Product Inquiry

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.

 

  • Aluminum basic profile (1) with integrated vacuum storage for high rigidity with low dead weight
  • Hose connection and separating cylinder (2); connection of external vacuum generators
  • End cover (3) with control valves for separating cylinder and blow-off function
  • Valve profile (4) with integrated missile valves
  • Optional third row of suction holes enables handling of narrow workpieces from 35 mm width in sawmill environment

Especially easy to service

The foldable quick-change suction plate permits quick and easy maintenance of the gripper. In addition, a compact cylinder unit, a new clip-on valve film, and the quick-change foam enable highly optimized maintenance procedures.


Suction plate with a width of 250 mm for increased load

More holding power

Outstanding holding force for heavily porous and twisted workpieces thanks to integrated vacuum reservoir

Minimal maintenance work

Maintenance cost reduced by up to 70% through three-piece profile design

Unique flexibility

Handling of workpieces from 35 mm width, regardless of geometry, surface and position

High energy efficiency

Sustainable reduction of operating costs through flow optimization and more efficient use of energy

Low weight

Maximum acceleration within the process and reduced system costs through use of smaller robots

Integration of functions

High functional safety and minimized installation costs due to integrated vacuum and depositing valve

*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.
