What Is The Working Principle Of The Labeling Machine

The working principle of the labeling machine is that the cartons are conveyed to the labeling machine at a steady speed on the conveyor belt. The mechanical fixture separates the cartons from each other at a fixed distance and pushes the cartons in 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 in motion, the label tape is pulled out of the reel, and at the same time, the label tape is pressed against the carton by passing through the labelling wheel. An open-loop displacement control is used on the reel to maintain the tension of the tape, because the labels are closely connected to each other on the tape, so the tape must be constantly started and stopped. Labels are applied to cartons with the labelling wheels moving at the same speed as the cartons. When the conveyor belt reaches a certain position, the label belt drive wheel accelerates to a speed that matches the conveyor belt, applies the label, and then slows down to a stop. Due to the possibility of slippage of the label tape, 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 tape deceleration phase, the drive wheel readjusts its position to correct any position errors on the tape.
