| What is included | Air conveyor, roller conveyor, depalletizer, palletizer |
| Function | Move bottles and cases without damage, stack outbound pallets |
| Key control | Accumulation pressure, guide rail gap, pattern repeatability |
| Types | Semi-automatic and automatic palletizing |
| Key decision | Manual, semi-automatic or robotic palletizing |
| Automation | Manual, semi-automatic or robotic |
Automatic palletizing pays when the labour it replaces is continuous and the pattern is stable. A plant running two shifts at high case rates reaches payback faster than a single-shift plant with mixed patterns, because a robot needs the pattern defined before it can be programmed.
Enough to cover the longest normal stop downstream without stopping the filler, and no more. Extra accumulation hides a problem instead of solving it, and it adds floor space plus a place for bottles to sit and collect dust. The buffer size is a calculation, not a default.
| Function | Manual | Automatic |
|---|---|---|
| Depalletizing empty bottles | Rack or hand stack | Layer depalletizer |
| Case palletizing | Operator with pattern sheet | Layer or robotic palletizer |
| Pallet wrapping | Hand wrapper | In-line stretch wrapper |
| Accumulation | None, line stops together | Buffer sized to longest stop |
The unit behind this configuration is the Conveying.
Floor loading for a full pallet stack, clear height for the mast or robot envelope, and a pallet dispenser within reach of the operator. These are building decisions taken before the machine is ordered, and changing them later costs more than the palletizer.
Reference unit for this duty: the Depalletizing & Palletizing.
Enough to cover the longest normal downstream stop without stopping the filler. Beyond that, accumulation only hides the problem and adds floor space. The number comes from the stop-time log, not from a rule of thumb.
The same question is worked through from another angle in The Role of Depalletizers in High-Speed Bottling Lines.
A guide rail gap set for a different diameter, a transfer plate at the wrong height, or too much back pressure behind the jam. All three are mechanical settings and all three drift when a second format is introduced.
It is rated in cases or layers per hour and must exceed the packer output with margin. The number to compare is the pattern-adjusted rate, not the headline figure at one layer size.
Guide rail gap and transfer plate height. Both are set for one bottle diameter and both drift when a second format is introduced. Re-set them at every changeover, not once at installation.
A robot is more flexible across patterns and gentler on the pack; a layer palletizer is faster for a single stable pattern. The choice follows the pattern mix, not the technology.
Low air pressure, a worn layer clamp, or a pallet that is not square. Empty bottle layers are light, so small errors become fallen bottles at the infeed.
When the pattern is stable and the labour is available at the end of the line. It costs less and runs slower, and it needs an operator for every layer change.
