The area gripping system FMHD can be integrated into systems quickly and efficiently and is equipped with a connection for external vacuum generation. Due to its integrated vacuum reservoir and robust, easy-to-maintain design, this gripper is particularly well suited to performing handling tasks under demanding environmental conditions. In addition, these grippers are ideal for operation with industrial robots and gantries due to their low weight and compact dimensions.
Ideal for highly porous and twisted workpieces
Handling of workpieces from 35 mm width, regardless of geometry, surface and position
Maximum process acceleration and reduced system costs through the use of smaller robots
Up to 70 % reduction in maintenance due to three-part profile design
Sustainable reduction in operating costs through flow optimization

*Values determined in practice when handling a typical workpiece (wooden board with structured surface, gripper fully covered by the workpiece, -0.3 bar system vacuum, without safety factor). They represent orientation values for a rough design. For detailed system design, it is always recommended to carry out suction tests with the original workpiece.
**The external vacuum generator used must provide at least the specified suction volume (at the vacuum connection piece of the FMHD-250) at a vacuum of -0.3 bar.

An existing SBX-C gripper in customer applications can be easily replaced with an FMHD-1R gripper without any changes to the electrical interface or programming. Variants: FMHD ... 1R ... SBPL with directly attached pneumatic vacuum generator FMHD ...1R with hose connection for external vacuum generation The changeover reduces maintenance by up to 70 % and sustainably lowers operating costs. Your local contact will be pleased to provide you with further information.
After switching off the vacuum generation, a residual vacuum remains in the gripper for many workpieces. This can cause the workpieces to stick together, disrupting the process sequence.
To reliably eliminate this residual vacuum, either compressed air for blow-off or atmospheric ventilation can be used.
Atmospheric ventilation offers several advantages:
Typical applications:
The use of impulse valves is particularly recommended when several FMHD vacuum gripper systems are combined in one suction spider.
In the event of a power failure, the cylinders for the vacuum reservoir and vent stay in their last switching position because of the impulse control. This prevents workpieces from falling off by accident and causing process disruptions or damage.
