Description

Full-automatic labeller of carousel formula of circular arc product trade mark
Technical Field
The invention belongs to the technical field of labeling machines, and relates to a rotary disc type full-automatic labeling machine for circular arc product trademarks.
Background
The label bears information such as trademarks, parameter descriptions, operation and use, and is an indispensable packaging accessory of product brands, but labeling precision of the labels is not high, the precision is mostly +/-1 mm, especially, high-end products (such as door handles, electric appliance handles, notebooks, electronic chips and the like) have high requirements on attractiveness, correction and firmness of the labels under special occasions such as high temperature, low temperature and motion, the current semi-automatic labeling is matched with manual operation, manual positioning and manual loading and unloading are carried out, labeling requirements of current products cannot be met, and the following problems difficult to overcome mainly exist:
1) in order to prevent the label from being scratched and rubbed off in the using, moving or transporting process, the label is preferably attached to a circular or square pit, for example, a switch label of a door handle and an electric appliance handle needs to be arranged in pits of arc-shaped surfaces at two ends, so that great difficulty is brought to the positioning, automatic labeling, automatic conveying and automatic labeling of products and labels, and the labeling has to be completed by manual label tearing and manual auxiliary positioning at present. The existing label is made into a sheet material in a door opening array type and a door closing array type, a plurality of label grooves are required to be pasted on one product, the label has direction requirements, detection features and marks which can be automatically identified do not exist between the label and the plurality of label grooves, and the label is not designed to be frequently pasted in a wrong way in a mistake-proof manner, so that the rework cost is high.
2) To make the label durableThe label is prevented from being degummed under long-term high temperature and low temperature (70 to-50 ℃ in extreme case), the labeled product is required to be subjected to high and low temperature resistance tests of +120 to-60 ℃, and the test result shows that the firm degree is at least more than 80-90gf/m2So that the fastness of the label is larger than the conventional requirement of 60-70gf/m2In order to achieve the strength requirement, the label has to be made to be less than the industry minimum label standard (5mm × 10mm), the adhesion of the label is much greater than the industry-available peel adhesion requirement, even if the vacuum suction pressure is adjusted to 90-100gf/m2The label cannot be smoothly peeled off from the base paper, so that the label is difficult to be peeled off by machine adsorption, which becomes an insurmountable obstacle for automatically peeling off the label by a machine.
3) At present, each label for labeling is realized by adopting an intermittent mode of starting and stopping to realize the processes of label feeding, label stripping, label sucking and labeling, the motor traction speed, the torque force, the label feeding tension, the label feeding speed, the label feeding long step distance and the actual tension are required to be set constantly at equal intervals, and the accurate labeling of the label can be realized only when the motion precision and the position precision of each part are coincident. However, in the actual operation process, the diameter of the label tape roll is continuously reduced, the unreeling tension is continuously increased along with the reduction of the diameter, so that continuously increased inertia impact is generated, the inertia impact is accumulated and increased to enable labels to be loose, the label feeding position is deviated, the labels of the first half roll of the roll can be normally pasted, and the labels of the second half roll of the roll are gradually inclined and failed in pasting.
4) The biggest obstacle of the prior labeling equipment for realizing full automation except for label feeding deviation, label sucking failure or deviation sucking is that the label slides and deviates in the process of high-speed transverse movement or rotary movement to the position of a labeling object product after label sucking. No automatic correction labeling equipment aiming at label suction exists at present after retrieval.
5) The constant friction force of a single friction mechanism adopted at present causes the set frequency of the traction label feeding equipment which continuously increases the tension after continuous labeling to be reduced and is asynchronous with the extension working frequency of a label cutter. When the extension working frequency of the label knife is finished, the traction label feeding device does not reach the set frequency, so that the lag of signals detected by the detection electric eye is unstable and asynchronous, the label peeling position and distance are deviated from the set value, and the label is sucked partially or even can not be sucked partially due to the fact that the label is deviated from the back or the front.
The retrieval shows that no mechanism for correcting the tension of each stage and the overall tension of the traction and index feeding exists at present. At present, no equipment for adjusting the friction force according to the label stripping tension required in different overall labeling stages exists, and the requirement for synchronizing the label pulling and feeding frequency and the label cutter stretching working frequency cannot be met.
