Bauer BK Series Geared Motors for Pizza Packaging Line Conveyors

Published

on

One of the world’s largest food and beverage companies needed an efficient, reliable drive for a pizza packaging line in one of its plants in Italy. The drives power shrink wrapping machine infeed conveyors. The facility had been using traditional stainless steel motors rated at 70-80 Hz. However, to boost production, the speed was increased to 80-90 Hz which created excessive heat causing the drives to fail.

After a careful analysis of the conveyor application demands, Bauer engineers recommended a BK Series right angle bevel geared motor for improved efficiency compared to worm gear solutions. The Model BK06 supplied features a PMSM (permanent magnet synchronous motor) that reduces heat losses from the rotor by 100% and total losses by approximately 25%, while increasing total efficiency by 10% or more. This improved performance translates into lower total cost of ownership, a reduction in CO2 emissions, and ongoing savings that buffer against future increases in energy costs.

Because PMSM motors provide efficiency at a wide range of speeds, it allowed the conveyor line speed to be adjusted up to 80 RPM when needed to meet production schedule targets.

Compact Bauer BK Series models are completely enclosed and sealed against dust and moisture. A hardened wear sleeve and spray ring ensure leak-free performance.

From another Point of View

Published

STOBER presented the new generation of its servo planetary geared motors at the SPS IPC Drive in Nuremberg at the end of 2019. One of the special features of this generation: Each motor series can be directly mounted in any available size. With this variance, STOBER offers ready-to-install drive solutions for machine tools and packaging machines as well as applications in automation and robotics. In order to ensure that the assembly of the new gear units remains efficient even with an increased variety of combinations, the specialist from Pforzheim relied “on digital” when planning the new production line and gained new perspectives through virtual reality.

With the third generation of its servo geared motors, STOBER has developed high-performance and precise drive solutions that are the most compact on the market in terms of versatility and convince by their enormous variance. The gear units can not only be combined with different STOBER motors in direct mounting, but also with all third-party motors of any size via a one-of-a-kind interface technology. A perfect fit for any application.

During the development of the new drives, the STOBER design engineers faced a wide range of challenges: Compared to the previous version, for example, the performance had to be improved and the components had to be built significantly more compact – at the same cost. A balancing act which STOBER mastered primarily by means of new production technologies and optimized assembly lines. “Especially the work and assembly planning, not to forget the optimization of the ergonomics at each of our workplaces, is one of the most important, but unfortunately also one of the most time-consuming tasks”, says Marc Schneider, team leader in gear assembly at STOBER. “Instead of building physical prototypes on the basis of our CAD or Excel data and modifying them again and again, we relied on virtual reality for the design and optimization of the assembly lines in advance”.

Virtual Reality as an agile development partner

With a VR tool by R3DT, a start-up based in Karlsruhe which STOBER chose, entire systems can be simulated as early as the conception phase. By means of VR glasses environments can be experienced one-to-one. A “simple” principle with great effect: 3D CAD data from workstations, for example, are imported into the VR software along with other relevant key figures and processed. At the push of a button virtual prototypes are ready to be used.

“VR glasses on and we are already standing in the virtual environment at the previously designed workstations. With our hands we can reach for virtual tools, check the screwing – without joysticks or other controllers”, Schneider explains.

Frequent testing allows design errors to be detected in good time; corrections in the design or even in the ergonomics of a workstation can be made directly – even in the early planning phase. For STOBER numerous aspects that needed improvement came to light before real prototypes were built.

The resulting real prototypes are very close to being ready for production. In addition to saving an enormous amount of time and avoiding costly subsequent modifications, Marc Schneider is pleased to be able to involve his co-workers right from the start.

“We are very motivated to make our everyday work more ergonomic. Another advantage is that the VR tool gives the entire team the opportunity to experience and learn about new technologies in early stages. In addition, we can now react more effectively in assembly to the ever-changing product mix that our customer requires. An exciting project!”

Wärtsilä’s Data-Driven Dynamic Maintenance Planning solution optimises engine maintenance

Published

By

The technology group Wärtsilä introduces its Data-Driven Dynamic Maintenance Planning (Data-Driven DMP) solution. This latest developed feature enhances the company’s existing Dynamic Maintenance Planning solution by utilising digitalisation and Wärtsilä’s extensive capabilities in analytics. It is an integral part of the company’s Lifecycle Solutions value proposition, and adds further customer benefits and value not possible with conventional DMP solutions.

Data-Driven DMP increases the uptime of assets and reduces lifecycle costs by optimising major overhaul intervals, without compromising operational reliability or engine efficiency.

Furthermore, assets are maintained in prime condition without the need for on-site visual inspections performed by Wärtsilä personnel, since the solution’s digital capabilities reduce the need for such on-site visits. Customer personnel can be trained to take fluid samples and to carry out borescope inspections of engines with remote support from experienced and specialised experts in Wärtsilä’s Expertise Centres.

Leveraging the new capabilities and keeping the engines in prime condition eliminates the need for the usual opening inspection of the engine.

“Data-Driven DMP adds a new dimension to our Lifecycle Solutions’ value proposition, delivering greater flexibility and increased cost savings for the customer. Existing DMP contracts can be changed to take advantage of the extra benefits provided by Data-Driven DMP, should customers wish,” says Frank Velthuis, Director Digital Product Development, Wärtsilä Marine.

The technology for Data-Driven DMP is supported by Wärtsilä’s Expert Insight product, which enables proactive and rapid advice and assistance to be delivered to customers from the Expertise Centres. Expert Insight has been credited with taking predictive maintenance to the next level.

Wärtsilä’s Lifecycle Solutions offering is backed by a combination of the company’s extensive in-house know-how along with AI and predictive analytics. It takes a holistic approach to ensure sustainable and reliable operational performance.

Ziehl-Abegg’s elevator division reaches an all-time high

South-East Asia and Europe deliver a 12 percent increase for the Hohenlohe motor manufacturer

The elevator drives division at Ziehl-Abegg has been running at an all-time high for the past two months. “We have never had such a high order intake in the elevator sector,” says CEO Peter Fenkl. The orders are coming mainly from Europe and Southeast Asia.

2019 had already been a record-breaking year for the elevator specialists at the electric motor manufacturer Ziehl-Abegg: in the final count, it posted sales of more than 72 million euros. In the current year, business in the elevator division has continued at the same record level as in the previous year. “However, the development in order intake since March is far exceeding our expectations,” says CEO Fenkl. “We are currently 12 percent up on the previous year!”

Ziehl-Abegg is benefitting from being located in Germany. In contrast to Southern Europe, where in Italy and Spain many companies are closed, production in Southern Germany is in full swing. Even in the current corona crisis, the supply chain is working and supplies to production are secured, with even kit manufacturers in Spain ordering elevator motors and control units from Ziehl-Abegg in Hohenlohe. “Many of our customers’ finished products end up all over Europe, including England,” explains Sales Manager Dieter Rieger. It’s a similar picture in South-East Asia: the closure of regional companies has created a vacuum for elevator manufacturers, the result is that they are now buying components on the global market – for example, from the German manufacturer Ziehl-Abegg. “A large proportion of the volume is coming from new construction projects,” says Rieger.

The motor division at Ziehl-Abegg is the second largest area of business in the Group. Worldwide, Ziehl-Abegg employs 4,300 people, spread over the areas of ventilation, control and drive technology plus automotive. “It’s during times of crisis in particular that the strength of our broadly-based portfolio becomes evident”, underlines CEO Fenkl.
