Adjustment of Italy Datalogic-SR21-IR sensor:
Working principle: It belongs to the slot type electric eye, which can judge whether there is a label by the intensity of the penetrating light. It is suitable for labels with different backing materials and sticker label materials.
Detection principle: One side of the slot-shaped electric eye emits a light beam, and the other side receives it. When there is a label in the middle, the amount of received light changes. By setting a critical value, it is possible to distinguish whether there is a label.
Setting method:
When the "READY" light is on, put the self adhesive label in the center of the electric eye focus and pull the label back and forth. If the output signal light ["OUT"] changes, the electric eye is in working state and can be used directly.
Short press the automatic setting button ["AUTO SET"], the green light and yellow light are off, and the electric eye captures the media signal. At this time, the label cannot be moved until the green light flashes quickly.
When the green light is flashing, put the second medium into the focus position of the electric eye.
Short press "AUTO SET", the green light goes out, and the electric eye starts to capture the second medium signal. At this time, the label cannot be moved until the green light keeps on. Move the label back and forth, where the two media are decomposed, the output signal light is on, and the electric eye is set. READY" keeps on, indicating that the electric eye can be used in the switching of the two media.
After seting, then the sticker labeling machine can run smoothly.
