Self-adhesive bottle labeling machines used to come with mechanically driven or step-motor-driven bottle plates. But Italian machinery manufacturer SIG Alfa has introduced what it calls the first bottle labeler using servo axes. The company says it allows changeover and high-speed running of bottle formats and label sizes without stopping for mechanical cam or software cam table changes.
The former mechanically driven or step-motor-driven machines allowed rotation of the bottle during the labeling process, but could only handle one shape and size of bottle at a time without a cam change. The software camming capability of the servo motors means the bottling machine can rotate bottles while operating at high speed and adjust to different bottle shapes. SIG Alfa is using ELAU's PacDrive automation system.
Beauty-care manufacturer Alberto Culver will receive the first SIG Alfa servo-based machine, which has 16 servo axes and four labeling groups.
