4 Product overview

4.1 Function

–

Alternating pressurisation of the supply ports causes a piston in the gripper to

move (double-acting).

–

A gripper with integrated spring return is used to exert the gripper force. When

exhausting the single-acting gripper: the spring return moves the gripper jaws

to the initial position.

–N/O contact: NO (normally open)

–N/C contact: NC (normally closed)

–

The piston movement is transmitted mechanically to the gripper jaws. Gripper

fingers are fastened to the gripper jaws. Closing or opening the gripper fingers

clamps the payload to the outer contour (external gripping) or the inner contour

(internal gripping).

–

The gripping force is adjusted by external regulation of the operating pressure.

–The gripper has integrated fixed flow restrictors. If the max. gripper finger

weights and the max. gripper finger lengths are in compliance, an external flow

control is not required.

Requirements for the gripper fingers

11 Technical data:

–

Observe the max. permissible forces and max. permissible torques at the

gripper jaw.

–Observe the max. length and max. weight.

–

Use gripper fingers that are as short and light as possible.

–

Manufacture gripper fingers that are suitable for the payload and type of grip-

ping action.

Mounting gripper

If necessary, mount the proximity switches before mounting the gripper.

When using proximity switches for sensing the end position, take the following

into account:

• Interference from ferritic attachments, e.g. retaining screws made of ferritic

steel.

• Projecting proximity switches, if applicable.

• Cable outlet direction of the proximity switches.

• Sufficient space for the connection components.

• When sensing from both end positions: use separate slots for the proximity

switches.

Installation

6.1 Pneumatic installation

NOTICE

Loss of function due to contamination in the connections.

• Keep ports and tubing lines free from dirt particles and foreign matter.

The use of a check valve prevents the payload from dropping in the event of

a sudden pressure drop. The use of a one-way flow control valve also permits

adjustment of the opening and closing time.
