GIMATIC GRIPPING SYSTEMS

Gimatic FGS-60 foam vacuum gripping systems (60mm),FGS-120 foam vacuum gripping systems (120mm), FGS-120-SC vacuum cup gripping systems (120mm), and the Foam Gripper with Carbon Fiber Body are all equipped with an integrated vacuum generator and are available with self-closing valves or with calibrated holes.

The integrated vacuum generator consists of EJ-LARGE-HF-3 multistage ejectors. These ejectors have high suction capacity, low energy consumption, no moving mechanical parts, and do not generate heat.

• Available with foam or with VG.IS polyurethane suction cups.


• Foam gripper width is either 60mm or 120mm, and available in multiple lengths: 200mm, 400mm, 600mm, 800mm, 1000mm, and 1200mm. Custom sizes available, contact EMI.


• Available in different hole pitches as required.

TYPICAL APPLICATIONS:

Palletizing and handling applications in different industries. Ideal for handling cardboard boxes, wooden panels, cans and many other products with different formats and shapes.

FOAM FEATURES:

• Material: EPDM
• Thickness: 20mm
• Temperature range: -40°F — 275°F (-40°C — 135°C)
• Fine pitch oval (A) for objects with a minimum width of 35mm.
• Medium pitch round (B) for objects with a minimum width of 55mm.
• Easy to install and remove with no residue on the extruded piece.

LIFTING FORCE: Theoretical gripping force on flat surface, with fully covered gripping surface, safety factor (N) excluded.

SUCTION CUP FEATURES:

• Material: Polyurethane (PU)
• Temperature range: 32°F — 122°F (0°C — 50°C)
• Available sizes: 35mm cup: VG.IS35 (A), and 55mm cup: VG.IS55 (B).
• The VG.IS polyurethane suction cups ensure high wear resistance and adaptability to uneven and porous surfaces.

LIFTING FORCE: Theoretical gripping force on flat surface, with fully covered gripping surface, safety factor (N) excluded.

OPERATING PRINCIPLE FOR SELF CLOSING VALVES:

How it works: The vacuum channel has a chamber containing a metal ball. In the absence of the object to be picked up, the metal ball moves and hermetically closes the vacuum channel.

When to use it: Ideal in different applications and formats, where a high level of vacuum must be maintained, despite the fact that most of the surface of the manipulator may not be gripping.

Strengths: Faster, more flexible, less sensitive to dust, with lower consumption as it requires smaller pumps.

1. Positioning of the gripping system on the object to be handled, parallel to the gripping surface.
2. Approaching of the gripping system until contact is made with the gripping surface.
3. Activation of vacuum generation.
4. Picking up of the object to be handled.
5. Deposit of the object with vacuum deactivation and blow-off if necessary.

OPERATING PRINCIPLE FOR CALIBRATED HOLES:

How it works: The vacuum channel has a bottleneck (calibrated microhole), which generates a known leak in the vacuum chamber if the object to be picked up is missing.

When to use it: Ideal when self-closing valves cannot be used (e.g. in vertical handling applications) or when the gripping system covers about 90% of the gripping surface to be handled.

Strengths: Can also work at 180°, lightweight.

1. Positioning of the gripping system on the object to be handled, parallel to the gripping surface.
2. Approaching of the gripping system until contact is made with the gripping surface. Vacuum activation before contact with the object is advised for high-speed applications.
3. Picking up of the object to be handled.
4. Deposit of the object with vacuum deactivation and blow-off if necessary.
