Dynatect’s Gortite® VF Automated Machine Safety Door can increase productivity by minimizing cycle time and maximizing production time. The VF door also limits the depth penetration factor and average approach speed, allowing closer location of the safeguarding device. Unlike light curtains, a physical barrier with safety sensors can save up to 30 sq./ft. of manufacturing space. The door is installed in conjunction with existing machine guard panels on each side of the door to enhance the separation of environments further
Although the VF Door satisfies the need of both an automated roll-up door and high-speed industrial door, application emphasis is on use as a secure barrier. Equipped with a traveling photoeye sensor, the door can come to a full stop in a matter of seconds. It is typically applied to automated production and machine processes that require preventive safety measures such as robotic welding, processing, and transport tasks. The door can contain typical machine/process generated hazards including light debris, fluid splatter/mist, and weld smoke/sparks/flash.
The modular system arrives with top roll header fully assembled; no cutting/drilling/tapping or welding is required for assembly. The default design is not dependent on machines or walls for support. You can also reduce the footprint by eliminating the feet and bolting the door directly to infrastructure.
For accessibility and convenience, all sensor cables are terminated on the motor-side leg column of the door frame to a passive block with industry standard quick disconnects.
The removable, aluminum side column covers provide access for installation, travel adjustment, preventive maintenance, and adding accessories such as interlocks.
Multiple T-slots in the side columns and header allow for structure and accessory mounting. Side columns feature T-slots on the side and back. Custom bracketry and wall-mount adaptation is available.
Attractive appearance enhances your modern facility. All aluminum and steel external surfaces are powder coated (base plate, columns, covers, and top roll header).
The door mechanism moves on maintenance-free ball-bearing based guidance system for smooth, low-wear operation. Non-contact sensors eliminate the need for mechanical cam-switches.
The side columns consist of extruded aluminum profiles and structural 2” square steel tube. Standard travel speed is 44”/second with up to 2 complete cycles per minute, continuous operation. The VF door was developed for more than 1 million cycles. A 1-year warranty is provided.
The door itself is retained in columns to minimize risk of people falling through a closed door (conforms with OSHA guardrail requirements). A traveling photo-eye option (bottom edge sensing and reversing) is available with any controls option. The safety interlock option meets PLe/Cat-4 safety requirements
when combined with appropriate logic and conformance to risk assessment.
Height for end-travel sensors and optional interlock sensors are fully field adjustable. A wide variety of options from “controls-by-integrator” to “turnkey” are available. The standard motor can be mounted in multiple orientations to minimize overall door width.
