As a leading expert for clamping technology and gripping systems, SCHUNK has long been known for its rapid pick&place units. Now the innovative family-owned company has added the pneumatic DRL 025 stroke/rotary unit as an additional pace maker to its range of modular high performance assemblies. The rotary loader enables highly dynamic and steady pick&place operations with rotating angles of either 90° or 180° for the assembly of electronics, medical technology and consumer goods.
The movement of the vertical cylinder and the rotary drive is positively driven by a cam roller, which allows both units to be switched earlier, which significantly reduces the cycle time in comparison to conventional stroke/rotary units. This enables up to 90 cycles per minute at minimal loads and a rotating angle of 180° (additional switching and gripping times). To additionally increase system productivity and process stability, the versatile control can be used to stop the effector directly over its target position and enter the standby position until the feed or the depositing unit is ready. At an operating pressure of 5 bar, the stroke/rotary unit achieves a torque of 3.7 Nm and a piston force of 320 N. The vertical stroke is 40 mm, with 20 mm of that being linear. In order to compensate for tolerances and system-dependent deviations in the collection and deposition positions, the rotating angle can be adjusted by +/- 2°, and the vertical stroke can be adjusted by up to 10 mm per side. The compact unit is designed for mass moments of inertia up to 0.03 kgm2. In the 180° version, it can fully replace linear pick&place units in which the parts must be turned 180° using a rotary module. As part of SCHUNK'S modular high-performance assembly systems, which offers the world's largest selection, the DRL 025 can be combined with ease and versatility with a variety of gripping, rotary and linear modules to create complete functional units or assembly groups.
