Schunk pneumatic DRL 025 loading system assists high speed assembly
1 min read
Schunk's DRK 025 stroke/rotary loading system is intended for electronics, medical and consumer goods assembly applications. It enables highly dynamic and steady pick and place operations with rotating angles of either 90° or 180°. The movement of the vertical cylinder and the rotary drive roller are both positively cam driven which allows them to be switched earlier resulting in fast cycle times. Up to 90 cycles per minute at minimal loads with a rotating angle of 180° (additional switching and gripping times) can be achieved, says Schunk.
The versatile control can be used to stop the DRL 025 directly over its target and enter the standby position until the feed or the depositing unit is ready. At an operating pressure of 5 bar, the stroke/rotary system 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. 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, the DRL can fully replace linear pick and place units where parts must be turned 180° using a rotary module. The DRL 025 can be combined with a variety of Schunk gripping, rotary and linear modules.
