*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.

Can a gripper from the previous SBX-C series be replaced by an FMHD gripper?

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.

What advantages does the variant with atmospheric ventilation offer compared to blow-off with compressed air and for which applications is it suitable?

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:

  • Shorter set-down times: It enables the fastest workpiece release, especially with longer grippers. Compared to compressed air blow-off, the set-down time can be reduced by approx. 50 %.
  • Cost efficiency: Virtually no compressed air is required, which reduces compressed air consumption and lowers ongoing operating costs.

Typical applications:

  • Handling of sawn timber, glued wood, planed and panel goods, construction timber, pallets and crate elements
  • Handling of naturally grown material with knotholes, cracks and heavily twisted and rough surfaces
  • Ideal for use in sawmills, wood and furniture construction companies
When does it make sense to use impulse valves for area grippers?

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.
