The labeling machine labels labels such as round bottles, and its movement can be roughly divided into two categories.
The first category is wine bottles and beer bottles. The bottle stands up and moves forward, sticking the pre-applied label to the bottle. Here are three different situations:
1. The bottle moves forward intermittently, and when it stops moving, the label is posted.
2. Send the label out for posting during the movement of the bottle.
3. Twist the label in tandem with the moving speed of the bottle.
The second category is small vials. The bottle is lying on the back and the label is rotated.
The biggest problem with labeler movements is the problem of posting, usually with a label coated with a liquid adhesive. Thanks to the presentation of new types of labels such as pressure sensitive, heat sensitive and hot melt, the equipment of various labeling machines has been newly developed. The problems with liquid binders are: initial viscosity, quick-drying function, adherence to the outstanding condition of the coating roll, avoidance of adhesive adhering to the guide rolls, and constraints on the material of the facing surface. Especially in the case of high-speed machines, the choice of binder solvent and the drying time of the solvent are also bound. The heat-sensitive label has its strengths. It heats the adhesive to melt it. After heat reduction, it can adhere to the adhesive for a long time. Then the heating and pressing operation of the labeling machine can be carried out. Because of the strong adhesion, it can be used for various kinds. The information is posted. The advantage of the hot-melt type is that it melts only when heated, and sticks immediately after cooling, and the information that can be posted has a wide range of origins. However, it should be noted that this method is different from the adhesive that is re-condensed in the data. Because of the difference in the type of information posted, there is a risk of falling off due to label drying in the long run.
