Automated component transport in industrial applications is one of the main growth fields for assistance robotics. Where components and samples are painstakingly moved by hand today, robot-assisted logistics solutions of the future will supply parts around the clock in versatile, traceable and highly efficient processes.
The pace of development for assistance robots in intralogistics is highly dynamic. While just a few years ago only prototypical methods existed, today there are already numerous standardized solutions that have withstood the test of time in practical use. SCHUNK, the competence leader for clamping technology and gripping systems is a technology driver in this field. The central handling component is the versatile and powerful SCHUNK LWA Powerball lightweight arm, one of the most powerful lightweight arms in the world. Its excellent repeat accuracy of +/-0,15 mm ensures high process stability. Also, a cleverly thought-out design prevents dangerous crushing and shearing movements. Since the supply lines for the gripper and tools are completely within the module, there are no interference-prone cables on the peripheral devices. Consistent lightweight construction and state-of-the-art torque motors keep the energy demands of the lightweight arm down to an average of 80 W.
For mobile use as linear axis or shuttle
The 24V concept allows battery-powered operation of the SCHUNK Powerball lightweight arm in mobile applications. Linear motor driven axes of the SCHUNK LDx series provide for versatile and dynamic processes along one axis. They eliminate time-consuming reference runs during system startup and emergency stops. In addition, the modules require neither end nor reference sensors, therefore reducing the investment costs, programming requirements and the number of cables in the cable set. Since several freely programmable slides with SCHUNK lightweight arms can be placed on one guide profile, SCHUNK LDx modules can be used to achieve especially compact and cost effective concepts. SCHUNK LDL, LDN, LDM or LDT linear modules serve as the basis. With a maximum nominal stroke of up to 3,800 mm, maximum acceleration of 40 ms-2, maximum velocity of 4 ms-1 and a maximum load capacity of up to 50 kg they can be used in a wide range of applications. As standard equipment these modules feature Bosch Rexroth IndraDrive controllers; a Siemens SINAMICS S120 converter is also possible as an option. SCHUNK offers all LDx modules with the standard interfaces Profibus, Sercos III, Profinet IO, EtherNet/IP and EtherCat for fast and easy integration in higher level system controllers.
For more complex transport tasks, such as between different systems, intermediate stores or areas, shuttle systems such as autonomous transport robots from SERVUS ROBOTICS are the right choice. They can likewise be equipped with SCHUNK lightweight arms and can travel to the single stations via a rail system, independently of each other and just-in-time. The entire system is easily scalable and can therefore be adapted quickly and easily to different production processes. It can be used to control the entire in-plant material flow, from goods receipt through an automated warehouse, production, assembly and picking all the way to shipping. With lifting systems it is even possible to implement multi-level solutions. The system is therefore ideal for the versatile and efficient automation of in-plant transport systems, supermarket strategies and kanban systems.
