ABSTRACT
Filling is a task carried out by machine that packages
cold drinks and water. It also includes volume
selection menu through which user can input the
desired volume to be filled in bottle.
The filling operation is carried out by Programmable
Logic Controller (PLC). Because PLC is cost
effective, very flexible, reduce complexity, space
efficient. By programming PLC we can control entire
system

the world economy. One of the important applications
of automation is in the soft drink and other beverage
industries, where a particular liquid has to be filled
continuously. For these kinds of applications. The
trend is moving away from the individual device or
machine toward continuous automation solutions.

into consistent practice. Totally Int
Automation covers the complete production line, from
receipt of goods, the production process, filling and
packaging, to shipment of goods.
Every system or machine has a controller. Depending
on the technology used, the controllers can be divided
into pneumatic, hydraulic and electronic controllers.

Figure 1: internal architecture of PLC
A. Central Processing Unit :
At the very basic, the internal architecture of a PLC
consists of a central processing unit (CPU) containing
the system microprocessor, memory and input/output
circuitry. The CPU is supplied with a clock which
determines the operating speed of the PLC and
provides the timing and synchronization for all
elements in the system.
The information within the PLC is carried by means
of digital signals which flow along internal paths
called buses.
B. Memory system :
This is the area in the PLC where all of the sequences
of instructions, or programs, are stored and executed
by the processor to provide the desired control of field
devices [7]. The memory sections that contain the
control programs can be reprogrammed to adapt to
any changes in process control requirements.
C. I/O Interfaces :
An I/O module is a plug-in–type assembly containing
circuitry that communicates between a PLC and field
devices. These devices could be transmitting and/or
accepting digital or analog signals.
D. The power supply :
The system power supply provides internal DC
voltages to the system components (processor,
memory, and input/output interfaces).The power
supply is characterized by a maximum amount of
current that it can provide at a given voltage level,
depending on the type of power supply.
E. Programming languages :
Graphical languages:
i. Ladder diagrams (LD) - uses a standardized
set of ladder programming symbols to
implement control functions.
ii. Function Block Diagram (FBD) - a graphical
language that allows the user to program
elements in such a way that they appear to be
wired together like electrical circuits.
iii. Sequential Functional Chart (SFC) - a
graphical language that provides a
diagrammatic representation of control
sequences in a program.
Text-based languages:
i. Instruction list (IL) - a low-level language
similar to the machine or assembly language
used with microprocessors.
ii. Structured text (ST) - a high-level language
that allows structured programming, meaning
that many complex tasks can be broken down
into smaller ones.
IV. PROXIMITY SENSOR
Proximity sensors detect the presence or absence of
objects using electromagnetic fields, light, and sound.
There are many types, each suited to specific
applications and environments.
Inductive sensors
These non-contact proximity sensors detect ferrous
targets, ideally mild steel thicker than one millimeter.
They consist of four major components: a ferrite
core with coils, an oscillator, a Schmitt trigger, and
an output amplifier. The oscillator creates a
symmetrical, oscillating magnetic field that radiates
from the ferrite core and coil array at the sensing face.
When a ferrous target enters this magnetic field, small
independent electrical currents called eddy currents
are induced on the metal’s surface. This changes the
reluctance (natural frequency) of the magnetic circuit,
which in turn reduces the oscillation amplitude. As
more metal enters the sensing field the oscillation
amplitude shrinks, and eventually collapses. (This is
the “Eddy Current Killed Oscillator” or ECKO
principle.) The Schmitt trigger responds to these

amplitude changes, and adjusts sensor output. When
the target finally moves from the sensor’s range, the
circuit begins to oscillate again, and the Schmitt
trigger returns the sensor to its previous output.

sensor
V. WORKING PRINCIPLE
At the input side the bottles are kept in position over
the conveyor. The inductive proximity sensor is used
to detect bottles without making contact. These non-
contact proximity sensor detect ferrous material,
ideally mild steel thicker than one millimeter. The
output is then read by external control unit (e.g. PLC)
that converts sensor ON and OFF state into useable
information. The block diagram is shown in figure 2.
Once the bottle is being detected the conveyor has to
stop till the time is programmed. On the other hand,
the output of the PLC enables solenoid valve in order
to fill the bottle with user defined volume. This
control valve is open when the bottle is detected for a
time specified.
Figure 2: Block diagram
The water is pumped from reservoir tank to overhead
tank and float sensors are used to detect low and high
level of water of the overhead tank. The experimental
setup is as shown in figure 4.

VI. RESULT
The device can fill up to 2 or more bottles of
maximum height of 6.6’’ and maximum bottle
diameter of 4.6” in 1 minute. There is no need of any
external pumps and only two types of sensors are
used. It is a time based control by which the solenoid
valve is open for a time specific and filling process is
done. It can be used commercially in various coffee
shops, juice shops; cold drink shops and reduce
human effort. So the practical research result is much
satisfactory. It also helps to understand the necessity
of PLC in industrial automation and also to realize the
necessity of studying it.

VII. CONCLUSION
We built a PLC controlled automatic bottle filling
system. PLC based automated liquid filling and
control system is a part of industrial production
system. This system is suitable for liquid production
where we need certain amount of liquid. The
automated liquid filling process is operated in such a
way that it saves both time and cost.
