Introduction
Water plays a very important role in most of the process industry as well as other
industry.

Water purification is the process of removing undesirable chemicals,

materials, and biological contaminants from contaminated water. The goal is to produce
water fit for a specific purpose. Mostly water is purified for human consumption
(drinking water) but water purification may also be designed for a variety of other
purposes, including meeting the requirements of medical, pharmacology, chemical and
industrial applications. In general the methods used include physical processes such
as filtration and sedimentation, biological processes such as slow sand filters or activated
sludge, chemical processes such as flocculation and chlorination and the use of
electromagnetic radiation such as ultraviolet light.
In our project the total process is carried out in batches so we decided to use PLC as
the controller. Water to be treated is taken into the source tank and pumped into the
process tank where the water is heated at the specific temperature once the water is
heated then it is cooled to a ambient temperature and it is drained to the filter tank
assembly where the carbon filters are used to purify the treated water. The main motto
behind selection of the project was to come across different fields of instrumentation
engineering such as.
Research and development.
Process Commissioning and Installation.
Automation.
Process maintenance and Troubleshooting.

1.1 Brief Application:

Water purification and bottling system is an important part of the industries which
manufactures the products which have to be packed or fill.
Some of the common applications of system are as follows:Dairy Industries
Cosmetic Industries
Pharmaceutical Industries
Beverage Industries
Distilleries Industries
Food Industry

2.1 Schematic of Water Purification and Bottling System

Figure 2.1: SCHEMATIC OF WATER PURIFICATION AND BOTTLING SYSTEM

2.2 BRIEF DESCRIPTION OF THE PROCESS:

1. Initially the water is poured manually in to the storage tank. When the start button is
pressed water from the storage tank is drained into the process tank.
2. Once the process tank is filled with the water till the higher level which is detected by
the higher level sensor mounted inside the tank then the pump1 is stopped.
3. Then the actual process of purification takes place i.e. water is boiled by turning ON the
heater and the heater remains on until the desired set point is reached.
4. When the desired temperature is reached then the water is allowed to cool, after the
cooling is done and the water temperature drops to the room temperature then the water
is drained into the filter tank by turning ON solenoid valve1.
5. Water from the process tank is drained into the filter tank until the water level inside the
process tank drops below the lower level which is measured by the lower level sensor
mounted inside the process tank.
6. Filter tank consist of two membrane filters which are also called as carbon candle filter
which separates the sediments or sand particles if present.
7. Followed by the process of water purification the purified water is used for the bottle
filling.
8. After the bottle filling, bottle is capped by the Robotic arm which is pneumatically
operated and controlled by PLC.
9. Construction and operation of the Robotic arm
It is consisting of Pneumatic cylinders and a cantilever arrangement. The basic operation
of the pneumatic arm is same as that of the human arm i.e. it can function in three
different axis. Following are the movements of the arm
a) Angle from 45degrees to 180 degrees.
b)Vertical up and down movement.
c) Horizontal Forward and Backward movement.

2.3.1 BRIEF DESCRIPTION OF INPUT DEVICES:

1. START BUTTON AND STOP BUTTON PANEL:

Figure 2.1: Start and Stop Button

We have used to push buttons for the purpose of START & STOP. They are mounted
on control panel. Push button is a simple switch mechanism for controlling some aspect
of a machine or a process. Buttons are typically made out of hard material, usually
plastic or
Metal. The surface is usually flat or shaped to accommodate the human finger or hand,
so as to be easily depressed or pushed. When we push the switch inward the contact is
made or brake

According to the connection made to NO or NC terminals of switch

Green push button as shown in the figure is mounted on the control panel in order to
start the process this button is pressed.
Red push button is the stop button mounted on the control panel in order to stop the
process at any instance of time this button is pressed.

2. Level Sensor

Fig: 2.3: Level Sensor

Figure below shows the float level sensor they are used in the process to measure the
level of the water inside tanks. When the required level is reached then the contact inside
the sensors occurs and it provides signal to the controller to take the respective action.

Thermostat is basically a temperature switch to which a set point is provided at which

the temperature is to be controlled. It is mounted in the process tank to control the
process temperature at the desired value. Once the temperature reaches the sp value it
gives the transition signal to the PLC so that the heater is turned off.

4. Photo senor circuit:

Fig: 2.5: Photo Sensor Circuit

A transmitter is often a light emitting diode (LED) which is built into the pointing end
of the remote control handset. The infrared light pulse represents a binary code that
corresponds to a certain command, such as (power on). The receiver passes the code to a
controller, which decodes it and carries out the command.
The remote control is usually contracted to remote. It is known by many other names as
well,

such

as converter, clicker, the

box, flipper,

hoofer-doofer, the

tuner,

'the

zapper', the changer, or the button. Commonly, remote controls are Consumer
IR devices used to issue commands from a distance to televisions or other consumer
electronics such as stereo systems, DVD players and dimmers. Remote controls for these
devices are usually small wireless handheld objects with an array of buttons for
adjusting various settings such as television channel, track number, and volume. In fact,
for the majority of modern devices with this kind of control, the remote contains all the
function controls while the controlled device itself only has a handful of essential
primary controls. Most of these remotes communicate to their respective devices
via infrared (IR) signals and a few via radio signals.

A relay is the device functioning as a switch on application of an electrical signal.

In response to the current through the coil, known as control signal, the relay closes and
opens its switch contacts. The relays are widely use in industry as control devices.
Following are the important application,
a. Control of high power load circuits.
b. Low voltage control of remote equipment.
c. Isolation of control circuits for load circuits.
d.

Switching of field devices on the process plant

Through the relays are available in many types according to the types of construction or
application yet only the electromagnetic relay has been discussed, since we have used
this in our project. The cost of an electromagnetic relay is low because it is utilized in
many applications. An electromagnetic relay consists of an iron core surrounded by coil
of iron which provides flow of reluctance path for magnetic flux. There are three
contacts in relay, namely normally open (NO), normally closed (NC) and movable
contacts.
4. Solenoid valve:

Fig 2.9: Solenoid Valve

Two valves have been used in our system, which are as follows:
1. Solenoid valve for draining the process tank.
2. Solenoid valve for bottle filling.
12

It is an electromechanical device. A solenoid valve utilize electromagnetic coil to

actuate armature or valve stem in magnetic field to control liquid flow. It is operated by
electrical signal from remote location due to electric power supply in the coil due to
which electromagnetic force is produced, which causes the plunger of the solenoid to be
position in the coil. It accepts the signal from PLC and accordingly operated or blocks
the flow of liquid.
We have used I-VC series, class 2 type, normally closed, 24 VDC operated, and with
port size and orifice diameter 6 mm. as its power requirement is 24VDC, it is easily
connected to PLC and it is compactness make it superior.
5. Conveyor:

Fig 2.10: Conveyor

The conveyor consists of a conveyor belt and motor. The conveyor belt is of rubber type,
so that it can move the 3 filled glass bottles weighting up to 0.5 kg/bottle. The length of
the belt 2000 mm, so that four bottles of base length 40mm can be placed at equal
distance, as per required in our project. The motor is of 30 rpm, 12 VDC operated, 6
kg.cm, having current rating of 0.5 A.

13

2.3.3 DESIGN CONSIDERATION:

When designing a Bottling System we need to consider:
What type of product or liquid we want to fill.
How much quantity we have to fill
Type of bottle and cap which we are going to use
What is the time required to fill 1 bottle
Which controller will be best& effective for the system
What type of sensors you will use for bottling
Where you will position the sensors and system components
What is the power requirement of each device
Which type of technique will be effective for all 3 process
What will be the accuracy of system
Will the system be cost effective

CHAPTER 3
ROBOTIC ARM
3.1 BRIEF DESCRIPTION OF ROBOTIC ARM
3.1.1PNEUMATIC SYSTEM:Pneumatic System:
Pneumatic system mainly classified into 3 components, which are:
1. COMPRESSOR
2. REGULATOR
3. FILTER
COMPRESSOR:
Pneumatic systems employ gas that is compressed under extremely high pressure. The
practical use of pneumatics comes in putting that compressed gas to use, or should I say
the use of the rapid expansion of compressed gas. At its most basic level a pneumatic
system holds compressed gas in a specially designed tank and then we release some of
that gas into an expandable chamber. The expandable part of the chamber has a rod
attached to it so that as it expands the rod moves outward.
REGULATOR:
Regulators are interesting pieces of hardware in that they can hold back 5000 psi of air
and let only a enough air through to bring the rest of the pneumatic system up to your
designed operating pressure. Regulators also generally have a purge valve to allow you
to purge all of the air out of a pressurized tank.
15

FILTER:
A pneumatic filter is a device which removes contaminants from a compressed air
stream. This can be done using a number of different techniques, from using a "media"
type that traps particulates, but allows air to pass through to a venture, to a membrane
that only allows air to pass through.

3.1.2 Component of Pneumatic System:

Fig .3.1: Block Diagram of Component of Pneumatic System

3.1.3 Pneumatically Operated Pick & Place System:

Fig 12: Block Diagram of Pneumatically operated picks & place system
16

Working operation of pneumatically operated robotic arm:

Robotic arm is constructed by using pneumatic cylinder which operates the cantilever to
attain different position i.e. to move in various axis. All the pneumatic cylinders are
double acting thus in order to control the action of the cylinders 5/2 way valve with 2
solenoid are required these 5/2 way valve can be operated manually as well as
electronically as our controller is PROGRAMMABLE LOGIC CONTROLLER we have
used 24 Vdc solenoid on the 5/2 way valve so that there is no need of the extra
peripheral device between PLC and 5/2 way valve.
As the main application of our project is to pick and place so we are utilizing our project
in bottling process where the cap from cap source are picked by our robotic arm and is
placed on the mouth of the bottle.
Pick operation of the Robotic Arm:
Source of the cap is at 90 degrees so the initial position of the arm is at 90 degrees. once
the cap is sensed on the conveyor by the photo sensor according to the logic the up and
down movement of our arm is utilized to pick the cap from the cap source conveyor.
Place operation of the Robotic Arm:
After picking the cap from the conveyor the angular movement of the robotic arm is
utilized i.e. from 90 degrees it goes into 180 degrees where the bottle conveyor is
mounted. once the filled bottle is sensed on the conveyor again the up and down
movement is utilized to place the cap on the mouth of the bottle.
Other then these movements there are one more movement i.e. it can also provide
horizontal forward and backward movement.
All these movements are carried out by the individual double acting cylinder and its
respective 5/2 way valve.

Conclusion:
Thus we conclude that the output of the project depends upon the following
parameters:
1. The level of the water in the source tank must be high enough, as it will affect
the water transfer from the source tank to the process tank.
2. Temperature in the tank must be maintained near to the boiling point and must
not exceed above that as the process tank is made up of glass.
3. Filters in the filter tank must be replaced after every 6-8 months to ensure
proper flow rate of the water.
4. Level of the treated water must be above the sufficient level as it will affect the
water flow for filling the bottles.
5. To fill 90ml of water it takes around 20 seconds thus the production rate of the
bottling plant is 4320 bottles per day.
If all this conditions gets coordinated properly with proper setting,100% accurate
result is ensured .

Annexure A
Bit Instructions:
These instructions operate on a single bit of data. During operation, the controller may
set or reset the bit, based on the logical continuity of ladder rungs. You can address a
bit as many times as your program requires.
Note: Using the same address with multiple output instructions in ladder logic is not
recommended since this may yield non-predictable results.
Examine if Closed (XIC):
Use the XIC instruction in your ladder program to determine if a bit is ON. When the
instruction is executed, if the bit addressed is ON (1), then the instruction is evaluated
as TRUE. When the instruction is executed, if the bit addressed is OFF (0), then the
instruction is evaluated as FALSE.

Examples of devices that turn ON or OFF include:

a push button wired to an input (addressed as I1:0/4)
an output wired to a pilot light (addressed as O0:0/2)
a timer controlling a light (addressed as T4:3/DN)

42

Examine if Open (XIO):

Use an XIO instruction in your ladder program to determine if a bit is Off. When the
instruction is executed, if the bit addressed is off (0), then the instruction is evaluated
as true. When the instruction is executed, if the bit addressed is on (1), then the
instruction is evaluated as false.

Examples of devices that turn on or off include:

motor overload normally closed (N.C.) wired to an input (I1:0/10)
an output wired to a pilot light (addressed as O0:0/4)
a timer controlling a light (addressed as T4:3/DN)

In other makes of PLC the instructions XIC & XIO are also known as a Normally
open (NO) and Normally Closed (NC) contact OR Load contact or Load not contact
respectively. But no matter what this instruction is known as, the operation and even
the symbol, of these instructions remains same.
Output Energize (OTE)
Use an OTE instruction in your ladder program to turn ON

a bit

when rung conditions are evaluated as TRUE. The status of

the

addressed bit will change from 0 to 1. In case the rung

conditions are evaluated as FALSE the output remains OFF (0).
43

An example of a device that turns on or off is an output wired to a pilot light

(addressed as O0:0/4).
Bit instructions are generally used with the following data files:
Output and input data files. These represent external outputs and inputs.
The status data file (file 2).
The bit data file (B3:). These are the internal coils used in your program.
Timer, counter, and control data files (T4:, C5:, and R6:). These instructions
use various control bits.
The integer data file (N7:). Use these addresses (at the bit level) as your
program requires.
Timer Instructions:
Timer instructions are generally used to introduce a delay in the process or to perform
time based operations. These are a direct replica of the Hardware timers, used in
sequential relay circuits. However these timers are much more accurate and provide
much more flexibility than such hardware timers.

Each timer address is made of a 3-word element. Word 0 is the control word, word 1
stores the preset value, and word 2 stores the accumulated value

EN = Timer Enable Bit

TT = Timer Timing Bit
DN = Timer Done Bit

Parameters associated with a Timer

Accumulator Value (ACC):

This is the time elapsed since the timer was last reset. When enabled, the timer
updates this continually.
Preset Value (PRE):
Specifies the value, which the timer must reach before the controller sets the done bit.
When the accumulated value becomes equal to or greater than the preset value, the
done bit is set. You can use this bit to control an output device. Preset and
accumulated values for timers range from 0 to +32,767. If a timer preset or
accumulated value is a negative number, a runtime error occurs.
Time base:
The time base determines the duration of each time base interval. The time base is
selectable as 0.01 (10 ms) second or 1.0 second. Other PLCs also offer time base as
0.1 second.
Timer Accuracy:
Timer accuracy refers to the length of time between the moment a timer instruction is
enabled and the moment the timed interval is complete.
Timing accuracy is 0.01 to +0 seconds, with a program scan of up to 2.5 seconds.
The 1-second timer maintains accuracy with a program scan of up to 1.5 seconds. If
your programs can exceed 1.5 or 2.5 seconds, repeat the timer instruction rung so that
the rung is scanned within these limits.
Note: Timing could be inaccurate if Jump (JMP), Label (LBL), Jump to Subroutine
(JSR), or Subroutine (SBR) instructions skip over the rung containing a timer
instruction while the timer is timing. If the skip duration is within 2.5 seconds, no time
45

will be lost; if the skip duration exceeds 2.5 seconds, an undetectable timing error
occurs. When using subroutines, a timer must be executed at least every 2.5 seconds
to prevent a timing error.
