Batch size one realised
The designed solution is convincing.The Bürkle team automated more than a dozen different work processes in very close cooperation with Riwag. The centralised data provision takes place in the work preparation department.The doors run through all production stages with this data. In the spray coating line, a barcode scanner reads the data into the system. All details, including how the sanding process has to take place, which colour is used, where the spray coating nozzle starts and how quickly the painted door runs through the UV drying process, are taken into account. One-off quantities are realised throughout. The doors are automatically measured, coated and sorted and stacked after painting.
Significantly reduced reject rate
The system operates in a "stop and go" mode with corresponding waiting positions before and after the processing machines. The cycle operation ensures that necessary process steps can be completed and that processing steps on workpieces are not interrupted during a process, resulting in rejects. This approach ensures very good surface quality and improves cost-effectiveness, as the reject rate is close to zero.
Result of good co-operation
The entire system is fully connected to the Riwag production control system. The machine parameter data of all components of the spray painting system are continuously exchanged with the control system. Bürkle realised this complex connection with in-house software experts. "In order to implement the data connection as smoothly as possible, very extensive data processing and preparation was necessary on both sides even before the actual order was placed," explains Martin Brümmerstädt, Bürkle's process engineering expert for the spray coating sector. This resulted in a deep and cooperative relationship of trust between the companies involved even before the order was placed, which contributed significantly to the excellent solution.
Changes possible at short notice
With the new spray coaiting line at Riwag, it is even possible to change the door colour up to two minutes before the barcode is scanned. The overall quality of the system and the good cooperation with a single partner who was able to offer everything from a single source were convincing.
"We are very satisfied. I still don't know anything about synchronised swimming. I have learnt to appreciate the Bürkle spray coating technology very much in the meantime," Albisser concludes.
