Definitions

  • the invention relates to a plant for supplying products to be palletized and a process for stacking mixed pallets.
  • mixed pallets is meant pallets not stacked with a single type of product but those which contain various types of products, often in varying quantities.
  • the products to be palletised when of a same type, are stocked in a determined number in containers positioned on relative support units.
  • products to be palletised are arranged on relative fixed shelves positioned internally of storage warehouses, among which the operator whose job it is to compose the pallets moves, displacing from a type of product to another and collecting, one by one, the quantity of the relative product required for stacking the pallet.
  • the operator charged with making up the mixed pallet is stationary in a work station, known as a picking station, to which the various types of product are automatically transported.
  • the operator thus collects the number of units required for making up the pallet for each product arriving at the picking station, after which the remaining products are returned to the corresponding stocking zones inside the warehouse.
  • goods-to-man processes are performed by using automatic machines which enable collection of the various products from the warehouse, transport thereof up to the picking station and repositioning of the products not collected by the operator newly in the warehouse.
  • the automatic machines used comprise a trajectory along which the products to be palletised are moved, externally of which the picking station and the storage warehouse are positioned.
  • the storage warehouses are generally vertically-developing and are provided with stacker cranes, i.e.
  • three-axis robots linearly mobile on tracks, which enable products positioned at different heights in the warehouse to be picked and positioned on roller planes and/or conveyor belts from which they will be removed to form the relative pallet. Products not picked are then repositioned on the conveyor rollers and newly returned to the storage warehouse by stacker cranes.
  • known-type plants comprise a first storage zone served by transport shuttles and in which the main products are stored, and a vertically-developing second storage zone served by stacker cranes and containing the secondary products.
