3. INTRODUCTION
• Automation is used to increase production rate with decrease in labor cost, reduction in lead time and
reduction in labor cost
• Conveyor belts are mostly used to automate a assembly line, transporting material from one point to another
• A conveyer belt is basically a linear belt usually made up of rubber or plastic compounds (of high strength)
combined with one or more layers of fabrics such as nylon, polyester, neoprene, or nitrile
• Geneva mechanism can be used to convert the continuous movement of conveyor belt to intermittent motion
• This enables the optimum efficiency of entire assembly line and provide maximize output.
• A simple Geneva mechanism consists of a drive wheel (connected to motor) and a driven wheel (connected
to belt pulleys).

4. PROBLEM STATEMENT
Using conventional conveyor belt with continuous movement throughout operation, factory
operators could not focus on work which leads to lower productivity and increased hazard. The said
problem can be solved by electronic manipulation but it comes with high cost of development,
increased risk of failure and high maintenance.
The main problem here is to find a way to convert the continuous movement to intermittent motion
so that conveyor stops for a particular interval of time (station time) at the workstation and moves
forward so that the worker gets ample amount of time to operate on the workpiece without moving
from the station.

5. OBJECTIVE
To design and fabricate conveyor belt system using Geneva mechanism to implement the following
benefits:
i) To increase production rate
ii)To reduce work in process
iii)To minimize distance moved by worked between operations
iv)To achieve specialization in operation
v) To reduce noise of the conveyor
vi)To save time

6. LITERATURE REVIEW
• P. Kali Sindhur, G. Sri Harsha (2015) proposed to design a mechanism for cutting by giving
intermittent feed. This intermittent feed is given by continuous revolving of circular disk in
Geneva mechanism.
• David B Donner (2014) studied about kinematic study of a mechanism incorporating a Geneva
wheel and a gear train to achieve intermittent motion
• Han Jiayang Yu Kang (2015) wrote that for both inner and outer Geneva mechanism, the
kinematics coefficient of the Geneva mechanism is stable if the groove number of the Geneva
wheel is a constant.
• Ji Shun Song et at. (2013) describes the different types of Geneva mechanisms; external
Geneva mechanism, internal Geneva mechanism and spherical Geneva mechanism.

7. COMPONENTS
• Frame / Stand
• Geneva mechanism
• Flat Belt
• Crowned Pulley
• 5V DC Motor.
Driven Wheel
Driving Wheel

8. WORKING & METHODOLOGY
A continuous rotary motion is converted into the intermittent rotary motion. The 5V DC Motor is
connected with the Geneva drive wheel. The voltage of the motor is being monitored and supplied
by the benchtop DC power supply. The Geneva drive wheel consists of a pin and the Geneva driven
wheel consisting of 4 slots. When Voltage is applied to the motor, it rotates, making the drive
wheel rotate as well. When the pin of drive wheel inserts in a slot of the driven wheel, it causes the
latter to rotate. The Geneva driven wheel is coupled to a crowned flat belt pulley. When the driven
wheel rotates, this pulley also rotates and as the pulley at the other end of the belt is free to rotate as
well, motion is induced in the belt. Hence, an object placed on the belt can now be transferred from
one position to the other.

9. FUTURE WORK
• Compulsory work:
i. Calculations for length of belt, driven wheel radius, centre distance between driver and
Geneva wheel, Geneva driven wheel radius, Slot length on Geneva wheel, Slot width, stop
arc radius, Stop disk radius, etc,
ii. Detailed CAD model of the project
iii. Fabrication of working model
• Possible modification:
i. Implementation of Arduino module or a regulator (rheostat) to vary the speed of motor
ii. Implementation of inverting amplifier (Av=1) to change the direction of motor power

10. CONCLUSION
Components were designed and modelled by us in Solidworks. Due to the aforementioned
benefits of Geneva Mechanism Conveyor Belt, this project can be applied to a larger scale in
industries, especially in production lines, where significant amount of labour is used for the
material handling purpose. Using this mechanism can cut down the cost of additional labour and
also reduce the working time as fewer workers can complete the operation more efficiently. The
primary goal of transporting the materials at regular interval of time will also be achieved.
