IMPORTANCE OF AUTOMATION Increases the machine efficiency. Flexibility and convertibility in manufacturing process Increase production rates

WHAT IS PLC? PLC means Programmable Logic Controller. These systems perform many functions, providing a variety of analog and digital input and output interfaces; signal processing; data conversion; and various communication protocols.

PIN DIAGRAM OF PLC

Our plc model is DELTA DVP-60ES2 Our plc model is DELTA DVP-60ES2. It consists of 36 inputs and 24 outputs.All inputs and outputs are in digital (binary format)type. It represent to X0,X1,X2,X3,X4,X5,X6,X7,X8,X9,X10,X11,X12,X13,X14,X15,X16,X17,X20,X21,X22,X23,X24,X25, X26,X27,X30,X31,X32,X33,X34,X35,X36,X37,X40,X41,X42,X43 are inputs. And out puts are Y0,Y1,Y2,Y3,Y4,Y5,Y6,Y7,Y10,Y11,Y12,Y13,Y14,Y15,Y16,Y17,Y20,Y21,Y22,Y23,Y24,Y25,Y26,Y27. C0,C1,C2,C3,C4,C5 are common pins. COM1,COM2,COM3 are communication ports. RUN AND STOP BUTTON to run and stop the PLC.

OPERATION OF PLC The operation of the PLC system is simple. It consists of three processes: 1. Scans or reads, from the input devices. 2. Executes or “solves” the program logic. 3. Writes to the output devices.

APPLICATIONS OF PLC Used for packaging machine. Spinning machine. Winding machine (tension control). Molding injection machine. .

AUTOMATIC WATER FILLING SYSTEM Our project is based upon closed loop control system. A Closed-loop Control System, also known as a feedback control system is a control system which uses the concept of an open loop system as its forward path but has one or more feedback loops (hence its name) or paths between its output and its input. The reference to “feedback”, simply means that some portion of the output is returned “back” to the input to form part of the systems excitation.

EXPERIMENTAL KIT

COMPONENTS USED: DC SERVO MOTORS PHOTO ELECTRIC SENSORS CONVEYOR BELT MOTORS ELETRO MAGNETIC RELAY AC & DC TERMINAL BLOCKS MCB & SMPS  

WORKING   When the start button is pushed, the motor starts hence the conveyer belt starts moving. When the bottle is under the solenoid valve, the bottle is sensed and the motor stops hence the conveyer belt stops. Then the solenoid valve operates and the bottle starts filling the water. When the bottle completes filling process, the solenoid valve is closed and the motor starts, the conveyer belt starts moving and carries the bottle away from the solenoid valve. If another bottle is sensed then the above process will be repeated. When stop button is pressed or activated then the entire process will be stopped.

PROGRAM USED IN THIS PROJECT

INPUTS X0 ------WATER LEVEL SENSOR X1--------PUSH BUTTON X2-----CONVEYOR BELT SENSOR OUTPUTS Y0 ------RESERVOIR MOTOR Y1--------WATER TANK MOTOR Y2 & Y3 -----------CONVEYOR BELT MOTOR M0,M1,M2-----------MEMORY BITS T0,T1-------------TIMERS

MERITS Less man power required. Less time taken. Fast and accurate. Less wiring. Easier and faster to make changes.

APPLICATIONS Stand alone water bottle booth system. Ink filling industry. Soft-drink & water filling industries. Beer and wine industries. Olive oil industries.

CONCLUSION We have achieved our objective that is bottle filling process using PLC. This was successfully implemented. We consider this project as a journey where we acquired knowledge on automation industry. Also gained some insights into the subject which we have shared in this report
