METHOD FOR PRODUCING LARGE STACKS OF LARGE FORMAT SHEETS

摘要

The invention relates to a method for producing large stacks of large-format sheets. In order to bridge a vertical distance between a feeding level of the sheets and a floor level, a stacking platform is designed as a stack-accommodating table (2) that can be moved vertically up and down. A pallet (10) is placed on the stack-accommodating table (2), on which pallet the sheets are stacked to formed stacks. The accommodating table is moved into an upper end position by means of a lifting device, and the sheets are continuously fed to the pallet. The stack-accommodating table is continuously lowered together with the pallet during the continuous feeding in order to ensure uniform stack formation. When the desired stack height is reached, the stack-changing device (11) moves between two sheets and completely separates said two sheets from each other. The subsequent stack is formed on the top side of the insertion bottom. The insertion bottom is continuously lowered, while the accommodating table moves into a lower end position of the accommodating table at the height of the floor region and the pallet is transported away together with the formed stack. Then the stack-accommodating table is moved to the height of the stack-changing device together with a new, empty pallet and the stack-changing device moves back into the initial position thereof horizontally and thus unloads the stack being formed onto the empty pallet. Thereafter the pallet, or rather the stack-accommodating table, is continuously lowered again until the desired stack height is reached and the stack-changing device moves between two sheets again in order to separate the stacks. The method is characterized in that an adapter pallet (1) is used once at the start of the continuous stack formation.
