Abstract:
A machine for disassembling pallets by cutting fastening means used to secure boards of varying thickness to stringers of pallets, said machine comprising: a horizontal blade, two wheels entrained by the blade, one of which is driven by drive means, a tight fitting resilient flat belt in a peripheral groove in each of the wheels, a frame, a table and means for vertically adjusting the table including first and second jack assemblies interconnected by at least one transverse member, each jack assembly having first and second levers pivotally connected together at mid portions of each lever; a first end of the first lever being pivotally connected to the table; a first end of the second lever being pivotally connected to the frame; a second end of the first lever being in rolling contact with the frame, a second end of the second lever being in rolling contact with an underside of the table; means for raising the jack assemblies including a pair of interconnected links; a first one of the links having a first end pivotally connected to the transverse bar; a second one of the links having a first end pivotally joined to the frame and a second end pivotally joined to the first link and spaced from a second end of the first link so that a portion of the first link extends beyond the second link and an electrical linear actuator for moving the links and the jack assemblies to vertically adjust the table so that a pallet on the table will be aligned with the saw blade thereby allowing the blade to pass between the boards and the stringers as pallets moved across the table by an operator and the fastening means will be cut thereby disassembling the pallet.
