In order to provide AUTOMATION and to reduce themanpower.
This article involves full automation of the conveyorand raw juice tank using Programmable Logic Controller
(PLC).
Here the automation reduces the consumption time
by one-fourth of total process.
Safety is assured.

Programmable Logic Controller (PLC) is the controller
which controls a system by means of its given input
program.
This program is given by the user.
The Program can be changed according to the
requirement or process.
Extension modules are available, for large process.

The primary reason for including the plc is to
eliminate large cost involved in replacing the
complicated relay based machine control system.
Easy understandable programming language.
Easy of programming and reprogramming in plant
High speed and it reduces time consumption.5

The float gives the continuous signal to the PLC
PLC compares this with setpoint.
When it exceeds, then Solenoid valve will be closed.
This also stops the conveyor motor.

Load cell is connected along with conveyor.
This gives the amount of load passing through the
conveyor.
This is send to PLC for control.
PLC checks this value with setpoint.
When this exceeds, then conveyor motor is stopped.
