Ralf Lampe, Sales Director of the Corrugated Board division, together with CORRUGA.EXPERT, elves into the journey of MINDA’s plastic chain conveyors, detailing the breakthroughs and challenges that redefined intralogistics in the corrugated packaging industry.
When did MINDA start rethinking conveyor technologies?
It was in the late 1990s when multicolor printing gained momentum in the corrugated industry. This technological leap demanded finer corrugated types like E and F flutes due to their smoother surfaces. These materials were excellent for printing but fragile, creating new challenges for transporting stacks.
What made traditional systems unsuitable for these finer materials?
The limitations of roller conveyors and steel chain belts became evident. Rollers often caused a “sheet-walk effect,” disrupting stack alignment. Steel belts, with gaps between strands, could snag and tear sheets.
Additionally, their noise levels were too high for industrial workplaces, and large deflection radii further complicated the logistics. For delicate materials like E-flute, preserving surface integrity was crucial to meet the demands of high-quality printing.
What sparked the move toward plastic chain conveyors?
At the time, plastic chains were primarily used in narrower applications like the food industry. No supplier offered an affordable, industrial-grade solution for wider systems. By 1999, we decided to develop our own. A Dutch customer, recognizing the potential of gentle and precise transportation, agreed to pioneer this innovation in their facility.
How did you overcome the challenges in designing this system?
We started from scratch, tailoring every element—chain modules, sprockets, and slide bases—to meet industrial standards. We focused on minimizing friction, ensuring smooth transport, and maintaining durability. The development of additional components, like transfer cars, shuttles, and turntables, completed the system.
Can you describe the first installation?
Just before 2000, we equipped the Dutch facility with a fully integrated system, including three transfer cars and continuous plastic chain conveyors for intermediate storage. The result was exceptional: gentle handling of fine flutes, higher stacks, and seamless integration across machines.
How was this technology received in the market?
After the success of the first installation, we refined the chain modules and sprocket technology, working closely with suppliers. For example, our unique sprocket design improved chain engagement and durability. These developments, alongside the quieter and smoother operation of plastic chains, won over many customers.
What innovations followed in the years ahead?
One of our milestones was the slide base, which has become an industry standard. Later, we introduced the s-drive system—our next-generation solution that combines 25 years of expertise. It meets modern standards and integrates with auxiliary equipment like the Advector Pre-feeder and Breaker Fractor, ensuring gentle and efficient transport.
What’s unique about your auxiliary components?
We adapted plastic chains for diverse applications, such as rubber-covered chains for feeders and Breaker Fractor belts. Innovations like the Spherical Cross and Spherical Table use integrated balls for fast, smooth corner transfers, eliminating dangerous shear points.
Looking back, what defines MINDA’s success over these 25 years?
Our ability to innovate and adapt. From tackling the limitations of traditional systems to pioneering solutions for modern needs, our journey has always been about delivering excellence in intralogistics.
Thank you so much for the interview.
