Schmalz offers the FMG matrix gripper, a sophisticated surface gripper for the automated handling of various workpieces in manufacturing and logistics processes. This allows users to adapt more easily to processes and machines.
Schmalz has developed the FMG matrix area gripper, an innovative solution for the automated handling of flat and predominantly airtight workpieces. Its key feature: thanks to its modular design, the FMG can grip almost any geometry. Users can easily expand or reduce the gripper's size as needed by adding further modules. The gripper modules, each with twelve suction points, weigh less than one kilogram and can be connected in any configuration. Schmalz creates a specific flange plate for the desired arrangement, to which the FMG modules are attached. Optional proximity switches further enhance process reliability.
The suction cups can be individually and selectively activated with compressed air. This extends the suction points by ten millimeters via a plunger. Simultaneously, this opens a channel that directs the external vacuum to the workpiece. This ensures that only the suction cups necessary for gripping the workpiece geometry make contact. This prevents the suction of incorrect parts. When the valve is switched off, the spring return retracts the suction point, thus deactivating it.

Leaks at inactive suction points are eliminated. The integrated air-saving control ensures low energy consumption while guaranteeing a constant vacuum supply. The system secures the workpiece with its auto-hold function, even in the event of a power failure. Thanks to the standardized suction cup interface, users can utilize various vacuum suction cups with diameters from 12 to 28 mm.
A higher-level machine control system or a camera sensor provides the data on gripping points to activate the suction cups according to the geometry and position of the workpieces. Alternatively, Schmalz offers a complete system including a camera and software for product recognition and gripping point calculation. Thanks to simultaneous control, the system can be set up for new items in less than a second.
The area gripper requires an external vacuum supply. The compact terminal SCTSi is a suitable option, centrally controlling the gripping system and capable of controlling up to eight FMG modules via IO-Link. Each unit's individual ejector discs supply the system with the required 50 liters of suction capacity per minute. The integrated air-saving function reduces compressed air consumption by up to 80 percent.
