Cảm biến canh biên LH500 Nireco - Nireco Vietnam
Line Follower Head LH500 is a sensor that optically detects register lines or patterns printed on a web and, in combination with a controller (*1), can be used to form an EPC (Edge Position Control) and LFC (Line Follower Control) system.
Line Follower Head LH500 stores detected lines as image information, which it uses to perform pattern matching and comparison operations on image information during operation. With this new system, even if register lines and printing accessories are mixed, the stored lines are always tracked.
Giới thiệu sản phẩm
This is an example of using a combination of LH500 and a Liteguide controller with a slitter machine. The register lines or patterns printed on a web are detected using LH500. Then, so that the line always passes through the reference position, the unwinding reel shifts in the opposite direction from the deviation to cancel out irregularity, stretching, shrinking, uneven thickness, etc., of the web, enabling high accuracy slitting.
