The customer's production lineup spans hundreds of varieties, and they must produce products of varying lengths and quantities on a daily basis.
Although they have a production schedule, managing it is extremely complex because the quantities and varieties change depending on the situation.
Consequently, various issues arise on the shop floor, such as program call errors and time-consuming changeover operations during setup.
Addressing these issues requires major software implementation, which is often impractical.
We proposed **“Utilizing 2D Codes”** to address their challenges.
In this case study, we prepared three types of 2D codes categorized by “workpiece type,” “length,” and “production volume.”
We built a system enabling simultaneous automatic switching for:
① Machining programs,
② Loader programs,
③ Production volume changes.
The 2D codes are read by connecting a code reader to the machine. We also provided the software functionality to capture the data.
Operators simply scan the corresponding 2D code when changing workpieces to complete the software change.
The implementation of 2D codes has delivered the following benefits:
- Significantly reduces the effort required for frequent configuration changes
- Effectively prevents machine collisions and tool damage caused by human error
- Earns high praise as a simple system that requires no large-scale software implementation
While software and IoT are often perceived as "large-scale and complex," our options, such as this "small-scale IoT," are also available.
