Glycerin application error-proof control method, device and system

Abstract

The invention discloses a glycerin application error prevention control method, device and system. Wherein, when it is detected that the filter rod forming machine is in the running state, it is detected whether the glycerin application device is in the closed state; if the glycerin application device is in the closed state, then query whether the first timer has been started; if the first timer has not been started, then Start the first timer, so that the first timer starts counting, and instructs the alarm device to give an alarm, and then performs the step of detecting whether the glycerin application device is in a closed state; if the first timer has started, then judge the timing of the first timer Whether the time reaches the first delay time; if the timing time has not reached the first delay time, then perform the step of detecting whether the glycerin application device is in the closed state; if the timing time reaches the first delay time, then close the first timer , instruct the alarm device to stop the alarm, and instruct the filter rod forming machine to stop. Thereby, it can effectively prevent unqualified filter rods from flowing into the next process.

Description

technical field [0001] The invention relates to the field of forming cigarette filter rods, in particular to a glycerin application error prevention control method, device and system. Background technique [0002] KDF2 Filter Rod Forming Machine is a common cigarette filter rod production equipment in the tobacco industry, which is usually composed of tow opening (AF) and filter rod forming (KDF) parts. In the AF tow pretreatment process, the equipment opens the tow, and applies glycerol triacetate (referred to as glycerol) on the opened tow to increase the hardness of the filter rod and trap the harmful components of the smoke to meet the Assembly process requirements. During the production process, the glycerin applicator atomizes and sprays glycerin from the glycerin tank onto the opened tow. To test how much glycerin is applied to a filter stick, equipment operators compare the weight of a filter stick with no glycerin applied (called a dry stick) and a filter stick wi...

AI Technical Summary

Problems solved by technology

[0004] 1. The operator forgets to turn on the glycerin application device after closing the glycerin application device to sample the dry stick, resulting in the production of a large number of dry sticks that flow into the next process

[0005] 2. During the operation of the filter rod forming machine, when the glycerin application device fails and suddenly shuts down, the filter rod forming machine continues to run, but lacks an alarm signal, and the operator cannot detect the existence of the fault in time, resulting in the production of a large number of dry rods that flow into the next Process

[0006] 3. During the operation of the filter rod forming machine, the glycerin application pipeline or part of the atomization nozzle is blocked, causing the pressure sensor to display a value higher or lower than the set value, which will lead to uneven glycerin application and produce a large number of unqualified filter rods Flow into the next process
