[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 in the casting equipment, the machine stopped, causing a drop in internal temperature and leading to defective products. However, there was a problem in that the downtime could not be grasped on-site, making it impossible to confirm the number of defective products. Therefore, the layered information display light "LA6" was introduced. Upon receiving a signal of an abnormal occurrence, the "LA6" displays the downtime as a timer. By increasing the red timer lights 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 - The equipment that experienced an abnormal stop was timed by the person in charge to identify the number of defective products. - Downtime could not be grasped on-site, making it impossible to confirm the number of defective products. ■ Proposal - With the timer display function, the number of displays 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 easy with just one additional wire along with 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/
