ABSTRACT
Vending machines first appeared in Western Europe in the 1950s. At that time, a piece of gum
could be obtained for only a dime in subway stations in the United States. This is a new form of
retail. With the development of today's social situation, people's pace of life is faster and faster, and
the automatic selling machine born in the pursuit of convenience has become more and more
popular. Automatic selling machines greatly facilitate people's life. On the premise of meeting the
needs of daily fast-paced life, they can increase the selling efficiency of products, reduce labor
costs, and adapt to various types of goods.
Firstly, this paper discusses the origin, development and development status of automatic
selling machine at home and abroad, discusses its basic design ideas and work flow in detail,
analyzes its working process in detail, and explains its basic composition, characteristics and
working mechanism in detail. On this basis, the design of the control system software is completed,
and the trapezoidal graphics and configuration interface are designed. Taking a case as an example,
the process is divided into several links, and each link is programmed. The function of PLC in
vending machine is described in detail. The software includes most of the workflow of the vending
machine. The vending machine equipment controlled by s7-1200 PLC can effectively improve its
working performance and make it work stably for a long time. At the same time, the touch screen is
used for operation and monitoring. Finally, through computer simulation and experiments, it is
proved that the scheme proposed in this paper can meet the actual control requirements and achieve
the predetermined goal.
