Robotic palletisers and depalletisers are ideal for automating heavy, repetitive lifting tasks, maximising throughput and minimising errors during stacking and unstacking. These may include containers, cartons or other packaging units. The use of robotic palletizers and depalletizers in a warehouse depends on the processes, the type and variety of products, and the throughput.
When does it make sense to use palletizers and depalletizers?
Handling devices seamlessly integrated
At our Customers BIG and Lantmännen, robots are used which stack cardboard boxes from production lines onto pallets. Each packaging unit is commissioned stating the packaging pattern and hence palletized by the device. At BIG, the article and the associated cardboard box type are notified, at Lantmännen, each cardboard box features a barcode label which is scanned when the box is delivered to the robot. Portal devices are employed at Dräxlmaier. Here, the totes are depalletized from stacks onto pallets or shipping containers are stacked onto pallets and support frames. In this case as well, corresponding stacking patterns are created by sequencing (order picking sequence) as different container quantities entail different stacking schemes. The handling devices in the JIT/JIS warehouses are designed redundantly to be able to continue (de-)palletising and sequencing when a device fails. At Dräxlmaier, both devices are used simultaneously - one for depalletizing, one for palletising.
