Automatic labeling machine purchase guide

As the name implies, the automatic labeling machine automatically pastes the label on the pasted object by the labeling equipment According to different labels, it can be divided into: self-adhesive labeling machine and paste labeling machine So how to choose the right automatic labeling machine? I from the aspect of main function and control, the labeling position detected by the automatic labeling machine in the past is based on the front edge of the bottle body as the photosensitive 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 protruding point on the outer circle edge of the bottle is taken as the sensing point of the labeling signal, that is to say, no matter how small the diameter of the bottle is, the protruding point on the outer circle edge of the bottle is taken as the sensing point of the labeling signal, so the electric eye will peel The distance between the plates does not need to be adjusted mechanically, and the time of marking does not need to be adjusted at all This is the automatic control principle of "automatic calculation of label length" This is also the function that people should have for the automatic labeling machine 2 From the synchronicity of the control speed In the synchronicity of the control speed, in addition to the above "automatic calculation of the label length" function, the automatic labeling machine shall also automatically complete the synchronous adjustment of the conveyor belt speed, labeling speed, labeling length, etc., which is also the difference from the traditional adhesive labeling machine, and also the guarantee of the labeling quality stability The control speed of traditional automatic labeling machine is adjusted by human experience, and the difficulty of human adjustment is that all actions are difficult to synchronize If it is not synchronous, the labeling process will change frequently, resulting in poor labeling quality 3 Choose the control system (PLC + human-machine interface) from the control system Compared with the early single-chip computer (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, it is also necessary to consider the self-adhesive labeling machine to add a visual system, which can carry out real-time detection, control and alarm on the integrity of printing, the status of words and particles, and whether there is a label after labeling, and whether it is complete.
