Abstract - The main motive of this project is to replace
conventional conveyor systems by fully mechanical highly
efficient and low maintenance system and mainly focused
towards small scale industries to automate the material
handling process. In this project work is done by converting
rotary motion into reciprocating motion by Double crank
mechanism .This work is solely based on link and kinematic
mechanism and with use of motor whose rotary motion is
converted to reciprocating motion. This will surely reduce the
efforts for small scale industries and helps to increase its
productivity.
Key Words: double crank mechanism, motor,
reciprocating motion, conveyor systems
1 INTRODUCTION
The need of moving the manufactured components of any
industrial plant is one of the basic needs that need to be
fulfilled in order to ensure the efficiency of the plant as a
whole. There are various prototypes dedicated solelyforthe
in-plant transport of components or totally manufactured
final products. But the thing which does not comply with
most of the conveyor belt systems is that they are not cost
efficient and does not promote intermittent motion unlessit
is programmed also it requires a large amount of capital
investment and not available at affordable pricesnotablyfor
small scale industries. The remarkable advantage of this
project is that it providesintermittent/sporadic motionwith
time delay. Conventional system is not equipped with this
type of sporadic motion unless they are programmedtostop
at a designated stop which again increases the cost. In
Industry there has been a serious demand for intermittent
movement of packages /products projectrightfromthestart
.The continuous motion is less important than sporadic
motion, hence the main firm of the is to produce a
mechanism that delivers this stop and move motion
using mechanical linkages .The advantages of this system is
that the system has a time delay between moving
packages/products, while in conveyor system such actions
cannot be performed unlesstheprogrammedmoduleisused
to produce intermittent stopping hencethistimedelayhelps
in providing value addition for a product.
2 LITERATURE SURVEY
FOUR BAR MECANISM
The mechanism is composed of rigid bodies which are
connected to form linkages. Four bar mechanism consists of
three moving links, one fixed links and four pin points.
Generally, when the links move in parallel planes then the
assembly is called as planarfour-barlinkages.Thelinkmoves
in concentric spheres when the axes of the hinged joints are
set in an angle where their axes intersect.
INVERSIONS OF FOUR BAR MECHANISM
Inversion ofFour barMechanismThetraditionaldefinitionof
mechanism basically sums up as where there is a link which
is fixed and the other links are moving thenitisamechanism.
In four bar different mechanism can be obtained when we
adjust the intersecting pathsoftheaxesofthelinkages.These
are called as inversions of the mechanism. By changing the
fixed link, the number of mechanisms which can be obtained
is equal to the number of links. Therefore except the original
mechanism, all other mechanisms are inversions of original
mechanism. Functions of linkages Obviously the function of
any link mechanism is to produce rotating, oscillating or
reciprocating motion from the rotationofcrankorviceversa.

Linkage functions are to provide relative motion, Path
generation: path of the tracer point and Motion generation:
motion of coupler link.
DOUBLE CRANK MECHANISM
Double crank mechanism one of the inversions of four bar
chain mechanism is used for the development of this
project,where link 1 is fixed the link 2 and 4 will rotate and
link 3 will oscillate. This inversion having major advantage
that its two of the links will rotate and hence called as
Double crank mechanism.
GRASHOFF’S LAW
Grashoff’s Law state that for a planer four bar linkage, the
sum of the shortest and the longest link length cannot be
greater than sum of the remaining two link length , ifthere is
a continuous relative motion between the members .It is
important to note that in four bar mechanism if none of the
link make a complete revolution then it is not useful in
practical application, hence it is necessary that one of the
link must be revolving link. With the help of Grashoff’s Law,
it can be easily tested that whether any link can make
complete revolution or not.
S + L < P + Q
where:
S = length of shortest bar
L = length of longest bar
P, Q = lengths of intermediate bar
3 MAIN COMPONENTS USED
3.1 Linkages
A mechanical linkage is an assembly of bodies connected to
manage forces and movement. The movement of a body, or
link, is studied using geometry so the link is consideredto be
rigid. The connections between links are modelled as
providing ideal movement, pure rotation or sliding for
example, and are called joints. A linkage modelled as a
network of rigid links and ideal joints is called a kinematic
chain. Linkages may be constructedfromopenchains,closed
chains, or a combination of open and closedchains. Eachlink
in a chain is connected by a joint to one or more other links.
Thus, a kinematic chain can be modelled as a graph in which
the links are paths and the joints are vertices, which iscalled
a linkage graph. The movement of an ideal joint is generally
associated with a subgroup of the group of Euclidean
displacements. The number ofparametersinthesubgroupis
called the degrees of freedom (DOF) of the joint. Mechanical
linkages are usually designed to transform a given input
force and movement into a desired output force and
movement. The ratio of the input speed to the output speed
is known as the speed ratio.
3.2 Dc motor
A DC motor is any of a class of electrical machines that
converts direct current electrical power into mechanical
power. The most common types rely on the forces produced
by magnetic fields. A windscreen wiper or windshield wiper
is a device used to remove rain and debris from a
windscreen or windshield. Almost all motor vehicles,
including trains, watercraft and some aircraft, are equipped
with such wipers, which are usually a legal requirement. A
wiper generally consists of an arm, pivoting at one end and
with a long rubber blade attached to the other. The blade is
swung back and forth over the glass, pushing water from its
surface. The speed is normally adjustable, with several
continuous speeds and often one or more "intermittent"
settings. Most automobiles use two synchronizedradial type
arms, while many commercial vehicles use one or more
pantograph arms.
3.3 DC battery
A battery is a device that can create electricity using a
chemical reaction. It converts energy stored in molecules
inside the battery into electricity. They produce direct
current (DC) electricity (electricity that flows in one
direction, and does not switch back and forth). Using the
electricity from an outlet in a house or building is cheaper
and uses less energy, but a battery can provide electricity in
areas that do not have electric

3.4 Steel Frame
Steel frame is a building techniquewitha "skeletonframe"of
vertical steel columnsandhorizontal I-beams,constructedin
a rectangular grid to support the functioning/motion links
and provides rigidity.
4 DESIGN OF PROJECT WORK
We have used CREO software to design our project, and
the final design is as follows
PROCEDURE
1. First of all we have prepared design for the material
transfer machine
2. We took the iron angles and cut them in to the required
measurements using the cutting machine.
3. Then we took them and welded thosetoproduceframefor
the material transfer system.
4. After making the welding of iron angles the frame for the
machine was ready.
5. Then we have used wood to make links forthemechanism
,we took wooden repars and cutted them into the required
dimensions.
6. After preparing the shaft, hanger and crank wetakeitover
the drill machine to make the holes in them as the given
dimension in the drawing.
7. After this we had prepared the shaft which is going move
the boxes to the next level with using it edges on the topof it.
We cut the mild sheet plate in the given dimensionsandthen
edges also, after cutting we make theweldingtoattachthese
edges with the plate on the given distance dimensions. Then
with the help of file we rub these weldingpointstogivethem
a good look.
8. Now all of the things for the machine are prepared.
9. On this step we took the electric motor and fix that on the
bed of the machine on the given place.
10. After fixing the motor we fixed the crank withitfromone
side and other side was attached to the

6 CONCLUSION
The material handling sy plays a major role
in industries, the process of transporting or
shifting products from one place toanotherwasto
be maintained by conveyors only. So we just
successfully altered this with a box shifting
mechanism using the kinematics links and a
motor. We had just implemented our basic
mechanical knowledge and designing skills for
designing and fabricating thisproject successfully.
Thus this project work might be useful in all
industries. For practical applications this is

fabricated for light duty operation. Its height,
weight and other mechanical designs may be not
suitable for any other heavy operation or work on
hardened material. We are proud that we have
completed the work with the limited time
successfully. The project works with satisfactory
conditions.
