Description

Automatic vending equipment

Technical Field

The invention relates to the field of automatic vending, in particular to automatic vending equipment.

Background

The vending machine is not limited by time and place, and has the advantages of labor saving and convenient transaction. The general flow of the vending machine is that the control panel receives order information, goods fall into the goods taking platform after the user pays successfully, and the user opens the goods taking door to take out the goods.

The inside storage goods mechanism and the goods way that is equipped with commodity of vending machine or automatic vending equipment, commodity are through storing up goods mechanism release and through goods way back shipment, at present, what the release of commodity adopted in the vending machine is complicated gear drive and/arm push rod transmission, release commodity from the commodity tray, then commodity rolls to get the goods mouth, and realizes automatic vending, and this vending machine's transmission structure is complicated, easily breaks down, and it is troublesome to maintain and repair. In addition, a plurality of commodity storage mechanisms and commodity channels have large volumes, low space utilization rate and easy generation of goods blocking phenomenon in the delivery process. In addition, the storage mechanism in the automatic vending machine has limited space, and for selling the commodities packaged in box bodies, how to better utilize the storage space and a simpler and more convenient discharging mode are one of the problems to be solved by the scheme.

In addition, selling commodity and falling into after dashing storage goods mechanism and emit and get the goods platform and supply the consumer to take, in the common vending machine, get and be equipped with on the goods platform and get the goods door, the consumer need take out commodity through getting the goods door, has following shortcoming like this:

1. if the goods taking door is opened in a push-pull mode, the goods taking door can move freely due to the fact that a certain gap is required to be kept between the goods taking door and the cabinet body, the goods are easy to be clamped in an inward pushing mode, and the space is occupied in an outward pulling mode;

2. the mode of hinging the goods taking movable door at the goods taking position adopts the damper as a reset element, but the damper is easy to age and lose efficacy after long-term use, so that the goods taking opening baffle cannot be opened; for the mode of opening the door inwards and upwards, when the goods are taken, the cabinet door is pushed open by one hand to take out the purchased goods, the mode easily causes clamping injury to hands or arms or scratches in the process of taking the goods, and the sold goods can be scratched by the cabinet door when the cabinet door is closed;

3. the door plate is automatically opened, for example, the cost is higher by matching with a sensor to monitor, the requirement of the sensor on the use environment is strict, the requirement on timeliness is high, and unnecessary troubles are caused by sensing failure or failure;

4. the consumer need often contact the door of getting goods in order to get the commodity of selling, because automatic vending equipment is public equipment, the consumer is when pulling or push away the door of getting goods, easily contacts bacterium or virus etc. of staying on the door of getting goods, easily produces the infection, can't reach contactless getting goods.
