[Productivity Improvement Case] Detection of Crease Misalignment in Film Manufacturing

Real-time monitoring of crease misalignment in the bellows manufacturing process! A case of preventing product defects in advance.

We will introduce a case where the "VD-unit" was implemented in the film bellows manufacturing process using material processing machines, establishing an abnormal detection system for crease misalignment. In the film bellows manufacturing process, defects occurred due to misalignment of creases. The cause could not be identified, necessitating a complete inspection after production, which became a significant burden. As a result of vibration verification using the "VD-unit," it was confirmed that the vibration value sharply decreases when misalignment occurs. By monitoring in real-time, we can identify the exact moment when misalignment happens. [Case Overview] ■ Request: To prevent product defects in the film bellows manufacturing equipment before they occur. ■ Measurement Points: Near the bearing sections of each pass roller. ■ Solution: Confirmed the behavior of a sharp decrease in vibration value when misalignment occurs and monitored it in real-time. *For more details, please download the PDF or feel free to contact us.
