Sizing, Profiling and Guiding Clear Objects
Banner Engineering has created a special class of EZ-ARRAYs specifically designed to detect clear objects in clean industrial environments. By customizing standard EZ-ARRAY receivers to successfully detect low contrast and operate at a lower sensing range (30 to 1500 mm), Banner has enabled EZ-ARRAY Clear Object Measuring Light Curtains to detect translucent objects such as glass and clear webbing.

Debarking Control
As a log moves toward the debarker, an EZ‑ARRAY receiver determines the total number of beams that are blocked. It sends an analog signal to the debarking station logic controller, which determines the diameter of the log and adjusts the log grippers and debarking blades to the log’s size. Accurately determining the log's size provides process stability and prevents damage to the debarking machine.
-
Carton Dimensioning
Banner’s EZ-ARRAY measuring light curtains detect items as small as 5 mm wide with an edge resolution of 2.5 mm, and have high excess gain for detecting opaque objects. These features allow for reliable detection and measurement of packages that pass through the light curtains. The total number of beams blocked for each pair indicates the size, which is sent to a sorter as an analog signal. A PLC then diverts each carton to the appropriate storage location.

Sensor solutions to detect a low contrast edges of glass on conveyor in a clean industrial environment where equipment is regularly exposed to high temperatures

Log Measurement
In this application, an EZ-ARRAY measuring light screen is being used to measure the length of the log. The EZ-ARRAY determines the total number of beams that are blocked by the log and communicates the length of the log to an operator station by sending the information to the system controller in the form of a MODBUS RTU-485 output. The operator station controller then provides a number of options to the operator, who selects which cuts are made.

Carpet Web Detection
It's much easier and more cost-effective to measure and monitor these transitions while the web is running than risk expensive waste in post-manufacturing inspections. As the carpet web passes through a pair of EZ-ARRAY measuring light curtains, the two sticks configured for Nap Detection mode monitor the process in action. The EZ-ARRAY detects the selvage edge and tufting edge and sends data to the web control system, which can then make necessary adjustments to keep the carpet in line.

Carton Sizing
Cartons moving on a conveyor pass between three pairs of EZ-ARRAY measuring light curtains. The total number of beams blocked for each pair indicates the size, which is sent to a sorter as an analog signal. A PLC then diverts each carton to the appropriate storage location.
