Robotics in a Split Second: How Modern Grippers Are Transforming Packaging

Whether fragile biscuits, delicate fruit, or sensitive pharmaceutical products, milliseconds can make the difference between quality, efficiency, and waste in today's packaging industry. Companies such as the Schubert Group demonstrate how modern robotics and adaptive grippers are meeting these challenges through finely tuned mechanics, intelligent sensors, and systems that are increasingly capable of "feeling" and "seeing." 

In highly automated packaging lines, processes take place at breathtaking speed: products are sorted, aligned, and packaged, often several hundred times per minute. At the same time, requirements are growing. Consumer goods are becoming increasingly individualized and, in many cases, more delicate. This is particularly evident with products such as biscuits or fresh fruit, where even minimal differences in pressure can result in products that are no longer saleable. 

Different technologies are employed depending on the product. Lightweight baked goods such as biscuits are usually picked up using vacuum suction, while mechanical grippers are primarily used for heavier or more difficult-to-handle products such as cakes or croissants. 

Solutions for these challenges are increasingly being driven by modern robotics. One example is provided by the internationally active Schubert Group, headquartered in Crailsheim, Germany. Founded in 1966 as a manufacturer of packaging machines, the family-owned company is now regarded as a pioneer in the integration of robotic solutions.

Traditional grippers operate according to fixed standards: predefined shapes, specified gripping forces, and limited flexibility. In an increasingly dynamic production environment, however, this is often no longer sufficient. 

Adaptive grippers open up new possibilities. By combining flexible materials with highly precise mechanical components, they can adapt to different shapes, surfaces, and materials. As a result, products can be handled much more gently. At the same time, line flexibility increases significantly, a crucial factor in markets characterized by high product variety. 

Another major innovation lies in the integration of tactile sensors that measure pressure, contact, and resistance while continuously feeding data to the control system. Combined with intelligent algorithms, this creates a form of "haptic intelligence." 

For example, the gripper can determine how sensitive a product is, how much force may be applied, and whether an object has been securely grasped. Adjustments are made almost in real time, reducing product damage and enabling higher throughput rates. 

In addition to "feeling," the ability to "see" is becoming increasingly important. Modern 3D vision systems capture products in real time, even when they are randomly positioned on a conveyor belt. 

The combination of image processing and sensor technology enables precise identification of product position and orientation, dynamic adjustment of gripping points, and reliable operation even when product shapes vary. 

This interplay of multiple data sources is considered a key building block of modern packaging robotics. Companies such as Schubert integrate these technologies directly into their packaging machines with the aim of creating fully integrated systems. Typical applications include delicate confectionery and baked goods, fresh foods with variable shapes, and pharmaceutical products with stringent safety requirements. 

As promising as these technological advances may be, implementing them in practice remains challenging. Adaptive gripping systems must integrate seamlessly into existing production lines, process large volumes of data in real time, and remain economically scalable. 

At the same time, the demand for qualified specialists continues to grow, both in system development and in daily operations. 

Nevertheless, the pace of innovation remains high, driven by artificial intelligence, enhanced sensor technologies, and increasingly capable self-learning systems. Future robotic solutions will be able to adapt even more independently to new products and production requirements, ultimately leading to fully adaptive packaging lines. 

Companies such as Schubert are already working on such concepts today and view them as a key lever for the future of the industry.
