Stacker apparatus for multiple corrugated sheets

Abstract

Abstract A STACKER APPARATUS FOR FORMING AR AN UNLOADING ZONE A PLURALITY OF STACKS OF CORRUGATED SHEETS, SAID STACKS HAVING THEIR LEAD EDGES ALIGNED, THE STACKS BEING FREE OF INTERLEAVING. THE STACKER INCORPORATES A TAKEOFF TABLE AND A TRANSVERSELY DIRECTED ALIGNMENT BART, THE SHEETS TO BE STACKED BEING SERIALLY FED BENEATH A SQUARING BELT ASSEMBLY INCLUDING A TRANSVERSE BELT OVERLYING AND DRIVEN TO FEED A PLURALITY OF SIDE BY SIDE SHEETS AT ONE TIME AGAINST THE BAR. THE LOWER PERIPHERAL PORTION OF THE BELT ENGAGES THE UPPER SURFACES OF THE SHEETS UNDER CONTROLLED DOWNWARD PRESSURE AND URGES THE SHEETS CONTINUOUSLY AGAINST THE BAR, THE SHEET ENGAGING PORITON OF THE BELT BEING GUIDED AGAINST TILTING MOVEMENT AND BEING CONSTRAINED TO BE SHIFTED IN A VERTICAL PLANE ONLY BY THE PROGRESSIVE ACCUMULATION OF SHEETS AGAINST THE ALIGNMENT BAR. MEANS ARE PROVIDED FOR CLEARING THE ALIGNMENT BAR AND BELT ASSEMBLY AT THE COMPLETION OF THE FORMATION OF A SERIES STACKED OF DESIRED HEIGHT. THE PROGRESSIVE URGING FORCES OF THE SQUARING BELT ASSEMBLY, COUPLED WITH THE VERTICAL MOVEMENT AND NON-TILTABILITY OF THE FEED PORTION OF THE SQUARING BELT ASSEMBLY ELIMINATE ANY INTERLEAVING OF THE STACKS STORED AGAINST THE ALIGNMENT BAR.
