In the realm of automated manufacturing, the efficiency of robotic systems hinges on the integrity of their cable management. Tsubaki Kabelschlepp has introduced the Robotrax System, a sophisticated three-dimensional cable carrier specifically engineered to address the challenges posed by dynamic robotic movements.
Addressing Mechanical Stress
Modern industrial robots, particularly six-axis articulated models, are tasked with executing high-speed, multidirectional maneuvers. However, the cables, fiber optics, and pneumatic hoses that power these robots often face severe mechanical stress during operation. Such stress can lead to premature conductor fatigue and insulation breakdown, resulting in costly production interruptions.
Central Steel Technology
The Robotrax System distinguishes itself through its innovative use of a central steel cable that runs through each chain link. This design absorbs the primary tensile loads experienced during rapid directional shifts and accelerations of up to 10 g, effectively isolating the electrical and fluid lines from damaging pulling forces. This mechanism significantly extends the service life of cables and hoses, ensuring their reliability over prolonged operational cycles.
Modular Design for Flexibility
At the heart of the Robotrax System is its open, single-piece plastic link design, which features spherical snap-on connections. This allows for smooth flexing across three axes, accommodating radial rotation of up to ±450 degrees per meter, depending on the model. The carrier links can house up to three distinct chambers, preventing signal interference and mechanical abrasion between different types of cables. For standard models, installation is tool-free, streamlining maintenance processes.
Active Retraction and Impact Protection
To further enhance performance, Tsubaki Kabelschlepp has integrated the Pull Back Unit (PBU), an active retraction mechanism that maintains optimal tension on the cable carrier throughout its motion cycle. This feature minimizes the risk of collisions between the cable carrier and the robot body, a common issue in environments with large work envelopes and high-speed trajectories. The PBU is designed for zero maintenance and is compatible with major industrial robot platforms such as KUKA, ABB, and FANUC.
With additional protective accessories like heat shields and strain relief devices, the Robotrax System is built to withstand the rigors of demanding industrial environments. By combining advanced load absorption, multi-axis flexibility, and active retraction control, this system offers a reliable solution for maximizing robot uptime and minimizing operational costs.
