A method for automatic replace the stack on a sheet feeder of a sheet-fed printing press

摘要

The invention relates to a method for automatic replace the stack on a sheet feeder of a sheet-fed printing press by means of a nonstop - device. The pile is accomplished in that, when the reaching of a definable stack height of the residual sheet pile, the carrier bars of the stack rake above the auxiliary stack frame be moved into the pallet.It is disadvantageous that carrying bars according to the outlet from the receiving grooves on the rear part of the auxiliary stack frame meet, and collide with this.The object of the invention, therefore, a method for the guidance of the stack to develop rake, by means of which a collision with the auxiliary stack frame is avoided.This object is achieved in that, after the introduction of the carrying bars (421) a relative speed between the lifting speed of the carrying bars (421) and the processing speed of displacement of the pallet (6) is generated, in such a way that the carrying bars (421) are deflected in such a way that the front ends of the carrying bars (421) in a clear height above the rear part of the auxiliary stack frame (41) are guided.
