Introduction
Paper punching is a routine process used for documentation, file binding, and
archiving across offices, institutions, and businesses.
Traditionally, this task is done manually, which leads to inconsistency, operator
fatigue, and low productivity.
To overcome these limitations, this project proposes a mechanical solution using
the Geneva mechanism — an indexing device that enables precise, repeatable
intermittent motion using continuous input.
This system automates the paper punching process efficiently, ensuring accurate
and consistent hole placement.

Problem Statement
The current manual punching method suffers from multiple challenges:
• Inconsistent hole placement due to human error
• Operator fatigue during large volume processing
• Difficulty in maintaining uniform spacing across sheets
• Reduced productivity and throughput
There is a clear need for a compact, low-cost automated system to carry out repetitive
punching tasks efficiently, accurately, and consistently.

Objectives:
• Design a machine that automates the paper punching process
• Use Geneva mechanism to achieve intermittent motion
• Reduce manual effort while improving consistency and efficiency
• Create a cost-effective and low-maintenance mechanical solution
Scope:
• Suitable for documentation offices, educational institutions, and
administrative sectors
• Designed for A4/A3 paper formats
• Can be extended to automate feeding and ejection in future

Methodology

8. 8
When the switch is ON , the motor rotates the crank wheel.
Hence the punching slide with punching tool moved up and
down and make a punch on the metal sheet. The crank wheel
face have a pin which touches the slot in the Geneva wheel and
also rotates (indexing) the Geneva wheel .Due to the rotation or
indexing of Geneva wheel , the metal sheet feeding rollers are
rotated through the chain drive mechanism and hence the metal
sheet is feeded automatically.

Advantages, Disadvantages, Applications
Advantages:
• High punching accuracy and repeatability
• Minimal electricity consumption
• Low-cost design using basic mechanical components
• Simple, easy-to-maintain mechanism
• Compact and portable setup
• Ideal for batch punching jobs
Disadvantages:
• Speed limitation due to intermittent nature of Geneva mechanism
• Not ideal for thick or multi-sheet punching without redesign
• Manual paper feeding in current model
• Requires consistent maintenance of moving parts

Applications:
• Schools and Colleges for document binding
• Office documentation centers
• Libraries and archives
• Record-keeping and filing departments
• Low-volume printing and packaging industries

13. 13
Conclusion:
The proposed machine successfully automates a traditionally manual operation with
improved precision and productivity.
By implementing a Geneva mechanism, intermittent motion control is effectively
used for mechanical actuation of the punching tool.
The design proves to be reliable, user-friendly, and economical.
Future Scope:
• Incorporate automated paper feeding and ejecting
• Add sensors to detect alignment and jams
• Use microcontroller for digital operation and monitoring
