Title: A Pallet Stacker
Inventor: MICHAEL ROBERT
IPC: B65G69/10
Filed: 2022-08-11
Abstract: The invention in a preferred embodiment comprises a stacker 1 for use with pallets, 
comprising a chamber 2, a hydraulically driven platform 9 and vibrators 8. The stacker is 
formed to enable stacking of parcels 5 wherein the platform 9 receives a pallet 10 and 
holds it at or adjacent to the top of the chamber. Parcels 5 packed with a fluid material 
(eg granular material) may be loaded onto the platform 9 which is then able to be lowered 
with respect to the chamber. The arrangement is such that as this occurs the vibrators 8 
cause walls of the chamber to vibrate substantially without contacting the pallet 10 such 
that the vibrations transfer to the parcels to move them away from the walls. The result is 
that the parcels become more closely packed on the pallet and the fluid material in them 
becomes more densely settled.
