AUTOMATION OF THE QUALITY INSPECTION Whether steering knuckles, wishbones, crankshafts, pistons or excavator teeth - when it comes to forged chassis and engine components, but also non-automotive systems, Bharat Forge CDP from Ennepetal is a sought-after supplier. And that worldwide. CDP, part of the Indian Kalyani Group, has been forging steel for 175 years. For this, the specialist for complex closed-die forged parts uses automated production lines. The quality check is also largely automated at Bharat Forge CDP. Only in this way can the extensive quality tests required by the automotive industry be carried out economically. 08

TOGETHER INTO THE DIGITAL FUTURE DIGITAL EXPERIENCE MADE BY BLUMENBECKER Improve processes, work more efficiently and safely, reduce the error rate, develop new products and services, offer customers added value: These are topics that concern companies in all sectors. COMMUNITY IN THE INTRANET "In order for us to be successful in 20 years' time, we need to absorb technological developments, understand them and adapt them for Blumenbecker," says Group Managing Director Dr. Wolfgang Fink the need to deal with new digital developments. In order to bring together the knowledge of the various corporate divisions with more than 30 locations in Germany and abroad, the Blumenbecker intranet has been a digitization community since 2016. Everyone who wants to help shape the digital progress of the corporate group can exchange ideas with like-minded colleagues and form interdisciplinary working groups. The “Digital Champions” inform each other about the current status of their projects at regular workshops. DIGITAL EXPERIENCE DAY: EXPERIENCE THE TECHNOLOGY OF THE FUTURE CLOSE UP MORE DIGITAL In summer 2017, the ›Digital Champions‹ EXPERIENCES met for the first time for a Digital Experience Day. Here, the 50 participants were able to immerse themselves in the technologies of the future and experience digitization projects at first hand. Well-known partners had been won for this, including the Fraunhofer Institute, which was represented with two technical highlights, the aerial drones and the HoloLens package station. 13th
DIGITAL EXPERIENCES WITH A WOW EFFECT At the individual stations, the participants saw short demonstrations and took action themselves. Links to my own topics were quickly found. How does it feel when data glasses support the packaging of goods or give instructions for the repair of a machine? What kind of work can aerial drones do? What does artificial intelligence do? How can a strap-on exoskeleton make physical work easier? There was a lot of knowledge and inspiration on these and other future topics. "We want to involve as many employees as possible in the digitization process, constantly broaden their horizons and provide new impulses," describes Dr. Fink the chosen path into the digital future. Astrid Blumenbecker, majority shareholder of the Blumenbecker Group, emphasizes that cross-company and cross-border exchange is particularly important. “This is the only way we can avoid inventing the wheel twice. «14

IN 12 DAYS Overhaul in the Brökelmann + Co oil mill In Hafenstrasse in Hamm, things are going like clockwork. OIL EXTRACTION WITH MILLS AND EXTRACTION This is where Brökelmann + Co produces edible oil on a large scale. In 1226, shortly after the city was founded, the first oil mill was built in style: rapeseed, sunflower, diestel, frying and Hamm. In 1845 fried walnut oils that the owner-managed company rich Brökelmann and colleagues acquired the Hamm oil mill under the house brands Brölio and Noury ​​as well as ei- acquired. Today, more than 170 years later, the mills are sold by the trade. Feed, meal remains at the heart of edible oil production. Here and fatty acids complete the range. The flowers are pressed into the grains after cleaning and Walbeck Industrie-Service is your partner for maintenance zen in screw presses. On this way and maintenance of the technical systems. This is where Brökelmann wins two thirds of its oils. The edible oil specialist also uses what is known as extraction. A process in which the oil is extracted from the seeds with the help of hexane gas. HIGH-TECHNOLOGICAL PROCESS WITH 130 DRIVES "Today, the production of edible oil is a high-tech process," explains Frank Tüttmann from Blumenbecker Industrie-Service and adds: "At Brökelmann there are more than 130 motors, gears, Pumps and fans in action. In order to reliably process more than 1,500 tons of oilseed every day, it is important that every single part functions smoothly. «19
DEMANDING REVISION IN EX AREAS Every 18 months, Brökelmann largely shuts down its systems in order to carry out a comprehensive overhaul. This was also the case in autumn 2017 with Blumenbecker as a partner. As soon as the machines came to a standstill, quick and competent action was required in order to keep downtimes as low as possible. The ambitious target was: 14 days for 130 drives. A real challenge, especially since there are 110 drives in the extraction hall. An area in which the highly explosive gas hexane is used. In order to be able to maintain the explosion-protected machines, specially trained employees and special tools are required. Ironically, only seven maintenance days were planned for this sensitive area. But before the Blumenbecker specialists were allowed to get started, they had to make sure that the extraction hall was free of explosive hexane. »Blumenbecker carried out all the work on schedule and to our full satisfaction in the short period given. «Alexander Steinweg, Head of Mechanical Maintenance, BRÖKELMANN + Co - Oelmühle GmbH + Co ASSEMBLY MANAGEMENT ALWAYS ON SITE Finally the green light was given and the overhaul work began. The service technicians set to work at full speed. After all, the drives not only had to be serviced, but also recalibrated and given a test certificate. The assembly management was constantly on site, in a specially installed construction site container. In this way, Blumenbeck was able to react quickly to unforeseen situations and additional work. It paid off. Instead of 14 days, the Blumenbecker team only needed 12 days to overhaul the 130 drives. 20th

KATOWICE A CITY FOR A SECOND LOOK © Wojciech Radwański Katowice will never win a beauty award. Compared to neighboring Krakow, the city is a newcomer. There are neither 700 year old buildings nor romantic marketplaces. And yet Katowice is worth a trip. Because what looks unattractive at first glance turns out to be a place with many hidden charms on closer inspection. Katowice is a young city. It was only founded in the 19th century and received city status in 1865. Coal and steel industries contributed to the rapid growth. Today it is the largest city in Silesia with around 300,000 inhabitants. The past few years have awakened the former working class city from its post-industrial slumber. Today Katowice is considered to be one of the most innovative, culturally dynamic and economically liveliest regions in Poland. THE ›KATOWICE MODERN‹ Katowice has shaped a building style: ›Katowice Modern‹. If you walk through the streets with your eyes open, you will discover this unadorned and unadorned style in many places. Polish architects were often inspired by innovations from the West. One example of this is the “Skyscraper” by Tadeusz Kozlowski, built in 1934, a 14-storey steel frame building. At that time the tallest building in Poland and one of the tallest in Europe. There are also a number of beautiful Art Nouveau buildings. 32
INSIDERT TIPS NIKISZOWIEC MINERS 'Settlement The Nikiszowiec miners' settlement is definitely worth a visit. It was built at the beginning of the 20th century as a residential area for the employees of the Giesche colliery. Nine large blocks of flats made of red bricks are grouped around inner courtyards. Numerous gate entrances reveal the view and the way there. Not far away is the former coal mine of the Wilson mine. The massive building now houses an extraordinary gallery for contemporary art. CULTURE IN MANY FACETS Art and culture play a major role in Katowice. The city is home to several orchestras, has a music academy and has an active jazz scene, which can be found in the city's many clubs. The culinary offer ranges from traditional Silesian to exotic cuisine. There is also no shortage of cafes. Whether it's a nostalgic pastry shop, contemporary espresso bar or hip café, there is something for every taste. DISCOVERING KATOWICE Anyone wanting to discover Katowice can get there quickly by plane. Accommodation in the city center is inexpensive. The communication works well in English and partly also in German. Detailed information is available at www.inyourpocket.com. A handy travel guide with all the important information can also be downloaded here.

IKEA is the world's largest manufacturer of wooden furniture and is known for attaching importance to maximum efficiency in the production of its furniture. Most IKEA furniture consists of standardized modules. The Scandinavian furniture giant is increasingly relying on so-called sandwich elements from which tables, cupboards, beds, chests of drawers and shelves such as the popular KALLAX are constructed. The sandwich elements consist of frames that are filled with lightweight materials such as honeycomb paper. The sandwich process gives the furniture a stable structure, reduces weight and reduces the consumption of raw materials. AUTOMATIC GLUING AND JOINING OF FRAMES For the production of sandwich frames, Blumenbeck Engineering Polska implemented a 50 meter long production line for the IKEA plant in Lubawa, Poland. “A very complex system in which we CONTACT PERSON has combined the gluing and joining processing modules for the first time,” explains Rafał Wójcik, Technical Director Deputy General Industry Division at Blumenbeck, “nothing like this has ever existed before! “It took a year to develop, build, automate and install the system, on which Blumenbecker Engineering worked closely with technology partner Armech. All components were specially designed and manufactured by Blumenbecker for IKEA Industry, the production branch of IKEA. NINE DIFFERENT FRAME TYPES Nine frame types can be manufactured on the production line: Frames in different sizes and thicknesses, optionally with or without a center bar. Via Rafał Wójcik an operator terminal can be switched quickly and easily from one Technical Director Deputy frame construction type to the other General Industry Division.

SMART DOLLY IS CALLING Intelligent positioning system for airport ground equipment 41
SMART DOLLY INTELLIGENT & REMOVABLE Individual service intervals Transmission of the load status A normal day on a large German flight - want to change together. Blumenbecker develops port: airport tugs whiz across and for over 30 years has been building airport ground equipment with one or more trailers, and also takes care of their maintenance and repairs, so-called dollies, in tow. The dollies attitude. Now the specialist for dollies is developing, transporting luggage and freight or distributing passenger stairs and the like along with the consumables. However, a number of the transport trailer team led by Hon.-Prof. Dr.-Ing. Klaus Richter from standing abandoned on the airfield and in the neighboring Fraunhofer IFF an intelligent location system for zenden halls around. “At a large airport, airport ground equipment. Hundreds or even thousands of dollies can be put down in a disorderly manner, «says Ralf GEZIELTE INFORMATIONSVERMITTLUNG Herzog, Managing Director of Blumenbecker Technik The heart of the development are radio sensors, the GmbH. The result: a lot of search work for the tug - to be attached to the dollies. These GSE tracker drivers, especially when it comes to fully conveying the exact position and finding the right transport trailer in real time. A situation status information of the dollies to a central on, the Blumenbecker and the Fraunhofer Institute for control center. This is where the information from all IFF factory operations and automation in Magdeburg transport trailers come together. The system knows ex- 42

The system forwards this information to the tractor drivers on the airfield, who can then specifically control the desired dolly. MARKET READY IN AUTUMN 2018 A pilot project has been running at Leipzig Airport since February, in which the intelligent positioning system is subjected to a thorough practical test. For this purpose, 30 airport ground devices were equipped with a Ralf Herzog radio transmitter and a corresponding radio technology manager installed. The product is planned to be ready for the market in autumn 2018 at Blumenbecker Technik GmbH. T: +49 34636 714-60 [email protected] 43
3 questions for ... Hon.-Prof. Dr.-Ing. Klaus Richter Alternative location systems have their problems with buildings. How is that with the Smart Dolly? “It is true that GPS-based positioning systems do not work reliably near large buildings. Often the radio connection even breaks off completely.That is why the Smart Dolly uses a local positioning technology that determines the position by measuring the field strength. In this way we can reliably record every location, even if the dolly is next to or even in a closed building. In addition, there is the energy-saving LoRa wireless technology from the Internet of Things, which has a long range and guarantees data transfer to the control center permanently and in real time. «44
Specifically, please: What benefits does the Smart Dolly offer airport operators and service providers? »The intelligent location system allows logistical processes at the airport to run much more structured than before. This is immensely important in times of increasing air traffic. Anyone who cannot build new runways or terminals must use the existing infrastructure as efficiently as possible. Smart dollies help. Maintenance also benefits from the smart factor of the transport trailer. Operating profiles can be created on the basis of the transmitted data. These determine the individual load and calculate the next Hon.-Prof. For each dolly. Dr.-Ing. Klaus Richter maintenance appointment. Such precise maintenance - head of the field of competence for material flow technology and systems at the Fraunhofer Institute for Factory Operation ensures permanent safety and functionality and automation IFF, head of the department for operating equipment and saves resources. «Material flow technology at the University of Magdeburg Can the intelligent location technology be transferred to other industries? " In any case. We are currently supporting a company in the development of intelligent plastic pallets. The so-called tagging of reusable pallets enables seamless goods tracking, free from production and storage to the customer. The empties management can also be optimized through the location technology. Stable plastic pallets are finding their way into open pallet pools. «Maintenance required 45
