Combination weighing device

A combination weighing device that repeats a cycle, the cycle includes of supplying products to a plurality of measurement hoppers, measuring weight of supplied products, obtaining combinations of the plurality of measurement hoppers based on a plurality of obtained measurement values, selecting a combination having a measurement value close to a target weight value among the obtained combinations, and discharging the products from the plurality of measurement hoppers of the selected combination, the combination weighing device comprising:

• a storage unit that stores time-series measurement values sequentially acquired by the measurement hoppers;
• a time measurement unit that measures an elapsed time from a timing corresponding to supply of the products to the measurement hoppers until a timing at which the time-series measurement values enter a region considered to be stabilized when the time-series measurement values stored in the storage unit converge to the region considered to be stabilized as a stabilization time until the measurement values become stabilized;
• and
• a selection unit that acquires the stabilization times by the time measurement unit over a plurality of cycles and is configured to select a recommended stabilization time that is the stabilization time in which a predetermined measurement accuracy is configured to be maintained based on a standard deviation of the acquired stabilization times for the plurality of cycles.
