Introduction
Industrial robots have revolutionised manufacturing by enhancing precision, speed, and productivity. Nevertheless, although the use of robots improves efficiency and output, they also pose new workplace risks if proper safety measures are not implemented. The safety of the industrial robot is thus very important for protecting workers and maintaining production while adhering to regulatory standards.
This blog examines industrial robot safety, outlines key safety standards, highlights key safety features of robotic systems, and explains why safety in manufacturing is important to all Indian manufacturers.
What Are Industrial Robot Safety Standards?
Robotic safety standards for industries are guidelines and rules that aim to ensure the safe operation of robots in manufacturing. These standards specify how the robots should be designed, installed, used, and maintained to reduce risks to workers and equipment.
These safety standards help manufacturers develop clear guidelines that minimise these risks and ensure safe collaboration between humans and machines.
Commonly Followed Robot Safety Standards
Manufacturers around the world follow internationally recognised robot safety standards to ensure safe operations. Indian manufacturers also use them as guidelines when enacting safety measures for industrial robots in their facilities.
The commonly followed safety standards include:
ISO 10218 is the most recognised safety standard for industrial robots. It is divided into two parts:
ISO 10218-1: Safety requirements for robot manufacturers.
ISO 10218-2: Safety requirements for robot system integrators and users.
This standard concerns robot design, installation, and operation.
ISO/TS 15066, in particular, deals with collaborative robots, or cobots. It offers rules for safe interaction between humans and robots, such as acceptable force limits and safety design considerations.
ANSI/RIA R15.06 is used in North America but is also referenced across the world. It provides safety rules, risk assessments, and safety precautions for robot systems.
IEC 60204-1 addresses the electrical safety of industrial equipment, including robotic systems. It is used to ensure safe electrical construction and installation in manufacturing settings.
Essential Safety Features in Robot Systems
The modern robotic systems have several safety features to avoid accidents and ensure smooth working.
Some necessary safety features are the following:
- Emergency stop buttons enable the operators to stop the robot immediately in case a dangerous event takes place. Such systems should be visible and easily accessible.
- Fencing or physical barriers are also used to ensure that the workers do not enter the robot’s working zone when it is operational.
- Light curtains create an invisible protection shield around the robot. When a person crosses the beam, the system automatically stops the robot to prevent harm.
- Interlocks make sure that machines stop automatically in the event of the opening of protective guards or doors.
- Most modern robots include speed and force controls that restrict their movements in the presence of humans. This feature is particularly significant for collaborative robots.
Importance of Training and Maintenance
Even the latest robot safety standards cannot guarantee protection unless they are well-trained and maintained regularly. Human consciousness and operational discipline are essential to robot safety.
Employee Training
Workers interacting with robotic systems should be provided with training on:
- Safe robot operation
- Emergency procedures
- Understanding safety zones
- Determining possible risks.
Inspections done on a regular basis should include:
- Examining safety sensors and emergency stop functions.
- Checking mechanical parts for wear or damage.
- Verifying correct robot programming and calibration.
Benefits of Following Safety Standards
Enforcing effective robot safety offers both operational and organisational benefits.
- The greatest advantage is that they safeguard workers from possible injuries due to robotic systems.
- When safety measures are properly implemented, robots can operate efficiently without significant disruptions from accidents or technical issues.
- Scheduling regular maintenance and safety checks helps in avoiding unexpected breakdowns and production delays.
- Adherence to recognised safety standards helps manufacturers meet safety regulations and prevent legal claims.
Conclusion
Industrial robots are transforming manufacturing by promoting efficiency, precision, and scalability. But the ability to successfully introduce robotics to production floors requires strict adherence to industrial robot safety practices. We can secure a faster, safer, and more resilient manufacturing ecosystem in the future by focusing on adequate safety measures today.
