MILWAUKEE — Frommelt Safety has just introduced the industry’s most sophisticated automated barrier door, the Guardian Defender. Designed to guard machinery, contain processes and protect employees from robotic/machine movement zones, the new door boasts patent-pending upgrades to its non-contact safety switch configuration, control systems and interlocking capabilities. It also features a new, more resilient curtain material that resists a wider array of application-driven hazards and offers optional variable frequency drive to control curtain speed. In addition, it utilizes new quick-disconnect cables, which allow for easier installation and integration than comparable barrier doors.
Like its predecessor, the Slimline, Frommelt Safety’s new Guardian Defender is a high-speed, high-cycle automated door that separates machine operators and manufacturing processes. It is an ideal safe-guarding device for robotic welding cells, material handling, automated assembly, palletizing/packaging machinery and other applications that require electronic safe guarding devices. It also contains fumes, sparks, smoke, mist, flying debris, excess noise and other common manufacturing process by-products. In addition, the Guardian Defender’s roll-up design leaves a minimal footprint into the typically crowded manufacturing cell.
The Guardian Defender automated barrier door features a host of innovations, including:
- PLe hold-down mechanism, which locks the door in “down” position to allow for machine “de-energizing” time (necessitated by issues such as roll inertia in the paper industry.)
- Redesigned rotary cam limit switch, encoder positioning and variable frequency drive, to control the curtain’s operating speed and position, dramatically improving the adjustability of door position, speed and control.
- Non-contact interlock switches, manufactured by Jokab, Pilz, Schmersal and Allen Bradley. These provide up to PLe specifications per EN ISO 13849-1 when integrated properly.
- Designed with new EN 10218-2 specifications in mind.
