Using Safety Laser Scanners for Safety Zone Monitoring on Metal Cutting Conveyors
Risks Associated with Metal Cutting Machine Operation
Hazards from Debris and Sparks During the Cutting Process:
During the cutting process, the high-speed rotating cutting disc generates metal debris and sparks. These particles can scatter into the surrounding area, potentially striking workers and causing injuries such as cuts, burns, or even more severe harm.Mechanical Energy of the Cutting Disc and Its Drive Mechanism:
The cutting disc and its drive mechanism (e.g., motors, transmission systems) possess significant mechanical energy during operation. Improper handling by workers or equipment malfunctions may lead to disc rupture or ejection, resulting in serious mechanical injuries.Limitations of Traditional Safety Measures:
In environments with such potential risks, worker safety is a top priority. However, traditional safety measures, such as physical barriers or mechanical limit switches, may not always provide comprehensive protection.Safety Laser Scanners for Safety Zone Monitoring
Requirements
In a scenario provided by one of our metalworking clients, the conveyor belt and cutting machine are positioned against a wall on one side, with an open walkway on the other. This layout presents significant safety hazards. Consequently, the client has requested that workers be prohibited from walking freely in the area in front of the conveyor belt and cutting machine to prevent accidents.
Solution
Application of DADISICK Safety Laser Scanners: DADISICK safety laser scanners can be utilized for the following safety tasks: Within a flat area (where the angle between the flat protection area and the ground is less than 90°), if the safety laser scanner detects an object entering the protection zone, it will switch the OSSD (Output Signal Switching Device) to the off state, thereby stopping the machine's operation.
