View of a pallet exchanger with a diagram of the whole system.The pallet exchanger is a unit composed of a pneumatic depalletizer and a lift table with chain conveyor, specially designed to change one pallet for another which is standardised, in either the input or the output of an automatic goods flow system. No additional manual handling is necessary. The use of non-standard pallets in an automatic warehouse can cause a stoppage in the process. The pallet exchanger offers an economical solution that will satisfy your needs in quality warehousing. Great precision, with high performance and protection for your containers.
In order to design a reliable and safe system, it is important to have all the products and pallets defined in advance, before confirming the order.
It is essential that the load is stable and that the dimensions do not change.
Technical characteristics:
Example pallet exchange process, two in origin and one in destination:
Original pallet 1 (WxLxH) = 800 x 1200 x 145 mm
New pallet 1 (WxLxH) = 1100 x 1100 x 135 mm or 1000 x 1200 x 145 mm
Original pallet 2 (WxLxH) = 1000 x 1200 x 145 mm
New pallet 2 (WxLxH) = 1100 x 1100 x 135 mm
- Maximum load capacity: 1500 Kg.
- Exchange capacity: we recommend a maximum of 90 exchange processes per hour and system.
- Working temperature: 0°C – 40°C
- With eccentric connecting rod lift table with chain conveyor.
- Compressed air consumption: Air consumption depends on the pace of work, but may be up to a maximum (90 pallets / hr) of around 400 nl/hr (6 bar).
- The cover sketch shows the pallet exchanger system.
Calculation of capacity according to the example given:
| Operation | mm | seg. |
| Pallet entry | 2300 | 8,47 |
| Lift the pallet | 1,50 | |
| Close front and back plates | 4,00 | |
| Close side plates | 2,00 | |
| Lower pallet | 1,50 | |
| Remove old pallet and place new pallet | 2300 | 8,47 |
| Lift pallet | 1,50 | |
| Open all plates | 4,00 | |
| Lower pallet | 1,50 | |
| Remove pallet | 1800 | 6,95 |
| Total operation/pallet | 39,89 | |
| Pallets/hour | 90,24 |
