| Scope | 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.
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.
| 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 |
Reference unit for this duty: the Depalletizing & Palletizing.
When the pattern mix is wide and the pack is fragile. A layer palletizer is faster on one stable pattern; a robot changes pattern by program. Most plants with more than three patterns choose the robot for that reason alone.
Throughput and change-part lists are on the Conveying page rather than in this note.
Square pallets, consistent layer sheets and a stable stack. Empty bottles are light, so a leaning pallet becomes a fallen layer at the depalletizer. The machine can only work with the stack it is given.
The same question is worked through from another angle in How Palletizers Improve Bottling Line Workflow.
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.
A depalletizer unloads empty bottles or full cases from a pallet at the start of a line. A palletizer stacks finished cases onto a pallet at the end. They are separate machines with separate footprints.
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.
It follows the filler rate with margin for accumulation, not the maximum the conveyor can carry. Running a conveyor faster than the line needs increases scuffing and jam severity.
