Abstract
A control system for a cigarette making and pack aging system including a cigarette making machine, a cigarette packaging machine with a variable operation speed, and a reservoir mechanism provided between the cigarette making machine and the cigarette packaging machine, a current reserve amount calculating unit for calculating a current reserve amount in the reservoir mechanism, an intermediate reserve amount calculating unit for calculating an intermediate reserve amount, a desired value setting unit for setting a maximum reserve amount and a minimum reserve amount of the reservoir mechanism on the basis of the intermediate reserve amount, a comparison unit for comparing the current reserve amount with the maximum reserve amount and the minimum reserve amount, and a speed control unit for controlling the speed of the packaging machine on the basis of a comparison result by the comparison unit. The intermediate reserve amount is updated periodically with a predetermined period of time is such a way that a new value of the intermediate reserve amount for the following period of time is based on the average down time of the cigarette making machine and that of the cigarette packagin…
