Commodity feeding device and method for vending machine

Abstract

A commodity feeding device and method for a vending machine belong to the field of vending machine. The device comprises a controller (101), a register (102), a row driver (103), a column driver (104) and a motor array (105), wherein the input terminal of the register (102) is connected with the output terminal of the controller (101); the output terminal of the register (102) is respectively connected with corresponding drive lines of the motor array (105) through the row driver (103) and the column driver (104). The method comprises the following steps: firstly running the motor for one week, stopping the flow if the vending detection function is not started, or else, detecting whether a commodity is fed; if so, achieving successful commodity feeding, or else additionally running the motor once; stopping the flow if the commodity is fed, or else, additionally running the motor once; and stopping the flow if the commodity is fed, or else, considering that the commodity is vended out. The commodity feeding device solves the problems of complex connection and poor accuracy and reliability of the commodity feeding device of vending machine.

Description

technical field [0001] The invention relates to the field of automatic vending machines, in particular to a commodity conveying device and method for automatic vending machines. Background technique [0002] In the prior art, the transportation of goods in the vending machine is mainly completed by the mechanical device driven by the electric motor. In most cases, the commodity conveying device of the vending machine is composed of several cargo lanes, and a spiral-shaped shelf driven by a motor is installed on each cargo lane, and the commodities are placed in the intervals of the spiral-shaped shelves in turn. When a customer purchases a product, the corresponding motor rotates for one revolution, and the selected product is pushed forward by one pitch, and the frontmost product is pushed down to the delivery port and handed over to the customer. [0003] In the prior art, in order to measure the number of revolutions of the motor, a coaxial cam is generally installed on ...
