Abstract: Problem To improve the efficiency of a combination weighing operation.
Solution 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 article discharge container 10 has discharge outlets 20 and discharges, from the discharge outlets 20, articles A it is holding. The article conveyance mechanism 30 has plural feeders 40 including a first feeder 41 to an n-th feeder 4n. The plural feeders 40 convey the articles A they have received from the discharge outlets 20. The article detection mechanism 60 has plural sensors 70. The plural sensors 70 include a first sensor 71 to an n-th sensor 7n. The first sensor 71 to the n-th sensor 7n detect the presence of the articles A in the first feeder 41 to the n-th feeder 4n, respectively. The control unit 90 judges whether or not jamming of the articles A is occurring in the discharge 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 discharge outlets 20.
