[Pokayoke Example] Prevention of Forgetting to Tighten Screws with Torque Driver

Achieving prevention of forgetting to tighten screws with a torque driver.

We received a request from a building materials manufacturer stating, "We would like to implement counting management (poka-yoke) for screw fastening operations not only with Makita-style cordless screwdrivers but also with manual torque drivers in our production process." In response to our customer's request, we collaborated with a torque driver manufacturer to equip the torque driver with our poka-yoke transmitter, enabling it to send a signal when screws are fastened with the torque driver. [Details] (1) The transmitter was modified to accurately detect the completion of fastening with the torque driver. (2) The existing poka-yoke receiver already installed on the customer's production line was utilized as is. As a result, it has become possible to introduce counting management (poka-yoke) for torque drivers on-site in a short period. *For more details, please refer to the PDF document or feel free to contact us.
