Analysis of Causes on High False Rejection Rate of Dark Tipping Paper Connector of ZJ118 Cigarette Machine

Abstract

ZJ118 cigarette making and tipping machine combination is widely promoted in the industry because of its fast speed of production and stable operation. However, with the development of process requirements and the diversification of cigarette types, when producing cigarettes using dark tipping paper, the false rejection rate of tipping paper joint detection system is higher than the normal level. Given this situation, taking Black Middle cigarettes of a tobacco company as an example, the engineer spent 3 months to analyze its causes according to the characteristics of the detection system through on-site statistical investigation progressively, and finally concluded that the problem lay in the mismatch between the transmittance of tipping paper and the detection system. Dark tipping paper due to its low light transmittance, caused high false rejection rate. This article elaborates this in detail.
