Abstract
A method for detecting the position of stacked flat material wherein at least one light beam is directed onto a side of a pile of the flat material, is reflected therefrom and is evaluated as a measure of the position, includes directing the at least one light beam not only onto the side of the flat material pile, but also onto a region above a top edge of the pile, and utilizing regions with reflection and without reflection from the pile side for determining the position of the top edge of the pile; and a device for performing the foregoing method.
Claims29
A method for detecting the position of stacked flat material, wherein at least one light beam is directed onto a side of a pile of the flat material, is reflected therefrom and is evaluated as a measure of the position, which comprises directing the at least one light beam not only onto the side of the flat material pile, but also onto a region above a top edge of the pile, and utilizing regions with reflection and without reflection from the pile side for determining the position of the top edge of the pile.
A device for performing a method of detecting the position of stacked flat material, comprising a spacing sensor with at least one light source and at least one receiver for reflected light, and an evaluation device, said spacing sensor being arranged so that the at least one light beam is directed both onto the side of a pile of the stacked flat material and onto a region above a top edge of the pile, said evaluation device being set up for determining the position of the top edge of the pile by way of regions with reflection and without reflection.
