Pharmaceutical products in particular are often palletised on plastic or other top quality skids in the factory but are switched to cheaper expendable pallets for distribution. A pallet transfer device gives the option to put goods on to the most suitable type of unit for distribution immediately prior to shipping. A producer may not know the destination of the goods at time of production, but now has the flexibility to transfer them to the most suitable pallet for the market concerned.
Ideas are now switching towards systems which recline the load temporarily and return just the pallet to its original position for exchange. The Premier Pallet Changer does just this. It begins by gripping the pallet and enclosing the load from top and sides then reclining everything through 105 degrees. The pallet can now be detached from the product and returned to ground level for removal.
The importance of this operation is that it is no longer necessary to touch the pallet by hand. Increasingly, companies are instituting systems which preclude any manual lifting of loads over 25kgs, especially anything as awkward to handle as a pallet. The Pallet Changer can be used in conjunction with a pallet stacker and dispenser, one to accumulate the old pallet and the other to dispense the new one.
The challenge with this style of inverter is to make it as universally workable with all types of load and sizes of pallet if it is to become a serious competitor to the traditional machines. One option is to tip the product back into a ‘V’. This works well with some goods, but forces everything to one corner of the pallet; also bagged goods tend to collapse when resting on their edge in this way.
Cost is obviously a big factor in the decision making process when buying a pallet inverter. The newer styles of Pallet Changer rely heavily on multiple hydraulic functions and sophisticated control systems. With anything up to 5 moving functions on a machine, the use of PLC control is inevitable. Premier have now successfully rationalised this process and produced a simpler, universal model with options to upgrade with additional features.
