A new automatic vending machine was designed. The principle of the selecting and pushing of vending machine was introduced, and the three dimensional model was established. The software ADAMS was used to carry out dynamic simulation and optimization analysis. The vending machine can transport the goods to outlet rapidly and steadily. When the pushing velocity was kept at the speed of 150 mm/s left and right, the goods have low wiggle and high stability, and it can provide the experimental basics for the practical design. In the case of equal occupancy area, comparing to the height of the market vending machine of drink and wine, this vending machine is about 1/3 high to that on the market. with lower whole volume and higher storage amount, It is not only satisfied with the use of the general population, but also convenient to operate for the short and small crowd.
