Test Line at Bosch-Siemens Dish Washing Machine Factory | |
| Bosch-Siemens Hausgeräte at Dillingen in Germany is the biggest and most modern dish washing machine factory in Europe. The factory has more than 2500 employees. Approximately 6,500 machines are produced each day. The machines are marketed as several different makes. Each machine passes a severe quality control test. A total of 8 test lines each with 35 testing stands is used. 3 of these testing lines are now controlled by P-NET equipment. The machines change position every 40 seconds throughout the testing line, and are then removed at the starting point. The mounting and testing of the machines is performed in a continuous flow. Each machine is connected to water, drain, power and test equipment. The test is a combination of a visual inspection and an automatic function and performance test. The design and installation of the entire automatic testing system was performed by Ultrakust. |
 |
| Each testing stand has its own measuring station, which performs the testing, measuring and data logging. The identity of each machine is read by means of a barcode reader, and stored with the test results. The P-NET module which performs the testing is equipped with a graphic data screen. The test results can be seen on the screen as function of time. Errors during testing are diagnosed and displayed. P-NET controllers are used as gateways, and for managing the P-NET interconnections. The P-NET communication is performed via infrared transceivers. PC's collect data for test reports and for quality management. The assembly and the internal handling of the machines is computer controlled, and the trucks, which deliver the raw materials, are routed via a radio link. |
