Description

Automatic vending machine for bagged food

Technical Field

The invention relates to the field of vending machine equipment, in particular to a bagged food vending machine.

Background

Along with the progress of science and technology, automatic vending equipment is also more and more, for example in bags food vending machine gives people and buys food and has brought the convenience, has still saved the cost that personnel sold for the operator, has improved operator's economic benefits. The conventional automatic vending machine for bagged food (actually selling not only one bagged food but also other food) generally comprises a shell, an electric push rod mechanism, a main control circuit board, a commodity purchasing operation interface and other necessary supporting equipment, wherein the commodity purchasing operation interface is positioned at the front end of the shell, and a two-dimensional code is also arranged at the front end of the shell; a plurality of goods grids are longitudinally distributed in the shell to place commodities including bagged food and the like (a set of electric push rod mechanism is longitudinally arranged at the rear end in each goods grid). The electric push rod mechanism comprises a motor speed reducing mechanism and a spiral push ring with a certain length, wherein the spiral push ring is positioned at the front side end of a power output shaft of the motor speed reducing mechanism, and a plurality of bags of bagged food are vertically placed between every two push rods (the push ring is made into a spring shape through a metal rod) of the push ring from front to back. When a purchaser needs to purchase food, the purchaser selects required food and pays the payment (the payment can be carried out by a cash receiving coin mechanism of the vending machine and the payment can also be carried out by scanning codes through a mobile phone) through a commodity purchasing operation interface of the bagged food vending machine, a main control circuit board in the bagged food vending machine outputs power for a certain time to enter two power input ends of a motor speed reducing mechanism of a corresponding one of the goods grids (the output power is adjustable according to the requirement, the main control circuit board is provided with a plurality of power output ends which are respectively connected with the power input ends of the motor speed reducing mechanisms in the goods grids through conducting wires), then the motor speed reducing mechanism drives a push ring to rotate for a certain angle, the spiral push ring pushes one bag of food at the front end of the goods grid out of a goods grid to fall into an article taking port at the lower end of the shell (a second bag of food at the front end of, the purchaser takes out the bagged food and completes the whole purchasing process.

Due to the limited structure of the existing automatic vending machine for bagged food, when a plurality of bags of food are placed in the goods lattices, one bag of food is needed to be placed between every two push rods of the push ring from the inside to the outside of the goods lattices, and certain inconvenience is brought to placement of replenishment personnel due to limited space in the goods lattices; and more importantly, because the pushing ring is positioned at the front end of the motor reducing mechanism (the motor reducing mechanism longitudinally has a certain length and can occupy valuable placing space in the goods grid), the front and back lengths of the goods grid cannot be very long, and the gap is large after every two bags of food are placed between the two push rods, so that the placing space in the goods grid is not effectively utilized (the front and back contact states between the multiple bags of food cannot be realized, and the purpose of effectively utilizing the placing space in the storage grid is achieved). In addition, because a set of electric push rod mechanism needs to be installed at the rear side end of each goods lattice, the number of electric push rod mechanisms is relatively large, the cost is high, the cost of the whole equipment can be increased, and the probability of failure is increased due to the fact that the motor and the reduction gear of each electric push rod mechanism have more rotating parts, so that the effective application of the bagged food vending machine is more or less limited (at present, a mechanism for vending food by a motor chain has the defects of high cost and complex structure, and the problem of small space for placing food and drink is also existed).

Disclosure of Invention
