Definitions

• the present invention relates to a method for handling loads by tilting and to a device implementing the method significantly improving the handling of any loads, in particular in the field of active storage.
• the term “charges” will denote any objects such as, for example, packaged or unpackaged goods.
• load transfer devices are well known for changing pallets under palletized goods, that is to say goods positioned on pallets.
• These transfer devices generally consist of two perpendicular plates forming an L, a first loading plate and a second transfer plate mounted on a frame provided with means ensuring their rotation along an axis parallel to said plates.
• the plates are rotated from a first so-called loading position where the palletized load is supported on the loading plate which extends generally horizontally, the transfer plate then extending vertically, to a second position called transfer where the load is supported on the transfer plate which then extends generally horizontally, the loading plate extending vertically.
• the load is repaletted by changing the initial pallet by a new pallet, of different dimensions or shape, for example, the load then resuming support on the loading plate after tilting.
• a new pallet of different dimensions or shape, for example, the load then resuming support on the loading plate after tilting.
• European patent EP 0.811.569 describing a charge transfer device making it possible to re-palletize a charge.
• the device consists of two perpendicular plates forming an L, a first loading plate capable of moving vertically relative to a second transfer plate comprising an opening for discharging old pallets, said plates being mounted on a frame provided with means ensuring their rotation along an axis parallel to said plates.
• the palletized load being positioned on a new pallet
• the load assembly, old pallet and new pallet is positioned on the loading platform which extends generally horizontally so that the old pallet is at the right of the opening of evacuation of the transfer plate
• the plates are tilted until the transfer plate extends generally horizontally so that the old pallet falls in an articulated case under the transfer plate by a rotating arm
• the plate loading is moved horizontally until the new pallet is in contact with the load and finally, the trays are returned to their initial position, the load thus repaletted then being ready to be removed by a self-propelled handling means such as a forklift for example.
• a self-propelled handling means such as a forklift for example.
• the palletized loads are conventionally centered on the pallets causing, during the rotation of the plates, a drop in the loads on the transfer plate, which risks damaging the loads.
• these devices are conventionally used on logistics platforms where palletized loads are unloaded from trucks to be stored in a first storage area before being positioned in racks where the loads are accessible to operators who repackage them.
