Hazard Area Protection on Die Presses via Safety Light Curtain
Hazard Area Protection on Die Presses via Safety Light Curtain
So-called die presses are used in the metal industry to bend sheets, which apply enormous force to the objects. In order to secure this danger zone for workers during the bending process, a safety light curtain is installed on the side. Individual beams can be deactivated and resolution reduced thanks to the integrated muting and blanking function. Chips or thin sheets are thus not detected and do not lead to unwanted downtimes. Hands or fingers, on the other hand, are reliably detected and lead to an immediate machine stop.

Collision Protection of Overhead Tracks with Laser Distance Sensors Time of Flightin the Automotive Industry
Collision Protection of Overhead Tracks with Laser Distance Sensors Time of Flightin the Automotive Industry
In the car’s final assembly stage, car bodies must be transported along overhead tracks into inaccessible levels and to processing stations. The electric overhead conveyors required for this purpose are mounted under the hall ceiling so that the floor remains unobstructed. In order to avoid collisions, laser distance sensors Time of Flight with wintec are installed on the overhead track carriers. They measure the distance to the carriers in front and thus control the distance between them. Collision-free operation is possible thanks to the range of ten meters and the ability to detect different surfaces at large angles.

Hazard Area Protection in Window Profile Production with Safety Light Curtains for Hand Protection
Hazard Area Protection in Window Profile Production with Safety Light Curtains for Hand Protection
When manufacturing window profiles, mobile system parts such as moving carriages must be able to move as much as possible and be secured at the same time. Zone protection is installed via safety light curtains for hand protection. Thanks to the narrow housings, the protective devices can be ideally integrated into tight systems. You can monitor multiple areas dynamically over long distances. If a safety zone is entered, the system stops. Depending on the number and structure of the areas, the system can continue to operate undisturbed in another zone despite the interruption.
