When is a Pull Back Unit recommended? - Bagger
Product Information Pull Back Unit (PBU) Svalehøjvej 10 DK-3650 Ølstykke Tlf.: +45 7020 7633 Fax: +45 7020 7603 www.bagger-nielsen.dk [email protected] Challenge When the robot reaches its minimum or maximum range of motion, the excess length of the Robotrax cable carrier either strikes the robot arm or experiences crushing / kinking. Design Goal • Actively pull back excess carrier length caused by large range of motion as well as high accelerations. • Safely guide cables in pull back unit. • Increase cable carrier service life. • Allow for easy system assembly. • Insert and replace cables and hoses without disconnecting the carrier. • Ensure pull back force to be adjustable. • Design universal system for all Robotrax sizes. • Develop low-maintenance or maintenance-free system.

If cables are to be guided in the ROBOTRAX application in a defined movement. To increase service life for Robotrax cable carrier and cables. If cables are to be inserted without disconnecting the carrier from the robot. To ensure easy cable replacement. If pull back force needs to be adjustable. To prevent Robotrax cable carrier from crushing/kinking and to protect it from striking against parts of the robot. When is a Pull Back Unit not recommended If Robotrax cable carrier does not have excess length. • If installation space is limited (check available space at the robot arm and during robotic movement). • If weight of pull back unit is too high for robot system. • Most important features at a glance • • • • • Pulling the Robotrax cable carrier out of the enclosure (Pull Back Unit) and retracting it back safely and constantly adjust carrier length, as needed, during robotic movement. Increased service life of the Robotrax system and drastically reduced downtime for repair caused by excessive wear. Rigid and torsion-free enclosure may be mounted directly to the robot arm as an option. To safely guide the cables in the Pull Back Unit, a short UNIFLEX Advanced-series cable carrier traveling inside the enclosure is attached to the end of the 3D flexible cable carrier. Inside the Pull Back Unit the cables are guided in a defined movement without dropping below the minimum bend radius.
