[FA Site Improvement Case] I want to visualize the number of defective products during equipment downtime.

Improving Quality: Identifying the Number of Defective Products through the Visualization of Casting Equipment Error Time!

We will introduce a case study of improvements in FA (Factory Automation) sites proposed by Patlite. Due to errors occurring in the casting equipment, the machine stopped, causing a drop in internal temperature and leading to the production of defective products. However, the downtime could not be monitored on-site, resulting in an inability to confirm the number of defective items. To address this, we introduced the layered information display light "LA6." Upon receiving a signal of an abnormal occurrence, the "LA6" displays the downtime on a timer. By increasing the red timer display in stages from 1 to 5 every minute, it became possible to confirm the downtime from a distance by the number of lit segments. [Case Study] ■ Current Situation - For equipment that experienced an abnormal stop, the person in charge measured the time and identified the number of defective products. - The downtime could not be monitored on-site, and the number of defective items could not be confirmed. ■ Proposal - With the timer display function, the display increases every minute from the occurrence of an abnormality, allowing the downtime to be confirmed from a distance by the number of lit segments. - Wiring is simple, requiring only one additional wire alongside the conventional signal light. - Display time, display color (21 colors), and patterns (15) can be changed using editing software. *For more details, please refer to the PDF document or feel free to contact us. https://www.patlite.co.jp/
