摘    要
本次设计，主要目的是完成螺旋式滚筒硬币分离计数包装机的结构设计，技术设计和性能优化，目的是把不同面值的硬币通过一系列机构分离计数，最终进入包装机构进行包装。本次设计系统地分析了整体方案及各结构，在对设计任务和目的总体把握的情况下，进行整机结构、原动机构、传动机构、分离系统、计数装置和包装机构的设计。由于装置分离的精确性和计数的准确性是一个至关重要的性能要求，因此需要对滚筒转速、传动形式、收集形式进行分析选取，分析工作的实际情况进行编程，根据安装条件选取合适的传感器，通过实验结果做出选择，同时选取最佳的包装方式，保证最终效果。还需要站在全局角度进行装置的可靠性，加工工艺性和经济性分析，使得装置得到优化。并且在实际工程模式下，充分考虑加工工艺性和经济性之间的关系，制定合理的加工工艺，保证加工精度，同时运用合理的工程管理方法指导生产实践。

ABSTRACT
The main purpose of this graduation design is to complete the structural design of the spiral drum coin separation and counting packaging machine, technical design and optimization, separate the coins with different face values and count the final packaging. This design systematically analyzes the overall plan and the various structures. In the case of the overall grasp of the design task and purpose, the design of the whole machine structure, the original mechanism, the transmission mechanism, the separation system and the counting device are carried out. As the accuracy of the separation of the device and the accuracy of the count is a critical performance requirement, it is necessary to select the rotating speed of the cylinder, choose the experimental results and select the best way of packing. From the global perspective, the reliability, manufacturability and economy of the device are analyzed, and the device is optimized. In the actual project model, the relationship between processing technology and economy is fully considered, the reasonable processing technology is formulated, and the production practice is guided by reasonable engineering management methods.
