Design & Fabrication Of Spray Painting ROBOT
|
|
COLLEGE: Jawaharlal Darda Inst. Of Tech. Yavatmal
An industrial robot is general purpose programmable machine possessing certain
characteristics which can used to perform various industrial task. The investigation &
atomization of spray painting is awaking the interest for several reasons, among these
environmental & quality aspect are the most important. Minimizing the quantity of over
spray is one of the key issue.
Spray painting is most useful & common application of robot. The consistency & repeatability
of a robots motion have enabled near perfect quality. The spray painting applications seems
epitomize the proper application of robotics, & relieving the human operator from hazardous
environment. These hazards include noxious fumes in the air, risk of flash fires & noise from
the spray gun nozzle. The environment is also believed to pose carcinogenic risk for workers.
Largely because of these hazards, robots are being used with increasing frequency for spray
coating task.These other benefits include greater uniformity in applying the coating than humans
can accomplish, reducing the use of paint, lower needs for ventilating the work area since
humans are not present during the process & greater productivity.To address the various
issues related to spray painting robot, we have developed a low cost, economic & efficient
working model.

AERIAL
LIFT

COLLEGE: K.L.E'S GOGTE INSTITUTE OF TECH.,
BELGAUM.
RECOGNITION : SECOND PRIZE
This equipment uses mechanical links and hydraulic power to drive the mechanism.
Equipment has a mechanical drive that has the purpose of transferring the
motion and force from input source to an output. The device has two arms
mounted on a mobile trolley, which are raised with the help of hydraulic
cylinders. The tie rods are used to make the platform to move always in
a vertical path.Hence by doing this a person standing on the platform can
be lifted to a maximum height of 15 feet.
The aim of the project is to design and fabricate a hydraulically operated
Ariallift. A low cost lift can serve the purpose in order to decrease the
idle time, minimizes the effort required and facilitates safe working environment.
This unit provides a maximum working height of 15 feet from base of the
device and raised by a person on a platform by himself controlling the hydraulic
joystick valve, which in turn activates the electric pump at the base and
also the corresponding hydraulic cylinders.
The unit when collapsed to a minimum height would be 3 feet from the ground
level.
This equipment provides a safe, efficient method of lifting human being
at heights. This equipment replaces the need for having long ladders, which
has high risk when a person climbs at the top most position of ladder. Safety
valves are provided to prevent the platform from descending if a hose becomes
fractured. Wheels are provided for mobility.

DESIGN AND
FABRICATION OF RECIPROCATING PUMP OPERATED BY SOLAR ENERGY
|

COLLEGE: K.V.G. COLLEGE OF ENGINEERING,
SULLIA
RECOGNITION: APPRECIATION PRIZE
Reciprocating pump using solar power involves the simple mechanism in which
a whipper motor is made to rotate, to drive the pump. In this project, the
motor speed is not directly coupled to drive, but is reduced by about 220
times, such that enough torque is produced to drive the motor. The solar
power from just one panel is enough to run the pump and lift the water.
A moderate high head is obtained with less discharge. Since solar power
is available free of cost, the pump is designed in such a way that it could
run continuously 8hrs. Hence the water collected is sufficient for house
hold purpose, for smaller gardens etc.
If the same principle is used with more than one panel and a high power
motor, high discharge can be obtained with higher head and hence and could
be used for industrial purpose also. Since solar energy is non exhaustible
and easily available, there is a large scope for this project.
WORKING PRINCIPLE : The solar energy absorbed by the solar module is collected
in the battery provided.When the power is transmitted to the motor the motor
rotates the gear box where the speed is reduced by 22 times. Then again
the output speed is reduced by 22 times. Then again the output speed is
reduced by 10 times with the help of a gear pinion mechanism. Now the torque
in the main shaft driving the reciprocating pump is increased considerably
through the main shaft. The torque is transmitted to the crank, which reciprocates
the piston rod in the cylinder. The stroke length of the piston can be varied
by adjusting the crank pin in the slots provided in the crank.Thus the rotary
motion of the main shaft is converted into reciprocating motion of the piston.
During suction stroke the suction ball valve gets opened and water is sucked
into the cylinder. During the delivery stroke the water is pushed through
the delivery ball valve. Thus water is discharged through the delivery pipe.

SEED SOWER

COLLEGE: S. J. P. N. TRUSTS POLYTECHNIC,
NIDASOSHI.
RECOGNITION :APPRECIATION PRIZE
In India one age old method of "sowing of seed" is by Indigenous methods
of drilling and broad land broad casting to pour germination and uneven
stand of crop. Saving of seed has significant impact on the crop production.
Also the methods requires more skilled labour and is also time consuming.
Hence keeping this point in view an attempt has been made to design, fabricate
and test a device which can be used for "seed sowing operation."
In addition to cost consideration the parameters like speed and care of
operation are also given due weightage.
The experiments were conducted on the designed model and the result quite
encouraging. The sowing operation on all samples involved only 30 to 35%
of time by conventional method. The advantage with the present device is
that it can be operated with help of tractor. It is simple in construction,low
expensive and can be easily maintained. The operation carried out on this
machine is proved to be worthy of its costs and meets the requirements of
the farmer.

ANTI- LOCK
BRAKING SYSTEM

COLLEGE: MOTICHAND LENGADE BHARTESH POLYTECHNIC,
BELGAUM
RECOGNITION : APPRECIATION PRIZE
Anti Lock Braking system is a mechanical and electronics based device which
provides skid free and steerability while braking. Usually during emergency
there is a tendency of braking hard, this leads to skiding of the vehicle.
ABS (Anti lock braking system) provides an cutting edge for safety of the
occupants. The electronics system counts the rpm of the wheel and also counts
the linear motion. Both the rpm and linear motion are compared in the compurator
bos and gives signal or pulse to the the solenoid valve to release the brake
pressure. ABS was introduced in 1970 in Germany by Mercedes Benz. This technology
has come to India in 2000.
