Dynatect’s Gortite® VF Automated Machine Safety Door can increase productivity while making your processes safer. It’s intended to safely isolate hazardous operations from other industrial processes, material, equipment, and people, while still allowing access to it. The door is installed in conjunction with existing machine guard panels on each side of the door to enhance the separation of environments further.

This high-speed industrial roll-up door is designed to minimize cycle time and maximize production in industrial environments. It satisfies the need of both an automated roll-up door as well as a high-speed industrial door, but with an application emphasis on it being used as secure barrier in automated processes. The door is equipped with a traveling photoeye sensor, that can bring the door to a full stop in a matter of seconds.

Overview of Gortite® VF Automated Machine Safety Door’s Key Features

Automated Machine Doors Improve Manufacturing Safety

Featured Application: VF Door Installation

Installation at a Manufacturer of Plastic Cases in Cannon Falls, Minnesota. The Gortite® VF Door was chosen for this application to improve safety and housekeeping. The door isolates the CNC machine router, preventing occasional flying debris from exiting the work area.

VF Door Motor Phasing & Testing

Window

Need to see through to the other side? One or more clear windows can be optionally added to the Gortite VF Door to allow for safe supervision of the isolated processes. Standard window size is 18 by 18 inches. For welding applications, red or bronze OSHA compliant UV windows are available.

Safety Sensor Options

These safety sensor options are available with any control system option.

Sensor for detecting interference and supporting door-auto reverse function:

• Traveling Photoeye (bottom edge monitoring)
• Fixed Photo Eye(s) for sensing interference while door traveling closed
• Fixed 40” Light Curtain

Door Hold-Down Switch:

• Latches door in closed-position, controlled by signal from machine

Door Closed Safety Interlock Switch and Safety Relay:

• Helps meet PLe/Cat-4 safety requirements when combined with appropriate logic and conformance to risk assessment
• Optional safety relay shipped loose or integrated into operator control unit
• Safety circuit wiring required during installation

Note: The installer must ensure that the door, its controls, and any safety devices conform to applicable safety standards

Control System Options

Motor Mounting Options

• In-Line Motor Mount (facing front, facing back, above top roll header)
• Right Angle Motor Mount (up, down, front, back)

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 (D_s) Calculation:
D_s = K (Ts + Tc + Tr + Tbm) + Dpf

Ds = Safety Distance
K = 63 in/sec (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 ms) to permit normal wear of brakes
before safety distance is violated
Dpf = Distance (in inches), penetration depth factor

aka Laser Protection Door

For an Alumaflex (aluminum slat) roll-up door, for laser protection applications, see the Laser Protection Door page.
