StaubliMPS tool changer400x275Stäubli has announced a newly designed range of compact robotic tool-changing systems, with five new MPS sizes that cover a payload range up to 80 kg. The company said the variety of transfer technologies and precision accuracy (+/- 1.5 µm) give the company robotic tool-changing systems for all payloads and all robots.

“An automatic tool-changing system can significantly increase the productivity of a robot,” the company said in a statement. “For many manufacturing processes, an automatic tool changer is the only way to achieve the high level of individualization that is required across all industries today.” 

The five new systems include the MPS015, MPS025, MPS035, MPS055 and MPS080, covering the entire payload range. The systems are all based on a modular product concept, which results in three efficient solutions for customers. The MPS COMPLETE are pre-configured complete systems ready for immediate use with the shortest delivery time; the MPS MODULAR offers individually assembled customer solutions that are also ready for immediate use and can be delivered on short notice; and MPS CUSTOMIZED systems can be specifically adapted to a customer’s application requirements.

“Our new MPS systems for payloads up to 80 kg offer a comprehensive solution concept,” said Norbert Ermer, business head for robotic tool changers for Stäubli. “From material processing and parts handling, to quality inspection via video, we can transfer just about any technology.”

The company said feed-throughs for pneumatics or vacuums have already been integrated into the locking units of the new systems. For flexible functional expansion, additional modules are available for the transmission of pneumatics and vacuum, for signal and data transmission, or for shielding, grounding, tool coding, and data storage. “The variety of possible technology combinations is thus almost infinite,” said Stäubli.

Stäubli said customers can position the transmission modules very flexibly, adapting them to the robot’s cable package. Using a simple order code, solutions for applications and requirements can be efficiently configured. The robot side of the MPS tool changer includes all the necessary modules to be able to use the tools relevant for the robot. On the tool side, only the transmission modules that are required for the operation of the respective tool are needed, Stäubli said. This makes it possible to operate up to six differently equipped tool sides with one robot side, improving a robot’s ROI.

“Thanks to the extensive and flexible tooling options, we are able to configure optimal solutions for our customers,” said Ermer. “Our diversity of technologies can be easily integrated to completely open up new productivity opportunities for many industries – from electronics and mechanical engineering to metalworking and the plastics industry.”

The company said that for the connection between the robot side and the tool side of the MPS system, they combine cross-shaped guiding surfaces with a spring-loaded ball locking system. This enables systems to achieve maximum precision throughout the entire product life. Tools are always brought back to their 100% exact insertion position, with repeat accuracy at +/- 1.5 µm.

Optionally available status monitoring is integrated directly into the locking unit of the changer system, saving space on the overall height of the coupled changer. Stäubli said this keeps the mass moment of inertia of the tools to the minimum possible, and the robot payload can be used optimally.

Like other Stäubli tool-changing systems (with ranges up to 1530 kg), the new systems are attached directly to the ISO standard flange of every robot, without the need for an adapter. The drilling pattern is also passed on the tool side for assembly. The company also offers a tool stand for all sizes – either independent tool stands or only the tool stand upper part, which can be mounted in standard profile solutions (used for storage). The matching tool hanger modules are mounted on the MPS locking units, the company added.
