In the range of robot palletiser made by Tongli, the single-column robot palletiser represents the simplest and most compact model.

The single-column robot palletiser can handle bags containing stable, aerated or powdery products, permitting partial overlapping of the bags in the layer along both the top and sides, offering flexible format changes.

Its extreme simplicity makes it possible to palletise even on pallets sitting directly on the floor.

The machine features a sturdy rotating column with a rigid horizontal arm connected to it that can slide vertically along the column. The horizontal arm has a bag pick-up pincer mounted on it that slides along it, rotating around its vertical axis.The machine takes the bags one at a time from the roller conveyor on which they arrive and places them at the point assigned by the program.The horizontal arm descends to the necessary height so that the pincer can pick up the bags from the bag infeed roller conveyor and then it ascends to permit free rotation of the main column.

The pincer traverses along the arm and rotates around its axis to place the bag in the position assigned by the programmed palletising pattern.

The arm is positioned at the required height and the pincer opens to place the bag on the pallet being formed. At this point, the machine returns to the starting point and is ready for a new cycle.

The special construction solution gives the single-column robot palletisers unique features:

• Possibility of palletising from several pickup points, in order to handle bags from different bagging lines in one or more palletising points.
• Possibility of palletizsng on pallets set directly on the floor.
• Very compact size

The machine features a PLC-controlled operating system.

Through special programs, the machine can perform virtually any type of palletising program.

The format and program changes are carried out automatically and very quickly.
