The pallet changing system involves the transfer of materials thanks to the Master Inverter pallet changer, able to change the pallet from wood to plastic/aluminum with a bidirectional movement towards production and vice versa. The Master Inverter in-line pallet changer allows the transfer of the product by pushing and holding on three sides. The Master Inverter device is inserted inside a dedusting cabin.
The pallet change operation is specially coordinated with the load dedusting process to prevent the transit of the wooden pallet from contaminating that of the plastic pallet.
In addition, this logistics line provides the dedust of materials entering into the warehouse by an air sheet (installed on the frame of the Master Inverter). The unit consists of a dedusting cabin (which contains the pallet changer) equipped with interlocked doors and a unit for blowing and air purification. In addition, there’s the option of an integrated additional blowing system with compressed air nozzles or a film cutting machine positioned at the beginning of the line.
This logistics system guarantees a faster pallet change than the stand-alone machine thanks to the pallet warehouses that are equipped with conveyors for the collection and delivery of wooden and plastic pallets. The automatic pallet changer is equipped with an adaptive centering system with sonar measurement that allows the goods to be centered inside the new pallet while compensating for the difference in size of the two pallets (if they are different). The security of the system is guaranteed through the use of a perimeter of metal meshes and man photocells for access control.
How does the dedusting cabin work?
The cabin is made with stainless steel walls with a scotch Brite finish, equipped with ceiling lights for internal lighting. The operating principle of pulverization is based on the action of high-speed air jets filtered through a HEPA filter. The launch of the air jets comes from adjustable and nozzle diffusers, mounted on a C-frame secured to the Master inverter. The recirculated air, before being filtered by the HEPA filter, passes through n. 2 prefilters G4. The maintenance of the prefilters is foreseen inside the cabin, through removable frames. A high-pressure electric fan allows the recirculation of the air and the expulsion of 10% of the same, after filtration in order to keep the interior at negative pressure. The HEPA filter is positioned in the upper external part of the cabin. The clogging control of the HEPA filter is managed by a MAGNEHELIC differential pressure gauge (scale 0-500 la)
