Four-column
Four-column
The four-column robot palletizer features a pincer that moves along three Cartesian axes as it rotates around its vertical axis.
This permits trouble-free handling of bags that are not completely filled or that contain aerated or powdery material, guaranteeing outstanding flexibility.
The Concetti machine consists of a rigid structure.
Sliding on the structure vertically is a frame with an incorporated pincer, bag infeed roller conveyor and two sliding trapdoors that act as the layer-formation platform. The pincer takes one bag at a time from the roller conveyor and places it on the platform, at a point assigned by the palletizing program. Once the bag has been deposited, the pincer returns to the starting position, ready for the next bag.
Since the bags can be placed in any position on the layer-formation platform, the bags can also be overlapped partially along the top or the side, thus giving good stability and shape to the palletized load, regardless of their shape and type (valve, open-mouth, paper, raffia, PE, etc.), how full they are or the type of material they contain.
Once a layer has been completed, it is compacted on all four sides and the trapdoors open to unload the layer onto the pallet being formed.
After this operation, the frame is elevated by the thickness of the layer and the trap doors close again in order to palletize the next layer.
After the trapdoors have closed, the frame can descend slightly to press the upper surface of the layer that was just transferred to the pallet. The completed pallets are removed by the evacuation roller conveyor and transferred to the finished pallet parking roller conveyor.
Program changes are automatic and take just a few seconds, guided by the PLC and the actuators installed on the machine. This makes it possible to handle different formats or use different palletizing patterns in a very flexible manner.
The four-column robot palletizer comes complete with safety devices compliant with current standards.
