Combinational machine that performs a first combinational calculation among each of a plurality of base groups, discharges them into respective discharge chutes, and then performs a second combinational calculation among the discharged groups

摘要

A combination weigher of the present invention comprises a plurality of base groups into which a plurality of combination hoppers (4) which are circularly arranged are divided; a plurality of collecting chutes (6A to 6D) which are respectively disposed to respectively correspond to the base groups, a plurality of collecting hoppers (7A to 7D) respectively provided at the outlets of the collecting chutes; and a control means (21) wherein the control means (21) is configured to perform: a combination process to determine p discharge groups each including one or more base groups and perform combination calculation for each of the discharge groups to select combination hoppers forming optimal combination, a process to cause the combination hoppers forming optimal combinations in all discharge groups to discharge the objects to be weighed simultaneously; and a process to sequentially select the discharge groups and to cause the collecting hoppers corresponding to the base groups including the combination hoppers forming the optimal combinations in the discharge groups to discharge the objects to be weighed, according to the selected sequence.
