Centric Grippers
Versatile 3-finger centric gripper enables eccentrically positioned workpieces to be gripped and centered with consistently high gripping force.
Description
Advantages – Your benefits
- Flexible workpiece handling
Cylindrical workpieces of different sizes can be handled efficiently thanks to the extensively adjustable, freely programmable jaw stroke - High fault tolerance
The drive train ensures reliable centering of the workpiece and a constantly high gripping force even in the event of horizontal positioning errors of the workpiece or robot - Increased efficiency
No start-up distance is required for gripping, which simplifies handling and speeds up the overall process - High robustness
The sealed design with the proven sliding guide makes the gripper resistant to harsh operating conditions - Particularly reliable
The risk of workpiece loss is minimized thanks to the integrated gripping force maintenance with loss detection - High availability
The integrated absolute encoder ensures permanent referencing, even in the event of an emergency stop or power failure - Easy integration
The integration effort is significantly reduced thanks to a wide range of communication interfaces, PLC function blocks and robot plug-ins compatible with leading manufacturers
Options and special information
- Gripping modes
The BasicGrip and StrongGrip gripping modes are available. With BasicGrip continuous operation of the motor and thus permanent re-gripping of the workpiece is possible. The gripping speed is automatically optimized for gripping force adjustment. With StrongGrip, the maximum gripping force is generated and then stored by the gripping force maintenance. Permanent regripping is possible within an adjustable time frame. In addition, defined pause times and maximum ambient temperatures must be taken into account in StrongGrip mode. Further details can be found in the operating manual. - Gripping force maintenance
In the event of an emergency stop or a voltage drop, more than 80% of the originally applied gripping force can be reliably maintained due to a combination of an electric holding brake and the initial tension of the elastic element. If the gripping force and position maintenance is activated preventatively, 100% of the originally applied gripping force can be maintained. Overrun of the gripper fingers when removing the workpiece is a few millimeters and depends on the gripping force generated. Variants without gripping force maintenance are also available as an option. - Seal
The gripper comes strandard with enhanced protection against the ingress of dust or liquids. The IP protection of the electronics is only given if the plug connectors have been mounted properly. The gearbox of the gripper is additionally protected by a seal on the output pinions. - Interface of the base jaws
When the intermediate jaw is used, the interface of the base jaws corresponds to that of the universal gripper PZN-plus. This means that the extensive range of finger accessories for the PZN-plus can also be used for this gripper, taking into account the interfering contours, and the application limits that apply.
