If you want to sell items with different packages, you need to use different storage cabinets, which is time-consuming and labor-intensive, and the cost is high. After years of development, although the existing equipment has been improved, it still cannot perfectly solve the problem of selling multiple types of goods, and , Fluid and liquid goods cannot be sold; (2) The existing vending equipment has a single control form, and the storage temperature and humidity of the goods in the equipment cannot be guaranteed in different environments. It is not conducive to the long-term storage of goods, and cannot completely solve the control problem of the same device under different conditions; (3) Traditional devices are operated by keyboards, requiring users to carry small amounts of cash for payment, poor human-computer interaction experience, and security risks. There are also vending machines. Bank card payment, but there is still the problem of a single payment method; (4) The vending machines currently in use use regular replenishment and regular maintenance methods, and it is impossible to know the operating status of the vending machine and the storage of goods in the vending machine in real time. Provide timely replenishment and timely maintenance services; (5) Existing vending machines do not have a cargo control and management system, and there are problems such as expiration and deterioration of the sold goods.

The goods enter one end of the conveyor belt 506 from the inlet 502, and the conveyor motor 508 starts to rotate, and the commodity moves towards the middle position from one end on the conveyor belt 506. When the diffuse reflection photoelectric switch 508 senses the commodity, the conveyor motor 508 stops rotating; The cargo door motor 516 starts to rotate, and the cargo safety door 515 begins to walk from the left to the right. After the safety door proximity switch 518 senses that it coincides with the cargo safety door 155, the cargo door motor 516 stops rotating; Lift the synchronous belt 510 with the conveyor belt 506 to send the commodity from bottom to top, when the upper proximity switch 513 senses the synchronous belt pressure plate 507, the lifting motor 512 stops rotating; when the commodity is taken away from the conveyor belt 506, Picking up safety door 515 begins to rotate, and picking up safety door 515 begins to move from right to left, and when far-end safety door proximity switch 518 sensed and picking up safety door 515, taking goods door motor 516 stops rotating; Reverse, by lifting the synchronous belt 510 with the conveyor belt 506 to move from top to bottom, when the lower proximity switch 511 senses the synchronous belt pressing plate 507, the hoisting motor 512 stops rotating. After a working trip is over, the subsequent product delivery process will start again and again. The lifting mechanism of the self-service vending machine of the present invention can dock the goods from the outside, and transport the goods from the low place to the high place, which is suitable for people to pick up the goods at a height without bending over, and the process is fast and accurate. When transporting goods, it can protect the safety of users, and there is no problem of pinching hands and hurting people.
