Labeling machine workflow

The work process begins with the boxes being fed on a conveyor belt to the labeling machine at a constant speed. The mechanical fixture separates the boxes by a fixed distance and pushes the boxes along the direction of the conveyor belt. The mechanical system of the labeling machine includes a drive wheel, a labeling wheel, and a reel. The drive wheel intermittently drags the label tape to move, the label tape is pulled out of the reel, and at the same time, the labeling wheel presses the label tape on the box through the labeling wheel. Open-loop displacement control is used on the reel to maintain the tension of the label tape. Because the labels are closely connected to each other on the label tape, the label tape must continue to start and stop.

The label is attached to the box with the labeling wheel moving at the same speed as the box. When the conveyor belt reaches a specific position, the label belt drive wheel will accelerate to a speed that matches the conveyor belt, and then decelerate to a stop after the label is attached.

Since the label belt may slip, it has a registration mark on it to ensure that each label is correctly placed. The registration mark is read by a sensor, and during the deceleration phase of the label tape, the drive wheel is repositioned to correct any position errors on the label tape.
