Examples of this development are very important. • Bottle separation system which allows to pack bottles of any format and diameter on the same machine while maintaining optimal performance conditions. • Wrapping bar assembly without drive chains. This group has no with reliability and efficiency of the parts in contact with the bottles. part subject to lubrication or wear total accessibility, operation with no resistance and can be immediately reset in case of an E-stop. • Tunnel metal mesh belt without side drive chains. The removal of these chains that are highly sensible to the cyclic heating and cooling through the tunnel has reduced to zero the maintenance of the whole tunnel. The stretching of the mesh belt is in fact automatically compensated for by a counter weight assembly. • Powered servo driven film unwinding system preventing any film stretching when pulled from the roll – allows a dramatic reduction of the film thickness with significant material savings for the end user. Furthermore, the absence of stretching of the film increases the accuracy of the centering of the printed film on the bundle.
User friendly technology
Zambelli’s research has also tackled energy consumption for film shrinking and aesthetic improvement of the shrink pack. Unique energy saving heating tunnel design has obtained perfectly shaped packs without wrinkles by a tunnel of reduced length hence reducing thermal waste and machine footprint. The user friendly technology with less moving parts in the machine has a dramatic impact on reducing time needed for installation and commissioning, training customer’s personnel and carry out scheduled maintenance. All together these features reduce the machine’s total cost of ownership (TCO) that is the ultimate customer’s goal. These are only some of the innovative features shared by all the LFT series tray-packers and shrink-wrapping machines, throughout the widest range of capacity available from 15 up to 150 cycles per minute and capable of running product in film only, pad+film or tray+film style. Zambelli certainly have the right machine to help you driving down your production costs.
Flexibility with different formats
An example of performance and good results of the LFT series is the recent Zambelli machines installed by Eko-Vit, Poland and by Drogheria & Alimentari, Italy. Zambelli has installed at Eko-Vit Poland a perfect example of their design philosophy: the LFT70/V tray-packer/shrink-wrapper running at 70 cycles per minute fed with cans – 150, 250, 296, 330, 355 and 500 ml, and glass bottles 275 and 300 ml. Great flexibility with so different product formats handled on the same machine. In-feed conveyor is purposely designed to allow quick change over just by sliding side guides with pre-set positions for the three different formats that can be fed to the machine (hi-cones, multipacks and loose cans). LFT70/V tray-packer/shrink-wrapper is pre-arranged to produce also pad+film or film only, a great feature to respond to future requests from the market. The machine cycle is controlled by Siemens PLC and a 15” touch-screen pc allows the operator to easily monitor all the phases of the machine working cycle thanks to a graphic diagnostic system.
