Automation ensures high process quality for large quantities
The Brückner Group, together with their daughter company Brückner Maschinenbau, operates the world’s largest component assembly plant for biaxially oriented film production lines at its Topoľčany site in Slovakia. A new assembly line for roller chain systems has now been commissioned there. During the stretching of plastic films, these special systems transport the film web through an oven-like device and stretch it by a factor of up to 10. In the process, enormous stretching forces have to be absorbed, especially in the case of polyester films (BOPET), which are transmitted by so-called clips. The roller chain systems are therefore of decisive importance in the more than 150 m long lines.
The new assembly line enables the production of over 10,000 clips per month, a capacity increase of a good 30%. Automation solutions and quality assurance tools specially developed for assembly processes of this kind are responsible for the high throughput combined with high quality:
- Poka-Yoke measures in components and assembly fixtures
- Force-displacement monitoring in joining processes
- Torque and rotation angle monitoring
- Positioning of components by means of robots with optical systems
- Completeness and dimensional checks with optical measuring systems
- Automatic recording of process data with statistical evaluation
Brückner customers thus benefit from a consistently high level of quality through optimization of production processes – even with increased throughput. This is an important decision criterion, especially in times like these, with high demand for film stretching lines.
