Area Gripping Systems FMHD

Robust gripping system with integrated reservoir for external vacuum generation

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.

Application

Handling of naturally grown material with knotholes, cracks and heavily twisted, rough surfaces
Ideal for the rough application conditions in sawmills or in woodworking and furniture construction
Can be used for unstacking and handling workpieces in layers
Outstanding holding force
Ideal for highly porous and twisted workpieces
Unique flexibility
Handling of workpieces from 35 mm width, regardless of geometry, surface and position
Low weight
Maximum process acceleration and reduced system costs through the use of smaller robots
Minimal maintenance effort
Up to 70 % reduction in maintenance due to three-part profile design
High energy efficiency
Sustainable reduction in operating costs through flow optimization
  • Aluminum basic profile (1) with integrated vacuum storage for high rigidity with low dead weight

*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.
