However, the conventional combination weighing device has the following problems.
That is, in the combination weighing / counting device disclosed in the above publication, a plurality of partitions are provided at the upper stage of the collecting hopper to prevent the objects to be weighed in the circumferential direction. However, since the partition portion is not formed in consideration of the position of each weighing hopper, there is a possibility that diffusion of the object to be weighed in the circumferential direction cannot be effectively prevented depending on the positional relationship between the weighing hopper and the partition portion.

  An object of the present invention is to effectively regulate the movement of the objects to be weighed discharged from the weighing hopper in the circumferential direction, and to discharge the objects to be weighed for one weighing cycle from the collecting hopper in the shortest time.
