  3. 4. PROJECT OBJECTIVE To measure the dimensions (length and height) of objects that are coming through conveyor belt , sensed by the sensors & placed in allocated areas which is predetermined. There are two primary modes of operation on which the task perform. Automatically or manually
  4. 5. BACKGROUND <ul><li>We have chosen a path to implement our innovative ideas in the form of this project named as OVERHEAD BRIDGE ELECTROMAGNETIC CRANE. The basic concept, which is emerged out from our project is to handling objects over a certain height. </li></ul><ul><li>Overhead cranes are designed to a specific application and location. Our crane contain electromagnet hoist.. </li></ul><ul><li>Even in a production line of many products, electromagnetic lifts are used to lift and move metal objects. </li></ul><ul><li>Electromagnets have special simplicity and many advantages to other lifting tools. They are faster and easier to work with. </li></ul>
  5. 6. Features of project <ul><li>There are various FEATURES of our project. It can offer number of advantages to the user. Our project has some of the most countable features that have mentioned below:- </li></ul><ul><li>  </li></ul><ul><li>Automatic: In automatic transmission object should be placed without human interface. </li></ul><ul><li>  </li></ul><ul><li>Manual Manual operation permits the user to make use of a joystick </li></ul><ul><li>  </li></ul><ul><li>Place objects in its compartments/ </li></ul><ul><li>  </li></ul><ul><li>Electro magnetically pick and drop of objects. </li></ul><ul><li>  </li></ul><ul><li>Weight handles up to 500grams. </li></ul><ul><li>  </li></ul><ul><li>Display length and height of the object o on LCD. </li></ul>

ELECTRONIC PART COMPONENTS <ul><li>MICROCONTROLLER ATMEL AT89C52 </li></ul><ul><li>STEPPER MOTORS </li></ul><ul><li>DC GEAR MOTOR </li></ul><ul><li>ELECTROMAGNET </li></ul><ul><li>VEXTA DRIVER </li></ul><ul><li>LCD </li></ul><ul><li>PHOTOTELECTRIC SENSORS </li></ul><ul><li>JOYSTICK </li></ul><ul><li>CONVEYOR BELT SYSTEM </li></ul><ul><li>LIMIT SWITCHES </li></ul>
  10. 11. Why we used 89c52 <ul><li>CISC architecture….less coding when compared PIC & AVR microcontroller </li></ul><ul><li>89c52 controller are easy to programmable. </li></ul><ul><li>89C52 controller has 8k bytes of flash programmable and erasable read only memory. </li></ul><ul><li>The AT89C52 is a low-power, high-performance CMOS </li></ul><ul><li>89c52 is lower cost than other microcontroller i.e. PIC,AVR etc. </li></ul><ul><li>89c52 is commonly available in market. </li></ul>
  11. 12. VEXTA STEPPER DRIVER <ul><li>Two 5phase stepper drivers are used for driving steppers of trolley and hoist. This driver is interface with microcontroller and stepper motors the clock rate of this drives are controlled by the microcontroller. </li></ul>
  12. 13. STEPPER MOTOR <ul><li>Two hi torque 5 phase stepper motors are used in trolley and bridge movement system. This stepping motors are interfaced with the Microcontroller, when the signal is received the motor starts to work with the help of vexta stepper driver. </li></ul>
  13. 14. DC GEAR MOTOR <ul><li>DC gear motor operates on 12 volts and is controlled by the Microcontroller. Two DC gear motors are present here; one is on conveyor belt system and second is on hoist movement system. The motors are interfaced with the Microcontroller, when the signal is received the motor starts to work. </li></ul>
  14. 15. ELECTROMAGNET <ul><li>Round and Rectangular Flat-Faced Electromagnets are used for lifting objects in manually operated or automated operation. Electromagnet is operating at 15vDC. Flat-Faced magnets should only be used on flat, smooth material where the entire magnet face is in contact. </li></ul>
  15. 16. LCD <ul><li>We use 16*2character display Lcd. </li></ul><ul><li>It will display parameters length & </li></ul><ul><li>height </li></ul>
  16. 17. PHOTOELECTRIC SENSOR <ul><li>A photoelectric sensor is a device used to detect the distance, absence, or presence of an object by using a light transmitter, often infrared, and a photoelectric receiver. The detection way is a scattered reflection type and the maximum detection distance range is 30cm. three photoelectric sensors are used for measurement of object dimension. </li></ul>
  17. 18. Photo coupler <ul><li>PC 817 photo coupler is a device that uses a short optical transmission path to transfer an electronic signal between elements of circuits By keeping them electrically isolated. </li></ul>
  18. 19. LIMIT SWITCH <ul><li>Limit switches can be used to control the motions of machines, for example, to indicate that a motor has reached its full position or that a machine tool is in a position to accept another work piece. </li></ul>
  19. 20. CONVEYOR BELT SYSTEM <ul><li>We use 2ft long and 6inches wide conveyor belt. </li></ul><ul><li>This can be controlled by stepper motor also. </li></ul><ul><li>Laser sensors and receivers are also fitted into the structure of conveyor belt </li></ul>
