Time:2019-10-08 Views:249
      The key equipment of the labeling machine is the core controller PLC, the testing label and the equipment that the product passes through -- the measuring eye and the measuring eye. The normal use of labeling machine and the setting of electric eyes are of vital importance. Here by bo gao logo technology co., LTD. Small make up for you to answer.
      First of all, we should understand the principle of the electric eye. As the name suggests, the measuring eye is used to detect labels. How the measuring eye works: it can identify gaps between labels according to their thickness. Apply to paper labels or other labels of a certain thickness. There are three lights on the eye.
      Green signal lamp: power lamp
      Yellow signal lamp: identification status light (yellow light lights up, indicating signal output)
      Red light: error or warning light
       1. Steps for setting up the electric eye for measuring mark:
      (1) pass the label through the u-shaped slot of the electric eye,
      (2) if you pull the label, the yellow signal light will light up in the interval between the label and the label, and go out in the place where there is a label. At this time, it means normal and can be used directly.
      (3) when the yellow signal lamp is always on or off, it is necessary to reset the electric eye.
      The setting method of electric eye is as follows:
      A. Pass the label through the U slot of the electric eye,
      B. will have labels in the magic eye inside groove, continue to hold the adjustment button 3 seconds, can see the electric yellow lights flashing, then loosen the button, where there will be no label (tag at the bottom of the paper only) on magic eye groove, continue to hold the adjustment button for 8 seconds, and then loosen the button, at this point, the setting is complete.
      C. Pull the label in the electric eye slot, and it can be seen that the yellow signal lamp is off where there is a label, and the yellow signal lamp is on at the interval between the label and the label.
      2. Electrical eye fault of the test mark
      (1) put the label in the electric eye detection area of the beacon, slide the label to obtain and disconnect the signal, and observe whether there is flashing signal lamp in the IO monitoring on the touch screen. If the signal lamp does not flicker, the electric eye may fail or the connection is loose. If the joint is loose, press the joint tightly. If the problem is not solved, consider the fault of the electric eye and replace the electric eye of the test mark in time.
      (2) check whether the label paper has passed through the electric eye detection area of the test mark; if not, install the label paper and pass through the electric eye detection area of the test mark.
      (3) check if there is any dust, powder, broken label, etc., covering the detection end of the electric eye. If there is, please timely clean the electric eye.
      (4) check whether the effective signal of the calibration eye has been adjusted. If yes, please reset the calibration eye. (set according to the operation procedure of the electric eye manual of each model)
      (5) check whether the type of electric eye used is invalid for the material and nature of the label
      If the transparent label is used on the equipment, but the detection eye is a common detection eye, it may appear that after the detection eye senses the measured object, the label will be continuously peeled by the head. The solution is to replace the corresponding property, can normally detect the effective signal of the beacon eye.
      Problems of one kind or another may occur in the process. According to the above steps, the setup is based on the German labor-easy test eye. If it is another brand electric eye, the setting method may be different, you can call the supplier specific steps.
