The LABEL•EYE® is a photoelectric sensor designed specifically to sense labels on a roll. Since the LABEL•EYE® is a one-touch AUTOSET sensor and not the conventional "teach mode" sensor, set-up is simple. Position the gap between the labels directly under the sensor's sight guide and push the "Normal" or "Translucent" button. The sensor does the rest, adjusting itself to the perfect setting. Sensing labels has never been easier.
The Label Applicator Process
The LABEL•EYE® is a special purpose gap or slot sensor optimized to sense adhesive labels adhering to a roll of backing paper. The web of labels is directed from a “roll” across a peeler plate or around a sharp edge. As the web passes around the sharp edge of the peeler plate, the adhesive label peels from the backing material. The function of the LABEL•EYE® is to look through the backing paper to detect the "gap" between the labels and signal the labelling machine to stop the dispensing mechanism before the label is completely dislodged from the backing material. With the next "up" label protruding off the end of the peeler plate, it is now perfectly positioned to be applied to the next product as it passes by on a conveyor.
The LABEL•EYE® operates on 10 to 30 VDC and is pulse-modulated to prevent any problems from ambient light. Although designed for label detection, the LABEL•EYE can be useful in a variety of applications such as edge guiding, small parts counting, and splice detection.
