| 目的 为了丰富枕式包装机的包装种类，提高其包装精度和包装效率，对现有机器中电子凸轮飞剪算法进行改进。方法 根据枕式包装机的工艺流程，建立电子凸轮飞剪的数学模型，设计五次多项式运动控制算法，实现送料轴、送膜轴、切刀轴的协调同步运行，然后进行控制系统的设计。结果 通过测试结果可以看出，随着包装速度的增加和包装长度的减少，包装的合格率会有所降低，但五次多项式规划设计的电子凸轮曲线具有良好的连续性和柔性，避免了刚性冲击和机械振动，在包装允许的误差±1 mm的范围内，包装合格率始终为100%，有效提高了控制精度。结论 设计的电子凸轮曲线完全满足生产工艺要求，实际测试证实了基于电子凸轮飞剪的控制系统的可靠性与稳定性，也证实了运动控制算法的优越性。 |

| The work aims to improve the electronic cam flying shear algorithm in the existing machine in order to enrich the packing types of pillow packing machine and improve its packing precision and efficiency. According to the process flow of pillow packing machine, the mathematical model of electronic cam flying shear was established, and the quintic polynomial motion control algorithm was designed to realize the coordinated and synchronous operation of feeding shaft, film feeding shaft and cutter shaft. Then, the control system was designed. According to the test results, with the increase of the packing speed and decrease of packing length, the qualified packing rate was reduced, but the electronic cam curve designed by the quintic polynomial planning had good continuity and flexibility, avoiding the rigid and mechanical vibration. Within the allowable error of ±1 mm, the qualified packing rate was always 100%, which effectively improved the control accuracy. The electronic cam curve designed completely meets the requirements of production technology. The actual test proves the reliability and stability of the control system based on electronic cam flying shear, and also proves the superiority of the motion control algorithm. |
