Apparatus and method for detecting rows of objects

摘要

A depalletizer is provided for grasping and removing the rows of objects stacked upon a pallet. The depalletizer is equipped with feelers which probe the top layer on the pallet in order to find out which is the initial row present in the top layer. The probing cycle is carried out so that all the rows present in the top layer are detected, whereupon grasping of that initial row is triggered. The feelers also detect whether the top layer is oriented horizontally.
