So we speak in general about
- Clamping hazard with robot, welding jig or workpiece
- Injuries due to impact of robot arm or welding torch
- Welding eyes
- Burnt skin by welding light
- Hearing damage
- Lung damage due to poor smoke extraction
- Cutting by sharp edges
Safety is a critical aspect of working with robot systems, especially in systems with multiple stations where operators are active. There are several measures that can be taken to ensure the safety of operators working with robot systems. One important safety feature is the emergency stop button, which allows the operator to immediately stop the robot in case of an emergency. This button is usually located on the teach pendant, a handheld device used to control and program the robot
Another important safety consideration is the use of hardware zone security for the first axis of the robot or the track of the robot. This feature prevents the robot from moving into a workstation that has not been reset for production. The zone detection of the robot operates two safety switches, which are separated from the robot software and monitored by the safety circuit
It is also important to ensure that operators receive proper training and understand the safety procedures associated with working with robot systems.
In summary, safety around robot systems with multiple stations where operators are active involves a combination of safety features, proper training, and adherence to safety standards and guidelines.
The safety around the robot systems can be described as follows:
1. Zone protection
Zone protection is an important safety feature in multiple zone robot systems. It prevents the robot from moving into a workstation that has not been reset for production. The zone detection of the robot operates two safety switches, which are separated from the robot software and monitored by the safety circuit.
In a single station robot system, zone protection is not needed because there is only one workstation and the robot is not able to move into another zone.
2. Walk-in protection
- Light curtains
- Sliding screens
- High-speed roll-up door
- Step mat
- Scanner
3. Fences and service door
