Control bottle infeed before the cartoning station
A cartoner can load reliably only when bottles arrive at the correct pitch, orientation and stability. Product infeed therefore belongs in the machine specification, not as an assumed conveyor connection.
What is product pitch at a cartoning-machine infeed?
Product pitch is the controlled spacing and timing between bottles or bottle groups as they approach the cartoner loading sequence.
Stable pitch allows the machine to assign each product to a carton, collate the correct count and coordinate loading. Irregular pitch can create gaps, collisions or incomplete groups. The infeed design must account for the upstream conveyor, accumulation pressure, bottle friction and the format range.
How are unstable bottles controlled before cartoning?
Unstable bottles are controlled by reducing uncontrolled pressure, supporting the product at appropriate heights, maintaining suitable pitch and using lanes, pockets, lugs or guided transfers where necessary.
The best method depends on the base, centre of gravity, fill movement, closure and label. Excessive side pressure can distort a flexible bottle or mark a label, while insufficient support can allow tipping. Trials should include normal starts, stops and accumulation—not only steady running.
How are pumps, triggers and overhanging closures handled at the cartoner infeed?
Pumps, triggers and overhanging closures are handled by controlling orientation, preventing heads from interlocking and keeping guide or pusher contact away from vulnerable components.
The production condition matters: triggers may need to be locked, pumps may require a defined rotation and closures may project beyond the bottle body. Guides and pockets should reference stable bottle geometry. If orientation cannot be maintained reliably for side loading, controlled top placement may be preferable.
What should the bottle infeed do during starve and block conditions?
During starvation, the infeed should prevent an incomplete group from being committed to a carton; during blockage, it should stop or buffer product without creating damaging pressure or losing product identity.
The exact response must coordinate with upstream and downstream equipment. Define sensor positions, accumulation limits, gap recovery, product memory and what happens to bottles already inside the cartoner. Test both gradual and sudden stops because they can produce different handling behaviour.
The control and restart guide covers the required line states.
Describe the bottle at the point where the cartoner receives it
Send filled bottles, closures, labels, upstream conveyor information and the expected flow so pitch, support, orientation and accumulation can be reviewed.
