【摘要】：目的使给袋式包装机实现更加精确、平稳的取袋送袋。方法通过建立取袋机构的数学模型,得到包装机允许空间内大、小臂铰链点的位置可行域及初始安装角范围;以封闭矢量法计算出末端执行器运动学参数解析式;应用Matlab编程得到其运动学曲线图谱并进行分析。结果优化后当大臂长l1=360mm、小臂长l2=200 mm、安装角?=30?时末端执行机构的运动学曲线轨迹过渡平稳、没有突变。结论采用结构参数优化后的取袋机构具有良好的运动特性,能够实现更加平稳的取送袋。
[Abstract]:Objective to make the bag packing machine more accurate and stable. Methods by establishing the mathematical model of bag picking mechanism, the feasible range of position and initial installation angle of the hinge point in the permitted space of the packing machine was obtained, and the kinematic parameter analytic formula of the end actuator was calculated by the closed vector method. The kinematics curves were obtained by Matlab programming and analyzed. Results after optimization, when the length of the upper arm is 360mm and the length of the lower arm is 120mm, the angle of installation is 30? The kinematics curve of the time end actuator is stable and has no abrupt change. Conclusion the bag-removal mechanism with optimized structural parameters has good kinematic characteristics and can achieve more stable bag removal.
