Traditional center guiding with mechanical sensor positioners requires two competing control loops: Loop 1 guides the web to the target centerline position, while Loop 2 continuously moves the sensors to chase the web edges as width changes. These loops …
Every width change with traditional moving sensor center guides requires waiting for mechanical positioners to reposition both sensors to the new edge locations. Depending on the distance to travel and motor speed, this can take several seconds to over a …
Yes. Unlike competitor systems that require separate sensors for edge detection and line/contrast guiding, a single [rr sensor] handles both functions. The same infrared sensor that detects physical material edges can also detect printed lines, coating …
The [rr controller] includes Loss of Contrast Logic specifically for this situation. When the sensor encounters a gap where the tracked feature disappears (such as the space between labels), the web guide holds its current position. When the sensor sees …
No. With [rr sensors], you do not need to purchase or install a separate sensor for line/contrast guiding. The same ODC or 1DC sensor family handles edge detection, line guiding, center guiding, and contrast guiding. For most high-contrast applications, …
[rr sensors] can detect and track lines with a minimum width of 2 mm (0.08 in). The sensors also support negative space guiding—tracking the gap between printed features (such as the white space between labels) rather than a printed line. This eliminates …
No. Traditional line sensors have narrow fields of view, requiring motorized positioning to physically move the sensor until it finds the line. [rr sensors] have wide sensing ranges from 48 mm to 960 mm, allowing the sensor to see the entire potential …
Light source selection depends on your application: Infrared (880 nm): Best for most high-contrast applications including black lines on white, coating edges, and foil substrates. Works for both edge guiding and line guiding with the same sensor. White …
Teams from the University of Oklahoma and Oklahoma State University were named first place winners in both Graduate and Undergraduate divisions of the Donald W. Reynolds Tri-State collegiate business plan competition here Tuesday …
Sizing an unwind actuator requires more than knowing the total load weight. The key factors are: Breakaway Force: The actuator must overcome static friction to start movement. This depends on the bearing type: Low-friction linear rail bearings …
