The multi-pallet model IMP.A.C. 13 AMP can palletize the product from up to 5 separate bagging lines at a maximum combined rate of 1100 bags/h. The palletizer is supplied with holding conveyors, one for each product, which accumulate the number of bags required for a complete pallet. When a holding conveyor has accumulated the preset number of bags, it transfers the bags into the palletizer. The palletizer adjusts automatically to handle the bag dimensions from the particular conveyor. Each incoming bag is flattened to a uniform compacted height, orientated, and then transferred to the layer preforming section. Each completed layer is then transferred to the loading station where a sliding gate opens and deposits it onto the pallet. The pallet is lowered automatically, each time a layer has been deposited. When a pallet has received the preset number of layers, it is automatically transferred to a holding conveyor, and an empty pallet is simultaneously moved into the loading zone. The entire operation is controlled by a PLC, which can be programmed to palletize bags of different dimensions, layers patterns and number of layers.
