6b) disposed below weighing hoppers (4), a plurality of upper collecting hoppers (7a, 7b) respectively provided at discharge outlets of the upper collecting chutes (6a, 6b), a lower collecting chute (8) provided below the upper collecting hoppers (7a, 7b), a lower collecting hopper (9) provided at a discharge outlet of the lower collecting chute (8), and a control unit (20) which repeatedly performs a combination process to determine one discharge combination of the weighing hoppers (4), a discharge process for discharging the objects to be weighed from the weighing hoppers (4) belonging to the discharge combination onto the upper collecting chutes (6a, 6b), and a discharge process for discharging the objects to be weighed simultaneously from the upper collecting hoppers (7a, 7b), and a discharge process for discharging the objects to be weighed from the lower collecting hopper (9).</p> |
