Coval’s improved vacuum grippers with comms interface

Coval offers manufacturers a range of vacuum grippers suitable for handling of parts of various sizes, weights, and materials. This gripper range has been extended with the latest CMS HD series multistage vacuum pumps, developed by Coval.

Coval ‘s range of vacuum grippers is based on two complementary solutions. The CVGL is characterised by its lightness and great adaptability. It is available as standard in several lengths, power ratings, and gripping interfaces. The MVG offers the possibility of configuring the gripper to allow it to be adapted to each application by determining the length, width, gripping interface, and vacuum generator while offering extreme lightness. A tailored solution can integrate with handling robots.

Coval’s new generation of vacuum grippers now incorporate the latest CMS HD series of vacuum pumps. These pumps have a heavy-duty design for high reliability even in harsh environments (IP65), capable of ensuring 50 million cycles. A factor of the pump´s longevity is their modular design, which allows specific configurations and targeted maintenance of specific parts to optimise repairability. As a result, the new generation of CMS HD multistage pumps adds to the vacuum grippers´ reliability and adaptability.

The new Coval vacuum grippers offer a choice of three multistage vacuum pump configurations, depending on the needs of the integrator or end user: non-piloted, piloted, and communicating. The communicating configuration, which makes the vacuum grippers easier to use and parameterize, is obtained by integrating the CMS HD VX version of the multistage pump.

The VX pump version features an IO-Link communication interface, compliant with the international IEC 61131-9 standard, for fast and cost-effective installation, continuous diagnostics, centralised parameterisation and efficient communication with higher-level protocols (EtherNet/IP, PROFINET, EtherCAT, etc.). It can also support a human machine interface (HMI) with NFC interface, enabling the operator to read and modify setup parameters and diagnostics from a mobile device (Android or iOS) using the dedicated Coval Vacuum Manager app.

With these pump capabilities, the new generation of COVAL vacuum grippers become even more versatile and compatible with the robot systems at the heart of Industry 4.0.  A Due to their great modularity and ease of integration in all contexts, CVGL and MVG vacuum grippers can be found in many industries: packaging, plastic, metal, and wood for handling porous and non-porous objects.
