Design & Implementation of Double Head Liquid Filling

Machine

INTRODUCTION Our Project Is About Double Head Liquid

Filling Machine. It also Called Volumetric Filling Machine

Depending on Classical control Theory In Design.

It is Semi-Automatic Volumetric LiquidFilling Machine.

It is widely used for milk filling, oil filling, ointment filling, shampoo filling, juice filling, liquor filling, perfume filling, wine filling, food product filling – in Jar, Can, Vial, Bottle, Tub & any Containers.

OPERATION OF MACHINE 1)Filling hopper with liquid. 2)Connect the machine to supply source (220v 50 HZ

AC). 3)We should make sure that the emergency switch is

off state. 4)Push the push Button switch. 5)Put selector switch on (ON STATE). 6)Calibrate the package with (off delay timer). 7)Put the package on plate, press on plate slowly,

limit switch which is under the plate will be pressed and send pulse to on delay timer which start to count (1,2,3,…) the time we need to adjust the pack under the nozzle correctly .

8)After the on delay timer finished counting it send pulse to off delay timer to start its operation.

9)The off delay timer close its contact and send an operation pulse to solenoid valve to open to fill the package.

THE IMPORTANCE OF EACH COMPONENT IN THE MACHINE:- ►(1) Fuse 3 Amp. : ●Provide over current protection of source

circuit or loads. ●protect from short circuit state. ●protect electrical component from damage. ► (2) emergency switch : ●Ensure safety for persons and machine. ●Provide a consistent, predictable, failsafe

control response. ► (3) Push button( NO) : ●It is a temporary switch used to give

electrical pulse to relay coil to energize the relay coil.

► (4) lamp 220v : ●To show the state of input source and relay coil.  ► 5) relay :   ● Take the pulse from push button then its coil

energized and its auxilary contact (1 3) changes its state (closed) to power the machine. 

► (6) transformer 220/24v : ● Used to step down the volt to 24v in order to be

easy for controlling and converting to DC. ► (7) bridge : ●Used to convert 24 v AC ( The transformer

output to 24v DC to be safe and suitable for electrical component that we used. 

► (8) capacitor :   ●Used to reduce the ripple in the dc wave form.

► 9) fuse 0.5 amp : ●For protection in power supply circuit. ►(10) selector switch one direction : ●To control in opening the number of nozzles

we need (one nozzle or two nozzle). ► (11) on delay timer: ●take the electrical pulse then counting its

duration then changing its contacting state. ●we fixed it outside the panel to be easy for

calibration. ●used for calibration the volume of package

with the duration time that we adjust it. ●used to give the user time to adjust the

package under the nozzle correctly.

► (12) Off delay timer :   ●After taking electrical pulse change its contact

state then counting its duration. ► (13)Solenoid valve : ● It is the path of water from tank to package it

can open or close according to electrical pulse that taken from off delay timer and its auxiliary contact that connect series with solenoid coil.

► (14) limit switch : ●used to give pulse to energize each head coils. ► (15) led 1 : ●show the state of on delay timer. ►(16) led 2 : ●show the state of solenoid valve or off delay

timer stat.

POWER SUPPLY We use a power supply to convert 220 volts AC

to 24 volts DC to prevent us from electrical shocks.

This power supply consistes of: (1)Transformer

(2)Bridge

(3)Capacitor

(4) Fuse (0.5 Ampere) for protection

Why did we use classic control in design ?

● As its component available in everywhere in markets.

● Easy in instruction.● Easy in dealing with it.● Easy in maintenance.● It does’nt need any

programmable language.

MECHANICAL DESIGN

Implementation

SYSTEM COMPONENTS: 1- Tank (hopper) 2- Solenoid valves 3- Limit switches 4- Control panel 5- Power supply 6- Push button 7- Emergency button 8- Selector switches 9- Lamps or led 10- Timers 11- Relay 12- Machine body

Now we will explain in details all these components and how we can use it in our project.

(1) Tank (Hopper): Because of using liquid we should use hopper

made of stainless steel or Galvanized Iron.

The hopper fixed on the machine body and provided with two nozzles as shown in fig

(2) Solenoid valves We used solenoid valves witch not depend on

pressure because the pressure on tank is very small

(3) Limit switches This is the switches that send pulse to control

panel (relays and timers).

This type of plunger easy to fix in machine body as shown in fig

(4) Control panel We used control panel with dimensions

40cm*50cm*20cm.

CONTROL PANEL COMPONENTS

(A) power supply We used power supply to convert from 220v

AC to 24v DC. because we fill liquid to protect us from electrical shock.

(b)Push button.

(C) Emergency button.

(d) Selector switch.

(e) Lamps and leds Used to show us the state of operation of each

component we used one lamp 220v AC in the input and four leds 24v DC in output two leds connecting with each solenoid valve and two leds with each internally timer.

(f) Timers we used two kinds of timer Off delay and ON

delay

(1) Off delay which fixed external the panel as shown in fig

(2) On delay timer witch fixed internal the panel as shown in next fig.

(g) Relay We used electromechanical relay 220v AC as

shown in previous fig.

The completely panel after adding all components.

MACHINE BODY We used machine body from metal provided

with four wheels to make the movement easy.

MACHINE DEVELOPMENT STAGES We can add some component to make our

machine smart for examples: 1) Adding high level and low level sensors (Capacitive

Proximity) on machine tank to adjust liquid level. Liquid is pumped to tank by using motor pump. This motor pump need circuit breaker, contactor and over load (for control and protection).

2) Adding digital counter to count number of package that filled .

3) We can develop the machine by changing the operation mode by providing load cell and its indicator instead of volumetric mode (calibration the volume of package with timer ).

4) We can use conveyer belt with servomotor to make operation faster.

5) We can use microcontroller or PLC instead of classical control.
