Combination weigher with memory hoppers that calculates a first and second optimum combinations for discharge into two different chutes

摘要

A combination weigher of the present invention comprises a first combination weigher unit including a left inner chute, an outer chute, collecting hoppers, weighing hoppers and memory hoppers which are disposed above the left chutes, and a second combination weigher unit including a right inner chute, an outer chute, collecting hoppers, weighing hoppers and memory hoppers which are disposed above the right chutes, and a control unit configured to control the entire combination weigher. The control unit performs a combination process for each combination weigher unit and causes weighing hoppers and memory hoppers which make up of discharge combinations determined in respective combination processes to discharge the objects to be weighed in an inward direction and an outward direction alternately, and to cause the two collecting hoppers to alternately discharge the objects to be weighed according to the discharge, in each combination weigher unit.
