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.
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.
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.
