APEX Automation and Robotics have recently installed and commissioned an automatic palletiser for PET bottles that can run at a production rate of more than 5000 bottles per hour.
This automatic palletiser included a takeout module that can unload the blow moulding machine, and a conveyor for marshalling the bottles before they are collected for palletising. The system can handle a range of different size bottles without needing to adjust the conveyor height.
A pallet lifter raises the pallet to the palletising level and a cardboard layer pad is loaded on the pallet. The bottles are collected one row at a time until a layer is formed then stacked on the top of the layer pad. When a layer is complete, a pallet lifter drops one bottle height for the next sheet to be loaded and then the next layer of bottles is palletised.
This custom-designed pallet lifter drops the finished pallet all the way down to floor level so that it can be handled by a pallet jack without requiring a fork truck in the production area.
The automatic palletising system was controlled by a programmable logic controller with a user-friendly human machine interface. Safeguarding included a set of Cat 4 light curtains for easy access to the pallet for loading and unloading.
Apex Automation and Robotics have developed a wide range of automatic machines, including automatic palletisers, to handle various sizes and shapes of plastic bottles, as well as robotic systems for complex packing and palletising configurations.
