[ABC-NT-02] Automatic Bobbin Changer – Solution to Improve Productivity and Maintain Stability in Industrial Sewing Lines

[ABC-NT-02] Automatic Bobbin Changer – Solution to Improve Productivity and Maintain Stability in Industrial Sewing Lines

In the garment industry, especially in large-scale production factories, every second of machine downtime directly impacts productivity, costs, and delivery schedules. One of the most frequent causes of interruptions is bobbin changing. Although each change takes only about 20–40 seconds, when accumulated over an entire production day, the wasted time can amount to hours, leading to a 5–10% decrease in productivity.

Understanding this challenge, Nhất Tinh has researched and developed the [ABC-NT-02] Automatic Bobbin Changer – a solution that allows sewing machines to operate continuously, minimize manual handling, stabilize stitch quality, and reduce labor costs. This is one of the smart auxiliary devices ideal for modern sewing lines, especially for those aiming for complete automation.

1. Why You Should Equip an Automatic Bobbin Changer

• Save bobbin change time: No need for the operator to stop the machine, remove the old bobbin, and manually install a new one.

• Maintain production speed: The machine stops for only a minimal time, then resumes sewing exactly where it left off.

• Reduce errors: Eliminates sewing with nearly empty bobbins (which can cause thread breakage or skipped stitches), minimizing defective products.

• Optimize manpower: One operator can handle multiple machines at once.

2. Operating Principle

The [ABC-NT-02] is integrated with intelligent sensors and high-precision mechanical structures:

1. Thread level detection: The sensor detects when the bobbin thread is nearly depleted.

2. Safe stop: When the preset threshold is reached, the controller automatically stops the sewing machine.

3. Bobbin replacement: The feeding mechanism removes the old bobbin and installs a pre-wound new one.

4. Resume sewing: The machine continues exactly at the stop point, maintaining stitch alignment.
