Robot protection with laser scannersAt the Hannover Messe Industrie (HMI) trade fair, SICK AG used the example of a safety laser scanner with dynamic protective field switching to demonstrate the sensor intelligence of the future. This is the prerequisite for safe interactions between humans and machines in the time of Industry 4.0.

Safety laser scanners from SICK reliably monitor the hazardous area of stationary or mobile machines and systems such as welding robots or automated guided systems. The protection of personnel is the top priority: if a person enters the area, the dangerous movement must be stopped safely. In the established systems, this means that the person is protected but production stops.

In the future, SICK will be able to use intelligent sensor technology within the context of Industry 4.0 to not only ensure the safety of personnel, but to meet ever-increasing production requirements as well. SICK already offers up to four simultaneous protective fields, resulting in a significant improvement in the ergonomics and efficiency of complex machines; for example, in the case of tyre curing presses.

The digital protective fields used today are being replaced by flexible ones. Flexible protective fields are calculated automatically for highly dynamic movements and are adjusted according to the hazardous areas of the robot. Intelligent sensor technology also makes commissioning much easier and quicker. An optimal interaction between intelligent sensor technology and modern machine concepts boosts the productivity of the machine and ensures the safety of employees at all times.

With its extensive portfolio of safety laser scanners, SICK has the right product to suit any requirement – mobile or stationary, for area protection or access monitoring. The compact systems scan their environment in two dimensions using an integrated rotating mirror like an optical radar, and measure distances using the principle of time-of-flight measurement. This produces freely definable protection areas.
