Design and Fabrication of Automated Industrial Conveyor Using Double Crank Rocker Mechanism

Abstract

Industries all around the world use conveyors as a mechanism to transport boxes from one place to another. With increasing need of different types of conveyors in industry there is a serious demand of sporadic movement mechanism besides continuous movement. The aim of this study is to design and fabricate an automated conveyor targeting small scale industries based on double crank rocker mechanism without using modular programming. The intermittent motion and time difference between moving packages can be obtained by using mechanical linkages and by varying speed of source motor. This machine helps in transfer of parcels intermittently by use of four bars with a simple arrangement. The four bar mechanism includes four links. One link is fixed and the other links act as crank, follower and connecting rod. The rotational motion of the crank link is transferred to the follower by using connecting rod and is converted to the same rotary motion. This machine requires an electric motor to provide input to the system. The advantage of this mechanism over conventional conveyor belts will allow to introduce alterations in shifting cartons or packages or move the parcel for any other purpose and likewise. While in conventional conveyor belts to achieve such mechanism modular programming or programming control will be needed which will add an extra cost in manufacturing and productions.
