Prismatic Winding at 100 Metres Per Minute and More?
Using a free add-on, Siemens has extended its proven winder application from the SIMOTION Converting Toolbox with functions for prismatic winding – especially for sensitive materials for battery cells. Here, the objective is to increase productivity, quality and process reliability to the level required for mass deployment in electric vehicles.
The materials require very low, constant web tension, which, until now, had limited production speed. The challenge is to compensate for the ever-changing web length quickly and precisely enough to achieve constant web tension at high speeds. With the add-on, this compensation is now possible either at the winder, unwinder, or via a web accumulator. It calculates the necessary compensation movements at each point of the expanding reel and coordinates the interaction of all involved drive axes in real time. This means winding speeds of 100 metres per minute, and more are within reach.
Siemens AG will be be exhibiting at The Electric & Hybrid Vehicle Technology Expo 2018 at Stand 280.
