Abstract

Pentwyn Splicers Ltd. designs manufactures and markets a range of products known as yarn splicers. Splicers are specialist products used throughout the textile trade to join yarns together in a manner which is superior to that of the traditional knot.

Splicers use compressed air, at pressures of around 7 bar, to intermingle the fibres of textile yarns. Approximately 60% of splicers are hand held equipment carried by the operator from machine to machine where they are plugged into a compressed air line to operate, although there are some machine mounted versions.

Due to the delicate nature of yarn fibres, exposure to the air blast must be controlled carefully. To ensure reliable splicing it is crucial to control one key parameter; the duration of the air blast.

Pentwyn Splicers Ltd. does offer blast timers, but their design and operation has never been particularly satisfactory. They have a relatively simple mechanical function that involves the use of bleeding air through a flow control valve. The units are difficult to calibrate and are subject to variable performance. In short, the are unreliable.

The application experiment involved the development of an electronic control unit incorporating microcontroller device technology to improve the control of the splicing operation. The microelectronic development will enable the following plans to exploit the technology to be delivered:

  1. The design and manufacture of an electronic timer for application to specific splicers.
  2. The enhancement of the electronic device to provide control and monitoring of parameters other than blast duration.
  3. The application of subtle control functions established through the use of microprocessors to develop fundamentally novel forms of splicer in the future.

Success in the project will enhance the company's competitive position and will result in completely new products. The improved performance will also allow larger and higher value niche sectors in the textile industry to be targeted.

The electronic controller was designed and completed successfully within six months from the start date of the 1 August, 1997. The cost of the electronic controller development was approximately 27,000 EUR. The anticipated payback for this investment will be less than 18 months from product launch, and the improved product will produce a ROI (return on investment) of above 240% over its four year product life.

The lessons learned by the company in integrating electronic and electro-mechanical systems in a small space constraint information will be of use to a wide range of organisations supplying mechanical design products in general. The lessons learned will enable companies to replace mechanical sub-systems used for control and regulation in their products by the use of electronic control modules. The company's experiences will be of special interest to companies in the textile and clothing industries.
