用于不同规格瓷器包装的通用自动化系统设计

Design of A Universal Automation System for Packaging Porcelain of Different Specifications

目的根据瓷器怕摔易碎的特性,针对各种不同规格瓷器的包装工艺,设计一种通用的瓷器即时包装自动化系统。方法为了适应不同规格的瓷器包装,该系统采用红外扫描的方式检测瓷器外形,设计3种全自动工作模式。采用笛卡尔坐标系原理,应用旋转平台和双自由度喷枪实现了瓷器的三维全方面包装。采用大功率舵机精确控制喷枪的喷发时刻和喷发强度,该系统还具有限位报警和发泡剂流量控制的功能,保证系统工作的稳定性,提高系统的实用性。结果通过流量控制试验,解决了喷枪流量稳定性差和包装层衔接不均匀问题,实验结果表明,喷枪开关角度越大,喷发直径越大,发泡剂喷发效果越好。现场瓷器包装实验,验证了该系统的有效性。结论该包装系统打破了现在包装机器只能包装固定外形瓷器的格局,实现了一机通用,实现了现场即时包装。该系统自动化程度高,包装质量好,包装效率高,成本低,提高了包装行业的经济效益。

The work aims to design a universal automatic packaging system for porcelain according to the packaging technology of porcelain with different specifications in view of easy breaking of porcelain after falling. In order to adapt to porcelain packages with different specifications, the system used infrared scanning to detect the shape of porcelain and designed 3 automatic working modes. Based on the principle of Cartesian coordinate system, a rotating platform and a two-degree-of-freedom airbrush were used to realize the 3D full packing of porcelain. The high-power steering gear was used to accurately control the eruption time and intensity of the airbrush. The system also had the function of limit alarm and blowing agent flow control, which ensured the stability of the system and improved the practicability of the system. Through the flow control test, the problems of poor flow stability of airbrush and uneven connection of packaging layer were solved. The results showed that the bigger the angle of airbrush was, the bigger the diameter of spray gun was and the better the effect of blowing agent was. The effectiveness of the system was verified by the on-site porcelain packaging experiments. The packaging system breaks the current pattern that the packaging machine can only pack porcelain with fixed shape, and realizes one machine for general use and instant packaging on site. The system has the advantages of high automation, good packaging quality, high packaging efficiency and low cost, which improves the economic benefit of packaging industry.
