PET Bottle Conveyor Jams: Locate the First Unstable Transfer,"The largest pile-up is often downstream of the first disturbance. Follow bottles through consecutive transfers and locate where upright, evenly spaced flow first becomes unstable. Compare like operating states: empty bottles, filled bottles and restart accumulation load behave differently.",
Jams begin at a transfer,"Record transfer geometry, bottle orientation and speed states on both sides. Compare guide continuity and support surfaces under the approved isolated inspection procedure.",
Jams follow an upstream stop,"Time the downstream blockage, upstream stop and restart sequence. Compare buffer occupancy and release behavior rather than only increasing conveyor speed.",
Only one bottle format jams,"Retain bottle drawings, actual dimensions and change-part identifiers. Check the approved format setup and bottle stability with the responsible machine supplier.",
Evidence to send with a support request,"Send a safe observation video, transfer location sketch, bottle format, empty or full state, line speed, accumulation state and first-event timestamps. Record the initiating event separately from the resulting blockage so downtime is not attributed to the wrong machine.",
Illustrative diagnostic comparison,"If bottles first tilt at one transfer and a queue builds farther downstream, treat the tilt point as the investigation location. Clearing the visible queue without reproducing the transfer condition does not demonstrate that the cause has been corrected.",
"Record the bottle, cap and material lot; machine and format recipe; time, speed and operating state. Separate direct observations from suspected causes. Preserve an unchanged comparison and identify who approved any trial.","Record the bottle, cap and material lot; machine and format recipe; time, speed and operating state.

Confirm the next action,"Record the approved change, comparable before-and-after observations, defect counts with their denominators, and quality or maintenance approval. A symptom disappearing once does not establish a durable correction.",
Confirm the next action,Repeat the check during the operating state that originally produced the defect. Keep restart losses and rejected product in the record; a faster machine reading alone is not proof of improvement.,
"Use approved site procedures and the machine manual. Isolate energy before physical inspection or clearing a jam; never bypass guards or interlocks. Quality personnel decide containment and release of affected product. These guides do not prescribe universal pressure, temperature, torque or cleaning settings.","Use approved site procedures and the machine manual.
