Automated Machine Safety VF Door

Dynatect’s Automated Machine Safety Door (AMSD) is an effective solution for increasing productivity and industrial safety. This high-speed door effectively isolates hazardous operations from personnel, equipment, and materials. Yet, it allows for easy access when needed, minimizing cycle times to keep production lines running efficiently.

Beyond its core function as a safety barrier, the AMSD demonstrates versatility. It can adapt to various automated processes, functioning as both a secure barrier and an industrial safety curtain. This automated machine door can be equipped with an optional LiDAR scanner, which senses an obstruction approaching the closing door and quickly stops the door to avoid impact, providing an additional layer of safety for workers and equipment.

The AMSD can be used with existing machine guard panels to create a comprehensive machine guarding system. This system optimizes separation between hazardous and non-hazardous areas within a facility.

Features & Benefits

Easy Installation

  • Modular design includes (2) baseplates with leveling screws, (2) legs, (1) header with pre-rolled curtain assembly and gearbox attached, and (1) motor
  • No cutting/drilling/tapping or welding required
  • Free-standing design not dependent on machine or walls for support (Anchoring/securing to floor is installer’s responsibility)

Safety

  • Door retained in columns to minimize risk of people falling through closed door (conforms with OSHA guardrail requirements)
  • Optional LiDAR scanner (for doorway object detection and reversing function) available:
    • Can be integrated into Dynatect-provided, or user-provided controls
    • Dynatect’s Variable Speed Controller (option) includes integrated logic for control of LiDAR scanner, light curtain, and fixed photo eye. Safety interlock terminations for dedicated machine safety logic.
    • Safety-rated LiDAR scanner also available, and must be paired with a safety relay/PLC
  • Safety interlock option meets PLe/Cat-4 safety requirements when combined with appropriate logic and conformance to risk assessment

Save Space

  • Use of a physical barrier with safety sensors can save up to 30 square feet of manufacturing space.
  • Using the ANSI minimum safety distance formula, the door limits the depth penetration factor and average approach speed, allowing closer location of the safeguarding device:

ANSI Minimum Safety Distance (Ds) Calculation:
Ds = K (Ts + Tc + Tr + Tbm) + Dpf

Ds = Safety Distance
K = 63 inches/seconds (1600/second) – OSHA hand speed
Ts = Stop Time (in milliseconds)
Tc = Response time of machine control (in milliseconds)
Tr = Response time of presence sensing device (in milliseconds)
Tbm = Additional time (in milliseconds) to permit normal wear of brakes
before safety distance is violated
Dpf = Distance (in inches), penetration depth factor

Industry Applications for Automated Safety Barriers/Doors

  • Automated production and machine processes that require preventive measures, such as robotic welding, processing, and transport tasks.
  • Contain common process-generated hazards, such as light debris, fluid splatter/mist, weld smoke, sparks, and intense flash.

The door isolates the CNC machine router, preventing occasional flying debris from exiting the work area. Note: Video references an optional traveling photo eye which is no longer offered.
