Combination weighing device with multiple hoppers and modes

A combination weighing device that performs combination weighing of at least two different articles, the device comprising:

• a plurality of weighing hoppers that temporarily retain the articles and acquire weighing values of the retained articles before discharging the articles downstream;
• a plurality of booster hoppers that are arranged downstream of the weighing hoppers and temporarily retain the articles discharged from the weighing hoppers before discharging the articles downstream;
• a receiver that receives the articles discharged from the weighing hoppers or the booster hoppers;
• and
• a controller that performs combination weighing on the basis of the acquired weighing values and discharges the articles constituting a target from the weighing hoppers or the booster hoppers, wherein
• the weighing hoppers and the booster hoppers are divided into at least two groups on the basis of types of the articles,
• the controller sets each of the groups to either a first mode or a second mode on the basis of the types of the articles,
• in the group set to the first mode, the articles retained in a first weighing hopper are discharged to the receiver via a first booster hopper, and
• in the group set to the second mode, the articles retained in a second weighing hopper are discharged to either a second booster hopper or the receiver.
