    1 From the perspective of main function and control, the labeling position detected by the self-adhesive labeling machine in the past is based on the front edge of the bottle body as the sensitive point Because bottles with different diameters need to make corresponding eye movement or labeling time change If this change is not made, the labeling can not be ensured at the required position of each bottle The current products all have the function of "automatic calculation of label length", which can effectively make up for the above weakness "Automatic calculation of label length" is an automatic control technology formed on the combination of PLC and servo motor technology When the conveyor belt bottle passes the detection of the electric eye, the radius of the bottle is measured, and the Zui bump on the outer circle edge of the bottle is taken as the sensing point of the labeling signal, that is, no matter how small the bottle diameter is, the Zui bump on the outer circle edge of the bottle is taken as the sensing point of the labeling signal, so the electric eye There is no need to adjust the distance from the stripper plate mechanically, and there is no need to adjust the marking time at all This is the automatic control principle of "automatic calculation of label length" This is also the point that people should have function for the sticker In terms of the synchronicity of the control speed, the self-adhesive labeling machine shall not only be equipped with the above "automatic calculation of label length" function, but also automatically complete the synchronous adjustment of the conveyor belt speed, labeling speed, labeling length, etc., which is also the difference from the traditional self-adhesive labeling machine and the guarantee of labeling quality stability The control speed of traditional self-adhesive labeling machine is adjusted by human experience, and the difficulty of human adjustment is that all movements are difficult to synchronize If it is not synchronous, the labeling process will change frequently, resulting in poor labeling quality In the control system, the control system of (PLC + human-machine interface) is the main one Compared with the early single-chip microcomputer (single board computer), the use of general-purpose PLC as the main control device can make the PLC control system achieve the following purposes: (1) more stable and reliable; (2) more convenient maintenance in the future, The upgrade is simpler; (3) it can be easily controlled online with the upper and lower stations In addition, we also need to consider adding a visual system, which can detect, control and alarm the integrity of printing, the status of words, and whether the labeled label is complete or not 2 From the speed of sending label, the speed of printing and the output, when choosing the sticker machine, people often only pay attention to the output of the sticker (i.e how many pieces can be pasted per minute), but fail to comprehensively consider from the speed of sending label, the speed of printing and the speed of rolling and pasting 3 From the perspective of special use, when choosing to label bottles, we often encounter problems of special use For pharmaceutical production, we may encounter: (1) double-sided labeling; (2) similar plastic bottle surface has the phenomenon of "bubble" on the label surface or the label adhesion decreases due to the release agent.
