Critical Time ‘“Motion and Economic Analysis of Linear and Rotary Gravity Conveyor for application One man multi-machine setup as low cost automation in material handling IJTSRD
The rapid growth of technology in the last two decades has been characterized by full automation. As only the affluent and developed countries can afford to adopt full automation, a large productivity gap has been created. This gap can be bridged through low cost automation. The concept and principles of low cost automation are basically the same as those of full automation except that the former builds improvement around existing equipment and machine system rather than replacing whole system with automated processes. Material handling is the primary activity of every manufacturing organization. It has been estimated that at least 15 to 25% of the cost of the product is attributable to material handling activities. Unlike many other operations, material handling adds to the cost of the product and not to its value. It is therefore important first to eliminate or at least minimize the need for material handling and second to minimize the cost of handling. Karakuri mechanisms use a single force or motion to simultaneously perform multiple operations, and also lead directly to energy conservation and resource (facilities) savings. Conventionally gravity conveyors are used to perform material handling task but they are more often of fixed layout type with a singular application. The proposed linear gravity conveyor for flexible manufacture system uses the principle of Converting the force from a dropped weight into gear rotation to activate a conveyor thereby saving the cost of motor and electricity. Conveyors are ordinarily activated by using drive from a motor. In this example, when the conveyor is lifted with a cylinder, a weight drops from the top portion of the conveyor. The force of dropped weight rotates gears that provide movement needed for slide delivery of work (semi-finished products). This mechanism eliminates the need for a motor and enabled a reduction in standby electricity and electricity for operation. Slide delivery requires only the necessary amount of driving energy at the time when needed and is therefore consistent with the concept of ‘œjust-in-time’ electricity. Objective of project is carry out critical analysis as to time-motion and economics of the developed conveyor system with linear and rotary conveyor to determine the i)Transfer time ii)Maximum load carrying capacity .Comparative analysis of the performance of the developed system with conventional conveyor to derive: Change in job transfer time.
