Go big! Gripping Systems for Big Tasks
The Quick-Change Pallet System fixes the components
SCHUNK also continually uses the VERO-S Quick-Change Pallet System for heavy-laod gripping systems. Normally this system is used for high-precision workpiece change in machine tools. The basis of the clamping system is the pneumatically actuated clamping module made of stainless steel. They are the mountings for one or several clamping pins, which can be screwed directly into the heavy-load components, into the clamping unit, or laterally into the clamping pallets. Via a radially arranged clamping slide in the quick-change pallet module, the pins are pulled in and locked. Locking is done mechanically via a spring package which is self-locking and clamps form-fit. Thereby pull-down forces up to 40,000 N and holding forces up to 75,000 N are achieved, and can hold heavy, moving components absolutely safely. In contrast to other quick-change pallet systems, the spring-packaged VERO-S needs no compressed air during handling. The workpieces remain safely clamped in case of a sudden pressure drop in the air system. In order to unlock the clamping module, a system pressure of 6 bar is enough, as it is available for every compressor unit.
A fast tool change is guaranteed
For ensuring a fast gripper and tool change even for heavy-load applications, SCHUNK has standardized a changing system for heavy-load robots. The SWS-L-1210 is designed for payloads of up 1,200 kg. It disposes of three locking systems and absorbs the statical moments of up to 5,400 N in all three axis. The locking mode of the changer can be monitored via integrated sensors. Moreover, three so-called "ready to lock" sensors are integrated in the changing head. As soon as all three sensors report that the changing head is less than 1.5 mm away from the adapter, changing head and adapter are coupled.
For easy assembly at the robot arm the changer is equipped with the hole pattern for ISO flanges with 200 and 250 millimeter in diameter. Since the screw-on surface of the SWS-L-510 to SWS-L-1210 quick-change systems are compatible, users can fall back to numerous SCHUNK components even for heavy-load applications: among others pneumatic-, fluid- and hydraulic modules, servo-and bus modules, welding current modules, as well as koax- and light conductor modules.
Sophisticated accessories allow economic heavy-load handling
For Matthias Poguntke of SCHUNK it is obvious that heavy-load robots will become more important. "Gripping systems and accessories play an important role, if robots should be used economically. Therefore SCHUNK continously enlarges its modular program and its competence for special solutions in the field of heavy-load applications", said Poguntke. A high degree of modularity, a consistant light-weight design and the courage to develop new solutions even for difficult challenges should ensure that the user can fully make the most of the potentials of modern heavy-load handling.
