At both open sides of a robotic work cell, a pair of EZ-SCREEN safety light screens are linked—or cascaded—in an L-shaped configuration to guard the access point both vertically (reducing separation distance) and horizontally (providing continual sensing). Up to four pairs of EZ-SCREEN light screens can be connected.

Personnel Protection with Fixed Blanking and Reduced Resolution

The EZ-SCREEN safety light screen uses fixed blanking and reduced resolution (also called floating blanking) to allow flat boxes to enter the machine. Fixed blanking allows the safety light screen to ignore the boxes, and reduced resolution lets it ignore slight variations in the box height. If the supply of boxes runs out, leaving the fixed blanked area clear, the EZ-SCREEN ligted curtain stops the machine so the operator can safely refill the carton supply.

Perimeter Guarding with Mirrors

To guard the perimeter of a tube bender work cell, two free-standing corner mirrors are set up to reflect the sensing field from the emitter, around the perimeter’s corners, to the receiver. Using corner mirrors is an economical way to make use of the range of an EZ-SCREEN safety light screen by guarding multiple sides of an area with one emitter/receiver pair.

Heat Stake Machine Safeguarding

In this example, two sides of a heat stake machine require guarding because of separate operator load and unload stations. On each side of the station, two safety light screens protect workers; one with a 48" vertical light screen for area guarding and one with a 12" inclined light screen to guard the point of operation where the tool is loaded and unloaded.

Depalletizer Guarding with Muting

Banner’s Type 4 EZ-Screen with a muting is ideal for depalletizer stations with robots because the screens ensure safety standards are maintained while allowing for a free flow of pallets, increasing throughput. The muting allows for a pallet skid to be transferred without shutting down the conveyor or robot cell, helping optimize product flow throughout the distribution center. There is a timing function set at a constant speed that allows for a continuous flow of pallets.

Machine Safeguarding in an ESD-Sensitive Environment

In this application, machine operators require access to the wafer carrier station. The EZ-SCREEN ESD safety light curtain system is configured to safeguard the process and operator using emitters, receivers and mirrors to enclose three sides of the station. Safety light curtains allow quicker, easier access than physical barriers while preventing machine movement if the operator reaches into the hazardous zone.

Manual Load Weld Cell

Banner’s EZ-SCREEN® series safety light curtain system is a well established solution for the harsh requirements of welding equipment. With the ability to cascade (series connect) multiple segments together, configurations such as this horizontal/ vertical pair are easily implemented with standard hardware (no master/slave models).

Depalletizer Guarding with Muting Pair

The design of our EZ-SCREEN muting light curtains allows for a free flow of pallets while keeping the dangerous area guarded to shut down the machines if any workers were to enter the space. The muting option on the EZ-SCREENs lets a pallet skid be transferred without the need to shut down or reset the machine, which would usually slow down the production line. The muting option is necessary in the beverage industry for certain assembly procedures to run smoothly.

Safe Material Access

In this application, a hazardous work cell is completely guarded to prevent personnel from entering the area. In order to allow parts and material to flow into the area efficiently, entry and exit zones will be left open. The EZ-SCREEN safety light screen is positioned in front of these zones and will stop the hazardous motion of the machine if an operator tries to reach or enter through these areas.
