Introduction:

It is a fully automatic machine entirely controlled with

microcontroller and PLC.

This operation is just like todays world vendor machine.

The output of the process is very hygienic.

Process starts with mashed potato filling inside the pani puri and

ending with water filling into it.

Technologies used :

Conveyer belt control

(a.) A conveyor belt consists of two or more pulleys with a

continuous loop of material ( the conveyor belt) that rotates about them.

(b.) One or both of the pulleys are powered, moving the belt and the

material on the belt forward.

R.F. control

For reading the customers token to start the machine.

P.L.C. control(a.) An hardreal time system.

(b.) A digital computer used for automation of electromechanical

processes.

SCADA control(a.) This generally refers to control system.

(b.) A computer system that controls and monitors the entire

functioning.

AutoCAD

This computer software is used for designing the base of the machine.

Microcontroller- for the display purpose of what customer hasordered.

Database- for keeping the record of the total sell by the machine andthe total amount of the sell.

Description of the model machine:6

Here the pani puri machine is broadly divided into 5 major sub parts:

1. The pani puri inlet point.

2. The holing mechanism use to puncture the pani puri.

3. The check point for the pani puri if it is damaged whilind

puncturing it.

4. The automatic potato filing in the pani puri in fixed quantity.5. Last part is water filling in it according to the customer's

taste/demand.

WORKING:-

Customerhas to

purchase

the tokenaccordingto his wishfrom thecounterthere.

Now,he/shehas to

insert that

token inthemachineat his/herrespectivecounter totake theproduct.

As thetoken is

inserted inthe

machinethe m/c

came toknowwhere thecustomeris and thequantity

thathe/she

wants of

pani puri.

After it them/c startsand the

panipatasha

comes onthemoving

conveyerone by

one andpasses tothe further

level.

Now, ahole

mechanismis there to

create hole

in the panipatashathrough a

gearedmechanismfor filling in

thematerial in

it.

Further itgoes to

the potato

mixturefilling

through apneumaticpressurecylinder.

Now itpasses to

theindividualcustomers

belt and witha time delayit is passed

to thecustomer byfilling it with

the mostimportantand tasty

thing ofpanipurii.e. its

spicy water.

Here thebeauty of

the machineis the that

thecustomerhas theoption toselect the

taste of thewater to befilled in thepani puriforeach of thepiece that

he receivesat the timeof inserting

the token.

PLC Used:-

Allen Bradely Micrologix1100(1763 L16BBB)

Input extension card(1762 IF8)

Output extension card(1762 OW8)


10/16

Components required :

PLC : 1 PLC Micrologix 1100( Allen Bradley)

Sensors : 8 sensors( capacitive/ proximity)

Switches : 3 limit switches (sensors type)

Motors : 6 motors for the conveyer system.

Heavy torque motors : 3 such motors for the lid control,

holing and for filling the mash potato.

Food grade material for conveyer.

Water tanks for storage.

Valves : 10 valves for the water control.

Solenoid valves : 2 solenoid valves for the air pressure control.

Air compressor : 1 such item

SMPS: one in number

Extra extended cards for more input output with Micrologix 1100.

Pneumatic cylinder /vibrators for the mashed potato filling

machine.

12/16

Drawbacks :

Detection in the case of breakage of pani puri.

Water spreading over the entire belt due to waterfilling.

Initial cost of the system is high.

13/16

Advantages :13

Simple and fast mechanism

User friendly control

Hygienic process

Manpower less required.


14/16

Futures Modifications:

This R.F. token can be replaced by directly inserting the cash

into the machine like the vendor machine.

Manufacturing of the pani purican also be made automatic.

Touch screen HMIs can be provided at the customers panel.
