High-speed for press lines
Schuler Crossbar Feeder
Göppingen - With the launch of its new Crossbar Feeder, Schuler has raised the productivity of stamping plants of the future. With this newly developed, high-speed automation device, Schuler has applied crossbar technology to the problem of linking individual mechanical and hydraulic presses. Similar to the part transfer of a compact crossbar transfer press, the part is passed in a single action from one die to the next and – where necessary – re-positioned. The Crossbar Feeder can be freely programmed in seven different axes – ensuring high flexibility. Output can also be raised significantly in comparison to conventional lines with robot or feeder linkage. While robot and feeder linkage can reach speeds of up to ten and eleven strokes per minute, respectively, the new Crossbar Feeder boasts up to 13 strokes per minute. This high output level also helps reduce part-specific manufacturing costs.
Easily retrofitted boost to output
The Crossbar Feeder can be retrofitted to existing mechanical and hydraulic press lines, without having to make adjustments to the presses, dies or sliding bolsters. By taking the corresponding modernization measures, the output and flexibility of standard press lines can be improved considerably.The Crossbar Feeder moves along a longitudinal crossbar fixed by holder brackets to the press uprights. By adjusting this crossbar, the new feeder can be adapted for use with varying press spacing. As the Crossbar Feeder is not led along the side of the press uprights, but hangs between the slides on longitudinal and traversing crossbars, the upright width does not need to be adjusted when retrofitting.
More safety, less space
Due to its compact design, new press lines already supplied with the Crossbar Feeder can be positioned more closely together. The new feeder also enables smaller upright widths. This serves to optimize press rigidity and minimize space requirements. A further consequence: the shorter Crossbar is extremely stiff and thus guarantees improved transport reliability. The absence of an intermediate station also reduces the space requirements of the press. At the same time, the new design allows unrestricted access to the die space and the Crossbar Feeder itself, for example during maintenance.PC-based control and visualization
The system is controlled by Schuler’s newly developed, PC-based control and visualization concept. The new concept enables easier operation as well as the evaluation of SPS and NC programs and data, so that malfunctions can be identified and rectified more swiftly. The new system also shortens planning and production launch phases – resulting in shorter overall lead times. Predefined movement curves can be easily adjusted or completely revised during subsequent operation. This guarantees perfect and flexible adjustment to the die and part – also for the future.
