Brückner increases the efficiency of its film stretching lines
Intelligent Line Management:
Simplified line operation and higher line availability
Continually increasing speed and output with ever shorter delivery times and growing demand for quality make running a film stretching line a highly complex business. Film producers and their operating personnel stand before increasing challenges when it comes to guaranteeing a stable and efficient production with the highest quality film.
This is where Brückner’s “Intelligent Line Management” (ILM) comes in. This is an integrated solution which smooths the way for Brückner’s customers’ “Smart Production” and “Industry 4.0”. The focus lies here on a new way of operating lines, putting the emphasis on the process view as opposed to the usual machine view. This new operating concept is supported by an increasing amount of assistant systems.
Along with the “Energy Monitor” which is already used to monitor energy consumption at all line components, Brückner has developed new tools and assistant systems for inline measurements and to directly influence important film values such as temperature, haze, molecular orienteering angle or also density and porosity. For film production this brings a variety of advantages:
• Simplified line operation with significantly fewer process parameters to adjust and intuitive user guidance
• Transparency and traceability of production data
• Targeted inline control of film properties for a consistently high film quality
• Increased line availability through shorter reaction time in case of malfunctions
• Efficiency, productivity and flexibility through assistant systems such as “fast product change” (key word: Just-in-time-delivery) or “energy monitor”
Film producers will find it easier to produce the highest film quality all over the world, independent of surroundings, time, climate and weather conditions.
BOPET lines with 10.4m working widths
Nowadays the established working width for lines that produce biaxially stretched polyester packaging film (BOPET) is 8.7m. For the K 2016 Brückner Maschinenbau will present a 10.4m concept for the first time ever in the world. This will fulfil the demands for higher productivity in BOPET production: The new lines convince with around 20% more output capacity with the proven speeds of up to 515m/min. Film producers can hereby profit from Brückner Maschinenbau’s experience from many successful projects with over 10m working widths, from fewer specific production costs as well as reduced energy consumption and therefore better overall profitability.
BOPP lines: Lower operating costs with higher efficiency
Brückner’s newly designed sliding system for transversely stretched film means speed increases from over 600m/min. At the same time newly developed materials led to a reduction of the lubrication use by more than 50%. The new design in combination with newly developed lubrication is the basis for lower production costs. Furthermore these newly developed lubrication materials are also available for upgrades on current high-performance lines.
A new winder system caters for higher line efficiency. In the future Brückner lines can take 40% more winder length by increasing the winder diameter from 1.55m to 1.8m. More winder length means fewer roll changes and therefore less waste, which effects productivity, changeover time and energy consumption for the entire line.
BOPA: Higher yield on simultaneous lines
Brückner has noticed a growing interest in the market for polyamide packaging films and offers a selection of line types. Brückner’s LISIM (Linear Motor Simultaneous Stretching) simultaneous stretching process is enjoying an increased demand as BOPA film can be produced in the highest quality and with optimized finishing characteristics. For the K the company presents LISIM BOPA lines with a working width of 6.6 meters, instead of the usual 5.1 meters. This increases output by a good 30% and substantially increases productivity.
