End-of-Line Automation
Palletizers and depalletizers handle the transition between individual containers or packs and full pallets. These machines operate at the boundaries of the bottling line and significantly impact warehouse logistics and labour requirements.
Palletizer Types Comparison
| Type | Speed | Flexibility | Maintenance |
|---|---|---|---|
| Low-level conventional | 40–80 layers/hr | Limited | Moderate — mechanical |
| High-level conventional | 60–120+ layers/hr | Limited | Moderate — mechanical |
| Robotic articulated arm | Variable | Very high | Servo drives, grippers |
| Gantry/cartesian | 40–100 layers/hr | High | Linear guides, servos |
Conventional Palletizer Inspection
- Layer forming chain condition and elongation
- Sweep bar mechanism wear and timing
- Elevator platform level accuracy
- Pallet dispenser reliability
- Slip sheet/tier sheet applicator if equipped
- Safety fence and interlock condition
Robotic Palletizer Assessment
- Robot arm joint play and cable wear
- Gripper mechanism condition
- Programme library completeness for all pallet patterns
- Teach pendant functionality
- Safety scanner and area detection system
- Cycle time verification at rated speed
Depalletizer Considerations
Depalletizers handle incoming empty containers — glass bottles or empty cans from the supplier. Key inspection points include sweep head condition, layer pad removal system, and bottle handling gentleness. Rough handling causes micro-cracks in glass bottles.
Frequently asked questions
When should I choose a robotic palletizer?
Robotic palletizers are ideal when you have multiple product formats requiring frequent pattern changes. For single-format high-speed lines, conventional palletizers remain more efficient.
How much does a used palletizer cost?
Conventional palletizers range from €20,000–€80,000. Robotic palletizers range from €40,000–€150,000. Price depends on speed, condition, and included peripherals.
Can a palletizer handle different pallet sizes?
Most palletizers accommodate standard EUR (800x1200mm) and US (1000x1200mm) pallets. Some models handle both with minor adjustment. Verify compatibility with your specific pallet dimensions.
