utomation is on the rise in the highly-specialised market for glass-processing machines. Here, companies are seeking complete
drive solutions from a single source, looking for suppliers and partners with whom to cooperate from design to the implementation and commissioning of such new machines. One example is Bsolution, a provider of high-quality glass-processing machines, who chose to cooperate with Italian drive specialist Bonfi glioli, a valued supplier of complete, customised drive solutions.
Flexible and reliable
The Italian company Bsolution has been manufacturing sophisticated glass-processing machines for over 30 years, covering specifi c tasks such as grinding and edging of double- glazed windows and tempered glass. For its latest glass-processing machine series Speed Arris, it required increased productivity and effi ciency. There were two key challenges Bsolution faced – innovation and service – so it needed a partner that could supply the components and have the know-how for optimised design and commissioning. Together, the partners co-designed the loading cycle – making it a lot faster; improved the production with new functions; and optimised the unloading with a double conveyor. To meet Bsolution’s requirements,
Bonfi glioli’s experts developed a customised solution that includes the entire drive train. This consists of the BMC 440 motion controller, ANG (Active Next Generation) servo inverter, BMD servo motor and the TR precision planetary gearbox from Bonfi glioli’s Performance Line. With this, machine performance improved a whopping 15%. The ambitious project focused in particular on two machine-processing modes of the

Speed Arris: seaming and rough grinding of glass. Compared to the previous version, machine startup was made faster thanks to a simplifi cation and better organisation of the machine’s parameters. Its HMI was made user-friendly and intuitive, greatly simplifying operations. Another added feature is the use of the ISO code for a direct link with the design language and an immediate translation into precise machine movements that allow easy production of the desired shape.
High-performance motion controller The biggest advantage of the Bonfi glioli BMC440 is its high-performance level, especially in terms of axis synchronisation. It represents the optimal solution for complex, up to 24-axis applications. The Speed Arris uses a so-called “on-fl y load” concept, which means that the only operation the operator has to perform is to place the glass sheets on the loading belt. The mode requires a very high level of axis synchronisation to ensure high-quality processing of the glass. Another advantage comes from the reliability and ease of use of the motion control functions. Axis coupling is designed to facilitate programming and reduce errors. This results in time savings during application coding. The BMC 440 has up to 256 I/O and is particularly suitable for CPU-intensive and complex applications. It allows access to motion features in combination with the ANG servo drives, ideal for performing complex movements with accurate synchronisation. Its OPC-UA and MQTT functionality ensure local and remote connectivity with full responsiveness to the needs of digital integration for smart manufacturing. The ANG servo inverter series has been specifi cally designed to off er higher performance, especially through fi rmware
features, such as the Touch Probe function, which is mandatory for the “on-fl y load” system. Thanks to a new integrated microcontroller, advanced functions such as cyclic synchronous positioning mode through cubic interpolation, brake control and feedback contact evaluation are integrated. With this proven servo inverter series,
Bonfi glioli off ers the most comprehensive connectivity with the most advanced control technology and the highest power density.
Meeting the highest demands Bonfi glioli BMD servo motors are exceptionally compact, permanent magnet synchronous motors with low inertia. Thanks to the high-quality magnets made of neodymium, iron, boron and rare earths and their excellent design, they meet the highest demands in terms of precision, dynamics and speed. It was precisely these properties that were the focus of the redesign of the new glass-processing machines. The BMD motors are equipped with the latest encoder technology, optimised for operation with frequency inverters such as the ANG as well as precision planetary gearboxes such as the TR. Thanks to the optional additional internal fl ywheel mass, excellent control behaviour can be achieved for applications with high inertia. The TR series of precision planetary gearboxes have very low backlash and high overload capacity, Their modularity, wide ratio range and optimised lubrications ensure high reliability and the best possible fi t to meet a wide variety of application requirements.
