Development of Mini Conveyor Using Genva Mechanisms (original) (raw)

The Development of mini conveyor using Genva Mechanisms described in this project is designed primarily to carry one person according to the specifications of the client. The development of mini conveyor using Genva Mechanisms is moved by an battery powered machine that drives hardened steel traction sheave over which the ropes are suspended. It has advantages is one part travel to another side . They used in all conveyor belt . Geneva mechanism is a method to transform continuous circular motion into intermittent/fixed step circular motion i.e. a circular motion produced in equal intervals of time and resulting in the same displacement. The name “Geneva” is derived from Geneva, Switzserland where in its earliest days the device was used in mechanical watch making. The Geneva drive is also called a Maltese cross mechanism due to their visual similarity. 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. It has a basic function of transporting material from one point to another. A simple Geneva mechanism consists of a drive wheel (connected to motor) and a driven wheel (connected to belt pulleys ). The drive wheel is a disk with a pin or a shaft near its circumference. The driven wheel consists of several slots. The drive wheel is kept next to the driven wheel in such a way that when the drive wheel is rotated, the pin or shaft fits inside the slot of driven wheel. As it reaches the inner most point of the slot, the pin exerts a force on the driven wheel. As the driven wheel is pivoted from the center, a moments produced which causes the generation of a torque, leading to the rotation of the driven wheel and the pulley attached to it. Hence, there is an intermittent circular motion in them resulting in the movement of the belt. There are several types of Geneva rotator such as external Geneva rotator, internal Geneva rotator and spherical Geneva rotator. The mechanism that I will be using for the conveyer belt is of an External Geneva rotator in which the rotating drive wheel interacts with the driven wheel externally.
