The new HEUFT TORNADO R is able to apply wrap-around labels to up to 60,000 containers per hour using either a parallel or a linear transport system. The HEUFT development team has equipped the labeller with a specially developed servo-controlled belt drive and not with standard rotating gears so that it can do this particularly accurately and carefully. It adapts to different container sizes exactly and rotates the bottles and jars which have been fixed in platforms by means centring bells harmoniously. Consequently wrap-around labels made of paper or cut foil can entwine them completely. The rotation speed as well as the height of the up to six nozzles which can be individually activated for the initial gluing can be adapted to the most different container shapes as required. The result: a particularly simple and fast brand change.
The nozzles apply the smallest spots of glue onto the rotating containers in a well-measured and careful manner. These glue spots pull the respective label out of the magazine. A thin line of glue is applied at the end of the label at the same time so that the overlap can be stuck precisely and brushed on carefully. The closed hot glue system of the HEUFT TORNADO R reduces glue consumption to a minimum compared with a conventional roller application. At the same time it ensures that the glue is protected from ambient air and contamination. This reduces upkeep and in-creases the operating reliability of the machine which has been constructed so that it is particularly low-maintenance and wear resistant. The integrated control cabinet makes fast and uncomplicated installing and commissioning possible.
The standard broken container detection in the infeed and optional features for an extensive final product check provide additional benefits. Thus the HEUFT TORNADO R can be equipped with highly efficient modules for a precise label and closure inspection. Fill level, internal container pressure, BBD and barcode checks can be integrated as well as a serial fault detection which emits a switch-off pulse before it is too late. Containers which have been identified as being faulty can be removed reliably from the production flow by means of rejection and laning systems. Automatic sampling functions assist internal quality assurance. HEUFT has developed a convincing solution yet again with the new wrap-around labeller which has proved to be very worthwhile in daily practice. Like all the devices which HEUFT will showcase from 14 – 19 September at the dinktec 2009 exhibition in Munich the new wrap-around labeller will be working.
