COMPUTER CONTROLLED LABELING MACHINE

摘要

A computer controlled labeling machine (10) is used to apply labels to an article (15) such as a beverage container. The apparatus and methods provide particular advantages for applying stretch labels (203) and/or labels (52) with tactilely sensible indicia (56) such as braille markings, to articles (15). The computer control system (20) provides structure (18 & 31) for controlling the speed and orientation of the labeling apparatus (10), including the vacuum drum (35) the relative speeds of the label unwind roll (92) and label pick-up vacuum drum (35) to thereby control the amount of lab el stretch, and for timing when the liquid application station (122) applies th e liquid to form the tactilely distinguishable markings (56). It also controls timing of the label cutter (521), rotation of the container turret (13) and associated apparatus to provide precise control of the labeling operation.
