PET, as a widely used plastic material, is widely used in the packaging of various products, especially in the food industry, due to its excellent physical and chemical properties. However, the production and canning of PET bottles is a complex and precise control process, in which the application of driving products is particularly important.
J ü tro GmbH&Co KG Konserven und Feinkost is headquartered in Teborg, Brandenburg and was founded in 1911 as a pioneer in canned product technology.
J ü tro Company focuses on developing and preparing high-quality, storage resistant foods, such as spicy soup bottoms, sauces, and more than 400 convenient products. The company has strict quality requirements for ingredients and production stages, and also requires complete traceability and strict quality standards for bulk trade brand products. To ensure the smooth operation of the factory, all equipment is equipped with reliable technology and optimized maintenance to avoid unplanned failures and shutdowns. Recently, J ü tro has partnered with Nord and other partners to build a new PET bottling production line, in which Nord's reducer and frequency converter products have played an important role.
Focus on customer needs
J ü tro not only attaches great importance to the quality and taste of its products, but also values the flexibility of packaging. Whether it is glass bottles or PET plastic bottles, it strives to provide different types and sizes of packaging. For this reason, the company has specially deployed a super modern bottling system that supports filling of large and small bottles. To meet the new demand, the company hopes to add another PET bottling production line to expand it, so Nord was fortunate to receive an order to provide suitable driving devices for the new bottling and packaging line.
The newly constructed PET bottling production line aims to rapidly bottle tomato sauce, remorad sauce, mayonnaise, and salad dressing to meet the growing market demand. Considering the scarcity of qualified technical personnel, the company initially planned to adopt a high level of automation to ensure production efficiency. The factory is expected to bottle 150 bottles per minute (depending on the specific product), with a shift of 70000 bottles. To meet this production requirement, an optimized and balanced production process is essential.
oneEthernet connection for complete online maintenance
Jan Huesmann, Business Development Director of Nord Electronics Drive Systems, introduced the key points of the project:
The requirement proposed by J ü tro is to adopt a stable driving system with an intelligent frequency converter solution. The frequency converter should also have Ethernet integration function to achieve remote maintenance and similar applications.
After screening, the project team selected the NORDAC PRO SK 550P frequency converter that supports Ethernet connection and has a power output range of 0.25 to 1.5 kW as the design prototype, so that suppliers of different factory components can remotely control and support maintenance of the frequency converter through Ethernet. Through online maintenance, customers can inspect the entire system, identify faults, and evaluate the data of all Nord frequency converters in the factory area.
twoProvide precise drive control for all conveying applications
The first section is to place multiple empty ultra light PET plastic bottles side by side in an upright position. In this section, it is particularly important to precisely adjust the speed through a frequency converter to avoid plastic bottles tipping over and causing malfunctions during transportation. The transportation routes between different stations use ordinary worm gear reducers. In the filling area, the Nord driver used for filling and sealing bottles adopts a smooth surface and nsd tupH treatment, achieving compliant cleanliness and corrosion resistance.
All aluminum drivers in the Nord module system use this surface treatment, which has cleaning agent resistance comparable to stainless steel, but is significantly lighter in weight. Nord drives are widely used in various applications, from main drives to sealing machines. Due to the need for regular cleaning of the system, the drive must be acid and alkali resistant.
oneIntelligent automation is crucial
In the subsequent process, the bottles will be sealed and packaged. In this section, it is particularly important to run the system at high speed and coordinate the control of the conveyor line drivers.
From bottle preparation to filling and packaging, each machine's drive unit is equipped with Nord's frequency converter, which can smoothly perform multiple tasks such as product conveying, sealing, and packaging. We are very satisfied.
Nord's NORDAC PRO SK 550P control cabinet frequency converter is very compact, space saving, and has an integrated Ethernet interface. Through this interface, up to 7 frequency converters can be integrated into higher-level control systems using CAN bus, without the need for each of these seven frequency converters to occupy a separate Ethernet interface, which is one of the obvious cost advantages.
The NORDAC PRO SK 500P deployed by J ü tro factory integrates four Ethernet protocols, with PROFINET being one of them. In addition, the frequency converter in the project adopts vector regulation to maintain a constant speed. Different speed controls can also be achieved through analog input. Nord provides a complete set of data modules and device files, making it easy for different partners to implement automation strategies related to drive technology. This is also one of the obvious cost advantages, which can bring practical benefits.
twoHigh quality service: professional, practical, and fast
Dieter Kohr stated:
Nord's service is excellent, capable of performing various tasks perfectly and to the extreme. We are very satisfied with the proposed solutions, which have clear ideas, practicality, and fast deployment, making it easy for us to implement without obstacles.
J ü tro also stated that it is necessary to further invest in automation. "We are considering adopting a new overall concept to optimize the current manual execution of finished product stacking work." In Kohs' view, "we must constantly improve factory efficiency and reflect on ourselves: has speed increased? Has safety increased? Has it become better?"
