PURPOSE:To prevent the supply of extreme massive object, by determining whether a computed feeding capacity parameter is within a specified range based on the current feeding capacity parameter to decide the new subsequent feeding capacity parameter according to the result of the judgement. CONSTITUTION:Measured values of respective weighing devices 171-17n of weighing hoppers 161-16n are fed to arithmetic circuits 291-29n which calculate a feeding capacity parameter of feeders to bring the feed from a feeder at the subsequent supply close to a specified value. Judging circuits 401-40n compare the resulting feeding capacity parameter with the current feeding force parameter and when the calculated feeding capacity parameter is within a specified range set based on the current feeding capacity parameter, it is used as a new feeding capacity parameter intact. But otherwise, depending on the size of both the parameters, the upper limit value or lower limit value within the specified range is outputted as a new feeding capacity parameter. According to the output of the judging circuit, the driving of individual feeders is controlled.
