Smart Devices For LU Series & PLC Series

1. Skip Stitch Detector

The skip stitch is automatically detected the moment it occurs, the sewing machine is stopped, and it is notified by a buzzer and a red lamp*.
Productivity increased by preventing the spread of sewing troubles and reducing waste!

Monitors skip stitches by detecting the threads across the hook. If any skip stitch is detected, the buzzer sounds, the red lamp lights up, and the sewing machine stops. Therefore, operators can concentrate on their work without worrying about skip stitches. Finding defective skip stitches during sewing reduces the load of inspection work and prevents the outflow of defective products.

* In the LU-2800V series and PLC-2700V series, the error is notified by displaying the error code on the operation panel, not by lighting the lamp.

2. Bobbin Thread Remaining Detector

Automatically detects before the bobbin thread runs out and notifies you with a buzzer and a green lamp*. Possible to avoid sewing troubles in advance, reducing the burden on the operator and improving efficiency!

The remaining amount of bobbin thread is detected by a sensor using a dedicated bobbin. When the remaining amount of thread on the bobbin reaches the specified value, the buzzer sounds, the green lamp lights up, and the sewing machine can be stopped. Therefore, sewing operators can concentrate on their work without worrying about the remaining amount of bobbin thread, increasing the productivity.

* In the LU-2800V series and PLC-2700V series, the error is notified by displaying the error code on the operation panel, not by lighting the lamp.

3. Cover Sensor Unit [Each can be used separately.]

Opening / closing of the eye guard and cover is automatically detected, and when it is open, the sewing machine is stopped from starting. Making it easier to use and improving safety by preventing the accidents due to needle breakage, entanglement, etc.

4. Digital Tension ● Standard equipment for LU-2800V series and PLC-2700V series.

Setting of thread tension can be centrally managed by digitization.
Furthermore, the thread tension is prevented from being changed by the operator’s own judgment.

Numerical control of thread tension settings can improve reproducibility when changing work processes. Since a dedicated control box is required to change the settings, operators cannot change the thread tension, resulting in easier management and higher efficiency.
