摘要： Method for controlling a sheet feeding device (1) comprising an elevator (2) for a stack of sheets, and an air supply system (3) configured to supply and direct one of more air streams towards an upper region (4) of the sheet feeding device for floating a plurality of upper sheets of the stack of sheets, wherein the elevator comprises a vertically movable support (5) for supporting the stack of sheets from below, wherein the sheet feeding device comprises an optical sensor (6) positioned adjacent the floated sheets pot for measuring light reflected from the floated sheets at a plurality of different heights, wherein the method comprises the steps of: continuously deriving from the optical sensor a density reading (DR) indicating the density of sheets floated, continuously deriving an average density (AD) based on a plurality of density readings, continuously deriving an upper density limit (UDL) based on the average density multiplied by a predetermined upper density limit factor (UDLF), continuously deriving a lower density limit (LDL) based on the average density multiplied by a predetermined lower density limit factor (LDLF), adjusting a first operating parameter (OP) of the sheet feeding device should the density reading exceed the upper density limit, wherein the adjustment of the first operating parameter is such as to decrease the density of floated sheets, and adjusting the first operating parameter of the sheet feeding device should the density reading subceed the lower density limit, wherein the adjustment of the first operating parameter is such as to increase the density of floated sheets. Also, a sheet feeding device connected to a controller configured to operate according to this method.

摘要： A paper feeding device comprises a storage surface for a stack of papers and being adapted to be move vertically between a first, lower end position and a second, upper end position, and a feeding roll for feeding papers from their position on the storage surface and imparting an uppermost sheet of paper a horizontal displacement. A first mounting device comprises a first vertically movable, preferably pivotable housing adapted to mount or suspend a first end of the feeding roll, and a second mounting device comprises a second vertically movable, preferably pivotable housing adapted to mount or suspend a second end of the feeding roll opposite to the first end of the feeding roll. By providing the first and second housings pivotable independently of each other and an intermediate axle, the feeding roll adapts to a non-uniform stack of papers, improving the reliability of the feeding.

摘要： A method for feeding sheets of paper comprises the following steps: providing a stack of papers on a storage surface of a paper feeding device; providing a flow of air for separating an uppermost sheet of paper from the rest of the stack of papers; determining the vertical position of the uppermost sheet of paper; adjusting the flow of air in dependence on the determined vertical position of the uppermost sheet of paper; and repeating the steps of determining the vertical position of the uppermost sheet of paper and adjusting the flow of air in dependence on the determined vertical position of the uppermost sheet of paper. During continuous operation, the flow of air is controlled in cycles with one part of the cycle, preferably the first part of the cycle, with a higher flow of air, and one part of the cycle, preferably the second part of the cycle, with a lower flow of air. By imparting the uppermost sheet of paper a pulsating movement up and down, the problems associated with electrostatic charging are mitigated.
