INTRODUCTION

Automatic shoe polishing machine is machine which is operated by the infrared system. In this we have to insert our shoe after inserting the shoe in it, the sensors in it get activated and the soft brush present in it starts rotating automatically and removes the dust from the shoe. Then press the shoe towards the nozzle which contains the cream polish, it is dispense through the nozzles. It is present under the black and brown brush. This all process is completed in just 30 seconds and your shoes are well polished. The shoe polishing machines are available in two types: First is executive deluxe which is fully automatic with the electronic timer. And the second one is Esteem which is semi-automatic with the electronic timer. Shoe polishing machine can be operated manually, in which machine remain on as long as switch is ON. By this we can shine our shoes any time or anywhere.They are very light and easy to carry in the pocket and it contains natural cream polish. With the help of this shoe polishing machine people’s get rid of getting hands dirty or black due to polish. This shoe polishing is time consuming job which can be easily solved by using auto shoe polishing machine.

Features of Shoe Polishing Machine • It has dual speed to polish the shoes • It cleans and polishes the shoes in few minutes. • They are compact and completely portable • These machines are suitable to use in the hotels.

WORKING PRINCIPLES

• DC Motor : It is electric DC motor of 12V. DC motors are the part of electric motors using DC power as energy source. These devices transform electrical energy into mechanical energy. The basic principle of dc motor is same as electric motor in general, the magnetic interactions between the rotor and the stator that will generate the spin. DC motors are widely used in speed and direction control because control of these motors are easier than other motors. The motion of a C motors is controlled using a DC drive. DC drive changes the speed and direction of the motion of the motor. It is used to drive gearbox. There are 2 motors used.

fig(1)

• Arduino UNO : The Arduino UNO is an open-source microcontroller board based on the Microchip ATmega328P microcontroller and developed by Arduino.cc. The board is equipped with sets of digital and analog input/output (I/O) pins that may be interfaced to various expansion boards (shields) and other circuits.The board has 14 Digital pins, 6 Analog pins, and programmable with the Arduino IDE (Integrated Development Environment) via a type B USB cable.It can be powered by a USB cable or by an external 9 volt battery, though it accepts voltages between 7 and 20 volts. It is also similar to the Arduino Nano and Leonardo

fig(2)

• L298N Motor driver: The L298N is an integrated monolithic circuit in a 15- lead Multiwatt and PowerSO20 packages. It is a high voltage , high current dual full-bridge driver de-signed to accept standard TTL logic level sand drive inductive loads such as relays, solenoids, DC and stepping motors. Two enable inputs are provided to enable or disable the device independently of the in-put signals .The emitters of the lower transistors of each bridge are connected together rand the corresponding external terminal can be used for the connection of an external sensing resistor. An additional Supply input is provided so that the logic works at a lower voltage.

fig(3)

• Servo motor: A servomotor is a rotary actuator or linear actuator that allows for precise control of angular or linear position, velocity and acceleration.It consists of a suitable motor coupled to a sensor for position feedback. It also requires a relatively sophisticated controller, often a dedicated module designed specifically for use with servomotors.

fig(4)

*Bearing : It is a part of machine that allows one part rotate over another or move in contact with another part it has little friction as possible. Ball bearings are used.

fig(5)

• Jumper wires: A jump wire (also known as jumper wire, or jumper) is an electrical wire, or group of them in a cable, with a connector or pin at each end (or sometimes without them – simply "tinned"), which is normally used to interconnect the components of a breadboard or other prototype or test circuit, internally or with other equipment or components, without soldering.

fig(6)

• Stepper motors are inexpensive and rugged because they have fewer mechanical parts. They are brushless, easy to position, and are commonly used in automation systems, although they are small low power devices as compared to other motors... They move in steps based on pulses sent to the stator windings, thus they do not have a horsepower rating because they do not actually rotate continuously. The speed of the motor is controlled by the frequency of the pulses. The stepper motor is used for precise positioning with a motor, such as hard disk drives, robotics, antennas, telescopes, and some toys. Stepper motors cannot run at high speeds, but have a high holding torque. A stepper motor can be thought of as a "digital" version of electric motor, because it converts digital pulses into fixed steps such that a computer system can easily "step" the rotation of the motor for precise control. A stepper motor is low cost, has simple drive electronics, is accurate, has a decent holding torque, and operates at moderate speeds. High acceleration and heavy loads that still require accuracy need a servo motor, the predecessor of the stepper motor.
