Industrial control computer (IPC)-based cigarette making machine tobacco rod weight control and quality detection integrated device and method

Abstract

The invention relates to the technical field of tobacco industry industrial process control and on-line detection and discloses an industrial control computer (IPC)-based cigarette making machine tobacco rod weight control and quality detection integrated device and method. The device utilizes an IPC system and its module and an EtherCAT bus to realize tobacco rod weight control and quality detection on a platform, and comprises a data processing unit, a weight control unit IO module, a quality detection unit IO module, a presignal processing unit, a gas source stabilization unit, a human-computer interface and a communication unit. The weight control unit IO module and the quality detection unit IO module acquire tobacco rod weight control and quality detection related data. The EtherCAT bus protocol is transmitted to the data processing unit. The data processing unit carries out operation on the data and transmits the result to the weight control unit IO module and the quality detection unit IO module, and the data is output. The device is free of a self-researched circuit board and is convenient for maintenance. The device improves tobacco rod weight short period standard deviation technology indexes and reduces tobacco rod removal error rate and removal missing rate. The device realizes weight control and quality detection in one unit and has good cooperativity.

Description

technical field [0001] The invention relates to industrial process control and on-line detection technology in the tobacco industry, in particular to an integrated device and method for cigarette weight control and quality detection using IPC in a cigarette set. Background technique [0002] In the production process of cigarettes, data such as weight, short end, air leakage, air permeability, and appearance of cigarettes are all very important technical indicators in the production process of cigarettes, and these indicators determine the grade of cigarettes. Especially at present, with the development of tobacco equipment, the production capacity of tobacco factories has met the needs of the current stage. With the improvement of consumers' understanding of cigarettes and their awareness of rights protection, the quality of cigarettes is becoming more and more important, which determines the quality of cigarettes. Whether a tobacco brand is good or bad, how to improve the ...

AI Technical Summary

Problems solved by technology

[0003] The current weight control system and quality inspection system used on cigarette equipment are all realized by self-developed circuit boards. very inconvenient

Most of these equipments are realized by decades-old technology, backward technology, poor stability, high failure rate, single function, unable to meet the requirements of high-speed production of cigarettes, resulting in large fluctuations in the weight of cigarettes, unqualified cigarettes missing The rate and false rejection rate are high, especially for cigarette leakage detection, the air source stability is poor, and false rejections and missed rejections often occur

Moreover, in the existing cigarette production line, the weight control system and the quality inspection system are two sets of independent equipment, there is no connection between them, and they are irrelevant to each other, which results in no communication between the information available in the two equipment, and repeated Wiring, low utilization
