Abstract: A combination weighing device (1) performs combination weighing of at least two different articles, weighing hoppers (5) and booster hoppers (6) are divided into at least two groups on the basis of types of the articles, a controller (1) sets each of the groups to either a first mode or a second mode, in the group set to the first mode, the articles retained in the weighing hopper (5) are discharged to a receiver (9) via the booster hopper (6), and in the group set to the second mode, the articles retained in the weighing hopper (5) are discharged to either the booster hopper (6) or the receiver (9).

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.
