Intended Use
The gripper is used to lift and transport cardboard boxes or similar materials that allow suction.
Neutral gases in accordance with EN 983 are approved as evacuation media. Neutral gases in-
clude air, nitrogen and inert gases.
The device may only be used with robot systems that comply with the provisions of DIN IST/TS
15066, DIN EN ISO 10218-1 and DIN EN ISO 10218-2.
Operation as part of a collaborative system is only permitted when the entire system meets the
corresponding legal requirements for collaborative robot systems. The system integrator is re-
sponsible for ensuring that these requirements are complied with.
The possibilities to do this include:
- The use of redundant vacuum/compressed air generation
- The use of battery-operated audio-visual warning devices to monitor the input pressure and
vacuum value
- Safety-oriented vacuum generation and monitoring with a corresponding performance level
The system is mounted on the load suspension provided by the customer using the flanges desig-
nated for this purpose. The customer also provides a control device.
Functional Principle
The system uses vacuum to lift the defined products. The system can be used to lift one or more
cardboard boxes or similar workpieces of various sizes without adapting the suction area to the
specific workpiece.
The system achieves its maximum load-bearing capacity when the complete suction area is en-
gaged with an airtight workpiece with a smooth surface.
The robot system, to which the customer’s system was attached, is responsible for the motion in
the various axes.
When being applied to the workpiece, the foam must be compressed by at least
50%.

1At this pressure, the integrated ejectors have optimal energy efficiency.
2For this gripper version, the compressed air is only used to more quickly deposit loads.
3At a vacuum of –0.15 bar, the vacuum generator must provide the
specified suction flow rate (at the vacuum connection pieces of the FMCB).
4Attention: this refers to real measured values without additional safety
Vacuum in the gripper
For workpieces typical for the application (e.g. cardboard boxes), a vacuum between 250 and
300 mbar is recommended.
A vacuum lower than 200 mbar is not recommended.
The overpressure in the gripper must be limited to a maximum of 0.2 bar.

Items Included in Delivery
For the exact items included in delivery, please refer to the order confirmation.
In addition to the gripper, the following is included in delivery:
4 pcs. M6x12 machine screw according to DIN 7984 for mounting the gripper on the robot
4 pcs. Safety washers to secure against accidental release of the gripper during operation
1 pc Dowel pin Ø 6 mm for exact position locking
1 pc Allen key, size 4, for tightening the screws

Note
The operating instructions are part of the system and must be kept with the system every time it is
relocated.
Mechanical Connection
The system is equipped with a flange connection in accordance with ISO 9409-1-50-4-M6:
The gripper initially comes equipped with a Ø31.5 f7 base in the corresponding robot flange
adapter in order to mount the gripper onto the robot/system.
Afterwards, the position of the gripper can be precisely determined using the included dowel pin if
desired. To do so, position the Ø6H7 bore hole of the gripper flange so that it is congruent with the
Ø6H7 bore hole of the robot flange. Then fix the position by inserting the dowel pin.
Use the included screws and safety washers to mount the gripper on the robot. The required tight-
ening torque can be found in the operating instructions of the robot system.
The system must be attached securely, taking the weight of the system and its maximum load-
bearing capacity into account.

Pneumatic Connection
1. Electrical connection
2. Pneumatic connection
3. Blow-off opening
The compressed air is connected using the plug-in screw union for compressed air hoses, which is
located on the sealing plate and is included in delivery. Requirements for the compressed air pro-
vided by the customer:
Dry, filtered air according to ISO 8573-1:2010 [7:4:4]
Constant operating pressure: 5.5 bar.
If you select a supply hose that is too small, the compressed air supplied to the pneumatic ele-
ments will not be enough for optimal operation.
Compressed air supply
The gripper type FXCB requires 161.5 l/min of compressed air. The compressed air
supply integrated into robots is generally not sufficient.
Ventilation
The openings along the housing of the gripper serve as outlets for the exhaust air
from the ejectors (only FXCB). In order to maintain the gripper’s functionality, these
openings may not be closed or covered.
Vacuum Connection (only FMCB)
1. Hose connection
2. Hose clamp
A hose that is suitable for vacuum applications must be connected at the installed hose connection
and secured with the included hose clamps. The supply hose must have the same nominal diame-
ter as the installed connection. The maximum recommended hose length is around 10 meters.
For instructions on opening the housing, see chapter 8.7 of the complete operating instructions.
Vacuum
Once vacuum is applied in a gripper, it immediately begins suction.

Electrical Connection
The connection for control of the solenoid valve (only FXCB) and the vacuum switch is made using
an 8-pole M12 connector that is integrated into the housing.
The installed valve and the valve switch are switched via PNP.
The plug connectors must not be connected or disconnected when the system is live.
The power supply and signal inputs have a maximum line length of 30 meters.
DANGER
Inappropriate voltage supply
Electric shock, destruction of the electrical components
►
Connection work may only be carried out by a qualified electrical specialist.
►
The system must incorporate safe electrical cut-off of the power supply in compli-
ance with EN60204
►
Do not connect or disconnect the plug connectors when voltage is applied.
►
Only operate the system with protected extra-low voltage.
Observe the corresponding operating instructions when connecting the external
vacuum generator (only FMCB).

state, the gripper is in “Suction” mode.
ATTENTION
Incorrectly connected screw union
Malfunction
►
The multi-pole plug’s screw union must be sealed securely and correctly during
installation of the customer’s cable.

Handling Solution
Optimized control
Only turn on the suction when workpieces are being lifted. Otherwise, additional dust
from the environment is drawn in, which could shorten the necessary maintenance
intervals.

Applying suction
The gripper is placed onto the workpiece being handled.
The sealing plate must be compressed by at least 50% to
ensure that the workpiece is securely gripped.
Only FXCB: The gripper is reset to the “Suction” state by
switching the “Suction OFF” pin (see chapter 5.4). In order
for this to occur, there must be compressed air at the com-
pressed air connection.
Only FMCB: Vacuum is generated externally and must be
present at the vacuum connection. An additional valve for
switching between “Suction ON” and “Suction OFF” is re-
quired.
Once the pre-set vacuum value is reached (green light on
the vacuum switch is on and there is an output signal on
the “Signal output 2” pin – see attached operating instruc-
tions), the gripper may be moved.

FMCB
Setting down
Once the workpiece has been transported and safely set
down on the target surface, it must be deposited.
Only FXCB: Switching on the “Suction OFF” pin ends suc-
tion operation. Optionally, compressed air can be blown in-
to the suction chamber in order to more quickly deposit the
workpiece by switching on the “Vent ON” pin. In order for
this to occur, there must be compressed air at the com-
pressed air connection.
Only FMCB: To deposit the workpiece, the vacuum must
be switched off or disconnected at the vacuum connection.
Optionally, compressed air can be blown into the suction
chamber via the compressed air connection in order to
more quickly deposit the workpiece.
Once the workpiece has been deposited, the gripper must
be returned to a neutral state (Suction OFF and Blow-off
OFF).
