【摘要】 我国作为世界上第5大包装机械生产国和第2大包装机械进口国,国内瓦楞纸箱印刷模切机科技含量普遍较低,存在印刷速度低,套印精度低的问题,本文以广东省重大专项《高精度数控多色印刷模切设备及其数字化设计制造共性技术研究》为课题背景,深入研究共轴印刷模切机的机械特性,采用伺服技术研制高精度多色瓦楞纸无轴印刷模切机,提高印刷速度以及套印精度,实现产品技术升级,提高国内企业在瓦楞纸印刷模切机方面的制造水平,具有十分重要意义。本文在分析传统的瓦楞纸共轴印刷模切机传动机构及其原理的基础上,针对瓦楞纸无轴印刷模切机传动结构设计了三个方案并作出分析和比较,选出了最适合本项目要求的传动结构设计。根据项目对印刷速度、套印精度、需实现的伺服功能以及控制轴数要求等,分别设计了Simotion运动控制方案、SYNAX运动控制方案、基于TwinCAT与EtherCAT技术运动控制方案三个伺服控制方案,并分别从控制方案的硬件控制器、总线、驱动器以及控制方案的软件等各方面进行比较,最终选用从硬件灵活性、兼容性以及软件开放性都最好的基于TwinCAT与EtherCAT技术运动控制方案。在硬件方面,完成了瓦楞纸无轴印刷模切机伺服电机选型,设计了电控柜的布置图以及了相应的电器原理、IO分布。在软件方面,分析了瓦楞纸无轴印刷模切机的功能需求,规划了其人机交互界面。针对印刷模切机的关键技术——同步技术以及凸轮技术,在软件开发平台TwinCAT中提供了相应的解决方案,进行了程序设计并进行了仿真实验。本文已完成对数字式高速多轴印刷模切机伺服控制系统的设计,所有设计已交付合作企业,目前项目已完成机构改造,正处于伺服安装阶段。本文完成了数字式高速多轴印刷模切机伺服控制系统的设计,为瓦楞纸无轴印刷模切机的技术升级提供了宝贵的经验,对于其后续研究提供了进一步的研究思路。更多还原

【Abstract】 As the 5th largest packaging machinery producer and 2nd largest importer of packaging machinery in the world, domestic corrugated box printing and die cutting machine is generally low technological content, low speed and low precision of chromatography. Based on the traditional printing and die cutting machine, this thesis aims at developing high-precision multi-color corrugated shaftless printing and die cutting machine by adopting servo technology. It improves the printing speed and chromatography accuracy, achieve technological upgrading of products, improves the Manufacturing level of the printing and die cutting machines of the domestic enterprises, has very important significance.Based on the analysis of transmission structures of traditional printing and die cutting machine, three transmission structure designs are made and analyzed, the best fit one is adopted. According to the requirements of printing speed, chromatography accuracy and servo functions of the project, three servo motion control platform designs, Siemens Simotion motion control platform, Rexroth SYNAX motion control platform, EtherCAT & TwinCAT technology motion control platform are made and analyzed. The platforms are compared in the aspects of controller,fieldbus, driver and software, EtherCAT & TwinCAT technology motion control platform is chosen for its hardware flexibility, hardware compatibility and open software development environment. In terms of hardware, the servo motor slection is made, the cabinet layout and electrical principles as well as IO distribution are designed. In terms of software, the function requirements are analyzed and the human machine interface is planned. For the key technologies of the printing and die cutting machine, synchronization and cam technology, the Corresponding solutions and programs are provided, the simulation test are complished on the TwinCAT, the software development environment.The solution is under implementation by the Joint venture, the stucture reformation is finished and the servo installation is undergoing. The disingn of numerical high speed multi-axis printing and die cutting machine servo control system is completed which provides very Precious experience for the upgrade of the printing and die cutting machine and some ideas for further researsh.更多还原
