Automatic Paper Cutting Machine Using Geneva Mechanism


Abstract: The main principle of the project is to reduce the human fatigue and time consumption by eliminating the marking time required to cut paper in equal lengths. Our proposed system cuts variable size paper in equal and accurate dimensionsbased on Geneva mechanism. Geneva mechanism converts continuous rotary motion into intermittent rotary motion. We use a shaft which isin association with the rotating handle. This shaft has a connecting rod(string)which is connected to a scissor in order to drive the cutting mechanism for cutting paper. This shaft is connected to a sprocket which is in turn connected by a chain to another sprocket. This sprocket is now connected to a Geneva wheel. This wheel is used to drive paper feed into the cutter mechanism. The paper cutting is achieved by crank and rockermechanism. The cutter will be restored back to its original position by a restoring spring. Here we use Geneva mechanism driven by another connecting rod. This mechanism ensures paper feed of equal length inserted at proper time intervals. System uses a supporting frame that maintains proper coordination between feed and cutting mechanism. It proves to be low cost solution in production and can be used in educational institutes, stationary shops, small scale industries
