Adjustment method of electrical eye for labeling machine

Time:2020-05-09 Views:343
      1, because the position of the test object electric eye is related to the timing of the label, so it is necessary to adjust its position, different sizes of bottles need different positions, if the position of the test object electric eye queen mother, will appear too early, causing labeling before, or even less than labeling. If the position of the electrical eye is too much before the test, the label will appear too late, causing the phenomenon of the label askew or the queen mother. (the front and back are based on the man-machine interface faced by the operator, and the forward direction of the bottle on the conveyor belt is the front).
      2, and the marking electrical eye is related to the location of the mark and the length of the mark in advance, so it is necessary to adjust its position, the position required by different labels may also be different, if the location of the marking electrical eye is too high, it will appear that the pre-marking is not enough, resulting in labeling inaccurate phenomenon, or labeling is behind. If the position of the electrical eye is too low, there will be too many pre-mark, resulting in the labeling wrinkle, or labeling near the front.
      Step 1: the current value of red is 144 when the electric eye falls on the gap.
      Step 2: when the eye falls on the label, the current value of red is 4.
      Step 3: adjust the "setting value". About 1/2 of the value of the electric eye falling on the bottom paper (between the detected object and the detected object) and the value of the electric eye falling on the label (the detected object) is (144+4)/2=74. Adjust the "manual button" to adjust the "setting value" to about 74.
      Step 4: move the label or the gap (on the detected object) back and forth at the detection point of the electric eye. At this time, whether the red "signal light/indicator light" can be displayed normally.
