Web and Edge Monitoring

Important in many industries, reliable web and edge guiding ensures a continuous flow of product through machine processes, minimizes downtime and prevents material damage and loss. Sensors are frequently used to monitor and control webs by measuring the web as it travels on the line. Material texture, reflectivity and translucence, as well as the high-speed operation of the equipment can challenge a sensor’s ability to detect and measure the material. Banner’s expertise in a broad range of sensing technologies allows us to offer sensors that consistently and accurately measure web material, keeping it centered on the line for a continuous flow through the system.

  1. Pick and Place Machine Leading Edge Detection

    Fiber optics are an ideal solution for pick and place machines because of their small size. DF-G1 amplifiers can be separated from fibers so the operator has easy access to the digital dual-display screen for data monitoring. Additionally, the cross talk avoidance algorithm allows two or more amplifiers to operate in close proximity to each other.

  2. 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.

  3. Leading Edge Detection of Packages with a Thin, Flexible Edge

    Banner’s LX Series is an economical solution for detecting the leading edge of flat objects, such as the frozen dinner containers. With a web of modulated light, the LX Series part-sensing light screen can detect any item—in any position—passing through the light screen. The LX Series’ response rate 0.8 to 3.2 ms prevents sensing delays and keeps the conveyor moving at the optimum speed for placing dinners in the bucket.

  4. 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.

  5. Ply Orientation Inspection

    Before the operator activates a tire-building machine to form a tire, a PresencePLUS P4 OMNI 1.3 vision sensor inspects the plies to make sure that pieces with opposite biases alternate in the stack. If two pieces with the same bias are stacked together, the formed tire proceeds through the manufacturing process, then fails balance testing and must be scrapped.
