A new technological leap for the packaging industry

With its cobots, the packaging machine manufacturer is once again proving why it does not simply adopt technologies, but rather develops them into ground-breaking innovations for the industry. In fact, the first cobots are already being tested by customers for the automation of infeed processes. The use of image processing with underlying artificial intelligence makes the new cooperative robots from Schubert extremely flexible and exceptionally easy to program.

Before developing a new technology, innovation driver Schubert first analyses the processes and business models that are most likely to influence the packaging industry in the future. This is why robotics have played a pivotal role in the company for over 40 years. Now the packaging machine manufacturer has a new milestone in sight with its cobot, called ‘tog’. For the first time ever, Schubert cobots automate simple manual processes outside of the highly efficient machine sequences and can be adapted to new tasks very quickly without requiring any programming knowledge. Ralf Schubert, Managing Partner of Gerhard Schubert GmbH, describes the rationale: “We developed the tog.519 for pick & place applications with lightweight products, where previous cobots would be out of their depth.” The tog simplifies and accelerates packaging processes even further: “With one of our cobots, manufacturers will be able to react much more flexibly in the future to changing market situations and requirements,” explains Schubert.

The Schubert cobot has one of the world's fastest capabilities for ‘gripping from disorder’.

Key advantages: fast and extremely user-friendly

A high working speed and remarkably simple operation are essential to deliver this extraordinary flexibility. Ralf Schubert asserts, “Our cobot has one of the world’s fastest capabilities for ‘gripping from disorder’.” To ensure speed throughout, it makes sense to use a protective cell when space is limited. However, the Cobot also offers the ability to operate without a protective cell while maintaining a high level of safety. When operating as a free-standing robot, the Schubert cobot does not work directly together with humans (collaborative). But it does work in an environment with them. Such cobots are referred to as cooperative or coexistent and call for a very different safety concept. “To achieve this, we used image processing to actually teach the cobot how to see,” adds the Managing Partner. “This way, when approached by employees, it gradually reduces its speed until it comes to a complete standstill.” It is only through the vision system that the fast cycle rate is possible when reaching into disorder or for the simple adaptation to new tasks. Schubert highlights, “The interface-free combination of robotics and vision is a very important feature of our tog series.”

For the first time ever, the new cobots automate simple manual processes outside of highly efficient machine sequences and can be very quickly adapted to new tasks.

Artificial intelligence as a technology driver

The prerequisites here are provided by a neural network with artificial intelligence (AI) developed in-house by Schubert, which precisely matches specific industry requirements in terms of safety, speed and programming. This is absolutely unique in this area of application. To program a specific product, the network is trained using product photos in the Schubert Cloud and then loaded onto the cobot as a format. To reliably recognise new products, the AI only needs a handful of images and three days’ time. “We are making the learning process so simple that our customers will be able to create new formats and products themselves in the future without having any prior knowledge of image processing or programming,” confirms Ralf Schubert. Via the HD camera system integrated into the cobot, the AI then decides how the cobot should proceed. The tog.519 – the first Schubert cobot – is currently being tested by a customer.

A modular system from schubert

The Schubert cobots are being developed by a new division within the company. An entire family of cobots will follow in the coming years. A complete modular system for cobot solutions has been defined as the goal, comprising five-axis Scara kinematics, a vision system, infeed belts, format parts and much more. Key areas of application are in the food sector, as well as in cosmetics and pharmaceuticals. In other words, wherever lightweight products have to be fed very quickly into a system. High volumes can also be processed in kit assembly, where different products need to be combined into a single kit, or in product finishing. The Schubert cobots will soon offer automation possibilities within the packaging industry which no other cobot can achieve today.

Schubert selected the winners of the painting contest together with the Regio-Business magazine. The children received their awards from Marius Stephan, Regio-Business, as well as Ralf Schubert, Franziska Schubert and Carolin Dierolf (all from Schubert).

Painting contest: Winning kids are honoured at Schubert

Last year, Schubert joined forces with the Hohenloher Tagblatt newspaper to organise a painting contest for kids. Young artists between the ages of 6 and 12 had an opportunity to put their creative ideas to paper on the subject of “What will the packaging of the future look like?” or “How can packaging waste be avoided?” At the end of December, all the winning children were invited to spend an exciting afternoon at the company’s premises.
