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.

WHY PLC
 PLC play an important role in automaton, this device
can manage and control entire industry to produce
better and quick output. A PLC is a digital computer
used for automation of industrial processes, like
controlling machinery or factory
 Reduces human effort.
 Get maximum effeciency.

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.
OPERATION OF PLC
 Used for packaging machine.
 Spinning machine.
 Winding machine (tension control).
 Molding injection machine.
APPLICATION OF PLC

 The 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.

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.
