The document discusses using a Geneva mechanism to power a conveyor belt. A Geneva mechanism converts continuous rotational motion into intermittent rotational motion. It uses a rising circular connector that locks into slots on the Geneva wheel to drive it. For a conveyor belt, an external Geneva mechanism is used. This provides jerky or instantaneous changes in acceleration. The mechanism helps control the speed and direction of the conveyor belt while saving energy. Potential future applications of the Geneva mechanism discussed include uses in engines, bottle filling machines, and automated sampling.

The geneva mechanism is a system to
convert continuous circular motion into
fixed step circular motion. Geneva
mechanism requires a rising circular
connector extending above the rotating
disc to lock between slots in the
geneva wheel and drive it.
The mechanism used for conveyer belt
is an external Geneva mechanism. This
mechanism gives out production of
jerks or instantaneous change in
acceleration.
In short the Geneva
mechanism converts continuous
rotatory motion of the drive wheel to
intermittent rotatory motion of the gear.

They are very useful in production, automobile
and electronic industries for mass production.
Thus, the use of Geneva mechanism in
conveyor belt helps in saving excess energy
and control the speed of conveyor belt and
making the production and handling
comfortable.

Geneva mechanism, also called Geneva Stop,
one of the most commonly used devices
for producing intermittent rotary motion,
characterized by alternate periods of motion
and rest with no reversal in direction. It is also
used for indexing (i.e., rotating a shaft through
a prescribed angle).

1892 – Manufacturer and inventor Thomas
Robbins designed a conveyor belt system to
transport coal and ore for Thomas Edison's
Ore-Milling Company. His invention won the
grand prize at the Paris Exposition World Fair
in 1900.
The development of the Geneva Conventions
was closely associated with the Red Cross,
whose founder, Henri Dunant, initiated
international negotiations that produced the
Convention for the Amelioration of the
Wounded in Time of War in 1864.
In October 1863, delegates from 16 countries
along with military medical personnel
traveled to Geneva to discuss the terms of a
wartime humanitarian agreement. This
meeting and its resultant treaty signed by 12
nations became known as the First Geneva
Convention.

1. Geneva mechanism may be the simplest and
least expensive of all intermittent motion
mechanisms.
2. They come in a wide variety of sizes, ranging
from those used in instruments, to those used in
machine tools to index spindle carriers weighing
several tons.
3. They have good motion curves characteristics
compared to ratchets, but exhibit more “jerk” or
instantaneous change in acceleration, than better
(more expensive) cam systems.
4. Geneva maintains excellent control of its load at
all times, since it is provided with locking ring
surfaces.
5. The most important advantage in the
conveyor belt using Geneva mechanism is
that we can control the speed and direction of
the belt by just adjusting the length of the rod
attached to the servo motor being used.
