摘　　要：针对目前中小型啤酒企业的瓦楞纸板卸垛作业仍依赖手工完成,存在耗时耗力的问题,课题组采用系统化设计方法,设计了一种新型的龙门式瓦楞纸板卸垛机。采用电缸和气缸组合驱动,实现高精度分步提取纸板的功能;采用气缸连杆机构,设计了一种摆动的纸板打落机构;利用ANSYS Workbench软件对关键零部件进行有限元分析,得到了等效应力云图和变形云图,验证了机构的稳定性和强度要求;并进一步对机架进行模态分析和谐响应分析,得到了前6阶模态参数和位移频率响应曲线。结果表明:当工作频率为17 Hz时,机架易发生共振,频率响应急剧增大,形成峰值。该卸垛机能正常完成卸垛工作,提高了生产效率,降低了成本。At present,depalletizing of corrugated board in small and medium-sized breweries still rely on manual work.In order to solve the time-consuming and labor-consuming problem of manual depalletizing,a new type of gantry corrugated cardboard depalletizing machine had been designed adopting the method of system optimization. Realized the function of taking out corrugated cardboard step-by-step with high accuracy by combined driving of electric cylinder and air cylinder. An air cylinder linkage mechanism was used to design cardboard falling mechanism. Finite element analysis of the key components was carried out by using ANSYS Workbench software. The equivalent stress nephogram and deformation nephogram were obtained,which verified the stability and strength requirements of the mechanism. Further modal analysis and harmonic response analysis were performed on the frame,and the first 6 orders modal parameters and displacement frequency response curves were obtained. The results show that the frame is prone to resonance,and the frequency response increases sharply,forming a peak when the working frequency is 17 Hz. The depalletizing machine can complete depalletizing,improve the production efficiency and reduce costs.
