Web edge sensor.

Web edge control from led light arrays to the laser light array edge detection control is a typical application for light array sensors position measurements of the object edge generally of fast moving film like or woven roll material are used to control the drives and feed mechanisms in production equipment. 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. This information is transmitted electrically to a hydraulic controller for final control action. The sensor se 44 uses ultrasonic sound to detect the web edge.

When the web reaches the air gap the impulses are weakened. Our ultrasonic sensors scan the web edge with a pulsed ultrasonic beam. The sensor should be positioned behind the positioning roller as near to it as possible. Its light weight small size and insensitivity to ambient light make it ideal for most web guiding applications.

The model 31510 edge guide sensor is designed primarily for photoelectrically sensing the lateral edge position of materials in motion in particular web material of an opaque quality. This avoids standing waves. Bst north america inc po box 7816 madison wisconsin 53707 usa phone. The model 31510 is available in two basic model options.

The greater the web tension the module of elasticity and the required correction the longer the infeed outfeed and transfer paths should be designed. Is a fork sensor for scanning the edges of sound impermeable materials such as foil or paper. Experience has shown that these paths should be the equivalent of 60 to 100 of the web width. This is why the bks is ideally suited for the web control of highly transparent foils light sensitive materials materials with greatly varying transparency and paper subject to high paper dust loads.

Additionally the true edge detection allows for higher precision and accuracy in web position correction. 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. The bks ultrasonic edge sensor. This monitoring solution includes sensor modules which automatically collect data from integrated or connected sensors and transmit them to the cloud and can be.

The new sensor technology allows for a true precision of 0 0635 mm which the current technology cannot provide. This enables the sensor to precisely recognize the web edge.
