Setting method of starting position of suction band in cigarette weight control system of cigarette making machine

Abstract

The invention provides a setting method of a starting position of a suction band in a cigarette weight control system of a cigarette making machine. The setting method comprises the following steps: automatically identifying the stop and start of the production of the cigarette making machine according to the predefined judgment rule, collecting VE operation parameter data of the cigarette makingmachine and cut tobacco characteristic parameter data in the period before the stop of N-time production, and establishing a prediction model Y being equal to X theta of the starting position of the suction band; reorganizing the VE operation parameter data of a cut tobacco feeding device of the cigarette making machine and the cut tobacco characteristic parameter data in the period before the current production stop to form input data (shown in the description) of current shutdown and carrying out normalization treatment on the input data to obtain normalization input data xnew of the prediction model; calculating to obtain a target position (shown in the description) of the suction band according to the prediction model theta of the starting position of the suction band. When the cigarette making machine is started, the suction band is automatically adjusted to the recommended starting position by a servo motor, so that cigarette elimination at the production start-up stage of the cigarette making machine is reduced.

Description

technical field [0001] The invention relates to intelligent prediction modeling and on-line optimization setting technology for the starting position of the suction ribbon of the cigarette weight control system based on the operating parameter data of the cigarette machine equipment and the shredded tobacco characteristic parameter data. Background technique [0002] With the globalization of the tobacco industry, new laws and regulations, and major changes in the external environment in recent years, China Tobacco is facing increasingly severe competitive pressure and social pressure. Under the premise of ensuring product quality, effectively improving the intelligence level and efficient operation of equipment has become the focus of cigarette factories. Intelligent, that is, production equipment has the functions of perception, analysis, reasoning and decision-making; efficient operation, that is, consume less resources to produce more and better products within a specifi...

AI Technical Summary

Problems solved by technology

The optimal starting position of the ribbon after the cigarette machine is restarted is affected by the operating parameters of the equipment before the shutdown and the characteristic parameters of the shredded tobacco. This method only considers the target position of the collimator (that is, the target position of the ribbon). Other equipment operating parameters that affect the weight of cigarettes are not considered, and the influence of tobacco characteristic parameters is also not considered, resulting in incomplete input parameters of the GPR model, making the GPR model unable to effectively reflect the influence of changes in other equipment operating parameters and tobacco characteristic parameters. The calculated final starting position output value deviates from the ideal starting position
