Car wash product vending machines

Car wash product vending machines dispense products for the cars. These vending machines are found in carwashes, oil changing locations, petrol stations, etc. They are very comfortable, convenient and time saving machines. These vending machines offer everything from car air fresheners to visor CD holders. Since many of these locations experience heavy traffic, having vending machines offering these products increases profit while requiring little manpower. Working steps of these machines are similar to that of simple snack machines. Put the coin, select the product and fetch the product if available. If the product is not sensed by the device, the system waits for a second and rotates the helix until the product is sensed as dropped. If a product is still not sensed after a full rotation of the helix to the home position, the selection will be considered empty or sold out and the customer's credit will be restored, which in turn triggers the display message indicating that product is not available. These machines have special features such as bright LED display, high security lock, easy to change coils for different size products, built-in fan for Air Circulation, etc.
