How to choose the self-adhesive Labeling Machine(3)
4, from the choice about the quality of labeling
Generally accepted quality requirements for the labeling:
(1) labeling error ≤ ± 1mm, even if re-labeling of the coincident position repeatedly can achieve this value;
(2) after the label affixed surface should fit with the bottle, should be smooth, no wrinkles, no "bubble" phenomenon;
(3) print batch writing legible, no overlap and blur, and batch-bit error <± 1mm.
To achieve the above labeling requirement, then, in addition to quality and fair label manipulation, but also with the device, so the choice should consider the following points:
(1) The labeling of the flatness of the main institutions of justice to see Roll on the design and precision manufacturing, pressure in the Roll on bottle labels and to ensure line contact surface;
(2) drive a high component configuration requirements, due to the action to send the core of a standard high-precision low inertia servo motors, to ensure the quality of labeling, the system closed loop control, and the motor itself can always correct their position in the for their compensation;
(3) detection method and detection components, but also to ensure the quality and labeling labeling production base, technical strength of the manufacturers have changed in the past detection devices detect only label printing imperfections arising, now replaced by the detection method measured thickness, the use of tags and the gap between the thickness of the resulting changes to control the servo-electric operation, which is currently the best detection method, such as greater reliability;
(4) to be able to achieve the perfect label, then the machine control is also very crucial, especially in speed and send the bottle marked speed. Should be noted that the choice of control, production speed signal can be sent by the synchronization system, and then sent to the servo motor calculated by the analysis, requiring both speed matching;
(5) component configuration, as today's high-speed labeling machine is built on continuous operation, and its rapid response to the various components required, all actions are to be completed in an instant, the configuration of the detection devices are also requested. For example, servo motors labeling, labeling motor drives, conveyor motors, reel motors, separation of the motor, inverter, electric eye label, label detection electric eye, the collection of paper to stop Proximity switches, programmable controllers, human-machine manipulation interface elements are configured requirements.

5.1, the choice of label
Self-adhesive labeling machines are used to label roll, label quality will directly affect the quality of labeling, the label printing process, cutting, slitting, static and dust processing is also more important.
