摘　　要：为了探讨禽蛋大小头自动定向排列关键技术的设计计算方法，对禽蛋在输送辊上的翻转运动进行了机理研究，并进行了不同输送辊直径、输送辊间中心距、不同品种禽蛋的试验验证。研究表明，禽蛋在输送辊上的翻转运动符合凸轮传动原理，构建了禽蛋与输送辊和导向杆之间的传动关系模型，建立了禽蛋翻滚距离和导向杆作用距离的理论计算方法，以及处理通道宽度和导向杆弯曲段长度的设计计算方法，禽蛋翻滚距离和导向杆作用距离理论计算结果与试验值吻合，禽蛋翻滚距离和导向杆作用距离与输送辊中心距呈线性负相关关系，与输送辊直径呈线性正相关关系，决定系数都大于0．94。用凸轮传动原理分析禽蛋在输送辊上的翻转运动是正确的、可行的。In order to develop the design method of automatic orientation of eggs according to the pointed end and the blunt end, the mechanism of turnover motion of eggs on the convey rollers was analyzed and verified under the conditions of different verities of eggs and different diameter, center distance of convey rollers. Results show that the turnover motion of eggs on convey rollers was accordance with the principle of the cam. The transmission model of the egg, convey rollers and guide rod was built; and theoretical calculation method of the roiling distance of egg and the action distance of guide rod were developed. The design and calculation methods of the processing aisle width and bending length of guide rod were also proposed. The results of theoretical calculation were consistent with the test results. The roiling distance of egg and the action distance of guide rod had a positive liner correlation with the center distance of convey rollers and had a positive liner correlation with the diameter of convey rollers. The determination coefficients were all above 0.94. It is feasible and correct to use principle of the cam to analysis the mechanism of turnover motion of eggs on convey rollers.
