Popis
Advantages – Your benefits
- Handling delicate workpieces in a reliable process
by SoftGrip modes with reduced force pulses. - Handle a wide variety of workpieces with just one gripper
by the large range of stroke and continuously adjustable gripping force. - Get started quickly and straightforwardly
by a wide range of communication interfaces and comprehensive support with robot plugins, PLC modules, open-source components, models for virtual commissioning, and the commissioning app in the SCHUNK Control Center. - Suitable for use in highly regulated environments
by cleanroom compatibility, food-compliant lubrication, and low-contamination design. - Reliable gripping along the entire finger length.
The profiled rail guide minimizes gripping force losses and supports high repeat precision. - Avoid workpiece losses
by integrated gripping force maintenance and loss detection. - Selectively bypass interfering contours and speed up gripping processes
by the parallel approach to a freely selectable pre-position even while the machine is in motion. - Continue working immediately after a restart
Without reference run thanks to a high-resolution absolute encoder. - Grip and re-grip workpieces even in the event of positional deviations and tolerances, without requiring an additional approach stroke
by independent centering and the controlled build-up of gripping force via the drive.
Options and special information
- Gripping modes
The BasicGrip and SoftGrip gripping modes are available. With BasicGrip and SoftGrip, continuous operation of the motor and thus permanent re-gripping of the workpiece is possible. The gripping speed is automatically optimized to the gripping force setting with BasicGrip. With SoftGrip, fracture-sensitive workpieces can be gripped particularly gently by reducing the impulse forces to a minimum when they hit the workpiece. - Gripping force maintenance
In the event of an emergency stop or a voltage drop, more than 75% 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, 90% 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 using the intermediate jaw, the interface of the base jaws corresponds to that of the universal gripper PGN-plus-P. This means that the extensive range of finger accessories for the PGN-plus-P can also be used for this gripper, taking into account the interfering contours, and the application limits that apply. - Food-grade lubrication
The product contains food-compliant lubricants as standard. The requirements of standard EN 1672-2:2020 are not fully met. The relevant NSF certificates are available at https://info.nsf.org/USDA/Listings.asp using the lubricant information in the operating manual. Components such as rolling bearings, linear guides, or shock absorbers are not provided with food-compliant lubricants.
