PSSG sack gripper: Lightweight with a long service life

Bulk goods and liquids can be packaged in bags to save resources and costs. Depending on the content, shrink wrapped goods made of paper, plastics or textile fabrics are used. The new PSSG sack gripper from Schmalz handles different bags efficiently and reliably. It is lightweight and therefore ideal for collaborative applications. Another advantage: the flyweight made of fibreglass-reinforced plastic enables short cycle times and thus increases the overall performance and productivity of the robot.

The new sealing lip made of FDA-compliant silicone or wear-resistant NBR (acrylonitrile butadiene rubber) ensures a long service life. Depending on the application, specialists only need to replace these components after twice the service life of conventional foam rubber seals. This means that maintenance intervals are significantly longer and the handling process is more stable. An NFC chip in the main body communicates with the Schmalz app via a mobile device. This allows specialists to conveniently trigger a spare parts order and watch a video on how to change the sealing lip. Schmalz does not bond the sealing but uses a metal insert for the connection, which is screwed to the main body. This means it only takes a few minutes to replace the seal. Thanks to the sustainable concept, the materials can be easily separated and recycled individually during disposal.

The PSSG moves porous, bag-like workpieces as well as suction-tight bags - even with a low fill level. This means that companies can dispense with gripper changes and can pick, palletize and depalletize more efficiently. The end effector is compatible with all common lightweight robots and has a maximum suction area of 405 × 305 millimetres with a load capacity of up to 50 kilograms.
