Abstract:
1. A combination weighing device comprising: a dispersion feeder configured to convey and disperse supplied articles; a plurality of radial feeders arranged radially outward from and below an outer periphery of the dispersion feeder, the radial feeders being configured to receive and further convey the articles discharged from the dispersion feeder; a plurality of weighing hoppers configured to receive the articles discharged from the radial feeders; a setting unit configured to set a combination target weight and set initial parameters related to the articles; a dispersion control system configured to adjust a driving parameter for the dispersion feeder so that a discharge amount on each discharge from the dispersion feeder to the radial feeders coincides with the combination target weight; a radial control system configured to adjust a drive parameter for each of the radial feeders so that a discharge amount on each discharge from a plurality of the radial feeders selected in a combination coincides with the combination target weight; and a first control unit configured to calculate the drive parameter for the dispersion feeder and the drive parameter for the radial feeders based on the initial parameters related to the articles which include at least layer thickness parameters related to an expected layer thickness of the articles on the dispersion feeder and an expected layer thickness of the articles on the radial feeders while being conveyed, and set each of the calculated drive parameters as an initial value for the respective one of the dispersion control system and the radial control-system.
