Abstract
In the jacquard weaving system, more than 10 000 cards having multiple holes thereon in a particular way are required to produce a pattern on woven cloth. To make these kinds of selective hole, which are based on the type of pattern, is cumbersome and time consuming. In order to solve this problem, in this paper, a locking mechanism is presented on the basis of which a multi-punching system is designed to create selective holes. Fundamentally, a locking mechanism is used to lock or unlock a component (tool) in order to perform a specific operation. Based on the concept of a locking mechanism, it is possible to integrate a mechanical system with computer in conjunction with electronic/pneumatic devices. In the present study, a locking pin with two springs is used to perform the locking operation. The basic advantage of the proposed locking mechanism is simple in structure and more rigid. A multi-punching system is developed here, incorporating the concept of proposed locking mechanism, which is finally integrated with a computer. The developed technology is successfully implemented in the jacquard weaving system for making punched cards that may be used in different forms for other applications such as turnpike toll receipts and automatic voting systems.
