为了阐明禽蛋大小头自动定向中轴向运动和翻转运动的机理以及优化处理装置的结构参数和输送运动参数，研制了输送辊上禽蛋轴向运动和翻转运动综合试验台。试验台的支撑辊子直径和材质及表面状况、支撑辊子转速和移动速度、支撑辊子中心距、导向杆弯曲角度和与辊子间的距离等结构和输送运动参数可调，利用高清晰数码相机摄录禽蛋的轴向运动和翻转运动的影像，通过截屏获取禽蛋运动的图像，运用图像处理软件解析禽蛋运动参数和姿态参数。用洋鸡蛋30枚对所研制的试验台进行了验证性试验，结果表明洋鸡蛋的轴向运动水平偏转角和轴向运动位移及翻转运动翻转角的运动规律与在禽蛋大小头定向排列装置上测试结果一致。经长时间运行，试验台运行稳定、操作方便和测试可靠，为输送辊上禽蛋定向运动机理的解析和卵形农产品定向研究提供了试验条件。

In order to clarify the mechanisms of the axial motion and the turnover motion, optimize the structure and conveying parameters of the device of automatic orientation of eggs, a synthesized test platform was developed. The structure and conveying parameters(the diameter, material and surface situation of rollers, the rotate speed and convey speed of rollers, the roller center distance, the guide rod bending angle and the distance between roller and guide rod) could be adjusted. The processes of the axial motion and the turnover motion of eggs were recorded by high definition digital camera. Then, the motion and attitude parameters of eggs were analyzed by imagines processing software. The verification test with thirty eggs showed that the laws of the axial displacement and the deflection angle as well as the turn angle of the turnover motion tested by the synthesized test platform were accordance with that tested by the device of automatic orientation of eggs. During a period of running, the synthesized test platform remained stable, operational convenient and the results of tests were reliable.
