Abstract

Abstract A machine for disassembling damaged pallets of the wood type. The pallet is machine disassembled in a manner wherein the undamaged board or stringers may again be used in a reassembled pallet. The machine includes a platform having means for retaining the manually placed pallet in a fixed lateral position and a plate positionable on the deck side of the wood pallet for retention of the pallet in a vertical position. A hydraulically driven engaging arm is positioned above the platform to engage the stringer longitudinally and in a lateral direction. The arm is moved horizontally from a first, second, or third position to forceably engage one, two, or all three stringers. The retaining means assures that no additional damage is imparted to the slats or spacers.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 120 words
A machine for disassembling wood pallets of the type having deck and base boards and stringers comprising a structure including: a platform for placing said pallet thereon; an engaging arm and means for positioning said arm above said platform at a height of said stringers; a shaft having said arm movably positioned thereon for movement of said arm laterally from one side of said structure to the other side; drive means for moving said arm to engage said stringers; a stop on said platform to restrict said pallet placed on said platform from lateral movement; a plate movable vertically to contact the upper deck to restrict said pallet from vertical movement when said arm is in engagement with said stringers.
Claim 2
Dependent Claim 120 words
A machine for disassembling wood pallets of the type having deck and base boards and stringers comprising a structure including: a platform for placing said pallet thereon; an engaging arm and means for positioning said arm above said platform at a height of said stringers; a shaft having said arm movably positioned thereon for movement of said arm laterally from one side of said structure to the other side; drive means for moving said arm to engage said stringers; a stop on said platform to restrict said pallet placed on said platform from lateral movement; a plate movable vertically to contact the upper deck to restrict said pallet from vertical movement when said arm is in engagement with said stringers.
Claim 3
Dependent Claim 25 words
The machine of claim 1 wherein said stop is on both sides of said platform to permit lateral contact with said pallet from either direction.
Claim 4
Dependent Claim 30 words
The machine of claim 1 wherein said lateral movement is controlled from any position between said structure, to thereby permit the removal of one, or more stringers from said pallet.
Claim 5
Dependent Claim 18 words
The machine of claim 1 wherein said shaft is a hydraulic arm and said movement is reciprocal movement.
Claim 6
Dependent Claim 20 words
The machine of claim 1 wherein said plate is of a size greater than the upper deck of said pallet.
Claim 7
Dependent Claim 19 words
The machine of claim 1 wherein said plate further comprises hydraulic means for moving said plate up and down.
