Feeding and presentation
The machine has to convert bulk or semi-bulk containers into an orderly flow that downstream equipment can accept consistently.
Empty bottle handling
Empty bottle handling guide
Empty bottles behave differently from filled bottles. They are lighter, less stable and more affected by friction, air movement and guide settings.
Specification advice
What this means for the bottle infeed section.
Accumulation and control
Enough buffer is needed to stop downstream equipment starving, but too much pressure can create jams or mark bottles.
Line integration
The feeder, conveyor, transfer and downstream machine should be specified as one handling system rather than separate items.
Practical checks
Use the bottle and line data to reduce quote guesswork.
The best enquiry includes real bottle information, the target line speed and details of the downstream equipment. This gives the supplier enough information to recommend a sensible machine route instead of guessing from a catalogue picture.
For urgent projects, send bottle photos, sample dimensions, output target, conveyor height and a short description of the current line problem.

Questions
Common questions before choosing a bottle infeed route.
Why are empty bottles harder to feed?
They are lighter and less stable than filled bottles, so small guide or speed changes can have a large effect.
What equipment handles empty bottles?
Options include rotary feed tables, automatic unscramblers, conveyors and integrated infeed systems.
Should bottle samples be tested?
Yes. Real bottles give the best indication of feeding stability and transfer behaviour.
