The invention discloses a vending
machine commodity placing method and device of a spring type commodity channel, and the method comprises the steps: constructing a multi-dimensional commodity feature
database, and the multi-dimensional commodity feature
database comprises the size, weight and suitable placing position parameters of commodities; according to the parameters in the multi-dimensional commodity feature
database, a double-spring commodity channel is divided into two single-spring commodity channels by using a commodity channel
type conversion strategy, or two adjacent single-spring commodity channels are combined into a double-spring commodity channel; after the type of the goods channel is converted, checking the total number of springs to ensure that the sum of the number of used springs and the number of available springs does not exceed the maximum capacity of the springs of the vending
machine, and mapping the occupation state of the springs of the goods channel; and according to the spring
verification result and the goods channel state, goods placement is completed through a scene
racking strategy, and the goods channel state comprises the number of empty single-spring goods channels, the number of empty double-spring goods channels and the number of pairs of adjacent empty single-spring goods channels. According to the invention, the flexibility and the operation efficiency of commodity shelving / unshelving are improved.
