Abstract: Problem To improve the efficiency of a combination weighing operation.
An article conveyance device 110 includes an article discharge container 10, an article conveyance mechanism 30, an article detection mechanism 60, and a control unit 90. The container 10 has outlets 20 to discharge articles A. The article conveyance mechanism 30 has feeders 40 including a first feeder 41 to an n-th feeder 4n configured to convey the articles A. The article detection mechanism 60 has sensors 70 including a first sensor 71 to an n-th sensor 7n configured to detect the articles A in the first feeder 41 to the n-th feeder 4n, respectively. The control unit 90 judges whether jamming of the articles A is occurring in the outlets 20 based on output of the article detection mechanism 60. The control unit 90 increases a conveyance intensity of some feeders receiving the articles A from places where the jamming is occurring in the outlets 20.
