  2. 2. INTRODUCTION ● Vending machine is a machine that dispenses merchandise after customer deposits money. It provides various snacks, beverages, cigarette and other products to consumers. ● The idea is to vend products without a cashier. Items sold via vending machine. ● The first vending machine is believed to have been invented by Hero of Alexandria, a first- century inventor. ● Most vending machines are designed as large safes. ● Most of vending machines are see-through or glass-front merchandisers. This is because it can show clearly and customer able to browse. ● Usually vending machines use a spiral kind of mechanism to separate and to hold the products. ● When the machine vends, the spiral turns, thus pushing the product forward and falling down to be vended.
  3. 3. This project will design and implement a coin operated vending machine controller The Project Involved: ● Design of vending machine ● PLC programming ● Concept of digital logic
  4. 4. Vending Machine Features ➢ Vend 5 products ➢ Accept 3 kinds of coins(50c , $1 , $2) ➢ One coin can be entered at one time ➢ Self-starting with the initial coin ➢ First insert coins, then choose one product at a time!! (cannot vend more than one product at a time)
  5. 5. Design Specifications Inputs Accept 3 kinds of coins(50c , $1 , $2) Output Selected drink Buttons 1 button for turn on/off programme (main switch) 3 buttons for coin input 5 buttons for select product 1 button for reset program or cancel process Equipment used 5 motors 2 LED 2 resistor 330ohm
  6. 6. START END WAIT FOR COIN SPRITEL&PFANTA COKE ZERO COKE IF TOTAL = $2 SELECT DRINK RESET/CANCEL ● DISPENSE DRINK FLOW CHART
  7. 7. Summary ➢ This project proposal telling that the component that might be used. ➢ Our target is to gain knowledge about the basics of how a vending machine works using Programmable Logic Controller. ➢ The flowchart show the flow of process that happen when the user try to buy the product. ➢ vending machine respond to the user’s decision on deciding which product he/she want. ➢ As they press the switch, the can will drop to the outlet corner to let the user get it.
