Robotic Arc Welding installation with seam tracking and tilted column
AAF required a solution to automate the welding of large hoppers. These hoppers needed to be welded both internally and externally and therefore a solution was required that could reach practically any point on a part requiring welding and that also enabled automatic rotation of the hoppers. Until then, AAF welded and rotated parts manually. The standard gantry solution did not facilitate access to all necessary welding points.
The solution is based on a welding cell with two work stations enabling welding in one or the other independently, while in the second station the operator may load and unload the part.
This cell is also composed of a longitudinal track with an effective run of 10,600 mm and an tilted column to elevate the robot to different heights while being able to approach the part and the different welding points, both internal and externally.
Additionally, 2 positioners in each work station enable full rotation of the hopper.
The solution provided by Yaskawa facilitates increased production cycles by reducing handling and welding times due to the two independent work stations, offering a more technically suited system with greater reach than the gantry solution.
Using the solution provided by YASKAWA, AAF has achieved a reduction in welding time from 4h to 1h per unit.
Furthermore, AAF is currently using the installation for the welding of other parts even larger than the initial hoppers.
Yaskawa extends MotoLogix software interface
Robot programming now with EtherCAT connection
The software interface MotoLogix enables Yaskawa Motoman robots to be quickly and easily programmed and controlled via PLC in the standard IEC-61131 environment. Now Yaskawa has broadened the spectrum of supported platforms to include the EtherCAT standard. Above and beyond EtherCAT, integrated solutions on the basis of POWERLINK, EtherNet/IP and PROFINET are still possible with MotoLogix. Robots can thus be programmed and controlled with controllers from Siemens, Beckhoff, B&R, Rockwell – and, of course, Yaskawa.
After integration into the PLC all genuine advantages of robot control are retained. The robot controller calculates the movement kinematics and ensures high quality of movement. This means that Yaskawa know-how when it comes to exact motion sequences of the manipulators is still guaranteed. This is where the strong points of these robots and respective controllers come to the fore, particularly in all forms of handling, such as machine loading, picking, packaging, placing, palletizing or measuring, testing and sorting.
The simple integration of the robot controller into the PLC pays off not only in the operation of complex production systems. The choice of MotoLogix means that PLC expertise will suffice for the control of robots. It is no longer necessary to search for personnel trained in robotics or to spend money on retraining staff. Yaskawa robots can thus be operated worldwide under the same conditions.
