Abstract: A tool and a method for depalletizing piles of objects separated by sheets are described herein. The tool comprises a plate assembly for insertion between the highest pile from the piles of objects and the next separator sheet. The plate assembly has a fixed portion and a tip provided at a distal end thereof and is movable between a detecting position, wherein an upward displacement of the tip is allowed relative to the fixed portion, and a depalletizing position, wherein the tip is immobilized relative to the fixed portion. The tool further comprises a plate sensor for detecting the displacement of the tip relative to the fixed portion and for generating a first detection signal responsive to said displacement, and a pressure assembly that defines a gripper with the plate assembly for receiving the highest pile of objects and for selectively applying pressure thereon.
