Cigarette air leakage defect on-line diagnosis method

Abstract

The invention relates to a cigarette air leakage defect on-line diagnosis method. The invention comprises: a cigarette making machine electric control system and a data acquisition device, which are connected to an industrial Ethernet; an application server, which is used for storing data acquired by the data acquisition device into a relational database; a relational database server, which is used for storing statistical results of a gas leakage defect judgment knowledge base, an analysis model and big data analysis; a real-time historical database, which is used for storing original data and change values of collected indexes; and a data analysis server, which is used for cleaning and analyzing gas leakage defect indexes and factor index data: further analyzing whether the data of related factors are varied or not by utilizing an established data analysis model, and if the data of the related factors are varied, according to parameters, positioning links and point locations with abnormal gas leakage detection values, and pushing diagnosis information to equipment and process personnel to adjust equipment and process parameters. According to the method, the control level of the technological process can be greatly improved, and a foundation can be laid for intelligent manufacturing of cigarette procedures.

Description

technical field [0001] The invention belongs to the technical field of cigarette production technology in the tobacco industry and the technical field of intelligent detection, and more specifically relates to an online diagnosis method for air leakage defects in cigarettes. Background technique [0002] During the cigarette manufacturing process, the tipping paper is glued by rubber roller smearing or spraying, and then the glued tipping paper is transported and cut, and the filter tip and cigarette paper are glued together to form a complete cigarette. During the process of this process, due to the characteristics of the tipping paper, the characteristics of the glue, and the changes in the process and equipment conditions of the transportation and rubbing links, there is a certain probability that air leakage cigarettes will occur (that is, the tipping paper and the cigarette paper and the filter rod are not completely glued. Together), this kind of leaking cigarettes wi...

Problems solved by technology

Due to factors such as the set value of the rejection limit, the excessive rejection amount, and the stability of the detector, the current air leakage detector of the cigarette machine cannot ensure that there is no leakage, and the current air leakage detector only realizes the defect rejection or alarm function, and cannot Real-time and accurate positioning of the scope and cause of abnormal air leakage (such as auxiliary material factors, equipment factors, process index fluctuations, etc.), it is inevitable to cause problems such as batch product quality defects and increased production process losses, and it is impossible to truly achieve the goal of improving production and manufacturing levels
