Profinet module with integrated safety technology


11-26-2013 - The Profinet module DL5 from SCHUNK, the competence leader for clamping technology and gripping systems is particularly designed for heavy-duty handling systems of the SWS-L series. Due to its integrated safety technology, the module SIL 2 fulfills the requirements according to IEC 61508, and performance level d according to ISO 13489, and therefore meets the optimum requirements for use in the automotive industry. With an integrated fast startup, Ethernet switch, and 5-digit coded tool identification, it allows fast tool change, and a quick and process-reliable integration into the overall system. In order to avoid a contact fire during the changing process, the power supply contacts of the DL5 are protected with a special electronics (Arc Prevention Circuit). Power, signals, and data are transferred via AIDA-compliant push-pull plug connectors.

The heavy-duty handling systems of the family-owned company are available in sizes 210, 310, 510, and 1210. They are specifically designed for the handling of heavy workpieces and tools. At its four outer surfaces different pneumatic, fluidic, and hydraulic modules, servo and bus modules, welding current modules, coax and fiber optic modules of the robot accessories program from SCHUNK can be attached. The quick-change heads and adapters are pneumatically coupled with each other via a patented self-retaining locking system. Thereby a "no-touch locking system" ensures that the module can be already locked at a distance of 2.5 mm.

ST Robotics Develops the Workspace Sentry for Collaborative Robotics

The ST Robotics Workspace Sentry robot and area safety system are based on a small module that sends an infrared beam across the workspace. If the user puts his hand (or any other object) in the workspace, the robot stops using programmable emergency deceleration. Each module has three beams at different angles and the distance a beam reaches is adjustable. Two or more modules can be daisy chained to watch a wider area. "A robot that is tuned to stop on impact may not be safe. Robots where the trip torque can be set at low thresholds are too slow for any practical industrial application. The best system is where the work area has proximity detectors so the robot stops before impact and that is the approach ST Robotics has taken," states President and CEO of ST Robotics David Sands.
