Abstract

A labeling machine includes a container conveying unit adapted to convey a container from a feed-in end to a take-out end. A container sensor is disposed adjacent to the conveying unit, and generates first and second signals upon detection of leading and trailing edges of the container, respectively. An encoder unit is associated with the conveying unit, and is operable so as to generate distance information to indicate distance advanced by the container. A label applying unit includes a label applicator plate disposed adjacent to the conveying unit. A controller activates the encoder unit upon receipt of the first signal from the container sensor, and determines the diameter of the container by inspecting the distance information from the encoder unit upon receipt of the second signal from the container sensor. The controller activates the label applying unit so as to be adapted to attach a label to the container when the label applicator plate is aligned with a central plane of the container.
