Automated Barrier Door Shields Workers from Fumes, Sparks and Flying Debris - Booth #B1747

MODEX/ATLANTA (April 9, 2018) – Rite-Hite Machine Guarding has introduced the industry’s most sophisticated automated barrier door, the 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, Rite-Hite Machine Guarding’s new 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. Additionally, the Defender’s roll-up design leaves a minimal footprint into the typically crowded manufacturing cell.
The 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 EN 10218-2 specifications in mind.
“The Defender is the most feature-rich automated barrier door ever manufactured by Rite-Hite Machine Guarding,” said Rite-Hite Doors Director of Marketing Jon Schumacher. “It takes into account all aspects of the new regulations and the demands of the industry as a whole. Given the new OSHA (ISO 13849-1) and RIA (EN 10218-1) regulations, it should appeal to a wider variety of industries than any of our previous automatic barrier doors, including new manufacturing processes and industrial applications including conveyors, industrial elevators and palletizing applications. Additionally, the Defender is a great alternative to light curtains and area scanners, going the extra step to contain the process.”
