LABELLING PET planet Insider Vol. 18 No. 10/17 www.petpla.net 38 Different container types, different materials, one solution Flexible labelling The new EvoDeco Multi labeller from Sidel is designed to make it easy to apply labels to different types of container made with different materials, such as PET, HDPE, and glass. It can manage different formats and dimensions for a wide range of SKUs (Stock Keeping Units) by using three different modules: one for applying self-adhesive labels; one for cold glue labelling; one for roll-fed labelling. The EvoDeco Multi is capable of running at rates of up to 81,000 containers per hour. Attention has been paid to ergonomics and operator safety. Easy operating, cleaning and maintaining are allowed by its open structure, with no frame, for much less machine downtime. New brushless motors integrated within the labelling modules remove the need for lubri- cation and achieve energy savings, while the multiple module format ensures optimum flexibility. The three different modules avail- able are easily and quickly inter- changeable: Self-adhesive labelling module The self-adhesive labelling module is designed to apply labels at high speed with increased efficiency, the advanced tension control enabling greater stability and precision in positioning the labels. It also deliv- ers the flexibility that manufacturers need in applying labels to a variety of containers of different shape and sizes. Highly effective and efficient acceleration and deceleration ramps ensure that, even at high speeds, the stress affecting the labels as they are handled is kept at a reduced level. To avoid label carrier breakage and to ensure the correct alignment of the containers being labelled for a flaw- less “no-label” look, an air-dancer mechanism also makes sure that the labels are not under any stress at any point. Cold glue labelling module Even under extreme production conditions, such as long run opera- tion and high temperatures, the cold glue labelling module is claimed to be a reliable process designed to undertake the application of pre-cut paper or metal foil labels to a variety of container types at medium to high speeds. The station is claimed to be environmentally friendly with short cleaning times, and a fully washable design, offering high levels of flexibil- ity, applying labels with great preci- sion and keeping material waste to a minimum. Roll-fed labelling module The roll-fed labelling module uses hot glue to apply wrap-around plastic labels. Having an integrated glue tank enables this module to melt and circulate hot glue in smaller quantities while retaining control of the application process. This solu- tion allows for reduced consumption of glue, as of overall waste. Cleaning can be carried out automatically by a device installed on the vacuum drum that works during consistent produc- tion. The roll-fed labelling module can attain speeds of up to 60,000 labels per hour and when the carousel is connected to two roll-fed labelling stations, an output rate of 72,000bph is achievable. Furthermore, when three roll-fed stations are used, it becomes possible to label at 81,000bph. The new EvoDeco Multi label- ler was developed to apply all labels, even thin labels, wash-off labels and self-adhesive labels with precision. Such accurate positioning is pos- sible through new brushless motors integrated into the labelling modules together with a visual system utilising cameras to place the labels correctly whenever applied in a predetermined position upon the container. This means that material waste is kept as low as possible. www.sidel.com
