Abstract:
Method for sorting rolls of paper and paperboard for shipment into a desired sequence based on customer orders, characterized in that the method comprises the steps ofimporting a roll to be sorted to an infeed conveyor (2), selecting from at least two first conveyors (3, 4, 5) a conveyor onto which the roll is to be transferred, transferring the roll onto the selected conveyor so that its leading end remains at the receiving end of said selected conveyor, transferring rolls onto said first conveyors (3, 4, 5) in a similar fashion so that the rolls thus placed onto the conveyors remain in a close disposition to each other so as to form a group of end-to-end abutting rolls until at least one of said first conveyors contains a roll group forming a unit load for an upender lift. transferring the rolls onto a second conveyor (6, 7, 8 or 9), and removing the rolls from the system onto an outfeed conveyor (9) as roll groups forming a unit load for an upender lift so that the roll groups are taken off from the sequence of rolls resting on the conveyor being unloaded at the interface between said conveyor (6, 7, 8) being unloaded and the successive unloading conveyor (10).
