Goods discharge method of vending machine for goods self-descending by using gravity

The invention discloses a goods discharge method of a vending machine for goods self-descending by using the gravity and relates to the field of automation equipment. The method is characterized by comprising the steps that goods are vertically placed between two vertical positioning rods, self-descending can be conducted through the gravity, and goods discharge is completed through displacement change through a first limit clamping head, a second limit clamping head, a third limit clamping head and a fourth limit clamping head. The goods discharge method of the vending machine for goods self-descending by using the gravity has the advantages that the goods are vertically placed between the two vertical positioning rods, self-descending can be conducted by using the gravity, a large-torquemotor is not needed, and the cost is lowered; the mechanical structure can be simplified, and the reliability is improved; cargo space partition plates cannot be needed, and more space is vacated andused for storing more goods.
