EMS installations for gear-box assembly at ZF
The gear-box assembly at ZF in Friedrichshafen in optimal, ergonomic position due to the EMS automotives with three movement axes.
For a EMS-oval with an approximate length of 50 m there are necessary 13 vehicles for the continuous transport of the two different gear types (Ecomat and Ecolife) with a mounting speed of 0,47 m/min. Thereby the vehicles pass through 13 working stations from the reception of the empty gearboxes until the hand-over of the completely assembled transmission units. The positioning of the vehicle is performed with a barcode band along the EHB track and a barcode reader from the vehicle. In order to allow for the operators to work in an optimal-ergonomic location, the vehicle must be equipped with a spindle lift drive and an additional rotary drive which brings automatically the gearbox in the desired position after each process.
