Weightpack: constant innovation, day after day

In a globalized market, in constant, unexpected change, few businesses can truly boast a history based on the principle of constant innovation, day after day. Weightpack’s roots lie in the example of its founder, Carlo Corniani who, in 1979, had the vision to revolutionize the coeval filling technique: rather than focusing on achieving a certain linear volume, he instead based it on the net weight of the product placed in the container, net of the tare. He was thus able to guarantee consistent product quantity, free from variations in density and temperature, while bypassing the dimensional tolerances of the containers.

The “Net Weight” concept was not, in fact, the first patent filed by Corniani, but it signified a historical change in the history of filling machines the dawn of a new era. In this context the weightpack philosophy began to form, investing every year considerable resources in research and development in order to increase the quantity and quality of proprietary patents. Modular Systems, Direct Drive Plugs, 24 bit weighing electronics and self adaptive power management represent the top of the innovation process reached by the company in the last year alone all technologies that are about to enter the market.

MODULAR SYSTEMS

The heart of the system consists of the filling capping monoblock, which can be coupled to input and output modules.The input modules can be assigned to the type of treatment (blower, rinser, peroxide and steam, PAA and sterile water) or act as a connection with the stretch blow molder. The whole system can, in turn, be coupled to a locking machine or, for the NH versions, to an output module for elimination of the output format change.

The stainless steel draining modules have the same geometry and components, regardless of whether the machine is NH or BH or independently of the type of industry targeted by the machine itself. The modularity principle, on which the design is based, makes it possible to produce independent and extremely reliable systems. Weight pack is able to produce the same monoblocks, regardless of how they are used, guaranteeing a significant upgrade in the level of industrialization and reliability, together with a considerable reduction in delivery times. In addition, Weightpack is able to design and manufacture separable aseptic machines in individual watertight modules.

DIRECT DRIVE RO TARY TRANSFER DRIVE

Thanks to Direct Drive technology, Weightpack is able to guarantee a precise and constant control of both the delivered torque and the vertical load, as well as perfect electronic control in vertical translation and rotation. Any screwing strategy, including the initial counter rotation for twist off caps, can be easily implemented, satisfying the customer’s needs. There is also the possibility, in combination with vision systems, to orient the cap, in order to obtain the best possible result. The plugin capping units are extremely compact, with very low inertia and suitable for any application, from corrosion proofing to aseptic.

24 BIT WEIGHING ELECTRONICS

Next generation electronics, characterized by the use of the EtherCat protocol, allow for the optimization and modularization of monoblock geometries and the interchangeability of free and plug and play tool components.

SELF ADAPTIVE PRODUCT FEED MANAGEMENT

Tankless filling systems guarantee absolute and certified sterilization in the product loop and favor the minimization of production heads and tails.In conclusion, Weightpack is a driving force in the filling sector for the scope of its innovations and for its intrinsic ability to read the market’s current and future needs, with a view to simplification based on the concept of research and development. Just as Carlo Corniani had wanted.
