Robot tool changing systems

Andreas Mühlbauer,

Further optimizing production lines

Automated processes have long been a decisive aspect in almost every industry in terms of increasing efficiency and quality. In order to further optimize industrial production lines, Stäubli focuses on the development of innovative tool changing systems for robots and offers configurable and individual solutions for all payload ranges.

Stäubli Fluid Connectors is committed to providing the industry with unrivaled connectivity solutions that not only keep workers safe, but also reduce energy consumption and CO2 emissions and support highly efficient industrial processes. By integrating a tool changing system from Stäubli, the degree of automation and flexibility of existing robot systems can be significantly increased: Downtimes are reduced and operating times optimized thanks to conceivably simple and fast tool changes, which leads to an overall increase in production efficiency. At the same time, thanks to the high-quality changing systems from Stäubli, which are manufactured entirely in-house, including all components, production steps are carried out much more precisely, which in turn has an impact on the quality of the end products.

Sustainability that pays off

Innovation and sustainability are part of Stäubli's DNA and ensure maximum efficiency in equal measure. The more durable a tool changing system is, for example, the better its ecological and economic balance. However, as companies must always remain technically up-to-date at the same time, Stäubli Fluid Connectors offers a perfect way forward with the high flexibility of its solutions: all systems can be adapted to new conditions at any time as part of a retooling or retrofit. In this way, durable solutions can actually achieve a long service life.

Contemporary solutions for maximum flexibility

The increasing demand for customization and the resulting continuous increase in the diversity of product segments also pose major challenges for production processes. High-quality and reliable quick-change systems play an even more decisive role. For the greatest possible multifunctionality and versatility, Stäubli therefore offers all robot tool changing systems as part of a modular concept in which customers can choose between configurable standard modules from the existing product portfolio and completely customized solutions.

Numerous configuration options

In order to meet the respective application requirements, numerous modules are available for the transmission of signals, data, pneumatics, vacuum, shielding, earthing, tool coding and data storage. Thanks to the ability to flexibly position all transmission modules, they can be precisely adapted to the robot's cable package.

Another advantage of the modular systems: Since only transfer modules that are required for the operation of the respective tool are installed on the tool side, any number of tool sides can be operated with just one maximum equipped robot side. This results in an optimum ROI. The individually configured changers are supplied fully assembled and ready for use and can be adapted or extended for new applications at a later date.

Compact small payload models

For the low payload range up to 55 kg, the four models MPS 015, MPS 025, MPS 035 and MPS 055 are a series of compact robot tool changing systems with integrated media feed-throughs and optional data and energy transfer modules. In addition, each system offers integrated functions for pneumatics and vacuum, which are already integrated into the locking units. The small payload solutions from Stäubli Fluid Connectors are thus characterized by a wide range of transmission technologies and an extremely high repeat accuracy of +/-0.0015 mm.

The perfect middle ground: Medium payload systems up to 350 kg

Their weight-optimized design is the decisive advantage of the MPS 080, MPS 130 and MPS 260 tool changing systems. The series for medium payload requirements enables users to avoid having to invest in robots of the next higher payload class and is thus designed for a wide range of applications in all possible industrial sectors. This series is also based on the Stäubli claim of being able to configure customized solutions as simply as possible. Despite their optimized dead weight, the medium payload models can be equipped with various modules for the transmission of media, data and electrical energy according to the respective customer requirements and meet the latest ISO standard in terms of safety requirements with Performance Level d, Category 3.

High performance in the high payload range

Manufacturing processes with high payloads of up to 2.5 tons, such as spot welding, require a correspondingly high level of user-friendliness and reliability when changing tools. With its MPS 631, MPS 1531 and MPS 2531 high payload systems, Stäubli meets precisely these requirements and offers precise solutions that meet the highest safety standards.

Specially designed for applications with diverse production technologies, the round design of the three large tool changing systems from Stäubli enables the assembly of a large number of transfer modules. At the same time, thanks to their compact design and flexible module positioning, work areas that would be inaccessible with other systems can be accessed even in confined spaces. This highly effective use of space can be further intensified by the use of compact and flexible storage stations, enabling the integration of an optimized cell or line setup.

Just like the systems for light and medium payloads, the high payload models are also based on the internationally proven modular product concept of the Stäubli robot tool changing systems: High-precision base units ensure the secure connection of robot and tool, while the transfer modules, which can be flexibly positioned on the base units, ensure highly efficient media transfer.
