Staubli’s MPS 630 automatic tool-changing system for robot arms can handle tools up to 630kg and withstand the high bending and torsional moments created by fast-moving robots.

All the services required by the tool are simultaneously connected and the electric or pneumatically activated locking mechanism ensures failsafe security.

The facility to automatically change the tool employed on a robot arm from, for example, a welding gun to a rivet gun or gripper, is said to increase the utilisation of each robot arm and can often eliminate the need for investment in additional robots.

Additional operations usually require additional robots; but with the facility to quickly and automatically change the tools on a robot arm, the need for a second or even third robot is eliminated, reducing the capital investment required, improving payback and often reducing the overall cell footprint.

The MPS 630 is the latest addition to the range of high-performance tool-changing systems available from Staubli, which now extends from 32kg up to 630kg tool-weight capability.

The MPS 630 is designed to handle tools up to 630kg and the locking mechanism can accommodate the high moments (up to 5,000Nm) that fast-moving, high-payload robots can place on the tool-holding equipment.

The connectors will withstand the pulsating pressures caused by self-piercing guns and metal-clinching tools.

It is directly mountable onto the robot flange and requires little mounting space, according to Staubli.

Retention of the tool on the robot arm is ensured by a new design of locking mechanism, which can be either pneumatically or electrically actuated.

Both systems provide high security and failsafe locking, with the design using a series of locking balls to connect across a large diameter.

The electric version is specifically designed for applications where the systems installed in a robot cell need to be minimised, such as in the nuclear sector.

All the systems required by the tools are connected automatically, employing the connection-guiding and clean-break technology used in Staubli multi-coupling plates.

Fluid lines (for example, compressed air, gases and liquids); signal and data transfer connections such as those required for actuators, sensors, bus systems or fibre optics and energy connections (for example, electricity and hydraulics) are automatically connected to the tool and disconnected without any loss of fluid or ingress of air into the circuits.

Consumables such as bolts or rivets can also be automatically connected and fed through to the tool.

The modular design means that the tool changer can be configured with precisely the type of connectors required for each specific application.

Multi-Contact (MC), Staubli’s sister company in the connectors division, contributed to the design of the tool changer.

MC has designed an array of electrical connectors for both power and signals; housed in one unit and incorporating its multilam technology.

The electrical connector units are modular in design, allowing the connector array to be replaced without any rewiring or need to disturb the main cables.

Wear and pitting of the cable connections can often affect welding and the ability to rapidly replace is an advantage.

The replacement module connects to the main cabling using MC’s multilam technology, ensuring an effective connection.

Tool changers can be supplied separately or as part of a complete system including docking stations, with the option of tool-cooling circuits or in-built safety systems.

Advancements in productivity and operational flexibility can be achieved using automated tool/gripper changers by minimising robot downtime and ensuring correct connection of all services.

The level of capital investment required on additional robots is reduced too, by fully utilising all of the capabilities of the installed equipment.

Typical applications include riveting, resistance spot welding, stud welding, metal clinching and self-piercing joining techniques in the automotive sector, as well as material handling, gluing and metal-transfer requirements across a wide spread of industry.
