CHAPTER 1
INTRODUCTION
Automated Bottle Filling system’ is a miniature form of automatic bottle filling system
used in the large scale industries such as coca cola,hair oil companies etc.so we have tried to create
an automated bottle filling system without using any microcontrollers or any other type of
programming.The industries, which are having manual process of filling, can be automated using
Automation & Controlling techniques.The bottle filling machine is available in different formats
and specifications and therefore can be selected to suit diverse requirements of packaging and
filling in various industries.
Application of Automation components as per requirement resulted the project of automatically
filling andtransporting.In this plant there are following major operations are performed.
The first one is designing the whole plant as it is in the field and secondly filling of the bottle to the
required level and then transporting it with help of conveyor.The Automation components used in
the plants are conveyor system, sensors, and solenoid operated direction control valves and drain
valves.

7
After the end of a process, the filled bottle is collected and the bottle is now ready to be transported
further for sealing and packing purpose.When we want to fill a bottle without any human effort
‘Automated Bottle Filling system’, is literally a matter of easiness. This project takes a system
design approach to rethinking a piece of automation in a very small scale using simple electronic
components.
We use LDR to sense the change in the intensity of light .The IR sensor is used to sense the
presence of bottle .Also there is a reference voltage which we setted in the comparator .Which we
are mainly used as a switch.
Thus we are going to fill water into the bottle when the sensor detect the presence of the bottle

2.3 MODULE WISE DESCRIPTION
2.3.1 POWER SUPPLY MODULE
The direct line voltage is used to give supply by passing it through a 12 volt stepdown
transformer to reduce the voltage.This voltage signal can be passed through a rectifier for
rectification.Rectifiers have many uses, but are often found serving as components of DC power
supplies and high voltage direct current power transmission systems.
When running from an AC source(220V), a transformer is used to transform the incoming mains
voltage to the correct value required for the power supply electronics circuitry.
The resulting voltage waveform is an alternating current. This must be rectified to enable the
power to be smoothed and regulated for use by electronics circuitry.The smoothing capacitor
circuit is used to enable the rectified DC to be smoothed so that it can be used to power electronics

10
circuits without large levels of voltage variation.A regulator is also used to maintain a constant
voltage level.
fig 2.3.1
2.3.1.1 STEP DOWN TRANSFORMER
A step down transformer has more turns of wire on the primary coil and less turns of wire on
these secondary coil.This makes a smaller induced voltage in the secondary coil.
Compare this with a step up transformer.

11
fig 2.3.1.1
It is called a step down transformer because the output voltage is smaller than the input voltage. If
the secondary coil has half as many turns of wire then the output voltage will be half the input
voltage. See the transformer equation.Decreasing the voltage does not decrease the power.
As the voltage goes down, the current goes up.
2.3.1.2 RECTIFIER
A rectifier is an electrical device that converts alternating current (AC), which periodically
reverses direction, to direct current (DC), which flows in only one direction. The process is known
as rectification. Physically, rectifiers take a number of forms, including vacuum tube diodes,
mercury-arc valves, copper and selenium oxide rectifiers, semiconductor diodes, silicon-controlled
rectifiers and other silicon-based semiconductor switches. Historically, even synchronous
electromechanical switches and motors have been used. Early radio receivers, called crystal radios,
used a "cat's whisker" of fine wire pressing on a crystal of galena (lead sulfide) to serve as a point-
contact rectifier or "crystal detector".

12
fig 2.3.1.2
2.3.1.3 IC VOLTAGE REGULATOR
An integrated circuit or monolithic integrated circuit (also referred to as an IC, a chip, or a
microchip) is a set of electronic circuits on one small plate ("chip") of semiconductor material,
normally silicon. This can be made much smaller than a discrete circuit made from independent
electronic components. ICs can be made very compact, having up to several billion transistors and
other electronic components in an area the size of a fingernail.
fig 2.3.1.3

13
2.3.2 BOTTLE FILLING SYSTEM MODULE
In this unit we have used a LDR placed between the bottle and LED . A comparator is also
used At starting condition there will not be any bottles between LED and LDR, thus the resistance
will be very low .A reference voltage 2.5 is set on comparator and low resistance signal is given to
the other terminal of comparator as input.The comparator will compare the incoming signal and it
will be less than that of the set value, thus we will get 1 as output.When a bottle is placed between
LED and LDR the resistance will low since the bottle is transparent.But when the coloured
solution fills the bottle ,the resistance will increase and it will be compared by the comparator.That
value will higher than the set value,thus we will get 0 as output.
2.3.3 BOTTLE DETECTING UNIT MODULE
An IR sensor is used to detect the presence of bottle.Here the non inverting terminal is fixed
with a reference value .When there is no bottle the resistance will be low ,so that we will get an
output as 1.This output is passed through a NOT gate to get the complement.When bottle is placed
,the resistance will be higher than the set value.Thus we will get an output as 0 which is passed
through NOT gate to get 1 as output.

14
2.3.4 COMPARATOR MODULE
2.3.4.1 AND GATE
The AND gate is a basic digital logic gate that implements logical conjunction - it behaves
according to the truth table to the right. A HIGH output (1) results only if both the inputs to the
AND gate are HIGH . If neither or only one input to the AND gate is HIGH, a LOW output results.
In another sense, the function of AND effectively finds the minimum between two binary digits,
just as the OR function finds the maximum. Therefore, the output is always 0 except when all the
inputs are 1.
fig 2.3.4.1
2.3.4.2 NOT GATE
A NOTgate (also often called Inverter) is a logic gate .. It takes one input signal. In logic, there are
usually two states, 0 and 1. The gate therefore sends 1 as output, if it receives 0 as input.
Alternatively it received 1 as input, and sends 0 as output.
Generally, below 0.5V is 0, and 4–5V is 1.
The inverter can be made of a discrete transistor. with other components, or several inverters may
be packaged in an integrated circuit.

15
fig 2.3.4.2
2.3.5 SWITCHING CIRCUIT MODULE
Transistor is working as a switch by the output given by the AND gate which is placed before
that.When there is no bottle ,we will get 1 as output from LDR circuit and I.R circuit.Since the
output from IR circuit is noted with a NOT gate we will get an output as 0 from the AND gate
which will not allow the transistor to rotate the motor.When bottle is placed ,output from the LDR
circuit will be same,but output from IR circuit will be 0 which will noted with NOT gate to get 1 as
output which will switch on the transistor and hence will rotate the motor.When the bottle fills
with solution,output from LDR will become 0,which will switch off the transistor irrespective of
the action of IR sensor,and hence solution will not be pumped by the motor.
2.3.6 MOTOR AND PUMPING MODULE

16
An electric motor is an electrical machine that converts electrical energy into mechanical energy.
The reverse of this would be the conversion of mechanical energy into electrical energy and is
done by an electric generator.
In normal motoring mode, most electric motors operate through the interaction between an electric
motor's magnetic field and winding currents to generate force within the motor. In certain
applications, such as in the transportation industry with traction motors, electric motors can operate
in both motoring and generating or braking modes to also produce electrical energy from
mechanical energy.

transformer.This supply is used to lit the LED.
Light from LED is received by LDR .IR sensor is also placed beside to LDR.Circuit will be turn
on only after detecting the presence of bottle by IR,and light from LED passes through the bottle to
LDR. First there will not be any bottles ,so resistance will be very low since the intensity is very

18
high.A reference voltage 2.5 is set on comparator and low resistance signal is given to the other
terminal of comparator as input.The comparator will compare the incoming signal and it will be
less than that of the set value, thus we will get 1 as output.Another comparator is used in the IR
circuit.Since there is no bottle at first the resistance will be less than the set value.Thus we will get
an output as 1 which is passing through a NOT gate to get the complement. The outputs coming
from both the comparators are passing through an AND gate,so that we will get 0 as an
output,where the transistor will not work as a switch .And hence the motor will not pump the
water.
When the bottle is placed the resistance will be less since the bottle is transparent in
nature.Thus as discussed earlier we will get an output as 1,ie,there is no change in the previous
condition.As the bottle is placed the IR will detect the bottle and hence resistance will be more
than the reference value.Thus it will produce an output as 0. When this 0 is NOTED with a NOT
gate,the complement of this output ie,1 and the output of IR comparator ,ie 1 ,are passing through
an AND gate,thus we will get an output as 1 ,which will allow the transistor to switch on.As the
transistor is switched on, the motor starts pumping water and it fills the bottle.
As the water fills the bottle,the resistance will increase than the set value and hence it will
produce an output as 0.Since this value is 0 ,the transistor will be switched off irrespective of the
action of IR sensor.Thus the motor will stop pumping the water into the bottle.
transformer.
3.3 COMPARATOR
In electronics, a comparator is a device that compares two voltages or currents and outputs
a digital signal indicating which is larger. It has two analog input terminals and and one binary
digital output .

19
fig 3.3.1
3.4 LDR
It stands for Light Dependent Resistor or Photoresistor, which is a passive electronic
component, basically a resistor which has a resistance that varies depending of the light intensity.
A photoresistor is made of a high resistance semiconductor that absorbs photons and based on the
quantity and frequency of the absorbed photons the semiconductor material give bound electrons

20
enough energy to jump into the conduction band. The resulting free electrons conduct electricity
resulting in lowering resistance of the photoresistor. The number of electrons is dependent of the
photons frequency.
fig 3.4
3.5 TRANSISTOR
A transistor is a semiconductor device used to amplify and switch electronic signals and
electrical power. It is composed of semiconductor material with at least three terminals for
connection to an external circuit. A voltage or current applied to one pair of the transistor's
terminals changes the current through another pair of terminals. Because the controlled (output)
power can be higher than the controlling (input) power, a transistor can amplify a signal.

21
fig 3.5.1
fig 3.5.2
3.6 IR SENSOR
A passive infrared sensor (PIR sensor) is an electronic sensor that measures
infrared (IR) light radiating from objects in its field of view. They are most often used in PIR-
based motion detectors.

22
fig 3.6
3.7 LED
An LED lamp is a light-emitting diode (LED) product that is assembled into a lamp
(or light bulb) for use in lighting fixtures. LED lamps have a lifespan and electrical efficiency that
is several times better than incandescent lamps, and significantly better than most fluorescent
lamps, with some chips able to emit more than 100 lumens per watt.Like incandescent lamps and
unlike most fluorescent lamps (e.g. tubes and compact fluorescent lamps or CFLs), LEDs come to
full brightness without need for a warm-up time; the life of fluorescent lighting is also reduced by

23
frequent switching on and off.[2] The initial cost of LED is usually higher. Degradation of LED dye
and packaging materials reduces light output to some extent over time.
fig.3.7
3.8 RELAY
A relay is an electrically operated switch. Many relays use an electromagnet to mechanically
operate a switch, but other operating principles are also used, such as solid-state relays. Relays are
used where it is necessary to control a circuit by a low-power signal (with complete electrical
isolation between control and controlled circuits), or where several circuits must be controlled by
one signal. The first relays were used in long distance telegraph circuits as amplifiers: they
repeated the signal coming in from one circuit and re-transmitted it on another circuit. Relays were
used extensively in telephone exchanges and early computers to perform logical operations.

3.9 MOTOR
An electric motor is an electrical machine that converts electrical energy into mechanical
energy. The reverse of this would be the conversion of mechanical energy into electrical energy
and is done by an electric generator.

CHAPTER 4
APPLICATION OF AUTOMATED BOTTLE FILLING SYSTEM
The technology has been developing ever since the Stone Age. The ancient man applied
their minds towards the techniques to have comfort and betterment in their life.

26
The same phenomenon is continuing even till today.Always there is tendency and thirsty with
human beings to develop a better technique in any working process to attain or to provide less
fatigue and mental stress and more comfort to
the operators.
The industries, which are having manual process of filling, can be automated using Automation &
Controlling techniques.
Application of Automation components as per requirement resulted the project of automatically
filling and
transporting.In this plant there are following major operations are performed.
The first one is designing the whole plant as it is in the field and secondly filling of the bottle to the
required level and then transporting it with help of conveyor
The Automation components used in the plants are conveyor system, sensors, and solenoid
operated direction control valves and drain valves.
After the end of a process, the filled bottle is collected and the bottle is now ready to be transported
further for sealing and packing purpose.
Filling is a task carried out by a machine that packages liquid products such as cold drinks or
water .Traditional methods of bottle filling involved placing bottles onto a conveyor and filling
only one bottle at a time. This method is time consuming and expensive. Our paper aims at filling
and capping bottles simultaneously. The filling and capping operation takes place in a
synchronized manner. It also includes a user-defined volume selection menu through which the
user can input the desired volume to be filled in the bottles. The entire system is more flexible and
time saving. The filling and capping operations are controlled using a Programmable Logic
Controllers (PLC’S). This is because PLC’s are very flexible, cost effective, space efficient and
reduces complexity. By programming the PLC we control the entire system. SCADA (Supervisory
Control and Data Acquisition) is used to monitor the process.
The field of automation has had a notable impact in a wide range of industries beyond
manufacturing. Automation is the use of control systems and information technologies to reduce
the need for human work in the production of goods and services. In the scope of industrialization,
automation is a step beyond mechanization. Whereas mechanization provides human operators
with machinery to assist them with the muscular requirements of work, automation greatly

27
decreases the need for human sensory and mental requirements as well. Automation plays an
increasingly important role in 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. Totally Integrated Automation puts this
continuity into consistent practice. Totally Integrated Automation covers the complete production
line, from receipt of goods, the production process, filling and packaging, to shipment of goods.
Machines employed for filling of liquids or powders into bottles are called bottle filling
machines. The bottle filling machines are the important machine tools for the packaging process in
various industries like pharmaceutical, chemical, agriculture, food etc. The manual methods of
bottle filling cannot be applied in modern industries with bulk filling requirements as the process
can consume considerable time and may causing spilling or wastage of the products. Consistency
in filling of the bottles can also be yet another issue rising out of the manual bottle filling
processes. Therefore the special devices called bottle filling machines are employed in industrial
packaging processes.
4.1Types of Bottle Filling Machine
The bottle filling machine is available in different formats and specifications and therefore can
be selected to suit diverse requirements of packaging and filling in various industries. Bottle filling
machines are today available for meeting various requirements of filling at the industries. There
are filling machines for round bottle filling, machines for filling square type bottles and machines
available for filling bottles of different shapes and sizes. You can always find a semi or fully
automatic bottle filling machine suitable to your requirements like speed, features and
specifications desired and type of bottles to be filled. All you require to do is find a reliable
machinery supplier to get the most reliable at affordable price.

28
4.2 Reasons for Using an Automatic Bottle Filling Machine
There are various reasons for why automatic bottle filling machines are preferred for industrial
bottle packaging processes.
● An automatic filling machine for bottle filling enables faster processes and therefore helps
in saving lot of time for the users.
● An automatic filling machine is equipped with automatic functionalities and therefore
reduces the labor and production costs in the manufacturing and packaging units.
● Modern filling machines are equipped with latest technology like PLC control which allow
efficient and easy filling processes.
● These are preferred for features like no bottle no filling system and energy saving which
help in saving the energy consumed while reducing product wastage during the process.
● These machines are designed for accurate and consistent filling operations.
Therefore with an automatic filling machine one can ensure speed and easy filling processes to
ensure efficient filling of liquids or powders into bottles without wastage.
CHAPTER 5
RESULT AND ANALYSIS
The project on AUTOMATED BOTTLE FILLING SYSTEM is completed successfully.
The product that the group has developed will help in initial used in the small scale industries to
fill the bottle or any other vessel.. The change in resistance is sensed by the sensor . the bottle will
be filled automatically if it is kept in front of LED.It will stop filling if the bottle is filled to the
desired limit.
We planned to use the load cell as the sensor but the output from load cell has not been
available .Thus we changed the load cell instead of that we used LDR to detect the water level.

29
At first we used 555 timer to adjust the time but due to inconvenience we modified the
circuit without a timer but instead we used gates.
On progression of the project we came over the problem of calculation for the application
of conveyer belt and to rotate the tray where we are keeping the bottles. Due to short time period
we were unable to complete the automation in moving the tray.
Now we have successfully completed the automation in filling the bottle and we should
manually move the bottle.Thus we completed our project on the topic Signal Processing and
Signalling by making a working model of AUTOMATED BOTTLE FILLING SYSTEM
CHAPTER 6
CONCLUSION
This is the project which can reduce the time as well as manpower consumption in medical as
well as in industrial field.Earlier huge machines were used for bottle filling system.The complexity
in the design of this machines was a cumbersome job for engineers as well as labourers.Here we
bring our innovation as a biomedical engineer.We are introducing an Automated Bottle Filling
System in a miniature form with simple design.
The approaching of this automated system can be an asset for society.The main advantage of our
new product is a simple logic is used here .As an engineer and all above as students we could find
different ways to get into the product and it also helped us to clear all the challenges that we had
faced during the completion of this project with our simple logics.
We can ensure that our product will be a great success since it is affordable by everyone, and it
will be a new rise in industries for their large scale productions using our idea.By passing through

30
the different stages of this project we could understand the various aspects of a manufacturing
process.Since our product also involves mechanical and electrical processes we could understand
more about those areas also.
Here we have presented a miniature form of an Automated bottle filling system which can be used
in industries with developed version in future
