[Improvement Case] Key Points for LCD Conversion of Production Line Andon Display Boards

Examples of maintenance with reduced man-hours and space-saving in relation to the amount of displayed information.

Here is an example of improvements made to the production instruction system. The Andon system, which was installed to monitor the production status of the production line, used incandescent bulbs. This meant that when process changes occurred, it was necessary to replace the acrylic panel on the front, resulting in maintenance work at heights and incurring costs for heavy machinery, leading to increased expenses. To address this, we adopted an LCD panel for the Andon. By connecting the computers installed in the office and on-site with the PLC in the control panel within the line via serial communication, it became possible to control the Andon display screen from a location away from the site using a computer. [Case Overview] ■ Challenges - The frequency of bulb replacements was becoming shorter. - Visibility was sometimes poor due to external light interference. ■ Results - The hassle of bulb replacement was eliminated. - Visibility from a distance improved. *For more details, please download the PDF or feel free to contact us.
