We will introduce a case where a "VD-unit" was implemented in the running axis of a stacker crane, establishing a predictive maintenance system linked to operational information. Continuing to operate under excessive conditions without being able to quantitatively assess the deterioration of the wheel axle bearings resulted in a significant failure that required the replacement of the running unit, leading to high repair costs and a prolonged halt in shipments. It has been confirmed that the vibration values tend to increase in proportion to the running speed of the stacker crane. By not relying solely on vibration values, we conduct diagnostics linked to the running speed, achieving deterioration diagnosis of the bearings. [Case Overview] ■ Request: To realize predictive maintenance for the stacker crane ■ Challenge: Unable to quantitatively assess the deterioration of the wheel axle bearings, leading to significant failures ■ Measurement Point: Wheel axle section ■ Solution: Link operating conditions (speed command values) and vary thresholds *For more details, please download the PDF or feel free to contact us.

This is an introduction to a case where a "VD-unit" was introduced to the turbo molecular pump of a semiconductor manufacturing device to establish a system for detecting bearing abnormalities (unusual noises). The challenge was that it was not possible to accurately grasp the lifespan or signs of failure of the pump, leading to excessive maintenance and high maintenance costs. Maintenance personnel recognized that the unusual noises generated by pumps with deteriorated bearings become louder. The "VD-unit" has established a system that quantitatively detects these unusual noises as vibration values. [Case Overview] ■ Request: To prevent sudden failures of turbo molecular pumps and reduce maintenance costs ■ VD-unit Settings - Filter: 1kHz to 10kHz - Measurement Mode: Acceleration - Calculation Mode: RMS, CF ■ Normal State: 0.7m/s² (RMS setting) ■ Unusual Noise Occurrence: 4.5m/s² (RMS setting) *For more details, please download the PDF or feel free to contact us.

We will introduce a case where a "VD-unit" was implemented in the drive motor of a wire saw, and a vibration diagnostic system was constructed in conjunction with a PLC. Maintenance parts were replaced based on on-site judgment, but a significant failure occurred. It took a week to repair, during which the manufacturing line was stopped, resulting in high costs. Thanks to the high detection capability of the "VD-unit," vibrations from the reciprocating motion of the wire are detected. Monitoring is conducted by varying the threshold in conjunction with the speed command value in the PLC. [Case Overview] ■ Request: Reduce downtime caused by sudden failures of the wire saw ■ Challenge: A significant failure occurred, causing the manufacturing line to stop for a week for repairs ■ Solution: Link operating conditions (speed command value) and vary the threshold *For more details, please download the PDF or feel free to contact us.

As a case study of a conveyor system manufacturer, we would like to introduce an example of a predictive maintenance system that implemented the "VD-unit" on a belt conveyor.

We would like to introduce a case where the "VD-unit" was implemented in the pass roller of a winding machine to address the risk of defective lithium batteries. When an abnormality occurs in the pass roller within the winding machine, changes in the tension of the sheet and other factors can increase the risk of defective lithium batteries. There are many pass rollers in the equipment, and we were searching for an efficient monitoring method. We confirmed that the diagnostic capability of the "VD-unit" with its teaching function is effective. Since there is no need to set thresholds for each pass roller, the effort required for configuration is significantly reduced even with multi-point monitoring. [Case Overview] ■ Request: To detect abnormalities in the winding machine early and reduce the risk of defective products. ■ Measurement Points: Near the bearing sections of each pass roller. ■ Solution: Abnormalities are determined based on thresholds created by the teaching function of the VD-unit. *For more details, please download the PDF or feel free to contact us.

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.

This is an example of a control system built by introducing the "VD-unit" to a honing machine (grinding machine) and utilizing the differences in processing vibrations caused by play in the equipment. Defects (poor formation of grinding marks) occurred in the products at a frequency of once every few months, leading to increased costs. The cause was due to play in the equipment, and the timing of maintenance relied on the operator's intuition. As a result of verification using the "VD-unit," it was confirmed that there was approximately a 50% difference in vibration values during specific processing before and after maintenance. Based on data verification, a monitoring and control system has been established. [Case Overview] ■ Request: To prevent the occurrence of defective products using the honing machine (grinding machine) ■ Measurement Point: Near the spindle of the grinding blade ■ Solution: - Confirmed approximately a 50% change in vibration values before and after maintenance, and maintenance is performed when changes in vibration values are detected by the VD-unit. *For more details, please download the PDF or feel free to contact us.
