LABELLING MACHINE COMPRISES MEANS FOR DETECTING ANGULAR MOVEMENT OF SWINGING DETECTING ARM

摘要

The labelling machine consists of a supporting plate (1) carrying a reel (3) with a strip of labels (5) set at even intervals, an oscillating arm to detect the articles to be labelled, and a drive drum (11) for the strip, rotated in steps by a motor. The oscillating arm (9) has an angular movement detector (17) which is linked to a control mechanism to turn the drum by one step each time the arm moves, applying a label (7) to one article. The detector comprises a sensor (69) with a lever (59) to record the movement of the arm, connected to a control element for the drum drive motor.
