Brief description

Plastic guide rails are a fundamental component of conveyor technology and are used in a wide range of industries. Existing measurement systems designed to detect rail wear require the rails to be partially dismantled and either take measurements at specific points or do not provide continuous monitoring. The aim of this project is therefore to develop a wear sensor based on extrinsically conductive polymers that is integrated directly into the structure of the rails. An associated condition health monitoring system will be used to measure and analyse rail wear continuously and in real time during operation. This will enable the remaining service life of the rail to be accurately predicted and maintenance intervals to be better planned, allowing the guide rails to remain in operation for the maximum possible duration, avoiding unplanned plant downtime and thereby significantly reducing repair and maintenance costs.

Motivation

  • Planning maintenance intervals for plastic guide rails to optimise costs
  • Improving resource utilisation through maximising operational uptime
  • Prevention of unplanned plant downtime and associated consequential damage caused by worn guide rails that have not been replaced in good time

Objectives

  • Development of an electrically conductive compound for use as a wear sensor
  • Development of a condition and health monitoring system to measure the state of wear and predict the remaining service life during operation

Duration

1 March 2023 to 30 September 2025
