A build-up of bottles at a machine’s discharge when downstream flow cannot clear them as required.
Also called: outfeed back-up; bottle build-up; downstream bottle blockage.
Discharge back-up and planned accumulation
No. Accumulation can provide an intentional buffer. A back-up is an outfeed condition where bottles cannot clear as required, rather than simply a group of bottles visible on the conveyor.
Sensor position matters. A discharge build-up is different from the absence of a receiving bottle at the fill point, even if both can stop filling. Locate the signal before interpreting the recorded condition.
Does a back-up sensor identify why downstream flow stopped?
It reports a condition at its sensing point. It does not by itself identify which downstream machine or event caused the build-up. A configured control response is not a complete root-cause diagnosis.
Record the sensor location, bottle condition and line response together. Stop and restart sequences depend on the installed controls.
