The beginning of the working process of the flat labeler is that the box is fed to the labelling machine at a constant speed on the conveyor. The mechanical fixture separates the boxes by a fixed distance and pushes the box in the direction of the conveyor. The mechanical system of the labeler includes a drive wheel, a labeling wheel, and a reel. The drive wheel intermittently drags the label belt to move, the label tape is pulled out of the spool, and the label wheel is pressed against the box by the labeling wheel. An open-loop displacement control is used on the reel to maintain the tension of the label strip. Since the labels are closely connected to each other on the label strip, the label strip must be constantly stopped and stopped.
The label is affixed to the box with the labeling wheel moving at the same speed as the box. When the belt reaches a certain position, the label belt drive wheel will accelerate to the speed matching the belt, and after the label is attached, it will decelerate to a stop.
Since the label may slip, it has a registration mark on it to ensure that each label is placed correctly. The registration mark is read by a sensor, and during the deceleration phase of the label, the drive wheel will be repositioned to correct any positional errors on the label strip.
