Powerful robot coupling for pallet handling
16.04.2012 -
If machine tools are loaded automatically, a reliable, precise, and space saving workpiece
change is playing an important role. For this particular case, SCHUNK, the competence
leader for clamping technology and gripping systems has developed a slim, lightweight
coupling with minimized interfering contours, where the pallet loading is taking place very
close to the machine table. By using the VERO-S NSR, very thin attachments to the clamping
station and pallet are feasible, and therefore a lot of space remains for the workpiece in
the machine room, and for the axes motions.
A lightweight handles up to 350 kg
At a weight of 1.6 kg (size 160), the robot coupling achieves pull-down forces of up to 15
kN, and is an extremely rigid system. It transfers torques of up to 1600 Nm, and is also
suitable for reliable handling of heavy pallets of up 350 kg (with dimensions of 400 x 400
mm). Every quick-change pallet system of the family-owned company is equipped with a
double angle clamping stroke, and therefore allows such high weights. In order to
achieve an optimal relationship between rigidity, robustness, and weight, the SCHUNK
engineers have designed every part that does not transmit force in aluminum, and parts
that do transmit force in hardened stainless steel. The module’s locking is self-locking
and uses form-fit clamping. At a pneumatic system pressure of 6 bar the module can
be unlocked, without needing lubrified air. Opening, closing, and pallet presence are
monitored via inductive proximity switches, and therefore the whole changing process
can be monitored, too. Moreover, the module with a high compact performance is com-
pletely sealed and thus protected against chips and coolant.
