Description

An automatic labeling system for a packaged in-mold label This application relies on and claims the priority of the Chinese Patent Application No. 2011.

Technical field:

The invention relates to an in-mold labeling device, in particular to an automatic labeling system for an in-mold labeling device for labeling a label in a package. Background technique:

In-mold labeling has been widely used in petrochemical, daily packaging and food packaging, especially for petrochemical and daily chemical products. In-mold labeling is protected by the high-end packaging industry with its protective, functional and decorative functions. Widely favored. For in-mold labels, it gives a more beautiful color pattern on the bottle than screen printing.

To achieve the labeling process, not only in-mold labels but also labeling equipment are required. As shown in Figure 9, the stacked in-mold label is now placed in the labeling device. This stacked in-mold label needs to be trained in the post-press process to eliminate static electricity, manual finishing, weighing, and manual. In complex processes such as packaging, and during transportation, storage, and rubbing, the labels are prone to static electricity, which causes the labels to stick to each other and affects the normal operation of the labels. Moreover, due to the need for manual finishing and packaging, it is prone to counter-marking and re-marking, which not only causes waste of labels, but also leads to product qualification. In order to overcome the above drawbacks, a packaged in-mold label has been developed. For such a package in-mold label, the existing labeling equipment is no longer applicable, and therefore, a new type of suitable in-mold label is developed. Labeling equipment has become a necessity. Summary of the invention:

The purpose of the utility model is to provide an automatic label feeding system for a package in a mold, the automatic The labeling system can realize automatic labeling of the label in the package, and improve the qualified rate of product molding.

In the above process, when the label in the unfolded in-mold label comes into contact with the contour punch 102, the label 200 is tightly attached to the contour punch 102 due to the action of the vacuum hole 11 to prevent the label from falling. When the robot removes the label, the vacuum device is stopped so that the robot can smoothly remove the label. The above process indicates that the automatic label feeding system of the package in-mold of the utility model can realize automatic labeling of the label in the package, and the efficiency of the labeling is high; since the label in the package does not need manual finishing and packaging, therefore, There will be a phenomenon of counter-marking and re-marking, which will improve the qualification rate of product molding. Since the buffer positioning pin and the top plate are provided, when the profiling punch is punched out, it can realize the unfolding of the package. The label is positioned to prevent the unfolded label in the package from moving due to the punching force, and the label is smoothly carried out.

During the automatic bidding process, if the width of the label 200 is different, the needle mounting plate 14 and the top plate 21 can be adjusted by adjusting the buffer to ensure that the positioning pin and the corner material correspond in the front and rear positions, thereby ensuring the unfolded in-mold label. The reliability of positioning. In addition, when adjusting the buffer positioning pin mounting plate 14 and the top plate 21, it is necessary to ensure that the buffer positioning pin mounting plate 14 and the top plate 21 correspond in the front and rear positions, otherwise it is impossible to ensure that the positioning pin can be inserted into the trim.
