Fast pallet change

Now of up to 1,000 kg

09-16-2013 - The compact SCHUNK robot couplings VERO-S NSR continue to set standards at high-efficiency, robot-supported pallet change on machine tools: with the module VERO-S NSR maxi 220 the system is becoming even in the heavyweight class a superior favorite for pallet handling. It transfers torques up to 4,000 Nm, and can reliably handle up to 1,000 kg (at 800 x 800 mm). Due to the developed locking system with patented strokes (fast and clamping stroke) from SCHUNK, such large masses can be handled. Locking is done form-fit, and is self-retaining. All the components of the powerhouse are made of hardened, stainless steel. In order to ensure a process-reliable function in challenging environments, it is completely sealed against chips and coolant. Moreover, a standardized cleaning function ensures a chip-free surface contact between pallet and robot coupling. For process monitoring, locking and unlocking conditions are monitored via a position sensor, and the presence of pallet via an inductive proximity switch. Repeat accuracy amounts to 0.02 mm.

Upgrade of the modules up to 350 kg

The innovative family-owned company also completes the VERO-S NSR sizes with smaller and medium-sized sizes: in order to achieve maximum process stability, these standard modules are also equipped with a cleaning function now. Steel inlays at the contact areas make the robot couplings extremely wear-resistant. Despite the upgrade, the module weight remains unchanged. Due to the consequent lightweight design, the modules with optimized interfering contours weigh 400 g (NSR mini 100), 1,600 g (NSR 160). They are suitable for reliable handling of pallets up to 75 kg (at 200 x 200 mm), or up to 350 kg (at 400 x 400 mm). Together in a team with the new heavy-duty module NSR maxi 220, they are covering the complete range from 1 to 1,000 kg.

New KUKA Robot: KR 3 AGILUS Maximum performance in minimum space

Great advances often start with small steps - in manufacturing cells measuring only 600 × 600 mm. Here, the KR 3 AGILUS is in its element. Particularly in the case of small parts and products which must be produced in a minimum of space. KUKA expertise, concentrated into the smallest of spaces, is setting new standards for the 3-kg class. The lightweight robot masters various tasks with agility, dynamism and maximum precision, leading to high flexibility in production - even when it comes to extremely narrow spaces.
