Web Tension & Guiding
Special requirements call for special solutions Erhardt+Leimer offers high-precision web
guiding for various applications as managing director Matthew Rust explains.
F
or decades the Erhardt+Leimer group headquartered in Germany has been world leading in the area of automation and inspection technology for production on moving webs.
The company recently presented its new
EL.NET technology at the ICE in Munich.
EL.NET optimises production processes with a digital, web-based system architecture with network and IoT support.
INTELLIGENT TECHNOLOGY FOR INDUSTRY 4.0 PROCESSES
In an
EL.NET control system, digital E+L components connect together to form a network and in this way make possible straightforward, quick integration into the customer’s network.
EL.NET also permits the easy integration of sensors from other manufacturers in use at the customer. All devices automatically and selectively exchange data relevant for optimal control
within a production plant. With
EL.NET it is possible to connect together up to 255 control systems in a network. Here, the data acquired at all levels of the production process make up a decisive part of the automation. These data create a high degree of transparency and make it possible to monitor and to optimize processes in real time – and therefore to minimize downtimes and scrap.
Every
EL.NET device is equipped with an integrated web server via which the data are exchanged. This feature permits user-friendly, prompted commissioning, optimisation and maintenance via web-based management – that is, using a standard web browser without the need for special software. The
EL.NET components also include digital edge and color line sensors, controllers, and brushless – and therefore wear-free – actuating drives. PoE is used for the wiring and the supply of power to the devices, a simple solution.
Commissioning is also quick and trouble-free in the spirit of ‘plug and play’. The components flexibly adapt to new requirements, minimize retooling times, and thus guarantee efficient production. Integrated fieldbus interfaces and optional fieldbus modules ease the connection of E+L control systems to a customer controller.
APPLICATIONS IN BATTERY MANUFACTURING AND PRINTED ELECTRONICS In addition to classic converters, the customers supplied include battery manufacturers as well as manufacturers of printed electronics. Here very special requirements often need to be met, for example a particularly high accuracy while guiding film/foil webs through the process. Or it is necessary to avoid any material abrasion by means of the usage of materials specially matched to the process to prevent even minimal contamination of the material produced. For this purpose E+L offers customized solutions.
For the production and further processing or coating of anode and cathode materials as well as separator films for lithium-ion batteries and other storage elements such as fuel cells, E+L offers complete system solutions tailored to the industry.
These solutions include web guiding and web tension control, inspection systems for checking coatings as well as measuring systems for the measurement of distance, width and grammage.
The operators of battery plants and their suppliers, who are primarily based in Asia, and for some time also increasingly in Europe and the USA, profit not only from the many years of experience of the German Erhardt+Leimer headquarters, but also from the E+L sites in England, China, Japan, Korea and Taiwan, among others, that ensure professional advice, the quick availability of material and skilled local service.
