Design of a Batch Sampling Device for Cigarettes Based on PLC Technology

摘要

In the cigarette production industry, the automatic cigarette sampling device varies. This paper introduces a new batch sampling device based on PLC technology, which involves mainly the system's mechanical structure, its operating principle, the PLC program control flow and so on. Sampling by the device is completely mechanical, which means it's easy to operate and is with good stability, safety and reliability. Meanwhile, it does not interfere with or damage the sample flow. So it can be used for non-destructive batch sampling of rod-like products such as large flow of cigarettes in high-speed production environment, which greatly reduces the labour intensity of quality checkers by improving the automation of cigarette testing, resulting in great industrial application value.
