基于PLC控制的卷制辅料剩余量精准控制的设计

Design of Precise Control of Residual Amount of Cigarette Rolling Material Based on PLC Control

摘要: GDX6S为GD公司最新软包设备，设计车速600包/分。该设备在实际应用过程中，发现局部功能控制存在不足。主要表现为：(1) 辅料卷(商标卷、内衬卷)剩余量控制不精准，消耗大，剩余量调整麻烦、耗时；(2) 废烟收集带控制方式设计不合理(故障率高)。针对这些缺陷，应用PLC控制技术，依靠自身技术力量，对设备进行技术攻关，首次在国内独立、自主完成X6S辅料卷剩余量精准控制功能综合改造。该项目主要包括商标卷、内衬卷拼接后剩余量精准控制功能和废品烟支收集带智能控制辆大功能。实施该项目改造，可进一步提升了设备技术性能，对降低辅料消耗，提高设备运行效率提供可靠的技术保障。目前，该项目已在B3#-X6S设备上设施改造，至今已可靠、稳定运行一年多，下一步将在其余设备上推广应用。

Abstract: GDX6S is the latest soft-pack equipment of GD Company, with a design speed of 600 packs/min. In the actual application of this equipment, some functional control deficiencies were found. The main manifestations are: (1) the control of the residual amount of auxiliary material rolls (trademark rolls, inner liner rolls) is inaccurate, the consumption is large, and the adjustment of the residual amount is troublesome and time-consuming; (2) the control mode of the waste cigarette collection belt is not reasonably designed (high failure rate). In response to these defects, PLC control technology was applied, and relying on its own technical strength, the equipment was technically tackled. For the first time in China, the comprehensive transformation of the X6S auxiliary material roll residual amount precise control function was completed independently and autonomously. The project mainly includes the precise control function of the residual amount after the trademark rolls and inner liner rolls are spliced and the intelligent control function of the waste cigarette collection belt. The implementation of this project transformation can further improve the technical performance of the equipment and provide reliable technical guarantee for reducing auxiliary material consumption and improving equipment operating efficiency. Currently, the project has been implemented on equipment B3#-X6S, and has been operating reliably and stably for over a year. The next step is to extend its application to other equipment.
