The improvements over the previous machine generation involve essentially the machine control, the drives, and the construction. Thanks to the process-controlled functioning of the new machine control, the individual sequences are overlaid as far as possible, so the labelling process is optimised and significantly faster due to its harmonious motion profile. Servo drives on all axes, as well as the virtually continuous operation of the longitudinal shift unit, ensure the cycle output is increased still further.
The labelling modules, which are equipped with sophisticated servo motor technology, also contribute to a higher level of output. The use of servo drives means it is not necessary to perform reference runs before the labelling operation is begun - so set-up and conversion times are reduced, and the labellers are operational more rapidly.
The robust construction of the labellers also has a positive effect on the cycle output. The axis of the longitudinal shift unit is, for example, designed with even greater torsional rigidity than previously. The machines operate with significantly less vibration, and their travel range can be completed in a shorter time. The simplified construction with its fewer number of deflection rollers accelerates label roll change and makes it even easier, so that downtime is also reduced.
Compared to previous models, menu guidance has been optimised and equipped with an integrated wizard function. The system only needs the required number of cycles to be entered - after that, all the relevant speed and acceleration parameters are adjusted automatically. Thanks to the integration of the Quick Control panel in the labeller housing, distances for the operator are also reduced.
Removal of the vacuum box cover and access to the pusher plate set is quick and easy, and this can be performed without any tools. The necessary service work can be carried out rapidly and in a user-friendly way.
The reduction in time and effort during set-up and service work increases efficiency and has a very positive effect on life cycle costs.
Thanks to their compact design and small footprint, the new cross web labellers can also be integrated into existing production and packaging processes - and if required, they can be retrofitted easily and cost-effectively with inspection systems or additional printers, since they are already equipped with the necessary interfaces.
Another feature of these new models, which are designed for long life and durability, is their high level of reliability - even when running constantly at high output. The harmonious motion profile and the fact, that moving parts have largely been eliminated, make a major contribution to reduced wear and increased service life. Design innovations, such as the improved cable feed, have also significantly reduced the risk of faults.
MULTIVAC cross web labellers are able to run a wide range of label sizes and materials with consistently high labelling quality. The modular design system, as well as the wide range of tailor-made equipment options, enable the labelling solution to be individually designed to the particular labelling and space requirements with maximum output, efficiency, and flexibility, while also making optimum use of the available space and consuming the minimum amount of resources.
All the standard printing processes can be integrated in the labellers. The labellers can also be equipped with visual inspection solutions for checking labels and print. These can easily be retrofitted thanks to pre-prepared interfaces.
Particular importance was attached to safety, especially in view of the high cycle speeds. The constant monitoring of travel speeds and torques ensures that the highest level of process and operating reliability is achieved even at maximum output.
Thanks to targeted minimisation of potential faults, MULTIVAC has significantly increased the reliability and availability of the labelling system. The reduction in moving parts and an improvement in the cable feed also make a significant contribution. The cross web labellers are controlled reliably and conveniently via the HMI of the packaging machine. In the case of long packaging lines, the labeller can also be operated with its own MULTIVAC HMI control terminal, so that long distances for operators are avoided.
The new cross web labellers are already designed for the demands of tomorrow. A wide variety of marking technologies, as well as the modular construction of the labelling solutions, enable them to be perfectly adapted technically and cost-effectively to the future requirements of the particular pack and its required print quality or label position – and always with maximum output and efficiency.
State-of-the-art communication standards such as IO-link and EtherCAT enable the machines to be equipped with the latest sensor technology. In the case of high-output lines, it is also possible to integrate ancillary solutions, such as automatic switching between two cross web labellers. And last but not least, the new labellers are also designed for predictive maintenance.
