Direct answer
Find the first point where control is lost. A downstream alarm is often only the final symptom of poor feeding, transfer, detection or format control. For sachets, confirm the result with representative product and packaging before altering several variables at once.
Likely causes
- Product orientation or spacing is unstable in the sachets process.
- A transfer gap, guide or sensor allows control to be lost in the sachets process.
- Material or dimensional variation exceeds the setup in the sachets process.
- The line restarts before the downstream condition is clear in the sachets process.
What should be checked first?
- Record the first abnormal event on video
- Inspect the fault from above and from the side
- Measure transfer height, gap and guide position
- Check product and pack variation
- Review sensor alignment and response
- Test at low and full rate
- Verify blocked and restart logic
What should you compare before buying?
Compare the operating principle against the actual product, pack range, sustained good output, measurable quality limits, cleaning, changeover and site conditions. Use representative samples and agree what will be demonstrated during testing before delivery and after installation.
