Compact Welding Cell with Additional Axes
Reis GmbH & Co. KG Maschinenfabrik, Obernburg, Germany, offers a "plug-and-play" welding cell with high-capacity RobotStarV controller and two freely programmable additional axes. The cell, which is designed to ensure economical robot welding even for small series, consists of an upright or suspended, six-axis Reis RV10-6 vertical articulated arm robot. The RV10-6 has a payload capacity of 6 kg and a repeatability of 0.05 mm and is designed for complex path tasks. Thanks to its rigid construction and enclosed drive elements, it can be operated in extreme conditions.
The robot and rotary table are mounted on a common transport frame. Also mounted on the transport frame is the entire (closed) safety cabin. The manual rotary table is equipped with two additional tailstock turning devices, with a separation between tips of 1,200 mm and a payload of 100 kg. These can be separately controlled and deployed as seventh and eighth external robot axes in order to optimally position components relative to the robot.
While the robot is welding workpieces in one station, finished parts can be unloaded at the other and new parts be loaded. The cell can also be arranged for welding different components in alternating stations. Integrated synchronization of the table position with reference to the robot even allows different programs to be processed on alternate sides. This creates greater flexibility.
A special bearing enables the workpiece carrier plate to be easily moved, and thus minimizes strain on the operator. With this rotary table concept, complicated and expensive safety equipment becomes redundant - light barriers, step mats, swing doors and two-hand operations can be eliminated. Since euro pallets and boxes with single or finished components can be stored right beside the rotary table within reach of the operator, resulting downtimes are reduced to a minimum.
