At our most recent trade fair, aaa Berlin, visitors were able to experience a special vacuum gripper live in action. In the accompanying video, my colleague presents the application in a practical and clearly understandable way. It demonstrates how intuitive and, at the same time, how safe the operation of the gripper is – particularly when handling glass panels.
Vacuum Grippers for Smooth, Airtight Surface Elements
Vacuum grippers are among the most proven load handling devices in manual handling technology when it comes to smooth and airtight components. Typical applications can be found, for example, in the automotive industry, where large-format glass panels or similar parts must be picked up precisely, handled without damage and moved ergonomically.
The operating principle is based on generating a vacuum between the suction cups and the workpiece. This creates a force-locked connection that enables secure gripping and controlled movement of the load – without mechanical clamping or localised stress on the component.
High Safety Through Intelligent Monitoring Systems
The gripper shown is equipped with continuous vacuum monitoring. This system permanently monitors the vacuum level in the suction cups and ensures that the required holding force is available at all times.
In addition, load monitoring provides maximum safety:Unintentional dropping of the glass panel while suspended is structurally prevented. Releasing the load is only possible when the gripper is unloaded – for example, after the glass panel has been safely set down. This reliably prevents hazardous situations for the operator and the surrounding environment.
Redundancy Through Two Vacuum Circuits
A key safety feature is the dual-circuit system. The gripper is equipped with two independent vacuum circuits, each operating with multiple suction cups. As few as two suction cups per circuit are sufficient to ensure safe load handling.
The circuits operate together; however, if one circuit fails, the second circuit continues to maintain the holding function. Lifting is no longer possible only if both vacuum circuits are interrupted. If the gripper is already in a lifted position at that moment, the load can be lowered in a controlled manner. Otherwise, the gripper automatically and slowly lowers itself, providing an additional level of safety.
Flexibility and Ergonomic Operation
The gripper allows a 90° rotation, which is particularly important when switching between horizontal and vertical orientations of glass panels – for example, during installation into vehicle bodies or frames.
Releasing and rotating the load is conveniently performed at the push of a button, ensuring a simple, repeatable and safe operating process.
Another key advantage:The operator can guide the gripper directly on the workpiece, i.e. on the glass panel itself. This direct guidance enables highly precise positioning, improves control of the movement and significantly reduces physical strain.
Advantages of Vacuum Grippers in Manual Handling
In summary, vacuum grippers offer numerous advantages when handling glass panels and similar surface elements:
safe and damage-free gripping of smooth components
high process reliability through vacuum and load monitoring
ergonomic operation and reduced physical strain for the operator
flexible movements, including rotation functions
redundant safety systems through multiple vacuum circuitsintuitive operation and precise load guidance
Applications like this clearly demonstrate how vacuum grippers successfully combine safety, ergonomics and process stability. Especially when handling sensitive yet heavy surface elements such as glass panels – or even cartons – well-designed monitoring and safety concepts are essential for reliable operation.
The solution presented highlights the potential of modern manual handling technology when it is consistently aligned with the requirements of both operators and processes – from secure load gripping and controlled movement through to precise positioning of the component.
