| Supply 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.
Empty bottle layers are light and unstable, so the depalletizer is where a badly stacked pallet becomes a line stop. Layer pickup, sweep speed and the interface with the air conveyor are the three settings to check, and the pallet quality from the bottle supplier matters as much as the machine.
| 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 Depalletizing & Palletizing.
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.
Site requirements, air and power consumption sit with the Conveying.
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.
The same question is worked through from another angle in How to Optimize Conveyor Systems in Water Filling Lines.
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.
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.
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.
