Human–Cargo Separation Scheme for Safer and Smarter E-Cigarette Production

A leading e-cigarette manufacturer recently faced a critical safety challenge: during material transportation, there was a high risk of collisions between AGV (Automated Guided Vehicles) and workers. Traditional safety measures could not effectively distinguish between people and transport vehicles, limiting both safety and production efficiency.

To address this, a new protection scheme for human–cargo separation has been developed, integrating advanced safety technologies to ensure smooth, efficient, and secure operations.

Core Components of the Protection Scheme

The system combines multiple layers of smart protection to create a robust and reliable safety environment:

• ESS/ESN Secondary Safety Light Curtain – forms the first protective barrier to detect unauthorized access.
• Intelligent Identification Network – built from counter-reflective, retro-reflective, and diffuse reflective photoelectric sensors to accurately detect and classify moving objects.
• WLM Series LED Warning Lights – provide instant visual alarms for nearby personnel.
• ESRS Safety Control Module – enables integrated management and coordination across the system.

This multi-technology approach ensures that both workers and AGVs can operate in the same space without compromising safety or efficiency.

Three Key Technological Innovations

1. High-Precision Intelligent Identification
   The system’s intelligent algorithm distinguishes between people (accidental entry) and AGVs (normal operation) with an impressive 99.99% accuracy rate.
2. Multi-Level Safety Design
   With a response time of less than 20ms, the system achieves Performance Level d (PL d), ensuring fast and reliable protection in critical scenarios.
3. Modular and Flexible Architecture
   The design supports easy expansion and adapts to different factory layouts, allowing manufacturers to scale or reconfigure protection as needed.

Benefits for Manufacturing Operations

By implementing this human–cargo separation scheme, factories can achieve:

• Reduced collision risks between workers and AGVs.
• Increased production efficiency without compromising safety.
• Future-ready adaptability to evolving layouts and production demands.

This solution not only solves a pressing safety issue but also creates a scalable foundation for smarter, more efficient manufacturing in the e-cigarette industry.
