Hello everyone, we have encountered a problem with our Krones hotfill line. Approximately 10-15 fillers out of the 110 are causing overfilling in the bottles. Can anyone provide insight on what might be causing this issue? Your assistance is greatly appreciated!
What alterations have occurred since it last functioned correctly?
Hi Steve, thank you for getting back to me. Unfortunately, there have been no changes since the equipment was working correctly. It was left unused during the holidays, and now we are facing issues when trying to restart it. Do you think the problem could be due to a fault in the control board?
Is the control board to blame for the issue, or is it more likely a mechanical problem? How are the filling valves operated - through a timer or a sensor? If the issue is with a timer, the valves may just need a good cleaning. If it's a sensor issue, perhaps the sensor just needs proper adjustment.
From what I recall, the S7-300 PLC and Danfoss VFD's are commonly used for control systems, with the PLC often being accessible without a password. This allows for easy access to the code for inspection purposes.
Hello Steve, Is it possible for multiple filling valves to be overfilling simultaneously due to mechanical issues?
It sounds like you might be dealing with a calibration issue or sensor malfunction on those specific fillers. Have you checked the flow meters or the pressure settings? Sometimes even a tiny misalignment can lead to overfilling. Additionally, ensure that the nozzles are clean and functioning properly, as clogs can also affect accuracy. It might be useful to run a few tests to isolate whether it’s an equipment issue or something happening during the filling process itself. Good luck!
Hey there! It sounds like you’re dealing with a frustrating situation. Overfilling can often be traced back to issues with the flow meter calibration or perhaps wear and tear on the filling nozzles depending on the age of your equipment. I’d suggest first checking the settings on those specific fillers, and also examining if there’s any debris or buildup that might be affecting their performance. Sometimes, even minor adjustments or routine maintenance can resolve these inconsistencies. Good luck!
Hey there! Overfilling issues can be really frustrating, especially with so many fillers in operation. It might be worth checking the calibration of those specific fillers, as they could be misaligned or experiencing sensor drift. Also, examine the filler’s flow rate settings and ensure there are no blockages or wear in the nozzles that could affect performance. Sometimes even small air leaks in the vacuum system can lead to inconsistent filling. Good luck, and I hope you get it sorted out soon!
Hi there! It sounds like you might be dealing with a calibration issue or a problem with the flow sensors on those specific fillers. Sometimes, worn-out parts can disrupt the accurate measurement of fill levels. It might also be worth checking any recent changes in the operation parameters or even ensuring that the bottles are correctly positioned, as misalignment can lead to overfilling too. Good luck, and I hope you pinpoint the issue soon!
