Embodiment 1

[0034] Silk-making process quality monitoring system of the present invention comprises

[0035] Index formulation unit: analyze the historical data in the central control data system, obtain the indicators that affect the quality of the silk-making process, formulate the benchmark value of each indicator, and set the upper limit and lower limit of the SPC control of the indicator;

[0036] The data acquisition unit sets the batches for tracking production, and collects the index values ​​of the batches of products from the central control data system during the silk making process;

[0037] The data analysis unit analyzes the collected index value and compares it with the benchmark value of the index obtained in the step (1), when the collected index value exceeds the upper limit of the SPC control of the index or lower limit, alarm display;

[0038] The result judging unit performs SPC judgment after the silk making process is completed, and forms the SPC judgment result. ...

Embodiment 2

[0045] On the basis of the silk-making process quality monitoring system described in Example 1, an evaluation unit is also included. After the production of the batch is completed, the batch is evaluated and the quality of the batch is quantified.

[0046] A kind of silk making process quality monitoring method described in the present embodiment, comprises the following steps:

[0047] (1) Analyze the historical data of the past two years in the central control data system to obtain indicators that affect the quality of the silk-making process, such as figure 2 shown. At the same time, through preliminary screening, a large number of parameters irrelevant to batch quality are eliminated, reducing the subjectivity of data submitted by craftsmen and reducing the workload of staff. Then, according to the obtained indicators that affect the quality of the silk-making process, the benchmark value of each indicator is formulated, and the upper and lower limits of the SPC control...

Abstract

The invention relates to a quality monitoring system and a method of a tobacco primary process. The quality monitoring system of the tobacco primary process comprises an index formulating unit, a data collection unit, a data analysis unit and a result determination unit; the collected data is modeled and analyzed on the basis of a tobacco primary process center control data system, so that the indexes according with current tobacco requirements, device processing capacity and processing direction are obtained, and the indexes are subjected to SPC (statistical process control) tracking determination. According to the technical scheme, the technical problem that a tobacco primary process parameter in the prior art cannot objectively reflect an actual production condition is effectively avoided. The quality monitoring method and the system are capable of monitoring and automatically analyzing the tobacco primary process.

Description

technical field [0001] The invention relates to a quality monitoring system and method, in particular to a quality monitoring system and method of silk-making process in a cigarette factory, and belongs to the technical field. Background technique [0002] In the cigarette industry, the shredded process is very important. The most concerned thing in the shredded process is to ensure the stability and controllability of production quality. In the whole production process, there are a large number of parameters that affect the quality of shredded tobacco, such as ambient temperature, Atmospheric moisture content, atmospheric pressure, etc. In China, although there are cigarette industry standards, due to the differences in the environment, quality of tobacco leaves, equipment capabilities, and processing methods in different places, each enterprise has different control parameters in its silk production process. How to control silk quality more efficiently, accurately and con...
