Stäubli's new line extends robot range

Stäubli’s new TS2 line of four-axis SCARA robots provides improved flexibility for production line tasks compared with the company’s TS line, which it is replacing.

A TS2-60 four-axis SCARA robot, configured for a ceiling mountStäubli Corp.The four new robots, with reaches ranging from 18.1 inches to 39.3 inches, have a maximum payload of 18.5 pounds.

Stäubli said that robots in the line have a fully enclosed design with all cables routed internally through the arm, a compact footprint and ultra-short cycle times with a high degree of repeatability. The robots feature a completely sealed housing and can be modified to work in food packaging, medical products and pharmaceutical packaging applications. An ESD-compliant version is available for the electronics industry.

TS2 robots can also be equipped with integrated, automated tool-changing systems. This allows the robot to replace its grippers and tools automatically.

The robots come with cables already installed inside the arm to accommodate vision systems.

Other features include Stäubli’s patented JCS gearbox drive on arm joints 1 and 2; modern, 19-bit multi-turn digital encoders that are safety rated; and pneumatic and electrical connections at the tool. Versions that mount on the floor and ceiling are available. The JCS technology has already improved the performance and versatility of Stäubli’s six-axis robots, the company said.

TS2 models have high dexterity in small workspaces because of the compact integration of the motors, the company said. This also means multiple robots can be used in a cramped space. All four models have a 7.9-inch stroke with an option to increase the stroke to 15.7 inches.

“The TS2 has new mechanics inside the arm, and there are no blind spots,” a Stäubli spokesman said.

The line’s four models are the TS2-40, TS2-60, TS2-80 and TS2-100. The numbers in the model names represent their approximate reach in millimeters. All use Stäubli’s CS9 controller, which also controls the company’s six-axis robots.

All the TS2 machines have the same robot pedestal that Stäubli uses for the TX2 series. Forearms, axes and drives are also identical to the TX2 on many models. Stäubli said this reduces delivery time for new robots and saves costs.

In addition to other performance improvements over the TS line, the TS2 series has a working radius of up to 39 inches, compared with 31 inches for the TS series.

In addition to the new robot series, Stäubli has added new tool-changing systems:

• MPS Complete is a preconfigured, ready-to-install tool changer for common applications. Stäubli can quickly deliver these tool changers, which have a modular design that facilitates easy replacement of parts or upgrades.

 • MPS Modular is for applications where the changer needs to be individually configured. The tool changer can be put together from a modular assembly kit and can be reconfigured for different tasks.

• MPS Customized is an option for customers who need a tailored solution assembled by Stäubli technicians.

Tool-storage stations are available.

“Tool changers greatly improve the versatility of robots, which makes them even more effective and more easily adaptable to changing manufacturing scenarios,” said Roger Varin, CEO of Stäubli North America, in a press release. “We are continually pushing to introduce innovations that allow for automated solutions.”

Another Stäubli product that improves robots’ versatility is the new Multi-Coupling System (MCS). The system combines multiple service connection points into one assembly. A custom-made MCS can accommodate connections for pneumatics, liquids, gases, hydraulics and electricity.

Varis said using an MCS quick connector improves the functionality and efficiency of robots and improves safety during installation. The risk of incorrectly connecting wires is eliminated.
