Objective To increase the automaticity of the ceramic tile packing machine, the structure parameters of the filling equipment were optimized. Methods The packaging efficiency was set as the goal, and an objective function of the ceramic tile transportation time t was established based on MATLAB, to realize the optimal design of the conveying distance of ceramic tile. Results According to the optimization result, the conveying distance was obtained (x1=972 mm), and a three-dimensional drawing was achieved. Conclusion The design of filling equipment could meet actual requirements and improve the automaticity. The objective function was also suitable for solving the moving track of equipments among packing machines with requirements of acceleration.
