When the automatic labeling machine is working on the assembly line to label, the equipment will be missing the label. At this time, it is generally due to the problem of the label itself that the operation of the labeling machine causes the missing label.
The label detection electric eye signal point on the labeling machine equipment occasionally fails to reach the correct position, resulting in a label in front of the self-adhesive labeling machine not finished, the traction motor has stopped, and after the second electric eye senses the object, the label Just complete the positioning point that was not completed when the last labeling was completed, so that the object is completely covered with the label, that is, the label is missing.
Therefore, we can use the stop mark delay on the labeling machine, so that each signal of the detection label electric eye can complete a cycle. If the above description of the reason for missing the label appears, it means that the label positioning cycle has not been completed, so the label stop delay can be used to allow the label to travel a short distance after the label positioning is completed, so that the label detection and positioning can complete a cycle. (This method is only for labeling with low precision requirements. If high-precision labeling is required, it is best to improve the label)
If none of the above methods can solve the problem, replace the target measuring electric eye to verify whether it is a problem with the electric eye, and if so, replace the target measuring electric eye.
