Design and application of the control device of the cascading waste rejection valve of cigarette maker

In order to solve the problem that the defective cigarettes were mixed into the finished cigarettes under the single waste rejection valve mode of cigarette machine, the production speed was fast, the performance of the waste rejection valve was reduced, the drive module of the waste rejection valve was faulty, the signal circuit was broken, the peripheral pressure was too small, and so on. This paper provides a cigarette maker’s cascading among N waste rejection valves and its control device. After the first waste rejection valve acts, waste into the waste rejection valve after excluding effectiveness is monitored, when rejection fails, issue instructions in the next location continue to reject the waste, this makes all cigarette maker’s waste rejection valves can be correlated cascade control. The system failure rate is the product of the failure rates of all the scrap valves. After the online product verification, the results show that the failure rate of the cascade control is only 0.84%, which is significantly lower than that of the single waste rejection valve mode and has a significant promotion effect on quality assurance.
