储柜出料智能控制系统的研究

Study Lockers Discharge Intelligent Control System

摘要: 在制丝工艺中，储柜是十分重要的设备，其出料控制的效果如何，直接关系到后续工序的加香及加料比例，对成品烟丝的吸味及内在质量指标造成严重影响。我车间技术人员采用了超声波测距的方式为系统采集储柜内的物料高度信息，同时结合储柜后一段工序无储料设备的出料速度，通过有效的闭环PID控制算法实现储柜出料速度能实时跟随后端工序设备的物料出料速度，让储柜出料量和后端设备的物料流量实现动态平衡，保证生产过程中的布料均匀性。在实际控制过程中出料控制系统的优劣直接影响到后端工序加香、加料控制的稳定性，本文作者在实际工作中通过研究提出了合理的控制方法，并对相应的控制算法进行了改进完善，在实际的控制过程中取得了较好的效果。

Abstract: In Primary Processing, storage cabinet is a very important equipment, how to control the discharge of its effect is directly related to the proportion of flavoring and the subsequent feeding step, serious impact on the smoke flavor and internal quality indicators of finished tobacco. The plant technicians using ultrasonic ranging system way for collecting material storage cabinet height information, combined with a step-free period after lockers material storage device discharge rate to achieve lockers discharge through effective closed-loop PID control algorithm speed real-time back-end process equipment to follow the material feed rate, so that the quantity of material flow lockers and back-end equipment to achieve the dynamic balance, to ensure the production process of the fabric uniformity. In the actual merits of the discharge control process control system directly affects the back-end process flavoring, feeding stability control, the author in practical work through the study proposes reasonable control methods, and the corresponding control algorithm improved, and achieved good results in the actual control process.
