Air Springs in Packaging Equipment Grippers

As flexible actuating and cushioning elements, air springs are integrated into packaging equipment grippers to solve the challenges of handling fragile items and products with widely varying specifications.

Key Advantages

Flexible Adaptability: The inflatable bladder conforms to the contour of the workpiece—gripping cartons without damaging edges, handling soft pouches without tearing, and holding bottles securely without slipping.
Constant-Force Clamping: Clamping force is determined by air pressure, so switching between product specifications requires only a pressure adjustment rather than a mechanical component change, enabling rapid changeovers.
Cushioning and Protection: The system absorbs impact generated during the downward motion and closing of the gripper, acting as a "soft limit" during overloads to protect both the workpiece and the gripper itself.
Floating Alignment: The elastic deformation of the bladder automatically compensates for minor positional deviations, reducing the need for high-precision positioning and minimizing the risk of jamming or scratching.

Typical Applications

Case packing for soft pouches and stand-up pouches
Handling glass bottles and condiment containers
Carton forming and loading
Picking and placing produce or baked goods
Packaging lines for powders and granules

Offering flexibility, constant force, cushioning, and adaptability, these air springs serve as an effective complement to rigid mechanical grippers and vacuum suction cups—ideally suited for automated processes involving diverse product specifications, fragile items, or soft packaging.
